+ - There are two schools of thought when it comes to splitting a long
+   logical line into multiple lines.  Some people push the second and

+   a binary operator, so that the result looks like a parse tree when
+   you turn your head 90-degrees counterclockwise:
+
+        if (the_beginning_of_a_very_long_expression_that_has_to
+	    || span_more_than_a_single_line_of_the_source_text) {

+   be easier to read.  Again, just do not mix styles in the same part
+   of the code and mimic existing styles in the neighbourhood.
+
+ - When splitting a long logical line, with everything else being
+   equal, it is preferable to split after the operator at higher
+   level in the parse tree.  That is, this is more preferable:

+
+For Python scripts:
+
+ - We follow PEP-8 (http://www.python.org/dev/peps/pep-0008/).
+
+ - As a minimum, we aim to be compatible with Python 2.6 and 2.7.
+
+ - Where required libraries do not restrict us to Python 2, we try to
+   also be compatible with Python 3.1 and later.
+
+ - When you must differentiate between Unicode literals and byte string
+   literals, it is OK to use the 'b' prefix.  Even though the Python
+   documentation for version 2.6 does not mention this prefix, it has
+   been supported since version 2.6.0.
+
+Error Messages
+
+ - Do not end error messages with a full stop.
+
+ - Do not capitalize ("unable to open %s", not "Unable to open %s")
+
+ - Say what the error is first ("cannot open %s", not "%s: cannot open")
+
+
+Writing Documentation:
+
+ Most (if not all) of the documentation pages are written in the
+ AsciiDoc format in *.txt files (e.g. Documentation/git.txt), and
+ processed into HTML and manpages (e.g. git.html and git.1 in the
+ same directory).
+
+ The documentation liberally mixes US and UK English (en_US/UK)
+ norms for spelling and grammar, which is somewhat unfortunate.
+ In an ideal world, it would have been better if it consistently
+ used only one and not the other, and we would have picked en_US
+ (if you wish to correct the English of some of the existing
+ documentation, please see the documentation-related advice in the
+ Documentation/SubmittingPatches file).
+
+ Every user-visible change should be reflected in the documentation.
+ The same general rule as for code applies -- imitate the existing
+ conventions.
+
+ A few commented examples follow to provide reference when writing or
+ modifying command usage strings and synopsis sections in the manual
+ pages:
+
+ Placeholders are spelled in lowercase and enclosed in angle brackets:
+   <file>
+   --sort=<key>
+   --abbrev[=<n>]
+
+ Possibility of multiple occurrences is indicated by three dots:
+   <file>...
+   (One or more of <file>.)
+
+ Optional parts are enclosed in square brackets:
+   [<extra>]
+   (Zero or one <extra>.)
+
+   --exec-path[=<path>]
+   (Option with an optional argument.  Note that the "=" is inside the
+   brackets.)
+
+   [<patch>...]
+   (Zero or more of <patch>.  Note that the dots are inside, not
+   outside the brackets.)
+
+ Multiple alternatives are indicated with vertical bar:
+   [-q | --quiet]
+   [--utf8 | --no-utf8]
+
+ Parentheses are used for grouping:
+   [(<rev>|<range>)...]
+   (Any number of either <rev> or <range>.  Parens are needed to make
+   it clear that "..." pertains to both <rev> and <range>.)
+
+   [(-p <parent>)...]
+   (Any number of option -p, each with one <parent> argument.)
+
+   git remote set-head <name> (-a | -d | <branch>)
+   (One and only one of "-a", "-d" or "<branch>" _must_ (no square
+   brackets) be provided.)
+
+ And a somewhat more contrived example:
+   --diff-filter=[(A|C|D|M|R|T|U|X|B)...[*]]
+   Here "=" is outside the brackets, because "--diff-filter=" is a
+   valid usage.  "*" has its own pair of brackets, because it can
+   (optionally) be specified only when one or more of the letters is
+   also provided.
+
+  A note on notation:
+   Use 'git' (all lowercase) when talking about commands i.e. something
+   the user would type into a shell and use 'Git' (uppercase first letter)
+   when talking about the version control system and its properties.
+
+ A few commented examples follow to provide reference when writing or
+ modifying paragraphs or option/command explanations that contain options
+ or commands:
+
+ Literal examples (e.g. use of command-line options, command names, and
+ configuration variables) are typeset in monospace, and if you can use
+ `backticks around word phrases`, do so.
+   `--pretty=oneline`
+   `git rev-list`
+   `remote.pushdefault`
+
+ Word phrases enclosed in `backtick characters` are rendered literally
+ and will not be further expanded. The use of `backticks` to achieve the
+ previous rule means that literal examples should not use AsciiDoc
+ escapes.
+   Correct:
+      `--pretty=oneline`
+   Incorrect:
+      `\--pretty=oneline`
+
+ If some place in the documentation needs to typeset a command usage
+ example with inline substitutions, it is fine to use +monospaced and
+ inline substituted text+ instead of `monospaced literal text`, and with
+ the former, the part that should not get substituted must be
+ quoted/escaped.

-
-  - git-status did not honor core.excludesFile configuration like
-    git-add did.
-
-  - git-annotate did not work from a subdirectory while
-    git-blame did.
-
-  - git-cvsserver should have disabled access to a repository
-    with "gitcvs.pserver.enabled = false" set even when
-    "gitcvs.enabled = true" was set at the same time.  It
-    didn't.
-
-  - git-cvsimport did not work correctly in a repository with
-    its branch heads were packed with pack-refs.
-
-  - ident unexpansion to squash "$Id: xxx $" that is in the
-    repository copy removed incorrect number of bytes.
-
-  - git-svn misbehaved when the subversion repository did not
-    provide MD5 checksums for files.
-
-  - git rebase (and git am) misbehaved on commits that have '\n'
-    (literally backslash and en, not a linefeed) in the title.
-
-  - code to decode base85 used in binary patches had one error
-    return codepath wrong.
-
-  - RFC2047 Q encoding output by git-format-patch used '_' for a
-    space, which is not understood by some programs.  It uses =20
-    which is safer.
-
-  - git-fastimport --import-marks was broken; fixed.
-
-  - A lot of documentation updates, clarifications and fixes.

-GIT v1.5.6.3 Release Notes
-==========================
-
-Fixes since v1.5.6.2
---------------------
-
-* Setting core.sharerepository to traditional "true" value was supposed to make
-  the repository group writable but should not affect permission for others.
-  However, since 1.5.6, it was broken to drop permission for others when umask is
-  022, making the repository unreadable by others.
-
-* Setting GIT_TRACE will report spawning of external process via run_command().
-
-* Using an object with very deep delta chain pinned memory needed for extracting
-  intermediate base objects unnecessarily long, leading to excess memory usage.
-
-* Bash completion script did not notice '--' marker on the command
-  line and tried the relatively slow "ref completion" even when
-  completing arguments after one.
-
-* Registering a non-empty blob racily and then truncating the working
-  tree file for it confused "racy-git avoidance" logic into thinking
-  that the path is now unchanged.
-
-* The section that describes attributes related to git-archive were placed
-  in a wrong place in the gitattributes(5) manual page.
-
-* "git am" was not helpful to the users when it detected that the committer
-  information is not set up properly yet.
-
-* "git clone" had a leftover debugging fprintf().
-
-* "git clone -q" was not quiet enough as it used to and gave object count
-  and progress reports.
-
-* "git clone" marked downloaded packfile with .keep; this could be a
-  good thing if the remote side is well packed but otherwise not,
-  especially for a project that is not really big.
-
-* "git daemon" used to call syslog() from a signal handler, which
-  could raise signals of its own but generally is not reentrant.  This
-  was fixed by restructuring the code to report syslog() after the handler
-  returns.
-
-* When "git push" tries to remove a remote ref, and corresponding
-  tracking ref is missing, we used to report error (i.e. failure to
-  remove something that does not exist).
-
-* "git mailinfo" (hence "git am") did not handle commit log messages in a
-  MIME multipart mail correctly.
-
-Contains other various documentation fixes.

-GIT v1.6.0.2 Release Notes
-==========================
-
-Fixes since v1.6.0.1
---------------------
-
-* Installation on platforms that needs .exe suffix to git-* programs were
-  broken in 1.6.0.1.
-
-* Installation on filesystems without symbolic links support did not
-  work well.
-
-* In-tree documentations and test scripts now use "git foo" form to set a
-  better example, instead of the "git-foo" form (which is an acceptable
-  form if you have "PATH=$(git --exec-path):$PATH" in your script)
-
-* Many commands did not use the correct working tree location when used
-  with GIT_WORK_TREE environment settings.
-
-* Some systems needs to use compatibility fnmach and regex libraries
-  independent from each other; the compat/ area has been reorganized to
-  allow this.
-
-
-* "git apply --unidiff-zero" incorrectly applied a -U0 patch that inserts
-  a new line before the second line.
-
-* "git blame -c" did not exactly work like "git annotate" when range
-  boundaries are involved.
-
-* "git checkout file" when file is still unmerged checked out contents from
-  a random high order stage, which was confusing.
-
-* "git clone $there $here/" with extra trailing slashes after explicit
-  local directory name $here did not work as expected.
-
-* "git diff" on tracked contents with CRLF line endings did not drive "less"
-  intelligently when showing added or removed lines.
-
-* "git diff --dirstat -M" did not add changes in subdirectories up
-  correctly for renamed paths.
-
-* "git diff --cumulative" did not imply "--dirstat".
-
-* "git for-each-ref refs/heads/" did not work as expected.
-
-* "git gui" allowed users to feed patch without any context to be applied.
-
-* "git gui" botched parsing "diff" output when a line that begins with two
-  dashes and a space gets removed or a line that begins with two pluses
-  and a space gets added.
-
-* "git gui" translation updates and i18n fixes.
-
-* "git index-pack" is more careful against disk corruption while completing
-  a thin pack.
-
-* "git log -i --grep=pattern" did not ignore case; neither "git log -E
-  --grep=pattern" triggered extended regexp.
-
-* "git log --pretty="%ad" --date=short" did not use short format when
-  showing the timestamp.
-
-* "git log --author=author" match incorrectly matched with the
-  timestamp part of "author " line in commit objects.
-
-* "git log -F --author=author" did not work at all.
-
-* Build procedure for "git shell" that used stub versions of some
-  functions and globals was not understood by linkers on some platforms.
-
-* "git stash" was fooled by a stat-dirty but otherwise unmodified paths
-  and refused to work until the user refreshed the index.
-
-* "git svn" was broken on Perl before 5.8 with recent fixes to reduce
-  use of temporary files.
-
-* "git verify-pack -v" did not work correctly when given more than one
-  packfile.
-
-Also contains many documentation updates.

-GIT v1.6.1.3 Release Notes
-==========================
-
-Fixes since v1.6.1.2
---------------------
-
-* "git diff --binary | git apply" pipeline did not work well when
-  a binary blob is changed to a symbolic link.
-
-* Some combinations of -b/-w/--ignore-space-at-eol to "git diff" did
-  not work as expected.
-
-* "git grep" did not pass the -I (ignore binary) option when
-  calling out an external grep program.
-
-* "git log" and friends include HEAD to the set of starting points
-  when --all is given.  This makes a difference when you are not
-  on any branch.
-
-* "git mv" to move an untracked file to overwrite a tracked
-  contents misbehaved.
-
-* "git merge -s octopus" with many potential merge bases did not
-  work correctly.
-
-* RPM binary package installed the html manpages in a wrong place.
-
-Also includes minor documentation fixes and updates.

-GIT v1.6.1.4 Release Notes
-==========================
-
-Fixes since v1.6.1.3
---------------------
-
-* .gitignore learned to handle backslash as a quoting mechanism for
-  comment introduction character "#".
-  This fix was first merged to 1.6.2.1.
-
-* "git fast-export" produced wrong output with some parents missing from
-  commits, when the history is clock-skewed.
-
-* "git fast-import" sometimes failed to read back objects it just wrote
-  out and aborted, because it failed to flush stale cached data.
-
-* "git-ls-tree" and "git-diff-tree" used a pathspec correctly when
-  deciding to descend into a subdirectory but they did not match the
-  individual paths correctly.  This caused pathspecs "abc/d ab" to match
-  "abc/0" ("abc/d" made them decide to descend into the directory "abc/",
-  and then "ab" incorrectly matched "abc/0" when it shouldn't).
-  This fix was first merged to 1.6.2.3.
-
-* import-zips script (in contrib) did not compute the common directory
-  prefix correctly.
-  This fix was first merged to 1.6.2.2.
-
-* "git init" segfaulted when given an overlong template location via
-  the --template= option.
-  This fix was first merged to 1.6.2.4.
-
-* "git repack" did not error out when necessary object was missing in the
-  repository.
-
-* git-repack (invoked from git-gc) did not work as nicely as it should in
-  a repository that borrows objects from neighbours via alternates
-  mechanism especially when some packs are marked with the ".keep" flag
-  to prevent them from being repacked.
-  This fix was first merged to 1.6.2.3.
-
-Also includes minor documentation fixes and updates.

-GIT v1.6.1 Release Notes
-========================
-
-Updates since v1.6.0
---------------------
-
-When some commands (e.g. "git log", "git diff") spawn pager internally, we
-used to make the pager the parent process of the git command that produces
-output.  This meant that the exit status of the whole thing comes from the
-pager, not the underlying git command.  We swapped the order of the
-processes around and you will see the exit code from the command from now
-on.
-
-(subsystems)
-
-* gitk can call out to git-gui to view "git blame" output; git-gui in turn
-  can run gitk from its blame view.
-
-* Various git-gui updates including updated translations.
-
-* Various gitweb updates from repo.or.cz installation.
-
-* Updates to emacs bindings.
-
-(portability)
-
-* A few test scripts used nonportable "grep" that did not work well on
-  some platforms, e.g. Solaris.
-
-* Sample pre-auto-gc script has OS X support.
-
-* Makefile has support for (ancient) FreeBSD 4.9.
-
-(performance)
-
-* Many operations that are lstat(3) heavy can be told to pre-execute
-  necessary lstat(3) in parallel before their main operations, which
-  potentially gives much improved performance for cold-cache cases or in
-  environments with weak metadata caching (e.g. NFS).
-
-* The underlying diff machinery to produce textual output has been
-  optimized, which would result in faster "git blame" processing.
-
-* Most of the test scripts (but not the ones that try to run servers)
-  can be run in parallel.
-
-* Bash completion of refnames in a repository with massive number of
-  refs has been optimized.
-
-* Cygwin port uses native stat/lstat implementations when applicable,
-  which leads to improved performance.
-
-* "git push" pays attention to alternate repositories to avoid sending
-  unnecessary objects.
-
-* "git svn" can rebuild an out-of-date rev_map file.
-
-(usability, bells and whistles)
-
-* When you mistype a command name, git helpfully suggests what it guesses
-  you might have meant to say.  help.autocorrect configuration can be set
-  to a non-zero value to accept the suggestion when git can uniquely
-  guess.
-
-* The packfile machinery hopefully is more robust when dealing with
-  corrupt packs if redundant objects involved in the corruption are
-  available elsewhere.
-
-* "git add -N path..." adds the named paths as an empty blob, so that
-  subsequent "git diff" will show a diff as if they are creation events.
-
-* "git add" gained a built-in synonym for people who want to say "stage
-  changes" instead of "add contents to the staging area" which amounts
-  to the same thing.
-
-* "git apply" learned --include=paths option, similar to the existing
-  --exclude=paths option.
-
-* "git bisect" is careful about a user mistake and suggests testing of
-  merge base first when good is not a strict ancestor of bad.
-
-* "git bisect skip" can take a range of commits.
-
-* "git blame" re-encodes the commit metainfo to UTF-8 from i18n.commitEncoding
-  by default.
-
-* "git check-attr --stdin" can check attributes for multiple paths.
-
-* "git checkout --track origin/hack" used to be a syntax error.  It now
-  DWIMs to create a corresponding local branch "hack", i.e. acts as if you
-  said "git checkout --track -b hack origin/hack".
-
-* "git checkout --ours/--theirs" can be used to check out one side of a
-  conflicting merge during conflict resolution.
-
-* "git checkout -m" can be used to recreate the initial conflicted state
-  during conflict resolution.
-
-* "git cherry-pick" can also utilize rerere for conflict resolution.
-
-* "git clone" learned to be verbose with -v
-
-* "git commit --author=$name" can look up author name from existing
-  commits.
-
-* output from "git commit" has been reworded in a more concise and yet
-  more informative way.
-
-* "git count-objects" reports the on-disk footprint for packfiles and
-  their corresponding idx files.
-
-* "git daemon" learned --max-connections=<count> option.
-
-* "git daemon" exports REMOTE_ADDR to record client address, so that
-  spawned programs can act differently on it.
-
-* "git describe --tags" favours closer lightweight tags than farther
-  annotated tags now.
-
-* "git diff" learned to mimic --suppress-blank-empty from GNU diff via a
-  configuration option.
-
-* "git diff" learned to put more sensible hunk headers for Python,
-  HTML and ObjC contents.
-
-* "git diff" learned to vary the a/ vs b/ prefix depending on what are
-  being compared, controlled by diff.mnemonicprefix configuration.
-
-* "git diff" learned --dirstat-by-file to count changed files, not number
-  of lines, when summarizing the global picture.
-
-* "git diff" learned "textconv" filters --- a binary or hard-to-read
-  contents can be munged into human readable form and the difference
-  between the results of the conversion can be viewed (obviously this
-  cannot produce a patch that can be applied, so this is disabled in
-  format-patch among other things).
-
-* "--cached" option to "git diff has an easier to remember synonym "--staged",
-  to ask "what is the difference between the given commit and the
-  contents staged in the index?"
-
-* "git for-each-ref" learned "refname:short" token that gives an
-  unambiguously abbreviated refname.
-
-* Auto-numbering of the subject lines is the default for "git
-  format-patch" now.
-
-* "git grep" learned to accept -z similar to GNU grep.
-
-* "git help" learned to use GIT_MAN_VIEWER environment variable before
-  using "man" program.
-
-* "git imap-send" can optionally talk SSL.
-
-* "git index-pack" is more careful against disk corruption while
-  completing a thin pack.
-
-* "git log --check" and "git log --exit-code" passes their underlying diff
-  status with their exit status code.
-
-* "git log" learned --simplify-merges, a milder variant of --full-history;
-  "gitk --simplify-merges" is easier to view than with --full-history.
-
-* "git log" learned "--source" to show what ref each commit was reached
-  from.
-
-* "git log" also learned "--simplify-by-decoration" to show the
-  birds-eye-view of the topology of the history.
-
-* "git log --pretty=format:" learned "%d" format element that inserts
-  names of tags that point at the commit.
-
-* "git merge --squash" and "git merge --no-ff" into an unborn branch are
-  noticed as user errors.
-
-* "git merge -s $strategy" can use a custom built strategy if you have a
-  command "git-merge-$strategy" on your $PATH.
-
-* "git pull" (and "git fetch") can be told to operate "-v"erbosely or
-  "-q"uietly.
-
-* "git push" can be told to reject deletion of refs with receive.denyDeletes
-  configuration.
-
-* "git rebase" honours pre-rebase hook; use --no-verify to bypass it.
-
-* "git rebase -p" uses interactive rebase machinery now to preserve the merges.
-
-* "git reflog expire branch" can be used in place of "git reflog expire
-  refs/heads/branch".
-
-* "git remote show $remote" lists remote branches one-per-line now.
-
-* "git send-email" can be given revision range instead of files and
-  maildirs on the command line, and automatically runs format-patch to
-  generate patches for the given revision range.
-
-* "git submodule foreach" subcommand allows you to iterate over checked
-  out submodules.
-
-* "git submodule sync" subcommands allows you to update the origin URL
-  recorded in submodule directories from the toplevel .gitmodules file.
-
-* "git svn branch" can create new branches on the other end.
-
-* "gitweb" can use more saner PATH_INFO based URL.
-
-(internal)
-
-* "git hash-object" learned to lie about the path being hashed, so that
-  correct gitattributes processing can be done while hashing contents
-  stored in a temporary file.
-
-* various callers of git-merge-recursive avoid forking it as an external
-  process.
-
-* Git class defined in "Git.pm" can be subclasses a bit more easily.
-
-* We used to link GNU regex library as a compatibility layer for some
-  platforms, but it turns out it is not necessary on most of them.
-
-* Some path handling routines used fixed number of buffers used alternately
-  but depending on the call depth, this arrangement led to hard to track
-  bugs.  This issue is being addressed.
-
-
-Fixes since v1.6.0
-------------------
-
-All of the fixes in v1.6.0.X maintenance series are included in this
-release, unless otherwise noted.
-
-* Porcelains implemented as shell scripts were utterly confused when you
-  entered to a subdirectory of a work tree from sideways, following a
-  symbolic link (this may need to be backported to older releases later).
-
-* Tracking symbolic links would work better on filesystems whose lstat()
-  returns incorrect st_size value for them.
-
-* "git add" and "git update-index" incorrectly allowed adding S/F when S
-  is a tracked symlink that points at a directory D that has a path F in
-  it (we still need to fix a similar nonsense when S is a submodule and F
-  is a path in it).
-
-* "git am" after stopping at a broken patch lost --whitespace, -C, -p and
-  --3way options given from the command line initially.
-
-* "git diff --stdin" used to take two trees on a line and compared them,
-  but we dropped support for such a use case long time ago.  This has
-  been resurrected.
-
-* "git filter-branch" failed to rewrite a tag name with slashes in it.
-
-* "git http-push" did not understand URI scheme other than opaquelocktoken
-  when acquiring a lock from the server (this may need to be backported to
-  older releases later).
-
-* After "git rebase -p" stopped with conflicts while replaying a merge,
- "git rebase --continue" did not work (may need to be backported to older
-  releases).
-
-* "git revert" records relative to which parent a revert was made when
-  reverting a merge.  Together with new documentation that explains issues
-  around reverting a merge and merging from the updated branch later, this
-  hopefully will reduce user confusion (this may need to be backported to
-  older releases later).
-
-* "git rm --cached" used to allow an empty blob that was added earlier to
-  be removed without --force, even when the file in the work tree has
-  since been modified.
-
-* "git push --tags --all $there" failed with generic usage message without
-  telling saying these two options are incompatible.
-
-* "git log --author/--committer" match used to potentially match the
-  timestamp part, exposing internal implementation detail.  Also these did
-  not work with --fixed-strings match at all.
-
-* "gitweb" did not mark non-ASCII characters imported from external HTML fragments
-  correctly.

-GIT v1.6.4.3 Release Notes
-==========================
-
-Fixes since v1.6.4.2
---------------------
-
-* "git clone" from an empty repository gave unnecessary error message,
-  even though it did everything else correctly.
-
-* "git cvsserver" invoked git commands via "git-foo" style, which has long
-  been deprecated.
-
-* "git fetch" and "git clone" had an extra sanity check to verify the
-  presense of the corresponding *.pack file before downloading *.idx
-  file by issuing a HEAD request.  Github server however sometimes
-  gave 500 (Internal server error) response to HEAD even if a GET
-  request for *.pack file to the same URL would have succeeded, and broke
-  clone over HTTP from some of their repositories.  As a workaround, this
-  verification has been removed (as it is not absolutely necessary).
-
-* "git grep" did not like relative pathname to refer outside the current
-  directory when run from a subdirectory.
-
-* an error message from "git push" was formatted in a very ugly way.
-
-* "git svn" did not quote the subversion user name correctly when
-  running its author-prog helper program.
-
-Other minor documentation updates are included.

+GIT v1.5.2.1 Release Notes
+==========================
+
+Fixes since v1.5.2
+------------------
+
+* Bugfixes
+
+  - Temporary files that are used when invoking external diff
+    programs did not tolerate a long TMPDIR.
+
+  - git-daemon did not notice when it could not write into its
+    pid file.
+
+  - git-status did not honor core.excludesFile configuration like
+    git-add did.
+
+  - git-annotate did not work from a subdirectory while
+    git-blame did.
+
+  - git-cvsserver should have disabled access to a repository
+    with "gitcvs.pserver.enabled = false" set even when
+    "gitcvs.enabled = true" was set at the same time.  It
+    didn't.
+
+  - git-cvsimport did not work correctly in a repository with
+    its branch heads were packed with pack-refs.
+
+  - ident unexpansion to squash "$Id: xxx $" that is in the
+    repository copy removed incorrect number of bytes.
+
+  - git-svn misbehaved when the subversion repository did not
+    provide MD5 checksums for files.
+
+  - git rebase (and git am) misbehaved on commits that have '\n'
+    (literally backslash and en, not a linefeed) in the title.
+
+  - code to decode base85 used in binary patches had one error
+    return codepath wrong.
+
+  - RFC2047 Q encoding output by git-format-patch used '_' for a
+    space, which is not understood by some programs.  It uses =20
+    which is safer.
+
+  - git-fastimport --import-marks was broken; fixed.
+
+  - A lot of documentation updates, clarifications and fixes.

+GIT v1.5.6.3 Release Notes
+==========================
+
+Fixes since v1.5.6.2
+--------------------
+
+* Setting core.sharedrepository to traditional "true" value was supposed to make
+  the repository group writable but should not affect permission for others.
+  However, since 1.5.6, it was broken to drop permission for others when umask is
+  022, making the repository unreadable by others.
+
+* Setting GIT_TRACE will report spawning of external process via run_command().
+
+* Using an object with very deep delta chain pinned memory needed for extracting
+  intermediate base objects unnecessarily long, leading to excess memory usage.
+
+* Bash completion script did not notice '--' marker on the command
+  line and tried the relatively slow "ref completion" even when
+  completing arguments after one.
+
+* Registering a non-empty blob racily and then truncating the working
+  tree file for it confused "racy-git avoidance" logic into thinking
+  that the path is now unchanged.
+
+* The section that describes attributes related to git-archive were placed
+  in a wrong place in the gitattributes(5) manual page.
+
+* "git am" was not helpful to the users when it detected that the committer
+  information is not set up properly yet.
+
+* "git clone" had a leftover debugging fprintf().
+
+* "git clone -q" was not quiet enough as it used to and gave object count
+  and progress reports.
+
+* "git clone" marked downloaded packfile with .keep; this could be a
+  good thing if the remote side is well packed but otherwise not,
+  especially for a project that is not really big.
+
+* "git daemon" used to call syslog() from a signal handler, which
+  could raise signals of its own but generally is not reentrant.  This
+  was fixed by restructuring the code to report syslog() after the handler
+  returns.
+
+* When "git push" tries to remove a remote ref, and corresponding
+  tracking ref is missing, we used to report error (i.e. failure to
+  remove something that does not exist).
+
+* "git mailinfo" (hence "git am") did not handle commit log messages in a
+  MIME multipart mail correctly.
+
+Contains other various documentation fixes.

+GIT v1.6.0.2 Release Notes
+==========================
+
+Fixes since v1.6.0.1
+--------------------
+
+* Installation on platforms that needs .exe suffix to git-* programs were
+  broken in 1.6.0.1.
+
+* Installation on filesystems without symbolic links support did not
+  work well.
+
+* In-tree documentations and test scripts now use "git foo" form to set a
+  better example, instead of the "git-foo" form (which is an acceptable
+  form if you have "PATH=$(git --exec-path):$PATH" in your script)
+
+* Many commands did not use the correct working tree location when used
+  with GIT_WORK_TREE environment settings.
+
+* Some systems need to use compatibility fnmatch and regex libraries
+  independent from each other; the compat/ area has been reorganized to
+  allow this.
+
+
+* "git apply --unidiff-zero" incorrectly applied a -U0 patch that inserts
+  a new line before the second line.
+
+* "git blame -c" did not exactly work like "git annotate" when range
+  boundaries are involved.
+
+* "git checkout file" when file is still unmerged checked out contents from
+  a random high order stage, which was confusing.
+
+* "git clone $there $here/" with extra trailing slashes after explicit
+  local directory name $here did not work as expected.
+
+* "git diff" on tracked contents with CRLF line endings did not drive "less"
+  intelligently when showing added or removed lines.
+
+* "git diff --dirstat -M" did not add changes in subdirectories up
+  correctly for renamed paths.
+
+* "git diff --cumulative" did not imply "--dirstat".
+
+* "git for-each-ref refs/heads/" did not work as expected.
+
+* "git gui" allowed users to feed patch without any context to be applied.
+
+* "git gui" botched parsing "diff" output when a line that begins with two
+  dashes and a space gets removed or a line that begins with two pluses
+  and a space gets added.
+
+* "git gui" translation updates and i18n fixes.
+
+* "git index-pack" is more careful against disk corruption while completing
+  a thin pack.
+
+* "git log -i --grep=pattern" did not ignore case; neither "git log -E
+  --grep=pattern" triggered extended regexp.
+
+* "git log --pretty="%ad" --date=short" did not use short format when
+  showing the timestamp.
+
+* "git log --author=author" match incorrectly matched with the
+  timestamp part of "author " line in commit objects.
+
+* "git log -F --author=author" did not work at all.
+
+* Build procedure for "git shell" that used stub versions of some
+  functions and globals was not understood by linkers on some platforms.
+
+* "git stash" was fooled by a stat-dirty but otherwise unmodified paths
+  and refused to work until the user refreshed the index.
+
+* "git svn" was broken on Perl before 5.8 with recent fixes to reduce
+  use of temporary files.
+
+* "git verify-pack -v" did not work correctly when given more than one
+  packfile.
+
+Also contains many documentation updates.

+GIT v1.6.1.3 Release Notes
+==========================
+
+Fixes since v1.6.1.2
+--------------------
+
+* "git diff --binary | git apply" pipeline did not work well when
+  a binary blob is changed to a symbolic link.
+
+* Some combinations of -b/-w/--ignore-space-at-eol to "git diff" did
+  not work as expected.
+
+* "git grep" did not pass the -I (ignore binary) option when
+  calling out an external grep program.
+
+* "git log" and friends include HEAD to the set of starting points
+  when --all is given.  This makes a difference when you are not
+  on any branch.
+
+* "git mv" to move an untracked file to overwrite a tracked
+  contents misbehaved.
+
+* "git merge -s octopus" with many potential merge bases did not
+  work correctly.
+
+* RPM binary package installed the html manpages in a wrong place.
+
+Also includes minor documentation fixes and updates.

+--------------------
+
+* .gitignore learned to handle backslash as a quoting mechanism for

+  This fix was first merged to 1.6.2.1.

+* "git fast-export" produced wrong output with some parents missing from
+  commits, when the history is clock-skewed.
+
+* "git fast-import" sometimes failed to read back objects it just wrote
+  out and aborted, because it failed to flush stale cached data.
+
+* "git-ls-tree" and "git-diff-tree" used a pathspec correctly when
+  deciding to descend into a subdirectory but they did not match the
+  individual paths correctly.  This caused pathspecs "abc/d ab" to match
+  "abc/0" ("abc/d" made them decide to descend into the directory "abc/",
+  and then "ab" incorrectly matched "abc/0" when it shouldn't).
+  This fix was first merged to 1.6.2.3.
+
+* import-zips script (in contrib) did not compute the common directory
+  prefix correctly.
+  This fix was first merged to 1.6.2.2.
+
+* "git init" segfaulted when given an overlong template location via
+  the --template= option.
+  This fix was first merged to 1.6.2.4.
+
+* "git repack" did not error out when necessary object was missing in the
+  repository.
+
+* git-repack (invoked from git-gc) did not work as nicely as it should in
+  a repository that borrows objects from neighbours via alternates
+  mechanism especially when some packs are marked with the ".keep" flag
+  to prevent them from being repacked.
+  This fix was first merged to 1.6.2.3.
+
+Also includes minor documentation fixes and updates.

+GIT v1.6.1 Release Notes
+========================
+
+Updates since v1.6.0
+--------------------
+
+When some commands (e.g. "git log", "git diff") spawn pager internally, we
+used to make the pager the parent process of the git command that produces
+output.  This meant that the exit status of the whole thing comes from the
+pager, not the underlying git command.  We swapped the order of the
+processes around and you will see the exit code from the command from now
+on.
+
+(subsystems)
+
+* gitk can call out to git-gui to view "git blame" output; git-gui in turn
+  can run gitk from its blame view.
+
+* Various git-gui updates including updated translations.
+
+* Various gitweb updates from repo.or.cz installation.
+
+* Updates to emacs bindings.
+
+(portability)
+
+* A few test scripts used nonportable "grep" that did not work well on
+  some platforms, e.g. Solaris.
+
+* Sample pre-auto-gc script has OS X support.
+
+* Makefile has support for (ancient) FreeBSD 4.9.
+
+(performance)
+
+* Many operations that are lstat(3) heavy can be told to pre-execute
+  necessary lstat(3) in parallel before their main operations, which
+  potentially gives much improved performance for cold-cache cases or in
+  environments with weak metadata caching (e.g. NFS).
+
+* The underlying diff machinery to produce textual output has been
+  optimized, which would result in faster "git blame" processing.
+
+* Most of the test scripts (but not the ones that try to run servers)
+  can be run in parallel.
+
+* Bash completion of refnames in a repository with massive number of
+  refs has been optimized.
+
+* Cygwin port uses native stat/lstat implementations when applicable,
+  which leads to improved performance.
+
+* "git push" pays attention to alternate repositories to avoid sending
+  unnecessary objects.
+
+* "git svn" can rebuild an out-of-date rev_map file.
+
+(usability, bells and whistles)
+
+* When you mistype a command name, git helpfully suggests what it guesses
+  you might have meant to say.  help.autocorrect configuration can be set
+  to a non-zero value to accept the suggestion when git can uniquely
+  guess.
+
+* The packfile machinery hopefully is more robust when dealing with
+  corrupt packs if redundant objects involved in the corruption are
+  available elsewhere.
+
+* "git add -N path..." adds the named paths as an empty blob, so that
+  subsequent "git diff" will show a diff as if they are creation events.
+
+* "git add" gained a built-in synonym for people who want to say "stage
+  changes" instead of "add contents to the staging area" which amounts
+  to the same thing.
+
+* "git apply" learned --include=paths option, similar to the existing
+  --exclude=paths option.
+
+* "git bisect" is careful about a user mistake and suggests testing of
+  merge base first when good is not a strict ancestor of bad.
+
+* "git bisect skip" can take a range of commits.
+
+* "git blame" re-encodes the commit metainfo to UTF-8 from i18n.commitEncoding
+  by default.
+
+* "git check-attr --stdin" can check attributes for multiple paths.
+
+* "git checkout --track origin/hack" used to be a syntax error.  It now
+  DWIMs to create a corresponding local branch "hack", i.e. acts as if you
+  said "git checkout --track -b hack origin/hack".
+
+* "git checkout --ours/--theirs" can be used to check out one side of a
+  conflicting merge during conflict resolution.
+
+* "git checkout -m" can be used to recreate the initial conflicted state
+  during conflict resolution.
+
+* "git cherry-pick" can also utilize rerere for conflict resolution.
+
+* "git clone" learned to be verbose with -v
+
+* "git commit --author=$name" can look up author name from existing
+  commits.
+
+* output from "git commit" has been reworded in a more concise and yet
+  more informative way.
+
+* "git count-objects" reports the on-disk footprint for packfiles and
+  their corresponding idx files.
+
+* "git daemon" learned --max-connections=<count> option.
+
+* "git daemon" exports REMOTE_ADDR to record client address, so that
+  spawned programs can act differently on it.
+
+* "git describe --tags" favours closer lightweight tags than farther
+  annotated tags now.
+
+* "git diff" learned to mimic --suppress-blank-empty from GNU diff via a
+  configuration option.
+
+* "git diff" learned to put more sensible hunk headers for Python,
+  HTML and ObjC contents.
+
+* "git diff" learned to vary the a/ vs b/ prefix depending on what are
+  being compared, controlled by diff.mnemonicprefix configuration.
+
+* "git diff" learned --dirstat-by-file to count changed files, not number
+  of lines, when summarizing the global picture.
+
+* "git diff" learned "textconv" filters --- a binary or hard-to-read
+  contents can be munged into human readable form and the difference
+  between the results of the conversion can be viewed (obviously this
+  cannot produce a patch that can be applied, so this is disabled in
+  format-patch among other things).
+
+* "--cached" option to "git diff has an easier to remember synonym "--staged",
+  to ask "what is the difference between the given commit and the
+  contents staged in the index?"
+
+* "git for-each-ref" learned "refname:short" token that gives an
+  unambiguously abbreviated refname.
+
+* Auto-numbering of the subject lines is the default for "git
+  format-patch" now.
+
+* "git grep" learned to accept -z similar to GNU grep.
+
+* "git help" learned to use GIT_MAN_VIEWER environment variable before
+  using "man" program.
+
+* "git imap-send" can optionally talk SSL.
+
+* "git index-pack" is more careful against disk corruption while
+  completing a thin pack.
+
+* "git log --check" and "git log --exit-code" passes their underlying diff
+  status with their exit status code.
+
+* "git log" learned --simplify-merges, a milder variant of --full-history;
+  "gitk --simplify-merges" is easier to view than with --full-history.
+
+* "git log" learned "--source" to show what ref each commit was reached
+  from.
+
+* "git log" also learned "--simplify-by-decoration" to show the
+  birds-eye-view of the topology of the history.
+
+* "git log --pretty=format:" learned "%d" format element that inserts
+  names of tags that point at the commit.
+
+* "git merge --squash" and "git merge --no-ff" into an unborn branch are
+  noticed as user errors.
+
+* "git merge -s $strategy" can use a custom built strategy if you have a
+  command "git-merge-$strategy" on your $PATH.
+
+* "git pull" (and "git fetch") can be told to operate "-v"erbosely or
+  "-q"uietly.
+
+* "git push" can be told to reject deletion of refs with receive.denyDeletes
+  configuration.
+
+* "git rebase" honours pre-rebase hook; use --no-verify to bypass it.
+
+* "git rebase -p" uses interactive rebase machinery now to preserve the merges.
+
+* "git reflog expire branch" can be used in place of "git reflog expire
+  refs/heads/branch".
+
+* "git remote show $remote" lists remote branches one-per-line now.
+
+* "git send-email" can be given revision range instead of files and
+  maildirs on the command line, and automatically runs format-patch to
+  generate patches for the given revision range.
+
+* "git submodule foreach" subcommand allows you to iterate over checked
+  out submodules.
+
+* "git submodule sync" subcommands allows you to update the origin URL
+  recorded in submodule directories from the toplevel .gitmodules file.
+
+* "git svn branch" can create new branches on the other end.
+
+* "gitweb" can use more saner PATH_INFO based URL.
+
+(internal)
+
+* "git hash-object" learned to lie about the path being hashed, so that
+  correct gitattributes processing can be done while hashing contents
+  stored in a temporary file.
+
+* various callers of git-merge-recursive avoid forking it as an external
+  process.
+
+* Git class defined in "Git.pm" can be subclasses a bit more easily.
+
+* We used to link GNU regex library as a compatibility layer for some
+  platforms, but it turns out it is not necessary on most of them.
+
+* Some path handling routines used fixed number of buffers used alternately
+  but depending on the call depth, this arrangement led to hard to track
+  bugs.  This issue is being addressed.
+
+
+Fixes since v1.6.0
+------------------
+
+All of the fixes in v1.6.0.X maintenance series are included in this
+release, unless otherwise noted.
+
+* Porcelains implemented as shell scripts were utterly confused when you
+  entered to a subdirectory of a work tree from sideways, following a
+  symbolic link (this may need to be backported to older releases later).
+
+* Tracking symbolic links would work better on filesystems whose lstat()
+  returns incorrect st_size value for them.
+
+* "git add" and "git update-index" incorrectly allowed adding S/F when S
+  is a tracked symlink that points at a directory D that has a path F in
+  it (we still need to fix a similar nonsense when S is a submodule and F
+  is a path in it).
+
+* "git am" after stopping at a broken patch lost --whitespace, -C, -p and
+  --3way options given from the command line initially.
+
+* "git diff --stdin" used to take two trees on a line and compared them,
+  but we dropped support for such a use case long time ago.  This has
+  been resurrected.
+
+* "git filter-branch" failed to rewrite a tag name with slashes in it.
+
+* "git http-push" did not understand URI scheme other than opaquelocktoken
+  when acquiring a lock from the server (this may need to be backported to
+  older releases later).
+
+* After "git rebase -p" stopped with conflicts while replaying a merge,
+ "git rebase --continue" did not work (may need to be backported to older
+  releases).
+
+* "git revert" records relative to which parent a revert was made when
+  reverting a merge.  Together with new documentation that explains issues
+  around reverting a merge and merging from the updated branch later, this
+  hopefully will reduce user confusion (this may need to be backported to
+  older releases later).
+
+* "git rm --cached" used to allow an empty blob that was added earlier to
+  be removed without --force, even when the file in the work tree has
+  since been modified.
+
+* "git push --tags --all $there" failed with generic usage message without
+  telling saying these two options are incompatible.
+
+* "git log --author/--committer" match used to potentially match the
+  timestamp part, exposing internal implementation detail.  Also these did
+  not work with --fixed-strings match at all.
+
+* "gitweb" did not mark non-ASCII characters imported from external HTML fragments
+  correctly.

+GIT v1.6.4.3 Release Notes
+==========================
+
+Fixes since v1.6.4.2
+--------------------
+
+* "git clone" from an empty repository gave unnecessary error message,
+  even though it did everything else correctly.
+
+* "git cvsserver" invoked git commands via "git-foo" style, which has long
+  been deprecated.
+
+* "git fetch" and "git clone" had an extra sanity check to verify the
+  presence of the corresponding *.pack file before downloading *.idx
+  file by issuing a HEAD request.  Github server however sometimes
+  gave 500 (Internal server error) response to HEAD even if a GET
+  request for *.pack file to the same URL would have succeeded, and broke
+  clone over HTTP from some of their repositories.  As a workaround, this
+  verification has been removed (as it is not absolutely necessary).
+
+* "git grep" did not like relative pathname to refer outside the current
+  directory when run from a subdirectory.
+
+* an error message from "git push" was formatted in a very ugly way.
+
+* "git svn" did not quote the subversion user name correctly when
+  running its author-prog helper program.
+
+Other minor documentation updates are included.

+
+ * "git cvsimport" did not read files given as command line arguments

+
+ * "git diff --color-words -U0" didn't work correctly.
+
+ * The handling of blank lines at the end of file by "git diff/apply
+   --whitespace" was inconsistent with the other kinds of errors.
+   They are now colored, warned against, and fixed the same way as others.
+
+ * There was no way to allow blank lines at the end of file without
+   allowing extra blanks at the end of lines.  You can use blank-at-eof
+   and blank-at-eol whitespace error class to specify them separately.
+   The old trailing-space error class is now a short-hand to set both.
+

+
+ * "git imap-send" did not compile cleanly with newer OpenSSL.
+
+ * "git help -a" outside of a git repository was broken.
+
+ * "git ls-files -i" was supposed to be inverse of "git ls-files" without -i
+   with respect to exclude patterns, but it was broken since 1.6.5.2.
+
+ * "git ls-remote" outside of a git repository over http was broken.
+
+ * "git rebase -i" gave bogus error message when the command word was
+   misspelled.
+
+ * "git receive-pack" that is run in response to "git push" did not run

+   command now runs "gc --auto" and "u-s-i" by setting receive.autogc
+   and receive.updateserverinfo configuration variables, respectively.
+
+ * Release notes spelled the package name with incorrect capitalization.
+
+ * "gitweb" did not escape non-ascii characters correctly in the URL.
+
+ * "gitweb" showed "patch" link even for merge commits.

+
+ * "git merge foo HEAD" was misparsed as an old-style invocation of the

+   remove the old style "git merge <message> HEAD <commit>..."  syntax in
+   future versions, but not in this release,
+
+ * "git merge -m <message> <branch>..." added the standard merge message
+   on its own after user-supplied message, which should have overridden the
+   standard one.
+

+Git v1.6.5.5 Release Notes
+==========================
+
+Fixes since v1.6.5.4
+--------------------
+
+ * Manual pages can be formatted with older xmlto again.
+
+ * GREP_OPTIONS exported from user's environment could have broken
+   our scripted commands.
+
+ * In configuration files, a few variables that name paths can begin with
+   ~/ and ~username/ and they are expanded as expected.  This is not a
+   bugfix but 1.6.6 will have this and without backporting users cannot
+   easily use the same ~/.gitconfig across versions.
+
+ * "git diff -B -M" did the same computation to hash lines of contents
+   twice, and held onto memory after it has used the data in it
+   unnecessarily before it freed.
+
+ * "git diff -B" and "git diff --dirstat" was not counting newly added
+   contents correctly.
+
+ * "git format-patch revisions... -- path" issued an incorrect error
+   message that suggested to use "--" on the command line when path
+   does not exist in the current work tree (it is a separate matter if
+   it makes sense to limit format-patch with pathspecs like that
+   without using the --full-diff option).
+
+ * "git grep -F -i StRiNg" did not work as expected.
+
+ * Enumeration of available merge strategies iterated over the list of
+   commands in a wrong way, sometimes producing an incorrect result.
+
+ * "git shortlog" did not honor the "encoding" header embedded in the
+   commit object like "git log" did.
+
+ * Reading progress messages that come from the remote side while running
+   "git pull" is given precedence over reading the actual pack data to
+   prevent garbled progress message on the user's terminal.
+
+ * "git rebase" got confused when the log message began with certain
+   strings that looked like Subject:, Date: or From: header.
+
+ * "git reset" accidentally run in .git/ directory checked out the
+   work tree contents in there.
+
+
+Other minor documentation updates are included.

+Git v1.6.5.6 Release Notes
+==========================
+
+Fixes since v1.6.5.5
+--------------------
+
+ * "git add -p" had a regression since v1.6.5.3 that broke deletion of
+   non-empty files.
+
+ * "git archive -o o.zip -- Makefile" produced an archive in o.zip
+   but in POSIX tar format.
+
+ * Error message given to "git pull --rebase" when the user didn't give
+   enough clue as to what branch to integrate with still talked about
+   "merging with" the branch.
+
+ * Error messages given by "git merge" when the merge resulted in a
+   fast-forward still were in plumbing lingo, even though in v1.6.5
+   we reworded messages in other cases.
+
+ * The post-upload-hook run by upload-pack in response to "git fetch" has
+   been removed, due to security concerns (the hook first appeared in
+   1.6.5).

+Git v1.6.5.7 Release Notes
+==========================
+
+Fixes since v1.6.5.6
+--------------------
+
+* If a user specifies a color for a <slot> (i.e. a class of things to show
+  in a particular color) that is known only by newer versions of git
+  (e.g. "color.diff.func" was recently added for upcoming 1.6.6 release),
+  an older version of git should just ignore them.  Instead we diagnosed
+  it as an error.
+
+* With help.autocorrect set to non-zero value, the logic to guess typos
+  in the subcommand name misfired and ran a random nonsense command.
+
+* If a command is run with an absolute path as a pathspec inside a bare
+  repository, e.g. "rev-list HEAD -- /home", the code tried to run
+  strlen() on NULL, which is the result of get_git_work_tree(), and
+  segfaulted.

+Git v1.6.6 Release Notes
+========================
+
+Notes on behaviour change
+-------------------------
+
+ * In this release, "git fsck" defaults to "git fsck --full" and
+   checks packfiles, and because of this it will take much longer to
+   complete than before.  If you prefer a quicker check only on loose
+   objects (the old default), you can say "git fsck --no-full".  This
+   has been supported by 1.5.4 and newer versions of git, so it is
+   safe to write it in your script even if you use slightly older git
+   on some of your machines.
+
+Preparing yourselves for compatibility issues in 1.7.0
+------------------------------------------------------
+
+In git 1.7.0, which is planned to be the release after 1.6.6, there will
+be a handful of behaviour changes that will break backward compatibility.
+
+These changes were discussed long time ago and existing behaviours have
+been identified as more problematic to the userbase than keeping them for
+the sake of backward compatibility.
+
+When necessary, a transition strategy for existing users has been designed
+not to force them running around setting configuration variables and
+updating their scripts in order to either keep the traditional behaviour
+or adjust to the new behaviour, on the day their sysadmin decides to install
+the new version of git.  When we switched from "git-foo" to "git foo" in
+1.6.0, even though the change had been advertised and the transition
+guide had been provided for a very long time, the users procrastinated
+during the entire transition period, and ended up panicking on the day
+their sysadmins updated their git installation.  We are trying to avoid
+repeating that unpleasantness in the 1.7.0 release.
+
+For changes decided to be in 1.7.0, commands that will be affected
+have been much louder to strongly discourage such procrastination, and
+they continue to be in this release.  If you have been using recent
+versions of git, you would have seen warnings issued when you used
+features whose behaviour will change, with a clear instruction on how
+to keep the existing behaviour if you want to.  You hopefully are
+already well prepared.
+
+Of course, we have also been giving "this and that will change in
+1.7.0; prepare yourselves" warnings in the release notes and
+announcement messages for the past few releases.  Let's see how well
+users will fare this time.
+
+ * "git push" into a branch that is currently checked out (i.e. pointed by
+   HEAD in a repository that is not bare) will be refused by default.
+
+   Similarly, "git push $there :$killed" to delete the branch $killed
+   in a remote repository $there, when $killed branch is the current
+   branch pointed at by its HEAD, will be refused by default.
+
+   Setting the configuration variables receive.denyCurrentBranch and
+   receive.denyDeleteCurrent to 'ignore' in the receiving repository
+   can be used to override these safety features.  Versions of git
+   since 1.6.2 have issued a loud warning when you tried to do these
+   operations without setting the configuration, so repositories of
+   people who still need to be able to perform such a push should
+   already have been future proofed.
+
+   Please refer to:
+
+   http://git.or.cz/gitwiki/GitFaq#non-bare
+   http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
+
+   for more details on the reason why this change is needed and the
+   transition process that already took place so far.
+
+ * "git send-email" will not make deep threads by default when sending a
+   patch series with more than two messages.  All messages will be sent
+   as a reply to the first message, i.e. cover letter.  Git 1.6.6 (this
+   release) will issue a warning about the upcoming default change, when
+   it uses the traditional "deep threading" behaviour as the built-in
+   default.  To squelch the warning but still use the "deep threading"
+   behaviour, give --chain-reply-to option or set sendemail.chainreplyto
+   to true.
+
+   It has been possible to configure send-email to send "shallow thread"
+   by setting sendemail.chainreplyto configuration variable to false.
+   The only thing 1.7.0 release will do is to change the default when
+   you haven't configured that variable.
+
+ * "git status" will not be "git commit --dry-run".  This change does not
+   affect you if you run the command without pathspec.
+
+   Nobody sane found the current behaviour of "git status Makefile" useful
+   nor meaningful, and it confused users.  "git commit --dry-run" has been
+   provided as a way to get the current behaviour of this command since
+   1.6.5.
+
+ * "git diff" traditionally treated various "ignore whitespace" options
+   only as a way to filter the patch output.  "git diff --exit-code -b"
+   exited with non-zero status even if all changes were about changing the
+   amount of whitespace and nothing else.  and "git diff -b" showed the
+   "diff --git" header line for such a change without patch text.
+
+   In 1.7.0, the "ignore whitespaces" will affect the semantics of the
+   diff operation itself.  A change that does not affect anything but
+   whitespaces will be reported with zero exit status when run with
+   --exit-code, and there will not be "diff --git" header for such a
+   change.
+
+
+Updates since v1.6.5
+--------------------
+
+(subsystems)
+
+ * various gitk updates including use of themed widgets under Tk 8.5,
+   Japanese translation, a fix to a bug when running "gui blame" from
+   a subdirectory, etc.
+
+ * various git-gui updates including new translations, wm states fixes,
+   Tk bug workaround after quitting, improved heuristics to trigger gc,
+   etc.
+
+ * various git-svn updates.
+
+ * "git fetch" over http learned a new mode that is different from the
+   traditional "dumb commit walker".
+
+(portability)
+
+ * imap-send can be built on mingw port.
+
+(performance)
+
+ * "git diff -B" has smaller memory footprint.
+
+(usability, bells and whistles)
+
+ * The object replace mechanism can be bypassed with --no-replace-objects
+   global option given to the "git" program.
+
+ * In configuration files, a few variables that name paths can begin with ~/
+   and ~username/ and they are expanded as expected.
+
+ * "git subcmd -h" now shows short usage help for many more subcommands.
+
+ * "git bisect reset" can reset to an arbitrary commit.
+
+ * "git checkout frotz" when there is no local branch "frotz" but there
+   is only one remote tracking branch "frotz" is taken as a request to
+   start the named branch at the corresponding remote tracking branch.
+
+ * "git commit -c/-C/--amend" can be told with a new "--reset-author" option
+   to ignore authorship information in the commit it is taking the message
+   from.
+
+ * "git describe" can be told to add "-dirty" suffix with "--dirty" option.
+
+ * "git diff" learned --submodule option to show a list of one-line logs
+   instead of differences between the commit object names.
+
+ * "git diff" learned to honor diff.color.func configuration to paint
+   function name hint printed on the hunk header "@@ -j,k +l,m @@" line
+   in the specified color.
+
+ * "git fetch" learned --all and --multiple options, to run fetch from
+   many repositories, and --prune option to remove remote tracking
+   branches that went stale.  These make "git remote update" and "git
+   remote prune" less necessary (there is no plan to remove "remote
+   update" nor "remote prune", though).
+
+ * "git fsck" by default checks the packfiles (i.e. "--full" is the
+   default); you can turn it off with "git fsck --no-full".
+
+ * "git grep" can use -F (fixed strings) and -i (ignore case) together.
+
+ * import-tars contributed fast-import frontend learned more types of
+   compressed tarballs.
+
+ * "git instaweb" knows how to talk with mod_cgid to apache2.
+
+ * "git log --decorate" shows the location of HEAD as well.
+
+ * "git log" and "git rev-list" learned to take revs and pathspecs from
+   the standard input with the new "--stdin" option.
+
+ * "--pretty=format" option to "log" family of commands learned:
+
+   . to wrap text with the "%w()" specifier.
+   . to show reflog information with "%g[sdD]" specifier.
+
+ * "git notes" command to annotate existing commits.
+
+ * "git merge" (and "git pull") learned --ff-only option to make it fail
+   if the merge does not result in a fast-forward.
+
+ * "git mergetool" learned to use p4merge.
+
+ * "git rebase -i" learned "reword" that acts like "edit" but immediately
+   starts an editor to tweak the log message without returning control to
+   the shell, which is done by "edit" to give an opportunity to tweak the
+   contents.
+
+ * "git send-email" can be told with "--envelope-sender=auto" to use the
+   same address as "From:" address as the envelope sender address.
+
+ * "git send-email" will issue a warning when it defaults to the
+   --chain-reply-to behaviour without being told by the user and
+   instructs to prepare for the change of the default in 1.7.0 release.
+
+ * In "git submodule add <repository> <path>", <path> is now optional and
+   inferred from <repository> the same way "git clone <repository>" does.
+
+ * "git svn" learned to read SVN 1.5+ and SVK merge tickets.
+
+ * "git svn" learned to recreate empty directories tracked only by SVN.
+
+ * "gitweb" can optionally render its "blame" output incrementally (this
+   requires JavaScript on the client side).
+
+ * Author names shown in gitweb output are links to search commits by the
+   author.
+
+Fixes since v1.6.5
+------------------
+
+All of the fixes in v1.6.5.X maintenance series are included in this
+release, unless otherwise noted.

+
+ * "git show :no-such-name" tried to access the index without bounds
+   check, leading to a potential segfault.
+
+ * Message from "git cherry-pick" was harder to read and use than necessary
+   when it stopped due to conflicting changes.
+
+ * We referred to ".git/refs/" throughout the documentation when we
+   meant to talk about abstract notion of "ref namespace".  Because
+   people's repositories often have packed refs these days, this was
+   confusing.
+
+ * "git diff --output=/path/that/cannot/be/written" did not correctly
+   error out.
+
+ * "git grep -e -pattern-that-begin-with-dash paths..." could not be
+   spelled as "git grep -- -pattern-that-begin-with-dash paths..." which
+   would be a GNU way to use "--" as "end of options".
+
+ * "git grep" compiled with threading support tried to access an
+   uninitialized mutex on boxes with a single CPU.
+
+ * "git stash pop -q --index" failed because the unnecessary --index
+   option was propagated to "git stash drop" that is internally run at the
+   end.
+
+And other minor fixes and documentation updates.

+
+ * updating working tree files after telling git to add them to the

+   the repository without diagnosing it as an error.
+
+ * "git bisect -- pathspec..." did not diagnose an error condition properly when

+
+ * "git rev-list --cherry-pick A...B" now has an obvious optimization when the
+   histories haven't diverged (i.e. when one end is an ancestor of the other).
+
+ * "git diff --quiet -w" did not work as expected.
+
+ * "git fast-import" didn't work with a large input, as it lacked support
+   for producing the pack index in v2 format.
+
+ * "git imap-send" didn't use CRLF line endings over the imap protocol
+   when storing its payload to the draft box, violating RFC 3501.
+
+ * "git log --format='%w(x,y,z)%b'" and friends that rewrap message
+   has been optimized for utf-8 payload.
+
+ * Error messages generated on the receiving end did not come back to "git
+   push".

+ * Object files are created in a more ACL friendly way in repositories
+   where group permission is ACL controlled.
+
+ * "git add -i" didn't handle a deleted path very well.
+
+ * "git blame" padded line numbers with one extra SP when the total number
+   of lines was one less than multiple of ten due to an off-by-one error.
+
+ * "git fetch --all/--multi" used to discard information for remotes that
+   are fetched earlier.
+
+ * "git log --author=me --grep=it" tried to find commits that have "it"
+   or are written by "me", instead of the ones that have "it" _and_ are
+   written by "me".
+
+ * "git log -g branch" misbehaved when there was no entries in the reflog
+   for the named branch.
+
+ * "git mailinfo" (hence "git am") incorrectly removed initial indent from
+   paragraphs.
+
+ * "git prune" and "git reflog" (hence "git gc" as well) didn't honor
+   an instruction never to expire by setting gc.reflogexpire to never.
+
+ * "git push" misbehaved when branch.<name>.merge was configured without
+   matching branch.<name>.remote.
+
+And other minor fixes and documentation updates.

+Git v1.7.0 Release Notes
+========================
+
+Notes on behaviour change
+-------------------------
+
+ * "git push" into a branch that is currently checked out (i.e. pointed at by
+   HEAD in a repository that is not bare) is refused by default.
+
+   Similarly, "git push $there :$killed" to delete the branch $killed
+   in a remote repository $there, when $killed branch is the current
+   branch pointed at by its HEAD, will be refused by default.
+
+   Setting the configuration variables receive.denyCurrentBranch and
+   receive.denyDeleteCurrent to 'ignore' in the receiving repository
+   can be used to override these safety features.
+
+ * "git send-email" does not make deep threads by default when sending a
+   patch series with more than two messages.  All messages will be sent
+   as a reply to the first message, i.e. cover letter.
+
+   It has been possible already to configure send-email to send "shallow thread"
+   by setting sendemail.chainreplyto configuration variable to false.  The
+   only thing this release does is to change the default when you haven't
+   configured that variable.
+
+ * "git status" is not "git commit --dry-run" anymore.  This change does
+   not affect you if you run the command without argument.
+
+ * "git diff" traditionally treated various "ignore whitespace" options
+   only as a way to filter the patch output.  "git diff --exit-code -b"
+   exited with non-zero status even if all changes were about changing the
+   amount of whitespace and nothing else;  and "git diff -b" showed the
+   "diff --git" header line for such a change without patch text.
+
+   In this release, the "ignore whitespaces" options affect the semantics
+   of the diff operation.  A change that does not affect anything but
+   whitespaces is reported with zero exit status when run with
+   --exit-code, and there is no "diff --git" header for such a change.
+
+ * External diff and textconv helpers are now executed using the shell.
+   This makes them consistent with other programs executed by git, and
+   allows you to pass command-line parameters to the helpers. Any helper
+   paths containing spaces or other metacharacters now need to be
+   shell-quoted.  The affected helpers are GIT_EXTERNAL_DIFF in the
+   environment, and diff.*.command and diff.*.textconv in the config
+   file.
+
+ * The --max-pack-size argument to 'git repack', 'git pack-objects', and
+   'git fast-import' was assuming the provided size to be expressed in MiB,
+   unlike the corresponding config variable and other similar options accepting
+   a size value.  It is now expecting a size expressed in bytes, with a possible
+   unit suffix of 'k', 'm', or 'g'.
+
+Updates since v1.6.6
+--------------------
+
+(subsystems)
+
+ * "git fast-import" updates; adds "option" and "feature" to detect the
+   mismatch between fast-import and the frontends that produce the input
+   stream.
+
+ * "git svn" support of subversion "merge tickets" and miscellaneous fixes.
+
+ * "gitk" and "git gui" translation updates.
+
+ * "gitweb" updates (code clean-up, load checking etc.)
+
+(portability)
+
+ * Some more MSVC portability patches for msysgit port.
+
+ * Minimum Pthreads emulation for msysgit port.
+
+(performance)
+
+ * More performance improvement patches for msysgit port.
+
+(usability, bells and whistles)
+
+ * More commands learned "--quiet" and "--[no-]progress" options.
+
+ * Various commands given by the end user (e.g. diff.type.textconv,
+   and GIT_EDITOR) can be specified with command line arguments.  E.g. it
+   is now possible to say "[diff "utf8doc"] textconv = nkf -w".
+
+ * "sparse checkout" feature allows only part of the work tree to be
+   checked out.
+
+ * HTTP transfer can use authentication scheme other than basic
+   (i.e./e.g. digest).
+
+ * Switching from a version of superproject that used to have a submodule
+   to another version of superproject that no longer has it did not remove
+   the submodule directory when it should (namely, when you are not
+   interested in the submodule at all and didn't clone/checkout).
+
+ * A new attribute conflict-marker-size can be used to change the size of
+   the conflict markers from the default 7; this is useful when tracked
+   contents (e.g. git-merge documentation) have strings that resemble the
+   conflict markers.
+
+ * A new syntax "<branch>@{upstream}" can be used on the command line to
+   substitute the name of the "upstream" of the branch.  Missing branch
+   defaults to the current branch, so "git fetch && git merge @{upstream}"
+   will be equivalent to "git pull".
+
+ * "git am --resolved" has a synonym "git am --continue".
+
+ * "git branch --set-upstream" can be used to update the (surprise!) upstream,
+   i.e. where the branch is supposed to pull and merge from (or rebase onto).
+
+ * "git checkout A...B" is a way to detach HEAD at the merge base between
+   A and B.
+
+ * "git checkout -m path" to reset the work tree file back into the
+   conflicted state works even when you already ran "git add path" and
+   resolved the conflicts.
+
+ * "git commit --date='<date>'" can be used to override the author date
+   just like "git commit --author='<name> <email>'" can be used to
+   override the author identity.
+
+ * "git commit --no-status" can be used to omit the listing of the index
+   and the work tree status in the editor used to prepare the log message.
+
+ * "git commit" warns a bit more aggressively until you configure user.email,
+   whose default value almost always is not (and fundamentally cannot be)
+   what you want.
+
+ * "git difftool" has been extended to make it easier to integrate it
+   with gitk.
+
+ * "git fetch --all" can now be used in place of "git remote update".
+
+ * "git grep" does not rely on external grep anymore.  It can use more than
+   one thread to accelerate the operation.
+
+ * "git grep" learned "--quiet" option.
+
+ * "git log" and friends learned "--glob=heads/*" syntax that is a more
+   flexible way to complement "--branches/--tags/--remotes".
+
+ * "git merge" learned to pass options specific to strategy-backends.  E.g.
+
+    - "git merge -Xsubtree=path/to/directory" can be used to tell the subtree
+      strategy how much to shift the trees explicitly.
+
+    - "git merge -Xtheirs" can be used to auto-merge as much as possible,
+      while discarding your own changes and taking merged version in
+      conflicted regions.
+
+ * "git push" learned "git push origin --delete branch", a syntactic sugar
+   for "git push origin :branch".
+
+ * "git push" learned "git push --set-upstream origin forker:forkee" that
+   lets you configure your "forker" branch to later pull from "forkee"
+   branch at "origin".
+
+ * "git rebase --onto A...B" means the history is replayed on top of the
+   merge base between A and B.
+
+ * "git rebase -i" learned new action "fixup" that squashes the change
+   but does not affect existing log message.
+
+ * "git rebase -i" also learned --autosquash option that is useful
+   together with the new "fixup" action.
+
+ * "git remote" learned set-url subcommand that updates (surprise!) url
+   for an existing remote nickname.
+
+ * "git rerere" learned "forget path" subcommand.  Together with "git
+   checkout -m path" it will be useful when you recorded a wrong
+   resolution.
+
+ * Use of "git reset --merge" has become easier when resetting away a
+   conflicted mess left in the work tree.
+
+ * "git rerere" had rerere.autoupdate configuration but there was no way
+   to countermand it from the command line; --no-rerere-autoupdate option
+   given to "merge", "revert", etc. fixes this.
+
+ * "git status" learned "-s(hort)" output format.
+
+(developers)
+
+ * The infrastructure to build foreign SCM interface has been updated.
+
+ * Many more commands are now built-in.
+
+ * THREADED_DELTA_SEARCH is no more.  If you build with threads, delta
+   compression will always take advantage of it.
+
+Fixes since v1.6.6
+------------------
+
+All of the fixes in v1.6.6.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git branch -d branch" used to refuse deleting the branch even when
+   the branch is fully merged to its upstream branch if it is not merged
+   to the current branch.  It now deletes it in such a case.
+
+ * "filter-branch" command incorrectly said --prune-empty and --filter-commit
+   were incompatible; the latter should be read as --commit-filter.
+
+ * When using "git status" or asking "git diff" to compare the work tree
+   with something, they used to consider that a checked-out submodule with
+   uncommitted changes is not modified; this could cause people to forget
+   committing these changes in the submodule before committing in the
+   superproject. They now consider such a change as a modification and
+   "git diff" will append a "-dirty" to the work tree side when generating
+   patch output or when used with the --submodule option.

+Git v1.7.1.1 Release Notes
+==========================
+
+Fixes since v1.7.1
+------------------
+
+ * Authentication over http transport can now be made lazily, in that the
+   request can first go to a URL without username, get a 401 response and
+   then the client will ask for the username to use.
+
+ * We used to mistakenly think "../work" is a subdirectory of the current
+   directory when we are in "../work-xyz".
+
+ * The attribute mechanism now allows an entry that uses an attribute
+   macro that set/unset one attribute, immediately followed by an
+   overriding setting; this makes attribute macros much easier to use.
+
+ * We didn't recognize timezone "Z" as a synonym for "UTC" (75b37e70).
+
+ * In 1.7.0, read-tree and user commands that use the mechanism such as
+   checkout and merge were fixed to handle switching between branches one
+   of which has a file while the other has a directory at the same path
+   correctly even when there are some "confusing" pathnames in them.  But
+   the algorithm used for this fix was suboptimal and had a terrible
+   performance degradation especially in larger trees.
+
+ * "git am -3" did not show diagnosis when the patch in the message was corrupt.
+
+ * After "git apply --whitespace=fix" removed trailing blank lines in an
+   patch in a patch series, it failed to apply later patches that depend
+   on the presence of such blank lines.
+
+ * "git bundle --stdin" segfaulted.
+
+ * "git checkout" and "git rebase" overwrote paths that are marked "assume
+   unchanged".
+
+ * "git commit --amend" on a commit with an invalid author-name line that
+   lacks the display name didn't work.
+
+ * "git describe" did not tie-break tags that point at the same commit
+   correctly; newer ones are preferred by paying attention to the
+   tagger date now.
+
+ * "git diff" used to tell underlying xdiff machinery to work very hard to
+   minimize the output, but this often was spending too many extra cycles
+   for very little gain.
+
+ * "git diff --color" did not paint extended diff headers per line
+   (i.e. the coloring escape sequence didn't end at the end of line),
+   which confused "less -R".
+
+ * "git fetch" over HTTP verifies the downloaded packfiles more robustly.
+
+ * The memory usage by "git index-pack" (run during "git fetch" and "git
+   push") got leaner.
+
+ * "GIT_DIR=foo.git git init --bare bar.git" created foo.git instead of bar.git.
+
+ * "git log --abbrev=$num --format='%h' ignored --abbrev=$num.
+
+ * "git ls-files ../out/side/cwd" refused to work.
+
+ * "git merge --log" used to replace the custom message given by "-m" with
+   the shortlog, instead of appending to it.
+
+ * "git notes copy" without any other argument segfaulted.
+
+ * "git pull" accepted "--dry-run", gave it to underlying "git fetch" but
+   ignored the option itself, resulting in a bogus attempt to merge
+   unrelated commit.
+
+ * "git rebase" did not faithfully reproduce a malformed author ident, that
+   is often seen in a repository converted from foreign SCMs.
+
+ * "git reset --hard" started from a wrong directory and a working tree in
+   a nonstandard location is in use got confused.
+
+ * "git send-email" lacked a way to specify the domainname used in the
+   EHLO/HELO exchange, causing rejected connection from picky servers.
+   It learned --smtp-domain option to solve this issue.
+
+ * "git send-email" did not declare a content-transfer-encoding and
+   content-type even when its payload needs to be sent in 8-bit.
+
+ * "git show -C -C" and other corner cases lost diff metainfo output
+   in 1.7.0.
+
+ * "git stash" incorrectly lost paths in the working tree that were
+   previously removed from the index.
+
+ * "git status" stopped refreshing the index by mistake in 1.7.1.
+
+ * "git status" showed excess "hints" even when advice.statusHints is set to false.
+
+And other minor fixes and documentation updates.

+
+ * "git clone/fetch/pull" issued an incorrect error message when a ref and

+Git v1.7.1 Release Notes
+========================
+
+Updates since v1.7.0
+--------------------
+
+ * Eric Raymond is the maintainer of updated CIAbot scripts, in contrib/.
+
+ * gitk updates.
+
+ * Some commands (e.g. svn and http interfaces) that interactively ask
+   for a password can be told to use an external program given via
+   GIT_ASKPASS.
+
+ * Conflict markers that lead the common ancestor in diff3-style output
+   now have a label, which hopefully would help third-party tools that
+   expect one.
+
+ * Comes with an updated bash-completion script.
+
+ * "git am" learned "--keep-cr" option to handle inputs that are
+   a mixture of changes to files with and without CRLF line endings.
+
+ * "git cvsimport" learned -R option to leave revision mapping between
+   CVS revisions and resulting git commits.
+
+ * "git diff --submodule" notices and describes dirty submodules.
+
+ * "git for-each-ref" learned %(symref), %(symref:short) and %(flag)
+   tokens.
+
+ * "git hash-object --stdin-paths" can take "--no-filters" option now.
+
+ * "git init" can be told to look at init.templatedir configuration
+   variable (obviously that has to come from either /etc/gitconfig or
+   $HOME/.gitconfig).
+
+ * "git grep" learned "--no-index" option, to search inside contents that
+   are not managed by git.
+
+ * "git grep" learned --color=auto/always/never.
+
+ * "git grep" learned to paint filename and line-number in colors.
+
+ * "git log -p --first-parent -m" shows one-parent diff for merge
+   commits, instead of showing combined diff.
+
+ * "git merge-file" learned to use custom conflict marker size and also
+   to use the "union merge" behaviour.
+
+ * "git notes" command has been rewritten in C and learned many commands
+   and features to help you carry notes forward across rebases and amends.
+
+ * "git request-pull" identifies the commit the request is relative to in
+   a more readable way.
+
+ * "git reset" learned "--keep" option that lets you discard commits
+   near the tip while preserving your local changes in a way similar
+   to how "git checkout branch" does.
+
+ * "git status" notices and describes dirty submodules.
+
+ * "git svn" should work better when interacting with repositories
+   with CRLF line endings.
+
+ * "git imap-send" learned to support CRAM-MD5 authentication.
+
+ * "gitweb" installation procedure can use "minified" js/css files

+All of the fixes in v1.7.0.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git add frotz/nitfol" did not complain when the entire frotz/ directory
+   was ignored.
+
+ * "git diff --stat" used "int" to count the size of differences,
+   which could result in overflowing.
+
+ * "git rev-list --pretty=oneline" didn't terminate a record with LF for
+   commits without any message.
+
+ * "git rev-list --abbrev-commit" defaulted to 40-byte abbreviations, unlike
+   newer tools in the git toolset.

+Git v1.7.10.1 Release Notes
+===========================
+
+Additions since v1.7.10
+-----------------------
+
+Localization message files for Danish and German have been added.
+
+
+Fixes since v1.7.10
+-------------------
+
+ * "git add -p" is not designed to deal with unmerged paths but did
+   not exclude them and tried to apply funny patches only to fail.
+
+ * "git blame" started missing quite a few changes from the origin
+   since we stopped using the diff minimization by default in v1.7.2
+   era.
+
+ * When PATH contains an unreadable directory, alias expansion code
+   did not kick in, and failed with an error that said "git-subcmd"
+   was not found.
+
+ * "git clean -d -f" (not "-d -f -f") is supposed to protect nested
+   working trees of independent git repositories that exist in the
+   current project working tree from getting removed, but the
+   protection applied only to such working trees that are at the
+   top-level of the current project by mistake.
+
+ * "git commit --author=$name" did not tell the name that was being
+   recorded in the resulting commit to hooks, even though it does do
+   so when the end user overrode the authorship via the
+   "GIT_AUTHOR_NAME" environment variable.
+
+ * When "git commit --template F" errors out because the user did not
+   touch the message, it claimed that it aborts due to "empty
+   message", which was utterly wrong.
+
+ * The regexp configured with diff.wordregex was incorrectly reused
+   across files.
+
+ * An age-old corner case bug in combine diff (only triggered with -U0
+   and the hunk at the beginning of the file needs to be shown) has
+   been fixed.
+
+ * Rename detection logic used to match two empty files as renames
+   during merge-recursive, leading to unnatural mismerges.
+
+ * The parser in "fast-import" did not diagnose ":9" style references
+   that is not followed by required SP/LF as an error.
+
+ * When "git fetch" encounters repositories with too many references,
+   the command line of "fetch-pack" that is run by a helper
+   e.g. remote-curl, may fail to hold all of them. Now such an
+   internal invocation can feed the references through the standard
+   input of "fetch-pack".
+
+ * "git fetch" that recurses into submodules on demand did not check
+   if it needs to go into submodules when non branches (most notably,
+   tags) are fetched.
+
+ * "log -p --graph" used with "--stat" had a few formatting error.
+
+ * Running "notes merge --commit" failed to perform correctly when run
+   from any directory inside $GIT_DIR/.  When "notes merge" stops with
+   conflicts, $GIT_DIR/NOTES_MERGE_WORKTREE is the place a user edits
+   to resolve it.
+
+ * The 'push to upstream' implementation was broken in some corner
+   cases. "git push $there" without refspec, when the current branch
+   is set to push to a remote different from $there, used to push to
+   $there using the upstream information to a remote unreleated to
+   $there.
+
+ * Giving "--continue" to a conflicted "rebase -i" session skipped a
+   commit that only results in changes to submodules.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.10.2 Release Notes
+===========================
+
+Fixes since v1.7.10.1
+---------------------
+
+ * The test scaffolding for git-daemon was flaky.
+
+ * The test scaffolding for fast-import was flaky.
+
+ * The filesystem boundary was not correctly reported when .git directory
+   discovery stopped at a mount point.
+
+ * HTTP transport that requires authentication did not work correctly when
+   multiple connections are used simultaneously.
+
+ * Minor memory leak during unpack_trees (hence "merge" and "checkout"
+   to check out another branch) has been plugged.
+
+ * In the older days, the header "Conflicts:" in "cherry-pick" and "merge"
+   was separated by a blank line from the list of paths that follow for
+   readability, but when "merge" was rewritten in C, we lost it by
+   mistake. Remove the newline from "cherry-pick" to make them match
+   again.
+
+ * The command line parser choked "git cherry-pick $name" when $name can
+   be both revision name and a pathname, even though $name can never be a
+   path in the context of the command.
+
+ * The "include.path" facility in the configuration mechanism added in
+   1.7.10 forgot to interpret "~/path" and "~user/path" as it should.
+
+ * "git config --rename-section" to rename an existing section into a
+   bogus one did not check the new name.
+
+ * The "diff --no-index" codepath used limited-length buffers, risking
+   pathnames getting truncated.  Update it to use the strbuf API.
+
+ * The report from "git fetch" said "new branch" even for a non branch
+   ref.
+
+ * The http-backend (the server side of the smart http transfer) used
+   to overwrite GIT_COMMITTER_NAME and GIT_COMMITTER_EMAIL with the
+   value obtained from REMOTE_USER unconditionally, making it
+   impossible for the server side site-specific customization to use
+   different identity sources to affect the names logged. It now uses
+   REMOTE_USER only as a fallback value.
+
+ * "log --graph" was not very friendly with "--stat" option and its
+   output had line breaks at wrong places.
+
+ * Octopus merge strategy did not reduce heads that are recorded in the
+   final commit correctly.
+
+ * "git push" over smart-http lost progress output a few releases ago;
+   this release resurrects it.
+
+ * The error and advice messages given by "git push" when it fails due
+   to non-ff were not very helpful to new users; it has been broken
+   into three cases, and each is given a separate advice message.
+
+ * The insn sheet given by "rebase -i" did not make it clear that the
+   insn lines can be re-ordered to affect the order of the commits in
+   the resulting history.
+
+ * "git repack" used to write out unreachable objects as loose objects
+   when repacking, even if such loose objects will immediately pruned
+   due to its age.
+
+ * A contrib script "rerere-train" did not work out of the box unless
+   user futzed with her $PATH.
+
+ * "git rev-parse --show-prefix" used to emit nothing when run at the
+   top-level of the working tree, but now it gives a blank line.
+
+ * The i18n of error message "git stash save" was not properly done.
+
+ * "git submodule" used a sed script that some platforms mishandled.
+
+ * When using a Perl script on a system where "perl" found on user's
+   $PATH could be ancient or otherwise broken, we allow builders to
+   specify the path to a good copy of Perl with $PERL_PATH.  The
+   gitweb test forgot to use that Perl when running its test.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.10.3 Release Notes
+===========================
+
+Fixes since v1.7.10.2
+---------------------
+
+ * The message file for German translation has been updated a bit.
+
+ * Running "git checkout" on an unborn branch used to corrupt HEAD.
+
+ * When checking out another commit from an already detached state, we
+   used to report all commits that are not reachable from any of the
+   refs as lossage, but some of them might be reachable from the new
+   HEAD, and there is no need to warn about them.
+
+ * Some time ago, "git clone" lost the progress output for its
+   "checkout" phase; when run without any "--quiet" option, it should
+   give progress to the lengthy operation.
+
+ * The directory path used in "git diff --no-index", when it recurses
+   down, was broken with a recent update after v1.7.10.1 release.
+
+ * "log -z --pretty=tformat:..." did not terminate each record with
+   NUL.  The fix is not entirely correct when the output also asks for
+   --patch and/or --stat, though.
+
+ * The DWIM behaviour for "log --pretty=format:%gd -g" was somewhat
+   broken and gave undue precedence to configured log.date, causing
+   "git stash list" to show "stash@{time stamp string}".
+
+ * "git status --porcelain" ignored "--branch" option by mistake.  The
+   output for "git status --branch -z" was also incorrect and did not
+   terminate the record for the current branch name with NUL as asked.
+
+ * When a submodule repository uses alternate object store mechanism,
+   some commands that were started from the superproject did not
+   notice it and failed with "No such object" errors.  The subcommands
+   of "git submodule" command that recursed into the submodule in a
+   separate process were OK; only the ones that cheated and peeked
+   directly into the submodule's repository from the primary process
+   were affected.
+
+Also contains minor fixes and documentation updates.

+---------------------

+ * A name taken from mailmap was copied into an internal buffer

+
+ * A malformed commit object that has a header line chomped in the

+
+ * When "git rebase" was given a bad commit to replay the history on,

+Git v1.7.10 Release Notes
+=========================
+
+Compatibility Notes
+-------------------
+
+ * From this release on, the "git merge" command in an interactive
+   session will start an editor when it automatically resolves the
+   merge for the user to explain the resulting commit, just like the
+   "git commit" command does when it wasn't given a commit message.
+
+   If you have a script that runs "git merge" and keeps its standard
+   input and output attached to the user's terminal, and if you do not
+   want the user to explain the resulting merge commits, you can
+   export GIT_MERGE_AUTOEDIT environment variable set to "no", like
+   this:
+
+	#!/bin/sh
+	GIT_MERGE_AUTOEDIT=no
+	export GIT_MERGE_AUTOEDIT
+
+   to disable this behavior (if you want your users to explain their
+   merge commits, you do not have to do anything).  Alternatively, you
+   can give the "--no-edit" option to individual invocations of the
+   "git merge" command if you know everybody who uses your script has
+   Git v1.7.8 or newer.
+
+ * The "--binary/-b" options to "git am" have been a no-op for quite a
+   while and were deprecated in mid 2008 (v1.6.0).  When you give these
+   options to "git am", it will now warn and ask you not to use them.
+
+ * When you do not tell which branches and tags to push to the "git
+   push" command in any way, the command used "matching refs" rule to
+   update remote branches and tags with branches and tags with the
+   same name you locally have.  In future versions of Git, this will
+   change to push out only your current branch according to either the
+   "upstream" or the "current" rule.  Although "upstream" may be more
+   powerful once the user understands Git better, the semantics
+   "current" gives is simpler and easier to understand for beginners
+   and may be a safer and better default option.  We haven't decided
+   yet which one to switch to.
+
+
+Updates since v1.7.9
+--------------------
+
+UI, Workflows & Features
+
+ * various "gitk" updates.
+   - show the path to the top level directory in the window title
+   - update preference edit dialog
+   - display file list correctly when directories are given on command line
+   - make "git-describe" output in the log message into a clickable link
+   - avoid matching the UNIX timestamp part when searching all fields
+   - give preference to symbolic font names like sans & monospace
+   - allow comparing two commits using a mark
+   - "gitk" honors log.showroot configuration.
+
+ * Teams for localizing the messages from the Porcelain layer of
+   commands are starting to form, thanks to Jiang Xin who volunteered
+   to be the localization coordinator.  Translated messages for
+   simplified Chinese, Swedish and Portuguese are available.
+
+ * The configuration mechanism learned an "include" facility; an
+   assignment to the include.path pseudo-variable causes the named
+   file to be included in-place when Git looks up configuration
+   variables.
+
+ * A content filter (clean/smudge) used to be just a way to make the
+   recorded contents "more useful", and allowed to fail; a filter can
+   now optionally be marked as "required".
+
+ * Options whose names begin with "--no-" (e.g. the "--no-verify"
+   option of the "git commit" command) can be negated by omitting
+   "no-" from its name, e.g. "git commit --verify".
+
+ * "git am" learned to pass "-b" option to underlying "git mailinfo", so
+   that a bracketed string other than "PATCH" at the beginning can be kept.
+
+ * "git clone" learned "--single-branch" option to limit cloning to a
+   single branch (surprise!); tags that do not point into the history
+   of the branch are not fetched.
+
+ * "git clone" learned to detach the HEAD in the resulting repository
+   when the user specifies a tag with "--branch" (e.g., "--branch=v1.0").
+   Clone also learned to print the usual "detached HEAD" advice in such
+   a case, similar to "git checkout v1.0".
+
+ * When showing a patch while ignoring whitespace changes, the context
+   lines are taken from the postimage, in order to make it easier to
+   view the output.
+
+ * "git diff --stat" learned to adjust the width of the output on
+   wider terminals, and give more columns to pathnames as needed.
+
+ * "diff-highlight" filter (in contrib/) was updated to produce more
+   aesthetically pleasing output.
+
+ * "fsck" learned "--no-dangling" option to omit dangling object
+   information.
+
+ * "git log -G" and "git log -S" learned to pay attention to the "-i"
+   option.  With "-i", "log -G" ignores the case when finding patch
+   hunks that introduce or remove a string that matches the given
+   pattern.  Similarly with "-i", "log -S" ignores the case when
+   finding the commit the given block of text appears or disappears
+   from the file.
+
+ * "git merge" in an interactive session learned to spawn the editor
+   by default to let the user edit the auto-generated merge message,
+   to encourage people to explain their merges better. Legacy scripts
+   can export GIT_MERGE_AUTOEDIT=no to retain the historical behavior.
+   Both "git merge" and "git pull" can be given --no-edit from the
+   command line to accept the auto-generated merge message.
+
+ * The advice message given when the user didn't give enough clue on
+   what to merge to "git pull" and "git merge" has been updated to
+   be more concise and easier to understand.
+
+ * "git push" learned the "--prune" option, similar to "git fetch".
+
+ * The whole directory that houses a top-level superproject managed by
+   "git submodule" can be moved to another place.
+
+ * "git symbolic-ref" learned the "--short" option to abbreviate the
+   refname it shows unambiguously.
+
+ * "git tag --list" can be given "--points-at <object>" to limit its
+   output to those that point at the given object.
+
+ * "gitweb" allows intermediate entries in the directory hierarchy
+   that leads to a project to be clicked, which in turn shows the
+   list of projects inside that directory.
+
+ * "gitweb" learned to read various pieces of information for the
+   repositories lazily, instead of reading everything that could be
+   needed (including the ones that are not necessary for a specific
+   task).
+
+ * Project search in "gitweb" shows the substring that matched in the
+   project name and description highlighted.
+
+ * HTTP transport learned to authenticate with a proxy if needed.
+
+ * A new script "diffall" is added to contrib/; it drives an
+   external tool to perform a directory diff of two Git revisions
+   in one go, unlike "difftool" that compares one file at a time.
+
+Foreign Interface
+
+ * Improved handling of views, labels and branches in "git-p4" (in contrib).
+
+ * "git-p4" (in contrib) suffered from unnecessary merge conflicts when
+   p4 expanded the embedded $RCS$-like keywords; it can be now told to
+   unexpand them.
+
+ * Some "git-svn" updates.
+
+ * "vcs-svn"/"svn-fe" learned to read dumps with svn-deltas and
+   support incremental imports.
+
+ * "git difftool/mergetool" learned to drive DeltaWalker.
+
+Performance
+
+ * Unnecessary calls to parse_object() "git upload-pack" makes in
+   response to "git fetch", have been eliminated, to help performance
+   in repositories with excessive number of refs.
+
+Internal Implementation (please report possible regressions)
+
+ * Recursive call chains in "git index-pack" to deal with long delta
+   chains have been flattened, to reduce the stack footprint.
+
+ * Use of add_extra_ref() API is now gone, to make it possible to
+   cleanly restructure the overall refs API.
+
+ * The command line parser of "git pack-objects" now uses parse-options
+   API.
+
+ * The test suite supports the new "test_pause" helper function.
+
+ * Parallel to the test suite, there is a beginning of performance
+   benchmarking framework.
+
+ * t/Makefile is adjusted to prevent newer versions of GNU make from
+   running tests in seemingly random order.
+
+ * The code to check if a path points at a file beyond a symbolic link
+   has been restructured to be thread-safe.
+
+ * When pruning directories that has become empty during "git prune"
+   and "git prune-packed", call closedir() that iterates over a
+   directory before rmdir() it.
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.7.9
+------------------
+
+Unless otherwise noted, all the fixes since v1.7.9 in the maintenance
+releases are contained in this release (see release notes to them for
+details).
+
+ * Build with NO_PERL_MAKEMAKER was broken and Git::I18N did not work
+   with versions of Perl older than 5.8.3.
+   (merge 5eb660e ab/perl-i18n later to maint).
+
+ * "git tag -s" honored "gpg.program" configuration variable since
+   1.7.9, but "git tag -v" and "git verify-tag" didn't.
+   (merge a2c2506 az/verify-tag-use-gpg-config later to maint).
+
+ * "configure" script learned to take "--with-sane-tool-path" from the
+   command line to record SANE_TOOL_PATH (used to avoid broken platform
+   tools in /usr/bin) in config.mak.autogen.  This may be useful for
+   people on Solaris who have saner tools outside /usr/xpg[46]/bin.
+
+ * zsh port of bash completion script needed another workaround.

+Git v1.7.11.2 Release Notes
+===========================
+
+Fixes since v1.7.11.1
+---------------------
+
+ * On Cygwin, the platform pread(2) is not thread safe, just like our
+   own compat/ emulation, and cannot be used in the index-pack
+   program.  Makefile variable NO_THREAD_SAFE_PREAD can be defined to
+   avoid use of this function in a threaded program.
+
+ * "git add" allows adding a regular file to the path where a
+   submodule used to exist, but "git update-index" does not allow an
+   equivalent operation to Porcelain writers.
+
+ * "git archive" incorrectly computed the header checksum; the symptom
+   was observed only when using pathnames with hi-bit set.
+
+ * "git blame" did not try to make sure that the abbreviated commit
+   object names in its output are unique.
+
+ * Running "git bundle verify" on a bundle that records a complete
+   history said "it requires these 0 commits".
+
+ * "git clone --single-branch" to clone a single branch did not limit
+   the cloning to the specified branch.
+
+ * "git diff --no-index" did not correctly handle relative paths and
+   did not correctly give exit codes when run under "--quiet" option.
+
+ * "git diff --no-index" did not work with pagers correctly.
+
+ * "git diff COPYING HEAD:COPYING" gave a nonsense error message that
+   claimed that the tree-ish HEAD did not have COPYING in it.
+
+ * When "git log" gets "--simplify-merges/by-decoration" together with
+   "--first-parent", the combination of these options makes the
+   simplification logic to use in-core commit objects that haven't
+   been examined for relevance, either producing incorrect result or
+   taking too long to produce any output.  Teach the simplification
+   logic to ignore commits that the first-parent traversal logic
+   ignored when both are in effect to work around the issue.
+
+ * "git ls-files --exclude=t -i" did not consider anything under t/ as
+   excluded, as it did not pay attention to exclusion of leading paths
+   while walking the index.  Other two users of excluded() are also
+   updated.
+
+ * "git request-pull $url dev" when the tip of "dev" branch was tagged
+   with "ext4-for-linus" used the contents from the tag in the output
+   but still asked the "dev" branch to be pulled, not the tag.
+
+Also contains minor typofixes and documentation updates.

+   which we don't.
+
+ * A handful of files and directories we create had tighter than

+   message, with or without "--allow-empty-message".
+
+ * "git commit --amend --only --" was meant to allow "Clever" people to
+   rewrite the commit message without making any change even when they
+   have already changes for the next commit added to their index, but
+   it never worked as advertised since it was introduced in 1.3.0 era.
+
+ * Even though the index can record pathnames longer than 1<<12 bytes,
+   in some places we were not comparing them in full, potentially
+   replacing index entries instead of adding.
+
+ * "git show"'s auto-walking behaviour was an unreliable and
+   unpredictable hack; it now behaves just like "git log" does when it
+   walks.
+
+ * "git diff", "git status" and anything that internally uses the
+   comparison machinery was utterly broken when the difference
+   involved a file with "-" as its name.  This was due to the way "git
+   diff --no-index" was incorrectly bolted on to the system, making
+   any comparison that involves a file "-" at the root level
+   incorrectly read from the standard input.
+
+ * We did not have test to make sure "git rebase" without extra options
+   filters out an empty commit in the original history.
+
+ * "git fast-export" produced an input stream for fast-import without
+   properly quoting pathnames when they contain SPs in them.
+
+ * "git checkout --detach", when you are still on an unborn branch,
+   should be forbidden, but it wasn't.
+
+ * Some implementations of Perl terminates "lines" with CRLF even when
+   the script is operating on just a sequence of bytes.  Make sure to
+   use "$PERL_PATH", the version of Perl the user told Git to use, in
+   our tests to avoid unnecessary breakages in tests.
+
+Also contains minor typofixes and documentation updates.

+Git v1.7.11.4 Release Notes
+===========================
+
+Fixes since v1.7.11.3
+---------------------
+
+ * "$GIT_DIR/COMMIT_EDITMSG" file that is used to hold the commit log
+   message user edits was not documented.
+
+ * The advise() function did not use varargs correctly to format
+   its message.
+
+ * When "git am" failed, old timers knew to check .git/rebase-apply/patch
+   to see what went wrong, but we never told the users about it.
+
+ * "git commit-tree" learned a more natural "-p <parent> <tree>" order
+   of arguments long time ago, but recently forgot it by mistake.
+
+ * "git diff --no-ext-diff" did not output anything for a typechange
+   filepair when GIT_EXTERNAL_DIFF is in effect.
+
+ * In 1.7.9 era, we taught "git rebase" about the raw timestamp format
+   but we did not teach the same trick to "filter-branch", which rolled
+   a similar logic on its own.
+
+ * When "git submodule add" clones a submodule repository, it can get
+   confused where to store the resulting submodule repository in the
+   superproject's .git/ directory when there is a symbolic link in the
+   path to the current directory.
+
+Also contains minor typofixes and documentation updates.

+
+ * On some architectures, "block-sha1" did not compile correctly

+
+ * "git checkout <branchname>" to come back from a detached HEAD state

+Git v1.7.11.6 Release Notes
+===========================
+
+Fixes since v1.7.11.5
+---------------------
+
+ * "ciabot" script (in contrib/) has been updated with extensive
+   documentation.
+
+ * "git foo" errored out with "Not a directory" when the user had a
+   non-directory on $PATH, and worse yet it masked an alias "foo" from
+   running.
+
+ * When the user exports a non-default IFS without HT, scripts that
+   rely on being able to parse "ls-files -s | while read a b c..."
+   started to fail.  Protect them from such a misconfiguration.
+
+ * When the user gives an argument that can be taken as both a
+   revision name and a pathname without disambiguating with "--", we
+   used to give a help message "Use '--' to separate".  The message
+   has been clarified to show where that '--' goes on the command
+   line.
+
+ * Documentation for the configuration file format had a confusing
+   example.
+
+ * Older parts of the documentation described as if having a regular
+   file in .git/refs/ hierarchy were the only way to have branches and
+   tags, which is not true for quite some time.
+
+ * It was generally understood that "--long-option"s to many of our
+   subcommands can be abbreviated to the unique prefix, but it was not
+   easy to find it described for new readers of the documentation set.
+
+ * The "--topo-order", "--date-order" (and the lack of either means
+   the default order) options to "rev-list" and "log" family of
+   commands were poorly described in the documentation.
+
+ * "git commit --amend" let the user edit the log message and then
+   died when the human-readable committer name was given
+   insufficiently by getpwent(3).
+
+ * The exit status code from "git config" was way overspecified while
+   being incorrect.  The implementation has been updated to give the
+   documented status for a case that was documented, and introduce a
+   new code for "all other errors".
+
+ * The output from "git diff -B" for a file that ends with an
+   incomplete line did not put "\ No newline..." on a line of its own.
+
+ * "git diff" had a confusion between taking data from a path in the
+   working tree and taking data from an object that happens to have
+   name 0{40} recorded in a tree.
+
+ * The "--rebase" option to "git pull" can be abbreviated to "-r",
+   but we didn't document it.
+
+ * When "git push" triggered the automatic gc on the receiving end, a
+   message from "git prune" that said it was removing cruft leaked to
+   the standard output, breaking the communication protocol.
+
+ * The reflog entries left by "git rebase" and "git rebase -i" were
+   inconsistent (the interactive one gave an abbreviated object name).
+
+ * "git send-email" did not unquote encoded words that appear on the
+   header correctly, and lost "_" from strings.
+
+ * "git stash apply/pop" did not trigger "rerere" upon conflicts
+   unlike other mergy operations.
+
+ * "git submodule <cmd> path" did not error out when the path to the
+   submodule was misspelt.
+
+ * "git submodule update -f" did not update paths in the working tree
+   that has local changes.
+   (merge 01d4721 sz/submodule-force-update later to maint).
+
+ * "gitweb" when used with PATH_INFO failed to notice directories with
+   SP (and other characters that need URL-style quoting) in them.
+
+ * Fallback 'getpass' implementation made unportable use of stdio API.
+
+ * A utility shell function test_seq has been added as a replacement
+   for the 'seq' utility found on some platforms.

+Git v1.7.11.7 Release Notes

+---------------------
+
+ * The synopsis said "checkout [-B branch]" to make it clear the
+   branch name is a parameter to the option, but the heading for the
+   option description was "-B::", not "-B branch::", making the
+   documentation misleading.
+
+ * Git ships with a fall-back regexp implementation for platforms with
+   buggy regexp library, but it was easy for people to keep using their
+   platform regexp.  A new test has been added to check this.
+
+ * "git apply -p0" did not parse pathnames on "diff --git" line
+   correctly.  This caused patches that had pathnames in no other
+   places to be mistakenly rejected (most notably, binary patch that
+   does not rename nor change mode).  Textual patches, renames or mode
+   changes have preimage and postimage pathnames in different places
+   in a form that can be parsed unambiguously and did not suffer from
+   this problem.
+
+ * After "gitk" showed the contents of a tag, neither "Reread
+   references" nor "Reload" did not update what is shown as the
+   contents of it, when the user overwrote the tag with "git tag -f".
+
+ * "git for-each-ref" did not currectly support more than one --sort

+
+ * Pushing to smart HTTP server with recent Git fails without having

+   configured to allow GET anonymously, while requiring authentication
+   for POST.
+
+ * "git show --format='%ci'" did not give timestamp correctly for

+Git v1.7.11 Release Notes
+=========================
+
+Updates since v1.7.10
+---------------------
+
+UI, Workflows & Features
+
+ * A new mode for push, "simple", which is a cross between "current"
+   and "upstream", has been introduced. "git push" without any refspec
+   will push the current branch out to the same name at the remote
+   repository only when it is set to track the branch with the same
+   name over there.  The plan is to make this mode the new default
+   value when push.default is not configured.
+
+ * A couple of commands learned the "--column" option to produce
+   columnar output.
+
+ * A third-party tool "git subtree" is distributed in contrib/
+
+ * A remote helper that acts as a proxy and caches ssl session for the
+   https:// transport is added to the contrib/ area.
+
+ * Error messages given when @{u} is used for a branch without its
+   upstream configured have been clarified.
+
+ * Even with the "-q"uiet option, "checkout" used to report setting up
+   tracking.  Also "branch" learned the "-q"uiet option to squelch
+   informational message.
+
+ * Your build platform may support hardlinks but you may prefer not to
+   use them, e.g. when installing to DESTDIR to make a tarball and
+   untarring on a filesystem that has poor support for hardlinks.
+   There is a Makefile option NO_INSTALL_HARDLINKS for you.
+
+ * The smart-http backend used to always override GIT_COMMITTER_*
+   variables with REMOTE_USER and REMOTE_ADDR, but these variables are
+   now preserved when set.
+
+ * "git am" learned the "--include" option, which is an opposite of
+   existing the "--exclude" option.
+
+ * When "git am -3" needs to fall back to an application of the patch
+   to a synthesized preimage followed by a 3-way merge, the paths that
+   needed such treatment are now reported to the end user, so that the
+   result in them can be eyeballed with extra care.
+
+ * The output from "diff/log --stat" used to always allocate 4 columns
+   to show the number of modified lines, but not anymore.
+
+ * "git difftool" learned the "--dir-diff" option to spawn external
+   diff tools that can compare two directory hierarchies at a time
+   after populating two temporary directories, instead of running an
+   instance of the external tool once per a file pair.
+
+ * The "fmt-merge-msg" command learned to list the primary contributors
+   involved in the side topic you are merging in a comment in the merge
+   commit template.
+
+ * "git rebase" learned to optionally keep commits that do not
+   introduce any change in the original history.
+
+ * "git push --recurse-submodules" learned to optionally look into the
+   histories of submodules bound to the superproject and push them
+   out.
+
+ * A 'snapshot' request to "gitweb" honors If-Modified-Since: header,
+   based on the commit date.
+
+ * "gitweb" learned to highlight the patch it outputs even more.
+
+Foreign Interface
+
+ * "git svn" used to die with unwanted SIGPIPE when talking with an HTTP
+   server that uses keep-alive.
+
+ * "git svn" learned to use platform specific authentication
+   providers, e.g. gnome-keyring, kwallet, etc.
+
+ * "git p4" has been moved out of the contrib/ area and has seen more
+   work on importing labels as tags from (and exporting tags as labels
+   to) p4.
+
+Performance and Internal Implementation (please report possible regressions)
+
+ * Bash completion script (in contrib/) have been cleaned up to make
+   future work on it simpler.
+
+ * An experimental "version 4" format of the index file has been
+   introduced to reduce on-disk footprint and I/O overhead.
+
+ * "git archive" learned to produce its output without reading the
+   blob object it writes out in memory in its entirety.
+
+ * "git index-pack" that runs when fetching or pushing objects to
+   complete the packfile on the receiving end learned to use multiple
+   threads to do its job when available.
+
+ * The code to compute hash values for lines used by the internal diff
+   engine was optimized on little-endian machines, using the same
+   trick the kernel folks came up with.
+
+ * "git apply" had some memory leaks plugged.
+
+ * Setting up a revision traversal with many starting points was
+   inefficient as these were placed in a date-order priority queue
+   one-by-one.  Now they are collected in the queue unordered first,
+   and sorted immediately before getting used.
+
+ * More lower-level commands learned to use the streaming API to read
+   from the object store without keeping everything in core.
+
+ * The weighting parameters to suggestion command name typo have been
+   tweaked, so that "git tags" will suggest "tag?" and not "stage?".
+
+ * Because "sh" on the user's PATH may be utterly broken on some
+   systems, run-command API now uses SHELL_PATH, not /bin/sh, when
+   spawning an external command (not applicable to Windows port).
+
+ * The API to iterate over the refs/ hierarchy has been tweaked to
+   allow walking only a subset of it more efficiently.
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.7.10
+-------------------
+
+Unless otherwise noted, all the fixes since v1.7.10 in the maintenance
+releases are contained in this release (see release notes to them for
+details).
+
+ * "git submodule init" used to report "registered for path ..."
+   even for submodules that were registered earlier.
+   (cherry-pick c1c259e jl/submodule-report-new-path-once later to maint).
+
+ * "git diff --stat" used to fully count a binary file with modified
+   execution bits whose contents is unmodified, which was not quite
+   right.

+
+ * "git cherry-pick A C B" used to replay changes in A and then B and
+   then C if these three commits had committer timestamps in that
+   order, which is not what the user who said "A C B" naturally
+   expects.
+
+ * "git commit --amend" let the user edit the log message and then
+   died when the human-readable committer name was given
+   insufficiently by getpwent(3).
+
+ * Some capabilities were asked by fetch-pack even when upload-pack
+   did not advertise that they are available.  fetch-pack has been
+   fixed not to do so.
+
+ * "git diff" had a confusion between taking data from a path in the

+
+ * "git send-email" did not unquote encoded words that appear on the

+
+ * The interactive prompt "git send-email" gives was error prone. It
+   asked "What e-mail address do you want to use?" with the address it
+   guessed (correctly) the user would want to use in its prompt,
+   tempting the user to say "y". But the response was taken as "No,
+   please use 'y' as the e-mail address instead", which is most
+   certainly not what the user meant.
+
+ * "gitweb" when used with PATH_INFO failed to notice directories with
+   SP (and other characters that need URL-style quoting) in them.
+
+ * When the user gives an argument that can be taken as both a
+   revision name and a pathname without disambiguating with "--", we
+   used to give a help message "Use '--' to separate".  The message

+   started to fail.  Protect them from such a misconfiguration.
+
+ * The attribute system may be asked for a path that itself or its
+   leading directories no longer exists in the working tree, and it is
+   fine if we cannot open .gitattribute file in such a case.  Failure
+   to open per-directory .gitattributes with error status other than
+   ENOENT and ENOTDIR should be diagnosed, but it wasn't.
+
+ * After "gitk" showed the contents of a tag, neither "Reread
+   references" nor "Reload" did not update what is shown as the
+   contents of it, when the user overwrote the tag with "git tag -f".
+
+ * "ciabot" script (in contrib/) has been updated with extensive
+   documentation.
+
+ * "git-jump" script (in contrib/) did not work well when
+   diff.noprefix or diff.mnemonicprefix is in effect.
+
+ * Older parts of the documentation described as if having a regular
+   file in .git/refs/ hierarchy were the only way to have branches and
+   tags, which is not true for quite some time.
+
+ * A utility shell function test_seq has been added as a replacement
+   for the 'seq' utility found on some platforms.
+
+ * Compatibility wrapper to learn the maximum number of file
+   descriptors we can open around sysconf(_SC_OPEN_MAX) and
+   getrlimit(RLIMIT_NO_FILE) has been introduced for portability.
+
+ * We used curl_easy_strerror() without checking version of cURL,
+   breaking the build for versions before curl 7.12.0.
+
+ * Code to work around MacOS X UTF-8 gotcha has been cleaned up.

+Git 1.7.12.2 Release Notes
+==========================
+
+Fixes since v1.7.12.1
+---------------------
+
+ * When "git am" is fed an input that has multiple "Content-type: ..."
+   header, it did not grok charset= attribute correctly.
+
+ * Even during a conflicted merge, "git blame $path" always meant to
+   blame uncommitted changes to the "working tree" version; make it
+   more useful by showing cleanly merged parts as coming from the other
+   branch that is being merged.
+
+ * "git blame MAKEFILE" run in a history that has "Makefile" but not
+   "MAKEFILE" should say "No such file MAKEFILE in HEAD", but got
+   confused on a case insensitive filesystem and failed to do so.
+
+ * "git fetch --all", when passed "--no-tags", did not honor the
+   "--no-tags" option while fetching from individual remotes (the same
+   issue existed with "--tags", but combination "--all --tags" makes
+   much less sense than "--all --no-tags").
+
+ * "git log/diff/format-patch --stat" showed the "N line(s) added"
+   comment in user's locale and caused careless submitters to send
+   patches with such a line in them to projects whose project language
+   is not their language, mildly irritating others. Localization to
+   the line has been disabled for now.
+
+ * "git log --all-match --grep=A --grep=B" ought to show commits that
+   mention both A and B, but when these three options are used with
+   --author or --committer, it showed commits that mention either A or
+   B (or both) instead.
+
+ * The subcommand to remove the definition of a remote in "git remote"
+   was named "rm" even though all other subcommands were spelled out.
+   Introduce "git remote remove" to remove confusion, and keep "rm" as
+   a backward compatible synonym.
+
+Also contains a handful of documentation updates.

+   subsequent "git fetch" to slurp all the other branches, defeating
+   the whole point of specifying "only this branch".
+
+ * "git fetch" over http had an old workaround for an unlikely server
+   misconfiguration; it turns out that this hurts debuggability of the
+   configuration in general, and has been reverted.
+
+ * "git fetch" over http advertised that it supports "deflate", which
+   is much less common, and did not advertise the more common "gzip" on
+   its Accept-Encoding header.
+
+ * "git receive-pack" (the counterpart to "git push") did not give
+   progress output while processing objects it received to the puser
+   when run over the smart-http protocol.
+
+ * "git status" honored the ignore=dirty settings in .gitmodules but
+   "git commit" didn't.
+
+Also contains a handful of documentation updates.

+Git 1.7.12.4 Release Notes
+==========================
+
+Fixes since v1.7.12.3
+---------------------
+
+ * "git fetch" over the dumb-http revision walker could segfault when
+   curl's multi interface was used.
+
+ * It was possible to give specific paths for "asciidoc" and other
+   tools in the documentation toolchain, but not for "xmlto".
+
+ * "gitweb" did not give the correct committer timezone in its feed
+   output due to a typo.
+
+ * The "-Xours" (and similarly -Xtheirs) backend option to "git
+   merge -s recursive" was ignored for binary files.  Now it is
+   honored.
+
+ * The "binary" synthetic attribute made "diff" to treat the path as
+   binary, but not "merge".
+
+Also contains many documentation updates.

+Git v1.7.12 Release Notes
+=========================
+
+Updates since v1.7.11
+---------------------
+
+UI, Workflows & Features
+
+ * Git can be told to normalize pathnames it read from readdir(3) and
+   all arguments it got from the command line into precomposed UTF-8
+   (assuming that they come as decomposed UTF-8), in order to work
+   around issues on Mac OS.
+
+   I think there still are other places that need conversion
+   (e.g. paths that are read from stdin for some commands), but this
+   should be a good first step in the right direction.
+
+ * Per-user $HOME/.gitconfig file can optionally be stored in
+   $HOME/.config/git/config instead, which is in line with XDG.
+
+ * The value of core.attributesfile and core.excludesfile default to
+   $HOME/.config/git/attributes and $HOME/.config/git/ignore respectively
+   when these files exist.
+
+ * Logic to disambiguate abbreviated object names have been taught to
+   take advantage of object types that are expected in the context,
+   e.g. XXXXXX in the "git describe" output v1.2.3-gXXXXXX must be a
+   commit object, not a blob nor a tree.  This will help us prolong
+   the lifetime of abbreviated object names.
+
+ * "git apply" learned to wiggle the base version and perform three-way
+   merge when a patch does not exactly apply to the version you have.
+
+ * Scripted Porcelain writers now have access to the credential API via
+   the "git credential" plumbing command.
+
+ * "git help" used to always default to "man" format even on platforms
+   where "man" viewer is not widely available.
+
+ * "git clone --local $path" started its life as an experiment to
+   optionally use link/copy when cloning a repository on the disk, but
+   we didn't deprecate it after we made the option a no-op to always
+   use the optimization.  The command learned "--no-local" option to
+   turn this off, as a more explicit alternative over use of file://
+   URL.
+
+ * "git fetch" and friends used to say "remote side hung up
+   unexpectedly" when they failed to get response they expect from the
+   other side, but one common reason why they don't get expected
+   response is that the remote repository does not exist or cannot be
+   read. The error message in this case was updated to give better
+   hints to the user.
+
+ * "git help -w $cmd" can show HTML version of documentation for
+   "git-$cmd" by setting help.htmlpath to somewhere other than the
+   default location where the build procedure installs them locally;
+   the variable can even point at a http:// URL.
+
+ * "git rebase [-i] --root $tip" can now be used to rewrite all the
+   history leading to "$tip" down to the root commit.
+
+ * "git rebase -i" learned "-x <cmd>" to insert "exec <cmd>" after
+   each commit in the resulting history.
+
+ * "git status" gives finer classification to various states of paths
+   in conflicted state and offer advice messages in its output.
+
+ * "git submodule" learned to deal with nested submodule structure
+   where a module is contained within a module whose origin is
+   specified as a relative URL to its superproject's origin.
+
+ * A rather heavy-ish "git completion" script has been split to create
+   a separate "git prompting" script, to help lazy-autoloading of the
+   completion part while making prompting part always available.
+
+ * "gitweb" pays attention to various forms of credits that are
+   similar to "Signed-off-by:" lines in the commit objects and
+   highlights them accordingly.
+
+
+Foreign Interface
+
+ * "mediawiki" remote helper (in contrib/) learned to handle file
+   attachments.
+
+ * "git p4" now uses "Jobs:" and "p4 move" when appropriate.
+
+ * vcs-svn has been updated to clean-up compilation, lift 32-bit
+   limitations, etc.
+
+
+Performance, Internal Implementation, etc. (please report possible regressions)
+
+ * Some tests showed false failures caused by a bug in ecryptofs.
+
+ * We no longer use AsciiDoc7 syntax in our documentation and favor a
+   more modern style.
+
+ * "git am --rebasing" codepath was taught to grab authorship, log
+   message and the patch text directly out of existing commits.  This
+   will help rebasing commits that have confusing "diff" output in
+   their log messages.
+
+ * "git index-pack" and "git pack-objects" use streaming API to read
+   from the object store to avoid having to hold a large blob object
+   in-core while they are doing their thing.
+
+ * Code to match paths with exclude patterns learned to avoid calling
+   fnmatch() by comparing fixed leading substring literally when
+   possible.
+
+ * "git log -n 1 -- rarely-touched-path" was spending unnecessary
+   cycles after showing the first change to find the next one, only to
+   discard it.
+
+ * "git svn" got a large-looking code reorganization at the last
+   minute before the code freeze.
+
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.7.11
+-------------------
+
+Unless otherwise noted, all the fixes since v1.7.11 in the maintenance
+releases are contained in this release (see release notes to them for
+details).
+
+ * "git submodule add" was confused when the superproject did not have
+   its repository in its usual place in the working tree and GIT_DIR
+   and GIT_WORK_TREE was used to access it.
+
+ * "git commit --amend" let the user edit the log message and then died
+   when the human-readable committer name was given insufficiently by
+   getpwent(3).

+Git v1.7.2.1 Release Notes
+==========================
+
+Fixes since v1.7.2
+------------------
+
+ * "git instaweb" wasn't useful when your Apache was installed under a
+   name other than apache2 (e.g. "httpd").
+
+ * Similarly, "git web--browse" (invoked by "git help -w") learned that
+   chrome browser is sometimes called google-chrome.
+
+ * An overlong line after ".gitdir: " in a git file caused out of bounds
+   access to an array on the stack.
+
+ * "git config --path conf.var" to attempt to expand a variable conf.var
+   that uses "~/" short-hand segfaulted when $HOME environment variable
+   was not set.
+
+ * Documentation on Cygwin failed to build.
+
+ * The error message from "git pull blarg" when 'blarg' is an unknown
+   remote name has been improved.
+
+And other minor fixes and documentation updates.

+Git v1.7.2.3 Release Notes
+==========================
+
+Fixes since v1.7.2.2
+--------------------
+
+ * When people try insane things such as delta-compressing 4GiB files, we
+   threw an assertion failure.
+
+ * "git archive" gave the full commit ID for "$Format:%h$".
+
+ * "git fetch --tags" did not fetch tags when remote.<nick>.tagopt was set

+   setting.
+
+ * "git for-each-ref --format='%(objectname:short)'" has been completely

+
+ * "git gc" incorrectly pruned a rerere record that was created long

+
+ * "git log --follow -M -p" was seriously broken in 1.7.2, reporting
+   assertion failure.
+
+ * Running "git log" with an incorrect option started pager nevertheless,
+   forcing the user to dismiss it.
+
+ * "git rebase" did not work well when the user has diff.renames
+   configuration variable set.
+
+ * An earlier (and rather old) fix to "git rebase" against a rebased
+   upstream broke a more normal, non rebased upstream case rather badly,
+   attempting to re-apply patches that are already accepted upstream.
+
+ * "git submodule sync" forgot to update the superproject's config file
+   when submodule URL changed.
+
+ * "git pack-refs --all --prune" did not remove a directory that has
+   become empty.

+Git v1.7.2 Release Notes
+========================
+
+Updates since v1.7.1
+--------------------
+
+ * core.eol configuration and text/eol attributes are the new way to control
+   the end of line conventions for files in the working tree.
+
+ * core.autocrlf has been made safer - it will now only handle line
+   endings for new files and files that are LF-only in the
+   repository. To normalize content that has been checked in with
+   CRLF, use the new eol/text attributes.
+
+ * The whitespace rules used in "git apply --whitespace" and "git diff"
+   gained a new member in the family (tab-in-indent) to help projects with
+   policy to indent only with spaces.
+
+ * When working from a subdirectory, by default, git does not look for its
+   metadirectory ".git" across filesystems, primarily to help people who
+   have invocations of git in their custom PS1 prompts, as being outside
+   of a git repository would look for ".git" all the way up to the root
+   directory, and NFS mounts are often slow.  DISCOVERY_ACROSS_FILESYSTEM
+   environment variable can be used to tell git not to stop at a
+   filesystem boundary.
+
+ * Usage help messages generated by parse-options library (i.e. most
+   of the Porcelain commands) are sent to the standard output now.
+
+ * ':/<string>' notation to look for a commit now takes regular expression
+   and it is not anchored at the beginning of the commit log message
+   anymore (this is a backward incompatible change).
+
+ * "git" wrapper learned "-c name=value" option to override configuration
+   variable from the command line.
+
+ * Improved portability for various platforms including older SunOS,
+   HP-UX 10/11, AIX, Tru64, etc. and platforms with Python 2.4.
+
+ * The message from "git am -3" has been improved when conflict
+   resolution ended up making the patch a no-op.
+
+ * "git blame" applies the textconv filter to the contents it works
+   on, when available.
+
+ * "git checkout --orphan newbranch" is similar to "-b newbranch" but
+   prepares to create a root commit that is not connected to any existing
+   commit.
+
+ * "git cherry-pick" learned to pick a range of commits
+   (e.g. "cherry-pick A..B" and "cherry-pick --stdin"), so did "git
+   revert"; these do not support the nicer sequencing control "rebase
+   [-i]" has, though.
+
+ * "git cherry-pick" and "git revert" learned --strategy option to specify
+   the merge strategy to be used when performing three-way merges.
+
+ * "git cvsserver" can be told to use pserver; its password file can be
+   stored outside the repository.
+
+ * The output from the textconv filter used by "git diff" can be cached to
+   speed up their reuse.
+
+ * "git diff --word-diff=<mode>" extends the existing "--color-words"
+   option, making it more useful in color-challenged environments.
+
+ * The regexp to detect function headers used by "git diff" for PHP has
+   been enhanced for visibility modifiers (public, protected, etc.) to
+   better support PHP5.
+
+ * "diff.noprefix" configuration variable can be used to implicitly
+   ask for "diff --no-prefix" behaviour.
+
+ * "git for-each-ref" learned "%(objectname:short)" that gives the object
+   name abbreviated.
+
+ * "git format-patch" learned --signature option and format.signature
+   configuration variable to customize the e-mail signature used in the
+   output.
+
+ * Various options to "git grep" (e.g. --count, --name-only) work better
+   with binary files.
+
+ * "git grep" learned "-Ovi" to open the files with hits in your editor.
+
+ * "git help -w" learned "chrome" and "chromium" browsers.
+
+ * "git log --decorate" shows commit decorations in various colours.
+
+ * "git log --follow <path>" follows across copies (it used to only follow
+   renames).  This may make the processing more expensive.
+
+ * "git log --pretty=format:<template>" specifier learned "% <something>"
+   magic that inserts a space only when %<something> expands to a
+   non-empty string; this is similar to "%+<something>" magic, but is
+   useful in a context to generate a single line output.
+
+ * "git notes prune" learned "-n" (dry-run) and "-v" options, similar to
+   what "git prune" has.
+
+ * "git patch-id" can be fed a mbox without getting confused by the
+   signature line in the format-patch output.
+
+ * "git remote" learned "set-branches" subcommand.
+
+ * "git rev-list A..B" learned --ancestry-path option to further limit
+   the result to the commits that are on the ancestry chain between A and
+   B (i.e. commits that are not descendants of A are excluded).
+
+ * "git show -5" is equivalent to "git show --do-walk 5"; this is similar
+   to the update to make "git show master..next" walk the history,
+   introduced in 1.6.4.
+
+ * "git status [-s] --ignored" can be used to list ignored paths.
+
+ * "git status -s -b" shows the current branch in the output.
+
+ * "git status" learned "--ignore-submodules" option.
+
+ * Various "gitweb" enhancements and clean-ups, including syntax
+   highlighting, "plackup" support for instaweb, .fcgi suffix to run
+   it as FastCGI script, etc.
+
+ * The test harness has been updated to produce TAP-friendly output.
+
+ * Many documentation improvement patches are also included.
+
+
+Fixes since v1.7.1
+------------------
+
+All of the fixes in v1.7.1.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * We didn't URL decode "file:///path/to/repo" correctly when path/to/repo
+   had percent-encoded characters (638794c, 9d2e942, ce83eda, 3c73a1d).
+
+ * "git clone" did not configure remote.origin.url correctly for bare
+   clones (df61c889).
+
+ * "git diff --graph" works better with "--color-words" and other options
+   (81fa024..4297c0a).
+
+ * "git diff" could show ambiguous abbreviation of blob object names on
+   its "index" line (3e5a188).
+
+ * "git reset --hard" started from a wrong directory and a working tree in
+   a nonstandard location is in use got confused (560fb6a1).
+
+ * "git read-tree -m A B" used to switch to branch B while retaining
+   local changes added an incorrect cache-tree information (b1f47514).

+
+ * Running "git cherry-pick --ff" on a root commit segfaulted.
+
+ * "diff", "blame" and friends incorrectly applied textconv filters to
+   symlinks.
+
+ * Highlighting of whitespace breakage in "diff" output was showing
+   incorrect amount of whitespaces when blank-at-eol is set and the line
+   consisted only of whitespaces and a TAB.
+
+ * "diff" was overly inefficient when trying to find the line to use for
+   the function header (i.e. equivalent to --show-c-function of GNU diff).
+
+ * "git imap-send" depends on libcrypto but our build rule relied on the
+   linker to implicitly link it via libssl, which was wrong.
+
+ * "git merge-file" can be called from within a subdirectory now.
+
+ * "git repack -f" expanded and recompressed non-delta objects in the
+   existing pack, which was wasteful.  Use new "-F" option if you really
+   want to (e.g. when changing the pack.compression level).
+
+ * "git rev-list --format="...%x00..." incorrectly chopped its output
+   at NUL.
+
+ * "git send-email" did not correctly remove duplicate mail addresses from
+   the Cc: header that appear on the To: header.

+   unless Gnus is used.
+
+ * "git-p4" (in contrib/) did not correctly handle deleted files.

+
+ * Smart HTTP transport used to incorrectly retry redirected POST

+ * "git checkout" removed an untracked file "foo" from the working

+   "foo/bar".  Prevent this, just like the case where the conflicting
+   path were "foo" (c752e7f..7980872d).
+
+ * "git cherry-pick" or "git revert" refused to work when a path that

+ * "git imap-send" failed to build under NO_OPENSSL.
+
+ * Setting log.decorate configuration variable to "0" or "1" to mean

+Git 1.7.3.5 Release Notes
+=========================
+
+ * The xfuncname pattern used by "git diff" and "git grep" to show the
+   last notable line in context were broken for python and ruby for a long
+   time.
+
+ * "git merge" into an unborn branch removed an untracked file "foo" from
+   the working tree when merged branch had "foo" (this fix was already in
+   1.7.3.3 but was omitted from the release notes by mistake).
+
+ * "git status -s" did not quote unprintable characters in paths as
+   documented.
+
+ * "git am --abort" used to always reset to the commit at the beginning of
+   the last "am" invocation that has stopped, losing any unrelated commits
+   that may have been made since then.  Now it refrains from doing so and
+   instead issues a warning.
+
+ * "git blame" incorrectly reused bogusly cached result of textconv
+   filter for files from the working tree.
+
+ * "git commit" used to abort after the user edited the log message
+   when the committer information was not correctly set up.  It now
+   aborts before starting the editor.
+
+ * "git commit --date=invalid" used to silently ignore the incorrectly
+   specified date; it is now diagnosed as an error.
+
+ * "git rebase --skip" to skip the last commit in a series used to fail
+   to run post-rewrite hook and to copy notes from old commits that have
+   successfully been rebased so far.  Now it do (backmerge ef88ad2).
+
+ * "gitweb" tried to show a wrong feed logo when none was specified.

+Git v1.7.3 Release Notes
+========================
+
+Updates since v1.7.2
+--------------------
+
+ * git-gui, now at version 0.13.0, got various updates and a new
+   maintainer, Pat Thoyts.
+
+ * Gitweb allows its configuration to change per each request; it used to
+   read the configuration once upon startup.
+
+ * When git finds a corrupt object, it now reports the file that contains
+   it.
+
+ * "git checkout -B <it>" is a shorter way to say "git branch -f <it>"
+   followed by "git checkout <it>".
+
+ * When "git checkout" or "git merge" refuse to proceed in order to
+   protect local modification to your working tree, they used to stop
+   after showing just one path that might be lost.  They now show all,
+   in a format that is easier to read.
+
+ * "git clean" learned "-e" ("--exclude") option.
+
+ * Hunk headers produced for C# files by "git diff" and friends show more
+   relevant context than before.
+
+ * diff.ignoresubmodules configuration variable can be used to squelch the
+   differences in submodules reported when running commands (e.g. "diff",
+   "status", etc.) at the superproject level.
+
+ * http.useragent configuration can be used to lie who you are to your
+   restrictive firewall.
+
+ * "git rebase --strategy <s>" learned "-X" option to pass extra options
+   that are understood by the chosen merge strategy.
+
+ * "git rebase -i" learned "exec" that you can insert into the insn sheet
+   to run a command between its steps.
+
+ * "git rebase" between branches that have many binary changes that do
+   not conflict should be faster.
+
+ * "git rebase -i" peeks into rebase.autosquash configuration and acts as
+   if you gave --autosquash from the command line.
+
+
+Also contains various documentation updates.
+
+
+Fixes since v1.7.2
+------------------
+
+All of the fixes in v1.7.2.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git merge -s recursive" (which is the default) did not handle cases
+   where a directory becomes a file (or vice versa) very well.
+
+ * "git fetch" and friends were accidentally broken for url with "+" in
+   its path, e.g. "git://git.gnome.org/gtk+".
+
+ * "git fetch $url" (i.e. without refspecs) was broken for quite some
+   time, if the current branch happen to be tracking some remote.
+
+ * "git ls-tree dir dirgarbage", when "dir" was a directory,
+   incorrectly recursed into "dir".
+
+ * "git note remove" created unnecessary extra commit when named object
+   did not have any note to begin with.
+
+ * "git rebase" did not work well if you had diff.noprefix configured.
+
+ * "git -c foo=bar subcmd" did not work well for subcmd that is not
+   implemented as a built-in command.

+Git v1.7.4.1 Release Notes
+==========================
+
+Fixes since v1.7.4
+------------------
+
+ * On Windows platform, the codepath to spawn a new child process forgot
+   to first flush the output buffer.
+
+ * "git bundle" did not use OFS_DELTA encoding, making its output a few
+   per-cent larger than necessarily.
+
+ * The option to tell "git clone" to recurse into the submodules was
+   misspelled with an underscore "--recurse_submodules".
+
+ * "git diff --cached HEAD" before the first commit does what an end user
+   would expect (namely, show what would be committed without further "git
+   add").
+
+ * "git fast-import" didn't accept the command to ask for "notes" feature
+   to be present in its input stream, even though it was capable of the
+   feature.
+
+ * "git fsck" gave up scanning loose object files in directories with
+   garbage files.
+
+And other minor fixes and documentation updates.

+Git v1.7.4.2 Release Notes
+==========================
+
+Fixes since v1.7.4.1
+--------------------
+
+ * Many documentation updates to match "git cmd -h" output and the
+   git-cmd manual page.
+
+ * We used to keep one file descriptor open for each and every packfile
+   that we have a mmap window on it (read: "in use"), even when for very
+   tiny packfiles.  We now close the file descriptor early when the entire
+   packfile fits inside one mmap window.
+
+ * "git bisect visualize" tried to run "gitk" in windowing
+   environments even when "gitk" is not installed, resulting in a
+   strange error message.
+
+ * "git clone /no/such/path" did not fail correctly.
+
+ * "git commit" did not correctly error out when the user asked to use a
+   non existent file as the commit message template.
+
+ * "git diff --stat -B" ran on binary files counted the changes in lines,
+   which was nonsensical.
+
+ * "git diff -M" opportunistically detected copies, which was not
+   necessarily a good thing, especially when it is internally run by
+   recursive merge.
+
+ * "git difftool" didn't tell (g)vimdiff that the files it is reading are
+   to be opened read-only.
+
+ * "git merge" didn't pay attention to prepare-commit-msg hook, even
+   though if a merge is conflicted and manually resolved, the subsequent
+   "git commit" would have triggered the hook, which was inconsistent.
+
+ * "git patch-id" (and commands like "format-patch --ignore-in-upstream"
+   that use it as their internal logic) handled changes to files that end
+   with incomplete lines incorrectly.
+
+ * The official value to tell "git push" to push the current branch back
+   to update the upstream branch it forked from is now called "upstream".
+   The old name "tracking" is and will be supported.
+
+ * "git submodule update" used to honor the --merge/--rebase option (or
+   corresponding configuration variables) even for a newly cloned
+   subproject, which made no sense (so/submodule-no-update-first-time).
+
+ * gitweb's "highlight" interface mishandled tabs.
+
+ * gitweb didn't understand timezones with GMT offset that is not
+   multiple of a whole hour.
+
+ * gitweb had a few forward-incompatible syntactic constructs and
+   also used incorrect variable when showing the file mode in a diff.
+
+And other minor fixes and documentation updates.

+Git v1.7.4.3 Release Notes
+==========================
+
+Fixes since v1.7.4.2
+--------------------
+
+ * "git apply" used to confuse lines updated by previous hunks as lines
+   that existed before when applying a hunk, contributing misapplication
+   of patches with offsets.
+
+ * "git branch --track" (and "git checkout --track --branch") used to
+   allow setting up a random non-branch that does not make sense to follow
+   as the "upstream".  The command correctly diagnoses it as an error.
+
+ * "git checkout $other_branch" silently removed untracked symbolic links
+   in the working tree that are in the way in order to check out paths
+   under it from the named branch.
+
+ * "git cvsimport" did not bail out immediately when the cvs server cannot
+   be reached, spewing unnecessary error messages that complain about the
+   server response that it never got.
+
+ * "git diff --quiet" did not work very well with the "--diff-filter"
+   option.
+
+ * "git grep -n" lacked a long-hand synonym --line-number.
+
+ * "git stash apply" reported the result of its operation by running
+   "git status" from the top-level of the working tree; it should (and
+   now does) run it from the user's working directory.
+
+And other minor fixes and documentation updates.

+Git v1.7.4 Release Notes
+========================
+
+Updates since v1.7.3
+--------------------
+
+ * The documentation Makefile now assumes by default asciidoc 8 and
+   docbook-xsl >= 1.73. If you have older versions, you can set
+   ASCIIDOC7 and ASCIIDOC_ROFF, respectively.
+
+ * The option parsers of various commands that create new branches (or
+   rename existing ones to a new name) were too loose and users were
+   allowed to give a branch a name that begins with a dash by creative
+   abuse of their command line options, which only led to burning
+   themselves.  The name of a branch cannot begin with a dash now.
+
+ * System-wide fallback default attributes can be stored in
+   /etc/gitattributes; the core.attributesfile configuration variable can
+   be used to customize the path to this file.
+
+ * The thread structure generated by "git send-email" has changed
+   slightly.  Setting the cover letter of the latest series as a reply
+   to the cover letter of the previous series with --in-reply-to used
+   to make the new cover letter and all the patches replies to the
+   cover letter of the previous series; this has been changed to make
+   the patches in the new series replies to the new cover letter.
+
+ * The Bash completion script in contrib/ has been adjusted to be usable with
+   Bash 4 (options with '=value' didn't complete).  It has been also made
+   usable with zsh.
+
+ * Different pagers can be chosen depending on which subcommand is
+   being run under the pager, using the "pager.<subcommand>" variable.
+
+ * The hardcoded tab-width of 8 that is used in whitespace breakage checks is now
+   configurable via the attributes mechanism.
+
+ * Support of case insensitive filesystems (i.e. "core.ignorecase") has
+   been improved.  For example, the gitignore mechanism didn't pay attention
+   to case insensitivity.
+
+ * The <tree>:<path> syntax for naming a blob in a tree, and the :<path>
+   syntax for naming a blob in the index (e.g. "master:Makefile",
+   ":hello.c") have been extended.  You can start <path> with "./" to
+   implicitly have the (sub)directory you are in prefixed to the
+   lookup.  Similarly, ":../Makefile" from a subdirectory would mean
+   "the Makefile of the parent directory in the index".
+
+ * "git blame" learned the --show-email option to display the e-mail
+   addresses instead of the names of authors.
+
+ * "git commit" learned the --fixup and --squash options to help later invocation
+   of interactive rebase.
+
+ * Command line options to "git cvsimport" whose names are in capital
+   letters (-A, -M, -R and -S) can now be specified as the default in
+   the .git/config file by their longer names (cvsimport.authorsFile,
+   cvsimport.mergeRegex, cvsimport.trackRevisions, cvsimport.ignorePaths).
+
+ * "git daemon" can be built in the MinGW environment.
+
+ * "git daemon" can take more than one --listen option to listen to
+   multiple addresses.
+
+ * "git describe --exact-match" was optimized not to read commit
+   objects unnecessarily.
+
+ * "git diff" and "git grep" learned what functions and subroutines
+   in Fortran, Pascal and Perl look like.
+
+ * "git fetch" learned the "--recurse-submodules" option.
+
+ * "git mergetool" tells vim/gvim to show a three-way diff by default
+   (use vimdiff2/gvimdiff2 as the tool name for old behavior).
+
+ * "git log -G<pattern>" limits the output to commits whose change has
+   added or deleted lines that match the given pattern.
+
+ * "git read-tree" with no argument as a way to empty the index is
+   deprecated; we might want to remove it in the future.  Users can
+   use the new --empty option to be more explicit instead.
+
+ * "git repack -f" does not spend cycles to recompress objects in the
+   non-delta representation anymore (use -F if you really mean it
+   e.g. after you changed the core.compression variable setting).
+
+ * "git merge --log" used to limit the resulting merge log to 20
+   entries; this is now customizable by giving e.g. "--log=47".
+
+ * "git merge" may work better when all files were moved out of a
+   directory in one branch while a new file is created in place of that
+   directory in the other branch.
+
+ * "git merge" learned the "--abort" option, synonymous to
+   "git reset --merge" when a merge is in progress.
+
+ * "git notes" learned the "merge" subcommand to merge notes refs.
+   In addition to the default manual conflict resolution, there are
+   also several notes merge strategies for automatically resolving
+   notes merge conflicts.
+
+ * "git rebase --autosquash" can use SHA-1 object names to name the
+   commit which is to be fixed up (e.g. "fixup! e83c5163").
+
+ * The default "recursive" merge strategy learned the --rename-threshold
+   option to influence the rename detection, similar to the -M option
+   of "git diff".  From the "git merge" frontend, the "-X<strategy option>"
+   interface, e.g. "git merge -Xrename-threshold=50% ...", can be used
+   to trigger this.
+
+ * The "recursive" strategy also learned to ignore various whitespace
+   changes; the most notable is -Xignore-space-at-eol.
+
+ * "git send-email" learned "--to-cmd", similar to "--cc-cmd", to read
+   the recipient list from a command output.
+
+ * "git send-email" learned to read and use "To:" from its input files.
+
+ * you can extend "git shell", which is often used on boxes that allow
+   git-only login over ssh as login shell, with a custom set of
+   commands.
+
+ * The current branch name in "git status" output can be colored differently
+   from the generic header color by setting the "color.status.branch" variable.
+
+ * "git submodule sync" updates metainformation for all submodules,
+   not just the ones that have been checked out.
+
+ * gitweb can use a custom 'highlight' command with its configuration file.
+
+ * other gitweb updates.
+
+
+Also contains various documentation updates.
+
+
+Fixes since v1.7.3
+------------------
+
+All of the fixes in the v1.7.3.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git log --author=me --author=her" did not find commits written by
+   me or by her; instead it looked for commits written by me and by
+   her, which is impossible.
+
+ * "git push --progress" shows progress indicators now.
+
+ * "git rebase -i" showed a confusing error message when given a
+   branch name that does not exist.
+
+ * "git repack" places its temporary packs under $GIT_OBJECT_DIRECTORY/pack
+   instead of $GIT_OBJECT_DIRECTORY/ to avoid cross directory renames.
+
+ * "git submodule update --recursive --other-flags" passes flags down
+   to its subinvocations.

+Git v1.7.5.1 Release Notes
+==========================
+
+Fixes since v1.7.5
+------------------
+
+ * When an object "$tree:$path" does not exist, if $path does exist in the
+   subtree of $tree that corresponds to the subdirectory the user is in,
+   git now suggests using "$tree:./$path" in addition to the advice to use
+   the full path from the root of the working tree.
+
+ * The "--date=relative" output format used to say "X years, 12 months"
+   when it should have said "X+1 years".
+
+ * The smart-HTTP transfer was broken in 1.7.5 when the client needs
+   to issue a small POST (which uses content-length) and then a large
+   POST (which uses chunked) back to back.
+
+ * "git clean" used to fail on an empty directory that is not readable,
+   even though rmdir(2) could remove such a directory.  Now we attempt it
+   as the last resort.
+
+ * The "--dirstat" option of "diff" family of commands used to totally
+   ignore a change that only rearranged lines within a file.  Such a
+   change now counts as at least a minimum but non zero change.
+
+ * The "--dirstat" option of "diff" family of commands used to use the
+   pathname in the original, instead of the pathname in the result,
+   when renames are involved.
+
+ * "git pack-object" did not take core.bigfilethreashold into account
+   (unlike fast-import); now it does.
+
+ * "git reflog" ignored options like "--format=.." on the command line.
+
+ * "git stash apply" used to refuse to work if there was any change in
+   the working tree, even when the change did not overlap with the change
+   the stash recorded.
+
+ * "git stash apply @{99999}" was not diagnosed as an error, even when you
+   did not have that many stash entries.
+
+ * An error message from "git send-email" to diagnose a broken SMTP
+   connection configuration lacked a space between "hello=<smtp-domain>"
+   and "port=<smtp-server-port>".
+
+And other minor fixes and documentation updates.

+Git v1.7.5.2 Release Notes
+==========================
+
+The release notes to 1.7.5.1 forgot to mention:
+
+ * "git stash -p --no-keep-index" and "git stash --no-keep-index -p" now
+   mean the same thing.
+
+ * "git upload-pack" (hence "git push" over git native protocol) had a
+   subtle race condition that could lead to a deadlock.
+
+Fixes since v1.7.5.1
+--------------------
+
+ * "git add -p" did not work correctly when a hunk is split and then
+   one of them was given to the editor.
+
+ * "git add -u" did not resolve a conflict where our history deleted and
+   their history modified the same file, and the working tree resolved to
+   keep a file.
+
+ * "git cvsimport" did not know that CVSNT stores its password file in a
+   location different from the traditional CVS.
+
+ * "git diff-files" did not show the mode information from the working
+   tree side of an unmerged path correctly.
+
+ * "git diff -M --cached" used to use unmerged path as a possible rename
+   source candidate, which made no sense.
+
+ * The option name parser in "git fast-import" used prefix matches for
+   some options where it shouldn't, and accepted non-existent options,
+   e.g. "--relative-marksmith" or "--forceps".
+
+ * "git format-patch" did not quote RFC822 special characters in the
+   email address (e.g From: Junio C. Hamano <jch@example.com>, not
+   From: "Junio C. Hamano" <jch@example.com>).
+
+ * "git format-patch" when run with "--quiet" option used to produce a
+   nonsense result that consists of alternating empty output.
+
+ * In "git merge", per-branch branch.<name>.mergeoptions configuration
+   variables did not override the fallback default merge.<option>
+   configuration variables such as merge.ff, merge.log, etc.
+
+ * "git merge-one-file" did not honor GIT_WORK_TREE settings when
+   handling a "both sides added, differently" conflict.
+
+ * "git mergetool" did not handle conflicted submoudules gracefully.
+
+ * "git-p4" (in contrib) used a wrong base image while merge a file that
+   was added on both branches differently.
+
+ * "git rebase -i -p" failed to preserve the history when there is a
+   redundant merge created with the --no-ff option.
+
+And other minor fixes and documentation updates.

+   of the tarball generation; this was bad because snapshot from the same
+   tree should result in a same tarball.
+
+And other minor fixes and documentation updates.

+Git v1.7.5.4 Release Notes
+==========================
+
+Fixes since v1.7.5.3
+--------------------
+
+ * The single-key mode of "git add -p" was easily fooled into thinking
+   that it was told to add everything ('a') when up-arrow was pressed by
+   mistake.
+
+ * Setting a git command that uses custom configuration via "-c var=val"
+   as an alias caused a crash due to a realloc(3) failure.
+
+ * "git diff -C -C" used to disable the rename detection entirely when
+   there are too many copy candidate paths in the tree; now it falls
+   back to "-C" when doing so would keep the copy candidate paths
+   under the rename detection limit.
+
+ * "git rerere" did not diagnose a corrupt MERGE_RR file in some cases.
+
+And other minor fixes and documentation updates.

+Git v1.7.5 Release Notes
+========================
+
+Updates since v1.7.4
+--------------------
+
+ * Various MinGW portability fixes.
+
+ * Various git-p4 enhancements (in contrib).
+
+ * Various vcs-svn, git-svn and gitk enhancements and fixes.
+
+ * Various git-gui updates (0.14.0).
+
+ * Update to more modern HP-UX port.
+
+ * The codebase is getting prepared for i18n/l10n; no translated
+   strings nor translation mechanism in the code yet, but the strings
+   are being marked for l10n.
+
+ * The bash completion script can now complete symmetric difference
+   for "git diff" command, e.g. "git diff ...bra<TAB>".
+
+ * The default minimum length of abbreviated and unique object names
+   can now be configured by setting the core.abbrev configuration
+   variable.
+
+ * "git apply -v" reports offset lines when the patch does not apply at
+   the exact location recorded in the diff output.
+
+ * "git config" used to be also known as "git repo-config", but the old
+   name is now officially deprecated.
+
+ * "git checkout --detach <commit>" is a more user friendly synonym for
+   "git checkout <commit>^0".
+
+ * "git checkout" performed on detached HEAD gives a warning and
+   advice when the commit being left behind will become unreachable from
+   any branch or tag.
+
+ * "git cherry-pick" and "git revert" can be told to use a custom merge
+   strategy, similar to "git rebase".
+
+ * "git cherry-pick" remembers which commit failed to apply when it is
+   stopped by conflicts, making it unnecessary to use "commit -c $commit"
+   to conclude it.
+
+ * "git cvsimport" bails out immediately when the cvs server cannot be
+   reached, without spewing unnecessary error messages that complain about
+   the server response it never got.
+
+ * "git fetch" vs "git upload-pack" transfer learned 'no-done'
+   protocol extension to save one round-trip after the content
+   negotiation is done. This saves one HTTP RPC, reducing the overall
+   latency for a trivial fetch.
+
+ * "git fetch" can be told to recursively fetch submodules on-demand.
+
+ * "git grep -f <filename>" learned to treat "-" as "read from the
+   standard input stream".
+
+ * "git grep --no-index" did not honor pathspecs correctly, returning
+   paths outside the specified area.
+
+ * "git init" learned the --separate-git-dir option to allow the git
+   directory for a new repository created elsewhere and linked via the
+   gitdir mechanism. This is primarily to help submodule support later
+   to switch between a branch of superproject that has the submodule
+   and another that does not.
+
+ * "git log" type commands now understand globbing pathspecs.  You
+   can say "git log -- '*.txt'" for example.
+
+ * "git log" family of commands learned --cherry and --cherry-mark
+   options that can be used to view two diverged branches while omitting
+   or highlighting equivalent changes that appear on both sides of a
+   symmetric difference (e.g. "log --cherry A...B").
+
+ * A lazy "git merge" that didn't say what to merge used to be an error.
+   When run on a branch that has an upstream defined, however, the command
+   now merges from the configured upstream.
+
+ * "git mergetool" learned how to drive "beyond compare 3" as well.
+
+ * "git rerere forget" without pathspec used to forget all the saved
+   conflicts that relate to the current merge; it now requires you to
+   give it pathspecs.
+
+ * "git rev-list --objects $revs -- $pathspec" now limits the objects listed
+   in its output properly with the pathspec, in preparation for narrow
+   clones.
+
+ * "git push" with no parameters gives better advice messages when
+   "tracking" is used as the push.default semantics or there is no remote
+   configured yet.
+
+ * A possible value to the "push.default" configuration variable,
+   'tracking', gained a synonym that more naturally describes what it
+   does, 'upstream'.
+
+ * "git rerere" learned a new subcommand "remaining" that is similar to
+   "status" and lists the paths that had conflicts which are known to
+   rerere, but excludes the paths that have already been marked as
+   resolved in the index from its output.  "git mergetool" has been
+   updated to use this facility.
+
+Also contains various documentation updates.
+
+
+Fixes since v1.7.4
+------------------
+
+All of the fixes in the v1.7.4.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git fetch" from a client that is mostly following the remote
+   needlessly told all of its refs to the server for both sides to
+   compute the set of objects that need to be transferred efficiently,
+   instead of stopping when the server heard enough. In a project with
+   many tags, this turns out to be extremely wasteful, especially over
+   the smart HTTP transport (sp/maint-{upload,fetch}-pack-stop-early~1).
+
+ * "git fetch" run from a repository that uses the same repository as
+   its alternate object store as the repository it is fetching from
+   did not tell the server that it already has access to objects
+   reachable from the refs in their common alternate object store,
+   causing it to fetch unnecessary objects (jc/maint-fetch-alt).
+
+ * "git remote add --mirror" created a configuration that is suitable for
+   doing both a mirror fetch and a mirror push at the same time, which
+   made little sense.  We now warn and require the command line to specify
+   either --mirror=fetch or --mirror=push.

+Git v1.7.6.1 Release Notes
+==========================
+
+Fixes since v1.7.6
+------------------
+
+ * Various codepaths that invoked zlib deflate/inflate assumed that these
+   functions can compress or uncompress more than 4GB data in one call on
+   platforms with 64-bit long, which has been corrected.
+
+ * "git unexecutable" reported that "unexecutable" was not found, even
+   though the actual error was that "unexecutable" was found but did
+   not have a proper she-bang line to be executed.
+
+ * Error exits from $PAGER were silently ignored.
+
+ * "git checkout -b <branch>" was confused when attempting to create a
+   branch whose name ends with "-g" followed by hexadecimal digits,
+   and refused to work.
+
+ * "git checkout -b <branch>" sometimes wrote a bogus reflog entry,
+   causing later "git checkout -" to fail.
+
+ * "git diff --cc" learned to correctly ignore binary files.
+
+ * "git diff -c/--cc" mishandled a deletion that resolves a conflict, and
+   looked in the working tree instead.
+
+ * "git fast-export" forgot to quote pathnames with unsafe characters
+   in its output.
+
+ * "git fetch" over smart-http transport used to abort when the
+   repository was updated between the initial connection and the
+   subsequent object transfer.
+
+ * "git fetch" did not recurse into submodules in subdirectories.
+
+ * "git ls-tree" did not error out when asked to show a corrupt tree.
+
+ * "git pull" without any argument left an extra whitespace after the
+   command name in its reflog.
+
+ * "git push --quiet" was not really quiet.
+
+ * "git rebase -i -p" incorrectly dropped commits from side branches.
+
+ * "git reset [<commit>] paths..." did not reset the index entry correctly
+   for unmerged paths.
+
+ * "git submodule add" did not allow a relative repository path when
+   the superproject did not have any default remote url.
+
+ * "git submodule foreach" failed to correctly give the standard input to
+   the user-supplied command it invoked.
+
+ * submodules that the user has never showed interest in by running
+   "git submodule init" was incorrectly marked as interesting by "git
+   submodule sync".
+
+ * "git submodule update --quiet" was not really quiet.
+
+  * "git tag -l <glob>..." did not take multiple glob patterns from the
+   command line.

+Git v1.7.6 Release Notes
+========================
+
+Updates since v1.7.5
+--------------------
+
+ * Various git-svn updates.
+
+ * Updates the way content tags are handled in gitweb.  Also adds
+   a UI to choose common timezone for displaying the dates.
+
+ * Similar to branch names, tagnames that begin with "-" are now
+   disallowed.
+
+ * Clean-up of the C part of i18n (but not l10n---please wait)
+   continues.
+
+ * The scripting part of the codebase is getting prepared for i18n/l10n.
+
+ * Pushing and pulling from a repository with large number of refs that
+   point to identical commits are optimized by not listing the same commit
+   during the common ancestor negotiation exchange with the other side.
+
+ * Adding a file larger than core.bigfilethreshold (defaults to 1/2 Gig)
+   using "git add" will send the contents straight to a packfile without
+   having to hold it and its compressed representation both at the same
+   time in memory.
+
+ * Processes spawned by "[alias] <name> = !process" in the configuration
+   can inspect GIT_PREFIX environment variable to learn where in the
+   working tree the original command was invoked.
+
+ * A magic pathspec ":/" tells a command that limits its operation to
+   the current directory when ran from a subdirectory to work on the
+   entire working tree. In general, ":/path/to/file" would be relative
+   to the root of the working tree hierarchy.
+
+   After "git reset --hard; edit Makefile; cd t/", "git add -u" would
+   be a no-op, but "git add -u :/" would add the updated contents of
+   the Makefile at the top level. If you want to name a path in the
+   current subdirectory whose unusual name begins with ":/", you can
+   name it by "./:/that/path" or by "\:/that/path".
+
+ * "git blame" learned "--abbrev[=<n>]" option to control the minimum
+   number of hexdigits shown for commit object names.
+
+ * "git blame" learned "--line-porcelain" that is less efficient but is
+   easier to parse.
+
+ * Aborting "git commit --interactive" discards updates to the index
+   made during the interactive session.
+
+ * "git commit" learned a "--patch" option to directly jump to the
+   per-hunk selection UI of the interactive mode.
+
+ * "git diff" and its family of commands learned --dirstat=0 to show
+   directories that contribute less than 0.1% of changes.
+
+ * "git diff" and its family of commands learned --dirstat=lines mode to
+   assess damage to the directory based on number of lines in the patch
+   output, not based on the similarity numbers.
+
+ * "git format-patch" learned "--quiet" option to suppress the output of
+   the names of generated files.
+
+ * "git format-patch" quotes people's names when it has RFC822 special
+   characters in it, e.g. "Junio C. Hamano" <jch@example.com>.  Earlier
+   it was up to the user to do this when using its output.
+
+ * "git format-patch" can take an empty --subject-prefix now.
+
+ * "git grep" learned the "-P" option to take pcre regular expressions.
+
+ * "git log" and friends learned a new "--notes" option to replace the
+   "--show-notes" option.  Unlike "--show-notes", "--notes=<ref>" does
+   not imply showing the default notes.
+
+ * They also learned a log.abbrevCommit configuration variable to augment
+   the --abbrev-commit command line option.
+
+ * "git ls-remote" learned "--exit-code" option to consider it a
+   different kind of error when no remote ref to be shown.
+
+ * "git merge" learned "-" as a short-hand for "the previous branch", just
+   like the way "git checkout -" works.
+
+ * "git merge" uses "merge.ff" configuration variable to decide to always
+   create a merge commit (i.e. --no-ff, aka merge.ff=no), refuse to create
+   a merge commit (i.e. --ff-only, aka merge.ff=only). Setting merge.ff=yes
+   (or not setting it at all) restores the default behaviour of allowing
+   fast-forward to happen when possible.
+
+ * p4-import (from contrib) learned a new option --preserve-user.
+
+ * "git read-tree -m" learned "--dry-run" option that reports if a merge
+   would fail without touching the index nor the working tree.
+
+ * "git rebase" that does not specify on top of which branch to rebase
+   the current branch now uses @{upstream} of the current branch.
+
+ * "git rebase" finished either normally or with --abort did not
+   update the reflog for HEAD to record the event to come back to
+   where it started from.
+
+ * "git remote add -t only-this-branch --mirror=fetch" is now allowed. Earlier
+   a fetch-mode mirror meant mirror everything, but now it only means refs are
+   not renamed.
+
+ * "git rev-list --count" used with "--cherry-mark" counts the cherry-picked
+   commits separately, producing more a useful output.
+
+ * "git submodule update" learned "--force" option to get rid of local
+   changes in submodules and replace them with the up-to-date version.
+
+ * "git status" and friends ignore .gitmodules file while the file is
+   still in a conflicted state during a merge, to avoid using information
+   that is not final and possibly corrupt with conflict markers.
+
+Also contains various documentation updates and minor miscellaneous
+changes.
+
+
+Fixes since v1.7.5
+------------------
+
+Unless otherwise noted, all the fixes in 1.7.5.X maintenance track are
+included in this release.
+
+ * "git config" used to choke with an insanely long line.
+   (merge ef/maint-strbuf-init later)
+
+ * "git diff --quiet" did not work well with --diff-filter.
+   (merge jk/diff-not-so-quick later)
+
+ * "git status -z" did not default to --porcelain output format.
+   (merge bc/maint-status-z-to-use-porcelain later)

+Git v1.7.7.1 Release Notes
+==========================
+
+Fixes since v1.7.7
+------------------
+
+ * On some BSD systems, adding +s bit on directories is detrimental
+   (it is not necessary on BSD to begin with). "git init --shared"
+   has been updated to take this into account without extra makefile
+   settings on platforms the Makefile knows about.
+
+ * After incorrectly written third-party tools store a tag object in
+   HEAD, git diagnosed it as a repository corruption and refused to
+   proceed in order to avoid spreading the damage. We now gracefully
+   recover from such a situation by pretending as if the commit that
+   is pointed at by the tag were in HEAD.
+
+ * "git apply --whitespace=error" did not bother to report the exact
+   line number in the patch that introduced new blank lines at the end
+   of the file.
+
+ * "git apply --index" did not check corrupted patch.
+
+ * "git checkout $tree $directory/" resurrected paths locally removed or
+   modified only in the working tree in $directory/ that did not appear
+   in $directory of the given $tree. They should have been kept intact.
+
+ * "git diff $tree $path" used to apply the pathspec at the output stage,
+   reading the whole tree, wasting resources.
+
+ * The code to check for updated submodules during a "git fetch" of the
+   superproject had an unnecessary quadratic loop.
+
+ * "git fetch" from a large bundle did not enable the progress output.
+
+ * When "git fsck --lost-and-found" found that an empty blob object in the
+   object store is unreachable, it incorrectly reported an error after
+   writing the lost blob out successfully.
+
+ * "git filter-branch" did not refresh the index before checking that the
+   working tree was clean.
+
+ * "git grep $tree" when run with multiple threads had an unsafe access to
+   the object database that should have been protected with mutex.
+
+ * The "--ancestry-path" option to "git log" and friends misbehaved in a
+   history with complex criss-cross merges and showed an uninteresting
+   side history as well.
+
+ * Test t1304 assumed LOGNAME is always set, which may not be true on
+   some systems.
+
+ * Tests with --valgrind failed to find "mergetool" scriptlets.
+
+ * "git patch-id" miscomputed the patch-id in a patch that has a line longer
+   than 1kB.
+
+ * When an "exec" insn failed after modifying the index and/or the working
+   tree during "rebase -i", we now check and warn that the changes need to
+   be cleaned up.

+Git v1.7.7.3 Release Notes
+==========================
+
+Fixes since v1.7.7.2
+--------------------
+
+ * Adjust the "quick-install-doc" procedures as preformatted
+   html/manpage are no longer in the source repository.
+
+ * The logic to optimize the locality of the data in a pack introduced in
+   1.7.7 was grossly inefficient.
+
+ * The logic to filter out forked projects in the project list in
+   "gitweb" was broken for some time.
+
+ * "git branch -m/-M" advertised to update RENAME_REF ref in the
+   commit log message that introduced the feature but not anywhere in
+   the documentation, and never did update such a ref anyway. This
+   undocumented misfeature that did not exist has been excised.

+==========================

+
+ * "git name-rev --all" tried to name all _objects_, naturally failing to

+Git v1.7.7 Release Notes
+========================
+
+Updates since v1.7.6
+--------------------
+
+ * The scripting part of the codebase is getting prepared for i18n/l10n.
+
+ * Interix, Cygwin and Minix ports got updated.
+
+ * Various updates to git-p4 (in contrib/), fast-import, and git-svn.
+
+ * Gitweb learned to read from /etc/gitweb-common.conf when it exists,
+   before reading from gitweb_config.perl or from /etc/gitweb.conf
+   (this last one is read only when per-repository gitweb_config.perl
+   does not exist).
+
+ * Various codepaths that invoked zlib deflate/inflate assumed that these
+   functions can compress or uncompress more than 4GB data in one call on
+   platforms with 64-bit long, which has been corrected.
+
+ * Git now recognizes loose objects written by other implementations that
+   use a non-standard window size for zlib deflation (e.g. Agit running on
+   Android with 4kb window). We used to reject anything that was not
+   deflated with 32kb window.
+
+ * Interaction between the use of pager and coloring of the output has
+   been improved, especially when a command that is not built-in was
+   involved.
+
+ * "git am" learned to pass the "--exclude=<path>" option through to underlying
+   "git apply".
+
+ * You can now feed many empty lines before feeding an mbox file to
+   "git am".
+
+ * "git archive" can be told to pass the output to gzip compression and
+   produce "archive.tar.gz".
+
+ * "git bisect" can be used in a bare repository (provided that the test
+   you perform per each iteration does not need a working tree, of
+   course).
+
+ * The length of abbreviated object names in "git branch -v" output
+   now honors the core.abbrev configuration variable.
+
+ * "git check-attr" can take relative paths from the command line.
+
+ * "git check-attr" learned an "--all" option to list the attributes for a
+   given path.
+
+ * "git checkout" (both the code to update the files upon checking out a
+   different branch and the code to checkout a specific set of files) learned
+   to stream the data from object store when possible, without having to
+   read the entire contents of a file into memory first. An earlier round
+   of this code that is not in any released version had a large leak but
+   now it has been plugged.
+
+ * "git clone" can now take a "--config key=value" option to set the
+   repository configuration options that affect the initial checkout.
+
+ * "git commit <paths>..." now lets you feed relative pathspecs that
+   refer to outside your current subdirectory.
+
+ * "git diff --stat" learned a --stat-count option to limit the output of
+   a diffstat report.
+
+ * "git diff" learned a "--histogram" option to use a different diff
+   generation machinery stolen from jgit, which might give better
+   performance.
+
+ * "git diff" had a weird worst case behaviour that can be triggered
+   when comparing files with potentially many places that could match.
+
+ * "git fetch", "git push" and friends no longer show connection
+   errors for addresses that couldn't be connected to when at least one
+   address succeeds (this is arguably a regression but a deliberate
+   one).
+
+ * "git grep" learned "--break" and "--heading" options, to let users mimic
+   the output format of "ack".
+
+ * "git grep" learned a "-W" option that shows wider context using the same
+   logic used by "git diff" to determine the hunk header.
+
+ * Invoking the low-level "git http-fetch" without "-a" option (which
+   git itself never did---normal users should not have to worry about
+   this) is now deprecated.
+
+ * The "--decorate" option to "git log" and its family learned to
+   highlight grafted and replaced commits.
+
+ * "git rebase master topci" no longer spews usage hints after giving
+   the "fatal: no such branch: topci" error message.
+
+ * The recursive merge strategy implementation got a fairly large
+   fix for many corner cases that may rarely happen in real world
+   projects (it has been verified that none of the 16000+ merges in
+   the Linux kernel history back to v2.6.12 is affected with the
+   corner case bugs this update fixes).
+
+ * "git stash" learned an "--include-untracked option".
+
+ * "git submodule update" used to stop at the first error updating a
+   submodule; it now goes on to update other submodules that can be
+   updated, and reports the ones with errors at the end.
+
+ * "git push" can be told with the "--recurse-submodules=check" option to
+   refuse pushing of the supermodule, if any of its submodules'
+   commits hasn't been pushed out to their remotes.
+
+ * "git upload-pack" and "git receive-pack" learned to pretend that only a
+   subset of the refs exist in a repository. This may help a site to
+   put many tiny repositories into one repository (this would not be
+   useful for larger repositories as repacking would be problematic).
+
+ * "git verify-pack" has been rewritten to use the "index-pack" machinery
+   that is more efficient in reading objects in packfiles.
+
+ * test scripts for gitweb tried to run even when CGI-related perl modules
+   are not installed; they now exit early when the latter are unavailable.
+
+Also contains various documentation updates and minor miscellaneous
+changes.
+
+
+Fixes since v1.7.6
+------------------
+
+Unless otherwise noted, all fixes in the 1.7.6.X maintenance track are
+included in this release.
+
+ * "git branch -m" and "git checkout -b" incorrectly allowed the tip
+   of the branch that is currently checked out updated.

+Git v1.7.8.1 Release Notes
+==========================
+
+Fixes since v1.7.8
+------------------
+
+ * In some codepaths (notably, checkout and merge), the ignore patterns
+   recorded in $GIT_DIR/info/exclude were not honored. They now are.
+
+ * "git apply --check" did not error out when given an empty input
+   without any patch.
+
+ * "git archive" mistakenly allowed remote clients to ask for commits
+   that are not at the tip of any ref.
+
+ * "git checkout" and "git merge" treated in-tree .gitignore and exclude
+   file in $GIT_DIR/info/ directory inconsistently when deciding which
+   untracked files are ignored and expendable.
+
+ * LF-to-CRLF streaming filter used when checking out a large-ish blob
+   fell into an infinite loop with a rare input.
+
+ * The function header pattern for files with "diff=cpp" attribute did
+   not consider "type *funcname(type param1,..." as the beginning of a
+   function.
+
+ * The error message from "git diff" and "git status" when they fail
+   to inspect changes in submodules did not report which submodule they
+   had trouble with.
+
+ * After fetching from a remote that has very long refname, the reporting
+   output could have corrupted by overrunning a static buffer.
+
+ * "git pack-objects" avoids creating cyclic dependencies among deltas
+   when seeing a broken packfile that records the same object in both
+   the deflated form and as a delta.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.8.2 Release Notes
+==========================
+
+Fixes since v1.7.8.1
+--------------------
+
+ * Porcelain commands like "git reset" did not distinguish deletions
+   and type-changes from ordinary modification, and reported them with
+   the same 'M' moniker. They now use 'D' (for deletion) and 'T' (for
+   type-change) to match "git status -s" and "git diff --name-status".
+
+ * The configuration file parser used for sizes (e.g. bigFileThreshold)
+   did not correctly interpret 'g' suffix.
+
+ * The replacement implementation for snprintf used on platforms with
+   native snprintf that is broken did not use va_copy correctly.
+
+ * LF-to-CRLF streaming filter replaced all LF with CRLF, which might
+   be technically correct but not friendly to people who are trying
+   to recover from earlier mistakes of using CRLF in the repository
+   data in the first place. It now refrains from doing so for LF that
+   follows a CR.
+
+ * git native connection going over TCP (not over SSH) did not set
+   SO_KEEPALIVE option which failed to receive link layer errors.
+
+ * "git branch -m <current branch> HEAD" is an obvious no-op but was not
+   allowed.
+
+ * "git checkout -m" did not recreate the conflicted state in a "both
+   sides added, without any common ancestor version" conflict
+   situation.
+
+ * "git cherry-pick $commit" (not a range) created an unnecessary
+   sequencer state and interfered with valid workflow to use the
+   command during a session to cherry-pick multiple commits.
+
+ * You could make "git commit" segfault by giving the "--no-message"
+   option.
+
+ * "fast-import" did not correctly update an existing notes tree,
+   possibly corrupting the fan-out.
+
+ * "git fetch-pack" accepted unqualified refs that do not begin with
+   refs/ by mistake and compensated it by matching the refspec with
+   tail-match, which was doubly wrong. This broke fetching from a
+   repository with a funny named ref "refs/foo/refs/heads/master" and a
+   'master' branch with "git fetch-pack refs/heads/master", as the
+   command incorrectly considered the former a "match".
+
+ * "git log --follow" did not honor the rename threshold score given
+   with the -M option (e.g. "-M50%").
+
+ * "git mv" gave suboptimal error/warning messages when it overwrites
+   target files. It also did not pay attention to "-v" option.
+
+ * Authenticated "git push" over dumb HTTP were broken with a recent
+   change and failed without asking for password when username is
+   given.
+
+ * "git push" to an empty repository over HTTP were broken with a
+   recent change to the ref handling.
+
+ * "git push -v" forgot how to be verbose by mistake. It now properly
+   becomes verbose when asked to.
+
+ * When a "reword" action in "git rebase -i" failed to run "commit --amend",
+   we did not give the control back to the user to resolve the situation, and
+   instead kept the original commit log message.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.8 Release Notes
+========================
+
+Updates since v1.7.7
+--------------------
+
+ * Some git-svn, git-gui, git-p4 (in contrib) and msysgit updates.
+
+ * Updates to bash completion scripts.
+
+ * The build procedure has been taught to take advantage of computed
+   dependency automatically when the compiler supports it.
+
+ * The date parser now accepts timezone designators that lack minutes
+   part and also has a colon between "hh:mm".
+
+ * The contents of the /etc/mailname file, if exists, is used as the
+   default value of the hostname part of the committer/author e-mail.
+
+ * "git am" learned how to read from patches generated by Hg.
+
+ * "git archive" talking with a remote repository can report errors
+   from the remote side in a more informative way.
+
+ * "git branch" learned an explicit --list option to ask for branches
+   listed, optionally with a glob matching pattern to limit its output.
+
+ * "git check-attr" learned "--cached" option to look at .gitattributes
+   files from the index, not from the working tree.
+
+ * Variants of "git cherry-pick" and "git revert" that take multiple
+   commits learned to "--continue" and "--abort".
+
+ * "git daemon" gives more human readable error messages to clients
+   using ERR packets when appropriate.
+
+ * Errors at the network layer is logged by "git daemon".
+
+ * "git diff" learned "--minimal" option to spend extra cycles to come
+   up with a minimal patch output.
+
+ * "git diff" learned "--function-context" option to show the whole
+   function as context that was affected by a change.
+
+ * "git difftool" can be told to skip launching the tool for a path by
+   answering 'n' to its prompt.
+
+ * "git fetch" learned to honor transfer.fsckobjects configuration to
+   validate the objects that were received from the other end, just like
+   "git receive-pack" (the receiving end of "git push") does.
+
+ * "git fetch" makes sure that the set of objects it received from the
+   other end actually completes the history before updating the refs.
+   "git receive-pack" (the receiving end of "git push") learned to do the
+   same.
+
+ * "git fetch" learned that fetching/cloning from a regular file on the
+   filesystem is not necessarily a request to unpack a bundle file; the
+   file could be ".git" with "gitdir: <path>" in it.
+
+ * "git for-each-ref" learned "%(contents:subject)", "%(contents:body)"
+   and "%(contents:signature)". The last one is useful for signed tags.
+
+ * "git grep" used to incorrectly pay attention to .gitignore files
+   scattered in the directory it was working in even when "--no-index"
+   option was used. It no longer does this. The "--exclude-standard"
+   option needs to be given to explicitly activate the ignore
+   mechanism.
+
+ * "git grep" learned "--untracked" option, where given patterns are
+    searched in untracked (but not ignored) files as well as tracked
+    files in the working tree, so that matches in new but not yet
+    added files do not get missed.
+
+ * The recursive merge backend no longer looks for meaningless
+   existing merges in submodules unless in the outermost merge.
+
+ * "git log" and friends learned "--children" option.
+
+ * "git ls-remote" learned to respond to "-h"(elp) requests.
+
+ * "mediawiki" remote helper can interact with (surprise!) MediaWiki
+   with "git fetch" & "git push".
+
+ * "git merge" learned the "--edit" option to allow users to edit the
+   merge commit log message.
+
+ * "git rebase -i" can be told to use special purpose editor suitable
+   only for its insn sheet via sequence.editor configuration variable.
+
+ * "git send-email" learned to respond to "-h"(elp) requests.
+
+ * "git send-email" allows the value given to sendemail.aliasfile to begin
+   with "~/" to refer to the $HOME directory.
+
+ * "git send-email" forces use of Authen::SASL::Perl to work around
+   issues between Authen::SASL::Cyrus and AUTH PLAIN/LOGIN.
+
+ * "git stash" learned "--include-untracked" option to stash away
+   untracked/ignored cruft from the working tree.
+
+ * "git submodule clone" does not leak an error message to the UI
+   level unnecessarily anymore.
+
+ * "git submodule update" learned to honor "none" as the value for
+   submodule.<name>.update to specify that the named submodule should
+   not be checked out by default.
+
+ * When populating a new submodule directory with "git submodule init",
+   the $GIT_DIR metainformation directory for submodules is created inside
+   $GIT_DIR/modules/<name>/ directory of the superproject and referenced
+   via the gitfile mechanism. This is to make it possible to switch
+   between commits in the superproject that has and does not have the
+   submodule in the tree without re-cloning.
+
+ * "gitweb" leaked unescaped control characters from syntax hiliter
+   outputs.
+
+ * "gitweb" can be told to give custom string at the end of the HTML
+   HEAD element.
+
+ * "gitweb" now has its own manual pages.
+
+
+Also contains other documentation updates and minor code cleanups.
+
+
+Fixes since v1.7.7
+------------------
+
+Unless otherwise noted, all fixes in the 1.7.7.X maintenance track are
+included in this release.
+
+ * HTTP transport did not use pushurl correctly, and also did not tell
+   what host it is trying to authenticate with when asking for
+   credentials.
+   (merge deba493 jk/http-auth later to maint).
+
+ * "git blame" was aborted if started from an uncommitted content and
+   the path had the textconv filter in effect.
+   (merge 8518088 ss/blame-textconv-fake-working-tree later to maint).
+
+ * Adding many refs to the local repository in one go (e.g. "git fetch"
+   that fetches many tags) and looking up a ref by name in a repository
+   with too many refs were unnecessarily slow.
+   (merge 17d68a54d jp/get-ref-dir-unsorted later to maint).
+
+ * Report from "git commit" on untracked files was confused under
+   core.ignorecase option.
+   (merge 395c7356 jk/name-hash-dirent later to maint).
+

+Git v1.7.9.1 Release Notes
+==========================
+
+Fixes since v1.7.9
+------------------
+
+ * The makefile allowed environment variable X seep into it result in
+   command names suffixed with unnecessary strings.
+
+ * The set of included header files in compat/inet-{ntop,pton}
+   wrappers was updated for Windows some time ago, but in a way that
+   broke Solaris build.
+
+ * rpmbuild noticed an unpackaged but installed *.mo file and failed.
+
+ * Subprocesses spawned from various git programs were often left running
+   to completion even when the top-level process was killed.
+
+ * "git add -e" learned not to show a diff for an otherwise unmodified
+   submodule that only has uncommitted local changes in the patch
+   prepared by for the user to edit.
+
+ * Typo in "git branch --edit-description my-tpoic" was not diagnosed.
+
+ * Using "git grep -l/-L" together with options -W or --break may not
+   make much sense as the output is to only count the number of hits
+   and there is no place for file breaks, but the latter options made
+   "-l/-L" to miscount the hits.
+
+ * "git log --first-parent $pathspec" did not stay on the first parent
+   chain and veered into side branch from which the whole change to the
+   specified paths came.
+
+ * "git merge --no-edit $tag" failed to honor the --no-edit option.
+
+ * "git merge --ff-only $tag" failed because it cannot record the
+   required mergetag without creating a merge, but this is so common
+   operation for branch that is used _only_ to follow the upstream, so
+   it was changed to allow fast-forwarding without recording the mergetag.
+
+ * "git mergetool" now gives an empty file as the common base version
+   to the backend when dealing with the "both sides added, differently"
+   case.
+
+ * "git push -q" was not sufficiently quiet.
+
+ * When "git push" fails to update any refs, the client side did not
+   report an error correctly to the end user.
+
+ * "rebase" and "commit --amend" failed to work on commits with ancient
+   timestamps near year 1970.
+
+ * When asking for a tag to be pulled, "request-pull" did not show the
+   name of the tag prefixed with "tags/", which would have helped older
+   clients.
+
+ * "git submodule add $path" forgot to recompute the name to be stored
+   in .gitmodules when the submodule at $path was once added to the
+   superproject and already initialized.
+
+ * Many small corner case bugs on "git tag -n" was corrected.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.9.2 Release Notes
+==========================
+
+Fixes since v1.7.9.1
+--------------------
+
+ * Bash completion script (in contrib/) did not like a pattern that
+   begins with a dash to be passed to __git_ps1 helper function.
+
+ * Adaptation of the bash completion script (in contrib/) for zsh
+   incorrectly listed all subcommands when "git <TAB><TAB>" was given
+   to ask for list of porcelain subcommands.
+
+ * The build procedure for profile-directed optimized binary was not
+   working very well.
+
+ * Some systems need to explicitly link -lcharset to get locale_charset().
+
+ * t5541 ignored user-supplied port number used for HTTP server testing.
+
+ * The error message emitted when we see an empty loose object was
+   not phrased correctly.
+
+ * The code to ask for password did not fall back to the terminal
+   input when GIT_ASKPASS is set but does not work (e.g. lack of X
+   with GUI askpass helper).
+
+ * We failed to give the true terminal width to any subcommand when
+   they are invoked with the pager, i.e. "git -p cmd".
+
+ * map_user() was not rewriting its output correctly, which resulted
+   in the user visible symptom that "git blame -e" sometimes showed
+   excess '>' at the end of email addresses.
+
+ * "git checkout -b" did not allow switching out of an unborn branch.
+
+ * When you have both .../foo and .../foo.git, "git clone .../foo" did not
+   favor the former but the latter.
+
+ * "git commit" refused to create a commit when entries added with
+   "add -N" remained in the index, without telling Git what their content
+   in the next commit should be. We should have created the commit without
+   these paths.
+
+ * "git diff --stat" said "files", "insertions", and "deletions" even
+   when it is showing one "file", one "insertion" or one "deletion".
+
+ * The output from "git diff --stat" for two paths that have the same
+   amount of changes showed graph bars of different length due to the
+   way we handled rounding errors.
+
+ * "git grep" did not pay attention to -diff (hence -binary) attribute.
+
+ * The transport programs (fetch, push, clone)ignored --no-progress
+   and showed progress when sending their output to a terminal.
+
+ * Sometimes error status detected by a check in an earlier phase of
+   "git receive-pack" (the other end of "git push") was lost by later
+   checks, resulting in false indication of success.
+
+ * "git rev-list --verify" sometimes skipped verification depending on
+   the phase of the moon, which dates back to 1.7.8.x series.
+
+ * Search box in "gitweb" did not accept non-ASCII characters correctly.
+
+ * Search interface of "gitweb" did not show multiple matches in the same file
+   correctly.
+
+Also contains minor fixes and documentation updates.

+==========================
+
+Fixes since v1.7.9.2
+--------------------
+
+ * "git p4" (in contrib/) submit the changes to a wrong place when the
+   "--use-client-spec" option is set.
+
+ * The config.mak.autogen generated by optional autoconf support tried
+   to link the binary with -lintl even when libintl.h is missing from
+   the system.
+
+ * When the filter driver exits before reading the content before the
+   main git process writes the contents to be filtered to the pipe to
+   it, the latter could be killed with SIGPIPE instead of ignoring
+   such an event as an error.
+
+ * "git add --refresh <pathspec>" used to warn about unmerged paths
+   outside the given pathspec.
+
+ * The bulk check-in codepath in "git add" streamed contents that
+   needs smudge/clean filters without running them, instead of punting
+   and delegating to the codepath to run filters after slurping
+   everything to core.
+
+ * "git branch --with $that" assumed incorrectly that the user will never
+   ask the question with nonsense value in $that.
+
+ * "git bundle create" produced a corrupt bundle file upon seeing
+   commits with excessively long subject line.
+
+ * When a remote helper exits before reading the blank line from the
+   main git process to signal the end of commands, the latter could be
+   killed with SIGPIPE. Instead we should ignore such event as a
+   non-error.
+
+ * The commit log template given with "git merge --edit" did not have
+   a short instructive text like what "git commit" gives.
+
+ * "git rev-list --verify-objects -q" omitted the extra verification
+   it needs to do over "git rev-list --objects -q" by mistake.
+
+ * "gitweb" used to drop warnings in the log file when "heads" view is
+   accessed in a repository whose HEAD does not point at a valid
+   branch.
+
+ * An invalid regular expression pattern given by an end user made
+   "gitweb" to return garbled response.
+
+Also contains minor fixes and documentation updates.

+
+ * "git bundle" did not record boundary commits correctly when there

+Git v1.7.9 Release Notes
+========================
+
+Updates since v1.7.8
+--------------------
+
+ * gitk updates accumulated since early 2011.
+
+ * git-gui updated to 0.16.0.
+
+ * git-p4 (in contrib/) updates.
+
+ * Git uses gettext to translate its most common interface messages
+   into the user's language if translations are available and the
+   locale is appropriately set. Distributors can drop new PO files
+   in po/ to add new translations.
+
+ * The code to handle username/password for HTTP transactions used in
+   "git push" & "git fetch" learned to talk "credential API" to
+   external programs to cache or store them, to allow integration with
+   platform native keychain mechanisms.
+
+ * The input prompts in the terminal use our own getpass() replacement
+   when possible. HTTP transactions used to ask for the username without
+   echoing back what was typed, but with this change you will see it as
+   you type.
+
+ * The internals of "revert/cherry-pick" have been tweaked to prepare
+   building more generic "sequencer" on top of the implementation that
+   drives them.
+
+ * "git rev-parse FETCH_HEAD" after "git fetch" without specifying
+   what to fetch from the command line will now show the commit that
+   would be merged if the command were "git pull".
+
+ * "git add" learned to stream large files directly into a packfile
+   instead of writing them into individual loose object files.
+
+ * "git checkout -B <current branch> <elsewhere>" is a more intuitive
+   way to spell "git reset --keep <elsewhere>".
+
+ * "git checkout" and "git merge" learned "--no-overwrite-ignore" option
+   to tell Git that untracked and ignored files are not expendable.
+
+ * "git commit --amend" learned "--no-edit" option to say that the
+   user is amending the tree being recorded, without updating the
+   commit log message.
+
+ * "git commit" and "git reset" re-learned the optimization to prime
+   the cache-tree information in the index, which makes it faster to
+   write a tree object out after the index entries are updated.
+
+ * "git commit" detects and rejects an attempt to stuff NUL byte in
+   the commit log message.
+
+ * "git commit" learned "-S" to GPG-sign the commit; this can be shown
+   with the "--show-signature" option to "git log".
+
+ * fsck and prune are relatively lengthy operations that still go
+   silent while making the end-user wait. They learned to give progress
+   output like other slow operations.
+
+ * The set of built-in function-header patterns for various languages
+   knows MATLAB.
+
+ * "git log --format='<format>'" learned new %g[nNeE] specifiers to
+   show information from the reflog entries when walking the reflog
+   (i.e. with "-g").
+
+ * "git pull" can be used to fetch and merge an annotated/signed tag,
+   instead of the tip of a topic branch. The GPG signature from the
+   signed tag is recorded in the resulting merge commit for later
+   auditing.
+
+ * "git log" learned "--show-signature" option to show the signed tag
+   that was merged that is embedded in the merge commit. It also can
+   show the signature made on the commit with "git commit -S".
+
+ * "git branch --edit-description" can be used to add descriptive text
+   to explain what a topic branch is about.
+
+ * "git fmt-merge-msg" learned to take the branch description into
+   account when preparing a merge summary that "git merge" records
+   when merging a local branch.
+
+ * "git request-pull" has been updated to convey more information
+   useful for integrators to decide if a topic is worth merging and
+   what is pulled is indeed what the requestor asked to pull,
+   including:
+
+   - the tip of the branch being requested to be merged;
+   - the branch description describing what the topic is about;
+   - the contents of the annotated tag, when requesting to pull a tag.
+
+ * "git pull" learned to notice 'pull.rebase' configuration variable,
+   which serves as a global fallback for setting 'branch.<name>.rebase'
+   configuration variable per branch.
+
+ * "git tag" learned "--cleanup" option to control how the whitespaces
+   and empty lines in tag message are cleaned up.
+
+ * "gitweb" learned to show side-by-side diff.
+
+Also contains minor documentation updates and code clean-ups.

+------------------
+
+ * The configuration parser had an unnecessary hardcoded limit on
+   variable names that was not checked consistently.
+
+ * The "say" function in the test scaffolding incorrectly allowed
+   "echo" to interpret "\a" as if it were a C-string asking for a
+   BEL output.
+
+ * "git mergetool" feeds /dev/null as a common ancestor when dealing
+   with an add/add conflict, but p4merge backend cannot handle
+   it. Work it around by passing a temporary empty file.
+
+ * "git log -F -E --grep='<ere>'" failed to use the given <ere>
+   pattern as extended regular expression, and instead looked for the
+   string literally.
+
+ * "git grep -e pattern <tree>" asked the attribute system to read
+   "<tree>:.gitattributes" file in the working tree, which was
+   nonsense.
+
+ * A symbolic ref refs/heads/SYM was not correctly removed with "git
+   branch -d SYM"; the command removed the ref pointed by SYM
+   instead.
+
+ * Earlier we fixed documentation to hyphenate "remote-tracking branch"
+   to clarify that these are not a remote entity, but unhyphenated
+   spelling snuck in to a few places since then.
+
+ * "git pull --rebase" run while the HEAD is detached tried to find
+   the upstream branch of the detached HEAD (which by definition
+   does not exist) and emitted unnecessary error messages.
+
+ * The refs/replace hierarchy was not mentioned in the
+   repository-layout docs.
+
+ * Sometimes curl_multi_timeout() function suggested a wrong timeout
+   value when there is no file descriptors to wait on and the http
+   transport ended up sleeping for minutes in select(2) system call.
+   A workaround has been added for this.
+
+ * Various rfc2047 quoting issues around a non-ASCII name on the
+   From: line in the output from format-patch have been corrected.
+
+ * "git diff -G<pattern>" did not honor textconv filter when looking
+   for changes.
+
+ * Bash completion script (in contrib/) did not correctly complete a

+   command line.
+
+ * RSS feed from "gitweb" had a xss hole in its title output.
+
+ * "git config --path $key" segfaulted on "[section] key" (a boolean

+
+ * "git checkout -b foo" while on an unborn branch did not say

+Git v1.8.0 Release Notes
+========================
+
+Backward compatibility notes
+----------------------------
+
+In the next major release (not *this* one), we will change the
+behavior of the "git push" command.
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  We will use the "simple" semantics that pushes the
+current branch to the branch with the same name, only when the current
+branch is set to integrate with that remote branch.  There is a user
+preference configuration variable "push.default" to change this, and
+"git push" will warn about the upcoming change until you set this
+variable in this release.
+
+"git branch --set-upstream" is deprecated and may be removed in a
+relatively distant future.  "git branch [-u|--set-upstream-to]" has
+been introduced with a saner order of arguments.
+
+
+Updates since v1.7.12
+---------------------
+
+UI, Workflows & Features
+
+ * A credential helper for Win32 to allow access to the keychain of
+   the logged-in user has been added.
+
+ * An initial port to HP NonStop.
+
+ * A credential helper to allow access to the Gnome keyring has been
+   added.
+
+ * When "git am" sanitizes the "Subject:" line, we strip the prefix from
+   "Re: subject" and also from a less common "re: subject", but left
+   the even less common "RE: subject" intact.  Now we strip that too.
+
+ * It was tempting to say "git branch --set-upstream origin/master",
+   but that tells Git to arrange the local branch "origin/master" to
+   integrate with the currently checked out branch, which is highly
+   unlikely what the user meant.  The option is deprecated; use the
+   new "--set-upstream-to" (with a short-and-sweet "-u") option
+   instead.
+
+ * "git cherry-pick" learned the "--allow-empty-message" option to
+   allow it to replay a commit without any log message.
+
+ * After "git cherry-pick -s" gave control back to the user asking
+   help to resolve conflicts, concluding "git commit" used to need to
+   be run with "-s" if the user wants to sign it off; now the command
+   leaves the sign-off line in the log template.
+
+ * "git daemon" learned the "--access-hook" option to allow an
+   external command to decline service based on the client address,
+   repository path, etc.
+
+ * "git difftool --dir-diff" learned to use symbolic links to prepare
+   a temporary copy of the working tree when available.
+
+ * "git grep" learned to use a non-standard pattern type by default if
+   a configuration variable tells it to.
+
+ * Accumulated updates to "git gui" has been merged.
+
+ * "git log -g" learned the "--grep-reflog=<pattern>" option to limit
+   its output to commits with a reflog message that matches the given
+   pattern.
+
+ * "git merge-base" learned the "--is-ancestor A B" option to tell if A is
+   an ancestor of B.  The result is indicated by its exit status code.
+
+ * "git mergetool" now allows users to override the actual command used
+   with the mergetool.$name.cmd configuration variable even for built-in
+   mergetool backends.
+
+ * "git rebase -i" learned the "--edit-todo" option to open an editor
+   to edit the instruction sheet.
+
+
+Foreign Interface
+
+ * "git svn" has been updated to work with SVN 1.7.
+
+ * "git p4" learned the "--conflicts" option to specify what to do when
+   encountering a conflict during "p4 submit".
+
+
+Performance, Internal Implementation, etc.
+
+ * Git ships with a fall-back regexp implementation for platforms with
+   buggy regexp library, but it was easy for people to keep using their
+   platform regexp by mistake.  A new test has been added to check this.
+
+ * The "check-docs" build target has been updated and greatly
+   simplified.
+
+ * The test suite is run under MALLOC_CHECK_ when running with a glibc
+   that supports the feature.
+
+ * The documentation in the TeXinfo format was using indented output
+   for materials meant to be examples that are better typeset in
+   monospace.
+
+ * Compatibility wrapper around some mkdir(2) implementations that
+   reject parameters with trailing slash has been introduced.
+
+ * Compatibility wrapper for systems that lack usable setitimer() has
+   been added.
+
+ * The option parsing of "git checkout" had error checking, dwim and
+   defaulting missing options, all mixed in the code, and issuing an
+   appropriate error message with useful context was getting harder.
+   The code has been reorganized to allow giving a proper diagnosis
+   when the user says "git checkout -b -t foo bar" (e.g. "-t" is not a
+   good name for a branch).
+
+ * Many internal uses of a "git merge-base" equivalent were only to see
+   if one commit fast-forwards to the other, which did not need the
+   full set of merge bases to be computed. They have been updated to
+   use less expensive checks.
+
+ * The heuristics to detect and silently convert latin1 to utf8 when
+   we were told to use utf-8 in the log message has been transplanted
+   from "mailinfo" to "commit" and "commit-tree".
+
+ * Messages given by "git <subcommand> -h" from many subcommands have
+   been marked for translation.
+
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.7.12
+-------------------
+
+Unless otherwise noted, all the fixes since v1.7.12 in the
+maintenance track are contained in this release (see release notes
+to them for details).
+
+ * The attribute system may be asked for a path that itself or its
+   leading directories no longer exists in the working tree, and it is
+   fine if we cannot open .gitattribute file in such a case.  Failure
+   to open per-directory .gitattributes with error status other than
+   ENOENT and ENOTDIR should be diagnosed, but it wasn't.
+
+ * When looking for $HOME/.gitconfig etc., it is OK if we cannot read
+   them because they do not exist, but we did not diagnose existing
+   files that we cannot read.
+
+ * When "git am" is fed an input that has multiple "Content-type: ..."
+   header, it did not grok charset= attribute correctly.
+
+ * "git am" mishandled a patch attached as application/octet-stream
+   (e.g. not text/*); Content-Transfer-Encoding (e.g. base64) was not
+   honored correctly.
+
+ * "git blame MAKEFILE" run in a history that has "Makefile" but not
+   "MAKEFILE" should say "No such file MAKEFILE in HEAD", but got
+   confused on a case insensitive filesystem and failed to do so.
+
+ * Even during a conflicted merge, "git blame $path" always meant to
+   blame uncommitted changes to the "working tree" version; make it
+   more useful by showing cleanly merged parts as coming from the other
+   branch that is being merged.
+
+ * It was unclear in the documentation for "git blame" that it is
+   unnecessary for users to use the "--follow" option.
+
+ * Output from "git branch -v" contains "(no branch)" that could be
+   localized, but the code to align it along with the names of
+   branches was counting in bytes, not in display columns.
+
+ * "git cherry-pick A C B" used to replay changes in A and then B and
+   then C if these three commits had committer timestamps in that
+   order, which is not what the user who said "A C B" naturally
+   expects.
+
+ * A repository created with "git clone --single" had its fetch
+   refspecs set up just like a clone without "--single", leading the
+   subsequent "git fetch" to slurp all the other branches, defeating
+   the whole point of specifying "only this branch".
+
+ * Documentation talked about "first line of commit log" when it meant
+   the title of the commit.  The description was clarified by defining
+   how the title is decided and rewording the casual mention of "first
+   line" to "title".
+
+ * "git cvsimport" did not thoroughly cleanse tag names that it
+   inferred from the names of the tags it obtained from CVS, which
+   caused "git tag" to barf and stop the import in the middle.
+
+ * Earlier we made the diffstat summary line that shows the number of
+   lines added/deleted localizable, but it was found irritating having
+   to see them in various languages on a list whose discussion language
+   is English, and this change has been reverted.
+
+ * "git fetch --all", when passed "--no-tags", did not honor the
+   "--no-tags" option while fetching from individual remotes (the same
+   issue existed with "--tags", but the combination "--all --tags" makes
+   much less sense than "--all --no-tags").
+
+ * "git fetch" over http had an old workaround for an unlikely server
+   misconfiguration; it turns out that this hurts debuggability of the
+   configuration in general, and has been reverted.
+
+ * "git fetch" over http advertised that it supports "deflate", which
+   is much less common, and did not advertise the more common "gzip" on
+   its Accept-Encoding header.
+
+ * "git fetch" over the dumb-http revision walker could segfault when
+   curl's multi interface was used.
+
+ * "git gc --auto" notified the user that auto-packing has triggered
+    even under the "--quiet" option.
+
+ * After "gitk" showed the contents of a tag, neither "Reread
+   references" nor "Reload" updated what is shown as the
+   contents of it when the user overwrote the tag with "git tag -f".
+
+ * "git log --all-match --grep=A --grep=B" ought to show commits that
+   mention both A and B, but when these three options are used with
+   --author or --committer, it showed commits that mention either A or
+   B (or both) instead.
+
+ * The "-Xours" backend option to "git merge -s recursive" was ignored
+   for binary files.
+
+ * "git p4", when "--use-client-spec" and "--detect-branches" are used
+   together, misdetected branches.
+
+ * "git receive-pack" (the counterpart to "git push") did not give
+   progress output while processing objects it received to the puser
+   when run over the smart-http protocol.
+
+ * When you misspell the command name you give to the "exec" action in
+   the "git rebase -i" instruction sheet you were told that 'rebase' is not a
+   git subcommand from "git rebase --continue".
+
+ * The subcommand in "git remote" to remove a defined remote was
+   "rm" and the command did not take a fully-spelled "remove".
+
+ * The interactive prompt that "git send-email" gives was error prone. It
+   asked "What e-mail address do you want to use?" with the address it
+   guessed (correctly) the user would want to use in its prompt,
+   tempting the user to say "y". But the response was taken as "No,
+   please use 'y' as the e-mail address instead", which is most
+   certainly not what the user meant.
+
+ * "git show --format='%ci'" did not give the timestamp correctly for
+   commits created without human readable name on the "committer" line.
+
+ * "git show --quiet" ought to be a synonym for "git show -s", but
+   wasn't.
+
+ * "git submodule frotz" was not diagnosed as "frotz" being an unknown
+   subcommand to "git submodule"; the user instead got a complaint
+   that "git submodule status" was run with an unknown path "frotz".
+
+ * "git status" honored the ignore=dirty settings in .gitmodules but
+   "git commit" didn't.
+
+ * "gitweb" did not give the correct committer timezone in its feed
+   output due to a typo.

+Git 1.8.1.1 Release Notes
+=========================
+
+Fixes since v1.8.1
+------------------
+
+ * The attribute mechanism didn't allow limiting attributes to be
+   applied to only a single directory itself with "path/" like the
+   exclude mechanism does.
+
+ * When attempting to read the XDG-style $HOME/.config/git/config and
+   finding that $HOME/.config/git is a file, we gave a wrong error
+   message, instead of treating the case as "a custom config file does
+   not exist there" and moving on.
+
+ * After failing to create a temporary file using mkstemp(), failing
+   pathname was not reported correctly on some platforms.
+
+ * http transport was wrong to ask for the username when the
+   authentication is done by certificate identity.
+
+ * The behaviour visible to the end users was confusing, when they
+   attempt to kill a process spawned in the editor that was in turn
+   launched by Git with SIGINT (or SIGQUIT), as Git would catch that
+   signal and die.  We ignore these signals now.
+
+ * A child process that was killed by a signal (e.g. SIGINT) was
+   reported in an inconsistent way depending on how the process was
+   spawned by us, with or without a shell in between.
+
+ * After "git add -N" and then writing a tree object out of the
+   index, the cache-tree data structure got corrupted.
+
+ * "git apply" misbehaved when fixing whitespace breakages by removing
+   excess trailing blank lines in some corner cases.
+
+ * A tar archive created by "git archive" recorded a directory in a
+   way that made NetBSD's implementation of "tar" sometimes unhappy.
+
+ * When "git clone --separate-git-dir=$over_there" is interrupted, it
+   failed to remove the real location of the $GIT_DIR it created.
+   This was most visible when interrupting a submodule update.
+
+ * "git fetch --mirror" and fetch that uses other forms of refspec
+   with wildcard used to attempt to update a symbolic ref that match
+   the wildcard on the receiving end, which made little sense (the
+   real ref that is pointed at by the symbolic ref would be updated
+   anyway).  Symbolic refs no longer are affected by such a fetch.
+
+ * The "log --graph" codepath fell into infinite loop in some
+   corner cases.
+
+ * "git merge" started calling prepare-commit-msg hook like "git
+   commit" does some time ago, but forgot to pay attention to the exit
+   status of the hook.
+
+ * "git pack-refs" that ran in parallel to another process that
+   created new refs had a race that can lose new ones.
+
+ * When a line to be wrapped has a solid run of non space characters
+   whose length exactly is the wrap width, "git shortlog -w" failed
+   to add a newline after such a line.
+
+ * The way "git svn" asked for password using SSH_ASKPASS and
+   GIT_ASKPASS was not in line with the rest of the system.
+
+ * "gitweb", when sorting by age to show repositories with new
+   activities first, used to sort repositories with absolutely
+   nothing in it early, which was not very useful.
+
+ * "gitweb", when sorting by age to show repositories with new
+   activities first, used to sort repositories with absolutely
+   nothing in it early, which was not very useful.
+
+ * When autoconf is used, any build on a different commit always ran
+   "config.status --recheck" even when unnecessary.
+
+ * Some scripted programs written in Python did not get updated when
+   PYTHON_PATH changed.
+
+ * We have been carrying a translated and long-unmaintained copy of an
+   old version of the tutorial; removed.
+
+ * Portability issues in many self-test scripts have been addressed.
+
+
+Also contains other minor fixes and documentation updates.

+Git 1.8.1.2 Release Notes
+=========================
+
+Fixes since v1.8.1.1
+--------------------
+
+ * An element on GIT_CEILING_DIRECTORIES list that does not name the
+   real path to a directory (i.e. a symbolic link) could have caused
+   the GIT_DIR discovery logic to escape the ceiling.
+
+ * Command line completion for "tcsh" emitted an unwanted space
+   after completing a single directory name.
+
+ * Command line completion leaked an unnecessary error message while
+   looking for possible matches with paths in <tree-ish>.
+
+ * "git archive" did not record uncompressed size in the header when
+   streaming a zip archive, which confused some implementations of unzip.
+
+ * When users spelled "cc:" in lowercase in the fake "header" in the
+   trailer part, "git send-email" failed to pick up the addresses from
+   there. As e-mail headers field names are case insensitive, this
+   script should follow suit and treat "cc:" and "Cc:" the same way.

+Git 1.8.1.3 Release Notes
+=========================
+
+Fixes since v1.8.1.2
+--------------------
+
+ * The attribute mechanism didn't allow limiting attributes to be
+   applied to only a single directory itself with "path/" like the
+   exclude mechanism does.  The fix for this in 1.8.1.2 had
+   performance degradations.
+
+ * Command line completion code was inadvertently made incompatible with
+   older versions of bash by using a newer array notation.
+
+ * Scripts to test bash completion was inherently flaky as it was
+   affected by whatever random things the user may have on $PATH.
+
+ * A fix was added to the build procedure to work around buggy
+   versions of ccache broke the auto-generation of dependencies, which
+   unfortunately is still relevant because some people use ancient
+   distros.
+
+ * We used to stuff "user@" and then append what we read from
+   /etc/mailname to come up with a default e-mail ident, but a bug
+   lost the "user@" part.
+
+ * "git am" did not parse datestamp correctly from Hg generated patch,
+   when it is run in a locale outside C (or en).
+
+ * Attempt to "branch --edit-description" an existing branch, while
+   being on a detached HEAD, errored out.
+
+ * "git cherry-pick" did not replay a root commit to an unborn branch.
+
+ * We forgot to close the file descriptor reading from "gpg" output,
+   killing "git log --show-signature" on a long history.
+
+ * "git rebase --preserve-merges" lost empty merges in recent versions
+   of Git.
+
+ * Rebasing the history of superproject with change in the submodule
+   has been broken since v1.7.12.
+
+ * A failure to push due to non-ff while on an unborn branch
+   dereferenced a NULL pointer when showing an error message.
+
+Also contains various documentation fixes.

+Git 1.8.1.5 Release Notes
+=========================
+
+Fixes since v1.8.1.4
+--------------------
+
+ * Given a string with a multi-byte character that begins with '-' on
+   the command line where an option is expected, the option parser
+   used just one byte of the unknown letter when reporting an error.
+
+ * In v1.8.1, the attribute parser was tightened too restrictive to
+   error out upon seeing an entry that begins with an ! (exclamation),
+   which may confuse users to expect a "negative match", which does
+   not exist.  This has been demoted to a warning; such an entry is
+   still ignored.
+
+ * "git apply --summary" has been taught to make sure the similarity
+   value shown in its output is sensible, even when the input had a
+   bogus value.
+
+ * "git clean" showed what it was going to do, but sometimes ended
+   up finding that it was not allowed to do so, which resulted in a
+   confusing output (e.g. after saying that it will remove an
+   untracked directory, it found an embedded git repository there
+   which it is not allowed to remove).  It now performs the actions
+   and then reports the outcome more faithfully.
+
+ * "git clone" used to allow --bare and --separate-git-dir=$there
+   options at the same time, which was nonsensical.
+
+ * "git cvsimport" mishandled timestamps at DST boundary.
+
+ * We used to have an arbitrary 32 limit for combined diff input,
+   resulting in incorrect number of leading colons shown when showing
+   the "--raw --cc" output.
+
+ * The smart HTTP clients forgot to verify the content-type that comes
+   back from the server side to make sure that the request is being
+   handled properly.
+
+ * "git help remote-helpers" failed to find the documentation.
+
+ * "gitweb" pages served over HTTPS, when configured to show picon or
+   gravatar, referred to these external resources to be fetched via
+   HTTP, resulting in mixed contents warning in browsers.

+Git 1.8.1.6 Release Notes
+=========================
+
+Fixes since v1.8.1.5
+--------------------
+
+ * An earlier change to the attribute system introduced at v1.8.1.2 by
+   mistake stopped a pattern "dir" (without trailing slash) from

+   to also match).
+
+ * The code to keep track of what directory names are known to Git on
+   platforms with case insensitive filesystems can get confused upon a
+   hash collision between these pathnames and looped forever.
+
+ * When the "--prefix" option is used to "checkout-index", the code
+   did not pick the correct output filter based on the attribute
+   setting.
+
+ * Annotated tags outside refs/tags/ hierarchy were not advertised
+   correctly to the ls-remote and fetch with recent version of Git.
+
+ * The logic used by "git diff -M --stat" to shorten the names of
+   files before and after a rename did not work correctly when the
+   common prefix and suffix between the two filenames overlapped.
+
+ * "git update-index -h" did not do the usual "-h(elp)" thing.
+
+ * perl/Git.pm::cat_blob slurped everything in core only to write it
+   out to a file descriptor, which was not a very smart thing to do.
+
+ * The SSL peer verification done by "git imap-send" did not ask for
+   Server Name Indication (RFC 4366), failing to connect SSL/TLS
+   sites that serve multiple hostnames on a single IP.
+
+ * "git bundle verify" did not say "records a complete history" for a
+   bundle that does not have any prerequisites.

+Git v1.8.1 Release Notes
+========================
+
+Backward compatibility notes
+----------------------------
+
+In the next major release (not *this* one), we will change the
+behavior of the "git push" command.
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  We will use the "simple" semantics that pushes the
+current branch to the branch with the same name, only when the current
+branch is set to integrate with that remote branch.  There is a user
+preference configuration variable "push.default" to change this, and
+"git push" will warn about the upcoming change until you set this
+variable in this release.
+
+"git branch --set-upstream" is deprecated and may be removed in a
+relatively distant future.  "git branch [-u|--set-upstream-to]" has
+been introduced with a saner order of arguments to replace it.
+
+
+Updates since v1.8.0
+--------------------
+
+UI, Workflows & Features
+
+ * Command-line completion scripts for tcsh and zsh have been added.
+
+ * "git-prompt" scriptlet (in contrib/completion) can be told to paint
+   pieces of the hints in the prompt string in colors.
+
+ * Some documentation pages that used to ship only in the plain text
+   format are now formatted in HTML as well.
+
+ * We used to have a workaround for a bug in ancient "less" that
+   causes it to exit without any output when the terminal is resized.
+   The bug has been fixed in "less" version 406 (June 2007), and the
+   workaround has been removed in this release.
+
+ * When "git checkout" checks out a branch, it tells the user how far
+   behind (or ahead) the new branch is relative to the remote tracking
+   branch it builds upon.  The message now also advises how to sync
+   them up by pushing or pulling.  This can be disabled with the
+   advice.statusHints configuration variable.
+
+ * "git config --get" used to diagnose presence of multiple
+   definitions of the same variable in the same configuration file as
+   an error, but it now applies the "last one wins" rule used by the
+   internal configuration logic.  Strictly speaking, this may be an
+   API regression but it is expected that nobody will notice it in
+   practice.
+
+ * A new configuration variable "diff.context" can be used to
+   give the default number of context lines in the patch output, to
+   override the hardcoded default of 3 lines.
+
+ * "git format-patch" learned the "--notes=<ref>" option to give
+   notes for the commit after the three-dash lines in its output.
+
+ * "git log -p -S<string>" now looks for the <string> after applying
+   the textconv filter (if defined); earlier it inspected the contents
+   of the blobs without filtering.
+
+ * "git log --grep=<pcre>" learned to honor the "grep.patterntype"
+   configuration set to "perl".
+
+ * "git replace -d <object>" now interprets <object> as an extended
+   SHA-1 (e.g. HEAD~4 is allowed), instead of only accepting full hex
+   object name.
+
+ * "git rm $submodule" used to punt on removing a submodule working
+   tree to avoid losing the repository embedded in it.  Because
+   recent git uses a mechanism to separate the submodule repository
+   from the submodule working tree, "git rm" learned to detect this
+   case and removes the submodule working tree when it is safe to do so.
+
+ * "git send-email" used to prompt for the sender address, even when
+   the committer identity is well specified (e.g. via user.name and
+   user.email configuration variables).  The command no longer gives
+   this prompt when not necessary.
+
+ * "git send-email" did not allow non-address garbage strings to
+   appear after addresses on Cc: lines in the patch files (and when
+   told to pick them up to find more recipients), e.g.
+
+     Cc: Stable Kernel <stable@k.org> # for v3.2 and up
+
+   The command now strips " # for v3.2 and up" part before adding the
+   remainder of this line to the list of recipients.
+
+ * "git submodule add" learned to add a new submodule at the same
+   path as the path where an unrelated submodule was bound to in an
+   existing revision via the "--name" option.
+
+ * "git submodule sync" learned the "--recursive" option.
+
+ * "diff.submodule" configuration variable can be used to give custom
+   default value to the "git diff --submodule" option.
+
+ * "git symbolic-ref" learned the "-d $symref" option to delete the
+   named symbolic ref, which is more intuitive way to spell it than
+   "update-ref -d --no-deref $symref".
+
+
+Foreign Interface
+
+ * "git cvsimport" can be told to record timezones (other than GMT)
+   per-author via its author info file.
+
+ * The remote helper interface to interact with subversion
+   repositories (one of the GSoC 2012 projects) has been merged.
+
+ * A new remote-helper interface for Mercurial has been added to
+   contrib/remote-helpers.
+
+ * The documentation for git(1) was pointing at a page at an external
+   site for the list of authors that no longer existed.  The link has
+   been updated to point at an alternative site.
+
+
+Performance, Internal Implementation, etc.
+
+ * Compilation on Cygwin with newer header files are supported now.
+
+ * A couple of low-level implementation updates on MinGW.
+
+ * The logic to generate the initial advertisement from "upload-pack"
+   (i.e. what is invoked by "git fetch" on the other side of the
+   connection) to list what refs are available in the repository has
+   been optimized.
+
+ * The logic to find set of attributes that match a given path has
+   been optimized.
+
+ * Use preloadindex in "git diff-index" and "git update-index", which
+   has a nice speedup on systems with slow stat calls (and even on
+   Linux).
+
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.8.0
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.0 in the maintenance
+track are contained in this release (see release notes to them for
+details).
+
+ * The configuration parser had an unnecessary hardcoded limit on
+   variable names that was not checked consistently.
+
+ * The "say" function in the test scaffolding incorrectly allowed
+   "echo" to interpret "\a" as if it were a C-string asking for a
+   BEL output.
+
+ * "git mergetool" feeds /dev/null as a common ancestor when dealing
+   with an add/add conflict, but p4merge backend cannot handle
+   it. Work it around by passing a temporary empty file.
+
+ * "git log -F -E --grep='<ere>'" failed to use the given <ere>
+   pattern as extended regular expression, and instead looked for the
+   string literally.
+
+ * "git grep -e pattern <tree>" asked the attribute system to read
+   "<tree>:.gitattributes" file in the working tree, which was
+   nonsense.
+
+ * A symbolic ref refs/heads/SYM was not correctly removed with "git
+   branch -d SYM"; the command removed the ref pointed by SYM
+   instead.
+
+ * Update "remote tracking branch" in the documentation to
+   "remote-tracking branch".
+
+ * "git pull --rebase" run while the HEAD is detached tried to find
+   the upstream branch of the detached HEAD (which by definition
+   does not exist) and emitted unnecessary error messages.
+
+ * The refs/replace hierarchy was not mentioned in the
+   repository-layout docs.
+
+ * Various rfc2047 quoting issues around a non-ASCII name on the
+   From: line in the output from format-patch have been corrected.
+
+ * Sometimes curl_multi_timeout() function suggested a wrong timeout
+   value when there is no file descriptor to wait on and the http
+   transport ended up sleeping for minutes in select(2) system call.
+   A workaround has been added for this.
+
+ * For a fetch refspec (or the result of applying wildcard on one),
+   we always want the RHS to map to something inside "refs/"
+   hierarchy, but the logic to check it was not exactly right.
+   (merge 5c08c1f jc/maint-fetch-tighten-refname-check later to maint).
+
+ * "git diff -G<pattern>" did not honor textconv filter when looking
+   for changes.
+
+ * Some HTTP servers ask for auth only during the actual packing phase
+   (not in ls-remote phase); this is not really a recommended
+   configuration, but the clients used to fail to authenticate with
+   such servers.
+   (merge 2e736fd jk/maint-http-half-auth-fetch later to maint).
+
+ * "git p4" used to try expanding malformed "$keyword$" that spans
+   across multiple lines.
+
+ * Syntax highlighting in "gitweb" was not quite working.
+
+ * RSS feed from "gitweb" had a xss hole in its title output.
+
+ * "git config --path $key" segfaulted on "[section] key" (a boolean
+   "true" spelled without "=", not "[section] key = true").
+
+ * "git checkout -b foo" while on an unborn branch did not say
+   "Switched to a new branch 'foo'" like other cases.
+
+ * Various codepaths have workaround for a common misconfiguration to
+   spell "UTF-8" as "utf8", but it was not used uniformly.  Most
+   notably, mailinfo (which is used by "git am") lacked this support.
+
+ * We failed to mention a file without any content change but whose
+   permission bit was modified, or (worse yet) a new file without any
+   content in the "git diff --stat" output.
+
+ * When "--stat-count" hides a diffstat for binary contents, the total
+   number of added and removed lines at the bottom was computed
+   incorrectly.
+
+ * When "--stat-count" hides a diffstat for unmerged paths, the total
+   number of affected files at the bottom of the "diff --stat" output
+   was computed incorrectly.
+
+ * "diff --shortstat" miscounted the total number of affected files
+   when there were unmerged paths.
+
+ * "update-ref -d --deref SYM" to delete a ref through a symbolic ref
+   that points to it did not remove it correctly.

+Git v1.8.2.1 Release Notes
+==========================
+
+Fixes since v1.8.2
+------------------
+
+ * An earlier change to the attribute system introduced at v1.8.1.2 by
+   mistake stopped a pattern "dir" (without trailing slash) from
+   matching a directory "dir" (it only wanted to allow pattern "dir/"
+   to also match).
+
+ * Verification of signed tags were not done correctly when not in C
+   or en/US locale.
+
+ * 'git commit -m "$msg"' used to add an extra newline even when
+   $msg already ended with one.
+
+ * The "--match=<pattern>" option of "git describe", when used with
+   "--all" to allow refs that are not annotated tags to be used as a
+   base of description, did not restrict the output from the command
+   to those that match the given pattern.
+
+ * An aliased command spawned from a bare repository that does not say
+   it is bare with "core.bare = yes" is treated as non-bare by mistake.
+
+ * When "format-patch" quoted a non-ascii strings on the header files,
+   it incorrectly applied rfc2047 and chopped a single character in
+   the middle of it.
+
+ * "git archive" reports a failure when asked to create an archive out
+   of an empty tree.  It would be more intuitive to give an empty
+   archive back in such a case.
+
+ * "git tag -f <tag>" always said "Updated tag '<tag>'" even when
+   creating a new tag (i.e. not overwriting nor updating).
+
+ * "git cmd -- ':(top'" was not diagnosed as an invalid syntax, and
+   instead the parser kept reading beyond the end of the string.
+
+ * Annotated tags outside refs/tags/ hierarchy were not advertised
+   correctly to the ls-remote and fetch with recent version of Git.
+
+ * The code to keep track of what directory names are known to Git on
+   platforms with case insensitive filesystems can get confused upon a
+   hash collision between these pathnames and looped forever.
+
+ * The logic used by "git diff -M --stat" to shorten the names of
+   files before and after a rename did not work correctly when the
+   common prefix and suffix between the two filenames overlapped.
+
+ * "git submodule update", when recursed into sub-submodules, did not
+   accumulate the prefix paths.
+
+ * "git am $maildir/" applied messages in an unexpected order; sort
+   filenames read from the maildir/ in a way that is more likely to
+   sort messages in the order the writing MUA meant to, by sorting
+   numeric segment in numeric order and non-numeric segment in
+   alphabetical order.
+
+ * When export-subst is used, "zip" output recorded incorrect
+   size of the file.
+
+ * Some platforms and users spell UTF-8 differently; retry with the
+   most official "UTF-8" when the system does not understand the
+   user-supplied encoding name that are the common alternative
+   spellings of UTF-8.
+
+ * "git branch" did not bother to check nonsense command line
+   parameters and issue errors in many cases.
+
+ * "git update-index -h" did not do the usual "-h(elp)" thing.
+
+ * perl/Git.pm::cat_blob slurped everything in core only to write it
+   out to a file descriptor, which was not a very smart thing to do.
+
+ * The SSL peer verification done by "git imap-send" did not ask for
+   Server Name Indication (RFC 4366), failing to connect SSL/TLS
+   sites that serve multiple hostnames on a single IP.
+
+ * "git index-pack" had a buffer-overflow while preparing an
+   informational message when the translated version of it was too
+   long.
+
+ * Clarify in the documentation "what" gets pushed to "where" when the
+   command line to "git push" does not say these explicitly.
+
+ * In "git reflog expire", REACHABLE bit was not cleared from the
+   correct objects.
+
+ * The "--color=<when>" argument to the commands in the diff family
+   was described poorly.
+
+ * The arguments given to pre-rebase hook were not documented.
+
+ * The v4 index format was not documented.
+
+ * The "--match=<pattern>" argument "git describe" takes uses glob
+   pattern but it wasn't obvious from the documentation.
+
+ * Some sources failed to compile on systems that lack NI_MAXHOST in
+   their system header (e.g. z/OS).
+
+ * Add an example use of "--env-filter" in "filter-branch"
+   documentation.
+
+ * "git bundle verify" did not say "records a complete history" for a
+   bundle that does not have any prerequisites.
+
+ * In the v1.8.0 era, we changed symbols that do not have to be global
+   to file scope static, but a few functions in graph.c were used by
+   CGit from sideways bypassing the entry points of the API the
+   in-tree users use.
+
+ * "git merge-tree" had a typo in the logic to detect d/f conflicts,
+   which caused it to segfault in some cases.

+Git v1.8.2.2 Release Notes
+==========================
+
+Fixes since v1.8.2.1
+--------------------
+
+ * Zsh completion forgot that '%' character used to signal untracked
+   files needs to be escaped with another '%'.
+
+ * A commit object whose author or committer ident are malformed
+   crashed some code that trusted that a name, an email and an
+   timestamp can always be found in it.
+
+ * The new core.commentchar configuration was not applied to a few
+   places.
+
+ * "git pull --rebase" did not pass "-v/-q" options to underlying
+   "git rebase".
+
+ * When receive-pack detects error in the pack header it received in
+   order to decide which of unpack-objects or index-pack to run, it
+   returned without closing the error stream, which led to a hang
+   sideband thread.
+
+ * "git diff --diff-algorithm=algo" was understood by the command line
+   parser, but "git diff --diff-algorithm algo" was not.
+
+ * "git log -S/-G" started paying attention to textconv filter, but
+   there was no way to disable this.  Make it honor --no-textconv
+   option.
+
+ * "git merge $(git rev-parse v1.8.2)" behaved quite differently from
+   "git merge v1.8.2", as if v1.8.2 were written as v1.8.2^0 and did
+   not pay much attention to the annotated tag payload.  Make the code
+   notice the type of the tag object, in addition to the dwim_ref()
+   based classification the current code uses (i.e. the name appears
+   in refs/tags/) to decide when to special case merging of tags.
+
+ * "git cherry-pick" and "git revert" can take more than one commit
+   on the command line these days, but it was not mentioned on the usage
+   text.
+
+ * Perl scripts like "git-svn" closed (not redirecting to /dev/null)
+   the standard error stream, which is not a very smart thing to do.
+   Later open may return file descriptor #2 for unrelated purpose, and
+   error reporting code may write into them.
+
+ * "git apply --whitespace=fix" was not prepared to see a line getting
+   longer after fixing whitespaces (e.g. tab-in-indent aka Python).
+
+ * "git diff/log --cc" did not work well with options that ignore
+   whitespace changes.
+
+ * Documentation on setting up a http server that requires
+   authentication only on the push but not fetch has been clarified.
+
+ * A few bugfixes to "git rerere" working on corner case merge
+   conflicts have been applied.
+
+ * "git bundle" did not like a bundle created using a commit without
+   any message as its one of the prerequisites.

+==========================

+
+ * "rev-list --stdin" and friends kept bogus pointers into the input
+   buffer around as human readable object names.  This was not a
+   huge problem but was exposed by a new change that uses these
+   names in error output.
+
+ * When "git difftool" drove "kdiff3", it mistakenly passed --auto
+   option that was meant while resolving merge conflicts.
+
+ * "git remote add" command did not diagnose extra command line
+   arguments as an error and silently ignored them.
+
+Also contains a handful of trivial code clean-ups, documentation

+Git v1.8.2 Release Notes
+========================
+
+Backward compatibility notes (this release)
+-------------------------------------------
+
+"git push $there tag v1.2.3" used to allow replacing a tag v1.2.3
+that already exists in the repository $there, if the rewritten tag
+you are pushing points at a commit that is a descendant of a commit
+that the old tag v1.2.3 points at.  This was found to be error prone
+and starting with this release, any attempt to update an existing
+ref under refs/tags/ hierarchy will fail, without "--force".
+
+When "git add -u" and "git add -A" that does not specify what paths
+to add on the command line is run from inside a subdirectory, the
+scope of the operation has always been limited to the subdirectory.
+Many users found this counter-intuitive, given that "git commit -a"
+and other commands operate on the entire tree regardless of where you
+are.  In this release, these commands give a warning message that
+suggests the users to use "git add -u/-A ." when they want to limit
+the scope to the current directory; doing so will squelch the message,
+while training their fingers.
+
+
+Backward compatibility notes (for Git 2.0)
+------------------------------------------
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  In Git 2.0, the default will change to the "simple"
+semantics that pushes the current branch to the branch with the same
+name, only when the current branch is set to integrate with that
+remote branch.  There is a user preference configuration variable
+"push.default" to change this.  If you are an old-timer who is used
+to the "matching" semantics, you can set it to "matching" to keep the
+traditional behaviour.  If you want to live in the future early,
+you can set it to "simple" today without waiting for Git 2.0.
+
+When "git add -u" and "git add -A", that does not specify what paths
+to add on the command line is run from inside a subdirectory, these
+commands will operate on the entire tree in Git 2.0 for consistency
+with "git commit -a" and other commands. Because there will be no
+mechanism to make "git add -u" behave as if "git add -u .", it is
+important for those who are used to "git add -u" (without pathspec)
+updating the index only for paths in the current subdirectory to start
+training their fingers to explicitly say "git add -u ." when they mean
+it before Git 2.0 comes.
+
+
+Updates since v1.8.1
+--------------------
+
+UI, Workflows & Features
+
+ * Initial ports to QNX and z/OS UNIX System Services have started.
+
+ * Output from the tests is coloured using "green is okay, yellow is
+   questionable, red is bad and blue is informative" scheme.
+
+ * Mention of "GIT/Git/git" in the documentation have been updated to
+   be more uniform and consistent.  The name of the system and the
+   concept it embodies is "Git"; the command the users type is "git".
+   All-caps "GIT" was merely a way to imitate "Git" typeset in small
+   caps in our ASCII text only documentation and to be avoided.
+
+ * The completion script (in contrib/completion) used to let the
+   default completer to suggest pathnames, which gave too many
+   irrelevant choices (e.g. "git add" would not want to add an
+   unmodified path).  It learnt to use a more git-aware logic to
+   enumerate only relevant ones.
+
+ * In bare repositories, "git shortlog" and other commands now read
+   mailmap files from the tip of the history, to help running these
+   tools in server settings.
+
+ * Color specifiers, e.g. "%C(blue)Hello%C(reset)", used in the
+   "--format=" option of "git log" and friends can be disabled when
+   the output is not sent to a terminal by prefixing them with
+   "auto,", e.g. "%C(auto,blue)Hello%C(auto,reset)".
+
+ * Scripts can ask Git that wildcard patterns in pathspecs they give do
+   not have any significance, i.e. take them as literal strings.
+
+ * The patterns in .gitignore and .gitattributes files can have **/,
+   as a pattern that matches 0 or more levels of subdirectory.
+   E.g. "foo/**/bar" matches "bar" in "foo" itself or in a
+   subdirectory of "foo".
+
+ * When giving arguments without "--" disambiguation, object names
+   that come earlier on the command line must not be interpretable as
+   pathspecs and pathspecs that come later on the command line must
+   not be interpretable as object names.  This disambiguation rule has
+   been tweaked so that ":/" (no other string before or after) is
+   always interpreted as a pathspec; "git cmd -- :/" is no longer
+   needed, you can just say "git cmd :/".
+
+ * Various "hint" lines Git gives when it asks the user to edit
+   messages in the editor are commented out with '#' by default. The
+   core.commentchar configuration variable can be used to customize
+   this '#' to a different character.
+
+ * "git add -u" and "git add -A" without pathspec issues warning to
+   make users aware that they are only operating on paths inside the
+   subdirectory they are in.  Use ":/" (everything from the top) or
+   "." (everything from the $cwd) to disambiguate.
+
+ * "git blame" (and "git diff") learned the "--no-follow" option.
+
+ * "git branch" now rejects some nonsense combinations of command line
+   arguments (e.g. giving more than one branch name to rename) with
+   more case-specific error messages.
+
+ * "git check-ignore" command to help debugging .gitignore files has
+   been added.
+
+ * "git cherry-pick" can be used to replay a root commit to an unborn
+   branch.
+
+ * "git commit" can be told to use --cleanup=whitespace by setting the
+   configuration variable commit.cleanup to 'whitespace'.
+
+ * "git diff" and other Porcelain commands can be told to use a
+   non-standard algorithm by setting diff.algorithm configuration
+   variable.
+
+ * "git fetch --mirror" and fetch that uses other forms of refspec
+   with wildcard used to attempt to update a symbolic ref that match
+   the wildcard on the receiving end, which made little sense (the
+   real ref that is pointed at by the symbolic ref would be updated
+   anyway).  Symbolic refs no longer are affected by such a fetch.
+
+ * "git format-patch" now detects more cases in which a whole branch
+   is being exported, and uses the description for the branch, when
+   asked to write a cover letter for the series.
+
+ * "git format-patch" learned "-v $count" option, and prepends a
+   string "v$count-" to the names of its output files, and also
+   automatically sets the subject prefix to "PATCH v$count". This
+   allows patches from rerolled series to be stored under different
+   names and makes it easier to reuse cover letter messages.
+
+ * "git log" and friends can be told with --use-mailmap option to
+   rewrite the names and email addresses of people using the mailmap
+   mechanism.
+
+ * "git log --cc --graph" now shows the combined diff output with the
+   ancestry graph.
+
+ * "git log --grep=<pattern>" honors i18n.logoutputencoding to look
+   for the pattern after fixing the log message to the specified
+   encoding.
+
+ * "git mergetool" and "git difftool" learned to list the available
+   tool backends in a more consistent manner.
+
+ * "git mergetool" is aware of TortoiseGitMerge now and uses it over
+   TortoiseMerge when available.
+
+ * "git push" now requires "-f" to update a tag, even if it is a
+   fast-forward, as tags are meant to be fixed points.
+
+ * Error messages from "git push" when it stops to prevent remote refs
+   from getting overwritten by mistake have been improved to explain
+   various situations separately.
+
+ * "git push" will stop without doing anything if the new "pre-push"
+   hook exists and exits with a failure.
+
+ * When "git rebase" fails to generate patches to be applied (e.g. due
+   to oom), it failed to detect the failure and instead behaved as if
+   there were nothing to do.  A workaround to use a temporary file has
+   been applied, but we probably would want to revisit this later, as
+   it hurts the common case of not failing at all.
+
+ * Input and preconditions to "git reset" has been loosened where
+   appropriate.  "git reset $fromtree Makefile" requires $fromtree to
+   be any tree (it used to require it to be a commit), for example.
+   "git reset" (without options or parameters) used to error out when
+   you do not have any commits in your history, but it now gives you
+   an empty index (to match non-existent commit you are not even on).
+
+ * "git status" says what branch is being bisected or rebased when
+   able, not just "bisecting" or "rebasing".
+
+ * "git submodule" started learning a new mode to integrate with the
+   tip of the remote branch (as opposed to integrating with the commit
+   recorded in the superproject's gitlink).
+
+ * "git upload-pack" which implements the service "ls-remote" and
+   "fetch" talk to can be told to hide ref hierarchies the server
+   side internally uses (and that clients have no business learning
+   about) with transfer.hiderefs configuration.
+
+
+Foreign Interface
+
+ * "git fast-export" has been updated for its use in the context of
+   the remote helper interface.
+
+ * A new remote helper to interact with bzr has been added to contrib/.
+
+ * "git p4" got various bugfixes around its branch handling.  It is
+   also made usable with Python 2.4/2.5.  In addition, its various
+   portability issues for Cygwin have been addressed.
+
+ * The remote helper to interact with Hg in contrib/ has seen a few
+   fixes.
+
+
+Performance, Internal Implementation, etc.
+
+ * "git fsck" has been taught to be pickier about entries in tree
+   objects that should not be there, e.g. ".", ".git", and "..".
+
+ * Matching paths with common forms of pathspecs that contain wildcard
+   characters has been optimized further.
+
+ * We stopped paying attention to $GIT_CONFIG environment that points
+   at a single configuration file from any command other than "git config"
+   quite a while ago, but "git clone" internally set, exported, and
+   then unexported the variable during its operation unnecessarily.
+
+ * "git reset" internals has been reworked and should be faster in
+   general. We tried to be careful not to break any behaviour but
+   there could be corner cases, especially when running the command
+   from a conflicted state, that we may have missed.
+
+ * The implementation of "imap-send" has been updated to reuse xml
+   quoting code from http-push codepath, and lost a lot of unused
+   code.
+
+ * There is a simple-minded checker for the test scripts in t/
+   directory to catch most common mistakes (it is not enabled by
+   default).
+
+ * You can build with USE_WILDMATCH=YesPlease to use a replacement
+   implementation of pattern matching logic used for pathname-like
+   things, e.g. refnames and paths in the repository.  This new
+   implementation is not expected change the existing behaviour of Git
+   in this release, except for "git for-each-ref" where you can now
+   say "refs/**/master" and match with both refs/heads/master and
+   refs/remotes/origin/master.  We plan to use this new implementation
+   in wider places (e.g. "git ls-files '**/Makefile' may find Makefile
+   at the top-level, and "git log '**/t*.sh'" may find commits that
+   touch a shell script whose name begins with "t" at any level) in
+   future versions of Git, but we are not there yet.  By building with
+   USE_WILDMATCH, using the resulting Git daily and reporting when you
+   find breakages, you can help us get closer to that goal.
+
+ * Some reimplementations of Git do not write all the stat info back
+   to the index due to their implementation limitations (e.g. jgit).
+   A configuration option can tell Git to ignore changes to most of
+   the stat fields and only pay attention to mtime and size, which
+   these implementations can reliably update.  This can be used to
+   avoid excessive revalidation of contents.
+
+ * Some platforms ship with old version of expat where xmlparse.h
+   needs to be included instead of expat.h; the build procedure has
+   been taught about this.
+
+ * "make clean" on platforms that cannot compute header dependencies
+   on the fly did not work with implementations of "rm" that do not
+   like an empty argument list.
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.8.1
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.1 in the maintenance
+track are contained in this release (see release notes to them for
+details).
+
+ * An element on GIT_CEILING_DIRECTORIES list that does not name the
+   real path to a directory (i.e. a symbolic link) could have caused
+   the GIT_DIR discovery logic to escape the ceiling.
+
+ * When attempting to read the XDG-style $HOME/.config/git/config and
+   finding that $HOME/.config/git is a file, we gave a wrong error
+   message, instead of treating the case as "a custom config file does
+   not exist there" and moving on.
+
+ * The behaviour visible to the end users was confusing, when they
+   attempt to kill a process spawned in the editor that was in turn
+   launched by Git with SIGINT (or SIGQUIT), as Git would catch that
+   signal and die.  We ignore these signals now.
+   (merge 0398fc34 pf/editor-ignore-sigint later to maint).
+
+ * A child process that was killed by a signal (e.g. SIGINT) was
+   reported in an inconsistent way depending on how the process was
+   spawned by us, with or without a shell in between.
+
+ * After failing to create a temporary file using mkstemp(), failing
+   pathname was not reported correctly on some platforms.
+
+ * We used to stuff "user@" and then append what we read from
+   /etc/mailname to come up with a default e-mail ident, but a bug
+   lost the "user@" part.
+
+ * The attribute mechanism didn't allow limiting attributes to be
+   applied to only a single directory itself with "path/" like the
+   exclude mechanism does.  The initial implementation of this that
+   was merged to 'maint' and 1.8.1.2 was with a severe performance
+   degradations and needs to merge a fix-up topic.
+
+ * The smart HTTP clients forgot to verify the content-type that comes
+   back from the server side to make sure that the request is being
+   handled properly.
+
+ * "git am" did not parse datestamp correctly from Hg generated patch,
+   when it is run in a locale outside C (or en).
+
+ * "git apply" misbehaved when fixing whitespace breakages by removing
+   excess trailing blank lines.
+
+ * "git apply --summary" has been taught to make sure the similarity
+   value shown in its output is sensible, even when the input had a
+   bogus value.
+
+ * A tar archive created by "git archive" recorded a directory in a
+   way that made NetBSD's implementation of "tar" sometimes unhappy.
+
+ * "git archive" did not record uncompressed size in the header when
+   streaming a zip archive, which confused some implementations of unzip.
+
+ * "git archive" did not parse configuration values in tar.* namespace
+   correctly.
+   (merge b3873c3 jk/config-parsing-cleanup later to maint).
+
+ * Attempt to "branch --edit-description" an existing branch, while
+   being on a detached HEAD, errored out.
+
+ * "git clean" showed what it was going to do, but sometimes end up
+   finding that it was not allowed to do so, which resulted in a
+   confusing output (e.g. after saying that it will remove an
+   untracked directory, it found an embedded git repository there
+   which it is not allowed to remove).  It now performs the actions
+   and then reports the outcome more faithfully.
+
+ * When "git clone --separate-git-dir=$over_there" is interrupted, it
+   failed to remove the real location of the $GIT_DIR it created.
+   This was most visible when interrupting a submodule update.
+
+ * "git cvsimport" mishandled timestamps at DST boundary.
+
+ * We used to have an arbitrary 32 limit for combined diff input,
+   resulting in incorrect number of leading colons shown when showing
+   the "--raw --cc" output.
+
+ * "git fetch --depth" was broken in at least three ways.  The
+   resulting history was deeper than specified by one commit, it was
+   unclear how to wipe the shallowness of the repository with the
+   command, and documentation was misleading.
+   (merge cfb70e1 nd/fetch-depth-is-broken later to maint).
+
+ * "git log --all -p" that walked refs/notes/textconv/ ref can later
+   try to use the textconv data incorrectly after it gets freed.
+
+ * We forgot to close the file descriptor reading from "gpg" output,
+   killing "git log --show-signature" on a long history.
+
+ * The way "git svn" asked for password using SSH_ASKPASS and
+   GIT_ASKPASS was not in line with the rest of the system.
+
+ * The --graph code fell into infinite loop when asked to do what the
+   code did not expect.
+
+ * http transport was wrong to ask for the username when the
+   authentication is done by certificate identity.
+
+ * "git pack-refs" that ran in parallel to another process that
+   created new refs had a nasty race.
+
+ * Rebasing the history of superproject with change in the submodule
+   has been broken since v1.7.12.
+
+ * After "git add -N" and then writing a tree object out of the
+   index, the cache-tree data structure got corrupted.
+
+ * "git clone" used to allow --bare and --separate-git-dir=$there
+   options at the same time, which was nonsensical.
+
+ * "git rebase --preserve-merges" lost empty merges in recent versions
+   of Git.
+
+ * "git merge --no-edit" computed who were involved in the work done
+   on the side branch, even though that information is to be discarded
+   without getting seen in the editor.
+
+ * "git merge" started calling prepare-commit-msg hook like "git
+   commit" does some time ago, but forgot to pay attention to the exit
+   status of the hook.
+
+ * A failure to push due to non-ff while on an unborn branch
+   dereferenced a NULL pointer when showing an error message.
+
+ * When users spell "cc:" in lowercase in the fake "header" in the
+   trailer part, "git send-email" failed to pick up the addresses from
+   there. As e-mail headers field names are case insensitive, this
+   script should follow suit and treat "cc:" and "Cc:" the same way.
+
+ * Output from "git status --ignored" showed an unexpected interaction
+   with "--untracked".
+
+ * "gitweb", when sorting by age to show repositories with new
+   activities first, used to sort repositories with absolutely
+   nothing in it early, which was not very useful.
+
+ * "gitweb"'s code to sanitize control characters before passing it to
+   "highlight" filter lost known-to-be-safe control characters by
+   mistake.
+
+ * "gitweb" pages served over HTTPS, when configured to show picon or
+   gravatar, referred to these external resources to be fetched via
+   HTTP, resulting in mixed contents warning in browsers.
+
+ * When a line to be wrapped has a solid run of non space characters
+   whose length exactly is the wrap width, "git shortlog -w" failed
+   to add a newline after such a line.
+
+ * Command line completion leaked an unnecessary error message while
+   looking for possible matches with paths in <tree-ish>.
+
+ * Command line completion for "tcsh" emitted an unwanted space
+   after completing a single directory name.
+
+ * Command line completion code was inadvertently made incompatible with
+   older versions of bash by using a newer array notation.
+
+ * "git push" was taught to refuse updating the branch that is
+   currently checked out long time ago, but the user manual was left
+   stale.
+   (merge 50995ed wk/man-deny-current-branch-is-default-these-days later to maint).
+
+ * Some shells do not behave correctly when IFS is unset; work it
+   around by explicitly setting it to the default value.
+
+ * Some scripted programs written in Python did not get updated when
+   PYTHON_PATH changed.
+   (cherry-pick 96a4647fca54031974cd6ad1 later to maint).
+
+ * When autoconf is used, any build on a different commit always ran
+   "config.status --recheck" even when unnecessary.
+
+ * A fix was added to the build procedure to work around buggy
+   versions of ccache broke the auto-generation of dependencies, which
+   unfortunately is still relevant because some people use ancient
+   distros.
+
+ * The autoconf subsystem passed --mandir down to generated
+   config.mak.autogen but forgot to do the same for --htmldir.
+   (merge 55d9bf0 ct/autoconf-htmldir later to maint).
+
+ * A change made on v1.8.1.x maintenance track had a nasty regression
+   to break the build when autoconf is used.
+   (merge 7f1b697 jn/less-reconfigure later to maint).
+
+ * We have been carrying a translated and long-unmaintained copy of an
+   old version of the tutorial; removed.
+
+ * t0050 had tests expecting failures from a bug that was fixed some
+   time ago.
+
+ * t4014, t9502 and t0200 tests had various portability issues that
+   broke on OpenBSD.
+
+ * t9020 and t3600 tests had various portability issues.
+
+ * t9200 runs "cvs init" on a directory that already exists, but a
+   platform can configure this fail for the current user (e.g. you
+   need to be in the cvsadmin group on NetBSD 6.0).
+
+ * t9020 and t9810 had a few non-portable shell script construct.
+
+ * Scripts to test bash completion was inherently flaky as it was
+   affected by whatever random things the user may have on $PATH.
+
+ * An element on GIT_CEILING_DIRECTORIES could be a "logical" pathname
+   that uses a symbolic link to point at somewhere else (e.g. /home/me
+   that points at /net/host/export/home/me, and the latter directory
+   is automounted). Earlier when Git saw such a pathname e.g. /home/me
+   on this environment variable, the "ceiling" mechanism did not take
+   effect. With this release (the fix has also been merged to the
+   v1.8.1.x maintenance series), elements on GIT_CEILING_DIRECTORIES
+   are by default checked for such aliasing coming from symbolic
+   links. As this needs to actually resolve symbolic links for each
+   element on the GIT_CEILING_DIRECTORIES, you can disable this
+   mechanism for some elements by listing them after an empty element
+   on the GIT_CEILING_DIRECTORIES. e.g. Setting /home/me::/home/him to
+   GIT_CEILING_DIRECTORIES makes Git resolve symbolic links in
+   /home/me when checking if the current directory is under /home/me,
+   but does not do so for /home/him.
+   (merge 7ec30aa mh/maint-ceil-absolute later to maint).

+

+--------------------
+
+ * Cloning with "git clone --depth N" while fetch.fsckobjects (or
+   transfer.fsckobjects) is set to true did not tell the cut-off
+   points of the shallow history to the process that validates the
+   objects and the history received, causing the validation to fail.
+
+ * "git checkout foo" DWIMs the intended "upstream" and turns it into
+   "git checkout -t -b foo remotes/origin/foo". This codepath has been
+   updated to correctly take existing remote definitions into account.
+
+ * "git fetch" into a shallow repository from a repository that does
+   not know about the shallow boundary commits (e.g. a different fork
+   from the repository the current shallow repository was cloned from)
+   did not work correctly.
+
+ * "git subtree" (in contrib/) had one codepath with loose error
+   checks to lose data at the remote side.
+
+ * "git log --ancestry-path A...B" did not work as expected, as it did
+   not pay attention to the fact that the merge base between A and B
+   was the bottom of the range being specified.
+
+ * "git diff -c -p" was not showing a deleted line from a hunk when
+   another hunk immediately begins where the earlier one ends.
+
+ * "git merge @{-1}~22" was rewritten to "git merge frotz@{1}~22"
+   incorrectly when your previous branch was "frotz" (it should be
+   rewritten to "git merge frotz~22" instead).
+
+ * "git commit --allow-empty-message -m ''" should not start an
+   editor.
+
+ * "git push --[no-]verify" was not documented.
+
+ * An entry for "file://" scheme in the enumeration of URL types Git
+   can take in the HTML documentation was made into a clickable link
+   by mistake.
+
+ * zsh prompt script that borrowed from bash prompt script did not
+   work due to slight differences in array variable notation between
+   these two shells.
+
+ * The bash prompt code (in contrib/) displayed the name of the branch
+   being rebased when "rebase -i/-m/-p" modes are in use, but not the
+   plain vanilla "rebase".
+
+ * "git push $there HEAD:branch" did not resolve HEAD early enough, so
+   it was easy to flip it around while push is still going on and push
+   out a branch that the user did not originally intended when the
+   command was started.
+
+ * "difftool --dir-diff" did not copy back changes made by the
+   end-user in the diff tool backend to the working tree in some
+   cases.

+   other than Git, incorrectly.  This is an old breakage in v1.7.11.

+   path whose name is not in ASCII.
+
+ * "cherry-pick" had a small leak in its error codepath.
+
+ * Logic used by git-send-email to suppress cc mishandled names like
+   "A U. Thor" <author@example.xz>, where the human readable part
+   needs to be quoted (the user input may not have the double quotes
+   around the name, and comparison was done between quoted and
+   unquoted strings).  It also mishandled names that need RFC2047
+   quoting.
+
+ * "gitweb" forgot to clear a global variable $search_regexp upon each
+   request, mistakenly carrying over the previous search to a new one
+   when used as a persistent CGI.
+
+ * The wildmatch engine did not honor WM_CASEFOLD option correctly.

+Git v1.8.3 Release Notes
+========================
+
+Backward compatibility notes (for Git 2.0)
+------------------------------------------
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  In Git 2.0, the default will change to the "simple"
+semantics that pushes only the current branch to the branch with the same
+name, and only when the current branch is set to integrate with that
+remote branch.  Use the user preference configuration variable
+"push.default" to change this.  If you are an old-timer who is used
+to the "matching" semantics, you can set the variable to "matching"
+to keep the traditional behaviour.  If you want to live in the future
+early, you can set it to "simple" today without waiting for Git 2.0.
+
+When "git add -u" (and "git add -A") is run inside a subdirectory and
+does not specify which paths to add on the command line, it
+will operate on the entire tree in Git 2.0 for consistency
+with "git commit -a" and other commands.  There will be no
+mechanism to make plain "git add -u" behave like "git add -u .".
+Current users of "git add -u" (without a pathspec) should start
+training their fingers to explicitly say "git add -u ."
+before Git 2.0 comes.  A warning is issued when these commands are
+run without a pathspec and when you have local changes outside the
+current directory, because the behaviour in Git 2.0 will be different
+from today's version in such a situation.
+
+In Git 2.0, "git add <path>" will behave as "git add -A <path>", so
+that "git add dir/" will notice paths you removed from the directory
+and record the removal.  Versions before Git 2.0, including this
+release, will keep ignoring removals, but the users who rely on this
+behaviour are encouraged to start using "git add --ignore-removal <path>"
+now before 2.0 is released.
+
+
+Updates since v1.8.2
+--------------------
+
+Foreign interface
+
+ * remote-hg and remote-bzr helpers (in contrib/ since v1.8.2) have
+   been updated; especially, the latter has been done in an
+   accelerated schedule (read: we may not have merged to this release
+   if we were following the usual "cook sufficiently in next before
+   unleashing it to the world" workflow) in order to help Emacs folks,
+   whose primary SCM seems to be stagnating.
+
+
+UI, Workflows & Features
+
+ * A handful of updates applied to gitk, including an addition of
+   "revert" action, showing dates in tags in a nicer way, making
+   colors configurable, and support for -G'pickaxe' search.
+
+ * The prompt string generator (in contrib/completion/) learned to
+   show how many changes there are in total and how many have been
+   replayed during a "git rebase" session.
+
+ * "git branch --vv" learned to paint the name of the branch it
+   integrates with in a different color (color.branch.upstream,
+   which defaults to blue).
+
+ * In a sparsely populated working tree, "git checkout <pathspec>" no
+   longer unmarks paths that match the given pathspec that were
+   originally ignored with "--sparse" (use --ignore-skip-worktree-bits
+   option to resurrect these paths out of the index if you really want
+   to).
+
+ * "git log --format" specifier learned %C(auto) token that tells Git
+   to use color when interpolating %d (decoration), %h (short commit
+   object name), etc. for terminal output.
+
+ * "git bisect" leaves the final outcome as a comment in its bisect
+   log file.
+
+ * "git clone --reference" can now refer to a gitfile "textual symlink"
+   that points at the real location of the repository.
+
+ * "git count-objects" learned "--human-readable" aka "-H" option to
+   show various large numbers in Ki/Mi/GiB scaled as necessary.
+
+ * "git cherry-pick $blob" and "git cherry-pick $tree" are nonsense,
+   and a more readable error message e.g. "can't cherry-pick a tree"
+   is given (we used to say "expected exactly one commit").
+
+ * The "--annotate" option to "git send-email" can be turned on (or
+   off) by default with sendemail.annotate configuration variable (you
+   can use --no-annotate from the command line to override it).
+
+ * The "--cover-letter" option to "git format-patch" can be turned on
+   (or off) by default with format.coverLetter configuration
+   variable. By setting it to 'auto', you can turn it on only for a
+   series with two or more patches.
+
+ * The bash completion support (in contrib/) learned that cherry-pick
+   takes a few more options than it already knew about.
+
+ * "git help" learned "-g" option to show the list of guides just like
+   list of commands are given with "-a".
+
+ * A triangular "pull from one place, push to another place" workflow
+   is supported better by new remote.pushdefault (overrides the
+   "origin" thing) and branch.*.pushremote (overrides the
+   branch.*.remote) configuration variables.
+
+ * "git status" learned to report that you are in the middle of a
+   revert session, just like it does for a cherry-pick and a bisect
+   session.
+
+ * The handling by "git branch --set-upstream-to" against various forms
+   of erroneous inputs was suboptimal and has been improved.
+
+ * When the interactive access to git-shell is not enabled, it issues
+   a message meant to help the system administrator to enable it.  An
+   explicit way has been added to issue custom messages to refuse an
+   access over the network to help the end users who connect to the
+   service expecting an interactive shell.
+
+ * In addition to the case where the user edits the log message with
+   the "e)dit" option of "am -i", replace the "Applying: this patch"
+   message with the final log message contents after applymsg hook
+   munges it.
+
+ * "git status" suggests users to look into using --untracked=no option
+   when it takes too long.
+
+ * "git status" shows a bit more information during a rebase/bisect
+   session.
+
+ * "git fetch" learned to fetch a commit at the tip of an unadvertised
+   ref by specifying a raw object name from the command line when the
+   server side supports this feature.
+
+ * Output from "git log --graph" works better with submodule log
+   output now.
+
+ * "git count-objects -v" learned to report leftover temporary
+   packfiles and other garbage in the object store.
+
+ * A new read-only credential helper (in contrib/) to interact with
+   the .netrc/.authinfo files has been added.
+
+ * "git send-email" can be used with the credential helper system.
+
+ * There was no Porcelain way to say "I no longer am interested in
+   this submodule", once you express your interest in a submodule with
+   "submodule init".  "submodule deinit" is the way to do so.
+
+ * "git pull --rebase" learned to pass "-v/-q" options to underlying
+   "git rebase".
+
+ * The new "--follow-tags" option tells "git push" to push relevant
+   annotated tags when pushing branches out.
+
+ * "git merge" and "git pull" can optionally be told to inspect and
+   reject when merging a commit that does not carry a trusted GPG
+   signature.
+
+ * "git mergetool" now feeds files to the "p4merge" backend in the
+   order that matches the p4 convention, where "theirs" is usually
+   shown on the left side, which is the opposite from what other backends
+   expect.
+
+ * "show/log" now honors gpg.program configuration just like other
+   parts of the code that use GnuPG.
+
+ * "git log" that shows the difference between the parent and the
+   child has been optimized somewhat.
+
+ * "git difftool" allows the user to write into the temporary files
+   being shown; if the user makes changes to the working tree at the
+   same time, it now refrains from overwriting the copy in the working
+   tree and leaves the temporary file so that changes can be merged
+   manually.
+
+ * There was no good way to ask "I have a random string that came from
+   outside world. I want to turn it into a 40-hex object name while
+   making sure such an object exists".  A new peeling suffix ^{object}
+   can be used for that purpose, together with "rev-parse --verify".
+
+
+Performance, Internal Implementation, etc.
+
+ * Updates for building under msvc.
+
+ * A handful of issues in the code that traverses the working tree to find
+   untracked and/or ignored files have been fixed, and the general
+   codepath involved in "status -u" and "clean" have been cleaned up
+   and optimized.
+
+ * The stack footprint of some codepaths that access an object from a
+   pack has been shrunk.
+
+ * The logic to coalesce the same lines removed from the parents in
+   the output from "diff -c/--cc" has been updated, but with O(n^2)
+   complexity, so this might turn out to be undesirable.
+
+ * The code to enforce permission bits on files in $GIT_DIR/ for
+   shared repositories has been simplified.
+
+ * A few codepaths know how much data they need to put in the
+   hashtables they use when they start, but still began with small tables
+   and repeatedly grew and rehashed them.
+
+ * The API to walk reflog entries from the latest to older, which was
+   necessary for operations such as "git checkout -", was cumbersome
+   to use correctly and also inefficient.
+
+ * Codepaths that inspect log-message-to-be and decide when to add a
+   new Signed-off-by line in various commands have been consolidated.
+
+ * The pkt-line API, implementation and its callers have been cleaned
+   up to make them more robust.
+
+ * The Cygwin port has a faster-but-lying lstat(2) emulation whose
+   incorrectness does not matter in practice except for a few
+   codepaths, and setting permission bits on directories is a codepath
+   that needs to use a more correct one.
+
+ * "git checkout" had repeated pathspec matches on the same paths,
+   which have been consolidated.  Also a bug in "git checkout dir/"
+   that is started from an unmerged index has been fixed.
+
+ * A few bugfixes to "git rerere" working on corner case merge
+   conflicts have been applied.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v1.8.2
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.2 in the maintenance
+track are contained in this release (see release notes to them for
+details).
+
+ * Recent versions of File::Temp (used by "git svn") started blowing
+   up when its tempfile sub is called as a class method; updated the
+   callsite to call it as a plain vanilla function to fix it.
+   (merge eafc2dd hb/git-pm-tempfile later to maint).
+
+ * Various subcommands of "git remote" simply ignored extraneous
+   command line arguments instead of diagnosing them as errors.
+
+ * When receive-pack detects an error in the pack header it received in
+   order to decide which of unpack-objects or index-pack to run, it
+   returned without closing the error stream, which led to a hung
+   sideband thread.
+
+ * Zsh completion forgot that the '%' character used to signal untracked
+   files needs to be escaped with another '%'.
+
+ * A commit object whose author or committer ident are malformed
+   crashed some code that trusted that a name, an email and a
+   timestamp can always be found in it.
+
+ * When "upload-pack" fails while generating a pack in response to
+   "git fetch" (or "git clone"), the receiving side had
+   a programming error that triggered the die handler
+   recursively.
+
+ * "rev-list --stdin" and friends kept bogus pointers into the input
+   buffer around as human readable object names.  This was not a huge
+   problem but was exposed by a new change that uses these names in
+   error output.
+
+ * Smart-capable HTTP servers were not restricted via the
+   GIT_NAMESPACE mechanism when talking with commit-walking clients,
+   like they are when talking with smart HTTP clients.
+   (merge 6130f86 jk/http-dumb-namespaces later to maint).
+
+ * "git merge-tree" did not omit a merge result that is identical to
+   the "our" side in certain cases.
+   (merge aacecc3 jk/merge-tree-added-identically later to maint).
+
+ * Perl scripts like "git-svn" closed (instead of redirecting to /dev/null)
+   the standard error stream, which is not a very smart thing to do.
+   A later open may return file descriptor #2 for an unrelated purpose, and
+   error reporting code may write into it.
+
+ * "git show-branch" was not prepared to show a very long run of
+   ancestor operators e.g. foobar^2~2^2^2^2...^2~4 correctly.
+
+ * "git diff --diff-algorithm algo" is also understood as "git diff
+   --diff-algorithm=algo".
+
+ * The new core.commentchar configuration was not applied in a few
+   places.
+
+ * "git bundle" erroneously bailed out when parsing a valid bundle
+   containing a prerequisite commit without a commit message.
+
+ * "git log -S/-G" started paying attention to textconv filter, but
+   there was no way to disable this.  Make it honor the --no-textconv
+   option.
+
+ * When used with the "-d temporary-directory" option, "git filter-branch"
+   failed to come back to the original working tree to perform the
+   final clean-up procedure.
+
+ * "git merge $(git rev-parse v1.8.2)" behaved quite differently from
+   "git merge v1.8.2", as if v1.8.2 were written as v1.8.2^0 and did
+   not pay much attention to the annotated tag payload.  Make the code
+   notice the type of the tag object, in addition to the dwim_ref()
+   based classification the current code uses (i.e. the name appears
+   in refs/tags/) to decide when to special-case tag merging.
+
+ * Fix a 1.8.1.x regression that stopped matching "dir" (without a
+   trailing slash) to a directory "dir".
+
+ * "git apply --whitespace=fix" was not prepared to see a line getting
+   longer after fixing whitespaces (e.g. tab-in-indent aka Python).
+
+ * The prompt string generator (in contrib/completion/) did not notice
+   when we are in a middle of a "git revert" session.
+
+ * "submodule summary --summary-limit" option did not support the
+   "--option=value" form.
+
+ * "index-pack --fix-thin" used an uninitialized value to compute
+   the delta depths of objects it appends to the resulting pack.
+
+ * "index-pack --verify-stat" used a few counters outside the protection
+   of a mutex, possibly showing incorrect numbers.
+
+ * The code to keep track of what directory names are known to Git on
+   platforms with case insensitive filesystems could get confused upon a
+   hash collision between these pathnames and would loop forever.
+
+ * Annotated tags outside the refs/tags/ hierarchy were not advertised
+   correctly to ls-remote and fetch with recent versions of Git.
+
+ * Recent optimizations broke shallow clones.
+
+ * "git cmd -- ':(top'" was not diagnosed as an invalid syntax, and
+   instead the parser kept reading beyond the end of the string.
+
+ * "git tag -f <tag>" always said "Updated tag '<tag>'" even when
+   creating a new tag (i.e. neither overwriting nor updating).
+
+ * "git p4" did not behave well when the path to the root of the P4
+   client was not its real path.
+   (merge bbd8486 pw/p4-symlinked-root later to maint).
+
+ * "git archive" reported a failure when asked to create an archive out
+   of an empty tree.  It is more intuitive to give an empty
+   archive back in such a case.
+
+ * When "format-patch" quoted a non-ascii string in header files,
+   it incorrectly applied rfc2047 and chopped a single character in
+   the middle of the string.
+
+ * An aliased command spawned from a bare repository that does not say
+   it is bare with "core.bare = yes" was treated as non-bare by mistake.
+
+ * In "git reflog expire", the REACHABLE bit was not cleared from the
+   correct objects.
+
+ * The logic used by "git diff -M --stat" to shorten the names of
+   files before and after a rename did not work correctly when the
+   common prefix and suffix between the two filenames overlapped.
+
+ * The "--match=<pattern>" option of "git describe", when used with
+   "--all" to allow refs that are not annotated tags to be a
+   base of description, did not restrict the output from the command
+   to those refs that match the given pattern.
+
+ * Clarify in the documentation "what" gets pushed to "where" when the
+   command line to "git push" does not say these explicitly.
+
+ * The "--color=<when>" argument to the commands in the diff family
+   was described poorly.
+
+ * The arguments given to the pre-rebase hook were not documented.
+
+ * The v4 index format was not documented.
+
+ * The "--match=<pattern>" argument "git describe" takes uses glob
+   pattern but it wasn't obvious from the documentation.
+
+ * Some sources failed to compile on systems that lack NI_MAXHOST in
+   their system header (e.g. z/OS).
+
+ * Add an example use of "--env-filter" in "filter-branch"
+   documentation.
+
+ * "git bundle verify" did not say "records a complete history" for a
+   bundle that does not have any prerequisites.
+
+ * In the v1.8.0 era, we changed symbols that do not have to be global
+   to file scope static, but a few functions in graph.c were used by
+   CGit sideways, bypassing the entry points of the API the
+   in-tree users use.
+
+ * "git update-index -h" did not do the usual "-h(elp)" thing.
+
+ * "git index-pack" had a buffer-overflow while preparing an
+   informational message when the translated version of it was too
+   long.
+
+ * 'git commit -m "$msg"' used to add an extra newline even when
+   $msg already ended with one.
+
+ * The SSL peer verification done by "git imap-send" did not ask for
+   Server Name Indication (RFC 4366), failing to connect to SSL/TLS
+   sites that serve multiple hostnames on a single IP.
+
+ * perl/Git.pm::cat_blob slurped everything in core only to write it
+   out to a file descriptor, which was not a very smart thing to do.
+
+ * "git branch" did not bother to check nonsense command line
+   parameters.  It now issues errors in many cases.
+
+ * Verification of signed tags was not done correctly when not in C
+   or en/US locale.
+
+ * Some platforms and users spell UTF-8 differently; retry with the
+   most official "UTF-8" when the system does not understand the
+   user-supplied encoding name that is a common alternative
+   spelling of UTF-8.
+
+ * When export-subst is used, "zip" output recorded an incorrect
+   size of the file.
+
+ * "git am $maildir/" applied messages in an unexpected order; sort
+   filenames read from the maildir/ in a way that is more likely to
+   sort the messages in the order the writing MUA meant to, by sorting
+   numeric segments in numeric order and non-numeric segments in
+   alphabetical order.
+
+ * "git submodule update", when recursed into sub-submodules, did not
+   accumulate the prefix paths.

+Git v1.8.4.1 Release Notes
+========================
+
+Fixes since v1.8.4
+------------------
+
+ * Some old versions of bash do not grok some constructs like
+   'printf -v varname' which the prompt and completion code started
+   to use recently.  The completion and prompt scripts have been
+   adjusted to work better with these old versions of bash.
+
+ * In FreeBSD's and NetBSD's "sh", a return in a dot script in a
+   function returns from the function, not only in the dot script,
+   breaking "git rebase" on these platforms (regression introduced
+   in 1.8.4-rc1).
+
+ * "git rebase -i" and other scripted commands were feeding a
+   random, data dependant error message to 'echo' and expecting it
+   to come out literally.
+
+ * Setting the "submodule.<name>.path" variable to the empty
+   "true" caused the configuration parser to segfault.
+
+ * Output from "git log --full-diff -- <pathspec>" looked strange
+   because comparison was done with the previous ancestor that
+   touched the specified <pathspec>, causing the patches for paths
+   outside the pathspec to show more than the single commit has
+   changed.
+
+ * The auto-tag-following code in "git fetch" tries to reuse the
+   same transport twice when the serving end does not cooperate and
+   does not give tags that point to commits that are asked for as
+   part of the primary transfer.  Unfortunately, Git-aware transport
+   helper interface is not designed to be used more than once, hence
+   this did not work over smart-http transfer.  Fixed.
+
+ * Send a large request to read(2)/write(2) as a smaller but still
+   reasonably large chunks, which would improve the latency when the
+   operation needs to be killed and incidentally works around broken
+   64-bit systems that cannot take a 2GB write or read in one go.
+
+ * A ".mailmap" file that ends with an incomplete line, when read
+   from a blob, was not handled properly.
+
+ * The recent "short-cut clone connectivity check" topic broke a
+   shallow repository when a fetch operation tries to auto-follow
+   tags.
+
+ * When send-email comes up with an error message to die with upon
+   failure to start an SSL session, it tried to read the error
+   string from a wrong place.
+
+ * A call to xread() was used without a loop to cope with short
+   read in the codepath to stream large blobs to a pack.
+
+ * On platforms with fgetc() and friends defined as macros, the
+   configuration parser did not compile.
+
+ * New versions of MediaWiki introduced a new API for returning
+   more than 500 results in response to a query, which would cause
+   the MediaWiki remote helper to go into an infinite loop.
+
+ * Subversion's serf access method (the only one available in
+   Subversion 1.8) for http and https URLs in skelta mode tells its
+   caller to open multiple files at a time, which made "git svn
+   fetch" complain that "Temp file with moniker 'svn_delta' already
+   in use" instead of fetching.
+
+
+Also contains a handful of trivial code clean-ups, documentation
+updates, updates to the test suite, etc.

+Git v1.8.4.2 Release Notes
+========================
+
+Fixes since v1.8.4.1
+--------------------
+
+ * "git clone" gave some progress messages to the standard output, not
+   to the standard error, and did not allow suppressing them with the
+   "--no-progress" option.
+
+ * "format-patch --from=<whom>" forgot to omit unnecessary in-body
+   from line, i.e. when <whom> is the same as the real author.
+
+ * "git shortlog" used to choke and die when there is a malformed
+   commit (e.g. missing authors); it now simply ignore such a commit
+   and keeps going.
+
+ * "git merge-recursive" did not parse its "--diff-algorithm=" command
+   line option correctly.
+
+ * "git branch --track" had a minor regression in v1.8.3.2 and later
+   that made it impossible to base your local work on anything but a
+   local branch of the upstream repository you are tracking from.
+
+ * "git ls-files -k" needs to crawl only the part of the working tree
+   that may overlap the paths in the index to find killed files, but
+   shared code with the logic to find all the untracked files, which
+   made it unnecessarily inefficient.
+
+ * When there is no sufficient overlap between old and new history
+   during a "git fetch" into a shallow repository, objects that the
+   sending side knows the receiving end has were unnecessarily sent.
+
+ * When running "fetch -q", a long silence while the sender side
+   computes the set of objects to send can be mistaken by proxies as
+   dropped connection.  The server side has been taught to send a
+   small empty messages to keep the connection alive.
+
+ * When the webserver responds with "405 Method Not Allowed", "git
+   http-backend" should tell the client what methods are allowed with
+   the "Allow" header.
+
+ * "git cvsserver" computed the permission mode bits incorrectly for
+   executable files.
+
+ * The implementation of "add -i" has a crippling code to work around
+   ActiveState Perl limitation but it by mistake also triggered on Git
+   for Windows where MSYS perl is used.
+
+ * We made sure that we notice the user-supplied GIT_DIR is actually a
+   gitfile, but did not do the same when the default ".git" is a
+   gitfile.
+
+ * When an object is not found after checking the packfiles and then
+   loose object directory, read_sha1_file() re-checks the packfiles to
+   prevent racing with a concurrent repacker; teach the same logic to
+   has_sha1_file().
+
+ * "git commit --author=$name", when $name is not in the canonical
+   "A. U. Thor <au.thor@example.xz>" format, looks for a matching name
+   from existing history, but did not consult mailmap to grab the
+   preferred author name.
+
+ * The commit object names in the insn sheet that was prepared at the
+   beginning of "rebase -i" session can become ambiguous as the
+   rebasing progresses and the repository gains more commits. Make
+   sure the internal record is kept with full 40-hex object names.
+
+ * "git rebase --preserve-merges" internally used the merge machinery
+   and as a side effect, left merge summary message in the log, but
+   when rebasing, there should not be a need for merge summary.
+
+ * "git rebase -i" forgot that the comment character can be
+   configurable while reading its insn sheet.
+
+Also contains a handful of trivial code clean-ups, documentation
+updates, updates to the test suite, etc.

+Git v1.8.4.3 Release Notes
+========================
+
+Fixes since v1.8.4.2
+--------------------
+
+ * The interaction between use of Perl in our test suite and NO_PERL
+   has been clarified a bit.
+
+ * A fast-import stream expresses a pathname with funny characters by
+   quoting them in C style; remote-hg remote helper (in contrib/)
+   forgot to unquote such a path.
+
+ * One long-standing flaw in the pack transfer protocol used by "git
+   clone" was that there was no way to tell the other end which branch
+   "HEAD" points at, and the receiving end needed to guess.  A new
+   capability has been defined in the pack protocol to convey this
+   information so that cloning from a repository with more than one
+   branches pointing at the same commit where the HEAD is at now
+   reliably sets the initial branch in the resulting repository.
+
+ * We did not handle cases where http transport gets redirected during
+   the authorization request (e.g. from http:// to https://).
+
+ * "git rev-list --objects ^v1.0^ v1.0" gave v1.0 tag itself in the
+   output, but "git rev-list --objects v1.0^..v1.0" did not.
+
+ * The fall-back parsing of commit objects with broken author or
+   committer lines were less robust than ideal in picking up the
+   timestamps.
+
+ * Bash prompting code to deal with an SVN remote as an upstream
+   were coded in a way not supported by older Bash versions (3.x).
+
+ * "git checkout topic", when there is not yet a local "topic" branch
+   but there is a unique remote-tracking branch for a remote "topic"
+   branch, pretended as if "git checkout -t -b topic remote/$r/topic"
+   (for that unique remote $r) was run. This hack however was not
+   implemented for "git checkout topic --".
+
+ * Coloring around octopus merges in "log --graph" output was screwy.
+
+ * We did not generate HTML version of documentation to "git subtree"
+   in contrib/.
+
+ * The synopsis section of "git unpack-objects" documentation has been
+   clarified a bit.
+
+ * An ancient How-To on serving Git repositories on an HTTP server
+   lacked a warning that it has been mostly superseded with more
+   modern way.
+
+Also contains a handful of trivial code clean-ups, documentation
+updates, updates to the test suite, etc.

+Git v1.8.4 Release Notes
+========================
+
+Backward compatibility notes (for Git 2.0)
+------------------------------------------
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  In Git 2.0, the default will change to the "simple"
+semantics that pushes:
+
+ - only the current branch to the branch with the same name, and only
+   when the current branch is set to integrate with that remote
+   branch, if you are pushing to the same remote as you fetch from; or
+
+ - only the current branch to the branch with the same name, if you
+   are pushing to a remote that is not where you usually fetch from.
+
+Use the user preference configuration variable "push.default" to
+change this.  If you are an old-timer who is used to the "matching"
+semantics, you can set the variable to "matching" to keep the
+traditional behaviour.  If you want to live in the future early, you
+can set it to "simple" today without waiting for Git 2.0.
+
+When "git add -u" (and "git add -A") is run inside a subdirectory and
+does not specify which paths to add on the command line, it
+will operate on the entire tree in Git 2.0 for consistency
+with "git commit -a" and other commands.  There will be no
+mechanism to make plain "git add -u" behave like "git add -u .".
+Current users of "git add -u" (without a pathspec) should start
+training their fingers to explicitly say "git add -u ."
+before Git 2.0 comes.  A warning is issued when these commands are
+run without a pathspec and when you have local changes outside the
+current directory, because the behaviour in Git 2.0 will be different
+from today's version in such a situation.
+
+In Git 2.0, "git add <path>" will behave as "git add -A <path>", so
+that "git add dir/" will notice paths you removed from the directory
+and record the removal.  Versions before Git 2.0, including this
+release, will keep ignoring removals, but the users who rely on this
+behaviour are encouraged to start using "git add --ignore-removal <path>"
+now before 2.0 is released.
+
+
+Updates since v1.8.3
+--------------------
+
+Foreign interfaces, subsystems and ports.
+
+ * Cygwin port has been updated for more recent Cygwin 1.7.
+
+ * "git rebase -i" now honors --strategy and -X options.
+
+ * Git-gui has been updated to its 0.18.0 version.
+
+ * MediaWiki remote helper (in contrib/) has been updated to use the
+   credential helper interface from Git.pm.
+
+ * Update build for Cygwin 1.[57].  Torsten Bögershausen reports that
+   this is fine with Cygwin 1.7 ($gmane/225824) so let's try moving it
+   ahead.
+
+ * The credential helper to talk to keychain on OS X (in contrib/) has
+   been updated to kick in not just when talking http/https but also
+   imap(s) and smtp.
+
+ * Remote transport helper has been updated to report errors and
+   maintain ref hierarchy used to keep track of its own state better.
+
+ * With "export" remote-helper protocol, (1) a push that tries to
+   update a remote ref whose name is different from the pushing side
+   does not work yet, and (2) the helper may not know how to do
+   --dry-run; these problematic cases are disabled for now.
+
+ * git-remote-hg/bzr (in contrib/) updates.
+
+ * git-remote-mw (in contrib/) hints users to check the certificate,
+   when https:// connection failed.
+
+ * git-remote-mw (in contrib/) adds a command to allow previewing the
+   contents locally before pushing it out, when working with a
+   MediaWiki remote.
+
+
+UI, Workflows & Features
+
+ * Sample "post-receive-email" hook script got an enhanced replacement
+   "multimail" (in contrib/).
+
+ * Also in contrib/ is a new "contacts" script that runs "git blame"
+   to find out the people who may be interested in a set of changes.
+
+ * "git clean" command learned an interactive mode.
+
+ * The "--head" option to "git show-ref" was only to add "HEAD" to the
+   list of candidate refs to be filtered by the usual rules
+   (e.g. "--heads" that only show refs under refs/heads).  The meaning
+   of the option has been changed to always show "HEAD" regardless of
+   what filtering will be applied to any other ref.
+
+   This is a backward incompatible change and might cause breakages to
+   people's existing scripts.
+
+ * "git show -s" was less discoverable than it should have been.  It
+   now has a natural synonym "git show --no-patch".
+
+ * "git check-mailmap" is a new command that lets you map usernames
+   and e-mail addresses through the mailmap mechanism, just like many
+   built-in commands do.
+
+ * "git name-rev" learned to name an annotated tag object back to its
+   tagname; "git name-rev $(git rev-parse v1.0.0)" gives "tags/v1.0.0",
+   for example.
+
+ * "git cat-file --batch-check=<format>" is added, primarily to allow
+   on-disk footprint of objects in packfiles (often they are a lot
+   smaller than their true size, when expressed as deltas) to be
+   reported.
+
+ * "git rebase [-i]" used to leave just "rebase" as its reflog messages
+   for some operations. They have been reworded to be more informative.
+
+ * In addition to the choice from "rebase, merge, or checkout-detach",
+   "submodule update" can allow a custom command to be used in to
+   update the working tree of submodules via the "submodule.*.update"
+   configuration variable.
+
+ * "git submodule update" can optionally clone the submodule
+   repositories shallowly.
+
+ * "git format-patch" learned "--from[=whom]" option, which sets the
+   "From: " header to the specified person (or the person who runs the
+   command, if "=whom" part is missing) and move the original author
+   information to an in-body From: header as necessary.
+
+ * The configuration variable "merge.ff" was cleary a tri-state to
+   choose one from "favor fast-forward when possible", "always create
+   a merge even when the history could fast-forward" and "do not
+   create any merge, only update when the history fast-forwards", but
+   the command line parser did not implement the usual convention of
+   "last one wins, and command line overrides the configuration"
+   correctly.
+
+ * "gitweb" learned to optionally place extra links that point at the
+   levels higher than the Gitweb pages themselves in the breadcrumbs,
+   so that it can be used as part of a larger installation.
+
+ * "git log --format=" now honors i18n.logoutputencoding configuration
+   variable.
+
+ * The "push.default=simple" mode of "git push" has been updated to
+   behave like "current" without requiring a remote tracking
+   information, when you push to a remote that is different from where
+   you fetch from (i.e. a triangular workflow).
+
+ * Having multiple "fixup!" on a line in the rebase instruction sheet
+   did not work very well with "git rebase -i --autosquash".
+
+ * "git log" learned the "--author-date-order" option, with which the
+   output is topologically sorted and commits in parallel histories
+   are shown intermixed together based on the author timestamp.
+
+ * Various subcommands of "git submodule" refused to run from anywhere
+   other than the top of the working tree of the superproject, but
+   they have been taught to let you run from a subdirectory.
+
+ * "git diff" learned a mode that ignores hunks whose change consists
+   only of additions and removals of blank lines, which is the same as
+   "diff -B" (ignore blank lines) of GNU diff.
+
+ * "git rm" gives a single message followed by list of paths to report
+   multiple paths that cannot be removed.
+
+ * "git rebase" can be told with ":/look for this string" syntax commits
+   to replay the changes onto and where the work to be replayed begins.
+
+ * Many tutorials teach users to set "color.ui" to "auto" as the first
+   thing after you set "user.name/email" to introduce yourselves to
+   Git.  Now the variable defaults to "auto".
+
+ * On Cygwin, "cygstart" is now recognised as a possible way to start
+   a web browser (used in "help -w" and "instaweb" among others).
+
+ * "git status" learned status.branch and status.short configuration
+   variables to use --branch and --short options by default (override
+   with --no-branch and --no-short options from the command line).
+
+ * "git cmd <name>", when <name> happens to be a 40-hex string,
+   directly uses the 40-hex string as an object name, even if a ref
+   "refs/<some hierarchy>/<name>" exists.  This disambiguation order
+   is unlikely to change, but we should warn about the ambiguity just
+   like we warn when more than one refs/ hierarchies share the same
+   name.
+
+ * "git rebase" learned "--[no-]autostash" option to save local
+   changes instead of refusing to run (to which people's normal
+   response was to stash them and re-run).  This introduced a corner
+   case breakage to "git am --abort" but it has been fixed.
+
+ * "check-ignore" (new feature since 1.8.2) has been updated to work
+   more like "check-attr" over bidi-pipes.
+
+ * "git describe" learned "--first-parent" option to limit its closest
+   tagged commit search to the first-parent chain.
+
+ * "git merge foo" that might have meant "git merge origin/foo" is
+   diagnosed with a more informative error message.
+
+ * "git log -L<line>,<range>:<filename>" has been added.  This may
+   still have leaks and rough edges, though.
+
+ * We used the approxidate() parser for "--expire=<timestamp>" options
+   of various commands, but it is better to treat --expire=all and
+   --expire=now a bit more specially than using the current timestamp.
+   "git gc" and "git reflog" have been updated with a new parsing
+   function for expiry dates.
+
+ * Updates to completion (both bash and zsh) helpers.
+
+ * The behaviour of the "--chain-reply-to" option of "git send-email"
+   have changed at 1.7.0, and we added a warning/advice message to
+   help users adjust to the new behaviour back then, but we kept it
+   around for too long.  The message has finally been removed.
+
+ * "git fetch origin master" unlike "git fetch origin" or "git fetch"
+   did not update "refs/remotes/origin/master"; this was an early
+   design decision to keep the update of remote tracking branches
+   predictable, but in practice it turns out that people find it more
+   convenient to opportunistically update them whenever we have a
+   chance, and we have been updating them when we run "git push" which
+   already breaks the original "predictability" anyway.
+
+ * The configuration variable core.checkstat was advertised in the
+   documentation but the code expected core.statinfo instead.
+   For now, we accept both core.checkstat and core.statinfo, but the
+   latter will be removed in the longer term.
+
+
+Performance, Internal Implementation, etc.
+
+ * On Cygwin, we used to use our own lstat(2) emulation that is
+   allegedly faster than the platform one in codepaths where some of
+   the information it returns did not matter, but it started to bite
+   us in a few codepaths where the trick it uses to cheat does show
+   breakages. This emulation has been removed and we use the native
+   lstat(2) emulation supplied by Cygwin now.
+
+ * The function attributes extensions are used to catch mistakes in
+   use of our own variadic functions that use NULL sentinel at the end
+   (i.e. like execl(3)) and format strings (i.e. like printf(3)).
+
+ * The code to allow configuration data to be read from in-tree blob
+   objects is in.  This may help working in a bare repository and
+   submodule updates.
+
+ * Fetching between repositories with many refs employed O(n^2)
+   algorithm to match up the common objects, which has been corrected.
+
+ * The original way to specify remote repository using .git/branches/
+   used to have a nifty feature.  The code to support the feature was
+   still in a function but the caller was changed not to call it 5
+   years ago, breaking that feature and leaving the supporting code
+   unreachable.  The dead code has been removed.
+
+ * "git pack-refs" that races with new ref creation or deletion have
+   been susceptible to lossage of refs under right conditions, which
+   has been tightened up.
+
+ * We read loose and packed references in two steps, but after
+   deciding to read a loose ref but before actually opening it to read
+   it, another process racing with us can unlink it, which would cause
+   us to barf.  The codepath has been updated to retry when such a
+   race is detected, instead of outright failing.
+
+ * Uses of the platform fnmatch(3) function (many places in the code,
+   matching pathspec, .gitignore and .gitattributes to name a few)
+   have been replaced with wildmatch, allowing "foo/**/bar" that would
+   match foo/bar, foo/a/bar, foo/a/b/bar, etc.
+
+ * Memory ownership and lifetime rules for what for-each-ref feeds to
+   its callbacks have been clarified (in short, "you do not own it, so
+   make a copy if you want to keep it").
+
+ * The revision traversal logic to improve culling of irrelevant
+   parents while traversing a mergy history has been updated.
+
+ * Some leaks in unpack-trees (used in merge, cherry-pick and other
+   codepaths) have been plugged.
+
+ * The codepath to read from marks files in fast-import/export did not
+   have to accept anything but 40-hex representation of the object
+   name.  Further, fast-export did not need full in-core object
+   representation to have parsed wen reading from them.  These
+   codepaths have been optimized by taking advantage of these access
+   patterns.
+
+ * Object lookup logic, when the object hashtable starts to become
+   crowded, has been optimized.
+
+ * When TEST_OUTPUT_DIRECTORY setting is used, it was handled somewhat
+   inconsistently between the test framework and t/Makefile, and logic
+   to summarize the results looked at a wrong place.
+
+ * "git clone" uses a lighter-weight implementation when making sure
+   that the history behind refs are complete.
+
+ * Many warnings from sparse source checker in compat/ area has been
+   squelched.
+
+ * The code to reading and updating packed-refs file has been updated,
+   correcting corner case bugs.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v1.8.3
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.3 in the maintenance
+track are contained in this release (see release notes to them for
+details).
+
+ * Newer Net::SMTP::SSL module does not want the user programs to use
+   the default behaviour to let server certificate go without
+   verification, so by default enable the verification with a
+   mechanism to turn it off if needed.
+   (merge 35035bb rr/send-email-ssl-verify later to maint).
+
+ * When "git" is spawned in such a way that any of the low 3 file
+   descriptors is closed, our first open() may yield file descriptor 2,
+   and writing error message to it would screw things up in a big way.
+   (merge a11c396 tr/protect-low-3-fds later to maint).
+
+ * The mailmap mechanism unnecessarily downcased the e-mail addresses
+   in the output, and also ignored the human name when it is a single
+   character name.
+   (merge bd23794 jc/mailmap-case-insensitivity later to maint).
+
+ * In two places we did not check return value (expected to be a file
+   descriptor) correctly.
+   (merge a77f106 tr/fd-gotcha-fixes later to maint).
+
+ * Logic to auto-detect character encodings in the commit log message
+   did not reject overlong and invalid UTF-8 characters.
+   (merge 81050ac bc/commit-invalid-utf8 later to maint).
+
+ * Pass port number as a separate argument when "send-email" initializes
+   Net::SMTP, instead of as a part of the hostname, i.e. host:port.
+   This allows GSSAPI codepath to match with the hostname given.
+   (merge 1a741bf bc/send-email-use-port-as-separate-param later to maint).
+
+ * "git diff" refused to even show difference when core.safecrlf is
+   set to true (i.e. error out) and there are offending lines in the
+   working tree files.
+   (merge 5430bb2 jc/maint-diff-core-safecrlf later to maint).
+
+ * A test that should have failed but didn't revealed a bug that needs
+   to be corrected.
+   (merge 94d75d1 jc/t1512-fix later to maint).
+
+ * An overlong path to a .git directory may have overflown the
+   temporary path buffer used to create a name for lockfiles.
+   (merge 2fbd4f9 mh/maint-lockfile-overflow later to maint).
+
+ * Invocations of "git checkout" used internally by "git rebase" were
+   counted as "checkout", and affected later "git checkout -" to the
+   the user to an unexpected place.
+   (merge 3bed291 rr/rebase-checkout-reflog later to maint).
+
+ * The configuration variable column.ui was poorly documented.
+   (merge 5e62cc1 rr/column-doc later to maint).
+
+ * "git name-rev --refs=tags/v*" were forbidden, which was a bit
+   inconvenient (you had to give a pattern to match refs fully, like
+   --refs=refs/tags/v*).
+   (merge 98c5c4a nk/name-rev-abbreviated-refs later to maint).
+
+ * "git apply" parsed patches that add new files, generated by
+   programs other than Git, incorrectly.  This is an old breakage in
+   v1.7.11 and will need to be merged down to the maintenance tracks.
+
+ * Older cURL wanted piece of memory we call it with to be stable, but
+   we updated the auth material after handing it to a call.
+
+ * "git pull" into nothing trashed "local changes" that were in the
+   index, and this avoids it.
+
+ * Many "git submodule" operations do not work on a submodule at a
+   path whose name is not in ASCII.
+
+ * "cherry-pick" had a small leak in an error codepath.
+
+ * Logic used by git-send-email to suppress cc mishandled names like
+   "A U. Thor" <author@example.xz>, where the human readable part
+   needs to be quoted (the user input may not have the double quotes
+   around the name, and comparison was done between quoted and
+   unquoted strings).  It also mishandled names that need RFC2047
+   quoting.
+
+ * Call to discard_cache/discard_index (used when we use different
+   contents of the index in-core, in many operations like commit,
+   apply, and merge) used to leak memory that held the array of index
+   entries, which has been plugged.
+   (merge a0fc4db rs/discard-index-discard-array later to maint).
+
+ * "gitweb" forgot to clear a global variable $search_regexp upon each
+   request, mistakenly carrying over the previous search to a new one
+   when used as a persistent CGI.
+
+ * The wildmatch engine did not honor WM_CASEFOLD option correctly.
+
+ * "git log -c --follow $path" segfaulted upon hitting the commit that
+   renamed the $path being followed.
+
+ * When a reflog notation is used for implicit "current branch", we
+   did not say which branch and worse said "branch ''".
+
+ * "difftool --dir-diff" did not copy back changes made by the
+   end-user in the diff tool backend to the working tree in some
+   cases.
+
+ * "git push $there HEAD:branch" did not resolve HEAD early enough, so
+   it was easy to flip it around while push is still going on and push
+   out a branch that the user did not originally intended when the
+   command was started.
+
+ * The bash prompt code (in contrib/) displayed the name of the branch
+   being rebased when "rebase -i/-m/-p" modes are in use, but not the
+   plain vanilla "rebase".
+
+ * Handling of negative exclude pattern for directories "!dir" was
+   broken in the update to v1.8.3.
+
+ * zsh prompt script that borrowed from bash prompt script did not
+   work due to slight differences in array variable notation between
+   these two shells.
+
+ * An entry for "file://" scheme in the enumeration of URL types Git
+   can take in the HTML documentation was made into a clickable link
+   by mistake.
+
+ * "git push --[no-]verify" was not documented.
+
+ * Stop installing the git-remote-testpy script that is only used for
+   testing.
+
+ * "git commit --allow-empty-message -m ''" should not start an
+   editor.
+
+ * "git merge @{-1}~22" was rewritten to "git merge frotz@{1}~22"
+   incorrectly when your previous branch was "frotz" (it should be
+   rewritten to "git merge frotz~22" instead).
+
+ * "git diff -c -p" was not showing a deleted line from a hunk when
+   another hunk immediately begins where the earlier one ends.
+
+ * "git log --ancestry-path A...B" did not work as expected, as it did
+   not pay attention to the fact that the merge base between A and B
+   was the bottom of the range being specified.
+
+ * Mac OS X does not like to write(2) more than INT_MAX number of
+   bytes; work it around by chopping write(2) into smaller pieces.
+
+ * Newer MacOS X encourages the programs to compile and link with
+   their CommonCrypto, not with OpenSSL.
+
+ * "git clone foo/bar:baz" cannot be a request to clone from a remote
+   over git-over-ssh specified in the scp style.  This case is now
+   detected and clones from a local repository at "foo/bar:baz".
+
+ * When $HOME is misconfigured to point at an unreadable directory, we
+   used to complain and die. Loosen the check.
+
+ * "git subtree" (in contrib/) had one codepath with loose error
+   checks to lose data at the remote side.
+
+ * "git fetch" into a shallow repository from a repository that does
+   not know about the shallow boundary commits (e.g. a different fork
+   from the repository the current shallow repository was cloned from)
+   did not work correctly.
+
+ * "git checkout foo" DWIMs the intended "upstream" and turns it into
+   "git checkout -t -b foo remotes/origin/foo". This codepath has been
+   updated to correctly take existing remote definitions into account.

+ * We used to allow committing a path ".Git/config" with Git that is

+   filesystem but in order to protect those on HFS+ and on case
+   insensitive filesystems, this check is enabled on all platforms.
+
+A big "thanks!" for bringing this issue to us goes to our friends in

+========================
+
+Backward compatibility notes (for Git 2.0)
+------------------------------------------
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  In Git 2.0, the default will change to the "simple"
+semantics, which pushes:

+ - only the current branch to the branch with the same name, and only
+   when the current branch is set to integrate with that remote
+   branch, if you are pushing to the same remote as you fetch from; or
+
+ - only the current branch to the branch with the same name, if you
+   are pushing to a remote that is not where you usually fetch from.
+
+Use the user preference configuration variable "push.default" to
+change this.  If you are an old-timer who is used to the "matching"
+semantics, you can set the variable to "matching" to keep the
+traditional behaviour.  If you want to live in the future early, you
+can set it to "simple" today without waiting for Git 2.0.
+
+When "git add -u" (and "git add -A") is run inside a subdirectory and
+does not specify which paths to add on the command line, it
+will operate on the entire tree in Git 2.0 for consistency
+with "git commit -a" and other commands.  There will be no
+mechanism to make plain "git add -u" behave like "git add -u .".
+Current users of "git add -u" (without a pathspec) should start
+training their fingers to explicitly say "git add -u ."
+before Git 2.0 comes.  A warning is issued when these commands are
+run without a pathspec and when you have local changes outside the
+current directory, because the behaviour in Git 2.0 will be different
+from today's version in such a situation.
+
+In Git 2.0, "git add <path>" will behave as "git add -A <path>", so
+that "git add dir/" will notice paths you removed from the directory
+and record the removal.  Versions before Git 2.0, including this
+release, will keep ignoring removals, but the users who rely on this
+behaviour are encouraged to start using "git add --ignore-removal <path>"
+now before 2.0 is released.
+
+The default prefix for "git svn" will change in Git 2.0.  For a long
+time, "git svn" created its remote-tracking branches directly under
+refs/remotes, but it will place them under refs/remotes/origin/ unless
+it is told otherwise with its --prefix option.
+
+
+Updates since v1.8.4
+--------------------
+
+Foreign interfaces, subsystems and ports.
+
+ * "git-svn" has been taught to use the serf library, which is the
+   only option SVN 1.8.0 offers us when talking the HTTP protocol.
+
+ * "git-svn" talking over an https:// connection using the serf library
+   dumped core due to a bug in the serf library that SVN uses.  Work
+   around it on our side, even though the SVN side is being fixed.
+
+ * On MacOS X, we detected if the filesystem needs the "pre-composed
+   unicode strings" workaround, but did not automatically enable it.
+   Now we do.
+
+ * remote-hg remote helper misbehaved when interacting with a local Hg
+   repository relative to the home directory, e.g. "clone hg::~/there".
+
+ * imap-send ported to OS X uses Apple's security framework instead of
+   OpenSSL's.
+
+ * "git fast-import" treats an empty path given to "ls" as the root of
+   the tree.
+
+
+UI, Workflows & Features
+
+ * xdg-open can be used as a browser backend for "git web-browse"
+   (hence to show "git help -w" output), when available.
+
+ * "git grep" and "git show" pay attention to the "--textconv" option
+   when these commands are told to operate on blob objects (e.g. "git
+   grep -e pattern --textconv HEAD:Makefile").
+
+ * "git replace" helper no longer allows an object to be replaced with
+   another object of a different type to avoid confusion (you can
+   still manually craft such a replacement using "git update-ref", as an
+   escape hatch).
+
+ * "git status" no longer prints the dirty status information of
+   submodules for which submodule.$name.ignore is set to "all".
+
+ * "git rebase -i" honours core.abbrev when preparing the insn sheet
+   for editing.
+
+ * "git status" during a cherry-pick shows which original commit is
+   being picked.
+
+ * Instead of typing four capital letters "HEAD", you can say "@" now,
+   e.g. "git log @".
+
+ * "git check-ignore" follows the same rule as "git add" and "git
+   status" in that the ignore/exclude mechanism does not take effect
+   on paths that are already tracked.  With the "--no-index" option, it
+   can be used to diagnose which paths that should have been ignored
+   have been mistakenly added to the index.
+
+ * Some irrelevant "advice" messages that are shared with "git status"
+   output have been removed from the commit log template.
+
+ * "update-refs" learned a "--stdin" option to read multiple update
+   requests and perform them in an all-or-none fashion.
+
+ * Just like "make -C <directory>", "git -C <directory> ..." tells Git
+   to go there before doing anything else.
+
+ * Just like "git checkout -" knows to check out, and "git merge -"
+   knows to merge, the branch you were previously on, "git cherry-pick"
+   now understands "git cherry-pick -" to pick from the previous
+   branch.
+
+ * "git status" now omits the prefix to make its output a comment in a
+   commit log editor, which is not necessary for human consumption.
+   Scripts that parse the output of "git status" are advised to use
+   "git status --porcelain" instead, as its format is stable and easier
+   to parse.
+
+ * The ref syntax "foo^{tag}" (with the literal string "{tag}") peels a
+   tag ref to itself, i.e. it's a no-op., and fails if
+   "foo" is not a tag.  "git rev-parse --verify v1.0^{tag}" is
+   a more convenient way than "test $(git cat-file -t v1.0) = tag" to
+   check if v1.0 is a tag.
+
+ * "git branch -v -v" (and "git status") did not distinguish among a
+   branch that is not based on any other branch, a branch that is in
+   sync with its upstream branch, and a branch that is configured with an
+   upstream branch that no longer exists.
+
+ * Earlier we started rejecting any attempt to add the 0{40} object name to
+   the index and to tree objects, but it sometimes is necessary to
+   allow this to be able to use tools like filter-branch to correct such
+   broken tree objects.  "filter-branch" can again be used to do this.
+
+ * "git config" did not provide a way to set or access numbers larger
+   than a native "int" on the platform; it now provides 64-bit signed
+   integers on all platforms.
+
+ * "git pull --rebase" always chose to do the bog-standard flattening
+   rebase.  You can tell it to run "rebase --preserve-merges" with
+   "git pull --rebase=preserve" or by
+   setting "pull.rebase" configuration to "preserve".
+
+ * "git push --no-thin" actually disables the "thin pack transfer"
+   optimization.
+
+ * Magic pathspecs like ":(icase)makefile" (matches both Makefile
+   and makefile) and ":(glob)foo/**/bar" (matches "bar" in "foo"
+   and any subdirectory of "foo") can be used in more places.
+
+ * The "http.*" variables can now be specified for individual URLs.
+   For example,
+
+   [http]
+       sslVerify = true
+   [http "https://weak.example.com/"]
+       sslVerify = false
+
+   would flip http.sslVerify off only when talking to that specific
+   site.
+
+ * "git mv A B" when moving a submodule has been taught to
+   relocate the submodule's working tree and to adjust the paths in the
+   .gitmodules file.
+
+ * "git blame" can now take more than one -L option to discover the
+   origin of multiple blocks of lines.
+
+ * The http transport clients can optionally ask to save cookies
+   with the http.savecookies configuration variable.
+
+ * "git push" learned a more fine grained control over a blunt
+   "--force" when requesting a non-fast-forward update with the
+   "--force-with-lease=<refname>:<expected object name>" option.
+
+ * "git diff --diff-filter=<classes of changes>" can now take
+   lowercase letters (e.g. "--diff-filter=d") to mean "show
+   everything but these classes".  "git diff-files -q" is now a
+   deprecated synonym for "git diff-files --diff-filter=d".
+
+ * "git fetch" (hence "git pull" as well) learned to check
+   "fetch.prune" and "remote.*.prune" configuration variables and
+   to behave as if the "--prune" command line option was given.
+
+ * "git check-ignore -z" applied the NUL termination to both its input
+   (with --stdin) and its output, but "git check-attr -z" ignored the
+   option on the output side. Make both honor -z on the input and
+   output side the same way.
+
+ * "git whatchanged" may still be used by old timers, but mention of
+   it in documents meant for new users will only waste readers' time
+   wondering what the difference is between it and "git log".  Make it
+   less prominent in the general part of the documentation and explain
+   that it is merely a "git log" with different default behaviour in
+   its own document.
+
+
+Performance, Internal Implementation, etc.
+
+ * "git for-each-ref" when asking for merely the object name does not
+   have to parse the object pointed at by the refs; the codepath has
+   been optimized.
+
+ * The HTTP transport will try to use TCP keepalive when able.
+
+ * "git repack" is now written in C.
+
+ * Build procedure for MSVC has been updated.
+
+ * If a build-time fallback is set to "cat" instead of "less", we
+   should apply the same "no subprocess or pipe" optimization as we
+   apply to user-supplied GIT_PAGER=cat.
+
+ * Many commands use a --dashed-option as an operation mode selector
+   (e.g. "git tag --delete") that excludes other operation modes
+   (e.g. "git tag --delete --verify" is nonsense) and that cannot be
+   negated (e.g. "git tag --no-delete" is nonsense).  The parse-options
+   API learned a new OPT_CMDMODE macro to make it easier to implement
+   such a set of options.
+
+ * OPT_BOOLEAN() in the parse-options API was misdesigned to be "counting
+   up" but many subcommands expect it to behave as "on/off". Update
+   them to use OPT_BOOL() which is a proper boolean.
+
+ * "git gc" exits early without doing any work when it detects
+   that another instance of itself is already running.
+
+ * Under memory pressure and/or file descriptor pressure, we used to
+   close pack windows that are not used and also closed filehandles to
+   open but unused packfiles. These are now controlled separately
+   to better cope with the load.
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v1.8.4
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.4 in the maintenance
+track are contained in this release (see the maintenance releases' notes for
+details).
+
+ * An ancient How-To on serving Git repositories on an HTTP server
+   lacked a warning that it has been mostly superseded with a more
+   modern way.
+   (merge 6d52bc3 sc/doc-howto-dumb-http later to maint).
+
+ * The interaction between the use of Perl in our test suite and NO_PERL
+   has been clarified a bit.
+   (merge f8fc0ee jn/test-prereq-perl-doc later to maint).
+
+ * The synopsis section of the "git unpack-objects" documentation has been
+   clarified a bit.
+   (merge 61e2e22 vd/doc-unpack-objects later to maint).
+
+ * We did not generate the HTML version of the documentation to "git subtree"
+   in contrib/.
+   (merge 95c62fb jk/subtree-install-fix later to maint).
+
+ * A fast-import stream expresses a pathname with funny characters by
+   quoting them in C style; the remote-hg remote helper forgot to unquote
+   such a path.
+   (merge 1136265 ap/remote-hg-unquote-cquote later to maint).
+
+ * "git reset -p HEAD" has a codepath to special-case it to behave
+   differently from resetting to contents of other commits, but a
+   recent change broke it.
+
+ * Coloring around octopus merges in "log --graph" output was screwy.
+   (merge 339c17b hn/log-graph-color-octopus later to maint).
+
+ * "git checkout topic", when there is not yet a local "topic" branch
+   but there is a unique remote-tracking branch for a remote "topic"
+   branch, pretended as if "git checkout -t -b topic remote/$r/topic"
+   (for that unique remote $r) was run. This hack however was not
+   implemented for "git checkout topic --".
+   (merge bca3969 mm/checkout-auto-track-fix later to maint).
+
+ * One long-standing flaw in the pack transfer protocol used by "git
+   clone" was that there was no way to tell the other end which branch
+   "HEAD" points at, and the receiving end needed to guess.  A new
+   capability has been defined in the pack protocol to convey this
+   information so that cloning from a repository with more than one
+   branch pointing at the same commit where the HEAD is at now
+   reliably sets the initial branch in the resulting repository.
+   (merge 360a326 jc/upload-pack-send-symref later to maint).
+
+ * We did not handle cases where the http transport gets redirected during
+   the authorization request (e.g. from http:// to https://).
+   (merge 70900ed jk/http-auth-redirects later to maint).
+
+ * Bash prompting code to deal with an SVN remote as an upstream
+   was coded in a way unsupported by older Bash versions (3.x).
+   (merge 52ec889 sg/prompt-svn-remote-fix later to maint).
+
+ * The fall-back parsing of commit objects with broken author or
+   committer lines was less robust than ideal in picking up the
+   timestamps.
+   (merge 03818a4 jk/split-broken-ident later to maint).
+
+ * "git rev-list --objects ^v1.0^ v1.0" gave the v1.0 tag itself in the
+   output, but "git rev-list --objects v1.0^..v1.0" did not.
+   (merge 895c5ba jc/revision-range-unpeel later to maint).
+
+ * "git clone" wrote some progress messages to standard output, not
+   to standard error, and did not suppress them with the
+   --no-progress option.
+   (merge 643f918 jk/clone-progress-to-stderr later to maint).
+
+ * "format-patch --from=<whom>" forgot to omit an unnecessary in-body
+   from line, i.e. when <whom> is the same as the real author.
+   (merge 662cc30 jk/format-patch-from later to maint).
+
+ * "git shortlog" used to choke and die when there is a malformed
+   commit (e.g. missing authors); it now simply ignores such a commit
+   and keeps going.
+   (merge cd4f09e jk/shortlog-tolerate-broken-commit later to maint).
+
+ * "git merge-recursive" did not parse its "--diff-algorithm=" command
+   line option correctly.
+   (merge 6562928 jk/diff-algo later to maint).
+
+ * When running "fetch -q", a long silence while the sender side
+   computes the set of objects to send can be mistaken by proxies as
+   dropped connection.  The server side has been taught to send a
+   small empty messages to keep the connection alive.
+   (merge 115dedd jk/upload-pack-keepalive later to maint).
+
+ * "git rebase" had a portability regression in v1.8.4 that triggered a
+   bug in some BSD shell implementations.
+   (merge 99855dd mm/rebase-continue-freebsd-WB later to maint).
+
+ * "git branch --track" had a minor regression in v1.8.3.2 and later
+   that made it impossible to base your local work on anything but a
+   local branch of the upstream repository you are tracking.
+   (merge b0f49ff jh/checkout-auto-tracking later to maint).
+
+ * When the web server responds with "405 Method Not Allowed", "git
+   http-backend" should tell the client what methods are allowed with
+   the "Allow" header.
+   (merge 9247be0 bc/http-backend-allow-405 later to maint).
+
+ * When there is no sufficient overlap between old and new history
+   during a "git fetch" into a shallow repository, objects that the
+   sending side knows the receiving end has were unnecessarily sent.
+   (merge f21d2a7 nd/fetch-into-shallow later to maint).
+
+ * "git cvsserver" computed the permission mode bits incorrectly for
+   executable files.
+   (merge 1b48d56 jc/cvsserver-perm-bit-fix later to maint).
+
+ * When send-email obtains an error message to die with upon
+   failure to start an SSL session, it tried to read the error string
+   from a wrong place.
+   (merge 6cb0c88 bc/send-email-ssl-die-message-fix later to maint).
+
+ * The implementation of "add -i" has some crippling code to work around an
+   ActiveState Perl limitation but it by mistake also triggered on Git
+   for Windows where MSYS perl is used.
+   (merge df17e77 js/add-i-mingw later to maint).
+
+ * We made sure that we notice when the user-supplied GIT_DIR is actually a
+   gitfile, but did not do the same when the default ".git" is a
+   gitfile.
+   (merge 487a2b7 nd/git-dir-pointing-at-gitfile later to maint).
+
+ * When an object is not found after checking the packfiles and the
+   loose object directory, read_sha1_file() re-checks the packfiles to
+   prevent racing with a concurrent repacker; teach the same logic to
+   has_sha1_file().
+   (merge 45e8a74 jk/has-sha1-file-retry-packed later to maint).
+
+ * "git commit --author=$name", when $name is not in the canonical
+   "A. U. Thor <au.thor@example.xz>" format, looks for a matching name
+   from existing history, but did not consult mailmap to grab the
+   preferred author name.
+   (merge ea16794 ap/commit-author-mailmap later to maint).
+
+ * "git ls-files -k" needs to crawl only the part of the working tree
+   that may overlap the paths in the index to find killed files, but
+   shared code with the logic to find all the untracked files, which
+   made it unnecessarily inefficient.
+   (merge 680be04 jc/ls-files-killed-optim later to maint).
+
+ * The shortened commit object names in the insn sheet that is prepared at the
+   beginning of a "rebase -i" session can become ambiguous as the
+   rebasing progresses and the repository gains more commits. Make
+   sure the internal record is kept with full 40-hex object names.
+   (merge 75c6976 es/rebase-i-no-abbrev later to maint).
+
+ * "git rebase --preserve-merges" internally used the merge machinery
+   and as a side effect left the merge summary message in the log, but
+   when rebasing there is no need for the merge summary.
+   (merge a9f739c rt/rebase-p-no-merge-summary later to maint).
+
+ * A call to xread() was used without a loop around it to cope with short
+   reads in the codepath to stream new contents to a pack.
+   (merge e92527c js/xread-in-full later to maint).
+
+ * "git rebase -i" forgot that the comment character is
+   configurable while reading its insn sheet.
+   (merge 7bca7af es/rebase-i-respect-core-commentchar later to maint).
+
+ * The mailmap support code read past the allocated buffer when the
+   mailmap file ended with an incomplete line.
+   (merge f972a16 jk/mailmap-incomplete-line later to maint).
+
+ * We used to send a large request to read(2)/write(2) as a single
+   system call, which was bad from the latency point of view when
+   the operation needs to be killed, and also triggered an error on
+   broken 64-bit systems that refuse to read or write more than 2GB
+   in one go.
+   (merge a487916 sp/clip-read-write-to-8mb later to maint).
+
+ * "git fetch" that auto-followed tags incorrectly reused the
+   connection with Git-aware transport helper (like the sample "ext::"
+   helper shipped with Git).
+   (merge 0f73f8b jc/transport-do-not-use-connect-twice-in-fetch later to maint).
+
+ * "git log --full-diff -- <pathspec>" showed a huge diff for paths
+   outside the given <pathspec> for each commit, instead of showing
+   the change relative to the parent of the commit.  "git reflog -p"
+   had a similar problem.
+   (merge 838f9a1 tr/log-full-diff-keep-true-parents later to maint).
+
+ * Setting a submodule.*.path configuration variable to true (without
+   giving "= value") caused Git to segfault.
+   (merge 4b05440 jl/some-submodule-config-are-not-boolean later to maint).
+
+ * "git rebase -i" (there could be others, as the root cause is pretty
+   generic) fed a random, data dependent string to 'echo' and
+   expected it to come out literally, corrupting its error message.
+   (merge 89b0230 mm/no-shell-escape-in-die-message later to maint).
+
+ * Some people still use rather old versions of bash, which cannot
+   grok some constructs like 'printf -v varname' which the prompt and
+   completion code started to use recently.
+   (merge a44aa69 bc/completion-for-bash-3.0 later to maint).
+
+ * Code to read configuration from a blob object did not compile on
+   platforms with fgetc() etc. implemented as macros.
+   (merge 49d6cfa hv/config-from-blob later to maint-1.8.3).
+
+ * The recent "short-cut clone connectivity check" topic broke a
+   shallow repository when a fetch operation tries to auto-follow tags.
+   (merge 6da8bdc nd/fetch-pack-shallow-fix later to maint-1.8.3).

+Git v1.9.0 Release Notes
+========================
+
+Backward compatibility notes
+----------------------------
+
+"git submodule foreach $cmd $args" used to treat "$cmd $args" the same
+way "ssh" did, concatenating them into a single string and letting the
+shell unquote. Careless users who forget to sufficiently quote $args
+get their argument split at $IFS whitespaces by the shell, and got
+unexpected results due to this. Starting from this release, the
+command line is passed directly to the shell, if it has an argument.
+
+Read-only support for experimental loose-object format, in which users
+could optionally choose to write their loose objects for a short
+while between v1.4.3 and v1.5.3 era, has been dropped.
+
+The meanings of the "--tags" option to "git fetch" has changed; the
+command fetches tags _in addition to_ what is fetched by the same
+command line without the option.
+
+The way "git push $there $what" interprets the $what part given on the
+command line, when it does not have a colon that explicitly tells us
+what ref at the $there repository is to be updated, has been enhanced.
+
+A handful of ancient commands that have long been deprecated are
+finally gone (repo-config, tar-tree, lost-found, and peek-remote).
+
+
+Backward compatibility notes (for Git 2.0.0)
+--------------------------------------------
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  In Git 2.0, the default will change to the "simple"
+semantics, which pushes:
+
+ - only the current branch to the branch with the same name, and only
+   when the current branch is set to integrate with that remote
+   branch, if you are pushing to the same remote as you fetch from; or
+
+ - only the current branch to the branch with the same name, if you
+   are pushing to a remote that is not where you usually fetch from.
+
+Use the user preference configuration variable "push.default" to
+change this.  If you are an old-timer who is used to the "matching"
+semantics, you can set the variable to "matching" to keep the
+traditional behaviour.  If you want to live in the future early, you
+can set it to "simple" today without waiting for Git 2.0.
+
+When "git add -u" (and "git add -A") is run inside a subdirectory and
+does not specify which paths to add on the command line, it
+will operate on the entire tree in Git 2.0 for consistency
+with "git commit -a" and other commands.  There will be no
+mechanism to make plain "git add -u" behave like "git add -u .".
+Current users of "git add -u" (without a pathspec) should start
+training their fingers to explicitly say "git add -u ."
+before Git 2.0 comes.  A warning is issued when these commands are
+run without a pathspec and when you have local changes outside the
+current directory, because the behaviour in Git 2.0 will be different
+from today's version in such a situation.
+
+In Git 2.0, "git add <path>" will behave as "git add -A <path>", so
+that "git add dir/" will notice paths you removed from the directory
+and record the removal.  Versions before Git 2.0, including this
+release, will keep ignoring removals, but the users who rely on this
+behaviour are encouraged to start using "git add --ignore-removal <path>"
+now before 2.0 is released.
+
+The default prefix for "git svn" will change in Git 2.0.  For a long
+time, "git svn" created its remote-tracking branches directly under
+refs/remotes, but it will place them under refs/remotes/origin/ unless
+it is told otherwise with its --prefix option.
+
+
+Updates since v1.8.5
+--------------------
+
+Foreign interfaces, subsystems and ports.
+
+ * The HTTP transport, when talking GSS-Negotiate, uses "100
+   Continue" response to avoid having to rewind and resend a large
+   payload, which may not be always doable.
+
+ * Various bugfixes to remote-bzr and remote-hg (in contrib/).
+
+ * The build procedure is aware of MirBSD now.
+
+ * Various "git p4", "git svn" and "gitk" updates.
+
+
+UI, Workflows & Features
+
+ * Fetching from a shallowly-cloned repository used to be forbidden,
+   primarily because the codepaths involved were not carefully vetted
+   and we did not bother supporting such usage. This release attempts
+   to allow object transfer out of a shallowly-cloned repository in a
+   more controlled way (i.e. the receiver becomes a shallow repository
+   with a truncated history).
+
+ * Just like we give a reasonable default for "less" via the LESS
+   environment variable, we now specify a reasonable default for "lv"
+   via the "LV" environment variable when spawning the pager.
+
+ * Two-level configuration variable names in "branch.*" and "remote.*"
+   hierarchies, whose variables are predominantly three-level, were
+   not completed by hitting a <TAB> in bash and zsh completions.
+
+ * Fetching a 'frotz' branch with "git fetch", while a 'frotz/nitfol'
+   remote-tracking branch from an earlier fetch was still there, would
+   error out, primarily because the command was not told that it is
+   allowed to lose any information on our side.  "git fetch --prune"
+   now can be used to remove 'frotz/nitfol' to make room for fetching and
+   storing the 'frotz' remote-tracking branch.
+
+ * "diff.orderfile=<file>" configuration variable can be used to
+   pretend as if the "-O<file>" option were given from the command
+   line of "git diff", etc.
+
+ * The negative pathspec syntax allows "git log -- . ':!dir'" to tell
+   us "I am interested in everything but 'dir' directory".
+
+ * "git difftool" shows how many different paths there are in total,
+   and how many of them have been shown so far, to indicate progress.
+
+ * "git push origin master" used to push our 'master' branch to update
+   the 'master' branch at the 'origin' repository.  This has been
+   enhanced to use the same ref mapping "git push origin" would use to
+   determine what ref at the 'origin' to be updated with our 'master'.
+   For example, with this configuration
+
+   [remote "origin"]
+      push = refs/heads/*:refs/review/*
+
+   that would cause "git push origin" to push out our local branches
+   to corresponding refs under refs/review/ hierarchy at 'origin',
+   "git push origin master" would update 'refs/review/master' over
+   there.  Alternatively, if push.default is set to 'upstream' and our
+   'master' is set to integrate with 'topic' from the 'origin' branch,
+   running "git push origin" while on our 'master' would update their
+   'topic' branch, and running "git push origin master" while on any
+   of our branches does the same.
+
+ * "gitweb" learned to treat ref hierarchies other than refs/heads as
+   if they are additional branch namespaces (e.g. refs/changes/ in
+   Gerrit).
+
+ * "git for-each-ref --format=..." learned a few formatting directives;
+   e.g. "%(color:red)%(HEAD)%(color:reset) %(refname:short) %(subject)".
+
+ * The command string given to "git submodule foreach" is passed
+   directly to the shell, without being eval'ed.  This is a backward
+   incompatible change that may break existing users.
+
+ * "git log" and friends learned the "--exclude=<glob>" option, to
+   allow people to say "list history of all branches except those that
+   match this pattern" with "git log --exclude='*/*' --branches".
+
+ * "git rev-parse --parseopt" learned a new "--stuck-long" option to
+   help scripts parse options with an optional parameter.
+
+ * The "--tags" option to "git fetch" no longer tells the command to
+   fetch _only_ the tags. It instead fetches tags _in addition to_
+   what are fetched by the same command line without the option.
+
+
+Performance, Internal Implementation, etc.
+
+ * When parsing a 40-hex string into the object name, the string is
+   checked to see if it can be interpreted as a ref so that a warning
+   can be given for ambiguity. The code kicked in even when the
+   core.warnambiguousrefs is set to false to squelch this warning, in
+   which case the cycles spent to look at the ref namespace were an
+   expensive no-op, as the result was discarded without being used.
+
+ * The naming convention of the packfiles has been updated; it used to
+   be based on the enumeration of names of the objects that are
+   contained in the pack, but now it also depends on how the packed
+   result is represented---packing the same set of objects using
+   different settings (or delta order) would produce a pack with
+   different name.
+
+ * "git diff --no-index" mode used to unnecessarily attempt to read
+   the index when there is one.
+
+ * The deprecated parse-options macro OPT_BOOLEAN has been removed;
+   use OPT_BOOL or OPT_COUNTUP in new code.
+
+ * A few duplicate implementations of prefix/suffix string comparison
+   functions have been unified to starts_with() and ends_with().
+
+ * The new PERLLIB_EXTRA makefile variable can be used to specify
+   additional directories Perl modules (e.g. the ones necessary to run
+   git-svn) are installed on the platform when building.
+
+ * "git merge-base" learned the "--fork-point" mode, that implements
+   the same logic used in "git pull --rebase" to find a suitable fork
+   point out of the reflog entries for the remote-tracking branch the
+   work has been based on.  "git rebase" has the same logic that can be
+   triggered with the "--fork-point" option.
+
+ * A third-party "receive-pack" (the responder to "git push") can
+   advertise the "no-thin" capability to tell "git push" not to use
+   the thin-pack optimization. Our receive-pack has always been
+   capable of accepting and fattening a thin-pack, and will continue
+   not to ask "git push" to use a non-thin pack.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v1.8.5
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.5 in the maintenance
+track are contained in this release (see the maintenance releases' notes
+for details).
+
+ * The pathspec matching code, while comparing two trees (e.g. "git
+   diff A B -- path1 path2") was too aggressive and failed to match
+   some paths when multiple pathspecs were involved.
+
+ * "git repack --max-pack-size=8g" stopped being parsed correctly when
+   the command was reimplemented in C.
+
+ * An earlier update in v1.8.4.x to "git rev-list --objects" with
+   negative ref had a performance regression.
+   (merge 200abe7 jk/mark-edges-uninteresting later to maint).
+
+ * A recent update to "git send-email" broke platforms where
+   /etc/ssl/certs/ directory exists but cannot be used as SSL_ca_path
+   (e.g. Fedora rawhide).
+
+ * A handful of bugs around interpreting $branch@{upstream} notation
+   and its lookalike, when $branch part has interesting characters,
+   e.g. "@", and ":", have been fixed.
+
+ * "git clone" would fail to clone from a repository that has a ref
+   directly under "refs/", e.g. "refs/stash", because different
+   validation paths do different things on such a refname.  Loosen the
+   client side's validation to allow such a ref.
+
+ * "git log --left-right A...B" lost the "leftness" of commits
+   reachable from A when A is a tag as a side effect of a recent
+   bugfix.  This is a regression in 1.8.4.x series.
+
+ * documentations to "git pull" hinted there is an "-m" option because
+   it incorrectly shared the documentation with "git merge".
+
+ * "git diff A B submod" and "git diff A B submod/" ought to have done
+   the same for a submodule "submod", but didn't.
+
+ * "git clone $origin foo\bar\baz" on Windows failed to create the
+   leading directories (i.e. a moral-equivalent of "mkdir -p").
+
+ * "submodule.*.update=checkout", when propagated from .gitmodules to
+   .git/config, turned into a "submodule.*.update=none", which did not
+   make much sense.
+   (merge efa8fd7 fp/submodule-checkout-mode later to maint).
+
+ * The implementation of 'git stash $cmd "stash@{...}"' did not quote
+   the stash argument properly and left it split at IFS whitespace.
+
+ * The "--[no-]informative-errors" options to "git daemon" were parsed
+   a bit too loosely, allowing any other string after these option
+   names.
+
+ * There is no reason to have a hardcoded upper limit for the number of
+   parents of an octopus merge, created via the graft mechanism, but
+   there was.
+
+ * The basic test used to leave unnecessary trash directories in the
+   t/ directory.
+   (merge 738a8be jk/test-framework-updates later to maint).
+
+ * "git merge-base --octopus" used to leave cleaning up suboptimal
+   result to the caller, but now it does the clean-up itself.
+
+ * A "gc" process running as a different user should be able to stop a
+   new "gc" process from starting, but it didn't.
+
+ * An earlier "clean-up" introduced an unnecessary memory leak.
+
+ * "git add -A" (no other arguments) in a totally empty working tree
+   used to emit an error.
+
+ * "git log --decorate" did not handle a tag pointed by another tag
+   nicely.
+
+ * When we figure out how many file descriptors to allocate for
+   keeping packfiles open, a system with non-working getrlimit() could
+   cause us to die(), but because we make this call only to get a
+   rough estimate of how many are available and we do not even attempt
+   to use up all available file descriptors ourselves, it is nicer to
+   fall back to a reasonable low value rather than dying.
+
+ * read_sha1_file(), that is the workhorse to read the contents given
+   an object name, honoured object replacements, but there was no
+   corresponding mechanism to sha1_object_info() that was used to
+   obtain the metainfo (e.g. type & size) about the object.  This led
+   callers to weird inconsistencies.
+   (merge 663a856 cc/replace-object-info later to maint).
+
+ * "git cat-file --batch=", an admittedly useless command, did not
+   behave very well.
+
+ * "git rev-parse <revs> -- <paths>" did not implement the usual
+   disambiguation rules the commands in the "git log" family used in
+   the same way.
+
+ * "git mv A B/", when B does not exist as a directory, should error
+   out, but it didn't.
+
+ * A workaround to an old bug in glibc prior to glibc 2.17 has been
+   retired; this would remove a side effect of the workaround that
+   corrupts system error messages in non-C locales.
+
+ * SSL-related options were not passed correctly to underlying socket
+   layer in "git send-email".
+
+ * "git commit -v" appends the patch to the log message before
+   editing, and then removes the patch when the editor returned
+   control. However, the patch was not stripped correctly when the
+   first modified path was a submodule.
+
+ * "git fetch --depth=0" was a no-op, and was silently ignored.
+   Diagnose it as an error.
+
+ * Remote repository URLs expressed in scp-style host:path notation are
+   parsed more carefully (e.g. "foo/bar:baz" is local, "[::1]:/~user" asks
+   to connect to user's home directory on host at address ::1.
+
+ * "git diff -- ':(icase)makefile'" was unnecessarily rejected at the
+   command line parser.
+
+ * "git cat-file --batch-check=ok" did not check the existence of
+   the named object.
+
+ * "git am --abort" sometimes complained about not being able to write
+   a tree with an 0{40} object in it.
+
+ * Two processes creating loose objects at the same time could have
+   failed unnecessarily when the name of their new objects started
+   with the same byte value, due to a race condition.

+Git v1.9.1 Release Notes
+========================
+
+Fixes since v1.9.0
+------------------
+
+ * "git clean -d pathspec" did not use the given pathspec correctly
+   and ended up cleaning too much.
+
+ * "git difftool" misbehaved when the repository is bound to the
+   working tree with the ".git file" mechanism, where a textual file
+   ".git" tells us where it is.
+
+ * "git push" did not pay attention to branch.*.pushremote if it is
+   defined earlier than remote.pushdefault; the order of these two
+   variables in the configuration file should not matter, but it did
+   by mistake.
+
+ * Codepaths that parse timestamps in commit objects have been
+   tightened.
+
+ * "git diff --external-diff" incorrectly fed the submodule directory
+   in the working tree to the external diff driver when it knew it is
+   the same as one of the versions being compared.
+
+ * "git reset" needs to refresh the index when working in a working
+   tree (it can also be used to match the index to the HEAD in an
+   otherwise bare repository), but it failed to set up the working
+   tree properly, causing GIT_WORK_TREE to be ignored.
+
+ * "git check-attr" when working on a repository with a working tree
+   did not work well when the working tree was specified via the
+   --work-tree (and obviously with --git-dir) option.
+
+ * "merge-recursive" was broken in 1.7.7 era and stopped working in
+   an empty (temporary) working tree, when there are renames
+   involved.  This has been corrected.
+
+ * "git rev-parse" was loose in rejecting command line arguments
+   that do not make sense, e.g. "--default" without the required
+   value for that option.
+
+ * include.path variable (or any variable that expects a path that
+   can use ~username expansion) in the configuration file is not a
+   boolean, but the code failed to check it.
+
+ * "git diff --quiet -- pathspec1 pathspec2" sometimes did not return
+   correct status value.
+
+ * Attempting to deepen a shallow repository by fetching over smart
+   HTTP transport failed in the protocol exchange, when no-done
+   extension was used.  The fetching side waited for the list of
+   shallow boundary commits after the sending end stopped talking to
+   it.
+
+ * Allow "git cmd path/", when the 'path' is where a submodule is
+   bound to the top-level working tree, to match 'path', despite the
+   extra and unnecessary trailing slash (such a slash is often
+   given by command line completion).

+Git v1.9.2 Release Notes
+========================
+
+Fixes since v1.9.1
+------------------
+
+ * Documentation and in-code comments had many instances of mistaken
+   use of "nor", which have been corrected.
+
+ * "git fetch --prune", when the right-hand-side of multiple fetch
+   refspecs overlap (e.g. storing "refs/heads/*" to
+   "refs/remotes/origin/*", while storing "refs/frotz/*" to
+   "refs/remotes/origin/fr/*"), aggressively thought that lack of
+   "refs/heads/fr/otz" on the origin site meant we should remove
+   "refs/remotes/origin/fr/otz" from us, without checking their
+   "refs/frotz/otz" first.
+
+   Note that such a configuration is inherently unsafe (think what
+   should happen when "refs/heads/fr/otz" does appear on the origin
+   site), but that is not a reason not to be extra careful.
+
+ * "git update-ref --stdin" did not fail a request to create a ref
+   when the ref already existed.
+
+ * "git diff --no-index -Mq a b" fell into an infinite loop.
+
+ * When it is not necessary to edit a commit log message (e.g. "git
+   commit -m" is given a message without specifying "-e"), we used to
+   disable the spawning of the editor by overriding GIT_EDITOR, but
+   this means all the uses of the editor, other than to edit the
+   commit log message, are also affected.
+
+ * "git status --porcelain --branch" showed its output with labels
+   "ahead/behind/gone" translated to the user's locale.
+
+ * "git mv" that moves a submodule forgot to adjust the array that
+   uses to keep track of which submodules were to be moved to update
+   its configuration.
+
+ * Length limit for the pathname used when removing a path in a deep
+   subdirectory has been removed to avoid buffer overflows.
+
+ * The test helper lib-terminal always run an actual test_expect_*
+   when included, which screwed up with the use of skil-all that may
+   have to be done later.
+
+ * "git index-pack" used a wrong variable to name the keep-file in an
+   error message when the file cannot be written or closed.
+
+ * "rebase -i" produced a broken insn sheet when the title of a commit
+   happened to contain '\n' (or ended with '\c') due to a careless use
+   of 'echo'.
+
+ * There were a few instances of 'git-foo' remaining in the
+   documentation that should have been spelled 'git foo'.
+
+ * Serving objects from a shallow repository needs to write a
+   new file to hold the temporary shallow boundaries but it was not
+   cleaned when we exit due to die() or a signal.
+
+ * When "git stash pop" stops after failing to apply the stash
+   (e.g. due to conflicting changes), the stash is not dropped. State
+   that explicitly in the output to let the users know.
+
+ * The labels in "git status" output that describe the nature of
+   conflicts (e.g. "both deleted") were limited to 20 bytes, which was
+   too short for some l10n (e.g. fr).

+
+ * The shell prompt script (in contrib/), when using the PROMPT_COMMAND

+
+ * We used to allow committing a path ".Git/config" with Git that is
+   running on a case sensitive filesystem, but an attempt to check out
+   such a path with Git that runs on a case insensitive filesystem
+   would have clobbered ".git/config", which is definitely not what

+   a path with ".Git" (in any case combination) as a path component.
+
+ * On Windows, certain path components that are different from ".git"
+   are mapped to ".git", e.g. "git~1/config" is treated as if it were
+   ".git/config".  HFS+ has a similar issue, where certain unicode
+   codepoints are ignored, e.g. ".g\u200cit/config" is treated as if
+   it were ".git/config".  Pathnames with these potential issues are
+   rejected on the affected systems.  Git on systems that are not
+   affected by this issue (e.g. Linux) can also be configured to
+   reject them to ensure cross platform interoperability of the hosted
+   projects.
+
+ * "git fsck" notices a tree object that records such a path that can
+   be confused with ".git", and with receive.fsckObjects configuration
+   set to true, an attempt to "git push" such a tree object will be
+   rejected.  Such a path may not be a problem on a well behaving
+   filesystem but in order to protect those on HFS+ and on case
+   insensitive filesystems, this check is enabled on all platforms.
+
+A big "thanks!" for bringing this issue to us goes to our friends in
+the Mercurial land, namely, Matt Mackall and Augie Fackler.

+Git v2.0 Release Notes
+======================
+
+Backward compatibility notes
+----------------------------
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  In Git 2.0, the default is now the "simple" semantics,
+which pushes:
+
+ - only the current branch to the branch with the same name, and only
+   when the current branch is set to integrate with that remote
+   branch, if you are pushing to the same remote as you fetch from; or
+
+ - only the current branch to the branch with the same name, if you
+   are pushing to a remote that is not where you usually fetch from.
+
+You can use the configuration variable "push.default" to change
+this.  If you are an old-timer who wants to keep using the
+"matching" semantics, you can set the variable to "matching", for
+example.  Read the documentation for other possibilities.
+
+When "git add -u" and "git add -A" are run inside a subdirectory
+without specifying which paths to add on the command line, they
+operate on the entire tree for consistency with "git commit -a" and
+other commands (these commands used to operate only on the current
+subdirectory).  Say "git add -u ." or "git add -A ." if you want to
+limit the operation to the current directory.
+
+"git add <path>" is the same as "git add -A <path>" now, so that
+"git add dir/" will notice paths you removed from the directory and
+record the removal.  In older versions of Git, "git add <path>" used
+to ignore removals.  You can say "git add --ignore-removal <path>" to
+add only added or modified paths in <path>, if you really want to.
+
+The "-q" option to "git diff-files", which does *NOT* mean "quiet",
+has been removed (it told Git to ignore deletion, which you can do
+with "git diff-files --diff-filter=d").
+
+"git request-pull" lost a few "heuristics" that often led to mistakes.
+
+The default prefix for "git svn" has changed in Git 2.0.  For a long
+time, "git svn" created its remote-tracking branches directly under
+refs/remotes, but it now places them under refs/remotes/origin/ unless
+it is told otherwise with its "--prefix" option.
+
+
+Updates since v1.9 series
+-------------------------
+
+UI, Workflows & Features
+
+ * The "multi-mail" post-receive hook (in contrib/) has been updated
+   to a more recent version from upstream.
+
+ * The "remote-hg/bzr" remote-helper interfaces (used to be in
+   contrib/) are no more.  They are now maintained separately as
+   third-party plug-ins in their own repositories.
+
+ * "git gc --aggressive" learned "--depth" option and
+   "gc.aggressiveDepth" configuration variable to allow use of a less
+   insane depth than the built-in default value of 250.
+
+ * "git log" learned the "--show-linear-break" option to show where a
+   single strand-of-pearls is broken in its output.
+
+ * The "rev-parse --parseopt" mechanism used by scripted Porcelains to
+   parse command-line options and to give help text learned to take
+   the argv-help (the placeholder string for an option parameter,
+   e.g. "key-id" in "--gpg-sign=<key-id>").
+
+ * The pattern to find where the function begins in C/C++ used in
+   "diff" and "grep -p" has been updated to improve viewing C++
+   sources.
+
+ * "git rebase" learned to interpret a lone "-" as "@{-1}", the
+   branch that we were previously on.
+
+ * "git commit --cleanup=<mode>" learned a new mode, scissors.
+
+ * "git tag --list" output can be sorted using "version sort" with
+   "--sort=version:refname".
+
+ * Discard the accumulated "heuristics" to guess from which branch the
+   result wants to be pulled from and make sure that what the end user
+   specified is not second-guessed by "git request-pull", to avoid
+   mistakes.  When you pushed out your 'master' branch to your public
+   repository as 'for-linus', use the new "master:for-linus" syntax to
+   denote the branch to be pulled.
+
+ * "git grep" learned to behave in a way similar to native grep when
+   "-h" (no header) and "-c" (count) options are given.
+
+ * "git push" via transport-helper interface has been updated to
+   allow forced ref updates in a way similar to the natively
+   supported transports.
+
+ * The "simple" mode is the default for "git push".
+
+ * "git add -u" and "git add -A", when run without any pathspec, is a
+   tree-wide operation even when run inside a subdirectory of a
+   working tree.
+
+ * "git add <path>" is the same as "git add -A <path>" now.
+
+ * "core.statinfo" configuration variable, which is a
+   never-advertised synonym to "core.checkstat", has been removed.
+
+ * The "-q" option to "git diff-files", which does *NOT* mean
+   "quiet", has been removed (it told Git to ignore deletion, which
+   you can do with "git diff-files --diff-filter=d").
+
+ * Server operators can loosen the "tips of refs only" restriction for
+   the remote archive service with the uploadarchive.allowUnreachable
+   configuration option.
+
+ * The progress indicators from various time-consuming commands have
+   been marked for i18n/l10n.
+
+ * "git notes -C <blob>" diagnoses as an error an attempt to use an
+   object that is not a blob.
+
+ * "git config" learned to read from the standard input when "-" is
+   given as the value to its "--file" parameter (attempting an
+   operation to update the configuration in the standard input is
+   rejected, of course).
+
+ * Trailing whitespaces in .gitignore files, unless they are quoted
+   for fnmatch(3), e.g. "path\ ", are warned and ignored.  Strictly
+   speaking, this is a backward-incompatible change, but very unlikely
+   to bite any sane user and adjusting should be obvious and easy.
+
+ * Many commands that create commits, e.g. "pull" and "rebase",
+   learned to take the "--gpg-sign" option on the command line.
+
+ * "git commit" can be told to always GPG sign the resulting commit
+   by setting the "commit.gpgsign" configuration variable to "true"
+   (the command-line option "--no-gpg-sign" should override it).
+
+ * "git pull" can be told to only accept fast-forward by setting the
+   new "pull.ff" configuration variable.
+
+ * "git reset" learned the "-N" option, which does not reset the index
+   fully for paths the index knows about but the tree-ish the command
+   resets to does not (these paths are kept as intend-to-add entries).
+
+
+Performance, Internal Implementation, etc.
+
+ * The compilation options to port to AIX and to MSVC have been
+   updated.
+
+ * We started using wildmatch() in place of fnmatch(3) a few releases
+   ago; complete the process and stop using fnmatch(3).
+
+ * Uses of curl's "multi" interface and "easy" interface do not mix
+   well when we attempt to reuse outgoing connections.  Teach the RPC
+   over HTTP code, used in the smart HTTP transport, not to use the
+   "easy" interface.
+
+ * The bitmap-index feature from JGit has been ported, which should
+   significantly improve performance when serving objects from a
+   repository that uses it.
+
+ * The way "git log --cc" shows a combined diff against multiple
+   parents has been optimized.
+
+ * The prefixcmp() and suffixcmp() functions are gone.  Use
+   starts_with() and ends_with(), and also consider if skip_prefix()
+   suits your needs better when using the former.
+
+
+Also contains various documentation updates and code clean-ups.  Many
+of them came from flurry of activities as GSoC candidate microproject
+exercises.
+
+
+Fixes since v1.9 series
+-----------------------
+
+Unless otherwise noted, all the fixes since v1.9 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * "git p4" was broken in 1.9 release to deal with changes in binary
+   files.
+   (merge 749b668 cl/p4-use-diff-tree later to maint).
+
+ * The shell prompt script (in contrib/), when using the PROMPT_COMMAND
+   interface, used an unsafe construct when showing the branch name in
+   $PS1.
+   (merge 1e4119c8 rh/prompt-pcmode-avoid-eval-on-refname later to maint).
+
+ * "git rebase" used a POSIX shell construct FreeBSD's /bin/sh does not
+   work well with.
+   (merge 8cd6596 km/avoid-non-function-return-in-rebase later to maint).
+
+ * zsh prompt (in contrib/) leaked unnecessary error messages.
+
+ * Bash completion (in contrib/) did not complete the refs and remotes
+   correctly given "git pu<TAB>" when "pu" is aliased to "push".
+
+ * Some more Unicode code points, defined in Unicode 6.3 as having zero
+   width, have been taught to our display column counting logic.
+   (merge d813ab9 tb/unicode-6.3-zero-width later to maint).
+
+ * Some tests used shell constructs that did not work well on FreeBSD
+   (merge ff7a1c6 km/avoid-bs-in-shell-glob later to maint).
+   (merge 00764ca km/avoid-cp-a later to maint).
+
+ * "git update-ref --stdin" did not fail a request to create a ref
+   when the ref already existed.
+   (merge b9d56b5 mh/update-ref-batch-create-fix later to maint).
+
+ * "git diff --no-index -Mq a b" fell into an infinite loop.
+   (merge ad1c3fb jc/fix-diff-no-index-diff-opt-parse later to maint).
+
+ * "git fetch --prune", when the right-hand side of multiple fetch
+   refspecs overlap (e.g. storing "refs/heads/*" to
+   "refs/remotes/origin/*", while storing "refs/frotz/*" to
+   "refs/remotes/origin/fr/*"), aggressively thought that lack of
+   "refs/heads/fr/otz" on the origin site meant we should remove
+   "refs/remotes/origin/fr/otz" from us, without checking their
+   "refs/frotz/otz" first.
+
+   Note that such a configuration is inherently unsafe (think what
+   should happen when "refs/heads/fr/otz" does appear on the origin
+   site), but that is not a reason not to be extra careful.
+   (merge e6f6371 cn/fetch-prune-overlapping-destination later to maint).
+
+ * "git status --porcelain --branch" showed its output with labels
+   "ahead/behind/gone" translated to the user's locale.
+   (merge 7a76c28 mm/status-porcelain-format-i18n-fix later to maint).
+
+ * A stray environment variable $prefix could have leaked into and
+   affected the behaviour of the "subtree" script (in contrib/).
+
+ * When it is not necessary to edit a commit log message (e.g. "git
+   commit -m" is given a message without specifying "-e"), we used to
+   disable the spawning of the editor by overriding GIT_EDITOR, but
+   this means all the uses of the editor, other than to edit the
+   commit log message, are also affected.
+   (merge b549be0 bp/commit-p-editor later to maint).
+
+ * "git mv" that moves a submodule forgot to adjust the array that
+   uses to keep track of which submodules were to be moved to update
+   its configuration.
+   (merge fb8a4e8 jk/mv-submodules-fix later to maint).
+
+ * Length limit for the pathname used when removing a path in a deep
+   subdirectory has been removed to avoid buffer overflows.
+   (merge 2f29e0c mh/remove-subtree-long-pathname-fix later to maint).
+
+ * The test helper lib-terminal always run an actual test_expect_*
+   when included, which screwed up with the use of skil-all that may
+   have to be done later.
+   (merge 7e27173 jk/lib-terminal-lazy later to maint).
+
+ * "git index-pack" used a wrong variable to name the keep-file in an
+   error message when the file cannot be written or closed.
+   (merge de983a0 nd/index-pack-error-message later to maint).
+
+ * "rebase -i" produced a broken insn sheet when the title of a commit
+   happened to contain '\n' (or ended with '\c') due to a careless use
+   of 'echo'.
+   (merge cb1aefd us/printf-not-echo later to maint).
+
+ * There were a few instances of 'git-foo' remaining in the
+   documentation that should have been spelled 'git foo'.
+   (merge 3c3e6f5 rr/doc-merge-strategies later to maint).
+
+ * Serving objects from a shallow repository needs to write a
+   new file to hold the temporary shallow boundaries, but it was not
+   cleaned when we exit due to die() or a signal.
+   (merge 7839632 jk/shallow-update-fix later to maint).
+
+ * When "git stash pop" stops after failing to apply the stash
+   (e.g. due to conflicting changes), the stash is not dropped. State
+   that explicitly in the output to let the users know.
+   (merge 2d4c993 jc/stash-pop-not-popped later to maint).
+
+ * The labels in "git status" output that describe the nature of
+   conflicts (e.g. "both deleted") were limited to 20 bytes, which was
+   too short for some l10n (e.g. fr).
+   (merge c7cb333 jn/wt-status later to maint).
+
+ * "git clean -d pathspec" did not use the given pathspec correctly
+   and ended up cleaning too much.
+   (merge 1f2e108 jk/clean-d-pathspec later to maint).
+
+ * "git difftool" misbehaved when the repository is bound to the
+   working tree with the ".git file" mechanism, where a textual file
+   ".git" tells us where it is.
+   (merge fcfec8b da/difftool-git-files later to maint).
+
+ * "git push" did not pay attention to "branch.*.pushremote" if it is
+   defined earlier than "remote.pushdefault"; the order of these two
+   variables in the configuration file should not matter, but it did
+   by mistake.
+   (merge 98b406f jk/remote-pushremote-config-reading later to maint).
+
+ * Code paths that parse timestamps in commit objects have been
+   tightened.
+   (merge f80d1f9 jk/commit-dates-parsing-fix later to maint).
+
+ * "git diff --external-diff" incorrectly fed the submodule directory
+   in the working tree to the external diff driver when it knew that it
+   is the same as one of the versions being compared.
+   (merge aba4727 tr/diff-submodule-no-reuse-worktree later to maint).
+
+ * "git reset" needs to refresh the index when working in a working
+   tree (it can also be used to match the index to the HEAD in an
+   otherwise bare repository), but it failed to set up the working
+   tree properly, causing GIT_WORK_TREE to be ignored.
+   (merge b7756d4 nd/reset-setup-worktree later to maint).
+
+ * "git check-attr" when working on a repository with a working tree
+   did not work well when the working tree was specified via the
+   "--work-tree" (and obviously with "--git-dir") option.
+   (merge cdbf623 jc/check-attr-honor-working-tree later to maint).
+
+ * "merge-recursive" was broken in 1.7.7 era and stopped working in
+   an empty (temporary) working tree, when there are renames
+   involved.  This has been corrected.
+   (merge 6e2068a bk/refresh-missing-ok-in-merge-recursive later to maint.)
+
+ * "git rev-parse" was loose in rejecting command-line arguments
+   that do not make sense, e.g. "--default" without the required
+   value for that option.
+   (merge a43219f ds/rev-parse-required-args later to maint.)
+
+ * "include.path" variable (or any variable that expects a path that
+   can use ~username expansion) in the configuration file is not a
+   boolean, but the code failed to check it.
+   (merge 67beb60 jk/config-path-include-fix later to maint.)
+
+ * Commands that take pathspecs on the command line misbehaved when
+   the pathspec is given as an absolute pathname (which is a
+   practice not particularly encouraged) that points at a symbolic
+   link in the working tree.
+   (merge 6127ff6 mw/symlinks later to maint.)
+
+ * "git diff --quiet -- pathspec1 pathspec2" sometimes did not return
+   the correct status value.
+   (merge f34b205 nd/diff-quiet-stat-dirty later to maint.)
+
+ * Attempting to deepen a shallow repository by fetching over smart
+   HTTP transport failed in the protocol exchange, when the no-done
+   extension was used.  The fetching side waited for the list of
+   shallow boundary commits after the sending side stopped talking to
+   it.
+   (merge 0232852 nd/http-fetch-shallow-fix later to maint.)
+
+ * Allow "git cmd path/", when the 'path' is where a submodule is
+   bound to the top-level working tree, to match 'path', despite the
+   extra and unnecessary trailing slash (such a slash is often
+   given by command-line completion).
+   (merge 2e70c01 nd/submodule-pathspec-ending-with-slash later to maint.)
+
+ * Documentation and in-code comments had many instances of mistaken
+   use of "nor", which have been corrected.
+   (merge 235e8d5 jl/nor-or-nand-and later to maint).

+Git v2.0.1 Release Notes
+========================
+
+ * We used to unconditionally disable the pager in the pager process
+   we spawn to feed out output, but that prevented people who want to
+   run "less" within "less" from doing so.
+
+ * Tools that read diagnostic output in our standard error stream do
+   not want to see terminal control sequence (e.g. erase-to-eol).
+   Detect them by checking if the standard error stream is connected
+   to a tty.
+ * Reworded the error message given upon a failure to open an existing
+   loose object file due to e.g. permission issues; it was reported as
+   the object being corrupt, but that is not quite true.
+
+ * "git log -2master" is a common typo that shows two commits starting
+   from whichever random branch that is not 'master' that happens to
+   be checked out currently.
+
+ * The "%<(10,trunc)%s" pretty format specifier in the log family of
+   commands is used to truncate the string to a given length (e.g. 10
+   in the example) with padding to column-align the output, but did
+   not take into account that number of bytes and number of display
+   columns are different.
+
+ * The "mailmap.file" configuration option did not support the tilde
+   expansion (i.e. ~user/path and ~/path).
+
+ * The completion scripts (in contrib/) did not know about quite a few
+   options that are common between "git merge" and "git pull", and a
+   couple of options unique to "git merge".
+
+ * "--ignore-space-change" option of "git apply" ignored the spaces
+   at the beginning of line too aggressively, which is inconsistent
+   with the option of the same name "diff" and "git diff" have.
+
+ * "git blame" miscounted number of columns needed to show localized
+   timestamps, resulting in jaggy left-side-edge of the source code
+   lines in its output.
+
+ * "git blame" assigned the blame to the copy in the working-tree if
+   the repository is set to core.autocrlf=input and the file used CRLF
+   line endings.
+
+ * "git commit --allow-empty-message -C $commit" did not work when the
+   commit did not have any log message.
+
+ * "git diff --find-copies-harder" sometimes pretended as if the mode
+   bits have changed for paths that are marked with assume-unchanged
+   bit.
+
+ * "git format-patch" did not enforce the rule that the "--follow"
+   option from the log/diff family of commands must be used with
+   exactly one pathspec.
+
+ * "git gc --auto" was recently changed to run in the background to
+   give control back early to the end-user sitting in front of the
+   terminal, but it forgot that housekeeping involving reflogs should
+   be done without other processes competing for accesses to the refs.
+
+ * "git grep -O" to show the lines that hit in the pager did not work
+   well with case insensitive search.  We now spawn "less" with its
+   "-I" option when it is used as the pager (which is the default).
+
+ * We used to disable threaded "git index-pack" on platforms without
+   thread-safe pread(); use a different workaround for such
+   platforms to allow threaded "git index-pack".
+
+ * The error reporting from "git index-pack" has been improved to
+   distinguish missing objects from type errors.
+
+ * "git mailinfo" used to read beyond the end of header string while
+   parsing an incoming e-mail message to extract the patch.
+
+ * On a case insensitive filesystem, merge-recursive incorrectly
+   deleted the file that is to be renamed to a name that is the same
+   except for case differences.
+
+ * "git pack-objects" unnecessarily copied the previous contents when
+   extending the hashtable, even though it will populate the table
+   from scratch anyway.
+
+ * "git rerere forget" did not work well when merge.conflictstyle
+   was set to a non-default value.
+
+ * "git remote rm" and "git remote prune" can involve removing many
+   refs at once, which is not a very efficient thing to do when very
+   many refs exist in the packed-refs file.
+
+ * "git log --exclude=<glob> --all | git shortlog" worked as expected,
+   but "git shortlog --exclude=<glob> --all", which is supposed to be
+   identical to the above pipeline, was not accepted at the command
+   line argument parser level.
+
+ * The autostash mode of "git rebase -i" did not restore the dirty
+   working tree state if the user aborted the interactive rebase by
+   emptying the insn sheet.
+
+ * "git show -s" (i.e. show log message only) used to incorrectly emit
+   an extra blank line after a merge commit.
+
+ * "git status", even though it is a read-only operation, tries to
+   update the index with refreshed lstat(2) info to optimize future
+   accesses to the working tree opportunistically, but this could
+   race with a "read-write" operation that modify the index while it
+   is running.  Detect such a race and avoid overwriting the index.
+
+ * "git status" (and "git commit") behaved as if changes in a modified
+   submodule are not there if submodule.*.ignore configuration is set,
+   which was misleading.  The configuration is only to unclutter diff
+   output during the course of development, and should not to hide
+   changes in the "status" output to cause the users forget to commit
+   them.
+
+ * The mode to run tests with HTTP server tests disabled was broken.

+Git v2.0.2 Release Notes
+========================
+
+ * Documentation for "git submodule sync" forgot to say that the subcommand
+   can take the "--recursive" option.
+
+ * Mishandling of patterns in .gitignore that has trailing SPs quoted
+   with backslashes (e.g. ones that end with "\ ") have been
+   corrected.
+
+ * Recent updates to "git repack" started to duplicate objects that
+   are in packfiles marked with .keep flag into the new packfile by
+   mistake.
+
+ * "git clone -b brefs/tags/bar" would have mistakenly thought we were
+   following a single tag, even though it was a name of the branch,
+   because it incorrectly used strstr().
+
+ * "%G" (nothing after G) is an invalid pretty format specifier, but
+   the parser did not notice it as garbage.
+
+ * Code to avoid adding the same alternate object store twice was
+   subtly broken for a long time, but nobody seems to have noticed.
+
+ * A handful of code paths had to read the commit object more than
+   once when showing header fields that are usually not parsed.  The
+   internal data structure to keep track of the contents of the commit
+   object has been updated to reduce the need for this double-reading,
+   and to allow the caller find the length of the object.
+
+ * During "git rebase --merge", a conflicted patch could not be
+   skipped with "--skip" if the next one also conflicted.

+Git v2.0.5 Release Notes
+========================
+
+Fixes since v2.0.4
+------------------
+
+ * We used to allow committing a path ".Git/config" with Git that is
+   running on a case sensitive filesystem, but an attempt to check out
+   such a path with Git that runs on a case insensitive filesystem
+   would have clobbered ".git/config", which is definitely not what
+   the user would have expected.  Git now prevents you from tracking
+   a path with ".Git" (in any case combination) as a path component.
+
+ * On Windows, certain path components that are different from ".git"
+   are mapped to ".git", e.g. "git~1/config" is treated as if it were
+   ".git/config".  HFS+ has a similar issue, where certain unicode
+   codepoints are ignored, e.g. ".g\u200cit/config" is treated as if
+   it were ".git/config".  Pathnames with these potential issues are
+   rejected on the affected systems.  Git on systems that are not
+   affected by this issue (e.g. Linux) can also be configured to
+   reject them to ensure cross platform interoperability of the hosted
+   projects.
+
+ * "git fsck" notices a tree object that records such a path that can
+   be confused with ".git", and with receive.fsckObjects configuration
+   set to true, an attempt to "git push" such a tree object will be
+   rejected.  Such a path may not be a problem on a well behaving
+   filesystem but in order to protect those on HFS+ and on case
+   insensitive filesystems, this check is enabled on all platforms.
+
+A big "thanks!" for bringing this issue to us goes to our friends in
+the Mercurial land, namely, Matt Mackall and Augie Fackler.
+
+Also contains typofixes, documentation updates and trivial code clean-ups.

+Git v2.1 Release Notes
+======================
+
+Backward compatibility notes
+----------------------------
+
+ * The default value we give to the environment variable LESS has been
+   changed from "FRSX" to "FRX", losing "S" (chop long lines instead
+   of wrapping).  Existing users who prefer not to see line-wrapped
+   output may want to set
+
+     $ git config core.pager "less -S"
+
+   to restore the traditional behaviour.  It is expected that people
+   find output from most subcommands easier to read with the new
+   default, except for "blame" which tends to produce really long
+   lines.  To override the new default only for "git blame", you can
+   do this:
+
+     $ git config pager.blame "less -S"
+
+ * A few disused directories in contrib/ have been retired.
+
+
+Updates since v2.0
+------------------
+
+UI, Workflows & Features
+
+ * Since the very beginning of Git, we gave the LESS environment a
+   default value "FRSX" when we spawn "less" as the pager.  "S" (chop
+   long lines instead of wrapping) has been removed from this default
+   set of options, because it is more or less a personal taste thing,
+   as opposed to the others that have good justifications (i.e. "R" is
+   very much justified because many kinds of output we produce are
+   colored and "FX" is justified because output we produce is often
+   shorter than a page).
+
+ * The logic and data used to compute the display width needed for
+   UTF-8 strings have been updated to match Unicode 7.0 better.
+
+ * HTTP-based transports learned to better propagate the error messages from
+   the webserver to the client coming over the HTTP transport.
+
+ * The completion script for bash (in contrib/) has been updated to
+   better handle aliases that define a complex sequence of commands.
+
+ * The "core.preloadindex" configuration variable is enabled by default,
+   allowing modern platforms to take advantage of their
+   multiple cores.
+
+ * "git clone" applies the "if cloning from a local disk, physically
+   copy the repository using hardlinks, unless otherwise told not to with
+   --no-local" optimization when the url.*.insteadOf mechanism rewrites a
+   remote-repository "git clone $URL" into a
+   clone from a local disk.
+
+ * "git commit --date=<date>" option learned more
+   timestamp formats, including "--date=now".
+
+ * The `core.commentChar` configuration variable is used to specify a
+   custom comment character (other than the default "#") for
+   the commit message editor.  This can be set to `auto` to attempt to
+   choose a different character that does not conflict with any that
+   already starts a line in the message being edited, for cases like
+   "git commit --amend".
+
+ * "git format-patch" learned --signature-file=<file> to add the contents
+   of a file as a signature to the mail message it produces.
+
+ * "git grep" learned the grep.fullname configuration variable to force
+   "--full-name" to be the default.  This may cause regressions for
+   scripted users who do not expect this new behaviour.
+
+ * "git imap-send" learned to ask the credential helper for auth
+   material.
+
+ * "git log" and friends now understand the value "auto" for the
+   "log.decorate" configuration variable to enable the "--decorate"
+   option automatically when the output is sent to tty.
+
+ * "git merge" without an argument, even when there is an upstream
+   defined for the current branch, refused to run until
+   merge.defaultToUpstream is set to true.  Flip the default of that
+   configuration variable to true.
+
+ * "git mergetool" learned to drive the vimdiff3 backend.
+
+ * mergetool.prompt used to default to 'true', always asking "do you
+   really want to run the tool on this path?".  The default has been
+   changed to 'false'.  However, the prompt will still appear if
+   mergetool used its autodetection system to guess which tool to use.
+   Users who explicitly specify or configure a tool will no longer see
+   the prompt by default.
+
+   Strictly speaking, this is a backward incompatible change and
+   users need to explicitly set the variable to 'true' if they want
+   to be prompted to confirm running the tool on each path.
+
+ * "git replace" learned the "--edit" subcommand to create a
+   replacement by editing an existing object.
+
+ * "git replace" learned a "--graft" option to rewrite the parents of a
+   commit.
+
+ * "git send-email" learned "--to-cover" and "--cc-cover" options, to
+   tell it to copy To: and Cc: headers found in the first input file
+   when emitting later input files.
+
+ * "git svn" learned to cope with malformed timestamps with only one
+   digit in the hour part, e.g. 2014-01-07T5:01:02.048176Z, emitted
+   by some broken subversion server implementations.
+
+ * "git tag" when editing the tag message shows the name of the tag
+   being edited as a comment in the editor.
+
+ * "git tag" learned to pay attention to "tag.sort" configuration, to
+   be used as the default sort order when no --sort=<value> option
+   is given.
+
+ * A new "git verify-commit" command, to check GPG signatures in signed
+   commits, in a way similar to "git verify-tag" is used to check
+   signed tags, was added.
+
+
+Performance, Internal Implementation, etc.
+
+ * Build procedure for 'subtree' (in contrib/) has been cleaned up.
+
+ * Support for the profile-feedback build, which has
+   bit-rotted for quite a while, has been updated.
+
+ * An experimental format to use two files (the base file and
+   incremental changes relative to it) to represent the index has been
+   introduced; this may reduce I/O cost of rewriting a large index
+   when only small part of the working tree changes.
+
+ * Effort to shrink the size of patches Windows folks maintain on top
+   by upstreaming them continues.  More tests that are not applicable
+   to the Windows environment are identified and either skipped or
+   made more portable.
+
+ * Eradication of "test $condition -a $condition" from our scripts
+   continues.
+
+ * The `core.deltabasecachelimit` used to default to 16 MiB , but this
+   proved to be too small, and has been bumped to 96 MiB.
+
+ * "git blame" has been optimized greatly by reorganising the data
+   structure that is used to keep track of the work to be done.
+
+ * "git diff" that compares 3-or-more trees (e.g. parents and the
+   result of a merge) has been optimized.
+
+ * The API to update/delete references are being converted to handle
+   updates to multiple references in a transactional way.  As an
+   example, "update-ref --stdin [-z]" has been updated to use this
+   API.
+
+ * skip_prefix() and strip_suffix() API functions are used a lot more
+   widely throughout the codebase now.
+
+ * Parts of the test scripts can be skipped by using a range notation,
+   e.g. "sh t1234-test.sh --run='1-4 6 8-'" to omit test piece 5 and 7
+   and run everything else.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.0
+----------------
+
+Unless otherwise noted, all the fixes since v2.0 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * We used to unconditionally disable the pager in the pager process
+   we spawn to feed out output, but that prevented people who want to
+   run "less" within "less" from doing so.
+   (merge c0459ca je/pager-do-not-recurse later to maint).
+
+ * Tools that read diagnostic output in our standard error stream do
+   not want to see terminal control sequence (e.g. erase-to-eol).
+   Detect them by checking if the standard error stream is connected
+   to a tty.
+   (merge 38de156 mn/sideband-no-ansi later to maint).
+
+ * Mishandling of patterns in .gitignore that have trailing SPs quoted
+   with backslashes (e.g. ones that end with "\ ") has been
+   corrected.
+   (merge 97c1364be6b pb/trim-trailing-spaces later to maint).
+
+ * Reworded the error message given upon a failure to open an existing
+   loose object file due to e.g. permission issues; it was reported as
+   the object being corrupt, but that is not quite true.
+   (merge d6c8a05 jk/report-fail-to-read-objects-better later to maint).
+
+ * "git log -2master" is a common typo that shows two commits starting
+   from whichever random branch that is not 'master' that happens to
+   be checked out currently.
+   (merge e3fa568 jc/revision-dash-count-parsing later to maint).
+
+ * Code to avoid adding the same alternate object store twice was
+   subtly broken for a long time, but nobody seems to have noticed.
+   (merge 80b4785 rs/fix-alt-odb-path-comparison later to maint).
+   (merge 539e750 ek/alt-odb-entry-fix later to maint).
+
+ * The "%<(10,trunc)%s" pretty format specifier in the log family of
+   commands is used to truncate the string to a given length (e.g. 10
+   in the example) with padding to column-align the output, but did
+   not take into account that number of bytes and number of display
+   columns are different.
+   (merge 7d50987 as/pretty-truncate later to maint).
+
+ * "%G" (nothing after G) is an invalid pretty format specifier, but
+   the parser did not notice it as garbage.
+   (merge 958b2eb jk/pretty-G-format-fixes later to maint).
+
+ * A handful of code paths had to read the commit object more than
+   once when showing header fields that are usually not parsed.  The
+   internal data structure to keep track of the contents of the commit
+   object has been updated to reduce the need for this double-reading,
+   and to allow the caller find the length of the object.
+   (merge 218aa3a jk/commit-buffer-length later to maint).
+
+ * The "mailmap.file" configuration option did not support tilde
+   expansion (i.e. ~user/path and ~/path).
+   (merge 9352fd5 ow/config-mailmap-pathname later to maint).
+
+ * The completion scripts (in contrib/) did not know about quite a few
+   options that are common between "git merge" and "git pull", and a
+   couple of options unique to "git merge".
+   (merge 8fee872 jk/complete-merge-pull later to maint).
+
+ * The unix-domain socket used by the sample credential cache daemon
+   tried to unlink an existing stale one at a wrong path, if the path
+   to the socket was given as an overlong path that does not fit in
+   the sun_path member of the sockaddr_un structure.
+   (merge 2869b3e rs/fix-unlink-unix-socket later to maint).
+
+ * An ancient rewrite passed a wrong pointer to a curl library
+   function in a rarely used code path.
+   (merge 479eaa8 ah/fix-http-push later to maint).
+
+ * "--ignore-space-change" option of "git apply" ignored the spaces
+   at the beginning of lines too aggressively, which is inconsistent
+   with the option of the same name that "diff" and "git diff" have.
+   (merge 14d3bb4 jc/apply-ignore-whitespace later to maint).
+
+ * "git blame" miscounted the number of columns needed to show localized
+   timestamps, resulting in a jaggy left-side-edge for the source code
+   lines in its output.
+   (merge dd75553 jx/blame-align-relative-time later to maint).
+
+ * "git blame" assigned the blame to the copy in the working-tree if
+   the repository is set to core.autocrlf=input and the file used CRLF
+   line endings.
+   (merge 4d4813a bc/blame-crlf-test later to maint).
+
+ * "git clone -b brefs/tags/bar" would have mistakenly thought we were
+   following a single tag, even though it was a name of the branch,
+   because it incorrectly used strstr().
+   (merge 60a5f5f jc/fix-clone-single-starting-at-a-tag later to maint).
+
+ * "git commit --allow-empty-message -C $commit" did not work when the
+   commit did not have any log message.
+   (merge 076cbd6 jk/commit-C-pick-empty later to maint).
+
+ * "git diff --find-copies-harder" sometimes pretended as if the mode
+   bits have changed for paths that are marked with the assume-unchanged
+   bit.
+   (merge 5304810 jk/diff-files-assume-unchanged later to maint).
+
+ * "filter-branch" left an empty single-parent commit that results when
+   all parents of a merge commit get mapped to the same commit, even
+   under "--prune-empty".
+   (merge 79bc4ef cb/filter-branch-prune-empty-degenerate-merges later to maint).
+
+ * "git format-patch" did not enforce the rule that the "--follow"
+   option from the log/diff family of commands must be used with
+   exactly one pathspec.
+   (merge dd63f16 jk/diff-follow-must-take-one-pathspec later to maint).
+
+ * "git gc --auto" was recently changed to run in the background to
+   give control back early to the end-user sitting in front of the
+   terminal, but it forgot that housekeeping involving reflogs should
+   be done without other processes competing for accesses to the refs.
+   (merge 62aad18 nd/daemonize-gc later to maint).
+
+ * "git grep -O" to show the lines that hit in the pager did not work
+   well with case insensitive search.  We now spawn "less" with its
+   "-I" option when it is used as the pager (which is the default).
+   (merge f7febbe sk/spawn-less-case-insensitively-from-grep-O-i later to maint).
+
+ * We used to disable threaded "git index-pack" on platforms without
+   thread-safe pread(); use a different workaround for such
+   platforms to allow threaded "git index-pack".
+   (merge 3953949 nd/index-pack-one-fd-per-thread later to maint).
+
+ * The error reporting from "git index-pack" has been improved to
+   distinguish missing objects from type errors.
+   (merge 77583e7 jk/index-pack-report-missing later to maint).
+
+ * "log --show-signature" incorrectly decided the color to paint a
+   mergetag that was and was not correctly validated.
+   (merge 42c55ce mg/fix-log-mergetag-color later to maint).
+
+ * "log --show-signature" did not pay attention to the "--graph" option.
+   (merge cf3983d zk/log-graph-showsig later to maint).
+
+ * "git mailinfo" used to read beyond the ends of header strings while
+   parsing an incoming e-mail message to extract the patch.
+   (merge b1a013d rs/mailinfo-header-cmp later to maint).
+
+ * On a case insensitive filesystem, merge-recursive incorrectly
+   deleted the file that is to be renamed to a name that is the same
+   except for case differences.
+   (merge baa37bf dt/merge-recursive-case-insensitive later to maint).
+
+ * Merging changes into a file that ends in an incomplete line made the
+   last line into a complete one, even when the other branch did not
+   change anything around the end of file.
+   (merge ba31180 mk/merge-incomplete-files later to maint).
+
+ * "git pack-objects" unnecessarily copied the previous contents when
+   extending the hashtable, even though it will populate the table
+   from scratch anyway.
+   (merge fb79947 rs/pack-objects-no-unnecessary-realloc later to maint).
+
+ * Recent updates to "git repack" started to duplicate objects that
+   are in packfiles marked with the .keep flag into the new packfile by
+   mistake.
+   (merge d078d85 jk/repack-pack-keep-objects later to maint).
+
+ * "git rerere forget" did not work well when merge.conflictstyle
+   was set to a non-default value.
+   (merge de3d8bb fc/rerere-conflict-style later to maint).
+
+ * "git remote rm" and "git remote prune" can involve removing many
+   refs at once, which is not a very efficient thing to do when very
+   many refs exist in the packed-refs file.
+   (merge e6bea66 jl/remote-rm-prune later to maint).
+
+ * "git log --exclude=<glob> --all | git shortlog" worked as expected,
+   but "git shortlog --exclude=<glob> --all", which is supposed to be
+   identical to the above pipeline, was not accepted at the command
+   line argument parser level.
+   (merge eb07774 jc/shortlog-ref-exclude later to maint).
+
+ * The autostash mode of "git rebase -i" did not restore the dirty
+   working tree state if the user aborted the interactive rebase by
+   emptying the insn sheet.
+   (merge ddb5432 rr/rebase-autostash-fix later to maint).
+
+ * "git rebase --fork-point" did not filter out patch-identical
+   commits correctly.
+
+ * During "git rebase --merge", a conflicted patch could not be
+   skipped with "--skip" if the next one also conflicted.
+   (merge 95104c7 bc/fix-rebase-merge-skip later to maint).
+
+ * "git show -s" (i.e. show log message only) used to incorrectly emit
+   an extra blank line after a merge commit.
+   (merge ad2f725 mk/show-s-no-extra-blank-line-for-merges later to maint).
+
+ * "git status", even though it is a read-only operation, tries to
+   update the index with refreshed lstat(2) info to optimize future
+   accesses to the working tree opportunistically, but this could
+   race with a "read-write" operation that modifies the index while it
+   is running.  Detect such a race and avoid overwriting the index.
+   (merge 426ddee ym/fix-opportunistic-index-update-race later to maint).
+
+ * "git status" (and "git commit") behaved as if changes in a modified
+   submodule are not there if submodule.*.ignore configuration is set,
+   which was misleading.  The configuration is only to unclutter diff
+   output during the course of development, and not to hide
+   changes in the "status" output to cause the users forget to commit
+   them.
+   (merge c215d3d jl/status-added-submodule-is-never-ignored later to maint).
+
+ * Documentation for "git submodule sync" forgot to say that the subcommand
+   can take the "--recursive" option.
+   (merge 9393ae7 mc/doc-submodule-sync-recurse later to maint).
+
+ * "git update-index --cacheinfo" in 2.0 release crashed on a
+   malformed command line.
+   (merge c8e1ee4 jc/rev-parse-argh-dashed-multi-words later to maint).
+
+ * The mode to run tests with HTTP server tests disabled was broken.
+   (merge afa53fe na/no-http-test-in-the-middle later to maint).

+Git v2.1.1 Release Notes
+========================
+
+ * Git 2.0 had a regression where "git fetch" into a shallowly
+   cloned repository from a repository with bitmap object index
+   enabled did not work correctly.  This has been corrected.
+
+ * Git 2.0 had a regression which broke (rarely used) "git diff-tree
+   -t".  This has been corrected.
+
+ * "git log --pretty/format=" with an empty format string did not
+   mean the more obvious "No output whatsoever" but "Use default
+   format", which was counterintuitive.  Now it means "nothing shown
+   for the log message part".
+
+ * "git -c section.var command" and "git -c section.var= command"
+   should pass the configuration differently (the former should be a
+   boolean true, the latter should be an empty string), but they
+   didn't work that way.  Now it does.
+
+ * Applying a patch not generated by Git in a subdirectory used to
+   check the whitespace breakage using the attributes for incorrect
+   paths. Also whitespace checks were performed even for paths
+   excluded via "git apply --exclude=<path>" mechanism.
+
+ * "git bundle create" with date-range specification were meant to
+   exclude tags outside the range, but it did not work correctly.
+
+ * "git add x" where x that used to be a directory has become a
+   symbolic link to a directory misbehaved.
+
+ * The prompt script checked $GIT_DIR/ref/stash file to see if there
+   is a stash, which was a no-no.
+
+ * "git checkout -m" did not switch to another branch while carrying
+   the local changes forward when a path was deleted from the index.
+
+ * With sufficiently long refnames, fast-import could have overflown
+   an on-stack buffer.
+
+ * After "pack-refs --prune" packed refs at the top-level, it failed
+   to prune them.
+
+ * "git gc --auto" triggered from "git fetch --quiet" was not quiet.

+Git v2.1.2 Release Notes
+========================
+
+ * "git push" over HTTP transport had an artificial limit on number of
+   refs that can be pushed imposed by the command line length.
+
+ * When receiving an invalid pack stream that records the same object
+   twice, multiple threads got confused due to a race.
+
+ * An attempt to remove the entire tree in the "git fast-import" input
+   stream caused it to misbehave.
+
+ * Reachability check (used in "git prune" and friends) did not add a
+   detached HEAD as a starting point to traverse objects still in use.
+
+ * "git config --add section.var val" used to lose existing
+   section.var whose value was an empty string.
+
+ * "git fsck" failed to report that it found corrupt objects via its
+   exit status in some cases.

+Git v2.1.3 Release Notes
+========================
+
+ * Some MUAs mangled a line in a message that begins with "From " to
+   ">From " when writing to a mailbox file and feeding such an input to
+   "git am" used to lose such a line.
+
+ * "git daemon" (with NO_IPV6 build configuration) used to incorrectly

+   hostname is not found.
+
+ * Newer versions of 'meld' breaks the auto-detection we use to see if

+
+ * "git pack-objects" forgot to disable the codepath to generate

+   pack.
+
+ * "gitweb" used deprecated CGI::startfrom, which was removed from
+   CGI.pm as of 4.04; use CGI::start_from instead.
+
+ * "git log" documentation had an example section marked up not
+   quite correctly, which passed AsciiDoc but failed with
+   AsciiDoctor.
+
+Also contains some documentation updates.

+Git v2.1.4 Release Notes
+========================
+
+Fixes since v2.1.3
+------------------
+
+ * We used to allow committing a path ".Git/config" with Git that is
+   running on a case sensitive filesystem, but an attempt to check out
+   such a path with Git that runs on a case insensitive filesystem
+   would have clobbered ".git/config", which is definitely not what
+   the user would have expected.  Git now prevents you from tracking
+   a path with ".Git" (in any case combination) as a path component.
+
+ * On Windows, certain path components that are different from ".git"
+   are mapped to ".git", e.g. "git~1/config" is treated as if it were
+   ".git/config".  HFS+ has a similar issue, where certain unicode
+   codepoints are ignored, e.g. ".g\u200cit/config" is treated as if
+   it were ".git/config".  Pathnames with these potential issues are
+   rejected on the affected systems.  Git on systems that are not
+   affected by this issue (e.g. Linux) can also be configured to
+   reject them to ensure cross platform interoperability of the hosted
+   projects.
+
+ * "git fsck" notices a tree object that records such a path that can
+   be confused with ".git", and with receive.fsckObjects configuration
+   set to true, an attempt to "git push" such a tree object will be
+   rejected.  Such a path may not be a problem on a well behaving
+   filesystem but in order to protect those on HFS+ and on case
+   insensitive filesystems, this check is enabled on all platforms.
+
+A big "thanks!" for bringing this issue to us goes to our friends in
+the Mercurial land, namely, Matt Mackall and Augie Fackler.
+
+Also contains typofixes, documentation updates and trivial code clean-ups.

+Git v2.2 Release Notes
+======================
+
+Updates since v2.1
+------------------
+
+Ports
+
+ * Building on older MacOS X systems automatically sets
+   the necessary NO_APPLE_COMMON_CRYPTO build-time option.
+
+ * Building with NO_PTHREADS has been resurrected.
+
+ * Compilation options have been updated a bit to better support the
+   z/OS port.
+
+
+UI, Workflows & Features
+
+ * "git archive" learned to filter what gets archived with a pathspec.
+
+ * "git config --edit --global" starts from a skeletal per-user
+   configuration file contents, instead of a total blank, when the
+   user does not already have any global config.  This immediately
+   reduces the need to later ask "Have you forgotten to set
+   core.user?", and we can add more to the template as we gain
+   more experience.
+
+ * "git stash list -p" used to be almost always a no-op because each
+   stash entry is represented as a merge commit.  It learned to show
+   the difference between the base commit version and the working tree
+   version, which is in line with what "git stash show" gives.
+
+ * Sometimes users want to report a bug they experience on their
+   repository, but they are not at liberty to share the contents of
+   the repository.  "fast-export" was taught an "--anonymize" option
+   to replace blob contents, names of people, paths and log
+   messages with bland and simple strings to help them.
+
+ * "git difftool" learned an option to stop feeding paths to the
+   diff backend when it exits with a non-zero status.
+
+ * "git grep" learned to paint (or not paint) partial matches on
+   context lines when showing "grep -C<num>" output in color.
+
+ * "log --date=iso" uses a slight variant of the ISO 8601 format that is
+   more human readable.  A new "--date=iso-strict" option gives
+   datetime output that conforms more strictly.
+
+ * The logic "git prune" uses is more resilient against various corner
+   cases.
+
+ * A broken reimplementation of Git could write an invalid index that
+   records both stage #0 and higher-stage entries for the same path.
+   We now notice and reject such an index, as there is no sensible
+   fallback (we do not know if the broken tool wanted to resolve and
+   forgot to remove the higher-stage entries, or if it wanted to unresolve
+   and forgot to remove the stage #0 entry).
+
+ * The temporary files "git mergetool" uses are renamed to avoid too
+   many dots in them (e.g. a temporary file for "hello.c" used to be
+   named e.g. "hello.BASE.4321.c" but now uses underscore instead,
+   e.g. "hello_BASE_4321.c", to allow us to have multiple variants).
+
+ * The temporary files "git mergetool" uses can be placed in a newly
+   created temporary directory, instead of the current directory, by
+   setting the mergetool.writeToTemp configuration variable.
+
+ * "git mergetool" understands "--tool bc" now, as version 4 of
+   BeyondCompare can be driven the same way as its version 3 and it
+   feels awkward to say "--tool bc3" to run version 4.
+
+ * The "pre-receive" and "post-receive" hooks are no longer required
+   to consume their input fully (not following this requirement used
+   to result in intermittent errors in "git push").
+
+ * The pretty-format specifier "%d", which expands to " (tagname)"
+   for a tagged commit, gained a cousin "%D" that just gives the
+   "tagname" without frills.
+
+ * "git push" learned "--signed" push, that allows a push (i.e.
+   request to update the refs on the other side to point at a new
+   history, together with the transmission of necessary objects) to be
+   signed, so that it can be verified and audited, using the GPG
+   signature of the person who pushed, that the tips of branches at a
+   public repository really point the commits the pusher wanted to,
+   without having to "trust" the server.
+
+ * "git interpret-trailers" is a new filter to programmatically edit
+   the tail end of the commit log messages, e.g. "Signed-off-by:".
+
+ * "git help everyday" shows the "Everyday Git in 20 commands or so"
+   document, whose contents have been updated to match more modern
+   Git practice.
+
+ * On the "git svn" front, work progresses to reduce memory consumption and
+   to improve handling of mergeinfo.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * The API to manipulate the "refs" has been restructured to make it
+   more transactional, with the eventual goal to allow all-or-none
+   atomic updates and migrating the storage to something other than
+   the traditional filesystem based one (e.g. databases).
+
+ * The lockfile API and its users have been cleaned up.
+
+ * We no longer attempt to keep track of individual dependencies to
+   the header files in the build procedure, relying instead on automated
+   dependency generation support from modern compilers.
+
+ * In tests, we have been using NOT_{MINGW,CYGWIN} test prerequisites
+   long before negated prerequisites e.g. !MINGW were invented.
+   The former has been converted to the latter to avoid confusion.
+
+ * Optimized looking up a remote's configuration in a repository with very many
+   remotes defined.
+
+ * There are cases where you lock and open to write a file, close it
+   to show the updated contents to an external processes, and then have
+   to update the file again while still holding the lock; now the
+   lockfile API has support for such an access pattern.
+
+ * The API to allocate the structure to keep track of commit
+   decoration has been updated to make it less cumbersome to use.
+
+ * An in-core caching layer to let us avoid reading the same
+   configuration files several times has been added.  A few commands
+   have been converted to use this subsystem.
+
+ * Various code paths have been cleaned up and simplified by using
+   the "strbuf", "starts_with()", and "skip_prefix()" APIs more.
+
+ * A few codepaths that died when large blobs that would not fit in
+   core are involved in their operation have been taught to punt
+   instead, by e.g. marking a too-large blob as not to be diffed.
+
+ * A few more code paths in "commit" and "checkout" have been taught
+   to repopulate the cache-tree in the index, to help speed up later
+   "write-tree" (used in "commit") and "diff-index --cached" (used in
+   "status").
+
+ * A common programming mistake to assign the same short option name
+   to two separate options is detected by the parse_options() API to help
+   developers.
+
+ * The code path to write out the packed-refs file has been optimized,
+   which especially matters in a repository with a large number of
+   refs.
+
+ * The check to see if a ref $F can be created by making sure no
+   existing ref has $F/ as its prefix has been optimized, which
+   especially matters in a repository with a large number of existing
+   refs.
+
+ * "git fsck" was taught to check the contents of tag objects a bit more.
+
+ * "git hash-object" was taught a "--literally" option to help
+   debugging.
+
+ * When running a required clean filter, we do not have to mmap the
+   original before feeding the filter.  Instead, stream the file
+   contents directly to the filter and process its output.
+
+ * The scripts in the test suite can be run with the "-x" option to show
+   a shell-trace of each command they run.
+
+ * The "run-command" API learned to manage the argv and environment
+   arrays for child process, alleviating the need for the callers to
+   allocate and deallocate them.
+
+ * Some people use AsciiDoctor, instead of AsciiDoc, to format our
+   documentation set; the documentation has been adjusted to be usable
+   by both, as AsciiDoctor is pickier than AsciiDoc about its input
+   mark-up.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.1
+----------------
+
+Unless otherwise noted, all the fixes since v2.1 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * "git log --pretty/format=" with an empty format string did not
+   mean the more obvious "No output whatsoever" but "Use default
+   format", which was counterintuitive.
+
+ * "git -c section.var command" and "git -c section.var= command"
+   should pass the configuration value differently (the former should be a
+   boolean true, the latter should be an empty string).
+
+ * Applying a patch not generated by Git in a subdirectory used to
+   check for whitespace breakage using the attributes of incorrect
+   paths. Also whitespace checks were performed even for paths
+   excluded via the "git apply --exclude=<path>" mechanism.
+
+ * "git bundle create" with a date-range specification was meant to
+   exclude tags outside the range, but it didn't.
+
+ * "git add x" where x used to be a directory and is now a
+   symbolic link to a directory misbehaved.
+
+ * The prompt script checked the $GIT_DIR/ref/stash file to see if there
+   is a stash, which was a no-no.
+
+ * Pack-protocol documentation had a minor typo.
+
+ * "git checkout -m" did not switch to another branch while carrying
+   the local changes forward when a path was deleted from the index.
+
+ * "git daemon" (with NO_IPV6 build configuration) used to incorrectly
+   use the hostname even when gethostbyname() reported that the given
+   hostname is not found.
+   (merge 107efbe rs/daemon-fixes later to maint).
+
+ * With sufficiently long refnames, "git fast-import" could have
+   overflowed an on-stack buffer.
+
+ * After "pack-refs --prune" packed refs at the top-level, it failed
+   to prune them.
+
+ * Progress output from "git gc --auto" was visible in "git fetch -q".
+
+ * We used to pass -1000 to poll(2), expecting it to also mean "no
+   timeout", which should be spelled as -1.
+
+ * "git rebase" documentation was unclear that it is required to
+   specify on what <upstream> the rebase is to be done when telling it
+   to first check out <branch>.
+   (merge 95c6826 so/rebase-doc later to maint).
+
+ * "git push" over HTTP transport had an artificial limit on the number of
+   refs that can be pushed, imposed by the command line length.
+   (merge 26be19b jk/send-pack-many-refspecs later to maint).
+
+ * When receiving an invalid pack stream that records the same object
+   twice, multiple threads got confused due to a race.
+   (merge ab791dd jk/index-pack-threading-races later to maint).
+
+ * An attempt to remove the entire tree in the "git fast-import" input
+   stream caused it to misbehave.
+   (merge 2668d69 mb/fast-import-delete-root later to maint).
+
+ * Reachability check (used in "git prune" and friends) did not add a
+   detached HEAD as a starting point to traverse objects still in use.
+   (merge c40fdd0 mk/reachable-protect-detached-head later to maint).
+
+ * "git config --add section.var val" when section.var already has an
+   empty-string value used to lose the empty-string value.
+   (merge c1063be ta/config-add-to-empty-or-true-fix later to maint).
+
+ * "git fsck" failed to report that it found corrupt objects via its
+   exit status in some cases.
+   (merge 30d1038 jk/fsck-exit-code-fix later to maint).
+
+ * Use of the "--verbose" option used to break "git branch --merged".
+   (merge 12994dd jk/maint-branch-verbose-merged later to maint).
+
+ * Some MUAs mangle a line in a message that begins with "From " to
+   ">From " when writing to a mailbox file, and feeding such an input
+   to "git am" used to lose such a line.
+   (merge 85de86a jk/mbox-from-line later to maint).
+
+ * "rev-parse --verify --quiet $name" is meant to quietly exit with a
+   non-zero status when $name is not a valid object name, but still
+   gave error messages in some cases.
+
+ * A handful of C source files have been updated to include
+   "git-compat-util.h" as the first thing, to conform better to our
+   coding guidelines.
+   (merge 1c4b660 da/include-compat-util-first-in-c later to maint).
+
+ * The t7004 test, which tried to run Git with small stack space, has been
+   updated to use a bit larger stack to avoid false breakage on some
+   platforms.
+   (merge b9a1907 sk/tag-contains-wo-recursion later to maint).
+
+ * A few documentation pages had example sections marked up not quite
+   correctly, which passed AsciiDoc but failed with AsciiDoctor.
+   (merge c30c43c bc/asciidoc-pretty-formats-fix later to maint).
+   (merge f8a48af bc/asciidoc later to maint).
+
+ * "gitweb" used deprecated CGI::startfrom, which was removed from
+   CGI.pm as of 4.04; use CGI::start_from instead.
+   (merge 4750f4b rm/gitweb-start-form later to maint).
+
+ * Newer versions of 'meld' break the auto-detection we use to see if
+   they are new enough to support the `--output` option.
+   (merge b12d045 da/mergetool-meld later to maint).
+
+ * "git pack-objects" forgot to disable the codepath to generate the
+   object reachability bitmap when it needs to split the resulting
+   pack.
+   (merge 2113471 jk/pack-objects-no-bitmap-when-splitting later to maint).
+
+ * The code to use cache-tree trusted the on-disk data too much and
+   fell into an infinite loop upon seeing an incorrectly recorded
+   index file.
+   (merge 729dbbd jk/cache-tree-protect-from-broken-libgit2 later to maint).
+
+ * "git fetch" into a repository where branch B was deleted earlier,
+   back when it had reflog enabled, and then branch B/C is fetched
+   into it without reflog enabled, which is arguably an unlikely
+   corner case, unnecessarily failed.
+   (merge aae828b jk/fetch-reflog-df-conflict later to maint).
+
+ * "git log --first-parent -L..." used to crash.
+   (merge a8787c5 tm/line-log-first-parent later to maint).

+Git v2.2.1 Release Notes
+========================
+
+Fixes since v2.2
+----------------
+
+ * We used to allow committing a path ".Git/config" with Git that is
+   running on a case sensitive filesystem, but an attempt to check out
+   such a path with Git that runs on a case insensitive filesystem
+   would have clobbered ".git/config", which is definitely not what
+   the user would have expected.  Git now prevents you from tracking
+   a path with ".Git" (in any case combination) as a path component.
+
+ * On Windows, certain path components that are different from ".git"
+   are mapped to ".git", e.g. "git~1/config" is treated as if it were
+   ".git/config".  HFS+ has a similar issue, where certain unicode
+   codepoints are ignored, e.g. ".g\u200cit/config" is treated as if
+   it were ".git/config".  Pathnames with these potential issues are
+   rejected on the affected systems.  Git on systems that are not
+   affected by this issue (e.g. Linux) can also be configured to
+   reject them to ensure cross platform interoperability of the hosted
+   projects.
+
+ * "git fsck" notices a tree object that records such a path that can
+   be confused with ".git", and with receive.fsckObjects configuration
+   set to true, an attempt to "git push" such a tree object will be
+   rejected.  Such a path may not be a problem on a well behaving
+   filesystem but in order to protect those on HFS+ and on case
+   insensitive filesystems, this check is enabled on all platforms.
+
+A big "thanks!" for bringing this issue to us goes to our friends in
+the Mercurial land, namely, Matt Mackall and Augie Fackler.
+
+Also contains typofixes, documentation updates and trivial code clean-ups.

+Git v2.2.2 Release Notes
+========================
+
+Fixes since v2.2.1
+------------------
+
+ * "git checkout $treeish $path", when $path in the index and the
+   working tree already matched what is in $treeish at the $path,
+   still overwrote the $path unnecessarily.
+
+ * "git config --get-color" did not parse its command line arguments
+   carefully.
+
+ * open() emulated on Windows platforms did not give EISDIR upon
+   an attempt to open a directory for writing.
+
+ * A few code paths used abs() when they should have used labs() on
+   long integers.
+
+ * "gitweb" used to depend on a behaviour recent CGI.pm deprecated.
+
+ * "git init" (hence "git clone") initialized the per-repository
+   configuration file .git/config with x-bit by mistake.
+
+ * Git 2.0 was supposed to make the "simple" mode for the default of
+   "git push", but it didn't.
+
+ * "Everyday" document had a broken link.
+
+ * The build procedure did not bother fixing perl and python scripts
+   when NO_PERL and NO_PYTHON build-time configuration changed.
+
+ * The code that reads the reflog from the newer to the older entries
+   did not handle an entry that crosses a boundary of block it uses to
+   read them correctly.
+
+ * "git apply" was described in the documentation to take --ignore-date
+   option, which it does not.
+
+ * Traditionally we tried to avoid interpreting date strings given by
+   the user as future dates, e.g. GIT_COMMITTER_DATE=2014-12-10 when
+   used early November 2014 was taken as "October 12, 2014" because it
+   is likely that a date in the future, December 10, is a mistake.
+   This heuristics has been loosened to allow people to express future
+   dates (most notably, --until=<date> may want to be far in the
+   future) and we no longer tiebreak by future-ness of the date when
+
+    (1) ISO-like format is used, and
+    (2) the string can make sense interpreted as both y-m-d and y-d-m.
+
+   Git may still have to use the heuristics to tiebreak between dd/mm/yy
+   and mm/dd/yy, though.
+
+ * The code to abbreviate an object name to its short unique prefix
+   has been optimized when no abbreviation was requested.
+
+ * "git add --ignore-errors ..." did not ignore an error to
+   give a file that did not exist.
+
+ * Git did not correctly read an overlong refname from a packed refs
+   file.
+
+Also contains typofixes, documentation updates and trivial code clean-ups.

+Git v2.3 Release Notes
+======================
+
+This one ended up to be a release with lots of small corrections and
+improvements without big uncomfortably exciting features.  The recent
+security fix that went to 2.2.1 and older maintenance tracks is also
+contained in this update.
+
+
+Updates since v2.2
+------------------
+
+Ports
+
+ * Recent gcc toolchain on Cygwin started throwing compilation warning,
+   which has been squelched.
+
+ * A few updates to build on platforms that lack tv_nsec,
+   clock_gettime, CLOCK_MONOTONIC and HMAC_CTX_cleanup (e.g. older
+   RHEL) have been added.
+
+
+UI, Workflows & Features
+
+ * It was cumbersome to use "GIT_SSH" mechanism when the user wanted
+   to pass an extra set of arguments to the underlying ssh.  A new
+   environment variable GIT_SSH_COMMAND can be used for this.
+
+ * A request to store an empty note via "git notes" meant to remove
+   note from the object but with --allow-empty we will store a
+   (surprise!)  note that is empty.
+
+ * "git interpret-trailers" learned to properly handle the
+   "Conflicts:" block at the end.
+
+ * "git am" learned "--message-id" option to copy the message ID of
+   the incoming e-mail to the log message of resulting commit.
+
+ * "git clone --reference=<over there>" learned the "--dissociate"
+   option to go with it; it borrows objects from the reference object
+   store while cloning only to reduce network traffic and then
+   dissociates the resulting clone from the reference by performing
+   local copies of borrowed objects.
+
+ * "git send-email" learned "--transfer-encoding" option to force a
+   non-fault Content-Transfer-Encoding header (e.g. base64).
+
+ * "git send-email" normally identifies itself via X-Mailer: header in
+   the message it sends out.  A new command line flag --no-xmailer
+   allows the user to squelch the header.
+
+ * "git push" into a repository with a working tree normally refuses
+   to modify the branch that is checked out.  The command learned to
+   optionally do an equivalent of "git reset --hard" only when there
+   is no change to the working tree and the index instead, which would
+   be useful to "deploy" by pushing into a repository.
+
+ * "git new-workdir" (in contrib/) can be used to populate an empty
+   and existing directory now.
+
+ * Credential helpers are asked in turn until one of them give
+   positive response, which is cumbersome to turn off when you need to
+   run Git in an automated setting.  The credential helper interface
+   learned to allow a helper to say "stop, don't ask other helpers."
+   Also GIT_TERMINAL_PROMPT environment can be set to false to disable
+   our built-in prompt mechanism for passwords.
+
+ * "git branch -d" (delete) and "git branch -m" (move) learned to
+   honor "-f" (force) flag; unlike many other subcommands, the way to
+   force these have been with separate "-D/-M" options, which was
+   inconsistent.
+
+ * "diff-highlight" filter (in contrib/) allows its color output to be
+   customized via configuration variables.
+
+ * "git imap-send" learned to take "-v" (verbose) and "-q" (quiet)
+   command line options.
+
+ * "git remote add $name $URL" is now allowed when "url.$URL.insteadOf"
+   is already defined.
+
+ * "git imap-send" now can be built to use cURL library to talk to
+   IMAP servers (if the library is recent enough, of course).
+   This allows you to use authenticate method other than CRAM-MD5,
+   among other things.
+
+ * "git imap-send" now allows GIT_CURL_VERBOSE environment variable to
+   control the verbosity when talking via the cURL library.
+
+ * The prompt script (in contrib/) learned to optionally hide prompt
+   when in an ignored directory by setting GIT_PS1_HIDE_IF_PWD_IGNORED
+   shell variable.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * Earlier we made "rev-list --object-edge" more aggressively list the
+   objects at the edge commits, in order to reduce number of objects　
+   fetched into a shallow repository, but the change affected cases
+   other than "fetching into a shallow repository" and made it
+   unusably slow (e.g. fetching into a normal repository should not
+   have to suffer the overhead from extra processing).  Limit it to a
+   more specific case by introducing --objects-edge-aggressive, a new
+   option to rev-list.
+
+ * Squelched useless compiler warnings on Mac OS X regarding the
+   crypto API.
+
+ * The procedure to generate unicode table has been simplified.
+
+ * Some filesystems assign filemodes in a strange way, fooling then
+   automatic "filemode trustability" check done during a new
+   repository creation.  The initialization codepath has been hardened
+   against this issue.
+
+ * The codepath in "git remote update --prune" to drop many refs has
+   been optimized.
+
+ * The API into get_merge_bases*() family of functions was easy to
+   misuse, which has been corrected to make it harder to do so.
+
+ * Long overdue departure from the assumption that S_IFMT is shared by
+   everybody made in 2005, which was necessary to port to z/OS.
+
+ * "git push" and "git fetch" did not communicate an overlong refname
+   correctly.  Now it uses 64kB sideband to accommodate longer ones.
+
+ * Recent GPG changes the keyring format and drops support for RFC1991
+   formatted signatures, breaking our existing tests.
+
+ * "git-prompt" (in contrib/) used a variable from the global scope,
+   possibly contaminating end-user's namespace.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.2
+----------------
+
+Unless otherwise noted, all the fixes since v2.2 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * "git http-push" over WebDAV (aka dumb http-push) was broken in
+   v2.2.2 when parsing a symbolic ref, resulting in a bogus request
+   that gets rejected by recent versions of cURL library.
+   (merge f6786c8 jk/http-push-symref-fix later to maint).
+
+ * The logic in "git bisect bad HEAD" etc. to avoid forcing the test
+   of the common ancestor of bad and good commits was broken.
+   (merge 07913d5 cc/bisect-rev-parsing later to maint).
+
+ * "git checkout-index --temp=$target $path" did not work correctly
+   for paths outside the current subdirectory in the project.
+   (merge 74c4de5 es/checkout-index-temp later to maint).
+
+ * The report from "git checkout" on a branch that builds on another
+   local branch by setting its branch.*.merge to branch name (not a
+   full refname) incorrectly said that the upstream is gone.
+   (merge 05e7368 jc/checkout-local-track-report later to maint).
+
+ * With The git-prompt support (in contrib/), using the exit status of
+   the last command in the prompt, e.g.  PS1='$(__git_ps1) $? ', did
+   not work well, because the helper function stomped on the exit
+   status.
+   (merge 6babe76 tf/prompt-preserve-exit-status later to maint).
+
+ * Recent update to "git commit" broke amending an existing commit
+   with bogus author/committer lines without a valid e-mail address.
+   (merge c83a509 jk/commit-date-approxidate later to maint).
+
+ * The lockfile API used to get confused which file to clean up when
+   the process moved the $cwd after creating a lockfile.
+   (merge fa137f6 nd/lockfile-absolute later to maint).
+
+ * Traditionally we tried to avoid interpreting date strings given by
+   the user as future dates, e.g. GIT_COMMITTER_DATE=2014-12-10 when
+   used early November 2014 was taken as "October 12, 2014" because it
+   is likely that a date in the future, December 10, is a mistake.
+   This heuristics has been loosened to allow people to express future
+   dates (most notably, --until=<date> may want to be far in the
+   future) and we no longer tiebreak by future-ness of the date when
+
+    (1) ISO-like format is used, and
+    (2) the string can make sense interpreted as both y-m-d and y-d-m.
+
+   Git may still have to use the heuristics to tiebreak between dd/mm/yy
+   and mm/dd/yy, though.
+   (merge d372395 jk/approxidate-avoid-y-d-m-over-future-dates later to maint).
+
+ * Git did not correctly read an overlong refname from a packed refs
+   file.
+   (merge ea41783 jk/read-packed-refs-without-path-max later to maint).
+
+ * "git apply" was described in the documentation to take --ignore-date
+   option, which it does not.
+   (merge 0cef4e7 rw/apply-does-not-take-ignore-date later to maint).
+
+ * "git add -i" did not notice when the interactive command input
+   stream went away and kept asking the same question.
+   (merge a8bec7a jk/add-i-read-error later to maint).
+
+ * "git send-email" did not handle RFC 2047 encoded headers quite
+   right.
+   (merge ab47e2a rd/send-email-2047-fix later to maint).
+
+ * New tag object format validation added in 2.2 showed garbage after
+   a tagname it reported in its error message.
+   (merge a1e920a js/fsck-tag-validation later to maint).
+
+ * The code that reads the reflog from the newer to the older entries
+   did not handle an entry that crosses a boundary of block it uses to
+   read them correctly.
+   (merge 69216bf jk/for-each-reflog-ent-reverse later to maint).
+
+ * "git diff -B -M" after making a new copy B out of an existing file
+   A and then editing A extensively ought to report that B was created
+   by copying A and A was modified, which is what "git diff -C"
+   reports, but it instead said A was renamed to B and A was edited
+   heavily in place.  This was not just incoherent but also failed to
+   apply with "git apply".  The report has been corrected to match what
+   "git diff -C" produces for this case.
+   (merge 6936b58 jc/diff-b-m later to maint).
+
+ * In files we pre-populate for the user to edit with commented hints,
+   a line of hint that is indented with a tab used to show as '#' (or
+   any comment char), ' ' (space), and then the hint text that began
+   with the tab, which some editors flag as an indentation error (tab
+   following space).  We now omit the space after the comment char in
+   such a case.
+   (merge d55aeb7 jc/strbuf-add-lines-avoid-sp-ht-sequence later to maint).
+
+ * "git ls-tree" does not support path selection based on negative
+   pathspecs, but did not error out when negative pathspecs are given.
+   (merge f1f6224 nd/ls-tree-pathspec later to maint).
+
+ * The function sometimes returned a non-freeable memory and some
+   other times returned a piece of memory that must be freed, leading

-Long version:
-
-I started reading over the SubmittingPatches document for Linux
-kernel, primarily because I wanted to have a document similar to
-it for the core GIT to make sure people understand what they are
-doing when they write "Signed-off-by" line.
-
-But the patch submission requirements are a lot more relaxed
-here on the technical/contents front, because the core GIT is
-thousand times smaller ;-).  So here is only the relevant bits.
+Here are some guidelines for people who want to contribute their code
+to this software.
 
+(0) Decide what to base your work on.
+
+In general, always base your work on the oldest branch that your
+change is relevant to.
+
+ - A bugfix should be based on 'maint' in general. If the bug is not
+   present in 'maint', base it on 'master'. For a bug that's not yet
+   in 'master', find the topic that introduces the regression, and
+   base your work on the tip of the topic.
+
+ - A new feature should be based on 'master' in general. If the new
+   feature depends on a topic that is in 'pu', but not in 'master',
+   base your work on the tip of that topic.
+
+ - Corrections and enhancements to a topic not yet in 'master' should
+   be based on the tip of that topic. If the topic has not been merged
+   to 'next', it's alright to add a note to squash minor corrections
+   into the series.
+
+ - In the exceptional case that a new feature depends on several topics
+   not in 'master', start working on 'next' or 'pu' privately and send
+   out patches for discussion. Before the final merge, you may have to
+   wait until some of the dependent topics graduate to 'master', and
+   rebase your work.
+
+ - Some parts of the system have dedicated maintainers with their own
+   repositories (see the section "Subsystems" below).  Changes to
+   these parts should be based on their trees.
+
+To find the tip of a topic branch, run "git log --first-parent
+master..pu" and look for the merge commit. The second parent of this
+commit is the tip of the topic branch.

+Speaking of the documentation, it is currently a liberal mixture of US

+unfortunate.  A huge patch that touches the files all over the place
+only to correct the inconsistency is not welcome, though.  Potential

+favor of US English, with small and easily digestible patches, as a
+side effect of doing some other real work in the vicinity (e.g.

-By default, Thunderbird will both wrap emails as well as flag them as
-being 'format=flowed', both of which will make the resulting email unusable
-by git.
-
-Here are some hints on how to successfully submit patches inline using
-Thunderbird.
-
-There are two different approaches.  One approach is to configure
-Thunderbird to not mangle patches.  The second approach is to use
-an external editor to keep Thunderbird from mangling the patches.
-
-Approach #1 (configuration):
-
-This recipe is current as of Thunderbird 2.0.0.19.  Three steps:
-  1.  Configure your mail server composition as plain text
-      Edit...Account Settings...Composition & Addressing,
-        uncheck 'Compose Messages in HTML'.
-  2.  Configure your general composition window to not wrap
-      Edit..Preferences..Composition, wrap plain text messages at 0
-  3.  Disable the use of format=flowed
-      Edit..Preferences..Advanced..Config Editor.  Search for:
-        mailnews.send_plaintext_flowed
-      toggle it to make sure it is set to 'false'.
-
-After that is done, you should be able to compose email as you
-otherwise would (cut + paste, git-format-patch | git-imap-send, etc),
-and the patches should not be mangled.
-
-Approach #2 (external editor):
-
-This recipe appears to work with the current [*1*] Thunderbird from Suse.
-
-The following Thunderbird extensions are needed:
-	AboutConfig 0.5
-		http://aboutconfig.mozdev.org/
-	External Editor 0.7.2
-		http://globs.org/articles.php?lng=en&pg=8
-
-1) Prepare the patch as a text file using your method of choice.
-
-2) Before opening a compose window, use Edit->Account Settings to
-uncheck the "Compose messages in HTML format" setting in the
-"Composition & Addressing" panel of the account to be used to send the
-patch. [*2*]
-
-3) In the main Thunderbird window, _before_ you open the compose window
-for the patch, use Tools->about:config to set the following to the
-indicated values:
-	mailnews.send_plaintext_flowed	=> false
-	mailnews.wraplength		=> 0
-
-4) Open a compose window and click the external editor icon.
-
-5) In the external editor window, read in the patch file and exit the
-editor normally.
-
-6) Back in the compose window: Add whatever other text you wish to the
-message, complete the addressing and subject fields, and press send.
-
-7) Optionally, undo the about:config/account settings changes made in
-steps 2 & 3.

------
-
-GMail does not appear to have any way to turn off line wrapping in the web
-interface, so this will mangle any emails that you send.  You can however
-use any IMAP email client to connect to the google imap server, and forward
-the emails through that.  Just make sure to disable line wrapping in that
-email client.  Alternatively, use "git send-email" instead.
-
-Submitting properly formatted patches via Gmail is simple now that
-IMAP support is available. First, edit your ~/.gitconfig to specify your
-account settings:
-
-[imap]
-	folder = "[Gmail]/Drafts"
-	host = imaps://imap.gmail.com
-	user = user@gmail.com
-	pass = p4ssw0rd
-	port = 993
-	sslverify = false
-
-You might need to instead use: folder = "[Google Mail]/Drafts" if you get an error
-that the "Folder doesn't exist".
-
-Next, ensure that your Gmail settings are correct. In "Settings" the
-"Use Unicode (UTF-8) encoding for outgoing messages" should be checked.
-
-Once your commits are ready to send to the mailing list, run the following
-command to send the patch emails to your Gmail Drafts folder.
-
-	$ git format-patch -M --stdout origin/master | git imap-send

+
+http.<url>.*::
+	Any of the http.* options above can be applied selectively to some URLs.
+	For a config key to match a URL, each element of the config key is
+	compared to that of the URL, in the following order:
++
+--
+. Scheme (e.g., `https` in `https://example.com/`). This field
+  must match exactly between the config key and the URL.
+
+. Host/domain name (e.g., `example.com` in `https://example.com/`).
+  This field must match exactly between the config key and the URL.
+
+. Port number (e.g., `8080` in `http://example.com:8080/`).
+  This field must match exactly between the config key and the URL.
+  Omitted port numbers are automatically converted to the correct
+  default for the scheme before matching.
+
+. Path (e.g., `repo.git` in `https://example.com/repo.git`). The
+  path field of the config key must match the path field of the URL
+  either exactly or as a prefix of slash-delimited path elements.  This means
+  a config key with path `foo/` matches URL path `foo/bar`.  A prefix can only
+  match on a slash (`/`) boundary.  Longer matches take precedence (so a config
+  key with path `foo/bar` is a better match to URL path `foo/bar` than a config
+  key with just path `foo/`).
+
+. User name (e.g., `user` in `https://user@example.com/repo.git`). If
+  the config key has a user name it must match the user name in the
+  URL exactly. If the config key does not have a user name, that
+  config key will match a URL with any user name (including none),
+  but at a lower precedence than a config key with a user name.
+--
++
+The list above is ordered by decreasing precedence; a URL that matches
+a config key's path is preferred to one that matches its user name. For example,
+if the URL is `https://user@example.com/foo/bar` a config key match of
+`https://example.com/foo` will be preferred over a config key match of
+`https://user@example.com`.
++
+All URLs are normalized before attempting any matching (the password part,
+if embedded in the URL, is always ignored for matching purposes) so that
+equivalent URLs that are simply spelled differently will match properly.
+Environment variable settings always override any matches.  The URLs that are
+matched against are those given directly to Git commands.  This means any URLs
+visited as a result of a redirection do not participate in matching.

+	and friends. The defaults can be overridden on the command line
+	(using `--dirstat=<param1,param2,...>`). The fallback defaults
+	(when not changed by `diff.dirstat`) are `changes,noncumulative,3`.
+	The following parameters are available:
++
+--
+`changes`;;
+	Compute the dirstat numbers by counting the lines that have been
+	removed from the source, or added to the destination. This ignores
+	the amount of pure code movements within a file.  In other words,
+	rearranging lines in a file is not counted as much as other changes.
+	This is the default behavior when no parameter is given.
+`lines`;;
+	Compute the dirstat numbers by doing the regular line-based diff
+	analysis, and summing the removed/added line counts. (For binary
+	files, count 64-byte chunks instead, since binary files have no
+	natural concept of lines). This is a more expensive `--dirstat`
+	behavior than the `changes` behavior, but it does count rearranged
+	lines within a file as much as other changes. The resulting output
+	is consistent with what you get from the other `--*stat` options.
+`files`;;
+	Compute the dirstat numbers by counting the number of files changed.
+	Each changed file counts equally in the dirstat analysis. This is
+	the computationally cheapest `--dirstat` behavior, since it does
+	not have to look at the file contents at all.
+`cumulative`;;
+	Count changes in a child directory for the parent directory as well.
+	Note that when using `cumulative`, the sum of the percentages
+	reported may exceed 100%. The default (non-cumulative) behavior can
+	be specified with the `noncumulative` parameter.
+<limit>;;
+	An integer parameter specifies a cut-off percent (3% by default).
+	Directories contributing less than this percentage of the changes
+	are not shown in the output.
+--
++
+Example: The following will count changed files, while ignoring
+directories with less than 10% of the total amount of changed files,
+and accumulating child directory counts in the parent directories:
+`files,10,cumulative`.
+
+diff.statGraphWidth::
+	Limit the width of the graph part in --stat output. If set, applies
+	to all commands generating --stat output except format-patch.
+
+diff.context::
+	Generate diffs with <n> lines of context instead of the default
+	of 3. This value is overridden by the -U option.
+
+diff.external::
+	If this config variable is set, diff generation is not
+	performed using the internal diff machinery, but using the
+	given command.  Can be overridden with the `GIT_EXTERNAL_DIFF'
+	environment variable.  The command is called with parameters
+	as described under "git Diffs" in linkgit:git[1].  Note: if
+	you want to use an external diff program only on a subset of

+
+diff.ignoreSubmodules::
+	Sets the default value of --ignore-submodules. Note that this
+	affects only 'git diff' Porcelain, and not lower level 'diff'
+	commands such as 'git diff-files'. 'git checkout' also honors
+	this setting when reporting uncommitted changes. Setting it to
+	'all' disables the submodule summary normally shown by 'git commit'
+	and 'git status' when 'status.submodulesummary' is set unless it is
+	overridden by using the --ignore-submodules command-line option.
+	The 'git submodule' commands are not affected by this setting.
+
+diff.mnemonicprefix::
+	If set, 'git diff' uses a prefix pair that is different from the
+	standard "a/" and "b/" depending on what is being compared.  When
+	this configuration is in effect, reverse diff output also swaps
+	the order of the prefixes:
+`git diff`;;
+	compares the (i)ndex and the (w)ork tree;
+`git diff HEAD`;;
+	 compares a (c)ommit and the (w)ork tree;
+`git diff --cached`;;

+`git diff HEAD:file1 file2`;;
+	compares an (o)bject and a (w)ork tree entity;
+`git diff --no-index a b`;;
+	compares two non-git things (1) and (2).
+
+diff.noprefix::
+	If set, 'git diff' does not show any source or destination prefix.
+
+diff.orderfile::
+	File indicating how to order files within a diff, using
+	one shell glob pattern per line.

+
+diff.renames::
+	Tells Git to detect renames.  If set to any boolean value, it
+	will enable basic rename detection.  If set to "copies" or
+	"copy", it will detect copies, as well.
+
+diff.suppressBlankEmpty::
+	A boolean to inhibit the standard behavior of printing a space
+	before each empty output line. Defaults to false.
+
+diff.submodule::
+	Specify the format in which differences in submodules are
+	shown.  The "log" format lists the commits in the range like
+	linkgit:git-submodule[1] `summary` does.  The "short" format

+	The following parameters are available:
++
+--
+`changes`;;
+	Compute the dirstat numbers by counting the lines that have been

+	Compute the dirstat numbers by doing the regular line-based diff
+	analysis, and summing the removed/added line counts. (For binary
+	files, count 64-byte chunks instead, since binary files have no
+	natural concept of lines). This is a more expensive `--dirstat`
+	behavior than the `changes` behavior, but it does count rearranged
+	lines within a file as much as other changes. The resulting output
+	is consistent with what you get from the other `--*stat` options.
+`files`;;
+	Compute the dirstat numbers by counting the number of files changed.
+	Each changed file counts equally in the dirstat analysis. This is
+	the computationally cheapest `--dirstat` behavior, since it does
+	not have to look at the file contents at all.
+`cumulative`;;
+	Count changes in a child directory for the parent directory as well.
+	Note that when using `cumulative`, the sum of the percentages
+	reported may exceed 100%. The default (non-cumulative) behavior can
+	be specified with the `noncumulative` parameter.

-------------------------------------
-
-Everybody uses these commands to maintain git repositories.
-
-  * linkgit:git-init[1] or linkgit:git-clone[1] to create a
-    new repository.
-
-  * linkgit:git-fsck[1] to check the repository for errors.
-
-  * linkgit:git-gc[1] to do common housekeeping tasks such as
-    repack and prune.
-
-Examples
-~~~~~~~~
-
-Check health and remove cruft.::
-+
-------------
-$ git fsck <1>
-$ git count-objects <2>
-$ git gc <3>
-------------
-+
-<1> running without `\--full` is usually cheap and assures the
-repository health reasonably well.
-<2> check how many loose objects there are and how much
-disk space is wasted by not repacking.
-<3> repacks the local repository and performs other housekeeping tasks.
-
-Repack a small project into single pack.::
-+
-------------
-$ git gc <1>
-------------
-+
-<1> pack all the objects reachable from the refs into one pack,
-then remove the other packs.
-
-
-Individual Developer (Standalone)[[Individual Developer (Standalone)]]
-----------------------------------------------------------------------
-
-A standalone individual developer does not exchange patches with
-other people, and works alone in a single repository, using the
-following commands.
-
-  * linkgit:git-show-branch[1] to see where you are.
-
-  * linkgit:git-log[1] to see what happened.
-
-  * linkgit:git-checkout[1] and linkgit:git-branch[1] to switch
-    branches.
-
-  * linkgit:git-add[1] to manage the index file.
-
-  * linkgit:git-diff[1] and linkgit:git-status[1] to see what
-    you are in the middle of doing.
-
-  * linkgit:git-commit[1] to advance the current branch.
-
-  * linkgit:git-reset[1] and linkgit:git-checkout[1] (with
-    pathname parameters) to undo changes.
-
-  * linkgit:git-merge[1] to merge between local branches.
-
-  * linkgit:git-rebase[1] to maintain topic branches.
-
-  * linkgit:git-tag[1] to mark known point.
-
-Examples
-~~~~~~~~
-
-Use a tarball as a starting point for a new repository.::
-+
-------------
-$ tar zxf frotz.tar.gz
-$ cd frotz
-$ git init
-$ git add . <1>
-$ git commit -m "import of frotz source tree."
-$ git tag v2.43 <2>
-------------
-+
-<1> add everything under the current directory.
-<2> make a lightweight, unannotated tag.
-
-Create a topic branch and develop.::
-+
-------------
-$ git checkout -b alsa-audio <1>
-$ edit/compile/test
-$ git checkout -- curses/ux_audio_oss.c <2>
-$ git add curses/ux_audio_alsa.c <3>
-$ edit/compile/test
-$ git diff HEAD <4>
-$ git commit -a -s <5>
-$ edit/compile/test
-$ git reset --soft HEAD^ <6>
-$ edit/compile/test
-$ git diff ORIG_HEAD <7>
-$ git commit -a -c ORIG_HEAD <8>
-$ git checkout master <9>
-$ git merge alsa-audio <10>
-$ git log --since='3 days ago' <11>
-$ git log v2.43.. curses/ <12>
-------------
-+
-<1> create a new topic branch.
-<2> revert your botched changes in `curses/ux_audio_oss.c`.
-<3> you need to tell git if you added a new file; removal and
-modification will be caught if you do `git commit -a` later.
-<4> to see what changes you are committing.
-<5> commit everything as you have tested, with your sign-off.
-<6> take the last commit back, keeping what is in the working tree.
-<7> look at the changes since the premature commit we took back.
-<8> redo the commit undone in the previous step, using the message
-you originally wrote.
-<9> switch to the master branch.
-<10> merge a topic branch into your master branch.
-<11> review commit logs; other forms to limit output can be
-combined and include `\--max-count=10` (show 10 commits),
-`\--until=2005-12-10`, etc.
-<12> view only the changes that touch what's in `curses/`
-directory, since `v2.43` tag.
-
-
-Individual Developer (Participant)[[Individual Developer (Participant)]]
-------------------------------------------------------------------------
-
-A developer working as a participant in a group project needs to
-learn how to communicate with others, and uses these commands in
-addition to the ones needed by a standalone developer.
-
-  * linkgit:git-clone[1] from the upstream to prime your local
-    repository.
-
-  * linkgit:git-pull[1] and linkgit:git-fetch[1] from "origin"
-    to keep up-to-date with the upstream.
-
-  * linkgit:git-push[1] to shared repository, if you adopt CVS
-    style shared repository workflow.
-
-  * linkgit:git-format-patch[1] to prepare e-mail submission, if
-    you adopt Linux kernel-style public forum workflow.
-
-Examples
-~~~~~~~~
-
-Clone the upstream and work on it.  Feed changes to upstream.::
-+
-------------
-$ git clone git://git.kernel.org/pub/scm/.../torvalds/linux-2.6 my2.6
-$ cd my2.6
-$ edit/compile/test; git commit -a -s <1>
-$ git format-patch origin <2>
-$ git pull <3>
-$ git log -p ORIG_HEAD.. arch/i386 include/asm-i386 <4>
-$ git pull git://git.kernel.org/pub/.../jgarzik/libata-dev.git ALL <5>
-$ git reset --hard ORIG_HEAD <6>
-$ git gc <7>
-$ git fetch --tags <8>
-------------
-+
-<1> repeat as needed.
-<2> extract patches from your branch for e-mail submission.
-<3> `git pull` fetches from `origin` by default and merges into the
-current branch.
-<4> immediately after pulling, look at the changes done upstream
-since last time we checked, only in the
-area we are interested in.
-<5> fetch from a specific branch from a specific repository and merge.
-<6> revert the pull.
-<7> garbage collect leftover objects from reverted pull.
-<8> from time to time, obtain official tags from the `origin`
-and store them under `.git/refs/tags/`.
-
-
-Push into another repository.::
-+
-------------
-satellite$ git clone mothership:frotz frotz <1>
-satellite$ cd frotz
-satellite$ git config --get-regexp '^(remote|branch)\.' <2>
-remote.origin.url mothership:frotz
-remote.origin.fetch refs/heads/*:refs/remotes/origin/*
-branch.master.remote origin
-branch.master.merge refs/heads/master
-satellite$ git config remote.origin.push \
-           master:refs/remotes/satellite/master <3>
-satellite$ edit/compile/test/commit
-satellite$ git push origin <4>
-
-mothership$ cd frotz
-mothership$ git checkout master
-mothership$ git merge satellite/master <5>
-------------
-+
-<1> mothership machine has a frotz repository under your home
-directory; clone from it to start a repository on the satellite
-machine.
-<2> clone sets these configuration variables by default.
-It arranges `git pull` to fetch and store the branches of mothership
-machine to local `remotes/origin/*` tracking branches.
-<3> arrange `git push` to push local `master` branch to
-`remotes/satellite/master` branch of the mothership machine.
-<4> push will stash our work away on `remotes/satellite/master`
-tracking branch on the mothership machine.  You could use this as
-a back-up method.
-<5> on mothership machine, merge the work done on the satellite
-machine into the master branch.
-
-Branch off of a specific tag.::
-+
-------------
-$ git checkout -b private2.6.14 v2.6.14 <1>
-$ edit/compile/test; git commit -a
-$ git checkout master
-$ git format-patch -k -m --stdout v2.6.14..private2.6.14 |
-  git am -3 -k <2>
-------------
-+
-<1> create a private branch based on a well known (but somewhat behind)
-tag.
-<2> forward port all changes in `private2.6.14` branch to `master` branch
-without a formal "merging".
-
-
-Integrator[[Integrator]]
-------------------------
-
-A fairly central person acting as the integrator in a group
-project receives changes made by others, reviews and integrates
-them and publishes the result for others to use, using these
-commands in addition to the ones needed by participants.
-
-  * linkgit:git-am[1] to apply patches e-mailed in from your
-    contributors.
-
-  * linkgit:git-pull[1] to merge from your trusted lieutenants.
-
-  * linkgit:git-format-patch[1] to prepare and send suggested
-    alternative to contributors.
-
-  * linkgit:git-revert[1] to undo botched commits.
-
-  * linkgit:git-push[1] to publish the bleeding edge.
-
-
-Examples
-~~~~~~~~
-
-My typical GIT day.::
-+
-------------
-$ git status <1>
-$ git show-branch <2>
-$ mailx <3>
-& s 2 3 4 5 ./+to-apply
-& s 7 8 ./+hold-linus
-& q
-$ git checkout -b topic/one master
-$ git am -3 -i -s -u ./+to-apply <4>
-$ compile/test
-$ git checkout -b hold/linus && git am -3 -i -s -u ./+hold-linus <5>
-$ git checkout topic/one && git rebase master <6>
-$ git checkout pu && git reset --hard next <7>
-$ git merge topic/one topic/two && git merge hold/linus <8>
-$ git checkout maint
-$ git cherry-pick master~4 <9>
-$ compile/test
-$ git tag -s -m "GIT 0.99.9x" v0.99.9x <10>
-$ git fetch ko && git show-branch master maint 'tags/ko-*' <11>
-$ git push ko <12>
-$ git push ko v0.99.9x <13>
-------------
-+
-<1> see what I was in the middle of doing, if any.
-<2> see what topic branches I have and think about how ready
-they are.
-<3> read mails, save ones that are applicable, and save others
-that are not quite ready.
-<4> apply them, interactively, with my sign-offs.
-<5> create topic branch as needed and apply, again with my
-sign-offs.
-<6> rebase internal topic branch that has not been merged to the
-master, nor exposed as a part of a stable branch.
-<7> restart `pu` every time from the next.
-<8> and bundle topic branches still cooking.
-<9> backport a critical fix.
-<10> create a signed tag.
-<11> make sure I did not accidentally rewind master beyond what I
-already pushed out.  `ko` shorthand points at the repository I have
-at kernel.org, and looks like this:
-+
-------------
-$ cat .git/remotes/ko
-URL: kernel.org:/pub/scm/git/git.git
-Pull: master:refs/tags/ko-master
-Pull: next:refs/tags/ko-next
-Pull: maint:refs/tags/ko-maint
-Push: master
-Push: next
-Push: +pu
-Push: maint
-------------
-+
-In the output from `git show-branch`, `master` should have
-everything `ko-master` has, and `next` should have
-everything `ko-next` has.
-
-<12> push out the bleeding edge.
-<13> push the tag out, too.
-
-
-Repository Administration[[Repository Administration]]
-------------------------------------------------------
-
-A repository administrator uses the following tools to set up
-and maintain access to the repository by developers.
-
-  * linkgit:git-daemon[1] to allow anonymous download from
-    repository.
-
-  * linkgit:git-shell[1] can be used as a 'restricted login shell'
-    for shared central repository users.
-
-link:howto/update-hook-example.txt[update hook howto] has a good
-example of managing a shared central repository.
-
-
-Examples
-~~~~~~~~
-We assume the following in /etc/services::
-+
-------------
-$ grep 9418 /etc/services
-git		9418/tcp		# Git Version Control System
-------------
-
-Run git-daemon to serve /pub/scm from inetd.::
-+
-------------
-$ grep git /etc/inetd.conf
-git	stream	tcp	nowait	nobody \
-  /usr/bin/git-daemon git-daemon --inetd --export-all /pub/scm
-------------
-+
-The actual configuration line should be on one line.
-
-Run git-daemon to serve /pub/scm from xinetd.::
-+
-------------
-$ cat /etc/xinetd.d/git-daemon
-# default: off
-# description: The git server offers access to git repositories
-service git
-{
-        disable = no
-        type            = UNLISTED
-        port            = 9418
-        socket_type     = stream
-        wait            = no
-        user            = nobody
-        server          = /usr/bin/git-daemon
-        server_args     = --inetd --export-all --base-path=/pub/scm
-        log_on_failure  += USERID
-}
-------------
-+
-Check your xinetd(8) documentation and setup, this is from a Fedora system.
-Others might be different.
-
-Give push/pull only access to developers.::
-+
-------------
-$ grep git /etc/passwd <1>
-alice:x:1000:1000::/home/alice:/usr/bin/git-shell
-bob:x:1001:1001::/home/bob:/usr/bin/git-shell
-cindy:x:1002:1002::/home/cindy:/usr/bin/git-shell
-david:x:1003:1003::/home/david:/usr/bin/git-shell
-$ grep git /etc/shells <2>
-/usr/bin/git-shell
-------------
-+
-<1> log-in shell is set to /usr/bin/git-shell, which does not
-allow anything but `git push` and `git pull`.  The users should
-get an ssh access to the machine.
-<2> in many distributions /etc/shells needs to list what is used
-as the login shell.
-
-CVS-style shared repository.::
-+
-------------
-$ grep git /etc/group <1>
-git:x:9418:alice,bob,cindy,david
-$ cd /home/devo.git
-$ ls -l <2>
-  lrwxrwxrwx   1 david git    17 Dec  4 22:40 HEAD -> refs/heads/master
-  drwxrwsr-x   2 david git  4096 Dec  4 22:40 branches

-  drwxrwsr-x   4 david git  4096 Dec  4 22:40 objects
-  drwxrwsr-x   4 david git  4096 Nov  7 14:58 refs
-  drwxrwsr-x   2 david git  4096 Dec  4 22:40 remotes
-$ ls -l hooks/update <3>
-  -r-xr-xr-x   1 david git  3536 Dec  4 22:40 update
-$ cat info/allowed-users <4>
-refs/heads/master	alice\|cindy
-refs/heads/doc-update	bob
-refs/tags/v[0-9]*	david
-------------
-+
-<1> place the developers into the same git group.
-<2> and make the shared repository writable by the group.
-<3> use update-hook example by Carl from Documentation/howto/
-for branch policy control.
-<4> alice and cindy can push into master, only bob can push into doc-update.
-david is the release manager and is the only person who can
-create and push version tags.
-
-HTTP server to support dumb protocol transfer.::
-+
-------------
-dev$ git update-server-info <1>
-dev$ ftp user@isp.example.com <2>
-ftp> cp -r .git /home/user/myproject.git
-------------
-+
-<1> make sure your info/refs and objects/info/packs are up-to-date
-<2> upload to public HTTP server hosted by your ISP.

 DESCRIPTION
 -----------
-This command adds the current content of new or modified files to the
-index, thus staging that content for inclusion in the next commit.
+This command updates the index using the current content found in
+the working tree, to prepare the content staged for the next commit.
+It typically adds the current content of existing paths as a whole,
+but with some options it can also be used to add content with
+only part of the changes made to the working tree files applied, or
+remove paths that do not exist in the working tree anymore.
 
 The "index" holds a snapshot of the content of the working tree, and it
 is this snapshot that is taken as the contents of the next commit.  Thus
 after making any changes to the working directory, and before running
-the commit command, you must use the 'add' command to add any new or
+the commit command, you must use the `add` command to add any new or

+EDITING PATCHES
+---------------
+
+Invoking `git add -e` or selecting `e` from the interactive hunk
+selector will open a patch in your editor; after the editor exits, the
+result is applied to the index. You are free to make arbitrary changes
+to the patch, but note that some changes may have confusing results, or
+even result in a patch that cannot be applied.  If you want to abort the
+operation entirely (i.e., stage nothing new in the index), simply delete
+all lines of the patch. The list below describes some common things you
+may see in a patch, and which editing operations make sense on them.
+
+--
+added content::
+
+Added content is represented by lines beginning with "{plus}". You can
+prevent staging any addition lines by deleting them.
+
+removed content::
+
+Removed content is represented by lines beginning with "-". You can
+prevent staging their removal by converting the "-" to a " " (space).
+
+modified content::
+
+Modified content is represented by "-" lines (removing the old content)
+followed by "{plus}" lines (adding the replacement content). You can
+prevent staging the modification by converting "-" lines to " ", and
+removing "{plus}" lines. Beware that modifying only half of the pair is
+likely to introduce confusing changes to the index.
+--
+
+There are also more complex operations that can be performed. But beware
+that because the patch is applied only to the index and not the working
+tree, the working tree will appear to "undo" the change in the index.
+For example, introducing a new line into the index that is in neither
+the HEAD nor the working tree will stage the new line for commit, but
+the line will appear to be reverted in the working tree.
+
+Avoid using these constructs, or do so with extreme caution.
+
+--
+removing untouched content::
+
+Content which does not differ between the index and working tree may be
+shown on context lines, beginning with a " " (space).  You can stage
+context lines for removal by converting the space to a "-". The
+resulting working tree file will appear to re-add the content.
+
+modifying existing content::
+
+One can also modify context lines by staging them for removal (by
+converting " " to "-") and adding a "{plus}" line with the new content.
+Similarly, one can modify "{plus}" lines for existing additions or
+modifications. In all cases, the new modification will appear reverted
+in the working tree.
+
+new content::
+
+You may also add new content that does not exist in the patch; simply
+add new lines, each starting with "{plus}". The addition will appear
+reverted in the working tree.
+--
+
+There are also several operations which should be avoided entirely, as
+they will make the patch impossible to apply:
+
+* adding context (" ") or removal ("-") lines
+* deleting context or removal lines
+* modifying the contents of context or removal lines

+Fighting regressions with git bisect
+====================================
+:Author: Christian Couder
+:Email: chriscool@tuxfamily.org
+:Date: 2009/11/08
+
+Abstract
+--------
+
+"git bisect" enables software users and developers to easily find the
+commit that introduced a regression. We show why it is important to
+have good tools to fight regressions. We describe how "git bisect"
+works from the outside and the algorithms it uses inside. Then we
+explain how to take advantage of "git bisect" to improve current
+practices. And we discuss how "git bisect" could improve in the
+future.
+
+
+Introduction to "git bisect"
+----------------------------
+
+Git is a Distributed Version Control system (DVCS) created by Linus
+Torvalds and maintained by Junio Hamano.
+
+In Git like in many other Version Control Systems (VCS), the different
+states of the data that is managed by the system are called
+commits. And, as VCS are mostly used to manage software source code,
+sometimes "interesting" changes of behavior in the software are
+introduced in some commits.
+
+In fact people are specially interested in commits that introduce a
+"bad" behavior, called a bug or a regression. They are interested in
+these commits because a commit (hopefully) contains a very small set
+of source code changes. And it's much easier to understand and
+properly fix a problem when you only need to check a very small set of
+changes, than when you don't know where look in the first place.
+
+So to help people find commits that introduce a "bad" behavior, the
+"git bisect" set of commands was invented. And it follows of course
+that in "git bisect" parlance, commits where the "interesting
+behavior" is present are called "bad" commits, while other commits are
+called "good" commits. And a commit that introduce the behavior we are
+interested in is called a "first bad commit". Note that there could be
+more than one "first bad commit" in the commit space we are searching.
+
+So "git bisect" is designed to help find a "first bad commit". And to
+be as efficient as possible, it tries to perform a binary search.
+
+
+Fighting regressions overview
+-----------------------------
+
+Regressions: a big problem
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Regressions are a big problem in the software industry. But it's
+difficult to put some real numbers behind that claim.
+
+There are some numbers about bugs in general, like a NIST study in
+2002 <<1>> that said:
+
+_____________
+Software bugs, or errors, are so prevalent and so detrimental that
+they cost the U.S. economy an estimated $59.5 billion annually, or
+about 0.6 percent of the gross domestic product, according to a newly
+released study commissioned by the Department of Commerce's National
+Institute of Standards and Technology (NIST). At the national level,
+over half of the costs are borne by software users and the remainder
+by software developers/vendors.  The study also found that, although
+all errors cannot be removed, more than a third of these costs, or an
+estimated $22.2 billion, could be eliminated by an improved testing
+infrastructure that enables earlier and more effective identification
+and removal of software defects. These are the savings associated with
+finding an increased percentage (but not 100 percent) of errors closer
+to the development stages in which they are introduced. Currently,
+over half of all errors are not found until "downstream" in the
+development process or during post-sale software use.
+_____________
+
+And then:
+
+_____________
+Software developers already spend approximately 80 percent of
+development costs on identifying and correcting defects, and yet few
+products of any type other than software are shipped with such high
+levels of errors.
+_____________
+
+Eventually the conclusion started with:
+
+_____________
+The path to higher software quality is significantly improved software
+testing.
+_____________
+
+There are other estimates saying that 80% of the cost related to
+software is about maintenance <<2>>.
+
+Though, according to Wikipedia <<3>>:
+
+_____________
+A common perception of maintenance is that it is merely fixing
+bugs. However, studies and surveys over the years have indicated that
+the majority, over 80%, of the maintenance effort is used for
+non-corrective actions (Pigosky 1997). This perception is perpetuated
+by users submitting problem reports that in reality are functionality
+enhancements to the system.
+_____________
+
+But we can guess that improving on existing software is very costly
+because you have to watch out for regressions. At least this would
+make the above studies consistent among themselves.
+
+Of course some kind of software is developed, then used during some
+time without being improved on much, and then finally thrown away. In
+this case, of course, regressions may not be a big problem. But on the
+other hand, there is a lot of big software that is continually
+developed and maintained during years or even tens of years by a lot
+of people. And as there are often many people who depend (sometimes
+critically) on such software, regressions are a really big problem.
+
+One such software is the Linux kernel. And if we look at the Linux
+kernel, we can see that a lot of time and effort is spent to fight
+regressions. The release cycle start with a 2 weeks long merge
+window. Then the first release candidate (rc) version is tagged. And
+after that about 7 or 8 more rc versions will appear with around one
+week between each of them, before the final release.
+
+The time between the first rc release and the final release is
+supposed to be used to test rc versions and fight bugs and especially
+regressions. And this time is more than 80% of the release cycle
+time. But this is not the end of the fight yet, as of course it
+continues after the release.
+
+And then this is what Ingo Molnar (a well known Linux kernel
+developer) says about his use of git bisect:
+
+_____________
+I most actively use it during the merge window (when a lot of trees
+get merged upstream and when the influx of bugs is the highest) - and
+yes, there have been cases that i used it multiple times a day. My
+average is roughly once a day.
+_____________
+
+So regressions are fought all the time by developers, and indeed it is
+well known that bugs should be fixed as soon as possible, so as soon
+as they are found. That's why it is interesting to have good tools for
+this purpose.
+
+Other tools to fight regressions
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+So what are the tools used to fight regressions? They are nearly the
+same as those used to fight regular bugs. The only specific tools are
+test suites and tools similar as "git bisect".
+
+Test suites are very nice. But when they are used alone, they are
+supposed to be used so that all the tests are checked after each
+commit. This means that they are not very efficient, because many
+tests are run for no interesting result, and they suffer from
+combinational explosion.
+
+In fact the problem is that big software often has many different
+configuration options and that each test case should pass for each
+configuration after each commit. So if you have for each release: N
+configurations, M commits and T test cases, you should perform:
+
+-------------
+N * M * T tests
+-------------
+
+where N, M and T are all growing with the size your software.
+
+So very soon it will not be possible to completely test everything.
+
+And if some bugs slip through your test suite, then you can add a test
+to your test suite. But if you want to use your new improved test
+suite to find where the bug slipped in, then you will either have to
+emulate a bisection process or you will perhaps bluntly test each
+commit backward starting from the "bad" commit you have which may be
+very wasteful.
+
+"git bisect" overview
+---------------------
+
+Starting a bisection
+~~~~~~~~~~~~~~~~~~~~
+
+The first "git bisect" subcommand to use is "git bisect start" to
+start the search. Then bounds must be set to limit the commit
+space. This is done usually by giving one "bad" and at least one
+"good" commit. They can be passed in the initial call to "git bisect
+start" like this:
+
+-------------
+$ git bisect start [BAD [GOOD...]]
+-------------
+
+or they can be set using:
+
+-------------
+$ git bisect bad [COMMIT]
+-------------
+
+and:
+
+-------------
+$ git bisect good [COMMIT...]
+-------------
+
+where BAD, GOOD and COMMIT are all names that can be resolved to a
+commit.
+
+Then "git bisect" will checkout a commit of its choosing and ask the
+user to test it, like this:
+
+-------------
+$ git bisect start v2.6.27 v2.6.25
+Bisecting: 10928 revisions left to test after this (roughly 14 steps)
+[2ec65f8b89ea003c27ff7723525a2ee335a2b393] x86: clean up using max_low_pfn on 32-bit
+-------------
+
+Note that the example that we will use is really a toy example, we
+will be looking for the first commit that has a version like
+"2.6.26-something", that is the commit that has a "SUBLEVEL = 26" line
+in the top level Makefile. This is a toy example because there are
+better ways to find this commit with Git than using "git bisect" (for
+example "git blame" or "git log -S<string>").
+
+Driving a bisection manually
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+At this point there are basically 2 ways to drive the search. It can
+be driven manually by the user or it can be driven automatically by a
+script or a command.
+
+If the user is driving it, then at each step of the search, the user
+will have to test the current commit and say if it is "good" or "bad"
+using the "git bisect good" or "git bisect bad" commands respectively
+that have been described above. For example:
+
+-------------
+$ git bisect bad
+Bisecting: 5480 revisions left to test after this (roughly 13 steps)
+[66c0b394f08fd89236515c1c84485ea712a157be] KVM: kill file->f_count abuse in kvm
+-------------
+
+And after a few more steps like that, "git bisect" will eventually
+find a first bad commit:
+
+-------------
+$ git bisect bad
+2ddcca36c8bcfa251724fe342c8327451988be0d is the first bad commit

+
+:100644 100644 5cf82581... 4492984e... M      Makefile
+-------------
+
+At this point we can see what the commit does, check it out (if it's
+not already checked out) or tinker with it, for example:
+
+-------------
+$ git show HEAD

+bisect run success
+-------------
+
+In this example, we passed "grep '^SUBLEVEL = 25' Makefile" as
+parameter to "git bisect run". This means that at each step, the grep
+command we passed will be launched. And if it exits with code 0 (that
+means success) then git bisect will mark the current state as
+"good". If it exits with code 1 (or any code between 1 and 127
+included, except the special code 125), then the current state will be
+marked as "bad".
+
+Exit code between 128 and 255 are special to "git bisect run". They
+make it stop immediately the bisection process. This is useful for
+example if the command passed takes too long to complete, because you
+can kill it with a signal and it will stop the bisection process.
+
+It can also be useful in scripts passed to "git bisect run" to "exit
+255" if some very abnormal situation is detected.
+
+Avoiding untestable commits
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Sometimes it happens that the current state cannot be tested, for
+example if it does not compile because there was a bug preventing it
+at that time. This is what the special exit code 125 is for. It tells
+"git bisect run" that the current commit should be marked as
+untestable and that another one should be chosen and checked out.
+
+If the bisection process is driven manually, you can use "git bisect
+skip" to do the same thing. (In fact the special exit code 125 makes
+"git bisect run" use "git bisect skip" in the background.)
+
+Or if you want more control, you can inspect the current state using
+for example "git bisect visualize". It will launch gitk (or "git log"
+if the DISPLAY environment variable is not set) to help you find a
+better bisection point.
+
+Either way, if you have a string of untestable commits, it might
+happen that the regression you are looking for has been introduced by
+one of these untestable commits. In this case it's not possible to
+tell for sure which commit introduced the regression.
+
+So if you used "git bisect skip" (or the run script exited with
+special code 125) you could get a result like this:
+
+-------------
+There are only 'skip'ped commits left to test.
+The first bad commit could be any of:
+15722f2fa328eaba97022898a305ffc8172db6b1
+78e86cf3e850bd755bb71831f42e200626fbd1e0

+070eab2303024706f2924822bfec8b9847e4ac1b
+We cannot bisect more!
+-------------
+
+Saving a log and replaying it
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you want to show other people your bisection process, you can get a
+log using for example:
+
+-------------
+$ git bisect log > bisect_log.txt
+-------------
+
+And it is possible to replay it using:
+
+-------------
+$ git bisect replay bisect_log.txt
+-------------
+
+
+"git bisect" details
+--------------------
+
+Bisection algorithm
+~~~~~~~~~~~~~~~~~~~
+
+As the Git commits form a directed acyclic graph (DAG), finding the
+best bisection commit to test at each step is not so simple. Anyway
+Linus found and implemented a "truly stupid" algorithm, later improved
+by Junio Hamano, that works quite well.
+
+So the algorithm used by "git bisect" to find the best bisection
+commit when there are no skipped commits is the following:
+
+1) keep only the commits that:
+
+a) are ancestor of the "bad" commit (including the "bad" commit itself),
+b) are not ancestor of a "good" commit (excluding the "good" commits).
+
+This means that we get rid of the uninteresting commits in the DAG.
+
+For example if we start with a graph like this:
+
+-------------
+G-Y-G-W-W-W-X-X-X-X
+	   \ /
+	    W-W-B
+	   /
+Y---G-W---W
+ \ /   \
+Y-Y     X-X-X-X
+
+-> time goes this way ->
+-------------
+
+where B is the "bad" commit, "G" are "good" commits and W, X, and Y
+are other commits, we will get the following graph after this first
+step:
+
+-------------
+W-W-W
+     \
+      W-W-B
+     /
+W---W
+-------------
+
+So only the W and B commits will be kept. Because commits X and Y will
+have been removed by rules a) and b) respectively, and because commits
+G are removed by rule b) too.
+
+Note for Git users, that it is equivalent as keeping only the commit
+given by:
+
+-------------
+git rev-list BAD --not GOOD1 GOOD2...
+-------------
+
+Also note that we don't require the commits that are kept to be
+descendants of a "good" commit. So in the following example, commits W
+and Z will be kept:
+
+-------------
+G-W-W-W-B
+   /
+Z-Z
+-------------
+
+2) starting from the "good" ends of the graph, associate to each
+commit the number of ancestors it has plus one
+
+For example with the following graph where H is the "bad" commit and A
+and D are some parents of some "good" commits:
+
+-------------
+A-B-C
+     \
+      F-G-H
+     /
+D---E
+-------------
+
+this will give:
+
+-------------
+1 2 3
+A-B-C
+     \6 7 8
+      F-G-H
+1   2/
+D---E
+-------------
+
+3) associate to each commit: min(X, N - X)
+
+where X is the value associated to the commit in step 2) and N is the
+total number of commits in the graph.
+
+In the above example we have N = 8, so this will give:
+
+-------------
+1 2 3
+A-B-C
+     \2 1 0
+      F-G-H
+1   2/
+D---E
+-------------
+
+4) the best bisection point is the commit with the highest associated
+number
+
+So in the above example the best bisection point is commit C.
+
+5) note that some shortcuts are implemented to speed up the algorithm
+
+As we know N from the beginning, we know that min(X, N - X) can't be
+greater than N/2. So during steps 2) and 3), if we would associate N/2
+to a commit, then we know this is the best bisection point. So in this
+case we can just stop processing any other commit and return the
+current commit.
+
+Bisection algorithm debugging
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For any commit graph, you can see the number associated with each
+commit using "git rev-list --bisect-all".
+
+For example, for the above graph, a command like:
+
+-------------
+$ git rev-list --bisect-all BAD --not GOOD1 GOOD2
+-------------
+
+would output something like:
+
+-------------
+e15b73ad3db9b48d7d1ade32f8cd23a751fe0ace (dist=3)
+15722f2fa328eaba97022898a305ffc8172db6b1 (dist=2)

+-------------
+
+Bisection algorithm discussed
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+First let's define "best bisection point". We will say that a commit X
+is a best bisection point or a best bisection commit if knowing its
+state ("good" or "bad") gives as much information as possible whether
+the state of the commit happens to be "good" or "bad".
+
+This means that the best bisection commits are the commits where the
+following function is maximum:
+
+-------------
+f(X) = min(information_if_good(X), information_if_bad(X))
+-------------
+
+where information_if_good(X) is the information we get if X is good
+and information_if_bad(X) is the information we get if X is bad.
+
+Now we will suppose that there is only one "first bad commit". This
+means that all its descendants are "bad" and all the other commits are
+"good". And we will suppose that all commits have an equal probability
+of being good or bad, or of being the first bad commit, so knowing the
+state of c commits gives always the same amount of information
+wherever these c commits are on the graph and whatever c is. (So we
+suppose that these commits being for example on a branch or near a
+good or a bad commit does not give more or less information).
+
+Let's also suppose that we have a cleaned up graph like one after step
+1) in the bisection algorithm above. This means that we can measure
+the information we get in terms of number of commit we can remove from
+the graph..
+
+And let's take a commit X in the graph.
+
+If X is found to be "good", then we know that its ancestors are all
+"good", so we want to say that:
+
+-------------
+information_if_good(X) = number_of_ancestors(X)  (TRUE)
+-------------
+
+And this is true because at step 1) b) we remove the ancestors of the
+"good" commits.
+
+If X is found to be "bad", then we know that its descendants are all
+"bad", so we want to say that:
+
+-------------
+information_if_bad(X) = number_of_descendants(X)  (WRONG)
+-------------
+
+But this is wrong because at step 1) a) we keep only the ancestors of
+the bad commit. So we get more information when a commit is marked as
+"bad", because we also know that the ancestors of the previous "bad"
+commit that are not ancestors of the new "bad" commit are not the
+first bad commit. We don't know if they are good or bad, but we know
+that they are not the first bad commit because they are not ancestor
+of the new "bad" commit.
+
+So when a commit is marked as "bad" we know we can remove all the
+commits in the graph except those that are ancestors of the new "bad"
+commit. This means that:
+
+-------------
+information_if_bad(X) = N - number_of_ancestors(X)  (TRUE)
+-------------
+
+where N is the number of commits in the (cleaned up) graph.
+
+So in the end this means that to find the best bisection commits we
+should maximize the function:
+
+-------------
+f(X) = min(number_of_ancestors(X), N - number_of_ancestors(X))
+-------------
+
+And this is nice because at step 2) we compute number_of_ancestors(X)
+and so at step 3) we compute f(X).
+
+Let's take the following graph as an example:
+
+-------------
+	    G-H-I-J
+	   /       \
+A-B-C-D-E-F         O
+	   \       /
+	    K-L-M-N
+-------------
+
+If we compute the following non optimal function on it:
+
+-------------
+g(X) = min(number_of_ancestors(X), number_of_descendants(X))
+-------------
+
+we get:
+
+-------------
+	    4 3 2 1
+	    G-H-I-J
+1 2 3 4 5 6/       \0
+A-B-C-D-E-F         O
+	   \       /
+	    K-L-M-N
+	    4 3 2 1
+-------------
+
+but with the algorithm used by git bisect we get:
+
+-------------
+	    7 7 6 5
+	    G-H-I-J
+1 2 3 4 5 6/       \0
+A-B-C-D-E-F         O
+	   \       /
+	    K-L-M-N
+	    7 7 6 5
+-------------
+
+So we chose G, H, K or L as the best bisection point, which is better
+than F. Because if for example L is bad, then we will know not only
+that L, M and N are bad but also that G, H, I and J are not the first
+bad commit (since we suppose that there is only one first bad commit
+and it must be an ancestor of L).
+
+So the current algorithm seems to be the best possible given what we
+initially supposed.
+
+Skip algorithm
+~~~~~~~~~~~~~~
+
+When some commits have been skipped (using "git bisect skip"), then
+the bisection algorithm is the same for step 1) to 3). But then we use
+roughly the following steps:
+
+6) sort the commit by decreasing associated value
+
+7) if the first commit has not been skipped, we can return it and stop
+here
+
+8) otherwise filter out all the skipped commits in the sorted list
+
+9) use a pseudo random number generator (PRNG) to generate a random
+number between 0 and 1
+
+10) multiply this random number with its square root to bias it toward
+0
+
+11) multiply the result by the number of commits in the filtered list
+to get an index into this list
+
+12) return the commit at the computed index
+
+Skip algorithm discussed
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+After step 7) (in the skip algorithm), we could check if the second
+commit has been skipped and return it if it is not the case. And in
+fact that was the algorithm we used from when "git bisect skip" was
+developed in Git version 1.5.4 (released on February 1st 2008) until
+Git version 1.6.4 (released July 29th 2009).
+
+But Ingo Molnar and H. Peter Anvin (another well known linux kernel
+developer) both complained that sometimes the best bisection points
+all happened to be in an area where all the commits are
+untestable. And in this case the user was asked to test many
+untestable commits, which could be very inefficient.
+
+Indeed untestable commits are often untestable because a breakage was
+introduced at one time, and that breakage was fixed only after many
+other commits were introduced.
+
+This breakage is of course most of the time unrelated to the breakage
+we are trying to locate in the commit graph. But it prevents us to
+know if the interesting "bad behavior" is present or not.
+
+So it is a fact that commits near an untestable commit have a high
+probability of being untestable themselves. And the best bisection
+commits are often found together too (due to the bisection algorithm).
+
+This is why it is a bad idea to just chose the next best unskipped
+bisection commit when the first one has been skipped.
+
+We found that most commits on the graph may give quite a lot of
+information when they are tested. And the commits that will not on
+average give a lot of information are the one near the good and bad
+commits.
+
+So using a PRNG with a bias to favor commits away from the good and
+bad commits looked like a good choice.
+
+One obvious improvement to this algorithm would be to look for a
+commit that has an associated value near the one of the best bisection
+commit, and that is on another branch, before using the PRNG. Because
+if such a commit exists, then it is not very likely to be untestable
+too, so it will probably give more information than a nearly randomly
+chosen one.
+
+Checking merge bases
+~~~~~~~~~~~~~~~~~~~~
+
+There is another tweak in the bisection algorithm that has not been
+described in the "bisection algorithm" above.
+
+We supposed in the previous examples that the "good" commits were
+ancestors of the "bad" commit. But this is not a requirement of "git
+bisect".
+
+Of course the "bad" commit cannot be an ancestor of a "good" commit,
+because the ancestors of the good commits are supposed to be
+"good". And all the "good" commits must be related to the bad commit.
+They cannot be on a branch that has no link with the branch of the
+"bad" commit. But it is possible for a good commit to be related to a
+bad commit and yet not be neither one of its ancestor nor one of its
+descendants.
+
+For example, there can be a "main" branch, and a "dev" branch that was
+forked of the main branch at a commit named "D" like this:
+
+-------------
+A-B-C-D-E-F-G  <--main
+       \
+	H-I-J  <--dev
+-------------
+
+The commit "D" is called a "merge base" for branch "main" and "dev"
+because it's the best common ancestor for these branches for a merge.
+
+Now let's suppose that commit J is bad and commit G is good and that
+we apply the bisection algorithm like it has been previously
+described.
+
+As described in step 1) b) of the bisection algorithm, we remove all
+the ancestors of the good commits because they are supposed to be good
+too.
+
+So we would be left with only:
+
+-------------
+H-I-J
+-------------
+
+But what happens if the first bad commit is "B" and if it has been
+fixed in the "main" branch by commit "F"?
+
+The result of such a bisection would be that we would find that H is
+the first bad commit, when in fact it's B. So that would be wrong!
+
+And yes it can happen in practice that people working on one branch
+are not aware that people working on another branch fixed a bug! It
+could also happen that F fixed more than one bug or that it is a
+revert of some big development effort that was not ready to be
+released.
+
+In fact development teams often maintain both a development branch and
+a maintenance branch, and it would be quite easy for them if "git
+bisect" just worked when they want to bisect a regression on the
+development branch that is not on the maintenance branch. They should
+be able to start bisecting using:
+
+-------------
+$ git bisect start dev main
+-------------
+
+To enable that additional nice feature, when a bisection is started
+and when some good commits are not ancestors of the bad commit, we
+first compute the merge bases between the bad and the good commits and
+we chose these merge bases as the first commits that will be checked
+out and tested.
+
+If it happens that one merge base is bad, then the bisection process
+is stopped with a message like:
+
+-------------
+The merge base BBBBBB is bad.
+This means the bug has been fixed between BBBBBB and [GGGGGG,...].
+-------------
+
+where BBBBBB is the sha1 hash of the bad merge base and [GGGGGG,...]
+is a comma separated list of the sha1 of the good commits.
+
+If some of the merge bases are skipped, then the bisection process
+continues, but the following message is printed for each skipped merge
+base:
+
+-------------
+Warning: the merge base between BBBBBB and [GGGGGG,...] must be skipped.
+So we cannot be sure the first bad commit is between MMMMMM and BBBBBB.
+We continue anyway.
+-------------
+
+where BBBBBB is the sha1 hash of the bad commit, MMMMMM is the sha1
+hash of the merge base that is skipped and [GGGGGG,...]  is a comma
+separated list of the sha1 of the good commits.
+
+So if there is no bad merge base, the bisection process continues as
+usual after this step.
+
+Best bisecting practices
+------------------------
+
+Using test suites and git bisect together
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you both have a test suite and use git bisect, then it becomes less
+important to check that all tests pass after each commit. Though of
+course it is probably a good idea to have some checks to avoid
+breaking too many things because it could make bisecting other bugs
+more difficult.
+
+You can focus your efforts to check at a few points (for example rc
+and beta releases) that all the T test cases pass for all the N
+configurations. And when some tests don't pass you can use "git
+bisect" (or better "git bisect run"). So you should perform roughly:
+
+-------------
+c * N * T + b * M * log2(M) tests
+-------------
+
+where c is the number of rounds of test (so a small constant) and b is
+the ratio of bug per commit (hopefully a small constant too).
+
+So of course it's much better as it's O(N * T) vs O(N * T * M) if
+you would test everything after each commit.
+
+This means that test suites are good to prevent some bugs from being
+committed and they are also quite good to tell you that you have some
+bugs. But they are not so good to tell you where some bugs have been
+introduced. To tell you that efficiently, git bisect is needed.
+
+The other nice thing with test suites, is that when you have one, you
+already know how to test for bad behavior. So you can use this
+knowledge to create a new test case for "git bisect" when it appears
+that there is a regression. So it will be easier to bisect the bug and
+fix it. And then you can add the test case you just created to your
+test suite.
+
+So if you know how to create test cases and how to bisect, you will be
+subject to a virtuous circle:
+
+more tests => easier to create tests => easier to bisect => more tests
+
+So test suites and "git bisect" are complementary tools that are very
+powerful and efficient when used together.
+
+Bisecting build failures
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can very easily automatically bisect broken builds using something
+like:
+
+-------------
+$ git bisect start BAD GOOD
+$ git bisect run make
+-------------
+
+Passing sh -c "some commands" to "git bisect run"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For example:
+
+-------------
+$ git bisect run sh -c "make || exit 125; ./my_app | grep 'good output'"
+-------------
+
+On the other hand if you do this often, then it can be worth having
+scripts to avoid too much typing.
+
+Finding performance regressions
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Here is an example script that comes slightly modified from a real
+world script used by Junio Hamano <<4>>.
+
+This script can be passed to "git bisect run" to find the commit that
+introduced a performance regression:
+
+-------------
+#!/bin/sh
+
+# Build errors are not what I am interested in.
+make my_app || exit 255
+
+# We are checking if it stops in a reasonable amount of time, so
+# let it run in the background...
+
+./my_app >log 2>&1 &
+
+# ... and grab its process ID.
+pid=$!
+
+# ... and then wait for sufficiently long.
+sleep $NORMAL_TIME
+
+# ... and then see if the process is still there.
+if kill -0 $pid
+then
+	# It is still running -- that is bad.
+	kill $pid; sleep 1; kill $pid;
+	exit 1
+else
+	# It has already finished (the $pid process was no more),
+	# and we are happy.
+	exit 0
+fi
+-------------
+
+Following general best practices
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+It is obviously a good idea not to have commits with changes that
+knowingly break things, even if some other commits later fix the
+breakage.
+
+It is also a good idea when using any VCS to have only one small
+logical change in each commit.
+
+The smaller the changes in your commit, the most effective "git
+bisect" will be. And you will probably need "git bisect" less in the
+first place, as small changes are easier to review even if they are
+only reviewed by the committer.
+
+Another good idea is to have good commit messages. They can be very
+helpful to understand why some changes were made.
+
+These general best practices are very helpful if you bisect often.
+
+Avoiding bug prone merges
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+First merges by themselves can introduce some regressions even when
+the merge needs no source code conflict resolution. This is because a
+semantic change can happen in one branch while the other branch is not
+aware of it.
+
+For example one branch can change the semantic of a function while the
+other branch add more calls to the same function.
+
+This is made much worse if many files have to be fixed to resolve
+conflicts. That's why such merges are called "evil merges". They can
+make regressions very difficult to track down. It can even be
+misleading to know the first bad commit if it happens to be such a
+merge, because people might think that the bug comes from bad conflict
+resolution when it comes from a semantic change in one branch.
+
+Anyway "git rebase" can be used to linearize history. This can be used
+either to avoid merging in the first place. Or it can be used to
+bisect on a linear history instead of the non linear one, as this
+should give more information in case of a semantic change in one
+branch.
+
+Merges can be also made simpler by using smaller branches or by using
+many topic branches instead of only long version related branches.
+
+And testing can be done more often in special integration branches
+like linux-next for the linux kernel.
+
+Adapting your work-flow
+~~~~~~~~~~~~~~~~~~~~~~~
+
+A special work-flow to process regressions can give great results.
+
+Here is an example of a work-flow used by Andreas Ericsson:
+
+* write, in the test suite, a test script that exposes the regression
+* use "git bisect run" to find the commit that introduced it
+* fix the bug that is often made obvious by the previous step
+* commit both the fix and the test script (and if needed more tests)
+
+And here is what Andreas said about this work-flow <<5>>:
+
+_____________
+To give some hard figures, we used to have an average report-to-fix
+cycle of 142.6 hours (according to our somewhat weird bug-tracker
+which just measures wall-clock time). Since we moved to Git, we've
+lowered that to 16.2 hours. Primarily because we can stay on top of
+the bug fixing now, and because everyone's jockeying to get to fix
+bugs (we're quite proud of how lazy we are to let Git find the bugs
+for us). Each new release results in ~40% fewer bugs (almost certainly
+due to how we now feel about writing tests).
+_____________
+
+Clearly this work-flow uses the virtuous circle between test suites
+and "git bisect". In fact it makes it the standard procedure to deal
+with regression.
+
+In other messages Andreas says that they also use the "best practices"
+described above: small logical commits, topic branches, no evil
+merge,... These practices all improve the bisectability of the commit
+graph, by making it easier and more useful to bisect.
+
+So a good work-flow should be designed around the above points. That
+is making bisecting easier, more useful and standard.
+
+Involving QA people and if possible end users
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+One nice about "git bisect" is that it is not only a developer
+tool. It can effectively be used by QA people or even end users (if
+they have access to the source code or if they can get access to all
+the builds).
+
+There was a discussion at one point on the linux kernel mailing list
+of whether it was ok to always ask end user to bisect, and very good
+points were made to support the point of view that it is ok.
+
+For example David Miller wrote <<6>>:
+
+_____________
+What people don't get is that this is a situation where the "end node
+principle" applies. When you have limited resources (here: developers)
+you don't push the bulk of the burden upon them. Instead you push
+things out to the resource you have a lot of, the end nodes (here:
+users), so that the situation actually scales.
+_____________
+
+This means that it is often "cheaper" if QA people or end users can do
+it.
+
+What is interesting too is that end users that are reporting bugs (or
+QA people that reproduced a bug) have access to the environment where
+the bug happens. So they can often more easily reproduce a
+regression. And if they can bisect, then more information will be
+extracted from the environment where the bug happens, which means that
+it will be easier to understand and then fix the bug.
+
+For open source projects it can be a good way to get more useful
+contributions from end users, and to introduce them to QA and
+development activities.
+
+Using complex scripts
+~~~~~~~~~~~~~~~~~~~~~
+
+In some cases like for kernel development it can be worth developing
+complex scripts to be able to fully automate bisecting.
+
+Here is what Ingo Molnar says about that <<7>>:
+
+_____________
+i have a fully automated bootup-hang bisection script. It is based on
+"git-bisect run". I run the script, it builds and boots kernels fully
+automatically, and when the bootup fails (the script notices that via
+the serial log, which it continuously watches - or via a timeout, if
+the system does not come up within 10 minutes it's a "bad" kernel),
+the script raises my attention via a beep and i power cycle the test
+box. (yeah, i should make use of a managed power outlet to 100%
+automate it)
+_____________
+
+Combining test suites, git bisect and other systems together
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+We have seen that test suites an git bisect are very powerful when
+used together. It can be even more powerful if you can combine them
+with other systems.
+
+For example some test suites could be run automatically at night with
+some unusual (or even random) configurations. And if a regression is
+found by a test suite, then "git bisect" can be automatically
+launched, and its result can be emailed to the author of the first bad
+commit found by "git bisect", and perhaps other people too. And a new
+entry in the bug tracking system could be automatically created too.
+
+
+The future of bisecting
+-----------------------
+
+"git replace"
+~~~~~~~~~~~~~
+
+We saw earlier that "git bisect skip" is now using a PRNG to try to
+avoid areas in the commit graph where commits are untestable. The
+problem is that sometimes the first bad commit will be in an
+untestable area.
+
+To simplify the discussion we will suppose that the untestable area is
+a simple string of commits and that it was created by a breakage
+introduced by one commit (let's call it BBC for bisect breaking
+commit) and later fixed by another one (let's call it BFC for bisect
+fixing commit).
+
+For example:
+
+-------------
+...-Y-BBC-X1-X2-X3-X4-X5-X6-BFC-Z-...
+-------------
+
+where we know that Y is good and BFC is bad, and where BBC and X1 to
+X6 are untestable.
+
+In this case if you are bisecting manually, what you can do is create
+a special branch that starts just before the BBC. The first commit in
+this branch should be the BBC with the BFC squashed into it. And the
+other commits in the branch should be the commits between BBC and BFC
+rebased on the first commit of the branch and then the commit after
+BFC also rebased on.
+
+For example:
+
+-------------
+      (BBC+BFC)-X1'-X2'-X3'-X4'-X5'-X6'-Z'
+     /
+...-Y-BBC-X1-X2-X3-X4-X5-X6-BFC-Z-...
+-------------
+
+where commits quoted with ' have been rebased.
+
+You can easily create such a branch with Git using interactive rebase.
+
+For example using:
+
+-------------
+$ git rebase -i Y Z
+-------------
+
+and then moving BFC after BBC and squashing it.
+
+After that you can start bisecting as usual in the new branch and you
+should eventually find the first bad commit.
+
+For example:
+
+-------------
+$ git bisect start Z' Y
+-------------
+
+If you are using "git bisect run", you can use the same manual fix up
+as above, and then start another "git bisect run" in the special
+branch. Or as the "git bisect" man page says, the script passed to
+"git bisect run" can apply a patch before it compiles and test the
+software <<8>>. The patch should turn a current untestable commits
+into a testable one. So the testing will result in "good" or "bad" and
+"git bisect" will be able to find the first bad commit. And the script
+should not forget to remove the patch once the testing is done before
+exiting from the script.
+
+(Note that instead of a patch you can use "git cherry-pick BFC" to
+apply the fix, and in this case you should use "git reset --hard
+HEAD^" to revert the cherry-pick after testing and before returning
+from the script.)
+
+But the above ways to work around untestable areas are a little bit
+clunky. Using special branches is nice because these branches can be
+shared by developers like usual branches, but the risk is that people
+will get many such branches. And it disrupts the normal "git bisect"
+work-flow. So, if you want to use "git bisect run" completely
+automatically, you have to add special code in your script to restart
+bisection in the special branches.
+
+Anyway one can notice in the above special branch example that the Z'
+and Z commits should point to the same source code state (the same
+"tree" in git parlance). That's because Z' result from applying the
+same changes as Z just in a slightly different order.
+
+So if we could just "replace" Z by Z' when we bisect, then we would
+not need to add anything to a script. It would just work for anyone in
+the project sharing the special branches and the replacements.
+
+With the example above that would give:
+
+-------------
+      (BBC+BFC)-X1'-X2'-X3'-X4'-X5'-X6'-Z'-...
+     /
+...-Y-BBC-X1-X2-X3-X4-X5-X6-BFC-Z
+-------------
+
+That's why the "git replace" command was created. Technically it
+stores replacements "refs" in the "refs/replace/" hierarchy. These
+"refs" are like branches (that are stored in "refs/heads/") or tags
+(that are stored in "refs/tags"), and that means that they can
+automatically be shared like branches or tags among developers.
+
+"git replace" is a very powerful mechanism. It can be used to fix
+commits in already released history, for example to change the commit
+message or the author. And it can also be used instead of git "grafts"
+to link a repository with another old repository.
+
+In fact it's this last feature that "sold" it to the Git community, so
+it is now in the "master" branch of Git's Git repository and it should
+be released in Git 1.6.5 in October or November 2009.
+
+One problem with "git replace" is that currently it stores all the
+replacements refs in "refs/replace/", but it would be perhaps better
+if the replacement refs that are useful only for bisecting would be in
+"refs/replace/bisect/". This way the replacement refs could be used
+only for bisecting, while other refs directly in "refs/replace/" would
+be used nearly all the time.
+
+Bisecting sporadic bugs
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Another possible improvement to "git bisect" would be to optionally
+add some redundancy to the tests performed so that it would be more
+reliable when tracking sporadic bugs.
+
+This has been requested by some kernel developers because some bugs
+called sporadic bugs do not appear in all the kernel builds because
+they are very dependent on the compiler output.
+
+The idea is that every 3 test for example, "git bisect" could ask the
+user to test a commit that has already been found to be "good" or
+"bad" (because one of its descendants or one of its ancestors has been
+found to be "good" or "bad" respectively). If it happens that a commit
+has been previously incorrectly classified then the bisection can be
+aborted early, hopefully before too many mistakes have been made. Then
+the user will have to look at what happened and then restart the
+bisection using a fixed bisect log.
+
+There is already a project called BBChop created by Ealdwulf Wuffinga
+on Github that does something like that using Bayesian Search Theory
+<<9>>:
+
+_____________
+BBChop is like 'git bisect' (or equivalent), but works when your bug
+is intermittent. That is, it works in the presence of false negatives
+(when a version happens to work this time even though it contains the
+bug). It assumes that there are no false positives (in principle, the
+same approach would work, but adding it may be non-trivial).
+_____________
+
+But BBChop is independent of any VCS and it would be easier for Git
+users to have something integrated in Git.
+
+Conclusion
+----------
+
+We have seen that regressions are an important problem, and that "git
+bisect" has nice features that complement very well practices and
+other tools, especially test suites, that are generally used to fight
+regressions. But it might be needed to change some work-flows and
+(bad) habits to get the most out of it.
+
+Some improvements to the algorithms inside "git bisect" are possible
+and some new features could help in some cases, but overall "git
+bisect" works already very well, is used a lot, and is already very
+useful. To back up that last claim, let's give the final word to Ingo
+Molnar when he was asked by the author how much time does he think
+"git bisect" saves him when he uses it:
+
+_____________
+a _lot_.
+
+About ten years ago did i do my first 'bisection' of a Linux patch
+queue. That was prior the Git (and even prior the BitKeeper) days. I
+literally days spent sorting out patches, creating what in essence
+were standalone commits that i guessed to be related to that bug.
+
+It was a tool of absolute last resort. I'd rather spend days looking
+at printk output than do a manual 'patch bisection'.
+
+With Git bisect it's a breeze: in the best case i can get a ~15 step
+kernel bisection done in 20-30 minutes, in an automated way. Even with
+manual help or when bisecting multiple, overlapping bugs, it's rarely
+more than an hour.
+
+In fact it's invaluable because there are bugs i would never even
+_try_ to debug if it wasn't for git bisect. In the past there were bug
+patterns that were immediately hopeless for me to debug - at best i
+could send the crash/bug signature to lkml and hope that someone else
+can think of something.
+
+And even if a bisection fails today it tells us something valuable
+about the bug: that it's non-deterministic - timing or kernel image
+layout dependent.
+
+So git bisect is unconditional goodness - and feel free to quote that
+;-)

+	The size, in bytes, that the object takes up on disk. See the
+	note about on-disk sizes in the `CAVEATS` section below.
+
+`deltabase`::
+	If the object is stored as a delta on-disk, this expands to the
+	40-hex sha1 of the delta base object. Otherwise, expands to the
+	null sha1 (40 zeroes). See `CAVEATS` below.
+
+`rest`::
+	If this atom is used in the output string, input lines are split
+	at the first whitespace boundary. All characters before that
+	whitespace are considered to be the object name; characters
+	after that first run of whitespace (i.e., the "rest" of the
+	line) are output in place of the `%(rest)` atom.
+
+If no format is specified, the default format is `%(objectname)
+%(objecttype) %(objectsize)`.
+
+If `--batch` is specified, the object information is followed by the
+object contents (consisting of `%(objectsize)` bytes), followed by a
+newline.
+
+For example, `--batch` without a custom format would produce:
 
 ------------
 <sha1> SP <type> SP <size> LF
 <contents> LF
 ------------
 
-If '--batch-check' is specified, output of the following form is printed for
-each object specified on stdin:
+Whereas `--batch-check='%(objectname) %(objecttype)'` would produce:
 
 ------------
-<sha1> SP <type> SP <size> LF
+<sha1> SP <type> LF
 ------------
 
-For both '--batch' and '--batch-check', output of the following form is printed
-for each object specified on stdin that does not exist in the repository:
+If a name is specified on stdin that cannot be resolved to an object in
+the repository, then `cat-file` will ignore any custom format and print:

+CAVEATS
+-------
+
+Note that the sizes of objects on disk are reported accurately, but care
+should be taken in drawing conclusions about which refs or objects are
+responsible for disk usage. The size of a packed non-delta object may be
+much larger than the size of objects which delta against it, but the
+choice of which object is the base and which is the delta is arbitrary
+and is subject to change during a repack.
+
+Note also that multiple copies of an object may be present in the object
+database; in this case, it is undefined which copy's size or delta base
+will be reported.

+===================
+
+NAME
+----
+git-check-ignore - Debug gitignore / exclude files
+
+
+SYNOPSIS
+--------
+[verse]
+'git check-ignore' [options] pathname...
+'git check-ignore' [options] --stdin < <list-of-paths>
+
+DESCRIPTION
+-----------
+
+For each pathname given via the command-line or from a file via
+`--stdin`, show the pattern from .gitignore (or other input files to
+the exclude mechanism) that decides if the pathname is excluded or
+included.  Later patterns within a file take precedence over earlier
+ones.
+
+By default, tracked files are not shown at all since they are not
+subject to exclude rules; but see `--no-index'.
+
+OPTIONS
+-------
+-q, --quiet::
+	Don't output anything, just set exit status.  This is only
+	valid with a single pathname.
+
+-v, --verbose::
+	Also output details about the matching pattern (if any)
+	for each given pathname.
+
+--stdin::
+	Read file names from stdin instead of from the command-line.
+
+-z::
+	The output format is modified to be machine-parseable (see
+	below).  If `--stdin` is also given, input paths are separated
+	with a NUL character instead of a linefeed character.
+
+-n, --non-matching::
+	Show given paths which don't match any pattern.	 This only
+	makes sense when `--verbose` is enabled, otherwise it would
+	not be possible to distinguish between paths which match a
+	pattern and those which don't.
+
+--no-index::
+	Don't look in the index when undertaking the checks. This can
+	be used to debug why a path became tracked by e.g. `git add .`
+	and was not ignored by the rules as expected by the user or when
+	developing patterns including negation to match a path previously
+	added with `git add -f`.
+
+OUTPUT
+------
+
+By default, any of the given pathnames which match an ignore pattern
+will be output, one per line.  If no pattern matches a given path,
+nothing will be output for that path; this means that path will not be
+ignored.
+
+If `--verbose` is specified, the output is a series of lines of the form:
+
+<source> <COLON> <linenum> <COLON> <pattern> <HT> <pathname>
+
+<pathname> is the path of a file being queried, <pattern> is the
+matching pattern, <source> is the pattern's source file, and <linenum>
+is the line number of the pattern within that source.  If the pattern
+contained a `!` prefix or `/` suffix, it will be preserved in the
+output.  <source> will be an absolute path when referring to the file
+configured by `core.excludesfile`, or relative to the repository root
+when referring to `.git/info/exclude` or a per-directory exclude file.
+
+If `-z` is specified, the pathnames in the output are delimited by the
+null character; if `--verbose` is also specified then null characters
+are also used instead of colons and hard tabs:
+
+<source> <NULL> <linenum> <NULL> <pattern> <NULL> <pathname> <NULL>
+
+If `-n` or `--non-matching` are specified, non-matching pathnames will
+also be output, in which case all fields in each output record except
+for <pathname> will be empty.  This can be useful when running
+non-interactively, so that files can be incrementally streamed to
+STDIN of a long-running check-ignore process, and for each of these
+files, STDOUT will indicate whether that file matched a pattern or
+not.  (Without this option, it would be impossible to tell whether the
+absence of output for a given file meant that it didn't match any
+pattern, or that the output hadn't been generated yet.)
+
+Buffering happens as documented under the `GIT_FLUSH` option in
+linkgit:git[1].  The caller is responsible for avoiding deadlocks
+caused by overfilling an input buffer or reading from an empty output
+buffer.
+

+

+	One or more of the provided paths is ignored.

 DESCRIPTION
 -----------
 Checks if a given 'refname' is acceptable, and exits with a non-zero
 status if it is not.
 
-A reference is used in git to specify branches and tags.  A
-branch head is stored under the `$GIT_DIR/refs/heads` directory, and
-a tag is stored under the `$GIT_DIR/refs/tags` directory.  git
-imposes the following rules on how references are named:
+A reference is used in Git to specify branches and tags.  A
+branch head is stored in the `refs/heads` hierarchy, while
+a tag is stored in the `refs/tags` hierarchy of the ref namespace
+(typically in `$GIT_DIR/refs/heads` and `$GIT_DIR/refs/tags`
+directories or, as entries in file `$GIT_DIR/packed-refs`
+if refs are packed by `git gc`).
+
+Git imposes the following rules on how references are named:
 
 . They can include slash `/` for hierarchical (directory)
   grouping, but no slash-separated component can begin with a
-  dot `.`.
+  dot `.` or end with the sequence `.lock`.
 
 . They must contain at least one `/`. This enforces the presence of a
   category like `heads/`, `tags/` etc. but the actual names are not
-  restricted.
+  restricted.  If the `--allow-onelevel` option is used, this rule
+  is waived.
 
 . They cannot have two consecutive dots `..` anywhere.
 
 . They cannot have ASCII control characters (i.e. bytes whose
   values are lower than \040, or \177 `DEL`), space, tilde `~`,
-  caret `{caret}`, colon `:`, question-mark `?`, asterisk `*`,
-  or open bracket `[` anywhere.
+  caret `^`, or colon `:` anywhere.
+
+. They cannot have question-mark `?`, asterisk `*`, or open
+  bracket `[` anywhere.  See the `--refspec-pattern` option below for
+  an exception to this rule.
 
-. They cannot end with a slash `/` nor a dot `.`.
+. They cannot begin or end with a slash `/` or contain multiple
+  consecutive slashes (see the `--normalize` option below for an
+  exception to this rule)
 
-. They cannot end with the sequence `.lock`.
+. They cannot end with a dot `.`.
 
 . They cannot contain a sequence `@{`.
 
-- They cannot contain a `\\`.
+. They cannot be the single character `@`.
+
+. They cannot contain a `\`.
 
 These rules make it easy for shell script based tools to parse
 reference names, pathname expansion by the shell when a reference name is used
 unquoted (by mistake), and also avoids ambiguities in certain
-reference name expressions (see linkgit:git-rev-parse[1]):
+reference name expressions (see linkgit:gitrevisions[7]):
 
 . A double-dot `..` is often used as in `ref1..ref2`, and in some
-  contexts this notation means `{caret}ref1 ref2` (i.e. not in
+  contexts this notation means `^ref1 ref2` (i.e. not in
   `ref1` and in `ref2`).
 
-. A tilde `~` and caret `{caret}` are used to introduce the postfix
+. A tilde `~` and caret `^` are used to introduce the postfix
   'nth parent' and 'peel onion' operation.
 
 . A colon `:` is used as in `srcref:dstref` to mean "use srcref\'s
   value and store it in dstref" in fetch and push operations.
   It may also be used to select a specific object such as with
-  'git-cat-file': "git cat-file blob v1.3.3:refs.c".
+  'git cat-file': "git cat-file blob v1.3.3:refs.c".
 
 . at-open-brace `@{` is used as a notation to access a reflog entry.
 
-With the `--branch` option, it expands a branch name shorthand and
-prints the name of the branch the shorthand refers to.
+With the `--branch` option, it expands the ``previous branch syntax''
+`@{-n}`.  For example, `@{-1}` is a way to refer the last branch you
+were on.  This option should be used by porcelains to accept this
+syntax anywhere a branch name is expected, so they can act as if you
+typed the branch name.
 
-EXAMPLE
+OPTIONS
 -------
+--[no-]allow-onelevel::
+	Controls whether one-level refnames are accepted (i.e.,
+	refnames that do not contain multiple `/`-separated
+	components).  The default is `--no-allow-onelevel`.
+
+--refspec-pattern::
+	Interpret <refname> as a reference name pattern for a refspec
+	(as used with remote repositories).  If this option is
+	enabled, <refname> is allowed to contain a single `*`
+	in place of a one full pathname component (e.g.,
+	`foo/*/bar` but not `foo/bar*`).
+
+--normalize::
+	Normalize 'refname' by removing any leading slash (`/`)
+	characters and collapsing runs of adjacent slashes between
+	name components into a single slash.  Iff the normalized
+	refname is valid then print it to standard output and exit
+	with a status of 0.  (`--print` is a deprecated way to spell
+	`--normalize`.)

-Detached HEAD
+DETACHED HEAD
 -------------
+HEAD normally refers to a named branch (e.g. 'master'). Meanwhile, each
+branch refers to a specific commit. Let's look at a repo with three
+commits, one of them tagged, and with branch 'master' checked out:
 
-It is sometimes useful to be able to 'checkout' a commit that is
-not at the tip of one of your branches.  The most obvious
-example is to check out the commit at a tagged official release
-point, like this:
+------------
+	   HEAD (refers to branch 'master')
+	    |
+	    v
+a---b---c  branch 'master' (refers to commit 'c')
+    ^
+    |
+  tag 'v2.0' (refers to commit 'b')
+------------
+
+When a commit is created in this state, the branch is updated to refer to
+the new commit. Specifically, 'git commit' creates a new commit 'd', whose
+parent is commit 'c', and then updates branch 'master' to refer to new
+commit 'd'. HEAD still refers to branch 'master' and so indirectly now refers
+to commit 'd':
 
 ------------
-$ git checkout v2.6.18
+$ edit; git add; git commit
+
+	       HEAD (refers to branch 'master')
+		|
+		v
+a---b---c---d  branch 'master' (refers to commit 'd')
+    ^
+    |
+  tag 'v2.0' (refers to commit 'b')
 ------------
 
-Earlier versions of git did not allow this and asked you to
-create a temporary branch using the `-b` option, but starting from
-version 1.5.0, the above command 'detaches' your HEAD from the
-current branch and directly points at the commit named by the tag
-(`v2.6.18` in the example above).
+It is sometimes useful to be able to checkout a commit that is not at
+the tip of any named branch, or even to create a new commit that is not
+referenced by a named branch. Let's look at what happens when we
+checkout commit 'b' (here we show two ways this may be done):
 
-You can use all git commands while in this state.  You can use
-`git reset --hard $othercommit` to further move around, for
-example.  You can make changes and create a new commit on top of
-a detached HEAD.  You can even create a merge by using `git
-merge $othercommit`.
+------------
+$ git checkout v2.0  # or
+$ git checkout master^^
+
+   HEAD (refers to commit 'b')
+    |
+    v
+a---b---c---d  branch 'master' (refers to commit 'd')
+    ^
+    |
+  tag 'v2.0' (refers to commit 'b')
+------------
 
-The state you are in while your HEAD is detached is not recorded
-by any branch (which is natural --- you are not on any branch).
-What this means is that you can discard your temporary commits
-and merges by switching back to an existing branch (e.g. `git
-checkout master`), and a later `git prune` or `git gc` would
-garbage-collect them.  If you did this by mistake, you can ask
-the reflog for HEAD where you were, e.g.
+Notice that regardless of which checkout command we use, HEAD now refers
+directly to commit 'b'. This is known as being in detached HEAD state.
+It means simply that HEAD refers to a specific commit, as opposed to
+referring to a named branch. Let's see what happens when we create a commit:
 
 ------------
-$ git log -g -2 HEAD
+$ edit; git add; git commit
+
+     HEAD (refers to commit 'e')
+      |
+      v
+      e
+     /
+a---b---c---d  branch 'master' (refers to commit 'd')
+    ^
+    |
+  tag 'v2.0' (refers to commit 'b')
 ------------
 
+There is now a new commit 'e', but it is referenced only by HEAD. We can
+of course add yet another commit in this state:
+
+------------
+$ edit; git add; git commit
+
+	 HEAD (refers to commit 'f')
+	  |
+	  v
+      e---f
+     /
+a---b---c---d  branch 'master' (refers to commit 'd')
+    ^
+    |
+  tag 'v2.0' (refers to commit 'b')
+------------
+
+In fact, we can perform all the normal Git operations. But, let's look
+at what happens when we then checkout master:
+
+------------
+$ git checkout master
+
+	       HEAD (refers to branch 'master')
+      e---f     |
+     /          v
+a---b---c---d  branch 'master' (refers to commit 'd')
+    ^
+    |
+  tag 'v2.0' (refers to commit 'b')
+------------
+
+It is important to realize that at this point nothing refers to commit
+'f'. Eventually commit 'f' (and by extension commit 'e') will be deleted
+by the routine Git garbage collection process, unless we create a reference
+before that happens. If we have not yet moved away from commit 'f',
+any of these will create a reference to it:
+
+------------
+$ git checkout -b foo   <1>
+$ git branch foo        <2>
+$ git tag foo           <3>
+------------
+
+<1> creates a new branch 'foo', which refers to commit 'f', and then
+updates HEAD to refer to branch 'foo'. In other words, we'll no longer
+be in detached HEAD state after this command.
+
+<2> similarly creates a new branch 'foo', which refers to commit 'f',
+but leaves HEAD detached.
+
+<3> creates a new tag 'foo', which refers to commit 'f',
+leaving HEAD detached.
+
+If we have moved away from commit 'f', then we must first recover its object
+name (typically by using git reflog), and then we can create a reference to
+it. For example, to see the last two commits to which HEAD referred, we
+can use either of these commands:
+
+------------
+$ git reflog -2 HEAD # or
+$ git log -g -2 HEAD

 DESCRIPTION
 -----------
-Given one existing commit, apply the change the patch introduces, and record a
-new commit that records it.  This requires your working tree to be clean (no
-modifications from the HEAD commit).
+
+Given one or more existing commits, apply the change each one
+introduces, recording a new commit for each.  This requires your
+working tree to be clean (no modifications from the HEAD commit).
+
+When it is not obvious how to apply a change, the following
+happens:
+
+1. The current branch and `HEAD` pointer stay at the last commit
+   successfully made.
+2. The `CHERRY_PICK_HEAD` ref is set to point at the commit that
+   introduced the change that is difficult to apply.
+3. Paths in which the change applied cleanly are updated both
+   in the index file and in your working tree.
+4. For conflicting paths, the index file records up to three
+   versions, as described in the "TRUE MERGE" section of
+   linkgit:git-merge[1].  The working tree files will include
+   a description of the conflict bracketed by the usual
+   conflict markers `<<<<<<<` and `>>>>>>>`.
+5. No other modifications are made.
+
+See linkgit:git-merge[1] for some hints on resolving such
+conflicts.

 SYNOPSIS
 --------
+[verse]
 'git cherry' [-v] [<upstream> [<head> [<limit>]]]
 
 DESCRIPTION
 -----------
-The changeset (or "diff") of each commit between the fork-point and <head>
-is compared against each commit between the fork-point and <upstream>.
-The commits are compared with their 'patch id', obtained from
-the 'git-patch-id' program.
+Determine whether there are commits in `<head>..<upstream>` that are
+equivalent to those in the range `<limit>..<head>`.
 
-Every commit that doesn't exist in the <upstream> branch
-has its id (sha1) reported, prefixed by a symbol.  The ones that have
-equivalent change already
-in the <upstream> branch are prefixed with a minus (-) sign, and those
-that only exist in the <head> branch are prefixed with a plus (+) symbol:
-
-               __*__*__*__*__> <upstream>
-              /
-    fork-point
-              \__+__+__-__+__+__-__+__> <head>
-
-
-If a <limit> has been given then the commits along the <head> branch up
-to and including <limit> are not reported:
-
-               __*__*__*__*__> <upstream>
-              /
-    fork-point
-              \__*__*__<limit>__-__+__> <head>
-
-
-Because 'git-cherry' compares the changeset rather than the commit id
-(sha1), you can use 'git-cherry' to find out if a commit you made locally
-has been applied <upstream> under a different commit id.  For example,
-this will happen if you're feeding patches <upstream> via email rather
-than pushing or pulling commits directly.
+The equivalence test is based on the diff, after removing whitespace
+and line numbers.  git-cherry therefore detects when commits have been
+"copied" by means of linkgit:git-cherry-pick[1], linkgit:git-am[1] or
+linkgit:git-rebase[1].
 
+Outputs the SHA1 of every commit in `<limit>..<head>`, prefixed with
+`-` for commits that have an equivalent in <upstream>, and `+` for
+commits that do not.

+Patch workflows
+~~~~~~~~~~~~~~~
+
+git-cherry is frequently used in patch-based workflows (see
+linkgit:gitworkflows[7]) to determine if a series of patches has been
+applied by the upstream maintainer.  In such a workflow you might
+create and send a topic branch like this:
+
+------------
+$ git checkout -b topic origin/master
+# work and create some commits
+$ git format-patch origin/master
+$ git send-email ... 00*
+------------
+
+Later, you can see whether your changes have been applied by saying
+(still on `topic`):
+
+------------
+$ git fetch  # update your notion of origin/master
+$ git cherry -v
+------------
+
+Concrete example
+~~~~~~~~~~~~~~~~
+
+In a situation where topic consisted of three commits, and the
+maintainer applied two of them, the situation might look like:
+
+------------
+$ git log --graph --oneline --decorate --boundary origin/master...topic
+* 7654321 (origin/master) upstream tip commit
+[... snip some other commits ...]
+* cccc111 cherry-pick of C
+* aaaa111 cherry-pick of A
+[... snip a lot more that has happened ...]
+| * cccc000 (topic) commit C
+| * bbbb000 commit B
+| * aaaa000 commit A
+|/
+o 1234567 branch point
+------------
+
+In such cases, git-cherry shows a concise summary of what has yet to
+be applied:
+
+------------
+$ git cherry origin/master topic
+- cccc000... commit C
++ bbbb000... commit B
+- aaaa000... commit A
+------------
+
+Here, we see that the commits A and C (marked with `-`) can be
+dropped from your `topic` branch when you rebase it on top of
+`origin/master`, while the commit B (marked with `+`) still needs to
+be kept so that it will be sent to be applied to `origin/master`.
+
+
+Using a limit
+~~~~~~~~~~~~~
+
+The optional <limit> is useful in cases where your topic is based on
+other work that is not in upstream.  Expanding on the previous
+example, this might look like:
+

+NAME

+git-credential-cache - Helper to temporarily store passwords in memory
+
+SYNOPSIS
+--------
+-----------------------------
+git config credential.helper 'cache [options]'
+-----------------------------
+
+DESCRIPTION
+-----------
+
+This command caches credentials in memory for use by future Git
+programs. The stored credentials never touch the disk, and are forgotten
+after a configurable timeout.  The cache is accessible over a Unix
+domain socket, restricted to the current user by filesystem permissions.
+
+You probably don't want to invoke this command directly; it is meant to
+be used as a credential helper by other parts of Git. See
+linkgit:gitcredentials[7] or `EXAMPLES` below.
+
+OPTIONS
+-------
+
+--timeout <seconds>::
+
+	Number of seconds to cache credentials (default: 900).
+
+--socket <path>::
+
+	Use `<path>` to contact a running cache daemon (or start a new
+	cache daemon if one is not started). Defaults to
+	`~/.git-credential-cache/socket`. If your home directory is on a
+	network-mounted filesystem, you may need to change this to a
+	local filesystem.
+
+CONTROLLING THE DAEMON
+----------------------
+
+If you would like the daemon to exit early, forgetting all cached
+credentials before their timeout, you can issue an `exit` action:
+
+--------------------------------------
+git credential-cache exit
+--------------------------------------
+
+EXAMPLES
+--------
+
+The point of this helper is to reduce the number of times you must type
+your username or password. For example:
+
+------------------------------------
+$ git config credential.helper cache
+$ git push http://example.com/repo.git
+Username: <type your username>
+Password: <type your password>
+
+[work for 5 more minutes]
+$ git push http://example.com/repo.git
+[your credentials are used automatically]
+------------------------------------
+
+You can provide options via the credential.helper configuration
+variable (this example drops the cache time to 5 minutes):
+
+-------------------------------------------------------
+$ git config credential.helper 'cache --timeout=300'

+NAME
+----
+git-credential-store - Helper to store credentials on disk
+
+SYNOPSIS
+--------
+-------------------
+git config credential.helper 'store [options]'
+-------------------
+
+DESCRIPTION
+-----------
+
+NOTE: Using this helper will store your passwords unencrypted on disk,
+protected only by filesystem permissions. If this is not an acceptable
+security tradeoff, try linkgit:git-credential-cache[1], or find a helper
+that integrates with secure storage provided by your operating system.
+
+This command stores credentials indefinitely on disk for use by future
+Git programs.
+
+You probably don't want to invoke this command directly; it is meant to
+be used as a credential helper by other parts of git. See
+linkgit:gitcredentials[7] or `EXAMPLES` below.
+
+OPTIONS
+-------
+
+--file=<path>::
+
+	Use `<path>` to store credentials. The file will have its
+	filesystem permissions set to prevent other users on the system
+	from reading it, but will not be encrypted or otherwise
+	protected. Defaults to `~/.git-credentials`.
+
+EXAMPLES
+--------
+
+The point of this helper is to reduce the number of times you must type
+your username or password. For example:
+
+------------------------------------------
+$ git config credential.helper store
+$ git push http://example.com/repo.git
+Username: <type your username>
+Password: <type your password>
+
+[several days later]
+$ git push http://example.com/repo.git
+[your credentials are used automatically]
+------------------------------------------
+
+STORAGE FORMAT
+--------------
+
+The `.git-credentials` file is stored in plaintext. Each credential is
+stored on its own line as a URL like:
+
+------------------------------
+https://user:pass@example.com
+------------------------------
+
+When Git needs authentication for a particular URL context,
+credential-store will consider that context a pattern to match against
+each entry in the credentials file.  If the protocol, hostname, and
+username (if we already have one) match, then the password is returned
+to Git. See the discussion of configuration in linkgit:gitcredentials[7]
+for more information.

+=================
+
+NAME
+----
+git-credential - Retrieve and store user credentials
+
+SYNOPSIS
+--------
+------------------
+git credential <fill|approve|reject>
+------------------
+
+DESCRIPTION
+-----------
+
+Git has an internal interface for storing and retrieving credentials
+from system-specific helpers, as well as prompting the user for
+usernames and passwords. The git-credential command exposes this
+interface to scripts which may want to retrieve, store, or prompt for
+credentials in the same manner as Git. The design of this scriptable
+interface models the internal C API; see
+link:technical/api-credentials.html[the Git credential API] for more
+background on the concepts.
+
+git-credential takes an "action" option on the command-line (one of
+`fill`, `approve`, or `reject`) and reads a credential description
+on stdin (see <<IOFMT,INPUT/OUTPUT FORMAT>>).
+
+If the action is `fill`, git-credential will attempt to add "username"
+and "password" attributes to the description by reading config files,
+by contacting any configured credential helpers, or by prompting the
+user. The username and password attributes of the credential
+description are then printed to stdout together with the attributes
+already provided.
+
+If the action is `approve`, git-credential will send the description
+to any configured credential helpers, which may store the credential
+for later use.
+
+If the action is `reject`, git-credential will send the description to
+any configured credential helpers, which may erase any stored
+credential matching the description.
+
+If the action is `approve` or `reject`, no output should be emitted.
+
+TYPICAL USE OF GIT CREDENTIAL
+-----------------------------
+
+An application using git-credential will typically use `git
+credential` following these steps:
+
+  1. Generate a credential description based on the context.
++
+For example, if we want a password for
+`https://example.com/foo.git`, we might generate the following
+credential description (don't forget the blank line at the end; it
+tells `git credential` that the application finished feeding all the
+information it has):
+
+	 protocol=https
+	 host=example.com
+	 path=foo.git
+
+  2. Ask git-credential to give us a username and password for this
+     description. This is done by running `git credential fill`,
+     feeding the description from step (1) to its standard input. The complete
+     credential description (including the credential per se, i.e. the
+     login and password) will be produced on standard output, like:
+
+	protocol=https
+	host=example.com
+	username=bob
+	password=secr3t
++
+In most cases, this means the attributes given in the input will be
+repeated in the output, but Git may also modify the credential
+description, for example by removing the `path` attribute when the
+protocol is HTTP(s) and `credential.useHttpPath` is false.
++
+If the `git credential` knew about the password, this step may
+not have involved the user actually typing this password (the
+user may have typed a password to unlock the keychain instead,
+or no user interaction was done if the keychain was already
+unlocked) before it returned `password=secr3t`.
+
+  3. Use the credential (e.g., access the URL with the username and
+     password from step (2)), and see if it's accepted.
+
+  4. Report on the success or failure of the password. If the
+     credential allowed the operation to complete successfully, then
+     it can be marked with an "approve" action to tell `git
+     credential` to reuse it in its next invocation. If the credential
+     was rejected during the operation, use the "reject" action so
+     that `git credential` will ask for a new password in its next
+     invocation. In either case, `git credential` should be fed with
+     the credential description obtained from step (2) (which also
+     contain the ones provided in step (1)).
+
+[[IOFMT]]
+INPUT/OUTPUT FORMAT
+-------------------
+
+`git credential` reads and/or writes (depending on the action used)
+credential information in its standard input/output. This information
+can correspond either to keys for which `git credential` will obtain
+the login/password information (e.g. host, protocol, path), or to the
+actual credential data to be obtained (login/password).
+
+The credential is split into a set of named attributes, with one
+attribute per line. Each attribute is
+specified by a key-value pair, separated by an `=` (equals) sign,
+followed by a newline. The key may contain any bytes except `=`,
+newline, or NUL. The value may contain any bytes except newline or NUL.
+In both cases, all bytes are treated as-is (i.e., there is no quoting,
+and one cannot transmit a value with newline or NUL in it). The list of
+attributes is terminated by a blank line or end-of-file.
+Git understands the following attributes:
+
+`protocol`::
+
+	The protocol over which the credential will be used (e.g.,
+	`https`).
+
+`host`::
+
+	The remote hostname for a network credential.
+
+`path`::
+
+	The path with which the credential will be used. E.g., for
+	accessing a remote https repository, this will be the
+	repository's path on the server.
+
+`username`::
+
+	The credential's username, if we already have one (e.g., from a
+	URL, from the user, or from a previously run helper).
+
+`password`::
+
+	The credential's password, if we are asking it to be stored.
+
+`url`::
+
+	When this special attribute is read by `git credential`, the
+	value is parsed as a URL and treated as if its constituent parts
+	were read (e.g., `url=https://example.com` would behave as if
+	`protocol=https` and `host=example.com` had been provided). This
+	can help callers avoid parsing URLs themselves.  Note that any
+	components which are missing from the URL (e.g., there is no
+	username in the example above) will be set to empty; if you want
+	to provide a URL and override some attributes, provide the URL
+	attribute first, followed by any overrides.

@@ -304,6 +359,43 @@ Operations supported
 
 All the operations required for normal use are supported, including
 checkout, diff, status, update, log, add, remove, commit.
+
+Most CVS command arguments that read CVS tags or revision numbers
+(typically -r) work, and also support any git refspec
+(tag, branch, commit ID, etc).
+However, CVS revision numbers for non-default branches are not well
+emulated, and cvs log does not show tags or branches at
+all.  (Non-main-branch CVS revision numbers superficially resemble CVS
+revision numbers, but they actually encode a git commit ID directly,
+rather than represent the number of revisions since the branch point.)
+
+Note that there are two ways to checkout a particular branch.
+As described elsewhere on this page, the "module" parameter
+of cvs checkout is interpreted as a branch name, and it becomes
+the main branch.  It remains the main branch for a given sandbox
+even if you temporarily make another branch sticky with
+cvs update -r.  Alternatively, the -r argument can indicate
+some other branch to actually checkout, even though the module
+is still the "main" branch.  Tradeoffs (as currently
+implemented): Each new "module" creates a new database on disk with
+a history for the given module, and after the database is created,
+operations against that main branch are fast.  Or alternatively,
+-r doesn't take any extra disk space, but may be significantly slower for
+many operations, like cvs update.
+
+If you want to refer to a git refspec that has characters that are
+not allowed by CVS, you have two options.  First, it may just work
+to supply the git refspec directly to the appropriate CVS -r argument;
+some CVS clients don't seem to do much sanity checking of the argument.
+Second, if that fails, you can use a special character escape mechanism
+that only uses characters that are valid in CVS tags.  A sequence
+of 4 or 5 characters of the form (underscore (`"_"`), dash (`"-"`),
+one or two characters, and dash (`"-"`)) can encode various characters based
+on the one or two letters: `"s"` for slash (`"/"`), `"p"` for
+period (`"."`), `"u"` for underscore (`"_"`), or two hexadecimal digits
+for any byte value at all (typically an ASCII number, or perhaps a part
+of a UTF-8 encoded character).
+
 Legacy monitoring operations are not supported (edit, watch and related).
 Exports and tagging (tags and branches) are not supported at this stage.

 -----------
 
-Since 'git-fast-import' cannot tag trees, you will not be
-able to export the linux-2.6.git repository completely, as it contains
-a tag referencing a tree instead of a commit.
+If the `--anonymize` option is given, git will attempt to remove all
+identifying information from the repository while still retaining enough
+of the original tree and history patterns to reproduce some bugs. The
+goal is that a git bug which is found on a private repository will
+persist in the anonymized repository, and the latter can be shared with
+git developers to help solve the bug.
+
+With this option, git will replace all refnames, paths, blob contents,
+commit and tag messages, names, and email addresses in the output with
+anonymized data.  Two instances of the same string will be replaced
+equivalently (e.g., two commits with the same author will have the same
+anonymized author in the output, but bear no resemblance to the original
+author string). The relationship between commits, branches, and tags is
+retained, as well as the commit timestamps (but the commit messages and
+refnames bear no resemblance to the originals). The relative makeup of
+the tree is retained (e.g., if you have a root tree with 10 files and 3
+trees, so will the output), but their names and the contents of the
+files will be replaced.
+
+If you think you have found a git bug, you can start by exporting an
+anonymized stream of the whole repository:
+
+---------------------------------------------------
+$ git fast-export --anonymize --all >anon-stream
+---------------------------------------------------
+
+Then confirm that the bug persists in a repository created from that
+stream (many bugs will not, as they really do depend on the exact
+repository contents):
+
+---------------------------------------------------
+$ git init anon-repo
+$ cd anon-repo
+$ git fast-import <../anon-stream
+$ ... test your bug ...
+---------------------------------------------------
+
+If the anonymized repository shows the bug, it may be worth sharing
+`anon-stream` along with a regular bug report. Note that the anonymized
+stream compresses very well, so gzipping it is encouraged. If you want
+to examine the stream to see that it does not contain any private data,
+you can peruse it directly before sending. You may also want to try:
+
+---------------------------------------------------
+$ perl -pe 's/\d+/X/g' <anon-stream | sort -u | less
+---------------------------------------------------
+
+which shows all of the unique lines (with numbers converted to "X", to
+collapse "User 0", "User 1", etc into "User X"). This produces a much
+smaller output, and it is usually easy to quickly confirm that there is
+no private data in the stream.

+Responses To Commands
+---------------------
+New objects written by fast-import are not available immediately.
+Most fast-import commands have no visible effect until the next
+checkpoint (or completion).  The frontend can send commands to
+fill fast-import's input pipe without worrying about how quickly
+they will take effect, which improves performance by simplifying
+scheduling.
+
+For some frontends, though, it is useful to be able to read back
+data from the current repository as it is being updated (for
+example when the source material describes objects in terms of
+patches to be applied to previously imported objects).  This can
+be accomplished by connecting the frontend and fast-import via
+bidirectional pipes:
+
+====
+	mkfifo fast-import-output
+	frontend <fast-import-output |
+	git fast-import >fast-import-output
+====
+
+A frontend set up this way can use `progress`, `ls`, and `cat-blob`
+commands to read information from the import in progress.
+
+To avoid deadlock, such frontends must completely consume any
+pending output from `progress`, `ls`, and `cat-blob` before
+performing writes to fast-import that might block.

 DESCRIPTION
 -----------
-Fetches named heads or tags from another repository, along with
-the objects necessary to complete them.
-
-The ref names and their object names of fetched refs are stored
-in `.git/FETCH_HEAD`.  This information is left for a later merge
-operation done by 'git-merge'.
-
-When <refspec> stores the fetched result in tracking branches,
-the tags that point at these branches are automatically
-followed.  This is done by first fetching from the remote using
-the given <refspec>s, and if the repository has objects that are
-pointed by remote tags that it does not yet have, then fetch
-those missing tags.  If the other end has tags that point at
-branches you are not interested in, you will not get them.
-
+Fetch branches and/or tags (collectively, "refs") from one or more
+other repositories, along with the objects necessary to complete their
+histories.  Remote-tracking branches are updated (see the description
+of <refspec> below for ways to control this behavior).
+
+By default, any tag that points into the histories being fetched is
+also fetched; the effect is to fetch tags that
+point at branches that you are interested in.  This default behavior
+can be changed by using the --tags or --no-tags options or by
+configuring remote.<name>.tagopt.  By using a refspec that fetches tags
+explicitly, you can fetch tags that do not point into branches you
+are interested in as well.
+
+'git fetch' can fetch from either a single named repository or URL,
+or from several repositories at once if <group> is given and
+there is a remotes.<group> entry in the configuration file.
+(See linkgit:git-config[1]).
+
+When no remote is specified, by default the `origin` remote will be used,
+unless there's an upstream branch configured for the current branch.
+
+The names of refs that are fetched, together with the object names
+they point at, are written to `.git/FETCH_HEAD`.  This information
+may be used by scripts or other git commands, such as linkgit:git-pull[1].

+CONFIGURED REMOTE-TRACKING BRANCHES[[CRTB]]
+-------------------------------------------
+
+You often interact with the same remote repository by
+regularly and repeatedly fetching from it.  In order to keep track
+of the progress of such a remote repository, `git fetch` allows you
+to configure `remote.<repository>.fetch` configuration variables.
+
+Typically such a variable may look like this:
+
+------------------------------------------------
+[remote "origin"]
+	fetch = +refs/heads/*:refs/remotes/origin/*
+------------------------------------------------
+
+This configuration is used in two ways:
+
+* When `git fetch` is run without specifying what branches
+  and/or tags to fetch on the command line, e.g. `git fetch origin`
+  or `git fetch`, `remote.<repository>.fetch` values are used as
+  the refspecs---they specify which refs to fetch and which local refs
+  to update.  The example above will fetch
+  all branches that exist in the `origin` (i.e. any ref that matches
+  the left-hand side of the value, `refs/heads/*`) and update the
+  corresponding remote-tracking branches in the `refs/remotes/origin/*`
+  hierarchy.
+
+* When `git fetch` is run with explicit branches and/or tags
+  to fetch on the command line, e.g. `git fetch origin master`, the
+  <refspec>s given on the command line determine what are to be
+  fetched (e.g. `master` in the example,
+  which is a short-hand for `master:`, which in turn means
+  "fetch the 'master' branch but I do not explicitly say what
+  remote-tracking branch to update with it from the command line"),
+  and the example command will
+  fetch _only_ the 'master' branch.  The `remote.<repository>.fetch`
+  values determine which
+  remote-tracking branch, if any, is updated.  When used in this
+  way, the `remote.<repository>.fetch` values do not have any
+  effect in deciding _what_ gets fetched (i.e. the values are not
+  used as refspecs when the command-line lists refspecs); they are
+  only used to decide _where_ the refs that are fetched are stored
+  by acting as a mapping.
+
+The latter use of the `remote.<repository>.fetch` values can be
+overridden by giving the `--refmap=<refspec>` parameter(s) on the
+command line.

+EXAMPLES

+* Update the remote-tracking branches:
++
+------------------------------------------------
+$ git fetch origin
+------------------------------------------------
++
+The above command copies all branches from the remote refs/heads/
+namespace and stores them to the local refs/remotes/origin/ namespace,
+unless the branch.<name>.fetch option is used to specify a non-default
+refspec.
+
+* Using refspecs explicitly:
++
+------------------------------------------------
+$ git fetch origin +pu:pu maint:tmp
+------------------------------------------------
++
+This updates (or creates, as necessary) branches `pu` and `tmp` in
+the local repository by fetching from the branches (respectively)
+`pu` and `maint` from the remote repository.
++
+The `pu` branch will be updated even if it is does not fast-forward,
+because it is prefixed with a plus sign; `tmp` will not be.
+
+* Peek at a remote's branch, without configuring the remote in your local
+repository:
++
+------------------------------------------------
+$ git fetch git://git.kernel.org/pub/scm/git/git.git maint
+$ git log FETCH_HEAD
+------------------------------------------------
++
+The first command fetches the `maint` branch from the repository at
+`git://git.kernel.org/pub/scm/git/git.git` and the second command uses
+`FETCH_HEAD` to examine the branch with linkgit:git-log[1].  The fetched
+objects will eventually be removed by git's built-in housekeeping (see
+linkgit:git-gc[1]).
+
+BUGS
+----
+Using --recurse-submodules can only fetch new commits in already checked
+out submodules right now. When e.g. upstream added a new submodule in the
+just fetched commits of the superproject the submodule itself can not be
+fetched, making it impossible to check out that submodule later without
+having to do a fetch again. This is expected to be fixed in a future Git
+version.

+Notes
+-----
+
+git-filter-branch allows you to make complex shell-scripted rewrites
+of your Git history, but you probably don't need this flexibility if
+you're simply _removing unwanted data_ like large files or passwords.
+For those operations you may want to consider
+http://rtyley.github.io/bfg-repo-cleaner/[The BFG Repo-Cleaner],
+a JVM-based alternative to git-filter-branch, typically at least
+10-50x faster for those use-cases, and with quite different
+characteristics:
+
+* Any particular version of a file is cleaned exactly _once_. The BFG,
+  unlike git-filter-branch, does not give you the opportunity to
+  handle a file differently based on where or when it was committed
+  within your history. This constraint gives the core performance
+  benefit of The BFG, and is well-suited to the task of cleansing bad
+  data - you don't care _where_ the bad data is, you just want it
+  _gone_.
+
+* By default The BFG takes full advantage of multi-core machines,
+  cleansing commit file-trees in parallel. git-filter-branch cleans
+  commits sequentially (i.e. in a single-threaded manner), though it
+  _is_ possible to write filters that include their own parallelism,
+  in the scripts executed against each commit.
+
+* The http://rtyley.github.io/bfg-repo-cleaner/#examples[command options]
+  are much more restrictive than git-filter branch, and dedicated just
+  to the tasks of removing unwanted data- e.g:
+  `--strip-blobs-bigger-than 1M`.

+
+Checking for patch corruption
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Many mailers if not set up properly will corrupt whitespace.  Here are
+two common types of corruption:
+
+* Empty context lines that do not have _any_ whitespace.
+
+* Non-empty context lines that have one extra whitespace at the
+  beginning.
+
+One way to test if your MUA is set up correctly is:
+
+* Send the patch to yourself, exactly the way you would, except
+  with To: and Cc: lines that do not contain the list and
+  maintainer address.
+
+* Save that patch to a file in UNIX mailbox format.  Call it a.patch,
+  say.
+
+* Apply it:
+
+    $ git fetch <project> master:test-apply
+    $ git checkout test-apply
+    $ git reset --hard
+    $ git am a.patch
+
+If it does not apply correctly, there can be various reasons.
+
+* The patch itself does not apply cleanly.  That is _bad_ but
+  does not have much to do with your MUA.  You might want to rebase
+  the patch with linkgit:git-rebase[1] before regenerating it in
+  this case.
+
+* The MUA corrupted your patch; "am" would complain that
+  the patch does not apply.  Look in the .git/rebase-apply/ subdirectory and
+  see what 'patch' file contains and check for the common
+  corruption patterns mentioned above.
+
+* While at it, check the 'info' and 'final-commit' files as well.
+  If what is in 'final-commit' is not exactly what you would want to
+  see in the commit log message, it is very likely that the
+  receiver would end up hand editing the log message when applying
+  your patch.  Things like "Hi, this is my first patch.\n" in the
+  patch e-mail should come after the three-dash line that signals
+  the end of the commit message.
+
+MUA-SPECIFIC HINTS
+------------------
+Here are some hints on how to successfully submit patches inline using
+various mailers.
+
+GMail
+~~~~~
+GMail does not have any way to turn off line wrapping in the web
+interface, so it will mangle any emails that you send.  You can however
+use "git send-email" and send your patches through the GMail SMTP server, or
+use any IMAP email client to connect to the google IMAP server and forward
+the emails through that.
+
+For hints on using 'git send-email' to send your patches through the
+GMail SMTP server, see the EXAMPLE section of linkgit:git-send-email[1].
+
+For hints on submission using the IMAP interface, see the EXAMPLE
+section of linkgit:git-imap-send[1].
+
+Thunderbird
+~~~~~~~~~~~
+By default, Thunderbird will both wrap emails as well as flag
+them as being 'format=flowed', both of which will make the
+resulting email unusable by Git.
+
+There are three different approaches: use an add-on to turn off line wraps,
+configure Thunderbird to not mangle patches, or use
+an external editor to keep Thunderbird from mangling the patches.
+
+Approach #1 (add-on)
+^^^^^^^^^^^^^^^^^^^^
+
+Install the Toggle Word Wrap add-on that is available from
+https://addons.mozilla.org/thunderbird/addon/toggle-word-wrap/
+It adds a menu entry "Enable Word Wrap" in the composer's "Options" menu
+that you can tick off. Now you can compose the message as you otherwise do
+(cut + paste, 'git format-patch' | 'git imap-send', etc), but you have to
+insert line breaks manually in any text that you type.
+
+Approach #2 (configuration)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Three steps:
+
+1. Configure your mail server composition as plain text:
+   Edit...Account Settings...Composition & Addressing,
+   uncheck "Compose Messages in HTML".
+
+2. Configure your general composition window to not wrap.
++
+In Thunderbird 2:
+Edit..Preferences..Composition, wrap plain text messages at 0
++
+In Thunderbird 3:
+Edit..Preferences..Advanced..Config Editor.  Search for
+"mail.wrap_long_lines".
+Toggle it to make sure it is set to `false`. Also, search for
+"mailnews.wraplength" and set the value to 0.
+
+3. Disable the use of format=flowed:
+Edit..Preferences..Advanced..Config Editor.  Search for
+"mailnews.send_plaintext_flowed".
+Toggle it to make sure it is set to `false`.
+
+After that is done, you should be able to compose email as you
+otherwise would (cut + paste, 'git format-patch' | 'git imap-send', etc),
+and the patches will not be mangled.
+
+Approach #3 (external editor)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The following Thunderbird extensions are needed:
+AboutConfig from http://aboutconfig.mozdev.org/ and
+External Editor from http://globs.org/articles.php?lng=en&pg=8
+
+1. Prepare the patch as a text file using your method of choice.
+
+2. Before opening a compose window, use Edit->Account Settings to
+   uncheck the "Compose messages in HTML format" setting in the
+   "Composition & Addressing" panel of the account to be used to
+   send the patch.
+
+3. In the main Thunderbird window, 'before' you open the compose
+   window for the patch, use Tools->about:config to set the
+   following to the indicated values:
++
+----------
+	mailnews.send_plaintext_flowed  => false
+	mailnews.wraplength             => 0
+----------
+
+4. Open a compose window and click the external editor icon.
+
+5. In the external editor window, read in the patch file and exit
+   the editor normally.
+
+Side note: it may be possible to do step 2 with
+about:config and the following settings but no one's tried yet.
+
+----------
+	mail.html_compose                       => false
+	mail.identity.default.compose_html      => false
+	mail.identity.id?.compose_html          => false
+----------
+
+There is a script in contrib/thunderbird-patch-inline which can help
+you include patches with Thunderbird in an easy way. To use it, do the
+steps above and then use the script as the external editor.
+
+KMail
+~~~~~
+This should help you to submit patches inline using KMail.
+
+1. Prepare the patch as a text file.
+
+2. Click on New Mail.
+
+3. Go under "Options" in the Composer window and be sure that
+   "Word wrap" is not set.
+
+4. Use Message -> Insert file... and insert the patch.
+
+5. Back in the compose window: add whatever other text you wish to the
+   message, complete the addressing and subject fields, and press send.
+

+DESCRIPTION
+-----------
+
+This command creates an empty Git repository - basically a `.git`
+directory with subdirectories for `objects`, `refs/heads`,
+`refs/tags`, and template files.  An initial `HEAD` file that
+references the HEAD of the master branch is also created.
+
+If the `$GIT_DIR` environment variable is set then it specifies a path
+to use instead of `./.git` for the base of the repository.
+
+If the object storage directory is specified via the
+`$GIT_OBJECT_DIRECTORY` environment variable then the sha1 directories
+are created underneath - otherwise the default `$GIT_DIR/objects`
+directory is used.
+
+Running 'git init' in an existing repository is safe. It will not
+overwrite things that are already there. The primary reason for
+rerunning 'git init' is to pick up newly added templates (or to move
+the repository to another place if --separate-git-dir is given).

+TEMPLATE DIRECTORY
+------------------
 
-DESCRIPTION
------------
-This command creates an empty git repository - basically a `.git` directory
-with subdirectories for `objects`, `refs/heads`, `refs/tags`, and
-template files.
-An initial `HEAD` file that references the HEAD of the master branch
-is also created.
+The template directory contains files and directories that will be copied to
+the `$GIT_DIR` after it is created.
 
-If the `$GIT_DIR` environment variable is set then it specifies a path
-to use instead of `./.git` for the base of the repository.
+The template directory will be one of the following (in order):
+
+ - the argument given with the `--template` option;
 
-If the object storage directory is specified via the `$GIT_OBJECT_DIRECTORY`
-environment variable then the sha1 directories are created underneath -
-otherwise the default `$GIT_DIR/objects` directory is used.
+ - the contents of the `$GIT_TEMPLATE_DIR` environment variable;
 
-Running 'git-init' in an existing repository is safe. It will not overwrite
-things that are already there. The primary reason for rerunning 'git-init'
-is to pick up newly added templates.
+ - the `init.templatedir` configuration variable; or
 
-Note that 'git-init' is the same as 'git-init-db'.  The command
-was primarily meant to initialize the object database, but over
-time it has become responsible for setting up the other aspects
-of the repository, such as installing the default hooks and
-setting the configuration variables.  The old name is retained
-for backward compatibility reasons.
+ - the default template directory: `/usr/share/git-core/templates`.
 
+The default template directory includes some directory structure, suggested
+"exclude patterns" (see linkgit:gitignore[5]), and sample hook files (see linkgit:githooks[5]).

+NAME
+----
+git-interpret-trailers - help add structured information into commit messages
+
+SYNOPSIS
+--------
+[verse]
+'git interpret-trailers' [--trim-empty] [(--trailer <token>[(=|:)<value>])...] [<file>...]
+
+DESCRIPTION
+-----------
+Help adding 'trailers' lines, that look similar to RFC 822 e-mail
+headers, at the end of the otherwise free-form part of a commit
+message.
+
+This command reads some patches or commit messages from either the
+<file> arguments or the standard input if no <file> is specified. Then
+this command applies the arguments passed using the `--trailer`
+option, if any, to the commit message part of each input file. The
+result is emitted on the standard output.
+
+Some configuration variables control the way the `--trailer` arguments
+are applied to each commit message and the way any existing trailer in
+the commit message is changed. They also make it possible to
+automatically add some trailers.
+
+By default, a '<token>=<value>' or '<token>:<value>' argument given
+using `--trailer` will be appended after the existing trailers only if
+the last trailer has a different (<token>, <value>) pair (or if there
+is no existing trailer). The <token> and <value> parts will be trimmed
+to remove starting and trailing whitespace, and the resulting trimmed
+<token> and <value> will appear in the message like this:
+
+------------------------------------------------
+token: value
+------------------------------------------------
+
+This means that the trimmed <token> and <value> will be separated by
+`': '` (one colon followed by one space).
+
+By default the new trailer will appear at the end of all the existing
+trailers. If there is no existing trailer, the new trailer will appear
+after the commit message part of the output, and, if there is no line
+with only spaces at the end of the commit message part, one blank line
+will be added before the new trailer.
+
+Existing trailers are extracted from the input message by looking for
+a group of one or more lines that contain a colon (by default), where
+the group is preceded by one or more empty (or whitespace-only) lines.
+The group must either be at the end of the message or be the last
+non-whitespace lines before a line that starts with '---'. Such three
+minus signs start the patch part of the message.
+
+When reading trailers, there can be whitespaces before and after the
+token, the separator and the value. There can also be whitespaces
+inside the token and the value.
+
+Note that 'trailers' do not follow and are not intended to follow many
+rules for RFC 822 headers. For example they do not follow the line
+folding rules, the encoding rules and probably many other rules.
+
+OPTIONS
+-------
+--trim-empty::
+	If the <value> part of any trailer contains only whitespace,
+	the whole trailer will be removed from the resulting message.
+	This apply to existing trailers as well as new trailers.
+
+--trailer <token>[(=|:)<value>]::
+	Specify a (<token>, <value>) pair that should be applied as a
+	trailer to the input messages. See the description of this
+	command.
+
+CONFIGURATION VARIABLES
+-----------------------
+
+trailer.separators::
+	This option tells which characters are recognized as trailer
+	separators. By default only ':' is recognized as a trailer
+	separator, except that '=' is always accepted on the command
+	line for compatibility with other git commands.
++
+The first character given by this option will be the default character
+used when another separator is not specified in the config for this
+trailer.
++
+For example, if the value for this option is "%=$", then only lines
+using the format '<token><sep><value>' with <sep> containing '%', '='
+or '$' and then spaces will be considered trailers. And '%' will be
+the default separator used, so by default trailers will appear like:
+'<token>% <value>' (one percent sign and one space will appear between
+the token and the value).
+
+trailer.where::
+	This option tells where a new trailer will be added.
++
+This can be `end`, which is the default, `start`, `after` or `before`.
++
+If it is `end`, then each new trailer will appear at the end of the
+existing trailers.
++
+If it is `start`, then each new trailer will appear at the start,
+instead of the end, of the existing trailers.
++
+If it is `after`, then each new trailer will appear just after the
+last trailer with the same <token>.
++
+If it is `before`, then each new trailer will appear just before the
+first trailer with the same <token>.
+
+trailer.ifexists::
+	This option makes it possible to choose what action will be
+	performed when there is already at least one trailer with the
+	same <token> in the message.
++
+The valid values for this option are: `addIfDifferentNeighbor` (this
+is the default), `addIfDifferent`, `add`, `overwrite` or `doNothing`.
++
+With `addIfDifferentNeighbor`, a new trailer will be added only if no
+trailer with the same (<token>, <value>) pair is above or below the line
+where the new trailer will be added.
++
+With `addIfDifferent`, a new trailer will be added only if no trailer
+with the same (<token>, <value>) pair is already in the message.
++
+With `add`, a new trailer will be added, even if some trailers with
+the same (<token>, <value>) pair are already in the message.
++
+With `replace`, an existing trailer with the same <token> will be
+deleted and the new trailer will be added. The deleted trailer will be
+the closest one (with the same <token>) to the place where the new one
+will be added.
++
+With `doNothing`, nothing will be done; that is no new trailer will be
+added if there is already one with the same <token> in the message.
+
+trailer.ifmissing::
+	This option makes it possible to choose what action will be
+	performed when there is not yet any trailer with the same
+	<token> in the message.
++
+The valid values for this option are: `add` (this is the default) and
+`doNothing`.
++
+With `add`, a new trailer will be added.
++
+With `doNothing`, nothing will be done.
+
+trailer.<token>.key::
+	This `key` will be used instead of <token> in the trailer. At
+	the end of this key, a separator can appear and then some
+	space characters. By default the only valid separator is ':',
+	but this can be changed using the `trailer.separators` config
+	variable.
++
+If there is a separator, then the key will be used instead of both the
+<token> and the default separator when adding the trailer.
+
+trailer.<token>.where::
+	This option takes the same values as the 'trailer.where'
+	configuration variable and it overrides what is specified by
+	that option for trailers with the specified <token>.
+
+trailer.<token>.ifexist::
+	This option takes the same values as the 'trailer.ifexist'
+	configuration variable and it overrides what is specified by
+	that option for trailers with the specified <token>.
+
+trailer.<token>.ifmissing::
+	This option takes the same values as the 'trailer.ifmissing'
+	configuration variable and it overrides what is specified by
+	that option for trailers with the specified <token>.
+
+trailer.<token>.command::
+	This option can be used to specify a shell command that will
+	be called to automatically add or modify a trailer with the
+	specified <token>.
++
+When this option is specified, the behavior is as if a special
+'<token>=<value>' argument were added at the beginning of the command
+line, where <value> is taken to be the standard output of the
+specified command with any leading and trailing whitespace trimmed
+off.
++
+If the command contains the `$ARG` string, this string will be
+replaced with the <value> part of an existing trailer with the same
+<token>, if any, before the command is launched.
++
+If some '<token>=<value>' arguments are also passed on the command
+line, when a 'trailer.<token>.command' is configured, the command will
+also be executed for each of these arguments. And the <value> part of
+these arguments, if any, will be used to replace the `$ARG` string in
+the command.
+
+EXAMPLES
+--------
+
+* Configure a 'sign' trailer with a 'Signed-off-by' key, and then
+  add two of these trailers to a message:
++
+------------

+
+message
+
+Signed-off-by: Alice <alice@example.com>
+Signed-off-by: Bob <bob@example.com>
+------------
+
+* Extract the last commit as a patch, and add a 'Cc' and a
+  'Reviewed-by' trailer to it:
++
+------------
+$ git format-patch -1
+0001-foo.patch
+$ git interpret-trailers --trailer 'Cc: Alice <alice@example.com>' --trailer 'Reviewed-by: Bob <bob@example.com>' 0001-foo.patch >0001-bar.patch
+------------
+
+* Configure a 'sign' trailer with a command to automatically add a
+  'Signed-off-by: ' with the author information only if there is no
+  'Signed-off-by: ' already, and show how it works:
++
+------------
+$ git config trailer.sign.key "Signed-off-by: "
+$ git config trailer.sign.ifmissing add
+$ git config trailer.sign.ifexists doNothing
+$ git config trailer.sign.command 'echo "$(git config user.name) <$(git config user.email)>"'
+$ git interpret-trailers <<EOF

+$ git interpret-trailers <<EOF
+> Signed-off-by: Alice <alice@example.com>
+> EOF
+
+Signed-off-by: Alice <alice@example.com>
+------------
+
+* Configure a 'fix' trailer with a key that contains a '#' and no
+  space after this character, and show how it works:
++
+------------
+$ git config trailer.separators ":#"
+$ git config trailer.fix.key "Fix #"
+$ echo "subject" | git interpret-trailers --trailer fix=42
+subject
+
+Fix #42
+------------
+
+* Configure a 'see' trailer with a command to show the subject of a
+  commit that is related, and show how it works:
++
+------------
+$ git config trailer.see.key "See-also: "
+$ git config trailer.see.ifExists "replace"
+$ git config trailer.see.ifMissing "doNothing"
+$ git config trailer.see.command "git log -1 --oneline --format=\"%h (%s)\" --abbrev-commit --abbrev=14 \$ARG"
+$ git interpret-trailers <<EOF
+> subject
+> 
+> message
+> 
+> see: HEAD~2
+> EOF
+subject
+
+message
+
+See-also: fe3187489d69c4 (subject of related commit)
+------------
+
+* Configure a commit template with some trailers with empty values
+  (using sed to show and keep the trailing spaces at the end of the
+  trailers), then configure a commit-msg hook that uses
+  'git interpret-trailers' to remove trailers with empty values and
+  to add a 'git-version' trailer:
++
+------------
+$ sed -e 's/ Z$/ /' >commit_template.txt <<EOF
+> ***subject***
+> 
+> ***message***
+> 
+> Fixes: Z
+> Cc: Z
+> Reviewed-by: Z
+> Signed-off-by: Z
+> EOF
+$ git config commit.template commit_template.txt
+$ cat >.git/hooks/commit-msg <<EOF
+> #!/bin/sh
+> git interpret-trailers --trim-empty --trailer "git-version: \$(git describe)" "\$1" > "\$1.new"

+-------------

+See linkgit:git-config[1] for core variables and linkgit:git-diff[1]
+for settings related to diff generation.
+
+format.pretty::
+	Default for the `--format` option.  (See 'Pretty Formats' above.)
+	Defaults to `medium`.
+
+i18n.logOutputEncoding::
+	Encoding to use when displaying logs.  (See 'Discussion' above.)
+	Defaults to the value of `i18n.commitEncoding` if set, and UTF-8
+	otherwise.
+
+log.date::
+	Default format for human-readable dates.  (Compare the
+	`--date` option.)  Defaults to "default", which means to write
+	dates like `Sat May 8 19:35:34 2010 -0500`.
+
+log.showroot::
+	If `false`, `git log` and related commands will not treat the
+	initial commit as a big creation event.  Any root commits in
+	`git log -p` output would be shown without a diff attached.
+	The default is `true`.
+
+mailmap.*::
+	See linkgit:git-shortlog[1].
+
+notes.displayRef::
+	Which refs, in addition to the default set by `core.notesRef`
+	or 'GIT_NOTES_REF', to read notes from when showing commit
+	messages with the `log` family of commands.  See
+	linkgit:git-notes[1].
++
+May be an unabbreviated ref name or a glob and may be specified
+multiple times.  A warning will be issued for refs that do not exist,
+but a glob that does not match any refs is silently ignored.
++
+This setting can be disabled by the `--no-notes` option,
+overridden by the 'GIT_NOTES_DISPLAY_REF' environment variable,
+and overridden by the `--notes=<ref>` option.

-git-lost-found - Recover lost refs that luckily have not yet been pruned
-
-SYNOPSIS
---------
-'git lost-found'
-
-DESCRIPTION
------------
-
-*NOTE*: this command is deprecated.  Use linkgit:git-fsck[1] with
-the option '--lost-found' instead.
-
-Finds dangling commits and tags from the object database, and
-creates refs to them in the .git/lost-found/ directory.  Commits and
-tags that dereference to commits are stored in .git/lost-found/commit,
-and other objects are stored in .git/lost-found/other.
-
-
-OUTPUT
-------
-Prints to standard output the object names and one-line descriptions
-of any commits or tags found.
-
-EXAMPLE
--------
-
-Suppose you run 'git tag -f' and mistype the tag to overwrite.
-The ref to your tag is overwritten, but until you run 'git
-prune', the tag itself is still there.

+Discussion on fork-point mode
+-----------------------------
+
+After working on the `topic` branch created with `git checkout -b
+topic origin/master`, the history of remote-tracking branch
+`origin/master` may have been rewound and rebuilt, leading to a
+history of this shape:
+
+			 o---B1
+			/
+	---o---o---B2--o---o---o---B (origin/master)
+		\
+		 B3
+		  \
+		   Derived (topic)
+
+where `origin/master` used to point at commits B3, B2, B1 and now it
+points at B, and your `topic` branch was started on top of it back
+when `origin/master` was at B3. This mode uses the reflog of
+`origin/master` to find B3 as the fork point, so that the `topic`
+can be rebased on top of the updated `origin/master` by:
+
+    $ fork_point=$(git merge-base --fork-point origin/master topic)
+    $ git rebase --onto origin/master $fork_point topic

-HOW MERGE WORKS
----------------
-
-A merge is always between the current `HEAD` and one or more
-commits (usually, branch head or tag), and the index file must
-match the tree of `HEAD` commit (i.e. the contents of the last commit)
-when it starts out.  In other words, `git diff --cached HEAD` must
-report no changes.  (One exception is when the changed index
-entries are already in the same state that would result from
-the merge anyway.)
-
-Three kinds of merge can happen:
-
-* The merged commit is already contained in `HEAD`. This is the
-  simplest case, called "Already up-to-date."
-
-* `HEAD` is already contained in the merged commit. This is the
-  most common case especially when invoked from 'git pull':
-  you are tracking an upstream repository, have committed no local
-  changes and now you want to update to a newer upstream revision.
-  Your `HEAD` (and the index) is updated to point at the merged
-  commit, without creating an extra merge commit.  This is
-  called "Fast-forward".
-
-* Both the merged commit and `HEAD` are independent and must be
-  tied together by a merge commit that has both of them as its parents.
-  The rest of this section describes this "True merge" case.
-
-The chosen merge strategy merges the two commits into a single
-new source tree.
-When things merge cleanly, this is what happens:
-
-1. The results are updated both in the index file and in your
-   working tree;
-2. Index file is written out as a tree;
-3. The tree gets committed; and
-4. The `HEAD` pointer gets advanced.
-
-Because of 2., we require that the original state of the index
-file matches exactly the current `HEAD` commit; otherwise we
-will write out your local changes already registered in your
-index file along with the merge result, which is not good.
-Because 1. involves only those paths differing between your
-branch and the remote branch you are pulling from during the
-merge (which is typically a fraction of the whole tree), you can
-have local modifications in your working tree as long as they do
-not overlap with what the merge updates.
-
-When there are conflicts, the following happens:
-
-1. `HEAD` stays the same.
-
-2. Cleanly merged paths are updated both in the index file and

+
+
+PRE-MERGE CHECKS
+----------------
+
+Before applying outside changes, you should get your own work in
+good shape and committed locally, so it will not be clobbered if
+there are conflicts.  See also linkgit:git-stash[1].
+'git pull' and 'git merge' will stop without doing anything when
+local uncommitted changes overlap with files that 'git pull'/'git
+merge' may need to update.
+
+To avoid recording unrelated changes in the merge commit,
+'git pull' and 'git merge' will also abort if there are any changes
+registered in the index relative to the `HEAD` commit.  (One
+exception is when the changed index entries are in the state that
+would result from the merge already.)
+
+If all named commits are already ancestors of `HEAD`, 'git merge'
+will exit early with the message "Already up-to-date."
+
+FAST-FORWARD MERGE
+------------------
+
+Often the current branch head is an ancestor of the named commit.
+This is the most common case especially when invoked from 'git
+pull': you are tracking an upstream repository, you have committed
+no local changes, and now you want to update to a newer upstream
+revision.  In this case, a new commit is not needed to store the
+combined history; instead, the `HEAD` (along with the index) is
+updated to point at the named commit, without creating an extra
+merge commit.
+
+This behavior can be suppressed with the `--no-ff` option.
+
+TRUE MERGE
+----------
+
+Except in a fast-forward merge (see above), the branches to be
+merged must be tied together by a merge commit that has both of them
+as its parents.
+
+A merged version reconciling the changes from all branches to be
+merged is committed, and your `HEAD`, index, and working tree are
+updated to it.  It is possible to have modifications in the working
+tree as long as they do not overlap; the update will preserve them.
+
+When it is not obvious how to reconcile the changes, the following
+happens:
+
+1. The `HEAD` pointer stays the same.
+2. The `MERGE_HEAD` ref is set to point to the other branch head.
+3. Paths that merged cleanly are updated both in the index file and
    in your working tree.

+4. For conflicting paths, the index file records up to three
+   versions: stage 1 stores the version from the common ancestor,
+   stage 2 from `HEAD`, and stage 3 from `MERGE_HEAD` (you
    can inspect the stages with `git ls-files -u`).  The working
    tree files contain the result of the "merge" program; i.e. 3-way
-   merge results with familiar conflict markers `<<< === >>>`.
-
-4. No other changes are done.  In particular, the local
+   merge results with familiar conflict markers `<<<` `===` `>>>`.
+5. No other changes are made.  In particular, the local
    modifications you had before you started merge will stay the
    same and the index entries for them stay as they were,
    i.e. matching `HEAD`.
 
+If you tried a merge which resulted in complex conflicts and
+want to start over, you can recover with `git merge --abort`.
+
+MERGING TAG
+-----------
+
+When merging an annotated (and possibly signed) tag, Git always
+creates a merge commit even if a fast-forward merge is possible, and
+the commit message template is prepared with the tag message.
+Additionally, if the tag is signed, the signature check is reported
+as a comment in the message template. See also linkgit:git-tag[1].
+
+When you want to just integrate with the work leading to the commit
+that happens to be tagged, e.g. synchronizing with an upstream
+release point, you may not want to make an unnecessary merge commit.
+
+In such a case, you can "unwrap" the tag yourself before feeding it
+to `git merge`, or pass `--ff-only` when you do not have any work on
+your own. e.g.
+
+----
+git fetch origin
+git merge v1.2.3^0
+git merge --ff-only v1.2.3

+BUGS
+----
+Each time a superproject update moves a populated submodule (e.g. when
+switching between commits before and after the move) a stale submodule
+checkout will remain in the old location and an empty directory will
+appear in the new location. To populate the submodule again in the new
+location the user will have to run "git submodule update"
+afterwards. Removing the old directory is only safe when it uses a
+gitfile, as otherwise the history of the submodule will be deleted
+too. Both steps will be obsolete when recursive submodule update has
+been implemented.

+
+DESCRIPTION
+-----------
+Adds, removes, or reads notes attached to objects, without touching
+the objects themselves.
+
+By default, notes are saved to and read from `refs/notes/commits`, but
+this default can be overridden.  See the OPTIONS, CONFIGURATION, and
+ENVIRONMENT sections below.  If this ref does not exist, it will be
+quietly created when it is first needed to store a note.
+
+A typical use of notes is to supplement a commit message without
+changing the commit itself. Notes can be shown by 'git log' along with
+the original commit message. To distinguish these notes from the
+message stored in the commit object, the notes are indented like the
+message, after an unindented line saying "Notes (<refname>):" (or
+"Notes:" for `refs/notes/commits`).
+
+Notes can also be added to patches prepared with `git format-patch` by
+using the `--notes` option. Such notes are added as a patch commentary
+after a three dash separator line.
+
+To change which notes are shown by 'git log', see the
+"notes.displayRef" configuration in linkgit:git-log[1].
+
+See the "notes.rewrite.<command>" configuration for a way to carry
+notes across commands that rewrite commits.
+
+
+SUBCOMMANDS
+-----------
+
+list::
+	List the notes object for a given object. If no object is
+	given, show a list of all note objects and the objects they
+	annotate (in the format "<note object> <annotated object>").
+	This is the default subcommand if no subcommand is given.
+
+add::
+	Add notes for a given object (defaults to HEAD). Abort if the
+	object already has notes (use `-f` to overwrite existing notes).
+	However, if you're using `add` interactively (using an editor
+	to supply the notes contents), then - instead of aborting -
+	the existing notes will be opened in the editor (like the `edit`
+	subcommand).
+
+copy::
+	Copy the notes for the first object onto the second object.
+	Abort if the second object already has notes, or if the first
+	object has none (use -f to overwrite existing notes to the
+	second object). This subcommand is equivalent to:
+	`git notes add [-f] -C $(git notes list <from-object>) <to-object>`
++
+In `--stdin` mode, take lines in the format
++
+----------
+<from-object> SP <to-object> [ SP <rest> ] LF
+----------
++
+on standard input, and copy the notes from each <from-object> to its
+corresponding <to-object>.  (The optional `<rest>` is ignored so that
+the command can read the input given to the `post-rewrite` hook.)
+
+append::
+	Append to the notes of an existing object (defaults to HEAD).
+	Creates a new notes object if needed.
+
+edit::
+	Edit the notes for a given object (defaults to HEAD).
+
+show::
+	Show the notes for a given object (defaults to HEAD).
+
+merge::
+	Merge the given notes ref into the current notes ref.
+	This will try to merge the changes made by the given
+	notes ref (called "remote") since the merge-base (if
+	any) into the current notes ref (called "local").
++
+If conflicts arise and a strategy for automatically resolving
+conflicting notes (see the -s/--strategy option) is not given,
+the "manual" resolver is used. This resolver checks out the
+conflicting notes in a special worktree (`.git/NOTES_MERGE_WORKTREE`),
+and instructs the user to manually resolve the conflicts there.
+When done, the user can either finalize the merge with
+'git notes merge --commit', or abort the merge with
+'git notes merge --abort'.
+
+remove::
+	Remove the notes for given objects (defaults to HEAD). When
+	giving zero or one object from the command line, this is
+	equivalent to specifying an empty note message to
+	the `edit` subcommand.
+
+prune::
+	Remove all notes for non-existing/unreachable objects.
+
+get-ref::
+	Print the current notes ref. This provides an easy way to
+	retrieve the current notes ref (e.g. from scripts).
+

+
+--commit::
+	Finalize an in-progress 'git notes merge'. Use this option
+	when you have resolved the conflicts that 'git notes merge'
+	stored in .git/NOTES_MERGE_WORKTREE. This amends the partial
+	merge commit created by 'git notes merge' (stored in
+	.git/NOTES_MERGE_PARTIAL) by adding the notes in
+	.git/NOTES_MERGE_WORKTREE. The notes ref stored in the
+	.git/NOTES_MERGE_REF symref is updated to the resulting commit.
+
+--abort::
+	Abort/reset a in-progress 'git notes merge', i.e. a notes merge
+	with conflicts. This simply removes all files related to the
+	notes merge.
+
+-q::
+--quiet::
+	When merging notes, operate quietly.
+
+-v::
+--verbose::
+	When merging notes, be more verbose.
+	When pruning notes, report all object names whose notes are
+	removed.
+
+
+DISCUSSION
+----------
+
+Commit notes are blobs containing extra information about an object
+(usually information to supplement a commit's message).  These blobs
+are taken from notes refs.  A notes ref is usually a branch which
+contains "files" whose paths are the object names for the objects
+they describe, with some directory separators included for performance
+reasons footnote:[Permitted pathnames have the form
+'ab'`/`'cd'`/`'ef'`/`'...'`/`'abcdef...': a sequence of directory
+names of two hexadecimal digits each followed by a filename with the
+rest of the object ID.].
+
+Every notes change creates a new commit at the specified notes ref.
+You can therefore inspect the history of the notes by invoking, e.g.,
+`git log -p notes/commits`.  Currently the commit message only records
+which operation triggered the update, and the commit authorship is
+determined according to the usual rules (see linkgit:git-commit[1]).
+These details may change in the future.
+
+It is also permitted for a notes ref to point directly to a tree
+object, in which case the history of the notes can be read with
+`git log -p -g <refname>`.
+
+
+NOTES MERGE STRATEGIES
+----------------------
+
+The default notes merge strategy is "manual", which checks out
+conflicting notes in a special work tree for resolving notes conflicts
+(`.git/NOTES_MERGE_WORKTREE`), and instructs the user to resolve the
+conflicts in that work tree.
+When done, the user can either finalize the merge with
+'git notes merge --commit', or abort the merge with
+'git notes merge --abort'.
+
+"ours" automatically resolves conflicting notes in favor of the local
+version (i.e. the current notes ref).
+
+"theirs" automatically resolves notes conflicts in favor of the remote
+version (i.e. the given notes ref being merged into the current notes
+ref).
+
+"union" automatically resolves notes conflicts by concatenating the
+local and remote versions.
+
+"cat_sort_uniq" is similar to "union", but in addition to concatenating
+the local and remote versions, this strategy also sorts the resulting
+lines, and removes duplicate lines from the result. This is equivalent
+to applying the "cat | sort | uniq" shell pipeline to the local and
+remote versions. This strategy is useful if the notes follow a line-based
+format where one wants to avoid duplicated lines in the merge result.
+Note that if either the local or remote version contain duplicate lines
+prior to the merge, these will also be removed by this notes merge
+strategy.
+
+
+EXAMPLES
+--------
+
+You can use notes to add annotations with information that was not
+available at the time a commit was written.

+Notes:
+    Tested-by: Johannes Sixt <j6t@kdbg.org>
+------------
+
+In principle, a note is a regular Git blob, and any kind of
+(non-)format is accepted.  You can binary-safely create notes from
+arbitrary files using 'git hash-object':
+
+------------
+$ cc *.c
+$ blob=$(git hash-object -w a.out)
+$ git notes --ref=built add --allow-empty -C "$blob" HEAD
+------------
+
+(You cannot simply use `git notes --ref=built add -F a.out HEAD`
+because that is not binary-safe.)
+Of course, it doesn't make much sense to display non-text-format notes
+with 'git log', so if you use such notes, you'll probably need to write
+some special-purpose tools to do something useful with them.
+
+
+CONFIGURATION
+-------------
+
+core.notesRef::
+	Notes ref to read and manipulate instead of
+	`refs/notes/commits`.  Must be an unabbreviated ref name.
+	This setting can be overridden through the environment and
+	command line.
+
+notes.displayRef::
+	Which ref (or refs, if a glob or specified more than once), in
+	addition to the default set by `core.notesRef` or
+	'GIT_NOTES_REF', to read notes from when showing commit
+	messages with the 'git log' family of commands.
+	This setting can be overridden on the command line or by the
+	'GIT_NOTES_DISPLAY_REF' environment variable.

+
+notes.rewriteRef::
+	When copying notes during a rewrite, specifies the (fully

++
+Does not have a default value; you must configure this variable to

++
+Can be overridden with the 'GIT_NOTES_REWRITE_REF' environment variable.

+ENVIRONMENT
+-----------
+
+'GIT_NOTES_REF'::
+	Which ref to manipulate notes from, instead of `refs/notes/commits`.
+	This overrides the `core.notesRef` setting.
+
+'GIT_NOTES_DISPLAY_REF'::

+	in addition to the default from `core.notesRef` or
+	'GIT_NOTES_REF', to read notes from when showing commit
+	messages.
+	This overrides the `notes.displayRef` setting.
++
+A warning will be issued for refs that do not exist, but a glob that
+does not match any refs is silently ignored.
+
+'GIT_NOTES_REWRITE_MODE'::
+	When copying notes during a rewrite, what to do if the target
+	commit already has a note.
+	Must be one of `overwrite`, `concatenate`, and `ignore`.

+
+'GIT_NOTES_REWRITE_REF'::
+	When rewriting commits, which notes to copy from the original
+	to the rewritten commit.  Must be a colon-delimited list of
+	refs or globs.
++
+If not set in the environment, the list of notes to copy depends
+on the `notes.rewrite.<command>` and `notes.rewriteRef` settings.

+git-p4 - Import from and submit to Perforce repositories
+
+
+SYNOPSIS
+--------
+[verse]
+'git p4 clone' [<sync options>] [<clone options>] <p4 depot path>...
+'git p4 sync' [<sync options>] [<p4 depot path>...]
+'git p4 rebase'
+'git p4 submit' [<submit options>] [<master branch name>]
+
+
+DESCRIPTION
+-----------
+This command provides a way to interact with p4 repositories
+using Git.
+
+Create a new Git repository from an existing p4 repository using
+'git p4 clone', giving it one or more p4 depot paths.  Incorporate
+new commits from p4 changes with 'git p4 sync'.  The 'sync' command
+is also used to include new branches from other p4 depot paths.
+Submit Git changes back to p4 using 'git p4 submit'.  The command
+'git p4 rebase' does a sync plus rebases the current branch onto
+the updated p4 remote branch.
+
+
+EXAMPLE
+-------
+* Clone a repository:
++
+------------
+$ git p4 clone //depot/path/project
+------------
+
+* Do some work in the newly created Git repository:
++
+------------
+$ cd project
+$ vi foo.h
+$ git commit -a -m "edited foo.h"
+------------
+
+* Update the Git repository with recent changes from p4, rebasing your
+  work on top:
++
+------------
+$ git p4 rebase
+------------
+
+* Submit your commits back to p4:
++
+------------
+$ git p4 submit
+------------
+
+
+COMMANDS
+--------
+
+Clone
+~~~~~
+Generally, 'git p4 clone' is used to create a new Git directory
+from an existing p4 repository:
+------------
+$ git p4 clone //depot/path/project
+------------
+This:
+
+1.   Creates an empty Git repository in a subdirectory called 'project'.
++
+2.   Imports the full contents of the head revision from the given p4
+depot path into a single commit in the Git branch 'refs/remotes/p4/master'.
++
+3.   Creates a local branch, 'master' from this remote and checks it out.
+
+To reproduce the entire p4 history in Git, use the '@all' modifier on
+the depot path:
+------------
+$ git p4 clone //depot/path/project@all
+------------
+
+
+Sync
+~~~~
+As development continues in the p4 repository, those changes can
+be included in the Git repository using:
+------------
+$ git p4 sync
+------------
+This command finds new changes in p4 and imports them as Git commits.
+
+P4 repositories can be added to an existing Git repository using
+'git p4 sync' too:
+------------
+$ mkdir repo-git
+$ cd repo-git
+$ git init
+$ git p4 sync //path/in/your/perforce/depot
+------------
+This imports the specified depot into
+'refs/remotes/p4/master' in an existing Git repository.  The
+'--branch' option can be used to specify a different branch to
+be used for the p4 content.
+
+If a Git repository includes branches 'refs/remotes/origin/p4', these
+will be fetched and consulted first during a 'git p4 sync'.  Since
+importing directly from p4 is considerably slower than pulling changes
+from a Git remote, this can be useful in a multi-developer environment.
+
+If there are multiple branches, doing 'git p4 sync' will automatically
+use the "BRANCH DETECTION" algorithm to try to partition new changes
+into the right branch.  This can be overridden with the '--branch'
+option to specify just a single branch to update.
+
+
+Rebase
+~~~~~~
+A common working pattern is to fetch the latest changes from the p4 depot
+and merge them with local uncommitted changes.  Often, the p4 repository
+is the ultimate location for all code, thus a rebase workflow makes
+sense.  This command does 'git p4 sync' followed by 'git rebase' to move
+local commits on top of updated p4 changes.
+------------
+$ git p4 rebase
+------------
+
+
+Submit
+~~~~~~
+Submitting changes from a Git repository back to the p4 repository
+requires a separate p4 client workspace.  This should be specified
+using the 'P4CLIENT' environment variable or the Git configuration
+variable 'git-p4.client'.  The p4 client must exist, but the client root
+will be created and populated if it does not already exist.
+
+To submit all changes that are in the current Git branch but not in
+the 'p4/master' branch, use:
+------------
+$ git p4 submit
+------------
+
+To specify a branch other than the current one, use:
+------------
+$ git p4 submit topicbranch
+------------
+
+The upstream reference is generally 'refs/remotes/p4/master', but can
+be overridden using the '--origin=' command-line option.
+
+The p4 changes will be created as the user invoking 'git p4 submit'. The
+'--preserve-user' option will cause ownership to be modified
+according to the author of the Git commit.  This option requires admin
+privileges in p4, which can be granted using 'p4 protect'.
+
+
+OPTIONS
+-------
+
+General options
+~~~~~~~~~~~~~~~
+All commands except clone accept these options.
+
+--git-dir <dir>::
+	Set the 'GIT_DIR' environment variable.  See linkgit:git[1].
+
+-v::
+--verbose::
+	Provide more progress information.
+
+Sync options
+~~~~~~~~~~~~
+These options can be used in the initial 'clone' as well as in
+subsequent 'sync' operations.
+
+--branch <ref>::
+	Import changes into <ref> instead of refs/remotes/p4/master.
+	If <ref> starts with refs/, it is used as is.  Otherwise, if
+	it does not start with p4/, that prefix is added.
++
+By default a <ref> not starting with refs/ is treated as the
+name of a remote-tracking branch (under refs/remotes/).  This
+behavior can be modified using the --import-local option.
++
+The default <ref> is "master".
++
+This example imports a new remote "p4/proj2" into an existing
+Git repository:
++
+----
+    $ git init
+    $ git p4 sync --branch=refs/remotes/p4/proj2 //depot/proj2
+----
+
+--detect-branches::
+	Use the branch detection algorithm to find new paths in p4.  It is
+	documented below in "BRANCH DETECTION".
+
+--changesfile <file>::
+	Import exactly the p4 change numbers listed in 'file', one per
+	line.  Normally, 'git p4' inspects the current p4 repository
+	state and detects the changes it should import.
+
+--silent::
+	Do not print any progress information.
+
+--detect-labels::
+	Query p4 for labels associated with the depot paths, and add
+	them as tags in Git. Limited usefulness as only imports labels
+	associated with new changelists. Deprecated.
+
+--import-labels::
+	Import labels from p4 into Git.
+
+--import-local::
+	By default, p4 branches are stored in 'refs/remotes/p4/',
+	where they will be treated as remote-tracking branches by
+	linkgit:git-branch[1] and other commands.  This option instead
+	puts p4 branches in 'refs/heads/p4/'.  Note that future
+	sync operations must specify '--import-local' as well so that
+	they can find the p4 branches in refs/heads.
+
+--max-changes <n>::
+	Limit the number of imported changes to 'n'.  Useful to
+	limit the amount of history when using the '@all' p4 revision
+	specifier.
+
+--keep-path::
+	The mapping of file names from the p4 depot path to Git, by
+	default, involves removing the entire depot path.  With this
+	option, the full p4 depot path is retained in Git.  For example,
+	path '//depot/main/foo/bar.c', when imported from
+	'//depot/main/', becomes 'foo/bar.c'.  With '--keep-path', the
+	Git path is instead 'depot/main/foo/bar.c'.
+
+--use-client-spec::
+	Use a client spec to find the list of interesting files in p4.
+	See the "CLIENT SPEC" section below.
+
+Clone options
+~~~~~~~~~~~~~
+These options can be used in an initial 'clone', along with the 'sync'
+options described above.
+
+--destination <directory>::
+	Where to create the Git repository.  If not provided, the last
+	component in the p4 depot path is used to create a new
+	directory.
+
+--bare::
+	Perform a bare clone.  See linkgit:git-clone[1].
+
+-/ <path>::
+	Exclude selected depot paths when cloning.
+
+Submit options
+~~~~~~~~~~~~~~
+These options can be used to modify 'git p4 submit' behavior.
+
+--origin <commit>::
+	Upstream location from which commits are identified to submit to
+	p4.  By default, this is the most recent p4 commit reachable
+	from 'HEAD'.
+
+-M::
+	Detect renames.  See linkgit:git-diff[1].  Renames will be
+	represented in p4 using explicit 'move' operations.  There
+	is no corresponding option to detect copies, but there are
+	variables for both moves and copies.
+
+--preserve-user::
+	Re-author p4 changes before submitting to p4.  This option
+	requires p4 admin privileges.
+
+--export-labels::
+	Export tags from Git as p4 labels. Tags found in Git are applied
+	to the perforce working directory.
+
+-n::
+--dry-run::
+	Show just what commits would be submitted to p4; do not change
+	state in Git or p4.
+
+--prepare-p4-only::
+	Apply a commit to the p4 workspace, opening, adding and deleting
+	files in p4 as for a normal submit operation.  Do not issue the
+	final "p4 submit", but instead print a message about how to
+	submit manually or revert.  This option always stops after the
+	first (oldest) commit.  Git tags are not exported to p4.
+
+--conflict=(ask|skip|quit)::
+	Conflicts can occur when applying a commit to p4.  When this
+	happens, the default behavior ("ask") is to prompt whether to
+	skip this commit and continue, or quit.  This option can be used
+	to bypass the prompt, causing conflicting commits to be automatically
+	skipped, or to quit trying to apply commits, without prompting.
+
+--branch <branch>::
+	After submitting, sync this named branch instead of the default
+	p4/master.  See the "Sync options" section above for more
+	information.
+
+Rebase options
+~~~~~~~~~~~~~~
+These options can be used to modify 'git p4 rebase' behavior.
+
+--import-labels::
+	Import p4 labels.
+
+DEPOT PATH SYNTAX
+-----------------
+The p4 depot path argument to 'git p4 sync' and 'git p4 clone' can
+be one or more space-separated p4 depot paths, with an optional
+p4 revision specifier on the end:
+
+"//depot/my/project"::
+    Import one commit with all files in the '#head' change under that tree.
+
+"//depot/my/project@all"::
+    Import one commit for each change in the history of that depot path.
+
+"//depot/my/project@1,6"::
+    Import only changes 1 through 6.
+
+"//depot/proj1@all //depot/proj2@all"::
+    Import all changes from both named depot paths into a single
+    repository.  Only files below these directories are included.
+    There is not a subdirectory in Git for each "proj1" and "proj2".
+    You must use the '--destination' option when specifying more
+    than one depot path.  The revision specifier must be specified
+    identically on each depot path.  If there are files in the
+    depot paths with the same name, the path with the most recently
+    updated version of the file is the one that appears in Git.
+
+See 'p4 help revisions' for the full syntax of p4 revision specifiers.
+
+
+CLIENT SPEC
+-----------
+The p4 client specification is maintained with the 'p4 client' command
+and contains among other fields, a View that specifies how the depot
+is mapped into the client repository.  The 'clone' and 'sync' commands
+can consult the client spec when given the '--use-client-spec' option or
+when the useClientSpec variable is true.  After 'git p4 clone', the
+useClientSpec variable is automatically set in the repository
+configuration file.  This allows future 'git p4 submit' commands to
+work properly; the submit command looks only at the variable and does
+not have a command-line option.
+
+The full syntax for a p4 view is documented in 'p4 help views'.  'git p4'
+knows only a subset of the view syntax.  It understands multi-line
+mappings, overlays with '+', exclusions with '-' and double-quotes
+around whitespace.  Of the possible wildcards, 'git p4' only handles
+'...', and only when it is at the end of the path.  'git p4' will complain
+if it encounters an unhandled wildcard.
+
+Bugs in the implementation of overlap mappings exist.  If multiple depot
+paths map through overlays to the same location in the repository,
+'git p4' can choose the wrong one.  This is hard to solve without
+dedicating a client spec just for 'git p4'.
+
+The name of the client can be given to 'git p4' in multiple ways.  The
+variable 'git-p4.client' takes precedence if it exists.  Otherwise,
+normal p4 mechanisms of determining the client are used:  environment
+variable P4CLIENT, a file referenced by P4CONFIG, or the local host name.
+
+
+BRANCH DETECTION
+----------------
+P4 does not have the same concept of a branch as Git.  Instead,
+p4 organizes its content as a directory tree, where by convention
+different logical branches are in different locations in the tree.
+The 'p4 branch' command is used to maintain mappings between
+different areas in the tree, and indicate related content.  'git p4'
+can use these mappings to determine branch relationships.
+
+If you have a repository where all the branches of interest exist as
+subdirectories of a single depot path, you can use '--detect-branches'
+when cloning or syncing to have 'git p4' automatically find
+subdirectories in p4, and to generate these as branches in Git.
+
+For example, if the P4 repository structure is:
+----
+//depot/main/...
+//depot/branch1/...
+----
+
+And "p4 branch -o branch1" shows a View line that looks like:
+----
+//depot/main/... //depot/branch1/...
+----
+
+Then this 'git p4 clone' command:
+----
+git p4 clone --detect-branches //depot@all
+----
+produces a separate branch in 'refs/remotes/p4/' for //depot/main,
+called 'master', and one for //depot/branch1 called 'depot/branch1'.
+
+However, it is not necessary to create branches in p4 to be able to use
+them like branches.  Because it is difficult to infer branch
+relationships automatically, a Git configuration setting
+'git-p4.branchList' can be used to explicitly identify branch
+relationships.  It is a list of "source:destination" pairs, like a
+simple p4 branch specification, where the "source" and "destination" are
+the path elements in the p4 repository.  The example above relied on the
+presence of the p4 branch.  Without p4 branches, the same result will
+occur with:
+----
+git init depot
+cd depot
+git config git-p4.branchList main:branch1
+git p4 clone --detect-branches //depot@all .
+----
+
+
+PERFORMANCE
+-----------
+The fast-import mechanism used by 'git p4' creates one pack file for
+each invocation of 'git p4 sync'.  Normally, Git garbage compression
+(linkgit:git-gc[1]) automatically compresses these to fewer pack files,
+but explicit invocation of 'git repack -adf' may improve performance.
+
+
+CONFIGURATION VARIABLES
+-----------------------
+The following config settings can be used to modify 'git p4' behavior.
+They all are in the 'git-p4' section.
+
+General variables
+~~~~~~~~~~~~~~~~~
+git-p4.user::
+	User specified as an option to all p4 commands, with '-u <user>'.
+	The environment variable 'P4USER' can be used instead.
+
+git-p4.password::
+	Password specified as an option to all p4 commands, with
+	'-P <password>'.
+	The environment variable 'P4PASS' can be used instead.
+
+git-p4.port::
+	Port specified as an option to all p4 commands, with
+	'-p <port>'.
+	The environment variable 'P4PORT' can be used instead.
+
+git-p4.host::
+	Host specified as an option to all p4 commands, with
+	'-h <host>'.
+	The environment variable 'P4HOST' can be used instead.
+
+git-p4.client::
+	Client specified as an option to all p4 commands, with
+	'-c <client>', including the client spec.
+
+Clone and sync variables
+~~~~~~~~~~~~~~~~~~~~~~~~
+git-p4.syncFromOrigin::
+	Because importing commits from other Git repositories is much faster
+	than importing them from p4, a mechanism exists to find p4 changes
+	first in Git remotes.  If branches exist under 'refs/remote/origin/p4',
+	those will be fetched and used when syncing from p4.  This
+	variable can be set to 'false' to disable this behavior.
+
+git-p4.branchUser::
+	One phase in branch detection involves looking at p4 branches
+	to find new ones to import.  By default, all branches are
+	inspected.  This option limits the search to just those owned
+	by the single user named in the variable.
+
+git-p4.branchList::
+	List of branches to be imported when branch detection is
+	enabled.  Each entry should be a pair of branch names separated
+	by a colon (:).  This example declares that both branchA and
+	branchB were created from main:
++
+-------------
+git config       git-p4.branchList main:branchA
+git config --add git-p4.branchList main:branchB
+-------------
+
+git-p4.ignoredP4Labels::
+	List of p4 labels to ignore. This is built automatically as
+	unimportable labels are discovered.
+
+git-p4.importLabels::
+	Import p4 labels into git, as per --import-labels.
+
+git-p4.labelImportRegexp::
+	Only p4 labels matching this regular expression will be imported. The
+	default value is '[a-zA-Z0-9_\-.]+$'.
+
+git-p4.useClientSpec::
+	Specify that the p4 client spec should be used to identify p4
+	depot paths of interest.  This is equivalent to specifying the
+	option '--use-client-spec'.  See the "CLIENT SPEC" section above.
+	This variable is a boolean, not the name of a p4 client.
+
+Submit variables
+~~~~~~~~~~~~~~~~
+git-p4.detectRenames::
+	Detect renames.  See linkgit:git-diff[1].  This can be true,
+	false, or a score as expected by 'git diff -M'.
+
+git-p4.detectCopies::
+	Detect copies.  See linkgit:git-diff[1].  This can be true,
+	false, or a score as expected by 'git diff -C'.
+
+git-p4.detectCopiesHarder::
+	Detect copies harder.  See linkgit:git-diff[1].  A boolean.
+
+git-p4.preserveUser::
+	On submit, re-author changes to reflect the Git author,
+	regardless of who invokes 'git p4 submit'.
+
+git-p4.allowMissingP4Users::
+	When 'preserveUser' is true, 'git p4' normally dies if it
+	cannot find an author in the p4 user map.  This setting
+	submits the change regardless.
+
+git-p4.skipSubmitEdit::
+	The submit process invokes the editor before each p4 change
+	is submitted.  If this setting is true, though, the editing
+	step is skipped.
+
+git-p4.skipSubmitEditCheck::
+	After editing the p4 change message, 'git p4' makes sure that
+	the description really was changed by looking at the file
+	modification time.  This option disables that test.
+
+git-p4.allowSubmit::
+	By default, any branch can be used as the source for a 'git p4
+	submit' operation.  This configuration variable, if set, permits only
+	the named branches to be used as submit sources.  Branch names
+	must be the short names (no "refs/heads/"), and should be
+	separated by commas (","), with no spaces.
+
+git-p4.skipUserNameCheck::
+	If the user running 'git p4 submit' does not exist in the p4
+	user map, 'git p4' exits.  This option can be used to force
+	submission regardless.
+
+git-p4.attemptRCSCleanup::
+	If enabled, 'git p4 submit' will attempt to cleanup RCS keywords
+	($Header$, etc). These would otherwise cause merge conflicts and prevent
+	the submit going ahead. This option should be considered experimental at
+	present.
+
+git-p4.exportLabels::
+	Export Git tags to p4 labels, as per --export-labels.
+
+git-p4.labelExportRegexp::
+	Only p4 labels matching this regular expression will be exported. The
+	default value is '[a-zA-Z0-9_\-.]+$'.
+
+git-p4.conflict::
+	Specify submit behavior when a conflict with p4 is found, as per
+	--conflict.  The default behavior is 'ask'.
+
+IMPLEMENTATION DETAILS
+----------------------
+* Changesets from p4 are imported using Git fast-import.
+* Cloning or syncing does not require a p4 client; file contents are
+  collected using 'p4 print'.
+* Submitting requires a p4 client, which is not in the same location
+  as the Git repository.  Patches are applied, one at a time, to
+  this p4 client and submitted from there.
+* Each commit imported by 'git p4' has a line at the end of the log
+  message indicating the p4 depot location and change number.  This
+  line is used by later 'git p4 sync' operations to know which p4
+  changes are new.

 NAME
 ----
-git-pull - Fetch from and merge with another repository or a local branch

 SYNOPSIS
 --------
-'git pull' <options> <repository> <refspec>...
+[verse]
+'git pull' [options] [<repository> [<refspec>...]]
 
 
 DESCRIPTION
 -----------
-Runs 'git-fetch' with the given parameters, and calls 'git-merge'
-to merge the retrieved head(s) into the current branch.
-With `--rebase`, calls 'git-rebase' instead of 'git-merge'.
 
-Note that you can use `.` (current directory) as the
-<repository> to pull from the local repository -- this is useful
-when merging local branches into the current branch.
+Incorporates changes from a remote repository into the current
+branch.  In its default mode, `git pull` is shorthand for
+`git fetch` followed by `git merge FETCH_HEAD`.
 
-Also note that options meant for 'git-pull' itself and underlying
-'git-merge' must be given before the options meant for 'git-fetch'.
+More precisely, 'git pull' runs 'git fetch' with the given
+parameters and calls 'git merge' to merge the retrieved branch
+heads into the current branch.
+With `--rebase`, it runs 'git rebase' instead of 'git merge'.
+
+<repository> should be the name of a remote repository as
+passed to linkgit:git-fetch[1].  <refspec> can name an
+arbitrary remote ref (for example, the name of a tag) or even
+a collection of refs with corresponding remote-tracking branches
+(e.g., refs/heads/{asterisk}:refs/remotes/origin/{asterisk}),
+but usually it is the name of a branch in the remote repository.
+
+Default values for <repository> and <branch> are read from the
+"remote" and "merge" configuration for the current branch
+as set by linkgit:git-branch[1] `--track`.
+
+Assume the following history exists and the current branch is
+"`master`":
+
+------------
+	  A---B---C master on origin
+	 /
+    D---E---F---G master
+	^
+	origin/master in your repository
+------------
+
+Then "`git pull`" will fetch and replay the changes from the remote
+`master` branch since it diverged from the local `master` (i.e., `E`)
+until its current commit (`C`) on top of `master` and record the
+result in a new commit along with the names of the two parent commits
+and a log message from the user describing the changes.
+
+------------
+	  A---B---C origin/master
+	 /         \
+    D---E---F---G---H master
+------------
+
+See linkgit:git-merge[1] for details, including how conflicts
+are presented and handled.
+
+In Git 1.7.0 or later, to cancel a conflicting merge, use
+`git reset --merge`.  *Warning*: In older versions of Git, running 'git pull'
+with uncommitted changes is discouraged: while possible, it leaves you
+in a state that may be hard to back out of in the case of a conflict.
+
+If any of the remote changes overlap with local uncommitted changes,
+the merge will be automatically cancelled and the work tree untouched.
+It is generally best to get any local changes in working order before
+pulling or stash them away with linkgit:git-stash[1].

+Sparse checkout
+---------------
+
+"Sparse checkout" allows populating the working directory sparsely.
+It uses the skip-worktree bit (see linkgit:git-update-index[1]) to tell
+Git whether a file in the working directory is worth looking at.
+
+'git read-tree' and other merge-based commands ('git merge', 'git
+checkout'...) can help maintaining the skip-worktree bitmap and working
+directory update. `$GIT_DIR/info/sparse-checkout` is used to
+define the skip-worktree reference bitmap. When 'git read-tree' needs
+to update the working directory, it resets the skip-worktree bit in the index
+based on this file, which uses the same syntax as .gitignore files.
+If an entry matches a pattern in this file, skip-worktree will not be
+set on that entry. Otherwise, skip-worktree will be set.
+
+Then it compares the new skip-worktree value with the previous one. If
+skip-worktree turns from set to unset, it will add the corresponding
+file back. If it turns from unset to set, that file will be removed.
+
+While `$GIT_DIR/info/sparse-checkout` is usually used to specify what
+files are in, you can also specify what files are _not_ in, using
+negate patterns. For example, to remove the file `unwanted`:
+
+----------------
+/*
+!unwanted
+----------------
+
+Another tricky thing is fully repopulating the working directory when you
+no longer want sparse checkout. You cannot just disable "sparse
+checkout" because skip-worktree bits are still in the index and your working
+directory is still sparsely populated. You should re-populate the working
+directory with the `$GIT_DIR/info/sparse-checkout` file content as
+follows:
+
+----------------
+/*
+----------------
+
+Then you can disable sparse checkout. Sparse checkout support in 'git
+read-tree' and similar commands is disabled by default. You need to
+turn `core.sparseCheckout` on in order to have sparse checkout
+support.

+git remote add <nick> "ext::<command>[ <arguments>...]"
+
+DESCRIPTION
+-----------
+This remote helper uses the specified '<command>' to connect
+to a remote Git server.
+
+Data written to stdin of the specified '<command>' is assumed
+to be sent to a git:// server, git-upload-pack, git-receive-pack
+or git-upload-archive (depending on situation), and data read
+from stdout of <command> is assumed to be received from
+the same service.
+
+Command and arguments are separated by an unescaped space.
+
+The following sequences have a special meaning:
+
+'% '::
+	Literal space in command or argument.
+
+'%%'::
+	Literal percent sign.
+
+'%s'::
+	Replaced with name (receive-pack, upload-pack, or
+	upload-archive) of the service Git wants to invoke.
+
+'%S'::
+	Replaced with long name (git-receive-pack,
+	git-upload-pack, or git-upload-archive) of the service
+	Git wants to invoke.
+
+'%G' (must be the first characters in an argument)::

+, "git push <URL>" or "git remote add <nick> <URL>", where <URL>
+begins with `ext::`.  Examples:
+
+"ext::ssh -i /home/foo/.ssh/somekey user&#64;host.example %S 'foo/repo'"::
+	Like host.example:foo/repo, but use /home/foo/.ssh/somekey as
+	keypair and user as user on remote side. This avoids needing to
+	edit .ssh/config.
+
+"ext::socat -t3600 - ABSTRACT-CONNECT:/git-server %G/somerepo"::
+	Represents repository with path /somerepo accessible over
+	git protocol at abstract namespace address /git-server.
+
+"ext::git-server-alias foo %G/repo"::
+	Represents a repository with path /repo accessed using the
+	helper program "git-server-alias foo".  The path to the
+	repository and type of request are not passed on the command

+	protocol.
+
+"ext::git-server-alias foo %G/repo %Vfoo"::
+	Represents a repository with path /repo accessed using the
+	helper program "git-server-alias foo".  The hostname for the

+
+"ext::git-ssl foo.example /bar"::
+	Represents a repository accessed using the helper program

+NAME
+----
+git-remote-fd - Reflect smart transport stream back to caller
+
+SYNOPSIS
+--------
+"fd::<infd>[,<outfd>][/<anything>]" (as URL)
+
+DESCRIPTION
+-----------
+This helper uses specified file descriptors to connect to a remote Git server.
+This is not meant for end users but for programs and scripts calling git
+fetch, push or archive.
+
+If only <infd> is given, it is assumed to be a bidirectional socket connected
+to remote Git server (git-upload-pack, git-receive-pack or
+git-upload-achive). If both <infd> and <outfd> are given, they are assumed
+to be pipes connected to a remote Git server (<infd> being the inbound pipe
+and <outfd> being the outbound pipe.
+
+It is assumed that any handshaking procedures have already been completed
+(such as sending service request for git://) before this helper is started.
+
+<anything> can be any string. It is ignored. It is meant for providing
+information to user in the URL in case that URL is displayed in some
+context.
+
+ENVIRONMENT VARIABLES
+---------------------
+GIT_TRANSLOOP_DEBUG::
+	If set, prints debugging information about various reads/writes.
+
+EXAMPLES
+--------
+`git fetch fd::17 master`::
+	Fetch master, using file descriptor #17 to communicate with
+	git-upload-pack.
+
+`git fetch fd::17/foo master`::
+	Same as above.
+
+`git push fd::7,8 master (as URL)`::
+	Push master, using file descriptor #7 to read data from
+	git-receive-pack and file descriptor #8 to write data to
+	same service.
+
+`git push fd::7,8/bar master`::
+	Same as above.

-=====================
-
-NAME
-----
-git-remote-helpers - Helper programs for interoperation with remote git
-
-SYNOPSIS
---------
-'git remote-<transport>' <remote>
-
-DESCRIPTION
------------
-
-These programs are normally not used directly by end users, but are
-invoked by various git programs that interact with remote repositories
-when the repository they would operate on will be accessed using
-transport code not linked into the main git binary. Various particular
-helper programs will behave as documented here.
-
-COMMANDS
---------
-
-Commands are given by the caller on the helper's standard input, one per line.
-
-'capabilities'::
-	Lists the capabilities of the helper, one per line, ending
-	with a blank line.
-
-'list'::
-	Lists the refs, one per line, in the format "<value> <name>
-	[<attr> ...]". The value may be a hex sha1 hash, "@<dest>" for
-	a symref, or "?" to indicate that the helper could not get the
-	value of the ref. A space-separated list of attributes follows
-	the name; unrecognized attributes are ignored. After the
-	complete list, outputs a blank line.
-+
-If 'push' is supported this may be called as 'list for-push'
-to obtain the current refs prior to sending one or more 'push'
-commands to the helper.
-
-'option' <name> <value>::
-	Set the transport helper option <name> to <value>.  Outputs a
-	single line containing one of 'ok' (option successfully set),
-	'unsupported' (option not recognized) or 'error <msg>'
-	(option <name> is supported but <value> is not correct
-	for it).  Options should be set before other commands,
-	and may how those commands behave.
-+
-Supported if the helper has the "option" capability.
-
-'fetch' <sha1> <name>::
-	Fetches the given object, writing the necessary objects
-	to the database.  Fetch commands are sent in a batch, one
-	per line, and the batch is terminated with a blank line.
-	Outputs a single blank line when all fetch commands in the
-	same batch are complete. Only objects which were reported
-	in the ref list with a sha1 may be fetched this way.
-+
-Optionally may output a 'lock <file>' line indicating a file under
-GIT_DIR/objects/pack which is keeping a pack until refs can be
-suitably updated.
-+
-Supported if the helper has the "fetch" capability.
-
-'push' +<src>:<dst>::
-	Pushes the given <src> commit or branch locally to the
-	remote branch described by <dst>.  A batch sequence of
-	one or more push commands is terminated with a blank line.
-+
-Zero or more protocol options may be entered after the last 'push'
-command, before the batch's terminating blank line.
-+
-When the push is complete, outputs one or more 'ok <dst>' or
-'error <dst> <why>?' lines to indicate success or failure of
-each pushed ref.  The status report output is terminated by
-a blank line.  The option field <why> may be quoted in a C
-style string if it contains an LF.
-+
-Supported if the helper has the "push" capability.
-
-If a fatal error occurs, the program writes the error message to
-stderr and exits. The caller should expect that a suitable error
-message has been printed if the child closes the connection without
-completing a valid response for the current command.
-
-Additional commands may be supported, as may be determined from
-capabilities reported by the helper.
-
-CAPABILITIES
-------------
-
-'fetch'::
-	This helper supports the 'fetch' command.
-
-'option'::
-	This helper supports the option command.
-
-'push'::
-	This helper supports the 'push' command.
-
-REF LIST ATTRIBUTES
--------------------
-
-'for-push'::
-	The caller wants to use the ref list to prepare push
-	commands.  A helper might chose to acquire the ref list by
-	opening a different type of connection to the destination.
-
-OPTIONS
--------
-'option verbosity' <N>::
-	Change the level of messages displayed by the helper.
-	When N is 0 the end-user has asked the process to be
-	quiet, and the helper should produce only error output.
-	N of 1 is the default level of verbosity, higher values
-	of N correspond to the number of -v flags passed on the
-	command line.
-
-'option progress' \{'true'|'false'\}::
-	Enable (or disable) progress messages displayed by the
-	transport helper during a command.
-
-'option depth' <depth>::
-	Deepen the history of a shallow repository.
-
-'option followtags' \{'true'|'false'\}::
-	If enabled the helper should automatically fetch annotated
-	tag objects if the object the tag points at was transferred
-	during the fetch command.  If the tag is not fetched by
-	the helper a second fetch command will usually be sent to
-	ask for the tag specifically.  Some helpers may be able to
-	use this option to avoid a second network connection.
-
-'option dry-run' \{'true'|'false'\}:
-	If true, pretend the operation completed successfully,
-	but don't actually change any repository data.	For most
-	helpers this only applies to the 'push', if supported.

+By default, the command passes `--delta-base-offset` option to
+'git pack-objects'; this typically results in slightly smaller packs,
+but the generated packs are incompatible with versions of Git older than
+version 1.4.4. If you need to share your repository with such ancient Git
+versions, either directly or via the dumb http or rsync protocol, then you
+need to set the configuration variable `repack.UseDeltaBaseOffset` to
+"false" and repack. Access from old Git versions over the native protocol
+is unaffected by this option as the conversion is performed on the fly
+as needed in that case.

 replacement object.
 
-Unless `-f` is given, the replace reference must not yet exist in
-`.git/refs/replace/` directory.
+The replaced object and the replacement object must be of the same type.
+This restriction can be bypassed using `-f`.
+
+Unless `-f` is given, the 'replace' reference must not yet exist.
+
+There is no other restriction on the replaced and replacement objects.
+Merge commits can be replaced by non-merge commits and vice versa.
+
+Replacement references will be used by default by all Git commands
+except those doing reachability traversal (prune, pack transfer and
+fsck).
+
+It is possible to disable use of replacement references for any
+command using the `--no-replace-objects` option just after 'git'.
+
+For example if commit 'foo' has been replaced by commit 'bar':
+
+------------------------------------------------
+$ git --no-replace-objects cat-file commit foo
+------------------------------------------------
+
+shows information about commit 'foo', while:
+
+------------------------------------------------
+$ git cat-file commit foo
+------------------------------------------------
+
+shows information about commit 'bar'.
+
+The 'GIT_NO_REPLACE_OBJECTS' environment variable can be set to
+achieve the same effect as the `--no-replace-objects` option.
 
 OPTIONS
 -------
 -f::
+--force::
 	If an existing replace ref for the same object exists, it will
 	be overwritten (instead of failing).
 
 -d::
+--delete::
 	Delete existing replace refs for the given objects.
 
+--edit <object>::
+	Edit an object's content interactively. The existing content
+	for <object> is pretty-printed into a temporary file, an
+	editor is launched on the file, and the result is parsed to
+	create a new object of the same type as <object>. A
+	replacement ref is then created to replace <object> with the
+	newly created object. See linkgit:git-var[1] for details about
+	how the editor will be chosen.
+
+--raw::
+	When editing, provide the raw object contents rather than
+	pretty-printed ones. Currently this only affects trees, which
+	will be shown in their binary form. This is harder to work with,
+	but can help when repairing a tree that is so corrupted it
+	cannot be pretty-printed. Note that you may need to configure
+	your editor to cleanly read and write binary data.
+
+--graft <commit> [<parent>...]::
+	Create a graft commit. A new commit is created with the same
+	content as <commit> except that its parents will be
+	[<parent>...] instead of <commit>'s parents. A replacement ref
+	is then created to replace <commit> with the newly created
+	commit. See contrib/convert-grafts-to-replace-refs.sh for an
+	example script based on this option that can convert grafts to
+	replace refs.
+
 -l <pattern>::
+--list <pattern>::
 	List replace refs for objects that match the given pattern (or
 	all if no pattern is given).
 	Typing "git replace" without arguments, also lists all replace
 	refs.
 
+--format=<format>::
+	When listing, use the specified <format>, which can be one of
+	'short', 'medium' and 'long'. When omitted, the format
+	defaults to 'short'.
+
+FORMATS
+-------
+
+The following format are available:
+
+* 'short':
+	<replaced sha1>
+* 'medium':
+	<replaced sha1> -> <replacement sha1>
+* 'long':
+	<replaced sha1> (<replaced type>) -> <replacement sha1> (<replacement type>)
+
+CREATING REPLACEMENT OBJECTS
+----------------------------
+
+linkgit:git-filter-branch[1], linkgit:git-hash-object[1] and
+linkgit:git-rebase[1], among other git commands, can be used to create
+replacement objects from existing objects. The `--edit` option can
+also be used with 'git replace' to create a replacement object by
+editing an existing object.
+
+If you want to replace many blobs, trees or commits that are part of a
+string of commits, you may just want to create a replacement string of
+commits and then only replace the commit at the tip of the target
+string of commits with the commit at the tip of the replacement string
+of commits.
+
 BUGS
 ----
 Comparing blobs or trees that have been replaced with those that
-replace them will not work properly. And using 'git reset --hard' to
+replace them will not work properly. And using `git reset --hard` to
 go back to a replaced commit will move the branch to the replacement
 commit instead of the replaced commit.
 
 There may be other problems when using 'git rev-list' related to
-pending objects. And of course things may break if an object of one
-type is replaced by an object of another type (for example a blob
-replaced by a commit).

+Generate a request asking your upstream project to pull changes into
+their tree.  The request, printed to the standard output, summarizes

++
+This means that `git reset <paths>` is the opposite of `git add

+Keep changes in working tree while discarding some previous commits::

+Suppose you are working on something and you commit it, and then you
+continue working a bit more, but now you think that what you have in
+your working tree should be in another branch that has nothing to do
+with what you committed previously. You can start a new branch and

+The tables below show what happens when running:

+----------
+git reset --option target
+----------
+
+to reset the HEAD to another commit (`target`) with the different
+reset options depending on the state of the files.
+
+In these tables, A, B, C and D are some different states of a
+file. For example, the first line of the first table means that if a
+file is in state A in the working tree, in state B in the index, in
+state C in HEAD and in state D in the target, then "git reset --soft
+target" will leave the file in the working tree in state A and in the
+index in state B.  It resets (i.e. moves) the HEAD (i.e. the tip of
+the current branch, if you are on one) to "target" (which has the file
+in state D).

+"reset --merge" is meant to be used when resetting out of a conflicted
+merge. Any mergy operation guarantees that the working tree file that is
+involved in the merge does not have local change wrt the index before
+it starts, and that it writes the result out to the working tree. So if
+we see some difference between the index and the target and also
+between the index and the working tree, then it means that we are not
+resetting out from a state that a mergy operation left after failing
+with a conflict. That is why we disallow --merge option in this case.
+
+"reset --keep" is meant to be used when removing some of the last
+commits in the current branch while keeping changes in the working
+tree. If there could be conflicts between the changes in the commit we
+want to remove and the changes in the working tree we want to keep,
+the reset is disallowed. That's why it is disallowed if there are both
+changes between the working tree and HEAD, and between HEAD and the
+target. To be safe, it is also disallowed when there are unmerged
+entries.

-SPECIFYING REVISIONS
---------------------
-
-A revision parameter typically, but not necessarily, names a
-commit object.  They use what is called an 'extended SHA1'
-syntax.  Here are various ways to spell object names.  The
-ones listed near the end of this list are to name trees and
-blobs contained in a commit.
-
-* The full SHA1 object name (40-byte hexadecimal string), or
-  a substring of such that is unique within the repository.
-  E.g. dae86e1950b1277e545cee180551750029cfe735 and dae86e both
-  name the same commit object if there are no other object in
-  your repository whose object name starts with dae86e.
-
-* An output from 'git-describe'; i.e. a closest tag, optionally
-  followed by a dash and a number of commits, followed by a dash, a
-  `g`, and an abbreviated object name.
-
-* A symbolic ref name.  E.g. 'master' typically means the commit
-  object referenced by $GIT_DIR/refs/heads/master.  If you
-  happen to have both heads/master and tags/master, you can
-  explicitly say 'heads/master' to tell git which one you mean.
-  When ambiguous, a `<name>` is disambiguated by taking the
-  first match in the following rules:
-
-  . if `$GIT_DIR/<name>` exists, that is what you mean (this is usually
-    useful only for `HEAD`, `FETCH_HEAD`, `ORIG_HEAD` and `MERGE_HEAD`);
-
-  . otherwise, `$GIT_DIR/refs/<name>` if exists;
-
-  . otherwise, `$GIT_DIR/refs/tags/<name>` if exists;
-
-  . otherwise, `$GIT_DIR/refs/heads/<name>` if exists;
-
-  . otherwise, `$GIT_DIR/refs/remotes/<name>` if exists;
-
-  . otherwise, `$GIT_DIR/refs/remotes/<name>/HEAD` if exists.
-+
-HEAD names the commit your changes in the working tree is based on.
-FETCH_HEAD records the branch you fetched from a remote repository
-with your last 'git-fetch' invocation.
-ORIG_HEAD is created by commands that moves your HEAD in a drastic
-way, to record the position of the HEAD before their operation, so that
-you can change the tip of the branch back to the state before you ran
-them easily.
-MERGE_HEAD records the commit(s) you are merging into your branch
-when you run 'git-merge'.
-
-* A ref followed by the suffix '@' with a date specification
-  enclosed in a brace
-  pair (e.g. '\{yesterday\}', '\{1 month 2 weeks 3 days 1 hour 1
-  second ago\}' or '\{1979-02-26 18:30:00\}') to specify the value
-  of the ref at a prior point in time.  This suffix may only be
-  used immediately following a ref name and the ref must have an
-  existing log ($GIT_DIR/logs/<ref>). Note that this looks up the state
-  of your *local* ref at a given time; e.g., what was in your local
-  `master` branch last week. If you want to look at commits made during
-  certain times, see `--since` and `--until`.
-
-* A ref followed by the suffix '@' with an ordinal specification
-  enclosed in a brace pair (e.g. '\{1\}', '\{15\}') to specify
-  the n-th prior value of that ref.  For example 'master@\{1\}'
-  is the immediate prior value of 'master' while 'master@\{5\}'
-  is the 5th prior value of 'master'. This suffix may only be used
-  immediately following a ref name and the ref must have an existing
-  log ($GIT_DIR/logs/<ref>).
-
-* You can use the '@' construct with an empty ref part to get at a
-  reflog of the current branch. For example, if you are on the
-  branch 'blabla', then '@\{1\}' means the same as 'blabla@\{1\}'.
-
-* The special construct '@\{-<n>\}' means the <n>th branch checked out
-  before the current one.
-
-* A suffix '{caret}' to a revision parameter means the first parent of
-  that commit object.  '{caret}<n>' means the <n>th parent (i.e.
-  'rev{caret}'
-  is equivalent to 'rev{caret}1').  As a special rule,
-  'rev{caret}0' means the commit itself and is used when 'rev' is the
-  object name of a tag object that refers to a commit object.
-
-* A suffix '{tilde}<n>' to a revision parameter means the commit
-  object that is the <n>th generation grand-parent of the named
-  commit object, following only the first parent.  I.e. rev~3 is
-  equivalent to rev{caret}{caret}{caret} which is equivalent to
-  rev{caret}1{caret}1{caret}1.  See below for a illustration of
-  the usage of this form.
-
-* A suffix '{caret}' followed by an object type name enclosed in
-  brace pair (e.g. `v0.99.8{caret}\{commit\}`) means the object
-  could be a tag, and dereference the tag recursively until an
-  object of that type is found or the object cannot be
-  dereferenced anymore (in which case, barf).  `rev{caret}0`
-  introduced earlier is a short-hand for `rev{caret}\{commit\}`.
-
-* A suffix '{caret}' followed by an empty brace pair
-  (e.g. `v0.99.8{caret}\{\}`) means the object could be a tag,
-  and dereference the tag recursively until a non-tag object is
-  found.
-
-* A colon, followed by a slash, followed by a text: this names
-  a commit whose commit message starts with the specified text.
-  This name returns the youngest matching commit which is
-  reachable from any ref.  If the commit message starts with a
-  '!', you have to repeat that;  the special sequence ':/!',
-  followed by something else than '!' is reserved for now.
-
-* A suffix ':' followed by a path; this names the blob or tree
-  at the given path in the tree-ish object named by the part
-  before the colon.
-
-* A colon, optionally followed by a stage number (0 to 3) and a
-  colon, followed by a path; this names a blob object in the
-  index at the given path.  Missing stage number (and the colon
-  that follows it) names a stage 0 entry. During a merge, stage
-  1 is the common ancestor, stage 2 is the target branch's version
-  (typically the current branch), and stage 3 is the version from
-  the branch being merged.

-SPECIFYING RANGES
------------------
-
-History traversing commands such as 'git-log' operate on a set
-of commits, not just a single commit.  To these commands,
-specifying a single revision with the notation described in the
-previous section means the set of commits reachable from that
-commit, following the commit ancestry chain.
-
-To exclude commits reachable from a commit, a prefix `{caret}`
-notation is used.  E.g. `{caret}r1 r2` means commits reachable
-from `r2` but exclude the ones reachable from `r1`.
-
-This set operation appears so often that there is a shorthand
-for it.  When you have two commits `r1` and `r2` (named according
-to the syntax explained in SPECIFYING REVISIONS above), you can ask
-for commits that are reachable from r2 excluding those that are reachable
-from r1 by `{caret}r1 r2` and it can be written as `r1..r2`.
-
-A similar notation `r1\...r2` is called symmetric difference
-of `r1` and `r2` and is defined as
-`r1 r2 --not $(git merge-base --all r1 r2)`.
-It is the set of commits that are reachable from either one of
-`r1` or `r2` but not from both.
-
-Two other shorthands for naming a set that is formed by a commit
-and its parent commits exist.  The `r1{caret}@` notation means all
-parents of `r1`.  `r1{caret}!` includes commit `r1` but excludes
-all of its parents.
-
-Here are a handful of examples:
-
-   D                G H D
-   D F              G H I J D F
-   ^G D             H D
-   ^D B             E I J F B
-   B...C            G H D E B C
-   ^D B C           E I J F B C
-   C^@              I J F
-   F^! D            G H D F

+REMOVING FILES THAT HAVE DISAPPEARED FROM THE FILESYSTEM
+--------------------------------------------------------
+There is no option for `git rm` to remove from the index only
+the paths that have disappeared from the filesystem. However,
+depending on the use case, there are several ways that can be
+done.
+
+Using ``git commit -a''
+~~~~~~~~~~~~~~~~~~~~~~~
+If you intend that your next commit should record all modifications
+of tracked files in the working tree and record all removals of
+files that have been removed from the working tree with `rm`
+(as opposed to `git rm`), use `git commit -a`, as it will
+automatically notice and record all removals.  You can also have a
+similar effect without committing by using `git add -u`.
+
+Using ``git add -A''
+~~~~~~~~~~~~~~~~~~~~
+When accepting a new code drop for a vendor branch, you probably
+want to record both the removal of paths and additions of new paths
+as well as modifications of existing paths.
+
+Typically you would first remove all tracked files from the working
+tree using this command:
+
+----------------
+git ls-files -z | xargs -0 rm -f
+----------------
+
+and then untar the new code in the working tree. Alternately
+you could 'rsync' the changes into the working tree.
+
+After that, the easiest way to record all removals, additions, and
+modifications in the working tree is:
+
+----------------
+git add -A
+----------------
+
+See linkgit:git-add[1].
+
+Other ways
+~~~~~~~~~~
+If all you really want to do is to remove from the index the files
+that are no longer present in the working tree (perhaps because
+your working tree is dirty so that you cannot use `git commit -a`),
+use the following command:
+
+----------------
+git diff --name-only --diff-filter=D -z | xargs -0 git rm --cached
+----------------
+
+SUBMODULES
+----------
+Only submodules using a gitfile (which means they were cloned
+with a Git version 1.7.8 or newer) will be removed from the work
+tree, as their repository lives inside the .git directory of the
+superproject. If a submodule (or one of those nested inside it)
+still uses a .git directory, `git rm` will fail - no matter if forced
+or not - to protect the submodule's history. If it exists the
+submodule.<name> section in the linkgit:gitmodules[5] file will also
+be removed and that file will be staged (unless --cached or -n are used).
+
+A submodule is considered up-to-date when the HEAD is the same as
+recorded in the index, no tracked files are modified and no untracked
+files that aren't ignored are present in the submodules work tree.
+Ignored files are deemed expendable and won't stop a submodule's work
+tree from being removed.
+
+If you only want to remove the local checkout of a submodule from your
+work tree without committing the removal,
+use linkgit:git-submodule[1] `deinit` instead.
+
 EXAMPLES
 --------
-git rm Documentation/\\*.txt::
-	Removes all `\*.txt` files from the index that are under the
+`git rm Documentation/\*.txt`::
+	Removes all `*.txt` files from the index that are under the
 	`Documentation` directory and any of its subdirectories.
 +
-Note that the asterisk `\*` is quoted from the shell in this
-example; this lets git, and not the shell, expand the pathnames
+Note that the asterisk `*` is quoted from the shell in this
+example; this lets Git, and not the shell, expand the pathnames
 of files and subdirectories under the `Documentation/` directory.
 
-git rm -f git-*.sh::
+`git rm -f git-*.sh`::
 	Because this example lets the shell expand the asterisk
 	(i.e. you are listing the files explicitly), it
 	does not remove `subdir/git-foo.sh`.
 
+BUGS
+----
+Each time a superproject update removes a populated submodule
+(e.g. when switching between commits before and after the removal) a
+stale submodule checkout will remain in the old location. Removing the
+old directory is only safe when it uses a gitfile, as otherwise the
+history of the submodule will be deleted too. This step will be
+obsolete when recursive submodule update has been implemented.

 DESCRIPTION
 -----------
-This is meant to be used as a login shell for SSH accounts you want
-to restrict to GIT pull/push access only. It permits execution only
-of server-side GIT commands implementing the pull/push functionality.
-The commands can be executed only by the '-c' option; the shell is not
-interactive.
-
-Currently, only four commands are permitted to be called, 'git-receive-pack'
-'git-upload-pack' and 'git-upload-archive' with a single required argument, or
-'cvs server' (to invoke 'git-cvsserver').

-Documentation by Petr Baudis and the git-list <git@vger.kernel.org>.
+
+This is a login shell for SSH accounts to provide restricted Git access.
+It permits execution only of server-side Git commands implementing the
+pull/push functionality, plus custom commands present in a subdirectory
+named `git-shell-commands` in the user's home directory.
+
+COMMANDS
+--------
+
+'git shell' accepts the following commands after the '-c' option:
+
+'git receive-pack <argument>'::
+'git upload-pack <argument>'::
+'git upload-archive <argument>'::
+	Call the corresponding server-side command to support
+	the client's 'git push', 'git fetch', or 'git archive --remote'
+	request.
+'cvs server'::
+	Imitate a CVS server.  See linkgit:git-cvsserver[1].
+
+If a `~/git-shell-commands` directory is present, 'git shell' will
+also handle other, custom commands by running
+"`git-shell-commands/<command> <arguments>`" from the user's home
+directory.
+
+INTERACTIVE USE
+---------------
+
+By default, the commands above can be executed only with the '-c'
+option; the shell is not interactive.
+
+If a `~/git-shell-commands` directory is present, 'git shell'
+can also be run interactively (with no arguments).  If a `help`
+command is present in the `git-shell-commands` directory, it is
+run to provide the user with an overview of allowed actions.  Then a
+"git> " prompt is presented at which one can enter any of the
+commands from the `git-shell-commands` directory, or `exit` to close
+the connection.
+
+Generally this mode is used as an administrative interface to allow
+users to list repositories they have access to, create, delete, or
+rename repositories, or change repository descriptions and
+permissions.
+
+If a `no-interactive-login` command exists, then it is run and the
+interactive shell is aborted.
+
+EXAMPLE
+-------
+
+To disable interactive logins, displaying a greeting instead:
+
+----------------
+$ chsh -s /usr/bin/git-shell
+$ mkdir $HOME/git-shell-commands
+$ cat >$HOME/git-shell-commands/no-interactive-login <<\EOF
+#!/bin/sh
+printf '%s\n' "Hi $USER! You've successfully authenticated, but I do not"
+printf '%s\n' "provide interactive shell access."
+exit 128

++
+The mode parameter is optional (defaults to 'all'), and is used to
+specify the handling of untracked files.
++
+The possible options are:
++
+	- 'no'     - Show no untracked files.
+	- 'normal' - Shows untracked files and directories.
+	- 'all'    - Also shows individual files in untracked directories.
++
+When `-u` option is not used, untracked files and directories are
+shown (i.e. the same as specifying `normal`), to help you avoid
+forgetting to add newly created files.  Because it takes extra work
+to find untracked files in the filesystem, this mode may take some
+time in a large working tree.  You can use `no` to have `git status`
+return more quickly without showing untracked files.
++
+The default can be changed using the status.showUntrackedFiles
+configuration variable documented in linkgit:git-config[1].

+--ignore-submodules[=<when>]::
+	Ignore changes to submodules when looking for changes. <when> can be

+	'ignore' option in linkgit:git-config[1] or linkgit:gitmodules[5]. When
+	"untracked" is used submodules are not considered dirty when they only
+	contain untracked content (but they are still scanned for modified

+	the behavior before 1.7.0). Using "all" hides all changes to submodules
+	(and suppresses the output of submodule summaries when the config option

+
+--ignored::
+	Show ignored files as well.

+-z::
+	Terminate entries with NUL, instead of LF.  This implies

+Short Format
+~~~~~~~~~~~~
+
+In the short-format, the status of each path is shown as
+
+	XY PATH1 -> PATH2
+
+where `PATH1` is the path in the `HEAD`, and the " `-> PATH2`" part is
+shown only when `PATH1` corresponds to a different path in the
+index/worktree (i.e. the file is renamed). The `XY` is a two-letter
+status code.
+
+The fields (including the `->`) are separated from each other by a
+single space. If a filename contains whitespace or other nonprintable
+characters, that field will be quoted in the manner of a C string
+literal: surrounded by ASCII double quote (34) characters, and with
+interior special characters backslash-escaped.
+
+For paths with merge conflicts, `X` and `Y` show the modification
+states of each side of the merge. For paths that do not have merge
+conflicts, `X` shows the status of the index, and `Y` shows the status
+of the work tree.  For untracked paths, `XY` are `??`.  Other status
+codes can be interpreted as follows:
+
+* ' ' = unmodified
+* 'M' = modified
+* 'A' = added
+* 'D' = deleted
+* 'R' = renamed
+* 'C' = copied
+* 'U' = updated but unmerged

+Porcelain Format
+~~~~~~~~~~~~~~~~
+
+The porcelain format is similar to the short format, but is guaranteed
+not to change in a backwards-incompatible way between Git versions or
+based on user configuration. This makes it ideal for parsing by scripts.
+The description of the short format above also describes the porcelain
+format, with a few exceptions:
+
+1. The user's color.status configuration is not respected; color will
+   always be off.
+
+2. The user's status.relativePaths configuration is not respected; paths
+   shown will always be relative to the repository root.
+
+There is also an alternate -z format recommended for machine parsing. In
+that format, the status field is the same, but some other things
+change.  First, the '\->' is omitted from rename entries and the field
+order is reversed (e.g 'from \-> to' becomes 'to from'). Second, a NUL
+(ASCII 0) follows each filename, replacing space as a field separator
+and the terminating newline (but a space still separates the status
+field from the first filename).  Third, filenames containing special
+characters are not specially formatted; no quoting or
+backslash-escaping is performed.

-'git stripspace' [-s | --strip-comments] < <stream>
+[verse]
+'git stripspace' [-s | --strip-comments] < input
+'git stripspace' [-c | --comment-lines] < input
 
 DESCRIPTION
 -----------
-Remove multiple empty lines, and empty lines at beginning and end.
+
+Clean the input in the manner used by Git for text such as commit
+messages, notes, tags and branch descriptions.
+
+With no arguments, this will:
+
+- remove trailing whitespace from all lines
+- collapse multiple consecutive empty lines into one empty line
+- remove empty lines from the beginning and end of the input
+- add a missing '\n' to the last line if necessary.
+
+In the case where the input consists entirely of whitespace characters, no
+output will be produced.
+
+*NOTE*: This is intended for cleaning metadata, prefer the `--whitespace=fix`
+mode of linkgit:git-apply[1] for correcting whitespace of patches or files in
+the repository.
 
 OPTIONS
 -------
 -s::
 --strip-comments::
-	In addition to empty lines, also strip lines starting with '#'.
+	Skip and remove all lines starting with comment character (default '#').

+HANDLING OF SVN BRANCHES
+------------------------
+If 'git svn' is configured to fetch branches (and --follow-branches
+is in effect), it sometimes creates multiple Git branches for one
+SVN branch, where the additional branches have names of the form
+'branchname@nnn' (with nnn an SVN revision number).  These additional
+branches are created if 'git svn' cannot find a parent commit for the
+first commit in an SVN branch, to connect the branch to the history of
+the other branches.
+
+Normally, the first commit in an SVN branch consists
+of a copy operation. 'git svn' will read this commit to get the SVN
+revision the branch was created from. It will then try to find the
+Git commit that corresponds to this SVN revision, and use that as the
+parent of the branch. However, it is possible that there is no suitable
+Git commit to serve as parent.  This will happen, among other reasons,
+if the SVN branch is a copy of a revision that was not fetched by 'git
+svn' (e.g. because it is an old revision that was skipped with
+'--revision'), or if in SVN a directory was copied that is not tracked
+by 'git svn' (such as a branch that is not tracked at all, or a
+subdirectory of a tracked branch). In these cases, 'git svn' will still
+create a Git branch, but instead of using an existing Git commit as the
+parent of the branch, it will read the SVN history of the directory the
+branch was copied from and create appropriate Git commits.  This is
+indicated by the message "Initializing parent: <branchname>".
+
+Additionally, it will create a special branch named
+'<branchname>@<SVN-Revision>', where <SVN-Revision> is the SVN revision
+number the branch was copied from.  This branch will point to the newly
+created parent commit of the branch.  If in SVN the branch was deleted
+and later recreated from a different version, there will be multiple
+such branches with an '@'.
+
+Note that this may mean that multiple Git commits are created for a
+single SVN revision.
+
+An example: in an SVN repository with a standard
+trunk/tags/branches layout, a directory trunk/sub is created in r.100.
+In r.200, trunk/sub is branched by copying it to branches/. 'git svn
+clone -s' will then create a branch 'sub'. It will also create new Git
+commits for r.100 through r.199 and use these as the history of branch
+'sub'. Thus there will be two Git commits for each revision from r.100
+to r.199 (one containing trunk/, one containing trunk/sub/). Finally,
+it will create a branch 'sub@200' pointing to the new parent commit of
+branch 'sub' (i.e. the commit for r.200 and trunk/sub/).

-NAME
-----
-git-tar-tree - Create a tar archive of the files in the named tree object
-
-
-SYNOPSIS
---------
-'git tar-tree' [--remote=<repo>] <tree-ish> [ <base> ]
-
-DESCRIPTION
------------
-THIS COMMAND IS DEPRECATED.  Use 'git-archive' with `--format=tar`
-option instead (and move the <base> argument to `--prefix=base/`).
-
-Creates a tar archive containing the tree structure for the named tree.
-When <base> is specified it is added as a leading path to the files in the
-generated tar archive.
-
-'git-tar-tree' behaves differently when given a tree ID versus when given
-a commit ID or tag ID.  In the first case the current time is used as
-modification time of each file in the archive.  In the latter case the
-commit time as recorded in the referenced commit object is used instead.
-Additionally the commit ID is stored in a global extended pax header.
-It can be extracted using 'git-get-tar-commit-id'.
-
-OPTIONS
--------
-
-<tree-ish>::
-	The tree or commit to produce tar archive for.  If it is
-	the object name of a commit object.
-
-<base>::
-	Leading path to the files in the resulting tar archive.
-
---remote=<repo>::
-	Instead of making a tar archive from local repository,
-	retrieve a tar archive from a remote repository.
-
-CONFIGURATION
--------------
-
-tar.umask::
-	This variable can be used to restrict the permission bits of
-	tar archive entries.  The default is 0002, which turns off the
-	world write bit.  The special value "user" indicates that the
-	archiving user's umask will be used instead.  See umask(2) for
-	details.
-
-EXAMPLES
---------
-git tar-tree HEAD junk | (cd /var/tmp/ && tar xf -)::
-
-	Create a tar archive that contains the contents of the
-	latest commit on the current branch, and extracts it in
-	`/var/tmp/junk` directory.
-
-git tar-tree v1.4.0 git-1.4.0 | gzip >git-1.4.0.tar.gz::
-
-	Create a tarball for v1.4.0 release.
-
-git tar-tree v1.4.0{caret}\{tree\} git-1.4.0 | gzip >git-1.4.0.tar.gz::
-
-	Create a tarball for v1.4.0 release, but without a
-	global extended pax header.
-
-git tar-tree --remote=example.com:git.git v1.4.0 >git-1.4.0.tar::
-
-	Get a tarball v1.4.0 from example.com.
-
-git tar-tree HEAD:Documentation/ git-docs > git-1.4.0-docs.tar::

+SECURITY
+--------
+
+In order to protect the privacy of objects that have been removed from
+history but may not yet have been pruned, `git-upload-archive` avoids
+serving archives for commits and trees that are not reachable from the
+repository's refs.  However, because calculating object reachability is
+computationally expensive, `git-upload-archive` implements a stricter
+but easier-to-check set of rules:
+
+  1. Clients may request a commit or tree that is pointed to directly by
+     a ref. E.g., `git archive --remote=origin v1.0`.
+
+  2. Clients may request a sub-tree within a commit or tree using the
+     `ref:path` syntax. E.g., `git archive --remote=origin v1.0:Documentation`.
+
+  3. Clients may _not_ use other sha1 expressions, even if the end
+     result is reachable. E.g., neither a relative commit like `master^`
+     nor a literal sha1 like `abcd1234` is allowed, even if the result
+     is reachable from the refs.
+
+Note that rule 3 disallows many cases that do not have any privacy
+implications. These rules are subject to change in future versions of
+git, and the server accessed by `git archive --remote` may or may not
+follow these exact rules.
+
+If the config option `uploadArchive.allowUnreachable` is true, these
+rules are ignored, and clients may use arbitrary sha1 expressions.
+This is useful if you do not care about the privacy of unreachable
+objects, or if your object database is already publicly available for
+access via non-smart-http.

 DESCRIPTION
 -----------
-Shows commit logs and diff output each commit introduces.  The

-This manual page describes only the most frequently used options.

+New users are encouraged to use linkgit:git-log[1] instead.  The

-OPTIONS
--------
--p::
-	Show textual diffs, instead of the git internal diff
-	output format that is useful only to tell the changed
-	paths and their nature of changes.
+The command is kept primarily for historical reasons; fingers of
+many people who learned Git long before `git log` was invented by
+reading Linux kernel mailing list are trained to type it.
 
--<n>::
-	Limit output to <n> commits.

-	Show git internal diff output, but for the whole tree,

+
+Backwards compatibility with `crlf` attribute
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+For backwards compatibility, the `crlf` attribute is interpreted as
+follows:
+
+------------------------
+crlf		text
+-crlf		-text
+crlf=input	eol=lf
+------------------------
+
+End-of-line conversion
+^^^^^^^^^^^^^^^^^^^^^^
 
-If the configuration variable `core.autocrlf` is false, no
-conversion is done.
+While Git normally leaves file contents alone, it can be configured to
+normalize line endings to LF in the repository and, optionally, to
+convert them to CRLF when files are checked out.
 
-When `core.autocrlf` is true, it means that the platform wants
-CRLF line endings for files in the working tree, and you want to
-convert them back to the normal LF line endings when checking
-in to the repository.
+Here is an example that will make Git normalize .txt, .vcproj and .sh
+files, ensure that .vcproj files have CRLF and .sh files have LF in
+the working directory, and prevent .jpg files from being normalized
+regardless of their content.
+
+------------------------
+*.txt		text
+*.vcproj	eol=crlf
+*.sh		eol=lf
+*.jpg		-text
+------------------------
+
+Other source code management systems normalize all text files in their
+repositories, and there are two ways to enable similar automatic
+normalization in Git.
+
+If you simply want to have CRLF line endings in your working directory
+regardless of the repository you are working with, you can set the
+config variable "core.autocrlf" without changing any attributes.
+
+------------------------
+[core]
+	autocrlf = true
+------------------------
+
+This does not force normalization of all text files, but does ensure
+that text files that you introduce to the repository have their line
+endings normalized to LF when they are added, and that files that are
+already normalized in the repository stay normalized.
+
+If you want to interoperate with a source code management system that
+enforces end-of-line normalization, or you simply want all text files
+in your repository to be normalized, you should instead set the `text`
+attribute to "auto" for _all_ files.
+
+------------------------
+*	text=auto
+------------------------
 
-When `core.autocrlf` is set to "input", line endings are
-converted to LF upon checkin, but there is no conversion done
-upon checkout.
+This ensures that all files that Git considers to be text will have
+normalized (LF) line endings in the repository.  The `core.eol`
+configuration variable controls which line endings Git will use for
+normalized files in your working directory; the default is to use the
+native line ending for your platform, or CRLF if `core.autocrlf` is
+set.
+
+NOTE: When `text=auto` normalization is enabled in an existing
+repository, any text files containing CRLFs should be normalized.  If
+they are not they will be normalized the next time someone tries to
+change them, causing unfortunate misattribution.  From a clean working
+directory:
+
+-------------------------------------------------
+$ echo "* text=auto" >>.gitattributes
+$ rm .git/index     # Remove the index to force Git to
+$ git reset         # re-scan the working directory
+$ git status        # Show files that will be normalized
+$ git add -u
+$ git add .gitattributes
+$ git commit -m "Introduce end-of-line normalization"
+-------------------------------------------------
+
+If any files that should not be normalized show up in 'git status',
+unset their `text` attribute before running 'git add -u'.

-A missing filter driver definition in the config is not an error

+One use of the content filtering is to massage the content into a shape

+For this mode of operation, the key phrase here is "more convenient" and
+not "turning something unusable into usable".  In other words, the intent
+is that if someone unsets the filter driver definition, or does not have
+the appropriate filter program, the project should still be usable.
+
+Another use of the content filtering is to store the content that cannot
+be directly used in the repository (e.g. a UUID that refers to the true
+content stored outside Git, or an encrypted content) and turn it into a
+usable form upon checkout (e.g. download the external content, or decrypt
+the encrypted content).
+
+These two filters behave differently, and by default, a filter is taken as
+the former, massaging the contents into more convenient shape.  A missing
+filter driver definition in the config, or a filter driver that exits with
+a non-zero status, is not an error but makes the filter a no-op passthru.
+
+You can declare that a filter turns a content that by itself is unusable
+into a usable content by setting the filter.<driver>.required configuration
+variable to `true`.
+
+For example, in .gitattributes, you would assign the `filter`
+attribute for paths.
+
+------------------------

+------------------------
+
+Then you would define a "filter.indent.clean" and "filter.indent.smudge"
+configuration in your .git/config to specify a pair of commands to
+modify the contents of C programs when the source files are checked
+in ("clean" is run) and checked out (no change is made because the
+command is "cat").
+
+------------------------
+[filter "indent"]
+	clean = indent
+	smudge = cat
+------------------------
+
+For best results, `clean` should not alter its output further if it is
+run twice ("clean->clean" should be equivalent to "clean"), and
+multiple `smudge` commands should not alter `clean`'s output
+("smudge->smudge->clean" should be equivalent to "clean").  See the
+section on merging below.
+
+The "indent" filter is well-behaved in this regard: it will not modify
+input that is already correctly indented.  In this case, the lack of a
+smudge filter means that the clean filter _must_ accept its own output
+without modifying it.
+
+If a filter _must_ succeed in order to make the stored contents usable,

+
+If you have added attributes to a file that cause the canonical

+where the attribute is not in place would normally cause merge

+
+To prevent these unnecessary merge conflicts, Git can be told to run a

+configuration variable.  This prevents changes caused by check-in
+conversion from causing spurious merge conflicts when a converted file
+is merged with an unconverted file.

 should generate it separately and send it as a comment _in
 addition to_ the usual binary diff that you might send.
 
+Because text conversion can be slow, especially when doing a
+large number of them with `git log -p`, Git provides a mechanism
+to cache the output and use it in future diffs.  To enable
+caching, set the "cachetextconv" variable in your diff driver's
+config. For example:
+
+------------------------
+[diff "jpg"]
+	textconv = exif
+	cachetextconv = true
+------------------------
+
+This will cache the result of running "exif" on each blob
+indefinitely. If you change the textconv config variable for a
+diff driver, Git will automatically invalidate the cache entries
+and re-run the textconv filter. If you want to invalidate the
+cache manually (e.g., because your version of "exif" was updated
+and now produces better output), you can remove the cache
+manually with `git update-ref -d refs/notes/textconv/jpg` (where
+"jpg" is the name of the diff driver, as in the example above).
+
+Choosing textconv versus external diff
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you want to show differences between binary or specially-formatted
+blobs in your repository, you can choose to use either an external diff
+command, or to use textconv to convert them to a diff-able text format.
+Which method you choose depends on your exact situation.
+
+The advantage of using an external diff command is flexibility. You are
+not bound to find line-oriented changes, nor is it necessary for the
+output to resemble unified diff. You are free to locate and report
+changes in the most appropriate way for your data format.
+
+A textconv, by comparison, is much more limiting. You provide a
+transformation of the data into a line-oriented text format, and Git
+uses its regular diff tools to generate the output. There are several
+advantages to choosing this method:
+
+1. Ease of use. It is often much simpler to write a binary to text
+   transformation than it is to perform your own diff. In many cases,
+   existing programs can be used as textconv filters (e.g., exif,
+   odt2txt).
+
+2. Git diff features. By performing only the transformation step
+   yourself, you can still utilize many of Git's diff features,
+   including colorization, word-diff, and combined diffs for merges.
+
+3. Caching. Textconv caching can speed up repeated diffs, such as those
+   you might trigger by running `git log -p`.
+
+
+Marking files as binary
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Git usually guesses correctly whether a blob contains text or binary
+data by examining the beginning of the contents. However, sometimes you
+may want to override its decision, either because a blob contains binary
+data later in the file, or because the content, while technically
+composed of text characters, is opaque to a human reader. For example,
+many postscript files contain only ASCII characters, but produce noisy
+and meaningless diffs.
+
+The simplest way to mark a file as binary is to unset the diff
+attribute in the `.gitattributes` file:
+
+------------------------
+*.ps -diff
+------------------------
+
+This will cause Git to generate `Binary files differ` (or a binary
+patch, if binary patches are enabled) instead of a regular diff.
+
+However, one may also want to specify other diff driver attributes. For
+example, you might want to use `textconv` to convert postscript files to
+an ASCII representation for human viewing, but otherwise treat them as
+binary files. You cannot specify both `-diff` and `diff=ps` attributes.
+The solution is to use the `diff.*.binary` config option:
+
+------------------------
+[diff "ps"]
+  textconv = ps2ascii
+  binary = true

+=================
+
+NAME
+----
+gitcredentials - providing usernames and passwords to Git
+
+SYNOPSIS
+--------
+------------------
+git config credential.https://example.com.username myusername
+git config credential.helper "$helper $options"
+------------------
+
+DESCRIPTION
+-----------
+
+Git will sometimes need credentials from the user in order to perform
+operations; for example, it may need to ask for a username and password
+in order to access a remote repository over HTTP. This manual describes
+the mechanisms Git uses to request these credentials, as well as some
+features to avoid inputting these credentials repeatedly.
+
+REQUESTING CREDENTIALS
+----------------------
+
+Without any credential helpers defined, Git will try the following
+strategies to ask the user for usernames and passwords:
+
+1. If the `GIT_ASKPASS` environment variable is set, the program
+   specified by the variable is invoked. A suitable prompt is provided
+   to the program on the command line, and the user's input is read
+   from its standard output.
+
+2. Otherwise, if the `core.askpass` configuration variable is set, its
+   value is used as above.
+
+3. Otherwise, if the `SSH_ASKPASS` environment variable is set, its
+   value is used as above.
+
+4. Otherwise, the user is prompted on the terminal.
+
+AVOIDING REPETITION
+-------------------
+
+It can be cumbersome to input the same credentials over and over.  Git
+provides two methods to reduce this annoyance:
+
+1. Static configuration of usernames for a given authentication context.
+
+2. Credential helpers to cache or store passwords, or to interact with
+   a system password wallet or keychain.
+
+The first is simple and appropriate if you do not have secure storage available
+for a password. It is generally configured by adding this to your config:
+
+---------------------------------------
+[credential "https://example.com"]
+	username = me
+---------------------------------------
+
+Credential helpers, on the other hand, are external programs from which Git can
+request both usernames and passwords; they typically interface with secure
+storage provided by the OS or other programs.
+
+To use a helper, you must first select one to use. Git currently
+includes the following helpers:
+
+cache::
+
+	Cache credentials in memory for a short period of time. See
+	linkgit:git-credential-cache[1] for details.
+
+store::
+
+	Store credentials indefinitely on disk. See
+	linkgit:git-credential-store[1] for details.
+
+You may also have third-party helpers installed; search for
+`credential-*` in the output of `git help -a`, and consult the
+documentation of individual helpers.  Once you have selected a helper,
+you can tell Git to use it by putting its name into the
+credential.helper variable.
+
+1. Find a helper.
++
+-------------------------------------------
+$ git help -a | grep credential-
+credential-foo
+-------------------------------------------
+
+2. Read its description.
++
+-------------------------------------------
+$ git help credential-foo
+-------------------------------------------
+
+3. Tell Git to use it.
++
+-------------------------------------------
+$ git config --global credential.helper foo
+-------------------------------------------
+
+If there are multiple instances of the `credential.helper` configuration
+variable, each helper will be tried in turn, and may provide a username,
+password, or nothing. Once Git has acquired both a username and a
+password, no more helpers will be tried.
+
+
+CREDENTIAL CONTEXTS
+-------------------
+
+Git considers each credential to have a context defined by a URL. This context
+is used to look up context-specific configuration, and is passed to any
+helpers, which may use it as an index into secure storage.
+
+For instance, imagine we are accessing `https://example.com/foo.git`. When Git
+looks into a config file to see if a section matches this context, it will
+consider the two a match if the context is a more-specific subset of the
+pattern in the config file. For example, if you have this in your config file:
+
+--------------------------------------
+[credential "https://example.com"]
+	username = foo
+--------------------------------------
+
+then we will match: both protocols are the same, both hosts are the same, and
+the "pattern" URL does not care about the path component at all. However, this
+context would not match:
+
+--------------------------------------
+[credential "https://kernel.org"]
+	username = foo
+--------------------------------------
+
+because the hostnames differ. Nor would it match `foo.example.com`; Git
+compares hostnames exactly, without considering whether two hosts are part of
+the same domain. Likewise, a config entry for `http://example.com` would not
+match: Git compares the protocols exactly.
+
+
+CONFIGURATION OPTIONS
+---------------------
+
+Options for a credential context can be configured either in
+`credential.*` (which applies to all credentials), or
+`credential.<url>.*`, where <url> matches the context as described
+above.
+
+The following options are available in either location:
+
+helper::
+
+	The name of an external credential helper, and any associated options.
+	If the helper name is not an absolute path, then the string `git
+	credential-` is prepended. The resulting string is executed by the
+	shell (so, for example, setting this to `foo --option=bar` will execute
+	`git credential-foo --option=bar` via the shell. See the manual of
+	specific helpers for examples of their use.
+
+username::
+
+	A default username, if one is not provided in the URL.
+
+useHttpPath::
+
+	By default, Git does not consider the "path" component of an http URL
+	to be worth matching via external helpers. This means that a credential
+	stored for `https://example.com/foo.git` will also be used for
+	`https://example.com/bar.git`. If you do want to distinguish these
+	cases, set this option to `true`.
+
+
+CUSTOM HELPERS
+--------------
+
+You can write your own custom helpers to interface with any system in
+which you keep credentials. See the documentation for Git's
+link:technical/api-credentials.html[credentials API] for details.

+NAME
+----
+giteveryday - A useful minimum set of commands for Everyday Git
+
+SYNOPSIS
+--------
+
+Everyday Git With 20 Commands Or So
+
+DESCRIPTION
+-----------
+
+Git users can broadly be grouped into four categories for the purposes of
+describing here a small set of useful command for everyday Git.
+
+*	<<STANDALONE,Individual Developer (Standalone)>> commands are essential
+	for anybody who makes a commit, even for somebody who works alone.
+
+*	If you work with other people, you will need commands listed in
+	the <<PARTICIPANT,Individual Developer (Participant)>> section as well.
+
+*	People who play the <<INTEGRATOR,Integrator>> role need to learn some
+	more commands in addition to the above.
+
+*	<<ADMINISTRATION,Repository Administration>> commands are for system
+	administrators who are responsible for the care and feeding
+	of Git repositories.
+
+
+Individual Developer (Standalone)[[STANDALONE]]
+-----------------------------------------------
+
+A standalone individual developer does not exchange patches with
+other people, and works alone in a single repository, using the
+following commands.
+
+  * linkgit:git-init[1] to create a new repository.
+
+  * linkgit:git-log[1] to see what happened.
+
+  * linkgit:git-checkout[1] and linkgit:git-branch[1] to switch
+    branches.
+
+  * linkgit:git-add[1] to manage the index file.
+
+  * linkgit:git-diff[1] and linkgit:git-status[1] to see what
+    you are in the middle of doing.
+
+  * linkgit:git-commit[1] to advance the current branch.
+
+  * linkgit:git-reset[1] and linkgit:git-checkout[1] (with
+    pathname parameters) to undo changes.
+
+  * linkgit:git-merge[1] to merge between local branches.
+
+  * linkgit:git-rebase[1] to maintain topic branches.
+
+  * linkgit:git-tag[1] to mark a known point.
+
+Examples
+~~~~~~~~
+
+Use a tarball as a starting point for a new repository.::
++
+------------
+$ tar zxf frotz.tar.gz
+$ cd frotz
+$ git init
+$ git add . <1>
+$ git commit -m "import of frotz source tree."
+$ git tag v2.43 <2>
+------------
++
+<1> add everything under the current directory.
+<2> make a lightweight, unannotated tag.
+
+Create a topic branch and develop.::
++
+------------
+$ git checkout -b alsa-audio <1>
+$ edit/compile/test
+$ git checkout -- curses/ux_audio_oss.c <2>
+$ git add curses/ux_audio_alsa.c <3>
+$ edit/compile/test
+$ git diff HEAD <4>
+$ git commit -a -s <5>
+$ edit/compile/test
+$ git diff HEAD^ <6>
+$ git commit -a --amend <7>
+$ git checkout master <8>
+$ git merge alsa-audio <9>
+$ git log --since='3 days ago' <10>
+$ git log v2.43.. curses/ <11>
+------------
++
+<1> create a new topic branch.
+<2> revert your botched changes in `curses/ux_audio_oss.c`.
+<3> you need to tell Git if you added a new file; removal and
+modification will be caught if you do `git commit -a` later.
+<4> to see what changes you are committing.
+<5> commit everything, as you have tested, with your sign-off.
+<6> look at all your changes including the previous commit.
+<7> amend the previous commit, adding all your new changes,
+using your original message.
+<8> switch to the master branch.
+<9> merge a topic branch into your master branch.
+<10> review commit logs; other forms to limit output can be
+combined and include `-10` (to show up to 10 commits),
+`--until=2005-12-10`, etc.
+<11> view only the changes that touch what's in `curses/`
+directory, since `v2.43` tag.
+
+
+Individual Developer (Participant)[[PARTICIPANT]]
+-------------------------------------------------
+
+A developer working as a participant in a group project needs to
+learn how to communicate with others, and uses these commands in
+addition to the ones needed by a standalone developer.
+
+  * linkgit:git-clone[1] from the upstream to prime your local
+    repository.
+
+  * linkgit:git-pull[1] and linkgit:git-fetch[1] from "origin"
+    to keep up-to-date with the upstream.
+
+  * linkgit:git-push[1] to shared repository, if you adopt CVS
+    style shared repository workflow.
+
+  * linkgit:git-format-patch[1] to prepare e-mail submission, if
+    you adopt Linux kernel-style public forum workflow.
+
+  * linkgit:git-send-email[1] to send your e-mail submission without
+    corruption by your MUA.
+
+  * linkgit:git-request-pull[1] to create a summary of changes
+    for your upstream to pull.
+
+
+Examples
+~~~~~~~~
+
+Clone the upstream and work on it.  Feed changes to upstream.::
++
+------------
+$ git clone git://git.kernel.org/pub/scm/.../torvalds/linux-2.6 my2.6
+$ cd my2.6
+$ git checkout -b mine master <1>
+$ edit/compile/test; git commit -a -s <2>
+$ git format-patch master <3>
+$ git send-email --to="person <email@example.com>" 00*.patch <4>
+$ git checkout master <5>
+$ git pull <6>
+$ git log -p ORIG_HEAD.. arch/i386 include/asm-i386 <7>
+$ git ls-remote --heads http://git.kernel.org/.../jgarzik/libata-dev.git <8>
+$ git pull git://git.kernel.org/pub/.../jgarzik/libata-dev.git ALL <9>
+$ git reset --hard ORIG_HEAD <10>
+$ git gc <11>
+------------
++
+<1> checkout a new branch `mine` from master.
+<2> repeat as needed.
+<3> extract patches from your branch, relative to master,
+<4> and email them.
+<5> return to `master`, ready to see what's new
+<6> `git pull` fetches from `origin` by default and merges into the
+current branch.
+<7> immediately after pulling, look at the changes done upstream
+since last time we checked, only in the
+area we are interested in.
+<8> check the branch names in an external repository (if not known).
+<9> fetch from a specific branch `ALL` from a specific repository
+and merge it.
+<10> revert the pull.
+<11> garbage collect leftover objects from reverted pull.
+
+
+Push into another repository.::
++
+------------
+satellite$ git clone mothership:frotz frotz <1>
+satellite$ cd frotz
+satellite$ git config --get-regexp '^(remote|branch)\.' <2>
+remote.origin.url mothership:frotz

+satellite$ edit/compile/test/commit
+satellite$ git push origin <4>
+
+mothership$ cd frotz
+mothership$ git checkout master
+mothership$ git merge satellite/master <5>
+------------
++
+<1> mothership machine has a frotz repository under your home
+directory; clone from it to start a repository on the satellite
+machine.
+<2> clone sets these configuration variables by default.
+It arranges `git pull` to fetch and store the branches of mothership
+machine to local `remotes/origin/*` remote-tracking branches.
+<3> arrange `git push` to push all local branches to
+their corresponding branch of the mothership machine.
+<4> push will stash all our work away on `remotes/satellite/*`
+remote-tracking branches on the mothership machine.  You could use this
+as a back-up method. Likewise, you can pretend that mothership
+"fetched" from you (useful when access is one sided).
+<5> on mothership machine, merge the work done on the satellite
+machine into the master branch.
+
+Branch off of a specific tag.::
++
+------------
+$ git checkout -b private2.6.14 v2.6.14 <1>
+$ edit/compile/test; git commit -a
+$ git checkout master
+$ git cherry-pick v2.6.14..private2.6.14 <2>
+------------
++
+<1> create a private branch based on a well known (but somewhat behind)
+tag.
+<2> forward port all changes in `private2.6.14` branch to `master` branch
+without a formal "merging". Or longhand +
+`git format-patch -k -m --stdout v2.6.14..private2.6.14 |
+  git am -3 -k`
+
+An alternate participant submission mechanism is using the
+`git request-pull` or pull-request mechanisms (e.g as used on
+GitHub (www.github.com) to notify your upstream of your
+contribution.
+
+Integrator[[INTEGRATOR]]
+------------------------
+
+A fairly central person acting as the integrator in a group
+project receives changes made by others, reviews and integrates
+them and publishes the result for others to use, using these
+commands in addition to the ones needed by participants.
+
+This section can also be used by those who respond to `git
+request-pull` or pull-request on GitHub (www.github.com) to
+integrate the work of others into their history. An sub-area
+lieutenant for a repository will act both as a participant and
+as an integrator.
+
+
+  * linkgit:git-am[1] to apply patches e-mailed in from your
+    contributors.
+
+  * linkgit:git-pull[1] to merge from your trusted lieutenants.
+
+  * linkgit:git-format-patch[1] to prepare and send suggested
+    alternative to contributors.
+
+  * linkgit:git-revert[1] to undo botched commits.
+
+  * linkgit:git-push[1] to publish the bleeding edge.

+
+Repository Administration[[ADMINISTRATION]]
+-------------------------------------------
+
+A repository administrator uses the following tools to set up
+and maintain access to the repository by developers.
+
+  * linkgit:git-daemon[1] to allow anonymous download from
+    repository.
+
+  * linkgit:git-shell[1] can be used as a 'restricted login shell'
+    for shared central repository users.
+
+  * linkgit:git-http-backend[1] provides a server side implementation
+    of Git-over-HTTP ("Smart http") allowing both fetch and push services.
+
+  * linkgit:gitweb[1] provides a web front-end to Git repositories,
+    which can be set-up using the linkgit:git-instaweb[1] script.
+
+link:howto/update-hook-example.html[update hook howto] has a good
+example of managing a shared central repository.
+
+In addition there are a number of other widely deployed hosting, browsing
+and reviewing solutions such as:
+
+  * gitolite, gerrit code review, cgit and others.
+

+SHA-1>` will be 40 `0`.  If the local commit was specified by something other
+than a name which could be expanded (such as `HEAD~`, or a SHA-1) it will be
+supplied as it was originally given.

+NAME
+----
+gitnamespaces - Git namespaces
+
+SYNOPSIS
+--------
+[verse]
+GIT_NAMESPACE=<namespace> 'git upload-pack'
+GIT_NAMESPACE=<namespace> 'git receive-pack'
+
+
+DESCRIPTION
+-----------
+
+Git supports dividing the refs of a single repository into multiple
+namespaces, each of which has its own branches, tags, and HEAD.  Git can
+expose each namespace as an independent repository to pull from and push
+to, while sharing the object store, and exposing all the refs to
+operations such as linkgit:git-gc[1].
+
+Storing multiple repositories as namespaces of a single repository
+avoids storing duplicate copies of the same objects, such as when
+storing multiple branches of the same source.  The alternates mechanism
+provides similar support for avoiding duplicates, but alternates do not
+prevent duplication between new objects added to the repositories
+without ongoing maintenance, while namespaces do.
+
+To specify a namespace, set the `GIT_NAMESPACE` environment variable to
+the namespace.  For each ref namespace, Git stores the corresponding
+refs in a directory under `refs/namespaces/`.  For example,
+`GIT_NAMESPACE=foo` will store refs under `refs/namespaces/foo/`.  You
+can also specify namespaces via the `--namespace` option to
+linkgit:git[1].
+
+Note that namespaces which include a `/` will expand to a hierarchy of
+namespaces; for example, `GIT_NAMESPACE=foo/bar` will store refs under
+`refs/namespaces/foo/refs/namespaces/bar/`.  This makes paths in
+`GIT_NAMESPACE` behave hierarchically, so that cloning with
+`GIT_NAMESPACE=foo/bar` produces the same result as cloning with
+`GIT_NAMESPACE=foo` and cloning from that repo with `GIT_NAMESPACE=bar`.  It
+also avoids ambiguity with strange namespace paths such as `foo/refs/heads/`,
+which could otherwise generate directory/file conflicts within the `refs`
+directory.
+
+linkgit:git-upload-pack[1] and linkgit:git-receive-pack[1] rewrite the
+names of refs as specified by `GIT_NAMESPACE`.  git-upload-pack and
+git-receive-pack will ignore all references outside the specified
+namespace.
+
+The smart HTTP server, linkgit:git-http-backend[1], will pass
+GIT_NAMESPACE through to the backend programs; see
+linkgit:git-http-backend[1] for sample configuration to expose
+repository namespaces as repositories.
+
+For a simple local test, you can use linkgit:git-remote-ext[1]:
+
+----------
+git clone ext::'git --namespace=foo %s /tmp/prefixed.git'
+----------
+
+SECURITY
+--------
+
+Anyone with access to any namespace within a repository can potentially
+access objects from any other namespace stored in the same repository.
+You can't directly say "give me object ABCD" if you don't have a ref to
+it, but you can do some other sneaky things like:
+
+. Claiming to push ABCD, at which point the server will optimize out the
+  need for you to actually send it. Now you have a ref to ABCD and can
+  fetch it (claiming not to have it, of course).
+
+. Requesting other refs, claiming that you have ABCD, at which point the
+  server may generate deltas against ABCD.
+
+None of this causes a problem if you only host public repositories, or
+if everyone who may read one namespace may also read everything in every
+other namespace (for instance, if everyone in an organization has read
+permission to every repository).

+NAME
+----
+gitremote-helpers - Helper programs to interact with remote repositories
+
+SYNOPSIS
+--------
+[verse]
+'git remote-<transport>' <repository> [<URL>]
+
+DESCRIPTION
+-----------
+
+Remote helper programs are normally not used directly by end users,
+but they are invoked by Git when it needs to interact with remote
+repositories Git does not support natively.  A given helper will
+implement a subset of the capabilities documented here. When Git
+needs to interact with a repository using a remote helper, it spawns
+the helper as an independent process, sends commands to the helper's
+standard input, and expects results from the helper's standard
+output. Because a remote helper runs as an independent process from
+Git, there is no need to re-link Git to add a new helper, nor any
+need to link the helper with the implementation of Git.
+
+Every helper must support the "capabilities" command, which Git
+uses to determine what other commands the helper will accept.  Those
+other commands can be used to discover and update remote refs,
+transport objects between the object database and the remote repository,
+and update the local object store.
+
+Git comes with a "curl" family of remote helpers, that handle various
+transport protocols, such as 'git-remote-http', 'git-remote-https',
+'git-remote-ftp' and 'git-remote-ftps'. They implement the capabilities
+'fetch', 'option', and 'push'.
+
+INVOCATION
+----------
+
+Remote helper programs are invoked with one or (optionally) two
+arguments. The first argument specifies a remote repository as in Git;
+it is either the name of a configured remote or a URL. The second
+argument specifies a URL; it is usually of the form
+'<transport>://<address>', but any arbitrary string is possible.
+The 'GIT_DIR' environment variable is set up for the remote helper
+and can be used to determine where to store additional data or from
+which directory to invoke auxiliary Git commands.
+
+When Git encounters a URL of the form '<transport>://<address>', where
+'<transport>' is a protocol that it cannot handle natively, it
+automatically invokes 'git remote-<transport>' with the full URL as
+the second argument. If such a URL is encountered directly on the
+command line, the first argument is the same as the second, and if it
+is encountered in a configured remote, the first argument is the name
+of that remote.
+
+A URL of the form '<transport>::<address>' explicitly instructs Git to
+invoke 'git remote-<transport>' with '<address>' as the second
+argument. If such a URL is encountered directly on the command line,
+the first argument is '<address>', and if it is encountered in a
+configured remote, the first argument is the name of that remote.
+
+Additionally, when a configured remote has 'remote.<name>.vcs' set to
+'<transport>', Git explicitly invokes 'git remote-<transport>' with
+'<name>' as the first argument. If set, the second argument is
+'remote.<name>.url'; otherwise, the second argument is omitted.
+
+INPUT FORMAT
+------------
+
+Git sends the remote helper a list of commands on standard input, one
+per line.  The first command is always the 'capabilities' command, in
+response to which the remote helper must print a list of the
+capabilities it supports (see below) followed by a blank line.  The
+response to the capabilities command determines what commands Git uses
+in the remainder of the command stream.
+
+The command stream is terminated by a blank line.  In some cases
+(indicated in the documentation of the relevant commands), this blank
+line is followed by a payload in some other protocol (e.g., the pack
+protocol), while in others it indicates the end of input.
+
+Capabilities
+~~~~~~~~~~~~
+
+Each remote helper is expected to support only a subset of commands.
+The operations a helper supports are declared to Git in the response
+to the `capabilities` command (see COMMANDS, below).
+
+In the following, we list all defined capabilities and for
+each we list which commands a helper with that capability
+must provide.
+
+Capabilities for Pushing
+^^^^^^^^^^^^^^^^^^^^^^^^
+'connect'::
+	Can attempt to connect to 'git receive-pack' (for pushing),
+	'git upload-pack', etc for communication using
+	git's native packfile protocol. This
+	requires a bidirectional, full-duplex connection.
++
+Supported commands: 'connect'.
+
+'push'::
+	Can discover remote refs and push local commits and the
+	history leading up to them to new or existing remote refs.
++
+Supported commands: 'list for-push', 'push'.
+
+'export'::
+	Can discover remote refs and push specified objects from a
+	fast-import stream to remote refs.
++
+Supported commands: 'list for-push', 'export'.
+
+If a helper advertises 'connect', Git will use it if possible and
+fall back to another capability if the helper requests so when
+connecting (see the 'connect' command under COMMANDS).
+When choosing between 'push' and 'export', Git prefers 'push'.
+Other frontends may have some other order of preference.
+
+'no-private-update'::
+	When using the 'refspec' capability, git normally updates the
+	private ref on successful push. This update is disabled when
+	the remote-helper declares the capability 'no-private-update'.
+
+
+Capabilities for Fetching
+^^^^^^^^^^^^^^^^^^^^^^^^^
+'connect'::
+	Can try to connect to 'git upload-pack' (for fetching),
+	'git receive-pack', etc for communication using the
+	Git's native packfile protocol. This
+	requires a bidirectional, full-duplex connection.
++
+Supported commands: 'connect'.
+
+'fetch'::
+	Can discover remote refs and transfer objects reachable from
+	them to the local object store.
++
+Supported commands: 'list', 'fetch'.
+
+'import'::
+	Can discover remote refs and output objects reachable from
+	them as a stream in fast-import format.
++
+Supported commands: 'list', 'import'.
+
+'check-connectivity'::
+	Can guarantee that when a clone is requested, the received
+	pack is self contained and is connected.
+
+If a helper advertises 'connect', Git will use it if possible and
+fall back to another capability if the helper requests so when
+connecting (see the 'connect' command under COMMANDS).
+When choosing between 'fetch' and 'import', Git prefers 'fetch'.
+Other frontends may have some other order of preference.
+
+Miscellaneous capabilities
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+'option'::
+	For specifying settings like `verbosity` (how much output to
+	write to stderr) and `depth` (how much history is wanted in the
+	case of a shallow clone) that affect how other commands are
+	carried out.
+
+'refspec' <refspec>::
+	For remote helpers that implement 'import' or 'export', this capability
+	allows the refs to be constrained to a private namespace, instead of
+	writing to refs/heads or refs/remotes directly.
+	It is recommended that all importers providing the 'import'
+	capability use this. It's mandatory for 'export'.
++
+A helper advertising the capability
+`refspec refs/heads/*:refs/svn/origin/branches/*`
+is saying that, when it is asked to `import refs/heads/topic`, the
+stream it outputs will update the `refs/svn/origin/branches/topic`
+ref.
++
+This capability can be advertised multiple times.  The first
+applicable refspec takes precedence.  The left-hand of refspecs
+advertised with this capability must cover all refs reported by
+the list command.  If no 'refspec' capability is advertised,
+there is an implied `refspec *:*`.
++
+When writing remote-helpers for decentralized version control
+systems, it is advised to keep a local copy of the repository to
+interact with, and to let the private namespace refs point to this
+local repository, while the refs/remotes namespace is used to track
+the remote repository.
+
+'bidi-import'::
+	This modifies the 'import' capability.
+	The fast-import commands 'cat-blob' and 'ls' can be used by remote-helpers
+	to retrieve information about blobs and trees that already exist in
+	fast-import's memory. This requires a channel from fast-import to the
+	remote-helper.
+	If it is advertised in addition to "import", Git establishes a pipe from
+	fast-import to the remote-helper's stdin.
+	It follows that Git and fast-import are both connected to the
+	remote-helper's stdin. Because Git can send multiple commands to
+	the remote-helper it is required that helpers that use 'bidi-import'
+	buffer all 'import' commands of a batch before sending data to fast-import.
+	This is to prevent mixing commands and fast-import responses on the
+	helper's stdin.
+
+'export-marks' <file>::
+	This modifies the 'export' capability, instructing Git to dump the
+	internal marks table to <file> when complete. For details,
+	read up on '--export-marks=<file>' in linkgit:git-fast-export[1].
+
+'import-marks' <file>::
+	This modifies the 'export' capability, instructing Git to load the
+	marks specified in <file> before processing any input. For details,
+	read up on '--import-marks=<file>' in linkgit:git-fast-export[1].
+
+'signed-tags'::
+	This modifies the 'export' capability, instructing Git to pass
+	'--signed-tags=verbatim' to linkgit:git-fast-export[1].  In the
+	absence of this capability, Git will use '--signed-tags=warn-strip'.
+
+
+
+COMMANDS
+--------
+
+Commands are given by the caller on the helper's standard input, one per line.
+
+'capabilities'::
+	Lists the capabilities of the helper, one per line, ending
+	with a blank line. Each capability may be preceded with '*',
+	which marks them mandatory for Git versions using the remote
+	helper to understand. Any unknown mandatory capability is a
+	fatal error.
++
+Support for this command is mandatory.
+
+'list'::
+	Lists the refs, one per line, in the format "<value> <name>
+	[<attr> ...]". The value may be a hex sha1 hash, "@<dest>" for
+	a symref, or "?" to indicate that the helper could not get the
+	value of the ref. A space-separated list of attributes follows
+	the name; unrecognized attributes are ignored. The list ends
+	with a blank line.
++
+See REF LIST ATTRIBUTES for a list of currently defined attributes.
++
+Supported if the helper has the "fetch" or "import" capability.
+
+'list for-push'::
+	Similar to 'list', except that it is used if and only if
+	the caller wants to the resulting ref list to prepare
+	push commands.
+	A helper supporting both push and fetch can use this
+	to distinguish for which operation the output of 'list'
+	is going to be used, possibly reducing the amount
+	of work that needs to be performed.
++
+Supported if the helper has the "push" or "export" capability.
+
+'option' <name> <value>::
+	Sets the transport helper option <name> to <value>.  Outputs a
+	single line containing one of 'ok' (option successfully set),
+	'unsupported' (option not recognized) or 'error <msg>'
+	(option <name> is supported but <value> is not valid
+	for it).  Options should be set before other commands,
+	and may influence the behavior of those commands.
++
+See OPTIONS for a list of currently defined options.
++
+Supported if the helper has the "option" capability.
+
+'fetch' <sha1> <name>::
+	Fetches the given object, writing the necessary objects
+	to the database.  Fetch commands are sent in a batch, one
+	per line, terminated with a blank line.
+	Outputs a single blank line when all fetch commands in the
+	same batch are complete. Only objects which were reported
+	in the output of 'list' with a sha1 may be fetched this way.
++
+Optionally may output a 'lock <file>' line indicating a file under
+GIT_DIR/objects/pack which is keeping a pack until refs can be
+suitably updated.
++
+If option 'check-connectivity' is requested, the helper must output
+'connectivity-ok' if the clone is self-contained and connected.
++
+Supported if the helper has the "fetch" capability.
+
+'push' +<src>:<dst>::
+	Pushes the given local <src> commit or branch to the
+	remote branch described by <dst>.  A batch sequence of
+	one or more 'push' commands is terminated with a blank line
+	(if there is only one reference to push, a single 'push' command
+	is followed by a blank line). For example, the following would
+	be two batches of 'push', the first asking the remote-helper
+	to push the local ref 'master' to the remote ref 'master' and
+	the local 'HEAD' to the remote 'branch', and the second
+	asking to push ref 'foo' to ref 'bar' (forced update requested
+	by the '+').
++
+------------
+push refs/heads/master:refs/heads/master
+push HEAD:refs/heads/branch
+\n
+push +refs/heads/foo:refs/heads/bar
+\n
+------------
++
+Zero or more protocol options may be entered after the last 'push'
+command, before the batch's terminating blank line.
++
+When the push is complete, outputs one or more 'ok <dst>' or
+'error <dst> <why>?' lines to indicate success or failure of
+each pushed ref.  The status report output is terminated by
+a blank line.  The option field <why> may be quoted in a C
+style string if it contains an LF.
++
+Supported if the helper has the "push" capability.
+
+'import' <name>::
+	Produces a fast-import stream which imports the current value
+	of the named ref. It may additionally import other refs as
+	needed to construct the history efficiently. The script writes
+	to a helper-specific private namespace. The value of the named
+	ref should be written to a location in this namespace derived
+	by applying the refspecs from the "refspec" capability to the
+	name of the ref.
++
+Especially useful for interoperability with a foreign versioning
+system.
++
+Just like 'push', a batch sequence of one or more 'import' is
+terminated with a blank line. For each batch of 'import', the remote
+helper should produce a fast-import stream terminated by a 'done'
+command.
++
+Note that if the 'bidi-import' capability is used the complete batch
+sequence has to be buffered before starting to send data to fast-import
+to prevent mixing of commands and fast-import responses on the helper's
+stdin.
++
+Supported if the helper has the "import" capability.
+
+'export'::
+	Instructs the remote helper that any subsequent input is
+	part of a fast-import stream (generated by 'git fast-export')
+	containing objects which should be pushed to the remote.
++
+Especially useful for interoperability with a foreign versioning
+system.
++
+The 'export-marks' and 'import-marks' capabilities, if specified,
+affect this command in so far as they are passed on to 'git
+fast-export', which then will load/store a table of marks for
+local objects. This can be used to implement for incremental
+operations.
++
+Supported if the helper has the "export" capability.
+
+'connect' <service>::
+	Connects to given service. Standard input and standard output
+	of helper are connected to specified service (git prefix is
+	included in service name so e.g. fetching uses 'git-upload-pack'
+	as service) on remote side. Valid replies to this command are
+	empty line (connection established), 'fallback' (no smart
+	transport support, fall back to dumb transports) and just
+	exiting with error message printed (can't connect, don't
+	bother trying to fall back). After line feed terminating the
+	positive (empty) response, the output of service starts. After
+	the connection ends, the remote helper exits.
++
+Supported if the helper has the "connect" capability.
+
+If a fatal error occurs, the program writes the error message to
+stderr and exits. The caller should expect that a suitable error
+message has been printed if the child closes the connection without
+completing a valid response for the current command.
+
+Additional commands may be supported, as may be determined from
+capabilities reported by the helper.
+
+REF LIST ATTRIBUTES
+-------------------
+
+The 'list' command produces a list of refs in which each ref
+may be followed by a list of attributes. The following ref list
+attributes are defined.
+
+'unchanged'::
+	This ref is unchanged since the last import or fetch, although
+	the helper cannot necessarily determine what value that produced.
+
+OPTIONS
+-------
+
+The following options are defined and (under suitable circumstances)
+set by Git if the remote helper has the 'option' capability.
+
+'option verbosity' <n>::
+	Changes the verbosity of messages displayed by the helper.
+	A value of 0 for <n> means that processes operate
+	quietly, and the helper produces only error output.
+	1 is the default level of verbosity, and higher values
+	of <n> correspond to the number of -v flags passed on the
+	command line.
+
+'option progress' \{'true'|'false'\}::
+	Enables (or disables) progress messages displayed by the
+	transport helper during a command.
+
+'option depth' <depth>::
+	Deepens the history of a shallow repository.
+
+'option followtags' \{'true'|'false'\}::
+	If enabled the helper should automatically fetch annotated
+	tag objects if the object the tag points at was transferred
+	during the fetch command.  If the tag is not fetched by
+	the helper a second fetch command will usually be sent to
+	ask for the tag specifically.  Some helpers may be able to
+	use this option to avoid a second network connection.
+
+'option dry-run' \{'true'|'false'\}:
+	If true, pretend the operation completed successfully,
+	but don't actually change any repository data.	For most
+	helpers this only applies to the 'push', if supported.
+
+'option servpath <c-style-quoted-path>'::
+	Sets service path (--upload-pack, --receive-pack etc.) for
+	next connect. Remote helper may support this option, but
+	must not rely on this option being set before
+	connect request occurs.
+
+'option check-connectivity' \{'true'|'false'\}::
+	Request the helper to check connectivity of a clone.
+
+'option force' \{'true'|'false'\}::
+	Request the helper to perform a force update.  Defaults to
+	'false'.
+
+'option cloning \{'true'|'false'\}::
+	Notify the helper this is a clone request (i.e. the current
+	repository is guaranteed empty).
+
+'option update-shallow \{'true'|'false'\}::
+	Allow to extend .git/shallow if the new refs require it.

 DESCRIPTION
 -----------
 
-You may find these things in your git repository (`.git`

-`<project>.git` directory for a public 'bare' repository. It is
-also possible to have a working tree where `.git` is a plain
-ascii file containing `gitdir: <path>`, i.e. the path to the
-real git repository).
+A Git repository comes in two different flavours:
+
+ * a `.git` directory at the root of the working tree;
+
+ * a `<project>.git` directory that is a 'bare' repository
+   (i.e. without its own working tree), that is typically used for
+   exchanging histories with others by pushing into it and fetching
+   from it.
+
+*Note*: Also you can have a plain text file `.git` at the root of
+your working tree, containing `gitdir: <path>` to point at the real
+directory that has the repository.  This mechanism is often used for
+a working tree of a submodule checkout, to allow you in the
+containing superproject to `git checkout` a branch that does not
+have the submodule.  The `checkout` has to remove the entire
+submodule working tree, without losing the submodule repository.
+
+These things may exist in a Git repository.

+NAME
+----
+gitweb.conf - Gitweb (Git web interface) configuration file
+
+SYNOPSIS
+--------
+/etc/gitweb.conf, /etc/gitweb-common.conf, $GITWEBDIR/gitweb_config.perl
+
+DESCRIPTION
+-----------
+
+The gitweb CGI script for viewing Git repositories over the web uses a
+perl script fragment as its configuration file.  You can set variables
+using "`our $variable = value`"; text from a "#" character until the
+end of a line is ignored.  See *perlsyn*(1) for details.
+
+An example:
+
+    # gitweb configuration file for http://git.example.org
+    #
+    our $projectroot = "/srv/git"; # FHS recommendation
+    our $site_name = 'Example.org >> Repos';
+
+
+The configuration file is used to override the default settings that
+were built into gitweb at the time the 'gitweb.cgi' script was generated.
+
+While one could just alter the configuration settings in the gitweb
+CGI itself, those changes would be lost upon upgrade.  Configuration
+settings might also be placed into a file in the same directory as the
+CGI script with the default name 'gitweb_config.perl' -- allowing
+one to have multiple gitweb instances with different configurations by
+the use of symlinks.
+
+Note that some configuration can be controlled on per-repository rather than
+gitweb-wide basis: see "Per-repository gitweb configuration" subsection on
+linkgit:gitweb[1] manpage.
+
+
+DISCUSSION
+----------
+Gitweb reads configuration data from the following sources in the
+following order:
+
+ * built-in values (some set during build stage),
+
+ * common system-wide configuration file (defaults to
+   '/etc/gitweb-common.conf'),
+
+ * either per-instance configuration file (defaults to 'gitweb_config.perl'
+   in the same directory as the installed gitweb), or if it does not exists
+   then fallback system-wide configuration file (defaults to '/etc/gitweb.conf').
+
+Values obtained in later configuration files override values obtained earlier
+in the above sequence.
+
+Locations of the common system-wide configuration file, the fallback
+system-wide configuration file and the per-instance configuration file
+are defined at compile time using build-time Makefile configuration
+variables, respectively `GITWEB_CONFIG_COMMON`, `GITWEB_CONFIG_SYSTEM`
+and `GITWEB_CONFIG`.
+
+You can also override locations of gitweb configuration files during
+runtime by setting the following environment variables:
+`GITWEB_CONFIG_COMMON`, `GITWEB_CONFIG_SYSTEM` and `GITWEB_CONFIG`
+to a non-empty value.
+
+
+The syntax of the configuration files is that of Perl, since these files are
+handled by sourcing them as fragments of Perl code (the language that
+gitweb itself is written in). Variables are typically set using the
+`our` qualifier (as in "`our $variable = <value>;`") to avoid syntax
+errors if a new version of gitweb no longer uses a variable and therefore
+stops declaring it.
+
+You can include other configuration file using read_config_file()
+subroutine.  For example, one might want to put gitweb configuration
+related to access control for viewing repositories via Gitolite (one
+of Git repository management tools) in a separate file, e.g. in
+'/etc/gitweb-gitolite.conf'.  To include it, put
+
+--------------------------------------------------
+read_config_file("/etc/gitweb-gitolite.conf");
+--------------------------------------------------
+
+somewhere in gitweb configuration file used, e.g. in per-installation
+gitweb configuration file.  Note that read_config_file() checks itself
+that the file it reads exists, and does nothing if it is not found.
+It also handles errors in included file.
+
+
+The default configuration with no configuration file at all may work
+perfectly well for some installations.  Still, a configuration file is
+useful for customizing or tweaking the behavior of gitweb in many ways, and
+some optional features will not be present unless explicitly enabled using
+the configurable `%features` variable (see also "Configuring gitweb
+features" section below).
+
+
+CONFIGURATION VARIABLES
+-----------------------
+Some configuration variables have their default values (embedded in the CGI
+script) set during building gitweb -- if that is the case, this fact is put
+in their description.  See gitweb's 'INSTALL' file for instructions on building
+and installing gitweb.
+
+
+Location of repositories
+~~~~~~~~~~~~~~~~~~~~~~~~
+The configuration variables described below control how gitweb finds
+Git repositories, and how repositories are displayed and accessed.
+
+See also "Repositories" and later subsections in linkgit:gitweb[1] manpage.
+
+$projectroot::
+	Absolute filesystem path which will be prepended to project path;
+	the path to repository is `$projectroot/$project`.  Set to
+	`$GITWEB_PROJECTROOT` during installation.  This variable has to be
+	set correctly for gitweb to find repositories.
++
+For example, if `$projectroot` is set to "/srv/git" by putting the following
+in gitweb config file:
++
+----------------------------------------------------------------------------
+our $projectroot = "/srv/git";
+----------------------------------------------------------------------------
++
+then
++
+------------------------------------------------
+http://git.example.com/gitweb.cgi?p=foo/bar.git
+------------------------------------------------
++
+and its path_info based equivalent
++
+------------------------------------------------
+http://git.example.com/gitweb.cgi/foo/bar.git
+------------------------------------------------
++
+will map to the path '/srv/git/foo/bar.git' on the filesystem.
+
+$projects_list::
+	Name of a plain text file listing projects, or a name of directory
+	to be scanned for projects.
++
+Project list files should list one project per line, with each line
+having the following format
++
+-----------------------------------------------------------------------------
+<URI-encoded filesystem path to repository> SP <URI-encoded repository owner>
+-----------------------------------------------------------------------------
++
+The default value of this variable is determined by the `GITWEB_LIST`
+makefile variable at installation time.  If this variable is empty, gitweb
+will fall back to scanning the `$projectroot` directory for repositories.
+
+$project_maxdepth::
+	If `$projects_list` variable is unset, gitweb will recursively
+	scan filesystem for Git repositories.  The `$project_maxdepth`
+	is used to limit traversing depth, relative to `$projectroot`
+	(starting point); it means that directories which are further
+	from `$projectroot` than `$project_maxdepth` will be skipped.
++
+It is purely performance optimization, originally intended for MacOS X,
+where recursive directory traversal is slow.  Gitweb follows symbolic
+links, but it detects cycles, ignoring any duplicate files and directories.
++
+The default value of this variable is determined by the build-time
+configuration variable `GITWEB_PROJECT_MAXDEPTH`, which defaults to
+2007.
+
+$export_ok::
+	Show repository only if this file exists (in repository).  Only
+	effective if this variable evaluates to true.  Can be set when
+	building gitweb by setting `GITWEB_EXPORT_OK`.  This path is
+	relative to `GIT_DIR`.  git-daemon[1] uses 'git-daemon-export-ok',
+	unless started with `--export-all`.  By default this variable is
+	not set, which means that this feature is turned off.
+
+$export_auth_hook::
+	Function used to determine which repositories should be shown.
+	This subroutine should take one parameter, the full path to
+	a project, and if it returns true, that project will be included
+	in the projects list and can be accessed through gitweb as long
+	as it fulfills the other requirements described by $export_ok,
+	$projects_list, and $projects_maxdepth.  Example:
++
+----------------------------------------------------------------------------
+our $export_auth_hook = sub { return -e "$_[0]/git-daemon-export-ok"; };
+----------------------------------------------------------------------------
++
+though the above might be done by using `$export_ok` instead
++
+----------------------------------------------------------------------------
+our $export_ok = "git-daemon-export-ok";
+----------------------------------------------------------------------------
++
+If not set (default), it means that this feature is disabled.
++
+See also more involved example in "Controlling access to Git repositories"
+subsection on linkgit:gitweb[1] manpage.
+
+$strict_export::
+	Only allow viewing of repositories also shown on the overview page.
+	This for example makes `$gitweb_export_ok` file decide if repository is
+	available and not only if it is shown.  If `$gitweb_list` points to
+	file with list of project, only those repositories listed would be
+	available for gitweb.  Can be set during building gitweb via
+	`GITWEB_STRICT_EXPORT`.  By default this variable is not set, which
+	means that you can directly access those repositories that are hidden
+	from projects list page (e.g. the are not listed in the $projects_list
+	file).
+
+
+Finding files
+~~~~~~~~~~~~~
+The following configuration variables tell gitweb where to find files.
+The values of these variables are paths on the filesystem.
+
+$GIT::
+	Core git executable to use.  By default set to `$GIT_BINDIR/git`, which
+	in turn is by default set to `$(bindir)/git`.  If you use Git installed
+	from a binary package, you should usually set this to "/usr/bin/git".
+	This can just be "git" if your web server has a sensible PATH; from
+	security point of view it is better to use absolute path to git binary.
+	If you have multiple Git versions installed it can be used to choose
+	which one to use.  Must be (correctly) set for gitweb to be able to
+	work.
+
+$mimetypes_file::
+	File to use for (filename extension based) guessing of MIME types before
+	trying '/etc/mime.types'.  *NOTE* that this path, if relative, is taken
+	as relative to the current Git repository, not to CGI script.  If unset,
+	only '/etc/mime.types' is used (if present on filesystem).  If no mimetypes
+	file is found, mimetype guessing based on extension of file is disabled.
+	Unset by default.
+
+$highlight_bin::
+	Path to the highlight executable to use (it must be the one from
+	http://www.andre-simon.de[] due to assumptions about parameters and output).
+	By default set to 'highlight'; set it to full path to highlight
+	executable if it is not installed on your web server's PATH.
+	Note that 'highlight' feature must be set for gitweb to actually
+	use syntax highlighting.
++
+*NOTE*: if you want to add support for new file type (supported by
+"highlight" but not used by gitweb), you need to modify `%highlight_ext`
+or `%highlight_basename`, depending on whether you detect type of file
+based on extension (for example "sh") or on its basename (for example
+"Makefile").  The keys of these hashes are extension and basename,
+respectively, and value for given key is name of syntax to be passed via
+`--syntax <syntax>` to highlighter.
++
+For example if repositories you are hosting use "phtml" extension for
+PHP files, and you want to have correct syntax-highlighting for those
+files, you can add the following to gitweb configuration:
++
+---------------------------------------------------------
+our %highlight_ext;
+$highlight_ext{'phtml'} = 'php';
+---------------------------------------------------------
+
+
+Links and their targets
+~~~~~~~~~~~~~~~~~~~~~~~
+The configuration variables described below configure some of gitweb links:
+their target and their look (text or image), and where to find page
+prerequisites (stylesheet, favicon, images, scripts).  Usually they are left
+at their default values, with the possible exception of `@stylesheets`
+variable.
+
+@stylesheets::
+	List of URIs of stylesheets (relative to the base URI of a page). You
+	might specify more than one stylesheet, for example to use "gitweb.css"
+	as base with site specific modifications in a separate stylesheet
+	to make it easier to upgrade gitweb.  For example, you can add
+	a `site` stylesheet by putting
++
+----------------------------------------------------------------------------
+push @stylesheets, "gitweb-site.css";
+----------------------------------------------------------------------------
++
+in the gitweb config file.  Those values that are relative paths are
+relative to base URI of gitweb.
++
+This list should contain the URI of gitweb's standard stylesheet.  The default
+URI of gitweb stylesheet can be set at build time using the `GITWEB_CSS`
+makefile variable.  Its default value is 'static/gitweb.css'
+(or 'static/gitweb.min.css' if the `CSSMIN` variable is defined,
+i.e. if CSS minifier is used during build).
++
+*Note*: there is also a legacy `$stylesheet` configuration variable, which was
+used by older gitweb.  If `$stylesheet` variable is defined, only CSS stylesheet
+given by this variable is used by gitweb.
+
+$logo::
+	Points to the location where you put 'git-logo.png' on your web
+	server, or to be more the generic URI of logo, 72x27 size).  This image
+	is displayed in the top right corner of each gitweb page and used as
+	a logo for the Atom feed.  Relative to the base URI of gitweb (as a path).
+	Can be adjusted when building gitweb using `GITWEB_LOGO` variable
+	By default set to 'static/git-logo.png'.
+
+$favicon::
+	Points to the location where you put 'git-favicon.png' on your web
+	server, or to be more the generic URI of favicon, which will be served
+	as "image/png" type.  Web browsers that support favicons (website icons)
+	may display them in the browser's URL bar and next to the site name in
+	bookmarks.  Relative to the base URI of gitweb.  Can be adjusted at
+	build time using `GITWEB_FAVICON` variable.
+	By default set to 'static/git-favicon.png'.
+
+$javascript::
+	Points to the location where you put 'gitweb.js' on your web server,
+	or to be more generic the URI of JavaScript code used by gitweb.
+	Relative to the base URI of gitweb.  Can be set at build time using
+	the `GITWEB_JS` build-time configuration variable.
++
+The default value is either 'static/gitweb.js', or 'static/gitweb.min.js' if
+the `JSMIN` build variable was defined, i.e. if JavaScript minifier was used
+at build time.  *Note* that this single file is generated from multiple
+individual JavaScript "modules".
+
+$home_link::
+	Target of the home link on the top of all pages (the first part of view
+	"breadcrumbs").  By default it is set to the absolute URI of a current page
+	(to the value of `$my_uri` variable, or to "/" if `$my_uri` is undefined
+	or is an empty string).
+
+$home_link_str::
+	Label for the "home link" at the top of all pages, leading to `$home_link`
+	(usually the main gitweb page, which contains the projects list).  It is
+	used as the first component of gitweb's "breadcrumb trail":
+	`<home link> / <project> / <action>`.  Can be set at build time using
+	the `GITWEB_HOME_LINK_STR` variable.  By default it is set to "projects",
+	as this link leads to the list of projects.  Another popular choice is to
+	set it to the name of site.  Note that it is treated as raw HTML so it
+	should not be set from untrusted sources.
+
+@extra_breadcrumbs::
+	Additional links to be added to the start of the breadcrumb trail before
+	the home link, to pages that are logically "above" the gitweb projects
+	list, such as the organization and department which host the gitweb
+	server. Each element of the list is a reference to an array, in which
+	element 0 is the link text (equivalent to `$home_link_str`) and element
+	1 is the target URL (equivalent to `$home_link`).
++
+For example, the following setting produces a breadcrumb trail like
+"home / dev / projects / ..." where "projects" is the home link.
+----------------------------------------------------------------------------
+    our @extra_breadcrumbs = (
+      [ 'home' => 'https://www.example.org/' ],
+      [ 'dev'  => 'https://dev.example.org/' ],
+    );
+----------------------------------------------------------------------------
+
+$logo_url::
+$logo_label::
+	URI and label (title) for the Git logo link (or your site logo,
+	if you chose to use different logo image). By default, these both
+	refer to Git homepage, http://git-scm.com[]; in the past, they pointed
+	to Git documentation at http://www.kernel.org[].
+
+
+Changing gitweb's look
+~~~~~~~~~~~~~~~~~~~~~~
+You can adjust how pages generated by gitweb look using the variables described
+below.  You can change the site name, add common headers and footers for all
+pages, and add a description of this gitweb installation on its main page
+(which is the projects list page), etc.
+
+$site_name::
+	Name of your site or organization, to appear in page titles.  Set it
+	to something descriptive for clearer bookmarks etc.  If this variable
+	is not set or is, then gitweb uses the value of the `SERVER_NAME`
+	CGI environment variable, setting site name to "$SERVER_NAME Git",
+	or "Untitled Git" if this variable is not set (e.g. if running gitweb
+	as standalone script).
++
+Can be set using the `GITWEB_SITENAME` at build time.  Unset by default.
+
+$site_html_head_string::
+	HTML snippet to be included in the <head> section of each page.
+	Can be set using `GITWEB_SITE_HTML_HEAD_STRING` at build time.
+	No default value.
+
+$site_header::
+	Name of a file with HTML to be included at the top of each page.
+	Relative to the directory containing the 'gitweb.cgi' script.
+	Can be set using `GITWEB_SITE_HEADER` at build time.  No default
+	value.
+
+$site_footer::
+	Name of a file with HTML to be included at the bottom of each page.
+	Relative to the directory containing the 'gitweb.cgi' script.
+	Can be set using `GITWEB_SITE_FOOTER` at build time.  No default
+	value.
+
+$home_text::
+	Name of a HTML file which, if it exists, is included on the
+	gitweb projects overview page ("projects_list" view).  Relative to
+	the directory containing the gitweb.cgi script.  Default value
+	can be adjusted during build time using `GITWEB_HOMETEXT` variable.
+	By default set to 'indextext.html'.
+
+$projects_list_description_width::
+	The width (in characters) of the "Description" column of the projects list.
+	Longer descriptions will be truncated (trying to cut at word boundary);
+	the full description is available in the 'title' attribute (usually shown on
+	mouseover).  The default is 25, which might be too small if you
+	use long project descriptions.
+
+$default_projects_order::
+	Default value of ordering of projects on projects list page, which
+	means the ordering used if you don't explicitly sort projects list
+	(if there is no "o" CGI query parameter in the URL).  Valid values
+	are "none" (unsorted), "project" (projects are by project name,
+	i.e. path to repository relative to `$projectroot`), "descr"
+	(project description), "owner", and "age" (by date of most current
+	commit).
++
+Default value is "project".  Unknown value means unsorted.
+
+
+Changing gitweb's behavior
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+These configuration variables control _internal_ gitweb behavior.
+
+$default_blob_plain_mimetype::
+	Default mimetype for the blob_plain (raw) view, if mimetype checking
+	doesn't result in some other type; by default "text/plain".
+	Gitweb guesses mimetype of a file to display based on extension
+	of its filename, using `$mimetypes_file` (if set and file exists)
+	and '/etc/mime.types' files (see *mime.types*(5) manpage; only
+	filename extension rules are supported by gitweb).
+
+$default_text_plain_charset::
+	Default charset for text files. If this is not set, the web server
+	configuration will be used.  Unset by default.
+
+$fallback_encoding::
+	Gitweb assumes this charset when a line contains non-UTF-8 characters.
+	The fallback decoding is used without error checking, so it can be even
+	"utf-8". The value must be a valid encoding; see the *Encoding::Supported*(3pm)
+	man page for a list. The default is "latin1", aka. "iso-8859-1".
+
+@diff_opts::
+	Rename detection options for git-diff and git-diff-tree. The default is
+	(\'-M'); set it to (\'-C') or (\'-C', \'-C') to also detect copies,
+	or set it to () i.e. empty list if you don't want to have renames
+	detection.
++
+*Note* that rename and especially copy detection can be quite
+CPU-intensive.  Note also that non Git tools can have problems with
+patches generated with options mentioned above, especially when they
+involve file copies (\'-C') or criss-cross renames (\'-B').
+
+
+Some optional features and policies
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Most of features are configured via `%feature` hash; however some of extra
+gitweb features can be turned on and configured using variables described
+below.  This list beside configuration variables that control how gitweb
+looks does contain variables configuring administrative side of gitweb
+(e.g. cross-site scripting prevention; admittedly this as side effect
+affects how "summary" pages look like, or load limiting).
+
+@git_base_url_list::
+	List of Git base URLs.  These URLs are used to generate URLs
+	describing from where to fetch a project, which are shown on
+	project summary page.  The full fetch URL is "`$git_base_url/$project`",
+	for each element of this list. You can set up multiple base URLs
+	(for example one for `git://` protocol, and one for `http://`
+	protocol).
++
+Note that per repository configuration can be set in '$GIT_DIR/cloneurl'
+file, or as values of multi-value `gitweb.url` configuration variable in
+project config.  Per-repository configuration takes precedence over value
+composed from `@git_base_url_list` elements and project name.
++
+You can setup one single value (single entry/item in this list) at build
+time by setting the `GITWEB_BASE_URL` built-time configuration variable.
+By default it is set to (), i.e. an empty list.  This means that gitweb
+would not try to create project URL (to fetch) from project name.
+
+$projects_list_group_categories::
+	Whether to enables the grouping of projects by category on the project
+	list page. The category of a project is determined by the
+	`$GIT_DIR/category` file or the `gitweb.category` variable in each
+	repository's configuration.  Disabled by default (set to 0).
+
+$project_list_default_category::
+	Default category for projects for which none is specified.  If this is
+	set to the empty string, such projects will remain uncategorized and
+	listed at the top, above categorized projects.  Used only if project
+	categories are enabled, which means if `$projects_list_group_categories`
+	is true.  By default set to "" (empty string).
+
+$prevent_xss::
+	If true, some gitweb features are disabled to prevent content in
+	repositories from launching cross-site scripting (XSS) attacks.  Set this
+	to true if you don't trust the content of your repositories.
+	False by default (set to 0).
+
+$maxload::
+	Used to set the maximum load that we will still respond to gitweb queries.
+	If the server load exceeds this value then gitweb will return
+	"503 Service Unavailable" error.  The server load is taken to be 0
+	if gitweb cannot determine its value.  Currently it works only on Linux,
+	where it uses '/proc/loadavg'; the load there is the number of active
+	tasks on the system -- processes that are actually running -- averaged
+	over the last minute.
++
+Set `$maxload` to undefined value (`undef`) to turn this feature off.
+The default value is 300.
+
+$omit_age_column::
+	If true, omit the column with date of the most current commit on the
+	projects list page. It can save a bit of I/O and a fork per repository.
+
+$omit_owner::
+	If true prevents displaying information about repository owner.
+
+$per_request_config::
+	If this is set to code reference, it will be run once for each request.
+	You can	set parts of configuration that change per session this way.
+	For example, one might use the following code in a gitweb configuration
+	file
++
+--------------------------------------------------------------------------------
+our $per_request_config = sub {
+	$ENV{GL_USER} = $cgi->remote_user || "gitweb";
+};
+--------------------------------------------------------------------------------
++
+If `$per_request_config` is not a code reference, it is interpreted as boolean
+value.  If it is true gitweb will process config files once per request,
+and if it is false gitweb will process config files only once, each time it
+is executed.  True by default (set to 1).
++
+*NOTE*: `$my_url`, `$my_uri`, and `$base_url` are overwritten with their default
+values before every request, so if you want to change them, be sure to set
+this variable to true or a code reference effecting the desired changes.
++
+This variable matters only when using persistent web environments that
+serve multiple requests using single gitweb instance, like mod_perl,
+FastCGI or Plackup.
+
+
+Other variables
+~~~~~~~~~~~~~~~
+Usually you should not need to change (adjust) any of configuration
+variables described below; they should be automatically set by gitweb to
+correct value.
+
+
+$version::
+	Gitweb version, set automatically when creating gitweb.cgi from
+	gitweb.perl. You might want to modify it if you are running modified
+	gitweb, for example
++
+---------------------------------------------------
+our $version .= " with caching";
+---------------------------------------------------
++
+if you run modified version of gitweb with caching support.  This variable
+is purely informational, used e.g. in the "generator" meta header in HTML
+header.
+
+$my_url::
+$my_uri::
+	Full URL and absolute URL of the gitweb script;
+	in earlier versions of gitweb you might have need to set those
+	variables, but now there should be no need to do it.  See
+	`$per_request_config` if you need to set them still.
+
+$base_url::
+	Base URL for relative URLs in pages generated by gitweb,
+	(e.g. `$logo`, `$favicon`, `@stylesheets` if they are relative URLs),
+	needed and used '<base href="$base_url">' only for URLs with nonempty
+	PATH_INFO.  Usually gitweb sets its value correctly,
+	and there is no need to set this variable, e.g. to $my_uri or "/".
+	See `$per_request_config` if you need to override it anyway.
+
+
+CONFIGURING GITWEB FEATURES
+---------------------------
+Many gitweb features can be enabled (or disabled) and configured using the
+`%feature` hash.  Names of gitweb features are keys of this hash.
+
+Each `%feature` hash element is a hash reference and has the following
+structure:
+----------------------------------------------------------------------
+"<feature_name>" => {
+	"sub" => <feature-sub (subroutine)>,
+	"override" => <allow-override (boolean)>,
+	"default" => [ <options>... ]
+},
+----------------------------------------------------------------------
+Some features cannot be overridden per project.  For those
+features the structure of appropriate `%feature` hash element has a simpler
+form:
+----------------------------------------------------------------------
+"<feature_name>" => {
+	"override" => 0,
+	"default" => [ <options>... ]
+},
+----------------------------------------------------------------------
+As one can see it lacks the \'sub' element.
+
+The meaning of each part of feature configuration is described
+below:
+
+default::
+	List (array reference) of feature parameters (if there are any),
+	used also to toggle (enable or disable) given feature.
++
+Note that it is currently *always* an array reference, even if
+feature doesn't accept any configuration parameters, and \'default'
+is used only to turn it on or off.  In such case you turn feature on
+by setting this element to `[1]`, and torn it off by setting it to
+`[0]`.  See also the passage about the "blame" feature in the "Examples"
+section.
++
+To disable features that accept parameters (are configurable), you
+need to set this element to empty list i.e. `[]`.
+
+override::
+	If this field has a true value then the given feature is
+	overridable, which means that it can be configured
+	(or enabled/disabled) on a per-repository basis.
++
+Usually given "<feature>" is configurable via the `gitweb.<feature>`
+config variable in the per-repository Git configuration file.
++
+*Note* that no feature is overridable by default.
+
+sub::
+	Internal detail of implementation.  What is important is that
+	if this field is not present then per-repository override for
+	given feature is not supported.
++
+You wouldn't need to ever change it in gitweb config file.
+
+
+Features in `%feature`
+~~~~~~~~~~~~~~~~~~~~~~
+The gitweb features that are configurable via `%feature` hash are listed
+below.  This should be a complete list, but ultimately the authoritative
+and complete list is in gitweb.cgi source code, with features described
+in the comments.
+
+blame::
+	Enable the "blame" and "blame_incremental" blob views, showing for
+	each line the last commit that modified it; see linkgit:git-blame[1].
+	This can be very CPU-intensive and is therefore disabled by default.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.blame` configuration variable (boolean).
+
+snapshot::
+	Enable and configure the "snapshot" action, which allows user to
+	download a compressed archive of any tree or commit, as produced
+	by linkgit:git-archive[1] and possibly additionally compressed.
+	This can potentially generate high traffic if you have large project.
++
+The value of \'default' is a list of names of snapshot formats,
+defined in `%known_snapshot_formats` hash, that you wish to offer.
+Supported formats include "tgz", "tbz2", "txz" (gzip/bzip2/xz
+compressed tar archive) and "zip"; please consult gitweb sources for
+a definitive list.  By default only "tgz" is offered.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.blame` configuration variable, which contains
+a comma separated list of formats or "none" to disable snapshots.
+Unknown values are ignored.
+
+grep::
+	Enable grep search, which lists the files in currently selected
+	tree (directory) containing the given string; see linkgit:git-grep[1].
+	This can be potentially CPU-intensive, of course.  Enabled by default.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.grep` configuration variable (boolean).
+
+pickaxe::
+	Enable the so called pickaxe search, which will list the commits
+	that introduced or removed a given string in a file.  This can be
+	practical and quite faster alternative to "blame" action, but it is
+	still potentially CPU-intensive.  Enabled by default.
++
+The pickaxe search is described in linkgit:git-log[1] (the
+description of `-S<string>` option, which refers to pickaxe entry in
+linkgit:gitdiffcore[7] for more details).
++
+This feature can be configured on a per-repository basis by setting
+repository's `gitweb.pickaxe` configuration variable (boolean).
+
+show-sizes::
+	Enable showing size of blobs (ordinary files) in a "tree" view, in a
+	separate column, similar to what `ls -l` does; see description of
+	`-l` option in linkgit:git-ls-tree[1] manpage.  This costs a bit of
+	I/O.  Enabled by default.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.showsizes` configuration variable (boolean).
+
+patches::
+	Enable and configure "patches" view, which displays list of commits in email
+	(plain text) output format; see also linkgit:git-format-patch[1].
+	The value is the maximum number of patches in a patchset generated
+	in "patches" view.  Set the 'default' field to a list containing single
+	item of or to an empty list to disable patch view, or to a list
+	containing a single negative number to remove any limit.
+	Default value is 16.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.patches` configuration variable (integer).
+
+avatar::
+	Avatar support.  When this feature is enabled, views such as
+	"shortlog" or "commit" will display an avatar associated with
+	the email of each committer and author.
++
+Currently available providers are *"gravatar"* and *"picon"*.
+Only one provider at a time can be selected ('default' is one element list).
+If an unknown provider is specified, the feature is disabled.
+*Note* that some providers might require extra Perl packages to be
+installed; see 'gitweb/INSTALL' for more details.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.avatar` configuration variable.
++
+See also `%avatar_size` with pixel sizes for icons and avatars
+("default" is used for one-line like "log" and "shortlog", "double"
+is used for two-line like "commit", "commitdiff" or "tag").  If the
+default font sizes or lineheights are changed (e.g. via adding extra
+CSS stylesheet in `@stylesheets`), it may be appropriate to change
+these values.
+
+highlight::
+	Server-side syntax highlight support in "blob" view.  It requires
+	`$highlight_bin` program to be available (see the description of
+	this variable in the "Configuration variables" section above),
+	and therefore is disabled by default.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.highlight` configuration variable (boolean).
+
+remote_heads::
+	Enable displaying remote heads (remote-tracking branches) in the "heads"
+	list.  In most cases the list of remote-tracking branches is an
+	unnecessary internal private detail, and this feature is therefore
+	disabled by default.  linkgit:git-instaweb[1], which is usually used
+	to browse local repositories, enables and uses this feature.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.remote_heads` configuration variable (boolean).
+
+
+The remaining features cannot be overridden on a per project basis.
+
+search::
+	Enable text search, which will list the commits which match author,
+	committer or commit text to a given string; see the description of
+	`--author`, `--committer` and `--grep` options in linkgit:git-log[1]
+	manpage.  Enabled by default.
++
+Project specific override is not supported.
+
+forks::
+	If this feature is enabled, gitweb considers projects in
+	subdirectories of project root (basename) to be forks of existing
+	projects.  For each project +$projname.git+, projects in the
+	+$projname/+ directory and its subdirectories will not be
+	shown in the main projects list.  Instead, a \'\+' mark is shown
+	next to +$projname+, which links to a "forks" view that lists all
+	the forks (all projects in +$projname/+ subdirectory).  Additionally
+	a "forks" view for a project is linked from project summary page.
++
+If the project list is taken from a file (+$projects_list+ points to a
+file), forks are only recognized if they are listed after the main project
+in that file.
++
+Project specific override is not supported.
+
+actions::
+	Insert custom links to the action bar of all project pages.  This
+	allows you to link to third-party scripts integrating into gitweb.
++
+The "default" value consists of a list of triplets in the form
+`("<label>", "<link>", "<position>")` where "position" is the label
+after which to insert the link, "link" is a format string where `%n`
+expands to the project name, `%f` to the project path within the
+filesystem (i.e. "$projectroot/$project"), `%h` to the current hash
+(\'h' gitweb parameter) and `%b` to the current hash base
+(\'hb' gitweb parameter); `%%` expands to \'%'.
++
+For example, at the time this page was written, the http://repo.or.cz[]
+Git hosting site set it to the following to enable graphical log
+(using the third party tool *git-browser*):
++
+----------------------------------------------------------------------
+$feature{'actions'}{'default'} =
+	[ ('graphiclog', '/git-browser/by-commit.html?r=%n', 'summary')];
+----------------------------------------------------------------------
++
+This adds a link titled "graphiclog" after the "summary" link, leading to
+`git-browser` script, passing `r=<project>` as a query parameter.
++
+Project specific override is not supported.
+
+timed::
+	Enable displaying how much time and how many Git commands it took to
+	generate and display each page in the page footer (at the bottom of
+	page).  For example the footer might contain: "This page took 6.53325
+	seconds and 13 Git commands to generate."  Disabled by default.
++
+Project specific override is not supported.
+
+javascript-timezone::
+	Enable and configure the ability to change a common time zone for dates
+	in gitweb output via JavaScript.  Dates in gitweb output include
+	authordate and committerdate in "commit", "commitdiff" and "log"
+	views, and taggerdate in "tag" view.  Enabled by default.
++
+The value is a list of three values: a default time zone (for if the client
+hasn't selected some other time zone and saved it in a cookie), a name of cookie
+where to store selected time zone, and a CSS class used to mark up
+dates for manipulation.  If you want to turn this feature off, set "default"
+to empty list: `[]`.
++
+Typical gitweb config files will only change starting (default) time zone,
+and leave other elements at their default values:
++
+---------------------------------------------------------------------------
+$feature{'javascript-timezone'}{'default'}[0] = "utc";
+---------------------------------------------------------------------------
++
+The example configuration presented here is guaranteed to be backwards
+and forward compatible.
++
+Time zone values can be "local" (for local time zone that browser uses), "utc"
+(what gitweb uses when JavaScript or this feature is disabled), or numerical
+time zones in the form of "+/-HHMM", such as "+0200".
++
+Project specific override is not supported.
+
+extra-branch-refs::
+	List of additional directories under "refs" which are going to
+	be used as branch refs. For example if you have a gerrit setup
+	where all branches under refs/heads/ are official,
+	push-after-review ones and branches under refs/sandbox/,
+	refs/wip and refs/other are user ones where permissions are
+	much wider, then you might want to set this variable as
+	follows:
++
+--------------------------------------------------------------------------------
+$feature{'extra-branch-refs'}{'default'} =
+	['sandbox', 'wip', 'other'];
+--------------------------------------------------------------------------------
++
+This feature can be configured on per-repository basis after setting
+$feature{'extra-branch-refs'}{'override'} to true, via repository's
+`gitweb.extraBranchRefs` configuration variable, which contains a
+space separated list of refs. An example:
++
+--------------------------------------------------------------------------------
+[gitweb]
+	extraBranchRefs = sandbox wip other
+--------------------------------------------------------------------------------
++
+The gitweb.extraBranchRefs is actually a multi-valued configuration
+variable, so following example is also correct and the result is the
+same as of the snippet above:
++
+--------------------------------------------------------------------------------
+[gitweb]
+	extraBranchRefs = sandbox
+	extraBranchRefs = wip other
+--------------------------------------------------------------------------------
++
+It is an error to specify a ref that does not pass "git check-ref-format"
+scrutiny. Duplicated values are filtered.
+
+
+EXAMPLES
+--------
+
+To enable blame, pickaxe search, and snapshot support (allowing "tar.gz" and
+"zip" snapshots), while allowing individual projects to turn them off, put
+the following in your GITWEB_CONFIG file:
+
+	$feature{'blame'}{'default'} = [1];
+	$feature{'blame'}{'override'} = 1;
+
+	$feature{'pickaxe'}{'default'} = [1];
+	$feature{'pickaxe'}{'override'} = 1;
+
+	$feature{'snapshot'}{'default'} = ['zip', 'tgz'];
+	$feature{'snapshot'}{'override'} = 1;
+
+If you allow overriding for the snapshot feature, you can specify which
+snapshot formats are globally disabled. You can also add any command-line
+options you want (such as setting the compression level). For instance, you
+can disable Zip compressed snapshots and set *gzip*(1) to run at level 6 by
+adding the following lines to your gitweb configuration file:
+
+	$known_snapshot_formats{'zip'}{'disabled'} = 1;
+	$known_snapshot_formats{'tgz'}{'compressor'} = ['gzip','-6'];
+
+BUGS
+----
+Debugging would be easier if the fallback configuration file
+(`/etc/gitweb.conf`) and environment variable to override its location
+('GITWEB_CONFIG_SYSTEM') had names reflecting their "fallback" role.
+The current names are kept to avoid breaking working setups.
+
+ENVIRONMENT
+-----------
+The location of per-instance and system-wide configuration files can be
+overridden using the following environment variables:
+
+GITWEB_CONFIG::
+	Sets location of per-instance configuration file.
+GITWEB_CONFIG_SYSTEM::
+	Sets location of fallback system-wide configuration file.
+	This file is read only if per-instance one does not exist.
+GITWEB_CONFIG_COMMON::
+	Sets location of common system-wide configuration file.
+
+
+FILES
+-----
+gitweb_config.perl::
+	This is default name of per-instance configuration file.  The
+	format of this file is described above.
+/etc/gitweb.conf::
+	This is default name of fallback system-wide configuration
+	file.  This file is used only if per-instance configuration
+	variable is not found.
+/etc/gitweb-common.conf::
+	This is default name of common system-wide configuration
+	file.

+NAME
+----
+gitweb - Git web interface (web frontend to Git repositories)
+
+SYNOPSIS
+--------
+To get started with gitweb, run linkgit:git-instaweb[1] from a Git repository.
+This would configure and start your web server, and run web browser pointing to
+gitweb.
+
+
+DESCRIPTION
+-----------
+Gitweb provides a web interface to Git repositories.  Its features include:
+
+* Viewing multiple Git repositories with common root.
+* Browsing every revision of the repository.
+* Viewing the contents of files in the repository at any revision.
+* Viewing the revision log of branches, history of files and directories,
+  see what was changed when, by who.
+* Viewing the blame/annotation details of any file (if enabled).
+* Generating RSS and Atom feeds of commits, for any branch.
+  The feeds are auto-discoverable in modern web browsers.
+* Viewing everything that was changed in a revision, and step through
+  revisions one at a time, viewing the history of the repository.
+* Finding commits which commit messages matches given search term.
+
+See http://git.kernel.org/?p=git/git.git;a=tree;f=gitweb[] or
+http://repo.or.cz/w/git.git/tree/HEAD:/gitweb/[] for gitweb source code,
+browsed using gitweb itself.
+
+
+CONFIGURATION
+-------------
+Various aspects of gitweb's behavior can be controlled through the configuration
+file 'gitweb_config.perl' or '/etc/gitweb.conf'.  See the linkgit:gitweb.conf[5]
+for details.
+
+Repositories
+~~~~~~~~~~~~
+Gitweb can show information from one or more Git repositories.  These
+repositories have to be all on local filesystem, and have to share common
+repository root, i.e. be all under a single parent repository (but see also
+"Advanced web server setup" section, "Webserver configuration with multiple
+projects' root" subsection).
+
+-----------------------------------------------------------------------
+our $projectroot = '/path/to/parent/directory';
+-----------------------------------------------------------------------
+
+The default value for `$projectroot` is '/pub/git'.  You can change it during
+building gitweb via `GITWEB_PROJECTROOT` build configuration variable.
+
+By default all Git repositories under `$projectroot` are visible and available
+to gitweb.  The list of projects is generated by default by scanning the
+`$projectroot` directory for Git repositories (for object databases to be
+more exact; gitweb is not interested in a working area, and is best suited
+to showing "bare" repositories).
+
+The name of the repository in gitweb is the path to its `$GIT_DIR` (its object
+database) relative to `$projectroot`.  Therefore the repository $repo can be
+found at "$projectroot/$repo".
+
+
+Projects list file format
+~~~~~~~~~~~~~~~~~~~~~~~~~
+Instead of having gitweb find repositories by scanning filesystem
+starting from $projectroot, you can provide a pre-generated list of
+visible projects by setting `$projects_list` to point to a plain text
+file with a list of projects (with some additional info).
+
+This file uses the following format:
+
+* One record (for project / repository) per line; does not support line
+continuation (newline escaping).
+
+* Leading and trailing whitespace are ignored.
+
+* Whitespace separated fields; any run of whitespace can be used as field
+separator (rules for Perl's "`split(" ", $line)`").
+
+* Fields use modified URI encoding, defined in RFC 3986, section 2.1
+(Percent-Encoding), or rather "Query string encoding" (see
+http://en.wikipedia.org/wiki/Query_string#URL_encoding[]), the difference
+being that SP (" ") can be encoded as "{plus}" (and therefore "{plus}" has to be
+also percent-encoded).
++
+Reserved characters are: "%" (used for encoding), "{plus}" (can be used to
+encode SPACE), all whitespace characters as defined in Perl, including SP,
+TAB and LF, (used to separate fields in a record).
+
+* Currently recognized fields are:
+<repository path>::
+	path to repository GIT_DIR, relative to `$projectroot`
+<repository owner>::
+	displayed as repository owner, preferably full name, or email,
+	or both
+
+You can generate the projects list index file using the project_index action
+(the 'TXT' link on projects list page) directly from gitweb; see also
+"Generating projects list using gitweb" section below.
+
+Example contents:
+-----------------------------------------------------------------------
+foo.git       Joe+R+Hacker+<joe@example.com>
+foo/bar.git   O+W+Ner+<owner@example.org>
+-----------------------------------------------------------------------
+
+
+By default this file controls only which projects are *visible* on projects
+list page (note that entries that do not point to correctly recognized Git
+repositories won't be displayed by gitweb).  Even if a project is not
+visible on projects list page, you can view it nevertheless by hand-crafting
+a gitweb URL.  By setting `$strict_export` configuration variable (see
+linkgit:gitweb.conf[5]) to true value you can allow viewing only of
+repositories also shown on the overview page (i.e. only projects explicitly
+listed in projects list file will be accessible).
+
+
+Generating projects list using gitweb
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+We assume that GITWEB_CONFIG has its default Makefile value, namely
+'gitweb_config.perl'. Put the following in 'gitweb_make_index.perl' file:
+----------------------------------------------------------------------------
+read_config_file("gitweb_config.perl");
+$projects_list = $projectroot;
+----------------------------------------------------------------------------
+
+Then create the following script to get list of project in the format
+suitable for GITWEB_LIST build configuration variable (or
+`$projects_list` variable in gitweb config):
+
+----------------------------------------------------------------------------
+#!/bin/sh
+
+export GITWEB_CONFIG="gitweb_make_index.perl"
+export GATEWAY_INTERFACE="CGI/1.1"
+export HTTP_ACCEPT="*/*"
+export REQUEST_METHOD="GET"
+export QUERY_STRING="a=project_index"
+
+perl -- /var/www/cgi-bin/gitweb.cgi
+----------------------------------------------------------------------------
+
+Run this script and save its output to a file.  This file could then be used
+as projects list file, which means that you can set `$projects_list` to its
+filename.
+
+
+Controlling access to Git repositories
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+By default all Git repositories under `$projectroot` are visible and
+available to gitweb.  You can however configure how gitweb controls access
+to repositories.
+
+* As described in "Projects list file format" section, you can control which
+projects are *visible* by selectively including repositories in projects
+list file, and setting `$projects_list` gitweb configuration variable to
+point to it.  With `$strict_export` set, projects list file can be used to
+control which repositories are *available* as well.
+
+* You can configure gitweb to only list and allow viewing of the explicitly
+exported repositories, via `$export_ok` variable in gitweb config file; see
+linkgit:gitweb.conf[5] manpage.  If it evaluates to true, gitweb shows
+repositories only if this file named by `$export_ok` exists in its object
+database (if directory has the magic file named `$export_ok`).
++
+For example linkgit:git-daemon[1] by default (unless `--export-all` option
+is used) allows pulling only for those repositories that have
+'git-daemon-export-ok' file.  Adding
++
+--------------------------------------------------------------------------
+our $export_ok = "git-daemon-export-ok";
+--------------------------------------------------------------------------
++
+makes gitweb show and allow access only to those repositories that can be
+fetched from via `git://` protocol.
+
+* Finally, it is possible to specify an arbitrary perl subroutine that will
+be called for each repository to determine if it can be exported.  The
+subroutine receives an absolute path to the project (repository) as its only
+parameter (i.e. "$projectroot/$project").
++
+For example, if you use mod_perl to run the script, and have dumb
+HTTP protocol authentication configured for your repositories, you
+can use the following hook to allow access only if the user is
+authorized to read the files:
++
+--------------------------------------------------------------------------
+$export_auth_hook = sub {
+	use Apache2::SubRequest ();
+	use Apache2::Const -compile => qw(HTTP_OK);
+	my $path = "$_[0]/HEAD";
+	my $r    = Apache2::RequestUtil->request;
+	my $sub  = $r->lookup_file($path);
+	return $sub->filename eq $path
+	    && $sub->status == Apache2::Const::HTTP_OK;
+};
+--------------------------------------------------------------------------
+
+
+Per-repository gitweb configuration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+You can configure individual repositories shown in gitweb by creating file
+in the 'GIT_DIR' of Git repository, or by setting some repo configuration
+variable (in 'GIT_DIR/config', see linkgit:git-config[1]).
+
+You can use the following files in repository:
+
+README.html::
+	A html file (HTML fragment) which is included on the gitweb project
+	"summary" page inside `<div>` block element. You can use it for longer
+	description of a project, to provide links (for example to project's
+	homepage), etc. This is recognized only if XSS prevention is off
+	(`$prevent_xss` is false, see linkgit:gitweb.conf[5]); a way to include
+	a README safely when XSS prevention is on may be worked out in the
+	future.
+
+description (or `gitweb.description`)::
+	Short (shortened to `$projects_list_description_width` in the projects
+	list page, which is 25 characters by default; see
+	linkgit:gitweb.conf[5]) single line description of a project (of a
+	repository).  Plain text file; HTML will be escaped.  By default set to
++
+-------------------------------------------------------------------------------
+Unnamed repository; edit this file to name it for gitweb.
+-------------------------------------------------------------------------------
++
+from the template during repository creation, usually installed in
+'/usr/share/git-core/templates/'.  You can use the `gitweb.description` repo
+configuration variable, but the file takes precedence.
+
+category (or `gitweb.category`)::
+	Singe line category of a project, used to group projects if
+	`$projects_list_group_categories` is enabled.  By default (file and
+	configuration variable absent), uncategorized projects are put in the
+	`$project_list_default_category` category.  You can use the
+	`gitweb.category` repo configuration variable, but the file takes
+	precedence.
++
+The configuration variables `$projects_list_group_categories` and
+`$project_list_default_category` are described in linkgit:gitweb.conf[5]
+
+cloneurl (or multiple-valued `gitweb.url`)::
+	File with repository URL (used for clone and fetch), one per line.
+	Displayed in the project summary page. You can use multiple-valued
+	`gitweb.url` repository configuration variable for that, but the file
+	takes precedence.
++
+This is per-repository enhancement / version of global prefix-based
+`@git_base_url_list` gitweb configuration variable (see
+linkgit:gitweb.conf[5]).
+
+gitweb.owner::
+	You can use the `gitweb.owner` repository configuration variable to set
+	repository's owner.  It is displayed in the project list and summary
+	page.
++
+If it's not set, filesystem directory's owner is used (via GECOS field,
+i.e. real name field from *getpwuid*(3)) if `$projects_list` is unset
+(gitweb scans `$projectroot` for repositories); if `$projects_list`
+points to file with list of repositories, then project owner defaults to
+value from this file for given repository.
+
+various `gitweb.*` config variables (in config)::
+	Read description of `%feature` hash for detailed list, and descriptions.
+	See also "Configuring gitweb features" section in linkgit:gitweb.conf[5]
+
+
+ACTIONS, AND URLS
+-----------------
+Gitweb can use path_info (component) based URLs, or it can pass all necessary
+information via query parameters.  The typical gitweb URLs are broken down in to
+five components:
+
+-----------------------------------------------------------------------
+.../gitweb.cgi/<repo>/<action>/<revision>:/<path>?<arguments>
+-----------------------------------------------------------------------
+
+repo::
+	The repository the action will be performed on.
++
+All actions except for those that list all available projects,
+in whatever form, require this parameter.
+
+action::
+	The action that will be run.  Defaults to 'projects_list' if repo
+	is not set, and to 'summary' otherwise.
+
+revision::
+	Revision shown.  Defaults to HEAD.
+
+path::
+	The path within the <repository> that the action is performed on,
+	for those actions that require it.
+
+arguments::
+	Any arguments that control the behaviour of the action.
+
+Some actions require or allow to specify two revisions, and sometimes even two
+pathnames.  In most general form such path_info (component) based gitweb URL
+looks like this:
+
+-----------------------------------------------------------------------
+.../gitweb.cgi/<repo>/<action>/<revision_from>:/<path_from>..<revision_to>:/<path_to>?<arguments>
+-----------------------------------------------------------------------
+
+
+Each action is implemented as a subroutine, and must be present in %actions
+hash.  Some actions are disabled by default, and must be turned on via feature
+mechanism.  For example to enable 'blame' view add the following to gitweb
+configuration file:
+
+-----------------------------------------------------------------------
+$feature{'blame'}{'default'} = [1];
+-----------------------------------------------------------------------
+
+
+Actions:
+~~~~~~~~
+The standard actions are:
+
+project_list::
+	Lists the available Git repositories.  This is the default command if no
+	repository is specified in the URL.
+
+summary::
+	Displays summary about given repository.  This is the default command if
+	no action is specified in URL, and only repository is specified.
+
+heads::
+remotes::
+	Lists all local or all remote-tracking branches in given repository.
++
+The latter is not available by default, unless configured.
+
+tags::
+	List all tags (lightweight and annotated) in given repository.
+
+blob::
+tree::
+	Shows the files and directories in a given repository path, at given
+	revision.  This is default command if no action is specified in the URL,
+	and path is given.
+
+blob_plain::
+	Returns the raw data for the file in given repository, at given path and
+	revision.  Links to this action are marked 'raw'.
+
+blobdiff::
+	Shows the difference between two revisions of the same file.
+
+blame::
+blame_incremental::
+	Shows the blame (also called annotation) information for a file. On a
+	per line basis it shows the revision in which that line was last changed
+	and the user that committed the change.  The incremental version (which
+	if configured is used automatically when JavaScript is enabled) uses
+	Ajax to incrementally add blame info to the contents of given file.
++
+This action is disabled by default for performance reasons.
+
+commit::
+commitdiff::
+	Shows information about a specific commit in a repository.  The 'commit'
+	view shows information about commit in more detail, the 'commitdiff'
+	action shows changeset for given commit.
+
+patch::
+	Returns the commit in plain text mail format, suitable for applying with
+	linkgit:git-am[1].
+
+tag::
+	Display specific annotated tag (tag object).
+
+log::
+shortlog::
+	Shows log information (commit message or just commit subject) for a
+	given branch (starting from given revision).
++
+The 'shortlog' view is more compact; it shows one commit per line.
+
+history::
+	Shows history of the file or directory in a given repository path,
+	starting from given revision (defaults to HEAD, i.e. default branch).
++
+This view is similar to 'shortlog' view.
+
+rss::
+atom::
+	Generates an RSS (or Atom) feed of changes to repository.
+
+
+WEBSERVER CONFIGURATION
+-----------------------
+This section explains how to configure some common webservers to run gitweb. In
+all cases, `/path/to/gitweb` in the examples is the directory you ran installed
+gitweb in, and contains `gitweb_config.perl`.
+
+If you've configured a web server that isn't listed here for gitweb, please send
+in the instructions so they can be included in a future release.
+
+Apache as CGI
+~~~~~~~~~~~~~
+Apache must be configured to support CGI scripts in the directory in
+which gitweb is installed.  Let's assume that it is '/var/www/cgi-bin'
+directory.
+
+-----------------------------------------------------------------------
+ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
+
+<Directory "/var/www/cgi-bin">
+    Options Indexes FollowSymlinks ExecCGI
+    AllowOverride None
+    Order allow,deny
+    Allow from all
+</Directory>
+-----------------------------------------------------------------------
+
+With that configuration the full path to browse repositories would be:
+
+  http://server/cgi-bin/gitweb.cgi
+
+Apache with mod_perl, via ModPerl::Registry
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+You can use mod_perl with gitweb.  You must install Apache::Registry
+(for mod_perl 1.x) or ModPerl::Registry (for mod_perl 2.x) to enable
+this support.
+
+Assuming that gitweb is installed to '/var/www/perl', the following
+Apache configuration (for mod_perl 2.x) is suitable.
+
+-----------------------------------------------------------------------
+Alias /perl "/var/www/perl"
+
+<Directory "/var/www/perl">
+    SetHandler perl-script
+    PerlResponseHandler ModPerl::Registry
+    PerlOptions +ParseHeaders
+    Options Indexes FollowSymlinks +ExecCGI
+    AllowOverride None
+    Order allow,deny
+    Allow from all
+</Directory>
+-----------------------------------------------------------------------
+
+With that configuration the full path to browse repositories would be:
+
+  http://server/perl/gitweb.cgi
+
+Apache with FastCGI
+~~~~~~~~~~~~~~~~~~~
+Gitweb works with Apache and FastCGI.  First you need to rename, copy
+or symlink gitweb.cgi to gitweb.fcgi.  Let's assume that gitweb is
+installed in '/usr/share/gitweb' directory.  The following Apache
+configuration is suitable (UNTESTED!)
+
+-----------------------------------------------------------------------
+FastCgiServer /usr/share/gitweb/gitweb.cgi
+ScriptAlias /gitweb /usr/share/gitweb/gitweb.cgi
+
+Alias /gitweb/static /usr/share/gitweb/static
+<Directory /usr/share/gitweb/static>
+    SetHandler default-handler
+</Directory>
+-----------------------------------------------------------------------
+
+With that configuration the full path to browse repositories would be:
+
+  http://server/gitweb
+
+
+ADVANCED WEB SERVER SETUP
+-------------------------
+All of those examples use request rewriting, and need `mod_rewrite`
+(or equivalent; examples below are written for Apache).
+
+Single URL for gitweb and for fetching
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+If you want to have one URL for both gitweb and your `http://`
+repositories, you can configure Apache like this:
+
+-----------------------------------------------------------------------
+<VirtualHost *:80>
+    ServerName    git.example.org
+    DocumentRoot  /pub/git
+    SetEnv        GITWEB_CONFIG   /etc/gitweb.conf
+
+    # turning on mod rewrite
+    RewriteEngine on
+
+    # make the front page an internal rewrite to the gitweb script
+    RewriteRule ^/$  /cgi-bin/gitweb.cgi
+
+    # make access for "dumb clients" work
+    RewriteRule ^/(.*\.git/(?!/?(HEAD|info|objects|refs)).*)?$ \
+		/cgi-bin/gitweb.cgi%{REQUEST_URI}  [L,PT]
+</VirtualHost>
+-----------------------------------------------------------------------
+
+The above configuration expects your public repositories to live under
+'/pub/git' and will serve them as `http://git.domain.org/dir-under-pub-git`,
+both as clonable Git URL and as browseable gitweb interface.  If you then
+start your linkgit:git-daemon[1] with `--base-path=/pub/git --export-all`
+then you can even use the `git://` URL with exactly the same path.
+
+Setting the environment variable `GITWEB_CONFIG` will tell gitweb to use the
+named file (i.e. in this example '/etc/gitweb.conf') as a configuration for
+gitweb.  You don't really need it in above example; it is required only if
+your configuration file is in different place than built-in (during
+compiling gitweb) 'gitweb_config.perl' or '/etc/gitweb.conf'.  See
+linkgit:gitweb.conf[5] for details, especially information about precedence
+rules.
+
+If you use the rewrite rules from the example you *might* also need
+something like the following in your gitweb configuration file
+('/etc/gitweb.conf' following example):
+----------------------------------------------------------------------------
+@stylesheets = ("/some/absolute/path/gitweb.css");
+$my_uri    = "/";
+$home_link = "/";
+$per_request_config = 1;
+----------------------------------------------------------------------------
+Nowadays though gitweb should create HTML base tag when needed (to set base
+URI for relative links), so it should work automatically.
+
+
+Webserver configuration with multiple projects' root
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+If you want to use gitweb with several project roots you can edit your
+Apache virtual host and gitweb configuration files in the following way.
+
+The virtual host configuration (in Apache configuration file) should look
+like this:
+--------------------------------------------------------------------------
+<VirtualHost *:80>
+    ServerName    git.example.org
+    DocumentRoot  /pub/git
+    SetEnv        GITWEB_CONFIG  /etc/gitweb.conf
+
+    # turning on mod rewrite
+    RewriteEngine on
+
+    # make the front page an internal rewrite to the gitweb script
+    RewriteRule ^/$  /cgi-bin/gitweb.cgi  [QSA,L,PT]
+
+    # look for a public_git folder in unix users' home
+    # http://git.example.org/~<user>/
+    RewriteRule ^/\~([^\/]+)(/|/gitweb.cgi)?$	/cgi-bin/gitweb.cgi \
+		[QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT]
+
+    # http://git.example.org/+<user>/
+    #RewriteRule ^/\+([^\/]+)(/|/gitweb.cgi)?$	/cgi-bin/gitweb.cgi \
+		 [QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT]
+
+    # http://git.example.org/user/<user>/
+    #RewriteRule ^/user/([^\/]+)/(gitweb.cgi)?$	/cgi-bin/gitweb.cgi \
+		 [QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT]
+
+    # defined list of project roots
+    RewriteRule ^/scm(/|/gitweb.cgi)?$ /cgi-bin/gitweb.cgi \
+		[QSA,E=GITWEB_PROJECTROOT:/pub/scm/,L,PT]
+    RewriteRule ^/var(/|/gitweb.cgi)?$ /cgi-bin/gitweb.cgi \
+		[QSA,E=GITWEB_PROJECTROOT:/var/git/,L,PT]
+
+    # make access for "dumb clients" work
+    RewriteRule ^/(.*\.git/(?!/?(HEAD|info|objects|refs)).*)?$ \
+		/cgi-bin/gitweb.cgi%{REQUEST_URI}  [L,PT]
+</VirtualHost>
+--------------------------------------------------------------------------
+
+Here actual project root is passed to gitweb via `GITWEB_PROJECT_ROOT`
+environment variable from a web server, so you need to put the following
+line in gitweb configuration file ('/etc/gitweb.conf' in above example):
+--------------------------------------------------------------------------
+$projectroot = $ENV{'GITWEB_PROJECTROOT'} || "/pub/git";
+--------------------------------------------------------------------------
+*Note* that this requires to be set for each request, so either
+`$per_request_config` must be false, or the above must be put in code
+referenced by `$per_request_config`;
+
+These configurations enable two things. First, each unix user (`<user>`) of
+the server will be able to browse through gitweb Git repositories found in
+'~/public_git/' with the following url:
+
+  http://git.example.org/~<user>/
+
+If you do not want this feature on your server just remove the second
+rewrite rule.
+
+If you already use `mod_userdir` in your virtual host or you don't want to
+use the \'~' as first character, just comment or remove the second rewrite
+rule, and uncomment one of the following according to what you want.
+
+Second, repositories found in '/pub/scm/' and '/var/git/' will be accessible
+through `http://git.example.org/scm/` and `http://git.example.org/var/`.
+You can add as many project roots as you want by adding rewrite rules like
+the third and the fourth.
+
+
+PATH_INFO usage
+~~~~~~~~~~~~~~~
+If you enable PATH_INFO usage in gitweb by putting
+----------------------------------------------------------------------------
+$feature{'pathinfo'}{'default'} = [1];
+----------------------------------------------------------------------------
+in your gitweb configuration file, it is possible to set up your server so
+that it consumes and produces URLs in the form
+
+  http://git.example.com/project.git/shortlog/sometag
+
+i.e. without 'gitweb.cgi' part, by using a configuration such as the
+following.  This configuration assumes that '/var/www/gitweb' is the
+DocumentRoot of your webserver, contains the gitweb.cgi script and
+complementary static files (stylesheet, favicon, JavaScript):
+
+----------------------------------------------------------------------------
+<VirtualHost *:80>
+	ServerAlias git.example.com
+
+	DocumentRoot /var/www/gitweb
+
+	<Directory /var/www/gitweb>
+		Options ExecCGI
+		AddHandler cgi-script cgi
+
+		DirectoryIndex gitweb.cgi
+
+		RewriteEngine On
+		RewriteCond %{REQUEST_FILENAME} !-f
+		RewriteCond %{REQUEST_FILENAME} !-d
+		RewriteRule ^.* /gitweb.cgi/$0 [L,PT]
+	</Directory>
+</VirtualHost>
+----------------------------------------------------------------------------
+The rewrite rule guarantees that existing static files will be properly
+served, whereas any other URL will be passed to gitweb as PATH_INFO
+parameter.
+
+*Notice* that in this case you don't need special settings for
+`@stylesheets`, `$my_uri` and `$home_link`, but you lose "dumb client"
+access to your project .git dirs (described in "Single URL for gitweb and
+for fetching" section).  A possible workaround for the latter is the
+following: in your project root dir (e.g. '/pub/git') have the projects
+named *without* a .git extension (e.g. '/pub/git/project' instead of
+'/pub/git/project.git') and configure Apache as follows:
+----------------------------------------------------------------------------
+<VirtualHost *:80>
+	ServerAlias git.example.com
+
+	DocumentRoot /var/www/gitweb
+
+	AliasMatch ^(/.*?)(\.git)(/.*)?$ /pub/git$1$3
+	<Directory /var/www/gitweb>
+		Options ExecCGI
+		AddHandler cgi-script cgi
+
+		DirectoryIndex gitweb.cgi
+
+		RewriteEngine On
+		RewriteCond %{REQUEST_FILENAME} !-f
+		RewriteCond %{REQUEST_FILENAME} !-d
+		RewriteRule ^.* /gitweb.cgi/$0 [L,PT]
+	</Directory>
+</VirtualHost>
+----------------------------------------------------------------------------
+
+The additional AliasMatch makes it so that
+
+  http://git.example.com/project.git
+
+will give raw access to the project's Git dir (so that the project can be
+cloned), while
+
+  http://git.example.com/project
+
+will provide human-friendly gitweb access.
+
+This solution is not 100% bulletproof, in the sense that if some project has
+a named ref (branch, tag) starting with 'git/', then paths such as
+
+  http://git.example.com/project/command/abranch..git/abranch
+
+will fail with a 404 error.

+Branch management for a release
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Assuming you are using the merge approach discussed above, when you
+are releasing your project you will need to do some additional branch
+management work.
+
+A feature release is created from the 'master' branch, since 'master'
+tracks the commits that should go into the next feature release.
+
+The 'master' branch is supposed to be a superset of 'maint'. If this
+condition does not hold, then 'maint' contains some commits that
+are not included on 'master'. The fixes represented by those commits
+will therefore not be included in your feature release.
+
+To verify that 'master' is indeed a superset of 'maint', use git log:
+
+.Verify 'master' is a superset of 'maint'
+[caption="Recipe: "]
+=====================================
+`git log master..maint`
+=====================================
+
+This command should not list any commits.  Otherwise, check out
+'master' and merge 'maint' into it.
+
+Now you can proceed with the creation of the feature release. Apply a
+tag to the tip of 'master' indicating the release version:
+
+.Release tagging
+[caption="Recipe: "]
+=====================================
+`git tag -s -m "Git X.Y.Z" vX.Y.Z master`
+=====================================
+
+You need to push the new tag to a public Git server (see
+"DISTRIBUTED WORKFLOWS" below). This makes the tag available to
+others tracking your project. The push could also trigger a
+post-update hook to perform release-related items such as building
+release tarballs and preformatted documentation pages.
+
+Similarly, for a maintenance release, 'maint' is tracking the commits
+to be released. Therefore, in the steps above simply tag and push
+'maint' rather than 'master'.
+
+
+Maintenance branch management after a feature release
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+After a feature release, you need to manage your maintenance branches.
+
+First, if you wish to continue to release maintenance fixes for the
+feature release made before the recent one, then you must create
+another branch to track commits for that previous release.
+
+To do this, the current maintenance branch is copied to another branch
+named with the previous release version number (e.g. maint-X.Y.(Z-1)
+where X.Y.Z is the current release).
+
+.Copy maint
+[caption="Recipe: "]
+=====================================
+`git branch maint-X.Y.(Z-1) maint`
+=====================================
+
+The 'maint' branch should now be fast-forwarded to the newly released
+code so that maintenance fixes can be tracked for the current release:
+
+.Update maint to new release
+[caption="Recipe: "]
+=====================================
+* `git checkout maint`
+* `git merge --ff-only master`
+=====================================
+
+If the merge fails because it is not a fast-forward, then it is
+possible some fixes on 'maint' were missed in the feature release.
+This will not happen if the content of the branches was verified as
+described in the previous section.
+
+
+Branch management for next and pu after a feature release
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+After a feature release, the integration branch 'next' may optionally be
+rewound and rebuilt from the tip of 'master' using the surviving
+topics on 'next':
+
+.Rewind and rebuild next
+[caption="Recipe: "]
+=====================================
+* `git checkout next`
+* `git reset --hard master`
+* `git merge ai/topic_in_next1`
+* `git merge ai/topic_in_next2`
+* ...
+=====================================
+
+The advantage of doing this is that the history of 'next' will be
+clean. For example, some topics merged into 'next' may have initially
+looked promising, but were later found to be undesirable or premature.
+In such a case, the topic is reverted out of 'next' but the fact
+remains in the history that it was once merged and reverted. By
+recreating 'next', you give another incarnation of such topics a clean
+slate to retry, and a feature release is a good point in history to do
+so.
+
+If you do this, then you should make a public announcement indicating
+that 'next' was rewound and rebuilt.
+
+The same rewind and rebuild process may be followed for 'pu'. A public
+announcement is not necessary since 'pu' is a throw-away branch, as
+described above.

+[[def_pathspec]]pathspec::
+	Pattern used to limit paths in Git commands.
++
+Pathspecs are used on the command line of "git ls-files", "git
+ls-tree", "git add", "git grep", "git diff", "git checkout",
+and many other commands to
+limit the scope of operations to some subset of the tree or
+worktree.  See the documentation of each command for whether
+paths are relative to the current directory or toplevel.  The
+pathspec syntax is as follows:
++
+--
+
+* any path matches itself
+* the pathspec up to the last slash represents a
+  directory prefix.  The scope of that pathspec is
+  limited to that subtree.
+* the rest of the pathspec is a pattern for the remainder
+  of the pathname.  Paths relative to the directory
+  prefix will be matched against that pattern using fnmatch(3);
+  in particular, '*' and '?' _can_ match directory separators.
+
+--
++
+For example, Documentation/*.jpg will match all .jpg files
+in the Documentation subtree,
+including Documentation/chapter_1/figure_1.jpg.
++
+A pathspec that begins with a colon `:` has special meaning.  In the
+short form, the leading colon `:` is followed by zero or more "magic
+signature" letters (which optionally is terminated by another colon `:`),
+and the remainder is the pattern to match against the path.
+The "magic signature" consists of ASCII symbols that are neither
+alphanumeric, glob, regex special characters nor colon.
+The optional colon that terminates the "magic signature" can be
+omitted if the pattern begins with a character that does not belong to
+"magic signature" symbol set and is not a colon.
++
+In the long form, the leading colon `:` is followed by a open
+parenthesis `(`, a comma-separated list of zero or more "magic words",
+and a close parentheses `)`, and the remainder is the pattern to match
+against the path.
++
+A pathspec with only a colon means "there is no pathspec". This form
+should not be combined with other pathspec.
++
+--
+top;;
+	The magic word `top` (magic signature: `/`) makes the pattern
+	match from the root of the working tree, even when you are
+	running the command from inside a subdirectory.
+
+literal;;
+	Wildcards in the pattern such as `*` or `?` are treated
+	as literal characters.
+
+icase;;
+	Case insensitive match.
+
+glob;;
+	Git treats the pattern as a shell glob suitable for
+	consumption by fnmatch(3) with the FNM_PATHNAME flag:
+	wildcards in the pattern will not match a / in the pathname.
+	For example, "Documentation/{asterisk}.html" matches
+	"Documentation/git.html" but not "Documentation/ppc/ppc.html"
+	or "tools/perf/Documentation/perf.html".
++
+Two consecutive asterisks ("`**`") in patterns matched against
+full pathname may have special meaning:
+
+ - A leading "`**`" followed by a slash means match in all
+   directories. For example, "`**/foo`" matches file or directory
+   "`foo`" anywhere, the same as pattern "`foo`". "`**/foo/bar`"
+   matches file or directory "`bar`" anywhere that is directly
+   under directory "`foo`".
+
+ - A trailing "`/**`" matches everything inside. For example,
+   "`abc/**`" matches all files inside directory "abc", relative
+   to the location of the `.gitignore` file, with infinite depth.
+
+ - A slash followed by two consecutive asterisks then a slash
+   matches zero or more directories. For example, "`a/**/b`"
+   matches "`a/b`", "`a/x/b`", "`a/x/y/b`" and so on.
+
+ - Other consecutive asterisks are considered invalid.
++
+Glob magic is incompatible with literal magic.
+
+exclude;;
+	After a path matches any non-exclude pathspec, it will be run
+	through all exclude pathspec (magic signature: `!`). If it
+	matches, the path is ignored.

+Subject: Beginner question on "Pull is mostly evil"
+Abstract: This how-to explains a method for keeping a
+ project's history correct when using git pull.
+Content-type: text/asciidoc
+
+Keep authoritative canonical history correct with git pull
+==========================================================
+
+Sometimes a new project integrator will end up with project history
+that appears to be "backwards" from what other project developers
+expect. This howto presents a suggested integration workflow for
+maintaining a central repository.
+
+Suppose that that central repository has this history:
+
+------------
+    ---o---o---A
+------------
+
+which ends at commit `A` (time flows from left to right and each node
+in the graph is a commit, lines between them indicating parent-child
+relationship).
+
+Then you clone it and work on your own commits, which leads you to
+have this history in *your* repository:
+
+------------
+    ---o---o---A---B---C
+------------
+
+Imagine your coworker did the same and built on top of `A` in *his*
+repository in the meantime, and then pushed it to the
+central repository:
+
+------------
+    ---o---o---A---X---Y---Z
+------------
+
+Now, if you `git push` at this point, because your history that leads
+to `C` lacks `X`, `Y` and `Z`, it will fail.  You need to somehow make
+the tip of your history a descendant of `Z`.
+
+One suggested way to solve the problem is "fetch and then merge", aka
+`git pull`. When you fetch, your repository will have a history like
+this:
+
+------------
+    ---o---o---A---B---C
+		\
+		 X---Y---Z
+------------
+
+Once you run merge after that, while still on *your* branch, i.e. `C`,
+you will create a merge `M` and make the history look like this:
+
+------------
+    ---o---o---A---B---C---M
+		\         /
+		 X---Y---Z
+------------
+
+`M` is a descendant of `Z`, so you can push to update the central
+repository.  Such a merge `M` does not lose any commit in both
+histories, so in that sense it may not be wrong, but when people want
+to talk about "the authoritative canonical history that is shared
+among the project participants", i.e. "the trunk", they often view
+it as "commits you see by following the first-parent chain", and use
+this command to view it:
+
+------------
+    $ git log --first-parent
+------------
+
+For all other people who observed the central repository after your
+coworker pushed `Z` but before you pushed `M`, the commit on the trunk
+used to be `o-o-A-X-Y-Z`.  But because you made `M` while you were on
+`C`, `M`'s first parent is `C`, so by pushing `M` to advance the
+central repository, you made `X-Y-Z` a side branch, not on the trunk.
+
+You would rather want to have a history of this shape:
+
+------------
+    ---o---o---A---X---Y---Z---M'
+		\             /
+		 B-----------C
+------------
+
+so that in the first-parent chain, it is clear that the project first
+did `X` and then `Y` and then `Z` and merged a change that consists of
+two commits `B` and `C` that achieves a single goal.  You may have
+worked on fixing the bug #12345 with these two patches, and the merge
+`M'` with swapped parents can say in its log message "Merge
+fix-bug-12345". Having a way to tell `git pull` to create a merge
+but record the parents in reverse order may be a way to do so.
+
+Note that I said "achieves a single goal" above, because this is
+important.  "Swapping the merge order" only covers a special case
+where the project does not care too much about having unrelated
+things done on a single merge but cares a lot about first-parent
+chain.
+
+There are multiple schools of thought about the "trunk" management.
+
+ 1. Some projects want to keep a completely linear history without any
+    merges.  Obviously, swapping the merge order would not match their
+    taste.  You would need to flatten your history on top of the
+    updated upstream to result in a history of this shape instead:
++
+------------
+    ---o---o---A---X---Y---Z---B---C
+------------
++
+with `git pull --rebase` or something.
+
+ 2. Some projects tolerate merges in their history, but do not worry
+    too much about the first-parent order, and allow fast-forward
+    merges.  To them, swapping the merge order does not hurt, but
+    it is unnecessary.
+
+ 3. Some projects want each commit on the "trunk" to do one single
+    thing.  The output of `git log --first-parent` in such a project
+    would show either a merge of a side branch that completes a single
+    theme, or a single commit that completes a single theme by itself.
+    If your two commits `B` and `C` (or they may even be two groups of
+    commits) were solving two independent issues, then the merge `M'`
+    we made in the earlier example by swapping the merge order is
+    still not up to the project standard.  It merges two unrelated
+    efforts `B` and `C` at the same time.
+
+For projects in the last category (Git itself is one of them),
+individual developers would want to prepare a history more like
+this:
+
+------------
+		 C0--C1--C2     topic-c
+		/
+    ---o---o---A                master
+		\
+		 B0--B1--B2     topic-b
+------------
+
+That is, keeping separate topics on separate branches, perhaps like
+so:
+
+------------
+    $ git clone $URL work && cd work
+    $ git checkout -b topic-b master
+    $ ... work to create B0, B1 and B2 to complete one theme
+    $ git checkout -b topic-c master
+    $ ... same for the theme of topic-c
+------------
+
+And then
+
+------------
+    $ git checkout master
+    $ git pull --ff-only
+------------
+
+would grab `X`, `Y` and `Z` from the upstream and advance your master
+branch:
+
+------------
+		 C0--C1--C2     topic-c
+		/
+    ---o---o---A---X---Y---Z    master
+		\
+		 B0--B1--B2     topic-b
+------------
+
+And then you would merge these two branches separately:
+
+------------
+    $ git merge topic-b
+    $ git merge topic-c
+------------
+
+to result in
+
+------------
+		 C0--C1---------C2
+		/                 \
+    ---o---o---A---X---Y---Z---M---N
+		\             /
+		 B0--B1-----B2
+------------
+
+and push it back to the central repository.
+
+It is very much possible that while you are merging topic-b and
+topic-c, somebody again advanced the history in the central repository
+to put `W` on top of `Z`, and make your `git push` fail.
+
+In such a case, you would rewind to discard `M` and `N`, update the
+tip of your 'master' again and redo the two merges:
+
+------------
+    $ git reset --hard origin/master
+    $ git pull --ff-only
+    $ git merge topic-b
+    $ git merge topic-c
+------------
+
+The procedure will result in a history that looks like this:
+
+------------
+		 C0--C1--------------C2
+		/                     \
+    ---o---o---A---X---Y---Z---W---M'--N'
+		\                 /
+		 B0--B1---------B2
+------------

+Appendix
+--------
+
+Preparing a "merge-fix"
+~~~~~~~~~~~~~~~~~~~~~~~
+
+A merge of two topics may not textually conflict but still have
+conflict at the semantic level. A classic example is for one topic
+to rename an variable and all its uses, while another topic adds a
+new use of the variable under its old name. When these two topics
+are merged together, the reference to the variable newly added by
+the latter topic will still use the old name in the result.
+
+The Meta/Reintegrate script that is used by redo-jch and redo-pu
+scripts implements a crude but usable way to work this issue around.
+When the script merges branch $X, it checks if "refs/merge-fix/$X"
+exists, and if so, the effect of it is squashed into the result of
+the mechanical merge.  In other words,
+
+     $ echo $X | Meta/Reintegrate
+
+is roughly equivalent to this sequence:
+
+     $ git merge --rerere-autoupdate $X
+     $ git commit
+     $ git cherry-pick -n refs/merge-fix/$X
+     $ git commit --amend
+
+The goal of this "prepare a merge-fix" step is to come up with a
+commit that can be squashed into a result of mechanical merge to
+correct semantic conflicts.
+
+After finding that the result of merging branch "ai/topic" to an
+integration branch had such a semantic conflict, say pu~4, check the
+problematic merge out on a detached HEAD, edit the working tree to
+fix the semantic conflict, and make a separate commit to record the
+fix-up:
+
+     $ git checkout pu~4
+     $ git show -s --pretty=%s ;# double check
+     Merge branch 'ai/topic' to pu
+     $ edit
+     $ git commit -m 'merge-fix/ai/topic' -a
+
+Then make a reference "refs/merge-fix/ai/topic" to point at this
+result:
+
+     $ git update-ref refs/merge-fix/ai/topic HEAD
+
+Then double check the result by asking Meta/Reintegrate to redo the
+merge:
+
+     $ git checkout pu~5 ;# the parent of the problem merge
+     $ echo ai/topic | Meta/Reintegrate
+     $ git diff pu~4
+
+This time, because you prepared refs/merge-fix/ai/topic, the
+resulting merge should have been tweaked to include the fix for the
+semantic conflict.
+
+Note that this assumes that the order in which conflicting branches
+are merged does not change.  If the reason why merging ai/topic
+branch needs this merge-fix is because another branch merged earlier
+to the integration branch changed the underlying assumption ai/topic
+branch made (e.g. ai/topic branch added a site to refer to a
+variable, while the other branch renamed that variable and adjusted
+existing use sites), and if you changed redo-jch (or redo-pu) script
+to merge ai/topic branch before the other branch, then the above
+merge-fix should not be applied while merging ai/topic, but should
+instead be applied while merging the other branch.  You would need
+to move the fix to apply to the other branch, perhaps like this:
+
+      $ mf=refs/merge-fix
+      $ git update-ref $mf/$the_other_branch $mf/ai/topic
+      $ git update-ref -d $mf/ai/topic

+Abstract: This is how-to documentation for people who want to add extension
+ commands to Git.  It should be read alongside api-builtin.txt.
+Content-type: text/asciidoc
+
+How to integrate new subcommands
+================================
+
+This is how-to documentation for people who want to add extension
+commands to Git.  It should be read alongside api-builtin.txt.
+
+Runtime environment
+-------------------
+
+Git subcommands are standalone executables that live in the Git exec
+path, normally /usr/lib/git-core.  The git executable itself is a
+thin wrapper that knows where the subcommands live, and runs them by
+passing command-line arguments to them.
+
+(If "git foo" is not found in the Git exec path, the wrapper
+will look in the rest of your $PATH for it.  Thus, it's possible
+to write local Git extensions that don't live in system space.)
+
+Implementation languages
+------------------------
+
+Most subcommands are written in C or shell.  A few are written in
+Perl.
+
+While we strongly encourage coding in portable C for portability,
+these specific scripting languages are also acceptable.  We won't
+accept more without a very strong technical case, as we don't want
+to broaden the Git suite's required dependencies.  Import utilities,
+surgical tools, remote helpers and other code at the edges of the
+Git suite are more lenient and we allow Python (and even Tcl/tk),
+but they should not be used for core functions.
+
+This may change in the future.  Especially Python is not allowed in
+core because we need better Python integration in the Git Windows
+installer before we can be confident people in that environment
+won't experience an unacceptably large loss of capability.
+
+C commands are normally written as single modules, named after the
+command, that link a collection of functions called libgit.  Thus,
+your command 'git-foo' would normally be implemented as a single
+"git-foo.c" (or "builtin/foo.c" if it is to be linked to the main
+binary); this organization makes it easy for people reading the code
+to find things.
+
+See the CodingGuidelines document for other guidance on what we consider
+good practice in C and shell, and api-builtin.txt for the support
+functions available to built-in commands written in C.
+
+What every extension command needs
+----------------------------------
+
+You must have a man page, written in asciidoc (this is what Git help
+followed by your subcommand name will display).  Be aware that there is
+a local asciidoc configuration and macros which you should use.  It's
+often helpful to start by cloning an existing page and replacing the
+text content.
+
+You must have a test, written to report in TAP (Test Anything Protocol).
+Tests are executables (usually shell scripts) that live in the 't'
+subdirectory of the tree.  Each test name begins with 't' and a sequence
+number that controls where in the test sequence it will be executed;
+conventionally the rest of the name stem is that of the command
+being tested.
+
+Read the file t/README to learn more about the conventions to be used
+in writing tests, and the test support library.
+
+Integrating a command
+---------------------
+
+Here are the things you need to do when you want to merge a new
+subcommand into the Git tree.
+
+1. Don't forget to sign off your patch!
+
+2. Append your command name to one of the variables BUILTIN_OBJS,
+EXTRA_PROGRAMS, SCRIPT_SH, SCRIPT_PERL or SCRIPT_PYTHON.
+
+3. Drop its test in the t directory.
+
+4. If your command is implemented in an interpreted language with a
+p-code intermediate form, make sure .gitignore in the main directory
+includes a pattern entry that ignores such files.  Python .pyc and
+.pyo files will already be covered.
+
+5. If your command has any dependency on a particular version of
+your language, document it in the INSTALL file.
+
+6. There is a file command-list.txt in the distribution main directory
+that categorizes commands by type, so they can be listed in appropriate
+subsections in the documentation's summary command list.  Add an entry
+for yours.  To understand the categories, look at git-commands.txt
+in the main directory.
+
+7. Give the maintainer one paragraph to include in the RelNotes file
+to describe the new feature; a good place to do so is in the cover
+letter [PATCH 0/n].
+
+That's all there is to it.

+Subject: pack corruption post-mortem
+Abstract: Recovering a corrupted object when no good copy is available.
+Content-type: text/asciidoc
+
+How to recover an object from scratch
+=====================================
+
+I was recently presented with a repository with a corrupted packfile,
+and was asked if the data was recoverable. This post-mortem describes
+the steps I took to investigate and fix the problem. I thought others
+might find the process interesting, and it might help somebody in the
+same situation.
+
+********************************
+Note: In this case, no good copy of the repository was available. For
+the much easier case where you can get the corrupted object from
+elsewhere, see link:recover-corrupted-blob-object.html[this howto].
+********************************
+
+I started with an fsck, which found a problem with exactly one object
+(I've used $pack and $obj below to keep the output readable, and also
+because I'll refer to them later):
+
+-----------
+    $ git fsck
+    error: $pack SHA1 checksum mismatch
+    error: index CRC mismatch for object $obj from $pack at offset 51653873
+    error: inflate: data stream error (incorrect data check)
+    error: cannot unpack $obj from $pack at offset 51653873
+-----------
+
+The pack checksum failing means a byte is munged somewhere, and it is
+presumably in the object mentioned (since both the index checksum and
+zlib were failing).
+
+Reading the zlib source code, I found that "incorrect data check" means
+that the adler-32 checksum at the end of the zlib data did not match the
+inflated data. So stepping the data through zlib would not help, as it
+did not fail until the very end, when we realize the CRC does not match.
+The problematic bytes could be anywhere in the object data.
+
+The first thing I did was pull the broken data out of the packfile. I
+needed to know how big the object was, which I found out with:
+
+------------
+    $ git show-index <$idx | cut -d' ' -f1 | sort -n | grep -A1 51653873
+    51653873
+    51664736
+------------
+
+Show-index gives us the list of objects and their offsets. We throw away
+everything but the offsets, and then sort them so that our interesting
+offset (which we got from the fsck output above) is followed immediately
+by the offset of the next object. Now we know that the object data is
+10863 bytes long, and we can grab it with:
+
+------------
+  dd if=$pack of=object bs=1 skip=51653873 count=10863
+------------
+
+I inspected a hexdump of the data, looking for any obvious bogosity
+(e.g., a 4K run of zeroes would be a good sign of filesystem
+corruption). But everything looked pretty reasonable.
+
+Note that the "object" file isn't fit for feeding straight to zlib; it
+has the git packed object header, which is variable-length. We want to
+strip that off so we can start playing with the zlib data directly. You
+can either work your way through it manually (the format is described in
+link:../technical/pack-format.html[Documentation/technical/pack-format.txt]),
+or you can walk through it in a debugger. I did the latter, creating a
+valid pack like:
+
+------------
+    # pack magic and version
+    printf 'PACK\0\0\0\2' >tmp.pack
+    # pack has one object
+    printf '\0\0\0\1' >>tmp.pack
+    # now add our object data
+    cat object >>tmp.pack
+    # and then append the pack trailer
+    /path/to/git.git/test-sha1 -b <tmp.pack >trailer
+    cat trailer >>tmp.pack
+------------
+
+and then running "git index-pack tmp.pack" in the debugger (stop at
+unpack_raw_entry). Doing this, I found that there were 3 bytes of header
+(and the header itself had a sane type and size). So I stripped those
+off with:
+
+------------
+    dd if=object of=zlib bs=1 skip=3
+------------
+
+I ran the result through zlib's inflate using a custom C program. And
+while it did report the error, I did get the right number of output
+bytes (i.e., it matched git's size header that we decoded above). But
+feeding the result back to "git hash-object" didn't produce the same
+sha1. So there were some wrong bytes, but I didn't know which. The file
+happened to be C source code, so I hoped I could notice something
+obviously wrong with it, but I didn't. I even got it to compile!
+
+I also tried comparing it to other versions of the same path in the
+repository, hoping that there would be some part of the diff that didn't
+make sense. Unfortunately, this happened to be the only revision of this
+particular file in the repository, so I had nothing to compare against.
+
+So I took a different approach. Working under the guess that the
+corruption was limited to a single byte, I wrote a program to munge each
+byte individually, and try inflating the result. Since the object was
+only 10K compressed, that worked out to about 2.5M attempts, which took
+a few minutes.
+
+The program I used is here:
+
+----------------------------------------------
+#include <stdio.h>
+#include <unistd.h>
+#include <string.h>
+#include <signal.h>
+#include <zlib.h>
+
+static int try_zlib(unsigned char *buf, int len)
+{
+	/* make this absurdly large so we don't have to loop */
+	static unsigned char out[1024*1024];
+	z_stream z;
+	int ret;
+
+	memset(&z, 0, sizeof(z));
+	inflateInit(&z);
+
+	z.next_in = buf;
+	z.avail_in = len;
+	z.next_out = out;
+	z.avail_out = sizeof(out);
+
+	ret = inflate(&z, 0);
+	inflateEnd(&z);
+	return ret >= 0;
+}
+
+/* eye candy */
+static int counter = 0;
+static void progress(int sig)
+{
+	fprintf(stderr, "\r%d", counter);
+	alarm(1);
+}
+
+int main(void)
+{
+	/* oversized so we can read the whole buffer in */
+	unsigned char buf[1024*1024];
+	int len;
+	unsigned i, j;
+
+	signal(SIGALRM, progress);
+	alarm(1);
+
+	len = read(0, buf, sizeof(buf));
+	for (i = 0; i < len; i++) {
+		unsigned char c = buf[i];
+		for (j = 0; j <= 0xff; j++) {
+			buf[i] = j;
+
+			counter++;
+			if (try_zlib(buf, len))
+				printf("i=%d, j=%x\n", i, j);
+		}
+		buf[i] = c;
+	}
+
+	alarm(0);
+	fprintf(stderr, "\n");
+	return 0;
+}
+----------------------------------------------
+
+I compiled and ran with:
+
+-------
+  gcc -Wall -Werror -O3 munge.c -o munge -lz
+  ./munge <zlib
+-------
+
+
+There were a few false positives early on (if you write "no data" in the
+zlib header, zlib thinks it's just fine :) ). But I got a hit about
+halfway through:
+
+-------
+  i=5642, j=c7
+-------
+
+I let it run to completion, and got a few more hits at the end (where it
+was munging the CRC to match our broken data). So there was a good
+chance this middle hit was the source of the problem.
+
+I confirmed by tweaking the byte in a hex editor, zlib inflating the
+result (no errors!), and then piping the output into "git hash-object",
+which reported the sha1 of the broken object. Success!
+
+I fixed the packfile itself with:
+
+-------
+  chmod +w $pack
+  printf '\xc7' | dd of=$pack bs=1 seek=51659518 conv=notrunc
+  chmod -w $pack
+-------
+
+The `\xc7` comes from the replacement byte our "munge" program found.
+The offset 51659518 is derived by taking the original object offset
+(51653873), adding the replacement offset found by "munge" (5642), and
+then adding back in the 3 bytes of git header we stripped.
+
+After that, "git fsck" ran clean.
+
+As for the corruption itself, I was lucky that it was indeed a single
+byte. In fact, it turned out to be a single bit. The byte 0xc7 was
+corrupted to 0xc5. So presumably it was caused by faulty hardware, or a
+cosmic ray.
+
+And the aborted attempt to look at the inflated output to see what was
+wrong? I could have looked forever and never found it. Here's the diff
+between what the corrupted data inflates to, versus the real data:
+
+--------------
+  -       cp = strtok (arg, "+");
+  +       cp = strtok (arg, ".");
+--------------
+
+It tweaked one byte and still ended up as valid, readable C that just
+happened to do something totally different! One takeaway is that on a
+less unlucky day, looking at the zlib output might have actually been
+helpful, as most random changes would actually break the C code.
+
+But more importantly, git's hashing and checksumming noticed a problem
+that easily could have gone undetected in another system. The result
+still compiled, but would have caused an interesting bug (that would
+have been blamed on some random commit).

+Sometimes you have to rewrite one of a topic branch's commits *and* you can't
+change the topic's branching-off point.  Consider the following situation:
+
+ P---o---o---M---x---x---W---x
+  \         /
+   A---B---C
+
+where commit W reverted commit M because it turned out that commit B was wrong
+and needs to be rewritten, but you need the rewritten topic to still branch
+from commit P (perhaps P is a branching-off point for yet another branch, and
+you want be able to merge the topic into both branches).
+
+The natural thing to do in this case is to checkout the A-B-C branch and use
+"rebase -i P" to change commit B.  However this does not rewrite commit A,
+because "rebase -i" by default fast-forwards over any initial commits selected
+with the "pick" command.  So you end up with this:
+
+ P---o---o---M---x---x---W---x
+  \         /
+   A---B---C   <-- old branch
+    \
+     B'---C'   <-- naively rewritten branch
+
+To merge A-B'-C' into the mainline branch you would still have to first revert
+commit W in order to pick up the changes in A, but then it's likely that the
+changes in B' will conflict with the original B changes re-introduced by the
+reversion of W.
+
+However, you can avoid these problems if you recreate the entire branch,
+including commit A:
+
+   A'---B'---C'  <-- completely rewritten branch
+  /
+ P---o---o---M---x---x---W---x
+  \         /
+   A---B---C
+
+You can merge A'-B'-C' into the mainline branch without worrying about first
+reverting W.  Mainline's history would look like this:
+
+   A'---B'---C'------------------
+  /                              \
+ P---o---o---M---x---x---W---x---M2
+  \         /
+   A---B---C
+
+But if you don't actually need to change commit A, then you need some way to
+recreate it as a new commit with the same changes in it.  The rebase command's
+--no-ff option provides a way to do this:
+
+    $ git rebase [-i] --no-ff P
+
+The --no-ff option creates a new branch A'-B'-C' with all-new commits (all the
+SHA IDs will be different) even if in the interactive case you only actually
+modify commit B.  You can then merge this new branch directly into the mainline
+branch and be sure you'll get all of the branch's changes.
+
+You can also use --no-ff in cases where you just add extra commits to the topic
+to fix it up.  Let's revisit the situation discussed at the start of this howto:
+
+ P---o---o---M---x---x---W---x
+  \         /
+   A---B---C----------------D---E   <-- fixed-up topic branch
+
+At this point, you can use --no-ff to recreate the topic branch:
+
+    $ git checkout E
+    $ git rebase --no-ff P
+
+yielding

+   A'---B'---C'------------D'---E'  <-- recreated topic branch
+  /
+ P---o---o---M---x---x---W---x
+  \         /
+   A---B---C----------------D---E
+
+You can merge the recreated branch into the mainline without reverting commit W,
+and mainline's history will look like this:

+Subject: Using signed tag in pull requests
+Abstract: Beginning v1.7.9, a contributor can push a signed tag to her
+ publishing repository and ask her integrator to pull it. This assures the
+ integrator that the pulled history is authentic and allows others to
+ later validate it.
+Content-type: text/asciidoc
+
+How to use a signed tag in pull requests
+========================================
+
+A typical distributed workflow using Git is for a contributor to fork a
+project, build on it, publish the result to her public repository, and ask
+the "upstream" person (often the owner of the project where she forked
+from) to pull from her public repository. Requesting such a "pull" is made
+easy by the `git request-pull` command.
+
+Earlier, a typical pull request may have started like this:
+
+------------
+ The following changes since commit 406da78032179...:
+
+   Froboz 3.2 (2011-09-30 14:20:57 -0700)
+
+ are available in the Git repository at:
+
+   example.com:/git/froboz.git for-xyzzy
+------------
+
+followed by a shortlog of the changes and a diffstat.
+
+The request was for a branch name (e.g. `for-xyzzy`) in the public
+repository of the contributor, and even though it stated where the
+contributor forked her work from, the message did not say anything about
+the commit to expect at the tip of the for-xyzzy branch. If the site that
+hosts the public repository of the contributor cannot be fully trusted, it
+was unnecessarily hard to make sure what was pulled by the integrator was
+genuinely what the contributor had produced for the project. Also there
+was no easy way for third-party auditors to later verify the resulting
+history.
+
+Starting from Git release v1.7.9, a contributor can add a signed tag to
+the commit at the tip of the history and ask the integrator to pull that
+signed tag. When the integrator runs `git pull`, the signed tag is
+automatically verified to assure that the history is not tampered with.
+In addition, the resulting merge commit records the content of the signed
+tag, so that other people can verify that the branch merged by the
+integrator was signed by the contributor, without fetching the signed tag
+used to validate the pull request separately and keeping it in the refs
+namespace.
+
+This document describes the workflow between the contributor and the
+integrator, using Git v1.7.9 or later.
+
+
+A contributor or a lieutenant
+-----------------------------
+
+After preparing her work to be pulled, the contributor uses `git tag -s`
+to create a signed tag:
+
+------------
+ $ git checkout work
+ $ ... "git pull" from sublieutenants, "git commit" your own work ...
+ $ git tag -s -m "Completed frotz feature" frotz-for-xyzzy work
+------------
+
+Note that this example uses the `-m` option to create a signed tag with
+just a one-liner message, but this is for illustration purposes only. It
+is advisable to compose a well-written explanation of what the topic does
+to justify why it is worthwhile for the integrator to pull it, as this
+message will eventually become part of the final history after the
+integrator responds to the pull request (as we will see later).
+
+Then she pushes the tag out to her public repository:
+
+------------
+ $ git push example.com:/git/froboz.git/ +frotz-for-xyzzy
+------------
+
+There is no need to push the `work` branch or anything else.
+
+Note that the above command line used a plus sign at the beginning of
+`+frotz-for-xyzzy` to allow forcing the update of a tag, as the same
+contributor may want to reuse a signed tag with the same name after the
+previous pull request has already been responded to.
+
+The contributor then prepares a message to request a "pull":
+
+------------
+ $ git request-pull v3.2 example.com:/git/froboz.git/ frotz-for-xyzzy >msg.txt
+------------
+
+The arguments are:
+
+. the version of the integrator's commit the contributor based her work on;
+. the URL of the repository, to which the contributor has pushed what she
+  wants to get pulled; and
+. the name of the tag the contributor wants to get pulled (earlier, she could
+  write only a branch name here).
+
+The resulting msg.txt file begins like so:
+
+------------
+ The following changes since commit 406da78032179...:
+
+   Froboz 3.2 (2011-09-30 14:20:57 -0700)
+
+ are available in the Git repository at:
+
+   example.com:/git/froboz.git tags/frotz-for-xyzzy
+
+ for you to fetch changes up to 703f05ad5835c...:
+
+   Add tests and documentation for frotz (2011-12-02 10:02:52 -0800)
+
+ -----------------------------------------------
+ Completed frotz feature
+ -----------------------------------------------
+------------
+
+followed by a shortlog of the changes and a diffstat.  Comparing this with
+the earlier illustration of the output from the traditional `git request-pull`
+command, the reader should notice that:
+
+. The tip commit to expect is shown to the integrator; and
+. The signed tag message is shown prominently between the dashed lines
+  before the shortlog.
+
+The latter is why the contributor would want to justify why pulling her
+work is worthwhile when creating the signed tag.  The contributor then
+opens her favorite MUA, reads msg.txt, edits and sends it to her upstream
+integrator.
+
+
+Integrator
+----------
+
+After receiving such a pull request message, the integrator fetches and
+integrates the tag named in the request, with:
+
+------------
+ $ git pull example.com:/git/froboz.git/ tags/frotz-for-xyzzy
+------------
+
+This operation will always open an editor to allow the integrator to fine
+tune the commit log message when merging a signed tag.  Also, pulling a
+signed tag will always create a merge commit even when the integrator does
+not have any new commit since the contributor's work forked (i.e. 'fast
+forward'), so that the integrator can properly explain what the merge is
+about and why it was made.
+
+In the editor, the integrator will see something like this:
+
+------------
+ Merge tag 'frotz-for-xyzzy' of example.com:/git/froboz.git/
+
+ Completed frotz feature
+ # gpg: Signature made Fri 02 Dec 2011 10:03:01 AM PST using RSA key ID 96AFE6CB
+ # gpg: Good signature from "Con Tributor <nitfol@example.com>"
+------------
+
+Notice that the message recorded in the signed tag "Completed frotz
+feature" appears here, and again that is why it is important for the
+contributor to explain her work well when creating the signed tag.
+
+As usual, the lines commented with `#` are stripped out. The resulting
+commit records the signed tag used for this validation in a hidden field
+so that it can later be used by others to audit the history. There is no
+need for the integrator to keep a separate copy of the tag in his
+repository (i.e. `git tag -l` won't list the `frotz-for-xyzzy` tag in the
+above example), and there is no need to publish the tag to his public
+repository, either.
+
+After the integrator responds to the pull request and her work becomes
+part of the permanent history, the contributor can remove the tag from
+her public repository, if she chooses, in order to keep the tag namespace
+of her public repository clean, with:
+
+------------
+ $ git push example.com:/git/froboz.git :frotz-for-xyzzy
+------------
+
+
+Auditors
+--------
+
+The `--show-signature` option can be given to `git log` or `git show` and
+shows the verification status of the embedded signed tag in merge commits
+created when the integrator responded to a pull request of a signed tag.
+
+A typical output from `git show --show-signature` may look like this:
+
+------------
+ $ git show --show-signature
+ commit 02306ef6a3498a39118aef9df7975bdb50091585
+ merged tag 'frotz-for-xyzzy'
+ gpg: Signature made Fri 06 Jan 2012 12:41:49 PM PST using RSA key ID 96AFE6CB
+ gpg: Good signature from "Con Tributor <nitfol@example.com>"
+ Merge: 406da78 703f05a

+       Add tests and documentation for frotz
+       ...
+------------
+
+There is no need for the auditor to explicitly fetch the contributor's
+signature, or to even be aware of what tag(s) the contributor and integrator
+used to communicate the signature.  All the required information is recorded
+as part of the merge commit.

+
+NOTE: Some placeholders may depend on other options given to the
+revision traversal engine. For example, the `%g*` reflog options will
+insert an empty string unless we are traversing reflog entries (e.g., by
+`git log -g`). The `%d` and `%D` placeholders will use the "short"
+decoration format if `--decorate` was not already provided on the command
+line.
+
+If you add a `+` (plus sign) after '%' of a placeholder, a line-feed
+is inserted immediately before the expansion if and only if the
+placeholder expands to a non-empty string.
+
+If you add a `-` (minus sign) after '%' of a placeholder, line-feeds that
+immediately precede the expansion are deleted if and only if the
+placeholder expands to an empty string.
+
+If you add a ` ` (space) after '%' of a placeholder, a space
+is inserted immediately before the expansion if and only if the
+placeholder expands to a non-empty string.

-NAME
-----
-gittutorial - Um tutorial de introdução ao git (para versão 1.5.1 ou mais nova)
-
-SYNOPSIS
---------
-git *
-
-DESCRIPTION
------------
-
-Este tutorial explica como importar um novo projeto para o git,
-adicionar mudanças a ele, e compartilhar mudanças com outros
-desenvolvedores.
-
-Se, ao invés disso, você está interessado primariamente em usar git para
-obter um projeto, por exemplo, para testar a última versão, você pode
-preferir começar com os primeiros dois capítulos de
-link:user-manual.html[O Manual do Usuário Git].
-
-Primeiro, note que você pode obter documentação para um comando como
-`git log --graph` com:
-
-------------------------------------------------
-$ man git-log
-------------------------------------------------
-
-ou:
-
-------------------------------------------------
-$ git help log
-------------------------------------------------
-
-Com a última forma, você pode usar o visualizador de manual de sua
-escolha; veja linkgit:git-help[1] para maior informação.
-
-É uma boa idéia informar ao git seu nome e endereço público de email
-antes de fazer qualquer operação. A maneira mais fácil de fazê-lo é:
-
-------------------------------------------------
-$ git config --global user.name "Seu Nome Vem Aqui"
-$ git config --global user.email voce@seudominio.exemplo.com
-------------------------------------------------
-
-
-Importando um novo projeto
------------------------
-
-Assuma que você tem um tarball project.tar.gz com seu trabalho inicial.
-Você pode colocá-lo sob controle de revisão git da seguinte forma:
-
-------------------------------------------------
-$ tar xzf project.tar.gz
-$ cd project
-$ git init
-------------------------------------------------
-
-Git irá responder
-
-------------------------------------------------
-Initialized empty Git repository in .git/
-------------------------------------------------
-
-Você agora iniciou seu diretório de trabalho--você deve ter notado um
-novo diretório criado, com o nome de ".git".
-
-A seguir, diga ao git para gravar um instantâneo do conteúdo de todos os
-arquivos sob o diretório corrente (note o '.'), com 'git-add':
-
-------------------------------------------------
-$ git add .
-------------------------------------------------
-
-Este instantâneo está agora armazenado em uma área temporária que o git
-chama de "index" ou índice. Você pode armazenar permanentemente o
-conteúdo do índice no repositório com 'git-commit':
-
-------------------------------------------------
-$ git commit
-------------------------------------------------
-
-Isto vai te pedir por uma mensagem de commit. Você agora gravou sua
-primeira versão de seu projeto no git.
-
-Fazendo mudanças
---------------
-
-Modifique alguns arquivos, e, então, adicione seu conteúdo atualizado ao
-índice:
-
-------------------------------------------------
-$ git add file1 file2 file3
-------------------------------------------------
-
-Você está agora pronto para fazer o commit. Você pode ver o que está
-para ser gravado usando 'git-diff' com a opção --cached:
-
-------------------------------------------------
-$ git diff --cached
-------------------------------------------------
-
-(Sem --cached, o comando 'git-diff' irá te mostrar quaisquer mudanças
-que você tenha feito mas ainda não adicionou ao índice.) Você também
-pode obter um breve sumário da situação com 'git-status':
-
-------------------------------------------------
-$ git status
-# On branch master
-# Changes to be committed:
-#   (use "git reset HEAD <file>..." to unstage)
-#
-#	modified:   file1
-#	modified:   file2
-#	modified:   file3
-#
-------------------------------------------------
-
-Se você precisar fazer qualquer outro ajuste, faça-o agora, e, então,
-adicione qualquer conteúdo modificado ao índice. Finalmente, grave suas
-mudanças com:
-
-------------------------------------------------
-$ git commit
-------------------------------------------------
-
-Isto irá novamente te pedir por uma mensagem descrevendo a mudança, e,
-então, gravar a nova versão do projeto.
-
-Alternativamente, ao invés de executar 'git-add' antes, você pode usar
-
-------------------------------------------------
-$ git commit -a
-------------------------------------------------
-
-o que irá automaticamente notar quaisquer arquivos modificados (mas não
-novos), adicioná-los ao índices, e gravar, tudo em um único passo.
-
-Uma nota em mensagens de commit: Apesar de não ser exigido, é uma boa
-idéia começar a mensagem com uma simples e curta (menos de 50
-caracteres) linha sumarizando a mudança, seguida de uma linha em branco
-e, então, uma descrição mais detalhada. Ferramentas que transformam
-commits em email, por exemplo, usam a primeira linha no campo de
-cabeçalho Subject: e o resto no corpo.
-
-Git rastreia conteúdo, não arquivos
-----------------------------
-
-Muitos sistemas de controle de revisão provêem um comando `add` que diz
-ao sistema para começar a rastrear mudanças em um novo arquivo. O
-comando `add` do git faz algo mais simples e mais poderoso: 'git-add' é
-usado tanto para arquivos novos e arquivos recentemente modificados, e
-em ambos os casos, ele tira o instantâneo dos arquivos dados e armazena
-o conteúdo no índice, pronto para inclusão do próximo commit.
-
-Visualizando história do projeto
------------------------
-
-Em qualquer ponto você pode visualizar a história das suas mudanças
-usando
-
-------------------------------------------------
-$ git log
-------------------------------------------------
-
-Se você também quer ver a diferença completa a cada passo, use
-
-------------------------------------------------
-$ git log -p
-------------------------------------------------
-
-Geralmente, uma visão geral da mudança é útil para ter a sensação de
-cada passo
-
-------------------------------------------------
-$ git log --stat --summary
-------------------------------------------------
-
-Gerenciando "branches"/ramos
------------------
-
-Um simples repositório git pode manter múltiplos ramos de
-desenvolvimento. Para criar um novo ramo chamado "experimental", use
-
-------------------------------------------------
-$ git branch experimental
-------------------------------------------------
-
-Se você executar agora
-
-------------------------------------------------
-$ git branch
-------------------------------------------------
-
-você vai obter uma lista de todos os ramos existentes:
-
-------------------------------------------------
-  experimental
-* master
-------------------------------------------------
-
-O ramo "experimental" é o que você acaba de criar, e o ramo "master" é o
-ramo padrão que foi criado pra você automaticamente. O asterisco marca
-o ramo em que você está atualmente; digite
-
-------------------------------------------------
-$ git checkout experimental
-------------------------------------------------
-
-para mudar para o ramo experimental. Agora edite um arquivo, grave a
-mudança, e mude de volta para o ramo master:
-
-------------------------------------------------
-(edita arquivo)
-$ git commit -a
-$ git checkout master
-------------------------------------------------
-
-Verifique que a mudança que você fez não está mais visível, já que ela
-foi feita no ramo experimental e você está de volta ao ramo master.
-
-Você pode fazer uma mudança diferente no ramo master:
-
-------------------------------------------------
-(edit file)
-$ git commit -a
-------------------------------------------------
-
-neste ponto, os dois ramos divergiram, com diferentes mudanças feitas em
-cada um. Para unificar as mudanças feitas no experimental para o
-master, execute
-
-------------------------------------------------
-$ git merge experimental
-------------------------------------------------
-
-Se as mudanças não conflitarem, estará pronto. Se existirem conflitos,
-marcadores serão deixados nos arquivos problemáticos exibindo o
-conflito;
-
-------------------------------------------------
-$ git diff
-------------------------------------------------
-
-vai exibir isto. Após você editar os arquivos para resolver os
-conflitos,
-
-------------------------------------------------
-$ git commit -a
-------------------------------------------------
-
-irá gravar o resultado da unificação. Finalmente,
-
-------------------------------------------------
-$ gitk
-------------------------------------------------
-
-vai mostrar uma bela representação gráfica da história resultante.
-
-Neste ponto você pode remover seu ramo experimental com
-
-------------------------------------------------
-$ git branch -d experimental
-------------------------------------------------
-
-Este comando garante que as mudanças no ramo experimental já estão no
-ramo atual.
-
-Se você desenvolve em um ramo ideia-louca, e se arrepende, você pode
-sempre remover o ramo com
-
--------------------------------------
-$ git branch -D ideia-louca
--------------------------------------
-
-Ramos são baratos e fáceis, então isto é uma boa maneira de experimentar
-alguma coisa.
-
-Usando git para colaboração
----------------------------
-
-Suponha que Alice começou um novo projeto com um repositório git em
-/home/alice/project, e que Bob, que tem um diretório home na mesma
-máquina, quer contribuir.
-
-Bob começa com:
-
-------------------------------------------------
-bob$ git clone /home/alice/project myrepo
-------------------------------------------------
-
-Isso cria um novo diretório "myrepo" contendo um clone do repositório de
-Alice. O clone está no mesmo pé que o projeto original, possuindo sua
-própria cópia da história do projeto original.
-
-Bob então faz algumas mudanças e as grava:
-
-------------------------------------------------
-(editar arquivos)
-bob$ git commit -a
-(repetir conforme necessário)
-------------------------------------------------
-
-Quanto está pronto, ele diz a Alice para puxar as mudanças do
-repositório em /home/bob/myrepo. Ela o faz com:
-
-------------------------------------------------
-alice$ cd /home/alice/project
-alice$ git pull /home/bob/myrepo master
-------------------------------------------------
-
-Isto unifica as mudanças do ramo "master" do Bob ao ramo atual de Alice.
-Se Alice fez suas próprias mudanças no intervalo, ela, então, pode
-precisar corrigir manualmente quaisquer conflitos. (Note que o argumento
-"master" no comando acima é, de fato, desnecessário, já que é o padrão.)
-
-O comando "pull" executa, então, duas operações: ele obtém mudanças de
-um ramo remoto, e, então, as unifica no ramo atual.
-
-Note que, em geral, Alice gostaria que suas mudanças locais fossem
-gravadas antes de iniciar este "pull". Se o trabalho de Bob conflita
-com o que Alice fez desde que suas histórias se ramificaram, Alice irá
-usar seu diretório de trabalho e o índice para resolver conflitos, e
-mudanças locais existentes irão interferir com o processo de resolução
-de conflitos (git ainda irá realizar a obtenção mas irá se recusar a
-unificar --- Alice terá que se livrar de suas mudanças locais de alguma
-forma e puxar de novo quando isso acontecer).
-
-Alice pode espiar o que Bob fez sem unificar primeiro, usando o comando
-"fetch"; isto permite Alice inspecionar o que Bob fez, usando um símbolo
-especial "FETCH_HEAD", com o fim de determinar se ele tem alguma coisa
-que vale puxar, assim:
-
-------------------------------------------------
-alice$ git fetch /home/bob/myrepo master
-alice$ git log -p HEAD..FETCH_HEAD
-------------------------------------------------
-
-Esta operação é segura mesmo se Alice tem mudanças locais não gravadas.
-A notação de intervalo "HEAD..FETCH_HEAD" significa mostrar tudo que é
-alcançável de FETCH_HEAD mas exclua tudo o que é alcançável de HEAD.
-Alice já sabe tudo que leva a seu estado atual (HEAD), e revisa o que Bob
-tem em seu estado (FETCH_HEAD) que ela ainda não viu com esse comando.
-
-Se Alice quer visualizar o que Bob fez desde que suas histórias se
-ramificaram, ela pode disparar o seguinte comando:
-
-------------------------------------------------
-$ gitk HEAD..FETCH_HEAD
-------------------------------------------------
-
-Isto usa a mesma notação de intervalo que vimos antes com 'git log'.
-
-Alice pode querer ver o que ambos fizeram desde que ramificaram. Ela
-pode usar a forma com três pontos ao invés da forma com dois pontos:
-
-------------------------------------------------
-$ gitk HEAD...FETCH_HEAD
-------------------------------------------------
-
-Isto significa "mostre tudo que é alcançável de qualquer um deles, mas
-exclua tudo que é alcançável a partir de ambos".
-
-Por favor, note que essas notações de intervalo podem ser usadas tanto
-com gitk quanto com "git log".
-
-Após inspecionar o que Bob fez, se não há nada urgente, Alice pode
-decidir continuar trabalhando sem puxar de Bob. Se a história de Bob
-tem alguma coisa que Alice precisa imediatamente, Alice pode optar por
-separar seu trabalho em progresso primeiro, fazer um "pull", e, então,
-finalmente, retomar seu trabalho em progresso em cima da história
-resultante.
-
-Quando você está trabalhando em um pequeno grupo unido, não é incomum
-interagir com o mesmo repositório várias e várias vezes. Definindo um
-repositório remoto antes de tudo, você pode fazê-lo mais facilmente:
-
-------------------------------------------------
-alice$ git remote add bob /home/bob/myrepo
-------------------------------------------------
-
-Com isso, Alice pode executar a primeira parte da operação "pull" usando
-o comando 'git-fetch' sem unificar suas mudanças com seu próprio ramo,
-usando:
-
--------------------------------------
-alice$ git fetch bob
--------------------------------------
-
-Diferente da forma longa, quando Alice obteve de Bob usando um
-repositório remoto antes definido com 'git-remote', o que foi obtido é
-armazenado em um ramo remoto, neste caso `bob/master`. Então, após isso:
-
--------------------------------------
-alice$ git log -p master..bob/master
--------------------------------------
-
-mostra uma lista de todas as mudanças que Bob fez desde que ramificou do
-ramo master de Alice.
-
-Após examinar essas mudanças, Alice pode unificá-las em seu ramo master:
-
--------------------------------------
-alice$ git merge bob/master
--------------------------------------
-
-Esse `merge` pode também ser feito puxando de seu próprio ramo remoto,
-assim:
-
--------------------------------------
-alice$ git pull . remotes/bob/master
--------------------------------------
-
-Note que 'git pull' sempre unifica ao ramo atual, independente do que
-mais foi passado na linha de comando.
-
-Depois, Bob pode atualizar seu repositório com as últimas mudanças de
-Alice, usando
-
--------------------------------------
-bob$ git pull
--------------------------------------
-
-Note que ele não precisa dar o caminho do repositório de Alice; quando
-Bob clonou seu repositório, o git armazenou a localização de seu
-repositório na configuração do mesmo, e essa localização é usada
-para puxar:
-
--------------------------------------
-bob$ git config --get remote.origin.url
-/home/alice/project
--------------------------------------
-
-(A configuração completa criada por 'git-clone' é visível usando `git
-config -l`, e a página de manual linkgit:git-config[1] explica o
-significado de cada opção.)
-
-Git também mantém uma cópia limpa do ramo master de Alice sob o nome
-"origin/master":
-
--------------------------------------
-bob$ git branch -r
-  origin/master
--------------------------------------
-
-Se Bob decidir depois em trabalhar em um host diferente, ele ainda pode
-executar clones e puxar usando o protocolo ssh:
-
--------------------------------------
-bob$ git clone alice.org:/home/alice/project myrepo
--------------------------------------
-
-Alternativamente, o git tem um protocolo nativo, ou pode usar rsync ou
-http; veja linkgit:git-pull[1] para detalhes.
-
-Git pode também ser usado em um modo parecido com CVS, com um
-repositório central para o qual vários usuários empurram modificações;
-veja linkgit:git-push[1] e linkgit:gitcvs-migration[7].
-
-Explorando história
------------------
-
-A história no git é representada como uma série de commits
-interrelacionados. Nós já vimos que o comando 'git-log' pode listar
-esses commits. Note que a primeira linha de cada entrada no log também
-dá o nome para o commit:
-
--------------------------------------
-$ git log
-commit c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
-Author: Junio C Hamano <junkio@cox.net>
-Date:   Tue May 16 17:18:22 2006 -0700
-
-    merge-base: Clarify the comments on post processing.
--------------------------------------
-
-Nós podemos dar este nome ao 'git-show' para ver os detalhes sobre este
-commit.
-
--------------------------------------
-$ git show c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
--------------------------------------
-
-Mas há outras formas de se referir aos commits. Você pode usar qualquer
-parte inicial do nome que seja longo o bastante para identificar
-unicamente o commit:
-
--------------------------------------
-$ git show c82a22c39c	# os primeiros caracteres do nome são o bastante
-			# usualmente
-$ git show HEAD		# a ponta do ramo atual
-$ git show experimental	# a ponta do ramo "experimental"
--------------------------------------
-
-Todo commit normalmente tem um commit "pai" que aponta para o estado
-anterior do projeto:
-
--------------------------------------
-$ git show HEAD^  # para ver o pai de HEAD
-$ git show HEAD^^ # para ver o avô de HEAD
-$ git show HEAD~4 # para ver o trisavô de HEAD
--------------------------------------
-
-Note que commits de unificação podem ter mais de um pai:
-
--------------------------------------
-$ git show HEAD^1 # mostra o primeiro pai de HEAD (o mesmo que HEAD^)
-$ git show HEAD^2 # mostra o segundo pai de HEAD
--------------------------------------
-
-Você também pode dar aos commits nomes à sua escolha; após executar
-
--------------------------------------
-$ git tag v2.5 1b2e1d63ff
--------------------------------------
-
-você pode se referir a 1b2e1d63ff pelo nome "v2.5". Se você pretende
-compartilhar esse nome com outras pessoas (por exemplo, para identificar
-uma versão de lançamento), você deveria criar um objeto "tag", e talvez
-assiná-lo; veja linkgit:git-tag[1] para detalhes.
-
-Qualquer comando git que precise conhecer um commit pode receber
-quaisquer desses nomes. Por exemplo:
-
--------------------------------------
-$ git diff v2.5 HEAD	 # compara o HEAD atual com v2.5
-$ git branch stable v2.5 # inicia um novo ramo chamado "stable" baseado
-			 # em v2.5
-$ git reset --hard HEAD^ # reseta seu ramo atual e seu diretório de
-			 # trabalho a seu estado em HEAD^
--------------------------------------
-
-Seja cuidadoso com o último comando: além de perder quaisquer mudanças
-em seu diretório de trabalho, ele também remove todos os commits
-posteriores desse ramo. Se esse ramo é o único ramo contendo esses
-commits, eles serão perdidos. Também, não use 'git-reset' num ramo
-publicamente visível de onde outros desenvolvedores puxam, já que vai
-forçar unificações desnecessárias para que outros desenvolvedores limpem
-a história. Se você precisa desfazer mudanças que você empurrou, use
-'git-revert' no lugar.
-
-O comando 'git-grep' pode buscar strings em qualquer versão de seu
-projeto, então
-
--------------------------------------
-$ git grep "hello" v2.5
--------------------------------------
-
-procura por todas as ocorrências de "hello" em v2.5.
-
-Se você deixar de fora o nome do commit, 'git-grep' irá procurar
-quaisquer dos arquivos que ele gerencia no diretório corrente. Então
-
--------------------------------------
-$ git grep "hello"
--------------------------------------
-
-é uma forma rápida de buscar somente os arquivos que são rastreados pelo
-git.
-
-Muitos comandos git também recebem um conjunto de commits, o que pode
-ser especificado de várias formas. Aqui estão alguns exemplos com 'git-log':
-
--------------------------------------
-$ git log v2.5..v2.6            # commits entre v2.5 e v2.6
-$ git log v2.5..                # commits desde v2.5
-$ git log --since="2 weeks ago" # commits das últimas 2 semanas
-$ git log v2.5.. Makefile       # commits desde v2.5 que modificam
-				# Makefile
--------------------------------------
-
-Você também pode dar ao 'git-log' um "intervalo" de commits onde o
-primeiro não é necessariamente um ancestral do segundo; por exemplo, se
-as pontas dos ramos "stable" e "master" divergiram de um commit
-comum algum tempo atrás, então
-
--------------------------------------
-$ git log stable..master
--------------------------------------
-
-irá listar os commits feitos no ramo "master" mas não no ramo
-"stable", enquanto
-
--------------------------------------
-$ git log master..stable
--------------------------------------
-
-irá listar a lista de commits feitos no ramo "stable" mas não no ramo
-"master".
-
-O comando 'git-log' tem uma fraqueza: ele precisa mostrar os commits em
-uma lista. Quando a história tem linhas de desenvolvimento que
-divergiram e então foram unificadas novamente, a ordem em que 'git-log'
-apresenta essas mudanças é irrelevante.
-
-A maioria dos projetos com múltiplos contribuidores (como o kernel
-Linux, ou o próprio git) tem unificações frequentes, e 'gitk' faz um
-trabalho melhor de visualizar sua história. Por exemplo,
-
--------------------------------------
-$ gitk --since="2 weeks ago" drivers/
--------------------------------------

-Este tutorial deve ser o bastante para operar controle de revisão
-distribuído básico para seus projetos. No entanto, para entender
-plenamente a profundidade e o poder do git você precisa entender duas
-idéias simples nas quais ele se baseia:
-
-  * A base de objetos é um sistema bem elegante usado para armazenar a
-    história de seu projeto--arquivos, diretórios, e commits.
-
-  * O arquivo de índice é um cache do estado de uma árvore de diretório,
-    usado para criar commits, restaurar diretórios de trabalho, e
-    armazenar as várias árvores envolvidas em uma unificação.
-
-A parte dois deste tutorial explica a base de objetos, o arquivo de
-índice, e algumas outras coisinhas que você vai precisar pra usar o
-máximo do git. Você pode encontrá-la em linkgit:gittutorial-2[7].
-
-Se você não quiser continuar com o tutorial agora nesse momento, algumas
-outras digressões que podem ser interessantes neste ponto são:
-
-  * linkgit:git-format-patch[1], linkgit:git-am[1]: Estes convertem
-    séries de commits em patches para email, e vice-versa, úteis para
-    projetos como o kernel Linux que dependem fortemente de patches
-    enviados por email.
-
-  * linkgit:git-bisect[1]: Quando há uma regressão em seu projeto, uma
-    forma de rastrear um bug é procurando pela história para encontrar o
-    commit culpado. Git bisect pode ajudar a executar uma busca binária
-    por esse commit. Ele é inteligente o bastante para executar uma
-    busca próxima da ótima mesmo no caso de uma história complexa
-    não-linear com muitos ramos unificados.

+SPECIFYING REVISIONS
+--------------------
+
+A revision parameter '<rev>' typically, but not necessarily, names a
+commit object.  It uses what is called an 'extended SHA-1'
+syntax.  Here are various ways to spell object names.  The
+ones listed near the end of this list name trees and
+blobs contained in a commit.
+
+'<sha1>', e.g. 'dae86e1950b1277e545cee180551750029cfe735', 'dae86e'::
+  The full SHA-1 object name (40-byte hexadecimal string), or
+  a leading substring that is unique within the repository.
+  E.g. dae86e1950b1277e545cee180551750029cfe735 and dae86e both
+  name the same commit object if there is no other object in
+  your repository whose object name starts with dae86e.
+
+'<describeOutput>', e.g. 'v1.7.4.2-679-g3bee7fb'::
+  Output from `git describe`; i.e. a closest tag, optionally
+  followed by a dash and a number of commits, followed by a dash, a
+  'g', and an abbreviated object name.
+
+'<refname>', e.g. 'master', 'heads/master', 'refs/heads/master'::
+  A symbolic ref name.  E.g. 'master' typically means the commit
+  object referenced by 'refs/heads/master'.  If you
+  happen to have both 'heads/master' and 'tags/master', you can
+  explicitly say 'heads/master' to tell Git which one you mean.
+  When ambiguous, a '<refname>' is disambiguated by taking the
+  first match in the following rules:
+
+  . If '$GIT_DIR/<refname>' exists, that is what you mean (this is usually
+    useful only for 'HEAD', 'FETCH_HEAD', 'ORIG_HEAD', 'MERGE_HEAD'
+    and 'CHERRY_PICK_HEAD');

+
+  . otherwise, 'refs/remotes/<refname>' if it exists;
+
+  . otherwise, 'refs/remotes/<refname>/HEAD' if it exists.
++
+'HEAD' names the commit on which you based the changes in the working tree.
+'FETCH_HEAD' records the branch which you fetched from a remote repository
+with your last `git fetch` invocation.
+'ORIG_HEAD' is created by commands that move your 'HEAD' in a drastic

+them.
+'MERGE_HEAD' records the commit(s) which you are merging into your branch

+'CHERRY_PICK_HEAD' records the commit which you are cherry-picking

++
+Note that any of the 'refs/*' cases above may come either from

+
+'@'::
+  '@' alone is a shortcut for 'HEAD'.
+
+'<refname>@\{<date>\}', e.g. 'master@\{yesterday\}', 'HEAD@\{5 minutes ago\}'::
+  A ref followed by the suffix '@' with a date specification
+  enclosed in a brace
+  pair (e.g. '\{yesterday\}', '\{1 month 2 weeks 3 days 1 hour 1
+  second ago\}' or '\{1979-02-26 18:30:00\}') specifies the value
+  of the ref at a prior point in time.  This suffix may only be
+  used immediately following a ref name and the ref must have an
+  existing log ('$GIT_DIR/logs/<ref>'). Note that this looks up the state
+  of your *local* ref at a given time; e.g., what was in your local
+  'master' branch last week. If you want to look at commits made during
+  certain times, see '--since' and '--until'.
+
+'<refname>@\{<n>\}', e.g. 'master@\{1\}'::
+  A ref followed by the suffix '@' with an ordinal specification
+  enclosed in a brace pair (e.g. '\{1\}', '\{15\}') specifies
+  the n-th prior value of that ref.  For example 'master@\{1\}'
+  is the immediate prior value of 'master' while 'master@\{5\}'
+  is the 5th prior value of 'master'. This suffix may only be used
+  immediately following a ref name and the ref must have an existing
+  log ('$GIT_DIR/logs/<refname>').
+
+'@\{<n>\}', e.g. '@\{1\}'::
+  You can use the '@' construct with an empty ref part to get at a
+  reflog entry of the current branch. For example, if you are on
+  branch 'blabla' then '@\{1\}' means the same as 'blabla@\{1\}'.
+
+'@\{-<n>\}', e.g. '@\{-1\}'::
+  The construct '@\{-<n>\}' means the <n>th branch/commit checked out
+  before the current one.
+
+'<branchname>@\{upstream\}', e.g. 'master@\{upstream\}', '@\{u\}'::
+  The suffix '@\{upstream\}' to a branchname (short form '<branchname>@\{u\}')
+  refers to the branch that the branch specified by branchname is set to build on
+  top of (configured with `branch.<name>.remote` and
+  `branch.<name>.merge`).  A missing branchname defaults to the
+  current one.
+
+'<rev>{caret}', e.g. 'HEAD{caret}, v1.5.1{caret}0'::
+  A suffix '{caret}' to a revision parameter means the first parent of
+  that commit object.  '{caret}<n>' means the <n>th parent (i.e.
+  '<rev>{caret}'
+  is equivalent to '<rev>{caret}1').  As a special rule,
+  '<rev>{caret}0' means the commit itself and is used when '<rev>' is the
+  object name of a tag object that refers to a commit object.
+
+'<rev>{tilde}<n>', e.g. 'master{tilde}3'::
+  A suffix '{tilde}<n>' to a revision parameter means the commit
+  object that is the <n>th generation ancestor of the named
+  commit object, following only the first parents.  I.e. '<rev>{tilde}3' is
+  equivalent to '<rev>{caret}{caret}{caret}' which is equivalent to
+  '<rev>{caret}1{caret}1{caret}1'.  See below for an illustration of
+  the usage of this form.
+
+'<rev>{caret}\{<type>\}', e.g. 'v0.99.8{caret}\{commit\}'::
+  A suffix '{caret}' followed by an object type name enclosed in
+  brace pair means dereference the object at '<rev>' recursively until
+  an object of type '<type>' is found or the object cannot be
+  dereferenced anymore (in which case, barf).
+  For example, if '<rev>' is a commit-ish, '<rev>{caret}\{commit\}'
+  describes the corresponding commit object.
+  Similarly, if '<rev>' is a tree-ish, '<rev>{caret}\{tree\}'
+  describes the corresponding tree object.
+  '<rev>{caret}0'
+  is a short-hand for '<rev>{caret}\{commit\}'.
++
+'rev{caret}\{object\}' can be used to make sure 'rev' names an
+object that exists, without requiring 'rev' to be a tag, and
+without dereferencing 'rev'; because a tag is already an object,
+it does not have to be dereferenced even once to get to an object.
++
+'rev{caret}\{tag\}' can be used to ensure that 'rev' identifies an
+existing tag object.
+
+'<rev>{caret}\{\}', e.g. 'v0.99.8{caret}\{\}'::
+  A suffix '{caret}' followed by an empty brace pair
+  means the object could be a tag,
+  and dereference the tag recursively until a non-tag object is
+  found.
+
+'<rev>{caret}\{/<text>\}', e.g. 'HEAD^{/fix nasty bug}'::
+  A suffix '{caret}' to a revision parameter, followed by a brace
+  pair that contains a text led by a slash,
+  is the same as the ':/fix nasty bug' syntax below except that
+  it returns the youngest matching commit which is reachable from
+  the '<rev>' before '{caret}'.
+
+':/<text>', e.g. ':/fix nasty bug'::
+  A colon, followed by a slash, followed by a text, names
+  a commit whose commit message matches the specified regular expression.
+  This name returns the youngest matching commit which is
+  reachable from any ref.  If the commit message starts with a
+  '!' you have to repeat that;  the special sequence ':/!',
+  followed by something else than '!', is reserved for now.
+  The regular expression can match any part of the commit message. To
+  match messages starting with a string, one can use e.g. ':/^foo'.
+
+'<rev>:<path>', e.g. 'HEAD:README', ':README', 'master:./README'::
+  A suffix ':' followed by a path names the blob or tree
+  at the given path in the tree-ish object named by the part
+  before the colon.
+  ':path' (with an empty part before the colon)
+  is a special case of the syntax described next: content
+  recorded in the index at the given path.
+  A path starting with './' or '../' is relative to the current working directory.
+  The given path will be converted to be relative to the working tree's root directory.
+  This is most useful to address a blob or tree from a commit or tree that has
+  the same tree structure as the working tree.
+
+':<n>:<path>', e.g. ':0:README', ':README'::
+  A colon, optionally followed by a stage number (0 to 3) and a
+  colon, followed by a path, names a blob object in the
+  index at the given path. A missing stage number (and the colon
+  that follows it) names a stage 0 entry. During a merge, stage
+  1 is the common ancestor, stage 2 is the target branch's version
+  (typically the current branch), and stage 3 is the version from
+  the branch which is being merged.
+
+Here is an illustration, by Jon Loeliger.  Both commit nodes B
+and C are parents of commit node A.  Parent commits are ordered
+left-to-right.
+

+G   H   I   J

+
+
+SPECIFYING RANGES
+-----------------
+
+History traversing commands such as `git log` operate on a set
+of commits, not just a single commit.  To these commands,
+specifying a single revision with the notation described in the
+previous section means the set of commits reachable from that
+commit, following the commit ancestry chain.
+
+To exclude commits reachable from a commit, a prefix '{caret}'
+notation is used.  E.g. '{caret}r1 r2' means commits reachable
+from 'r2' but exclude the ones reachable from 'r1'.
+
+This set operation appears so often that there is a shorthand
+for it.  When you have two commits 'r1' and 'r2' (named according
+to the syntax explained in SPECIFYING REVISIONS above), you can ask
+for commits that are reachable from r2 excluding those that are reachable
+from r1 by '{caret}r1 r2' and it can be written as 'r1..r2'.
+
+A similar notation 'r1\...r2' is called symmetric difference
+of 'r1' and 'r2' and is defined as
+'r1 r2 --not $(git merge-base --all r1 r2)'.
+It is the set of commits that are reachable from either one of
+'r1' or 'r2' but not from both.
+
+In these two shorthands, you can omit one end and let it default to HEAD.
+For example, 'origin..' is a shorthand for 'origin..HEAD' and asks "What
+did I do since I forked from the origin branch?"  Similarly, '..origin'
+is a shorthand for 'HEAD..origin' and asks "What did the origin do since
+I forked from them?"  Note that '..' would mean 'HEAD..HEAD' which is an
+empty range that is both reachable and unreachable from HEAD.
+
+Two other shorthands for naming a set that is formed by a commit
+and its parent commits exist.  The 'r1{caret}@' notation means all
+parents of 'r1'.  'r1{caret}!' includes commit 'r1' but excludes
+all of its parents.
+
+To summarize:
+
+'<rev>'::
+	Include commits that are reachable from (i.e. ancestors of)
+	<rev>.
+
+'{caret}<rev>'::
+	Exclude commits that are reachable from (i.e. ancestors of)
+	<rev>.
+
+'<rev1>..<rev2>'::
+	Include commits that are reachable from <rev2> but exclude
+	those that are reachable from <rev1>.  When either <rev1> or
+	<rev2> is omitted, it defaults to 'HEAD'.
+
+'<rev1>\...<rev2>'::
+	Include commits that are reachable from either <rev1> or
+	<rev2> but exclude those that are reachable from both.  When
+	either <rev1> or <rev2> is omitted, it defaults to 'HEAD'.
+
+'<rev>{caret}@', e.g. 'HEAD{caret}@'::
+  A suffix '{caret}' followed by an at sign is the same as listing
+  all parents of '<rev>' (meaning, include anything reachable from
+  its parents, but not the commit itself).
+
+'<rev>{caret}!', e.g. 'HEAD{caret}!'::
+  A suffix '{caret}' followed by an exclamation mark is the same
+  as giving commit '<rev>' and then all its parents prefixed with
+  '{caret}' to exclude them (and their ancestors).
+
+Here are a handful of examples:
+
+   D                G H D
+   D F              G H I J D F
+   ^G D             H D
+   ^D B             E I J F B
+   B..C             C
+   B...C            G H D E B C
+   ^D B C           E I J F B C
+   C                I J F C
+   C^@              I J F

+argv-array API
+==============
+
+The argv-array API allows one to dynamically build and store
+NULL-terminated lists.  An argv-array maintains the invariant that the
+`argv` member always points to a non-NULL array, and that the array is
+always NULL-terminated at the element pointed to by `argv[argc]`. This
+makes the result suitable for passing to functions expecting to receive
+argv from main(), or the link:api-run-command.html[run-command API].
+
+The link:api-string-list.html[string-list API] is similar, but cannot be
+used for these purposes; instead of storing a straight string pointer,
+it contains an item structure with a `util` field that is not compatible
+with the traditional argv interface.
+
+Each `argv_array` manages its own memory. Any strings pushed into the
+array are duplicated, and all memory is freed by argv_array_clear().
+
+Data Structures
+---------------
+
+`struct argv_array`::
+
+	A single array. This should be initialized by assignment from
+	`ARGV_ARRAY_INIT`, or by calling `argv_array_init`. The `argv`

+	NULL.

+config API
+==========
+
+The config API gives callers a way to access Git configuration files
+(and files which have the same syntax). See linkgit:git-config[1] for a
+discussion of the config file syntax.
+
+General Usage
+-------------
+
+Config files are parsed linearly, and each variable found is passed to a
+caller-provided callback function. The callback function is responsible
+for any actions to be taken on the config option, and is free to ignore
+some options. It is not uncommon for the configuration to be parsed
+several times during the run of a Git program, with different callbacks
+picking out different variables useful to themselves.
+
+A config callback function takes three parameters:
+
+- the name of the parsed variable. This is in canonical "flat" form: the
+  section, subsection, and variable segments will be separated by dots,
+  and the section and variable segments will be all lowercase. E.g.,
+  `core.ignorecase`, `diff.SomeType.textconv`.
+
+- the value of the found variable, as a string. If the variable had no
+  value specified, the value will be NULL (typically this means it
+  should be interpreted as boolean true).
+
+- a void pointer passed in by the caller of the config API; this can
+  contain callback-specific data
+
+A config callback should return 0 for success, or -1 if the variable
+could not be parsed properly.
+
+Basic Config Querying
+---------------------
+
+Most programs will simply want to look up variables in all config files
+that Git knows about, using the normal precedence rules. To do this,
+call `git_config` with a callback function and void data pointer.
+
+`git_config` will read all config sources in order of increasing
+priority. Thus a callback should typically overwrite previously-seen
+entries with new ones (e.g., if both the user-wide `~/.gitconfig` and
+repo-specific `.git/config` contain `color.ui`, the config machinery
+will first feed the user-wide one to the callback, and then the
+repo-specific one; by overwriting, the higher-priority repo-specific
+value is left at the end).
+
+The `git_config_with_options` function lets the caller examine config
+while adjusting some of the default behavior of `git_config`. It should
+almost never be used by "regular" Git code that is looking up
+configuration variables. It is intended for advanced callers like
+`git-config`, which are intentionally tweaking the normal config-lookup
+process. It takes two extra parameters:
+
+`filename`::
+If this parameter is non-NULL, it specifies the name of a file to
+parse for configuration, rather than looking in the usual files. Regular
+`git_config` defaults to `NULL`.
+
+`respect_includes`::
+Specify whether include directives should be followed in parsed files.
+Regular `git_config` defaults to `1`.
+
+There is a special version of `git_config` called `git_config_early`.
+This version takes an additional parameter to specify the repository
+config, instead of having it looked up via `git_path`. This is useful
+early in a Git program before the repository has been found. Unless
+you're working with early setup code, you probably don't want to use
+this.
+
+Reading Specific Files
+----------------------
+
+To read a specific file in git-config format, use
+`git_config_from_file`. This takes the same callback and data parameters
+as `git_config`.
+
+Querying For Specific Variables
+-------------------------------
+
+For programs wanting to query for specific variables in a non-callback
+manner, the config API provides two functions `git_config_get_value`
+and `git_config_get_value_multi`. They both read values from an internal
+cache generated previously from reading the config files.
+
+`int git_config_get_value(const char *key, const char **value)`::
+
+	Finds the highest-priority value for the configuration variable `key`,
+	stores the pointer to it in `value` and returns 0. When the
+	configuration variable `key` is not found, returns 1 without touching
+	`value`. The caller should not free or modify `value`, as it is owned
+	by the cache.
+
+`const struct string_list *git_config_get_value_multi(const char *key)`::
+
+	Finds and returns the value list, sorted in order of increasing priority
+	for the configuration variable `key`. When the configuration variable
+	`key` is not found, returns NULL. The caller should not free or modify
+	the returned pointer, as it is owned by the cache.
+
+`void git_config_clear(void)`::
+
+	Resets and invalidates the config cache.
+
+The config API also provides type specific API functions which do conversion
+as well as retrieval for the queried variable, including:
+
+`int git_config_get_int(const char *key, int *dest)`::
+
+	Finds and parses the value to an integer for the configuration variable
+	`key`. Dies on error; otherwise, stores the value of the parsed integer in
+	`dest` and returns 0. When the configuration variable `key` is not found,
+	returns 1 without touching `dest`.
+
+`int git_config_get_ulong(const char *key, unsigned long *dest)`::
+
+	Similar to `git_config_get_int` but for unsigned longs.
+
+`int git_config_get_bool(const char *key, int *dest)`::
+
+	Finds and parses the value into a boolean value, for the configuration
+	variable `key` respecting keywords like "true" and "false". Integer
+	values are converted into true/false values (when they are non-zero or
+	zero, respectively). Other values cause a die(). If parsing is successful,
+	stores the value of the parsed result in `dest` and returns 0. When the
+	configuration variable `key` is not found, returns 1 without touching
+	`dest`.
+
+`int git_config_get_bool_or_int(const char *key, int *is_bool, int *dest)`::
+
+	Similar to `git_config_get_bool`, except that integers are copied as-is,
+	and `is_bool` flag is unset.
+
+`int git_config_get_maybe_bool(const char *key, int *dest)`::
+
+	Similar to `git_config_get_bool`, except that it returns -1 on error
+	rather than dying.
+
+`int git_config_get_string_const(const char *key, const char **dest)`::
+
+	Allocates and copies the retrieved string into the `dest` parameter for
+	the configuration variable `key`; if NULL string is given, prints an
+	error message and returns -1. When the configuration variable `key` is
+	not found, returns 1 without touching `dest`.
+
+`int git_config_get_string(const char *key, char **dest)`::
+
+	Similar to `git_config_get_string_const`, except that retrieved value
+	copied into the `dest` parameter is a mutable string.
+
+`int git_config_get_pathname(const char *key, const char **dest)`::
+
+	Similar to `git_config_get_string`, but expands `~` or `~user` into
+	the user's home directory when found at the beginning of the path.
+
+`git_die_config(const char *key, const char *err, ...)`::
+
+	First prints the error message specified by the caller in `err` and then
+	dies printing the line number and the file name of the highest priority
+	value for the configuration variable `key`.
+
+`void git_die_config_linenr(const char *key, const char *filename, int linenr)`::
+
+	Helper function which formats the die error message according to the
+	parameters entered. Used by `git_die_config()`. It can be used by callers
+	handling `git_config_get_value_multi()` to print the correct error message
+	for the desired value.
+
+See test-config.c for usage examples.
+
+Value Parsing Helpers
+---------------------
+
+To aid in parsing string values, the config API provides callbacks with
+a number of helper functions, including:
+
+`git_config_int`::
+Parse the string to an integer, including unit factors. Dies on error;
+otherwise, returns the parsed result.
+
+`git_config_ulong`::
+Identical to `git_config_int`, but for unsigned longs.
+
+`git_config_bool`::
+Parse a string into a boolean value, respecting keywords like "true" and
+"false". Integer values are converted into true/false values (when they
+are non-zero or zero, respectively). Other values cause a die(). If
+parsing is successful, the return value is the result.
+
+`git_config_bool_or_int`::
+Same as `git_config_bool`, except that integers are returned as-is, and
+an `is_bool` flag is unset.
+
+`git_config_maybe_bool`::
+Same as `git_config_bool`, except that it returns -1 on error rather
+than dying.
+
+`git_config_string`::
+Allocates and copies the value string into the `dest` parameter; if no
+string is given, prints an error message and returns -1.
+
+`git_config_pathname`::
+Similar to `git_config_string`, but expands `~` or `~user` into the
+user's home directory when found at the beginning of the path.
+
+Include Directives
+------------------
+
+By default, the config parser does not respect include directives.
+However, a caller can use the special `git_config_include` wrapper
+callback to support them. To do so, you simply wrap your "real" callback
+function and data pointer in a `struct config_include_data`, and pass
+the wrapper to the regular config-reading functions. For example:
+
+-------------------------------------------
+int read_file_with_include(const char *file, config_fn_t fn, void *data)
+{
+	struct config_include_data inc = CONFIG_INCLUDE_INIT;
+	inc.fn = fn;
+	inc.data = data;
+	return git_config_from_file(git_config_include, file, &inc);
+}
+-------------------------------------------
+
+`git_config` respects includes automatically. The lower-level
+`git_config_from_file` does not.
+
+Custom Configsets
+-----------------
+
+A `config_set` can be used to construct an in-memory cache for
+config-like files that the caller specifies (i.e., files like `.gitmodules`,
+`~/.gitconfig` etc.). For example,
+
+---------------------------------------
+struct config_set gm_config;
+git_configset_init(&gm_config);
+int b;
+/* we add config files to the config_set */
+git_configset_add_file(&gm_config, ".gitmodules");
+git_configset_add_file(&gm_config, ".gitmodules_alt");
+
+if (!git_configset_get_bool(gm_config, "submodule.frotz.ignore", &b)) {
+	/* hack hack hack */
+}
+
+/* when we are done with the configset */
+git_configset_clear(&gm_config);
+----------------------------------------
+
+Configset API provides functions for the above mentioned work flow, including:
+
+`void git_configset_init(struct config_set *cs)`::
+
+	Initializes the config_set `cs`.
+
+`int git_configset_add_file(struct config_set *cs, const char *filename)`::
+
+	Parses the file and adds the variable-value pairs to the `config_set`,
+	dies if there is an error in parsing the file. Returns 0 on success, or
+	-1 if the file does not exist or is inaccessible. The user has to decide
+	if he wants to free the incomplete configset or continue using it when
+	the function returns -1.
+
+`int git_configset_get_value(struct config_set *cs, const char *key, const char **value)`::
+
+	Finds the highest-priority value for the configuration variable `key`
+	and config set `cs`, stores the pointer to it in `value` and returns 0.
+	When the configuration variable `key` is not found, returns 1 without
+	touching `value`. The caller should not free or modify `value`, as it
+	is owned by the cache.
+
+`const struct string_list *git_configset_get_value_multi(struct config_set *cs, const char *key)`::
+
+	Finds and returns the value list, sorted in order of increasing priority
+	for the configuration variable `key` and config set `cs`. When the
+	configuration variable `key` is not found, returns NULL. The caller
+	should not free or modify the returned pointer, as it is owned by the cache.
+
+`void git_configset_clear(struct config_set *cs)`::
+
+	Clears `config_set` structure, removes all saved variable-value pairs.
+
+In addition to above functions, the `config_set` API provides type specific
+functions in the vein of `git_config_get_int` and family but with an extra
+parameter, pointer to struct `config_set`.
+They all behave similarly to the `git_config_get*()` family described in
+"Querying For Specific Variables" above.
+
+Writing Config Files
+--------------------
+
+Git gives multiple entry points in the Config API to write config values to
+files namely `git_config_set_in_file` and `git_config_set`, which write to
+a specific config file or to `.git/config` respectively. They both take a
+key/value pair as parameter.
+In the end they both call `git_config_set_multivar_in_file` which takes four
+parameters:
+
+- the name of the file, as a string, to which key/value pairs will be written.
+
+- the name of key, as a string. This is in canonical "flat" form: the section,
+  subsection, and variable segments will be separated by dots, and the section
+  and variable segments will be all lowercase.
+  E.g., `core.ignorecase`, `diff.SomeType.textconv`.
+
+- the value of the variable, as a string. If value is equal to NULL, it will
+  remove the matching key from the config file.
+
+- the value regex, as a string. It will disregard key/value pairs where value
+  does not match.
+
+- a multi_replace value, as an int. If value is equal to zero, nothing or only
+  one matching key/value is replaced, else all matching key/values (regardless
+  how many) are removed, before the new pair is written.
+
+It returns 0 on success.
+
+Also, there are functions `git_config_rename_section` and
+`git_config_rename_section_in_file` with parameters `old_name` and `new_name`
+for renaming or removing sections in the config files. If NULL is passed
+through `new_name` parameter, the section will be removed from the config file.

+credentials API
+===============
+
+The credentials API provides an abstracted way of gathering username and
+password credentials from the user (even though credentials in the wider
+world can take many forms, in this document the word "credential" always
+refers to a username and password pair).
+
+This document describes two interfaces: the C API that the credential
+subsystem provides to the rest of Git, and the protocol that Git uses to
+communicate with system-specific "credential helpers". If you are
+writing Git code that wants to look up or prompt for credentials, see
+the section "C API" below. If you want to write your own helper, see
+the section on "Credential Helpers" below.
+
+Typical setup
+-------------
+
+------------
++-----------------------+
+| Git code (C)          |--- to server requiring --->
+|                       |        authentication
+|.......................|
+| C credential API      |--- prompt ---> User
++-----------------------+
+	^      |
+	| pipe |
+	|      v
++-----------------------+
+| Git credential helper |
++-----------------------+
+------------
+
+The Git code (typically a remote-helper) will call the C API to obtain
+credential data like a login/password pair (credential_fill). The
+API will itself call a remote helper (e.g. "git credential-cache" or
+"git credential-store") that may retrieve credential data from a
+store. If the credential helper cannot find the information, the C API
+will prompt the user. Then, the caller of the API takes care of
+contacting the server, and does the actual authentication.
+
+C API
+-----
+
+The credential C API is meant to be called by Git code which needs to
+acquire or store a credential. It is centered around an object
+representing a single credential and provides three basic operations:
+fill (acquire credentials by calling helpers and/or prompting the user),
+approve (mark a credential as successfully used so that it can be stored
+for later use), and reject (mark a credential as unsuccessful so that it
+can be erased from any persistent storage).
+
+Data Structures
+~~~~~~~~~~~~~~~
+
+`struct credential`::
+
+	This struct represents a single username/password combination
+	along with any associated context. All string fields should be
+	heap-allocated (or NULL if they are not known or not applicable).
+	The meaning of the individual context fields is the same as
+	their counterparts in the helper protocol; see the section below
+	for a description of each field.
++
+The `helpers` member of the struct is a `string_list` of helpers.  Each
+string specifies an external helper which will be run, in order, to
+either acquire or store credentials. See the section on credential
+helpers below. This list is filled-in by the API functions
+according to the corresponding configuration variables before
+consulting helpers, so there usually is no need for a caller to
+modify the helpers field at all.
++
+This struct should always be initialized with `CREDENTIAL_INIT` or
+`credential_init`.
+
+
+Functions
+~~~~~~~~~
+
+`credential_init`::
+
+	Initialize a credential structure, setting all fields to empty.
+
+`credential_clear`::
+
+	Free any resources associated with the credential structure,
+	returning it to a pristine initialized state.
+
+`credential_fill`::
+
+	Instruct the credential subsystem to fill the username and
+	password fields of the passed credential struct by first
+	consulting helpers, then asking the user. After this function
+	returns, the username and password fields of the credential are
+	guaranteed to be non-NULL. If an error occurs, the function will
+	die().
+
+`credential_reject`::
+
+	Inform the credential subsystem that the provided credentials
+	have been rejected. This will cause the credential subsystem to
+	notify any helpers of the rejection (which allows them, for
+	example, to purge the invalid credentials from storage).  It
+	will also free() the username and password fields of the
+	credential and set them to NULL (readying the credential for
+	another call to `credential_fill`). Any errors from helpers are
+	ignored.
+
+`credential_approve`::
+
+	Inform the credential subsystem that the provided credentials
+	were successfully used for authentication.  This will cause the
+	credential subsystem to notify any helpers of the approval, so
+	that they may store the result to be used again.  Any errors
+	from helpers are ignored.
+
+`credential_from_url`::
+
+	Parse a URL into broken-down credential fields.
+
+Example
+~~~~~~~
+
+The example below shows how the functions of the credential API could be
+used to login to a fictitious "foo" service on a remote host:
+
+-----------------------------------------------------------------------
+int foo_login(struct foo_connection *f)
+{
+	int status;
+	/*
+	 * Create a credential with some context; we don't yet know the
+	 * username or password.
+	 */
+
+	struct credential c = CREDENTIAL_INIT;
+	c.protocol = xstrdup("foo");
+	c.host = xstrdup(f->hostname);
+
+	/*
+	 * Fill in the username and password fields by contacting
+	 * helpers and/or asking the user. The function will die if it
+	 * fails.
+	 */
+	credential_fill(&c);
+
+	/*
+	 * Otherwise, we have a username and password. Try to use it.
+	 */
+	status = send_foo_login(f, c.username, c.password);
+	switch (status) {
+	case FOO_OK:
+		/* It worked. Store the credential for later use. */
+		credential_accept(&c);
+		break;
+	case FOO_BAD_LOGIN:
+		/* Erase the credential from storage so we don't try it
+		 * again. */
+		credential_reject(&c);
+		break;
+	default:
+		/*
+		 * Some other error occurred. We don't know if the
+		 * credential is good or bad, so report nothing to the
+		 * credential subsystem.
+		 */
+	}
+
+	/* Free any associated resources. */
+	credential_clear(&c);
+
+	return status;
+}
+-----------------------------------------------------------------------
+
+
+Credential Helpers
+------------------
+
+Credential helpers are programs executed by Git to fetch or save
+credentials from and to long-term storage (where "long-term" is simply
+longer than a single Git process; e.g., credentials may be stored
+in-memory for a few minutes, or indefinitely on disk).
+
+Each helper is specified by a single string in the configuration
+variable `credential.helper` (and others, see linkgit:git-config[1]).
+The string is transformed by Git into a command to be executed using
+these rules:
+
+  1. If the helper string begins with "!", it is considered a shell
+     snippet, and everything after the "!" becomes the command.
+
+  2. Otherwise, if the helper string begins with an absolute path, the
+     verbatim helper string becomes the command.
+
+  3. Otherwise, the string "git credential-" is prepended to the helper
+     string, and the result becomes the command.
+
+The resulting command then has an "operation" argument appended to it
+(see below for details), and the result is executed by the shell.
+
+Here are some example specifications:
+
+----------------------------------------------------
+# run "git credential-foo"
+foo
+
+# same as above, but pass an argument to the helper
+foo --bar=baz
+
+# the arguments are parsed by the shell, so use shell
+# quoting if necessary
+foo --bar="whitespace arg"
+
+# you can also use an absolute path, which will not use the git wrapper
+/path/to/my/helper --with-arguments
+
+# or you can specify your own shell snippet
+!f() { echo "password=`cat $HOME/.secret`"; }; f
+----------------------------------------------------
+
+Generally speaking, rule (3) above is the simplest for users to specify.
+Authors of credential helpers should make an effort to assist their
+users by naming their program "git-credential-$NAME", and putting it in
+the $PATH or $GIT_EXEC_PATH during installation, which will allow a user
+to enable it with `git config credential.helper $NAME`.
+
+When a helper is executed, it will have one "operation" argument
+appended to its command line, which is one of:
+
+`get`::
+
+	Return a matching credential, if any exists.
+
+`store`::
+
+	Store the credential, if applicable to the helper.
+
+`erase`::
+
+	Remove a matching credential, if any, from the helper's storage.
+
+The details of the credential will be provided on the helper's stdin
+stream. The exact format is the same as the input/output format of the
+`git credential` plumbing command (see the section `INPUT/OUTPUT
+FORMAT` in linkgit:git-credential[7] for a detailed specification).
+
+For a `get` operation, the helper should produce a list of attributes
+on stdout in the same format. A helper is free to produce a subset, or
+even no values at all if it has nothing useful to provide. Any provided
+attributes will overwrite those already known about by Git.  If a helper
+outputs a `quit` attribute with a value of `true` or `1`, no further
+helpers will be consulted, nor will the user be prompted (if no
+credential has been provided, the operation will then fail).
+
+For a `store` or `erase` operation, the helper's output is ignored.
+If it fails to perform the requested operation, it may complain to
+stderr to inform the user. If it does not support the requested
+operation (e.g., a read-only store), it should silently ignore the
+request.
+
+If a helper receives any other operation, it should silently ignore the
+request. This leaves room for future operations to be added (older
+helpers will just ignore the new requests).

+hashmap API
+===========
+
+The hashmap API is a generic implementation of hash-based key-value mappings.
+
+Data Structures
+---------------
+
+`struct hashmap`::
+
+	The hash table structure. Members can be used as follows, but should
+	not be modified directly:
++
+The `size` member keeps track of the total number of entries (0 means the
+hashmap is empty).
++
+`tablesize` is the allocated size of the hash table. A non-0 value indicates
+that the hashmap is initialized. It may also be useful for statistical purposes
+(i.e. `size / tablesize` is the current load factor).
++
+`cmpfn` stores the comparison function specified in `hashmap_init()`. In
+advanced scenarios, it may be useful to change this, e.g. to switch between
+case-sensitive and case-insensitive lookup.
+
+`struct hashmap_entry`::
+
+	An opaque structure representing an entry in the hash table, which must
+	be used as first member of user data structures. Ideally it should be
+	followed by an int-sized member to prevent unused memory on 64-bit
+	systems due to alignment.
++
+The `hash` member is the entry's hash code and the `next` member points to the
+next entry in case of collisions (i.e. if multiple entries map to the same
+bucket).
+
+`struct hashmap_iter`::
+
+	An iterator structure, to be used with hashmap_iter_* functions.
+
+Types
+-----
+
+`int (*hashmap_cmp_fn)(const void *entry, const void *entry_or_key, const void *keydata)`::
+
+	User-supplied function to test two hashmap entries for equality. Shall
+	return 0 if the entries are equal.
++
+This function is always called with non-NULL `entry` / `entry_or_key`
+parameters that have the same hash code. When looking up an entry, the `key`
+and `keydata` parameters to hashmap_get and hashmap_remove are always passed
+as second and third argument, respectively. Otherwise, `keydata` is NULL.
+
+Functions
+---------
+
+`unsigned int strhash(const char *buf)`::
+`unsigned int strihash(const char *buf)`::
+`unsigned int memhash(const void *buf, size_t len)`::
+`unsigned int memihash(const void *buf, size_t len)`::
+
+	Ready-to-use hash functions for strings, using the FNV-1 algorithm (see
+	http://www.isthe.com/chongo/tech/comp/fnv).
++
+`strhash` and `strihash` take 0-terminated strings, while `memhash` and
+`memihash` operate on arbitrary-length memory.
++
+`strihash` and `memihash` are case insensitive versions.
+
+`unsigned int sha1hash(const unsigned char *sha1)`::
+
+	Converts a cryptographic hash (e.g. SHA-1) into an int-sized hash code
+	for use in hash tables. Cryptographic hashes are supposed to have
+	uniform distribution, so in contrast to `memhash()`, this just copies
+	the first `sizeof(int)` bytes without shuffling any bits. Note that
+	the results will be different on big-endian and little-endian
+	platforms, so they should not be stored or transferred over the net.
+
+`void hashmap_init(struct hashmap *map, hashmap_cmp_fn equals_function, size_t initial_size)`::
+
+	Initializes a hashmap structure.
++
+`map` is the hashmap to initialize.
++
+The `equals_function` can be specified to compare two entries for equality.
+If NULL, entries are considered equal if their hash codes are equal.
++
+If the total number of entries is known in advance, the `initial_size`
+parameter may be used to preallocate a sufficiently large table and thus
+prevent expensive resizing. If 0, the table is dynamically resized.
+
+`void hashmap_free(struct hashmap *map, int free_entries)`::
+
+	Frees a hashmap structure and allocated memory.
++
+`map` is the hashmap to free.
++
+If `free_entries` is true, each hashmap_entry in the map is freed as well
+(using stdlib's free()).
+
+`void hashmap_entry_init(void *entry, unsigned int hash)`::
+
+	Initializes a hashmap_entry structure.
++
+`entry` points to the entry to initialize.
++
+`hash` is the hash code of the entry.
+
+`void *hashmap_get(const struct hashmap *map, const void *key, const void *keydata)`::
+
+	Returns the hashmap entry for the specified key, or NULL if not found.
++
+`map` is the hashmap structure.
++
+`key` is a hashmap_entry structure (or user data structure that starts with
+hashmap_entry) that has at least been initialized with the proper hash code
+(via `hashmap_entry_init`).
++
+If an entry with matching hash code is found, `key` and `keydata` are passed
+to `hashmap_cmp_fn` to decide whether the entry matches the key.
+
+`void *hashmap_get_from_hash(const struct hashmap *map, unsigned int hash, const void *keydata)`::
+
+	Returns the hashmap entry for the specified hash code and key data,
+	or NULL if not found.
++
+`map` is the hashmap structure.
++
+`hash` is the hash code of the entry to look up.
++
+If an entry with matching hash code is found, `keydata` is passed to
+`hashmap_cmp_fn` to decide whether the entry matches the key. The
+`entry_or_key` parameter points to a bogus hashmap_entry structure that
+should not be used in the comparison.
+
+`void *hashmap_get_next(const struct hashmap *map, const void *entry)`::
+
+	Returns the next equal hashmap entry, or NULL if not found. This can be
+	used to iterate over duplicate entries (see `hashmap_add`).
++
+`map` is the hashmap structure.
++
+`entry` is the hashmap_entry to start the search from, obtained via a previous
+call to `hashmap_get` or `hashmap_get_next`.
+
+`void hashmap_add(struct hashmap *map, void *entry)`::
+
+	Adds a hashmap entry. This allows to add duplicate entries (i.e.
+	separate values with the same key according to hashmap_cmp_fn).
++
+`map` is the hashmap structure.
++
+`entry` is the entry to add.
+
+`void *hashmap_put(struct hashmap *map, void *entry)`::
+
+	Adds or replaces a hashmap entry. If the hashmap contains duplicate
+	entries equal to the specified entry, only one of them will be replaced.
++
+`map` is the hashmap structure.
++
+`entry` is the entry to add or replace.
++
+Returns the replaced entry, or NULL if not found (i.e. the entry was added).
+
+`void *hashmap_remove(struct hashmap *map, const void *key, const void *keydata)`::
+
+	Removes a hashmap entry matching the specified key. If the hashmap
+	contains duplicate entries equal to the specified key, only one of
+	them will be removed.
++
+`map` is the hashmap structure.
++
+`key` is a hashmap_entry structure (or user data structure that starts with
+hashmap_entry) that has at least been initialized with the proper hash code
+(via `hashmap_entry_init`).
++
+If an entry with matching hash code is found, `key` and `keydata` are
+passed to `hashmap_cmp_fn` to decide whether the entry matches the key.
++
+Returns the removed entry, or NULL if not found.
+
+`void hashmap_iter_init(struct hashmap *map, struct hashmap_iter *iter)`::
+`void *hashmap_iter_next(struct hashmap_iter *iter)`::
+`void *hashmap_iter_first(struct hashmap *map, struct hashmap_iter *iter)`::
+
+	Used to iterate over all entries of a hashmap.
++
+`hashmap_iter_init` initializes a `hashmap_iter` structure.
++
+`hashmap_iter_next` returns the next hashmap_entry, or NULL if there are no
+more entries.
++
+`hashmap_iter_first` is a combination of both (i.e. initializes the iterator
+and returns the first entry, if any).
+
+`const char *strintern(const char *string)`::
+`const void *memintern(const void *data, size_t len)`::
+
+	Returns the unique, interned version of the specified string or data,
+	similar to the `String.intern` API in Java and .NET, respectively.
+	Interned strings remain valid for the entire lifetime of the process.
++
+Can be used as `[x]strdup()` or `xmemdupz` replacement, except that interned
+strings / data must not be modified or freed.
++
+Interned strings are best used for short strings with high probability of
+duplicates.
++
+Uses a hashmap to store the pool of interned strings.
+
+Usage example
+-------------
+
+Here's a simple usage example that maps long keys to double values.
+------------
+struct hashmap map;
+
+struct long2double {
+	struct hashmap_entry ent; /* must be the first member! */
+	long key;
+	double value;
+};
+
+static int long2double_cmp(const struct long2double *e1, const struct long2double *e2, const void *unused)
+{
+	return !(e1->key == e2->key);
+}
+
+void long2double_init(void)
+{
+	hashmap_init(&map, (hashmap_cmp_fn) long2double_cmp, 0);
+}
+
+void long2double_free(void)
+{
+	hashmap_free(&map, 1);
+}
+
+static struct long2double *find_entry(long key)
+{
+	struct long2double k;
+	hashmap_entry_init(&k, memhash(&key, sizeof(long)));
+	k.key = key;
+	return hashmap_get(&map, &k, NULL);
+}
+
+double get_value(long key)
+{
+	struct long2double *e = find_entry(key);
+	return e ? e->value : 0;
+}
+
+void set_value(long key, double value)
+{
+	struct long2double *e = find_entry(key);
+	if (!e) {
+		e = malloc(sizeof(struct long2double));
+		hashmap_entry_init(e, memhash(&key, sizeof(long)));
+		e->key = key;
+		hashmap_add(&map, e);
+	}
+	e->value = value;
+}
+------------
+
+Using variable-sized keys
+-------------------------
+
+The `hashmap_entry_get` and `hashmap_entry_remove` functions expect an ordinary
+`hashmap_entry` structure as key to find the correct entry. If the key data is
+variable-sized (e.g. a FLEX_ARRAY string) or quite large, it is undesirable
+to create a full-fledged entry structure on the heap and copy all the key data
+into the structure.
+
+In this case, the `keydata` parameter can be used to pass
+variable-sized key data directly to the comparison function, and the `key`
+parameter can be a stripped-down, fixed size entry structure allocated on the
+stack.
+
+See test-hashmap.c for an example using arbitrary-length strings as keys.

 The lockfile API serves two purposes:
 
-* Mutual exclusion.  When we write out a new index file, first
-  we create a new file `$GIT_DIR/index.lock`, write the new
-  contents into it, and rename it to the final destination
-  `$GIT_DIR/index`.  We try to create the `$GIT_DIR/index.lock`
-  file with O_EXCL so that we can notice and fail when somebody
-  else is already trying to update the index file.
-
-* Automatic cruft removal.  After we create the "lock" file, we
-  may decide to `die()`, and we would want to make sure that we
-  remove the file that has not been committed to its final
-  destination.  This is done by remembering the lockfiles we
-  created in a linked list and cleaning them up from an
-  `atexit(3)` handler.  Outstanding lockfiles are also removed
-  when the program dies on a signal.
+* Mutual exclusion and atomic file updates. When we want to change a
+  file, we create a lockfile `<filename>.lock`, write the new file
+  contents into it, and then rename the lockfile to its final
+  destination `<filename>`. We create the `<filename>.lock` file with
+  `O_CREAT|O_EXCL` so that we can notice and fail if somebody else has
+  already locked the file, then atomically rename the lockfile to its
+  final destination to commit the changes and unlock the file.
+
+* Automatic cruft removal. If the program exits after we lock a file
+  but before the changes have been committed, we want to make sure
+  that we remove the lockfile. This is done by remembering the
+  lockfiles we have created in a linked list and setting up an
+  `atexit(3)` handler and a signal handler that clean up the
+  lockfiles. This mechanism ensures that outstanding lockfiles are
+  cleaned up if the program exits (including when `die()` is called)
+  or if the program dies on a signal.
+
+Please note that lockfiles only block other writers. Readers do not
+block, but they are guaranteed to see either the old contents of the
+file or the new contents of the file (assuming that the filesystem
+implements `rename(2)` atomically).
+
+
+Calling sequence
+----------------
+
+The caller:
+
+* Allocates a `struct lock_file` either as a static variable or on the
+  heap, initialized to zeros. Once you use the structure to call the
+  `hold_lock_file_*` family of functions, it belongs to the lockfile
+  subsystem and its storage must remain valid throughout the life of
+  the program (i.e. you cannot use an on-stack variable to hold this
+  structure).
+
+* Attempts to create a lockfile by passing that variable and the path
+  of the final destination (e.g. `$GIT_DIR/index`) to
+  `hold_lock_file_for_update` or `hold_lock_file_for_append`.
+
+* Writes new content for the destination file by either:
+
+  * writing to the file descriptor returned by the `hold_lock_file_*`
+    functions (also available via `lock->fd`).
+
+  * calling `fdopen_lock_file` to get a `FILE` pointer for the open
+    file and writing to the file using stdio.
+
+When finished writing, the caller can:
+
+* Close the file descriptor and rename the lockfile to its final
+  destination by calling `commit_lock_file` or `commit_lock_file_to`.
+
+* Close the file descriptor and remove the lockfile by calling
+  `rollback_lock_file`.
+
+* Close the file descriptor without removing or renaming the lockfile
+  by calling `close_lock_file`, and later call `commit_lock_file`,
+  `commit_lock_file_to`, `rollback_lock_file`, or `reopen_lock_file`.
+
+Even after the lockfile is committed or rolled back, the `lock_file`
+object must not be freed or altered by the caller. However, it may be
+reused; just pass it to another call of `hold_lock_file_for_update` or
+`hold_lock_file_for_append`.
+
+If the program exits before you have called one of `commit_lock_file`,
+`commit_lock_file_to`, `rollback_lock_file`, or `close_lock_file`, an
+`atexit(3)` handler will close and remove the lockfile, rolling back
+any uncommitted changes.
+
+If you need to close the file descriptor you obtained from a
+`hold_lock_file_*` function yourself, do so by calling
+`close_lock_file`. You should never call `close(2)` or `fclose(3)`
+yourself! Otherwise the `struct lock_file` structure would still think
+that the file descriptor needs to be closed, and a commit or rollback
+would result in duplicate calls to `close(2)`. Worse yet, if you close
+and then later open another file descriptor for a completely different
+purpose, then a commit or rollback might close that unrelated file
+descriptor.
+
+
+Error handling
+--------------
+
+The `hold_lock_file_*` functions return a file descriptor on success
+or -1 on failure (unless `LOCK_DIE_ON_ERROR` is used; see below). On
+errors, `errno` describes the reason for failure. Errors can be
+reported by passing `errno` to one of the following helper functions:
+
+unable_to_lock_message::
+
+	Append an appropriate error message to a `strbuf`.
+
+unable_to_lock_error::
+
+	Emit an appropriate error message using `error()`.
+
+unable_to_lock_die::
+
+	Emit an appropriate error message and `die()`.
+
+Similarly, `commit_lock_file`, `commit_lock_file_to`, and
+`close_lock_file` return 0 on success. On failure they set `errno`
+appropriately, do their best to roll back the lockfile, and return -1.
+
+
+Flags
+-----
+
+The following flags can be passed to `hold_lock_file_for_update` or
+`hold_lock_file_for_append`:
+
+LOCK_NO_DEREF::
+
+	Usually symbolic links in the destination path are resolved
+	and the lockfile is created by adding ".lock" to the resolved
+	path. If `LOCK_NO_DEREF` is set, then the lockfile is created
+	by adding ".lock" to the path argument itself. This option is
+	used, for example, when locking a symbolic reference, which
+	for backwards-compatibility reasons can be a symbolic link
+	containing the name of the referred-to-reference.
+
+LOCK_DIE_ON_ERROR::
+
+	If a lock is already taken for the file, `die()` with an error
+	message. If this option is not specified, trying to lock a
+	file that is already locked returns -1 to the caller.

+
+	* Write new contents to lockfile, then `close_lock_file` to
+	  cause the contents to be written to disk.
+
+	* Pass the name of the lockfile to another program to allow it
+	  (and nobody else) to inspect the contents you wrote, while
+	  still holding the lock yourself.
+
+	* `reopen_lock_file` to reopen the lockfile. Make further
+	  updates to the contents.
+
+	* `commit_lock_file` to make the final version permanent.

+
+ * lining up corresponding files in the trees to be merged (rename

+   and rename/rename conflicts to the user;
+
+ * performing a three-way merge of corresponding files, taking
+   path-specific merge drivers (specified in `.gitattributes`)
+   into account.
+
+Data structures
+---------------
+
+* `mmbuffer_t`, `mmfile_t`
+
+These store data usable for use by the xdiff backend, for writing and
+for reading, respectively.  See `xdiff/xdiff.h` for the definitions
+and `diff.c` for examples.
+
+* `struct ll_merge_options`
+
+This describes the set of options the calling program wants to affect
+the operation of a low-level (single file) merge.  Some options:
+
+`virtual_ancestor`::
+	Behave as though this were part of a merge between common
+	ancestors in a recursive merge.
+	If a helper program is specified by the
+	`[merge "<driver>"] recursive` configuration, it will
+	be used (see linkgit:gitattributes[5]).
+
+`variant`::
+	Resolve local conflicts automatically in favor
+	of one side or the other (as in 'git merge-file'
+	`--ours`/`--theirs`/`--union`).  Can be `0`,
+	`XDL_MERGE_FAVOR_OURS`, `XDL_MERGE_FAVOR_THEIRS`, or
+	`XDL_MERGE_FAVOR_UNION`.
+
+`renormalize`::
+	Resmudge and clean the "base", "theirs" and "ours" files
+	before merging.  Use this when the merge is likely to have
+	overlapped with a change in smudge/clean or end-of-line
+	normalization rules.
+
+Low-level (single file) merge
+-----------------------------
+
+`ll_merge`::
+
+	Perform a three-way single-file merge in core.  This is
+	a thin wrapper around `xdl_merge` that takes the path and
+	any merge backend specified in `.gitattributes` or
+	`.git/info/attributes` into account.  Returns 0 for a
+	clean merge.
+
+Calling sequence:
+
+* Prepare a `struct ll_merge_options` to record options.
+  If you have no special requests, skip this and pass `NULL`
+  as the `opts` parameter to use the default options.
+
+* Allocate an mmbuffer_t variable for the result.
+
+* Allocate and fill variables with the file's original content
+  and two modified versions (using `read_mmfile`, for example).
+
+* Call `ll_merge()`.
+
+* Read the merged content from `result_buf.ptr` and `result_buf.size`.
+
+* Release buffers when finished.  A simple
+  `free(ancestor.ptr); free(ours.ptr); free(theirs.ptr);
+  free(result_buf.ptr);` will do.
+
+If the modifications do not merge cleanly, `ll_merge` will return a
+nonzero value and `result_buf` will generally include a description of
+the conflict bracketed by markers such as the traditional `<<<<<<<`
+and `>>>>>>>`.
+
+The `ancestor_label`, `our_label`, and `their_label` parameters are
+used to label the different sides of a conflict if the merge driver
+supports this.
+

+ref iteration API
+=================
+
+
+Iteration of refs is done by using an iterate function which will call a
+callback function for every ref. The callback function has this
+signature:
+
+	int handle_one_ref(const char *refname, const unsigned char *sha1,
+			   int flags, void *cb_data);
+
+There are different kinds of iterate functions which all take a
+callback of this type. The callback is then called for each found ref
+until the callback returns nonzero. The returned value is then also
+returned by the iterate function.
+
+Iteration functions
+-------------------
+
+* `head_ref()` just iterates the head ref.
+
+* `for_each_ref()` iterates all refs.
+
+* `for_each_ref_in()` iterates all refs which have a defined prefix and
+  strips that prefix from the passed variable refname.
+
+* `for_each_tag_ref()`, `for_each_branch_ref()`, `for_each_remote_ref()`,
+  `for_each_replace_ref()` iterate refs from the respective area.
+
+* `for_each_glob_ref()` iterates all refs that match the specified glob
+  pattern.
+
+* `for_each_glob_ref_in()` the previous and `for_each_ref_in()` combined.
+
+* `head_ref_submodule()`, `for_each_ref_submodule()`,
+  `for_each_ref_in_submodule()`, `for_each_tag_ref_submodule()`,
+  `for_each_branch_ref_submodule()`, `for_each_remote_ref_submodule()`
+  do the same as the functions described above but for a specified
+  submodule.
+
+* `for_each_rawref()` can be used to learn about broken ref and symref.
+
+* `for_each_reflog()` iterates each reflog file.
+
+Submodules
+----------
+
+If you want to iterate the refs of a submodule you first need to add the
+submodules object database. You can do this by a code-snippet like
+this:
+
+	const char *path = "path/to/submodule"
+	if (add_submodule_odb(path))
+		die("Error submodule '%s' not populated.", path);
+
+`add_submodule_odb()` will return zero on success. If you
+do not do this you will get an error for each ref that it does not point
+to a valid object.
+
+Note: As a side-effect of this you can not safely assume that all
+objects you lookup are available in superproject. All submodule objects
+will be available the same way as the superprojects objects.
+
+Example:
+--------
+
+----
+static int handle_remote_ref(const char *refname,
+		const unsigned char *sha1, int flags, void *cb_data)
+{
+	struct strbuf *output = cb_data;
+	strbuf_addf(output, "%s\n", refname);
+	return 0;
+}
+
+...
+
+	struct strbuf output = STRBUF_INIT;
+	for_each_remote_ref(handle_remote_ref, &output);
+	printf("%s", output.buf);

+Pathspec
+--------
+
+See glossary-context.txt for the syntax of pathspec. In memory, a
+pathspec set is represented by "struct pathspec" and is prepared by
+parse_pathspec(). This function takes several arguments:
+
+- magic_mask specifies what features that are NOT supported by the
+  following code. If a user attempts to use such a feature,
+  parse_pathspec() can reject it early.
+
+- flags specifies other things that the caller wants parse_pathspec to
+  perform.
+
+- prefix and args come from cmd_* functions
+
+get_pathspec() is obsolete and should never be used in new code.
+
+parse_pathspec() helps catch unsupported features and reject them
+politely. At a lower level, different pathspec-related functions may
+not support the same set of features. Such pathspec-sensitive
+functions are guarded with GUARD_PATHSPEC(), which will die in an
+unfriendly way when an unsupported feature is requested.
+
+The command designers are supposed to make sure that GUARD_PATHSPEC()
+never dies. They have to make sure all unsupported features are caught
+by parse_pathspec(), not by GUARD_PATHSPEC. grepping GUARD_PATHSPEC()
+should give the designers all pathspec-sensitive codepaths and what

+sha1-array API
+==============
+
+The sha1-array API provides storage and manipulation of sets of SHA-1
+identifiers. The emphasis is on storage and processing efficiency,
+making them suitable for large lists. Note that the ordering of items is
+not preserved over some operations.
+
+Data Structures
+---------------
+
+`struct sha1_array`::
+
+	A single array of SHA-1 hashes. This should be initialized by
+	assignment from `SHA1_ARRAY_INIT`.  The `sha1` member contains
+	the actual data. The `nr` member contains the number of items in
+	the set.  The `alloc` and `sorted` members are used internally,
+	and should not be needed by API callers.
+
+Functions
+---------
+
+`sha1_array_append`::
+	Add an item to the set. The sha1 will be placed at the end of
+	the array (but note that some operations below may lose this
+	ordering).
+
+`sha1_array_lookup`::
+	Perform a binary search of the array for a specific sha1.
+	If found, returns the offset (in number of elements) of the
+	sha1. If not found, returns a negative integer. If the array is
+	not sorted, this function has the side effect of sorting it.
+
+`sha1_array_clear`::
+	Free all memory associated with the array and return it to the
+	initial, empty state.
+
+`sha1_array_for_each_unique`::
+	Efficiently iterate over each unique element of the list,
+	executing the callback function for each one. If the array is
+	not sorted, this function has the side effect of sorting it.
+
+Examples
+--------
+
+-----------------------------------------
+void print_callback(const unsigned char sha1[20],
+		    void *data)
+{
+	printf("%s\n", sha1_to_hex(sha1));
+}
+
+void some_func(void)
+{
+	struct sha1_array hashes = SHA1_ARRAY_INIT;
+	unsigned char sha1[20];
+
+	/* Read objects into our set */
+	while (read_object_from_stdin(sha1))
+		sha1_array_append(&hashes, sha1);
+
+	/* Check if some objects are in our set */
+	while (read_object_from_stdin(sha1)) {
+		if (sha1_array_lookup(&hashes, sha1) >= 0)
+			printf("it's in there!\n");
+
+	/*
+	 * Print the unique set of objects. We could also have
+	 * avoided adding duplicate objects in the first place,
+	 * but we would end up re-sorting the array repeatedly.
+	 * Instead, this will sort once and then skip duplicates
+	 * in linear time.
+	 */
+	sha1_array_for_each_unique(&hashes, print_callback, NULL);

+sigchain API
+============
+
+Code often wants to set a signal handler to clean up temporary files or
+other work-in-progress when we die unexpectedly. For multiple pieces of
+code to do this without conflicting, each piece of code must remember
+the old value of the handler and restore it either when:
+
+  1. The work-in-progress is finished, and the handler is no longer
+     necessary. The handler should revert to the original behavior
+     (either another handler, SIG_DFL, or SIG_IGN).
+
+  2. The signal is received. We should then do our cleanup, then chain
+     to the next handler (or die if it is SIG_DFL).
+
+Sigchain is a tiny library for keeping a stack of handlers. Your handler
+and installation code should look something like:
+
+------------------------------------------
+  void clean_foo_on_signal(int sig)
+  {
+	  clean_foo();
+	  sigchain_pop(sig);
+	  raise(sig);
+  }
+
+  void other_func()
+  {
+	  sigchain_push_common(clean_foo_on_signal);
+	  mess_up_foo();
+	  clean_foo();
+  }
+------------------------------------------
+
+Handlers are given the typedef of sigchain_fun. This is the same type
+that is given to signal() or sigaction(). It is perfectly reasonable to
+push SIG_DFL or SIG_IGN onto the stack.
+
+You can sigchain_push and sigchain_pop individual signals. For
+convenience, sigchain_push_common will push the handler onto the stack
+for many common signals.

+GIT bitmap v1 format
+====================
+
+	- A header appears at the beginning:
+
+		4-byte signature: {'B', 'I', 'T', 'M'}
+
+		2-byte version number (network byte order)
+			The current implementation only supports version 1
+			of the bitmap index (the same one as JGit).
+
+		2-byte flags (network byte order)
+
+			The following flags are supported:
+
+			- BITMAP_OPT_FULL_DAG (0x1) REQUIRED
+			This flag must always be present. It implies that the bitmap
+			index has been generated for a packfile with full closure
+			(i.e. where every single object in the packfile can find
+			 its parent links inside the same packfile). This is a
+			requirement for the bitmap index format, also present in JGit,
+			that greatly reduces the complexity of the implementation.
+
+			- BITMAP_OPT_HASH_CACHE (0x4)
+			If present, the end of the bitmap file contains
+			`N` 32-bit name-hash values, one per object in the
+			pack. The format and meaning of the name-hash is
+			described below.
+
+		4-byte entry count (network byte order)
+
+			The total count of entries (bitmapped commits) in this bitmap index.
+
+		20-byte checksum
+
+			The SHA1 checksum of the pack this bitmap index belongs to.
+
+	- 4 EWAH bitmaps that act as type indexes
+
+		Type indexes are serialized after the hash cache in the shape
+		of four EWAH bitmaps stored consecutively (see Appendix A for
+		the serialization format of an EWAH bitmap).
+
+		There is a bitmap for each Git object type, stored in the following
+		order:
+
+			- Commits
+			- Trees
+			- Blobs
+			- Tags
+
+		In each bitmap, the `n`th bit is set to true if the `n`th object
+		in the packfile is of that type.
+
+		The obvious consequence is that the OR of all 4 bitmaps will result
+		in a full set (all bits set), and the AND of all 4 bitmaps will
+		result in an empty bitmap (no bits set).
+
+	- N entries with compressed bitmaps, one for each indexed commit
+
+		Where `N` is the total amount of entries in this bitmap index.
+		Each entry contains the following:
+
+		- 4-byte object position (network byte order)
+			The position **in the index for the packfile** where the
+			bitmap for this commit is found.
+
+		- 1-byte XOR-offset
+			The xor offset used to compress this bitmap. For an entry
+			in position `x`, a XOR offset of `y` means that the actual
+			bitmap representing this commit is composed by XORing the
+			bitmap for this entry with the bitmap in entry `x-y` (i.e.
+			the bitmap `y` entries before this one).
+
+			Note that this compression can be recursive. In order to
+			XOR this entry with a previous one, the previous entry needs
+			to be decompressed first, and so on.
+
+			The hard-limit for this offset is 160 (an entry can only be
+			xor'ed against one of the 160 entries preceding it). This
+			number is always positive, and hence entries are always xor'ed
+			with **previous** bitmaps, not bitmaps that will come afterwards
+			in the index.
+
+		- 1-byte flags for this bitmap
+			At the moment the only available flag is `0x1`, which hints
+			that this bitmap can be re-used when rebuilding bitmap indexes
+			for the repository.
+
+		- The compressed bitmap itself, see Appendix A.
+
+== Appendix A: Serialization format for an EWAH bitmap
+
+Ewah bitmaps are serialized in the same protocol as the JAVAEWAH
+library, making them backwards compatible with the JGit
+implementation:
+
+	- 4-byte number of bits of the resulting UNCOMPRESSED bitmap
+
+	- 4-byte number of words of the COMPRESSED bitmap, when stored
+
+	- N x 8-byte words, as specified by the previous field
+
+		This is the actual content of the compressed bitmap.
+
+	- 4-byte position of the current RLW for the compressed
+		bitmap
+
+All words are stored in network byte order for their corresponding
+sizes.
+
+The compressed bitmap is stored in a form of run-length encoding, as
+follows.  It consists of a concatenation of an arbitrary number of
+chunks.  Each chunk consists of one or more 64-bit words
+
+     H  L_1  L_2  L_3 .... L_M
+
+H is called RLW (run length word).  It consists of (from lower to higher
+order bits):
+
+     - 1 bit: the repeated bit B
+
+     - 32 bits: repetition count K (unsigned)
+
+     - 31 bits: literal word count M (unsigned)
+
+The bitstream represented by the above chunk is then:
+
+     - K repetitions of B
+
+     - The bits stored in `L_1` through `L_M`.  Within a word, bits at
+       lower order come earlier in the stream than those at higher
+       order.
+
+The next word after `L_M` (if any) must again be a RLW, for the next
+chunk.  For efficient appending to the bitstream, the EWAH stores a
+pointer to the last RLW in the stream.
+
+
+== Appendix B: Optional Bitmap Sections
+
+These sections may or may not be present in the `.bitmap` file; their
+presence is indicated by the header flags section described above.
+
+Name-hash cache
+---------------
+
+If the BITMAP_OPT_HASH_CACHE flag is set, the end of the bitmap contains
+a cache of 32-bit values, one per object in the pack. The value at
+position `i` is the hash of the pathname at which the `i`th object
+(counting in index order) in the pack can be found.  This can be fed
+into the delta heuristics to compare objects with similar pathnames.
+
+The hash algorithm used is:
+
+    hash = 0;
+    while ((c = *name++))
+	    if (!isspace(c))
+		    hash = (hash >> 2) + (c << 24);
+
+Note that this hashing scheme is tied to the BITMAP_OPT_HASH_CACHE flag.
+If implementations want to choose a different hashing scheme, they are
+free to do so, but MUST allocate a new header flag (because comparing
+hashes made under two different schemes would be pointless).

+HTTP transfer protocols
+=======================
+
+Git supports two HTTP based transfer protocols.  A "dumb" protocol
+which requires only a standard HTTP server on the server end of the
+connection, and a "smart" protocol which requires a Git aware CGI
+(or server module).  This document describes both protocols.
+
+As a design feature smart clients can automatically upgrade "dumb"
+protocol URLs to smart URLs.  This permits all users to have the
+same published URL, and the peers automatically select the most
+efficient transport available to them.
+
+
+URL Format
+----------
+
+URLs for Git repositories accessed by HTTP use the standard HTTP
+URL syntax documented by RFC 1738, so they are of the form:
+
+  http://<host>:<port>/<path>?<searchpart>
+
+Within this documentation the placeholder `$GIT_URL` will stand for
+the http:// repository URL entered by the end-user.
+
+Servers SHOULD handle all requests to locations matching `$GIT_URL`, as
+both the "smart" and "dumb" HTTP protocols used by Git operate
+by appending additional path components onto the end of the user
+supplied `$GIT_URL` string.
+
+An example of a dumb client requesting for a loose object:
+
+  $GIT_URL:     http://example.com:8080/git/repo.git
+  URL request:  http://example.com:8080/git/repo.git/objects/d0/49f6c27a2244e12041955e262a404c7faba355
+
+An example of a smart request to a catch-all gateway:
+
+  $GIT_URL:     http://example.com/daemon.cgi?svc=git&q=
+  URL request:  http://example.com/daemon.cgi?svc=git&q=/info/refs&service=git-receive-pack
+
+An example of a request to a submodule:
+
+  $GIT_URL:     http://example.com/git/repo.git/path/submodule.git
+  URL request:  http://example.com/git/repo.git/path/submodule.git/info/refs
+
+Clients MUST strip a trailing `/`, if present, from the user supplied
+`$GIT_URL` string to prevent empty path tokens (`//`) from appearing
+in any URL sent to a server.  Compatible clients MUST expand
+`$GIT_URL/info/refs` as `foo/info/refs` and not `foo//info/refs`.
+
+
+Authentication
+--------------
+
+Standard HTTP authentication is used if authentication is required
+to access a repository, and MAY be configured and enforced by the
+HTTP server software.
+
+Because Git repositories are accessed by standard path components
+server administrators MAY use directory based permissions within
+their HTTP server to control repository access.
+
+Clients SHOULD support Basic authentication as described by RFC 2617.
+Servers SHOULD support Basic authentication by relying upon the
+HTTP server placed in front of the Git server software.
+
+Servers SHOULD NOT require HTTP cookies for the purposes of
+authentication or access control.
+
+Clients and servers MAY support other common forms of HTTP based
+authentication, such as Digest authentication.
+
+
+SSL
+---
+
+Clients and servers SHOULD support SSL, particularly to protect
+passwords when relying on Basic HTTP authentication.
+
+
+Session State
+-------------
+
+The Git over HTTP protocol (much like HTTP itself) is stateless
+from the perspective of the HTTP server side.  All state MUST be
+retained and managed by the client process.  This permits simple
+round-robin load-balancing on the server side, without needing to
+worry about state management.
+
+Clients MUST NOT require state management on the server side in
+order to function correctly.
+
+Servers MUST NOT require HTTP cookies in order to function correctly.
+Clients MAY store and forward HTTP cookies during request processing
+as described by RFC 2616 (HTTP/1.1).  Servers SHOULD ignore any
+cookies sent by a client.
+
+
+General Request Processing
+--------------------------
+
+Except where noted, all standard HTTP behavior SHOULD be assumed
+by both client and server.  This includes (but is not necessarily
+limited to):
+
+If there is no repository at `$GIT_URL`, or the resource pointed to by a
+location matching `$GIT_URL` does not exist, the server MUST NOT respond
+with `200 OK` response.  A server SHOULD respond with
+`404 Not Found`, `410 Gone`, or any other suitable HTTP status code
+which does not imply the resource exists as requested.
+
+If there is a repository at `$GIT_URL`, but access is not currently
+permitted, the server MUST respond with the `403 Forbidden` HTTP
+status code.
+
+Servers SHOULD support both HTTP 1.0 and HTTP 1.1.
+Servers SHOULD support chunked encoding for both request and response
+bodies.
+
+Clients SHOULD support both HTTP 1.0 and HTTP 1.1.
+Clients SHOULD support chunked encoding for both request and response
+bodies.
+
+Servers MAY return ETag and/or Last-Modified headers.
+
+Clients MAY revalidate cached entities by including If-Modified-Since
+and/or If-None-Match request headers.
+
+Servers MAY return `304 Not Modified` if the relevant headers appear
+in the request and the entity has not changed.  Clients MUST treat
+`304 Not Modified` identical to `200 OK` by reusing the cached entity.
+
+Clients MAY reuse a cached entity without revalidation if the
+Cache-Control and/or Expires header permits caching.  Clients and
+servers MUST follow RFC 2616 for cache controls.
+
+
+Discovering References
+----------------------
+
+All HTTP clients MUST begin either a fetch or a push exchange by
+discovering the references available on the remote repository.
+
+Dumb Clients
+~~~~~~~~~~~~
+
+HTTP clients that only support the "dumb" protocol MUST discover
+references by making a request for the special info/refs file of
+the repository.
+
+Dumb HTTP clients MUST make a `GET` request to `$GIT_URL/info/refs`,
+without any search/query parameters.
+
+   C: GET $GIT_URL/info/refs HTTP/1.0
+
+   S: 200 OK
+   S:
+   S: 95dcfa3633004da0049d3d0fa03f80589cbcaf31	refs/heads/maint
+   S: d049f6c27a2244e12041955e262a404c7faba355	refs/heads/master
+   S: 2cb58b79488a98d2721cea644875a8dd0026b115	refs/tags/v1.0
+   S: a3c2e2402b99163d1d59756e5f207ae21cccba4c	refs/tags/v1.0^{}
+
+The Content-Type of the returned info/refs entity SHOULD be
+`text/plain; charset=utf-8`, but MAY be any content type.
+Clients MUST NOT attempt to validate the returned Content-Type.
+Dumb servers MUST NOT return a return type starting with
+`application/x-git-`.
+
+Cache-Control headers MAY be returned to disable caching of the
+returned entity.
+
+When examining the response clients SHOULD only examine the HTTP
+status code.  Valid responses are `200 OK`, or `304 Not Modified`.
+
+The returned content is a UNIX formatted text file describing
+each ref and its known value.  The file SHOULD be sorted by name
+according to the C locale ordering.  The file SHOULD NOT include
+the default ref named `HEAD`.
+
+  info_refs   =  *( ref_record )
+  ref_record  =  any_ref / peeled_ref
+
+  any_ref     =  obj-id HTAB refname LF
+  peeled_ref  =  obj-id HTAB refname LF
+		 obj-id HTAB refname "^{}" LF
+
+Smart Clients
+~~~~~~~~~~~~~
+
+HTTP clients that support the "smart" protocol (or both the
+"smart" and "dumb" protocols) MUST discover references by making
+a parameterized request for the info/refs file of the repository.
+
+The request MUST contain exactly one query parameter,
+`service=$servicename`, where `$servicename` MUST be the service
+name the client wishes to contact to complete the operation.
+The request MUST NOT contain additional query parameters.
+
+   C: GET $GIT_URL/info/refs?service=git-upload-pack HTTP/1.0
+

+
+Dumb Server Response
+^^^^^^^^^^^^^^^^^^^^
+Dumb servers MUST respond with the dumb server reply format.
+
+See the prior section under dumb clients for a more detailed
+description of the dumb server response.
+
+Smart Server Response
+^^^^^^^^^^^^^^^^^^^^^
+If the server does not recognize the requested service name, or the
+requested service name has been disabled by the server administrator,
+the server MUST respond with the `403 Forbidden` HTTP status code.
+
+Otherwise, smart servers MUST respond with the smart server reply
+format for the requested service name.
+
+Cache-Control headers SHOULD be used to disable caching of the
+returned entity.
+
+The Content-Type MUST be `application/x-$servicename-advertisement`.
+Clients SHOULD fall back to the dumb protocol if another content
+type is returned.  When falling back to the dumb protocol clients
+SHOULD NOT make an additional request to `$GIT_URL/info/refs`, but
+instead SHOULD use the response already in hand.  Clients MUST NOT
+continue if they do not support the dumb protocol.
+
+Clients MUST validate the status code is either `200 OK` or
+`304 Not Modified`.
+
+Clients MUST validate the first five bytes of the response entity
+matches the regex `^[0-9a-f]{4}#`.  If this test fails, clients
+MUST NOT continue.
+
+Clients MUST parse the entire response as a sequence of pkt-line
+records.
+
+Clients MUST verify the first pkt-line is `# service=$servicename`.
+Servers MUST set $servicename to be the request parameter value.
+Servers SHOULD include an LF at the end of this line.
+Clients MUST ignore an LF at the end of the line.
+
+Servers MUST terminate the response with the magic `0000` end
+pkt-line marker.
+
+The returned response is a pkt-line stream describing each ref and
+its known value.  The stream SHOULD be sorted by name according to
+the C locale ordering.  The stream SHOULD include the default ref
+named `HEAD` as the first ref.  The stream MUST include capability
+declarations behind a NUL on the first ref.
+
+  smart_reply     =  PKT-LINE("# service=$servicename" LF)
+		     ref_list
+		     "0000"
+  ref_list        =  empty_list / non_empty_list
+
+  empty_list      =  PKT-LINE(zero-id SP "capabilities^{}" NUL cap-list LF)
+
+  non_empty_list  =  PKT-LINE(obj-id SP name NUL cap_list LF)
+		     *ref_record
+
+  cap-list        =  capability *(SP capability)
+  capability      =  1*(LC_ALPHA / DIGIT / "-" / "_")
+  LC_ALPHA        =  %x61-7A
+
+  ref_record      =  any_ref / peeled_ref
+  any_ref         =  PKT-LINE(obj-id SP name LF)
+  peeled_ref      =  PKT-LINE(obj-id SP name LF)
+		     PKT-LINE(obj-id SP name "^{}" LF
+
+
+Smart Service git-upload-pack
+------------------------------
+This service reads from the repository pointed to by `$GIT_URL`.
+
+Clients MUST first perform ref discovery with
+`$GIT_URL/info/refs?service=git-upload-pack`.
+
+   C: POST $GIT_URL/git-upload-pack HTTP/1.0
+   C: Content-Type: application/x-git-upload-pack-request
+   C:
+   C: 0032want 0a53e9ddeaddad63ad106860237bbf53411d11a7\n
+   C: 0032have 441b40d833fdfa93eb2908e52742248faf0ee993\n
+   C: 0000
+
+   S: 200 OK
+   S: Content-Type: application/x-git-upload-pack-result
+   S: Cache-Control: no-cache
+   S:
+   S: ....ACK %s, continue
+   S: ....NAK
+
+Clients MUST NOT reuse or revalidate a cached response.
+Servers MUST include sufficient Cache-Control headers
+to prevent caching of the response.
+
+Servers SHOULD support all capabilities defined here.
+
+Clients MUST send at least one "want" command in the request body.
+Clients MUST NOT reference an id in a "want" command which did not
+appear in the response obtained through ref discovery unless the
+server advertises capability `allow-tip-sha1-in-want`.
+
+  compute_request   =  want_list
+		       have_list
+		       request_end
+  request_end       =  "0000" / "done"
+
+  want_list         =  PKT-LINE(want NUL cap_list LF)
+		       *(want_pkt)
+  want_pkt          =  PKT-LINE(want LF)
+  want              =  "want" SP id
+  cap_list          =  *(SP capability) SP
+
+  have_list         =  *PKT-LINE("have" SP id LF)
+
+TODO: Document this further.
+
+The Negotiation Algorithm
+~~~~~~~~~~~~~~~~~~~~~~~~~
+The computation to select the minimal pack proceeds as follows
+(C = client, S = server):
+
+'init step:'
+
+C: Use ref discovery to obtain the advertised refs.
+
+C: Place any object seen into set `advertised`.
+
+C: Build an empty set, `common`, to hold the objects that are later
+   determined to be on both ends.
+
+C: Build a set, `want`, of the objects from `advertised` the client
+   wants to fetch, based on what it saw during ref discovery.
+
+C: Start a queue, `c_pending`, ordered by commit time (popping newest
+   first).  Add all client refs.  When a commit is popped from
+   the queue its parents SHOULD be automatically inserted back.
+   Commits MUST only enter the queue once.
+
+'one compute step:'
+
+C: Send one `$GIT_URL/git-upload-pack` request:
+
+   C: 0032want <want #1>...............................
+   C: 0032want <want #2>...............................
+   ....
+   C: 0032have <common #1>.............................
+   C: 0032have <common #2>.............................
+   ....
+   C: 0032have <have #1>...............................
+   C: 0032have <have #2>...............................
+   ....
+   C: 0000
+
+The stream is organized into "commands", with each command
+appearing by itself in a pkt-line.  Within a command line,
+the text leading up to the first space is the command name,
+and the remainder of the line to the first LF is the value.
+Command lines are terminated with an LF as the last byte of
+the pkt-line value.
+
+Commands MUST appear in the following order, if they appear
+at all in the request stream:
+
+* "want"
+* "have"
+
+The stream is terminated by a pkt-line flush (`0000`).
+
+A single "want" or "have" command MUST have one hex formatted
+SHA-1 as its value.  Multiple SHA-1s MUST be sent by sending
+multiple commands.
+
+The `have` list is created by popping the first 32 commits
+from `c_pending`.  Less can be supplied if `c_pending` empties.
+
+If the client has sent 256 "have" commits and has not yet
+received one of those back from `s_common`, or the client has
+emptied `c_pending` it SHOULD include a "done" command to let
+the server know it won't proceed:
+
+   C: 0009done
+
+S: Parse the git-upload-pack request:
+
+Verify all objects in `want` are directly reachable from refs.
+
+The server MAY walk backwards through history or through
+the reflog to permit slightly stale requests.
+
+If no "want" objects are received, send an error:
+TODO: Define error if no "want" lines are requested.
+
+If any "want" object is not reachable, send an error:
+TODO: Define error if an invalid "want" is requested.
+
+Create an empty list, `s_common`.
+
+If "have" was sent:
+
+Loop through the objects in the order supplied by the client.
+
+For each object, if the server has the object reachable from
+a ref, add it to `s_common`.  If a commit is added to `s_common`,
+do not add any ancestors, even if they also appear in `have`.
+
+S: Send the git-upload-pack response:
+
+If the server has found a closed set of objects to pack or the
+request ends with "done", it replies with the pack.
+TODO: Document the pack based response
+
+   S: PACK...
+
+The returned stream is the side-band-64k protocol supported
+by the git-upload-pack service, and the pack is embedded into
+stream 1.  Progress messages from the server side MAY appear
+in stream 2.
+
+Here a "closed set of objects" is defined to have at least
+one path from every "want" to at least one "common" object.
+
+If the server needs more information, it replies with a
+status continue response:
+TODO: Document the non-pack response
+
+C: Parse the upload-pack response:
+   TODO: Document parsing response
+
+'Do another compute step.'
+
+
+Smart Service git-receive-pack
+------------------------------
+This service reads from the repository pointed to by `$GIT_URL`.
+
+Clients MUST first perform ref discovery with
+`$GIT_URL/info/refs?service=git-receive-pack`.

+Clients MUST NOT reuse or revalidate a cached response.
+Servers MUST include sufficient Cache-Control headers
+to prevent caching of the response.
+
+Servers SHOULD support all capabilities defined here.
+
+Clients MUST send at least one command in the request body.
+Within the command portion of the request body clients SHOULD send
+the id obtained through ref discovery as old_id.
+
+  update_request  =  command_list
+		     "PACK" <binary data>
+
+  command_list    =  PKT-LINE(command NUL cap_list LF)

+Git index format
+================
+
+== The Git index file has the following format
+
+  All binary numbers are in network byte order. Version 2 is described
+  here unless stated otherwise.
+
+   - A 12-byte header consisting of
+
+     4-byte signature:
+       The signature is { 'D', 'I', 'R', 'C' } (stands for "dircache")
+
+     4-byte version number:
+       The current supported versions are 2, 3 and 4.
+
+     32-bit number of index entries.
+
+   - A number of sorted index entries (see below).
+
+   - Extensions
+
+     Extensions are identified by signature. Optional extensions can
+     be ignored if Git does not understand them.
+
+     Git currently supports cached tree and resolve undo extensions.
+
+     4-byte extension signature. If the first byte is 'A'..'Z' the
+     extension is optional and can be ignored.
+
+     32-bit size of the extension

+      valid values in binary are 1000 (regular file), 1010 (symbolic link)

+
+    12-bit name length if the length is less than 0xFFF; otherwise 0xFFF
+    is stored in this field.

+  Entry path name (variable length) relative to top level directory
+    (without leading slash). '/' is used as path separator. The special
+    path components ".", ".." and ".git" (without quotes) are disallowed.
+    Trailing slash is also disallowed.
+
+    The exact encoding is undefined, but the '.' and '/' characters
+    are encoded in 7-bit ASCII and the encoding cannot contain a NUL
+    byte (iow, this is a UNIX pathname).
+
+  (Version 4) In version 4, the entry path name is prefix-compressed
+    relative to the path name for the previous entry (the very first
+    entry is encoded as if the path name for the previous entry is an
+    empty string).  At the beginning of an entry, an integer N in the
+    variable width encoding (the same encoding as the offset is encoded
+    for OFS_DELTA pack entries; see pack-format.txt) is stored, followed
+    by a NUL-terminated string S.  Removing N bytes from the end of the
+    path name for the previous entry, and replacing it with the string S
+    yields the path name for this entry.
+
+  1-8 nul bytes as necessary to pad the entry to a multiple of eight bytes
+  while keeping the name NUL-terminated.
+
+  (Version 4) In version 4, the padding after the pathname does not
+  exist.
+
+  Interpretation of index entries in split index mode is completely
+  different. See below for details.
+
+== Extensions
+
+=== Cached tree
+
+  Cached tree extension contains pre-computed hashes for trees that can
+  be derived from the index. It helps speed up tree object generation
+  from index for a new commit.
+
+  When a path is updated in index, the path must be invalidated and
+  removed from tree cache.
+
+  The signature for this extension is { 'T', 'R', 'E', 'E' }.
+
+  A series of entries fill the entire extension; each of which
+  consists of:
+
+  - NUL-terminated path component (relative to its parent directory);
+
+  - ASCII decimal number of entries in the index that is covered by the
+    tree this entry represents (entry_count);
+
+  - A space (ASCII 32);
+
+  - ASCII decimal number that represents the number of subtrees this
+    tree has;
+
+  - A newline (ASCII 10); and
+
+  - 160-bit object name for the object that would result from writing
+    this span of index as a tree.
+
+  An entry can be in an invalidated state and is represented by having
+  a negative number in the entry_count field. In this case, there is no
+  object name and the next entry starts immediately after the newline.
+  When writing an invalid entry, -1 should always be used as entry_count.
+
+  The entries are written out in the top-down, depth-first order.  The
+  first entry represents the root level of the repository, followed by the
+  first subtree---let's call this A---of the root level (with its name
+  relative to the root level), followed by the first subtree of A (with
+  its name relative to A), ...
+
+=== Resolve undo
+
+  A conflict is represented in the index as a set of higher stage entries.
+  When a conflict is resolved (e.g. with "git add path"), these higher
+  stage entries will be removed and a stage-0 entry with proper resolution
+  is added.
+
+  When these higher stage entries are removed, they are saved in the
+  resolve undo extension, so that conflicts can be recreated (e.g. with
+  "git checkout -m"), in case users want to redo a conflict resolution
+  from scratch.
+
+  The signature for this extension is { 'R', 'E', 'U', 'C' }.
+
+  A series of entries fill the entire extension; each of which
+  consists of:
+
+  - NUL-terminated pathname the entry describes (relative to the root of
+    the repository, i.e. full pathname);
+
+  - Three NUL-terminated ASCII octal numbers, entry mode of entries in
+    stage 1 to 3 (a missing stage is represented by "0" in this field);
+    and
+
+  - At most three 160-bit object names of the entry in stages from 1 to 3
+    (nothing is written for a missing stage).
+
+=== Split index
+
+  In split index mode, the majority of index entries could be stored
+  in a separate file. This extension records the changes to be made on
+  top of that to produce the final index.
+
+  The signature for this extension is { 'l', 'i', 'n', 'k' }.
+
+  The extension consists of:
+
+  - 160-bit SHA-1 of the shared index file. The shared index file path
+    is $GIT_DIR/sharedindex.<SHA-1>. If all 160 bits are zero, the
+    index does not require a shared index file.
+
+  - An ewah-encoded delete bitmap, each bit represents an entry in the
+    shared index. If a bit is set, its corresponding entry in the
+    shared index will be removed from the final index.  Note, because
+    a delete operation changes index entry positions, but we do need
+    original positions in replace phase, it's best to just mark
+    entries for removal, then do a mass deletion after replacement.
+
+  - An ewah-encoded replace bitmap, each bit represents an entry in
+    the shared index. If a bit is set, its corresponding entry in the
+    shared index will be replaced with an entry in this index
+    file. All replaced entries are stored in sorted order in this
+    index. The first "1" bit in the replace bitmap corresponds to the
+    first index entry, the second "1" bit to the second entry and so
+    on. Replaced entries may have empty path names to save space.
+
+  The remaining index entries after replaced ones will be added to the
+  final index. These added entries are also sorted by entry name then
+  stage.

+Packfile transfer protocols
+===========================
+
+Git supports transferring data in packfiles over the ssh://, git:// and
+file:// transports.  There exist two sets of protocols, one for pushing
+data from a client to a server and another for fetching data from a
+server to a client.  All three transports (ssh, git, file) use the same
+protocol to transfer data.
+
+The processes invoked in the canonical Git implementation are 'upload-pack'
+on the server side and 'fetch-pack' on the client side for fetching data;
+then 'receive-pack' on the server and 'send-pack' on the client for pushing
+data.  The protocol functions to have a server tell a client what is
+currently on the server, then for the two to negotiate the smallest amount
+of data to send in order to fully update one or the other.
+
+Transports
+----------
+There are three transports over which the packfile protocol is
+initiated.  The Git transport is a simple, unauthenticated server that
+takes the command (almost always 'upload-pack', though Git
+servers can be configured to be globally writable, in which 'receive-
+pack' initiation is also allowed) with which the client wishes to
+communicate and executes it and connects it to the requesting
+process.
+
+In the SSH transport, the client just runs the 'upload-pack'
+or 'receive-pack' process on the server over the SSH protocol and then
+communicates with that invoked process over the SSH connection.
+
+The file:// transport runs the 'upload-pack' or 'receive-pack'
+process locally and communicates with it over a pipe.
+
+Git Transport
+-------------
+
+The Git transport starts off by sending the command and repository
+on the wire using the pkt-line format, followed by a NUL byte and a
+hostname parameter, terminated by a NUL byte.
+
+   0032git-upload-pack /project.git\0host=myserver.com\0
+
+--
+   git-proto-request = request-command SP pathname NUL [ host-parameter NUL ]
+   request-command   = "git-upload-pack" / "git-receive-pack" /
+		       "git-upload-archive"   ; case sensitive
+   pathname          = *( %x01-ff ) ; exclude NUL
+   host-parameter    = "host=" hostname [ ":" port ]
+--
+
+Only host-parameter is allowed in the git-proto-request. Clients
+MUST NOT attempt to send additional parameters. It is used for the
+git-daemon name based virtual hosting.  See --interpolated-path
+option to git daemon, with the %H/%CH format characters.
+
+Basically what the Git client is doing to connect to an 'upload-pack'
+process on the server side over the Git protocol is this:
+
+   $ echo -e -n \
+     "0039git-upload-pack /schacon/gitbook.git\0host=example.com\0" |
+     nc -v example.com 9418
+
+If the server refuses the request for some reasons, it could abort
+gracefully with an error message.
+
+----
+  error-line     =  PKT-LINE("ERR" SP explanation-text)
+----
+
+
+SSH Transport
+-------------
+
+Initiating the upload-pack or receive-pack processes over SSH is
+executing the binary on the server via SSH remote execution.
+It is basically equivalent to running this:
+
+   $ ssh git.example.com "git-upload-pack '/project.git'"
+
+For a server to support Git pushing and pulling for a given user over
+SSH, that user needs to be able to execute one or both of those
+commands via the SSH shell that they are provided on login.  On some
+systems, that shell access is limited to only being able to run those
+two commands, or even just one of them.
+
+In an ssh:// format URI, it's absolute in the URI, so the '/' after
+the host name (or port number) is sent as an argument, which is then
+read by the remote git-upload-pack exactly as is, so it's effectively
+an absolute path in the remote filesystem.
+
+       git clone ssh://user@example.com/project.git
+		    |
+		    v
+    ssh user@example.com "git-upload-pack '/project.git'"
+
+In a "user@host:path" format URI, its relative to the user's home
+directory, because the Git client will run:
+
+     git clone user@example.com:project.git
+		    |
+		    v
+  ssh user@example.com "git-upload-pack 'project.git'"
+
+The exception is if a '~' is used, in which case
+we execute it without the leading '/'.
+
+      ssh://user@example.com/~alice/project.git,
+		     |
+		     v
+   ssh user@example.com "git-upload-pack '~alice/project.git'"
+
+A few things to remember here:
+
+- The "command name" is spelled with dash (e.g. git-upload-pack), but
+  this can be overridden by the client;
+
+- The repository path is always quoted with single quotes.
+
+Fetching Data From a Server
+---------------------------
+
+When one Git repository wants to get data that a second repository
+has, the first can 'fetch' from the second.  This operation determines
+what data the server has that the client does not then streams that
+data down to the client in packfile format.
+
+
+Reference Discovery
+-------------------
+
+When the client initially connects the server will immediately respond
+with a listing of each reference it has (all branches and tags) along
+with the object name that each reference currently points to.
+
+   $ echo -e -n "0039git-upload-pack /schacon/gitbook.git\0host=example.com\0" |
+      nc -v example.com 9418
+   00887217a7c7e582c46cec22a130adf4b9d7d950fba0 HEAD\0multi_ack thin-pack

+   0000
+
+Server SHOULD terminate each non-flush line using LF ("\n") terminator;
+client MUST NOT complain if there is no terminator.
+
+The returned response is a pkt-line stream describing each ref and
+its current value.  The stream MUST be sorted by name according to
+the C locale ordering.
+
+If HEAD is a valid ref, HEAD MUST appear as the first advertised
+ref.  If HEAD is not a valid ref, HEAD MUST NOT appear in the
+advertisement list at all, but other refs may still appear.
+
+The stream MUST include capability declarations behind a NUL on the
+first ref. The peeled value of a ref (that is "ref^{}") MUST be
+immediately after the ref itself, if presented. A conforming server

+
+Packfile Negotiation
+--------------------
+After reference and capabilities discovery, the client can decide to
+terminate the connection by sending a flush-pkt, telling the server it can
+now gracefully terminate, and disconnect, when it does not need any pack
+data. This can happen with the ls-remote command, and also can happen when
+the client already is up-to-date.
+
+Otherwise, it enters the negotiation phase, where the client and
+server determine what the minimal packfile necessary for transport is,
+by telling the server what objects it wants, its shallow objects
+(if any), and the maximum commit depth it wants (if any).  The client
+will also send a list of the capabilities it wants to be in effect,
+out of what the server said it could do with the first 'want' line.
+
+----
+  upload-request    =  want-list
+		       *shallow-line
+		       *1depth-request
+		       flush-pkt
+
+  want-list         =  first-want
+		       *additional-want
+
+  shallow-line      =  PKT-LINE("shallow" SP obj-id)
+
+  depth-request     =  PKT-LINE("deepen" SP depth)
+
+  first-want        =  PKT-LINE("want" SP obj-id SP capability-list LF)
+  additional-want   =  PKT-LINE("want" SP obj-id LF)
+
+  depth             =  1*DIGIT
+----
+
+Clients MUST send all the obj-ids it wants from the reference
+discovery phase as 'want' lines. Clients MUST send at least one
+'want' command in the request body. Clients MUST NOT mention an
+obj-id in a 'want' command which did not appear in the response
+obtained through ref discovery.
+
+The client MUST write all obj-ids which it only has shallow copies
+of (meaning that it does not have the parents of a commit) as
+'shallow' lines so that the server is aware of the limitations of
+the client's history.
+
+The client now sends the maximum commit history depth it wants for
+this transaction, which is the number of commits it wants from the
+tip of the history, if any, as a 'deepen' line.  A depth of 0 is the
+same as not making a depth request. The client does not want to receive
+any commits beyond this depth, nor does it want objects needed only to
+complete those commits. Commits whose parents are not received as a
+result are defined as shallow and marked as such in the server. This
+information is sent back to the client in the next step.
+
+Once all the 'want's and 'shallow's (and optional 'deepen') are
+transferred, clients MUST send a flush-pkt, to tell the server side
+that it is done sending the list.
+
+Otherwise, if the client sent a positive depth request, the server
+will determine which commits will and will not be shallow and
+send this information to the client. If the client did not request
+a positive depth, this step is skipped.
+
+----
+  shallow-update   =  *shallow-line
+		      *unshallow-line
+		      flush-pkt
+
+  shallow-line     =  PKT-LINE("shallow" SP obj-id)
+
+  unshallow-line   =  PKT-LINE("unshallow" SP obj-id)
+----
+
+If the client has requested a positive depth, the server will compute
+the set of commits which are no deeper than the desired depth. The set
+of commits start at the client's wants.
+
+The server writes 'shallow' lines for each
+commit whose parents will not be sent as a result. The server writes
+an 'unshallow' line for each commit which the client has indicated is
+shallow, but is no longer shallow at the currently requested depth
+(that is, its parents will now be sent). The server MUST NOT mark
+as unshallow anything which the client has not indicated was shallow.
+
+Now the client will send a list of the obj-ids it has using 'have'
+lines, so the server can make a packfile that only contains the objects
+that the client needs. In multi_ack mode, the canonical implementation
+will send up to 32 of these at a time, then will send a flush-pkt. The
+canonical implementation will skip ahead and send the next 32 immediately,
+so that there is always a block of 32 "in-flight on the wire" at a time.
+
+----
+  upload-haves      =  have-list
+		       compute-end
+
+  have-list         =  *have-line
+  have-line         =  PKT-LINE("have" SP obj-id LF)
+  compute-end       =  flush-pkt / PKT-LINE("done")
+----
+
+If the server reads 'have' lines, it then will respond by ACKing any
+of the obj-ids the client said it had that the server also has. The
+server will ACK obj-ids differently depending on which ack mode is
+chosen by the client.
+
+In multi_ack mode:
+
+  * the server will respond with 'ACK obj-id continue' for any common
+    commits.
+
+  * once the server has found an acceptable common base commit and is
+    ready to make a packfile, it will blindly ACK all 'have' obj-ids
+    back to the client.
+
+  * the server will then send a 'NACK' and then wait for another response
+    from the client - either a 'done' or another list of 'have' lines.
+
+In multi_ack_detailed mode:
+
+  * the server will differentiate the ACKs where it is signaling
+    that it is ready to send data with 'ACK obj-id ready' lines, and
+    signals the identified common commits with 'ACK obj-id common' lines.
+
+Without either multi_ack or multi_ack_detailed:
+
+ * upload-pack sends "ACK obj-id" on the first common object it finds.
+   After that it says nothing until the client gives it a "done".
+
+ * upload-pack sends "NAK" on a flush-pkt if no common object
+   has been found yet.  If one has been found, and thus an ACK
+   was already sent, it's silent on the flush-pkt.
+
+After the client has gotten enough ACK responses that it can determine
+that the server has enough information to send an efficient packfile
+(in the canonical implementation, this is determined when it has received
+enough ACKs that it can color everything left in the --date-order queue
+as common with the server, or the --date-order queue is empty), or the
+client determines that it wants to give up (in the canonical implementation,
+this is determined when the client sends 256 'have' lines without getting
+any of them ACKed by the server - meaning there is nothing in common and
+the server should just send all of its objects), then the client will send
+a 'done' command.  The 'done' command signals to the server that the client
+is ready to receive its packfile data.
+
+However, the 256 limit *only* turns on in the canonical client
+implementation if we have received at least one "ACK %s continue"
+during a prior round.  This helps to ensure that at least one common
+ancestor is found before we give up entirely.
+
+Once the 'done' line is read from the client, the server will either
+send a final 'ACK obj-id' or it will send a 'NAK'. 'obj-id' is the object
+name of the last commit determined to be common. The server only sends
+ACK after 'done' if there is at least one common base and multi_ack or
+multi_ack_detailed is enabled. The server always sends NAK after 'done'
+if there is no common base found.
+
+Then the server will start sending its packfile data.

+   S: [PACKFILE]
+----
+
+
+Packfile Data
+-------------
+
+Now that the client and server have finished negotiation about what
+the minimal amount of data that needs to be sent to the client is, the server
+will construct and send the required data in packfile format.
+
+See pack-format.txt for what the packfile itself actually looks like.
+
+If 'side-band' or 'side-band-64k' capabilities have been specified by
+the client, the server will send the packfile data multiplexed.
+
+Each packet starting with the packet-line length of the amount of data
+that follows, followed by a single byte specifying the sideband the
+following data is coming in on.
+
+In 'side-band' mode, it will send up to 999 data bytes plus 1 control
+code, for a total of up to 1000 bytes in a pkt-line.  In 'side-band-64k'
+mode it will send up to 65519 data bytes plus 1 control code, for a
+total of up to 65520 bytes in a pkt-line.
+
+The sideband byte will be a '1', '2' or a '3'. Sideband '1' will contain
+packfile data, sideband '2' will be used for progress information that the
+client will generally print to stderr and sideband '3' is used for error
+information.
+
+If no 'side-band' capability was specified, the server will stream the
+entire packfile without multiplexing.
+
+
+Pushing Data To a Server
+------------------------
+
+Pushing data to a server will invoke the 'receive-pack' process on the
+server, which will allow the client to tell it which references it should
+update and then send all the data the server will need for those new
+references to be complete.  Once all the data is received and validated,
+the server will then update its references to what the client specified.
+
+Authentication
+--------------
+
+The protocol itself contains no authentication mechanisms.  That is to be
+handled by the transport, such as SSH, before the 'receive-pack' process is
+invoked.  If 'receive-pack' is configured over the Git transport, those
+repositories will be writable by anyone who can access that port (9418) as
+that transport is unauthenticated.
+
+Reference Discovery
+-------------------
+
+The reference discovery phase is done nearly the same way as it is in the
+fetching protocol. Each reference obj-id and name on the server is sent
+in packet-line format to the client, followed by a flush-pkt.  The only
+real difference is that the capability listing is different - the only
+possible values are 'report-status', 'delete-refs' and 'ofs-delta'.
+
+Reference Update Request and Packfile Transfer
+----------------------------------------------
+
+Once the client knows what references the server is at, it can send a
+list of reference update requests.  For each reference on the server
+that it wants to update, it sends a line listing the obj-id currently on
+the server, the obj-id the client would like to update it to and the name
+of the reference.
+
+This list is followed by a flush-pkt and then the packfile that should
+contain all the objects that the server will need to complete the new
+references.
+
+----
+  update-request    =  *shallow ( command-list | push-cert ) [pack-file]
+
+  shallow           =  PKT-LINE("shallow" SP obj-id LF)
+
+  command-list      =  PKT-LINE(command NUL capability-list LF)
+		       *PKT-LINE(command LF)
+		       flush-pkt
+
+  command           =  create / delete / update
+  create            =  zero-id SP new-id  SP name
+  delete            =  old-id  SP zero-id SP name
+  update            =  old-id  SP new-id  SP name
+
+  old-id            =  obj-id
+  new-id            =  obj-id
+
+  push-cert         = PKT-LINE("push-cert" NUL capability-list LF)
+		      PKT-LINE("certificate version 0.1" LF)
+		      PKT-LINE("pusher" SP ident LF)
+		      PKT-LINE("pushee" SP url LF)
+		      PKT-LINE("nonce" SP nonce LF)
+		      PKT-LINE(LF)
+		      *PKT-LINE(command LF)
+		      *PKT-LINE(gpg-signature-lines LF)
+		      PKT-LINE("push-cert-end" LF)
+
+  pack-file         = "PACK" 28*(OCTET)
+----
+
+If the receiving end does not support delete-refs, the sending end MUST
+NOT ask for delete command.
+
+If the receiving end does not support push-cert, the sending end
+MUST NOT send a push-cert command.  When a push-cert command is
+sent, command-list MUST NOT be sent; the commands recorded in the
+push certificate is used instead.
+
+The pack-file MUST NOT be sent if the only command used is 'delete'.
+
+A pack-file MUST be sent if either create or update command is used,
+even if the server already has all the necessary objects.  In this
+case the client MUST send an empty pack-file.   The only time this
+is likely to happen is if the client is creating
+a new branch or a tag that points to an existing obj-id.
+
+The server will receive the packfile, unpack it, then validate each
+reference that is being updated that it hasn't changed while the request
+was being processed (the obj-id is still the same as the old-id), and
+it will run any update hooks to make sure that the update is acceptable.
+If all of that is fine, the server will then update the references.
+
+Push Certificate
+----------------
+
+A push certificate begins with a set of header lines.  After the
+header and an empty line, the protocol commands follow, one per
+line.
+
+Currently, the following header fields are defined:
+
+`pusher` ident::
+	Identify the GPG key in "Human Readable Name <email@address>"
+	format.
+
+`pushee` url::
+	The repository URL (anonymized, if the URL contains
+	authentication material) the user who ran `git push`
+	intended to push into.
+
+`nonce` nonce::
+	The 'nonce' string the receiving repository asked the
+	pushing user to include in the certificate, to prevent
+	replay attacks.
+
+The GPG signature lines are a detached signature for the contents
+recorded in the push certificate before the signature block begins.
+The detached signature is used to certify that the commands were
+given by the pusher, who must be the signer.
+
+Report Status
+-------------
+
+After receiving the pack data from the sender, the receiver sends a
+report if 'report-status' capability is in effect.
+It is a short listing of what happened in that update.  It will first
+list the status of the packfile unpacking as either 'unpack ok' or
+'unpack [error]'.  Then it will list the status for each of the references
+that it tried to update.  Each line is either 'ok [refname]' if the
+update was successful, or 'ng [refname] [error]' if the update was not.
+
+----
+  report-status     = unpack-status
+		      1*(command-status)
+		      flush-pkt
+
+  unpack-status     = PKT-LINE("unpack" SP unpack-result LF)
+  unpack-result     = "ok" / error-msg
+
+  command-status    = command-ok / command-fail
+  command-ok        = PKT-LINE("ok" SP refname LF)
+  command-fail      = PKT-LINE("ng" SP refname SP error-msg LF)
+
+  error-msg         = 1*(OCTECT) ; where not "ok"
+----
+
+Updates can be unsuccessful for a number of reasons.  The reference can have
+changed since the reference discovery phase was originally sent, meaning
+someone pushed in the meantime.  The reference being pushed could be a
+non-fast-forward reference and the update hooks or configuration could be
+set to not allow that, etc.  Also, some references can be updated while others
+can be rejected.
+
+An example client/server communication might look like this:

+Git Protocol Capabilities
+=========================
+
+Servers SHOULD support all capabilities defined in this document.
+
+On the very first line of the initial server response of either
+receive-pack and upload-pack the first reference is followed by
+a NUL byte and then a list of space delimited server capabilities.
+These allow the server to declare what it can and cannot support
+to the client.
+
+Client will then send a space separated list of capabilities it wants
+to be in effect. The client MUST NOT ask for capabilities the server
+did not say it supports.
+
+Server MUST diagnose and abort if capabilities it does not understand
+was sent.  Server MUST NOT ignore capabilities that client requested
+and server advertised.  As a consequence of these rules, server MUST
+NOT advertise capabilities it does not understand.
+
+The 'report-status', 'delete-refs', 'quiet', and 'push-cert' capabilities
+are sent and recognized by the receive-pack (push to server) process.
+
+The 'ofs-delta' and 'side-band-64k' capabilities are sent and recognized
+by both upload-pack and receive-pack protocols.  The 'agent' capability
+may optionally be sent in both protocols.
+
+All other capabilities are only recognized by the upload-pack (fetch
+from server) process.
+
+multi_ack
+---------
+
+The 'multi_ack' capability allows the server to return "ACK obj-id
+continue" as soon as it finds a commit that it can use as a common
+base, between the client's wants and the client's have set.
+
+By sending this early, the server can potentially head off the client
+from walking any further down that particular branch of the client's
+repository history.  The client may still need to walk down other
+branches, sending have lines for those, until the server has a
+complete cut across the DAG, or the client has said "done".
+
+Without multi_ack, a client sends have lines in --date-order until
+the server has found a common base.  That means the client will send
+have lines that are already known by the server to be common, because
+they overlap in time with another branch that the server hasn't found
+a common base on yet.
+
+For example suppose the client has commits in caps that the server
+doesn't and the server has commits in lower case that the client
+doesn't, as in the following diagram:
+
+       +---- u ---------------------- x
+      /              +----- y
+     /              /
+    a -- b -- c -- d -- E -- F
+       \
+	+--- Q -- R -- S
+
+If the client wants x,y and starts out by saying have F,S, the server
+doesn't know what F,S is.  Eventually the client says "have d" and
+the server sends "ACK d continue" to let the client know to stop
+walking down that line (so don't send c-b-a), but it's not done yet,
+it needs a base for x. The client keeps going with S-R-Q, until a
+gets reached, at which point the server has a clear base and it all
+ends.
+
+Without multi_ack the client would have sent that c-b-a chain anyway,
+interleaved with S-R-Q.
+
+multi_ack_detailed
+------------------
+This is an extension of multi_ack that permits client to better
+understand the server's in-memory state. See pack-protocol.txt,
+section "Packfile Negotiation" for more information.
+
+no-done
+-------
+This capability should only be used with the smart HTTP protocol. If
+multi_ack_detailed and no-done are both present, then the sender is
+free to immediately send a pack following its first "ACK obj-id ready"
+message.
+
+Without no-done in the smart HTTP protocol, the server session would
+end and the client has to make another trip to send "done" before
+the server can send the pack. no-done removes the last round and
+thus slightly reduces latency.
+
+thin-pack
+---------
+
+A thin pack is one with deltas which reference base objects not
+contained within the pack (but are known to exist at the receiving
+end). This can reduce the network traffic significantly, but it
+requires the receiving end to know how to "thicken" these packs by
+adding the missing bases to the pack.
+
+The upload-pack server advertises 'thin-pack' when it can generate
+and send a thin pack. A client requests the 'thin-pack' capability
+when it understands how to "thicken" it, notifying the server that
+it can receive such a pack. A client MUST NOT request the
+'thin-pack' capability if it cannot turn a thin pack into a
+self-contained pack.
+
+Receive-pack, on the other hand, is assumed by default to be able to
+handle thin packs, but can ask the client not to use the feature by
+advertising the 'no-thin' capability. A client MUST NOT send a thin
+pack if the server advertises the 'no-thin' capability.
+
+The reasons for this asymmetry are historical. The receive-pack
+program did not exist until after the invention of thin packs, so
+historically the reference implementation of receive-pack always
+understood thin packs. Adding 'no-thin' later allowed receive-pack
+to disable the feature in a backwards-compatible manner.
+
+
+side-band, side-band-64k
+------------------------
+
+This capability means that server can send, and client understand multiplexed
+progress reports and error info interleaved with the packfile itself.
+
+These two options are mutually exclusive. A modern client always
+favors 'side-band-64k'.
+
+Either mode indicates that the packfile data will be streamed broken
+up into packets of up to either 1000 bytes in the case of 'side_band',
+or 65520 bytes in the case of 'side_band_64k'. Each packet is made up
+of a leading 4-byte pkt-line length of how much data is in the packet,
+followed by a 1-byte stream code, followed by the actual data.
+
+The stream code can be one of:
+
+ 1 - pack data
+ 2 - progress messages
+ 3 - fatal error message just before stream aborts
+
+The "side-band-64k" capability came about as a way for newer clients
+that can handle much larger packets to request packets that are
+actually crammed nearly full, while maintaining backward compatibility
+for the older clients.
+
+Further, with side-band and its up to 1000-byte messages, it's actually
+999 bytes of payload and 1 byte for the stream code. With side-band-64k,
+same deal, you have up to 65519 bytes of data and 1 byte for the stream
+code.
+
+The client MUST send only maximum of one of "side-band" and "side-
+band-64k".  Server MUST diagnose it as an error if client requests
+both.
+
+ofs-delta
+---------
+
+Server can send, and client understand PACKv2 with delta referring to
+its base by position in pack rather than by an obj-id.  That is, they can
+send/read OBJ_OFS_DELTA (aka type 6) in a packfile.
+
+agent
+-----
+
+The server may optionally send a capability of the form `agent=X` to
+notify the client that the server is running version `X`. The client may
+optionally return its own agent string by responding with an `agent=Y`
+capability (but it MUST NOT do so if the server did not mention the
+agent capability). The `X` and `Y` strings may contain any printable
+ASCII characters except space (i.e., the byte range 32 < x < 127), and
+are typically of the form "package/version" (e.g., "git/1.8.3.1"). The
+agent strings are purely informative for statistics and debugging
+purposes, and MUST NOT be used to programmatically assume the presence
+or absence of particular features.
+
+shallow
+-------
+
+This capability adds "deepen", "shallow" and "unshallow" commands to
+the  fetch-pack/upload-pack protocol so clients can request shallow
+clones.
+
+no-progress
+-----------
+
+The client was started with "git clone -q" or something, and doesn't
+want that side band 2.  Basically the client just says "I do not
+wish to receive stream 2 on sideband, so do not send it to me, and if
+you did, I will drop it on the floor anyway".  However, the sideband
+channel 3 is still used for error responses.
+
+include-tag
+-----------
+
+The 'include-tag' capability is about sending annotated tags if we are
+sending objects they point to.  If we pack an object to the client, and
+a tag object points exactly at that object, we pack the tag object too.
+In general this allows a client to get all new annotated tags when it
+fetches a branch, in a single network connection.
+
+Clients MAY always send include-tag, hardcoding it into a request when
+the server advertises this capability. The decision for a client to
+request include-tag only has to do with the client's desires for tag
+data, whether or not a server had advertised objects in the
+refs/tags/* namespace.
+
+Servers MUST pack the tags if their referrant is packed and the client
+has requested include-tags.
+
+Clients MUST be prepared for the case where a server has ignored
+include-tag and has not actually sent tags in the pack.  In such
+cases the client SHOULD issue a subsequent fetch to acquire the tags
+that include-tag would have otherwise given the client.
+
+The server SHOULD send include-tag, if it supports it, regardless
+of whether or not there are tags available.
+
+report-status
+-------------
+
+The receive-pack process can receive a 'report-status' capability,
+which tells it that the client wants a report of what happened after
+a packfile upload and reference update.  If the pushing client requests
+this capability, after unpacking and updating references the server
+will respond with whether the packfile unpacked successfully and if
+each reference was updated successfully.  If any of those were not
+successful, it will send back an error message.  See pack-protocol.txt
+for example messages.
+
+delete-refs
+-----------
+
+If the server sends back the 'delete-refs' capability, it means that
+it is capable of accepting a zero-id value as the target
+value of a reference update.  It is not sent back by the client, it
+simply informs the client that it can be sent zero-id values
+to delete references.
+
+quiet
+-----
+
+If the receive-pack server advertises the 'quiet' capability, it is
+capable of silencing human-readable progress output which otherwise may
+be shown when processing the received pack. A send-pack client should
+respond with the 'quiet' capability to suppress server-side progress
+reporting if the local progress reporting is also being suppressed
+(e.g., via `push -q`, or if stderr does not go to a tty).
+
+allow-tip-sha1-in-want
+----------------------
+
+If the upload-pack server advertises this capability, fetch-pack may
+send "want" lines with SHA-1s that exist at the server but are not
+advertised by upload-pack.
+
+push-cert=<nonce>
+-----------------
+
+The receive-pack server that advertises this capability is willing
+to accept a signed push certificate, and asks the <nonce> to be
+included in the push certificate.  A send-pack client MUST NOT
+send a push-cert packet unless the receive-pack server advertises
+this capability.

+Documentation Common to Pack and Http Protocols
+===============================================
+
+ABNF Notation
+-------------
+
+ABNF notation as described by RFC 5234 is used within the protocol documents,
+except the following replacement core rules are used:
+----
+  HEXDIG    =  DIGIT / "a" / "b" / "c" / "d" / "e" / "f"
+----
+
+We also define the following common rules:
+----
+  NUL       =  %x00
+  zero-id   =  40*"0"
+  obj-id    =  40*(HEXDIGIT)
+
+  refname  =  "HEAD"
+  refname /=  "refs/" <see discussion below>
+----
+
+A refname is a hierarchical octet string beginning with "refs/" and
+not violating the 'git-check-ref-format' command's validation rules.
+More specifically, they:
+
+. They can include slash `/` for hierarchical (directory)
+  grouping, but no slash-separated component can begin with a
+  dot `.`.
+
+. They must contain at least one `/`. This enforces the presence of a
+  category like `heads/`, `tags/` etc. but the actual names are not
+  restricted.
+
+. They cannot have two consecutive dots `..` anywhere.
+
+. They cannot have ASCII control characters (i.e. bytes whose
+  values are lower than \040, or \177 `DEL`), space, tilde `~`,
+  caret `^`, colon `:`, question-mark `?`, asterisk `*`,
+  or open bracket `[` anywhere.
+
+. They cannot end with a slash `/` or a dot `.`.
+
+. They cannot end with the sequence `.lock`.
+
+. They cannot contain a sequence `@{`.
+
+. They cannot contain a `\\`.
+
+
+pkt-line Format
+---------------
+
+Much (but not all) of the payload is described around pkt-lines.
+
+A pkt-line is a variable length binary string.  The first four bytes
+of the line, the pkt-len, indicates the total length of the line,
+in hexadecimal.  The pkt-len includes the 4 bytes used to contain
+the length's hexadecimal representation.
+
+A pkt-line MAY contain binary data, so implementors MUST ensure
+pkt-line parsing/formatting routines are 8-bit clean.
+
+A non-binary line SHOULD BE terminated by an LF, which if present
+MUST be included in the total length.
+
+The maximum length of a pkt-line's data component is 65520 bytes.
+Implementations MUST NOT send pkt-line whose length exceeds 65524
+(65520 bytes of payload + 4 bytes of length data).
+
+Implementations SHOULD NOT send an empty pkt-line ("0004").
+
+A pkt-line with a length field of 0 ("0000"), called a flush-pkt,
+is a special case and MUST be handled differently than an empty
+pkt-line ("0004").
+
+----
+  pkt-line     =  data-pkt / flush-pkt
+
+  data-pkt     =  pkt-len pkt-payload
+  pkt-len      =  4*(HEXDIG)
+  pkt-payload  =  (pkt-len - 4)*(OCTET)
+
+  flush-pkt    = "0000"
+----
+
+Examples (as C-style strings):

+  "0006a\n"         "a\n"

 GIT URLS[[URLS]]
 ----------------
 
-One of the following notations can be used
-to name the remote repository:
+In general, URLs contain information about the transport protocol, the
+address of the remote server, and the path to the repository.
+Depending on the transport protocol, some of this information may be
+absent.
+
+Git supports ssh, git, http, and https protocols (in addition, ftp,
+and ftps can be used for fetching and rsync can be used for fetching
+and pushing, but these are inefficient and deprecated; do not use
+them).
+
+The native transport (i.e. git:// URL) does no authentication and
+should be used with caution on unsecured networks.
+
+The following syntaxes may be used with them:
 
-===============================================================
-- rsync://host.xz/path/to/repo.git/
-- http://host.xz{startsb}:port{endsb}/path/to/repo.git/
-- https://host.xz{startsb}:port{endsb}/path/to/repo.git/
-- git://host.xz{startsb}:port{endsb}/path/to/repo.git/
-- git://host.xz{startsb}:port{endsb}/~user/path/to/repo.git/

-- ssh://{startsb}user@{endsb}host.xz/~user/path/to/repo.git/
-- ssh://{startsb}user@{endsb}host.xz/~/path/to/repo.git
-===============================================================
-
-SSH is the default transport protocol over the network.  You can
-optionally specify which user to log-in as, and an alternate,
-scp-like syntax is also supported.  Both syntaxes support
-username expansion, as does the native git protocol, but
-only the former supports port specification. The following
-three are identical to the last three above, respectively:
-
-===============================================================
-- {startsb}user@{endsb}host.xz:/path/to/repo.git/
-- {startsb}user@{endsb}host.xz:~user/path/to/repo.git/
-- {startsb}user@{endsb}host.xz:path/to/repo.git
-===============================================================
-
-To sync with a local directory, you can use:
-

+- git://host.xz{startsb}:port{endsb}/path/to/repo.git/
+- http{startsb}s{endsb}://host.xz{startsb}:port{endsb}/path/to/repo.git/
+- ftp{startsb}s{endsb}://host.xz{startsb}:port{endsb}/path/to/repo.git/
+- rsync://host.xz/path/to/repo.git/
+
+An alternative scp-like syntax may also be used with the ssh protocol:
+
+- {startsb}user@{endsb}host.xz:path/to/repo.git/
+
+This syntax is only recognized if there are no slashes before the
+first colon. This helps differentiate a local path that contains a
+colon. For example the local path `foo:bar` could be specified as an
+absolute path or `./foo:bar` to avoid being misinterpreted as an ssh
+url.
+
+The ssh and git protocols additionally support ~username expansion:
+
+- ssh://{startsb}user@{endsb}host.xz{startsb}:port{endsb}/~{startsb}user{endsb}/path/to/repo.git/
+- git://host.xz{startsb}:port{endsb}/~{startsb}user{endsb}/path/to/repo.git/
+- {startsb}user@{endsb}host.xz:/~{startsb}user{endsb}/path/to/repo.git/
+
+For local repositories, also supported by Git natively, the following
+syntaxes may be used:

+
+As explained in the comments, you can reorder commits, squash them
+together, edit commit messages, etc. by editing the list.  Once you
+are satisfied, save the list and close your editor, and the rebase
+will begin.
+
+The rebase will stop where `pick` has been replaced with `edit` or
+when a step in the list fails to mechanically resolve conflicts and

+you can continue with `git rebase --continue`.  If you decide that

+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+### Target-specific flags and dependencies
+
+# The generic compilation pattern rule and automatically
+# computed header dependencies (falling back to a dependency on
+# LIB_H) are enough to describe how most targets should be built,
+# but some targets are special enough to need something a little
+# different.
+#
+# - When a source file "foo.c" #includes a generated header file,
+#   we need to list that dependency for the "foo.o" target.
+#
+#   We also list it from other targets that are built from foo.c
+#   like "foo.sp" and "foo.s", even though that is easy to forget
+#   to do because the generated header is already present around
+#   after a regular build attempt.
+#
+# - Some code depends on configuration kept in makefile
+#   variables. The target-specific variable EXTRA_CPPFLAGS can
+#   be used to convey that information to the C preprocessor
+#   using -D options.
+#
+#   The "foo.o" target should have a corresponding dependency on
+#   a file that changes when the value of the makefile variable
+#   changes.  For example, targets making use of the
+#   $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
+#
+#   Technically the ".sp" and ".s" targets do not need this
+#   dependency because they are force-built, but they get the
+#   same dependency for consistency. This way, you do not have to
+#   know how each target is implemented. And it means the
+#   dependencies here will not need to change if the force-build
+#   details change some day.

- * Check-out files from the "current cache directory"
- *
- * Copyright (C) 2005 Linus Torvalds
- *
- * Careful: order of argument flags does matter. For example,
- *
- *	git checkout-index -a -f file.c
- *
- * Will first check out all files listed in the cache (but not
- * overwrite any old ones), and then force-checkout "file.c" a
- * second time (ie that one _will_ overwrite any old contents
- * with the same filename).
- *
- * Also, just doing "git checkout-index" does nothing. You probably
- * meant "git checkout-index -a". And if you want to force it, you
- * want "git checkout-index -f -a".
- *
- * Intuitiveness is not the goal here. Repeatability is. The
- * reason for the "no arguments means no work" thing is that
- * from scripts you are supposed to be able to do things like
- *
- *	find . -name '*.h' -print0 | xargs -0 git checkout-index -f --
- *
- * or:
- *
- *	find . -name '*.h' -print0 | git checkout-index -f -z --stdin
- *
- * which will force all existing *.h files to be replaced with
- * their cached copies. If an empty command line implied "all",
- * then this would force-refresh everything in the cache, which
- * was not the point.
- *
- * Oh, and the "--" is just a good idea when you know the rest
- * will be filenames. Just so that you wouldn't have a filename
- * of "-a" causing problems (not possible in the above example,
- * but get used to it in scripting!).

+#define COMMIT_SLAB_H
+
+/*
+ * define_commit_slab(slabname, elemtype) creates boilerplate code to define
+ * a new struct (struct slabname) that is used to associate a piece of data
+ * of elemtype to commits, and a few functions to use that struct.
+ *
+ * After including this header file, using:
+ *
+ * define_commit_slab(indegee, int);
+ *
+ * will let you call the following functions:
+ *
+ * - int *indegree_at(struct indegree *, struct commit *);
+ *
+ *   This function locates the data associated with the given commit in
+ *   the indegree slab, and returns the pointer to it.
+ *
+ * - void init_indegree(struct indegree *);
+ *   void init_indegree_with_stride(struct indegree *, int);
+ *
+ *   Initializes the indegree slab that associates an array of integers
+ *   to each commit. 'stride' specifies how big each array is.  The slab
+ *   that is initialized by the variant without "_with_stride" associates
+ *   each commit with an array of one integer.
+ *
+ * - void clear_indegree(struct indegree *);
+ *
+ *   Empties the slab.  The slab can be reused with the same stride
+ *   without calling init_indegree() again or can be reconfigured to a
+ *   different stride by calling init_indegree_with_stride().
+ *
+ *   Call this function before the slab falls out of scope to avoid
+ *   leaking memory.

+/* Summary:
+
+All the apparent functions defined here are macros. The idea
+is that you would use these pre-tested macros to solve a
+very specific set of problems, and they would run fast.
+Caution: no side-effects in arguments please!! They may be
+evaluated MANY times!!
+
+These macros operate a stack of objects.  Each object starts life
+small, and may grow to maturity.  (Consider building a word syllable
+by syllable.)  An object can move while it is growing.  Once it has
+been "finished" it never changes address again.  So the "top of the
+stack" is typically an immature growing object, while the rest of the
+stack is of mature, fixed size and fixed address objects.
+
+These routines grab large chunks of memory, using a function you
+supply, called `obstack_chunk_alloc'.  On occasion, they free chunks,
+by calling `obstack_chunk_free'.  You must define them and declare
+them before using any obstack macros.
+
+Each independent stack is represented by a `struct obstack'.
+Each of the obstack macros expects a pointer to such a structure
+as the first argument.
+
+One motivation for this package is the problem of growing char strings
+in symbol tables.  Unless you are "fascist pig with a read-only mind"
+--Gosper's immortal quote from HAKMEM item 154, out of context--you
+would not like to put any arbitrary upper limit on the length of your
+symbols.
+
+In practice this often means you will build many short symbols and a
+few long symbols.  At the time you are reading a symbol you don't know
+how long it is.  One traditional method is to read a symbol into a
+buffer, realloc()ating the buffer every time you try to read a symbol
+that is longer than the buffer.  This is beaut, but you still will
+want to copy the symbol from the buffer to a more permanent
+symbol-table entry say about half the time.
+
+With obstacks, you can work differently.  Use one obstack for all symbol
+names.  As you read a symbol, grow the name in the obstack gradually.
+When the name is complete, finalize it.  Then, if the symbol exists already,
+free the newly read name.
+
+The way we do this is to take a large chunk, allocating memory from
+low addresses.  When you want to build a symbol in the chunk you just
+add chars above the current "high water mark" in the chunk.  When you
+have finished adding chars, because you got to the end of the symbol,
+you know how long the chars are, and you can create a new object.
+Mostly the chars will not burst over the highest address of the chunk,
+because you would typically expect a chunk to be (say) 100 times as
+long as an average object.
+
+In case that isn't clear, when we have enough chars to make up
+the object, THEY ARE ALREADY CONTIGUOUS IN THE CHUNK (guaranteed)
+so we just point to it where it lies.  No moving of chars is
+needed and this is the second win: potentially long strings need
+never be explicitly shuffled. Once an object is formed, it does not
+change its address during its lifetime.
+
+When the chars burst over a chunk boundary, we allocate a larger
+chunk, and then copy the partly formed object from the end of the old
+chunk to the beginning of the new larger chunk.  We then carry on
+accreting characters to the end of the object as we normally would.
+
+A special macro is provided to add a single char at a time to a
+growing object.  This allows the use of register variables, which
+break the ordinary 'growth' macro.
+
+Summary:
+	We allocate large chunks.
+	We carve out one object at a time from the current chunk.
+	Once carved, an object never moves.
+	We are free to append data of any size to the currently
+	  growing object.
+	Exactly one object is growing in an obstack at any one time.
+	You can run one obstack per control block.
+	You may have as many control blocks as you dare.
+	Because of the way we do it, you can `unwind' an obstack
+	  back to a previous state. (You may remove objects much
+	  as you would with a stack.)

+   The former two functions operate on STRING with length LENGTH,

+   with lengths LENGTH1 and LENGTH2, respectively.
+
+   re_match() matches the compiled pattern in BUFP against the string,

+
+   re_search() first tries matching at index START, then it tries to match
+   starting from index START + 1, and so on.  The last start position tried

+   way as re_match().)
+
+   The parameter STOP of re_{match,search}_2 specifies that no match exceeding
+   the first STOP characters of the concatenation of the strings should be
+   concerned.
+
+   If REGS is not NULL, and BUFP->no_sub is not set, the offsets of the match
+   and all groups is stroed in REGS.  (For the "_2" variants, the offsets are
+   computed relative to the concatenation, not relative to the individual
+   strings.)
+
+   On success, re_match* functions return the length of the match, re_search*
+   return the position of the start of the match.  Return value -1 means no

 #
 # To use these routines:
 #
-#    1) Copy this file to somewhere (e.g. ~/.git-completion.sh).
-#    2) Added the following line to your .bashrc:
-#        source ~/.git-completion.sh
-#
-#    3) You may want to make sure the git executable is available
-#       in your PATH before this script is sourced, as some caching
-#       is performed while the script loads.  If git isn't found
-#       at source time then all lookups will be done on demand,
-#       which may be slightly slower.
-#
-#    4) Consider changing your PS1 to also show the current branch:
-#        PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
-#
-#       The argument to __git_ps1 will be displayed only if you
-#       are currently in a git repository.  The %s token will be
-#       the name of the current branch.
-#
-#       In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty
-#       value, unstaged (*) and staged (+) changes will be shown next
-#       to the branch name.  You can configure this per-repository
-#       with the bash.showDirtyState variable, which defaults to true
-#       once GIT_PS1_SHOWDIRTYSTATE is enabled.
-#
-#       You can also see if currently something is stashed, by setting
-#       GIT_PS1_SHOWSTASHSTATE to a nonempty value. If something is stashed,
-#       then a '$' will be shown next to the branch name.
-#
-#       If you would like to see if there're untracked files, then you can
-#       set GIT_PS1_SHOWUNTRACKEDFILES to a nonempty value. If there're
-#       untracked files, then a '%' will be shown next to the branch name.
-#
-# To submit patches:
-#
-#    *) Read Documentation/SubmittingPatches
-#    *) Send all patches to the current maintainer:
-#
-#       "Shawn O. Pearce" <spearce@spearce.org>
-#
-#    *) Always CC the Git mailing list:
-#
-#       git@vger.kernel.org
+#    1) Copy this file to somewhere (e.g. ~/.git-completion.bash).

+#
+# This script allows you to see repository status in your prompt.
+#
+# To enable:
+#
+#    1) Copy this file to somewhere (e.g. ~/.git-prompt.sh).
+#    2) Add the following line to your .bashrc/.zshrc:
+#        source ~/.git-prompt.sh
+#    3a) Change your PS1 to call __git_ps1 as
+#        command-substitution:
+#        Bash: PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
+#        ZSH:  setopt PROMPT_SUBST ; PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '
+#        the optional argument will be used as format string.
+#    3b) Alternatively, for a slightly faster prompt, __git_ps1 can
+#        be used for PROMPT_COMMAND in Bash or for precmd() in Zsh
+#        with two parameters, <pre> and <post>, which are strings
+#        you would put in $PS1 before and after the status string
+#        generated by the git-prompt machinery.  e.g.
+#        Bash: PROMPT_COMMAND='__git_ps1 "\u@\h:\w" "\\\$ "'
+#          will show username, at-sign, host, colon, cwd, then
+#          various status string, followed by dollar and SP, as
+#          your prompt.
+#        ZSH:  precmd () { __git_ps1 "%n" ":%~$ " "|%s" }
+#          will show username, pipe, then various status string,
+#          followed by colon, cwd, dollar and SP, as your prompt.
+#        Optionally, you can supply a third argument with a printf
+#        format string to finetune the output of the branch status
+#
+# The repository status will be displayed only if you are currently in a
+# git repository. The %s token is the placeholder for the shown status.
+#
+# The prompt status always includes the current branch name.
+#
+# In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty value,
+# unstaged (*) and staged (+) changes will be shown next to the branch
+# name.  You can configure this per-repository with the
+# bash.showDirtyState variable, which defaults to true once
+# GIT_PS1_SHOWDIRTYSTATE is enabled.
+#
+# You can also see if currently something is stashed, by setting
+# GIT_PS1_SHOWSTASHSTATE to a nonempty value. If something is stashed,
+# then a '$' will be shown next to the branch name.
+#
+# If you would like to see if there're untracked files, then you can set
+# GIT_PS1_SHOWUNTRACKEDFILES to a nonempty value. If there're untracked
+# files, then a '%' will be shown next to the branch name.  You can
+# configure this per-repository with the bash.showUntrackedFiles
+# variable, which defaults to true once GIT_PS1_SHOWUNTRACKEDFILES is
+# enabled.
+#
+# If you would like to see the difference between HEAD and its upstream,
+# set GIT_PS1_SHOWUPSTREAM="auto".  A "<" indicates you are behind, ">"
+# indicates you are ahead, "<>" indicates you have diverged and "="
+# indicates that there is no difference. You can further control
+# behaviour by setting GIT_PS1_SHOWUPSTREAM to a space-separated list
+# of values:
+#
+#     verbose       show number of commits ahead/behind (+/-) upstream
+#     name          if verbose, then also show the upstream abbrev name
+#     legacy        don't use the '--count' option available in recent
+#                   versions of git-rev-list
+#     git           always compare HEAD to @{upstream}
+#     svn           always compare HEAD to your SVN upstream
+#
+# By default, __git_ps1 will compare HEAD to your SVN upstream if it can
+# find one, or @{upstream} otherwise.  Once you have set
+# GIT_PS1_SHOWUPSTREAM, you can override it on a per-repository basis by
+# setting the bash.showUpstream config variable.
+#
+# If you would like to see more information about the identity of
+# commits checked out as a detached HEAD, set GIT_PS1_DESCRIBE_STYLE
+# to one of these values:
+#
+#     contains      relative to newer annotated tag (v1.6.3.2~35)
+#     branch        relative to newer tag or branch (master~4)
+#     describe      relative to older annotated tag (v1.6.3.1-13-gdd42c2f)
+#     default       exactly matching tag
+#
+# If you would like a colored hint about the current dirty state, set
+# GIT_PS1_SHOWCOLORHINTS to a nonempty value. The colors are based on
+# the colored output of "git status -sb" and are available only when
+# using __git_ps1 for PROMPT_COMMAND or precmd.
+#
+# If you would like __git_ps1 to do nothing in the case when the current
+# directory is set up to be ignored by git, then set
+# GIT_PS1_HIDE_IF_PWD_IGNORED to a nonempty value. Override this on the
+# repository level by setting bash.hideIfPwdIgnored to "false".

+===============
+
+NAME
+----
+git-contacts - List people who might be interested in a set of changes
+
+
+SYNOPSIS
+--------
+[verse]
+'git contacts' (<patch>|<range>|<rev>)...
+
+
+DESCRIPTION
+-----------
+
+Given a set of changes, specified as patch files or revisions, determine people
+who might be interested in those changes.  This is done by consulting the
+history of each patch or revision hunk to find people mentioned by commits
+which touched the lines of files under consideration.
+
+Input consists of one or more patch files or revision arguments.  A revision
+argument can be a range or a single `<rev>` which is interpreted as
+`<rev>..HEAD`, thus the same revision arguments are accepted as for
+linkgit:git-format-patch[1]. Patch files and revision arguments can be combined
+in the same invocation.
+
+This command can be useful for determining the list of people with whom to
+discuss proposed changes, or for finding the list of recipients to Cc: when
+submitting a patch series via `git send-email`. For the latter case, `git
+contacts` can be used as the argument to `git send-email`'s `--cc-cmd` option.
+
+
+DISCUSSION
+----------
+
+`git blame` is invoked for each hunk in a patch file or revision.  For each
+commit mentioned by `git blame`, the commit message is consulted for people who
+authored, reviewed, signed, acknowledged, or were Cc:'d.  Once the list of
+participants is known, each person's relevance is computed by considering how
+many commits mentioned that person compared with the total number of commits
+under consideration.  The final output consists only of participants who exceed
+a minimum threshold of participation.
+
+
+OUTPUT
+------
+
+For each person of interest, a single line is output, terminated by a newline.
+If the person's name is known, ``Name $$<user@host>$$'' is printed; otherwise
+only ``$$<user@host>$$'' is printed.
+
+
+EXAMPLES
+--------
+
+* Consult patch files:
++
+------------
+$ git contacts feature/*.patch
+------------
+
+* Revision range:
++
+------------
+$ git contacts R1..R2
+------------
+
+* From a single revision to `HEAD`:
++
+------------
+$ git contacts origin
+------------
+
+* Helper for `git send-email`:
++
+------------
+$ git send-email --cc-cmd='git contacts' feature/*.patch
+------------
+
+
+LIMITATIONS
+-----------
+
+Several conditions controlling a person's significance are currently
+hard-coded, such as minimum participation level (10%), blame date-limiting (5
+years), and `-C` level for detecting moved and copied lines (a single `-C`). In
+the future, these conditions may become configurable.

-#!/usr/bin/perl
-#
-# A daemon that waits for update events sent by its companion
-# post-receive-cinotify hook, checks out a new copy of source,
-# compiles it, and emails the guilty parties if the compile
-# (and optionally test suite) fails.
-#
-# To use this daemon, configure it and run it.  It will disconnect
-# from your terminal and fork into the background.  The daemon must
-# have local filesystem access to the source repositories, as it
-# uses objects/info/alternates to avoid copying objects.
-#
-# Add its companion post-receive-cinotify hook as the post-receive
-# hook to each repository that the daemon should monitor.  Yes, a
-# single daemon can monitor more than one repository.
-#
-# To use multiple daemons on the same system, give them each a
-# unique queue file and tmpdir.
-#
-# Global Config
-# -------------
-# Reads from a Git style configuration file.  This will be
-# ~/.gitconfig by default but can be overridden by setting
-# the GIT_CONFIG_FILE environment variable before starting.
-#
-# cidaemon.smtpHost
-#   Hostname of the SMTP server the daemon will send email
-#   through.  Defaults to 'localhost'.
-#
-# cidaemon.smtpUser
-#   Username to authenticate to the SMTP server as.  This
-#   variable is optional; if it is not supplied then no
-#   authentication will be performed.
-#
-# cidaemon.smtpPassword
-#   Password to authenticate to the SMTP server as.  This
-#   variable is optional.  If not supplied but smtpUser was,
-#   the daemon prompts for the password before forking into
-#   the background.
-#
-# cidaemon.smtpAuth
-#   Type of authentication to perform with the SMTP server.
-#   If set to 'login' and smtpUser was defined, this will
-#   use the AUTH LOGIN command, which is suitable for use
-#   with at least one version of Microsoft Exchange Server.
-#   If not set the daemon will use whatever auth methods
-#   are supported by your version of Net::SMTP.
-#
-# cidaemon.email
-#   Email address that daemon generated emails will be sent
-#   from.  This should be a useful email address within your
-#   organization.  Required.
-#
-# cidaemon.name
-#   Human friendly name that the daemon will send emails as.
-#   Defaults to 'cidaemon'.
-#
-# cidaemon.scanDelay
-#   Number of seconds to sleep between polls of the queue file.
-#   Defaults to 60.
-#
-# cidaemon.recentCache
-#   Number of recent commit SHA-1s per repository to cache and
-#   skip building if they appear again.  This is useful to avoid
-#   rebuilding the same commit multiple times just because it was
-#   pushed into more than one branch.  Defaults to 100.
-#
-# cidaemon.tmpdir
-#   Scratch directory to create the builds within.  The daemon
-#   makes a new subdirectory for each build, then deletes it when
-#   the build has finished.  The pid file is also placed here.
-#   Defaults to '/tmp'.
-#
-# cidaemon.queue
-#   Path to the queue file that the post-receive-cinotify hook
-#   appends events to.  This file is polled by the daemon.  It
-#   must not be on an NFS mount (uses flock).  Required.
-#
-# cidaemon.nocc
-#   Perl regex patterns to match against author and committer
-#   lines.  If a pattern matches, that author or committer will
-#   not be notified of a build failure.
-#
-# Per Repository Config
-# ----------------------
-# Read from the source repository's config file.
-#
-# builder.command
-#   Shell command to execute the build.  This command must
-#   return 0 on "success" and non-zero on failure.  If you
-#   also want to run a test suite, make sure your command
-#   does that too.  Required.
-#
-# builder.queue
-#   Queue file to notify the cidaemon through.  Should match
-#   cidaemon.queue.  If not set the hook will not notify the
-#   cidaemon.
-#
-# builder.skip
-#   Perl regex patterns of refs that should not be sent to
-#   cidaemon.  Updates of these refs will be ignored.
-#
-# builder.newBranchBase
-#   Glob patterns of refs that should be used to form the
-#   'old' revions of a newly created ref.  This should set
-#   to be globs that match your 'mainline' branches.  This
-#   way a build failure of a brand new topic branch does not
-#   attempt to email everyone since the beginning of time;
-#   instead it only emails those authors of commits not in
-#   these 'mainline' branches.

+                       arguments are OK.  They are processed in order, and the
+                       first matching entry found is returned via the credential
+                       helper protocol (see below).
+
+                       When no -f option is given, .authinfo.gpg, .netrc.gpg,
+		       .authinfo, and .netrc files in your home directory are used
+		       in this order.
+
+  -k|--insecure      : ignore bad file ownership or permissions
+
+  -d|--debug         : turn on debugging (developer info)
+
+  -v|--verbose       : be more verbose (show files and information found)
+
+To enable this credential helper:
+
+  git config credential.helper '$shortname -f AUTHFILE1 -f AUTHFILE2'
+
+(Note that Git will prepend "git-credential-" to the helper name and look for it
+in the path.)
+
+...and if you want lots of debugging info:
+
+  git config credential.helper '$shortname -f AUTHFILE -d'
+
+...or to see the files opened and data found:
+
+  git config credential.helper '$shortname -f AUTHFILE -v'
+
+Only "get" mode is supported by this credential helper.  It opens every AUTHFILE
+and looks for the first entry that matches the requested search criteria:
+
+ 'port|protocol':
+   The protocol that will be used (e.g., https). (protocol=X)
+
+ 'machine|host':
+   The remote hostname for a network credential. (host=X)
+
+ 'path':
+   The path with which the credential will be used. (path=X)
+
+ 'login|user|username':
+   The credential’s username, if we already have one. (username=X)
+
+Thus, when we get this query on STDIN:
+
+host=github.com
+protocol=https
+username=tzz
+
+this credential helper will look for the first entry in every AUTHFILE that
+matches
+
+machine github.com port https login tzz
+
+OR
+
+machine github.com protocol https login tzz
+
+OR... etc. acceptable tokens as listed above.  Any unknown tokens are
+simply ignored.
+
+Then, the helper will print out whatever tokens it got from the entry, including
+"password" tokens, mapping back to Git's helper protocol; e.g. "port" is mapped
+back to "protocol".  Any redundant entry tokens (part of the original query) are
+skipped.
+
+Again, note that only the first matching entry from all the AUTHFILEs, processed
+in the sequence given on the command line, is used.
+
+Netrc/authinfo tokens can be quoted as 'STRING' or "STRING".
+
+No caching is performed by this credential helper.

+diff-highlight
+==============
+
+Line oriented diffs are great for reviewing code, because for most
+hunks, you want to see the old and the new segments of code next to each
+other. Sometimes, though, when an old line and a new line are very
+similar, it's hard to immediately see the difference.
+
+You can use "--color-words" to highlight only the changed portions of
+lines. However, this can often be hard to read for code, as it loses
+the line structure, and you end up with oddly formatted bits.
+
+Instead, this script post-processes the line-oriented diff, finds pairs
+of lines, and highlights the differing segments.  It's currently very
+simple and stupid about doing these tasks. In particular:
+
+  1. It will only highlight hunks in which the number of removed and
+     added lines is the same, and it will pair lines within the hunk by
+     position (so the first removed line is compared to the first added
+     line, and so forth). This is simple and tends to work well in
+     practice. More complex changes don't highlight well, so we tend to
+     exclude them due to the "same number of removed and added lines"
+     restriction. Or even if we do try to highlight them, they end up
+     not highlighting because of our "don't highlight if the whole line
+     would be highlighted" rule.
+
+  2. It will find the common prefix and suffix of two lines, and
+     consider everything in the middle to be "different". It could
+     instead do a real diff of the characters between the two lines and
+     find common subsequences. However, the point of the highlight is to
+     call attention to a certain area. Even if some small subset of the
+     highlighted area actually didn't change, that's OK. In practice it
+     ends up being more readable to just have a single blob on the line
+     showing the interesting bit.
+
+The goal of the script is therefore not to be exact about highlighting
+changes, but to call attention to areas of interest without being
+visually distracting.  Non-diff lines and existing diff coloration is
+preserved; the intent is that the output should look exactly the same as
+the input, except for the occasional highlight.
+
+Use
+---
+
+You can try out the diff-highlight program with:
+
+---------------------------------------------
+git log -p --color | /path/to/diff-highlight
+---------------------------------------------
+
+If you want to use it all the time, drop it in your $PATH and put the
+following in your git configuration:
+
+---------------------------------------------
+[pager]
+	log = diff-highlight | less
+	show = diff-highlight | less
+	diff = diff-highlight | less
+---------------------------------------------
+
+
+Color Config
+------------
+
+You can configure the highlight colors and attributes using git's
+config. The colors for "old" and "new" lines can be specified
+independently. There are two "modes" of configuration:
+
+  1. You can specify a "highlight" color and a matching "reset" color.
+     This will retain any existing colors in the diff, and apply the
+     "highlight" and "reset" colors before and after the highlighted
+     portion.
+
+  2. You can specify a "normal" color and a "highlight" color. In this
+     case, existing colors are dropped from that line. The non-highlighted
+     bits of the line get the "normal" color, and the highlights get the
+     "highlight" color.
+
+If no "new" colors are specified, they default to the "old" colors. If
+no "old" colors are specified, the default is to reverse the foreground
+and background for highlighted portions.
+
+Examples:
+
+---------------------------------------------
+# Underline highlighted portions
+[color "diff-highlight"]
+oldHighlight = ul
+oldReset = noul
+---------------------------------------------
+
+---------------------------------------------
+# Varying background intensities
+[color "diff-highlight"]
+oldNormal = "black #f8cbcb"
+oldHighlight = "black #ffaaaa"
+newNormal = "black #cbeecb"
+newHighlight = "black #aaffaa"
+---------------------------------------------
+
+
+Bugs
+----
+
+Because diff-highlight relies on heuristics to guess which parts of
+changes are important, there are some cases where the highlighting is
+more distracting than useful. Fortunately, these cases are rare in
+practice, and when they do occur, the worst case is simply a little
+extra highlighting. This section documents some cases known to be
+sub-optimal, in case somebody feels like working on improving the
+heuristics.
+
+1. Two changes on the same line get highlighted in a blob. For example,
+   highlighting:
+
+----------------------------------------------
+-foo(buf, size);
++foo(obj->buf, obj->size);
+----------------------------------------------
+
+   yields (where the inside of "+{}" would be highlighted):
+
+----------------------------------------------
+-foo(buf, size);
++foo(+{obj->buf, obj->}size);
+----------------------------------------------
+
+   whereas a more semantically meaningful output would be:
+
+----------------------------------------------
+-foo(buf, size);
++foo(+{obj->}buf, +{obj->}size);
+----------------------------------------------
+
+   Note that doing this right would probably involve a set of
+   content-specific boundary patterns, similar to word-diff. Otherwise
+   you get junk like:
+
+-----------------------------------------------------
+-this line has some -{i}nt-{ere}sti-{ng} text on it
++this line has some +{fa}nt+{a}sti+{c} text on it
+-----------------------------------------------------
+
+   which is less readable than the current output.
+
+2. The multi-line matching assumes that lines in the pre- and post-image
+   match by position. This is often the case, but can be fooled when a
+   line is removed from the top and a new one added at the bottom (or
+   vice versa). Unless the lines in the middle are also changed, diffs
+   will show this as two hunks, and it will not get highlighted at all
+   (which is good). But if the lines in the middle are changed, the
+   highlighting can be misleading. Here's a pathological case:
+
+-----------------------------------------------------
+-one
+-two
+-three
+-four
++two 2
++three 3
++four 4
++five 5
+-----------------------------------------------------
+
+   which gets highlighted as:
+
+-----------------------------------------------------
+-one
+-t-{wo}
+-three
+-f-{our}
++two 2
++t+{hree 3}
++four 4
++f+{ive 5}
+-----------------------------------------------------
+
+   because it matches "two" to "three 3", and so forth. It would be
+   nicer as:
+
+-----------------------------------------------------
+-one
+-two
+-three
+-four
++two +{2}
++three +{3}
++four +{4}
++five 5
+-----------------------------------------------------
+
+   which would probably involve pre-matching the lines into pairs
+   according to some heuristic.

-git-p4 - Perforce <-> Git converter using git-fast-import
-
-Usage
-=====
-
-git-p4 can be used in two different ways:
-
-1) To import changes from Perforce to a Git repository, using "git-p4 sync".
-
-2) To submit changes from Git back to Perforce, using "git-p4 submit".
-
-Importing
-=========
-
-Simply start with
-
-  git-p4 clone //depot/path/project
-
-or
-
-  git-p4 clone //depot/path/project myproject
-
-This will:
-
-1) Create an empty git repository in a subdirectory called "project" (or
-"myproject" with the second command)
-
-2) Import the head revision from the given Perforce path into a git branch
-called "p4" (remotes/p4 actually)
-
-3) Create a master branch based on it and check it out.
-
-If you want the entire history (not just the head revision) then you can simply
-append a "@all" to the depot path:
-
-  git-p4 clone //depot/project/main@all myproject
-
-
-
-If you want more control you can also use the git-p4 sync command directly:
-
-  mkdir repo-git
-  cd repo-git
-  git init
-  git-p4 sync //path/in/your/perforce/depot
-
-This will import the current head revision of the specified depot path into a
-"remotes/p4/master" branch of your git repository. You can use the
---branch=mybranch option to import into a different branch.
-
-If you want to import the entire history of a given depot path simply use:
-
-  git-p4 sync //path/in/depot@all
-
-
-Note:
-
-To achieve optimal compression you may want to run 'git repack -a -d -f' after
-a big import. This may take a while.
-
-Incremental Imports
-===================
-
-After an initial import you can continue to synchronize your git repository
-with newer changes from the Perforce depot by just calling
-
-  git-p4 sync
-
-in your git repository. By default the "remotes/p4/master" branch is updated.
-
-Advanced Setup
-==============
-
-Suppose you have a periodically updated git repository somewhere, containing a
-complete import of a Perforce project. This repository can be cloned and used
-with git-p4. When updating the cloned repository with the "sync" command,
-git-p4 will try to fetch changes from the original repository first. The git
-protocol used with this is usually faster than importing from Perforce
-directly.
-
-This behaviour can be disabled by setting the "git-p4.syncFromOrigin" git
-configuration variable to "false".
-
-Updating
-========
-
-A common working pattern is to fetch the latest changes from the Perforce depot
-and merge them with local uncommitted changes. The recommended way is to use
-git's rebase mechanism to preserve linear history. git-p4 provides a convenient
-
-  git-p4 rebase
-
-command that calls git-p4 sync followed by git rebase to rebase the current
-working branch.
-
-Submitting
-==========
-
-git-p4 has support for submitting changes from a git repository back to the
-Perforce depot. This requires a Perforce checkout separate from your git
-repository. To submit all changes that are in the current git branch but not in
-the "p4" branch (or "origin" if "p4" doesn't exist) simply call
-
-    git-p4 submit
-
-in your git repository. If you want to submit changes in a specific branch that
-is not your current git branch you can also pass that as an argument:
-
-    git-p4 submit mytopicbranch
-
-You can override the reference branch with the --origin=mysourcebranch option.
-
-If a submit fails you may have to "p4 resolve" and submit manually. You can
-continue importing the remaining changes with
-
-  git-p4 submit --continue
-
-Example
-=======
-
-# Clone a repository
-  git-p4 clone //depot/path/project
-# Enter the newly cloned directory
-  cd project
-# Do some work...
-  vi foo.h
-# ... and commit locally to gi
-  git commit foo.h
-# In the meantime somebody submitted changes to the Perforce depot. Rebase your latest
-# changes against the latest changes in Perforce:
-  git-p4 rebase
-# Submit your locally committed changes back to Perforce
-  git-p4 submit
-# ... and synchronize with Perforce
-  git-p4 rebase
-
-
-Configuration parameters
-========================
-
-git-p4.user ($P4USER)
-
-Allows you to specify the username to use to connect to the Perforce repository.
-
-  git config [--global] git-p4.user public
-
-git-p4.password ($P4PASS)
-
-Allows you to specify the password to use to connect to the Perforce repository.
-Warning this password will be visible on the command-line invocation of the p4 binary.
-
-  git config [--global] git-p4.password public1234
-
-git-p4.port ($P4PORT)
-
-Specify the port to be used to contact the Perforce server. As this will be passed
-directly to the p4 binary, it may be in the format host:port as well.
-
-  git config [--global] git-p4.port codes.zimbra.com:2666
-
-git-p4.host ($P4HOST)
-
-Specify the host to contact for a Perforce repository.
-
-  git config [--global] git-p4.host perforce.example.com
-
-git-p4.client ($P4CLIENT)
-
-Specify the client name to use
-
-  git config [--global] git-p4.client public-view
-
-git-p4.allowSubmit
-
-  git config [--global] git-p4.allowSubmit false
-
-git-p4.syncFromOrigin
-
-A useful setup may be that you have a periodically updated git repository
-somewhere that contains a complete import of a Perforce project. That git
-repository can be used to clone the working repository from and one would
-import from Perforce directly after cloning using git-p4. If the connection to
-the Perforce server is slow and the working repository hasn't been synced for a
-while it may be desirable to fetch changes from the origin git repository using
-the efficient git protocol. git-p4 supports this setup by calling "git fetch origin"
-by default if there is an origin branch. You can disable this using:
-
-  git config [--global] git-p4.syncFromOrigin false
-
-git-p4.useclientspec
-
-  git config [--global] git-p4.useclientspec false
-
-Implementation Details...
-=========================
-
-* Changesets from Perforce are imported using git fast-import.
-* The import does not require anything from the Perforce client view as it just uses
-  "p4 print //depot/path/file#revision" to get the actual file contents.
-* Every imported changeset has a special [git-p4...] line at the
-  end of the log message that gives information about the corresponding
-  Perforce change number and is also used by git-p4 itself to find out
-  where to continue importing when doing incremental imports.
-  Basically when syncing it extracts the perforce change number of the
-  latest commit in the "p4" branch and uses "p4 changes //depot/path/...@changenum,#head"
-  to find out which changes need to be imported.
-* git-p4 submit uses "git rev-list" to pick the commits between the "p4" branch
-  and the current branch.
-  The commits themselves are applied using git diff/format-patch ... | git apply

+git-jump
+========
+
+Git-jump is a script for helping you jump to "interesting" parts of your
+project in your editor. It works by outputting a set of interesting
+spots in the "quickfix" format, which editors like vim can use as a
+queue of places to visit (this feature is usually used to jump to errors
+produced by a compiler). For example, given a diff like this:
+
+------------------------------------
+diff --git a/foo.c b/foo.c
+index a655540..5a59044 100644
+--- a/foo.c
++++ b/foo.c
+@@ -1,3 +1,3 @@
+ int main(void) {
+-  printf("hello word!\n");
++  printf("hello world!\n");
+ }
+-----------------------------------
+
+git-jump will feed this to the editor:
+
+-----------------------------------
+foo.c:2: printf("hello word!\n");
+-----------------------------------
+
+Obviously this trivial case isn't that interesting; you could just open
+`foo.c` yourself. But when you have many changes scattered across a
+project, you can use the editor's support to "jump" from point to point.
+
+Git-jump can generate three types of interesting lists:
+
+  1. The beginning of any diff hunks.
+
+  2. The beginning of any merge conflict markers.
+
+  3. Any grep matches.
+
+
+Using git-jump
+--------------
+
+To use it, just drop git-jump in your PATH, and then invoke it like
+this:
+
+--------------------------------------------------
+# jump to changes not yet staged for commit
+git jump diff
+
+# jump to changes that are staged for commit; you can give
+# arbitrary diff options
+git jump diff --cached
+
+# jump to merge conflicts
+git jump merge
+
+# jump to all instances of foo_bar
+git jump grep foo_bar
+
+# same as above, but case-insensitive; you can give
+# arbitrary grep options
+git jump grep -i foo_bar
+--------------------------------------------------
+
+
+Related Programs
+----------------
+
+You can accomplish some of the same things with individual tools. For
+example, you can use `git mergetool` to start vimdiff on each unmerged
+file. `git jump merge` is for the vim-wielding luddite who just wants to
+jump straight to the conflict text with no fanfare.
+
+As of git v1.7.2, `git grep` knows the `--open-files-in-pager` option,
+which does something similar to `git jump grep`. However, it is limited
+to positioning the cursor to the correct line in only the first file,
+leaving you to locate subsequent hits in that file or other files using
+the editor or pager. By contrast, git-jump provides the editor with a
+complete list of files and line numbers for each match.
+
+
+Limitations
+-----------
+
+This scripts was written and tested with vim. Given that the quickfix
+format is the same as what gcc produces, I expect emacs users have a
+similar feature for iterating through the list, but I know nothing about
+how to activate it.
+
+The shell snippets to generate the quickfix lines will almost certainly
+choke on filenames with exotic characters (like newlines).

+			   git-multimail
+			   =============
+
+git-multimail is a tool for sending notification emails on pushes to a
+Git repository.  It includes a Python module called git_multimail.py,
+which can either be used as a hook script directly or can be imported
+as a Python module into another script.
+
+git-multimail is derived from the Git project's old
+contrib/hooks/post-receive-email, and is mostly compatible with that
+script.  See README.migrate-from-post-receive-email for details about
+the differences and for how to migrate from post-receive-email to
+git-multimail.
+
+git-multimail, like the rest of the Git project, is licensed under
+GPLv2 (see the COPYING file for details).
+
+Please note: although, as a convenience, git-multimail may be
+distributed along with the main Git project, development of
+git-multimail takes place in its own, separate project.  See section
+"Getting involved" below for more information.
+
+
+By default, for each push received by the repository, git-multimail:
+
+1. Outputs one email summarizing each reference that was changed.
+   These "reference change" (called "refchange" below) emails describe
+   the nature of the change (e.g., was the reference created, deleted,
+   fast-forwarded, etc.) and include a one-line summary of each commit
+   that was added to the reference.
+
+2. Outputs one email for each new commit that was introduced by the
+   reference change.  These "commit" emails include a list of the
+   files changed by the commit, followed by the diffs of files
+   modified by the commit.  The commit emails are threaded to the
+   corresponding reference change email via "In-Reply-To".  This style
+   (similar to the "git format-patch" style used on the Git mailing
+   list) makes it easy to scan through the emails, jump to patches
+   that need further attention, and write comments about specific
+   commits.  Commits are handled in reverse topological order (i.e.,
+   parents shown before children).  For example,
+
+   [git] branch master updated
+   + [git] 01/08: doc: fix xref link from api docs to manual pages
+   + [git] 02/08: api-credentials.txt: show the big picture first
+   + [git] 03/08: api-credentials.txt: mention credential.helper explicitly
+   + [git] 04/08: api-credentials.txt: add "see also" section
+   + [git] 05/08: t3510 (cherry-pick-sequence): add missing '&&'
+   + [git] 06/08: Merge branch 'rr/maint-t3510-cascade-fix'
+   + [git] 07/08: Merge branch 'mm/api-credentials-doc'
+   + [git] 08/08: Git 1.7.11-rc2
+
+   Each commit appears in exactly one commit email, the first time
+   that it is pushed to the repository.  If a commit is later merged
+   into another branch, then a one-line summary of the commit is
+   included in the reference change email (as usual), but no
+   additional commit email is generated.
+
+   By default, reference change emails have their "Reply-To" field set
+   to the person who pushed the change, and commit emails have their
+   "Reply-To" field set to the author of the commit.
+
+3. Output one "announce" mail for each new annotated tag, including
+   information about the tag and optionally a shortlog describing the
+   changes since the previous tag.  Such emails might be useful if you
+   use annotated tags to mark releases of your project.
+
+
+Requirements
+------------
+
+* Python 2.x, version 2.4 or later.  No non-standard Python modules
+  are required.  git-multimail does *not* currently work with Python
+  3.x.
+
+  The example scripts invoke Python using the following shebang line
+  (following PEP 394 [1]):
+
+      #! /usr/bin/env python2
+
+  If your system's Python2 interpreter is not in your PATH or is not
+  called "python2", you can change the lines accordingly.  Or you can
+  invoke the Python interpreter explicitly, for example via a tiny
+  shell script like
+
+      #! /bin/sh
+      /usr/local/bin/python /path/to/git_multimail.py "$@"
+
+* The "git" command must be in your PATH.  git-multimail is known to
+  work with Git versions back to 1.7.1.  (Earlier versions have not
+  been tested; if you do so, please report your results.)
+
+* To send emails using the default configuration, a standard sendmail
+  program must be located at '/usr/sbin/sendmail' or
+  '/usr/lib/sendmail' and must be configured correctly to send emails.
+  If this is not the case, set multimailhook.sendmailCommand, or see
+  the multimailhook.mailer configuration variable below for how to
+  configure git-multimail to send emails via an SMTP server.
+
+
+Invocation
+----------
+
+git_multimail.py is designed to be used as a "post-receive" hook in a
+Git repository (see githooks(5)).  Link or copy it to
+$GIT_DIR/hooks/post-receive within the repository for which email
+notifications are desired.  Usually it should be installed on the
+central repository for a project, to which all commits are eventually
+pushed.
+
+For use on pre-v1.5.1 Git servers, git_multimail.py can also work as
+an "update" hook, taking its arguments on the command line.  To use
+this script in this manner, link or copy it to $GIT_DIR/hooks/update.
+Please note that the script is not completely reliable in this mode
+[2].
+
+Alternatively, git_multimail.py can be imported as a Python module
+into your own Python post-receive script.  This method is a bit more
+work, but allows the behavior of the hook to be customized using
+arbitrary Python code.  For example, you can use a custom environment
+(perhaps inheriting from GenericEnvironment or GitoliteEnvironment) to
+
+* change how the user who did the push is determined
+
+* read users' email addresses from an LDAP server or from a database
+
+* decide which users should be notified about which commits based on
+  the contents of the commits (e.g., for users who want to be notified
+  only about changes affecting particular files or subdirectories)
+
+Or you can change how emails are sent by writing your own Mailer
+class.  The "post-receive" script in this directory demonstrates how
+to use git_multimail.py as a Python module.  (If you make interesting
+changes of this type, please consider sharing them with the
+community.)
+
+
+Configuration
+-------------
+
+By default, git-multimail mostly takes its configuration from the
+following "git config" settings:
+
+multimailhook.environment
+
+    This describes the general environment of the repository.
+    Currently supported values:
+
+    "generic" -- the username of the pusher is read from $USER and the
+        repository name is derived from the repository's path.
+
+    "gitolite" -- the username of the pusher is read from $GL_USER and
+        the repository name from $GL_REPO.
+
+    If neither of these environments is suitable for your setup, then
+    you can implement a Python class that inherits from Environment
+    and instantiate it via a script that looks like the example
+    post-receive script.
+
+    The environment value can be specified on the command line using
+    the --environment option.  If it is not specified on the command
+    line or by multimailhook.environment, then it defaults to
+    "gitolite" if the environment contains variables $GL_USER and
+    $GL_REPO; otherwise "generic".
+
+multimailhook.repoName
+
+    A short name of this Git repository, to be used in various places
+    in the notification email text.  The default is to use $GL_REPO
+    for gitolite repositories, or otherwise to derive this value from
+    the repository path name.
+
+multimailhook.mailingList
+
+    The list of email addresses to which notification emails should be
+    sent, as RFC 2822 email addresses separated by commas.  This
+    configuration option can be multivalued.  Leave it unset or set it
+    to the empty string to not send emails by default.  The next few
+    settings can be used to configure specific address lists for
+    specific types of notification email.
+
+multimailhook.refchangeList
+
+    The list of email addresses to which summary emails about
+    reference changes should be sent, as RFC 2822 email addresses
+    separated by commas.  This configuration option can be
+    multivalued.  The default is the value in
+    multimailhook.mailingList.  Set this value to the empty string to
+    prevent reference change emails from being sent even if
+    multimailhook.mailingList is set.
+
+multimailhook.announceList
+
+    The list of email addresses to which emails about new annotated
+    tags should be sent, as RFC 2822 email addresses separated by
+    commas.  This configuration option can be multivalued.  The
+    default is the value in multimailhook.refchangeList or
+    multimailhook.mailingList.  Set this value to the empty string to
+    prevent annotated tag announcement emails from being sent even if
+    one of the other values is set.
+
+multimailhook.commitList
+
+    The list of email addresses to which emails about individual new
+    commits should be sent, as RFC 2822 email addresses separated by
+    commas.  This configuration option can be multivalued.  The
+    default is the value in multimailhook.mailingList.  Set this value
+    to the empty string to prevent notification emails about
+    individual commits from being sent even if
+    multimailhook.mailingList is set.
+
+multimailhook.announceShortlog
+
+    If this option is set to true, then emails about changes to
+    annotated tags include a shortlog of changes since the previous
+    tag.  This can be useful if the annotated tags represent releases;
+    then the shortlog will be a kind of rough summary of what has
+    happened since the last release.  But if your tagging policy is
+    not so straightforward, then the shortlog might be confusing
+    rather than useful.  Default is false.
+
+multimailhook.refchangeShowLog
+
+    If this option is set to true, then summary emails about reference
+    changes will include a detailed log of the added commits in
+    addition to the one line summary.  The log is generated by running
+    "git log" with the options specified in multimailhook.logOpts.
+    Default is false.
+
+multimailhook.mailer
+
+    This option changes the way emails are sent.  Accepted values are:
+
+    - sendmail (the default): use the command /usr/sbin/sendmail or
+      /usr/lib/sendmail (or sendmailCommand, if configured).  This
+      mode can be further customized via the following options:
+
+       multimailhook.sendmailCommand
+
+           The command used by mailer "sendmail" to send emails.  Shell
+           quoting is allowed in the value of this setting, but remember that
+           Git requires double-quotes to be escaped; e.g.,
+
+             git config multimailhook.sendmailcommand '/usr/sbin/sendmail -oi -t -F \"Git Repo\"'
+
+           Default is '/usr/sbin/sendmail -oi -t' or
+           '/usr/lib/sendmail -oi -t' (depending on which file is
+           present and executable).
+
+       multimailhook.envelopeSender
+
+           If set then pass this value to sendmail via the -f option to set
+           the envelope sender address.
+
+    - smtp: use Python's smtplib.  This is useful when the sendmail
+      command is not available on the system.  This mode can be
+      further customized via the following options:
+
+       multimailhook.smtpServer
+
+           The name of the SMTP server to connect to.  The value can
+           also include a colon and a port number; e.g.,
+           "mail.example.com:25".  Default is 'localhost' using port
+           25.
+
+       multimailhook.envelopeSender
+
+           The sender address to be passed to the SMTP server.  If
+           unset, then the value of multimailhook.from is used.
+
+multimailhook.from
+
+    If set then use this value in the From: field of generated emails.
+    If unset, then use the repository's user configuration (user.name
+    and user.email).  If user.email is also unset, then use
+    multimailhook.envelopeSender.
+
+multimailhook.administrator
+
+    The name and/or email address of the administrator of the Git
+    repository; used in FOOTER_TEMPLATE.  Default is
+    multimailhook.envelopesender if it is set; otherwise a generic
+    string is used.
+
+multimailhook.emailPrefix
+
+    All emails have this string prepended to their subjects, to aid
+    email filtering (though filtering based on the X-Git-* email
+    headers is probably more robust).  Default is the short name of
+    the repository in square brackets; e.g., "[myrepo]".
+
+multimailhook.emailMaxLines
+
+    The maximum number of lines that should be included in the body of
+    a generated email.  If not specified, there is no limit.  Lines
+    beyond the limit are suppressed and counted, and a final line is
+    added indicating the number of suppressed lines.
+
+multimailhook.emailMaxLineLength
+
+    The maximum length of a line in the email body.  Lines longer than
+    this limit are truncated to this length with a trailing " [...]"
+    added to indicate the missing text.  The default is 500, because
+    (a) diffs with longer lines are probably from binary files, for
+    which a diff is useless, and (b) even if a text file has such long
+    lines, the diffs are probably unreadable anyway.  To disable line
+    truncation, set this option to 0.
+
+multimailhook.maxCommitEmails
+
+    The maximum number of commit emails to send for a given change.
+    When the number of patches is larger that this value, only the
+    summary refchange email is sent.  This can avoid accidental
+    mailbombing, for example on an initial push.  To disable commit
+    emails limit, set this option to 0.  The default is 500.
+
+multimailhook.emailStrictUTF8
+
+    If this boolean option is set to "true", then the main part of the
+    email body is forced to be valid UTF-8.  Any characters that are
+    not valid UTF-8 are converted to the Unicode replacement
+    character, U+FFFD.  The default is "true".
+
+multimailhook.diffOpts
+
+    Options passed to "git diff-tree" when generating the summary
+    information for ReferenceChange emails.  Default is "--stat
+    --summary --find-copies-harder".  Add -p to those options to
+    include a unified diff of changes in addition to the usual summary
+    output.  Shell quoting is allowed; see multimailhook.logOpts for
+    details.
+
+multimailhook.logOpts
+
+    Options passed to "git log" to generate additional info for
+    reference change emails (used only if refchangeShowLog is set).
+    For example, adding --graph will show the graph of revisions, -p
+    will show the complete diff, etc.  The default is empty.
+
+    Shell quoting is allowed; for example, a log format that contains
+    spaces can be specified using something like:
+
+      git config multimailhook.logopts '--pretty=format:"%h %aN <%aE>%n%s%n%n%b%n"'
+
+    If you want to set this by editing your configuration file
+    directly, remember that Git requires double-quotes to be escaped
+    (see git-config(1) for more information):
+
+      [multimailhook]
+              logopts = --pretty=format:\"%h %aN <%aE>%n%s%n%n%b%n\"
+
+multimailhook.commitLogOpts
+
+    Options passed to "git log" to generate additional info for
+    revision change emails.  For example, adding --ignore-all-spaces
+    will suppress whitespace changes.  The default options are "-C
+    --stat -p --cc".  Shell quoting is allowed; see
+    multimailhook.logOpts for details.
+
+multimailhook.emailDomain
+
+    Domain name appended to the username of the person doing the push
+    to convert it into an email address (via "%s@%s" % (username,
+    emaildomain)).  More complicated schemes can be implemented by
+    overriding Environment and overriding its get_pusher_email()
+    method.
+
+multimailhook.replyTo
+multimailhook.replyToCommit
+multimailhook.replyToRefchange
+
+    Addresses to use in the Reply-To: field for commit emails
+    (replyToCommit) and refchange emails (replyToRefchange).
+    multimailhook.replyTo is used as default when replyToCommit or
+    replyToRefchange is not set.  The value for these variables can be
+    either:
+
+    - An email address, which will be used directly.
+
+    - The value "pusher", in which case the pusher's address (if
+      available) will be used.  This is the default for refchange
+      emails.
+
+    - The value "author" (meaningful only for replyToCommit), in which
+      case the commit author's address will be used.  This is the
+      default for commit emails.
+
+    - The value "none", in which case the Reply-To: field will be
+      omitted.
+
+
+Email filtering aids
+--------------------
+
+All emails include extra headers to enable fine tuned filtering and
+give information for debugging.  All emails include the headers
+"X-Git-Host", "X-Git-Repo", "X-Git-Refname", and "X-Git-Reftype".
+ReferenceChange emails also include headers "X-Git-Oldrev" and "X-Git-Newrev";
+Revision emails also include header "X-Git-Rev".
+
+
+Customizing email contents
+--------------------------
+
+git-multimail mostly generates emails by expanding templates.  The
+templates can be customized.  To avoid the need to edit
+git_multimail.py directly, the preferred way to change the templates
+is to write a separate Python script that imports git_multimail.py as
+a module, then replaces the templates in place.  See the provided
+post-receive script for an example of how this is done.
+
+
+Customizing git-multimail for your environment
+----------------------------------------------
+
+git-multimail is mostly customized via an "environment" that describes
+the local environment in which Git is running.  Two types of
+environment are built in:
+
+* GenericEnvironment: a stand-alone Git repository.
+
+* GitoliteEnvironment: a Git repository that is managed by gitolite
+  [3].  For such repositories, the identity of the pusher is read from
+  environment variable $GL_USER, and the name of the repository is
+  read from $GL_REPO (if it is not overridden by
+  multimailhook.reponame).
+
+By default, git-multimail assumes GitoliteEnvironment if $GL_USER and
+$GL_REPO are set, and otherwise assumes GenericEnvironment.
+Alternatively, you can choose one of these two environments explicitly
+by setting a "multimailhook.environment" config setting (which can
+have the value "generic" or "gitolite") or by passing an --environment
+option to the script.
+
+If you need to customize the script in ways that are not supported by
+the existing environments, you can define your own environment class
+class using arbitrary Python code.  To do so, you need to import
+git_multimail.py as a Python module, as demonstrated by the example
+post-receive script.  Then implement your environment class; it should
+usually inherit from one of the existing Environment classes and
+possibly one or more of the EnvironmentMixin classes.  Then set the
+"environment" variable to an instance of your own environment class
+and pass it to run_as_post_receive_hook().
+
+The standard environment classes, GenericEnvironment and
+GitoliteEnvironment, are in fact themselves put together out of a
+number of mixin classes, each of which handles one aspect of the
+customization.  For the finest control over your configuration, you
+can specify exactly which mixin classes your own environment class
+should inherit from, and override individual methods (or even add your
+own mixin classes) to implement entirely new behaviors.  If you
+implement any mixins that might be useful to other people, please
+consider sharing them with the community!
+
+
+Getting involved

+The current maintainer is Michael Haggerty <mhagger@alum.mit.edu>.
+
+General discussion of git-multimail takes place on the main Git
+mailing list,
+
+    git@vger.kernel.org
+
+Please CC emails regarding git-multimail to me so that I don't
+overlook them.
+
+The git-multimail project itself is currently hosted on GitHub:
+
+    https://github.com/mhagger/git-multimail

+We use the GitHub issue tracker to keep track of bugs and feature
+requests, and GitHub pull requests to exchange patches (though, if you
+prefer, you can send patches via the Git mailing list with cc to me).
+Please sign off your patches as per the Git project practice.
+
+Please note that although a copy of git-multimail will probably be
+distributed in the "contrib" section of the main Git project,
+development takes place in the separate git-multimail repository on
+GitHub!  (Whenever enough changes to git-multimail have accumulated, a
+new code-drop of git-multimail will be submitted for inclusion in the
+Git project.)

+git-multimail is close to, but not exactly, a plug-in replacement for
+the old Git project script contrib/hooks/post-receive-email.  This
+document describes the differences and explains how to configure
+git-multimail to get behavior closest to that of post-receive-email.
+
+If you are in a hurry
+=====================
+
+A script called migrate-mailhook-config is included with
+git-multimail.  If you run this script within a Git repository that is
+configured to use post-receive-email, it will convert the
+configuration settings into the approximate equivalent settings for
+git-multimail.  For more information, run
+
+    migrate-mailhook-config --help
+
+
+Configuration differences
+=========================
+
+* The names of the config options for git-multimail are in namespace
+  "multimailhook.*" instead of "hooks.*".  (Editorial comment:
+  post-receive-email should never have used such a generic top-level
+  namespace.)
+
+* In emails about new annotated tags, post-receive-email includes a
+  shortlog of all changes since the previous annotated tag.  To get
+  this behavior with git-multimail, you need to set
+  multimailhook.announceshortlog to true:
+
+      git config multimailhook.announceshortlog true
+
+* multimailhook.commitlist -- This is a new configuration variable.
+  Recipients listed here will receive a separate email for each new
+  commit.  However, if this variable is *not* set, it defaults to the
+  value of multimailhook.mailinglist.  Therefore, if you *don't* want
+  the members of multimailhook.mailinglist to receive one email per
+  commit, then set this value to the empty string:
+
+      git config multimailhook.commitlist ''
+
+* multimailhook.emailprefix -- If this value is not set, then the
+  subjects of generated emails are prefixed with the short name of the
+  repository enclosed in square brackets; e.g., "[myrepo]".
+  post-receive-email defaults to prefix "[SCM]" if this option is not
+  set.  So if you were using the old default and want to retain it
+  (for example, to avoid having to change your email filters), set
+  this variable explicitly to the old value:
+
+      git config multimailhook.emailprefix "[SCM]"
+
+* The "multimailhook.showrev" configuration option is not supported.
+  Its main use is obsoleted by the one-email-per-commit feature of
+  git-multimail.
+
+
+Other differences
+=================
+
+This section describes other differences in the behavior of
+git-multimail vs. post-receive-email.  For full details, please refer
+to the main README file:
+
+* One email per commit.  For each reference change, the script first
+  outputs one email summarizing the reference change (including
+  one-line summaries of the new commits), then it outputs a separate
+  email for each new commit that was introduced, including patches.
+  These one-email-per-commit emails go to the addresses listed in
+  multimailhook.commitlist.  post-receive-email sends only one email
+  for each *reference* that is changed, no matter how many commits
+  were added to the reference.
+
+* Better algorithm for detecting new commits.  post-receive-email
+  processes one reference change at a time, which causes it to fail to
+  describe new commits that were included in multiple branches.  For
+  example, if a single push adds the "*" commits in the diagram below,
+  then post-receive-email would never include the details of the two
+  commits that are common to "master" and "branch" in its
+  notifications.
+
+      o---o---o---*---*---*    <-- master
+                       \
+                        *---*  <-- branch
+
+  git-multimail analyzes all reference modifications to determine
+  which commits were not present before the change, therefore avoiding
+  that error.
+
+* In reference change emails, git-multimail tells which commits have
+  been added to the reference vs. are entirely new to the repository,
+  and which commits that have been omitted from the reference
+  vs. entirely discarded from the repository.
+
+* The environment in which Git is running can be configured via an
+  "Environment" abstraction.
+
+* Built-in support for Gitolite-managed repositories.
+
+* Instead of using full SHA1 object names in emails, git-multimail
+  mostly uses abbreviated SHA1s, plus one-line log message summaries
+  where appropriate.
+
+* In the schematic diagrams that explain non-fast-forward commits,
+  git-multimail shows the names of the branches involved.
+
+* The emails generated by git-multimail include the name of the Git
+  repository that was modified; this is convenient for recipients who
+  are monitoring multiple repositories.
+
+* git-multimail allows the email "From" addresses to be configured.
+
+* The recipients lists (multimailhook.mailinglist,
+  multimailhook.refchangelist, multimailhook.announcelist, and
+  multimailhook.commitlist) can be comma-separated values and/or
+  multivalued settings in the config file; e.g.,
+
+      [multimailhook]
+              mailinglist = mr.brown@example.com, mr.black@example.com
+              announcelist = Him <him@example.com>
+              announcelist = Jim <jim@example.com>
+              announcelist = pop@example.com
+
+  This might make it easier to maintain short recipients lists without
+  requiring full-fledged mailing list software.
+
+* By default, git-multimail sets email "Reply-To" headers to reply to
+  the pusher (for reference updates) and to the author (for commit
+  notifications).  By default, the pusher's email address is
+  constructed by appending "multimailhook.emaildomain" to the pusher's
+  username.
+
+* The generated emails contain a configurable footer.  By default, it
+  lists the name of the administrator who should be contacted to
+  unsubscribe from notification emails.
+
+* New option multimailhook.emailmaxlinelength to limit the length of
+  lines in the main part of the email body.  The default limit is 500
+  characters.
+
+* New option multimailhook.emailstrictutf8 to ensure that the main
+  part of the email body is valid UTF-8.  Invalid characters are
+  turned into the Unicode replacement character, U+FFFD.  By default
+  this option is turned on.
+
+* Written in Python.  Easier to add new features.

+"""Generate notification emails for pushes to a git repository.
+
+This hook sends emails describing changes introduced by pushes to a
+git repository.  For each reference that was changed, it emits one
+ReferenceChange email summarizing how the reference was changed,
+followed by one Revision email for each new commit that was introduced
+by the reference change.
+
+Each commit is announced in exactly one Revision email.  If the same
+commit is merged into another branch in the same or a later push, then
+the ReferenceChange email will list the commit's SHA1 and its one-line
+summary, but no new Revision email will be generated.
+
+This script is designed to be used as a "post-receive" hook in a git
+repository (see githooks(5)).  It can also be used as an "update"
+script, but this usage is not completely reliable and is deprecated.
+
+To help with debugging, this script accepts a --stdout option, which
+causes the emails to be written to standard output rather than sent
+using sendmail.
+
+See the accompanying README file for the complete documentation.

+
+    * what user did the push
+
+    * what users want to be informed about various types of changes.
+
+    An Environment object is expected to have the following methods:
+
+        get_repo_shortname()
+
+            Return a short name for the repository, for display
+            purposes.
+
+        get_repo_path()
+
+            Return the absolute path to the Git repository.
+
+        get_emailprefix()
+
+            Return a string that will be prefixed to every email's
+            subject.
+
+        get_pusher()
+
+            Return the username of the person who pushed the changes.
+            This value is used in the email body to indicate who
+            pushed the change.
+
+        get_pusher_email() (may return None)
+
+            Return the email address of the person who pushed the
+            changes.  The value should be a single RFC 2822 email
+            address as a string; e.g., "Joe User <user@example.com>"
+            if available, otherwise "user@example.com".  If set, the
+            value is used as the Reply-To address for refchange
+            emails.  If it is impossible to determine the pusher's
+            email, this attribute should be set to None (in which case
+            no Reply-To header will be output).
+

+
+            Return the address to be used as the 'From' email address
+            in the email envelope.
+
+        get_fromaddr()
+
+            Return the 'From' email address used in the email 'From:'
+            headers.  (May be a full RFC 2822 email address like 'Joe
+            User <user@example.com>'.)
+
+        get_administrator()
+
+            Return the name and/or email of the repository
+            administrator.  This value is used in the footer as the
+            person to whom requests to be removed from the
+            notification list should be sent.  Ideally, it should
+            include a valid email address.
+
+        get_reply_to_refchange()
+        get_reply_to_commit()
+
+            Return the address to use in the email "Reply-To" header,
+            as a string.  These can be an RFC 2822 email address, or
+            None to omit the "Reply-To" header.
+            get_reply_to_refchange() is used for refchange emails;
+            get_reply_to_commit() is used for individual commit
+            emails.

+
+        announce_show_shortlog (bool)

+            True iff announce emails should include a shortlog.
+
+        refchange_showlog (bool)
+
+            True iff refchanges emails should include a detailed log.
+
+        diffopts (list of strings)
+
+            The options that should be passed to 'git diff' for the
+            summary email.  The value should be a list of strings
+            representing words to be passed to the command.
+
+        logopts (list of strings)
+
+            Analogous to diffopts, but contains options passed to
+            'git log' when generating the detailed log for a set of
+            commits (see refchange_showlog)
+
+        commitlogopts (list of strings)
+
+            The options that should be passed to 'git log' for each

+
+    It is easy to figure out what commits were added to a *branch* by
+    a Reference change:
+
+        git rev-list change.old..change.new
+
+    or removed from a *branch*:
+
+        git rev-list change.new..change.old
+
+    But it is not quite so trivial to determine which entirely new
+    commits were added to the *repository* by a push and which old
+    commits were discarded by a push.  A big part of the job of this
+    class is to figure out these things, and to make sure that new
+    commits are only detailed once even if they were added to multiple
+    references.
+
+    The first step is to determine the "other" references--those
+    unaffected by the current push.  They are computed by
+    Push._compute_other_ref_sha1s() by listing all references then
+    removing any affected by this push.
+
+    The commits contained in the repository before this push were
+
+        git rev-list other1 other2 other3 ... change1.old change2.old ...
+
+    Where "changeN.old" is the old value of one of the references
+    affected by this push.
+
+    The commits contained in the repository after this push are
+
+        git rev-list other1 other2 other3 ... change1.new change2.new ...
+
+    The commits added by this push are the difference between these
+    two sets, which can be written
+
+        git rev-list \
+            ^other1 ^other2 ... \
+            ^change1.old ^change2.old ... \
+            change1.new change2.new ...
+
+    The commits removed by this push can be computed by
+
+        git rev-list \
+            ^other1 ^other2 ... \
+            ^change1.new ^change2.new ... \
+            change1.old change2.old ...
+
+    The last point is that it is possible that other pushes are
+    occurring simultaneously to this one, so reference values can
+    change at any time.  It is impossible to eliminate all race
+    conditions, but we reduce the window of time during which problems
+    can occur by translating reference names to SHA1s as soon as
+    possible and working with SHA1s thereafter (because SHA1s are

+"""Example post-receive hook based on git-multimail.
+
+This script is a simple example of a post-receive hook implemented
+using git_multimail.py as a Python module.  It is intended to be
+customized before use; see the comments in the script to help you get
+started.
+
+It is possible to use git_multimail.py itself as a post-receive or
+update hook, configured via git config settings and/or command-line
+parameters.  But for more flexibility, it can also be imported as a
+Python module by a custom post-receive script as done here.  The
+latter has the following advantages:
+
+* The tool's behavior can be customized using arbitrary Python code,
+  without having to edit git_multimail.py.
+
+* Configuration settings can be read from other sources; for example,
+  user names and email addresses could be read from LDAP or from a
+  database.  Or the settings can even be hardcoded in the importing
+  Python script, if this is preferred.
+
+This script is a very basic example of how to use git_multimail.py as
+a module.  The comments below explain some of the points at which the
+script's behavior could be changed or customized.

+DESCRIPTION:
+Preview is an utiliy to preview local content of a mediawiki repo as if it was
+pushed on the remote.
+
+For that, preview searches for the remote name of the current branch's
+upstream if --remote is not set. If that remote is not found or if it
+is not a mediawiki, it lists all mediawiki remotes configured and asks
+you to replay your command with the --remote option set properly.
+
+Then, it searches for a file named 'filename'. If it's not found in
+the current dir, it will assume it's a blob.
+
+The content retrieved in the file (or in the blob) will then be parsed
+by the remote mediawiki and combined with a template retrieved from
+the mediawiki.
+
+Finally, preview will save the HTML result in a file. and autoload it
+in your default web browser if the option --autoload is present.

+Tests for Mediawiki-to-Git
+==========================
+
+Introduction
+------------
+This manual describes how to install the git-remote-mediawiki test
+environment on a machine with git installed on it.
+
+Prerequisite
+------------
+
+In order to run this test environment correctly, you will need to
+install the following packages (Debian/Ubuntu names, may need to be
+adapted for another distribution):
+
+* lighttpd
+* php5
+* php5-cgi
+* php5-cli
+* php5-curl
+* php5-sqlite
+
+Principles and Technical Choices
+--------------------------------
+
+The test environment makes it easy to install and manipulate one or
+several MediaWiki instances. To allow developers to run the testsuite
+easily, the environment does not require root privilege (except to
+install the required packages if needed). It starts a webserver
+instance on the user's account (using lighttpd greatly helps for
+that), and does not need a separate database daemon (thanks to the use
+of sqlite).
+
+Run the test environment
+------------------------
+
+Install a new wiki
+~~~~~~~~~~~~~~~~~~
+
+Once you have all the prerequisite, you need to install a MediaWiki
+instance on your machine. If you already have one, it is still
+strongly recommended to install one with the script provided. Here's
+how to work it:
+
+a. change directory to contrib/mw-to-git/t/
+b. if needed, edit test.config to choose your installation parameters
+c. run `./install-wiki.sh install`
+d. check on your favourite web browser if your wiki is correctly
+   installed.
+
+Remove an existing wiki
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Edit the file test.config to fit the wiki you want to delete, and then
+execute the command `./install-wiki.sh delete` from the
+contrib/mw-to-git/t directory.
+
+Run the existing tests
+~~~~~~~~~~~~~~~~~~~~~~
+
+The provided tests are currently in the `contrib/mw-to-git/t` directory.
+The files are all the t936[0-9]-*.sh shell scripts.
+
+a. Run all tests:
+To do so, run "make test" from the contrib/mw-to-git/ directory.
+
+b. Run a specific test:
+To run a given test <test_name>, run ./<test_name> from the
+contrib/mw-to-git/t directory.
+
+How to create new tests
+-----------------------
+
+Available functions
+~~~~~~~~~~~~~~~~~~~
+
+The test environment of git-remote-mediawiki provides some functions
+useful to test its behaviour. for more details about the functions'
+parameters, please refer to the `test-gitmw-lib.sh` and
+`test-gitmw.pl` files.
+
+** `test_check_wiki_precond`:
+Check if the tests must be skipped or not. Please use this function
+at the beginning of each new test file.
+
+** `wiki_getpage`:
+Fetch a given page from the wiki and puts its content in the
+directory in parameter.
+
+** `wiki_delete_page`:
+Delete a given page from the wiki.
+
+** `wiki_edit_page`:
+Create or modify a given page in the wiki. You can specify several
+parameters like a summary for the page edition, or add the page to a
+given category.
+See test-gitmw.pl for more details.
+
+** `wiki_getallpage`:
+Fetch all pages from the wiki into a given directory. The directory
+is created if it does not exists.
+
+** `test_diff_directories`:
+Compare the content of two directories. The content must be the same.
+Use this function to compare the content of a git directory and a wiki
+one created by wiki_getallpage.
+
+** `test_contains_N_files`:
+Check if the given directory contains a given number of file.
+
+** `wiki_page_exists`:
+Tests if a given page exists on the wiki.
+
+** `wiki_reset`:
+Reset the wiki, i.e. flush the database. Use this function at the
+beginning of each new test, except if the test re-uses the same wiki
+(and history) as the previous test.
+
+How to write a new test
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Please, follow the standards given by git. See git/t/README.
+New file should be named as t936[0-9]-*.sh.
+Be sure to reset your wiki regulary with the function `wiki_reset`.

-NAME
-----
-git-p4import - Import a Perforce repository into git
-
-
-SYNOPSIS
---------
-[verse]
-`git-p4import` [-q|-v] [--notags] [--authors <file>] [-t <timezone>]
-               <//p4repo/path> <branch>
-`git-p4import` --stitch <//p4repo/path>
-`git-p4import`
-
-
-DESCRIPTION
------------
-Import a Perforce repository into an existing git repository.  When
-a <//p4repo/path> and <branch> are specified a new branch with the
-given name will be created and the initial import will begin.
-
-Once the initial import is complete you can do an incremental import
-of new commits from the Perforce repository.  You do this by checking
-out the appropriate git branch and then running `git-p4import` without
-any options.
-
-The standard p4 client is used to communicate with the Perforce
-repository; it must be configured correctly in order for `git-p4import`
-to operate (see below).
-
-
-OPTIONS
--------
--q::
-	Do not display any progress information.
-
--v::
-        Give extra progress information.
-
-\--authors::
-	Specify an authors file containing a mapping of Perforce user
-	ids to full names and email addresses (see Notes below).
-
-\--notags::
-	Do not create a tag for each imported commit.
-
-\--stitch::
-	Import the contents of the given perforce branch into the
-	currently checked out git branch.
-
-\--log::
-	Store debugging information in the specified file.
-
--t::
-	Specify that the remote repository is in the specified timezone.
-	Timezone must be in the format "US/Pacific" or "Europe/London"
-	etc.  You only need to specify this once, it will be saved in
-	the git config file for the repository.
-
-<//p4repo/path>::
-	The Perforce path that will be imported into the specified branch.
-
-<branch>::
-	The new branch that will be created to hold the Perforce imports.
-
-
-P4 Client
----------
-You must make the `p4` client command available in your $PATH and
-configure it to communicate with the target Perforce repository.
-Typically this means you must set the "$P4PORT" and "$P4CLIENT"
-environment variables.
-
-You must also configure a `p4` client "view" which maps the Perforce
-branch into the top level of your git repository, for example:
-
-------------
-Client: myhost
-
-Root:   /home/sean/import
-
-Options:   noallwrite clobber nocompress unlocked modtime rmdir
-
-View:
-        //public/jam/... //myhost/jam/...
-------------
-
-With the above `p4` client setup, you could import the "jam"
-perforce branch into a branch named "jammy", like so:
-
-------------
-$ mkdir -p /home/sean/import/jam
-$ cd /home/sean/import/jam
-$ git init
-$ git p4import //public/jam jammy
-------------
-
-
-Multiple Branches
------------------
-Note that by creating multiple "views" you can use `git-p4import`
-to import additional branches into the same git repository.
-However, the `p4` client has a limitation in that it silently
-ignores all but the last "view" that maps into the same local
-directory.  So the following will *not* work:
-
-------------
-View:
-        //public/jam/... //myhost/jam/...
-        //public/other/... //myhost/jam/...
-        //public/guest/... //myhost/jam/...
-------------
-
-If you want more than one Perforce branch to be imported into the
-same directory you must employ a workaround.  A simple option is
-to adjust your `p4` client before each import to only include a
-single view.
-
-Another option is to create multiple symlinks locally which all
-point to the same directory in your git repository and then use
-one per "view" instead of listing the actual directory.
-
-
-Tags
-----
-A git tag of the form p4/xx is created for every change imported from
-the Perforce repository where xx is the Perforce changeset number.
-Therefore after the import you can use git to access any commit by its
-Perforce number, e.g. git show p4/327.
-
-The tag associated with the HEAD commit is also how `git-p4import`
-determines if there are new changes to incrementally import from the
-Perforce repository.
-
-If you import from a repository with many thousands of changes
-you will have an equal number of p4/xxxx git tags.  Git tags can
-be expensive in terms of disk space and repository operations.
-If you don't need to perform further incremental imports, you
-may delete the tags.
-
-
-Notes
------
-You can interrupt the import (e.g. ctrl-c) at any time and restart it
-without worry.
-
-Author information is automatically determined by querying the
-Perforce "users" table using the id associated with each change.
-However, if you want to manually supply these mappings you can do
-so with the "--authors" option.  It accepts a file containing a list
-of mappings with each line containing one mapping in the format:
-
-------------
-    perforce_id = Full Name <email@address.com>

+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,

+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+git-remote-persistent-https
+
+The git-remote-persistent-https binary speeds up SSL operations
+by running a daemon job (git-remote-persistent-https--proxy) that
+keeps a connection open to a server.
+
+
+PRE-BUILT BINARIES
+
+Darwin amd64:
+https://commondatastorage.googleapis.com/git-remote-persistent-https/darwin_amd64.tar.gz
+
+Linux amd64:
+https://commondatastorage.googleapis.com/git-remote-persistent-https/linux_amd64.tar.gz
+
+
+INSTALLING
+
+Move all of the git-remote-persistent-http* binaries to a directory
+in PATH.
+
+
+USAGE
+
+HTTPS requests can be delegated to the proxy by using the
+"persistent-https" scheme, e.g.
+
+git clone persistent-https://kernel.googlesource.com/pub/scm/git/git
+
+Likewise, .gitconfig can be updated as follows to rewrite https urls
+to use persistent-https:
+
+[url "persistent-https"]
+	insteadof = https
+[url "persistent-http"]
+	insteadof = http
+
+
+#####################################################################
+# BUILDING FROM SOURCE
+#####################################################################
+
+LOCATION
+
+The source is available in the contrib/persistent-https directory of
+the Git source repository. The Git source repository is available at
+git://git.kernel.org/pub/scm/git/git.git/
+https://kernel.googlesource.com/pub/scm/git/git
+
+
+PREREQUISITES
+
+The code is written in Go (http://golang.org/) and the Go compiler is
+required. Currently, the compiler must be built and installed from tip
+of source, in order to include a fix in the reverse http proxy:
+http://code.google.com/p/go/source/detail?r=a615b796570a2cd8591884767a7d67ede74f6648
+
+
+BUILDING
+
+Run "make" to build the binaries. See the section on
+INSTALLING above.

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.

+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+HOW TO INSTALL git-subtree
+==========================
+
+First, build from the top source directory.
+
+Then, in contrib/subtree, run:
+
+  make
+  make install
+  make install-doc
+
+If you used configure to do the main build the git-subtree build will
+pick up those settings.  If not, you will likely have to provide a
+value for prefix:
+
+  make prefix=<some dir>
+  make prefix=<some dir> install
+  make prefix=<some dir> install-doc
+
+To run tests first copy git-subtree to the main build area so the
+newly-built git can find it:
+
+  cp git-subtree ../..
+
+Then:
+
+  make test

+'git subtree' add   -P <prefix> <repository> <ref>
+'git subtree' pull  -P <prefix> <repository> <ref>

+
+
+DESCRIPTION
+-----------
+Subtrees allow subprojects to be included within a subdirectory
+of the main project, optionally including the subproject's
+entire history.
+
+For example, you could include the source code for a library
+as a subdirectory of your application.
+
+Subtrees are not to be confused with submodules, which are meant for
+the same task. Unlike submodules, subtrees do not need any special
+constructions (like .gitmodule files or gitlinks) be present in
+your repository, and do not force end-users of your
+repository to do anything special or to understand how subtrees
+work. A subtree is just a subdirectory that can be
+committed to, branched, and merged along with your project in
+any way you want.
+
+They are also not to be confused with using the subtree merge
+strategy. The main difference is that, besides merging
+the other project as a subdirectory, you can also extract the
+entire history of a subdirectory from your project and make it
+into a standalone project. Unlike the subtree merge strategy
+you can alternate back and forth between these
+two operations. If the standalone library gets updated, you can
+automatically merge the changes into your project; if you
+update the library inside your project, you can "split" the
+changes back out again and merge them back into the library
+project.
+
+For example, if a library you made for one application ends up being
+useful elsewhere, you can extract its entire history and publish
+that as its own git repository, without accidentally
+intermingling the history of your application project.
+
+[TIP]
+In order to keep your commit messages clean, we recommend that
+people split their commits between the subtrees and the main
+project as much as possible.  That is, if you make a change that
+affects both the library and the main application, commit it in
+two pieces.  That way, when you split the library commits out
+later, their descriptions will still make sense.  But if this
+isn't important to you, it's not *necessary*.  git subtree will
+simply leave out the non-library-related parts of the commit
+when it splits it out into the subproject later.
+
+
+COMMANDS
+--------
+add::
+	Create the <prefix> subtree by importing its contents
+	from the given <commit> or <repository> and remote <ref>.
+	A new commit is created	automatically, joining the imported
+	project's history with your own.  With '--squash', imports
+	only a single commit from the subproject, rather than its
+	entire history.
+
+merge::
+	Merge recent changes up to <commit> into the <prefix>
+	subtree.  As with normal 'git merge', this doesn't
+	remove your own local changes; it just merges those
+	changes into the latest <commit>.  With '--squash',
+	creates only one commit that contains all the changes,
+	rather than merging in the entire history.
++
+If you use '--squash', the merge direction doesn't always have to be
+forward; you can use this command to go back in time from v2.5 to v2.4,
+for example.  If your merge introduces a conflict, you can resolve it in
+the usual ways.
+	
+pull::
+	Exactly like 'merge', but parallels 'git pull' in that
+	it fetches the given ref from the specified remote
+	repository.
+	
+push::
+	Does a 'split' (see below) using the <prefix> supplied
+	and then does a 'git push' to push the result to the 
+	repository and ref. This can be used to push your
+	subtree to different branches of the remote repository.
+
+split::
+	Extract a new, synthetic project history from the
+	history of the <prefix> subtree.  The new history
+	includes only the commits (including merges) that
+	affected <prefix>, and each of those commits now has the
+	contents of <prefix> at the root of the project instead
+	of in a subdirectory.  Thus, the newly created history
+	is suitable for export as a separate git repository.
++
+After splitting successfully, a single commit id is printed to stdout.
+This corresponds to the HEAD of the newly created tree, which you can
+manipulate however you want.
++
+Repeated splits of exactly the same history are guaranteed to be
+identical (i.e. to produce the same commit ids).  Because of this, if
+you add new commits and then re-split, the new commits will be attached
+as commits on top of the history you generated last time, so 'git merge'
+and friends will work as expected.
++
+Note that if you use '--squash' when you merge, you should usually not
+just '--rejoin' when you split.
+
+
+OPTIONS
+-------
+-q::
+--quiet::
+	Suppress unnecessary output messages on stderr.
+
+-d::
+--debug::
+	Produce even more unnecessary output messages on stderr.
+
+-P <prefix>::
+--prefix=<prefix>::
+	Specify the path in the repository to the subtree you
+	want to manipulate.  This option is mandatory
+	for all commands.
+
+-m <message>::
+--message=<message>::
+	This option is only valid for add, merge and pull (unsure).
+	Specify <message> as the commit message for the merge commit.
+
+
+OPTIONS FOR add, merge, push, pull
+----------------------------------
+--squash::
+	This option is only valid for add, merge, push and pull
+	commands.
++
+Instead of merging the entire history from the subtree project, produce
+only a single commit that contains all the differences you want to
+merge, and then merge that new commit into your project.
++
+Using this option helps to reduce log clutter. People rarely want to see
+every change that happened between v1.0 and v1.1 of the library they're
+using, since none of the interim versions were ever included in their
+application.
++
+Using '--squash' also helps avoid problems when the same subproject is
+included multiple times in the same project, or is removed and then
+re-added.  In such a case, it doesn't make sense to combine the
+histories anyway, since it's unclear which part of the history belongs
+to which subtree.
++
+Furthermore, with '--squash', you can switch back and forth between
+different versions of a subtree, rather than strictly forward.  'git
+subtree merge --squash' always adjusts the subtree to match the exactly
+specified commit, even if getting to that commit would require undoing
+some changes that were added earlier.
++
+Whether or not you use '--squash', changes made in your local repository
+remain intact and can be later split and send upstream to the
+subproject.
+
+
+OPTIONS FOR split
+-----------------
+--annotate=<annotation>::
+	This option is only valid for the split command.
++
+When generating synthetic history, add <annotation> as a prefix to each
+commit message.  Since we're creating new commits with the same commit
+message, but possibly different content, from the original commits, this
+can help to differentiate them and avoid confusion.
++
+Whenever you split, you need to use the same <annotation>, or else you
+don't have a guarantee that the new re-created history will be identical
+to the old one.  That will prevent merging from working correctly.  git
+subtree tries to make it work anyway, particularly if you use --rejoin,
+but it may not always be effective.
+
+-b <branch>::
+--branch=<branch>::
+	This option is only valid for the split command.
++
+After generating the synthetic history, create a new branch called
+<branch> that contains the new history.  This is suitable for immediate
+pushing upstream.  <branch> must not already exist.
+
+--ignore-joins::
+	This option is only valid for the split command.
++
+If you use '--rejoin', git subtree attempts to optimize its history
+reconstruction to generate only the new commits since the last
+'--rejoin'.  '--ignore-join' disables this behaviour, forcing it to
+regenerate the entire history.  In a large project, this can take a long
+time.
+
+--onto=<onto>::
+	This option is only valid for the split command.
++
+If your subtree was originally imported using something other than git
+subtree, its history may not match what git subtree is expecting.  In
+that case, you can specify the commit id <onto> that corresponds to the
+first revision of the subproject's history that was imported into your
+project, and git subtree will attempt to build its history from there.
++
+If you used 'git subtree add', you should never need this option.
+
+--rejoin::
+	This option is only valid for the split command.
++
+After splitting, merge the newly created synthetic history back into
+your main project.  That way, future splits can search only the part of
+history that has been added since the most recent --rejoin.
++
+If your split commits end up merged into the upstream subproject, and
+then you want to get the latest upstream version, this will allow git's
+merge algorithm to more intelligently avoid conflicts (since it knows
+these synthetic commits are already part of the upstream repository).
++
+Unfortunately, using this option results in 'git log' showing an extra
+copy of every new commit that was created (the original, and the
+synthetic one).
++
+If you do all your merges with '--squash', don't use '--rejoin' when you
+split, because you don't want the subproject's history to be part of
+your project anyway.
+
+
+EXAMPLE 1. Add command
+----------------------
+Let's assume that you have a local repository that you would like
+to add an external vendor library to. In this case we will add the
+git-subtree repository as a subdirectory of your already existing
+git-extensions repository in ~/git-extensions/:
+
+	$ git subtree add --prefix=git-subtree --squash \
+		git://github.com/apenwarr/git-subtree.git master
+
+'master' needs to be a valid remote ref and can be a different branch
+name
+
+You can omit the --squash flag, but doing so will increase the number
+of commits that are included in your local repository.
+
+We now have a ~/git-extensions/git-subtree directory containing code
+from the master branch of git://github.com/apenwarr/git-subtree.git
+in our git-extensions repository.
+
+EXAMPLE 2. Extract a subtree using commit, merge and pull
+---------------------------------------------------------
+Let's use the repository for the git source code as an example.
+First, get your own copy of the git.git repository:
+
+	$ git clone git://git.kernel.org/pub/scm/git/git.git test-git
+	$ cd test-git
+
+gitweb (commit 1130ef3) was merged into git as of commit
+0a8f4f0, after which it was no longer maintained separately. 
+But imagine it had been maintained separately, and we wanted to
+extract git's changes to gitweb since that time, to share with
+the upstream.  You could do this:
+
+	$ git subtree split --prefix=gitweb --annotate='(split) ' \
+        	0a8f4f0^.. --onto=1130ef3 --rejoin \
+        	--branch gitweb-latest
+        $ gitk gitweb-latest
+        $ git push git@github.com:whatever/gitweb.git gitweb-latest:master
+        
+(We use '0a8f4f0^..' because that means "all the changes from
+0a8f4f0 to the current version, including 0a8f4f0 itself.")
+
+If gitweb had originally been merged using 'git subtree add' (or
+a previous split had already been done with --rejoin specified)
+then you can do all your splits without having to remember any
+weird commit ids:
+
+	$ git subtree split --prefix=gitweb --annotate='(split) ' --rejoin \
+		--branch gitweb-latest2
+
+And you can merge changes back in from the upstream project just
+as easily:
+
+	$ git subtree pull --prefix=gitweb \
+		git@github.com:whatever/gitweb.git master
+
+Or, using '--squash', you can actually rewind to an earlier
+version of gitweb:
+
+	$ git subtree merge --prefix=gitweb --squash gitweb-latest~10
+
+Then make some changes:
+
+	$ date >gitweb/myfile
+	$ git add gitweb/myfile
+	$ git commit -m 'created myfile'
+
+And fast forward again:
+
+	$ git subtree merge --prefix=gitweb --squash gitweb-latest
+
+And notice that your change is still intact:
+	
+	$ ls -l gitweb/myfile
+
+And you can split it out and look at your changes versus
+the standard gitweb:
+
+	git log gitweb-latest..$(git subtree split --prefix=gitweb)
+
+EXAMPLE 3. Extract a subtree using branch
+-----------------------------------------
+Suppose you have a source directory with many files and
+subdirectories, and you want to extract the lib directory to its own
+git project. Here's a short way to do it:
+
+First, make the new repository wherever you want:
+
+	$ <go to the new location>
+	$ git init --bare
+
+Back in your original directory:
+
+	$ git subtree split --prefix=lib --annotate="(split)" -b split
+
+Then push the new branch onto the new empty repository:
+
+	$ git push <new-repo> split:master

+		specified... that's just an optimization
+
+	if you try to add (or maybe merge?) with an invalid commitid, you
+		get a misleading "prefix must end with /" message from
+		one of the other git tools that git-subtree calls.  Should
+		detect this situation and print the *real* problem.
+	
+	"pull --squash" should do fetch-synthesize-merge, but instead just
+		does "pull" directly, which doesn't work at all.
+
+	make a 'force-update' that does what 'add' does even if the subtree
+		already exists.  That way we can help people who imported
+		subtrees "incorrectly" (eg. by just copying in the files) in
+		the past.
+
+	guess --prefix automatically if possible based on pwd
+
+	make a 'git subtree grafts' that automatically expands --squash'd
+		commits so you can see the full history if you want it.

+=========
+
+NAME
+----
+svn-fe - convert an SVN "dumpfile" to a fast-import stream
+
+SYNOPSIS
+--------
+[verse]
+mkfifo backchannel &&
+svnadmin dump --deltas REPO |
+	svn-fe [url] 3<backchannel |
+	git fast-import --cat-blob-fd=3 3>backchannel
+
+DESCRIPTION
+-----------
+
+Converts a Subversion dumpfile into input suitable for
+git-fast-import(1) and similar importers. REPO is a path to a
+Subversion repository mirrored on the local disk. Remote Subversion
+repositories can be mirrored on local disk using the `svnsync`
+command.
+
+Note: this tool is very young.  The details of its commandline
+interface may change in backward incompatible ways.
+
+INPUT FORMAT
+------------
+Subversion's repository dump format is documented in full in
+`notes/dump-load-format.txt` from the Subversion source tree.
+Files in this format can be generated using the 'svnadmin dump' or
+'svk admin dump' command.
+
+OUTPUT FORMAT
+-------------
+The fast-import format is documented by the git-fast-import(1)
+manual page.
+
+NOTES
+-----
+Subversion dumps do not record a separate author and committer for
+each revision, nor do they record a separate display name and email
+address for each author.  Like git-svn(1), 'svn-fe' will use the name
+
+---------
+user <user@UUID>
+---------
+
+as committer, where 'user' is the value of the `svn:author` property
+and 'UUID' the repository's identifier.
+
+To support incremental imports, 'svn-fe' puts a `git-svn-id` line at
+the end of each commit log message if passed a URL on the command
+line.  This line has the form `git-svn-id: URL@REVNO UUID`.
+
+The resulting repository will generally require further processing
+to put each project in its own repository and to separate the history
+of each branch.  The 'git filter-branch --subdirectory-filter' command
+may be useful for this purpose.
+
+BUGS
+----
+Empty directories and unknown properties are silently discarded.
+
+The exit status does not reflect whether an error was detected.

+	   This trick arranges for messages to be emitted in the user's
+	   requested encoding, but avoids setting LC_CTYPE from the
+	   environment for the whole program.
+
+	   This primarily done to avoid a bug in vsnprintf in the GNU C
+	   Library [1]. which triggered a "your vsnprintf is broken" error
+	   on Git's own repository when inspecting v0.99.6~1 under a UTF-8
+	   locale.
+
+	   That commit contains a ISO-8859-1 encoded author name, which
+	   the locale aware vsnprintf(3) won't interpolate in the format
+	   argument, due to mismatch between the data encoding and the
+	   locale.
+
+	   Even if it wasn't for that bug we wouldn't want to use LC_CTYPE at
+	   this point, because it'd require auditing all the code that uses C
+	   functions whose semantics are modified by LC_CTYPE.
+
+	   But only setting LC_MESSAGES as we do creates a problem, since
+	   we declare the encoding of our PO files[2] the gettext
+	   implementation will try to recode it to the user's locale, but
+	   without LC_CTYPE it'll emit something like this on 'git init'
+	   under the Icelandic locale:
+
+	       Bj? til t?ma Git lind ? /hlagh/.git/
+
+	   Gettext knows about the encoding of our PO file, but we haven't
+	   told it about the user's encoding, so all the non-US-ASCII
+	   characters get encoded to question marks.
+
+	   But we're in luck! We can set LC_CTYPE from the environment
+	   only while we call nl_langinfo and
+	   bind_textdomain_codeset. That suffices to tell gettext what
+	   encoding it should emit in, so it'll now say:
+
+	       Bjó til tóma Git lind í /hlagh/.git/
+
+	   And the equivalent ISO-8859-1 string will be emitted under a
+	   ISO-8859-1 locale.
+
+	   With this change way we get the advantages of setting LC_CTYPE
+	   (talk to the user in his language/encoding), without the major
+	   drawbacks (changed semantics for C functions we rely on).
+
+	   However foreign functions using other message catalogs that
+	   aren't using our neat trick will still have a problem, e.g. if
+	   we have to call perror(3):
+
+	   #include <stdio.h>
+	   #include <locale.h>
+	   #include <errno.h>
+
+	   int main(void)
+	   {
+		   setlocale(LC_MESSAGES, "");
+		   setlocale(LC_CTYPE, "C");
+		   errno = ENODEV;
+		   perror("test");
+		   return 0;
+	   }
+
+	   Running that will give you a message with question marks:
+
+	   $ LANGUAGE= LANG=de_DE.utf8 ./test
+	   test: Kein passendes Ger?t gefunden
+
+	   The vsnprintf bug has been fixed since glibc 2.17.
+
+	   Then we could simply set LC_CTYPE from the environment, which would
+	   make things like the external perror(3) messages work.
+
+	   See t/t0203-gettext-setlocale-sanity.sh's "gettext.c" tests for
+	   regression tests.
+
+	   1. http://sourceware.org/bugzilla/show_bug.cgi?id=6530

+    #   - Result of "cvs checkin -r" (possible, but not really
+    #     recommended): "2.1", "2.2", etc
+    #   - Branch tag: "1.2.0.n", where "1.2" is revision it was branched
+    #     from, "0" is a magic placeholder that identifies it as a
+    #     branch tag instead of a version tag, and n is 2 times the
+    #     branch number off of "1.2", starting with "2".
+    #   - Version on a branch: "1.2.n.x", where "1.2" is branch-from, "n"
+    #     is branch number off of "1.2" (like n above), and "x" is
+    #     the version number on the branch.
+    #   - Branches can branch off of branches: "1.3.2.7.4.1" (even number
+    #     of components).
+    #   - Odd "n"s are used by "vendor branches" that result
+    #     from "cvs import".  Vendor branches have additional
+    #     strangeness in the sense that the main rcs "head" of the main
+    #     branch will (temporarily until first normal commit) point
+    #     to the version on the vendor branch, rather than the actual
+    #     main branch.  (FUTURE: This may provide an opportunity
+    #     to use "strange" revision numbers for fast-forward-merged
+    #     branch tip when CVS client is asking for the main branch.)
+    #
+    # git-cvsserver CVS-compatible special numbering schemes:
+    #   - Currently git-cvsserver only tries to be identical to CVS for
+    #     simple "1.x" numbers on the "main" branch (as identified
+    #     by the module name that was originally cvs checkout'ed).
+    #   - The database only stores the "x" part, for historical reasons.
+    #     But most of the rest of the cvsserver preserves
+    #     and thinks using the full revision number.
+    #   - To handle non-linear history, it uses a version of the form
+    #     "2.1.1.2000.b.b.b."..., where the 2.1.1.2000 is to help uniquely
+    #     identify this as a special revision number, and there are
+    #     20 b's that together encode the sha1 git commit from which
+    #     this version of this file originated.  Each b is
+    #     the numerical value of the corresponding byte plus
+    #     100.
+    #      - "plus 100" avoids "0"s, and also reduces the
+    #        likelihood of a collision in the case that someone someday
+    #        writes an import tool that tries to preserve original
+    #        CVS revision numbers, and the original CVS data had done
+    #        lots of branches off of branches and other strangeness to
+    #        end up with a real version number that just happens to look
+    #        like this special revision number form.  Also, if needed
+    #        there are several ways to extend/identify alternative encodings
+    #        within the "2.1.1.2000" part if necessary.
+    #      - Unlike real CVS revisions, you can't really reconstruct what
+    #        relation a revision of this form has to other revisions.

-# SHORT DESCRIPTION
-#
-# This script makes it easy to fix up commits in the middle of a series,
-# and rearrange commits.
 #
 # The original idea comes from Eric W. Biederman, in
 # http://article.gmane.org/gmane.comp.version-control.git/22407
+#
+# The file containing rebase commands, comments, and empty lines.
+# This file is created by "git rebase -i" then edited by the user.  As
+# the lines are processed, they are removed from the front of this
+# file and written to the tail of $done.
+todo="$state_dir"/git-rebase-todo
+
+# The rebase command lines that have already been processed.  A line
+# is moved here when it is first handled, before any associated user
+# actions.
+done="$state_dir"/done
+
+# The commit message that is planned to be used for any changes that
+# need to be committed following a user interaction.
+msg="$state_dir"/message
+
+# The file into which is accumulated the suggested commit message for
+# squash/fixup commands.  When the first of a series of squash/fixups
+# is seen, the file is created and the commit message from the
+# previous commit and from the first squash/fixup commit are written
+# to it.  The commit message for each subsequent squash/fixup commit
+# is appended to the file as it is processed.
+#
+# The first line of the file is of the form
+#     # This is a combination of $count commits.
+# where $count is the number of commits whose messages have been
+# written to the file so far (including the initial "pick" commit).
+# Each time that a commit message is processed, this line is read and
+# updated.  It is deleted just before the combined commit is made.
+squash_msg="$state_dir"/message-squash
+
+# If the current series of squash/fixups has not yet included a squash
+# command, then this file exists and holds the commit message of the
+# original "pick" commit.  (If the series ends without a "squash"
+# command, then this can be used as the commit message of the combined
+# commit without opening the editor.)
+fixup_msg="$state_dir"/message-fixup
+
+# $rewritten is the name of a directory containing files for each
+# commit that is reachable by at least one merge base of $head and
+# $upstream. They are not necessarily rewritten, but their children
+# might be.  This ensures that commits on merged, but otherwise
+# unrelated side branches are left alone. (Think "X" in the man page's
+# example.)

+# A script to set the GIT_AUTHOR_NAME, GIT_AUTHOR_EMAIL, and
+# GIT_AUTHOR_DATE that will be used for the commit that is currently
+# being rebased.
+author_script="$state_dir"/author-script
+
+# When an "edit" rebase command is being processed, the SHA1 of the
+# commit to be edited is recorded in this file.  When "git rebase
+# --continue" is executed, if there are any staged changes then they
+# will be amended to the HEAD commit, but only provided the HEAD
+# commit is still the commit to be edited.  When any other rebase
+# command is processed, this file is deleted.
+amend="$state_dir"/amend
+
+# For the post-rewrite hook, we make a list of rewritten commits and
+# their new sha1s.  The rewritten-pending list keeps the sha1s of
+# commits that have been processed, but not committed yet,
+# e.g. because they are waiting for a 'squash' command.

-USAGE='[--interactive | -i] [-v] [--force-rebase | -f] [--onto <newbase>] [<upstream>|--root] [<branch>] [--quiet | -q]'
-LONG_USAGE='git-rebase replaces <branch> with a new branch of the
-same name.  When the --onto option is provided the new branch starts
-out with a HEAD equal to <newbase>, otherwise it is equal to <upstream>
-It then attempts to create a new commit for each commit from the original
-<branch> that does not exist in the <upstream> branch.
-
-It is possible that a merge failure will prevent this process from being
-completely automatic.  You will have to resolve any such merge failure
-and run git rebase --continue.  Another option is to bypass the commit
-that caused the merge failure with git rebase --skip.  To restore the
-original <branch> and remove the .git/rebase-apply working files, use the
-command git rebase --abort instead.
-
-Note that if <branch> is not specified on the command line, the
-currently checked out branch is used.
-
-Example:       git-rebase master~1 topic
-
-        A---B---C topic                   A'\''--B'\''--C'\'' topic
-       /                   -->           /

-# rev_map:

-# modules, but I'm not sure which is most portable...
-#
-# This is the replacement for the rev_db format, which was too big
-# and inefficient for large repositories with a lot of sparse history
-# (mainly tags)
-#
-# The format is this:
-#   - 24 bytes for every record,
-#     * 4 bytes for the integer representing an SVN revision number
-#     * 20 bytes representing the sha1 of a git commit
-#   - No empty padding records like the old format
-#     (except the last record, which can be overwritten)
-#   - new records are written append-only since SVN revision numbers
-#     increase monotonically
-#   - lookups on SVN revision number are done via a binary search
-#   - Piping the file to xxd -c24 is a good way of dumping it for
-#     viewing or editing (piped back through xxd -r), should the need
-#     ever arise.
-#   - The last record can be padding revision with an all-zero sha1
-#     This is used to optimize fetch performance when using multiple
-#     "fetch" directives in .git/config
-#

+
+How to configure gitweb for your local system
+---------------------------------------------
+
+You can specify the following configuration variables when building GIT:
+
+ * GIT_BINDIR
+   Points where to find the git executable.  You should set it up to
+   the place where the git binary was installed (usually /usr/bin) if you
+   don't install git from sources together with gitweb.  [Default: $(bindir)]
+ * GITWEB_SITENAME
+   Shown in the title of all generated pages, defaults to the server name
+   (SERVER_NAME CGI environment variable) if not set. [No default]
+ * GITWEB_PROJECTROOT
+   The root directory for all projects shown by gitweb. Must be set
+   correctly for gitweb to find repositories to display.  See also
+   "Gitweb repositories" in the INSTALL file for gitweb.  [Default: /pub/git]
+ * GITWEB_PROJECT_MAXDEPTH
+   The filesystem traversing limit for getting the project list; the number
+   is taken as depth relative to the projectroot.  It is used when
+   GITWEB_LIST is a directory (or is not set; then project root is used).
+   This is meant to speed up project listing on large work trees by limiting
+   search depth.  [Default: 2007]
+ * GITWEB_LIST
+   Points to a directory to scan for projects (defaults to project root
+   if not set / if empty) or to a file with explicit listing of projects
+   (together with projects' ownership). See "Generating projects list
+   using gitweb" in INSTALL file for gitweb to find out how to generate
+   such file from scan of a directory. [No default, which means use root
+   directory for projects]
+ * GITWEB_EXPORT_OK
+   Show repository only if this file exists (in repository).  Only
+   effective if this variable evaluates to true.  [No default / Not set]
+ * GITWEB_STRICT_EXPORT
+   Only allow viewing of repositories also shown on the overview page.
+   This for example makes GITWEB_EXPORT_OK to decide if repository is
+   available and not only if it is shown.  If GITWEB_LIST points to
+   file with list of project, only those repositories listed would be
+   available for gitweb.  [No default]
+ * GITWEB_HOMETEXT
+   Points to an .html file which is included on the gitweb project
+   overview page ('projects_list' view), if it exists.  Relative to
+   gitweb.cgi script.  [Default: indextext.html]
+ * GITWEB_SITE_HTML_HEAD_STRING
+   html snippet to include in the <head> section of each page. [No default]
+ * GITWEB_SITE_HEADER
+   Filename of html text to include at top of each page.  Relative to
+   gitweb.cgi script.  [No default]
+ * GITWEB_SITE_FOOTER
+   Filename of html text to include at bottom of each page.  Relative to
+   gitweb.cgi script.  [No default]
+ * GITWEB_HOME_LINK_STR
+   String of the home link on top of all pages, leading to $home_link
+   (usually main gitweb page, which means projects list).  Used as first
+   part of gitweb view "breadcrumb trail": <home> / <project> / <view>.
+   [Default: projects]
+ * GITWEB_SITENAME
+   Name of your site or organization to appear in page titles.  Set it
+   to something descriptive for clearer bookmarks etc.  If not set
+   (if empty) gitweb uses "$SERVER_NAME Git", or "Untitled Git" if
+   SERVER_NAME CGI environment variable is not set (e.g. if running
+   gitweb as standalone script).  [No default]
+ * GITWEB_BASE_URL
+   Git base URLs used for URL to where fetch project from, i.e. full
+   URL is "$git_base_url/$project".  Shown on projects summary page.
+   Repository URL for project can be also configured per repository; this
+   takes precedence over URLs composed from base URL and a project name.
+   Note that you can setup multiple base URLs (for example one for
+   git:// protocol access, another for http:// access) from the gitweb
+   config file.  [No default]
+ * GITWEB_CSS
+   Points to the location where you put gitweb.css on your web server
+   (or to be more generic, the URI of gitweb stylesheet).  Relative to the
+   base URI of gitweb.  Note that you can setup multiple stylesheets from
+   the gitweb config file.  [Default: static/gitweb.css (or
+   static/gitweb.min.css if the CSSMIN variable is defined / CSS minifier
+   is used)]
+ * GITWEB_JS
+   Points to the location where you put gitweb.js on your web server
+   (or to be more generic URI of JavaScript code used by gitweb).
+   Relative to base URI of gitweb.  [Default: static/gitweb.js (or
+   static/gitweb.min.js if JSMIN build variable is defined / JavaScript
+   minifier is used)]
+ * CSSMIN, JSMIN
+   Invocation of a CSS minifier or a JavaScript minifier, respectively,
+   working as a filter (source on standard input, minified result on
+   standard output).  If set, it is used to generate a minified version of
+   'static/gitweb.css' or 'static/gitweb.js', respectively.  *Note* that
+   minified files would have *.min.css and *.min.js extension, which is
+   important if you also set GITWEB_CSS and/or GITWEB_JS.  [No default]
+ * GITWEB_LOGO
+   Points to the location where you put git-logo.png on your web server
+   (or to be more generic URI of logo, 72x27 size, displayed in top right
+   corner of each gitweb page, and used as logo for Atom feed).  Relative
+   to base URI of gitweb.  [Default: static/git-logo.png]
+ * GITWEB_FAVICON
+   Points to the location where you put git-favicon.png on your web server
+   (or to be more generic URI of favicon, assumed to be image/png type;
+   web browsers that support favicons (website icons) may display them
+   in the browser's URL bar and next to site name in bookmarks).  Relative
+   to base URI of gitweb.  [Default: static/git-favicon.png]
+ * GITWEB_CONFIG
+   This Perl file will be loaded using 'do' and can be used to override any
+   of the options above as well as some other options -- see the "Runtime
+   gitweb configuration" section below, and top of 'gitweb.cgi' for their
+   full list and description.  If the environment variable GITWEB_CONFIG
+   is set when gitweb.cgi is executed, then the file specified in the
+   environment variable will be loaded instead of the file specified
+   when gitweb.cgi was created.  [Default: gitweb_config.perl]
+ * GITWEB_CONFIG_SYSTEM
+   This Perl file will be loaded using 'do' as a fallback if GITWEB_CONFIG
+   does not exist.  If the environment variable GITWEB_CONFIG_SYSTEM is set
+   when gitweb.cgi is executed, then the file specified in the environment
+   variable will be loaded instead of the file specified when gitweb.cgi was
+   created.  [Default: /etc/gitweb.conf]
+ * HIGHLIGHT_BIN
+   Path to the highlight executable to use (must be the one from
+   http://www.andre-simon.de due to assumptions about parameters and output).
+   Useful if highlight is not installed on your webserver's PATH.
+   [Default: highlight]

-  to the project repository database (relative to projectroot), followed
-  by the url-encoded project owner on the same line (separated by a space).
-  Spaces in both project path and project owner have to be encoded as either
-  '%20' or '+'.
-
-  Other characters that have to be url-encoded, i.e. replaced by '%'
-  followed by two-digit character number in octal, are: other whitespace
-  characters (because they are field separator in a record), plus sign '+'
-  (because it can be used as replacement for spaces), and percent sign '%'
-  (which is used for encoding / escaping).
-
-  You can generate the projects list index file using the project_index
-  action (the 'TXT' link on projects list page) directly from gitweb.
-
-- By default, even if a project is not visible on projects list page, you
-  can view it nevertheless by hand-crafting a gitweb URL. You can set the
-  GITWEB_STRICT_EXPORT build configuration variable (or the $strict_export
-  variable in the gitweb config file) to only allow viewing of
-  repositories also shown on the overview page.
-
-- Alternatively, you can configure gitweb to only list and allow
-  viewing of the explicitly exported repositories, via the
-  GITWEB_EXPORT_OK build configuration variable (or the $export_ok
-  variable in gitweb config file). If it evaluates to true, gitweb
-  shows repositories only if this file exists in its object database
-  (if directory has the magic file named $export_ok).
-
-- Finally, it is possible to specify an arbitrary perl subroutine that
-  will be called for each project to determine if it can be exported.
-  The subroutine receives an absolute path to the project as its only
-  parameter.
-
-  For example, if you use mod_perl to run the script, and have dumb
-  http protocol authentication configured for your repositories, you
-  can use the following hook to allow access only if the user is
-  authorized to read the files:
-
-    $export_auth_hook = sub {
-        use Apache2::SubRequest ();
-        use Apache2::Const -compile => qw(HTTP_OK);
-        my $path = "$_[0]/HEAD";
-        my $r    = Apache2::RequestUtil->request;
-        my $sub  = $r->lookup_file($path);
-        return $sub->filename eq $path
-            && $sub->status == Apache2::Const::HTTP_OK;
-    };
-
-
-Generating projects list using gitweb
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-We assume that GITWEB_CONFIG has its default Makefile value, namely
-gitweb_config.perl. Put the following in gitweb_make_index.perl file:
-
-	$GITWEB_CONFIG = "gitweb_config.perl";
-	do $GITWEB_CONFIG if -e $GITWEB_CONFIG;
-
-	$projects_list = $projectroot;
-
-Then create the following script to get list of project in the format
-suitable for GITWEB_LIST build configuration variable (or
-$projects_list variable in gitweb config):
-
-	#!/bin/sh
-
-	export GITWEB_CONFIG="gitweb_make_index.perl"
-	export GATEWAY_INTERFACE="CGI/1.1"
-	export HTTP_ACCEPT="*/*"
-	export REQUEST_METHOD="GET"
-	export QUERY_STRING="a=project_index"
-
-	perl -- /var/www/cgi-bin/gitweb.cgi
-
-
-Requirements
-------------
+By default gitweb shows all git repositories under single common repository
+root on a local filesystem; see description of GITWEB_PROJECTROOT build-time
+configuration variable above (and also of GITWEB_LIST).
 
- - Core git tools
- - Perl
- - Perl modules: CGI, Encode, Fcntl, File::Find, File::Basename.
- - web server
+More advanced usage, like limiting access or visibility of repositories and
+managing multiple roots are described on gitweb manpage.

 GIT web Interface
 =================
 
-The one working on:
-  http://git.kernel.org/
-
 From the git version 1.4.0 gitweb is bundled with git.
 
 
-How to configure gitweb for your local system
----------------------------------------------
-
-See also the "Build time configuration" section in the INSTALL
-file for gitweb (in gitweb/INSTALL).
+Build time gitweb configuration
+-------------------------------
+There are many configuration variables which affect building gitweb (among
+others creating gitweb.cgi out of gitweb.perl by replacing placeholders such
+as `++GIT_BINDIR++` by their build-time values).
 
-You can specify the following configuration variables when building GIT:
- * GIT_BINDIR
-   Points where to find the git executable.  You should set it up to
-   the place where the git binary was installed (usually /usr/bin) if you
-   don't install git from sources together with gitweb.  [Default: $(bindir)]
- * GITWEB_SITENAME
-   Shown in the title of all generated pages, defaults to the server name
-   (SERVER_NAME CGI environment variable) if not set. [No default]
- * GITWEB_PROJECTROOT
-   The root directory for all projects shown by gitweb. Must be set
-   correctly for gitweb to find repositories to display.  See also
-   "Gitweb repositories" in the INSTALL file for gitweb.  [Default: /pub/git]
- * GITWEB_PROJECT_MAXDEPTH
-   The filesystem traversing limit for getting the project list; the number
-   is taken as depth relative to the projectroot.  It is used when
-   GITWEB_LIST is a directory (or is not set; then project root is used).
-   Is is meant to speed up project listing on large work trees by limiting
-   search depth.  [Default: 2007]
- * GITWEB_LIST
-   Points to a directory to scan for projects (defaults to project root
-   if not set / if empty) or to a file with explicit listing of projects
-   (together with projects' ownership). See "Generating projects list
-   using gitweb" in INSTALL file for gitweb to find out how to generate
-   such file from scan of a directory. [No default, which means use root
-   directory for projects]
- * GITWEB_EXPORT_OK
-   Show repository only if this file exists (in repository).  Only
-   effective if this variable evaluates to true.  [No default / Not set]
- * GITWEB_STRICT_EXPORT
-   Only allow viewing of repositories also shown on the overview page.
-   This for example makes GITWEB_EXPORT_OK to decide if repository is
-   available and not only if it is shown.  If GITWEB_LIST points to
-   file with list of project, only those repositories listed would be
-   available for gitweb.  [No default]
- * GITWEB_HOMETEXT
-   Points to an .html file which is included on the gitweb project
-   overview page ('projects_list' view), if it exists.  Relative to
-   gitweb.cgi script.  [Default: indextext.html]
- * GITWEB_SITE_HEADER
-   Filename of html text to include at top of each page.  Relative to
-   gitweb.cgi script.  [No default]
- * GITWEB_SITE_FOOTER
-   Filename of html text to include at bottom of each page.  Relative to
-   gitweb.cgi script.  [No default]
- * GITWEB_HOME_LINK_STR
-   String of the home link on top of all pages, leading to $home_link
-   (usually main gitweb page, which means projects list).  Used as first
-   part of gitweb view "breadcrumb trail": <home> / <project> / <view>.
-   [Default: projects]
- * GITWEB_SITENAME
-   Name of your site or organization to appear in page titles.  Set it
-   to something descriptive for clearer bookmarks etc.  If not set
-   (if empty) gitweb uses "$SERVER_NAME Git", or "Untitled Git" if
-   SERVER_NAME CGI environment variable is not set (e.g. if running
-   gitweb as standalone script).  [No default]
- * GITWEB_BASE_URL
-   Git base URLs used for URL to where fetch project from, i.e. full
-   URL is "$git_base_url/$project".  Shown on projects summary page.
-   Repository URL for project can be also configured per repository; this
-   takes precedence over URLs composed from base URL and a project name.
-   Note that you can setup multiple base URLs (for example one for
-   git:// protocol access, another for http:// access) from the gitweb
-   config file.  [No default]
- * GITWEB_CSS
-   Points to the location where you put gitweb.css on your web server
-   (or to be more generic, the URI of gitweb stylesheet).  Relative to the
-   base URI of gitweb.  Note that you can setup multiple stylesheets from
-   the gitweb config file.  [Default: gitweb.css]
- * GITWEB_LOGO
-   Points to the location where you put git-logo.png on your web server
-   (or to be more generic URI of logo, 72x27 size, displayed in top right
-   corner of each gitweb page, and used as logo for Atom feed).  Relative
-   to base URI of gitweb.  [Default: git-logo.png]
- * GITWEB_FAVICON
-   Points to the location where you put git-favicon.png on your web server
-   (or to be more generic URI of favicon, assumed to be image/png type;
-   web browsers that support favicons (website icons) may display them
-   in the browser's URL bar and next to site name in bookmarks).  Relative
-   to base URI of gitweb.  [Default: git-favicon.png]
- * GITWEB_CONFIG
-   This Perl file will be loaded using 'do' and can be used to override any
-   of the options above as well as some other options -- see the "Runtime
-   gitweb configuration" section below, and top of 'gitweb.cgi' for their
-   full list and description.  If the environment variable GITWEB_CONFIG
-   is set when gitweb.cgi is executed, then the file specified in the
-   environment variable will be loaded instead of the file specified
-   when gitweb.cgi was created.  [Default: gitweb_config.perl]
- * GITWEB_CONFIG_SYSTEM
-   This Perl file will be loaded using 'do' as a fallback if GITWEB_CONFIG
-   does not exist.  If the environment variable GITWEB_CONFIG_SYSTEM is set
-   when gitweb.cgi is executed, then the file specified in the environment
-   variable will be loaded instead of the file specified when gitweb.cgi was
-   created.  [Default: /etc/gitweb.conf]
+Building and installing gitweb is described in gitweb's INSTALL file
+(in 'gitweb/INSTALL').
 
 
 Runtime gitweb configuration
 ----------------------------
+Gitweb obtains configuration data from the following sources in the
+following order:
 
-You can adjust gitweb behaviour using the file specified in `GITWEB_CONFIG`
-(defaults to 'gitweb_config.perl' in the same directory as the CGI), and
-as a fallback `GITWEB_CONFIG_SYSTEM` (defaults to /etc/gitweb.conf).
-The most notable thing that is not configurable at compile time are the
-optional features, stored in the '%features' variable.
-
-Ultimate description on how to reconfigure the default features setting
-in your `GITWEB_CONFIG` or per-project in `project.git/config` can be found
-as comments inside 'gitweb.cgi'.
-
-See also the "Gitweb config file" (with an example of config file), and
-the "Gitweb repositories" sections in INSTALL file for gitweb.
-
-
-The gitweb config file is a fragment of perl code. You can set variables
-using "our $variable = value"; text from "#" character until the end
-of a line is ignored. See perlsyn(1) man page for details.
-
-Below is the list of variables which you might want to set in gitweb config.
-See the top of 'gitweb.cgi' for the full list of variables and their
-descriptions.
-
-Gitweb config file variables
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You can set, among others, the following variables in gitweb config files
-(with the exception of $projectroot and $projects_list this list does
-not include variables usually directly set during build):
- * $GIT
-   Core git executable to use.  By default set to "$GIT_BINDIR/git", which
-   in turn is by default set to "$(bindir)/git".  If you use git from binary
-   package, set this to "/usr/bin/git".  This can just be "git" if your
-   webserver has a sensible PATH.  If you have multiple git versions
-   installed it can be used to choose which one to use.
- * $version
-   Gitweb version, set automatically when creating gitweb.cgi from
-   gitweb.perl. You might want to modify it if you are running modified
-   gitweb.
- * $projectroot
-   Absolute filesystem path which will be prepended to project path;
-   the path to repository is $projectroot/$project.  Set to
-   $GITWEB_PROJECTROOT during installation.  This variable have to be
-   set correctly for gitweb to find repositories.
- * $projects_list
-   Source of projects list, either directory to scan, or text file
-   with list of repositories (in the "<URI-encoded repository path> SP
-   <URI-encoded repository owner>" line format; actually there can be
-   any sequence of whitespace in place of space (SP)).  Set to
-   $GITWEB_LIST during installation.  If empty, $projectroot is used
-   to scan for repositories.
- * $my_url, $my_uri
-   Full URL and absolute URL of gitweb script;
-   in earlier versions of gitweb you might have need to set those
-   variables, now there should be no need to do it.
- * $base_url
-   Base URL for relative URLs in pages generated by gitweb,
-   (e.g. $logo, $favicon, @stylesheets if they are relative URLs),
-   needed and used only for URLs with nonempty PATH_INFO via
-   <base href="$base_url>.  Usually gitweb sets its value correctly,
-   and there is no need to set this variable, e.g. to $my_uri or "/".
- * $home_link
-   Target of the home link on top of all pages (the first part of view
-   "breadcrumbs").  By default set to absolute URI of a page ($my_uri).
- * @stylesheets
-   List of URIs of stylesheets (relative to base URI of a page). You
-   might specify more than one stylesheet, for example use gitweb.css
-   as base, with site specific modifications in separate stylesheet
-   to make it easier to upgrade gitweb. You can add 'site' stylesheet
-   for example by using
-      push @stylesheets, "gitweb-site.css";
-   in the gitweb config file.
- * $logo_url, $logo_label
-   URI and label (title) of GIT logo link (or your site logo, if you choose
-   to use different logo image). By default they point to git homepage;
-   in the past they pointed to git documentation at www.kernel.org.
- * $projects_list_description_width
-   The width (in characters) of the projects list "Description" column.
-   Longer descriptions will be cut (trying to cut at word boundary);
-   full description is available as 'title' attribute (usually shown on
-   mouseover).  By default set to 25, which might be too small if you
-   use long project descriptions.
- * @git_base_url_list
-   List of git base URLs used for URL to where fetch project from, shown
-   in project summary page.  Full URL is "$git_base_url/$project".
-   You can setup multiple base URLs (for example one for  git:// protocol
-   access, and one for http:// "dumb" protocol access).  Note that per
-   repository configuration in 'cloneurl' file, or as values of gitweb.url
-   project config.
- * $default_blob_plain_mimetype
-   Default mimetype for blob_plain (raw) view, if mimetype checking
-   doesn't result in some other type; by default 'text/plain'.
- * $default_text_plain_charset
-   Default charset for text files. If not set, web server configuration
-   would be used.
- * $mimetypes_file
-   File to use for (filename extension based) guessing of MIME types before
-   trying /etc/mime.types. Path, if relative, is taken currently as
-   relative to the current git repository.
- * $fallback_encoding
-   Gitweb assumes this charset if line contains non-UTF-8 characters.
-   Fallback decoding is used without error checking, so it can be even
-   'utf-8'. Value must be valid encoding; see Encoding::Supported(3pm) man
-   page for a list.   By default 'latin1', aka. 'iso-8859-1'.
- * @diff_opts
-   Rename detection options for git-diff and git-diff-tree. By default
-   ('-M'); set it to ('-C') or ('-C', '-C') to also detect copies, or
-   set it to () if you don't want to have renames detection.
- * $prevent_xss
-   If true, some gitweb features are disabled to prevent content in
-   repositories from launching cross-site scripting (XSS) attacks.  Set this
-   to true if you don't trust the content of your repositories. The default
-   is false.
-
-
-Projects list file format
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Instead of having gitweb find repositories by scanning filesystem starting
-from $projectroot (or $projects_list, if it points to directory), you can
-provide list of projects by setting $projects_list to a text file with list
-of projects (and some additional info).  This file uses the following
-format:
-
-One record (for project / repository) per line, whitespace separated fields;
-does not support (at least for now) lines continuation (newline escaping).
-Leading and trailing whitespace are ignored, any run of whitespace can be
-used as field separator (rules for Perl's "split(' ', $line)").  Keyed by
-the first field, which is project name, i.e. path to repository GIT_DIR
-relative to $projectroot.  Fields use modified URI encoding, defined in
-RFC 3986, section 2.1 (Percent-Encoding), or rather "Query string encoding"
-(see http://en.wikipedia.org/wiki/Query_string#URL_encoding), the difference
-being that SP (' ') can be encoded as '+' (and therefore '+' has to be also
-percent-encoded).  Reserved characters are: '%' (used for encoding), '+'
-(can be used to encode SPACE), all whitespace characters as defined in Perl,
-including SP, TAB and LF, (used to separate fields in a record).
-
-Currently list of fields is
- * <repository path>  - path to repository GIT_DIR, relative to $projectroot
- * <repository owner> - displayed as repository owner, preferably full name,
-                        or email, or both
-
-You can additionally use $projects_list file to limit which repositories
-are visible, and together with $strict_export to limit access to
-repositories (see "Gitweb repositories" section in gitweb/INSTALL).
-
-
-Per-repository gitweb configuration
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You can also configure individual repositories shown in gitweb by creating
-file in the GIT_DIR of git repository, or by setting some repo configuration
-variable (in GIT_DIR/config).
-
-You can use the following files in repository:
- * README.html
-   A .html file (HTML fragment) which is included on the gitweb project
-   summary page inside <div> block element. You can use it for longer
-   description of a project, to provide links (for example to project's
-   homepage), etc. This is recognized only if XSS prevention is off
-   ($prevent_xss is false); a way to include a readme safely when XSS
-   prevention is on may be worked out in the future.
- * description (or gitweb.description)
-   Short (shortened by default to 25 characters in the projects list page)
-   single line description of a project (of a repository). Plain text file;
-   HTML will be escaped. By default set to
-     Unnamed repository; edit this file to name it for gitweb.
-   from the template during repository creation. You can use the
-   gitweb.description repo configuration variable, but the file takes
-   precedence.
- * cloneurl (or multiple-valued gitweb.url)
-   File with repository URL (used for clone and fetch), one per line.
-   Displayed in the project summary page. You can use multiple-valued
-   gitweb.url repository configuration variable for that, but the file
-   takes precedence.
- * gitweb.owner
-   You can use the gitweb.owner repository configuration variable to set
-   repository's owner. It is displayed in the project list and summary
-   page. If it's not set, filesystem directory's owner is used
-   (via GECOS field / real name field from getpwiud(3)).
- * various gitweb.* config variables (in config)
-   Read description of %feature hash for detailed list, and some
-   descriptions.
-
-
-Webserver configuration
------------------------
-
-If you want to have one URL for both gitweb and your http://
-repositories, you can configure apache like this:
+1. built-in values (some set during build stage),
+2. common system-wide configuration file (`GITWEB_CONFIG_COMMON`,
+   defaults to '/etc/gitweb-common.conf'),
+3. either per-instance configuration file (`GITWEB_CONFIG`, defaults to
+   'gitweb_config.perl' in the same directory as the installed gitweb),
+   or if it does not exists then system-wide configuration file
+   (`GITWEB_CONFIG_SYSTEM`, defaults to '/etc/gitweb.conf').
 
-<VirtualHost *:80>
-    ServerName git.example.org
-    DocumentRoot /pub/git
-    SetEnv	GITWEB_CONFIG	/etc/gitweb.conf
-    RewriteEngine on
-    # make the front page an internal rewrite to the gitweb script
-    RewriteRule ^/$  /cgi-bin/gitweb.cgi
-    # make access for "dumb clients" work
-    RewriteRule ^/(.*\.git/(?!/?(HEAD|info|objects|refs)).*)?$ /cgi-bin/gitweb.cgi%{REQUEST_URI}  [L,PT]
-</VirtualHost>
+Values obtained in later configuration files override values obtained earlier
+in above sequence.
 
-The above configuration expects your public repositories to live under
-/pub/git and will serve them as http://git.domain.org/dir-under-pub-git,
-both as cloneable GIT URL and as browseable gitweb interface.
-If you then start your git-daemon with --base-path=/pub/git --export-all
-then you can even use the git:// URL with exactly the same path.
+You can read defaults in system-wide GITWEB_CONFIG_SYSTEM from GITWEB_CONFIG
+by adding
 
-Setting the environment variable GITWEB_CONFIG will tell gitweb to use
-the named file (i.e. in this example /etc/gitweb.conf) as a
-configuration for gitweb.  Perl variables defined in here will
-override the defaults given at the head of the gitweb.perl (or
-gitweb.cgi).  Look at the comments in that file for information on
-which variables and what they mean.
+  read_config_file($GITWEB_CONFIG_SYSTEM);
 
-If you use the rewrite rules from the example you'll likely also need
-something like the following in your gitweb.conf (or gitweb_config.perl) file:
+at very beginning of per-instance GITWEB_CONFIG file.  In this case
+settings in said per-instance file will override settings from
+system-wide configuration file.  Note that read_config_file checks
+itself that the $GITWEB_CONFIG_SYSTEM file exists.
 
-  @stylesheets = ("/some/absolute/path/gitweb.css");
-  $my_uri = "/";
-  $home_link = "/";
-
-
-PATH_INFO usage
------------------------
-If you enable PATH_INFO usage in gitweb by putting
-
-   $feature{'pathinfo'}{'default'} = [1];
-
-in your gitweb.conf, it is possible to set up your server so that it
-consumes and produces URLs in the form
-
-http://git.example.com/project.git/shortlog/sometag
-
-by using a configuration such as the following, that assumes that
-/var/www/gitweb is the DocumentRoot of your webserver, and that it
-contains the gitweb.cgi script and complementary static files
-(stylesheet, favicon):
-
-<VirtualHost *:80>
-	ServerAlias git.example.com
-
-	DocumentRoot /var/www/gitweb
-
-	<Directory /var/www/gitweb>
-		Options ExecCGI
-		AddHandler cgi-script cgi
-
-		DirectoryIndex gitweb.cgi
-
-		RewriteEngine On
-		RewriteCond %{REQUEST_FILENAME} !-f
-		RewriteCond %{REQUEST_FILENAME} !-d
-		RewriteRule ^.* /gitweb.cgi/$0 [L,PT]
-	</Directory>
-</VirtualHost>
-
-The rewrite rule guarantees that existing static files will be properly
-served, whereas any other URL will be passed to gitweb as PATH_INFO
-parameter.
-
-Notice that in this case you don't need special settings for
-@stylesheets, $my_uri and $home_link, but you lose "dumb client" access
-to your project .git dirs. A possible workaround for the latter is the
-following: in your project root dir (e.g. /pub/git) have the projects
-named without a .git extension (e.g. /pub/git/project instead of
-/pub/git/project.git) and configure Apache as follows:
-
-<VirtualHost *:80>
-	ServerAlias git.example.com
-
-	DocumentRoot /var/www/gitweb
-
-	AliasMatch ^(/.*?)(\.git)(/.*)?$ /pub/git$1$3
-	<Directory /var/www/gitweb>
-		Options ExecCGI
-		AddHandler cgi-script cgi
-
-		DirectoryIndex gitweb.cgi
-
-		RewriteEngine On
-		RewriteCond %{REQUEST_FILENAME} !-f
-		RewriteCond %{REQUEST_FILENAME} !-d
-		RewriteRule ^.* /gitweb.cgi/$0 [L,PT]
-	</Directory>
-</VirtualHost>
-
-The additional AliasMatch makes it so that
-
-http://git.example.com/project.git
-
-will give raw access to the project's git dir (so that the project can
-be cloned), while
-
-http://git.example.com/project
+The most notable thing that is not configurable at compile time are the
+optional features, stored in the '%features' variable.
 
-will provide human-friendly gitweb access.
+Ultimate description on how to reconfigure the default features setting
+in your `GITWEB_CONFIG` or per-project in `project.git/config` can be found
+as comments inside 'gitweb.cgi'.
 
-This solution is not 100% bulletproof, in the sense that if some project
-has a named ref (branch, tag) starting with 'git/', then paths such as
+See also gitweb.conf(5) manpage.
 
-http://git.example.com/project/command/abranch..git/abranch
 
-will fail with a 404 error.
+Web server configuration
+------------------------
+Gitweb can be run as CGI script, as legacy mod_perl application (using
+ModPerl::Registry), and as FastCGI script.  You can find some simple examples
+in "Example web server configuration" section in INSTALL file for gitweb (in
+gitweb/INSTALL).
 
+See "Webserver configuration" and "Advanced web server setup" sections in
+gitweb(1) manpage.

+GIT web interface (gitweb) - JavaScript
+=======================================
+
+This directory holds JavaScript code used by gitweb (GIT web interface).
+Scripts from there would be concatenated together in the order specified
+by gitweb/Makefile into gitweb/static/gitweb.js, during building of
+gitweb/gitweb.cgi (during gitweb building).  The resulting file (or its
+minification) would then be installed / deployed together with gitweb.
+
+Scripts in 'lib/' subdirectory compose generic JavaScript library,
+providing features required by gitweb but in no way limited to gitweb
+only.  In the future those scripts could be replaced by some JavaScript
+library / framework, like e.g. jQuery, YUI, Prototype, MooTools, Dojo,
+ExtJS, Script.aculo.us or SproutCore.
+
+All scripts that manipulate gitweb output should be put outside 'lib/',
+directly in this directory ('gitweb/static/js/').  Those scripts would
+have to be rewritten if gitweb moves to using some JavaScript library.
+
+See also comments in gitweb/Makefile.

+/*
+ * File write-locks as used by Git.
+ *
+ * For an overview of how to use the lockfile API, please see
+ *
+ *     Documentation/technical/api-lockfile.txt
+ *
+ * This module keeps track of all locked files in lock_file_list for
+ * use at cleanup. This list and the lock_file objects that comprise
+ * it must be kept in self-consistent states at all time, because the
+ * program can be interrupted any time by a signal, in which case the
+ * signal handler will walk through the list attempting to clean up
+ * any open lock files.
+ *
+ * A lockfile is owned by the process that created it. The lock_file
+ * object has an "owner" field that records its owner. This field is
+ * used to prevent a forked process from closing a lockfile created by
+ * its parent.
+ *
+ * The possible states of a lock_file object are as follows:
+ *
+ * - Uninitialized.  In this state the object's on_list field must be
+ *   zero but the rest of its contents need not be initialized.  As
+ *   soon as the object is used in any way, it is irrevocably
+ *   registered in the lock_file_list, and on_list is set.
+ *
+ * - Locked, lockfile open (after hold_lock_file_for_update(),
+ *   hold_lock_file_for_append(), or reopen_lock_file()). In this
+ *   state:
+ *   - the lockfile exists
+ *   - active is set
+ *   - filename holds the filename of the lockfile
+ *   - fd holds a file descriptor open for writing to the lockfile
+ *   - fp holds a pointer to an open FILE object if and only if
+ *     fdopen_lock_file() has been called on the object
+ *   - owner holds the PID of the process that locked the file
+ *
+ * - Locked, lockfile closed (after successful close_lock_file()).
+ *   Same as the previous state, except that the lockfile is closed
+ *   and fd is -1.
+ *
+ * - Unlocked (after commit_lock_file(), commit_lock_file_to(),
+ *   rollback_lock_file(), a failed attempt to lock, or a failed
+ *   close_lock_file()).  In this state:
+ *   - active is unset
+ *   - filename is empty (usually, though there are transitory
+ *     states in which this condition doesn't hold). Client code should
+ *     *not* rely on the filename being empty in this state.
+ *   - fd is -1
+ *   - the object is left registered in the lock_file_list, and
+ *     on_list is set.

+ * up to the caller to decide how to combine the two notes. The decision is
+ * made by passing in a function of the following form. The function accepts
+ * two SHA1s -- of the existing note and the new note, respectively. The
+ * function then combines the notes in whatever way it sees fit, and writes the
+ * resulting SHA1 into the first SHA1 argument (cur_sha1). A non-zero return
+ * value indicates failure.
+ *
+ * The two given SHA1s shall both be non-NULL and different from each other.
+ * Either of them (but not both) may be == null_sha1, which indicates an
+ * empty/non-existent note. If the resulting SHA1 (cur_sha1) is == null_sha1,
+ * the note will be removed from the notes tree.

+=item credential( CREDENTIAL_HASHREF, CODE )
+
+Executes C<git credential> for a given set of credentials and specified
+operation.  In both forms C<CREDENTIAL_HASHREF> needs to be a reference to
+a hash which stores credentials.  Under certain conditions the hash can
+change.
+
+In the first form, C<OPERATION> can be C<'fill'>, C<'approve'> or C<'reject'>,
+and function will execute corresponding C<git credential> sub-command.  If
+it's omitted C<'fill'> is assumed.  In case of C<'fill'> the values stored in
+C<CREDENTIAL_HASHREF> will be changed to the ones returned by the C<git
+credential fill> command.  The usual usage would look something like:
+
+	my %cred = (
+		'protocol' => 'https',
+		'host' => 'example.com',
+		'username' => 'bob'
+	);
+	Git::credential \%cred;

+		Git::credential \%cred, 'approve';
+		... do more stuff ...
+	} else {
+		Git::credential \%cred, 'reject';
+	}
+
+In the second form, C<CODE> needs to be a reference to a subroutine.  The
+function will execute C<git credential fill> to fill the provided credential
+hash, then call C<CODE> with C<CREDENTIAL_HASHREF> as the sole argument.  If
+C<CODE>'s return value is defined, the function will execute C<git credential
+approve> (if return value yields true) or C<git credential reject> (if return
+value is false).  If the return value is undef, nothing at all is executed;
+this is useful, for example, if the credential could neither be verified nor
+rejected due to an unrelated network error.  The return value is the same as
+what C<CODE> returns.  With this form, the usage might look as follows:
+
+	if (Git::credential {
+		'protocol' => 'https',
+		'host' => 'example.com',
+		'username' => 'bob'
+	}, sub {

+
+Git's internal Perl interface to gettext via L<Locale::Messages>. If
+L<Locale::Messages> can't be loaded (it's not a core module) we
+provide stub passthrough fallbacks.
+
+This is a distilled interface to gettext, see C<info '(gettext)Perl'>
+for the full interface. This module implements only a small part of
+it.
+
+=head1 FUNCTIONS
+
+=head2 __($)
+
+L<Locale::Messages>'s gettext function if all goes well, otherwise our
+passthrough fallback function.

+# Tie::File seems to be prone to offset errors if revisions get sparse,

+# one of my favorite modules is out :<  Next up would be one of the DBM
+# modules, but I'm not sure which is most portable...
+#
+# This is the replacement for the rev_db format, which was too big
+# and inefficient for large repositories with a lot of sparse history
+# (mainly tags)
+#
+# The format is this:
+#   - 24 bytes for every record,
+#     * 4 bytes for the integer representing an SVN revision number
+#     * 20 bytes representing the sha1 of a git commit
+#   - No empty padding records like the old format
+#     (except the last record, which can be overwritten)
+#   - new records are written append-only since SVN revision numbers
+#     increase monotonically
+#   - lookups on SVN revision number are done via a binary search
+#   - Piping the file to xxd -c24 is a good way of dumping it for
+#     viewing or editing (piped back through xxd -r), should the need
+#     ever arise.
+#   - The last record can be padding revision with an all-zero sha1
+#     This is used to optimize fetch performance when using multiple
+#     "fetch" directives in .git/config
+#
+# These files are disposable unless noMetadata or useSvmProps is set

+=head1 DESCRIPTION
+
+This module is an implementation detail of the "git svn" command.
+Do not use it unless you are developing git-svn.
+
+This module adapts the C<SVN::Delta::Editor> object returned by
+C<SVN::Delta::get_commit_editor> and drives it to convey the
+difference between two git tree objects to a remote Subversion
+repository.
+
+The interface will change as git-svn evolves.
+
+=head1 DEPENDENCIES
+
+Subversion perl bindings,
+the core L<Carp> and L<IO::File> modules,
+and git's L<Git> helper module.
+
+C<Git::SVN::Editor> has not been tested using callers other than
+B<git-svn> itself.
+
+=head1 SEE ALSO
+
+L<SVN::Delta>,
+L<Git::SVN::Fetcher>.
+
+=head1 INCOMPATIBILITIES
+
+None reported.
+
+=head1 BUGS
+
+None.

+=head1 DESCRIPTION
+
+This is a subclass of C<SVN::Delta::Editor>, which means it implements
+callbacks to act as a consumer of Subversion tree deltas.  This
+particular implementation of those callbacks is meant to store
+information about the resulting content which B<git svn fetch> could
+use to populate new commits and new entries for F<unhandled.log>.
+More specifically:
+
+=over
+
+=item * Additions, removals, and modifications of files are propagated
+to git-svn's index file F<$GIT_DIR/svn/$refname/index> using
+B<git update-index>.
+
+=item * Changes in Subversion path properties are recorded in the
+C<dir_prop> and C<file_prop> fields (which are hashes).
+
+=item * Addition and removal of empty directories are indicated by
+entries with value 1 and 0 respectively in the C<empty> hash.
+
+=item * Paths that are present but cannot be conveyed (presumably due
+to permissions) are recorded in the C<absent_file> and
+C<absent_dirs> hashes.  For each key, the corresponding value is
+a list of paths under that directory that were present but
+could not be conveyed.
+
+=back
+
+The interface is unstable.  Do not use this module unless you are
+developing git-svn.
+
+=head1 DEPENDENCIES
+
+L<SVN::Delta> from the Subversion perl bindings,
+the core L<Carp>, L<File::Basename>, and L<IO::File> modules,
+and git's L<Git> helper module.
+
+C<Git::SVN::Fetcher> has not been tested using callers other than
+B<git-svn> itself.

+=head1 NAME
+
+Git::SVN::Memoize::YAML - store Memoized data in YAML format
+
+=head1 SYNOPSIS
+
+    use Memoize;
+    use Git::SVN::Memoize::YAML;
+
+    tie my %cache => 'Git::SVN::Memoize::YAML', $filename;
+    memoize('slow_function', SCALAR_CACHE => [HASH => \%cache]);
+    slow_function(arguments);
+
+=head1 DESCRIPTION
+
+This module provides a class that can be used to tie a hash to a
+YAML file.  The file is read when the hash is initialized and
+rewritten when the hash is destroyed.
+
+The intent is to allow L<Memoize> to back its cache with a file in
+YAML format, just like L<Memoize::Storable> allows L<Memoize> to
+back its cache with a file in Storable format.  Unlike the Storable
+format, the YAML format is platform-independent and fairly stable.
+
+Carps on error.
+
+=head1 DIAGNOSTICS
+
+See L<YAML::Any>.
+
+=head1 DEPENDENCIES
+
+L<YAML::Any> from CPAN.
+
+=head1 INCOMPATIBILITIES
+
+None reported.
+
+=head1 BUGS
+
+The entire cache is read into a Perl hash when loading the file,
+so this is not very scalable.

+Git::SVN::Ra - Subversion remote access functions for git-svn
+
+=head1 SYNOPSIS
+
+    use Git::SVN::Ra;
+
+    my $ra = Git::SVN::Ra->new($branchurl);
+    my ($dirents, $fetched_revnum, $props) =
+        $ra->get_dir('.', $SVN::Core::INVALID_REVNUM);
+
+=head1 DESCRIPTION
+
+This is a wrapper around the L<SVN::Ra> module for use by B<git-svn>.
+It fills in some default parameters (such as the authentication
+scheme), smooths over incompatibilities between libsvn versions, adds
+caching, and implements some functions specific to B<git-svn>.
+
+Do not use it unless you are developing git-svn.  The interface will
+change as git-svn evolves.
+
+=head1 DEPENDENCIES
+
+Subversion perl bindings,
+L<Git::SVN>.
+
+C<Git::SVN::Ra> has not been tested using callers other than
+B<git-svn> itself.
+
+=head1 SEE ALSO
+
+L<SVN::Ra>.
+
+=head1 INCOMPATIBILITIES
+
+None reported.
+
+=head1 BUGS
+
+None.

+Core GIT Translations
+=====================
+
+This directory holds the translations for the core of Git. This document
+describes how you can contribute to the effort of enhancing the language
+coverage and maintaining the translation.
+
+The localization (l10n) coordinator, Jiang Xin <worldhello.net@gmail.com>,
+coordinates our localization effort in the l10 coordinator repository:
+
+        https://github.com/git-l10n/git-po/
+
+As a contributor for a language XX, you should first check TEAMS file in
+this directory to see whether a dedicated repository for your language XX
+exists. Fork the dedicated repository and start to work if it exists.
+
+If you are the first contributor for the language XX, please fork this
+repository, prepare and/or update the translated message file po/XX.po
+(described later), and ask the l10n coordinator to pull your work.
+
+If there are multiple contributors for the same language, please first
+coordinate among yourselves and nominate the team leader for your
+language, so that the l10n coordinator only needs to interact with one
+person per language.
+
+The overall data-flow looks like this:
+
+    +-------------------+            +------------------+

+ * L10n coordinator asks the result to be pulled (4).
+
+
+Maintaining the po/git.pot file
+-------------------------------
+
+(This is done by the l10n coordinator).
+
+The po/git.pot file contains a message catalog extracted from Git's
+sources. The l10n coordinator maintains it by adding new translations with
+msginit(1), or update existing ones with msgmerge(1).  In order to update
+the Git sources to extract the messages from, the l10n coordinator is
+expected to pull from the main git repository at strategic point in
+history (e.g. when a major release and release candidates are tagged),
+and then run "make pot" at the top-level directory.
+
+Language contributors use this file to prepare translations for their
+language, but they are not expected to modify it.
+
+
+Initializing a XX.po file
+-------------------------
+
+(This is done by the language teams).
+
+If your language XX does not have translated message file po/XX.po yet,
+you add a translation for the first time by running:
+
+    msginit --locale=XX
+
+in the po/ directory, where XX is the locale, e.g. "de", "is", "pt_BR",
+"zh_CN", etc.
+
+Then edit the automatically generated copyright info in your new XX.po
+to be correct, e.g. for Icelandic:
+
+    @@ -1,6 +1,6 @@
+    -# Icelandic translations for PACKAGE package.
+    -# Copyright (C) 2010 THE PACKAGE'S COPYRIGHT HOLDER
+    -# This file is distributed under the same license as the PACKAGE package.
+    +# Icelandic translations for Git.
+    +# Copyright (C) 2010 Ævar Arnfjörð Bjarmason <avarab@gmail.com>
+    +# This file is distributed under the same license as the Git package.
+     # Ævar Arnfjörð Bjarmason <avarab@gmail.com>, 2010.
+
+And change references to PACKAGE VERSION in the PO Header Entry to
+just "Git":
+
+    perl -pi -e 's/(?<="Project-Id-Version: )PACKAGE VERSION/Git/' XX.po
+
+Once you are done testing the translation (see below), commit the result
+and ask the l10n coordinator to pull from you.
+
+
+Updating a XX.po file
+---------------------
+
+(This is done by the language teams).
+
+If you are replacing translation strings in an existing XX.po file to
+improve the translation, just edit the file.
+
+If there's an existing XX.po file for your language, but the repository
+of the l10n coordinator has newer po/git.pot file, you would need to first
+pull from the l10n coordinator (see the beginning of this document for its
+URL), and then update the existing translation by running:
+
+    msgmerge --add-location --backup=off -U XX.po git.pot
+
+in the po/ directory, where XX.po is the file you want to update.
+
+Once you are done testing the translation (see below), commit the result
+and ask the l10n coordinator to pull from you.
+
+
+Testing your changes
+--------------------
+
+(This is done by the language teams, after creating or updating XX.po file).
+
+Before you submit your changes go back to the top-level and do:
+
+    make
+
+On systems with GNU gettext (i.e. not Solaris) this will compile your
+changed PO file with `msgfmt --check`, the --check option flags many
+common errors, e.g. missing printf format strings, or translated
+messages that deviate from the originals in whether they begin/end
+with a newline or not.
+
+
+Marking strings for translation
+-------------------------------
+
+(This is done by the core developers).
+
+Before strings can be translated they first have to be marked for
+translation.
+
+Git uses an internationalization interface that wraps the system's
+gettext library, so most of the advice in your gettext documentation
+(on GNU systems `info gettext` in a terminal) applies.
+
+General advice:
+
+ - Don't mark everything for translation, only strings which will be
+   read by humans (the porcelain interface) should be translated.
+
+   The output from Git's plumbing utilities will primarily be read by
+   programs and would break scripts under non-C locales if it was
+   translated. Plumbing strings should not be translated, since
+   they're part of Git's API.
+
+ - Adjust the strings so that they're easy to translate. Most of the
+   advice in `info '(gettext)Preparing Strings'` applies here.
+
+ - If something is unclear or ambiguous you can use a "TRANSLATORS"
+   comment to tell the translators what to make of it. These will be
+   extracted by xgettext(1) and put in the po/*.po files, e.g. from
+   git-am.sh:
+
+       # TRANSLATORS: Make sure to include [y], [n], [e], [v] and [a]
+       # in your translation. The program will only accept English
+       # input at this point.
+       gettext "Apply? [y]es/[n]o/[e]dit/[v]iew patch/[a]ccept all "
+
+   Or in C, from builtin/revert.c:
+
+       /* TRANSLATORS: %s will be "revert" or "cherry-pick" */
+       die(_("%s: Unable to write new index file"), action_name(opts));
+
+We provide wrappers for C, Shell and Perl programs. Here's how they're
+used:
+
+C:
+
+ - Include builtin.h at the top, it'll pull in gettext.h, which
+   defines the gettext interface. Consult with the list if you need to
+   use gettext.h directly.
+
+ - The C interface is a subset of the normal GNU gettext
+   interface. We currently export these functions:
+
+   - _()
+
+    Mark and translate a string. E.g.:
+
+        printf(_("HEAD is now at %s"), hex);
+
+   - Q_()
+
+    Mark and translate a plural string. E.g.:
+
+        printf(Q_("%d commit", "%d commits", number_of_commits));
+
+    This is just a wrapper for the ngettext() function.
+
+   - N_()
+
+    A no-op pass-through macro for marking strings inside static
+    initializations, e.g.:
+
+        static const char *reset_type_names[] = {
+            N_("mixed"), N_("soft"), N_("hard"), N_("merge"), N_("keep"), NULL
+        };
+
+    And then, later:
+
+        die(_("%s reset is not allowed in a bare repository"),
+               _(reset_type_names[reset_type]));
+
+    Here _() couldn't have statically determined what the translation
+    string will be, but since it was already marked for translation
+    with N_() the look-up in the message catalog will succeed.
+
+Shell:
+
+ - The Git gettext shell interface is just a wrapper for
+   gettext.sh. Import it right after git-sh-setup like this:
+
+       . git-sh-setup
+       . git-sh-i18n
+
+   And then use the gettext or eval_gettext functions:
+
+       # For constant interface messages:
+       gettext "A message for the user"; echo
+
+       # To interpolate variables:
+       details="oh noes"
+       eval_gettext "An error occurred: \$details"; echo
+
+   In addition we have wrappers for messages that end with a trailing
+   newline. I.e. you could write the above as:
+
+       # For constant interface messages:
+       gettextln "A message for the user"
+
+       # To interpolate variables:
+       details="oh noes"
+       eval_gettextln "An error occurred: \$details"
+
+   More documentation about the interface is available in the GNU info
+   page: `info '(gettext)sh'`. Looking at git-am.sh (the first shell
+   command to be translated) for examples is also useful:
+
+       git log --reverse -p --grep=i18n git-am.sh
+
+Perl:
+
+ - The Git::I18N module provides a limited subset of the
+   Locale::Messages functionality, e.g.:
+
+       use Git::I18N;
+       print __("Welcome to Git!\n");
+       printf __("The following error occurred: %s\n"), $error;
+
+   Run `perldoc perl/Git/I18N.pm` for more info.
+
+
+Testing marked strings
+----------------------
+
+Even if you've correctly marked porcelain strings for translation
+something in the test suite might still depend on the US English
+version of the strings, e.g. to grep some error message or other
+output.
+
+To smoke out issues like these Git can be compiled with gettext poison
+support, at the top-level:
+
+    make GETTEXT_POISON=YesPlease
+
+That'll give you a git which emits gibberish on every call to
+gettext. It's obviously not meant to be installed, but you should run
+the test suite with it:
+
+    cd t && prove -j 9 ./t[0-9]*.sh
+
+If tests break with it you should inspect them manually and see if
+what you're translating is sane, i.e. that you're not translating
+plumbing output.
+
+If not you should replace calls to grep with test_i18ngrep, or
+test_cmp calls with test_i18ncmp. If that's not enough you can skip
+the whole test by making it depend on the C_LOCALE_OUTPUT
+prerequisite. See existing test files with this prerequisite for
+examples.

+ * A ref_entry represents either a reference or a "subdirectory" of
+ * references.
+ *
+ * Each directory in the reference namespace is represented by a
+ * ref_entry with (flags & REF_DIR) set and containing a subdir member
+ * that holds the entries in that directory that have been read so
+ * far.  If (flags & REF_INCOMPLETE) is set, then the directory and
+ * its subdirectories haven't been read yet.  REF_INCOMPLETE is only
+ * used for loose reference directories.
+ *
+ * References are represented by a ref_entry with (flags & REF_DIR)
+ * unset and a value member that describes the reference's value.  The
+ * flag member is at the ref_entry level, but it is also needed to
+ * interpret the contents of the value field (in other words, a
+ * ref_value object is not very much use without the enclosing
+ * ref_entry).
+ *
+ * Reference names cannot end with slash and directories' names are
+ * always stored with a trailing slash (except for the top-level
+ * directory, which is always denoted by "").  This has two nice
+ * consequences: (1) when the entries in each subdir are sorted
+ * lexicographically by name (as they usually are), the references in
+ * a whole tree can be generated in lexicographic order by traversing
+ * the tree in left-to-right, depth-first order; (2) the names of
+ * references and subdirectories cannot conflict, and therefore the
+ * presence of an empty subdirectory does not block the creation of a
+ * similarly-named reference.  (The fact that reference names with the
+ * same leading components can conflict *with each other* is a
+ * separate issue that is regulated by is_refname_available().)
+ *
+ * Please note that the name field contains the fully-qualified
+ * reference (or subdirectory) name.  Space could be saved by only
+ * storing the relative names.  But that would require the full names
+ * to be generated on the fly when iterating in do_for_each_ref(), and
+ * would break callback functions, who have always been able to assume
+ * that the name strings that they are passed will not be freed during
+ * the iteration.

+ * A "relevant" commit is one that is !UNINTERESTING (ie we are including it

+ * a limited list, during processing we can generally ignore boundary merges
+ * coming from outside the graph, (ie from irrelevant parents), and treat

+ *
+ * Treating bottom commits as relevant ensures that a limited graph's
+ * connection to the actual bottom commit is not viewed as a side branch, but
+ * treated as part of the graph. For example:
+ *
+ *   ....Z...A---X---o---o---B
+ *        .     /
+ *         W---Y

+ * When computing "A..B", the A-X connection is at least as important as

 #ifndef STRBUF_H
 #define STRBUF_H
 
-/*
- * Strbuf's can be use in many ways: as a byte array, or to store arbitrary
- * long, overflow safe strings.
- *
- * Strbufs has some invariants that are very important to keep in mind:
- *
- * 1. the ->buf member is always malloc-ed, hence strbuf's can be used to
- *    build complex strings/buffers whose final size isn't easily known.
- *
- *    It is NOT legal to copy the ->buf pointer away.
- *    `strbuf_detach' is the operation that detaches a buffer from its shell
- *    while keeping the shell valid wrt its invariants.
- *
- * 2. the ->buf member is a byte array that has at least ->len + 1 bytes
- *    allocated. The extra byte is used to store a '\0', allowing the ->buf
- *    member to be a valid C-string. Every strbuf function ensure this
- *    invariant is preserved.
- *
- *    Note that it is OK to "play" with the buffer directly if you work it
- *    that way:
- *
- *    strbuf_grow(sb, SOME_SIZE);
- *       ... Here, the memory array starting at sb->buf, and of length
- *       ... strbuf_avail(sb) is all yours, and you are sure that
- *       ... strbuf_avail(sb) is at least SOME_SIZE.
- *    strbuf_setlen(sb, sb->len + SOME_OTHER_SIZE);
- *
- *    Of course, SOME_OTHER_SIZE must be smaller or equal to strbuf_avail(sb).
- *
- *    Doing so is safe, though if it has to be done in many places, adding the
- *    missing API to the strbuf module is the way to go.
- *
- *    XXX: do _not_ assume that the area that is yours is of size ->alloc - 1
- *         even if it's true in the current implementation. Alloc is somehow a
- *         "private" member that should not be messed with.

+prove and other harnesses come with a lot of useful options. The
+--state option in particular is very useful:
+
+    # Repeat until no more failures
+    $ prove -j 15 --state=failed,save ./t[0-9]*.sh
+
+You can give DEFAULT_TEST_TARGET=prove on the make command (or define it
+in config.mak) to cause "make test" to run tests under prove.
+GIT_PROVE_OPTS can be used to pass additional options, e.g.
+
+    $ make DEFAULT_TEST_TARGET=prove GIT_PROVE_OPTS='--timer --jobs 16' test
+
+You can also run each test individually from command line, like this:
+
+    $ sh ./t3010-ls-files-killed-modified.sh
+    ok 1 - git update-index --add to add various paths.
+    ok 2 - git ls-files -k to show killed files.
+    ok 3 - validate git ls-files -k output.
+    ok 4 - git ls-files -m to show modified files.
+    ok 5 - validate git ls-files -m output.
+    # passed all 5 test(s)
+    1..5
 
 You can pass --verbose (or -v), --debug (or -d), and --immediate
 (or -i) command line argument to the test, or by setting GIT_TEST_OPTS
 appropriately before running "make".
 
+-v::
 --verbose::
 	This makes the test more verbose.  Specifically, the
 	command being run and their output if any are also
 	output.
 
+--verbose-only=<pattern>::
+	Like --verbose, but the effect is limited to tests with
+	numbers matching <pattern>.  The number matched against is
+	simply the running count of the test within the file.
+
+-x::
+	Turn on shell tracing (i.e., `set -x`) during the tests
+	themselves. Implies `--verbose`. Note that this can cause
+	failures in some tests which redirect and test the
+	output of shell functions. Use with caution.
+
+-d::
 --debug::
 	This may help the person who is developing a new test.
 	It causes the command defined with test_debug to run.
+	The "trash" directory (used to store all temporary data
+	during testing) is not deleted even if there are no
+	failed tests so that you can inspect its contents after
+	the test finished.
 
+-i::
 --immediate::
 	This causes the test to immediately exit upon the first
-	failed test.
+	failed test. Cleanup commands requested with
+	test_when_finished are not executed if the test failed,
+	in order to keep the state for inspection by the tester
+	to diagnose the bug.
 
+-l::
 --long-tests::
 	This causes additional long-running tests to be run (where
 	available), for more exhaustive testing.
 
---valgrind::
-	Execute all Git binaries with valgrind and exit with status
-	126 on errors (just like regular tests, this will only stop
-	the test script when running under -i).  Valgrind errors
-	go to stderr, so you might want to pass the -v option, too.
+-r::
+--run=<test-selector>::
+	Run only the subset of tests indicated by
+	<test-selector>.  See section "Skipping Tests" below for
+	<test-selector> syntax.
+
+--valgrind=<tool>::
+	Execute all Git binaries under valgrind tool <tool> and exit
+	with status 126 on errors (just like regular tests, this will
+	only stop the test script when running under -i).
 
 	Since it makes no sense to run the tests with --valgrind and
 	not see any output, this option implies --verbose.  For
 	convenience, it also implies --tee.
 
+	<tool> defaults to 'memcheck', just like valgrind itself.
+	Other particularly useful choices include 'helgrind' and
+	'drd', but you may use any tool recognized by your valgrind
+	installation.
+
+	As a special case, <tool> can be 'memcheck-fast', which uses
+	memcheck but disables --track-origins.  Use this if you are
+	running tests in bulk, to see if there are _any_ memory
+	issues.
+
+	Note that memcheck is run with the option --leak-check=no,
+	as the git process is short-lived and some errors are not
+	interesting. In order to run a single command under the same
+	conditions manually, you should set GIT_VALGRIND to point to
+	the 't/valgrind/' directory and use the commands under
+	't/valgrind/bin/'.
+
+--valgrind-only=<pattern>::
+	Like --valgrind, but the effect is limited to tests with
+	numbers matching <pattern>.  The number matched against is
+	simply the running count of the test within the file.
+
 --tee::
 	In addition to printing the test output to the terminal,
 	write it to files named 't/test-results/$TEST_NAME.out'.
 	As the names depend on the tests' file names, it is safe to
 	run the tests with this option in parallel.
 
+--with-dashes::
+	By default tests are run without dashed forms of
+	commands (like git-commit) in the PATH (it only uses
+	wrappers from ../bin-wrappers).  Use this option to include
+	the build directory (..) in the PATH, which contains all
+	the dashed forms of commands.  This option is currently
+	implied by other options like --valgrind and
+	GIT_TEST_INSTALLED.
+
+--root=<directory>::
+	Create "trash" directories used to store all temporary data during
+	testing under <directory>, instead of the t/ directory.
+	Using this option with a RAM-based filesystem (such as tmpfs)
+	can massively speed up the test suite.
+
+You can also set the GIT_TEST_INSTALLED environment variable to
+the bindir of an existing git installation to test that installation.
+You still need to have built this git sandbox, from which various
+test-* support programs, templates, and perl libraries are used.
+If your installed git is incomplete, it will silently test parts of
+your built version instead.
+
+When using GIT_TEST_INSTALLED, you can also set GIT_TEST_EXEC_PATH to
+override the location of the dashed-form subcommands (what
+GIT_EXEC_PATH would be used for during normal operation).
+GIT_TEST_EXEC_PATH defaults to `$GIT_TEST_INSTALLED/git --exec-path`.

 Skipping Tests
 --------------
 
@@ -97,10 +203,77 @@ and either can match the "t[0-9]{4}" part to skip the whole
 test, or t[0-9]{4} followed by ".$number" to say which
 particular test to skip.
 
-Note that some tests in the existing test suite rely on previous
-test item, so you cannot arbitrarily disable one and expect the
-remainder of test to check what the test originally was intended
-to check.
+For an individual test suite --run could be used to specify that
+only some tests should be run or that some tests should be
+excluded from a run.
+
+The argument for --run is a list of individual test numbers or
+ranges with an optional negation prefix that define what tests in
+a test suite to include in the run.  A range is two numbers
+separated with a dash and matches a range of tests with both ends
+been included.  You may omit the first or the second number to
+mean "from the first test" or "up to the very last test"
+respectively.
+
+Optional prefix of '!' means that the test or a range of tests
+should be excluded from the run.
+
+If --run starts with an unprefixed number or range the initial
+set of tests to run is empty. If the first item starts with '!'
+all the tests are added to the initial set.  After initial set is
+determined every test number or range is added or excluded from
+the set one by one, from left to right.
+
+Individual numbers or ranges could be separated either by a space
+or a comma.
+
+For example, to run only tests up to a specific test (21), one
+could do this:
+
+    $ sh ./t9200-git-cvsexport-commit.sh --run='1-21'
+
+or this:
+
+    $ sh ./t9200-git-cvsexport-commit.sh --run='-21'
+
+Common case is to run several setup tests (1, 2, 3) and then a
+specific test (21) that relies on that setup:
+
+    $ sh ./t9200-git-cvsexport-commit.sh --run='1 2 3 21'
+
+or:
+
+    $ sh ./t9200-git-cvsexport-commit.sh --run=1,2,3,21
+
+or:
+
+    $ sh ./t9200-git-cvsexport-commit.sh --run='-3 21'
+
+As noted above, the test set is built going though items left to
+right, so this:
+
+    $ sh ./t9200-git-cvsexport-commit.sh --run='1-4 !3'
+
+will run tests 1, 2, and 4.  Items that comes later have higher
+precendence.  It means that this:
+
+    $ sh ./t9200-git-cvsexport-commit.sh --run='!3 1-4'
+
+would just run tests from 1 to 4, including 3.
+
+You may use negation with ranges.  The following will run all
+test in the test suite except from 7 up to 11:
+
+    $ sh ./t9200-git-cvsexport-commit.sh --run='!7-11'
+
+Some tests in a test suite rely on the previous tests performing
+certain actions, specifically some tests are designated as
+"setup" test, so you cannot _arbitrarily_ disable one test and
+expect the rest to function correctly.
+
+--run is mostly useful when you want to focus on a specific test
+and know what setup is needed for it.  Or when you want to run
+everything up to a certain test.

    consistently when command line arguments --verbose (or -v),
    --debug (or -d), and --immediate (or -i) is given.
 
+Do's, don'ts & things to keep in mind
+-------------------------------------
+
+Here are a few examples of things you probably should and shouldn't do
+when writing tests.
+
+Do:
+
+ - Put all code inside test_expect_success and other assertions.
+
+   Even code that isn't a test per se, but merely some setup code
+   should be inside a test assertion.
+
+ - Chain your test assertions
+
+   Write test code like this:
+
+	git merge foo &&
+	git push bar &&
+	test ...
+
+   Instead of:
+
+	git merge hla
+	git push gh
+	test ...
+
+   That way all of the commands in your tests will succeed or fail. If
+   you must ignore the return value of something, consider using a
+   helper function (e.g. use sane_unset instead of unset, in order
+   to avoid unportable return value for unsetting a variable that was
+   already unset), or prepending the command with test_might_fail or
+   test_must_fail.
+
+ - Check the test coverage for your tests. See the "Test coverage"
+   below.
+
+   Don't blindly follow test coverage metrics; if a new function you added
+   doesn't have any coverage, then you're probably doing something wrong,
+   but having 100% coverage doesn't necessarily mean that you tested
+   everything.
+
+   Tests that are likely to smoke out future regressions are better
+   than tests that just inflate the coverage metrics.
+
+ - When a test checks for an absolute path that a git command generated,
+   construct the expected value using $(pwd) rather than $PWD,
+   $TEST_DIRECTORY, or $TRASH_DIRECTORY. It makes a difference on
+   Windows, where the shell (MSYS bash) mangles absolute path names.
+   For details, see the commit message of 4114156ae9.
+
+Don't:
+
+ - exit() within a <script> part.
+
+   The harness will catch this as a programming error of the test.
+   Use test_done instead if you need to stop the tests early (see
+   "Skipping tests" below).
+
+ - use '! git cmd' when you want to make sure the git command exits
+   with failure in a controlled way by calling "die()".  Instead,
+   use 'test_must_fail git cmd'.  This will signal a failure if git
+   dies in an unexpected way (e.g. segfault).
+
+   On the other hand, don't use test_must_fail for running regular
+   platform commands; just use '! cmd'.  We are not in the business
+   of verifying that the world given to us sanely works.
+
+ - use perl without spelling it as "$PERL_PATH". This is to help our
+   friends on Windows where the platform Perl often adds CR before
+   the end of line, and they bundle Git with a version of Perl that
+   does not do so, whose path is specified with $PERL_PATH. Note that we
+   provide a "perl" function which uses $PERL_PATH under the hood, so
+   you do not need to worry when simply running perl in the test scripts
+   (but you do, for example, on a shebang line or in a sub script
+   created via "write_script").
+
+ - use sh without spelling it as "$SHELL_PATH", when the script can
+   be misinterpreted by broken platform shell (e.g. Solaris).
+
+ - chdir around in tests.  It is not sufficient to chdir to
+   somewhere and then chdir back to the original location later in
+   the test, as any intermediate step can fail and abort the test,
+   causing the next test to start in an unexpected directory.  Do so
+   inside a subshell if necessary.
+
+ - Break the TAP output
+
+   The raw output from your test may be interpreted by a TAP harness. TAP
+   harnesses will ignore everything they don't know about, but don't step
+   on their toes in these areas:
+
+   - Don't print lines like "$x..$y" where $x and $y are integers.
+
+   - Don't print lines that begin with "ok" or "not ok".
+
+   TAP harnesses expect a line that begins with either "ok" and "not
+   ok" to signal a test passed or failed (and our harness already
+   produces such lines), so your script shouldn't emit such lines to
+   their output.
+
+   You can glean some further possible issues from the TAP grammar
+   (see http://search.cpan.org/perldoc?TAP::Parser::Grammar#TAP_Grammar)
+   but the best indication is to just run the tests with prove(1),
+   it'll complain if anything is amiss.
+
+Keep in mind:
+
+ - Inside <script> part, the standard output and standard error
+   streams are discarded, and the test harness only reports "ok" or
+   "not ok" to the end user running the tests. Under --verbose, they
+   are shown to help debugging the tests.
+
+
+Skipping tests
+--------------
+
+If you need to skip tests you should do so by using the three-arg form
+of the test_* functions (see the "Test harness library" section
+below), e.g.:
+
+    test_expect_success PERL 'I need Perl' '
+        perl -e "hlagh() if unf_unf()"
+    '
+
+The advantage of skipping tests like this is that platforms that don't
+have the PERL and other optional dependencies get an indication of how
+many tests they're missing.
+
+If the test code is too hairy for that (i.e. does a lot of setup work
+outside test assertions) you can also skip all remaining tests by
+setting skip_all and immediately call test_done:
+
+	if ! test_have_prereq PERL
+	then
+	    skip_all='skipping perl interface tests, perl not available'
+	    test_done
+	fi
+
+The string you give to skip_all will be used as an explanation for why
+the test was skipped.

+		test_expect_code 1 git merge "merge msg" B master
+	'
+
+ - test_must_fail <git-command>
+
+   Run a git command and ensure it fails in a controlled way.  Use
+   this instead of "! <git-command>".  When git-command dies due to a
+   segfault, test_must_fail diagnoses it as an error; "! <git-command>"
+   treats it as just another expected failure, which would let such a
+   bug go unnoticed.
+
+ - test_might_fail <git-command>
+
+   Similar to test_must_fail, but tolerate success, too.  Use this
+   instead of "<git-command> || :" to catch failures due to segv.
+
+ - test_cmp <expected> <actual>
+
+   Check whether the content of the <actual> file matches the
+   <expected> file.  This behaves like "cmp" but produces more
+   helpful output when the test is run with "-v" option.
+
+ - test_line_count (= | -lt | -ge | ...) <length> <file>
+
+   Check whether a file has the length it is expected to.
+
+ - test_path_is_file <path> [<diagnosis>]
+   test_path_is_dir <path> [<diagnosis>]
+   test_path_is_missing <path> [<diagnosis>]
+
+   Check if the named path is a file, if the named path is a
+   directory, or if the named path does not exist, respectively,
+   and fail otherwise, showing the <diagnosis> text.
+
+ - test_when_finished <script>
+
+   Prepend <script> to a list of commands to run to clean up
+   at the end of the current test.  If some clean-up command
+   fails, the test will not pass.
+
+   Example:
+
+	test_expect_success 'branch pointing to non-commit' '
+		git rev-parse HEAD^{tree} >.git/refs/heads/invalid &&
+		test_when_finished "git update-ref -d refs/heads/invalid" &&
+		...
+	'
+
+ - test_write_lines <lines>
+
+   Write <lines> on standard output, one line per argument.
+   Useful to prepare multi-line files in a compact form.
+
+   Example:
+
+	test_write_lines a b c d e f g >foo
+
+   Is a more compact equivalent of:
+	cat >foo <<-EOF
+	a
+	b
+	c
+	d
+	e
+	f
+	g
+	EOF
+
+
+ - test_pause
+
+	This command is useful for writing and debugging tests and must be
+	removed before submitting. It halts the execution of the test and
+	spawns a shell in the trash directory. Exit the shell to continue
+	the test. Example:
+
+	test_expect_success 'test' '
+		git do-something >actual &&
+		test_pause &&
+		test_cmp expected actual
+	'
+
+ - test_ln_s_add <path1> <path2>
+
+   This function helps systems whose filesystem does not support symbolic
+   links. Use it to add a symbolic link entry to the index when it is not
+   important that the file system entry is a symbolic link, i.e., instead
+   of the sequence
+
+	ln -s foo bar &&
+	git add bar
+
+   Sometimes it is possible to split a test in a part that does not need
+   the symbolic link in the file system and a part that does; then only
+   the latter part need be protected by a SYMLINKS prerequisite (see below).
+
+Prerequisites
+-------------
+
+These are the prerequisites that the test library predefines with
+test_have_prereq.
+
+See the prereq argument to the test_* functions in the "Test harness
+library" section above and the "test_have_prereq" function for how to
+use these, and "test_set_prereq" for how to define your own.
+
+ - PYTHON
+
+   Git wasn't compiled with NO_PYTHON=YesPlease. Wrap any tests that
+   need Python with this.
+
+ - PERL
+
+   Git wasn't compiled with NO_PERL=YesPlease.
+
+   Even without the PERL prerequisite, tests can assume there is a
+   usable perl interpreter at $PERL_PATH, though it need not be
+   particularly modern.
+
+ - POSIXPERM
+
+   The filesystem supports POSIX style permission bits.
+
+ - BSLASHPSPEC
+
+   Backslashes in pathspec are not directory separators. This is not
+   set on Windows. See 6fd1106a for details.
+
+ - EXECKEEPSPID
+
+   The process retains the same pid across exec(2). See fb9a2bea for
+   details.
+
+ - PIPE
+
+   The filesystem we're on supports creation of FIFOs (named pipes)
+   via mkfifo(1).
+
+ - SYMLINKS
+
+   The filesystem we're on supports symbolic links. E.g. a FAT
+   filesystem doesn't support these. See 704a3143 for details.
+
+ - SANITY
+
+   Test is not run by root user, and an attempt to write to an
+   unwritable file is expected to fail correctly.
+
+ - LIBPCRE
+
+   Git was compiled with USE_LIBPCRE=YesPlease. Wrap any tests
+   that use git-grep --perl-regexp or git-grep -P in these.
+
+ - CASE_INSENSITIVE_FS
+
+   Test is run on a case insensitive file system.
+
+ - UTF8_NFD_TO_NFC
+
+   Test is run on a filesystem which converts decomposed utf-8 (nfd)
+   to precomposed utf-8 (nfc).

+
+Test coverage
+-------------
+
+You can use the coverage tests to find code paths that are not being
+used or properly exercised yet.
+
+To do that, run the coverage target at the top-level (not in the t/
+directory):
+
+    make coverage
+
+That'll compile Git with GCC's coverage arguments, and generate a test
+report with gcov after the tests finish. Running the coverage tests
+can take a while, since running the tests in parallel is incompatible
+with GCC's coverage mode.
+
+After the tests have run you can generate a list of untested
+functions:
+
+    make coverage-untested-functions
+
+You can also generate a detailed per-file HTML report using the
+Devel::Cover module. To install it do:
+
+   # On Debian or Ubuntu:
+   sudo aptitude install libdevel-cover-perl
+
+   # From the CPAN with cpanminus
+   curl -L http://cpanmin.us | perl - --sudo --self-upgrade
+   cpanm --sudo Devel::Cover
+
+Then, at the top-level:
+
+    make cover_db_html
+
+That'll generate a detailed cover report in the "cover_db_html"
+directory, which you can then copy to a webserver, or inspect locally
+in a browser.

+Git performance tests
+=====================
+
+This directory holds performance testing scripts for git tools.  The
+first part of this document describes the various ways in which you
+can run them.
+
+When fixing the tools or adding enhancements, you are strongly
+encouraged to add tests in this directory to cover what you are
+trying to fix or enhance.  The later part of this short document
+describes how your test scripts should be organized.
+
+
+Running Tests
+-------------
+
+The easiest way to run tests is to say "make".  This runs all
+the tests on the current git repository.
+
+    === Running 2 tests in this tree ===
+    [...]
+    Test                                     this tree
+    ---------------------------------------------------------
+    0001.1: rev-list --all                   0.54(0.51+0.02)
+    0001.2: rev-list --all --objects         6.14(5.99+0.11)
+    7810.1: grep worktree, cheap regex       0.16(0.16+0.35)
+    7810.2: grep worktree, expensive regex   7.90(29.75+0.37)
+    7810.3: grep --cached, cheap regex       3.07(3.02+0.25)
+    7810.4: grep --cached, expensive regex   9.39(30.57+0.24)
+
+You can compare multiple repositories and even git revisions with the
+'run' script:
+
+    $ ./run . origin/next /path/to/git-tree p0001-rev-list.sh
+
+where . stands for the current git tree.  The full invocation is
+
+    ./run [<revision|directory>...] [--] [<test-script>...]
+
+A '.' argument is implied if you do not pass any other
+revisions/directories.
+
+You can also manually test this or another git build tree, and then
+call the aggregation script to summarize the results:
+
+    $ ./p0001-rev-list.sh
+    [...]
+    $ GIT_BUILD_DIR=/path/to/other/git ./p0001-rev-list.sh
+    [...]
+    $ ./aggregate.perl . /path/to/other/git ./p0001-rev-list.sh
+
+aggregate.perl has the same invocation as 'run', it just does not run
+anything beforehand.
+
+You can set the following variables (also in your config.mak):
+
+    GIT_PERF_REPEAT_COUNT
+	Number of times a test should be repeated for best-of-N
+	measurements.  Defaults to 3.
+
+    GIT_PERF_MAKE_OPTS
+	Options to use when automatically building a git tree for
+	performance testing.  E.g., -j6 would be useful.
+
+    GIT_PERF_REPO
+    GIT_PERF_LARGE_REPO
+	Repositories to copy for the performance tests.  The normal
+	repo should be at least git.git size.  The large repo should
+	probably be about linux.git size for optimal results.
+	Both default to the git.git you are running from.
+
+You can also pass the options taken by ordinary git tests; the most
+useful one is:
+
+--root=<directory>::
+	Create "trash" directories used to store all temporary data during
+	testing under <directory>, instead of the t/ directory.
+	Using this option with a RAM-based filesystem (such as tmpfs)
+	can massively speed up the test suite.
+
+
+Naming Tests
+------------
+
+The performance test files are named as:
+
+	pNNNN-commandname-details.sh
+
+where N is a decimal digit.  The same conventions for choosing NNNN as
+for normal tests apply.
+
+
+Writing Tests
+-------------
+
+The perf script starts much like a normal test script, except it
+sources perf-lib.sh:
+
+	#!/bin/sh
+	#
+	# Copyright (c) 2005 Junio C Hamano
+	#
+
+	test_description='xxx performance test'
+	. ./perf-lib.sh
+
+After that you will want to use some of the following:
+
+	test_perf_default_repo  # sets up a "normal" repository
+	test_perf_large_repo    # sets up a "large" repository
+
+	test_perf_default_repo sub  # ditto, in a subdir "sub"
+
+        test_checkout_worktree  # if you need the worktree too
+
+At least one of the first two is required!
+
+You can use test_expect_success as usual.  For actual performance
+tests, use
+
+	test_perf 'descriptive string' '
+		command1 &&
+		command2
+	'
+
+test_perf spawns a subshell, for lack of better options.  This means
+that
+
+* you _must_ export all variables that you need in the subshell
+
+* you _must_ flag all variables that you want to persist from the
+  subshell with 'test_export':
+
+	test_perf 'descriptive string' '
+		foo=$(git rev-parse HEAD) &&
+		test_export foo
+	'
+
+  The so-exported variables are automatically marked for export in the
+  shell executing the perf test.  For your convenience, test_export is
+  the same as export in the main shell.
+
+  This feature relies on a bit of magic using 'set' and 'source'.
+  While we have tried to make sure that it can cope with embedded
+  whitespace and other special characters, it will not work with
+  multi-line data.

+The url data files in this directory contain URLs with characters

+A select few characters in the 0x01-0x1f range are skipped to help

+
+This is a tool for authors of external helper tools to sanity-check
+their helpers. If you have written the "git-credential-foo" helper,
+you check it with:
+
+  make GIT_TEST_CREDENTIAL_HELPER=foo t0303-credential-external.sh
+
+This assumes that your helper is capable of both storing and
+retrieving credentials (some helpers may be read-only, and they will
+fail these tests).
+
+Please note that the individual tests do not verify all of the
+preconditions themselves, but rather build on each other. A failing
+test means that tests later in the sequence can return false "OK"
+results.
+
+If your helper supports time-based expiration with a configurable
+timeout, you can test that feature with:
+
+  make GIT_TEST_CREDENTIAL_HELPER=foo \
+       GIT_TEST_CREDENTIAL_HELPER_TIMEOUT="foo --timeout=1" \
+       t0303-credential-external.sh
+
+If your helper requires additional setup before the tests are started,
+you can set GIT_TEST_CREDENTIAL_HELPER_SETUP to a sequence of shell
+commands.

+test_description="Tests of cwd/prefix/worktree/gitdir setup in all cases
+
+A few rules for repo setup:
+
+1. GIT_DIR is relative to user's cwd. --git-dir is equivalent to
+   GIT_DIR.
+
+2. .git file is relative to parent directory. .git file is basically
+   symlink in disguise. The directory where .git file points to will
+   become new git_dir.
+
+3. core.worktree is relative to git_dir.
+
+4. GIT_WORK_TREE is relative to user's cwd. --work-tree is
+   equivalent to GIT_WORK_TREE.
+
+5. GIT_WORK_TREE/core.worktree was originally meant to work only if
+   GIT_DIR is set, but earlier git didn't enforce it, and some scripts
+   depend on the implementation that happened to first discover .git by
+   going up from the users $cwd and then using the specified working tree
+   that may or may not have any relation to where .git was found in.  This
+   historical behaviour must be kept.
+
+6. Effective GIT_WORK_TREE overrides core.worktree and core.bare
+
+7. Effective core.worktree conflicts with core.bare
+
+8. If GIT_DIR is set but neither worktree nor bare setting is given,
+   original cwd becomes worktree.
+
+9. If .git discovery is done inside a repo, the repo becomes a bare
+   repo. .git discovery is performed if GIT_DIR is not set.
+
+10. If no worktree is available, cwd remains unchanged, prefix is
+    NULL.
+
+11. When user's cwd is outside worktree, cwd remains unchanged,
+    prefix is NULL.

+
+Create blobs, trees, commits and a tag that all share the same
+prefix, and make sure "git rev-parse" can take advantage of
+type information to disambiguate short object names that are
+not necessarily unique.
+
+The final history used in the test has five commits, with the bottom
+one tagged as v1.0.0.  They all have one regular file each.

+	    justice and holiness and is the nurse of his age and the
+	    companion of his journey;--hope which is mightiest to sway
+	    the restless soul of man.
+
+	How admirable are his words!  And the great blessing of riches, I do
+	not say to every man, but to a good man, is, that he has had no
+	occasion to deceive or to defraud others, either intentionally or
+	unintentionally; and when he departs to the world below he is not in
+	any apprehension about offerings due to the gods or debts which he owes
+	to men.  Now to this peace of mind the possession of wealth greatly
+	contributes; and therefore I say, that, setting one thing against
+	another, of the many advantages which wealth has to give, to a man of
+	sense this is in my opinion the greatest.
+
+	Well said, Cephalus, I replied; but as concerning justice, what is
+	it?--to speak the truth and to pay your debts--no more than this?  And
+	even to this are there not exceptions?  Suppose that a friend when in
+	his right mind has deposited arms with me and he asks for them when he
+	is not in his right mind, ought I to give them back to him?  No one
+	would say that I ought or that I should be right in doing so, any more
+	than they would say that I ought always to speak the truth to one who
+	is in his condition.
+
+	You are quite right, he replied.
+
+	But then, I said, speaking the truth and paying your debts is not a
+	correct definition of justice.
+
+	CEPHALUS - SOCRATES - POLEMARCHUS
+
+	Quite correct, Socrates, if Simonides is to be believed, said
+	Polemarchus interposing.
+
+	I fear, said Cephalus, that I must go now, for I have to look after the
+	sacrifices, and I hand over the argument to Polemarchus and the company.

+How to write RIGHT test cases
+=============================
+
+Insert the word "ChangeMe" (exactly this form) at a distance of
+at least two lines from the line that must appear in the hunk header.
+
+The text that must appear in the hunk header must contain the word
+"right", but in all upper-case, like in the title above.
+
+To mark a test case that highlights a malfunction, insert the word
+BROKEN in all lower-case somewhere in the file.
+
+This text is a bit twisted and out of order, but it is itself a
+test case for the default hunk header pattern. Know what you are doing
+if you change it.
+
+BTW, this tests that the head line goes to the hunk header, not the line
+of equal signs.

+# arbitrary path gets renamed between X-D to "newname" and X-E also to
+# "newname" to resolve it as both sides renaming it to the same new
+# name. It is akin to what we do at the content level, i.e. "B and C do not
+# agree what the final contents should be, so we leave the conflict marker
+# but that may cancel out at the final merge stage".

+#
+# This test covers the handling of objects which might have old
+# mtimes in the filesystem (because they were used previously)
+# and are just now becoming referenced again.
+#
+# We're going to do two things that are a little bit "fake" to
+# help make our simulation easier:
+#
+#   1. We'll turn off reflogs. You can still run into
+#      problems with reflogs on, but your objects
+#      don't get pruned until both the reflog expiration
+#      has passed on their references, _and_ they are out
+#      of prune's expiration period. Dropping reflogs
+#      means we only have to deal with one variable in our tests,
+#      but the results generalize.
+#
+#   2. We'll use a temporary index file to create our
+#      works-in-progress. Most workflows would mention
+#      referenced objects in the index, which prune takes
+#      into account. However, many operations don't. For
+#      example, a partial commit with "git commit foo"
+#      will use a temporary index. Or they may not need
+#      an index at all (e.g., creating a new commit
+#      to refer to an existing tree).

+#  - Hard coded "lines: +2 -3" placeholder, instead of real numbers.
+#  - CVS normally does not internally add a blank first line
+#    or a last line with nothing but a space to log messages.
+#  - The latest cvs 1.12.x server sends +0000 timezone (with some hidden "MT"
+#    tagging in the protocol), and if cvs 1.12.x client sees the MT tags,
+#    it converts to local time zone.  git-cvsserver doesn't do the +0000
+#    or the MT tags...
+#  - The latest 1.12.x releases add a "commitid:" field on to the end of the
+#    "date:" line (after "lines:").  Maybe we could stick git's commit id
+#    in it?  Or does CVS expect a certain number of bits (too few for
+#    a full sha1)?
+#
+# Given the above, expect the following test to break if git-cvsserver's
+# log output is improved.  The test is just to ensure it doesn't
+# accidentally get worse.

+line_buffer API
+===============
+
+The line_buffer library provides a convenient interface for
+mostly-line-oriented input.
+
+Each line is not permitted to exceed 10000 bytes.  The provided
+functions are not thread-safe or async-signal-safe, and like
+`fgets()`, they generally do not function correctly if interrupted
+by a signal without SA_RESTART set.
+
+Calling sequence
+----------------
+
+The calling program:
+
+ - initializes a `struct line_buffer` to LINE_BUFFER_INIT
+ - specifies a file to read with `buffer_init`
+ - processes input with `buffer_read_line`, `buffer_skip_bytes`,
+   and `buffer_copy_bytes`
+ - closes the file with `buffer_deinit`, perhaps to start over and
+   read another file.
+
+When finished, the caller can use `buffer_reset` to deallocate
+resources.
+
+Using temporary files
+---------------------
+
+Temporary files provide a place to store data that should not outlive
+the calling program.  A program
+
+ - initializes a `struct line_buffer` to LINE_BUFFER_INIT
+ - requests a temporary file with `buffer_tmpfile_init`
+ - acquires an output handle by calling `buffer_tmpfile_rewind`
+ - uses standard I/O functions like `fprintf` and `fwrite` to fill
+   the temporary file
+ - declares writing is over with `buffer_tmpfile_prepare_to_read`
+ - can re-read what was written with `buffer_read_line`,
+   `buffer_copy_bytes`, and so on
+ - can reuse the temporary file by calling `buffer_tmpfile_rewind`
+   again
+ - removes the temporary file with `buffer_deinit`, perhaps to
+   reuse the line_buffer for some other file.
+
+When finished, the calling program can use `buffer_reset` to deallocate
+resources.
+
+Functions
+---------
+
+`buffer_init`, `buffer_fdinit`::
+	Open the named file or file descriptor for input.
+	buffer_init(buf, NULL) prepares to read from stdin.
+	On failure, returns -1 (with errno indicating the nature
+	of the failure).
+
+`buffer_deinit`::
+	Stop reading from the current file (closing it unless
+	it was stdin).  Returns nonzero if `fclose` fails or
+	the error indicator was set.
+
+`buffer_read_line`::
+	Read a line and strip off the trailing newline.
+	On failure or end of file, returns NULL.
+
+`buffer_copy_bytes`::
+	Read `len` bytes of input and dump them to the standard output
+	stream.  Returns early for error or end of file.
+
+`buffer_skip_bytes`::
+	Discards `len` bytes from the input stream (stopping early
+	if necessary because of an error or eof).  Return value is
+	the number of bytes successfully read.
+
+`buffer_reset`::
+	Deallocates non-static buffers.
