+

+
+* "git checkout $tree" did not trigger an error.
+

+
+* "git describe --all" complained when a commit is described with a tag,
+ which was nonsense.
+
+* "git diff --no-index --" did not trigger no-index (aka "use git-diff as
+ a replacement of diff on untracked files") behaviour.
+
+* "git format-patch -1 HEAD" on a root commit failed to produce patch
+ text.
+
+* "git fsck branch" did not work as advertised; instead it behaved the same
+ way as "git fsck".
+
+* "git log --pretty=format:%s" did not handle a multi-line subject the
+ same way as built-in log listers (i.e. shortlog, --pretty=oneline, etc.)
+
+* "git daemon", and "git merge-file" are more careful when freopen fails
+ and barf, instead of going on and writing to unopened filehandle.
+
+* "git http-push" did not like some RFC 4918 compliant DAV server
+ responses.
+
+* "git merge -s recursive" mistakenly overwritten an untracked file in the
+ work tree upon delete/modify conflict.
+
+* "git merge -s recursive" didn't leave the index unmerged for entries with
+ rename/delete conflicts.
+
+* "git merge -s recursive" clobbered untracked files in the work tree.
+
+* "git mv -k" with more than one erroneous paths misbehaved.
+
+* "git read-tree -m -u" hence branch switching incorrectly lost a
+ subdirectory in rare cases.
+
+* "git rebase -i" issued an unnecessary error message upon a user error of
+ marking the first commit to be "squash"ed.
+
+* "git shortlog" did not format a commit message with multi-line
+ subject correctly.
+
+Many documentation updates.

+GIT v1.6.1.2 Release Notes
+==========================
+
+Fixes since v1.6.1.1
+--------------------
+
+* The logic for rename detection in internal diff used by commands like
+ "git diff" and "git blame" has been optimized to avoid loading the same
+ blob repeatedly.
+
+* We did not allow writing out a blob that is larger than 2GB for no good
+ reason.
+
+* "git format-patch -o $dir", when $dir is a relative directory, used it
+ as relative to the root of the work tree, not relative to the current
+ directory.
+
+* v1.6.1 introduced an optimization for "git push" into a repository (A)
+ that borrows its objects from another repository (B) to avoid sending
+ objects that are available in repository B, when they are not yet used
+ by repository A. However the code on the "git push" sender side was
+ buggy and did not work when repository B had new objects that are not
+ known by the sender. This caused pushing into a "forked" repository
+ served by v1.6.1 software using "git push" from v1.6.1 sometimes did not
+ work. The bug was purely on the "git push" sender side, and has been
+ corrected.
+
+* "git status -v" did not paint its diff output in colour even when
+ color.ui configuration was set.
+
+* "git ls-tree" learned --full-tree option to help Porcelain scripts that
+ want to always see the full path regardless of the current working
+ directory.
+
+* "git grep" incorrectly searched in work tree paths even when they are
+ marked as assume-unchanged. It now searches in the index entries.
+
+* "git gc" with no grace period needlessly ejected packed but unreachable
+ objects in their loose form, only to delete them right away.

+
+* "git grep" did not pass the -I (ignore binary) option when

+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 merge -s $strategy" can use a custom built strategy if you have a

+
+* "git pull" (and "git fetch") can be told to operate "-v"erbosely or

+
+* "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

+
+* "git remote show $remote" lists remote branches one-per-line now.

+ generate patches for the given revision range.
+
+* "git submodule foreach" subcommand allows you to iterate over checked

+ 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 v1.6.2 Release Notes
+========================
+
+With the next major release, "git push" into a branch that is
+currently checked out will be refused by default. You can choose
+what should happen upon such a push by setting the configuration
+variable receive.denyCurrentBranch in the receiving repository.
+
+To ease the transition plan, the receiving repository of such a
+push running this release will issue a big warning when the
+configuration variable is missing. 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 plan.
+
+For a similar reason, "git push $there :$killed" to delete the branch
+$killed in a remote repository $there, if $killed branch is the current
+branch pointed at by its HEAD, gets a large warning. You can choose what
+should happen upon such a push by setting the configuration variable
+receive.denyDeleteCurrent in the receiving repository.
+
+
+Updates since v1.6.1
+--------------------
+
+(subsystems)
+
+* git-svn updates.
+
+* gitweb updates, including a new patch view and RSS/Atom feed
+ improvements.
+
+* (contrib/emacs) git.el now has commands for checking out a branch,
+ creating a branch, cherry-picking and reverting commits; vc-git.el
+ is not shipped with git anymore (it is part of official Emacs).
+
+(performance)
+
+* pack-objects autodetects the number of CPUs available and uses threaded
+ version.
+
+(usability, bells and whistles)
+
+* automatic typo correction works on aliases as well
+
+* @{-1} is a way to refer to the last branch you were on. This is
+ accepted not only where an object name is expected, but anywhere
+ a branch name is expected and acts as if you typed the branch name.
+ E.g. "git branch --track mybranch @{-1}", "git merge @{-1}", and
+ "git rev-parse --symbolic-full-name @{-1}" would work as expected.
+
+* When refs/remotes/origin/HEAD points at a remote tracking branch that
+ has been pruned away, many git operations issued warning when they
+ internally enumerated the refs. We now warn only when you say "origin"
+ to refer to that pruned branch.
+
+* The location of .mailmap file can be configured, and its file format was
+ enhanced to allow mapping an incorrect e-mail field as well.
+
+* "git add -p" learned 'g'oto action to jump directly to a hunk.
+
+* "git add -p" learned to find a hunk with given text with '/'.
+
+* "git add -p" optionally can be told to work with just the command letter
+ without Enter.
+
+* when "git am" stops upon a patch that does not apply, it shows the
+ title of the offending patch.
+
+* "git am --directory=<dir>" and "git am --reject" passes these options
+ to underlying "git apply".
+
+* "git am" learned --ignore-date option.
+
+* "git blame" aligns author names better when they are spelled in
+ non US-ASCII encoding.
+
+* "git clone" now makes its best effort when cloning from an empty
+ repository to set up configuration variables to refer to the remote
+ repository.
+
+* "git checkout -" is a shorthand for "git checkout @{-1}".
+
+* "git cherry" defaults to whatever the current branch is tracking (if
+ exists) when the <upstream> argument is not given.
+
+* "git cvsserver" can be told not to add extra "via git-CVS emulator" to
+ the commit log message it serves via gitcvs.commitmsgannotation
+ configuration.
+
+* "git cvsserver" learned to handle 'noop' command some CVS clients seem
+ to expect to work.
+
+* "git diff" learned a new option --inter-hunk-context to coalesce close
+ hunks together and show context between them.
+
+* The definition of what constitutes a word for "git diff --color-words"
+ can be customized via gitattributes, command line or a configuration.
+
+* "git diff" learned --patience to run "patience diff" algorithm.
+
+* "git filter-branch" learned --prune-empty option that discards commits
+ that do not change the contents.
+
+* "git fsck" now checks loose objects in alternate object stores, instead
+ of misreporting them as missing.
+
+* "git gc --prune" was resurrected to allow "git gc --no-prune" and
+ giving non-default expiration period e.g. "git gc --prune=now".
+
+* "git grep -w" and "git grep" for fixed strings have been optimized.
+
+* "git mergetool" learned -y(--no-prompt) option to disable prompting.
+
+* "git rebase -i" can transplant a history down to root to elsewhere
+ with --root option.
+
+* "git reset --merge" is a new mode that works similar to the way
+ "git checkout" switches branches, taking the local changes while
+ switching to another commit.
+
+* "git submodule update" learned --no-fetch option.
+
+* "git tag" learned --contains that works the same way as the same option
+ from "git branch".
+
+
+Fixes since v1.6.1
+------------------
+
+All of the fixes in v1.6.1.X maintenance series are included in this
+release, unless otherwise noted.
+
+Here are fixes that this release has, but have not been backported to
+v1.6.1.X series.
+
+* "git-add sub/file" when sub is a submodule incorrectly added the path to
+ the superproject.
+
+* "git bundle" did not exclude annotated tags even when a range given
+ from the command line wanted to.
+
+* "git filter-branch" unnecessarily refused to work when you had
+ checked out a different commit from what is recorded in the superproject
+ index in a submodule.
+
+* "git filter-branch" incorrectly tried to update a nonexistent work tree
+ at the end when it is run in a bare repository.
+
+* "git gc" did not work if your repository was created with an ancient git
+ and never had any pack files in it before.
+
+* "git mergetool" used to ignore autocrlf and other attributes
+ based content rewriting.
+
+* branch switching and merges had a silly bug that did not validate
+ the correct directory when making sure an existing subdirectory is
+ clean.
+
+* "git -p cmd" when cmd is not a built-in one left the display in funny state
+ when killed in the middle.

(A Large Angry SCM)
+By default, Thunderbird will both wrap emails as well as flag them as

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):

+To bootstrap the process, you can first create a bundle that does not have
+any basis. You can use a tag to remember up to what commit you last
+processed, in order to make it easy to later update the other repository

-+
-This is useful when sending the whole history.
+----------------
+machineA$ cd R1
+machineA$ git bundle create file.bundle master
+machineA$ git tag -f lastR2bundle master
+----------------
-------------
-$ git bundle create mybundle master
-------------
+Then you transfer file.bundle to the target machine B. If you are creating
+the repository on machine B, then you can clone from the bundle as if it
+were a remote repository instead of creating an empty repository and then
+pulling or fetching objects from the bundle:
-- Using temporally tags.
-+
-We set a tag in R1 (lastR2bundle) after the previous such transport,
-and move it afterwards to help build the bundle.
+----------------
+machineB$ git clone /home/me/tmp/file.bundle R2
+----------------
-------------
-$ git bundle create mybundle master ^lastR2bundle
-$ git tag -f lastR2bundle master
-------------
+This will define a remote called "origin" in the resulting repository that
+lets you fetch and pull from the bundle. The $GIT_DIR/config file in R2 will
+have an entry like this:
-- Using a tag present in both repositories
+------------------------
+[remote "origin"]
+ url = /home/me/tmp/file.bundle
+ fetch = refs/heads/*:refs/remotes/origin/*
+------------------------
+
+To update the resulting mine.git repository, you can fetch or pull after
+replacing the bundle stored at /home/me/tmp/file.bundle with incremental
+updates.
+
+After working some more in the original repository, you can create an
+incremental bundle to update the other repository:
+
+----------------
+machineA$ cd R1
+machineA$ git bundle create file.bundle lastR2bundle..master
+machineA$ git tag -f lastR2bundle master
+----------------
+
+You then transfer the bundle to the other machine to replace
+/home/me/tmp/file.bundle, and pull from it.
+
+----------------
+machineB$ cd R2
+machineB$ git pull
+----------------
-------------
-$ git bundle create mybundle master ^v1.0.0
-------------
+If you know up to what commit the intended recipient repository should
+have the necessary objects, you can use that knowledge to specify the
+basis, giving a cut-off point to limit the revisions and objects that go
+in the resulting bundle. The previous example used lastR2bundle tag
+for this purpose, but you can use any other options that you would give to
+the linkgit:git-log[1] command. Here are more examples:
-- A basis based on time.
+You can use a tag that is present in both:
-------------
-$ git bundle create mybundle master --since=10.days.ago
-------------
+----------------
+$ git bundle create mybundle v1.0.0..master
+----------------
-- With a limit on the number of commits
+You can use a basis based on time:
-------------
-$ git bundle create mybundle master -n 10
-------------
+----------------
+$ git bundle create mybundle --since=10.days master
+----------------
-Then you move mybundle from A to B, and in R2 on B:
+You can use the number of commits:
-------------
+----------------
+$ git bundle create mybundle -10 master
+----------------
+
+You can run `git-bundle verify` to see if you can extract from a bundle
+that was created with a basis:
+
+----------------
$ git bundle verify mybundle
-$ git fetch mybundle master:localRef
-------------
+----------------
-With something like this in the config in R2:
+This will list what commits you must have in order to extract from the
+bundle and will error out if you do not have them.
-------------------------
-[remote "bundle"]
- url = /home/me/tmp/file.bdl
- fetch = refs/heads/*:refs/remotes/origin/*

+A bundle from a recipient repository's point of view is just like a

---------------------------------------------------------------
+
+Checklist for Shrinking a Repository
+------------------------------------
+
+git-filter-branch is often used to get rid of a subset of files,
+usually with some combination of `\--index-filter` and
+`\--subdirectory-filter`. People expect the resulting repository to
+be smaller than the original, but you need a few more steps to
+actually make it smaller, because git tries hard not to lose your
+objects until you tell it to. First make sure that:
+
+* You really removed all variants of a filename, if a blob was moved
+ over its lifetime. `git log \--name-only \--follow \--all \--
+ filename` can help you find renames.
+
+* You really filtered all refs: use `\--tag-name-filter cat \--
+ \--all` when calling git-filter-branch.
+
+Then there are two ways to get a smaller repository. A safer way is
+to clone, that keeps your original intact.
+
+* Clone it with `git clone +++file:///path/to/repo+++`. The clone
+ will not have the removed objects. See linkgit:git-clone[1]. (Note
+ that cloning with a plain path just hardlinks everything!)
+
+If you really don't want to clone it, for whatever reasons, check the
+following points instead (in this order). This is a very destructive
+approach, so *make a backup* or go back to cloning it. You have been
+warned.
+
+* Remove the original refs backed up by git-filter-branch: say `git
+ for-each-ref \--format="%(refname)" refs/original/ | xargs -n 1 git
+ update-ref -d`.
+
+* Expire all reflogs with `git reflog expire \--expire=now \--all`.
+
+* Garbage collect all unreferenced objects with `git gc \--prune=now`
+ (or if your git-gc is not new enough to support arguments to
+ `\--prune`, use `git repack -ad; git prune` instead).

-the parent relationship.
+'git-merge-base' finds best common ancestor(s) between two commits to use

+ancestor if the latter is an ancestor of the former. A common ancestor
+that does not have any better common ancestor is a 'best common
+ancestor', i.e. a 'merge base'. Note that there can be more than one
+merge base for a pair of commits.

-The 'git-merge-base' algorithm is still in flux - use the source...

+
+Given three commits 'A', 'B' and 'C', `git merge-base A B C` will compute the
+merge base between 'A' and a hypothetical commit 'M', which is a merge
+between 'B' and 'C'. For example, with this topology:
+
+ o---o---o---o---C
+ /
+ / o---o---o---B
+ / /
+ ---2---1---o---o---o---A
+
+the result of `git merge-base A B C` is '1'. This is because the

+
+
+ o---o---o---o---o
+ / \
+ / o---o---o---o---M
+ / /
+ ---2---1---o---o---o---A
+
+and the result of `git merge-base A M` is '1'. Commit '2' is also a
+common ancestor between 'A' and 'M', but '1' is a better common ancestor,
+because '2' is an ancestor of '1'. Hence, '2' is not a merge base.
+
+When the history involves criss-cross merges, there can be more than one
+'best' common ancestor for two commits. For example, with this topology:
+
+ ---1---o---A
+ \ /
+ X
+ / \
+ ---2---o---o---B
+
+both '1' and '2' are merge-bases of A and B. Neither one is better than
+the other (both are 'best' merge bases). When the `--all` option is not given,
+it is unspecified which best one is output.

i.e. matching `HEAD`.
+HOW CONFLICTS ARE PRESENTED
+---------------------------
+
+During a merge, the working tree files are updated to reflect the result
+of the merge. Among the changes made to the common ancestor's version,
+non-overlapping ones (that is, you changed an area of the file while the
+other side left that area intact, or vice versa) are incorporated in the
+final result verbatim. When both sides made changes to the same area,
+however, git cannot randomly pick one side over the other, and asks you to
+resolve it by leaving what both sides did to that area.
+
+By default, git uses the same style as that is used by "merge" program
+from the RCS suite to present such a conflicted hunk, like this:
+
+------------
+Here are lines that are either unchanged from the common
+ancestor, or cleanly resolved because only one side changed.
+<<<<<<< yours:sample.txt
+Conflict resolution is hard;
+let's go shopping.
+=======
+Git makes conflict resolution easy.
+>>>>>>> theirs:sample.txt
+And here is another line that is cleanly resolved or unmodified.
+------------
+
+The area where a pair of conflicting changes happened is marked with markers
+"`<<<<<<<`", "`=======`", and "`>>>>>>>`". The part before the "`=======`"
+is typically your side, and the part afterwards is typically their side.
+
+The default format does not show what the original said in the conflicting
+area. You cannot tell how many lines are deleted and replaced with
+Barbie's remark on your side. The only thing you can tell is that your
+side wants to say it is hard and you'd prefer to go shopping, while the
+other side wants to claim it is easy.
+
+An alternative style can be used by setting the "merge.conflictstyle"
+configuration variable to "diff3". In "diff3" style, the above conflict
+may look like this:
+
+------------
+Here are lines that are either unchanged from the common
+ancestor, or cleanly resolved because only one side changed.
+<<<<<<< yours:sample.txt
+Conflict resolution is hard;
+let's go shopping.
+|||||||
+Conflict resolution is hard.
+=======
+Git makes conflict resolution easy.
+>>>>>>> theirs:sample.txt
+And here is another line that is cleanly resolved or unmodified.
+------------
+
+In addition to the "`<<<<<<<`", "`=======`", and "`>>>>>>>`" markers, it uses
+another "`|||||||`" marker that is followed by the original text. You can
+tell that the original just stated a fact, and your side simply gave in to
+that statement and gave up, while the other side tried to have a more
+positive attitude. You can sometimes come up with a better resolution by
+viewing the original.
+
+
+HOW TO RESOLVE CONFLICTS
+------------------------
+
After seeing a conflict, you can do two things:
- * Decide not to merge. The only clean-up you need are to reset
+ * Decide not to merge. The only clean-ups you need are to reset
the index file to the `HEAD` commit to reverse 2. and to clean
up working tree changes made by 2. and 3.; 'git-reset --hard' can
be used for this.
- * Resolve the conflicts. `git diff` would report only the
- conflicting paths because of the above 2. and 3.
- Edit the working tree files into a desirable shape
- ('git mergetool' can ease this task), 'git-add' or 'git-rm'
- them, to make the index file contain what the merge result
- should be, and run 'git-commit' to commit the result.
+ * Resolve the conflicts. Git will mark the conflicts in
+ the working tree. Edit the files into shape and
+ 'git-add' them to the index. Use 'git-commit' to seal the deal.
+
+You can work through the conflict with a number of tools:
+
+ * Use a mergetool. 'git mergetool' to launch a graphical
+ mergetool which will work you through the merge.
+
+ * Look at the diffs. 'git diff' will show a three-way diff,
+ highlighting changes from both the HEAD and remote versions.
+
+ * Look at the diffs on their own. 'git log --merge -p <path>'
+ will show diffs first for the HEAD version and then the
+ remote version.
+ * Look at the originals. 'git show :1:filename' shows the
+ common ancestor, 'git show :2:filename' shows the HEAD
+ version and 'git show :3:filename' shows the remote version.

+RECOVERING FROM UPSTREAM REBASE
+-------------------------------
+
+Rebasing (or any other form of rewriting) a branch that others have
+based work on is a bad idea: anyone downstream of it is forced to
+manually fix their history. This section explains how to do the fix
+from the downstream's point of view. The real fix, however, would be
+to avoid rebasing the upstream in the first place.
+
+To illustrate, suppose you are in a situation where someone develops a
+'subsystem' branch, and you are working on a 'topic' that is dependent
+on this 'subsystem'. You might end up with a history like the
+following:
+
+------------
+ o---o---o---o---o---o---o---o---o master
+ \
+ o---o---o---o---o subsystem
+ \
+ *---*---* topic
+------------

+If 'subsystem' is rebased against 'master', the following happens:

+to 'subsystem', the commits from 'subsystem' will remain duplicated forever:
+
+------------
+ o---o---o---o---o---o---o---o master
+ \ \
+ o---o---o---o---o o'--o'--o'--o'--o'--M subsystem
+ \ /
+ *---*---*-..........-*--* topic
+------------
+
+Such duplicates are generally frowned upon because they clutter up
+history, making it harder to follow. To clean things up, you need to
+transplant the commits on 'topic' to the new 'subsystem' tip, i.e.,
+rebase 'topic'. This becomes a ripple effect: anyone downstream from
+'topic' is forced to rebase too, and so on!
+
+There are two kinds of fixes, discussed in the following subsections:
+
+Easy case: The changes are literally the same.::
+
+ This happens if the 'subsystem' rebase was a simple rebase and
+ had no conflicts.
+
+Hard case: The changes are not the same.::
+
+ This happens if the 'subsystem' rebase had conflicts, or used
+ `\--interactive` to omit, edit, or squash commits; or if the
+ upstream used one of `commit \--amend`, `reset`, or
+ `filter-branch`.
+
+
+The easy case
+~~~~~~~~~~~~~
+
+Only works if the changes (patch IDs based on the diff contents) on
+'subsystem' are literally the same before and after the rebase
+'subsystem' did.
+
+In that case, the fix is easy because 'git-rebase' knows to skip
+changes that are already present in the new upstream. So if you say
+(assuming you're on 'topic')
+------------
+ $ git rebase subsystem
+------------
+you will end up with the fixed history
+------------
+ o---o---o---o---o---o---o---o master
+ \
+ o'--o'--o'--o'--o' subsystem
+ \
+ *---*---* topic
+------------
+
+
+The hard case
+~~~~~~~~~~~~~
+
+Things get more complicated if the 'subsystem' changes do not exactly
+correspond to the ones before the rebase.
+
+NOTE: While an "easy case recovery" sometimes appears to be successful
+ even in the hard case, it may have unintended consequences. For
+ example, a commit that was removed via `git rebase
+ \--interactive` will be **resurrected**!
+
+The idea is to manually tell 'git-rebase' "where the old 'subsystem'
+ended and your 'topic' began", that is, what the old merge-base
+between them was. You will have to find a way to name the last commit
+of the old 'subsystem', for example:
+
+* With the 'subsystem' reflog: after 'git-fetch', the old tip of
+ 'subsystem' is at `subsystem@\{1}`. Subsequent fetches will
+ increase the number. (See linkgit:git-reflog[1].)
+
+* Relative to the tip of 'topic': knowing that your 'topic' has three
+ commits, the old tip of 'subsystem' must be `topic~3`.
+
+You can then transplant the old `subsystem..topic` to the new tip by
+saying (for the reflog case, and assuming you are on 'topic' already):
+------------
+ $ git rebase --onto subsystem subsystem@{1}
+------------
+
+The ripple effect of a "hard case" recovery is especially bad:
+'everyone' downstream from 'topic' will now have to perform a "hard
+case" recovery too!

+in the "diff.*.wordRegex" configuration variable. For example, in TeX
+a backslash followed by a sequence of letters forms a command, but
+several such commands can be run together without intervening
+whitespace. To separate them, use a regular expression such as

+
+Performing text diffs of binary files
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Sometimes it is desirable to see the diff of a text-converted
+version of some binary files. For example, a word processor
+document can be converted to an ASCII text representation, and
+the diff of the text shown. Even though this conversion loses
+some information, the resulting diff is useful for human
+viewing (but cannot be applied directly).
+
+The `textconv` config option is used to define a program for
+performing such a conversion. The program should take a single
+argument, the name of a file to convert, and produce the
+resulting text on stdout.
+
+For example, to show the diff of the exif information of a
+file instead of the binary information (assuming you have the
+exif tool installed):
+
+------------------------
+[diff "jpg"]
+ textconv = exif
+------------------------
+
+NOTE: The text conversion is generally a one-way conversion;
+in this example, we lose the actual image contents and focus
+just on the text data. This means that diffs generated by
+textconv are _not_ suitable for applying. For this reason,
+only `git diff` and the `git log` family of commands (i.e.,
+log, whatchanged, show) will perform text conversion. `git
+format-patch` will never generate this output. If you want to
+send somebody a text-converted diff of a binary file (e.g.,
+because it quickly conveys the changes you have made), you
+should generate it separately and send it as a comment _in
+addition to_ the usual binary diff that you might send.

+===============
+
+NAME
+----
+gitworkflows - An overview of recommended workflows with git
+
+SYNOPSIS
+--------
+git *
+
+
+DESCRIPTION
+-----------
+
+This document attempts to write down and motivate some of the workflow
+elements used for `git.git` itself. Many ideas apply in general,
+though the full workflow is rarely required for smaller projects with
+fewer people involved.
+
+We formulate a set of 'rules' for quick reference, while the prose
+tries to motivate each of them. Do not always take them literally;
+you should value good reasons for your actions higher than manpages
+such as this one.
+
+
+SEPARATE CHANGES
+----------------
+
+As a general rule, you should try to split your changes into small
+logical steps, and commit each of them. They should be consistent,
+working independently of any later commits, pass the test suite, etc.
+This makes the review process much easier, and the history much more
+useful for later inspection and analysis, for example with
+linkgit:git-blame[1] and linkgit:git-bisect[1].
+
+To achieve this, try to split your work into small steps from the very
+beginning. It is always easier to squash a few commits together than
+to split one big commit into several. Don't be afraid of making too
+small or imperfect steps along the way. You can always go back later
+and edit the commits with `git rebase \--interactive` before you
+publish them. You can use `git stash save \--keep-index` to run the
+test suite independent of other uncommitted changes; see the EXAMPLES
+section of linkgit:git-stash[1].
+
+
+MANAGING BRANCHES
+-----------------
+
+There are two main tools that can be used to include changes from one
+branch on another: linkgit:git-merge[1] and
+linkgit:git-cherry-pick[1].
+
+Merges have many advantages, so we try to solve as many problems as
+possible with merges alone. Cherry-picking is still occasionally
+useful; see "Merging upwards" below for an example.
+
+Most importantly, merging works at the branch level, while
+cherry-picking works at the commit level. This means that a merge can
+carry over the changes from 1, 10, or 1000 commits with equal ease,
+which in turn means the workflow scales much better to a large number
+of contributors (and contributions). Merges are also easier to
+understand because a merge commit is a "promise" that all changes from
+all its parents are now included.
+
+There is a tradeoff of course: merges require a more careful branch
+management. The following subsections discuss the important points.
+
+
+Graduation
+~~~~~~~~~~
+
+As a given feature goes from experimental to stable, it also
+"graduates" between the corresponding branches of the software.
+`git.git` uses the following 'integration branches':
+
+* 'maint' tracks the commits that should go into the next "maintenance
+ release", i.e., update of the last released stable version;
+
+* 'master' tracks the commits that should go into the next release;
+
+* 'next' is intended as a testing branch for topics being tested for
+ stability for master.
+
+There is a fourth official branch that is used slightly differently:
+
+* 'pu' (proposed updates) is an integration branch for things that are
+ not quite ready for inclusion yet (see "Integration Branches"
+ below).
+
+Each of the four branches is usually a direct descendant of the one
+above it.
+
+Conceptually, the feature enters at an unstable branch (usually 'next'
+or 'pu'), and "graduates" to 'master' for the next release once it is
+considered stable enough.
+
+
+Merging upwards
+~~~~~~~~~~~~~~~
+
+The "downwards graduation" discussed above cannot be done by actually
+merging downwards, however, since that would merge 'all' changes on
+the unstable branch into the stable one. Hence the following:
+
+.Merge upwards
+[caption="Rule: "]
+=====================================
+Always commit your fixes to the oldest supported branch that require
+them. Then (periodically) merge the integration branches upwards into each
+other.
+=====================================
+
+This gives a very controlled flow of fixes. If you notice that you
+have applied a fix to e.g. 'master' that is also required in 'maint',
+you will need to cherry-pick it (using linkgit:git-cherry-pick[1])
+downwards. This will happen a few times and is nothing to worry about
+unless you do it very frequently.
+
+
+Topic branches
+~~~~~~~~~~~~~~
+
+Any nontrivial feature will require several patches to implement, and
+may get extra bugfixes or improvements during its lifetime.
+
+Committing everything directly on the integration branches leads to many
+problems: Bad commits cannot be undone, so they must be reverted one
+by one, which creates confusing histories and further error potential
+when you forget to revert part of a group of changes. Working in
+parallel mixes up the changes, creating further confusion.
+
+Use of "topic branches" solves these problems. The name is pretty
+self explanatory, with a caveat that comes from the "merge upwards"
+rule above:
+
+.Topic branches
+[caption="Rule: "]
+=====================================
+Make a side branch for every topic (feature, bugfix, ...). Fork it off
+at the oldest integration branch that you will eventually want to merge it
+into.
+=====================================
+
+Many things can then be done very naturally:
+
+* To get the feature/bugfix into an integration branch, simply merge
+ it. If the topic has evolved further in the meantime, merge again.
+ (Note that you do not necessarily have to merge it to the oldest
+ integration branch first. For example, you can first merge a bugfix
+ to 'next', give it some testing time, and merge to 'maint' when you
+ know it is stable.)
+
+* If you find you need new features from the branch 'other' to continue
+ working on your topic, merge 'other' to 'topic'. (However, do not
+ do this "just habitually", see below.)
+
+* If you find you forked off the wrong branch and want to move it
+ "back in time", use linkgit:git-rebase[1].
+
+Note that the last point clashes with the other two: a topic that has
+been merged elsewhere should not be rebased. See the section on
+RECOVERING FROM UPSTREAM REBASE in linkgit:git-rebase[1].
+
+We should point out that "habitually" (regularly for no real reason)
+merging an integration branch into your topics -- and by extension,
+merging anything upstream into anything downstream on a regular basis
+-- is frowned upon:
+
+.Merge to downstream only at well-defined points
+[caption="Rule: "]
+=====================================
+Do not merge to downstream except with a good reason: upstream API
+changes affect your branch; your branch no longer merges to upstream
+cleanly; etc.
+=====================================
+
+Otherwise, the topic that was merged to suddenly contains more than a
+single (well-separated) change. The many resulting small merges will
+greatly clutter up history. Anyone who later investigates the history
+of a file will have to find out whether that merge affected the topic
+in development. An upstream might even inadvertently be merged into a
+"more stable" branch. And so on.
+
+
+Throw-away integration
+~~~~~~~~~~~~~~~~~~~~~~
+
+If you followed the last paragraph, you will now have many small topic
+branches, and occasionally wonder how they interact. Perhaps the
+result of merging them does not even work? But on the other hand, we
+want to avoid merging them anywhere "stable" because such merges
+cannot easily be undone.
+
+The solution, of course, is to make a merge that we can undo: merge
+into a throw-away branch.
+
+.Throw-away integration branches
+[caption="Rule: "]
+=====================================
+To test the interaction of several topics, merge them into a
+throw-away branch. You must never base any work on such a branch!
+=====================================
+
+If you make it (very) clear that this branch is going to be deleted
+right after the testing, you can even publish this branch, for example
+to give the testers a chance to work with it, or other developers a
+chance to see if their in-progress work will be compatible. `git.git`
+has such an official throw-away integration branch called 'pu'.
+
+
+DISTRIBUTED WORKFLOWS
+---------------------
+
+After the last section, you should know how to manage topics. In
+general, you will not be the only person working on the project, so
+you will have to share your work.
+
+Roughly speaking, there are two important workflows: merge and patch.
+The important difference is that the merge workflow can propagate full
+history, including merges, while patches cannot. Both workflows can
+be used in parallel: in `git.git`, only subsystem maintainers use
+the merge workflow, while everyone else sends patches.
+
+Note that the maintainer(s) may impose restrictions, such as
+"Signed-off-by" requirements, that all commits/patches submitted for
+inclusion must adhere to. Consult your project's documentation for
+more information.
+
+
+Merge workflow
+~~~~~~~~~~~~~~
+
+The merge workflow works by copying branches between upstream and
+downstream. Upstream can merge contributions into the official
+history; downstream base their work on the official history.
+
+There are three main tools that can be used for this:
+
+* linkgit:git-push[1] copies your branches to a remote repository,
+ usually to one that can be read by all involved parties;
+
+* linkgit:git-fetch[1] that copies remote branches to your repository;
+ and
+
+* linkgit:git-pull[1] that does fetch and merge in one go.
+
+Note the last point. Do 'not' use 'git-pull' unless you actually want
+to merge the remote branch.
+
+Getting changes out is easy:
+
+.Push/pull: Publishing branches/topics
+[caption="Recipe: "]
+=====================================
+`git push <remote> <branch>` and tell everyone where they can fetch
+from.
+=====================================
+
+You will still have to tell people by other means, such as mail. (Git
+provides the linkgit:git-request-pull[1] to send preformatted pull
+requests to upstream maintainers to simplify this task.)
+
+If you just want to get the newest copies of the integration branches,
+staying up to date is easy too:
+
+.Push/pull: Staying up to date
+[caption="Recipe: "]
+=====================================
+Use `git fetch <remote>` or `git remote update` to stay up to date.
+=====================================
+
+Then simply fork your topic branches from the stable remotes as
+explained earlier.
+
+If you are a maintainer and would like to merge other people's topic
+branches to the integration branches, they will typically send a
+request to do so by mail. Such a request looks like
+
+-------------------------------------
+Please pull from
+ <url> <branch>
+-------------------------------------
+
+In that case, 'git-pull' can do the fetch and merge in one go, as
+follows.
+
+.Push/pull: Merging remote topics
+[caption="Recipe: "]
+=====================================
+`git pull <url> <branch>`
+=====================================
+
+Occasionally, the maintainer may get merge conflicts when he tries to
+pull changes from downstream. In this case, he can ask downstream to
+do the merge and resolve the conflicts themselves (perhaps they will
+know better how to resolve them). It is one of the rare cases where
+downstream 'should' merge from upstream.
+
+
+Patch workflow
+~~~~~~~~~~~~~~
+
+If you are a contributor that sends changes upstream in the form of
+emails, you should use topic branches as usual (see above). Then use
+linkgit:git-format-patch[1] to generate the corresponding emails
+(highly recommended over manually formatting them because it makes the
+maintainer's life easier).
+
+.format-patch/am: Publishing branches/topics
+[caption="Recipe: "]
+=====================================
+* `git format-patch -M upstream..topic` to turn them into preformatted
+ patch files
+* `git send-email --to=<recipient> <patches>`
+=====================================
+
+See the linkgit:git-format-patch[1] and linkgit:git-send-email[1]
+manpages for further usage notes.
+
+If the maintainer tells you that your patch no longer applies to the
+current upstream, you will have to rebase your topic (you cannot use a
+merge because you cannot format-patch merges):
+
+.format-patch/am: Keeping topics up to date
+[caption="Recipe: "]
+=====================================
+`git pull --rebase <url> <branch>`
+=====================================
+
+You can then fix the conflicts during the rebase. Presumably you have
+not published your topic other than by mail, so rebasing it is not a
+problem.
+
+If you receive such a patch series (as maintainer, or perhaps as a
+reader of the mailing list it was sent to), save the mails to files,
+create a new topic branch and use 'git-am' to import the commits:
+
+.format-patch/am: Importing patches
+[caption="Recipe: "]
+=====================================
+`git am < patch`
+=====================================
+
+One feature worth pointing out is the three-way merge, which can help
+if you get conflicts: `git am -3` will use index information contained
+in patches to figure out the merge base. See linkgit:git-am[1] for
+other options.

+Alan <alan@clueserver.org> said:
+
+ I have a master branch. We have a branch off of that that some
+ developers are doing work on. They claim it is ready. We merge it
+ into the master branch. It breaks something so we revert the merge.
+ They make changes to the code. they get it to a point where they say
+ it is ok and we merge again.
+
+ When examined, we find that code changes made before the revert are
+ not in the master branch, but code changes after are in the master
+ branch.
+
+and asked for help recovering from this situation.
+
+The history immediately after the "revert of the merge" would look like
+this:
+
+ ---o---o---o---M---x---x---W
+ /
+ ---A---B
+
+where A and B are on the side development that was not so good, M is the
+merge that brings these premature changes into the mainline, x are changes
+unrelated to what the side branch did and already made on the mainline,
+and W is the "revert of the merge M" (doesn't W look M upside down?).
+IOW, "diff W^..W" is similar to "diff -R M^..M".
+
+Such a "revert" of a merge can be made with:
+
+ $ git revert -m 1 M
+
+After the developers of the side branch fix their mistakes, the history
+may look like this:
+
+ ---o---o---o---M---x---x---W---x
+ /
+ ---A---B-------------------C---D
+
+where C and D are to fix what was broken in A and B, and you may already
+have some other changes on the mainline after W.
+
+If you merge the updated side branch (with D at its tip), none of the
+changes made in A nor B will be in the result, because they were reverted
+by W. That is what Alan saw.
+
+Linus explains the situation:
+
+ Reverting a regular commit just effectively undoes what that commit
+ did, and is fairly straightforward. But reverting a merge commit also
+ undoes the _data_ that the commit changed, but it does absolutely
+ nothing to the effects on _history_ that the merge had.
+
+ So the merge will still exist, and it will still be seen as joining
+ the two branches together, and future merges will see that merge as
+ the last shared state - and the revert that reverted the merge brought
+ in will not affect that at all.
+
+ So a "revert" undoes the data changes, but it's very much _not_ an
+ "undo" in the sense that it doesn't undo the effects of a commit on
+ the repository history.
+
+ So if you think of "revert" as "undo", then you're going to always
+ miss this part of reverts. Yes, it undoes the data, but no, it doesn't
+ undo history.
+
+In such a situation, you would want to first revert the previous revert,
+which would make the history look like this:
+
+ ---o---o---o---M---x---x---W---x---Y
+ /
+ ---A---B-------------------C---D
+
+where Y is the revert of W. Such a "revert of the revert" can be done
+with:
+
+ $ git revert W
+
+This history would (ignoring possible conflicts between what W and W..Y
+changed) be equivalent to not having W nor Y at all in the history:
+
+ ---o---o---o---M---x---x-------x----
+ /
+ ---A---B-------------------C---D
+
+and merging the side branch again will not have conflict arising from an
+earlier revert and revert of the revert.
+
+ ---o---o---o---M---x---x-------x-------*
+ / /
+ ---A---B-------------------C---D
+
+Of course the changes made in C and D still can conflict with what was
+done by any of the x, but that is just a normal merge conflict.
+
+On the other hand, if the developers of the side branch discarded their
+faulty A and B, and redone the changes on top of the updated mainline
+after the revert, the history would have looked like this:
+
+ ---o---o---o---M---x---x---W---x---x
+ / \
+ ---A---B A'--B'--C'
+
+If you reverted the revert in such a case as in the previous example:
+
+ ---o---o---o---M---x---x---W---x---x---Y---*
+ / \ /
+ ---A---B A'--B'--C'
+
+where Y is the revert of W, A' and B' are rerolled A and B, and there may
+also be a further fix-up C' on the side branch. "diff Y^..Y" is similar
+to "diff -R W^..W" (which in turn means it is similar to "diff M^..M"),
+and "diff A'^..C'" by definition would be similar but different from that,
+because it is a rerolled series of the earlier change. There will be a
+lot of overlapping changes that result in conflicts. So do not do "revert
+of revert" blindly without thinking..
+
+ ---o---o---o---M---x---x---W---x---x
+ / \
+ ---A---B A'--B'--C'
+
+In the history with rebased side branch, W (and M) are behind the merge
+base of the updated branch and the tip of the mainline, and they should
+merge without the past faulty merge and its revert getting in the way.
+
+To recap, these are two very different scenarios, and they want two very
+different resolution strategies:
+
+ - If the faulty side branch was fixed by adding corrections on top, then
+ doing a revert of the previous revert would be the right thing to do.
+
+ - If the faulty side branch whose effects were discarded by an earlier
+ revert of a merge was rebuilt from scratch (i.e. rebasing and fixing,
+ as you seem to have interpreted), then re-merging the result without
+ doing anything else fancy would be the right thing to do.
+
+However, there are things to keep in mind when reverting a merge (and
+reverting such a revert).
+
+For example, think about what reverting a merge (and then reverting the
+revert) does to bisectability. Ignore the fact that the revert of a revert
+is undoing it - just think of it as a "single commit that does a lot".
+Because that is what it does.
+
+When you have a problem you are chasing down, and you hit a "revert this
+merge", what you're hitting is essentially a single commit that contains
+all the changes (but obviously in reverse) of all the commits that got
+merged. So it's debugging hell, because now you don't have lots of small
+changes that you can try to pinpoint which _part_ of it changes.
+
+But does it all work? Sure it does. You can revert a merge, and from a
+purely technical angle, git did it very naturally and had no real
+troubles. It just considered it a change from "state before merge" to
+"state after merge", and that was it. Nothing complicated, nothing odd,
+nothing really dangerous. Git will do it without even thinking about it.
+
+So from a technical angle, there's nothing wrong with reverting a merge,
+but from a workflow angle it's something that you generally should try to
+avoid.
+
+If at all possible, for example, if you find a problem that got merged
+into the main tree, rather than revert the merge, try _really_ hard to
+bisect the problem down into the branch you merged, and just fix it, or
+try to revert the individual commit that caused it.
+
+Yes, it's more complex, and no, it's not always going to work (sometimes
+the answer is: "oops, I really shouldn't have merged it, because it wasn't
+ready yet, and I really need to undo _all_ of the merge"). So then you
+really should revert the merge, but when you want to re-do the merge, you
+now need to do it by reverting the revert.

+If the file `.mailmap` exists at the toplevel of the repository, or at

+is used to map author and committer names and email addresses to

+
+In the simple form, each line in the file consists of the canonical

+commit (enclosed by '<' and '>') to map to the name. For example:
+--
+ Proper Name <commit@email.xx>

+
+------------
+Jane Doe <jane@desktop.(none)>
+Joe R. Developer <joe@example.com>
+------------
+
+Note how there is no need for an entry for <jane@laptop.(none)>, because the

History Simplification
~~~~~~~~~~~~~~~~~~~~~~
-When optional paths are given, 'git rev-list' simplifies commits with
-various strategies, according to the options you have selected.
+Sometimes you are only interested in parts of the history, for example the
+commits modifying a particular <path>. But there are two parts of
+'History Simplification', one part is selecting the commits and the other
+is how to do it, as there are various strategies to simplify the history.
+
+The following options select the commits to be shown:

+<paths>::

+ Commits modifying the given <paths> are selected.
+
+--simplify-by-decoration::

+Default mode::

+ Simplifies the history to the simplest history explaining the
+ final state of the tree. Simplest because it prunes some side
+ branches if the end result is the same (i.e. merging branches
+ with the same content)

+ As the default mode but does not prune some history.
+
+--dense::

+
+--simplify-merges::
+
+ Additional option to '--full-history' to remove some needless
+ merges from the resulting history, as there are no selected

+
+ First, build a history graph in the same way that

+Then simplify each commit `C` to its replacement `C'` in the final

++
+--
+* Set `C'` to `C`.
++
+* Replace each parent `P` of `C'` with its simplification `P'`. In
+ the process, drop parents that are ancestors of other parents, and
+ remove duplicates.

+* If after this parent rewriting, `C'` is a root or merge commit (has
+ zero or >1 parents), a boundary commit, or !TREESAME, it remains.
+ Otherwise, it is replaced with its only parent.
