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.

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 $PATH. + + * An element on GIT_CEILING_DIRECTORIES could be a "logical" pathname + that uses a symbolic link to point at somewhere else (e.g. /home/me + that points at /net/host/export/home/me, and the latter directory + is automounted). Earlier when Git saw such a pathname e.g. /home/me + on this environment variable, the "ceiling" mechanism did not take + effect. With this release (the fix has also been merged to the + v1.8.1.x maintenance series), elements on GIT_CEILING_DIRECTORIES + are by default checked for such aliasing coming from symbolic + links. As this needs to actually resolve symbolic links for each + element on the GIT_CEILING_DIRECTORIES, you can disable this + mechanism for some elements by listing them after an empty element + on the GIT_CEILING_DIRECTORIES. e.g. Setting /home/me::/home/him to + GIT_CEILING_DIRECTORIES makes Git resolve symbolic links in + /home/me when checking if the current directory is under /home/me, + but does not do so for /home/him. + (merge 7ec30aa mh/maint-ceil-absolute later to maint). diff --git a/Documentation/RelNotes/1.8.3.txt b/Documentation/RelNotes/1.8.3.txt new file mode 100644 index 0000000000..b027992d82 --- /dev/null +++ b/Documentation/RelNotes/1.8.3.txt @@ -0,0 +1,207 @@ +Git v1.8.3 Release Notes +======================== + +Backward compatibility notes (for Git 2.0) +------------------------------------------ + +When "git push [$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 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 v1.8.2 +-------------------- + +UI, Workflows & Features + + * When the interactive access to git-shell is not enabled, it issues + a message meant to help the system admininstrator to enable it. + An explicit way to help the end users who connect to the service by + issuing custom messages to refuse such an access has been added. + + * "git status" suggests users to look into using--untracked=no option + when it takes too long. + + * "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. + + * "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 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 other backend + expects. + + +Performance, Internal Implementation, etc. + + * Updates for building under msvc. + + * A few codepaths knew how much data they need to put in the + hashtables they use upfront, but still started from a small table + repeatedly growing and rehashing. + + * 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. + + +Also contains minor 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). + + * Annotated tags outside refs/tags/ hierarchy were not advertised + correctly to the ls-remote and fetch with recent version of Git. + (merge c29c46f jk/fully-peeled-packed-ref later to maint). + + * Recent optimization broke shallow clones. + (merge f59de5d jk/peel-ref later to maint). + + * "git cmd -- ':(top'" was not diagnosed as an invalid syntax, and + instead the parser kept reading beyond the end of the string. + (merge f612a67 lf/setup-prefix-pathspec later to maint). + + * "git tag -f <tag>" always said "Updated tag '<tag>'" even when + creating a new tag (i.e. not overwriting nor updating). + (merge 3ae851e ph/tag-force-no-warn-on-creation later to maint). + + * "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" reports a failure when asked to create an archive out + of an empty tree.
