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).
