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. * In addition to the case where the user edits the log message with the "e)dit" option of "am -i", replace the "Applying: this patch" message with the final log message contents after applymsg hook munges it. * "git status" suggests users to look into using --untracked=no option when it takes too long. * "git status" shows a bit more information to "git status" during a rebase/bisect session. * "git fetch" learned to fetch a commit at the tip of an unadvertised ref by specifying a raw object name from the command line when the server side supports this feature. * "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. * "show/log" now honors gpg.program configuration just like other parts of the code that use GnuPG. * "git log" that shows the difference between the parent and the child has been optimized somewhat. 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. * Codepaths that inspect log-message-to-be and decide when to add a new Signed-off-by line in various commands have been consolidated. * The pkt-line API, implementation and its callers have been cleaned up to make them more robust. * Cygwin port has a faster-but-lying lstat(2) emulation whose incorrectness does not matter in practice except for a few codepaths, and setting permission bits to directories is a codepath that needs to use a more correct one. 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). * "index-pack --fix-thin" used uninitialize value to compute delta depths of objects it appends to the resulting pack. (merge 57165db jk/index-pack-correct-depth-fix later to maint). * "index-pack --verify-stat" used a few counters outside protection of mutex, possibly showing incorrect numbers. (merge 8f82aad nd/index-pack-threaded-fixes later to maint). * The code to keep track of what directory names are known to Git on platforms with case insensitive filesystems can get confused upon a hash collision between these pathnames and looped forever. (merge 2092678 kb/name-hash later to maint). * 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 " always said "Updated 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. It would be more intuitive to give an empty archive back in such a case. (merge bd54cf1 jk/empty-archive later to maint). * When "format-patch" quoted a non-ascii strings on the header files, it incorrectly applied rfc2047 and chopped a single character in the middle of it. (merge 6cd3c05 ks/rfc2047-one-char-at-a-time later to maint). * An aliased command spawned from a bare repository that does not say it is bare with "core.bare = yes" is treated as non-bare by mistake. (merge 2cd83d1 jk/alias-in-bare later to maint). * In "git reflog expire", REACHABLE bit was not cleared from the correct objects. * The logic used by "git diff -M --stat" to shorten the names of files before and after a rename did not work correctly when the common prefix and suffix between the two filenames overlapped. * The "--match=" option of "git describe", when used with "--all" to allow refs that are not annotated tags to be used as a base of description, did not restrict the output from the command to those that match the given pattern. (merge 46e1d6e jc/describe later to maint). * Clarify in the documentation "what" gets pushed to "where" when the command line to "git push" does not say these explicitly. * The "--color=" argument to the commands in the diff family was described poorly. * The arguments given to pre-rebase hook were not documented. * The v4 index format was not documented. * The "--match=" argument "git describe" takes uses glob pattern but it wasn't obvious from the documentation. * Some sources failed to compile on systems that lack NI_MAXHOST in their system header (e.g. z/OS). * Add an example use of "--env-filter" in "filter-branch" documentation. * "git bundle verify" did not say "records a complete history" for a bundle that does not have any prerequisites. * In the v1.8.0 era, we changed symbols that do not have to be global to file scope static, but a few functions in graph.c were used by CGit from sideways bypassing the entry points of the API the in-tree users use. * "git update-index -h" did not do the usual "-h(elp)" thing. * "git index-pack" had a buffer-overflow while preparing an informational message when the translated version of it was too long. * 'git commit -m "$msg"' used to add an extra newline even when $msg already ended with one. (merge 46fbf75 bc/commit-complete-lines-given-via-m-option later to maint). * The SSL peer verification done by "git imap-send" did not ask for Server Name Indication (RFC 4366), failing to connect SSL/TLS sites that serve multiple hostnames on a single IP. * perl/Git.pm::cat_blob slurped everything in core only to write it out to a file descriptor, which was not a very smart thing to do. * "git branch" did not bother to check nonsense command line parameters and issue errors in many cases. * Verification of signed tags were not done correctly when not in C or en/US locale. (merge 0174eea mg/gpg-interface-using-status later to maint). * Some platforms and users spell UTF-8 differently; retry with the most official "UTF-8" when the system does not understand the user-supplied encoding name that are the common alternative spellings of UTF-8. * When export-subst is used, "zip" output recorded incorrect size of the file. * "git am $maildir/" applied messages in an unexpected order; sort filenames read from the maildir/ in a way that is more likely to sort messages in the order the writing MUA meant to, by sorting numeric segment in numeric order and non-numeric segment in alphabetical order. * "git submodule update", when recursed into sub-submodules, did not acccumulate the prefix paths.
