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. + + * "git difftool" allows the user to write into the temporary files + being shown; if the user makes changes to the working tree at the + same time, one of the changes has to be lost in such a case, but it + tells the user what happened and refrains from overwriting the copy + in the working tree. + + * There was no good way to ask "I have a random string that came from + outside world. I want to turn it into a 40-hex object name while + making sure such an object exists". A new peeling suffix ^{object} + can be used for that purpose, together with "rev-parse --verify". + + +Performance, Internal Implementation, etc. + + * Updates for building under msvc. + + * A 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. + + * "git checkout" had repeated pathspec matches on the same paths, + which have been consolidated. Also a bug in "git checkout dir/" + that is started from an unmerged index has been fixed. + + +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). + + * Fix 1.8.1.x regression that stopped matching "dir" (without + trailing slash) to a directory "dir". + (merge efa5f82 jc/directory-attrs-regression-fix later to maint-1.8.1). + + * "git apply --whitespace=fix" was not prepared to see a line getting + longer after fixing whitespaces (e.g. tab-in-indent aka Python). + (merge 329b26e jc/apply-ws-fix-tab-in-indent later to maint-1.8.1). + + * The prompt string generator (in contrib/completion/) did not notice + when we are in a middle of a "git revert" session. + (merge 3ee4452 rr/prompt-revert-head later to maint). + + * "submodule summary --summary-limit" option did not support + "--option=value" form. + (merge 862ae6c rs/submodule-summary-limit later to maint). + + * "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. + + * Annotated tags outside refs/tags/ hierarchy were not advertised + correctly to the ls-remote and fetch with recent version of Git. + + * 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. + + * "git tag -f <tag>" always said "Updated tag '<tag>'" even when + creating a new tag (i.e. not overwriting nor updating). + + * "git p4" did not behave well when the path to the root of the P4 + client was not its real path. + (merge bbd8486 pw/p4-symlinked-root later to maint). + + * "git archive" 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. + + * 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. + + * 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. + + * 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=<pattern>" option of "git describe", when used with + "--all" to allow refs that are not annotated tags to be used as a + base of description, did not restrict the output from the command + to those that match the given pattern. + + * Clarify in the documentation "what" gets pushed to "where" when the + command line to "git push" does not say these explicitly. + + * The "--color=<when>" argument to the commands in the diff family + was described poorly. + + * The arguments given to pre-rebase hook were not documented. + + * The v4 index format was not documented. + + * The "--match=<pattern>" argument "git describe" takes uses glob + pattern but it wasn't obvious from the documentation. + + * Some sources failed to compile on systems that lack NI_MAXHOST in + their system header (e.g. z/OS). + + * Add an example use of "--env-filter" in "filter-branch" + documentation. + + * "git bundle verify" did not say "records a complete history" for a + bundle that does not have any prerequisites. + + * In the v1.8.0 era, we changed symbols that do not have to be global + to file scope static, but a few functions in graph.c were used by + CGit from sideways bypassing the entry points of the API the + in-tree users use. + + * "git update-index -h" did not do the usual "-h(elp)" thing. + + * "git index-pack" had a buffer-overflow while preparing an + informational message when the translated version of it was too + long. + + * 'git commit -m "$msg"' used to add an extra newline even when + $msg already ended with one. + + * The SSL peer verification done by "git imap-send" did not ask for + Server Name Indication (RFC 4366), failing to connect 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. + + * 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. diff --git a/Documentation/config.txt b/Documentation/config.txt index bc750d5794..f79184c0a8 100644 --- a/Documentation/config.txt +++ b/Documentation/config.txt @@ -2123,7 +2123,13 @@ uploadpack.hiderefs:: are under the hierarchies listed on the value of this variable is excluded, and is hidden from `git ls-remote`, `git fetch`, etc. An attempt to fetch a hidden ref by `git - fetch` will fail. + fetch` will fail.
