Careless users who forget to sufficiently quote $args +get their argument split at $IFS whitespaces by the shell, and got +unexpected results due to this. Starting from this release, the +command line is passed directly to the shell, if it has an argument. + +Read-only support for experimental loose-object format, in which users +could optionally choose to write their loose objects for a short +while between v1.4.3 and v1.5.3 era, has been dropped. + +The meanings of the "--tags" option to "git fetch" has changed; the +command fetches tags _in addition to_ what is fetched by the same +command line without the option. + +The way "git push $there $what" interprets the $what part given on the +command line, when it does not have a colon that explicitly tells us +what ref at the $there repository is to be updated, has been enhanced. + +A handful of ancient commands that have long been deprecated are +finally gone (repo-config, tar-tree, lost-found, and peek-remote). + + +Backward compatibility notes (for Git 2.0.0) +-------------------------------------------- + +When "git push [$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, which pushes: + + - only the current branch to the branch with the same name, and only + when the current branch is set to integrate with that remote + branch, if you are pushing to the same remote as you fetch from; or + + - only the current branch to the branch with the same name, if you + are pushing to a remote that is not where you usually fetch from. + +Use the 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 the variable 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") is run inside a subdirectory and +does not specify which paths to add on the command line, it +will operate on the entire tree in Git 2.0 for consistency +with "git commit -a" and other commands. There will be no +mechanism to make plain "git add -u" behave like "git add -u .". +Current users of "git add -u" (without a pathspec) should start +training their fingers to explicitly say "git add -u ." +before Git 2.0 comes. A warning is issued when these commands are +run without a pathspec and when you have local changes outside the +current directory, because the behaviour in Git 2.0 will be different +from today's version in such a situation. + +In Git 2.0, "git add <path>" will behave as "git add -A <path>", so +that "git add dir/" will notice paths you removed from the directory +and record the removal. Versions before Git 2.0, including this +release, will keep ignoring removals, but the users who rely on this +behaviour are encouraged to start using "git add --ignore-removal <path>" +now before 2.0 is released. + +The default prefix for "git svn" will change in Git 2.0. For a long +time, "git svn" created its remote-tracking branches directly under +refs/remotes, but it will place them under refs/remotes/origin/ unless +it is told otherwise with its --prefix option. + + +Updates since v1.8.5 +-------------------- + +Foreign interfaces, subsystems and ports. + + * The HTTP transport, when talking GSS-Negotiate, uses "100 + Continue" response to avoid having to rewind and resend a large + payload, which may not be always doable. + + * Various bugfixes to remote-bzr and remote-hg (in contrib/). + + * The build procedure is aware of MirBSD now. + + * Various "git p4", "git svn" and "gitk" updates. + + +UI, Workflows & Features + + * Fetching from a shallowly-cloned repository used to be forbidden, + primarily because the codepaths involved were not carefully vetted + and we did not bother supporting such usage. This release attempts + to allow object transfer out of a shallowly-cloned repository in a + more controlled way (i.e. the receiver becomes a shallow repository + with a truncated history). + + * Just like we give a reasonable default for "less" via the LESS + environment variable, we now specify a reasonable default for "lv" + via the "LV" environment variable when spawning the pager. + + * Two-level configuration variable names in "branch.*" and "remote.*" + hierarchies, whose variables are predominantly three-level, were + not completed by hitting a <TAB> in bash and zsh completions. + + * Fetching a 'frotz' branch with "git fetch", while a 'frotz/nitfol' + remote-tracking branch from an earlier fetch was still there, would + error out, primarily because the command was not told that it is + allowed to lose any information on our side. "git fetch --prune" + now can be used to remove 'frotz/nitfol' to make room for fetching and + storing the 'frotz' remote-tracking branch. + + * "diff.orderfile=<file>" configuration variable can be used to + pretend as if the "-O<file>" option were given from the command + line of "git diff", etc. + + * The negative pathspec syntax allows "git log -- . ':!dir'" to tell + us "I am interested in everything but 'dir' directory". + + * "git difftool" shows how many different paths there are in total, + and how many of them have been shown so far, to indicate progress. + + * "git push origin master" used to push our 'master' branch to update + the 'master' branch at the 'origin' repository. This has been + enhanced to use the same ref mapping "git push origin" would use to + determine what ref at the 'origin' to be updated with our 'master'. + For example, with this configuration + + [remote "origin"] + push = refs/heads/*:refs/review/* + + that would cause "git push origin" to push out our local branches + to corresponding refs under refs/review/ hierarchy at 'origin', + "git push origin master" would update 'refs/review/master' over + there. Alternatively, if push.default is set to 'upstream' and our + 'master' is set to integrate with 'topic' from the 'origin' branch, + running "git push origin" while on our 'master' would update their + 'topic' branch, and running "git push origin master" while on any + of our branches does the same. + + * "gitweb" learned to treat ref hierarchies other than refs/heads as + if they are additional branch namespaces (e.g. refs/changes/ in + Gerrit). + + * "git for-each-ref --format=..." learned a few formatting directives; + e.g. "%(color:red)%(HEAD)%(color:reset) %(refname:short) %(subject)". + + * The command string given to "git submodule foreach" is passed + directly to the shell, without being eval'ed. This is a backward + incompatible change that may break existing users. + + * "git log" and friends learned the "--exclude=<glob>" option, to + allow people to say "list history of all branches except those that + match this pattern" with "git log --exclude='*/*' --branches". + + * "git rev-parse --parseopt" learned a new "--stuck-long" option to + help scripts parse options with an optional parameter. + + * The "--tags" option to "git fetch" no longer tells the command to + fetch _only_ the tags. It instead fetches tags _in addition to_ + what are fetched by the same command line without the option. + + +Performance, Internal Implementation, etc. + + * When parsing a 40-hex string into the object name, the string is + checked to see if it can be interpreted as a ref so that a warning + can be given for ambiguity. The code kicked in even when the + core.warnambiguousrefs is set to false to squelch this warning, in + which case the cycles spent to look at the ref namespace were an + expensive no-op, as the result was discarded without being used. + + * The naming convention of the packfiles has been updated; it used to + be based on the enumeration of names of the objects that are + contained in the pack, but now it also depends on how the packed + result is represented---packing the same set of objects using + different settings (or delta order) would produce a pack with + different name. + + * "git diff --no-index" mode used to unnecessarily attempt to read + the index when there is one. + + * The deprecated parse-options macro OPT_BOOLEAN has been removed; + use OPT_BOOL or OPT_COUNTUP in new code. + + * A few duplicate implementations of prefix/suffix string comparison + functions have been unified to starts_with() and ends_with(). + + * The new PERLLIB_EXTRA makefile variable can be used to specify + additional directories Perl modules (e.g. the ones necessary to run + git-svn) are installed on the platform when building. + + * "git merge-base" learned the "--fork-point" mode, that implements + the same logic used in "git pull --rebase" to find a suitable fork + point out of the reflog entries for the remote-tracking branch the + work has been based on. "git rebase" has the same logic that can be + triggered with the "--fork-point" option. + + * A third-party "receive-pack" (the responder to "git push") can + advertise the "no-thin" capability to tell "git push" not to use + the thin-pack optimization. Our receive-pack has always been + capable of accepting and fattening a thin-pack, and will continue + not to ask "git push" to use a non-thin pack. + + +Also contains various documentation updates and code clean-ups. + + +Fixes since v1.8.5 +------------------ + +Unless otherwise noted, all the fixes since v1.8.5 in the maintenance +track are contained in this release (see the maintenance releases' notes +for details). + + * The pathspec matching code, while comparing two trees (e.g. "git + diff A B -- path1 path2") was too aggressive and failed to match + some paths when multiple pathspecs were involved. + + * "git repack --max-pack-size=8g" stopped being parsed correctly when + the command was reimplemented in C. + + * An earlier update in v1.8.4.x to "git rev-list --objects" with + negative ref had a performance regression. + (merge 200abe7 jk/mark-edges-uninteresting later to maint). + + * A recent update to "git send-email" broke platforms where + /etc/ssl/certs/ directory exists but cannot be used as SSL_ca_path + (e.g. Fedora rawhide). + + * A handful of bugs around interpreting $branch@{upstream} notation + and its lookalike, when $branch part has interesting characters, + e.g. "@", and ":", have been fixed. + + * "git clone" would fail to clone from a repository that has a ref + directly under "refs/", e.g. "refs/stash", because different + validation paths do different things on such a refname.

When you pushed out your 'master' branch to your public + repository as 'for-linus', use the new "master:for-linus" syntax to + denote the branch to be pulled. + + * "git grep" learned to behave in a way similar to native grep when + "-h" (no header) and "-c" (count) options are given. + + * "git push" via transport-helper interface (e.g. remote-hg) has + been updated to allow ref deletion in a way similar to the natively + supported transports. + + * The "simple" mode is the default for "git push". + + * "git add -u" and "git add -A", when run without any pathspec, is a + tree-wide operation even when run inside a subdirectory of a + working tree. + + * "git add <path> is the same as "git add -A <path>" now. + + * "core.statinfo" configuration variable, which is a + never-advertised synonym to "core.checkstat", has been removed. + + * The "-q" option to "git diff-files", which does *NOT* mean + "quiet", has been removed (it told Git to ignore deletion, which + you can do with "git diff-files --diff-filter=d"). + + * Server operators can loosen the "tips of refs only" restriction for + the remote archive service with the uploadarchive.allowUnreachable + configuration option. + + * The progress indicators from various time-consuming commands have + been marked for i18n/l10n. + + * "git notes -C <blob>" diagnoses an attempt to use an object that + is not a blob as an error. + + * "git config" learned to read from the standard input when "-" is + given as the value to its "--file" parameter (attempting an + operation to update the configuration in the standard input of + course is rejected). + + * Trailing whitespaces in .gitignore files, unless they are quoted + for fnmatch(3), e.g. "path\ ", are warned and ignored. Strictly + speaking, this is a backward incompatible change, but very unlikely + to bite any sane user and adjusting should be obvious and easy. + + * Many commands that create commits, e.g. "pull", "rebase", + learned to take the --gpg-sign option on the command line. + + * "git commit" can be told to always GPG sign the resulting commit + by setting "commit.gpgsign" configuration variable to true (the + command line option --no-gpg-sign should override it). + + * "git pull" can be told to only accept fast-forward by setting the + new "pull.ff" configuration. + + * "git reset" learned "-N" option, which does not reset the index + fully for paths the index knows about but the tree-ish the command + resets to does not (these paths are kept as intend-to-add entries). + + +Performance, Internal Implementation, etc. + + * The compilation options to port to AIX and to MSVC have been + updated. + + * We started using wildmatch() in place of fnmatch(3) a few releases + ago; complete the process and stop using fnmatch(3). + + * Uses of curl's "multi" interface and "easy" interface do not mix + well when we attempt to reuse outgoing connections. Teach the RPC + over http code, used in the smart HTTP transport, not to use the + "easy" interface. + + * The bitmap-index feature from JGit has been ported, which should + significantly improve performance when serving objects form a + repository that uses it. + + * The way "git log --cc" shows a combined diff against multiple + parents have been optimized. + + * The prefixcmp() and suffixcmp() functions are gone. Use + starts_with() and ends_with(), and also consider if skip_prefix() + suits your needs better when using the former. + + +Also contains various documentation updates and code clean-ups. Many +of them came from flurry of activities as GSoC candidate microproject +exercises. + + +Fixes since v1.9 series +----------------------- + +Unless otherwise noted, all the fixes since v1.9 in the maintenance +track are contained in this release (see the maintenance releases' +notes for details). + + * The remote-helepr interface to fast-import/fast-export via the + transport-helper has been tightened to avoid leaving the import + marks file from a failed/crashed run, as such a file that is out of + sync with the reality confuses a later invocation of itself. + + * "git rebase" used a POSIX shell construct FreeBSD /bin/sh does not + work well with. + (merge 8cd6596 km/avoid-non-function-return-in-rebase later to maint). + + * zsh prompt (in contrib/) leaked unnecessary error messages. + + * bash completion (in contrib/) did not complete the refs and remotes + correctly given "git pu<TAB>" when "pu" is aliased to "push". + + * Some more Unicode codepoints defined in Unicode 6.3 as having zero + width have been taught to our display column counting logic. + (merge d813ab9 tb/unicode-6.3-zero-width later to maint). + + * Some tests used shell constructs that did not work well on FreeBSD + (merge ff7a1c6 km/avoid-bs-in-shell-glob later to maint). + (merge 00764ca km/avoid-cp-a later to maint). + + * "git update-ref --stdin" did not fail a request to create a ref + when the ref already existed. + (merge b9d56b5 mh/update-ref-batch-create-fix later to maint). + + * "git diff --no-index -Mq a b" fell into an infinite loop. + (merge ad1c3fb jc/fix-diff-no-index-diff-opt-parse later to maint). + + * "git fetch --prune", when the right-hand-side of multiple fetch + refspecs overlap (e.g. storing "refs/heads/*" to + "refs/remotes/origin/*", while storing "refs/frotz/*" to + "refs/remotes/origin/fr/*"), aggressively thought that lack of + "refs/heads/fr/otz" on the origin site meant we should remove + "refs/remotes/origin/fr/otz" from us, without checking their + "refs/frotz/otz" first. + + Note that such a configuration is inherently unsafe (think what + should happen when "refs/heads/fr/otz" does appear on the origin + site), but that is not a reason not to be extra careful. + (merge e6f6371 cn/fetch-prune-overlapping-destination later to maint). + + * "git status --porcelain --branch" showed its output with labels + "ahead/behind/gone" translated to the user's locale. + (merge 7a76c28 mm/status-porcelain-format-i18n-fix later to maint). + + * A stray environment variable $prefix could have leaked into and + affected the behaviour of the "subtree" script (in contrib/). + + * When it is not necessary to edit a commit log message (e.g. "git + commit -m" is given a message without specifying "-e"), we used to + disable the spawning of the editor by overriding GIT_EDITOR, but + this means all the uses of the editor, other than to edit the + commit log message, are also affected. + (merge b549be0 bp/commit-p-editor later to maint). + + * "git mv" that moves a submodule forgot to adjust the array that + uses to keep track of which submodules were to be moved to update + its configuration. + (merge fb8a4e8 jk/mv-submodules-fix later to maint). + + * Length limit for the pathname used when removing a path in a deep + subdirectory has been removed to avoid buffer overflows. + (merge 2f29e0c mh/remove-subtree-long-pathname-fix later to maint). + + * The test helper lib-terminal always run an actual test_expect_* + when included, which screwed up with the use of skil-all that may + have to be done later. + (merge 7e27173 jk/lib-terminal-lazy later to maint). + + * "git index-pack" used a wrong variable to name the keep-file in an + error message when the file cannot be written or closed. + (merge de983a0 nd/index-pack-error-message later to maint). + + * "rebase -i" produced a broken insn sheet when the title of a commit + happened to contain '\n' (or ended with '\c') due to a careless use + of 'echo'. + (merge cb1aefd us/printf-not-echo later to maint). + + * There were a few instances of 'git-foo' remaining in the + documentation that should have been spelled 'git foo'. + (merge 3c3e6f5 rr/doc-merge-strategies later to maint). + + * Serving objects from a shallow repository needs to write a + new file to hold the temporary shallow boundaries but it was not + cleaned when we exit due to die() or a signal. + (merge 7839632 jk/shallow-update-fix later to maint). + + * When "git stash pop" stops after failing to apply the stash + (e.g. due to conflicting changes), the stash is not dropped. State + that explicitly in the output to let the users know. + (merge 2d4c993 jc/stash-pop-not-popped later to maint). + + * The labels in "git status" output that describe the nature of + conflicts (e.g. "both deleted") were limited to 20 bytes, which was + too short for some l10n (e.g. fr). + (merge c7cb333 jn/wt-status later to maint). + + * "git clean -d pathspec" did not use the given pathspec correctly + and ended up cleaning too much. + (merge 1f2e108 jk/clean-d-pathspec later to maint). + + * "git difftool" misbehaved when the repository is bound to the + working tree with the ".git file" mechanism, where a textual file + ".git" tells us where it is. + (merge fcfec8b da/difftool-git-files later to maint). + + * "git push" did not pay attention to branch.*.pushremote if it is + defined earlier than remote.pushdefault; the order of these two + variables in the configuration file should not matter, but it did + by mistake. + (merge 98b406f jk/remote-pushremote-config-reading later to maint). + + * Codepaths that parse timestamps in commit objects have been + tightened. + (merge f80d1f9 jk/commit-dates-parsing-fix later to maint). + + * "git diff --external-diff" incorrectly fed the submodule directory + in the working tree to the external diff driver when it knew it is + the same as one of the versions being compared. + (merge aba4727 tr/diff-submodule-no-reuse-worktree later to maint). + + * "git reset" needs to refresh the index when working in a working + tree (it can also be used to match the index to the HEAD in an + otherwise bare repository), but it failed to set up the working + tree properly, causing GIT_WORK_TREE to be ignored. + (merge b7756d4 nd/reset-setup-worktree later to maint). + + * "git check-attr" when working on a repository with a working tree + did not work well when the working tree was specified via the + --work-tree (and obviously with --git-dir) option. + (merge cdbf623 jc/check-attr-honor-working-tree later to maint). + + * "merge-recursive" was broken in 1.7.7 era and stopped working in + an empty (temporary) working tree, when there are renames + involved. This has been corrected. + (merge 6e2068a bk/refresh-missing-ok-in-merge-recursive later to maint.) + + * "git rev-parse" was loose in rejecting command line arguments + that do not make sense, e.g. "--default" without the required + value for that option. + (merge a43219f ds/rev-parse-required-args later to maint.) + + * include.path variable (or any variable that expects a path that + can use ~username expansion) in the configuration file is not a + boolean, but the code failed to check it. + (merge 67beb60 jk/config-path-include-fix later to maint.) + + * Commands that take pathspecs on the command line misbehaved when + the pathspec is given as an absolute pathname (which is a + practice not particularly encouraged) that points at a symbolic + link in the working tree. + (merge later 655ee9e mw/symlinks to maint.) + + * "git diff --quiet -- pathspec1 pathspec2" sometimes did not return + correct status value. + (merge f34b205 nd/diff-quiet-stat-dirty later to maint.) + + * Attempting to deepen a shallow repository by fetching over smart + HTTP transport failed in the protocol exchange, when no-done + extension was used. The fetching side waited for the list of + shallow boundary commits after the sending end stopped talking to + it. + (merge 0232852 nd/http-fetch-shallow-fix later to maint.) + + * Allow "git cmd path/", when the 'path' is where a submodule is + bound to the top-level working tree, to match 'path', despite the + extra and unnecessary trailing slash (such a slash is often + given by command line completion). + (merge 2e70c01 nd/submodule-pathspec-ending-with-slash later to maint.) + + * Documentation and in-code comments had many instances of mistaken + use of "nor", which have been corrected. + (merge 235e8d5 jl/nor-or-nand-and later to maint). |
