In Git 2.0, the default is now 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. - -You can use the configuration variable "push.default" to change -this. If you are an old-timer who wants to keep using the -"matching" semantics, you can set the variable to "matching", for -example. Read the documentation for other possibilities. - -When "git add -u" and "git add -A" are run inside a subdirectory -without specifying which paths to add on the command line, they -operate on the entire tree for consistency with "git commit -a" and -other commands (these commands used to operate only on the current -subdirectory). Say "git add -u ." or "git add -A ." if you want to -limit the operation to the current directory. - -"git add <path>" is the same as "git add -A <path>" now, so that -"git add dir/" will notice paths you removed from the directory and -record the removal. In older versions of Git, "git add <path>" used -to ignore removals. You can say "git add --ignore-removal <path>" to -add only added or modified paths in <path>, if you really want to. - -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"). - -"git request-pull" lost a few "heuristics" that often led to mistakes. - -The default prefix for "git svn" has changed in Git 2.0. For a long -time, "git svn" created its remote-tracking branches directly under -refs/remotes, but it now places them under refs/remotes/origin/ unless -it is told otherwise with its "--prefix" option. - - -Updates since v1.9 series -------------------------- - -UI, Workflows & Features - - * The "multi-mail" post-receive hook (in contrib/) has been updated - to a more recent version from upstream. - - * The "remote-hg/bzr" remote-helper interfaces (used to be in - contrib/) are no more. They are now maintained separately as - third-party plug-ins in their own repositories. - - * "git gc --aggressive" learned "--depth" option and - "gc.aggressiveDepth" configuration variable to allow use of a less - insane depth than the built-in default value of 250. - - * "git log" learned the "--show-linear-break" option to show where a - single strand-of-pearls is broken in its output. - - * The "rev-parse --parseopt" mechanism used by scripted Porcelains to - parse command-line options and to give help text learned to take - the argv-help (the placeholder string for an option parameter, - e.g. "key-id" in "--gpg-sign=<key-id>"). - - * The pattern to find where the function begins in C/C++ used in - "diff" and "grep -p" has been updated to improve viewing C++ - sources. - - * "git rebase" learned to interpret a lone "-" as "@{-1}", the - branch that we were previously on. - - * "git commit --cleanup=<mode>" learned a new mode, scissors. - - * "git tag --list" output can be sorted using "version sort" with - "--sort=version:refname". - - * Discard the accumulated "heuristics" to guess from which branch the - result wants to be pulled from and make sure that what the end user - specified is not second-guessed by "git request-pull", to avoid - mistakes. 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 has been updated to - allow forced ref updates 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 as an error an attempt to use an - object that is not a blob. - - * "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 is - rejected, of course). - - * 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" and "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 the "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 variable. - - * "git reset" learned the "-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 from a - repository that uses it. - - * The way "git log --cc" shows a combined diff against multiple - parents has 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). - - * "git p4" was broken in 1.9 release to deal with changes in binary - files. - (merge 749b668 cl/p4-use-diff-tree later to maint). - - * The shell prompt script (in contrib/), when using the PROMPT_COMMAND - interface, used an unsafe construct when showing the branch name in - $PS1. - (merge 1e4119c8 rh/prompt-pcmode-avoid-eval-on-refname later to maint). - - * "git rebase" used a POSIX shell construct FreeBSD's /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 code points, 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). - - * Code paths 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 that 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 6127ff6 mw/symlinks later to maint.) - - * "git diff --quiet -- pathspec1 pathspec2" sometimes did not return - the 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 the no-done - extension was used. The fetching side waited for the list of - shallow boundary commits after the sending side 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). |
