We started this by first - deprecating and warning a pathspec that has such an element in - 2.11 (Nov 2016). - - * A hook script that is set unexecutable is simply ignored. Git - notifies when such a file is ignored, unless the message is - squelched via advice.ignoredHook configuration. - - * "git pull" has been taught to accept "--[no-]signoff" option and - pass it down to "git merge". - - * The "--push-option=<string>" option to "git push" now defaults to a - list of strings configured via push.pushOption variable. - - * "gitweb" checks if a directory is searchable with Perl's "-x" - operator, which can be enhanced by using "filetest 'access'" - pragma, which now we do. - - * "git stash save" has been deprecated in favour of "git stash push". - - * The set of paths output from "git status --ignored" was tied - closely with its "--untracked=<mode>" option, but now it can be - controlled more flexibly. Most notably, a directory that is - ignored because it is listed to be ignored in the ignore/exclude - mechanism can be handled differently from a directory that ends up - to be ignored only because all files in it are ignored. - - * The remote-helper for talking to MediaWiki has been updated to - truncate an overlong pagename so that ".mw" suffix can still be - added. - - * The remote-helper for talking to MediaWiki has been updated to - work with mediawiki namespaces. - - * The "--format=..." option "git for-each-ref" takes learned to show - the name of the 'remote' repository and the ref at the remote side - that is affected for 'upstream' and 'push' via "%(push:remotename)" - and friends. - - * Doc and message updates to teach users "bisect view" is a synonym - for "bisect visualize". - - * "git bisect run" that did not specify any command to run used to go - ahead and treated all commits to be tested as 'good'. This has - been corrected by making the command error out. - - * The SubmittingPatches document has been converted to produce an - HTML version via AsciiDoc/Asciidoctor. - - * We learned to optionally talk to a file system monitor via new - fsmonitor extension to speed up "git status" and other operations - that need to see which paths have been modified. Currently we only - support "watchman". See File System Monitor section of - git-update-index(1) for more detail. - - * The "diff" family of commands learned to ignore differences in - carriage return at the end of line. - - * Places that know about "sendemail.to", like documentation and shell - completion (in contrib/) have been taught about "sendemail.tocmd", - too. - - * "git add --renormalize ." is a new and safer way to record the fact - that you are correcting the end-of-line convention and other - "convert_to_git()" glitches in the in-repository data. - - * "git branch" and "git checkout -b" are now forbidden from creating - a branch whose name is "HEAD". - - * "git branch --list" learned to show its output through the pager by - default when the output is going to a terminal, which is controlled - by the pager.branch configuration variable. This is similar to a - recent change to "git tag --list". - - * "git grep -W", "git diff -W" and their friends learned a heuristic - to extend a pre-context beyond the line that matches the "function - pattern" (aka "diff.*.xfuncname") to include a comment block, if - exists, that immediately precedes it. - - * "git config --expiry-date gc.reflogexpire" can read "2.weeks" from - the configuration and report it as a timestamp, just like "--int" - would read "1k" and report 1024, to help consumption by scripts. - - * The shell completion (in contrib/) learned that "git pull" can take - the "--autostash" option. - - * The tagnames "git log --decorate" uses to annotate the commits can - now be limited to subset of available refs with the two additional - options, --decorate-refs[-exclude]=<pattern>. - - * "git grep" compiled with libpcre2 sometimes triggered a segfault, - which is being fixed. - - * "git send-email" tries to see if the sendmail program is available - in /usr/lib and /usr/sbin; extend the list of locations to be - checked to also include directories on $PATH. - - * "git diff" learned, "--anchored", a variant of the "--patience" - algorithm, to which the user can specify which 'unique' line to be - used as anchoring points. - - * The way "git worktree add" determines what branch to create from - where and checkout in the new worktree has been updated a bit. - - * Ancient part of codebase still shows dots after an abbreviated - object name just to show that it is not a full object name, but - these ellipses are confusing to people who newly discovered Git - who are used to seeing abbreviated object names and find them - confusing with the range syntax. - - * With a configuration variable rebase.abbreviateCommands set, - "git rebase -i" produces the todo list with a single-letter - command names. - - * "git worktree add" learned to run the post-checkout hook, just like - "git checkout" does, after the initial checkout. - - * "git svn" has been updated to strip CRs in the commit messages, as - recent versions of Subversion rejects them. - - * "git imap-send" did not correctly quote the folder name when - making a request to the server, which has been corrected. - - * Error messages from "git rebase" have been somewhat cleaned up. - - * Git has been taught to support an https:// URL used for http.proxy - when using recent versions of libcurl. - - * "git merge" learned to pay attention to merge.verifySignatures - configuration variable and pretend as if '--verify-signatures' - option was given from the command line. - - * "git describe" was taught to dig trees deeper to find a - <commit-ish>:<path> that refers to a given blob object. - - -Performance, Internal Implementation, Development Support etc. - - * An earlier update made it possible to use an on-stack in-core - lockfile structure (as opposed to having to deliberately leak an - on-heap one). Many codepaths have been updated to take advantage - of this new facility. - - * Calling cmd_foo() as if it is a general purpose helper function is - a no-no. Correct two instances of such to set an example. - - * We try to see if somebody runs our test suite with a shell that - does not support "local" like bash/dash does. - - * An early part of piece-by-piece rewrite of "git bisect" in C. - - * GSoC to piece-by-piece rewrite "git submodule" in C. - - * Optimize the code to find shortest unique prefix of object names. - - * Pathspec-limited revision traversal was taught not to keep finding - unneeded differences once it knows two trees are different inside - given pathspec. - - * Conversion from uchar[20] to struct object_id continues. - - * Code cleanup. - - * A single-word "unsigned flags" in the diff options is being split - into a structure with many bitfields. - - * TravisCI build updates. - - * Parts of a test to drive the long-running content filter interface - has been split into its own module, hopefully to eventually become - reusable. - - * Drop (perhaps overly cautious) sanity check before using the index - read from the filesystem at runtime. - - * The build procedure has been taught to avoid some unnecessary - instability in the build products. - - * A new mechanism to upgrade the wire protocol in place is proposed - and demonstrated that it works with the older versions of Git - without harming them. - - * An infrastructure to define what hash function is used in Git is - introduced, and an effort to plumb that throughout various - codepaths has been started. - - * The code to iterate over loose object files got optimized. - - * An internal function that was left for backward compatibility has - been removed, as there is no remaining callers. - - * Historically, the diff machinery for rename detection had a - hardcoded limit of 32k paths; this is being lifted to allow users - trade cycles with a (possibly) easier to read result. - - * The tracing infrastructure has been optimized for cases where no - tracing is requested. - - * In preparation for implementing narrow/partial clone, the object - walking machinery has been taught a way to tell it to "filter" some - objects from enumeration. - - * A few structures and variables that are implementation details of - the decorate API have been renamed and then the API got documented - better. - - * Assorted updates for TravisCI integration. - (merge 4f26366679 sg/travis-fixes later to maint). - - * Introduce a helper to simplify code to parse a common pattern that - expects either "--key" or "--key=<something>". - - * "git version --build-options" learned to report the host CPU and - the exact commit object name the binary was built from. - -Also contains various documentation updates and code clean-ups. - - -Fixes since v2.15 ------------------ - - * "auto" as a value for the columnar output configuration ought to - judge "is the output consumed by humans?" with the same criteria as - "auto" for coloured output configuration, i.e. either the standard - output stream is going to tty, or a pager is in use. We forgot the - latter, which has been fixed. - - * The experimental "color moved lines differently in diff output" - feature was buggy around "ignore whitespace changes" edges, which - has been corrected. - - * Instead of using custom line comparison and hashing functions to - implement "moved lines" coloring in the diff output, use the pair - of these functions from lower-layer xdiff/ code. - - * Some codepaths did not check for errors when asking what branch the - HEAD points at, which have been fixed. - - * "git commit", after making a commit, did not check for errors when - asking on what branch it made the commit, which has been corrected. - - * "git status --ignored -u" did not stop at a working tree of a - separate project that is embedded in an ignored directory and - listed files in that other project, instead of just showing the - directory itself as ignored. - - * A broken access to object databases in recent update to "git grep - --recurse-submodules" has been fixed. - - * A recent regression in "git rebase -i" that broke execution of git - commands from subdirectories via "exec" instruction has been fixed. - - * A (possibly flakey) test fix. - - * "git check-ref-format --branch @{-1}" bit a "BUG()" when run - outside a repository for obvious reasons; clarify the documentation - and make sure we do not even try to expand the at-mark magic in - such a case, but still call the validation logic for branch names. - - * "git fetch --recurse-submodules" now knows that submodules can be - moved around in the superproject in addition to getting updated, - and finds the ones that need to be fetched accordingly. - - * Command line completion (in contrib/) update. - - * Description of blame.{showroot,blankboundary,showemail,date} - configuration variables have been added to "git config --help". - - * After an error from lstat(), diff_populate_filespec() function - sometimes still went ahead and used invalid data in struct stat, - which has been fixed. - - * UNC paths are also relevant in Cygwin builds and they are now - tested just like Mingw builds. - - * Correct start-up sequence so that a repository could be placed - immediately under the root directory again (which was broken at - around Git 2.13). - - * The credential helper for libsecret (in contrib/) has been improved - to allow possibly prompting the end user to unlock secrets that are - currently locked (otherwise the secrets may not be loaded). - - * MinGW updates. - - * Error checking in "git imap-send" for empty response has been - improved. - - * Recent update to the refs infrastructure implementation started - rewriting packed-refs file more often than before; this has been - optimized again for most trivial cases. - - * Some error messages did not quote filenames shown in it, which have - been fixed. - - * "git rebase -i" recently started misbehaving when a submodule that - is configured with 'submodule.<name>.ignore' is dirty; this has - been corrected. - - * Building with NO_LIBPCRE1_JIT did not disable it, which has been fixed. - - * We used to add an empty alternate object database to the system - that does not help anything; it has been corrected. - - * Doc update around use of "format-patch --subject-prefix" etc. - - * A fix for an ancient bug in "git apply --ignore-space-change" codepath. - - * Clarify and enhance documentation for "merge-base --fork-point", as - it was clear what it computed but not why/what for. - - * A few scripts (both in production and tests) incorrectly redirected - their error output. These have been corrected. - - * "git notes" sent its error message to its standard output stream, - which was corrected. - - * The three-way merge performed by "git cherry-pick" was confused - when a new submodule was added in the meantime, which has been - fixed (or "papered over"). - - * The sequencer machinery (used by "git cherry-pick A..B", and "git - rebase -i", among other things) would have lost a commit if stopped - due to an unlockable index file, which has been fixed. - - * "git apply --inaccurate-eof" when used with "--ignore-space-change" - triggered an internal sanity check, which has been fixed. - - * Command line completion (in contrib/) has been taught about the - "--copy" option of "git branch". - - * When "git rebase" prepared a mailbox of changes and fed it to "git - am" to replay them, it was confused when a stray "From " happened - to be in the log message of one of the replayed changes. This has - been corrected. - - * There was a recent semantic mismerge in the codepath to write out a - section of a configuration section, which has been corrected. - - * Mentions of "git-rebase" and "git-am" (dashed form) still remained - in end-user visible strings emitted by the "git rebase" command; - they have been corrected. - - * Contrary to the documentation, "git pull -4/-6 other-args" did not - ask the underlying "git fetch" to go over IPv4/IPv6, which has been - corrected. - - * "git checkout --recursive" may overwrite and rewind the history of - the branch that happens to be checked out in submodule - repositories, which might not be desirable. Detach the HEAD but - still allow the recursive checkout to succeed in such a case. - (merge 57f22bf997 sb/submodule-recursive-checkout-detach-head later to maint). - - * "git branch --set-upstream" has been deprecated and (sort of) - removed, as "--set-upstream-to" is the preferred one these days. - The documentation still had "--set-upstream" listed on its - synopsis section, which has been corrected. - (merge a060f3d3d8 tz/branch-doc-remove-set-upstream later to maint). - - * Internally we use 0{40} as a placeholder object name to signal the - codepath that there is no such object (e.g. the fast-forward check - while "git fetch" stores a new remote-tracking ref says "we know - there is no 'old' thing pointed at by the ref, as we are creating - it anew" by passing 0{40} for the 'old' side), and expect that a - codepath to locate an in-core object to return NULL as a sign that - the object does not exist. A look-up for an object that does not - exist however is quite costly with a repository with large number - of packfiles. This access pattern has been optimized. - (merge 87b5e236a1 jk/fewer-pack-rescan later to maint). - - * In addition to "git stash -m message", the command learned to - accept "git stash -mmessage" form. - (merge 5675473fcb ph/stash-save-m-option-fix later to maint). - - * @{-N} in "git checkout @{-N}" may refer to a detached HEAD state, - but the documentation was not clear about it, which has been fixed. - (merge 75ce149575 ks/doc-checkout-previous later to maint). - - * A regression in the progress eye-candy was fixed. - (merge 9c5951cacf jk/progress-delay-fix later to maint). - - * The code internal to the recursive merge strategy was not fully - prepared to see a path that is renamed to try overwriting another - path that is only different in case on case insensitive systems. - This does not matter in the current code, but will start to matter - once the rename detection logic starts taking hints from nearby - paths moving to some directory and moves a new path along with them. - (merge 4cba2b0108 en/merge-recursive-icase-removal later to maint). - - * An v2.12-era regression in pathspec match logic, which made it look - into submodule tree even when it is not desired, has been fixed. - (merge eef3df5a93 bw/pathspec-match-submodule-boundary later to maint). - - * Amending commits in git-gui broke the author name that is non-ascii - due to incorrect encoding conversion. - - * Recent update to the submodule configuration code broke "diff-tree" - by accidentally stopping to read from the index upfront. - (merge fd66bcc31f bw/submodule-config-cleanup later to maint). - - * Git shows a message to tell the user that it is waiting for the - user to finish editing when spawning an editor, in case the editor - opens to a hidden window or somewhere obscure and the user gets - lost. - (merge abfb04d0c7 ls/editor-waiting-message later to maint). - - * The "safe crlf" check incorrectly triggered for contents that does - not use CRLF as line endings, which has been corrected. - (merge 649f1f0948 tb/check-crlf-for-safe-crlf later to maint). - - * "git clone --shared" to borrow from a (secondary) worktree did not - work, even though "git clone --local" did. Both are now accepted. - (merge b3b05971c1 es/clone-shared-worktree later to maint). - - * The build procedure now allows not just the repositories but also - the refs to be used to take pre-formatted manpages and html - documents to install. - (merge 65289e9dcd rb/quick-install-doc later to maint). - - * Update the shell prompt script (in contrib/) to strip trailing CR - from strings read from various "state" files. - (merge 041fe8fc83 ra/prompt-eread-fix later to maint). - - * "git merge -s recursive" did not correctly abort when the index is - dirty, if the merged tree happened to be the same as the current - HEAD, which has been fixed. - - * Bytes with high-bit set were encoded incorrectly and made - credential helper fail. - (merge 4c267f2ae3 jd/fix-strbuf-add-urlencode-bytes later to maint). - - * "git rebase -p -X<option>" did not propagate the option properly - down to underlying merge strategy backend. - (merge dd6fb0053c js/fix-merge-arg-quoting-in-rebase-p later to maint). - - * "git merge -s recursive" did not correctly abort when the index is - dirty, if the merged tree happened to be the same as the current - HEAD, which has been fixed. - (merge f309e8e768 ew/empty-merge-with-dirty-index-maint later to maint). - - * Other minor doc, test and build updates and code cleanups. - (merge 1a1fc2d5b5 rd/man-prune-progress later to maint). - (merge 0ba014035a rd/man-reflog-add-n later to maint). - (merge e54b63359f rd/doc-notes-prune-fix later to maint). - (merge ff4c9b413a sp/doc-info-attributes later to maint). - (merge 7db2cbf4f1 jc/receive-pack-hook-doc later to maint). - (merge 5a0526264b tg/t-readme-updates later to maint). - (merge 5e83cca0b8 jk/no-optional-locks later to maint). - (merge 826c778f7c js/hashmap-update-sample later to maint). - (merge 176b2d328c sg/setup-doc-update later to maint). - (merge 1b09073514 rs/am-builtin-leakfix later to maint). - (merge addcf6cfde rs/fmt-merge-msg-string-leak-fix later to maint). - (merge c3ff8f6c14 rs/strbuf-read-once-reset-length later to maint). - (merge 6b0eb884f9 db/doc-workflows-neuter-the-maintainer later to maint). - (merge 8c87bdfb21 jk/cvsimport-quoting later to maint). - (merge 176cb979fe rs/fmt-merge-msg-leakfix later to maint). - (merge 5a03360e73 tb/delimit-pretty-trailers-args-with-comma later to maint). - (merge d0e6326026 ot/pretty later to maint). - (merge 44103f4197 sb/test-helper-excludes later to maint). - (merge 170078693f jt/transport-no-more-rsync later to maint). - (merge c07b3adff1 bw/path-doc later to maint). - (merge bf9d7df950 tz/lib-git-svn-svnserve-tests later to maint). - (merge dec366c9a8 sr/http-sslverify-config-doc later to maint). - (merge 3f824e91c8 jk/test-suite-tracing later to maint). - (merge 1feb061701 db/doc-config-section-names-with-bs later to maint). - (merge 74dea0e13c jh/memihash-opt later to maint). - (merge 2e9fdc795c ma/bisect-leakfix later to maint). |
