The code now sanitizes the names - given to worktrees, to make sure these refs are well-formed. - - * "git merge" learned "--quit" option that cleans up the in-progress - merge while leaving the working tree and the index still in a mess. - - * "git format-patch" learns a configuration to set the default for - its --notes=<ref> option. - - * The code to show args with potential typo that cannot be - interpreted as a commit-ish has been improved. - - * "git clone --recurse-submodules" learned to set up the submodules - to ignore commit object names recorded in the superproject gitlink - and instead use the commits that happen to be at the tip of the - remote-tracking branches from the get-go, by passing the new - "--remote-submodules" option. - - * The pattern "git diff/grep" use to extract funcname and words - boundary for Matlab has been extend to cover Octave, which is more - or less equivalent. - - * "git help git" was hard to discover (well, at least for some - people). - - * The pattern "git diff/grep" use to extract funcname and words - boundary for Rust has been added. - - * "git status" can be told a non-standard default value for the - "--[no-]ahead-behind" option with a new configuration variable - status.aheadBehind. - - * "git fetch" and "git pull" reports when a fetch results in - non-fast-forward updates to let the user notice unusual situation. - The commands learned "--no-show-forced-updates" option to disable - this safety feature. - - * Two new commands "git switch" and "git restore" are introduced to - split "checking out a branch to work on advancing its history" and - "checking out paths out of the index and/or a tree-ish to work on - advancing the current history" out of the single "git checkout" - command. - - * "git branch --list" learned to always output the detached HEAD as - the first item (when the HEAD is detached, of course), regardless - of the locale. - - * The conditional inclusion mechanism learned to base the choice on - the branch the HEAD currently is on. - - * "git rev-list --objects" learned the "--no-object-names" option to - squelch the path to the object that is used as a grouping hint for - pack-objects. - - * A new tag.gpgSign configuration variable turns "git tag -a" into - "git tag -s". - - * "git multi-pack-index" learned expire and repack subcommands. - - * "git blame" learned to "ignore" commits in the history, whose - effects (as well as their presence) get ignored. - - * "git cherry-pick/revert" learned a new "--skip" action. - - * The tips of refs from the alternate object store can be used as - starting point for reachability computation now. - - * Extra blank lines in "git status" output have been reduced. - - * The commits in a repository can be described by multiple - commit-graph files now, which allows the commit-graph files to be - updated incrementally. - - * "git range-diff" output has been tweaked for easier identification - of which part of what file the patch shown is about. - - -Performance, Internal Implementation, Development Support etc. - - * Update supporting parts of "git rebase" to remove code that should - no longer be used. - - * Developer support to emulate unsatisfied prerequisites in tests to - ensure that the remainder of the tests still succeeds when tests - with prerequisites are skipped. - - * "git update-server-info" learned not to rewrite the file with the - same contents. - - * The way of specifying the path to find dynamic libraries at runtime - has been simplified. The old default to pass -R/path/to/dir has been - replaced with the new default to pass -Wl,-rpath,/path/to/dir, - which is the more recent GCC uses. Those who need to build with an - old GCC can still use "CC_LD_DYNPATH=-R" - - * Prepare use of reachability index in topological walker that works - on a range (A..B). - - * A new tutorial targeting specifically aspiring git-core - developers has been added. - - * Auto-detect how to tell HP-UX aCC where to use dynamically linked - libraries from at runtime. - - * "git mergetool" and its tests now spawn fewer subprocesses. - - * Dev support update to help tracing out tests. - - * Support to build with MSVC has been updated. - - * "git fetch" that grabs from a group of remotes learned to run the - auto-gc only once at the very end. - - * A handful of Windows build patches have been upstreamed. - - * The code to read state files used by the sequencer machinery for - "git status" has been made more robust against a corrupt or stale - state files. - - * "git for-each-ref" with multiple patterns have been optimized. - - * The tree-walk API learned to pass an in-core repository - instance throughout more codepaths. - - * When one step in multi step cherry-pick or revert is reset or - committed, the command line prompt script failed to notice the - current status, which has been improved. - - * Many GIT_TEST_* environment variables control various aspects of - how our tests are run, but a few followed "non-empty is true, empty - or unset is false" while others followed the usual "there are a few - ways to spell true, like yes, on, etc., and also ways to spell - false, like no, off, etc." convention. - - * Adjust the dir-iterator API and apply it to the local clone - optimization codepath. - - * We have been trying out a few language features outside c89; the - coding guidelines document did not talk about them and instead had - a blanket ban against them. - - * A test helper has been introduced to optimize preparation of test - repositories with many simple commits, and a handful of test - scripts have been updated to use it. - - -Fixes since v2.22 ------------------ - - * A relative pathname given to "git init --template=<path> <repo>" - ought to be relative to the directory "git init" gets invoked in, - but it instead was made relative to the repository, which has been - corrected. - - * "git worktree add" used to fail when another worktree connected to - the same repository was corrupt, which has been corrected. - - * The ownership rule for the file descriptor to fast-import remote - backend was mixed up, leading to an unrelated file descriptor getting - closed, which has been fixed. - - * A "merge -c" instruction during "git rebase --rebase-merges" should - give the user a chance to edit the log message, even when there is - otherwise no need to create a new merge and replace the existing - one (i.e. fast-forward instead), but did not. Which has been - corrected. - - * Code cleanup and futureproof. - - * More parameter validation. - - * "git update-server-info" used to leave stale packfiles in its - output, which has been corrected. - - * The server side support for "git fetch" used to show incorrect - value for the HEAD symbolic ref when the namespace feature is in - use, which has been corrected. - - * "git am -i --resolved" segfaulted after trying to see a commit as - if it were a tree, which has been corrected. - - * "git bundle verify" needs to see if prerequisite objects exist in - the receiving repository, but the command did not check if we are - in a repository upfront, which has been corrected. - - * "git merge --squash" is designed to update the working tree and the - index without creating the commit, and this cannot be countermanded - by adding the "--commit" option; the command now refuses to work - when both options are given. - - * The data collected by fsmonitor was not properly written back to - the on-disk index file, breaking t7519 tests occasionally, which - has been corrected. - - * Update to Unicode 12.1 width table. - - * The command line to invoke a "git cat-file" command from inside - "git p4" was not properly quoted to protect a caret and running a - broken command on Windows, which has been corrected. - - * "git request-pull" learned to warn when the ref we ask them to pull - from in the local repository and in the published repository are - different. - - * When creating a partial clone, the object filtering criteria is - recorded for the origin of the clone, but this incorrectly used a - hardcoded name "origin" to name that remote; it has been corrected - to honor the "--origin <name>" option. - - * "git fetch" into a lazy clone forgot to fetch base objects that are - necessary to complete delta in a thin packfile, which has been - corrected. - - * The filter_data used in the list-objects-filter (which manages a - lazily sparse clone repository) did not use the dynamic array API - correctly---'nr' is supposed to point at one past the last element - of the array in use. This has been corrected. - - * The description about slashes in gitignore patterns (used to - indicate things like "anchored to this level only" and "only - matches directories") has been revamped. - - * The URL decoding code has been updated to avoid going past the end - of the string while parsing %-<hex>-<hex> sequence. - - * The list of for-each like macros used by clang-format has been - updated. - - * "git branch --list" learned to show branches that are checked out - in other worktrees connected to the same repository prefixed with - '+', similar to the way the currently checked out branch is shown - with '*' in front. - (merge 6e9381469e nb/branch-show-other-worktrees-head later to maint). - - * Code restructuring during 2.20 period broke fetching tags via - "import" based transports. - - * The commit-graph file is now part of the "files that the runtime - may keep open file descriptors on, all of which would need to be - closed when done with the object store", and the file descriptor to - an existing commit-graph file now is closed before "gc" finalizes a - new instance to replace it. - - * "git checkout -p" needs to selectively apply a patch in reverse, - which did not work well. - - * Code clean-up to avoid signed integer wraparounds during binary search. - - * "git interpret-trailers" always treated '#' as the comment - character, regardless of core.commentChar setting, which has been - corrected. - - * "git stash show 23" used to work, but no more after getting - rewritten in C; this regression has been corrected. - - * "git rebase --abort" used to leave refs/rewritten/ when concluding - "git rebase -r", which has been corrected. - - * An incorrect list of options was cached after command line - completion failed (e.g. trying to complete a command that requires - a repository outside one), which has been corrected. - - * The code to parse scaled numbers out of configuration files has - been made more robust and also easier to follow. - - * The codepath to compute delta islands used to spew progress output - without giving the callers any way to squelch it, which has been - fixed. - - * Protocol capabilities that go over wire should never be translated, - but it was incorrectly marked for translation, which has been - corrected. The output of protocol capabilities for debugging has - been tweaked a bit. - - * Use "Erase in Line" CSI sequence that is already used in the editor - support to clear cruft in the progress output. - - * "git submodule foreach" did not protect command line options passed - to the command to be run in each submodule correctly, when the - "--recursive" option was in use. - - * The configuration variable rebase.rescheduleFailedExec should be - effective only while running an interactive rebase and should not - affect anything when running a non-interactive one, which was not - the case. This has been corrected. - - * The "git clone" documentation refers to command line options in its - description in the short form; they have been replaced with long - forms to make them more recognisable. - - * Generation of pack bitmaps are now disabled when .keep files exist, - as these are mutually exclusive features. - (merge 7328482253 ew/repack-with-bitmaps-by-default later to maint). - - * "git rm" to resolve a conflicted path leaked an internal message - "needs merge" before actually removing the path, which was - confusing. This has been corrected. - - * "git stash --keep-index" did not work correctly on paths that have - been removed, which has been fixed. - (merge b932f6a5e8 tg/stash-keep-index-with-removed-paths later to maint). - - * Window 7 update ;-) - - * A codepath that reads from GPG for signed object verification read - past the end of allocated buffer, which has been fixed. - - * "git clean" silently skipped a path when it cannot lstat() it; now - it gives a warning. - - * "git push --atomic" that goes over the transport-helper (namely, - the smart http transport) failed to prevent refs to be pushed when - it can locally tell that one of the ref update will fail without - having to consult the other end, which has been corrected. - - * The internal diff machinery can be made to read out of bounds while - looking for --function-context line in a corner case, which has been - corrected. - (merge b777f3fd61 jk/xdiff-clamp-funcname-context-index later to maint). - - * Other code cleanup, docfix, build fix, etc. - (merge fbec05c210 cc/test-oidmap later to maint). - (merge 7a06fb038c jk/no-system-includes-in-dot-c later to maint). - (merge 81ed2b405c cb/xdiff-no-system-includes-in-dot-c later to maint). - (merge d61e6ce1dd sg/fsck-config-in-doc later to maint). |
