Branch: CURRENT, Version: 2.33.1, Package name: git-base-2.33.1, Maintainer: pkgsrc-users

Git is a free and open source distributed version control system
designed to handle everything from small to very large projects with
speed and efficiency.

Git is easy to learn and has a tiny footprint with lightning fast
performance. It outclasses SCM tools like Subversion, CVS, Perforce,
and ClearCase with features like cheap local branching, convenient
staging areas, and multiple workflows.

This package contains only the git program (and subcommands). It does
not contain man pages or the tk-based repository browser.

Git 2.33.1 Release Notes

This primarily is to backport various fixes accumulated during the
development towards Git 2.34, the next feature release.

Fixes since v2.33

 * The unicode character width table (used for output alignment) has
   been updated.

 * Input validation of "git pack-objects --stdin-packs" has been

 * Bugfix for common ancestor negotiation recently introduced in "git
   push" codepath.

 * "git pull" had various corner cases that were not well thought out
   around its --rebase backend, e.g. "git pull --ff-only" did not stop
   but went ahead and rebased when the history on other side is not a
   descendant of our history.  The series tries to fix them up.

 * "git apply" miscounted the bytes and failed to read to the end of
   binary hunks.

 * "git range-diff" code clean-up.

 * "git commit --fixup" now works with "--edit" again, after \ 
it was
   broken in v2.32.

 * Use upload-artifacts v1 (instead of v2) for 32-bit linux, as the
   new version has a blocker bug for that architecture.

 * Checking out all the paths from HEAD during the last conflicted
   step in "git rebase" and continuing would cause the step to be
   skipped (which is expected), but leaves MERGE_MSG file behind in
   $GIT_DIR and confuses the next "git commit", which has been

 * Various bugs in "git rebase -r" have been fixed.

 * mmap() imitation used to call xmalloc() that dies upon malloc()
   failure, which has been corrected to just return an error to the
   caller to be handled.

 * "git diff --relative" segfaulted and/or produced incorrect result
   when there are unmerged paths.

 * The delayed checkout code path in "git checkout" etc. were chatty
   even when --quiet and/or --no-progress options were given.

 * "git branch -D <branch>" used to refuse to remove a broken branch
   ref that points at a missing commit, which has been corrected.

 * Build update for Apple clang.

 * The parser for the "--nl" option of "git column" has been

 * "git upload-pack" which runs on the other side of "git fetch"
   forgot to take the ref namespaces into account when handling
   want-ref requests.

 * The sparse-index support can corrupt the index structure by storing
   a stale and/or uninitialized data, which has been corrected.

 * Buggy tests could damage repositories outside the throw-away test
   area we created.  We now by default export GIT_CEILING_DIRECTORIES
   to limit the damage from such a stray test.

 * Even when running "git send-email" without its own threaded
   discussion support, a threading related header in one message is
   carried over to the subsequent message to result in an unwanted
   threading, which has been corrected.

 * The output from "git fast-export", when its anonymization feature
   is in use, showed an annotated tag incorrectly.

 * Recent "diff -m" changes broke "gitk", which has been \ 

 * "git maintenance" scheduler fix for macOS.

 * A pathname in an advice message has been made cut-and-paste ready.

 * The "git apply -3" code path learned not to bother the lower level
   merge machinery when the three-way merge can be trivially resolved
   without the content level merge.

 * The code that optionally creates the *.rev reverse index file has
   been optimized to avoid needless computation when it is not writing
   the file out.

 * "git range-diff -I... <range> <range>" segfaulted, \ 
which has been

 * The order in which various files that make up a single (conceptual)
   packfile has been reevaluated and straightened up.  This matters in
   correctness, as an incomplete set of files must not be shown to a
   running Git.

 * The "mode" word is useless in a call to open(2) that does not
   create a new file.  Such a call in the files backend of the ref
   subsystem has been cleaned up.

 * "git update-ref --stdin" failed to flush its output as needed,
   which potentially led the conversation to a deadlock.

 * When "git am --abort" fails to abort correctly, it still exited
   with exit status of 0, which has been corrected.

 * Correct nr and alloc members of strvec struct to be of type size_t.

 * "git stash", where the tentative change involves changing a
   directory to a file (or vice versa), was confused, which has been

 * "git clone" from a repository whose HEAD is unborn into a bare
   repository didn't follow the branch name the other side used, which
   is corrected.

 * "git cvsserver" had a long-standing bug in its authentication code,
   which has finally been corrected (it is unclear and is a separate
   question if anybody is seriously using it, though).

 * "git difftool --dir-diff" mishandled symbolic links.

 * Sensitive data in the HTTP trace were supposed to be redacted, but
   we failed to do so in HTTP/2 requests.

 * "make clean" has been updated to remove leftover .depend/
   directories, even when it is not told to use them to compute header

 * Protocol v0 clients can get stuck parsing a malformed feature line.

Also contains various documentation updates and code clean-ups.

PR 55225 from Benjamin Lorenz: git push not displaying username

Seems that the input code depends on a HAVE_DEV_TTY setting that
autoconf doesn't actually check. I guess Linux packagers set this
explicitly; we shall too. Otherwise it falls back to libc getpass()
for all input, which disables echo unconditionally.

Git 2.32 Release Notes

Backward compatibility notes

 * ".gitattributes", ".gitignore", and ".mailmap" \ 
files that are
   symbolic links are ignored.

 * "git apply --3way" used to first attempt a straight application,
   and only fell back to the 3-way merge algorithm when the stright
   application failed.  Starting with this version, the command will
   first try the 3-way merge algorithm and only when it fails (either
   resulting with conflict or the base versions of blobs are missing),
   falls back to the usual patch application.

Updates since v2.31

UI, Workflows & Features

 * It does not make sense to make ".gitattributes", \ 
".gitignore" and
   ".mailmap" symlinks, as they are supposed to be usable from the
   object store (think: bare repositories where HEAD:.mailmap etc. are
   used).  When these files are symbolic links, we used to read the
   contents of the files pointed by them by mistake, which has been

 * "git stash show" learned to optionally show untracked part of the

 * "git log --format='...'" learned "%(describe)" placeholder.

 * "git repack" so far has been only capable of repacking everything
   under the sun into a single pack (or split by size).  A cleverer
   strategy to reduce the cost of repacking a repository has been

 * The http codepath learned to let the credential layer to cache the
   password used to unlock a certificate that has successfully been

 * "git commit --fixup=<commit>", which was to tweak the changes made
   to the contents while keeping the original log message intact,
   learned "--fixup=(amend|reword):<commit>", that can be used to
   tweak both the message and the contents, and only the message,

 * "git send-email" learned to honor the core.hooksPath configuration.

 * "git format-patch -v<n>" learned to allow a reroll count that is
   not an integer.

 * "git commit" learned "--trailer \ 
<key>[=<value>]" option; together
   with the interpret-trailers command, this will make it easier to
   support custom trailers.

 * "git clone --reject-shallow" option fails the clone as soon as we
   notice that we are cloning from a shallow repository.

 * A configuration variable has been added to force tips of certain
   refs to be given a reachability bitmap.

 * "gitweb" learned "e-mail privacy" feature to redact \ 
strings that
   look like e-mail addresses on various pages.

 * "git apply --3way" has always been "to fall back to 3-way merge
   only when straight application fails". Swap the order of falling
   back so that 3-way is always attempted first (only when the option
   is given, of course) and then straight patch application is used as
   a fallback when it fails.

 * "git apply" now takes "--3way" and "--cached" \ 
at the same time, and
   work and record results only in the index.

 * The command line completion (in contrib/) has learned that
   CHERRY_PICK_HEAD is a possible pseudo-ref.

 * Userdiff patterns for "Scheme" has been added.

 * "git log" learned "--diff-merges=<style>" option, \ 
with an
   associated configuration variable log.diffMerges.

 * "git log --format=..." placeholders learned %ah/%ch placeholders to
   request the --date=human output.

 * Replace GIT_CONFIG_NOSYSTEM mechanism to decline from reading the
   system-wide configuration file with GIT_CONFIG_SYSTEM that lets
   users specify from which file to read the system-wide configuration
   (setting it to an empty file would essentially be the same as
   setting NOSYSTEM), and introduce GIT_CONFIG_GLOBAL to override the
   per-user configuration in $HOME/.gitconfig.

 * "git add" and "git rm" learned not to touch those paths \ 
that are
   outside of sparse checkout.

 * "git rev-list" learns the \ 
"--filter=object:type=<type>" option,
   which can be used to exclude objects of the given kind from the
   packfile generated by pack-objects.

 * The command line completion (in contrib/) for "git stash" has been

 * "git subtree" updates.

 * It is now documented that "format-patch" skips merges.

 * Options to "git pack-objects" that take numeric values like
   --window and --depth should not accept negative values; the input
   validation has been tightened.

 * The way the command line specified by the trailer.<token>.command
   configuration variable receives the end-user supplied value was
   both error prone and misleading.  An alternative to achieve the
   same goal in a safer and more intuitive way has been added, as
   the trailer.<token>.cmd configuration variable, to replace it.

 * "git add -i --dry-run" does not dry-run, which was surprising.  The
   combination of options has taught to error out.

 * "git push" learns to discover common ancestor with the receiving
   end over protocol v2.  This will hopefully make "git push" as
   efficient as "git fetch" in avoiding objects from getting
   transferred unnecessarily.

 * "git mailinfo" (hence "git am") learned the \ 
"--quoted-cr" option to
   control how lines ending with CRLF wrapped in base64 or qp are

Performance, Internal Implementation, Development Support etc.

 * Rename detection rework continues.

 * GIT_TEST_FAIL_PREREQS is a mechanism to skip test pieces with
   prerequisites to catch broken tests that depend on the side effects
   of optional pieces, but did not work at all when negative
   prerequisites were involved.
   (merge 27d578d904 jk/fail-prereq-testfix later to maint).

 * "git diff-index" codepath has been taught to trust fsmonitor status
   to reduce number of lstat() calls.
   (merge 7e5aa13d2c nk/diff-index-fsmonitor later to maint).

 * Reorganize Makefile to allow building git.o and other essential
   objects without extra stuff needed only for testing.

 * Preparatory API changes for parallel checkout.

 * A simple IPC interface gets introduced to build services like
   fsmonitor on top.

 * Fsck API clean-up.

 * SECURITY.md that is facing individual contributors and end users
   has been introduced.  Also a procedure to follow when preparing
   embargoed releases has been spelled out.
   (merge 09420b7648 js/security-md later to maint).

 * Optimize "rev-list --use-bitmap-index --objects" corner case that
   uses negative tags as the stopping points.

 * CMake update for vsbuild.

 * An on-disk reverse-index to map the in-pack location of an object
   back to its object name across multiple packfiles is introduced.

 * Generate [ec]tags under $(QUIET_GEN).

 * Clean-up codepaths that implements "git send-email --validate"
   option and improves the message from it.

 * The last remnant of gettext-poison has been removed.

 * The test framework has been taught to optionally turn the default
   merge strategy to "ort" throughout the system where we use
   three-way merges internally, like cherry-pick, rebase etc.,
   primarily to enhance its test coverage (the strategy has been
   available as an explicit "-s ort" choice).

 * A bit of code clean-up and a lot of test clean-up around userdiff

 * Handling of "promisor packs" that allows certain objects to be
   missing and lazily retrievable has been optimized (a bit).

 * When packet_write() fails, we gave an extra error message
   unnecessarily, which has been corrected.

 * The checkout machinery has been taught to perform the actual
   write-out of the files in parallel when able.

 * Show errno in the trace output in the error codepath that calls
   read_raw_ref method.

 * Effort to make the command line completion (in contrib/) safe with
   "set -u" continues.

 * Tweak a few tests for "log --format=..." that show timestamps in
   various formats.

 * The reflog expiry machinery has been taught to emit trace events.

 * Over-the-wire protocol learns a new request type to ask for object
   sizes given a list of object names.

Fixes since v2.31

 * The fsmonitor interface read from its input without making sure
   there is something to read from.  This bug is new in 2.31

 * The data structure used by fsmonitor interface was not properly
   duplicated during an in-core merge, leading to use-after-free etc.

 * "git bisect" reimplemented more in C during 2.30 timeframe did not
   take an annotated tag as a good/bad endpoint well.  This regression
   has been corrected.

 * Fix macros that can silently inject unintended null-statements.

 * CALLOC_ARRAY() macro replaces many uses of xcalloc().

 * Update insn in Makefile comments to run fuzz-all target.

 * Fix a corner case bug in "git mv" on case insensitive systems,
   which was introduced in 2.29 timeframe.

 * We had a code to diagnose and die cleanly when a required
   clean/smudge filter is missing, but an assert before that
   unnecessarily fired, hiding the end-user facing die() message.
   (merge 6fab35f748 mt/cleanly-die-upon-missing-required-filter later to maint).

 * Update C code that sets a few configuration variables when a remote
   is configured so that it spells configuration variable names in the
   canonical camelCase.
   (merge 0f1da600e6 ab/remote-write-config-in-camel-case later to maint).

 * A new configuration variable has been introduced to allow choosing
   which version of the generation number gets used in the
   commit-graph file.
   (merge 702110aac6 ds/commit-graph-generation-config later to maint).

 * Perf test update to work better in secondary worktrees.
   (merge 36e834abc1 jk/perf-in-worktrees later to maint).

 * Updates to memory allocation code around the use of pcre2 library.
   (merge c1760352e0 ab/grep-pcre2-allocfix later to maint).

 * "git -c core.bare=false clone --bare ..." would have segfaulted,
   which has been corrected.
   (merge 75555676ad bc/clone-bare-with-conflicting-config later to maint).

 * When "git checkout" removes a path that does not exist in the
   commit it is checking out, it wasn't careful enough not to follow
   symbolic links, which has been corrected.
   (merge fab78a0c3d mt/checkout-remove-nofollow later to maint).

 * A few option description strings started with capital letters,
   which were corrected.
   (merge 5ee90326dc cc/downcase-opt-help later to maint).

 * Plug or annotate remaining leaks that trigger while running the
   very basic set of tests.
   (merge 68ffe095a2 ah/plugleaks later to maint).

 * The hashwrite() API uses a buffering mechanism to avoid calling
   write(2) too frequently. This logic has been refactored to be
   easier to understand.
   (merge ddaf1f62e3 ds/clarify-hashwrite later to maint).

 * "git cherry-pick/revert" with or without "--[no-]edit" \ 
did not spawn
   the editor as expected (e.g. "revert --no-edit" after a conflict
   still asked to edit the message), which has been corrected.
   (merge 39edfd5cbc en/sequencer-edit-upon-conflict-fix later to maint).

 * "git daemon" has been tightened against systems that take backslash
   as directory separator.
   (merge 9a7f1ce8b7 rs/daemon-sanitize-dir-sep later to maint).

 * A NULL-dereference bug has been corrected in an error codepath in
   "git for-each-ref", "git branch --list" etc.
   (merge c685450880 jk/ref-filter-segfault-fix later to maint).

 * Streamline the codepath to fix the UTF-8 encoding issues in the
   argv[] and the prefix on macOS.
   (merge c7d0e61016 tb/precompose-prefix-simplify later to maint).

 * The command-line completion script (in contrib/) had a couple of
   references that would have given a warning under the "-u" (nounset)
   (merge c5c0548d79 vs/completion-with-set-u later to maint).

 * When "git pack-objects" makes a literal copy of a part of existing
   packfile using the reachability bitmaps, its update to the progress
   meter was broken.
   (merge 8e118e8490 jk/pack-objects-bitmap-progress-fix later to maint).

 * The dependencies for config-list.h and command-list.h were broken
   when the former was split out of the latter, which has been
   (merge 56550ea718 sg/bugreport-fixes later to maint).

 * "git push --quiet --set-upstream" was not quiet when setting the
   upstream branch configuration, which has been corrected.
   (merge f3cce896a8 ow/push-quiet-set-upstream later to maint).

 * The prefetch task in "git maintenance" assumed that "git \ 
   from any remote would fetch all its local branches, which would
   fetch too much if the user is interested in only a subset of
   branches there.
   (merge 32f67888d8 ds/maintenance-prefetch-fix later to maint).

 * Clarify that pathnames recorded in Git trees are most often (but
   not necessarily) encoded in UTF-8.
   (merge 9364bf465d ab/pathname-encoding-doc later to maint).

 * "git --config-env var=val cmd" weren't accepted (only
   --config-env=var=val was).
   (merge c331551ccf ps/config-env-option-with-separate-value later to maint).

 * When the reachability bitmap is in effect, the "do not lose
   recently created objects and those that are reachable from them"
   safety to protect us from races were disabled by mistake, which has
   been corrected.
   (merge 2ba582ba4c jk/prune-with-bitmap-fix later to maint).

 * Cygwin pathname handling fix.
   (merge bccc37fdc7 ad/cygwin-no-backslashes-in-paths later to maint).

 * "git rebase --[no-]reschedule-failed-exec" did not work well with
   its configuration variable, which has been corrected.
   (merge e5b32bffd1 ab/rebase-no-reschedule-failed-exec later to maint).

 * Portability fix for command line completion script (in contrib/).
   (merge f2acf763e2 si/zsh-complete-comment-fix later to maint).

 * "git repack -A -d" in a partial clone unnecessarily loosened
   objects in promisor pack.

 * "git bisect skip" when custom words are used for new/old did not
   work, which has been corrected.

 * A few variants of informational message "Already up-to-date" has
   been rephrased.
   (merge ad9322da03 js/merge-already-up-to-date-message-reword later to maint).

 * "git submodule update --quiet" did not propagate the quiet option
   down to underlying "git fetch", which has been corrected.
   (merge 62af4bdd42 nc/submodule-update-quiet later to maint).

 * Document that our test can use "local" keyword.
   (merge a84fd3bcc6 jc/test-allows-local later to maint).

 * The word-diff mode has been taught to work better with a word
   regexp that can match an empty string.
   (merge 0324e8fc6b pw/word-diff-zero-width-matches later to maint).

 * "git p4" learned to find branch points more efficiently.
   (merge 6b79818bfb jk/p4-locate-branch-point-optim later to maint).

 * When "git update-ref -d" removes a ref that is packed, it left
   empty directories under $GIT_DIR/refs/ for
   (merge 5f03e5126d wc/packed-ref-removal-cleanup later to maint).

 * "git clean" and "git ls-files -i" had confusion around \ 
working on
   or showing ignored paths inside an ignored directory, which has
   been corrected.
   (merge b548f0f156 en/dir-traversal later to maint).

 * The handling of "%(push)" formatting element of \ 
"for-each-ref" and
   friends was broken when the same codepath started handling
   "%(push:<what>)", which has been corrected.
   (merge 1e1c4c5eac zh/ref-filter-push-remote-fix later to maint).

 * The bash prompt script (in contrib/) did not work under "set -u".
   (merge 5c0cbdb107 en/prompt-under-set-u later to maint).

 * The "chainlint" feature in the test framework is a handy way to
   catch common mistakes in writing new tests, but tends to get
   expensive.  An knob to selectively disable it has been introduced
   to help running tests that the developer has not modified.
   (merge 2d86a96220 jk/test-chainlint-softer later to maint).

 * The "rev-parse" command did not diagnose the lack of argument to
   "--path-format" option, which was introduced in v2.31 era, which
   has been corrected.
   (merge 99fc555188 wm/rev-parse-path-format-wo-arg later to maint).

Git 2.31.1 Release Notes

Fixes since v2.31

   there is something to read from.  This bug is new in 2.31

 * The data structure used by fsmonitor interface was not properly
   duplicated during an in-core merge, leading to use-after-free etc.

   which was introduced in 2.29 timeframe.

Also contains various documentation updates and code clean-ups.

Git 2.31 Release Notes

Updates since v2.30

Backward incompatible and other important changes

 * The "pack-redundant" command, which has been left stale with almost
   unusable performance issues, now warns loudly when it gets used, as
   we no longer want to recommend its use (instead just "repack -d"

 * The development community has adopted Contributor Covenant v2.0 to
   update from v1.4 that we have been using.

 * The support for deprecated PCRE1 library has been dropped.

 * Fixes for CVE-2021-21300 in Git 2.30.2 (and earlier) is included.

UI, Workflows & Features

 * The "--format=%(trailers)" mechanism gets enhanced to make it
   easier to design output for machine consumption.

 * When a user does not tell "git pull" to use rebase or merge, the
   command gives a loud message telling a user to choose between
   rebase or merge but creates a merge anyway, forcing users who would
   want to rebase to redo the operation.  Fix an early part of this
   problem by tightening the condition to give the message---there is
   no reason to stop or force the user to choose between rebase or
   merge if the history fast-forwards.

 * The configuration variable 'core.abbrev' can be set to 'no' to
   force no abbreviation regardless of the hash algorithm.

 * "git rev-parse" can be explicitly told to give output as absolute
   or relative path with the `--path-format=(absolute|relative)` option.

 * Bash completion (in contrib/) update to make it easier for
   end-users to add completion for their custom "git" subcommands.

 * "git maintenance" learned to drive scheduled maintenance on
   platforms whose native scheduling methods are not 'cron'.

 * After expiring a reflog and making a single commit, the reflog for
   the branch would record a single entry that knows both @{0} and
   @{1}, but we failed to answer "what commit were we on?", i.e. @{1}

 * "git bundle" learns "--stdin" option to read its refs from the
   standard input.  Also, it now does not lose refs whey they point
   at the same object.

 * "git log" learned a new "--diff-merges=<how>" option.

 * "git ls-files" can and does show multiple entries when the index is
   unmerged, which is a source for confusion unless -s/-u option is in
   use.  A new option --deduplicate has been introduced.

 * `git worktree list` now annotates worktrees as prunable, shows
   locked and prunable attributes in --porcelain mode, and gained
   a --verbose option.

 * "git clone" tries to locally check out the branch pointed at by
   HEAD of the remote repository after it is done, but the protocol
   did not convey the information necessary to do so when copying an
   empty repository.  The protocol v2 learned how to do so.

 * There are other ways than ".." for a single token to denote a
   "commit range", namely "<rev>^!" and \ 
"<rev>^-<n>", but "git
   range-diff" did not understand them.

 * The "git range-diff" command learned \ 
"--(left|right)-only" option
   to show only one side of the compared range.

 * "git mergetool" feeds three versions (base, local and remote) of
   a conflicted path unmodified.  The command learned to optionally
   prepare these files with unconflicted parts already resolved.

 * The .mailmap is documented to be read only from the root level of a
   working tree, but a stray file in a bare repository also was read
   by accident, which has been corrected.

 * "git maintenance" tool learned a new "pack-refs" \ 
maintenance task.

 * The error message given when a configuration variable that is
   expected to have a boolean value has been improved.

 * Signed commits and tags now allow verification of objects, whose
   two object names (one in SHA-1, the other in SHA-256) are both

 * "git rev-list" command learned "--disk-usage" option.

 * "git {diff,log} --{skip,rotate}-to=<path>" allows the user to
   discard diff output for early paths or move them to the end of the

 * "git difftool" learned "--skip-to=<path>" option to \ 
restart an
   interrupted session from an arbitrary path.

 * "git grep" has been tweaked to be limited to the sparse checkout

 * "git rebase --[no-]fork-point" gained a configuration variable
   rebase.forkPoint so that users do not have to keep specifying a
   non-default setting.

Performance, Internal Implementation, Development Support etc.

 * A 3-year old test that was not testing anything useful has been

 * Retire more names with "sha1" in it.

 * The topological walk codepath is covered by new trace2 stats.

 * Update the Code-of-conduct to version 2.0 from the upstream (we've
   been using version 1.4).

 * "git mktag" validates its input using its own rules before writing
   a tag object---it has been updated to share the logic with "git

 * Two new ways to feed configuration variable-value pairs via
   environment variables have been introduced, and the way
   GIT_CONFIG_PARAMETERS encodes variable/value pairs has been tweaked
   to make it more robust.

 * Tests have been updated so that they do not to get affected by the
   name of the default branch "git init" creates.

 * "git fetch" learns to treat ref updates atomically in all-or-none
   fashion, just like "git push" does, with the new \ 
"--atomic" option.

 * The peel_ref() API has been replaced with peel_iterated_oid().

 * The .use_shell flag in struct child_process that is passed to
   run_command() API has been clarified with a bit more documentation.

 * Document, clean-up and optimize the code around the cache-tree
   extension in the index.

 * The ls-refs protocol operation has been optimized to narrow the
   sub-hierarchy of refs/ it walks to produce response.

 * When removing many branches and tags, the code used to do so one
   ref at a time.  There is another API it can use to delete multiple
   refs, and it makes quite a lot of performance difference when the
   refs are packed.

 * The "pack-objects" command needs to iterate over all the tags when
   automatic tag following is enabled, but it actually iterated over
   all refs and then discarded everything outside "refs/tags/"
   hierarchy, which was quite wasteful.

 * A perf script was made more portable.

 * Our setting of GitHub CI test jobs were a bit too eager to give up
   once there is even one failure found.  Tweak the knob to allow
   other jobs keep running even when we see a failure, so that we can
   find more failures in a single run.

 * We've carried compatibility codepaths for compilers without
   variadic macros for quite some time, but the world may be ready for
   them to be removed.  Force compilation failure on exotic platforms
   where variadic macros are not available to find out who screams in
   such a way that we can easily revert if it turns out that the world
   is not yet ready.

 * Code clean-up to ensure our use of hashtables using object names as
   keys use the "struct object_id" objects, not the raw hash values.

 * Lose the debugging aid that may have been useful in the past, but
   no longer is, in the "grep" codepaths.

 * Some pretty-format specifiers do not need the data in commit object
   (e.g. "%H"), but we were over-eager to load and parse it, which has
   been made even lazier.

 * Get rid of "GETTEXT_POISON" support altogether, which may or may
   not be controversial.

 * Introduce an on-disk file to record revindex for packdata, which
   traditionally was always created on the fly and only in-core.

 * The commit-graph learned to use corrected commit dates instead of
   the generation number to help topological revision traversal.

 * Piecemeal of rewrite of "git bisect" in C continues.

 * When a pager spawned by us exited, the trace log did not record its
   exit status correctly, which has been corrected.

 * Removal of GIT_TEST_GETTEXT_POISON continues.

 * The code to implement "git merge-base --independent" was poorly
   done and was kept from the very beginning of the feature.

 * Preliminary changes to fsmonitor integration.

 * Performance improvements for rename detection.

 * The common code to deal with "chunked file format" that is shared
   by the multi-pack-index and commit-graph files have been factored
   out, to help codepaths for both filetypes to become more robust.

 * The approach to "fsck" the incoming objects in "index-pack" is
   attractive for performance reasons (we have them already in core,
   inflated and ready to be inspected), but fundamentally cannot be
   applied fully when we receive more than one pack stream, as a tree
   object in one pack may refer to a blob object in another pack as
   ".gitmodules", when we want to inspect blobs that are used as
   ".gitmodules" file, for example.  Teach "index-pack" to emit
   objects that must be inspected later and check them in the calling
   "fetch-pack" process.

 * The logic to handle "trailer" related placeholders in the
   "--format=" mechanisms in the "log" family and \ 
   family is getting unified.

 * Raise the buffer size used when writing the index file out from
   (obviously too small) 8kB to (clearly sufficiently large) 128kB.

 * It is reported that open() on some platforms (e.g. macOS Big Sur)
   can return EINTR even though our timers are set up with SA_RESTART.
   A workaround has been implemented and enabled for macOS to rerun
   open() transparently from the caller when this happens.

Fixes since v2.30

 * Diagnose command line error of "git rebase" early.

 * Clean up option descriptions in "git cmd --help".

 * "git stash" did not work well in a sparsely checked out working

 * Some tests expect that "ls -l" output has either '-' or 'x' for
   group executable bit, but setgid bit can be inherited from parent
   directory and make these fields 'S' or 's' instead, causing test

 * "git for-each-repo --config=<var> <cmd>" should not run \ 
<cmd> for
   any repository when the configuration variable <var> is not defined
   even once.

 * Fix 2.29 regression where "git mergetool --tool-help" fails to list
   all the available tools.

 * Fix for procedure to building CI test environment for mac.

 * The implementation of "git branch --sort" wrt the detached HEAD
   display has always been hacky, which has been cleaned up.

 * Newline characters in the host and path part of git:// URL are
   now forbidden.

 * "git diff" showed a submodule working tree with untracked cruft as
   "Submodule commit <objectname>-dirty", but a natural \ 
expectation is
   that the "-dirty" indicator would align with "git describe \ 
   which does not consider having untracked files in the working tree
   as source of dirtiness.  The inconsistency has been fixed.

 * When more than one commit with the same patch ID appears on one
   side, "git log --cherry-pick A...B" did not exclude them all when a
   commit with the same patch ID appears on the other side.  Now it

 * Documentation for "git fsck" lost stale bits that has become

 * Doc fix for packfile URI feature.

 * When "git rebase -i" processes "fixup" insn, there is no \ 
reason to
   clean up the commit log message, but we did the usual stripspace
   processing.  This has been corrected.
   (merge f7d42ceec5 js/rebase-i-commit-cleanup-fix later to maint).

 * Fix in passing custom args from "git clone" to \ 
"upload-pack" on the
   other side.
   (merge ad6b5fefbd jv/upload-pack-filter-spec-quotefix later to maint).

 * The command line completion (in contrib/) completed "git branch -d"
   with branch names, but "git branch -D" offered tagnames in addition,
   which has been corrected.  "git branch -M" had the same problem.
   (merge 27dc071b9a jk/complete-branch-force-delete later to maint).

 * When commands are started from a subdirectory, they may have to
   compare the path to the subdirectory (called prefix and found out
   from $(pwd)) with the tracked paths.  On macOS, $(pwd) and
   readdir() yield decomposed path, while the tracked paths are
   usually normalized to the precomposed form, causing mismatch.  This
   has been fixed by taking the same approach used to normalize the
   command line arguments.
   (merge 5c327502db tb/precompose-prefix-too later to maint).

 * Even though invocations of "die()" were logged to the trace2
   system, "BUG()"s were not, which has been corrected.
   (merge 0a9dde4a04 jt/trace2-BUG later to maint).

 * "git grep --untracked" is meant to be "let's ALSO find in these
   files on the filesystem" when looking for matches in the working
   tree files, and does not make any sense if the primary search is
   done against the index, or the tree objects.  The "--cached" and
   "--untracked" options have been marked as mutually incompatible.
   (merge 0c5d83b248 mt/grep-cached-untracked later to maint).

 * Fix "git fsck --name-objects" which apparently has not been used by
   anybody who is motivated enough to report breakage.
   (merge e89f89361c js/fsck-name-objects-fix later to maint).

 * Avoid individual tests in t5411 from getting affected by each other
   by forcing them to use separate output files during the test.
   (merge 822ee894f6 jx/t5411-unique-filenames later to maint).

 * Test to make sure "git rev-parse one-thing one-thing" gives
   the same thing twice (when one-thing is --since=X).
   (merge a5cdca4520 ew/rev-parse-since-test later to maint).

 * When certain features (e.g. grafts) used in the repository are
   incompatible with the use of the commit-graph, we used to silently
   turned commit-graph off; we now tell the user what we are doing.
   (merge c85eec7fc3 js/commit-graph-warning later to maint).

 * Objects that lost references can be pruned away, even when they
   have notes attached to it (and these notes will become dangling,
   which in turn can be pruned with "git notes prune").  This has been
   clarified in the documentation.
   (merge fa9ab027ba mz/doc-notes-are-not-anchors later to maint).

 * The error codepath around the "--temp/--prefix" feature of "git
   checkout-index" has been improved.
   (merge 3f7ba60350 mt/checkout-index-corner-cases later to maint).

 * The "git maintenance register" command had trouble registering bare
   repositories, which had been corrected.

 * A handful of multi-word configuration variable names in
   documentation that are spelled in all lowercase have been corrected
   to use the more canonical camelCase.
   (merge 7dd0eaa39c dl/doc-config-camelcase later to maint).

 * "git push $there --delete ''" should have been diagnosed as an
   error, but instead turned into a matching push, which has been
   (merge 20e416409f jc/push-delete-nothing later to maint).

 * Test script modernization.
   (merge 488acf15df sv/t7001-modernize later to maint).

 * An under-allocation for the untracked cache data has been corrected.
   (merge 6347d649bc jh/untracked-cache-fix later to maint).

 * Other code cleanup, docfix, build fix, etc.
