git: updated to 2.44.0

Git v2.44 Release Notes
=======================

Backward Compatibility Notes

 * "git checkout -B <branch>" used to allow switching to a \ 
branch that
   is in use on another worktree, but this was by mistake.  The users
   need to use "--ignore-other-worktrees" option.

UI, Workflows & Features

 * "git add" and "git stash" learned to support the \ 
":(attr:...)"
   magic pathspec.

 * "git rebase --autosquash" is now enabled for non-interactive rebase,
   but it is still incompatible with the apply backend.

 * Introduce "git replay", a tool meant on the server side without
   working tree to recreate a history.

 * "git merge-file" learned to take the "--diff-algorithm" \ 
option to
   use algorithm different from the default "myers" diff.

 * Command line completion (in contrib/) learned to complete path
   arguments to the "add/set" subcommands of "git \ 
sparse-checkout"
   better.

 * "git checkout -B <branch> [<start-point>]" allowed a \ 
branch that is
   in use in another worktree to be updated and checked out, which
   might be a bit unexpected.  The rule has been tightened, which is a
   breaking change.  "--ignore-other-worktrees" option is required to
   unbreak you, if you are used to the current behaviour that "-B"
   overrides the safety.

 * The builtin_objectmode attribute is populated for each path
   without adding anything in .gitattributes files, which would be
   useful in magic pathspec, e.g., ":(attr:builtin_objectmode=100755)"
   to limit to executables.

 * "git fetch" learned to pay attention to "fetch.all" \ 
configuration
   variable, which pretends as if "--all" was passed from the command
   line when no remote parameter was given.

 * In addition to (rather cryptic) Security Identifiers, show username
   and domain in the error message when we barf on mismatch between
   the Git directory and the current user on Windows.

 * The error message given when "git branch -d branch" fails due to
   commits unique to the branch has been split into an error and a new
   conditional advice message.

 * When given an existing but unreadable file as a configuration file,
   gitweb behaved as if the file did not exist at all, but now it
   errors out.  This is a change that may break backward compatibility.

 * When $HOME/.gitconfig is missing but XDG config file is available, we
   should write into the latter, not former.  "git gc" and "git
   maintenance" wrote into a wrong "global config" file, which have
   been corrected.

 * Define "special ref" as a very narrow set that consists of
   FETCH_HEAD and MERGE_HEAD, and clarify everything else that used to
   be classified as such are actually just pseudorefs.

 * All conditional "advice" messages show how to turn them off, which
   becomes repetitive.  Setting advice.* configuration explicitly on
   now omits the instruction part.

 * The "disable repository discovery of a bare repository" check,
   triggered by setting safe.bareRepository configuration variable to
   'explicit', has been loosened to exclude the ".git/" directory inside
   a non-bare repository from the check.  So you can do "cd .git &&
   git cmd" to run a Git command that works on a bare repository without
   explicitly specifying $GIT_DIR now.

 * The completion script (in contrib/) learned more options that can
   be used with "git log".

 * The labels on conflict markers for the common ancestor, our version,
   and the other version are available to custom 3-way merge driver
   via %S, %X, and %Y placeholders.

 * The write codepath for the reftable data learned to honor
   core.fsync configuration.

 * The "--fsck-objects" option of "git index-pack" now can \ 
take the
   optional parameter to tweak severity of different fsck errors.

 * The wincred credential backend has been taught to support oauth
   refresh token the same way as credential-cache and
   credential-libsecret backends.

 * Command line completion support (in contrib/) has been
   updated for "git bisect".

 * "git branch" and friends learned to use the formatted text as
   sorting key, not the underlying timestamp value, when the --sort
   option is used with author or committer timestamp with a format
   specifier (e.g., "--sort=creatordate:format:%H:%M:%S").

 * The command line completion script (in contrib/) learned to
   complete configuration variable names better.

Performance, Internal Implementation, Development Support etc.

 * Process to add some form of low-level unit tests has started.

 * Add support for GitLab CI.

 * "git for-each-ref --no-sort" still sorted the refs alphabetically
   which paid non-trivial cost.  It has been redefined to show output
   in an unspecified order, to allow certain optimizations to take
   advantage of.

 * Simplify API implementation to delete references by eliminating
   duplication.

 * Subject approxidate() and show_date() machinery to OSS-Fuzz.

 * A new helper to let us pretend that we called lstat() when we know
   our cache_entry is up-to-date via fsmonitor.

 * The optimization based on fsmonitor in the "diff --cached"
   codepath is resurrected with the "fake-lstat" introduced earlier.

 * Test balloon to use C99 "bool" type from <stdbool.h> has been
   added.

 * "git clone" has been prepared to allow cloning a repository with
   non-default hash function into a repository that uses the reftable
   backend.

 * Streaming spans of packfile data used to be done only from a
   single, primary, pack in a repository with multiple packfiles.  It
   has been extended to allow reuse from other packfiles, too.

 * Comment updates to help developers not to attempt to modify
   messages from plumbing commands that must stay constant.

   It might make sense to reassess the plumbing needs every few years,
   but that should be done as a separate effort.

 * Move test-ctype helper to the unit-test framework.

 * Instead of manually creating refs/ hierarchy on disk upon a
   creation of a secondary worktree, which is only usable via the
   files backend, use the refs API to populate it.

 * CI for GitLab learned to drive macOS jobs.

 * A few tests to "git commit -o <pathspec>" and "git commit -i
   <pathspec>" has been added.

 * Tests on ref API are moved around to prepare for reftable.

 * The Makefile often had to say "-L$(path) -R$(path)" that repeats
   the path to the same library directory for link time and runtime.
   A Makefile template is used to reduce such repetition.

 * The priority queue test has been migrated to the unit testing
   framework.

 * Setting `feature.experimental` opts the user into multi-pack reuse
   experiment

 * Squelch node.js 16 deprecation warnings from GitHub Actions CI
   by updating actions/github-script and actions/checkout that use
   node.js 20.

 * The mechanism to report the filename in the source code, used by
   the unit-test machinery, assumed that the compiler expanded __FILE__
   to the path to the source given to the $(CC), but some compilers
   give full path, breaking the output.  This has been corrected.

Fixes since v2.43
-----------------

 * The way CI testing used "prove" could lead to running the test
   suite twice needlessly, which has been corrected.

 * Update ref-related tests.

 * "git format-patch --encode-email-headers" ignored the option when
   preparing the cover letter, which has been corrected.

 * Newer versions of Getopt::Long started giving warnings against our
   (ab)use of it in "git send-email".  Bump the minimum version
   requirement for Perl to 5.8.1 (from September 2002) to allow
   simplifying our implementation.

 * Earlier we stopped relying on commit-graph that (still) records
   information about commits that are lost from the object store,
   which has negative performance implications.  The default has been
   flipped to disable this pessimization.

 * Stale URLs have been updated to their current counterparts (or
   archive.org) and HTTP links are replaced with working HTTPS links.

 * trace2 streams used to record the URLs that potentially embed
   authentication material, which has been corrected.

 * The sample pre-commit hook that tries to catch introduction of new
   paths that use potentially non-portable characters did not notice
   an existing path getting renamed to such a problematic path, when
   rename detection was enabled.

 * The command line parser for the "log" family of commands was too
   loose when parsing certain numbers, e.g., silently ignoring the
   extra 'q' in "git log -n 1q" without complaining, which has been
   tightened up.

 * "git $cmd --end-of-options --rev -- --path" for some $cmd failed
   to interpret "--rev" as a rev, and "--path" as a path.  \ 
This was
   fixed for many programs like "reset" and "checkout".

 * "git bisect reset" has been taught to clean up state files and refs
   even when BISECT_START file is gone.

 * Some codepaths did not correctly parse configuration variables
   specified with valueless "true", which has been corrected.

 * Code clean-up for sanity checking of command line options for "git
   show-ref".

 * The code to parse the From e-mail header has been updated to avoid
   recursion.

 * "git fetch --atomic" issued an unnecessary empty error message,
   which has been corrected.

 * Command line completion script (in contrib/) learned to work better
   with the reftable backend.

 * "git status" is taught to show both the branch being bisected and
   being rebased when both are in effect at the same time.

 * "git archive --list extra garbage" silently ignored excess command
   line parameters, which has been corrected.

 * "git sparse-checkout set" added default patterns even when the
   patterns are being fed from the standard input, which has been
   corrected.

 * "git sparse-checkout (add|set) --[no-]cone --end-of-options" did
   not handle "--end-of-options" correctly after a recent update.

 * Unlike other environment variables that took the usual
   true/false/yes/no as well as 0/1, GIT_FLUSH only understood 0/1,
   which has been corrected.

 * Clearing in-core repository (happens during e.g., "git fetch
   --recurse-submodules" with commit graph enabled) made in-core
   commit object in an inconsistent state by discarding the necessary
   data from commit-graph too early, which has been corrected.

 * Update to a new feature recently added, "git show-ref --exists".

 * oss-fuzz tests are built and run in CI.
   (merge c4a9cf1df3 js/oss-fuzz-build-in-ci later to maint).

 * Rename detection logic ignored the final line of a file if it is an
   incomplete line.

 * GitHub CI update.
   (merge 0188b2c8e0 pb/ci-github-skip-logs-for-broken-tests later to maint).

 * "git diff --no-rename A B" did not disable rename detection but did
   not trigger an error from the command line parser.

 * "git archive --remote=<remote>" learned to talk over the smart
   http (aka stateless) transport.
   (merge 176cd68634 jx/remote-archive-over-smart-http later to maint).

 * Fetching via protocol v0 over Smart HTTP transport sometimes failed
   to correctly auto-follow tags.
   (merge fba732c462 jk/fetch-auto-tag-following-fix later to maint).

 * The documentation for the --exclude-per-directory option marked it
   as deprecated, which confused readers into thinking there may be a
   plan to remove it in the future, which was not our intention.
   (merge 0009542cab jc/ls-files-doc-update later to maint).

 * "git diff --no-index file1 file2" segfaulted while invoking the
   external diff driver, which has been corrected.

 * Rewrite //-comments to /* comments */ in files whose comments
   prevalently use the latter.

 * Cirrus CI jobs started breaking because we specified version of
   FreeBSD that is no longer available, which has been corrected.
   (merge 81fffb66d3 cb/use-freebsd-13-2-at-cirrus-ci later to maint).

 * A caller called index_file_exists() that takes a string expressed
   as <ptr, length> with a wrong length, which has been corrected.
   (merge 156e28b36d jh/sparse-index-expand-to-path-fix later to maint).

 * A failed "git tag -s" did not necessarily result in an error
   depending on the crypto backend, which has been corrected.

 * "git stash" sometimes was silent even when it failed due to
   unwritable index file, which has been corrected.

 * "git show-ref --verify" did not show things like \ 
"CHERRY_PICK_HEAD",
   which has been corrected.

 * Recent conversion to allow more than 0/1 in GIT_FLUSH broke the
   mechanism by flipping what yes/no means by mistake, which has been
   corrected.

 * The sequencer machinery does not use the ref API and instead
   records names of certain objects it needs for its correct operation
   in temporary files, which makes these objects susceptible to loss
   by garbage collection.  These temporary files have been added as
   starting points for reachability analysis to fix this.
   (merge bc7f5db896 pw/gc-during-rebase later to maint).

 * "git cherry-pick" invoked during "git rebase -i" session lost
   the authorship information, which has been corrected.
   (merge e4301f73ff vn/rebase-with-cherry-pick-authorship later to maint).

 * The code paths that call repo_read_object_file() have been
   tightened to react to errors.
   (merge 568459bf5e js/check-null-from-read-object-file later to maint).

 * Other code cleanup, docfix, build fix, etc.
   (merge 5aea3955bc rj/clarify-branch-doc-m later to maint).
   (merge 9cce3be2df bk/bisect-doc-fix later to maint).

git: updated to 2.38.0

Git v2.38 Release Notes
=======================

UI, Workflows & Features

 * "git remote show [-n] frotz" now pays attention to negative
   pathspec.

 * "git push" sometimes performs poorly when reachability bitmaps are
   used, even in a repository where other operations are helped by
   bitmaps.  The push.useBitmaps configuration variable is introduced
   to allow disabling use of reachability bitmaps only for "git push".

 * "git grep -m<max-hits>" is a way to limit the hits shown per file.

 * "git merge-tree" learned a new mode where it takes two commits and
   computes a tree that would result in the merge commit, if the
   histories leading to these two commits were to be merged.

 * "git mv A B" in a sparsely populated working tree can be asked to
   move a path between directories that are "in cone" (i.e. expected
   to be materialized in the working tree) and "out of cone"
   (i.e. expected to be hidden).  The handling of such cases has been
   improved.

 * Earlier, HTTP transport clients learned to tell the server side
   what locale they are in by sending Accept-Language HTTP header, but
   this was done only for some requests but not others.

 * Introduce a safe.barerepository configuration variable that
   allows users to forbid discovery of bare repositories.

 * Various messages that come from the pack-bitmap codepaths have been
   tweaked.

 * "git rebase -i" learns to update branches whose tip appear in the
   rebased range with "--update-refs" option.

 * "git ls-files" learns the "--format" option to tweak its \ 
output.

 * "git cat-file" learned an option to use the mailmap when showing
   commit and tag objects.

 * When "git merge" finds that it cannot perform a merge, it should
   restore the working tree to the state before the command was
   initiated, but in some corner cases it didn't.

 * Operating modes like "--batch" of "git cat-file" command \ 
learned to
   take NUL-terminated input, instead of one-item-per-line.

 * "git rm" has become more aware of the sparse-index feature.

 * "git rev-list --disk-usage" learned to take an optional value
   "human" to show the reported value in human-readable format, like
   "3.40MiB".

 * The "diagnose" feature to create a zip archive for diagnostic
   material has been lifted from "scalar" and made into a feature of
   "git bugreport".

 * The namespaces used by "log --decorate" from "refs/" \ 
hierarchy by
   default has been tightened.

 * "git rev-list --ancestry-path=C A..B" is a natural extension of
   "git rev-list A..B"; instead of choosing a subset of A..B to those
   that have ancestry relationship with A, it lets a subset with
   ancestry relationship with C.

 * "scalar" now enables built-in fsmonitor on enlisted repositories,
   when able.

 * The bash prompt (in contrib/) learned to optionally indicate when
   the index is unmerged.

 * "git clone" command learned the "--bundle-uri" option to \ 
coordinate
   with hosting sites the use of pre-prepared bundle files.

 * "git range-diff" learned to honor pathspec argument if given.

 * "git format-patch --from=<ident>" can be told to add an in-body
   "From:" line even for commits that are authored by the given
   <ident> with "--force-in-body-from" option.

 * The built-in fsmonitor refuses to work on a network mounted
   repositories; a configuration knob for users to override this has
   been introduced.

 * The "scalar" addition from Microsoft is now part of the core Git
   installation.

Performance, Internal Implementation, Development Support etc.

 * Collection of what is referenced by objects in promisor packs have
   been optimized to inspect these objects in the in-pack order.

 * Introduce a helper to see if a branch is already being worked on
   (hence should not be newly checked out in a working tree), which
   performs much better than the existing find_shared_symref() to
   replace many uses of the latter.

 * Teach "git archive" to (optionally and then by default) avoid
   spawning an external "gzip" process when creating \ 
".tar.gz" (and
   ".tgz") archives.

 * Allow large objects read from a packstream to be streamed into a
   loose object file straight, without having to keep it in-core as a
   whole.

 * Further preparation to turn git-submodule.sh into a builtin
   continues.

 * Apply Coccinelle rule to turn raw memmove() into MOVE_ARRAY() cpp
   macro, which would improve maintainability and readability.

 * Teach "make all" to build gitweb as well.

 * Tweak tests so that they still work when the "git init" template
   did not create .git/info directory.

 * Add Coccinelle rules to detect the pattern of initializing and then
   finalizing a structure without using it in between at all, which
   happens after code restructuring and the compilers fail to
   recognize as an unused variable.

 * The code to convert between GPG trust level strings and internal
   constants we use to represent them have been cleaned up.

 * Support for libnettle as SHA256 implementation has been added.

 * The way "git multi-pack" uses parse-options API has been improved.

 * A Coccinelle rule (in contrib/) to encourage use of COPY_ARRAY
   macro has been improved.

 * API tweak to make it easier to run fuzz testing on commit-graph parser.

 * Omit fsync-related trace2 entries when their values are all zero.

 * The codepath to write multi-pack index has been taught to release a
   large chunk of memory that holds an array of objects in the packs,
   as soon as it is done with the array, to reduce memory consumption.

 * Add a level of redirection to array allocation API in xdiff part,
   to make it easier to share with the libgit2 project.

 * "git fetch" client logs the partial clone filter used in the trace2
   output.

 * The "bundle URI" design gets documented.

 * The common ancestor negotiation exchange during a "git fetch"
   session now leaves trace log.

 * Test portability improvements.
   (merge 4d1d843be7 mt/rot13-in-c later to maint).

 * The "subcommand" mode is introduced to parse-options API and update
   the command line parser of Git commands with subcommands.

 * The pack bitmap file gained a bitmap-lookup table to speed up
   locating the necessary bitmap for a given commit.

 * The assembly version of SHA-1 implementation for PPC has been
   removed.

 * The server side that responds to "git fetch" and "git clone"
   request has been optimized by allowing it to send objects in its
   object store without recomputing and validating the object names.

 * Annotate function parameters that are not used (but cannot be
   removed for structural reasons), to prepare us to later compile
   with -Wunused warning turned on.

 * Share the text used to explain configuration variables used by "git
   <subcmd>" in "git help <subcmd>" with the text \ 
from "git help config".

 * "git mv A B" in a sparsely populated working tree can be asked to
   move a path from a directory that is "in cone" to another directory
   that is "out of cone".  Handling of such a case has been improved.

 * The chainlint script for our tests has been revamped.

Fixes since v2.37
-----------------

 * Rewrite of "git add -i" in C that appeared in Git 2.25 didn't
   correctly record a removed file to the index, which was fixed.

 * Certain diff options are currently ignored when combined-diff is
   shown; mark them as incompatible with the feature.

 * Adjust technical/bitmap-format to be formatted by AsciiDoc, and
   add some missing information to the documentation.

 * Fixes for tests when the source directory has unusual characters in
   its path, e.g. whitespaces, double-quotes, etc.

 * "git mktree --missing" lazily fetched objects that are missing from
   the local object store, which was totally unnecessary for the purpose
   of creating the tree object(s) from its input.

 * Give _() markings to fatal/warning/usage: labels that are shown in
   front of these messages.

 * References to commands-to-be-typed-literally in "git rebase"
   documentation mark-up have been corrected.

 * In a non-bare repository, the behavior of Git when the
   core.worktree configuration variable points at a directory that has
   a repository as its subdirectory, regressed in Git 2.27 days.

 * Recent update to vimdiff layout code has been made more robust
   against different end-user vim settings.

 * Plug various memory leaks, both in the main code and in test-tool
   commands.

 * Fixes a long-standing corner case bug around directory renames in
   the merge-ort strategy.

 * The resolve-undo information in the index was not protected against
   GC, which has been corrected.

 * A corner case bug where lazily fetching objects from a promisor
   remote resulted in infinite recursion has been corrected.

 * "git clone" from a repository with some ref whose HEAD is unborn
   did not set the HEAD in the resulting repository correctly, which
   has been corrected.

 * An earlier attempt to plug leaks placed a clean-up label to jump to
   at a bogus place, which as been corrected.

 * Variable quoting fix in the vimdiff driver of "git mergetool"

 * "git shortlog -n" relied on the underlying qsort() to be stable,
   which shouldn't have.  Fixed.

 * A fix for a regression in test framework.

 * mkstemp() emulation on Windows has been improved.

 * Add missing documentation for "include" and "includeIf" \ 
features in
   "git config" file format, which incidentally teaches the command
   line completion to include them in its offerings.

 * Avoid "white/black-list" in documentation and code comments.

 * Workaround for a compiler warning against use of die() in
   osx-keychain (in contrib/).

 * Workaround for a false positive compiler warning.

 * "git p4" working on UTF-16 files on Windows did not implement
   CRLF-to-LF conversion correctly, which has been corrected.

 * "git p4" did not handle non-ASCII client name well, which has been
   corrected.

 * "rerere-train" script (in contrib/) used to honor commit.gpgSign
   while recreating the throw-away merges.

 * "git checkout" miscounted the paths it updated, which has been
   corrected.

 * Fix for a bug that makes write-tree to fail to write out a
   non-existent index as a tree, introduced in 2.37.

 * There was a bug in the codepath to upgrade generation information
   in commit-graph from v1 to v2 format, which has been corrected.

 * Gitweb had legacy URL shortener that is specific to the way
   projects hosted on kernel.org used to (but no longer) work, which
   has been removed.

 * Fix build procedure for Windows that uses CMake so that it can pick
   up the shell interpreter from local installation location.

 * Conditionally allow building Python interpreter on Windows

 * Fix to lstat() emulation on Windows.

 * Older gcc with -Wall complains about the universal zero initializer
   "struct s = { 0 };" idiom, which makes developers' lives
   inconvenient (as -Werror is enabled by DEVELOPER=YesPlease).  The
   build procedure has been tweaked to help these compilers.

 * Plug memory leaks in the failure code path in the "merge-ort" merge
   strategy backend.

 * "git symbolic-ref symref non..sen..se" is now diagnosed as an error.

 * A follow-up fix to a fix for a regression in 2.36 around hooks.

 * Avoid repeatedly running getconf to ask libc version in the test
   suite, and instead just as it once per script.

 * Platform-specific code that determines if a directory is OK to use
   as a repository has been taught to report more details, especially
   on Windows.

 * "vimdiff3" regression fix.

 * "git fsck" reads mode from tree objects but canonicalizes the mode
   before passing it to the logic to check object sanity, which has
   hid broken tree objects from the checking logic.  This has been
   corrected, but to help existing projects with broken tree objects
   that they cannot fix retroactively, the severity of anomalies this
   code detects has been demoted to "info" for now.

 * Fixes to sparse index compatibility work for "reset" and \ 
"checkout"
   commands.

 * An earlier optimization discarded a tree-object buffer that is
   still in use, which has been corrected.

 * Fix deadlocks between main Git process and subprocess spawned via
   the pipe_command() API, that can kill "git add -p" that was
   reimplemented in C recently.

 * The sequencer machinery translated messages left in the reflog by
   mistake, which has been corrected.

 * xcalloc(), imitating calloc(), takes "number of elements of the
   array", and "size of a single element", in this order.  A call that
   does not follow this ordering has been corrected.

 * The preload-index codepath made copies of pathspec to give to
   multiple threads, which were left leaked.

 * Update the version of Ubuntu used for GitHub Actions CI from 18.04
   to 22.04.

 * The auto-stashed local changes created by "git merge --autostash"
   was mixed into a conflicted state left in the working tree, which
   has been corrected.

 * Multi-pack index got corrupted when preferred pack changed from one
   pack to another in a certain way, which has been corrected.
   (merge 99e4d084ff tb/midx-with-changing-preferred-pack-fix later to maint).

 * The clean-up of temporary files created via mks_tempfile_dt() was
   racy and attempted to unlink() the leading directory when signals
   are involved, which has been corrected.
   (merge babe2e0559 rs/tempfile-cleanup-race-fix later to maint).

 * FreeBSD portability fix for "git maintenance" that spawns \ 
"crontab"
   to schedule tasks.
   (merge ee69e7884e bc/gc-crontab-fix later to maint).

 * Those who use diff-so-fancy as the diff-filter noticed a regression
   or two in the code that parses the diff output in the built-in
   version of "add -p", which has been corrected.
   (merge 0a101676e5 js/add-p-diff-parsing-fix later to maint).

 * Segfault fix-up to an earlier fix to the topic to teach "git reset"
   and "git checkout" work better in a sparse checkout.
   (merge 037f8ea6d9 vd/sparse-reset-checkout-fixes later to maint).

 * "git diff --no-index A B" managed its the pathnames of its two
   input files rather haphazardly, sometimes leaking them.  The
   command line argument processing has been straightened out to clean
   it up.
   (merge 2b43dd0eb5 rs/diff-no-index-cleanup later to maint).

 * "git rev-list --verify-objects" ought to inspect the contents of
   objects and notice corrupted ones, but it didn't when the commit
   graph is in use, which has been corrected.
   (merge b27ccae34b jk/rev-list-verify-objects-fix later to maint).

 * More fixes to "add -p"
   (merge 64ec8efb83 js/builtin-add-p-portability-fix later to maint).

 * The parser in the script interface to parse-options in "git
   rev-parse" has been updated to diagnose a bogus input correctly.
   (merge f20b9c36d0 ow/rev-parse-parseopt-fix later to maint).

 * The code that manages list-object-filter structure, used in partial
   clones, leaked the instances, which has been plugged.
   (merge 66eede4a37 jk/plug-list-object-filter-leaks later to maint).

 * Fix another UI regression in the reimplemented "add -p".
   (merge f6f0ee247f rs/add-p-worktree-mode-prompt-fix later to maint).

 * "git fetch" over protocol v2 sent an incorrect ref prefix request
   to the server and made "git pull" with configured fetch refspec
   that does not cover the remote branch to merge with fail, which has
   been corrected.
   (merge 49ca2fba39 jk/proto-v2-ref-prefix-fix later to maint).

 * A result from opendir() was leaking in the commit-graph expiration
   codepath, which has been plugged.

Log message:
git: updated to 2.37.0

Git v2.37 Release Notes
=======================

UI, Workflows & Features

 * "vimdiff[123]" mergetool drivers have been reimplemented with a
   more generic layout mechanism.

 * "git -v" and "git -h" are now understood as "git \ 
--version" and
   "git --help".

 * The temporary files fed to external diff command are now generated
   inside a new temporary directory under the same basename.

 * "git log --since=X" will stop traversal upon seeing a commit that
   is older than X, but there may be commits behind it that is younger
   than X when the commit was created with a faulty clock.  A new
   option is added to keep digging without stopping, and instead
   filter out commits with timestamp older than X.

 * "git -c branch.autosetupmerge=simple branch $A $B" will set the $B
   as $A's upstream only when $A and $B shares the same name, and "git
   -c push.default=simple" on branch $A would push to update the
   branch $A at the remote $B came from.  Also more places use the
   sole remote, if exists, before defaulting to 'origin'.

 * A new doc has been added that lists tips for tools to work with
   Git's codebase.

 * "git remote -v" now shows the list-objects-filter used during
   fetching from the remote, if available.

 * With the new http.curloptResolve configuration, the CURLOPT_RESOLVE
   mechanism that allows cURL based applications to use pre-resolved
   IP addresses for the requests is exposed to the scripts.

 * "git add -i" was rewritten in C some time ago and has been in
   testing; the reimplementation is now exposed to general public by
   default.

 * Deprecate non-cone mode of the sparse-checkout feature.

 * Introduce a filesystem-dependent mechanism to optimize the way the
   bits for many loose object files are ensured to hit the disk
   platter.

 * The "do not remove the directory the user started Git in" logic,
   when Git cannot tell where that directory is, is disabled.  Earlier
   we refused to run in such a case.

 * A mechanism to pack unreachable objects into a "cruft pack",
   instead of ejecting them into loose form to be reclaimed later, has
   been introduced.

 * Update the doctype written in gitweb output to xhtml5.

 * The "transfer.credentialsInURL" configuration variable controls what
   happens when a URL with embedded login credential is used on either
   "fetch" or "push". Credentials are currently only detected in
   `remote.<name>.url` config, not `remote.<name>.pushurl`.

 * "git revert" learns "--reference" option to use more \ 
human-readable
   reference to the commit it reverts in the message template it
   prepares for the user.

 * Various error messages that talk about the removal of
   "--preserve-merges" in "rebase" have been strengthened, \ 
and "rebase
   --abort" learned to get out of a state that was left by an earlier
   use of the option.

Performance, Internal Implementation, Development Support etc.

 * The performance of the "untracked cache" feature has been improved
   when "--untracked-files=<mode>" and \ 
"status.showUntrackedFiles"
   are combined.

 * "git stash" works better with sparse index entries.

 * "git show :<path>" learned to work better with the sparse-index
   feature.

 * Introduce and apply coccinelle rule to discourage an explicit
   comparison between a pointer and NULL, and applies the clean-up to
   the maintenance track.

 * Preliminary code refactoring around transport and bundle code.

 * "sparse-checkout" learns to work better with the sparse-index
   feature.

 * A workflow change for translators are being proposed.  git.pot is
   no longer version controlled and it is local responsibility of
   translators to generate it.

 * Plug the memory leaks from the trickiest API of all, the revision
   walker.

 * Rename .env_array member to .env in the child_process structure.

  * The fsmonitor--daemon handles even more corner cases when
    watching filesystem events.

 * A new bug() and BUG_if_bug() API is introduced to make it easier to
   uniformly log "detect multiple bugs and abort in the end" pattern.

Fixes since v2.36
-----------------

 * "git submodule update" without pathspec should silently skip an
   uninitialized submodule, but it started to become noisy by mistake.
   (merge 4f1ccef87c gc/submodule-update-part2 later to maint).

 * "diff-tree --stdin" has been broken for about a year, but 2.36
   release broke it even worse by breaking running the command with
   <pathspec>, which in turn broke "gitk" and got noticed.  This has
   been corrected by aligning its behaviour to that of "log".
   (merge f8781bfda3 jc/diff-tree-stdin-fix later to maint).

 * Regression fix for 2.36 where "git name-rev" started to sometimes
   reference strings after they are freed.
   (merge 45a14f578e rs/name-rev-fix-free-after-use later to maint).

 * "git show <commit1> <commit2>... -- <pathspec>" \ 
lost the pathspec
   when showing the second and subsequent commits, which has been
   corrected.
   (merge 5cdb38458e jc/show-pathspec-fix later to maint).

 * "git fast-export -- <pathspec>" lost the pathspec when showing the
   second and subsequent commits, which has been corrected.
   (merge d1c25272f5 rs/fast-export-pathspec-fix later to maint).

 * "git format-patch <args> -- <pathspec>" lost the \ 
pathspec when
   showing the second and subsequent commits, which has been
   corrected.
   (merge 91f8f7e46f rs/format-patch-pathspec-fix later to maint).

 * "git clone --origin X" leaked piece of memory that held value read
   from the clone.defaultRemoteName configuration variable, which has
   been plugged.
   (merge 6dfadc8981 jc/clone-remote-name-leak-fix later to maint).

 * Get rid of a bogus and over-eager coccinelle rule.
   (merge 08bdd3a185 jc/cocci-xstrdup-or-null-fix later to maint).

 * The path taken by "git multi-pack-index" command from the end user
   was compared with path internally prepared by the tool without first
   normalizing, which lead to duplicated paths not being noticed,
   which has been corrected.
   (merge 11f9e8de3d ds/midx-normalize-pathname-before-comparison later to maint).

 * Correct choices of C compilers used in various CI jobs.
   (merge 3506cae04f ab/cc-package-fixes later to maint).

 * Various cleanups to "git p4".
   (merge 4ff0108d9e jh/p4-various-fixups later to maint).

 * The progress meter of "git blame" was showing incorrect numbers
   when processing only parts of the file.
   (merge e5f5d7d42e ea/progress-partial-blame later to maint).

 * "git rebase --keep-base <upstream> <branch-to-rebase>" \ 
computed the
   commit to rebase onto incorrectly, which has been corrected.
   (merge 9e5ebe9668 ah/rebase-keep-base-fix later to maint).

 * Fix a leak of FILE * in an error codepath.
   (merge c0befa0c03 kt/commit-graph-plug-fp-leak-on-error later to maint).

 * Avoid problems from interaction between malloc_check and address
   sanitizer.
   (merge 067109a5e7 pw/test-malloc-with-sanitize-address later to maint).

 * The commit summary shown after making a commit is matched to what
   is given in "git status" not to use the break-rewrite heuristics.
   (merge 84792322ed rs/commit-summary-wo-break-rewrite later to maint).

 * Update a few end-user facing messages around EOL conversion.
   (merge c970d30c2c ah/convert-warning-message later to maint).

 * Trace2 documentation updates.
   (merge a6c80c313c js/trace2-doc-fixes later to maint).

 * Build procedure fixup.
   (merge 1fbfd96f50 mg/detect-compiler-in-c-locale later to maint).

 * "git pull" without "--recurse-submodules=<arg>" made
   submodule.recurse take precedence over fetch.recurseSubmodules by
   mistake, which has been corrected.
   (merge 5819417365 gc/pull-recurse-submodules later to maint).

 * "git bisect" was too silent before it is ready to start computing
   the actual bisection, which has been corrected.
   (merge f11046e6de cd/bisect-messages-from-pre-flight-states later to maint).

 * macOS CI jobs have been occasionally flaky due to tentative version
   skew between perforce and the homebrew packager.  Instead of
   failing the whole CI job, just let it skip the p4 tests when this
   happens.
   (merge f15e00b463 cb/ci-make-p4-optional later to maint).

 * A bit of test framework fixes with a few fixes to issues found by
   valgrind.
   (merge 7c898554d7 ab/valgrind-fixes later to maint).

 * "git archive --add-file=<path>" picked up the raw permission bits
   from the path and propagated to zip output in some cases, without
   normalization, which has been corrected (tar output did not have
   this issue).
   (merge 6a61661967 jc/archive-add-file-normalize-mode later to maint).

 * "make coverage-report" without first running "make \ 
coverage" did
   not produce any meaningful result, which has been corrected.
   (merge 96ddfecc5b ep/coverage-report-wants-test-to-have-run later to maint).

 * The "--current" option of "git show-branch" should have \ 
been made
   incompatible with the "--reflog" mode, but this was not enforced,
   which has been corrected.
   (merge 41c64ae0e7 jc/show-branch-g-current later to maint).

 * "git fetch" unnecessarily failed when an unexpected optional
   section appeared in the output, which has been corrected.
   (merge 7709acf7be jt/fetch-peek-optional-section later to maint).

 * The way "git fetch" without "--update-head-ok" ensures \ 
that HEAD in
   no worktree points at any ref being updated was too wasteful, which
   has been optimized a bit.
   (merge f7400da800 os/fetch-check-not-current-branch later to maint).

 * "git fetch --recurse-submodules" from multiple remotes (either from
   a remote group, or "--all") used to make one extra "git \ 
fetch" in
   the submodules, which has been corrected.
   (merge 0353c68818 jc/avoid-redundant-submodule-fetch later to maint).

 * With a recent update to refuse access to repositories of other
   people by default, "sudo make install" and "sudo git describe"
   stopped working, which has been corrected.
   (merge 6b11e3d52e cb/path-owner-check-with-sudo-plus later to maint).

 * The tests that ensured merges stop when interfering local changes
   are present did not make sure that local changes are preserved; now
   they do.
   (merge 4b317450ce jc/t6424-failing-merge-preserve-local-changes later to maint).

 * Some real problems noticed by gcc 12 have been fixed, while false
   positives have been worked around.

 * Update the version of FreeBSD image used in Cirrus CI.
   (merge c58bebd4c6 pb/use-freebsd-12.3-in-cirrus-ci later to maint).

 * The multi-pack-index code did not protect the packfile it is going
   to depend on from getting removed while in use, which has been
   corrected.
   (merge 4090511e40 tb/midx-race-in-pack-objects later to maint).

 * Teach "git repack --geometric" work better with \ 
"--keep-pack" and
   avoid corrupting the repository when packsize limit is used.
   (merge 66731ff921 tb/geom-repack-with-keep-and-max later to maint).

 * The documentation on the interaction between "--add-file" and
   "--prefix" options of "git archive" has been improved.
   (merge a75910602a rs/document-archive-prefix later to maint).

 * A git subcommand like "git add -p" spawns a separate git process
   while relaying its command line arguments.  A pathspec with only
   negative elements was mistakenly passed with an empty string, which
   has been corrected.
   (merge b02fdbc80a jc/all-negative-pathspec later to maint).

 * With a more targeted workaround in http.c in another topic, we may
   be able to lift this blanket "GCC12 dangling-pointer warning is
   broken and unsalvageable" workaround.
   (merge 419141e495 cb/buggy-gcc-12-workaround later to maint).

 * A misconfigured 'branch..remote' led to a bug in configuration
   parsing.
   (merge f1dfbd9ee0 gc/zero-length-branch-config-fix later to maint).

 * "git -c diff.submodule=log range-diff" did not show anything for
   submodules that changed in the ranges being compared, and
   "git -c diff.submodule=diff range-diff" did not work correctly.
   Fix this by including the "--submodule=short" output
   unconditionally to be compared.

 * In Git 2.36 we revamped the way how hooks are invoked.  One change
   that is end-user visible is that the output of a hook is no longer
   directly connected to the standard output of "git" that spawns the
   hook, which was noticed post release.  This is getting corrected.
   (merge a082345372 ab/hooks-regression-fix later to maint).

 * Updating the graft information invalidates the list of parents of
   in-core commit objects that used to be in the graft file.

 * "git show-ref --heads" (and "--tags") still iterated over \ 
all the
   refs only to discard refs outside the specified area, which has
   been corrected.
   (merge c0c9d35e27 tb/show-ref-optim later to maint).

 * Remove redundant copying (with index v3 and older) or possible
   over-reading beyond end of mmapped memory (with index v4) has been
   corrected.
   (merge 6d858341d2 zh/read-cache-copy-name-entry-fix later to maint).

 * Sample watchman interface hook sometimes failed to produce
   correctly formatted JSON message, which has been corrected.
   (merge 134047b500 sn/fsmonitor-missing-clock later to maint).

 * Use-after-free (with another forget-to-free) fix.
   (merge 323822c72b ab/remote-free-fix later to maint).

 * Remove a coccinelle rule that is no longer relevant.
   (merge b1299de4a1 jc/cocci-cleanup later to maint).

Log message:
git: update to 2.36.0

Git 2.36 Release Notes
======================

Updates since Git 2.35
----------------------

Backward compatibility warts

 * "git name-rev --stdin" has been deprecated and issues a warning
   when used; use "git name-rev --annotate-stdin" instead.

 * "git clone --filter=... --recurse-submodules" only makes the
   top-level a partial clone, while submodules are fully cloned.  This
   behaviour is changed to pass the same filter down to the submodules.

 * With the fixes for CVE-2022-24765 that are common with versions of
   Git 2.30.4, 2.31.3, 2.32.2, 2.33.3, 2.34.3, and 2.35.3, Git has
   been taught not to recognise repositories owned by other users, in
   order to avoid getting affected by their config files and hooks.
   You can list the path to the safe/trusted repositories that may be
   owned by others on a multi-valued configuration variable
   `safe.directory` to override this behaviour, or use '*' to declare
   that you trust anything.

Note to those who build from the source

 * Since Git 2.31, our source assumed that the compiler you use to
   build Git supports variadic macros, with an easy-to-use escape
   hatch to allow compilation without variadic macros with an request
   to report that you had to use the escape hatch to the list.
   Because we haven't heard from anybody who actually needed to use
   the escape hatch, it has been removed, making support of variadic
   macros a hard requirement.

UI, Workflows & Features

 * Assorted updates to "git cat-file", especially "-h".

 * The command line completion (in contrib/) learns to complete
   arguments to give to "git sparse-checkout" command.

 * "git log --remerge-diff" shows the difference from mechanical merge
   result and the result that is actually recorded in a merge commit.

 * "git log" and friends learned an option --exclude-first-parent-only
   to propagate UNINTERESTING bit down only along the first-parent
   chain, just like --first-parent option shows commits that lack the
   UNINTERESTING bit only along the first-parent chain.

 * The command line completion script (in contrib/) learned to
   complete all Git subcommands, including the ones that are normally
   hidden, when GIT_COMPLETION_SHOW_ALL_COMMANDS is used.

 * "git branch" learned the "--recurse-submodules" option.

 * A user can forget to make a script file executable before giving
   it to "git bisect run".  In such a case, all tests will exit with
   126 or 127 error codes, even on revisions that are marked as good.
   Try to recognize this situation and stop iteration early.

 * When "index-pack" dies due to incoming data exceeding the maximum
   allowed input size, include the value of the limit in the error
   message.

 * The error message given by "git switch HEAD~4" has been clarified
   to suggest the "--detach" option that is required.

 * In sparse-checkouts, files mis-marked as missing from the working tree
   could lead to later problems.  Such files were hard to discover, and
   harder to correct.  Automatically detecting and correcting the marking
   of such files has been added to avoid these problems.

 * "git cat-file" learns "--batch-command" mode, which is a more
   flexible interface than the existing "--batch" or \ 
"--batch-check"
   modes, to allow different kinds of inquiries made.

 * The level of verbose output from the ort backend during inner merge
   has been aligned to that of the recursive backend.

 * "git remote rename A B", depending on the number of remote-tracking
   refs involved, takes long time renaming them.  The command has been
   taught to show progress bar while making the user wait.

 * Bundle file format gets extended to allow a partial bundle,
   filtered by similar criteria you would give when making a
   partial/lazy clone.

 * A new built-in userdiff driver for kotlin has been added.

 * "git repack" learned a new configuration to disable triggering of
   age-old "update-server-info" command, which is rarely useful these
   days.

 * "git stash" does not allow subcommands it internally runs as its
   implementation detail, except for "git reset", to emit messages;
   now "git reset" part has also been squelched.

 * "git ls-tree" learns "--oid-only" option, similar to \ 
"--name-only",
   and more generalized "--format" option.

 * "git fetch --refetch" learned to fetch everything without telling
   the other side what we already have, which is useful when you
   cannot trust what you have in the local object store.

 * "git branch" gives hint when branch tracking cannot be established
   because fetch refspecs from multiple remote repositories overlap.

 * "git worktree list --porcelain" did not c-quote pathnames and lock
   reasons with unsafe bytes correctly, which is worked around by
   introducing NUL terminated output format with "-z".

Performance, Internal Implementation, Development Support etc.

 * "git apply" (ab)used the util pointer of the string-list to keep
   track of how each symbolic link needs to be handled, which has been
   simplified by using strset.

 * Fix a hand-rolled alloca() imitation that may have violated
   alignment requirement of data being sorted in compatibility
   implementation of qsort_s() and stable qsort().

 * Use the parse-options API in "git reflog" command.

 * The conditional inclusion mechanism of configuration files using
   "[includeIf <condition>]" learns to base its decision on the
   URL of the remote repository the repository interacts with.
   (merge 399b198489 jt/conditional-config-on-remote-url later to maint).

 * "git name-rev --stdin" does not behave like usual "--stdin" at
   all.  Start the process of renaming it to "--annotate-stdin".
   (merge a2585719b3 jc/name-rev-stdin later to maint).

 * "git update-index", "git checkout-index", and "git \ 
clean" are
   taught to work better with the sparse checkout feature.

 * Use an internal call to reset_head() helper function instead of
   spawning "git checkout" in "rebase", and update code \ 
paths that are
   involved in the change.

 * Messages "ort" merge backend prepares while dealing with conflicted
   paths were unnecessarily confusing since it did not differentiate
   inner merges and outer merges.

 * Small modernization of the rerere-train script (in contrib/).

 * Use designated initializers we started using in mid 2017 in more
   parts of the codebase that are relatively quiescent.

 * Improve failure case behaviour of xdiff library when memory
   allocation fails.

 * General clean-up in reftable implementation, including
   clarification of the API documentation, tightening the code to
   honor documented length limit, etc.

 * Remove the escape hatch we added when we introduced the weather
   balloon to use variadic macros unconditionally, to make it official
   that we now have a hard dependency on the feature.

 * Makefile refactoring with a bit of suffixes rule stripping to
   optimize the runtime overhead.

 * "git stash drop" is reimplemented as an internal call to
   reflog_delete() function, instead of invoking "git reflog delete"
   via run_command() API.

 * Count string_list items in size_t, not "unsigned int".

 * The single-key interactive operation used by "git add -p" has been
   made more robust.

 * Remove unneeded <meta http-equiv=content-type...> from gitweb
   output.

 * "git name-rev" learned to use the generation numbers when setting
   the lower bound of searching commits used to explain the revision,
   when available, instead of committer time.

 * Replace core.fsyncObjectFiles with two new configuration variables,
   core.fsync and core.fsyncMethod.

 * Updates to refs traditionally weren't fsync'ed, but we can
   configure using core.fsync variable to do so.

 * "git reflog" command now uses parse-options API to parse its
   command line options.

Fixes since v2.35
-----------------

 * "rebase" and "stash" in secondary worktrees are broken in
   Git 2.35.0, which has been corrected.

 * "git pull --rebase" ignored the rebase.autostash configuration
   variable when the remote history is a descendant of our history,
   which has been corrected.
   (merge 3013d98d7a pb/pull-rebase-autostash-fix later to maint).

 * "git update-index --refresh" has been taught to deal better with
   racy timestamps (just like "git status" already does).
   (merge 2ede073fd2 ms/update-index-racy later to maint).

 * Avoid tests that are run under GIT_TRACE2 set from failing
   unnecessarily.
   (merge 944d808e42 js/test-unset-trace2-parents later to maint).

 * The merge-ort misbehaved when merge.renameLimit configuration is
   set too low and failed to find all renames.
   (merge 9ae39fef7f en/merge-ort-restart-optim-fix later to maint).

 * We explain that revs come first before the pathspec among command
   line arguments, but did not spell out that dashed options come
   before other args, which has been corrected.
   (merge c11f95010c tl/doc-cli-options-first later to maint).

 * "git add -p" rewritten in C regressed hunk splitting in some cases,
   which has been corrected.
   (merge 7008ddc645 pw/add-p-hunk-split-fix later to maint).

 * "git fetch --negotiate-only" is an internal command used by "git
   push" to figure out which part of our history is missing from the
   other side.  It should never recurse into submodules even when
   fetch.recursesubmodules configuration variable is set, nor it
   should trigger "gc".  The code has been tightened up to ensure it
   only does common ancestry discovery and nothing else.
   (merge de4eaae63a gc/fetch-negotiate-only-early-return later to maint).

 * The code path that verifies signatures made with ssh were made to
   work better on a system with CRLF line endings.
   (merge caeef01ea7 fs/ssh-signing-crlf later to maint).

 * "git sparse-checkout init" failed to write into $GIT_DIR/info
   directory when the repository was created without one, which has
   been corrected to auto-create it.
   (merge 7f44842ac1 jt/sparse-checkout-leading-dir-fix later to maint).

 * Cloning from a repository that does not yet have any branches or
   tags but has other refs resulted in a "remote transport reported
   error", which has been corrected.
   (merge dccea605b6 jt/clone-not-quite-empty later to maint).

 * Mark in various places in the code that the sparse index and the
   split index features are mutually incompatible.
   (merge 451b66c533 js/sparse-vs-split-index later to maint).

 * Update the logic to compute alignment requirement for our mem-pool.
   (merge e38bcc66d8 jc/mem-pool-alignment later to maint).

 * Pick a better random number generator and use it when we prepare
   temporary filenames.
   (merge 47efda967c bc/csprng-mktemps later to maint).

 * Update the contributor-facing documents on proposed log messages.
   (merge cdba0295b0 jc/doc-log-messages later to maint).

 * When "git fetch --prune" failed to prune the refs it wanted to
   prune, the command issued error messages but exited with exit
   status 0, which has been corrected.
   (merge c9e04d905e tg/fetch-prune-exit-code-fix later to maint).

 * Problems identified by Coverity in the reftable code have been
   corrected.
   (merge 01033de49f hn/reftable-coverity-fixes later to maint).

 * A bug that made multi-pack bitmap and the object order out-of-sync,
   making the .midx data corrupt, has been fixed.
   (merge f8b60cf99b tb/midx-bitmap-corruption-fix later to maint).

 * The build procedure has been taught to notice older version of zlib
   and enable our replacement uncompress2() automatically.
   (merge 07564773c2 ab/auto-detect-zlib-compress2 later to maint).

 * Interaction between fetch.negotiationAlgorithm and
   feature.experimental configuration variables has been corrected.
   (merge 714edc620c en/fetch-negotiation-default-fix later to maint).

 * "git diff --diff-filter=aR" is now parsed correctly.
   (merge 75408ca949 js/diff-filter-negation-fix later to maint).

 * When "git subtree" wants to create a merge, it used "git \ 
merge" and
   let it be affected by end-user's "merge.ff" configuration, which
   has been corrected.
   (merge 9158a3564a tk/subtree-merge-not-ff-only later to maint).

 * Unlike "git apply", "git patch-id" did not handle patches with
   hunks that has only 1 line in either preimage or postimage, which
   has been corrected.
   (merge 757e75c81e jz/patch-id-hunk-header-parsing-fix later to maint).

 * "receive-pack" checks if it will do any ref updates (various
   conditions could reject a push) before received objects are taken
   out of the temporary directory used for quarantine purposes, so
   that a push that is known-to-fail will not leave crufts that a
   future "gc" needs to clean up.
   (merge 5407764069 cb/clear-quarantine-early-on-all-ref-update-errors later to \ 
maint).

 * When there is no object to write .bitmap file for, "git
   multi-pack-index" triggered an error, instead of just skipping,
   which has been corrected.
   (merge eb57277ba3 tb/midx-no-bitmap-for-no-objects later to maint).

 * "git cmd -h" outside a repository should error out cleanly for many
   commands, but instead it hit a BUG(), which has been corrected.
   (merge 87ad07d735 js/short-help-outside-repo-fix later to maint).

 * "working tree" and "per-worktree ref" were in glossary, but
   "worktree" itself wasn't, which has been corrected.
   (merge 2df5387ed0 jc/glossary-worktree later to maint).

 * L10n support for a few error messages.
   (merge 3d3c23b3a7 bs/forbid-i18n-of-protocol-token-in-fetch-pack later to maint).

 * Test modernization.
   (merge d4fe066e4b sy/t0001-use-path-is-helper later to maint).

 * "git log --graph --graph" used to leak a graph structure, and there
   was no way to countermand "--graph" that appear earlier on the
   command line.  A "--no-graph" option has been added and resource
   leakage has been plugged.

 * Error output given in response to an ambiguous object name has been
   improved.
   (merge 3a73c1dfaf ab/ambiguous-object-name later to maint).

 * "git sparse-checkout" wants to work with per-worktree configuration,
   but did not work well in a worktree attached to a bare repository.
   (merge 3ce1138272 ds/sparse-checkout-requires-per-worktree-config later to maint).

 * Setting core.untrackedCache to true failed to add the untracked
   cache extension to the index.

 * Workaround we have for versions of PCRE2 before their version 10.36
   were in effect only for their versions newer than 10.36 by mistake,
   which has been corrected.
   (merge 97169fc361 rs/pcre-invalid-utf8-fix-fix later to maint).

 * Document Taylor as a new member of Git PLC at SFC.  Welcome.
   (merge e8d56ca863 tb/coc-plc-update later to maint).

 * "git checkout -b branch/with/multi/level/name && git stash" only
   recorded the last level component of the branch name, which has
   been corrected.

 * Check the return value from parse_tree_indirect() to turn segfaults
   into calls to die().
   (merge 8d2eaf649a gc/parse-tree-indirect-errors later to maint).

 * Newer version of GPGSM changed its output in a backward
   incompatible way to break our code that parses its output.  It also
   added more processes our tests need to kill when cleaning up.
   Adjustments have been made to accommodate these changes.
   (merge b0b70d54c4 fs/gpgsm-update later to maint).

 * The untracked cache newly computed weren't written back to the
   on-disk index file when there is no other change to the index,
   which has been corrected.

 * "git config -h" did not describe the "--type" option \ 
correctly.
   (merge 5445124fad mf/fix-type-in-config-h later to maint).

 * The way generation number v2 in the commit-graph files are
   (not) handled has been corrected.
   (merge 6dbf4b8172 ds/commit-graph-gen-v2-fixes later to maint).

 * The method to trigger malloc check used in our tests no longer work
   with newer versions of glibc.
   (merge baedc59543 ep/test-malloc-check-with-glibc-2.34 later to maint).

 * When "git fetch --recurse-submodules" grabbed submodule commits
   that would be needed to recursively check out newly fetched commits
   in the superproject, it only paid attention to submodules that are
   in the current checkout of the superproject.  We now do so for all
   submodules that have been run "git submodule init" on.

 * "git rebase $base $non_branch_commit", when $base is an ancestor or
   the $non_branch_commit, modified the current branch, which has been
   corrected.

 * When "shallow" information is updated, we forgot to update the
   in-core equivalent, which has been corrected.

 * When creating a loose object file, we didn't report the exact
   filename of the file we failed to fsync, even though the
   information was readily available, which has been corrected.

 * "git am" can read from the standard input when no mailbox is given
   on the command line, but the end-user gets no indication when it
   happens, making Git appear stuck.
   (merge 7b20af6a06 jc/mailsplit-warn-on-tty later to maint).

 * "git mv" failed to refresh the cached stat information for the
   entry it moved.
   (merge b7f9130a06 vd/mv-refresh-stat later to maint).

Log message:
git: updated to 2.33.1

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
   corrected.

 * 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
   corrected.

 * 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
   corrected.

 * "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 \ 
corrected.

 * "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
   corrected.

 * 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
   corrected.

 * "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
   dependencies.

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

Also contains various documentation updates and code clean-ups.

Log message:
git: updated to 2.32.0

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
   corrected.

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

 * "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
   introduced.

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

 * "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,
   respectively.

 * "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
   updated.

 * "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
   handled.

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
   area.

 * 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
   timeframe.

 * 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)
   option.
   (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
   corrected.
   (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 \ 
fetch"
   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.
