Git 2.24 Release Notes
======================

Updates since v2.23
-------------------

Backward compatibility note

 * "filter-branch" is showing its age and alternatives are available.
   From this release, we started to discourage its use and hint
   people about filter-repo.

UI, Workflows & Features

 * We now have an active interim maintainer for the Git-Gui part of
   the system.  Praise and thank Pratyush Yadav for volunteering.

 * The command line parser learned "--end-of-options" notation; the
   standard convention for scripters to have hardcoded set of options
   first on the command line, and force the command to treat end-user
   input as non-options, has been to use "--" as the delimiter, but
   that would not work for commands that use "--" as a delimiter
   between revs and pathspec.

 * A mechanism to affect the default setting for a (related) group of
   configuration variables is introduced.

 * "git fetch" learned "--set-upstream" option to help those \ 
who first
   clone from their private fork they intend to push to, add the true
   upstream via "git remote add" and then "git fetch" from it.

 * Device-tree files learned their own userdiff patterns.
   (merge 3c81760bc6 sb/userdiff-dts later to maint).

 * "git rebase --rebase-merges" learned to drive different merge
   strategies and pass strategy specific options to them.

 * A new "pre-merge-commit" hook has been introduced.

 * Command line completion updates for "git -c var.name=val" have been
   added.

 * The lazy clone machinery has been taught that there can be more
   than one promisor remote and consult them in order when downloading
   missing objects on demand.

 * The list-objects-filter API (used to create a sparse/lazy clone)
   learned to take a combined filter specification.

 * The documentation and tests for "git format-patch" have been
   cleaned up.

 * On Windows, the root level of UNC share is now allowed to be used
   just like any other directory.

 * The command line completion support (in contrib/) learned about the
   "--skip" option of "git revert" and "git \ 
cherry-pick".

 * "git rebase --keep-base <upstream>" tries to find the \ 
original base
   of the topic being rebased and rebase on top of that same base,
   which is useful when running the "git rebase -i" (and its limited
   variant "git rebase -x").

   The command also has learned to fast-forward in more cases where it
   can instead of replaying to recreate identical commits.

 * A configuration variable tells "git fetch" to write the commit
   graph after finishing.

 * "git add -i" has been taught to show the total number of hunks and
   the hunks that has been processed so far when showing prompts.

 * "git fetch --jobs=<n>" allowed <n> parallel jobs when \ 
fetching
   submodules, but this did not apply to "git fetch --multiple" that
   fetches from multiple remote repositories.  It now does.

 * The installation instruction for zsh completion script (in
   contrib/) has been a bit improved.

Performance, Internal Implementation, Development Support etc.

 * The code to write commit-graph over given commit object names has
   been made a bit more robust.

 * The first line of verbose output from each test piece now carries
   the test name and number to help scanning with eyeballs.

 * Further clean-up of the initialization code.

 * xmalloc() used to have a mechanism to ditch memory and address
   space resources as the last resort upon seeing an allocation
   failure from the underlying malloc(), which made the code complex
   and thread-unsafe with dubious benefit, as major memory resource
   users already do limit their uses with various other mechanisms.
   It has been simplified away.

 * Unnecessary full-tree diff in "git log -L" machinery has been
   optimized away.

 * The http transport lacked some optimization the native transports
   learned to avoid unnecessary ref advertisement, which has been
   corrected.

 * Preparation for SHA-256 upgrade continues in the test department.
   (merge 0c37c41d13 bc/hash-independent-tests-part-5 later to maint).

 * The memory ownership model of the "git fast-import" got
   straightened out.

 * Output from trace2 subsystem is formatted more prettily now.

 * The internal code originally invented for ".gitignore" processing
   got reshuffled and renamed to make it less tied to "excluding" and
   stress more that it is about "matching", as it has been reused for
   things like sparse checkout specification that want to check if a
   path is "included".

 * "git stash" learned to write refreshed index back to disk.

 * Coccinelle checks are done on more source files than before now.

 * The cache-tree code has been taught to be less aggressive in
   attempting to see if a tree object it computed already exists in
   the repository.

 * The code to parse and use the commit-graph file has been made more
   robust against corrupted input.

 * The hg-to-git script (in contrib/) has been updated to work with
   Python 3.

 * Update the way build artifacts in t/helper/ directory are ignored.

 * Preparation for SHA-256 upgrade continues.

 * "git log --graph" for an octopus merge is sometimes colored
   incorrectly, which is demonstrated and documented but not yet
   fixed.

 * The trace2 output, when sending them to files in a designated
   directory, can populate the directory with too many files; a
   mechanism is introduced to set the maximum number of files and
   discard further logs when the maximum is reached.

 * We have adopted a Code-of-conduct document.
   (merge 3f9ef874a7 jk/coc later to maint).

Fixes since v2.23
-----------------

 * "git grep --recurse-submodules" that looks at the working tree
   files looked at the contents in the index in submodules, instead of
   files in the working tree.
   (merge 6a289d45c0 mt/grep-submodules-working-tree later to maint).

 * Codepaths to walk tree objects have been audited for integer
   overflows and hardened.
   (merge 5aa02f9868 jk/tree-walk-overflow later to maint).

 * "git pack-refs" can lose refs that are created while running, which
   is getting corrected.
   (merge a613d4f817 sc/pack-refs-deletion-racefix later to maint).

 * "git checkout" and "git restore" to re-populate the index \ 
from a
   tree-ish (typically HEAD) did not work correctly for a path that
   was removed and then added again with the intent-to-add bit, when
   the corresponding working tree file was empty.  This has been
   corrected.

 * Compilation fix.
   (merge 70597e8386 rs/nedalloc-fixlets later to maint).

 * "git gui" learned to call the clean-up procedure before exiting.
   (merge 0d88f3d2c5 py/git-gui-do-quit later to maint).

 * We promoted the "indent heuristics" that decides where to split
   diff hunks from experimental to the default a few years ago, but
   some stale documentation still marked it as experimental, which has
   been corrected.
   (merge 64e5e1fba1 sg/diff-indent-heuristic-non-experimental later to maint).

 * Fix a mismerge that happened in 2.22 timeframe.
   (merge acb7da05ac en/checkout-mismerge-fix later to maint).

 * "git archive" recorded incorrect length in extended pax header in
   some corner cases, which has been corrected.
   (merge 71d41ff651 rs/pax-extended-header-length-fix later to maint).

 * On-demand object fetching in lazy clone incorrectly tried to fetch
   commits from submodule projects, while still working in the
   superproject, which has been corrected.
   (merge a63694f523 jt/diff-lazy-fetch-submodule-fix later to maint).

 * Prepare get_short_oid() codepath to be thread-safe.
   (merge 7cfcb16b0e rs/sort-oid-array-thread-safe later to maint).

 * "for-each-ref" and friends that show refs did not protect themselves
   against ancient tags that did not record tagger names when asked to
   show "%(taggername)", which have been corrected.
   (merge 8b3f33ef11 mp/for-each-ref-missing-name-or-email later to maint).

 * The "git am" based backend of "git rebase" ignored the \ 
result of
   updating ".gitattributes" done in one step when replaying
   subsequent steps.
   (merge 2c65d90f75 bc/reread-attributes-during-rebase later to maint).

 * Tell cURL library to use the same malloc() implementation, with the
   xmalloc() wrapper, as the rest of the system, for consistency.
   (merge 93b980e58f cb/curl-use-xmalloc later to maint).

 * Build fix to adjust .gitignore to unignore a path that we started to track.
   (merge aac6ff7b5b js/visual-studio later to maint).

 * A few implementation fixes in the notes API.
   (merge 60fe477a0b mh/notes-duplicate-entries later to maint).

 * Fix an earlier regression to "git push --all" which should have
   been forbidden when the target remote repository is set to be a
   mirror.
   (merge 8e4c8af058 tg/push-all-in-mirror-forbidden later to maint).

 * Fix an earlier regression in the test suite, which mistakenly
   stopped running HTTPD tests.
   (merge 3960290675 sg/git-test-boolean later to maint).

 * "git rebase --autostash <upstream> <branch>", when \ 
<branch> is
   different from the current branch, incorrectly moved the tip of the
   current branch, which has been corrected.
   (merge bf1e28e0ad bw/rebase-autostash-keep-current-branch later to maint).

 * Update support for Asciidoctor documentation toolchain.
   (merge 83b0b8953e ma/asciidoctor-refmiscinfo later to maint).

 * Start using DocBook 5 (instead of DocBook 4.5) as Asciidoctor 2.0
   no longer works with the older one.
   (merge f6461b82b9 bc/doc-use-docbook-5 later to maint).

 * The markup used in user-manual has been updated to work better with
   asciidoctor.
   (merge c4d2f6143a ma/user-manual-markup-update later to maint).

 * Make sure the grep machinery does not abort when seeing a payload
   that is not UTF-8 even when JIT is not in use with PCRE1.
   (merge ad7c543e3b cb/skip-utf8-check-with-pcre1 later to maint).

 * The name of the blob object that stores the filter specification
   for sparse cloning/fetching was interpreted in a wrong place in the
   code, causing Git to abort.

 * "git log --decorate-refs-exclude=<pattern>" was incorrectly
   overruled when the "--simplify-by-decoration" option is used, which
   has been corrected.
   (merge 0cc7380d88 rs/simplify-by-deco-with-deco-refs-exclude later to maint).

 * The "upload-pack" (the counterpart of "git fetch") needs \ 
to disable
   commit-graph when responding to a shallow clone/fetch request, but
   the way this was done made Git panic, which has been corrected.

 * The object traversal machinery has been optimized not to load tree
   objects when we are only interested in commit history.
   (merge 72ed80c784 jk/list-objects-optim-wo-trees later to maint).

 * The object name parser for "Nth parent" syntax has been made more
   robust against integer overflows.
   (merge 59fa5f5a25 rs/nth-parent-parse later to maint).

 * The code used in following tags in "git fetch" has been optimized.
   (merge b7e2d8bca5 ms/fetch-follow-tag-optim later to maint).

 * Regression fix for progress output.
   (merge 2bb74b53a4 sg/progress-fix later to maint).

 * A bug in merge-recursive code that triggers when a branch with a
   symbolic link is merged with a branch that replaces it with a
   directory has been fixed.
   (merge 83e3ad3b12 jt/merge-recursive-symlink-is-not-a-dir-in-way later to maint).

 * The rename detection logic sorts a list of rename source candidates
   by similarity to pick the best candidate, which means that a tie
   between sources with the same similarity is broken by the original
   location in the original candidate list (which is sorted by path).
   Force the sorting by similarity done with a stable sort, which is
   not promised by system supplied qsort(3), to ensure consistent
   results across platforms.
   (merge 2049b8dc65 js/diff-rename-force-stable-sort later to maint).

 * The code to skip "UTF" and "UTF-" prefix, when computing \ 
an advice
   message, did not work correctly when the prefix was "UTF", which
   has been fixed.
   (merge b181676ce9 rs/convert-fix-utf-without-dash later to maint).

 * The author names taken from SVN repositories may have extra leading
   or trailing whitespaces, which are now munged away.
   (merge 4ddd4bddb1 tk/git-svn-trim-author-name later to maint).

 * "git rebase -i" showed a wrong HEAD while "reword" open \ 
the editor.
   (merge b0a3186140 pw/rebase-i-show-HEAD-to-reword later to maint).

 * A few simplification and bugfixes to PCRE interface.
   (merge c581e4a749 ab/pcre-jit-fixes later to maint).

 * PCRE fixes.
   (merge ff61681b46 cb/pcre1-cleanup later to maint).

 * "git range-diff" segfaulted when diff.noprefix configuration was
   used, as it blindly expected the patch it internally generates to
   have the standard a/ and b/ prefixes.  The command now forces the
   internal patch to be built without any prefix, not to be affected
   by any end-user configuration.
   (merge 937b76ed49 js/range-diff-noprefix later to maint).

 * "git stash apply" in a subdirectory of a secondary worktree failed
   to access the worktree correctly, which has been corrected.
   (merge dfd557c978 js/stash-apply-in-secondary-worktree later to maint).

 * The merge-recursive machinery is one of the most complex parts of
   the system that accumulated cruft over time.  This large series
   cleans up the implementation quite a bit.
   (merge b657047719 en/merge-recursive-cleanup later to maint).

 * Pretty-printed command line formatter (used in e.g. reporting the
   command being run by the tracing API) had a bug that lost an
   argument that is an empty string, which has been corrected.
   (merge ce2d7ed2fd gs/sq-quote-buf-pretty later to maint).

 * "git range-diff" failed to handle mode-only change, which has been
   corrected.
   (merge 2b6a9b13ca tg/range-diff-output-update later to maint).

 * Dev support update.
   (merge 4f3c1dc5d6 dl/allow-running-cocci-verbosely later to maint).

 * "git format-patch -o <outdir>" did an equivalent of \ 
"mkdir <outdir>"
   not "mkdir -p <outdir>", which was corrected.

 * "git stash save" lost local changes to submodules, which has been
   corrected.
   (merge 556895d0c8 jj/stash-reset-only-toplevel later to maint).

 * The atomic push over smart HTTP transport did not work, which has
   been corrected.
   (merge 6f1194246a bc/smart-http-atomic-push later to maint).

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

Git 2.23 Release Notes
======================

Updates since v2.22
-------------------

Backward compatibility note

 * The "--base" option of "format-patch" computed the \ 
patch-ids for
   prerequisite patches in an unstable way, which has been updated to
   compute in a way that is compatible with "git patch-id --stable".

 * The "git log" command by default behaves as if the --mailmap option
   was given.

UI, Workflows & Features

 * The "git fast-export/import" pair has been taught to handle commits
   with log messages in encoding other than UTF-8 better.

 * In recent versions of Git, per-worktree refs are exposed in
   refs/worktrees/<wtname>/ hierarchy, which means that worktree names
   must be a valid refname component.  The code now sanitizes the names
   given to worktrees, to make sure these refs are well-formed.

 * "git merge" learned "--quit" option that cleans up the \ 
in-progress
   merge while leaving the working tree and the index still in a mess.

 * "git format-patch" learns a configuration to set the default for
   its --notes=<ref> option.

 * The code to show args with potential typo that cannot be
   interpreted as a commit-ish has been improved.

 * "git clone --recurse-submodules" learned to set up the submodules
   to ignore commit object names recorded in the superproject gitlink
   and instead use the commits that happen to be at the tip of the
   remote-tracking branches from the get-go, by passing the new
   "--remote-submodules" option.

 * The pattern "git diff/grep" use to extract funcname and words
   boundary for Matlab has been extend to cover Octave, which is more
   or less equivalent.

 * "git help git" was hard to discover (well, at least for some
   people).

 * The pattern "git diff/grep" use to extract funcname and words
   boundary for Rust has been added.

 * "git status" can be told a non-standard default value for the
   "--[no-]ahead-behind" option with a new configuration variable
   status.aheadBehind.

 * "git fetch" and "git pull" reports when a fetch results in
   non-fast-forward updates to let the user notice unusual situation.
   The commands learned "--no-show-forced-updates" option to disable
   this safety feature.

 * Two new commands "git switch" and "git restore" are \ 
introduced to
   split "checking out a branch to work on advancing its history" and
   "checking out paths out of the index and/or a tree-ish to work on
   advancing the current history" out of the single "git checkout"
   command.

 * "git branch --list" learned to always output the detached HEAD as
   the first item (when the HEAD is detached, of course), regardless
   of the locale.

 * The conditional inclusion mechanism learned to base the choice on
   the branch the HEAD currently is on.

 * "git rev-list --objects" learned the "--no-object-names" \ 
option to
   squelch the path to the object that is used as a grouping hint for
   pack-objects.

 * A new tag.gpgSign configuration variable turns "git tag -a" into
   "git tag -s".

 * "git multi-pack-index" learned expire and repack subcommands.

 * "git blame" learned to "ignore" commits in the history, whose
   effects (as well as their presence) get ignored.

 * "git cherry-pick/revert" learned a new "--skip" action.

 * The tips of refs from the alternate object store can be used as
   starting point for reachability computation now.

 * Extra blank lines in "git status" output have been reduced.

 * The commits in a repository can be described by multiple
   commit-graph files now, which allows the commit-graph files to be
   updated incrementally.

 * "git range-diff" output has been tweaked for easier identification
   of which part of what file the patch shown is about.

Performance, Internal Implementation, Development Support etc.

 * Update supporting parts of "git rebase" to remove code that should
   no longer be used.

 * Developer support to emulate unsatisfied prerequisites in tests to
   ensure that the remainder of the tests still succeeds when tests
   with prerequisites are skipped.

 * "git update-server-info" learned not to rewrite the file with the
   same contents.

 * The way of specifying the path to find dynamic libraries at runtime
   has been simplified.  The old default to pass -R/path/to/dir has been
   replaced with the new default to pass -Wl,-rpath,/path/to/dir,
   which is the more recent GCC uses.  Those who need to build with an
   old GCC can still use "CC_LD_DYNPATH=-R"

 * Prepare use of reachability index in topological walker that works
   on a range (A..B).

 * A new tutorial targeting specifically aspiring git-core
   developers has been added.

 * Auto-detect how to tell HP-UX aCC where to use dynamically linked
   libraries from at runtime.

 * "git mergetool" and its tests now spawn fewer subprocesses.

 * Dev support update to help tracing out tests.

 * Support to build with MSVC has been updated.

 * "git fetch" that grabs from a group of remotes learned to run the
   auto-gc only once at the very end.

 * A handful of Windows build patches have been upstreamed.

 * The code to read state files used by the sequencer machinery for
   "git status" has been made more robust against a corrupt or stale
   state files.

 * "git for-each-ref" with multiple patterns have been optimized.

 * The tree-walk API learned to pass an in-core repository
   instance throughout more codepaths.

 * When one step in multi step cherry-pick or revert is reset or
   committed, the command line prompt script failed to notice the
   current status, which has been improved.

 * Many GIT_TEST_* environment variables control various aspects of
   how our tests are run, but a few followed "non-empty is true, empty
   or unset is false" while others followed the usual "there are a few
   ways to spell true, like yes, on, etc., and also ways to spell
   false, like no, off, etc." convention.

 * Adjust the dir-iterator API and apply it to the local clone
   optimization codepath.

 * We have been trying out a few language features outside c89; the
   coding guidelines document did not talk about them and instead had
   a blanket ban against them.

 * A test helper has been introduced to optimize preparation of test
   repositories with many simple commits, and a handful of test
   scripts have been updated to use it.

Fixes since v2.22
-----------------

 * A relative pathname given to "git init --template=<path> \ 
<repo>"
   ought to be relative to the directory "git init" gets invoked in,
   but it instead was made relative to the repository, which has been
   corrected.

 * "git worktree add" used to fail when another worktree connected to
   the same repository was corrupt, which has been corrected.

 * The ownership rule for the file descriptor to fast-import remote
   backend was mixed up, leading to an unrelated file descriptor getting
   closed, which has been fixed.

 * A "merge -c" instruction during "git rebase \ 
--rebase-merges" should
   give the user a chance to edit the log message, even when there is
   otherwise no need to create a new merge and replace the existing
   one (i.e. fast-forward instead), but did not.  Which has been
   corrected.

 * Code cleanup and futureproof.

 * More parameter validation.

 * "git update-server-info" used to leave stale packfiles in its
   output, which has been corrected.

 * The server side support for "git fetch" used to show incorrect
   value for the HEAD symbolic ref when the namespace feature is in
   use, which has been corrected.

 * "git am -i --resolved" segfaulted after trying to see a commit as
   if it were a tree, which has been corrected.

 * "git bundle verify" needs to see if prerequisite objects exist in
   the receiving repository, but the command did not check if we are
   in a repository upfront, which has been corrected.

 * "git merge --squash" is designed to update the working tree and the
   index without creating the commit, and this cannot be countermanded
   by adding the "--commit" option; the command now refuses to work
   when both options are given.

 * The data collected by fsmonitor was not properly written back to
   the on-disk index file, breaking t7519 tests occasionally, which
   has been corrected.

 * Update to Unicode 12.1 width table.

 * The command line to invoke a "git cat-file" command from inside
   "git p4" was not properly quoted to protect a caret and running a
   broken command on Windows, which has been corrected.

 * "git request-pull" learned to warn when the ref we ask them to pull
   from in the local repository and in the published repository are
   different.

 * When creating a partial clone, the object filtering criteria is
   recorded for the origin of the clone, but this incorrectly used a
   hardcoded name "origin" to name that remote; it has been corrected
   to honor the "--origin <name>" option.

 * "git fetch" into a lazy clone forgot to fetch base objects that are
   necessary to complete delta in a thin packfile, which has been
   corrected.

 * The filter_data used in the list-objects-filter (which manages a
   lazily sparse clone repository) did not use the dynamic array API
   correctly---'nr' is supposed to point at one past the last element
   of the array in use.  This has been corrected.

 * The description about slashes in gitignore patterns (used to
   indicate things like "anchored to this level only" and "only
   matches directories") has been revamped.

 * The URL decoding code has been updated to avoid going past the end
   of the string while parsing %-<hex>-<hex> sequence.

 * The list of for-each like macros used by clang-format has been
   updated.

 * "git branch --list" learned to show branches that are checked out
   in other worktrees connected to the same repository prefixed with
   '+', similar to the way the currently checked out branch is shown
   with '*' in front.
   (merge 6e9381469e nb/branch-show-other-worktrees-head later to maint).

 * Code restructuring during 2.20 period broke fetching tags via
   "import" based transports.

 * The commit-graph file is now part of the "files that the runtime
   may keep open file descriptors on, all of which would need to be
   closed when done with the object store", and the file descriptor to
   an existing commit-graph file now is closed before "gc" finalizes a
   new instance to replace it.

 * "git checkout -p" needs to selectively apply a patch in reverse,
   which did not work well.

 * Code clean-up to avoid signed integer wraparounds during binary search.

 * "git interpret-trailers" always treated '#' as the comment
   character, regardless of core.commentChar setting, which has been
   corrected.

 * "git stash show 23" used to work, but no more after getting
   rewritten in C; this regression has been corrected.

 * "git rebase --abort" used to leave refs/rewritten/ when concluding
   "git rebase -r", which has been corrected.

 * An incorrect list of options was cached after command line
   completion failed (e.g. trying to complete a command that requires
   a repository outside one), which has been corrected.

 * The code to parse scaled numbers out of configuration files has
   been made more robust and also easier to follow.

 * The codepath to compute delta islands used to spew progress output
   without giving the callers any way to squelch it, which has been
   fixed.

 * Protocol capabilities that go over wire should never be translated,
   but it was incorrectly marked for translation, which has been
   corrected.  The output of protocol capabilities for debugging has
   been tweaked a bit.

 * Use "Erase in Line" CSI sequence that is already used in the editor
   support to clear cruft in the progress output.

 * "git submodule foreach" did not protect command line options passed
   to the command to be run in each submodule correctly, when the
   "--recursive" option was in use.

 * The configuration variable rebase.rescheduleFailedExec should be
   effective only while running an interactive rebase and should not
   affect anything when running a non-interactive one, which was not
   the case.  This has been corrected.

 * The "git clone" documentation refers to command line options in its
   description in the short form; they have been replaced with long
   forms to make them more recognisable.

 * Generation of pack bitmaps are now disabled when .keep files exist,
   as these are mutually exclusive features.
   (merge 7328482253 ew/repack-with-bitmaps-by-default later to maint).

 * "git rm" to resolve a conflicted path leaked an internal message
   "needs merge" before actually removing the path, which was
   confusing.  This has been corrected.

 * "git stash --keep-index" did not work correctly on paths that have
   been removed, which has been fixed.
   (merge b932f6a5e8 tg/stash-keep-index-with-removed-paths later to maint).

 * Window 7 update ;-)

 * A codepath that reads from GPG for signed object verification read
   past the end of allocated buffer, which has been fixed.

 * "git clean" silently skipped a path when it cannot lstat() it; now
   it gives a warning.

 * "git push --atomic" that goes over the transport-helper (namely,
   the smart http transport) failed to prevent refs to be pushed when
   it can locally tell that one of the ref update will fail without
   having to consult the other end, which has been corrected.

 * The internal diff machinery can be made to read out of bounds while
   looking for --function-context line in a corner case, which has been
   corrected.
   (merge b777f3fd61 jk/xdiff-clamp-funcname-context-index later to maint).

 * Other code cleanup, docfix, build fix, etc.
   (merge fbec05c210 cc/test-oidmap later to maint).
   (merge 7a06fb038c jk/no-system-includes-in-dot-c later to maint).
   (merge 81ed2b405c cb/xdiff-no-system-includes-in-dot-c later to maint).

Changelog:
Git 2.22 Release Notes
======================

Updates since v2.21
-------------------

Backward compatibility note

 * The filter specification "--filter=sparse:path=<path>" used to
   create a lazy/partial clone has been removed.  Using a blob that is
   part of the project as sparse specification is still supported with
   the "--filter=sparse:oid=<blob>" option.

UI, Workflows & Features

 * "git checkout --no-overlay" can be used to trigger a new mode of
   checking out paths out of the tree-ish, that allows paths that
   match the pathspec that are in the current index and working tree
   and are not in the tree-ish.

 * The %(trailers) formatter in "git log --format=..."  now allows to
   optionally pick trailers selectively by keyword, show only values,
   etc.

 * Four new configuration variables {author,committer}.{name,email}
   have been introduced to override user.{name,email} in more specific
   cases.

 * Command-line completion (in contrib/) learned to tab-complete the
   "git submodule absorbgitdirs" subcommand.

 * "git branch" learned a new subcommand "--show-current".

 * Output from "diff --cc" did not show the original paths when the
   merge involved renames.  A new option adds the paths in the
   original trees to the output.

 * The command line completion (in contrib/) has been taught to
   complete more subcommand parameters.

 * The final report from "git bisect" used to show the suspected
   culprit using a raw "diff-tree", with which there is no output for
   a merge commit.  This has been updated to use a more modern and
   human readable output that still is concise enough.

 * "git rebase --rebase-merges" replaces its old \ 
"--preserve-merges"
   option; the latter is now marked as deprecated.

 * Error message given while cloning with --recurse-submodules has
   been updated.

 * The completion helper code now pays attention to repository-local
   configuration (when available), which allows --list-cmds to honour
   a repository specific setting of completion.commands, for example.

 * "git mergetool" learned to offer Sublime Merge (smerge) as one of
   its backends.

 * A new hook "post-index-change" is called when the on-disk index
   file changes, which can help e.g. a virtualized working tree
   implementation.

 * "git difftool" can now run outside a repository.

 * "git checkout -m <other>" was about carrying the differences
   between HEAD and the working-tree files forward while checking out
   another branch, and ignored the differences between HEAD and the
   index.  The command has been taught to abort when the index and the
   HEAD are different.

 * A progress indicator has been added to the "index-pack" step, which
   often makes users wait for completion during "git clone".

 * "git submodule" learns "set-branch" subcommand that allows the
   submodule.*.branch settings to be modified.

 * "git merge-recursive" backend recently learned a new heuristics to
   infer file movement based on how other files in the same directory
   moved.  As this is inherently less robust heuristics than the one
   based on the content similarity of the file itself (rather than
   based on what its neighbours are doing), it sometimes gives an
   outcome unexpected by the end users.  This has been toned down to
   leave the renamed paths in higher/conflicted stages in the index so
   that the user can examine and confirm the result.

 * "git tag" learned to give an advice suggesting it might be a
   mistake when creating an annotated or signed tag that points at
   another tag.

 * The "git pack-objects" command learned to report the number of
   objects it packed via the trace2 mechanism.

 * The list of conflicted paths shown in the editor while concluding a
   conflicted merge was shown above the scissors line when the
   clean-up mode is set to "scissors", even though it was commented
   out just like the list of updated paths and other information to
   help the user explain the merge better.

 * The trace2 tracing facility learned to auto-generate a filename
   when told to log to a directory.

 * "git clone" learned a new --server-option option when talking over
   the protocol version 2.

 * The connectivity bitmaps are created by default in bare
   repositories now; also the pathname hash-cache is created by
   default to avoid making crappy deltas when repacking.

 * "git branch new A...B" and "git checkout -b new A...B" \ 
have been
   taught that in their contexts, the notation A...B means "the merge
   base between these two commits", just like "git checkout A...B"
   detaches HEAD at that commit.

 * Update "git difftool" and "git mergetool" so that the \ 
combinations
   of {diff,merge}.{tool,guitool} configuration variables serve as
   fallback settings of each other in a sensible order.

 * The "--dir-diff" mode of "git difftool" is not useful in \ 
"--no-index"
   mode; they are now explicitly marked as mutually incompatible.

Performance, Internal Implementation, Development Support etc.

 * The diff machinery, one of the oldest parts of the system, which
   long predates the parse-options API, uses fairly long and complex
   handcrafted option parser.  This is being rewritten to use the
   parse-options API.

 * The implementation of pack-redundant has been updated for
   performance in a repository with many packfiles.

 * A more structured way to obtain execution trace has been added.

 * "git prune" has been taught to take advantage of reachability
   bitmap when able.

 * The command line parser of "git commit-tree" has been rewritten to
   use the parse-options API.

 * Suggest GitGitGadget instead of submitGit as a way to submit
   patches based on GitHub PR to us.

 * The test framework has been updated to help developers by making it
   easier to run most of the tests under different versions of
   over-the-wire protocols.

 * Dev support update to make it easier to compare two formatted
   results from our documentation.

 * The scripted "git rebase" implementation has been retired.

 * "git multi-pack-index verify" did not scale well with the number of
   packfiles, which is being improved.

 * "git stash" has been rewritten in C.

 * The "check-docs" Makefile target to support developers has been
   updated.

 * The tests have been updated not to rely on the abbreviated option
   names the parse-options API offers, to protect us from an
   abbreviated form of an option that used to be unique within the
   command getting non-unique when a new option that share the same
   prefix is added.

 * The scripted version of "git rebase -i" wrote and rewrote the todo
   list many times during a single step of its operation, and the
   recent C-rewrite made a faithful conversion of the logic to C.  The
   implementation has been updated to carry necessary information
   around in-core to avoid rewriting the same file over and over
   unnecessarily.

 * Test framework update to more robustly clean up leftover files and
   processes after tests are done.

 * Conversion from unsigned char[20] to struct object_id continues.

 * While running "git diff" in a lazy clone, we can upfront know which
   missing blobs we will need, instead of waiting for the on-demand
   machinery to discover them one by one.  The code learned to aim to
   achieve better performance by batching the request for these
   promised blobs.

 * During an initial "git clone --depth=..." partial clone, it is
   pointless to spend cycles for a large portion of the connectivity
   check that enumerates and skips promisor objects (which by
   definition is all objects fetched from the other side).  This has
   been optimized out.

 * Mechanically and systematically drop "extern" from function
   declaration.

 * The script to aggregate perf result unconditionally depended on
   libjson-perl even though it did not have to, which has been
   corrected.

 * The internal implementation of "git rebase -i" has been updated to
   avoid forking a separate "rebase--interactive" process.

 * Allow DEP and ASLR for Windows build to for security hardening.

 * Performance test framework has been broken and measured the version
   of Git that happens to be on $PATH, not the specified one to
   measure, for a while, which has been corrected.

 * Optionally "make coccicheck" can feed multiple source files to
   spatch, gaining performance while spending more memory.

 * Attempt to use an abbreviated option in "git clone --recurs" is
   responded by a request to disambiguate between --recursive and
   --recurse-submodules, which is bad because these two are synonyms.
   The parse-options API has been extended to define such synonyms
   more easily and not produce an unnecessary failure.

 * A pair of private functions in http.c that had names similar to
   fread/fwrite did not return the number of elements, which was found
   to be confusing.

 * Update collision-detecting SHA-1 code to build properly on HP-UX.

Fixes since v2.21
-----------------

 * "git prune-packed" did not notice and complain against excess
   arguments given from the command line, which now it does.
   (merge 9b0bd87ed2 rj/prune-packed-excess-args later to maint).

 * Split-index fix.
   (merge 6e37c8ed3c nd/split-index-null-base-fix later to maint).

 * "git diff --no-index" may still want to access Git goodies like
   --ext-diff and --textconv, but so far these have been ignored,
   which has been corrected.
   (merge 287ab28bfa jk/diff-no-index-initialize later to maint).

 * Unify RPC code for smart http in protocol v0/v1 and v2, which fixes
   a bug in the latter (lack of authentication retry) and generally
   improves the code base.
   (merge a97d00799a jt/http-auth-proto-v2-fix later to maint).

 * The include file compat/bswap.h has been updated so that it is safe
   to (accidentally) include it more than once.
   (merge 33aa579a55 jk/guard-bswap-header later to maint).

 * The set of header files used by "make hdr-check" unconditionally
   included sha256/gcrypt.h, even when it is not used, causing the
   make target to fail.  We now skip it when GCRYPT_SHA256 is not in
   use.
   (merge f23aa18e7f rj/hdr-check-gcrypt-fix later to maint).

 * The Makefile uses 'find' utility to enumerate all the *.h header
   files, which is expensive on platforms with slow filesystems; it
   now optionally uses "ls-files" if working within a repository,
   which is a trick similar to how all sources are enumerated to run
   ETAGS on.
   (merge 92b88eba9f js/find-lib-h-with-ls-files-when-possible later to maint).

 * "git rebase" that was reimplemented in C did not set ORIG_HEAD
   correctly, which has been corrected.
   (merge cbd29ead92 js/rebase-orig-head-fix later to maint).

 * Dev support.
   (merge f545737144 js/stress-test-ui-tweak later to maint).

 * CFLAGS now can be tweaked when invoking Make while using
   DEVELOPER=YesPlease; this did not work well before.
   (merge 6d5d4b4e93 ab/makefile-help-devs-more later to maint).

 * "git fsck --connectivity-only" omits computation necessary to sift
   the objects that are not reachable from any of the refs into
   unreachable and dangling.  This is now enabled when dangling
   objects are requested (which is done by default, but can be
   overridden with the "--no-dangling" option).
   (merge 8d8c2a5aef jk/fsck-doc later to maint).

 * On platforms where "git fetch" is killed with SIGPIPE (e.g. OSX),
   the upload-pack that runs on the other end that hangs up after
   detecting an error could cause "git fetch" to die with a signal,
   which led to a flaky test.  "git fetch" now ignores SIGPIPE during
   the network portion of its operation (this is not a problem as we
   check the return status from our write(2)s).
   (merge 143588949c jk/no-sigpipe-during-network-transport later to maint).

 * A recent update broke "is this object available to us?" check for
   well-known objects like an empty tree (which should yield "yes",
   even when there is no on-disk object for an empty tree), which has
   been corrected.
   (merge f06ab027ef jk/virtual-objects-do-exist later to maint).

 * The setup code has been cleaned up to avoid leaks around the
   repository_format structure.
   (merge e8805af1c3 ma/clear-repository-format later to maint).

 * "git config --type=color ..." is meant to replace "git config \ 
--get-color"
   but there is a slight difference that wasn't documented, which is
   now fixed.
   (merge cd8e7593b9 jk/config-type-color-ends-with-lf later to maint).

 * When the "clean" filter can reduce the size of a huge file in the
   working tree down to a small "token" (a la Git LFS), there is no
   point in allocating a huge scratch area upfront, but the buffer is
   sized based on the original file size.  The convert mechanism now
   allocates very minimum and reallocates as it receives the output
   from the clean filter process.
   (merge 02156ab031 jh/resize-convert-scratch-buffer later to maint).

 * "git rebase" uses the refs/rewritten/ hierarchy to store its
   intermediate states, which inherently makes the hierarchy per
   worktree, but it didn't quite work well.
   (merge b9317d55a3 nd/rewritten-ref-is-per-worktree later to maint).

 * "git log -L<from>,<to>:<path>" with \ 
"-s" did not suppress the patch
   output as it should.  This has been corrected.
   (merge 05314efaea jk/line-log-with-patch later to maint).

 * "git worktree add" used to do a "find an available name with stat
   and then mkdir", which is race-prone.  This has been fixed by using
   mkdir and reacting to EEXIST in a loop.
   (merge 7af01f2367 ms/worktree-add-atomic-mkdir later to maint).

 * Build update for SHA-1 with collision detection.
   (merge 07a20f569b jk/sha1dc later to maint).

 * Build procedure has been fixed around use of asciidoctor instead of
   asciidoc.
   (merge 185f9a0ea0 ma/asciidoctor-fixes later to maint).

 * remote-http transport did not anonymize URLs reported in its error
   messages at places.
   (merge c1284b21f2 js/anonymize-remote-curl-diag later to maint).

 * Error messages given from the http transport have been updated so
   that they can be localized.
   (merge ed8b4132c8 js/remote-curl-i18n later to maint).

 * "git init" forgot to read platform-specific repository
   configuration, which made Windows port to ignore settings of
   core.hidedotfiles, for example.

 * A corner-case object name ambiguity while the sequencer machinery
   is working (e.g. "rebase -i -x") has been fixed.

 * "git format-patch" did not diagnose an error while opening the
   output file for the cover-letter, which has been corrected.
   (merge 2fe95f494c jc/format-patch-error-check later to maint).

 * "git checkout -f <branch>" while the index has an unmerged path
   incorrectly left some paths in an unmerged state, which has been
   corrected.

 * A corner case bug in the refs API has been corrected.
   (merge d3322eb28b jk/refs-double-abort later to maint).

 * Unicode update.
   (merge 584b62c37b bb/unicode-12 later to maint).

 * dumb-http walker has been updated to share more error recovery
   strategy with the normal codepath.

 * A buglet in configuration parser has been fixed.
   (merge 19e7fdaa58 nd/include-if-wildmatch later to maint).

 * The documentation for "git read-tree --reset -u" has been updated.
   (merge b5a0bd694c nd/read-tree-reset-doc later to maint).

 * Code clean-up around a much-less-important-than-it-used-to-be
   update_server_info() function.
   (merge b3223761c8 jk/server-info-rabbit-hole later to maint).

 * The message given when "git commit -a <paths>" errors out has been
   updated.
   (merge 5a1dbd48bc nd/commit-a-with-paths-msg-update later to maint).

 * "git cherry-pick --options A..B", after giving control back to the
   user to ask help resolving a conflicted step, did not honor the
   options it originally received, which has been corrected.

 * Various glitches in "git gc" around reflog handling have been fixed.

 * The code to read from commit-graph file has been cleanup with more
   careful error checking before using data read from it.

 * Performance fix around "git fetch" that grabs many refs.
   (merge b764300912 jt/fetch-pack-wanted-refs-optim later to maint).

 * Protocol v2 support in "git fetch-pack" of shallow clones has been
   corrected.

 * Performance fix around "git blame", especially in a linear history
   (which is the norm we should optimize for).
   (merge f892014943 dk/blame-keep-origin-blob later to maint).

 * Performance fix for "rev-list --parents -- pathspec".
   (merge 8320b1dbe7 jk/revision-rewritten-parents-in-prio-queue later to maint).

 * Updating the display with progress message has been cleaned up to
   deal better with overlong messages.
   (merge 545dc345eb sg/overlong-progress-fix later to maint).

 * "git blame -- path" in a non-bare repository starts blaming from
   the working tree, and the same command in a bare repository errors
   out because there is no working tree by definition.  The command
   has been taught to instead start blaming from the commit at HEAD,
   which is more useful.
   (merge a544fb08f8 sg/blame-in-bare-start-at-head later to maint).

 * An underallocation in the code to read the untracked cache
   extension has been corrected.
   (merge 3a7b45a623 js/untracked-cache-allocfix later to maint).

 * The code is updated to check the result of memory allocation before
   it is used in more places, by using xmalloc and/or xcalloc calls.
   (merge 999b951b28 jk/xmalloc later to maint).

 * The GETTEXT_POISON test option has been quite broken ever since it
   was made runtime-tunable, which has been fixed.
   (merge f88b9cb603 jc/gettext-test-fix later to maint).

 * Test fix on APFS that is incapable of store paths in Latin-1.
   (merge 3889149619 js/iso8895-test-on-apfs later to maint).

 * "git submodule foreach <command> --quiet" did not pass the option
   down correctly, which has been corrected.
   (merge a282f5a906 nd/submodule-foreach-quiet later to maint).

 * "git send-email" has been taught to use quoted-printable when the
   payload contains carriage-return.  The use of the mechanism is in
   line with the design originally added the codepath that chooses QP
   when the payload has overly long lines.
   (merge 74d76a1701 bc/send-email-qp-cr later to maint).

 * The recently added feature to add addresses that are on
   anything-by: trailers in 'git send-email' was found to be way too
   eager and considered nonsense strings as if they can be legitimate
   beginning of *-by: trailer.  This has been tightened.

 * Builds with gettext broke on recent macOS w/ Homebrew, which
   seems to have stopped including from /usr/local/include; this
   has been corrected.
   (merge 92a1377a2a js/macos-gettext-build later to maint).

 * Running "git add" on a repository created inside the current
   repository is an explicit indication that the user wants to add it
   as a submodule, but when the HEAD of the inner repository is on an
   unborn branch, it cannot be added as a submodule.  Worse, the files
   in its working tree can be added as if they are a part of the outer
   repository, which is not what the user wants.  These problems are
   being addressed.
   (merge f937bc2f86 km/empty-repo-is-still-a-repo later to maint).

 * "git cherry-pick" run with the "-x" or the \ 
"--signoff" option used
   to (and more importantly, ought to) clean up the commit log message
   with the --cleanup=space option by default, but this has been
   broken since late 2017.  This has been fixed.

 * When given a tag that points at a commit-ish, "git replace --graft"
   failed to peel the tag before writing a replace ref, which did not
   make sense because the old graft mechanism the feature wants to
   mimic only allowed to replace one commit object with another.
   This has been fixed.
   (merge ee521ec4cb cc/replace-graft-peel-tags later to maint).

 * Code tightening against a "wrong" object appearing where an object
   of a different type is expected, instead of blindly assuming that
   the connection between objects are correctly made.
   (merge 97dd512af7 tb/unexpected later to maint).

 * An earlier update for MinGW and Cygwin accidentally broke MSVC build,
   which has been fixed.
   (merge 22c3634c0f ss/msvc-path-utils-fix later to maint).

 * %(push:track) token used in the --format option to "git
   for-each-ref" and friends was not showing the right branch, which
   has been fixed.
   (merge c646d0934e dr/ref-filter-push-track-fix later to maint).

 * "make check-docs", "git help -a", etc. did not account \ 
for cases
   where a particular build may deliberately omit some subcommands,
   which has been corrected.

 * The logic to tell if a Git repository has a working tree protects
   "git branch -D" from removing the branch that is currently checked
   out by mistake.  The implementation of this logic was broken for
   repositories with unusual name, which unfortunately is the norm for
   submodules these days.  This has been fixed.
   (merge f3534c98e4 jt/submodule-repo-is-with-worktree later to maint).

 * AIX shared the same build issues with other BSDs around fileno(fp),
   which has been corrected.
   (merge ee662bf5c6 cc/aix-has-fileno-as-a-macro later to maint).

 * The autoconf generated configure script failed to use the right
   gettext() implementations from -libintl by ignoring useless stub
   implementations shipped in some C library, which has been
   corrected.
   (merge b71e56a683 vk/autoconf-gettext later to maint).

 * Fix index-pack perf test so that the repeated invocations always
   run in an empty repository, which emulates the initial clone
   situation better.
   (merge 775c71e16d jk/p5302-avoid-collision-check-cost later to maint).

 * A "ls-files" that emulates "find" to enumerate files in \ 
the working
   tree resulted in duplicated Makefile rules that caused the build to
   issue an unnecessary warning during a trial build after merge
   conflicts are resolved in working tree *.h files but before the
   resolved results are added to the index.  This has been corrected.

 * "git cherry-pick" (and "revert" that shares the same \ 
runtime engine)
   that deals with multiple commits got confused when the final step
   gets stopped with a conflict and the user concluded the sequence
   with "git commit".  Attempt to fix it by cleaning up the state
   files used by these commands in such a situation.
   (merge 4a72486de9 pw/clean-sequencer-state-upon-final-commit later to maint).

 * On a filesystem like HFS+, the names of the refs stored as filesystem
   entities may become different from what the end-user expects, just
   like files in the working tree get "renamed".  Work around the
   mismatch by paying attention to the core.precomposeUnicode
   configuration.
   (merge 8e712ef6fc en/unicode-in-refnames later to maint).

 * The code to generate the multi-pack idx file was not prepared to
   see too many packfiles and ran out of open file descriptor, which
   has been corrected.

 * To run tests for Git SVN, our scripts for CI used to install the
   git-svn package (in the hope that it would bring in the right
   dependencies).  This has been updated to install the more direct
   dependency, namely, libsvn-perl.
   (merge db864306cf sg/ci-libsvn-perl later to maint).

 * "git cvsexportcommit" running on msys did not expect cvsnt showed
   "cvs status" output with CRLF line endings.

 * The fsmonitor interface got out of sync after the in-core index
   file gets discarded, which has been corrected.
   (merge 398a3b0899 js/fsmonitor-refresh-after-discarding-index later to maint).

 * "git status" did not know that the "label" instruction in the
   todo-list "rebase -i -r" uses should not be shown as a hex object
   name.

 * A prerequisite check in the test suite to see if a working jgit is
   available was made more robust.
   (merge abd0f28983 tz/test-lib-check-working-jgit later to maint).

 * The codepath to parse :<path> that obtains the object name for an
   indexed object has been made more robust.

 * Code cleanup, docfix, build fix, etc.

git: updated to 2.21.0

Git 2.21 Release Notes
======================

Backward Compatibility Notes
----------------------------

 * Historically, the "-m" (mainline) option can only be used for "git
   cherry-pick" and "git revert" when working with a merge commit.
   This version of Git no longer warns or errors out when working with
   a single-parent commit, as long as the argument to the "-m" option
   is 1 (i.e. it has only one parent, and the request is to pick or
   revert relative to that first parent).  Scripts that relied on the
   behaviour may get broken with this change.

Updates since v2.20
-------------------

UI, Workflows & Features

 * The "http.version" configuration variable can be used with recent
   enough versions of cURL library to force the version of HTTP used
   to talk when fetching and pushing.

 * Small fixes and features for fast-export and fast-import, mostly on
   the fast-export side has been made.

 * "git push $there $src:$dst" rejects when $dst is not a fully
   qualified refname and it is not clear what the end user meant.  The
   codepath has been taught to give a clearer error message, and also
   guess where the push should go by taking the type of the pushed
   object into account (e.g. a tag object would want to go under
   refs/tags/).

 * "git checkout [<tree-ish>] path..." learned to report the \ 
number of
   paths that have been checked out of the index or the tree-ish,
   which gives it the same degree of noisy-ness as the case in which
   the command checks out a branch.  "git checkout -m <pathspec>" to
   undo conflict resolution gives a similar message.

 * "git quiltimport" learned "--keep-non-patch" option.

 * "git worktree remove" and "git worktree move" refused to \ 
work when
   there is a submodule involved.  This has been loosened to ignore
   uninitialized submodules.

 * "git cherry-pick -m1" was forbidden when picking a non-merge
   commit, even though there _is_ parent number 1 for such a commit.
   This was done to avoid mistakes back when "cherry-pick" was about
   picking a single commit, but is no longer useful with "cherry-pick"
   that can pick a range of commits.  Now the "-m$num" option is
   allowed when picking any commit, as long as $num names an existing
   parent of the commit.

 * Update "git multimail" from the upstream.

 * "git p4" update.

 * The "--format=<placeholder>" option of for-each-ref, branch \ 
and tag
   learned to show a few more traits of objects that can be learned by
   the object_info API.

 * "git rebase -i" learned to re-execute a command given with 'exec'
   to run after it failed the last time.

 * "git diff --color-moved-ws" updates.

 * Custom userformat "log --format" learned %S atom that stands for
   the tip the traversal reached the commit from, i.e. --source.

 * "git instaweb" learned to drive http.server that comes with
   "batteries included" Python installation (both Python2 & 3).

 * A new encoding UTF-16LE-BOM has been invented to force encoding to
   UTF-16 with BOM in little endian byte order, which cannot be directly
   generated by using iconv.

 * A new date format "--date=human" that morphs its output depending
   on how far the time is from the current time has been introduced.
   "--date=auto:human" can be used to use this new format (or any
   existing format) when the output is going to the pager or to the
   terminal, and otherwise the default format.

Performance, Internal Implementation, Development Support etc.

 * Code clean-up with optimization for the codepath that checks
   (non-)existence of loose objects.

 * More codepaths have become aware of working with in-core repository
   instances other than the default "the_repository".

 * The "strncat()" function is now among the banned functions.

 * Portability updates for the HPE NonStop platform.

 * Earlier we added "-Wformat-security" to developer builds, assuming
   that "-Wall" (which includes "-Wformat" which in turn is \ 
required
   to use "-Wformat-security") is always in effect.  This is not true
   when config.mak.autogen is in use, unfortunately.  This has been
   fixed by unconditionally adding "-Wall" to developer builds.

 * The loose object cache used to optimize existence look-up has been
   updated.

 * Flaky tests can now be repeatedly run under load with the
   "--stress" option.

 * Documentation/Makefile is getting prepared for manpage
   localization.

 * "git fetch-pack" now can talk the version 2 protocol.

 * sha-256 hash has been added and plumbed through the code to allow
   building Git with the "NewHash".

 * Debugging help for http transport.

 * "git fetch --deepen=<more>" has been corrected to work over v2
   protocol.

 * The code to walk tree objects has been taught that we may be
   working with object names that are not computed with SHA-1.

 * The in-core repository instances are passed through more codepaths.

 * Update the protocol message specification to allow only the limited
   use of scaled quantities.  This is to ensure potential compatibility
   issues will not get out of hand.

 * Micro-optimize the code that prepares commit objects to be walked
   by "git rev-list" when the commit-graph is available.

 * "git fetch" and "git upload-pack" learned to send all \ 
exchanges over
   the sideband channel while talking the v2 protocol.

 * The codepath to write out commit-graph has been optimized by
   following the usual pattern of visiting objects in in-pack order.

 * The codepath to show progress meter while writing out commit-graph
   file has been improved.

 * Cocci rules have been updated to encourage use of strbuf_addbuf().

 * "git rebase --merge" has been reimplemented by reusing the internal
   machinery used for "git rebase -i".

 * More code in "git bisect" has been rewritten in C.

 * Instead of going through "git-rebase--am" scriptlet to use the \ 
"am"
   backend, the built-in version of "git rebase" learned to drive the
   "am" backend directly.

 * The assumption to work on the single "in-core index" instance has
   been reduced from the library-ish part of the codebase.

 * The test lint learned to catch non-portable "sed" options.

 * "git pack-objects" learned another algorithm to compute the set of
   objects to send, that trades the resulting packfile off to save
   traversal cost to favor small pushes.

 * The travis CI scripts have been corrected to build Git with the
   compiler(s) of our choice.

 * "git submodule update" learned to abort early when core.worktree
   for the submodule is not set correctly to prevent spreading damage.

 * Test suite has been adjusted to run on Azure Pipeline.

 * Running "Documentation/doc-diff x" from anywhere other than the
   top-level of the working tree did not show the usage string
   correctly, which has been fixed.

 * Use of the sparse tool got easier to customize from the command
   line to help developers.

 * A new target "coverage-prove" to run the coverage test under
   "prove" has been added.

 * A flakey "p4" test has been removed.

 * The code and tests assume that the system supplied iconv() would
   always use BOM in its output when asked to encode to UTF-16 (or
   UTF-32), but apparently some implementations output big-endian
   without BOM.  A compile-time knob has been added to help such
   systems (e.g. NonStop) to add BOM to the output to increase
   portability.

Fixes since v2.20
-----------------

 * Updates for corner cases in merge-recursive.
   (merge cc4cb0902c en/merge-path-collision later to maint).

 * "git checkout frotz" (without any double-dash) avoids ambiguity by
   making sure 'frotz' cannot be interpreted as a revision and as a
   path at the same time.  This safety has been updated to check also
   a unique remote-tracking branch 'frotz' in a remote, when dwimming
   to create a local branch 'frotz' out of a remote-tracking branch
   'frotz' from a remote.
   (merge be4908f103 nd/checkout-dwim-fix later to maint).

 * Refspecs configured with "git -c var=val clone" did not propagate
   to the resulting repository, which has been corrected.
   (merge 7eae4a3ac4 sg/clone-initial-fetch-configuration later to maint).

 * A properly configured username/email is required under
   user.useConfigOnly in order to create commits; now "git stash"
   (even though it creates commit objects to represent stash entries)
   command is exempt from the requirement.
   (merge 3bc2111fc2 sd/stash-wo-user-name later to maint).

 * The http-backend CGI process did not correctly clean up the child
   processes it spawns to run upload-pack etc. when it dies itself,
   which has been corrected.
   (merge 02818a98d7 mk/http-backend-kill-children-before-exit later to maint).

 * "git rev-list --exclude-promisor-objects" had to take an object
   that does not exist locally (and is lazily available) from the
   command line without barfing, but the code dereferenced NULL.
   (merge 4cf67869b2 md/list-lazy-objects-fix later to maint).

 * The traversal over tree objects has learned to honor
   ":(attr:label)" pathspec match, which has been implemented only for
   enumerating paths on the filesystem.
   (merge 5a0b97b34c nd/attr-pathspec-in-tree-walk later to maint).

 * BSD port updates.
   (merge 4e3ecbd439 cb/openbsd-allows-reading-directory later to maint).
   (merge b6bdc2a0f5 cb/t5004-empty-tar-archive-fix later to maint).
   (merge 82cbc8cde2 cb/test-lint-cp-a later to maint).

 * Lines that begin with a certain keyword that come over the wire, as
   well as lines that consist only of one of these keywords, ought to
   be painted in color for easier eyeballing, but the latter was
   broken ever since the feature was introduced in 2.19, which has
   been corrected.
   (merge 1f67290450 hn/highlight-sideband-keywords later to maint).

 * "git log -G<regex>" looked for a hunk in the "git log \ 
-p" patch
   output that contained a string that matches the given pattern.
   Optimize this code to ignore binary files, which by default will
   not show any hunk that would match any pattern (unless textconv or
   the --text option is in effect, that is).
   (merge e0e7cb8080 tb/log-G-binary later to maint).

 * "git submodule update" ought to use a single job unless asked, but
   by mistake used multiple jobs, which has been fixed.
   (merge e3a9d1aca9 sb/submodule-fetchjobs-default-to-one later to maint).

 * "git stripspace" should be usable outside a git repository, but
   under the "-s" or "-c" mode, it didn't.
   (merge 957da75802 jn/stripspace-wo-repository later to maint).

 * Some of the documentation pages formatted incorrectly with
   Asciidoctor, which have been fixed.
   (merge b62eb1d2f4 ma/asciidoctor later to maint).

 * The core.worktree setting in a submodule repository should not be
   pointing at a directory when the submodule loses its working tree
   (e.g. getting deinit'ed), but the code did not properly maintain
   this invariant.

 * With zsh, "git cmd path<TAB>" was completed to "git cmd \ 
path name"
   when the completed path has a special character like SP in it,
   without any attempt to keep "path name" a single filename.  This
   has been fixed to complete it to "git cmd path\ name" just like
   Bash completion does.

 * The test suite tried to see if it is run under bash, but the check
   itself failed under some other implementations of shell (notably
   under NetBSD).  This has been corrected.
   (merge 54ea72f09c sg/test-bash-version-fix later to maint).

 * "git gc" and "git repack" did not close the open \ 
packfiles that
   they found unneeded before removing them, which didn't work on a
   platform incapable of removing an open file.  This has been
   corrected.
   (merge 5bdece0d70 js/gc-repack-close-before-remove later to maint).

 * The code to drive GIT_EXTERNAL_DIFF command relied on the string
   returned from getenv() to be non-volatile, which is not true, that
   has been corrected.
   (merge 6776a84dae kg/external-diff-save-env later to maint).

 * There were many places the code relied on the string returned from
   getenv() to be non-volatile, which is not true, that have been
   corrected.
   (merge 0da0e9268b jk/save-getenv-result later to maint).

 * The v2 upload-pack protocol implementation failed to honor
   hidden-ref configuration, which has been corrected.
   (merge e20b4192a3 jk/proto-v2-hidden-refs-fix later to maint).

 * "git fetch --recurse-submodules" may not fetch the necessary commit
   that is bound to the superproject, which is getting corrected.
   (merge be76c21282 sb/submodule-recursive-fetch-gets-the-tip later to maint).

 * "git rebase" internally runs "checkout" to switch between \ 
branches,
   and the command used to call the post-checkout hook, but the
   reimplementation stopped doing so, which is getting fixed.

 * "git add -e" got confused when the change it wants to let the user
   edit is smaller than the previous change that was left over in a
   temporary file.
   (merge fa6f225e01 js/add-e-clear-patch-before-stating later to maint).

 * "git p4" failed to update a shelved change when there were moved
   files, which has been corrected.
   (merge 7a10946ab9 ld/git-p4-shelve-update-fix later to maint).

 * The codepath to read from the commit-graph file attempted to read
   past the end of it when the file's table-of-contents was corrupt.

 * The compat/obstack code had casts that -Wcast-function-type
   compilation option found questionable.
   (merge 764473d257 sg/obstack-cast-function-type-fix later to maint).

 * An obvious typo in an assertion error message has been fixed.
   (merge 3c27e2e059 cc/test-ref-store-typofix later to maint).

 * In Git for Windows, "git clone \\server\share\path" etc. that uses
   UNC paths from command line had bad interaction with its shell
   emulation.

 * "git add --ignore-errors" did not work as advertised and instead
   worked as an unintended synonym for "git add --renormalize", which
   has been fixed.
   (merge e2c2a37545 jk/add-ignore-errors-bit-assignment-fix later to maint).

 * On a case-insensitive filesystem, we failed to compare the part of
   the path that is above the worktree directory in an absolute
   pathname, which has been corrected.

 * Asking "git check-attr" about a macro (e.g. "binary") on \ 
a specific
   path did not work correctly, even though "git check-attr -a" listed
   such a macro correctly.  This has been corrected.
   (merge 7b95849be4 jk/attr-macro-fix later to maint).

 * "git pack-objects" incorrectly used uninitialized mutex, which has
   been corrected.
   (merge edb673cf10 ph/pack-objects-mutex-fix later to maint).

 * "git checkout -b <new> [HEAD]" to create a new branch from the
   current commit and check it out ought to be a no-op in the index
   and the working tree in normal cases, but there are corner cases
   that do require updates to the index and the working tree.  Running
   it immediately after "git clone --no-checkout" is one of these
   cases that an earlier optimization kicked in incorrectly, which has
   been fixed.
   (merge 8424bfd45b bp/checkout-new-branch-optim later to maint).

 * "git diff --color-moved --cc --stat -p" did not work well due to
   funny interaction between a bug in color-moved and the rest, which
   has been fixed.
   (merge dac03b5518 jk/diff-cc-stat-fixes later to maint).

 * When GIT_SEQUENCE_EDITOR is set, the command was incorrectly
   started when modes of "git rebase" that implicitly uses the
   machinery for the interactive rebase are run, which has been
   corrected.
   (merge 891d4a0313 pw/no-editor-in-rebase-i-implicit later to maint).

 * The commit-graph facility did not work when in-core objects that
   are promoted from unknown type to commit (e.g. a commit that is
   accessed via a tag that refers to it) were involved, which has been
   corrected.
   (merge 4468d4435c sg/object-as-type-commit-graph-fix later to maint).

 * "git fetch" output cleanup.
   (merge dc40b24df4 nd/fetch-compact-update later to maint).

 * "git cat-file --batch" reported a dangling symbolic link by
   mistake, when it wanted to report that a given name is ambiguous.

 * Documentation around core.crlf has been updated.
   (merge c9446f0504 jk/autocrlf-overrides-eol-doc later to maint).

 * The documentation of "git commit-tree" said that the command
   understands "--gpg-sign" in addition to "-S", but the \ 
command line
   parser did not know about the longhand, which has been corrected.

 * "git rebase -x $cmd" did not reject multi-line command, even though
   the command is incapable of handling such a command.  It now is
   rejected upfront.
   (merge c762aada1a pw/rebase-x-sanity-check later to maint).

 * Output from "git help" was not correctly aligned, which has been
   fixed.
   (merge 6195a76da4 nd/help-align-command-desc later to maint).

 * The "git submodule summary" subcommand showed shortened commit
   object names by mechanically truncating them at 7-hexdigit, which
   has been improved to let "rev-parse --short" scale the length of
   the abbreviation with the size of the repository.
   (merge 0586a438f6 sh/submodule-summary-abbrev-fix later to maint).

 * The way the OSX build jobs updates its build environment used the
   "--quiet" option to "brew update" command, but it wasn't \ 
all that
   quiet to be useful.  The use of the option has been replaced with
   an explicit redirection to the /dev/null (which incidentally would
   have worked around a breakage by recent updates to homebrew, which
   has fixed itself already).
   (merge a1ccaedd62 sg/travis-osx-brew-breakage-workaround later to maint).

 * "git --work-tree=$there --git-dir=$here describe --dirty" did not
   work correctly as it did not pay attention to the location of the
   worktree specified by the user by mistake, which has been
   corrected.
   (merge c801170b0c ss/describe-dirty-in-the-right-directory later to maint).

 * "git fetch" over protocol v2 that needs to make a second connection
   to backfill tags did not clear a variable that holds shallow
   repository information correctly, leading to an access of freed
   piece of memory.

 * Some errors from the other side coming over smart HTTP transport
   were not noticed, which has been corrected.

 * Code cleanup, docfix, build fix, etc.
