git: updated to 2.36.1

Git v2.36.1 Release Notes
=========================

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

 * "git submodule update" without pathspec should silently skip an
   uninitialized submodule, but it started to become noisy by mistake.

 * "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".

 * Regression fix for 2.36 where "git name-rev" started to sometimes
   reference strings after they are freed.

 * "git show <commit1> <commit2>... -- <pathspec>" \ 
lost the pathspec
   when showing the second and subsequent commits, which has been
   corrected.

 * "git fast-export -- <pathspec>" lost the pathspec when showing the
   second and subsequent commits, which has been corrected.

 * "git format-patch <args> -- <pathspec>" lost the \ 
pathspec when
   showing the second and subsequent commits, which has been
   corrected.

 * Get rid of a bogus and over-eager coccinelle rule.

 * Correct choices of C compilers used in various CI jobs.

Also contains minor documentation updates and code clean-ups.

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 2.35.0

Git 2.35 Release Notes
======================

Updates since Git 2.34
----------------------

Backward compatibility warts

 * "_" is now treated as any other URL-valid characters in an URL when
   matching the per-URL configuration variable names.

 * The color palette used by "git grep" has been updated to match that
   of GNU grep.

Note to those who build from the source

 * You may need to define NO_UNCOMPRESS2 Makefile macro if you build
   with zlib older than 1.2.9.

 * If your compiler cannot grok C99, the build will fail.  See the
   instruction at the beginning of git-compat-util.h if this happens
   to you.

UI, Workflows & Features

 * "git status --porcelain=v2" now show the number of stash entries
   with --show-stash like the normal output does.

 * "git stash" learned the "--staged" option to stash away \ 
what has
   been added to the index (and nothing else).

 * "git var GIT_DEFAULT_BRANCH" is a way to see what name is used for
   the newly created branch if "git init" is run.

 * Various operating modes of "git reset" have been made to work
   better with the sparse index.

 * "git submodule deinit" for a submodule whose .git metadata
   directory is embedded in its working tree refused to work, until
   the submodule gets converted to use the "absorbed" form where the
   metadata directory is stored in superproject, and a gitfile at the
   top-level of the working tree of the submodule points at it.  The
   command is taught to convert such submodules to the absorbed form
   as needed.

 * The completion script (in contrib/) learns that the "--date"
   option of commands from the "git log" family takes "human" and
   "auto" as valid values.

 * "Zealous diff3" style of merge conflict presentation has been added.

 * The "git log --format=%(describe)" placeholder has been extended to
   allow passing selected command-line options to the underlying "git
   describe" command.

 * "default" and "reset" have been added to our color palette.

 * The cryptographic signing using ssh keys can specify literal keys
   for keytypes whose name do not begin with the "ssh-" prefix by
   using the "key::" prefix mechanism (e.g. \ 
"key::ecdsa-sha2-nistp256").

 * "git fetch" without the "--update-head-ok" option ought \ 
to protect
   a checked out branch from getting updated, to prevent the working
   tree that checks it out to go out of sync.  The code was written
   before the use of "git worktree" got widespread, and only checked
   the branch that was checked out in the current worktree, which has
   been updated.

 * "git name-rev" has been tweaked to give output that is shorter and
   easier to understand.

 * "git apply" has been taught to ignore a message without a patch
   with the "--allow-empty" option.  It also learned to honor the
   "--quiet" option given from the command line.

 * The "init" and "set" subcommands in "git \ 
sparse-checkout" have been
   unified for a better user experience and performance.

 * Many git commands that deal with working tree files try to remove a
   directory that becomes empty (i.e. "git switch" from a branch that
   has the directory to another branch that does not would attempt
   remove all files in the directory and the directory itself).  This
   drops users into an unfamiliar situation if the command was run in
   a subdirectory that becomes subject to removal due to the command.
   The commands have been taught to keep an empty directory if it is
   the directory they were started in to avoid surprising users.

 * "git am" learns "--empty=(stop|drop|keep)" option to \ 
tweak what is
   done to a piece of e-mail without a patch in it.

 * The default merge message prepared by "git merge" records the name
   of the current branch; the name can be overridden with a new option
   to allow users to pretend a merge is made on a different branch.

 * The way "git p4" shows file sizes in its output has been updated to
   use human-readable units.

 * "git -c branch.autosetupmerge=inherit branch new old" makes \ 
"new"
   to have the same upstream as the "old" branch, instead of marking
   "old" itself as its upstream.

Performance, Internal Implementation, Development Support etc.

 * The use of errno as a means to carry the nature of error in the ref
   API implementation has been reworked and reduced.

 * Teach and encourage first-time contributors to this project to
   state the base commit when they submit their topic.

 * The command line completion for "git send-email" options have been
   tweaked to make it easier to keep it in sync with the command itself.

 * Ensure that the sparseness of the in-core index matches the
   index.sparse configuration specified by the repository immediately
   after the on-disk index file is read.

 * Code clean-up to eventually allow information on remotes defined
   for an arbitrary repository to be read.

 * Build optimization.

 * Tighten code for testing pack-bitmap.

 * Weather balloon to break people with compilers that do not support
   C99.

 * The "reftable" backend for the refs API, without integrating into
   the refs subsystem, has been added.

 * More tests are marked as leak-free.

 * The test framework learns to list unsatisfied test prerequisites,
   and optionally error out when prerequisites that are expected to be
   satisfied are not.

 * The default setting for trace2 event nesting was too low to cause
   test failures, which is worked around by bumping it up in the test
   framework.

 * Drop support for TravisCI and update test workflows at GitHub.

 * Many tests that used to need GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME
   mechanism to force "git" to use 'master' as the default name for
   the initial branch no longer need it; the use of the mechanism from
   them have been removed.

 * Allow running our tests while disabling fsync.

 * Document the parameters given to the reflog entry iterator callback
   functions.
   (merge e6e94f34b2 jc/reflog-iterator-callback-doc later to maint).

 * The test helper for refs subsystem learned to write bogus and/or
   nonexistent object name to refs to simulate error situations we
   want to test Git in.

 * "diff --histogram" optimization.

 * Weather balloon to find compilers that do not grok variable
   declaration in the for() loop.

 * diff and blame commands have been taught to work better with sparse
   index.

 * The chainlint test script linter in the test suite has been updated.

 * The DEVELOPER=yes build uses -std=gnu99 now.

 * "git format-patch" uses a single rev_info instance and then exits.
   Mark the structure with UNLEAK() macro to squelch leak sanitizer.

 * New interface into the tmp-objdir API to help in-core use of the
   quarantine feature.

 * Broken &&-chains in the test scripts have been corrected.

 * The RCS keyword substitution in "git p4" used to be done assuming
   that the contents are UTF-8 text, which can trigger decoding
   errors.  We now treat the contents as a bytestring for robustness
   and correctness.

 * The conditions to choose different definitions of the FLEX_ARRAY
   macro for vendor compilers has been simplified to make it easier to
   maintain.

 * Correctness and performance update to "diff --color-moved" feature.

 * "git upload-pack" (the other side of "git fetch") used a \ 
8kB buffer
   but most of its payload came on 64kB "packets".  The buffer size
   has been enlarged so that such a packet fits.

 * "git fetch" and "git pull" are now declared sparse-index \ 
clean.
   Also "git ls-files" learns the "--sparse" option to help \ 
debugging.

 * Similar message templates have been consolidated so that
   translators need to work on fewer number of messages.

Fixes since v2.34
-----------------

 * "git grep" looking in a blob that has non-UTF8 payload was
   completely broken when linked with certain versions of PCREv2
   library in the latest release.

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

 * "git pull" with any strategy when the other side is behind us
   should succeed as it is a no-op, but doesn't.

 * An earlier change in 2.34.0 caused JGit application (that abused
   GIT_EDITOR mechanism when invoking "git config") to get stuck with
   a SIGTTOU signal; it has been reverted.

 * An earlier change that broke .gitignore matching has been reverted.

 * Things like "git -c branch.sort=bogus branch new HEAD", i.e. the
   operation modes of the "git branch" command that do not need the
   sort key information, no longer errors out by seeing a bogus sort
   key.
   (merge 98e7ab6d42 jc/fix-ref-sorting-parse later to maint).

 * The compatibility implementation for unsetenv(3) were written to
   mimic ancient, non-POSIX, variant seen in an old glibc; it has been
   changed to return an integer to match the more modern era.
   (merge a38989bd5b jc/unsetenv-returns-an-int later to maint).

 * The clean/smudge conversion code path has been prepared to better
   work on platforms where ulong is narrower than size_t.
   (merge 596b5e77c9 mc/clean-smudge-with-llp64 later to maint).

 * Redact the path part of packfile URI that appears in the trace output.
   (merge 0ba558ffb1 if/redact-packfile-uri later to maint).

 * CI has been taught to catch some Unicode directional formatting
   sequence that can be used in certain mischief.
   (merge 0e7696c64d js/ci-no-directional-formatting later to maint).

 * The "--date=format:<strftime>" gained a workaround for the lack of
   system support for a non-local timezone to handle "%s" placeholder.
   (merge 9b591b9403 jk/strbuf-addftime-seconds-since-epoch later to maint).

 * The "merge" subcommand of "git jump" (in contrib/) \ 
silently ignored
   pathspec and other parameters.
   (merge 67ba13e5a4 jk/jump-merge-with-pathspec later to maint).

 * The code to decode the length of packed object size has been
   corrected.
   (merge 34de5b8eac jt/pack-header-lshift-overflow later to maint).

 * The advice message given by "git pull" when the user hasn't made a
   choice between merge and rebase still said that the merge is the
   default, which no longer is the case.  This has been corrected.
   (merge 71076d0edd ah/advice-pull-has-no-preference-between-rebase-and-merge \ 
later to maint).

 * "git fetch", when received a bad packfile, can fail with SIGPIPE.
   This wasn't wrong per-se, but we now detect the situation and fail
   in a more predictable way.
   (merge 2a4aed42ec jk/fetch-pack-avoid-sigpipe-to-index-pack later to maint).

 * The function to cull a child process and determine the exit status
   had two separate code paths for normal callers and callers in a
   signal handler, and the latter did not yield correct value when the
   child has caught a signal.  The handling of the exit status has
   been unified for these two code paths.  An existing test with
   flakiness has also been corrected.
   (merge 5263e22cba jk/t7006-sigpipe-tests-fix later to maint).

 * When a non-existent program is given as the pager, we tried to
   reuse an uninitialized child_process structure and crashed, which
   has been fixed.
   (merge f917f57f40 em/missing-pager later to maint).

 * The single-key-input mode in "git add -p" had some code to handle
   keys that generate a sequence of input via ReadKey(), which did not
   handle end-of-file correctly, which has been fixed.
   (merge fc8a8126df cb/add-p-single-key-fix later to maint).

 * "git rebase -x" added an unnecessary 'exec' instructions before
   'noop', which has been corrected.
   (merge cc9dcdee61 en/rebase-x-fix later to maint).

 * When the "git push" command is killed while the receiving end is
   trying to report what happened to the ref update proposals, the
   latter used to die, due to SIGPIPE.  The code now ignores SIGPIPE
   to increase our chances to run the post-receive hook after it
   happens.
   (merge d34182b9e3 rj/receive-pack-avoid-sigpipe-during-status-reporting later \ 
to maint).

 * "git worktree add" showed "Preparing worktree" message to the
   standard output stream, but when it failed, the message from die()
   went to the standard error stream.  Depending on the order the
   stdio streams are flushed at the program end, this resulted in
   confusing output.  It has been corrected by sending all the chatty
   messages to the standard error stream.
   (merge b50252484f es/worktree-chatty-to-stderr later to maint).

 * Coding guideline document has been updated to clarify what goes to
   standard error in our system.
   (merge e258eb4800 es/doc-stdout-vs-stderr later to maint).

 * The sparse-index/sparse-checkout feature had a bug in its use of
   the matching code to determine which path is in or outside the
   sparse checkout patterns.
   (merge 8c5de0d265 ds/sparse-deep-pattern-checkout-fix later to maint).

 * "git rebase -x" by mistake started exporting the GIT_DIR and
   GIT_WORK_TREE environment variables when the command was rewritten
   in C, which has been corrected.
   (merge 434e0636db en/rebase-x-wo-git-dir-env later to maint).

 * When "git log" implicitly enabled the "decoration" processing
   without being explicitly asked with "--decorate" option, it failed
   to read and honor the settings given by the "--decorate-refs"
   option.

 * "git fetch --set-upstream" did not check if there is a current
   branch, leading to a segfault when it is run on a detached HEAD,
   which has been corrected.
   (merge 17baeaf82d ab/fetch-set-upstream-while-detached later to maint).

 * Among some code paths that ask an yes/no question, only one place
   gave a prompt that looked different from the others, which has been
   updated to match what the others create.
   (merge 0fc8ed154c km/help-prompt-fix later to maint).

 * "git log --invert-grep --author=<name>" used to exclude commits
   written by the given author, but now "--invert-grep" only affects
   the matches made by the "--grep=<pattern>" option.
   (merge 794c000267 rs/log-invert-grep-with-headers later to maint).

 * "git grep --perl-regexp" failed to match UTF-8 characters with
   wildcard when the pattern consists only of ASCII letters, which has
   been corrected.
   (merge 32e3e8bc55 rs/pcre2-utf later to maint).

 * Certain sparse-checkout patterns that are valid in non-cone mode
   led to segfault in cone mode, which has been corrected.

 * Use of certain "git rev-list" options with "git fast-export"
   created nonsense results (the worst two of which being "--reverse"
   and "--invert-grep --grep=<foo>").  The use of \ 
"--first-parent" is
   made to behave a bit more sensible than before.
   (merge 726a228dfb ws/fast-export-with-revision-options later to maint).

 * Perf tests were run with end-user's shell, but it has been
   corrected to use the shell specified by $TEST_SHELL_PATH.
   (merge 9ccab75608 ja/perf-use-specified-shell later to maint).

 * Fix dependency rules to generate hook-list.h header file.
   (merge d3fd1a6667 ab/makefile-hook-list-dependency-fix later to maint).

 * "git stash" by default triggers its "push" action, but its
   implementation also made "git stash -h" to show short help only for
   "git stash push", which has been corrected.
   (merge ca7990cea5 ab/do-not-limit-stash-help-to-push later to maint).

 * "git apply --3way" bypasses the attempt to do a three-way
   application in more cases to address the regression caused by the
   recent change to use direct application as a fallback.
   (merge 34d607032c jz/apply-3-corner-cases later to maint).

 * Fix performance-releated bug in "git subtree" (in contrib/).
   (merge 3ce8888fb4 jl/subtree-check-parents-argument-passing-fix later to maint).

 * Extend the guidance to choose the base commit to build your work
   on, and hint/nudge contributors to read others' changes.
   (merge fdfae830f8 jc/doc-submitting-patches-choice-of-base later to maint).

 * A corner case bug in the ort merge strategy has been corrected.
   (merge d30126c20d en/merge-ort-renorm-with-rename-delete-conflict-fix later \ 
to maint).

 * "git stash apply" forgot to attempt restoring untracked files when
   it failed to restore changes to tracked ones.
   (merge 71cade5a0b en/stash-df-fix later to maint).

 * Calling dynamically loaded functions on Windows has been corrected.
   (merge 4a9b204920 ma/windows-dynload-fix later to maint).

 * Some lockfile code called free() in signal-death code path, which
   has been corrected.
   (merge 58d4d7f1c5 ps/lockfile-cleanup-fix later to maint).

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

Log message:
git: updated to 2.34.1

Git v2.34.1 Release Notes
=========================

This release is primarily to fix a handful of regressions in Git 2.34.

Fixes since v2.34
-----------------

 * "git grep" looking in a blob that has non-UTF8 payload was
   completely broken when linked with certain versions of PCREv2
   library in the latest release.

 * "git pull" with any strategy when the other side is behind us
   should succeed as it is a no-op, but doesn't.

 * An earlier change in 2.34.0 caused JGit application (that abused
   GIT_EDITOR mechanism when invoking "git config") to get stuck with
   a SIGTTOU signal; it has been reverted.

 * An earlier change that broke .gitignore matching has been reverted.

 * SubmittingPatches document gained a syntactically incorrect mark-up,
   which has been corrected.

Log message:
git: updated to 2.34.0

Git 2.34 Release Notes
======================

Updates since Git 2.33
----------------------

Backward compatibility notes

 * The "--preserve-merges" option of "git rebase" has been \ 
removed.

UI, Workflows & Features

 * Pathname expansion (like "~username/") learned a way to specify a
   location relative to Git installation (e.g. its $sharedir which is
   $(prefix)/share), with "%(prefix)".

 * The `ort` strategy is used instead of `recursive` as the default
   merge strategy.

 * The userdiff pattern for "java" language has been updated.

 * "git rebase" by default skips changes that are equivalent to
   commits that are already in the history the branch is rebased onto;
   give messages when this happens to let the users be aware of
   skipped commits, and also teach them how to tell "rebase" to keep
   duplicated changes.

 * The advice message that "git cherry-pick" gives when it asks
   conflicted replay of a commit to be resolved by the end user has
   been updated.

 * After "git clone --recurse-submodules", all submodules are cloned
   but they are not by default recursed into by other commands.  With
   submodule.stickyRecursiveClone configuration set, submodule.recurse
   configuration is set to true in a repository created by "clone"
   with "--recurse-submodules" option.

 * The logic for auto-correction of misspelt subcommands learned to go
   interactive when the help.autocorrect configuration variable is set
   to 'prompt'.

 * "git maintenance" scheduler learned to use systemd timers as a
   possible backend.

 * "git diff --submodule=diff" showed failure from run_command() when
   trying to run diff inside a submodule, when the user manually
   removes the submodule directory.

 * "git bundle unbundle" learned to show progress display.

 * In cone mode, the sparse-index code path learned to remove ignored
   files (like build artifacts) outside the sparse cone, allowing the
   entire directory outside the sparse cone to be removed, which is
   especially useful when the sparse patterns change.

 * Taking advantage of the CGI interface, http-backend has been
   updated to enable protocol v2 automatically when the other side
   asks for it.

 * The credential-cache helper has been adjusted to Windows.

 * The error in "git help no-such-git-command" is handled better.

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

 * The ref iteration code used to optionally allow dangling refs to be
   shown, which has been tightened up.

 * "git add", "git mv", and "git rm" have been \ 
adjusted to avoid
   updating paths outside of the sparse-checkout definition unless
   the user specifies a "--sparse" option.

 * "git repack" has been taught to generate multi-pack reachability
   bitmaps.

 * "git fsck" has been taught to report mismatch between expected and
   actual types of an object better.

 * In addition to GnuPG, ssh public crypto can be used for object and
   push-cert signing.  Note that this feature cannot be used with
   ssh-keygen from OpenSSH 8.7, whose support for it is broken.  Avoid
   using it unless you update to OpenSSH 8.8.

 * "git log --grep=string --author=name" learns to highlight hits just
   like "git grep string" does.

Performance, Internal Implementation, Development Support etc.

 * "git bisect" spawned "git show-branch" only to \ 
pretty-print the
   title of the commit after checking out the next version to be
   tested; this has been rewritten in C.

 * "git add" can work better with the sparse index.

 * Support for ancient versions of cURL library (pre 7.19.4) has been
   dropped.

 * A handful of tests that assumed implementation details of files
   backend for refs have been cleaned up.

 * trace2 logs learned to show parent process name to see in what
   context Git was invoked.

 * Loading of ref tips to prepare for common ancestry negotiation in
   "git fetch-pack" has been optimized by taking advantage of the
   commit graph when available.

 * Remind developers that the userdiff patterns should be kept simple
   and permissive, assuming that the contents they apply are always
   syntactically correct.

 * The current implementation of GIT_TEST_FAIL_PREREQS is broken in
   that checking for the lack of a prerequisite would not work.  Avoid
   the use of "if ! test_have_prereq X" in a test script.

 * The revision traversal API has been optimized by taking advantage
   of the commit-graph, when available, to determine if a commit is
   reachable from any of the existing refs.

 * "git fetch --quiet" optimization to avoid useless computation of
   info that will never be displayed.

 * Callers from older advice_config[] based API has been updated to
   use the newer advice_if_enabled() and advice_enabled() API.

 * Teach "test_pause" and "debug" helpers to allow using the \ 
HOME and
   TERM environment variables the user usually uses.

 * "make INSTALL_STRIP=-s install" allows the installation step to use
   "install -s" to strip the binaries as they get installed.

 * Code that handles large number of refs in the "git fetch" code
   path has been optimized.

 * The reachability bitmap file used to be generated only for a single
   pack, but now we've learned to generate bitmaps for history that
   span across multiple packfiles.

 * The code to make "git grep" recurse into submodules has been
   updated to migrate away from the "add submodule's object store as
   an alternate object store" mechanism (which is suboptimal).

 * The tracing of process ancestry information has been enhanced.

 * Reduce number of write(2) system calls while sending the
   ref advertisement.

 * Update the build procedure to use the "-pedantic" build when
   DEVELOPER makefile macro is in effect.

 * Large part of "git submodule add" gets rewritten in C.

 * The run-command API has been updated so that the callers can easily
   ask the file descriptors open for packfiles to be closed immediately
   before spawning commands that may trigger auto-gc.

 * An oddball OPTION_ARGUMENT feature has been removed from the
   parse-options API.

 * The mergesort implementation used to sort linked list has been
   optimized.

 * Remove external declaration of functions that no longer exist.

 * "git multi-pack-index write --bitmap" learns to propagate the
   hashcache from original bitmap to resulting bitmap.

 * CI learns to run the leak sanitizer builds.

 * "git grep --recurse-submodules" takes trees and blobs from the
   submodule repository, but the textconv settings when processing a
   blob from the submodule is not taken from the submodule repository.
   A test is added to demonstrate the issue, without fixing it.

 * Teach "git help -c" into helping the command line completion of
   configuration variables.

 * When "git cmd -h" shows more than one line of usage text (e.g.
   the cmd subcommand may take sub-sub-command), parse-options API
   learned to align these lines, even across i18n/l10n.

 * Prevent "make sparse" from running for the source files that
   haven't been modified.

 * The code path to write a new version of .midx multi-pack index files
   has learned to release the mmaped memory holding the current
   version of .midx before removing them from the disk, as some
   platforms do not allow removal of a file that still has mapping.

 * A new feature has been added to abort early in the test framework.

Fixes since v2.33
-----------------

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

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

 * "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.

 * 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.  This fixes a regression caused by
   recent "-3way first and fall back to direct application" change.

 * 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.

 * A few kinds of changes "git status" can show were not documented.
   (merge d2a534c515 ja/doc-status-types-and-copies later to maint).

 * The mergesort implementation used to sort linked list has been
   optimized.
   (merge c90cfc225b rs/mergesort later to maint).

 * An editor session launched during a Git operation (e.g. during 'git
   commit') can leave the terminal in a funny state.  The code path
   has updated to save the terminal state before, and restore it
   after, it spawns an editor.
   (merge 3d411afabc cm/save-restore-terminal later to maint).

 * "git cat-file --batch" with the "--batch-all-objects" \ 
option is
   supposed to iterate over all the objects found in a repository, but
   it used to translate these object names using the replace mechanism,
   which defeats the point of enumerating all objects in the repository.
   This has been corrected.
   (merge bf972896d7 jk/cat-file-batch-all-wo-replace later to maint).

 * Recent sparse-index work broke safety against attempts to add paths
   with trailing slashes to the index, which has been corrected.
   (merge c8ad9d04c6 rs/make-verify-path-really-verify-again later to maint).

 * The "--color-lines" and "--color-by-age" options of \ 
"git blame"
   have been missing, which are now documented.
   (merge 8c32856133 bs/doc-blame-color-lines later to maint).

 * The PATH used in CI job may be too wide and let incompatible dlls
   to be grabbed, which can cause the build&test to fail.  Tighten it.
   (merge 7491ef6198 js/windows-ci-path-fix later to maint).

 * Avoid performance measurements from getting ruined by gc and other
   housekeeping pauses interfering in the middle.
   (merge be79131a53 rs/disable-gc-during-perf-tests later to maint).

 * Stop "git add --dry-run" from creating new blob and tree objects.
   (merge e578d0311d rs/add-dry-run-without-objects later to maint).

 * "git commit" gave duplicated error message when the object store
   was unwritable, which has been corrected.
   (merge 4ef91a2d79 ab/fix-commit-error-message-upon-unwritable-object-store \ 
later to maint).

 * Recent sparse-index addition, namely any use of index_name_pos(),
   can expand sparse index entries and breaks any code that walks
   cache-tree or existing index entries.  One such instance of such a
   breakage has been corrected.

 * The xxdiff difftool backend can exit with status 128, which the
   difftool-helper that launches the backend takes as a significant
   failure, when it is not significant at all.  Work it around.
   (merge 571f4348dd da/mergetools-special-case-xxdiff-exit-128 later to maint).

 * Improve test framework around unwritable directories.
   (merge 5d22e18965 ab/test-cleanly-recreate-trash-directory later to maint).

 * "git push" client talking to an HTTP server did not diagnose the
   lack of the final status report from the other side correctly,
   which has been corrected.
   (merge c5c3486f38 jk/http-push-status-fix later to maint).

 * Update "git archive" documentation and give explicit mention on the
   compression level for both zip and tar.gz format.
   (merge c4b208c309 bs/archive-doc-compression-level later to maint).

 * Drop "git sparse-checkout" from the list of common commands.
   (merge 6a9a50a8af sg/sparse-index-not-that-common-a-command later to maint).

 * "git branch -c/-m new old" was not described to copy config, which
   has been corrected.
   (merge 8252ec300e jc/branch-copy-doc later to maint).

 * Squelch over-eager warning message added during this cycle.

 * Fix long-standing shell syntax error in the completion script.
   (merge 46b0585286 re/completion-fix-test-equality later to maint).

 * Teach "git commit-graph" command not to allow using replace objects
   at all, as we do not use the commit-graph at runtime when we see
   object replacement.
   (merge 095d112f8c ab/ignore-replace-while-working-on-commit-graph later to maint).

 * "git pull --no-verify" did not affect the underlying "git \ 
merge".
   (merge 47bfdfb3fd ar/fix-git-pull-no-verify later to maint).

 * One CI task based on Fedora image noticed a not-quite-kosher
   construct recently, which has been corrected.

 * "git pull --ff-only" and "git pull --rebase --ff-only" \ 
should make
   it a no-op to attempt pulling from a remote that is behind us, but
   instead the command errored out by saying it was impossible to
   fast-forward, which may technically be true, but not a useful thing
   to diagnose as an error.  This has been corrected.

 * The way Cygwin emulates a unix-domain socket, on top of which the
   simple-ipc mechanism is implemented, can race with the program on
   the other side that wants to use the socket, and briefly make it
   appear as a regular file before lstat(2) starts reporting it as a
   socket.  We now have a workaround on the side that connects to a
   unix domain socket.

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

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.
