the sideband channel while talking the v2 protocol.

compilation option found questionable.
* sg/obstack-cast-function-type-fix:
compat/obstack: fix -Wcast-function-type warnings
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.
* js/commit-graph-chunk-table-fix:
Makefile: correct example fuzz build
commit-graph: fix buffer read-overflow
commit-graph, fuzz: add fuzzer for commit-graph

by "git rev-list" when the commit-graph is available.
* jt/get-reference-with-commit-graph:
revision: use commit graph in get_reference()
Update the protocol message specification to allow only the limited
use of scaled quantities. This is ensure potential compatibility

Custom userformat "log --format" learned %S atom that stands for
the tip the traversal reached the commit from, i.e. --source.
* it/log-format-source:
log: add %S option (like --source) to log --format
"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.
* js/add-e-clear-patch-before-stating:
add --edit: truncate the patch file
The code to walk tree objects has been taught that we may be
working with object names that are not computed with SHA-1.

cache: make oidcpy always copy GIT_MAX_RAWSZ bytes
tree-walk: store object_id in a separate member
match-trees: use hashcpy to splice trees

protocol.

upload-pack: teach deepen-relative in protocol v2
fetch-pack: do not take shallow lock unnecessarily

test: test GIT_CURL_VERBOSE=1 shows an error
remote-curl: unset CURLOPT_FAILONERROR
remote-curl: define struct for CURLOPT_WRITEFUNCTION
http: enable keep_error for HTTP requests
http: support file handles for HTTP_KEEP_ERROR
"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.
* os/rebase-runs-post-checkout-hook:
rebase: run post-checkout hook on checkout
t5403: simplify by using a single repository
Add sha-256 hash and plug it through the code to allow building Git
with the "NewHash".
* bc/sha-256:

fetch: ensure submodule objects fetched

The v2 upload-pack protocol implementation failed to honor
hidden-ref configuration, which has been corrected.
An earlier attempt reverted out of 'next'.
* jk/proto-v2-hidden-refs-fix:
upload-pack: support hidden refs with protocol v2
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.
* jk/save-getenv-result:
builtin_diff(): read $GIT_DIFF_OPTS closer to use
merge-recursive: copy $GITHEAD strings

Prepare Documentation/Makefile so that manpage localization can
reuse it by overriding and tweaking the list of build products.

Documentation/Makefile add optional targets for l10n

rebase: introduce a shortcut for --reschedule-failed-exec
rebase: add a config option to default to --reschedule-failed-exec

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.
* kg/external-diff-save-env:
diff: ensure correct lifetime of external_diff_cmd
"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.
* js/gc-repack-close-before-remove:
gc/repack: release packs when needed
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.
* ot/ref-filter-object-info:
ref-filter: give uintmax_t to format with %PRIuMAX
ref-filter: add docs for new options
ref-filter: add tests for deltabase
ref-filter: add deltabase option
ref-filter: add tests for objectsize:disk
ref-filter: add check for negative file size
ref-filter: add objectsize:disk option
Flaky tests can now be repeatedly run under load with the
"--stress" option.

test-lib: add the '--stress' option to run a test repeatedly under load
test-lib-functions: introduce the 'test_set_port' helper function
test-lib: set $TRASH_DIRECTORY earlier

object-store: retire odb_load_loose_cache()
object-store: use one oid_array per subdirectory for loose cache
object-store: factor out odb_clear_loose_cache()
object-store: factor out odb_loose_cache()
An inherently racy test that caused intermittent failures has been
removed.
* tg/t5570-drop-racy-test:
Revert "t/lib-git-daemon: record daemon log"
t5570: drop racy test
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.
* jk/dev-build-format-security:
config.mak.dev: add -Wall, primarily for -Wformat, to help autoconf users
"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.
Technically this is a backward incompatible change; hopefully
nobody is relying on the error-checking behaviour.
* so/cherry-pick-always-allow-m1:
t3506: validate '-m 1 -ff' is now accepted for non-merge commits
t3502: validate '-m 1' argument is now accepted for non-merge commits
cherry-pick: do not error on non-merge commits when '-m 1' is specified
t3510: stop using '-m 1' to force failure mid-sequence of cherry-picks
"git worktree remove" and "git worktree move" refused to work when
there is a submodule involved. This has been loosened to ignore
uninitialized submodules.
* nd/worktree-remove-with-uninitialized-submodules:
worktree: allow to (re)move worktrees with uninitialized submodules
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.
* sg/test-bash-version-fix:
test-lib: check Bash version for '-x' without using shell arrays
Portability updates for the HPE NonStop platform.
* rb/hpe:
compat/regex/regcomp.c: define intptr_t and uintptr_t on NonStop
git-compat-util.h: add FLOSS headers for HPE NonStop
config.mak.uname: support for modern HPE NonStop config.
transport-helper: drop read/write errno checks
transport-helper: use xread instead of read
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.
* cy/zsh-completion-SP-in-path:
completion: treat results of git ls-tree as file paths
zsh: complete unquoted paths with spaces correctly
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.
* sb/submodule-unset-core-worktree-when-worktree-is-lost:
submodule deinit: unset core.worktree
submodule--helper: fix BUG message in ensure_core_worktree
submodule: unset core.worktree if no working tree is present
submodule update: add regression test with old style setups
Some of the documentation pages formatted incorrectly with
Asciidoctor, which have been fixed.
* ma/asciidoctor:
git-status.txt: render tables correctly under Asciidoctor
Documentation: do not nest open blocks
git-column.txt: fix section header
