"git submodule update" without pathspec should silently skip an

submodule--helper: fix initialization of warn_if_uninitialized
It is not obvious that the 'git rev-parse' builtin would use the sparse
index, but it is possible to parse paths out of the index using the
":<path>" syntax. The 'git rev-parse' output is only the OID of the
object found at that location, but otherwise behaves similarly to 'git
show :<path>'. This includes the failure conditions on directories and
the error messages depending on whether a path is in the worktree or
not.
The only code change required is to change the
command_requires_full_index setting in builtin/rev-parse.c, and we can
re-use many existing 'git show' tests for the rev-parse case.

The 'git show' command can take an input to request the state of an
object in the index. This can lead to parsing the index in order to load
a specific file entry. Without the change presented here, a sparse index
would expand to a full one, taking much longer than usual to access a
simple file.
There is one behavioral change that happens here, though: we now can
find a sparse directory entry within the index! Commands that previously
failed because we could not find an entry in the worktree or index now
succeed because we _do_ find an entry in the index.
There might be more work to do to make other situations succeed when
looking for an indexed tree, perhaps by looking at or updating the
cache-tree extension as needed. These situations include having a full
index or asking for a directory that is within the sparse-checkout cone
(and hence is not a sparse directory entry in the index).
For now, we demonstrate how the sparse index integration is extremely
simple for files outside of the cone as well as directories within the
cone. A later change will resolve this behavior around sparse
directories.

The .warn_if_uninitialized member was introduced by 48308681
(git submodule update: have a dedicated helper for cloning,
2016-02-29) to submodule_update_clone struct and initialized to
false. When c9911c93 (submodule--helper: teach update_data more
options, 2022-03-15) moved it to update_data struct, it started
to initialize it to true but this change was not explained in
its log message.
The member is set to true only when pathspec was given, and is
used when a submodule that matched the pathspec is found
uninitialized to give diagnostic message. "submodule update"
without pathspec is supposed to iterate over all submodules
(i.e. without pathspec limitation) and update only the
initialized submodules, and finding uninitialized submodules
during the iteration is a totally expected and normal thing that
should not be warned.

This only surfaced as a regression after 2.36 release, but the
breakage was already there with us for at least a year.
The diff_free() call is to be used after we completely finished with
a diffopt structure. After "git diff A B" finishes producing
output, calling it before process exit is fine. But there are
commands that prepares diff_options struct once, compares two sets
of paths, releases resources that were used to do the comparison,
then reuses the same diff_option struct to go on to compare the next
two sets of paths, like "git log -p".
After "git log -p" finishes showing a single commit, calling it
before it goes on to the next commit is NOT fine. There is a
mechanism, the .no_free member in diff_options struct, to help "git
log" to avoid calling diff_free() after showing each commit and
instead call it just one. When the mechanism was introduced in
e900d494 (diff: add an API for deferred freeing, 2021-02-11),
however, we forgot to do the same to "diff-tree --stdin", which *is*
a moral equivalent to "git log".
During 2.36 release cycle, we started clearing the pathspec in
diff_free(), so programs like gitk that runs
git diff-tree --stdin -- <pathspec>
downstream of a pipe, processing one commit after another, started
showing irrelevant comparison outside the given <pathspec> from the
second commit. The same commit, by forgetting to teach the .no_free
mechanism, broke "diff-tree --stdin -I<regexp>" and nobody noticed
it for over a year, presumably because it is so seldom used an
option.
But <pathspec> is a different story. The breakage was very
prominently visible and was reported immediately after 2.36 was
released.
Fix this breakage by mimicking how "git log" utilizes the .no_free
member so that "diff-tree --stdin" behaves more similarly to "log".
Protect the fix with a few new tests.

The --object-dir argument to 'git multi-pack-index' allows a user to
specify an alternate to use instead of the local $GITDIR. This is used
by third-party tools like VFS for Git to maintain the pack-files in a
"shared object cache" used by multiple clones.
On Windows, the user can specify a path using a Windows-style file path
with backslashes such as "C:\Path\To\ObjectDir". This same path style is
used in the .git/objects/info/alternates file, so it already matches the
path of that alternate. However, find_odb() converts these paths to
real-paths for the comparison, which use forward slashes. As of the
previous change, lookup_multi_pack_index() uses real-paths, so it
correctly finds the target multi-pack-index when given these paths.
Some commands such as 'git multi-pack-index repack' call child processes
using the object_dir value, so it can be helpful to convert the path to
the real-path before sending it to those locations.
Add a callback to convert the real path immediately upon parsing the
argument. We need to be careful that we don't store the exact value out
of get_object_directory() and free it, or we could corrupt a later use
of the_repository->objects->odb->path.
We don't use get_object_directory() for the initial instantiation in
cmd_multi_pack_index() because we need 'git multi-pack-index -h' to work
without a Git repository.

When "--current" is given to "git show-branch" running in the
"--reflog" mode, the code tries to reference a "reflog" message
that does not even exist. This is because the --current is not
prepared to work in that mode.
The reason "--current" exists is to support this request:
I list branches on the command line. These are the branchesI
care about and I use as anchoring points. I may or may not be on
one of these main branches. Please make sure I can view the
commits on the current branch with respect to what is in these
other branches.
And to serve that request, the code checks if the current branch is
among the ones listed on the command line, and adds it only if it is
not to the end of one array, which essentially lists the objects.
The reflog mode additionally uses another array to list reflog
messages, which the "--current" code does not add to. This leaves
one uninitialized slot at the end of the array of reflog messages,
and causes the program to show garbage or segfault.
Catch the unsupported (and meaningless) combination and exit with a
usage error.
There are other combinations of options that are incompatible but
have not been tested. Add test to cover them while adding coverage
for this new combination.

Extend the the release_revisions() function so that it frees the
"mailmap" in the "struct rev_info".
The log family of functions now calls the clear_mailmap() function
added in fa8afd18e5a (revisions API: provide and use a
release_revisions(), 2021-09-19), allowing us to whitelist some tests
with "TEST_PASSES_SANITIZE_LEAK=true".
Unfortunately having a pointer to a mailmap in "struct rev_info"
instead of an embedded member that we "own" get a bit messy, as can be
seen in the change to builtin/commit.c.
When we free() this data we won't be able to tell apart a pointer to a
"mailmap" on the heap from one on the stack. As seen in
ea57bc0d41 (log: add --use-mailmap option, 2013-01-05) the "log"
family allocates it on the heap, but in the find_author_by_nickname()
code added in ea16794e43 (commit: search author pattern against
mailmap, 2013-08-23) we allocated it on the stack instead.
Ideally we'd simply change that member to a "struct string_list
mailmap" and never free() the "mailmap" itself, but that would be a
much larger change to the revisions API.
We have code that needs to hand an existing "mailmap" to a "struct
rev_info", while we could change all of that, let's not go there
now.
The complexity isn't in the ownership of the "mailmap" per-se, but
that various things assume a "rev_info.mailmap == NULL" means "doesn't
want mailmap", if we changed that to an init'd "struct string_list
we'd need to carefully refactor things to change those assumptions.
Let's instead always free() it, and simply declare that if you add
such a "mailmap" it must be allocated on the heap. Any modern libc
will correctly panic if we free() a stack variable, so this should be
safe going forward.

As explained in preceding commits this is being done to use the

as we change it. In subsequent commits we'll then remove these

In preparation for having the "log" family of functions make wider use
of release_revisions() let's have them call it just before
exiting. This changes the "log", "whatchanged", "show",
"format-patch", etc. commands, all of which live in this file.
The release_revisions() API still only frees the "pending" member, but
will learn to release more members of "struct rev_info" in subsequent
commits.
In the case of "format-patch" revert the addition of UNLEAK() in
dee839a263 (format-patch: mark rev_info with UNLEAK, 2021-12-16),
which will cause several tests that previously passed under
"TEST_PASSES_SANITIZE_LEAK=true" to start failing.
In subsequent commits we'll now be able to use those tests to check
whether that part of the API is really leaking memory, and will fix
all of those memory leaks. Removing the UNLEAK() allows us to make
incremental progress in that direction. See [1] for further details
about this approach.
Note that the release_revisions() will not be sufficient to deal with
the code in cmd_show() added in 5d7eeee2ac (git-show: grok blobs,
trees and tags, too, 2006-12-14) which clobbers the "pending" array in
the case of "OBJ_COMMIT". That will need to be dealt with by some
future follow-up work.

Change the initialization of the "revision" member of "struct
stash_info" to be initialized vi a macro, and more importantly that
that initializing function be tasked to free it, usually via a "goto
cleanup" pattern.
Despite the "revision" name (and the topic of the series containing
this commit) the "stash info" has nothing to do with the "struct
rev_info". I'm making this change because in the subsequent commit
when we do want to free the "struct rev_info" via a "goto cleanup"
pattern we'd otherwise free() uninitialized memory in some cases, as
we only strbuf_init() the string in get_stash_info().
So while it's not the smallest possible change, let's convert all
users of this pattern in the file while we're at it.
A good follow-up to this change would be to change all the "ret = -1;
goto done;" in this file to instead use a "goto cleanup", and
initialize "int ret = -1" at the start of the relevant functions. That
would allow us to drop a lot of needless brace verbosity on two-line
"if" statements, but let's leave that alone for now.
To ensure that there's a 1=1 mapping between owners of the "struct
stash_info" and free_stash_info() change the assert_stash_ref()
function to be a trivial get_stash_info_assert() wrapper. The caller
will call free_stash_info(), and by returning -1 we'll eventually (via
!!ret) exit with status 1 anyway.

The users of the revision.[ch] API's "struct rev_info" are a major
source of memory leaks in the test suite under SANITIZE=leak, which in
turn adds a lot of noise when trying to mark up tests with
"TEST_PASSES_SANITIZE_LEAK=true".
The users of that API are largely one-shot, e.g. "git rev-list" or
"git log", or the "git checkout" and "git stash" being modified here
For these callers freeing the memory is arguably a waste of time, but
in many cases they've actually been trying to free the memory, and
just doing that in a buggy manner.
Let's provide a release_revisions() function for these users, and
start migrating them over per the plan outlined in [1]. Right now this
only handles the "pending" member of the struct, but more will be
added in subsequent commits.
Even though we only clear the "pending" member now, let's not leave a
trap in code like the pre-image of index_differs_from(), where we'd
start doing the wrong thing as soon as the release_revisions() learned
to clear its "diffopt". I.e. we need to call release_revisions() after
we've inspected any state in "struct rev_info".
This leaves in place e.g. clear_pathspec(&rev.prune_data) in
stash_working_tree() in builtin/stash.c, subsequent commits will teach
release_revisions() to free "prune_data" and other members that in
some cases are individually cleared by users of "struct rev_info" by
reaching into its members. Those subsequent commits will remove the
relevant calls to e.g. clear_pathspec().
We avoid amending code in index_differs_from() in diff-lib.c as well
as wt_status_collect_changes_index(), has_unstaged_changes() and
has_uncommitted_changes() in wt-status.c in a way that assumes that we
are already clearing the "diffopt" member. That will be handled in a
subsequent commit.

Fix two memory leaks in "struct rev_info" by freeing that memory in

however, so we can count on it being either NULL or something we
allocated. In the case of "extra_headers" let's add a local "char *"
variable to hold it, to avoid the eventual cast from "const char *"

The unpack-objects functionality is used by fetch, push, and fast-import
to turn the transfered data into object database entries when there are
fewer objects than the 'unpacklimit' setting.
By enabling an odb-transaction when unpacking objects, we can take advantage
of batched fsyncs.
Here are some performance numbers to justify batch mode for
unpack-objects, collected on a WSL2 Ubuntu VM.
Fsync Mode | Time for 90 objects (ms)
-------------------------------------
Off | 170
On,fsync | 760
On,batch | 230
Note that the default unpackLimit is 100 objects, so there's a 3x
benefit in the worst case. The non-batch mode fsync scales linearly
with the number of objects, so there are significant benefits even with
smaller numbers of objects.

This change enables odb-transactions for update-index infrastructure to
speed up adding new objects to the object database by leveraging the
batch fsync functionality.
There is some risk with this change, since under batch fsync, the object
files will be in a tmp-objdir until update-index is complete, so callers
using the --stdin option will not see them until update-index is done.
This risk is mitigated by flushing the ODB transaction prior to
reporting any verbose output so that objects will be visible to callers
that are synchronizing with update-index by snooping its output.

unconditionally recurse into directories if `-l` (long format) was
passed on the command line, regardless of whether or not we also pass
the `-r` (recursive) flag.
Fix this by making show_tree_long() return the value of `recurse`,
rather than always returning 1. This value is interpreted by
read_tree_at() to be a signal on whether or not to recurse.

"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".

"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 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.
