builtin/receive-pack.c: remove redundant 'if'

"git fetch --recurse-submodules" from multiple remotes (either from
a remote group, or "--all") used to make one extra "git fetch" in
the submodules, which has been corrected.

The way "git fetch" without "--update-head-ok" ensures that HEAD in

When using a multi-pack bitmap, pack-objects will try to perform its
traversal using a call to `traverse_bitmap_commit_list()`, which calls
`add_object_entry_from_bitmap()` to add each object it finds to its
packing list.
This path can cause pack-objects to add objects from packs that don't
have open pack_fds on them, by avoiding a call to `is_pack_valid()`.
This is because we only call `is_pack_valid()` on the preferred pack (in
order to do verbatim reuse via `reuse_partial_packfile_from_bitmap()`)
and not others when loading a MIDX bitmap.
In this case, `add_object_entry_from_bitmap()` will check whether it
wants each object entry by calling `want_object_in_pack()`, which will
call `want_found_object` (since its caller already supplied a
`found_pack`). In most cases (particularly without `--local`, and when
`ignored_packed_keep_on_disk` and `ignored_packed_keep_in_core` are
both "0"), we'll take the entry from the pack contained in the MIDX
bitmap, all without an open pack_fd.
When we then try to use that entry later to assemble the actual pack,
we'll be susceptible to any simultaneous writers moving that pack out of
the way (e.g., due to a concurrent repack) without having an open file
descriptor, causing races that result in errors like:
remote: Enumerating objects: 1498802, done.
remote: fatal: packfile ./objects/pack/pack-e57d433b5a588daa37fbe946e2b28dfaec03a93e.pack cannot be accessed
remote: aborting due to possible repository corruption on the remote side.
This race can happen even with multi-pack bitmaps, since we may open a
MIDX bitmap that is being rewritten long before its packs are actually
unlinked.
Work around this by calling `is_pack_valid()` from within
`want_found_object()`, matching the behavior in
`want_object_in_pack_one()` (which has an analogous call). Most calls to
`is_pack_valid()` should be basically no-ops, since only the first call
requires us to open a file (subsequent calls realize the file is already
open, and return immediately).
Importantly, when `want_object_in_pack()` is given a non-NULL
`*found_pack`, but `want_found_object()` rejects the copy of the object
in that pack, we must reset `*found_pack` and `*found_offset` to NULL
and 0, respectively. Failing to do so could lead to other checks in
`want_object_in_pack()` (such as `want_object_in_pack_one()`) using the
same (invalid) pack as `*found_pack`, meaning that we don't call
`is_pack_valid()` because `p == *found_pack`. This can lead the caller
to believe it can use a copy of an object from an invalid pack.
An alternative approach to closing this race would have been to call
`is_pack_valid()` on _all_ packs in a multi-pack bitmap on load. This
has a couple of problems:
- it is unnecessarily expensive in the cases where we don't actually
need to open any packs (e.g., in `git rev-list --use-bitmap-index
--count`)
- more importantly, it means any time we would have hit this race,
we'll avoid using bitmaps altogether, leading to significant
slowdowns by forcing a full object traversal

A subsequent patch will teach `want_object_in_pack()` to set its
`*found_pack` and `*found_offset` poitners to NULL when the provided
pack does not pass the `is_pack_valid()` check.
The `--stdin-packs` mode of `pack-objects` is not quite prepared to
handle this. To prepare it for this change, do the following two things:
- Ensure provided packs pass the `is_pack_valid()` check when
collecting the caller-provided packs into the "included" and
"excluded" lists.
- Gracefully handle any _invalid_ packs being passed to
`want_object_in_pack()`.
Calling `is_pack_valid()` early on makes it substantially less likely
that we will have to deal with a pack going away, since we'll have an
open file descriptor on its contents much earlier.
But even packs with open descriptors can become invalid in the future if
we (a) hit our open descriptor limit, forcing us to close some open
packs, and (b) one of those just-closed packs has gone away in the
meantime.
`add_object_entry_from_pack()` depends on having a non-NULL
`*found_pack`, since it passes that pointer to `packed_object_info()`,
meaning that we would SEGV if the pointer became NULL (like we propose
to do in `want_object_in_pack()` in the following patch).
But avoiding calling `packed_object_info()` entirely is OK, too, since
its only purpose is to identify which objects in the included packs are
commits, so that they can form the tips of the advisory traversal used
to discover the object namehashes.
Failing to do this means that at worst we will produce lower-quality
deltas, but it does not prevent us from generating the pack as long as
we can find a copy of each object from the disappearing pack in some
other part of the repository.

Before calling `for_each_object_in_pack()`, the caller
`read_packs_list_from_stdin()` loops through each of the `include_packs`
and checks that its `->util` pointer (which is used to store the `struct
packed_git *` itself) is non-NULL.
This check is redundant, because `read_packs_list_from_stdin()` already
checks that the included packs are non-NULL earlier on in the same
function (and it does not add any new entries in between).
Remove this check, since it is not doing anything in the meantime.

Leakfix in the top-level called-once function.

commit: fix "author_ident" leak

When modifying the sparse-checkout definition, the sparse-checkout
builtin calls update_sparsity() to modify the SKIP_WORKTREE bits of all
cache entries in the index. Before, we needed the index to be fully
expanded in order to ensure we had the full list of files necessary that
match the new patterns.
Insert a call to reset_sparse_directories() that expands sparse
directories that are within the new pattern list, but only far enough
that every necessary file path now exists as a cache entry. The
remaining logic within update_sparsity() will modify the SKIP_WORKTREE
bits appropriately.
This allows us to disable command_requires_full_index within the
sparse-checkout builtin. Add tests that demonstrate that we are not
expanding to a full index unnecessarily.
We can see the improved performance in the p2000 test script:
Test HEAD~1 HEAD
------------------------------------------------------------------------
2000.24: git ... (sparse-v3) 2.14(1.55+0.58) 1.57(1.03+0.53) -26.6%
2000.25: git ... (sparse-v4) 2.20(1.62+0.57) 1.58(0.98+0.59) -28.2%
These reductions of 26-28% are small compared to most examples, but the
time is dominated by writing a new copy of the base repository to the
worktree and then deleting it again. The fact that the previous index
expansion was such a large portion of the time is telling how important
it is to complete this sparse index integration.

A future change will present a temporary, in-memory mode where the index
can both contain sparse directory entries but also not be completely
collapsed to the smallest possible sparse directories. This will be
necessary for modifying the sparse-checkout definition while using a
sparse index.
For now, convert the single-bit member 'sparse_index' in 'struct
index_state' to be a an 'enum sparse_index_mode' with three modes:
* INDEX_EXPANDED (0): No sparse directories exist. This is always the
case for repositories that do not use cone-mode sparse-checkout.
* INDEX_COLLAPSED: Sparse directories may exist. Files outside the
sparse-checkout cone are reduced to sparse directory entries whenever
possible.
* INDEX_PARTIALLY_SPARSE: Sparse directories may exist. Some file
entries outside the sparse-checkout cone may exist. Running
convert_to_sparse() may further reduce those files to sparse directory
entries.
The main reason to store this extra information is to allow
convert_to_sparse() to short-circuit when the index is already in
INDEX_EXPANDED mode but to actually do the necessary work when in
INDEX_PARTIALLY_SPARSE mode.
The INDEX_PARTIALLY_SPARSE mode will be used in an upcoming change.

The previous patch demonstrates a scenario where the list of packs
written by `pack-objects` (and stored in the `names` string_list) is
out-of-order, and can thus cause us to delete packs we shouldn't.
This patch resolves that bug by ensuring that `names` is sorted in all
cases, not just when
delete_redundant && pack_everything & ALL_INTO_ONE
is true.
Because we did sort `names` in that case (which, prior to `--geometric`
repacks, was the only time we would actually delete packs, this is only
a bug for `--geometric` repacks.
It would be sufficient to only sort `names` when `delete_redundant` is
set to a non-zero value. But sorting a small list of strings is cheap,
and it is defensive against future calls to `string_list_has_string()`
on this list.

Update 'repack' to ignore packs named on the command line with the
'--keep-pack' option. Specifically, modify 'init_pack_geometry()' to treat
command line-kept packs the same way it treats packs with an on-disk '.keep'
file (that is, skip the pack and do not include it in the 'geometry'
structure).
Without this handling, a '--keep-pack' pack would be included in the
'geometry' structure. If the pack is *before* the geometry split line (with
at least one other pack and/or loose objects present), 'repack' assumes the
pack's contents are "rolled up" into another pack via 'pack-objects'.
However, because the internally-invoked 'pack-objects' properly excludes
'--keep-pack' objects, any new pack it creates will not contain the kept
objects. Finally, 'repack' deletes the '--keep-pack' as "redundant" (since
it assumes 'pack-objects' created a new pack with its contents), resulting
in possible object loss and repository corruption.
Add a test ensuring that '--keep-pack' packs are now appropriately handled.

In c7c4bdeccf (run-command API: remove "env" member, always use
"env_array", 2021-11-25), there was a push to replace
cld.env = env->v;
with
strvec_pushv(&cld.env_array, env->v);
The conversion in c7c4bdeccf was mostly plug-and-play, with the snag
that some instances of strvec_pushv() became guarded with a NULL check
to ensure that the second argument was non-NULL.
This conversion was slightly over-eager to add a conditional in
builtin/receive-pack.c::unpack(), since we know at the point that we
add the result of `tmp_objdir_env()` into the child process's
environment, that `tmp_objdir` is non-NULL.
This follows from the conditional just before our strvec_pushv() call
(which returns from the function if `tmp_objdir` was NULL), as well as
the call to tmp_objdir_add_as_alternate() just below, which relies on
its argument (`tmp_objdir`) being non-NULL.
In the meantime, this extra conditional isn't hurting anything. But it
is redundant and thus unnecessarily confusing. So let's remove it.

When 7dce19d3 (fetch/pull: Add the --recurse-submodules option,
2010-11-12) introduced the "--recurse-submodule" option, the
approach taken was to perform fetches in submodules only once, after
all the main fetching (it may usually be a fetch from a single
remote, but it could be fetching from a group of remotes using
fetch_multiple()) succeeded. Later we added "--all" to fetch from
all defined remotes, which complicated things even more.
If your project has a submodule, and you try to run "git fetch
--recurse-submodule --all", you'd see a fetch for the top-level,
which invokes another fetch for the submodule, followed by another
fetch for the same submodule. All but the last fetch for the
submodule come from a "git fetch --recurse-submodules" subprocess
that is spawned via the fetch_multiple() interface for the remotes,
and the last fetch comes from the code at the end.
Because recursive fetching from submodules is done in each fetch for
the top-level in fetch_multiple(), the last fetch in the submodule
is redundant. It only matters when fetch_one() interacts with a
single remote at the top-level.
While we are at it, there is one optimization that exists in dealing
with a group of remote, but is missing when "--all" is used. In the
former, when the group turns out to be a group of one, instead of
spawning "git fetch" as a subprocess via the fetch_multiple()
interface, we use the normal fetch_one() code path. Do the same
when handing "--all", if it turns out that we have only one remote
defined.

Add a path_match_flags() function and have the two sets of
starts_with_dot_{,dot_}slash() functions added in
63e95beb085 (submodule: port resolve_relative_url from shell to C,
2016-04-15) and a2b26ffb1a8 (fsck: convert gitmodules url to URL
passed to curl, 2020-04-18) be thin wrappers for it.
As the latter of those notes the fsck version was copied from the
initial builtin/submodule--helper.c version.
Since the code added in a2b26ffb1a8 was doing really doing the same as
win32_is_dir_sep() added in 1cadad6f658 (git clone <url>
C:\cygwin\home\USER\repo' is working (again), 2018-12-15) let's move
the latter to git-compat-util.h is a is_xplatform_dir_sep(). We can
then call either it or the platform-specific is_dir_sep() from this
new function.
Let's likewise change code in various other places that was hardcoding
checks for "'/' || '\\'" with the new is_xplatform_dir_sep(). As can
be seen in those callers some of them still concern themselves with
':' (Mac OS classic?), but let's leave the question of whether that
should be consolidated for some other time.
As we expect to make wider use of the "native" case in the future,
define and use two starts_with_dot_{,dot_}slash_native() convenience
wrappers. This makes the diff in builtin/submodule--helper.c much
smaller.

This check was introduced in 8ee5d73137f (Fix fetch/pull when run without
--update-head-ok, 2008-10-13) in order to protect against replacing the ref
of the active branch by mistake, for example by running git fetch origin
master:master.
It was later extended in 8bc1f39f411 (fetch: protect branches checked out
in all worktrees, 2021-12-01) to scan all worktrees.
This operation is very expensive (takes about 30s in my repository) when
there are many tags or branches, and it is executed on every fetch, even if
no local heads are updated at all.
Limit it to protect only refs/heads/* to improve fetch performance.

Since 4c28e4ada03 (commit: die before asking to edit the log
message, 2010-12-20), we have been "leaking" the "author_ident" when
prepare_to_commit() fails. Instead of returning from right there,
introduce an exit status variable and jump to the clean-up label
at the end.
Instead of explicitly releasing the resource with strbuf_release(),
mark the variable with UNLEAK() at the end, together with two other
variables that are already marked as such. If this were in a
utility function that is called number of times, but these are
different, we should explicitly release resources that grow
proportionally to the size of the problem being solved, but
cmd_commit() is like main() and there is no point in spending extra
cycles to release individual pieces of resource at the end, just
before process exit will clean everything for us for free anyway.
This fixes a leak demonstrated by e.g. "t3505-cherry-pick-empty.sh",
but unfortunately we cannot mark it or other affected tests as passing
now with "TEST_PASSES_SANITIZE_LEAK=true" as we'll need to fix many
other memory leaks before doing so.
Incidentally there are two tests that always passes the leak checker
with or without this change. Mark them as such.
This is based on an earlier patch by Ævar, but takes a different
approach that is more maintainable.

Fix a bug in "git pull" where `submodule.recurse` is preferred over
`fetch.recurseSubmodules` when performing a fetch
(Documentation/config/fetch.txt says that `fetch.recurseSubmodules`
should be preferred.). Do this by passing the value of the
"--recurse-submodules" CLI option to the underlying fetch, instead of
passing a value that combines the CLI option and config variables.
In other words, this bug occurred because builtin/pull.c is conflating
two similar-sounding, but different concepts:
- Whether "git pull" itself should care about submodules e.g. whether it
should update the submodule worktrees after performing a merge.
- The value of "--recurse-submodules" to pass to the underlying "git
fetch".
Thus, when `submodule.recurse` is set, the underlying "git fetch" gets
invoked with "--recurse-submodules[=value]", overriding the value of
`fetch.recurseSubmodules`.
An alternative (and more obvious) approach to fix the bug would be to
teach "git pull" to understand `fetch.recurseSubmodules`, but the
proposed solution works better because:
- We don't maintain two identical config-parsing implementions in "git
pull" and "git fetch".
- It works better with other commands invoked by "git pull" e.g. "git
merge" won't accidentally respect `fetch.recurseSubmodules`.

Commit 73c6de06aff8 ("bisect: don't use invalid oid as rev when
starting") changes the behaviour of `git bisect` to consider invalid
oids as pathspecs again, as in the old shell implementation.
While that behaviour may be desirable, it can also cause confusion. For
example, while bisecting in a particular repo I encountered this:
$ git bisect start d93ff48803f0 v6.3
$
...which led to me sitting for a few moments, wondering why there's no
printout stating the first rev to check.
It turns out that the tag was actually "6.3", not "v6.3", and thus the
bisect was still silently started with only a bad rev, because
d93ff48803f0 was a valid oid and "v6.3" was silently considered to be a
pathspec.
While this behaviour may be desirable, it can be confusing, especially
with different repo conventions either using or not using "v" before
release names, or when a branch name or tag is simply misspelled on the
command line.
In order to avoid situations like this, make it more clear what we're
waiting for:
$ git bisect start d93ff48803f0 v6.3
status: waiting for good commit(s), bad commit known
We already have good output once the bisect process has begun in
earnest, so we don't need to do anything more there.

Update 'stash' to use 'merge_ort_nonrecursive()' to apply a stash to the
current working tree. When 'git stash apply' was converted from its shell
script implementation to a builtin in 8a0fc8d19d (stash: convert apply to
builtin, 2019-02-25), 'merge_recursive_generic()' was used to merge a stash
into the working tree as part of 'git stash (apply|pop)'. However, with the
single merge base used in 'do_apply_stash()', the commit wrapping done by
'merge_recursive_generic()' is not only unnecessary, but misleading (the
*real* merge base is labeled "constructed merge base"). Therefore, a
non-recursive merge of the working tree, stashed tree, and stash base tree
is more appropriate.
There are two options for a non-recursive merge-then-update-worktree
function: 'merge_trees()' and 'merge_ort_nonrecursive()'. Use
'merge_ort_nonrecursive()' to align with the default merge strategy used by
'git merge' (6a5fb96672 (Change default merge backend from recursive to ort,
2021-08-04)) and, because merge-ort does not operate in-place on the index,
avoid unnecessary index expansion. Update tests in 't1092' verifying index
expansion for 'git stash' accordingly.

Enable sparse index in 'git stash' by disabling
'command_requires_full_index'.
With sparse index enabled, some subcommands of 'stash' work without
expanding the index, e.g., 'git stash', 'git stash list', 'git stash drop',
etc. Others ensure the index is expanded either directly (as in the case of
'git stash [pop|apply]', where the call to 'merge_recursive_generic()' in
'do_apply_stash()' triggers the expansion), or in a command called
internally by stash (e.g., 'git update-index' in 'git stash -u'). So, in
addition to enabling sparse index, add tests to 't1092' demonstrating which
variants of 'git stash' expand the index, and which do not.
Finally, add the option to skip writing 'untracked.txt' in
'ensure_not_expanded', and use that option to successfully apply stashed
untracked files without a conflict in 'untracked.txt'.

Regression fix for 2.36 where "git name-rev" started to sometimes
reference strings after they are freed.
This fixes a regression in 2.36 and is slate to go to 2.36.1

"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".
This fixes a regression in 2.36 and is slate to go to 2.36.1

"git submodule update" without pathspec should silently skip an
uninitialized submodule, but it started to become noisy by mistake.
This fixes a regression in 2.36 and is slate to go to 2.36.1

The path taken by "git multi-pack-index" command from the end user
was compared with path internally prepared by the tool withut first
normalizing, which lead to duplicated paths not being noticed,
which has been corrected.
* ds/midx-normalize-pathname-before-comparison:
cache: use const char * for get_object_directory()
multi-pack-index: use --object-dir real path
midx: use real paths in lookup_multi_pack_index()

"git clone --origin X" leaked piece of memory that held value read
from the clone.defaultRemoteName configuration variable, which has
been plugged.

The remote_name variable is first assigned a copy of the value of
the "clone.defaultremotename" configuration variable and then by the
value of the "--origin" command line option. The former is prepared
to see multiple instances of the configuration variable by freeing
the current value of the variable before a copy of the newly
discovered value gets assigned to it. The latter however blindly
assigned a copy of the new value to the variable, thereby leaking
the value read from the configuration variable.

e900d494dc (diff: add an API for deferred freeing, 2021-02-11) added a
way to allow reusing diffopts: the no_free bit. 244c27242f (diff.[ch]:
have diff_free() call clear_pathspec(opts.pathspec), 2022-02-16) made
that mechanism mandatory.
git fast-export doesn't set no_free, so path limiting stopped working
after the first commit. Set the flag and add a basic test to make sure
only changes to the specified files are exported.

git format-patch only sets no_free when --output is given, causing it to
forget pathspecs after the first commit. Set no_free unconditionally
instead.
The existing test was unable to detect this breakage because it checks
stderr for the absence of a certain string, but format-patch writes to
stdout. Also the test was not checking the case of one commit modifying
multiple files and a pathspec limiting the diff. Replace it with a more
thorough one.
