Remove the "env" member from "struct child_process" in favor of always
using the "env_array". As with the preceding removal of "argv" in
favor of "args" this gets rid of current and future oddities around
memory management at the API boundary (see the amended API docs).
For some of the conversions we can replace patterns like:
child.env = env->v;
With:
strvec_pushv(&child.env_array, env->v);
But for others we need to guard the strvec_pushv() with a NULL check,
since we're not passing in the "v" member of a "struct strvec",
e.g. in the case of tmp_objdir_env()'s return value.
Ideally we'd rename the "env_array" member to simply "env" as a
follow-up, since it and "args" are now inconsistent in not having an
"_array" suffix, and seemingly without any good reason, unless we look
at the history of how they came to be.
But as we've currently got 122 in-tree hits for a "git grep env_array"
let's leave that for now (and possibly forever). Doing that rename
would be too disruptive.

Change a pattern of hardcoding an "argv" array size, populating it and
assigning to the "argv" member of "struct child_process" to instead
use "strvec_push()" to add data to the "args" member.
As noted in the preceding commit this moves us further towards being
able to remove the "argv" member in a subsequent commit
These callers could have used strvec_pushl(), but moving to
strvec_push() makes the diff easier to read, and keeps the arguments
aligned as before.

add_worktree() reuses a `child_process` for three run_command()
invocations, but to do so, it has overly-intimate knowledge of
run-command.c internals. In particular, it knows that it must reset
child_process::argv to NULL for each subsequent invocation[*] in order
for start_command() to latch the newly-populated child_process::args for
each invocation, even though this behavior is not a part of the
documented API. Beyond having overly-intimate knowledge of run-command.c
internals, the reuse of one `child_process` for three run_command()
invocations smells like an unnecessary micro-optimization. Therefore,
stop sharing one `child_process` and instead use a new one for each
run_command() call.
[*] If child_process::argv is not reset to NULL, then subsequent
run_command() invocations will instead incorrectly access a dangling
pointer to freed memory which had been allocated by child_process::args
on the previous run. This is due to the following code in
start_command():
if (!cmd->argv)
cmd->argv = cmd->args.v;

Currently, running 'git submodule deinit' on repos where the

Let's change this to instead warn the user that the .git/ directory

The rest of the deinit function can operate as it already does with
new-style submodules.
In one test, we used to require "git submodule deinit" to fail even

absorbed. Adjust it to expect the operation to pass.

The "checkout" command is one of the main sources of leaks in the test
suite, let's fix the common ones by not leaking from the "struct
branch_info".
Doing this is rather straightforward, albeit verbose, we need to
xstrdup() constant strings going into the struct, and free() the ones
we clobber as we go along.
This also means that we can delete previous partial leak fixes in this
area, i.e. the "path_to_free" accounting added by 96ec7b1e70 (Convert
resolve_ref+xstrdup to new resolve_refdup function, 2011-12-13).
There was some discussion about whether "we should retain the "const
char *" here and cast at free() time, or have it be a "char *". Since
this is not a public API with any sort of API boundary let's use
"char *", as is already being done for the "refname" member of the
same struct.
The tests to mark as passing were found with:
rm .prove; GIT_SKIP_TESTS=t0027 prove -j8 --state=save t[0-9]*.sh :: --immediate
# apply & compile this change
prove -j8 --state=failed :: --immediate
I.e. the ones that were newly passing when the --state=failed command
was run. I left out "t3040-subprojects-basic.sh" and
"t4131-apply-fake-ancestor.sh" to to optimization-level related
differences similar to the ones noted in[1], except that these would
be something the current 'linux-leaks' job would run into.

Regression fix.
* ab/fsck-unexpected-type:
object-file: free(*contents) only in read_loose_object() caller
object-file: fix SEGV on free() regression in v2.34.0-rc2
In the preceding commit a free() of uninitialized memory regression in
96e41f58fe (fsck: report invalid object type-path combinations,
2021-10-01) was fixed, but we'd still have an issue with leaking
memory from fsck_loose(). Let's fix that issue too.
That issue was introduced in my 31deb28f5e (fsck: don't hard die on
invalid object types, 2021-10-01). It can be reproduced under
SANITIZE=leak with the test I added in 093fffdfbe (fsck tests: add
test for fsck-ing an unknown type, 2021-10-01):
./t1450-fsck.sh --run=84 -vixd
In some sense it's not a problem, we lost the same amount of memory in
terms of things malloc'd and not free'd. It just moved from the "still
reachable" to "definitely lost" column in valgrind(1) nomenclature[1],
since we'd have die()'d before.
But now that we don't hard die() anymore in the library let's properly
free() it. Doing so makes this code much easier to follow, since we'll
now have one function owning the freeing of the "contents" variable,
not two.
For context on that memory management pattern the read_loose_object()
function was added in f6371f9210 (sha1_file: add read_loose_object()
function, 2017-01-13) and subsequently used in c68b489e56 (fsck:
parse loose object paths directly, 2017-01-13). The pattern of it
being the task of both sides to free() the memory has been there in
this form since its inception.

Before running the post-receive hook, status info is reported back to
the client. If a remote client exits before or during the status report,
receive-pack is killed by SIGPIPE and post-receive is never executed.
The post-receive hook is often used to send email notifications (see
contrib/hooks/post-receive-email), update bug trackers, start automatic
builds, etc. Not executing it after an interrupted yet "successful" push
can lead to inconsistencies.
Ignore SIGPIPE before reporting status to the client to increase the
chances of post-receive running if pre-receive was successful. This does
not guarantee 100% consistency but it should resist early disconnection

In eba1ba9 (maintenance: `git maintenance run` learned
`--scheduler=<scheduler>`, 2021-09-04), we introduced the ability to
specify a scheduler explicitly. This led to some extra checks around
whether an alternative scheduler was available. This added the
functionality of removing background maintenance from schedulers other
than the one selected.
On macOS, cron is technically available, but running 'crontab' triggers
a UI prompt asking for special permissions. This is the major reason why
launchctl is used as the default scheduler. The is_crontab_available()
method triggers this UI prompt, causing user disruption.
Remove this disruption by using an #ifdef to prevent running crontab
this way on macOS. This has the unfortunate downside that if a user
manually selects cron via the '--scheduler' option, then adjusting the
scheduler later will not remove the schedule from cron. The
'--scheduler' option ignores the is_available checks, which is how we
can get into this situation.
Extract the new check_crontab_process() method to avoid making the
'child' variable unused on macOS. The method is marked MAYBE_UNUSED
because it has no callers on macOS.

their ancestor, and this new error triggers.

to pull; we did the same historically with --ff-only, too.

`git repack` invokes a handful of child processes: one to write the
actual pack, and optionally ones to repack promisor objects and update
the MIDX.
Most of these are freed automatically by calling `start_command()` (which
invokes it on error) and `finish_command()` which calls it
automatically.
But repack_promisor_objects() can initialize a child_process, populate
its array of arguments, and then return from the function before even
calling start_command().
Make sure that the prepared list of arguments is freed by calling
child_process_clear() ourselves to avoid leaking memory along this path.

When constructing arguments to pass to setup_revision(), pack-objects
only frees the memory used by that array after calling
get_object_list().
Ensure that we call strvec_clear() whether or not we use the arguments
array by cleaning up whenever we exit the function (and rewriting one
early return to jump to a label which frees the memory and then
returns).
We could avoid setting this array up altogether unless we are in the
if-else block that calls get_object_list(), but setting up the argument
array is intermingled with lots of other side-effects, e.g.:
if (exclude_promisor_objects) {
use_internal_rev_list = 1;
fetch_if_missing = 0;
strvec_push(&rp, "--exclude-promisor-objects");
}
So it would be awkward to check exclude_promisor_objects twice: first to
set use_internal_rev_list and fetch_if_missing, and then again above
get_object_list() to push the relevant argument onto the array.
Instead, leave the array's construction alone and make sure to free it
unconditionally.

Change `update_index_from_diff` to set `skip-worktree` when applicable for
new index entries. When `git reset --mixed <tree-ish>` is run, entries in
the index with differences between the pre-reset HEAD and reset <tree-ish>
are identified and handled with `update_index_from_diff`. For each file, a
new cache entry in inserted into the index, created from the <tree-ish> side
of the reset (without changing the working tree). However, the newly-created
entry must have `skip-worktree` explicitly set in either of the following
scenarios:
1. the file is in the current index and has `skip-worktree` set
2. the file is not in the current index but is outside of a defined sparse
checkout definition
Not setting the `skip-worktree` bit leads to likely-undesirable results for
a user. It causes `skip-worktree` settings to disappear on the
"diff"-containing files (but *only* the diff-containing files), leading to
those files now showing modifications in `git status`. For example, when
running `git reset --mixed` in a sparse checkout, some file entries outside
of sparse checkout could show up as deleted, despite the user never deleting
anything (and not wanting them on-disk anyway).
Additionally, add a test to `t7102` to ensure `skip-worktree` is preserved
in a basic `git reset --mixed` scenario and update a failure-documenting
test from 19a0acc (t1092: test interesting sparse-checkout scenarios,

A refactoring[1] done as part of the recent conversion of
'git submodule add' to builtin, changed the error message
shown when a Git directory already exists locally for a submodule
name. Before the refactoring, the error used to appear like so:
--- START OF OUTPUT ---
$ git submodule add ../sub/ subm
A git directory for 'subm' is found locally with remote(s):
origin /me/git-repos-for-test/sub
If you want to reuse this local git directory instead of cloning again from
/me/git-repos-for-test/sub
use the '--force' option. If the local git directory is not the correct repo
or you are unsure what this means choose another name with the '--name' option.
--- END OF OUTPUT ---
After the refactoring the error started appearing like so:
--- START OF OUTPUT ---
$ git submodule add ../sub/ subm
A git directory for 'subm' is found locally with remote(s): origin /me/git-repos-for-test/sub
fatal: If you want to reuse this local git directory instead of cloning again from

use the '--force' option. If the local git directory is not the correct repo
or if you are unsure what this means, choose another name with the '--name' option.
--- END OF OUTPUT ---
As one could observe the remote information is printed along with the
first line rather than on its own line. Also, there's an additional
newline following output.
Make the error message consistent with the error message that used to be
printed before the refactoring.
This also moves the 'fatal:' prefix that appears in the middle of the
error message to the first line as it would more appropriate to have
it in the first line. The output after the change would look like:

fatal: A git directory for 'subm' is found locally with remote(s):
origin /me/git-repos-for-test/sub
If you want to reuse this local git directory instead of cloning again from
/me/git-repos-for-test/sub
use the '--force' option. If the local git directory is not the correct repo
or you are unsure what this means choose another name with the '--name' option.

When dwim_log() returns the "ref" is always ether NULL or an
xstrdup()'d string.

Add a missing strbuf_release() and a clear_pathspec() to the
submodule--helper.

At this point in cmd_clone the "git_dir" is always either an
xstrdup()'d string, or something we got from mkpathdup(). Let's free()
it before we clobber it.

Free the "path_list" used in builtin/grep.c, it was declared as
STRING_LIST_INIT_NODUP, let's change it to a STRING_LIST_INIT_DUP
since an early user in cmd_grep() appends a string passed via
parse-options.c to it, which needs to be duplicated.
Let's then convert the remaining callers to use
string_list_append_nodup() instead, allowing us to free the list.
This makes all the tests in t7811-grep-open.sh pass, 6/10 would fail
before this change. The only remaining failure would have been due to
a stray "git checkout" (which still leaks memory). In this case we can
use a "git reset --hard" instead, so let's do that, and move the
test_when_finished() above the code that would modify the relevant
file.

Free the "struct object_array" before exiting. This makes grep tests
(e.g. "t7815-grep-binary.sh") a bit happer under SANITIZE=leak.

Stylistically fix up code added in bfac23d953 (grep: Fix two memory
leaks, 2010-01-30). We usually don't use the "arg" at all once we've
casted it to the struct we want, let's not do that here when we're
freeing it. Perhaps it was thought that a cast to "void *" would
otherwise be needed?
