Now that the Perl "git-add--interactive" has gone away in the
preceding commit we don't need to pass along our desire for a mode as
a string, and can instead directly use the "enum add_p_mode", see
d2a233cb8b (built-in add -p: prepare for patch modes other than
"stage", 2019-12-21) for its introduction.
As a result of that the run_add_interactive() function would become a
trivial wrapper which would only run run_add_i() if a 0 (or now,
"NULL") "patch_mode" was provided. Let's instead remove it, and have
the one callsite that wanted the "NULL" case (interactive_add())
handle it.

Fix typos in code comments which repeat various words. Most of the
cases are simple in that they repeat a word that usually cannot be
repeated in a grammatically correct sentence. Just remove the
incorrectly duplicated word in these cases and rewrap text, if needed.
A tricky case is usage of "that that", which is sometimes grammatically
correct. However, an instance of this in "t7527-builtin-fsmonitor.sh"
doesn't need two words "that", because there is only one daemon being
discussed, so replace the second "that" with "the".

The "--super-prefix" option to "git" was initially added in [1] for
use with "ls-files"[2], and shortly thereafter "submodule--helper"[3]
and "grep"[4]. It wasn't until [5] that "read-tree" made use of it.
At the time [5] made sense, but since then we've made "ls-files"
recurse in-process in [6], "grep" in [7], and finally
"submodule--helper" in the preceding commits.
Let's also remove it from "read-tree", which allows us to remove the
option to "git" itself.
We can do this because the only remaining user of it is the submodule
API, which will now invoke "read-tree" with its new "--super-prefix"
option. It will only do so when the "submodule_move_head()" function
is called.
That "submodule_move_head()" function was then only invoked by
"read-tree" itself, but now rather than setting an environment
variable to pass "--super-prefix" between cmd_read_tree() we:
- Set a new "super_prefix" in "struct unpack_trees_options". The
"super_prefixed()" function in "unpack-trees.c" added in [5] will now
use this, rather than get_super_prefix() looking up the environment
variable we set earlier in the same process.
- Add the same field to the "struct checkout", which is only needed to
ferry the "super_prefix" in the "struct unpack_trees_options" all the
way down to the "entry.c" callers of "submodule_move_head()".
Those calls which used the super prefix all originated in
"cmd_read_tree()". The only other caller is the "unlink_entry()"
caller in "builtin/checkout.c", which now passes a "NULL".

tests: mark tests as passing with SANITIZE=leak
Fix various leaks in built-ins, libraries and a test helper here we
were missing a call to strbuf_release(), string_list_clear() etc, or
were calling them after a potential "return".
Comments on individual changes:
- builtin/checkout.c: Fix a memory leak that was introduced in [1]. A
sibling leak introduced in [2] was recently fixed in [3]. As with [3]
we should be using the wt_status_state_free_buffers() API introduced
in [4].
- builtin/repack.c: Fix a leak that's been here since this use of
"strbuf_release()" was added in a1bbc6c017 (repack: rewrite the shell
script in C, 2013-09-15). We don't use the variable for anything
except this loop, so we can instead free it right afterwards.
- builtin/rev-parse: Fix a leak that's been here since this code was
added in 21d4783538 (Add a parseopt mode to git-rev-parse to bring
parse-options to shell scripts., 2007-11-04).
- builtin/stash.c: Fix a couple of leaks that have been here since
this code was added in d4788af875 (stash: convert create to builtin,
2019-02-25), we strbuf_release()'d only some of the "struct strbuf" we
allocated earlier in the function, let's release all of them.
- ref-filter.c: Fix a leak in 482c119186 (gpg-interface: improve
interface for parsing tags, 2021-02-11), we don't use the "payload"
variable that we ask parse_signature() to populate for us, so let's
free it.
- t/helper/test-fake-ssh.c: Fix a leak that's been here since this
code was added in 3064d5a38c (mingw: fix t5601-clone.sh,
2016-01-27). Let's free the "struct strbuf" as soon as we don't need
it anymore.

Apply "index-compatibility.pending.cocci" rule to "builtin/*", but
exclude those where we conflict with in-flight changes.
As a result some of them end up using only "the_index", so let's have
them use the more narrow "USE_THE_INDEX_VARIABLE" rather than
"USE_THE_INDEX_COMPATIBILITY_MACROS".
Manual changes not made by coccinelle, that were squashed in:
* Whitespace-wrap argument lists for repo_hold_locked_index(),
repo_read_index_preload() and repo_refresh_and_write_index(), in cases
where the line became too long after the transformation.
* Change "refresh_cache()" to "refresh_index()" in a comment in
"builtin/update-index.c".

it to perror("<function-name>"), referring to the new function.

Mostly apply the part of "index-compatibility.pending.cocci" that
renames the global variables like "active_nr", which are a shorthand
to referencing (in that case) a struct member as "the_index.cache_nr".
In doing so move more of "index-compatibility.pending.cocci" to
"index-compatibility.cocci".
In the case of "active_nr" we'd have a textual conflict with
"ab/various-leak-fixes" in "next"[1]. Let's exclude that specific case
while moving the rule over from "pending".

Since 4aab5b46f4 (Make read-cache.c "the_index" free., 2007-04-01)
we've been undergoing a slow migration away from these macros, but
haven't made much progress since f8adbec9fe (cache.h: flip

Let's move forward a bit by changing the users of those macros that

As reported in [1] the "UNUSED(var)" macro introduced in
2174b8c75d (Merge branch 'jk/unused-annotation' into next,

it occurs.
Let's instead partially go with the approach suggested in [2] of
making this not take an argument. As noted in [1] "coccinelle" will
ignore such tokens in argument lists that it doesn't know about, and
it's less of a surprise to syntax highlighters.
This undoes the "help us notice when a parameter marked as unused is

"git checkout" miscounted the paths it updated, which has been

* mt/checkout-count-fix:
checkout: fix two bugs on the final count of updated entries
checkout: show bug about failed entries being included in final report
checkout: document bug where delayed checkout counts entries twice
At the end of `git checkout <pathspec>`, we get a message informing how
many entries were updated in the working tree. However, this number can
be inaccurate for two reasons:
1) Delayed entries currently get counted twice.
2) Failed entries are included in the count.
The first problem happens because the counter is first incremented
before inserting the entry in the delayed checkout queue, and once again
when finish_delayed_checkout() calls checkout_entry(). And the second
happens because the counter is incremented too early in
checkout_entry(), before the entry was in fact checked out. Fix that by
moving the count increment further down in the call stack and removing
the duplicate increment on delayed entries. Note that we have to keep
a per-entry reference for the counter (both on parallel checkout and
delayed checkout) because not all entries are always accumulated at the
same counter. See checkout_worktree(), at builtin/checkout.c for an
example.

In 1c41d2805e (unpack_trees_options: free messages when done,
2018-05-21) we started calling clear_unpack_trees_porcelain() on this
codepath, but missed this error path.
We could call clear_unpack_trees_porcelain() just before we error()
and return when unmerged_cache() fails, but the more correct fix is to
not have the unmerged_cache() check happen in the middle of our
"topts" setup.
Before 23cbf11b5c (merge-recursive: porcelain messages for checkout,
2010-08-11) we would not malloc() to setup our "topts", which is when
this started to leak on the error path.
Before that this code wasn't conflating the setup of "topts" and the
unmerged_cache() call in any meaningful way. The initial version in
782c2d65c2 (Build in checkout, 2008-02-07) just does a "memset" of
it, and initializes a single struct member.
Then in 8ccba008ee (unpack-trees: allow Porcelain to give different
error messages, 2008-05-17) we added the initialization of the error
message, which as noted above finally started leaking in 23cbf11b5c.
Let's fix the memory leak, and avoid future issues by initializing the
"topts" with a helper function. There are no functional changes here.

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.

Change the write_object_file() function to take an "enum object_type"
instead of a "const char *type". Its callers either passed
{commit,tree,blob,tag}_type and can pass the corresponding OBJ_* type
instead, or were hardcoding strings like "blob".
This avoids the back & forth fragility where the callers of
write_object_file() would have the enum type, and convert it
themselves via type_name(). We do have to now do that conversion
ourselves before calling write_object_file_prepare(), but those
codepaths will be similarly adjusted in subsequent commits.

When we taught these commands about the sparse index, we did not account
for the fact that the `cmd_*()` functions _can_ be called without a
gitdir, namely when `-h` is passed to show the usage.
A plausible approach to address this is to move the
`prepare_repo_settings()` calls right after the `parse_options()` calls:
The latter will never return when it handles `-h`, and therefore it is
safe to assume that we have a `gitdir` at that point, as long as the
built-in is marked with the `RUN_SETUP` flag.
However, it is unfortunately not that simple. In `cmd_pack_objects()`,
for example, the repo settings need to be fully populated so that the
command-line options `--sparse`/`--no-sparse` can override them, not the
other way round.
Therefore, we choose to imitate the strategy taken in `cmd_diff()`,
where we simply do not bother to prepare and initialize the repo
settings unless we have a `gitdir`.

Since some callers may want to send warning messages to somewhere other
than stdout/stderr, stop printing "warning: Cannot merge binary files"
from ll-merge and instead modify the return status of ll_merge() to
indicate when a merge of binary files has occurred. Message printing
probably does not belong in a "low-level merge" anyway.
This commit continues printing the message as-is, just from the callers
instead of within ll_merge(). Future changes will start handling the
message differently in the merge-ort codepath.
There was one special case here: the callers in rerere.c do NOT check
for and print such a message; since those code paths explicitly skip
over binary files, there is no reason to check for a return status of
LL_MERGE_BINARY_CONFLICT or print the related message.
Note that my methodology included first modifying ll_merge() to return
a struct, so that the compiler would catch all the callers for me and
ensure I had modified all of them. After modifying all of them, I then
changed the struct to an enum.

to ensure that a local branch is truly local and not a symref to
elsewhere that dies with BUG() otherwise. This was misguided in two
ways. First of all, such a tightening did not belong to a leak-fix
patch. And the condition it detected was *not* a bug in our program
but a problem in user data, where warning() or die() would have been
more appropriate.
As the condition is not fatal (the result of computing the local
branch name in the code that is involved in the faulty check is only
used as a textual label for the commit), let's revert the code to
the original state, i.e. strip "refs/heads/" to compute the local
branch name if possible, and otherwise leave it NULL. The consumer
of the information in merge_working_tree() is prepared to see NULL
in there and act accordingly.

"git branch -h" incorrectly said "--track[=direct|inherit]",
implying that "--trackinherit" is a valid option, which has been

branch,checkout: fix --track documentation
Document that the accepted variants of the --track option are --track,
--track=direct, and --track=inherit. The equal sign in the latter two
cannot be replaced with whitespace; in general optional arguments need
to be attached firmly to their option.
Put "direct" consistently before "inherit", if only for the reasons
that the former is the default, explained first in the documentation,
and comes before the latter alphabetically.
Mention both modes in the short help so that readers don't have to look
them up in the full documentation. They are literal strings and thus
untranslatable. PARSE_OPT_LITERAL_ARGHELP is inferred due to the pipe
and parenthesis characters, so we don't have to provide that flag
explicitly.
Mention that -t has the same effect as --track and --track=direct.
There is no way to specify inherit mode using the short option, because
short options generally don't accept optional arguments.

* js/branch-track-inherit:
branch,checkout: fix --track usage strings
As Ævar pointed out in [1], the use of PARSE_OPT_LITERAL_ARGHELP with a
list of allowed parameters is not recommended. Both git-branch and
git-checkout were changed in d311566 (branch: add flags and config to
inherit tracking, 2021-12-20) to use this discouraged combination for
their --track flags.
Fix this by removing PARSE_OPT_LITERAL_ARGHELP, and changing the arghelp
to simply be "mode". Users may discover allowed values in the manual
pages.

Move the running of the 'post-checkout' hook away from run-command.h
to the new hook.h library, except in the case of
builtin/worktree.c. That special-case will be handled in a subsequent
commit.

It can be helpful when creating a new branch to use the existing
tracking configuration from the branch point. However, there is
currently not a method to automatically do so.
Teach git-{branch,checkout,switch} an "inherit" argument to the
"--track" option. When this is set, creating a new branch will cause the
tracking configuration to default to the configuration of the branch
point, if set.
For example, if branch "main" tracks "origin/main", and we run
`git checkout --track=inherit -b feature main`, then branch "feature"
will track "origin/main". Thus, `git status` will show us how far
ahead/behind we are from origin, and `git pull` will pull from origin.
This is particularly useful when creating branches across many
submodules, such as with `git submodule foreach ...` (or if running with
a patch such as [1], which we use at $job), as it avoids having to
manually set tracking info for each submodule.
Since we've added an argument to "--track", also add "--track=direct" as
another way to explicitly get the original "--track" behavior ("--track"
without an argument still works as well).
Finally, teach branch.autoSetupMerge a new "inherit" option. When this
is set, "--track=inherit" becomes the default behavior.
