The previous patch made many lines a little longer, resulting in four
becoming a bit too long. They were left as-is for the previous patch
to facilitate reviewers verifying that we were just adding "internal."

Commit 2f6b1eb794 ("cache API: add a "INDEX_STATE_INIT" macro/function,
add release_index()", 2023-01-12) mistakenly added some initialization
of a member of unpack_trees_options that was intended to be
internal-only. This initialization should be done within
update_sparsity() instead.
Note that while o->result is mostly meant for unpack_trees() and
update_sparsity() mostly operates without o->result,
check_ok_to_remove() does consult it so we need to ensure it is properly
initialized.

struct unpack_trees_options has the following field and comment:
struct pattern_list *pl; /* for internal use */
Despite the internal-use comment, commit e091228e17 ("sparse-checkout:
update working directory in-process", 2019-11-21) starting setting this
field from an external caller. At the time, the only way around that
would have been to modify unpack_trees() to take an extra pattern_list
argument, and there's a lot of callers of that function. However, when
we split update_sparsity() off as a separate function, with
sparse-checkout being the sole caller, the need to update other callers
went away. Fix this API problem by adding a pattern_list argument to
update_sparsity() and stop setting the internal o.pl field directly.

The update_sparsity() function was introduced in commit 7af7a25853
("unpack-trees: add a new update_sparsity() function", 2020-03-27).
Prior to that, unpack_trees() was used, but that had a few bugs because
the needs of the caller were different, and different enough that
unpack_trees() could not easily be modified to handle both usecases.
The implementation detail that update_sparsity() was written by copying
unpack_trees() and then streamlining it, and then modifying it in the
needed ways still shows through in that there are leftover vestiges in
both functions that are no longer needed. Clean them up. In
particular:
* update_sparsity() allows a pattern list to be passed in, but
unpack_trees() never should use a different pattern list. Add a
check and a BUG() if this gets violated.
* update_sparsity() has a check early on that will BUG() if
o->skip_sparse_checkout is set; as such, there's no need to check
for that condition again later in the code. We can simply remove
the check and its corresponding goto label.

As evidenced by the fix a couple commits ago, places in the code using
exclude_per_dir are likely buggy and should be adapted to call
setup_standard_excludes() instead. Unfortunately, the usage of
exclude_per_dir has been hardcoded into the arguments ls-files accepts,
so we cannot actually remove it. Add a note that it is deprecated and
no other callers should use it directly.

When a directory exists but has only ignored files within it and we are
trying to switch to a branch that has a file where that directory is,
the behavior depends upon --[no]-overwrite-ignore. If the user wants to
--overwrite-ignore (the default), then we should delete the ignored file
and directory and switch to the new branch.
The code to handle this in verify_clean_subdirectory() in unpack-trees
tried to handle this via paying attention to the exclude_per_dir setting
of the internal dir field. This came from commit c81935348b ("Fix
switching to a branch with D/F when current branch has file D.",
2007-03-15), which pre-dated 039bc64e88 ("core.excludesfile clean-up",
2007-11-14), and thus did not pay attention to ignore patterns from
other relevant files. Change it to use setup_standard_excludes() so
that it is also aware of excludes specified in other locations.

t2021.6 existed to test the status of a symlink that was left around by
previous tests. It tried to also clean up the symlink after it was done
so that subsequent tests wouldn't be tripped up by it. Unfortunately,
since this test had a SYMLINK prerequisite, that made the cleanup
platform dependent...and made a testcase I was trying to add to this
testsuite fail (that testcase will be included in the next patch).
Before we go and add new testcases, fix this cleanup by moving it into a

Commit fd2d4c135e (gpg-interface: lazily initialize and read the
configuration, 2023-02-09) shrunk a few custom config callbacks so that
they are just one-liners of:
return git_default_config(...);
We can drop them entirely and replace them direct calls of
git_default_config() intead. This makes the code a little shorter and
easier to understand (with the downside being that if they do grow
custom options again later, we'll have to recreate the functions).

In fb64ca526a (fsck: check index files in all worktrees, 2023-02-24), we
swapped out a call to vanilla repo_read_index() for a series of
read_index_from() calls, one per worktree. The code for the latter was
copied from add_index_objects_to_pending(), which checks for a positive
return value from the index reading function, and we do the same here in
fsck now.
But this is probably the wrong thing. I had interpreted the check as
"don't operate on the index struct if there was an error". But in
reality, if there is an error then the index-reading code will simply
die (which admittedly is not great for fsck, but that is not a new
problem).
The return value here is actually the number of entries read. So it
makes sense for add_index_objects_to_pending() to ignore a zero-entry
index (there is nothing to add). But for fsck, we would still want to
check any extensions, etc (though presumably it is unlikely to have them
in an empty index, I don't think it's impossible).
So we should ignore the return value from read_index_from() entirely.
This matches the behavior before fb64ca526a, when we ignored the return
value from repo_read_index().

In 8d9fdd7 (worktree.c: check whether branch is rebased in another
worktree, 2016-04-22) die_if_checked_out() learned a new option
ignore_current_worktree, to modify the operation from "die() if the
branch is checked out in any worktree" to "die() if the branch is
checked out in any worktree other than the current one".
Unfortunately we implemented it by checking the flag is_current in the
worktree that find_shared_symref() returns.
When the same branch is checked out in several worktrees simultaneously,
find_shared_symref() will return the first matching worktree in the list
composed by get_worktrees(). If one of the worktrees with the checked
out branch is the current worktree, find_shared_symref() may or may not
return it, depending on the order in the list.
Instead of find_shared_symref(), let's do the search using use the
recently introduced API is_shared_symref(), and consider
ignore_current_worktree when necessary.

If we encounter an error in an index file, we may say something like:
error: 1234abcd: invalid sha1 pointer in resolve-undo
But if you have multiple worktrees, each with its own index, it can be
very helpful to know which file had the problem. So let's pass that path
down through the various index-fsck functions and use it where
appropriate. After this patch you should get something like:
error: 1234abcd: invalid sha1 pointer in resolve-undo of .git/worktrees/wt/index
That's a bit verbose, but since the point is that you shouldn't see this
normally, we're better to err on the side of more details.
I've also added the index filename to the name used by "fsck
--name-objects", which will show up if we find the object to be missing,
etc. This is bending the rules a little there, as the option claims to
write names that can be fed to rev-parse. But there is no revision
syntax to access the index of another worktree, so the best we can do is
make up something that a human will probably understand.
I did take care to retain the existing ":file" syntax for the current
worktree. So the uglier output should kick in only when it's actually
necessary. See the included tests for examples of both forms.

We check the index file for the main worktree, but completely ignore the
index files in other worktrees. These should be checked, too, as they

The code to fsck an index operates directly on the_index. Let's move it
into its own function in preparation for handling the index files from
other worktrees.
Since we now have only a single reference to the_index, let's drop
our USE_THE_INDEX_VARIABLE definition and just use the_repository.index
directly. That's a minor cleanup, but also ensures that we didn't miss
any references when moving the code into fsck_index().

After forking but before exec-ing a command, we install special
error/warn/die handlers in the child. These ignore the error messages
they get, since the idea is that they shouldn't be called in the first
place.
Arguably they could pass along that error message _in addition_ to
saying "error() should not be called in a child", but since the whole
point is to avoid any conflicts on stdio/malloc locks, etc, we're better
to just keep these simple. Seeing them trigger is effectively a bug, and
the developer is probably better off grabbing a stack trace.

Both the object_array_filter() and trie_find() functions use callback
functions that let the caller specify which elements match. These
callbacks take a void pointer in case the caller wants to pass in extra
data. But in each case, the single user of these functions just passes
NULL, and the callback ignores the extra pointer.
We could just remove these unused parameters from the callback interface
entirely. But it's good practice to provide such a pointer, as it guides
future callers of the function in the right direction (rather than
tempting them to access global data). Plus it's consistent with other
generic callback interfaces.
So let's instead annotate the unused parameters, in order to silence the
compiler's -Wunused-parameter warning.

The ref-filter code uses virtual functions to handle specific atoms, but
many of the functions ignore some parameters:
- most atom parsers do not need the ref_format itself, unless they are
looking at centralized options like use_color, quote_style, etc.
- meta-atom handlers like append_atom(), align_atom_handler(), etc,
can't generate errors, so ignore their "err" parameter
- likewise, the handlers for then/else/end do not even need to look at
their atom_value, as the "if" handler put everything they need into
the ref_formatting_state stack
Since these functions all have to conform to virtual function
interfaces, we can't just drop the unused parameters, but must mark them

We can't drop them because it's cmd_main(), which has a set prototype,
but the CGI interface does not do anything with such arguments.
Arguably we could detect them and complain. It's possible this could
detect misconfigurations or other mistakes, but:
- as far as I can tell common webservers like apache do not have any
mechanism to pass arguments to a CGI at all, so this isn't a mistake
one could even make
- it's possible that some obscure webserver might pass arguments, and
we'd break that case. I have no idea if such a webserver exists; the
CGI standard says only "The script is invoked in a system-defined
manner".
So probably it would not hurt to detect them, but it also is unlikely to
help anyone. Let's just mark them as unused, which retains the current

The object-name disambiguation code triggers a callback for each
possible object id we find. This is really used for two purposes:
- "hint" functions like disambiguate_commit_only report back on
whether the value is usable
- iterator functions like repo_for_each_abbrev() use it to collect
and report matching names.
Compiling with -Wunused-parameter generates several warnings, but
they're distinct for each type. The "hint" functions never look at the
void cb_data pointer; they only care whether the oid matches our hint.
The iterator functions never look at the "struct repository" parameter;
they're just reporting back the oids they see, and always return 0.
So arguably these could be two separate interfaces:
int (*hint)(struct repository *r, const struct object_id *oid);
void (*iter)(const struct object_id *oid, void *cb_data);
But doing so would complicate the disambiguation code, which now has to
accept and call the two different types. Since we can easily squelch the
compiler warnings by annotating the functions, let's just do that.

Each v2 "serve" action has a virtual function for advertising and
implementing the command. A few of these are so trivial that they don't
need to look at their parameters, especially the "repository" parameter.
We can mark them so that -Wunused-parameter doesn't complain.
Note that upload_pack_v2() probably _should_ be using its repository
pointer. But teaching the functions it calls to do so is non-trivial.
Even using it for something as simple as reading config is tricky, both
because it shares code with the v1 upload pack, and because the
git_protected_config() mechanism it uses does not have a repo-specific
interface. So we'll just annotate it for now, and cleaning it up can be

A few of the v2 "serve" callbacks ignore their repository parameter and
read config using the_repository (either directly or implicitly by
calling wrapper functions). This isn't a bug since the server code only
handles a single main repository anyway (and indeed, if you look at the
callers, these repository parameters will always be the_repository). But
in the long run we want to get rid of the_repository, so let's take a
tiny step in that direction.

The code for the v2 ls-refs command has an ensure_config_read() function
that tries to read the lsrefs.unborn config only once and caches it in
some static global variables.
There's no real need for this caching. In any given process we'd only
need the value twice (once to decide whether to advertise, and once if
somebody runs the command). And since the config code already has its
own cache, each access is only incurring a hash lookup and string
comparison anyway.
Since the values we set are going to be specific to the_repository, the
globals we set are a mild anti-pattern. In practice it's not a bug (yet)
since the server-side v2 code only handles a single repository anyway.
But it doesn't hurt to take a small step in the right direction and
model a good approach.
Note that we currently set two booleans: advertise_unborn and
allow_unborn. But we can get away with a single value, since "advertise"
naturally implies "allow". That lets us just convert this to a function
with a return value.
Note that we still always read from the_repository; we'll deal with that
in a follow-on patch.
