The 'git sparse-checkout clean' subcommand is focused on directories,
deleting any tracked sparse directories to clean up the worktree and
make the sparse index feature work optimally.
However, this directory-focused approach can leave users wondering why
those directories exist at all. In my experience, these files are left
over due to ignore or exclude patterns, Windows file handles, or
possibly merge conflict resolutions.
Add a new '--verbose' option for users to see all the files that are
being deleted (with '--force') or would be deleted (with '--dry-run').
Based on usage, users may request further context on this list of files for
states such as tracked/untracked, unstaged/staged/conflicted, etc.

The 'git sparse-checkout clean' subcommand is somewhat similar to 'git
clean' in that it will delete files that should not be in the worktree.
The big difference is that it focuses on the directories that should not
be in the worktree due to cone-mode sparse-checkout. It also does not
discriminate in the kinds of files and focuses on deleting entire
directories.
However, there are some restrictions that would be good to bring over
from 'git clean', specifically how it refuses to do anything without the
'-f'/'--force' or '-n'/'--dry-run' arguments. The 'clean.requireForce'
config can be set to 'false' to imply '--force'.
Add this behavior to avoid accidental deletion of files that cannot be
recovered from Git.

When users change their sparse-checkout definitions to add new
directories and remove old ones, there may be a few reasons why
directories no longer in scope remain (ignored or excluded files still
exist, Windows handles are still open, etc.). When these files still
exist, the sparse index feature notices that a tracked, but sparse,
directory still exists on disk and thus the index expands. This causes a
performance hit _and_ the advice printed isn't very helpful. Using 'git
clean' isn't enough (generally '-dfx' may be needed) but also this may
not be sufficient.
Add a new subcommand to 'git sparse-checkout' that removes these
tracked-but-sparse directories.
The implementation details provide a clear definition of what is happening,
but it is difficult to describe this without including the internal
implementation details. The core operation converts the index to a sparse
index (in memory if not already on disk) and then deletes any directories in
the worktree that correspond with a sparse directory entry in that sparse
index.
In the most common case, this means that a file will be removed if it is
contained within a directory that is both tracked and outside of the
sparse-checkout definition. However, there can be exceptions depending on
the current state of the index:
* If the worktree has a modification to a tracked, sparse file, then that
file's parent directories will be expanded instead of represented as
sparse directories. Siblings of those parent directories may be
considered sparse.
* If the user staged a sparse file with "git add --sparse", then that file
loses the SKIP_WORKTREE bit until the sparse-checkout is reapplied. Until
then, that file's parent directories are not represented as sparse
directory entries and thus will not be removed. Siblings of those parent
directories may be considered sparse. (There may be other reasons why
the SKIP_WORKTREE bit was removed for a file and this impact on the
sparse directories will apply to those as well.)
* If the user has a merge conflict outside of the sparse-checkout
definition, then those conflict entries prevent the parent directories
from being represented as sparse directory entries and thus are not
removed.
* The cases above present reasons why certain _file conditions_ will impact
which _directories_ are considered sparse. The list of tracked
directories that are outside of the sparse-checkout definition but not
represented as a sparse directory further reduces the list of files that
will be removed.
For these complicated reasons, the documentation details a potential list of
files that will be "considered for removal" instead of defining the list
concretely. The special cases can be handled by resolving conflicts,
committing staged changes, and running 'git sparse-checkout reapply' to
update the SKIP_WORKTREE bits as expected by the sparse-checkout definition.
It is important to make clear that this operation will remove ignored and
excluded files which would normally be ignored even by 'git clean -f' unless
the '-x' or '-X' option is provided. This is the most extreme method for
doing this, but it works when the sparse-checkout is in cone mode and is
expected to rescope based on directories, not files.
The current implementation always deletes these sparse directories
without warning. This is unacceptable for a released version, but those
features will be added in changes coming immediately after this one.
Note that this will not remove an untracked directory (or any of its
contents) if its parent is a tracked directory within the sparse-checkout
definition. This is required to prevent removing data created by tools that
perform caching operations for editors or build tools.
Thus, 'git sparse-checkout clean' is both more aggressive and more careful
than 'git clean -fx':
* It is more aggressive because it will remove _tracked_ files within the
sparse directories.
* It is less aggressive because it will leave _untracked_ files that are
not contained in sparse directories.
These special cases will be handled more explicitly in a future change that
expands tests for the 'git sparse-checkout clean' command. We handle some of
the modified, staged, and committed states including some impact on 'git
status' after cleaning.

The logic for the 'git sparse-checkout' builtin uses the_repository all
over the place, despite some use of a repository struct in different
method parameters. Complete this removal of the_repository by using
'repo' when possible.
In one place, there was already a local variable 'r' that was set to
the_repository, so move that to a method parameter.
We cannot remove the USE_THE_REPOSITORY_VARIABLE declaration as we are
still using global constants for the state of the sparse-checkout.

In 036876a1067 (config: hide functions using `the_repository` by
default, 2024-08-13) we have moved around a bunch of functions in the
config subsystem that depend on `the_repository`. Those function have
been converted into mere wrappers around their equivalent function that
takes in a repository as parameter, and the intent was that we'll
eventually remove those wrappers to make the dependency on the global
repository variable explicit at the callsite.
Follow through with that intent and remove `git_config()`. All callsites
are adjusted so that they use `repo_config(the_repository, ...)`
instead. While some callsites might already have a repository available,
this mechanical conversion is the exact same as the current situation
and thus cannot cause any regression. Those sites should eventually be
cleaned up in a later patch series.

The `safe_create_leading_directories()` function and its relatives are
located in "object-file.c", which is not a good fit as they provide
generic functionality not related to objects at all. Move them into
"path.c", which already hosts `safe_create_dir()` and its relative
`safe_create_dir_in_gitdir()`.
"path.c" is free of `the_repository`, but the moved functions depend on
`the_repository` to read the "core.sharedRepository" config. Adapt the
function signature to accept a repository as argument to fix the issue
and adjust callers accordingly.

In 9b1cb5070f (builtin: add a repository parameter for builtin

commands. This allowed the repository to be passed down to lower layers
without depending on the global `the_repository` variable.
Continue this work by also passing down the repository parameter from
the command to sub-commands. This will help pass down the repository to
other subsystems and cleanup usage of global variables like
'the_repository' and 'the_hash_algo'.

Both `git sparse-checkout add` and `git sparse-checkout set` accept a
list of additional directories or patterns. These get massaged via calls
to `sanitize_paths()`, which may end up modifying the passed-in array by
updating its pointers to be prefixed paths. This allocates memory that
we never free.
Refactor the code to instead use a `struct strvec`, which makes it way
easier for us to track the lifetime correctly. The couple of extra
memory allocations likely do not matter as we only ever populate it with
command line arguments.

When "git sparse-checkout disable" turns a sparse checkout into a

When running 'git sparse-checkout disable' with the sparse index

for doing a similar removal in the future.

When updating sparse patterns, we open a lock_file to write out the new
data. The lock_file struct holds the file descriptor, but we call
fdopen() to get a stdio handle to do the actual write.
After we finish writing, we fflush() so that all of the data is on disk,
and then call commit_lock_file() which closes the descriptor. But we
never fclose() the stdio handle, leaking it.
The obvious solution seems like it would be to just call fclose(). But
when? If we do it before commit_lock_file(), then the lock_file code is
left thinking it owns the now-closed file descriptor, and will do an
extra close() on the descriptor. But if we do it before, we have the
opposite problem: the lock_file code will close the descriptor, and
fclose() will do the extra close().
We can handle this correctly by using fdopen_lock_file(). That leaves
ownership of the stdio handle with the lock_file, which knows not to
double-close it.
We do have to adjust the code a bit:
- we have to handle errors ourselves; we can just die(), since that's
what xfdopen() would have done (and we can even provide a more
specific error message).
- we no longer need to call fflush(); committing the lock-file
auto-closes it, which will now do the flush for us. As a bonus, this
will actually check that the flush was successful before renaming
the file into place.
- we can get rid of the local "fd" variable, since we never look at it
ourselves now

When writing a new "sparse-checkout" file, we do the usual strategy of
writing to a lockfile and committing it into place. But we don't check
the outcome of commit_lock_file(). Failing there would prevent us from
writing a bogus file (good), but we would ignore the error and return a
successful exit code (bad).
Fix this by calling die(). Note that we need to keep the sparse_filename
variable valid for longer, since the filename stored in the lock_file
struct will be dropped when we run commit_lock_file().

In insert_recursive_pattern(), we create a new pattern_entry to insert
into the parent_hashmap. If we find that the same entry already exists
in the hashmap, we skip adding the new one. But we forget to free the new
one, creating a leak.
We can fix it by cleaning up the discarded entry. It would probably be
possible to avoid creating it in the first place, but it's non-trivial.
We'd have to define a "keydata" struct that lets us compare the existing
entries to the broken-out fields. It's probably not worth the
complexity, so we'll punt on that for now.
There is one subtlety here: our insertion is happening in a loop, with
each iteration looking at the pattern we just inserted (hence the
"recursive" in the name). So if we skip insertion, what do we look at?
The obvious answer is that we should remember the existing duplicate we
found and use that. But I _think_ in that case, we probably already have
all of the recursive bits already (from when the original entry was
added). And so just breaking out of the loop would be correct. But I'm
not 100% sure on that; after all, the original leaky code could have
done the same break, but it didn't.
So I went with the "obvious answer" above, which has no chance of
changing the behavior aside from fixing the leak.
With this patch, t1091 can now be marked leak-free.

In sparse_checkout_list(), we create a pattern_list that needs to
eventually be cleared. We remember to do so in the regular code path,
but the cone-mode path does an early return, and forgets to clean up.
We could fix the leak by adding a new call to clear_pattern_list(). But
we can simplify even further by just skipping the early return, pushing
the other code path (which consists now of only one line!) into an else
block. That also matches the same cone/non-cone if/else used in some
other functions.
This fixes 15 leaks found in t1091.

In update_working_directory(), we take in a pattern_list, attach it to
the repository index by assigning it to index->sparse_checkout_patterns,
and then call unpack_trees. Afterwards, we remove it by setting
index->sparse_checkout_patterns back to NULL.
But there are two possible leaks here:
1. If the index already had a populated sparse_checkout_patterns,
we've obliterated it. We can fix this by saving and restoring it,
rather than always setting it back to NULL.
2. We may call the function with a NULL pattern_list, expecting it to
use the on-disk sparse file. In that case, the index routines will
lazy-load the sparse patterns automatically. But now at the end of
the function when we restore the patterns, we'll leak those
lazy-loaded ones!
We can fix this by freeing the pattern list before overwriting its
pointer whenever it does not match what was passed in (in practice
this should only happen when the passed-in list is NULL, but this
is erring on the defensive side).
Together these remove 48 indirect leaks found in t1091.

In add_patterns_from_input(), we may read lines from a file with a loop
like this:
while (!strbuf_getline(&line, file)) {
...
strbuf_to_cone_pattern(&line, pl);
}
/* we don't strbuf_release(&line) here! */
This generally is OK because strbuf_to_cone_pattern() consumes the
buffer via strbuf_detach(). But we can leak in a few cases:
1. We don't always consume the buffer! If the line ends up empty after
trimming, we leave strbuf_to_cone_pattern() without detaching. In
most cases this is OK, because a subsequent getline() call will use
the same buffer. But if you had an empty line at the end of file,
for example, it would leak.
2. Even if strbuf_to_cone_pattern() always consumed the buffer,
there's a subtle issue with strbuf_getline(). As we saw in
94e2aa555e (strbuf: fix leak when `appendwholeline()` fails with
EOF, 2024-05-27), it's possible for it to return EOF with an
allocated buffer (e.g., if the underlying getdelim() call saw an
error). So we should always strbuf_release() after finishing a read
loop like this.
Note that even the code to read patterns from argv has the same problem.
Because that also uses strbuf_to_cone_pattern(), we stuff each argv
entry into a strbuf. It uses the same "line" strbuf as the getline code,
but we should position the strbuf_release() to cover both code paths.
This fixes at least 9 leaks found in t1091.

When we read patterns from --stdin, we loop on strbuf_getline(), and
detach each line we read to pass into add_pattern(). This used to be
necessary because add_pattern() required that the pattern strings remain
valid while the pattern_list was in use. But it also created a leak,
since we didn't record the detached buffers anywhere else.
Now that add_pattern() has been modified to make its own copy of the
strings, we can stop detaching and fix the leak. This fixes 4 leaks

In sparse_checkout_init(), we first try to load patterns from an
existing file. If we found any, we return immediately, but end up
leaking the patterns we parsed. Fixing this reduces the number of leaks
in t7002 from 9 down to 5.
Note that there are two other exits from the function, but they don't
need the same treatment:
- if we can't resolve HEAD, we write out a hard-coded sparse file and
return. But we know the pattern list is empty there, since we didn't
find any in the on-disk file and we haven't yet added any of our
own.
- otherwise, we do populate the list and then tail-call into
write_patterns_and_update(). But that function frees the
pattern_list itself, so we don't need to.

The add_pattern() function takes a pattern string, but neither makes a
copy of it nor takes ownership of the memory. So it is the caller's
responsibility to make sure the string hangs around as long as the
pattern_list which references it.
There are a few cases in sparse-checkout where we use string literal
patterns by stuffing them into a strbuf, detaching the buffer, and then
passing the result into add_pattern(). This creates a leak when the
pattern_list is eventually cleared, since we don't retain a copy of the
detached buffer to free.
But we can observe that the whole strbuf dance is unnecessary. The point
was presumably[1] to satisfy the lifetime requirement of the string. But
string literals have static duration; we can count on them lasting for
the whole program.
So we can fix the leak by just passing them directly. And as a bonus,
that simplifies the code. The leaks can be seen in t7002, which drops
from 25 leaks to 22 with this patch. It also makes t3602 and t1090
leak-free.
In the long run, we will also want to clean up this (undocumented!)
memory lifetime requirement of add_pattern(). But that can come in a
later patch; passing the string literals directly will be the right
thing either way.

93851746 (parse-options: decouple "--end-of-options" and "--",
2023-12-06) updated the world order to make callers of parse-options
that set PARSE_OPT_KEEP_UNKNOWN_OPT responsible for deciding what to
do with "--end-of-options" they may see after parse_options() returns.
This made a previous bug in sparse-checkout more visible; namely,
that
git sparse-checkout [add|set] --[no-]cone --end-of-options ...
would simply treat "--end-of-options" as one of the paths to include in
the sparse-checkout. But this was already problematic before; namely,
git sparse-checkout [add|set| --[no-]cone --sikp-checks ...
would not give an error on the mis-typed "--skip-checks" but instead
simply treat "--sikp-checks" as a path or pattern to include in the
sparse-checkout, which is highly unfriendly.
This behavior began when the command was converted to parse-options in
7bffca95ea (sparse-checkout: add '--stdin' option to set subcommand,
2019-11-21). Back then it was just called KEEP_UNKNOWN. Later it was
renamed to KEEP_UNKNOWN_OPT in 99d86d60e5 (parse-options:
PARSE_OPT_KEEP_UNKNOWN only applies to --options, 2022-08-19) to clarify
that it was only about dashed options; we always keep non-option
arguments. Looking at that original patch, both Peff and I think that
the author was simply confused about the mis-named option, and really
just wanted to keep the non-option arguments. We never should have used
the flag all along (and the other cases were cargo-culted within the
file).
Remove the erroneous PARSE_OPT_KEEP_UNKNOWN_OPT flag now to fix this
bug. Note that this does mean that anyone who might have been using
git sparse-checkout [add|set] [--[no-]cone] --foo --bar
to request paths or patterns '--foo' and '--bar' will now have to use
git sparse-checkout [add|set] [--[no-]cone] -- --foo --bar
That makes sparse-checkout more consistent with other git commands,
provides users much friendlier error messages and behavior, and is
consistent with the all-caps warning in git-sparse-checkout.txt that
this command "is experimental...its behavior...will likely change". :-)

of git-compat-util.h (or a short-list of alternate headers that happen
to include it first). This change exposed the violation and caused it
to stop building correctly; fix it by having it include
git-compat-util.h first, as per policy.

There exists no direct way to interrogate git about which paths are
matched by a given set of sparsity rules. It is possible to get this
information from git, but it includes checking out the commit that
contains the paths, applying the sparse checkout patterns and then using
something like 'git ls-files -t' to check if the skip worktree bit is
set. This works in some case, but there are cases where it is awkward or
infeasible to generate a checkout for this purpose.
Exposing the pattern matching of sparse checkout enables more tooling to
be built and avoids a situation where tools that want to reason about
sparse checkouts start containing parallel implementation of the rules.
To accommodate this, add a 'check-rules' subcommand to the
'sparse-checkout' builtin along the lines of the 'git check-ignore' and
'git check-attr' commands. The new command accepts a list of paths on
stdin and outputs just the ones the match the sparse checkout.
To allow for use in a bare repository and to allow for interrogating
about other patterns than the current ones, include a '--rules-file'
option which allows the caller to explicitly pass sparse checkout rules
in the format accepted by 'sparse-checkout set --stdin'.
To allow for reuse of the handling of input patterns for the
'--rules-file' flag, modify 'add_patterns_from_input()' to be able to
read from a 'FILE' instead of just stdin.
To allow for reuse of the logic which decides whether or not rules
should be interpreted as cone-mode patterns, split that part out of
'update_modes()' such that can be called without modifying the config.
An alternative could have been to create a new 'check-sparsity' command.
However, placing it under 'sparse-checkout' allows for a) more easily
re-using the sparse checkout pattern matching and cone/non-code mode
handling, and b) keeps the documentation for the command next to the
experimental warning and the cone-mode discussion.

In preparation for adding a sub-command to 'sparse-checkout' that can be
run in a bare repository, remove the 'NEED_WORK_TREE' flag from its
entry in the 'commands' array of 'git.c'.
To avoid that this changes any behaviour, add calls to
'setup_work_tree()' to all of the 'sparse-checkout' sub-commands and add
tests that verify that 'sparse-checkout <cmd>' still fail with a clear
error message telling the user that the command needs a work tree.

Dozens of files made use of gettext functions, without explicitly
including gettext.h. This made it more difficult to find which files
could remove a dependence on cache.h. Make C files explicitly include
gettext.h if they are using it.
However, while compat/fsmonitor/fsm-ipc-darwin.c should also gain an
include of gettext.h, it was left out to avoid conflicting with an
in-flight topic.

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.
