Unless `command_requires_full_index` forces index expansion, ensure in-core
index sparsity matches config settings on read by calling
`ensure_correct_sparsity`. This makes the behavior of the in-core index more
consistent between different methods of updating sparsity: manually changing
the `index.sparse` config setting vs. executing
`git sparse-checkout --[no-]sparse-index init`
Although index sparsity is normally updated with `git sparse-checkout init`,
ensuring correct sparsity after a manual `index.sparse` change has some
practical benefits:
1. It allows for command-by-command sparsity toggling with
`-c index.sparse=<true|false>`, e.g. when troubleshooting issues with the
sparse index.
2. It prevents users from experiencing abnormal slowness after setting
`index.sparse` to `true` due to use of a full index in all commands until
the on-disk index is updated.

This causes several failures for GPGSSH tests. We fulfill the

verifying a signature causes results ranging from bogus results to
ssh-keygen segfaulting.
We can find the broken version during the prereq check by feeding it

* ad/ssh-signing-testfix:
t/lib-git.sh: fix ACL-related permissions failure
As well as checking that the relevant functionality is available, the
GPGSSH prerequisite check creates the SSH keys that are used by the test
functions it gates. If these keys are created in a directory that
has a default Access Control List, the key files can inherit those
permissions.
This can result in a scenario where the private keys are created
successfully, so the prerequisite check passes and the tests are run,
but the key files have permissions that are too permissive, meaning
OpenSSH will refuse to load them and the tests will fail.
To avoid this happening, before creating the keys, clear any default ACL
set on the directory that will contain them. This step allowed to fail;
if setfacl isn't present, that's a very likely indicator that the
filesystem in question simply doesn't support default ACLs.

The strftime() function has a non-standard "%s" extension, which prints
the number of seconds since the epoch. But the "struct tm" we get has
already been adjusted for a particular time zone; going back to an epoch
time requires knowing that zone offset. Since strftime() doesn't take
such an argument, round-tripping to a "struct tm" and back to the "%s"
format may produce the wrong value (off by tz_offset seconds).
Since we're already passing in the zone offset courtesy of c3fbf81a85
(strbuf: let strbuf_addftime handle %z and %Z itself, 2017-06-15), we
can use that same value to adjust our epoch seconds accordingly.
Note that the description above makes it sound like strftime()'s "%s" is
useless (and really, the issue is shared by mktime(), which is what
strftime() would use under the hood). But it gets the two cases for
which it's designed correct:
- the result of gmtime() will have a zero offset, so no adjustment is
necessary
- the result of localtime() will be offset by the local zone offset,
and mktime() and strftime() are defined to assume this offset when
converting back (there's actually some magic here; some
implementations record this in the "struct tm", but we can't
portably access or manipulate it. But they somehow "know" whether a
"struct tm" is from gmtime() or localtime()).
This latter point means that "format-local:%s" actually works correctly
already, because in that case we rely on the system routines due to
6eced3ec5e (date: use localtime() for "-local" time formats,
2017-06-15). Our problem comes when trying to show times in the author's
zone, as the system routines provide no mechanism for converting in
non-local zones. So in those cases we have a "struct tm" that came from
gmtime(), but has been manipulated according to our offset.
The tests cover the broken round-trip by formatting "%s" for a time in a
non-system timezone. We use the made-up "+1234" here, which has two
advantages. One, we know it won't ever be the real system zone (and so
we're actually testing a case that would break). And two, since it has a
minute component, we're testing the full decoding of the +HHMM zone into
a number of seconds. Likewise, we test the "-1234" variant to make sure
there aren't any sign mistakes.
There's one final test, which covers "format-local:%s". As noted, this
already passes, but it's important to check that we didn't regress this
case. In particular, the caller in show_date() is relying on localtime()
to have done the zone adjustment, independent of any tz_offset we
compute ourselves. These should match up, since our local_tzoffset() is
likewise built around localtime(). But it would be easy for a caller to
forget to pass in a correct tz_offset to strbuf_addftime(). Fortunately
show_date() does this correctly (it has to because of the existing
handling of %z), and the test continues to pass. So this one is just
future-proofing against a change in our assumptions.

The filter system allows for alterations to file contents when they're
moved between the database and the worktree. We already made sure that
it is possible for smudge filters to produce contents that are larger
than `unsigned long` can represent (which matters on systems where
`unsigned long` is narrower than `size_t`, most notably 64-bit Windows).
Now we make sure that clean filters can _consume_ contents that are
larger than that.
Note that this commit only allows clean filters' _input_ to be larger
than can be represented by `unsigned long`.
This change makes only a very minute dent into the much larger project
to teach Git to use `size_t` instead of `unsigned long` wherever
appropriate.

There is mixed use of size_t and unsigned long to deal with sizes in the
codebase. Recall that Windows defines unsigned long as 32 bits even on
64-bit platforms, meaning that converting size_t to unsigned long narrows
the range. This mostly doesn't cause a problem since Git rarely deals
with files larger than 2^32 bytes.
But adjunct systems such as Git LFS, which use smudge/clean filters to
keep huge files out of the repository, may have huge file contents passed
through some of the functions in entry.c and convert.c. On Windows, this
results in a truncated file being written to the workdir. I traced this to
one specific use of unsigned long in write_entry (and a similar instance
in write_pc_item_to_fd for parallel checkout). That appeared to be for
the call to read_blob_entry, which expects a pointer to unsigned long.
By altering the signature of read_blob_entry to expect a size_t,
write_entry can be switched to use size_t internally (which all of its
callers and most of its callees already used). To avoid touching dozens of
additional files, read_blob_entry uses a local unsigned long to call a
chain of functions which aren't prepared to accept size_t.

The filter system allows for alterations to file contents when they're
added to the database or working tree. ("Smudge" when moving to the
working tree; "clean" when moving to the database.) This is used
natively to handle CRLF to LF conversions. It's also employed by Git-LFS
to replace large files from the working tree with small tracking files
in the repo and vice versa.
Git reads the entire smudged file into memory to convert it into a
"clean" form to be used in-core. While this is inefficient, there's a
more insidious problem on some platforms due to inconsistency between
using unsigned long and size_t for the same type of data (size of a file
in bytes). On most 64-bit platforms, unsigned long is 64 bits, and
size_t is typedef'd to unsigned long. On Windows, however, unsigned long
is only 32 bits (and therefore on 64-bit Windows, size_t is typedef'd to
unsigned long long in order to be 64 bits).
Practically speaking, this means 64-bit Windows users of Git-LFS can't
handle files larger than 2^32 bytes. Other 64-bit platforms don't suffer
this limitation.
This commit introduces a test exposing the issue; future commits make it
pass. The test simulates the way Git-LFS works by having a tiny file
checked into the repository and expanding it to a huge file on checkout.

This reverts the change from ed49584 (dir: fix pattern matching on dirs,
2021-09-24), which claimed to fix a directory-matching problem without a
test case. It turns out to _create_ a bug, but it is a bit subtle.
The bug would have been revealed by the first of two tests being added to
t0008-ignores.sh. The first uses a pattern "/git/" inside the a/.gitignores
file, which matches against 'a/git/foo' but not 'a/git-foo/bar'. This test
would fail before the revert.
The second test shows what happens if the test instead uses a pattern "git/"
and this test passes both before and after the revert.
The difference in these two cases are due to how
last_matching_pattern_from_list() checks patterns both if they have the
PATTERN_FLAG_MUSTBEDIR and PATTERN_FLAG_NODIR flags. In the case of "git/",
the PATTERN_FLAG_NODIR is also provided, making the change in behavior in
match_pathname() not affect the end result of
last_matching_pattern_from_list().
