The GitHub windows-meson-test jobs directly run "meson test" with the
--slice option. This means they skip all of the ci/lib.sh
infrastructure, and in particular:
1. They do not actually set any GIT_TEST_OPTS like --verbose-log or
-x.
2. They do not do the usual handle_failed_tests() magic to print test
failures or tar up failed directories.
As a result, you get almost no feedback at all when a test fails in this
job, making debugging rather tricky.
Let's try to make this behave more like the other CI jobs. Because we're
on Windows, we can't just use the normal run-build-and-tests.sh script.
Our build runs as a separate job (like the non-meson Windows job), and
then we parallelize the tests across several job slices. So we need
something like the run-test-slice.sh script that the "windows-test" job
uses.
In theory we could just swap out the "make" invocation there for
"meson". But it doesn't quite work, because "make" knows how to pull
GIT_TEST_OPTS out of GIT-BUILD-OPTIONS automatically. But for meson, we
have to extract them into the --test-args option ourselves. I tried
making the logic in run-test-slice.sh conditional, but there ended up
being hardly any common code at all (and there are some tricky ordering
constraints). So I added up with a new meson-specific test-slice runner.

In the same spirit as 9faf3963b6 (t: introduce compatibility options to
clar-based tests, 2024-12-13), we should ignore --no-chain-lint passed
to our clar tests, since it may appear in GIT_TEST_OPTS to be used with
other tests.
This is particularly important on Windows CI, where --no-chain-lint is
added to the test options by default, and the meson build will pass all
options to the unit tests. The only reason our meson Windows CI job does
not run into this currently is that it is not respecting GIT_TEST_OPTS
at all! So ignoring this option is a prerequisite to fixing that
situation.

ASan has an option to enable strict string checking, where any pointer
passed to a function that expects a NUL-terminated string will be
checked for that NUL termination. This can sometimes produce false
positives. E.g., it is not wrong to pass a buffer with { '1', '2', '\n' }
into strtoul(). Even though it is not NUL-terminated, it will stop at
the newline.
But in trying it out, it identified two problematic spots in our test
suite (which have now been adjusted):
1. The strtol() parsing in cache-tree.c was a real potential problem,
which would have been very hard to find otherwise (since it
required constructing a very specific broken index file).
2. The use of string functions in fsck_ident() were false positives,
because we knew that there was always a trailing newline which
would stop the functions from reading off the end of the buffer.
But the reasoning behind that is somewhat fragile, and silencing
those complaints made the code easier to reason about.
So even though this did not find any earth-shattering bugs, and even had
a few false positives, I'm sufficiently convinced that its complaints
are more helpful than hurtful. Let's turn it on by default (since the
test suite now runs cleanly with it) and see if it ever turns up any
other instances.

In fsck_ident(), we parse the timestamp with parse_timestamp(), which is
really an alias for strtoumax(). But since our buffer may not be
NUL-terminated, this can trigger a complaint from ASan's
strict_string_checks mode. This is a false positive, since we know that
the buffer contains a trailing newline (which we checked earlier in the
function), and that strtoumax() would stop there.
But it is worth working around ASan's complaint. One is because that
will let us turn on strict_string_checks by default, which has helped
catch other real problems. And two is that the safety of the current
code is very hard to reason about (it subtly depends on distant code
which could change).
One option here is to just parse the number left-to-right ourselves. But
we care about the size of a timestamp_t and detecting overflow, since
that's part of the point of these checks. And doing that correctly is
tricky. So we'll instead just pull the digits into a separate,
NUL-terminated buffer, and use that to call parse_timestamp().

After calling "parse_timestamp(p, &end, 10)", we complain if "p == end",
which would imply that we did not see any digits at all. But we know
this cannot be the case, since we would have bailed already if we did
not see any digits, courtesy of extra checks added by 8e4309038f (fsck:
do not assume NUL-termination of buffers, 2023-01-19). Since then,
checking "p == end" is redundant and we can drop it.
This will make our lives a little easier as we refactor further.

We may be operating on a buffer that is not NUL-terminated, but we use
strcspn() to parse it. This is OK in practice, as discussed in
8e4309038f (fsck: do not assume NUL-termination of buffers, 2023-01-19),
because we know there is at least a trailing newline in our buffer, and
we always pass "\n" to strcspn(). So we know it will stop before running
off the end of the buffer.
But this is a subtle point to hang our memory safety hat on. And it
confuses ASan's strict_string_checks mode, even though it is technically
a false positive (that mode complains that we have no NUL, which is
true, but it does not know that we have verified the presence of the
newline already).
Let's instead open-code the loop. As a bonus, this makes the logic more
obvious (to my mind, anyway). The current code skips forward with
strcspn until it hits "<", ">", or "\n". But then it must check which it
saw to decide if that was what we expected or not, duplicating some
logic between what's in the strcspn() and what's in the domain logic.
Instead, we can just check each character as we loop and act on it
immediately.

The fsck code purports to handle buffers that are not NUL-terminated,
but fsck_ident() uses some string functions. This works OK in practice,
as explained in 8e4309038f (fsck: do not assume NUL-termination of
buffers, 2023-01-19). Before calling fsck_ident() we'll have called
verify_headers(), which makes sure we have at least a trailing newline.
And none of our string-like functions will walk past that newline.
However, that makes this code at the top of fsck_ident() very confusing:
*ident = strchrnul(*ident, '\n');
if (**ident == '\n')
(*ident)++;
We should always see that newline, or our memory safety assumptions have
been violated! Further, using strchrnul() is weird, since the whole
point is that if the newline is not there, we don't necessarily have a
NUL at all, and might read off the end of the buffer.
So let's have callers pass in the boundary of our buffer, which lets us
safely find the newline with memchr(). And if it is not there, this is a
BUG(), because it means our caller did not validate the input with
verify_headers() as it was supposed to (and we are better off bailing
rather than having memory-safety problems).

A cache-tree extension entry in the index looks like this:
<name> NUL <entry_nr> SPACE <subtree_nr> NEWLINE <binary_oid>
where the "_nr" items are human-readable base-10 ASCII. We parse them
with strtol(), even though we do not have a NUL-terminated string (we'd
generally have an mmap() of the on-disk index file). For a well-formed
entry, this is not a problem; strtol() will stop when it sees the
newline. But there are two problems:
1. A corrupted entry could omit the newline, causing us to read
further. You'd mostly get stopped by seeing non-digits in the oid
field (and if it is likewise truncated, there will still be 20 or
more bytes of the index checksum). So it's possible, though
unlikely, to read off the end of the mmap'd buffer. Of course a
malicious index file can fake the oid and the index checksum to all
(ASCII) 0's.
This is further complicated by the fact that mmap'd buffers tend to
be zero-padded up to the page boundary. So to run off the end, the
index size also has to be a multiple of the page size. This is also
unlikely, though you can construct a malicious index file that
matches this.
The security implications aren't too interesting. The index file is
a local file anyway (so you can't attack somebody by cloning, but
only if you convince them to operate in a .git directory you made,
at which point attacking .git/config is much easier). And it's just
a read overflow via strtol(), which is unlikely to buy you much
beyond a crash.
2. ASan has a strict_string_checks option, which tells it to make sure
that options to string functions (like strtol) have some eventual
NUL, without regard to what the function would actually do (like
stopping at a newline here). This option sometimes has false
positives, but it can point to sketchy areas (like this one) where
the input we use doesn't exhibit a problem, but different input
_could_ cause us to misbehave.
Let's fix it by just parsing the values ourselves with a helper function
that is careful not to go past the end of the buffer. There are a few
behavior changes here that should not matter:
- We do not consider overflow, as strtol() would. But nor did the
original code. However, we don't trust the value we get from the
on-disk file, and if it says to read 2^30 entries, we would notice
that we do not have that many and bail before reading off the end of
the buffer.
- Our helper does not skip past extra leading whitespace as strtol()
would, but according to gitformat-index(5) there should not be any.
- The original quit parsing at a newline or a NUL byte, but now we
insist on a newline (which is what the documentation says, and what
Git has always produced).
Since we are providing our own helper function, we can tweak the
interface a bit to make our lives easier. The original code does not use
strtol's "end" pointer to find the end of the parsed data, but rather
uses a separate loop to advance our "buf" pointer to the trailing
newline. We can instead provide a helper that advances "buf" as it
parses, letting us read strictly left-to-right through the buffer.
I didn't add a new test here. It's surprisingly difficult to construct
an index of exactly the right size due to the way we pad entries. But it
is easy to trigger the problem in existing tests when using ASan's
strict string checking, coupled with a recent change to use NO_MMAP with
ASan builds. So:
make SANITIZE=address
cd t
ASAN_OPTIONS=strict_string_checks=1 ./t0090-cache-tree.sh
triggers it reliably. Technically it is not deterministic because there
is ~8% chance (it's 1-(255/256)^20, or ^32 for sha256) that the trailing
checksum hash has a NUL byte in it. But we compute enough cache-trees in
the course of that script that we are very likely to hit the problem in
one of them.
We can look at making strict_string_checks the default for ASan builds,
but there are some other cases we'd want to fix first.

Git often uses mmap() to access on-disk files. This leaves a blind spot
in our SANITIZE=address builds, since ASan does not seem to handle mmap
at all. Nor does the OS notice most out-of-bounds access, since it tends
to round up to the nearest page size (so depending on how big the map
is, you might have to overrun it by up to 4095 bytes to trigger a
segfault).
The previous commit demonstrates a memory bug that we missed. We could
have made a new test where the out-of-bounds access was much larger, or
where the mapped file ended closer to a page boundary. But the point of
running the test suite with sanitizers is to catch these problems
without having to construct specific tests.
Let's enable NO_MMAP for our ASan builds by default, which should give
us better coverage. This does increase the memory usage of Git, since
we're copying from the filesystem into heap. But the repositories in the
test suite tend to be small, so the overhead isn't really noticeable
(and ASan already has quite a performance penalty).
There are a few other known bugs that this patch will help flush out.
However, they aren't directly triggered in the test suite (yet). So
it's safe to turn this on now without breaking the test suite, which
will help us add new tests to demonstrate those other bugs as we fix
them.

If a bitmap has a name-hash cache, it is an array of 32-bit integers,
one per entry in the bitmap, which we've mmap'd from the .bitmap file.
We access it directly like this:
if (bitmap_git->hashes)
hash = get_be32(bitmap_git->hashes + index_pos);
That works for both regular pack bitmaps and for non-incremental midx
bitmaps. There is one bitmap_index with one "hashes" array, and
index_pos is within its bounds (we do the bounds-checking when we load
the bitmap).
But for an incremental midx bitmap, we have a linked list of
bitmap_index structs, and each one has only its own small slice of the
name-hash array. If index_pos refers to an object that is not in the
first bitmap_git of the chain, then we'll access memory outside of the
bounds of its "hashes" array, and often outside of the mmap.
Instead, we should walk through the list until we find the bitmap_index
which serves our index_pos, and use its hash (after adjusting index_pos
to make it relative to the slice we found). This is exactly what we do
elsewhere for incremental midx lookups (like the pack_pos_to_midx() call
a few lines above). But we can't use existing helpers like
midx_for_object() here, because we're walking through the chain of
bitmap_index structs (each of which refers to a midx), not the chain of
incremental multi_pack_index structs themselves.
The problem is triggered in the test suite, but we don't get a segfault
because the out-of-bounds index is too small. The OS typically rounds
our mmap up to the nearest page size, so we just end up accessing some
extra zero'd memory. Nor do we catch it with ASan, since it doesn't seem
to instrument mmaps at all. But if we build with NO_MMAP, then our maps
are replaced with heap allocations, which ASan does check. And so:
make NO_MMAP=1 SANITIZE=address
cd t
./t5334-incremental-multi-pack-index.sh
does show the problem (and this patch makes it go away).

Our mmap compat code emulates mapping by using malloc/free. Our
git_munmap() must take a "length" parameter to match the interface of
munmap(), but we don't use it (it is up to the allocator to know how big
the block is in free()).
Let's mark it as UNUSED to avoid complaints from -Wunused-parameter.
Otherwise you cannot build with "make DEVELOPER=1 NO_MMAP=1".

At GitHub, we had a repository that was triggering
git: merge-ort.c:3032: process_renames: Assertion `newinfo && !newinfo->merged.clean` failed.
during git replay.
This sounds similar to the somewhat recent f6ecb603ff8a (merge-ort: fix
directory rename on top of source of other rename/delete, 2025-08-06),
but the cause is different. Unlike that case, there are no
rename-to-self situations arising in this case, and new to this case it
can only be triggered during a replay operation on the 2nd or later
commit being replayed, never on the first merge in the sequence.
To trigger, the repository needs:
* an upstream which:
* renames a file to a different directory, e.g.
old/file -> new/file
* leaves other files remaining in the original directory (so that
e.g. "old/" still exists upstream even though file has been
removed from it and placed elsewhere)
* a topic branch being rebased where:
* a commit in the sequence:
* modifies old/file
* a subsequent commit in the sequence being replayed:
* does NOT touch *anything* under new/
* does NOT touch old/file
* DOES modify other paths under old/
* does NOT have any relevant renames that we need to detect
_anywhere_ elsewhere in the tree (meaning this interacts
interestingly with both directory renames and cached renames)
In such a case, the assertion will trigger. The fix turns out to be
surprisingly simple. I have a very vague recollection that I actually
considered whether to add such an if-check years ago when I added the
very similar one for oldinfo in 1b6b902d95a5 (merge-ort:
process_renames() now needs more defensiveness, 2021-01-19), but I think
I couldn't figure out a possible way to trigger it and was worried at
the time that if I didn't know how to trigger it then I wasn't so sure
that simply skipping it was correct. Waiting did give me a chance to
put more thorough tests and checks into place for the rename-to-self
cases a few months back, which I might not have found as easily
otherwise. Anyway, put the check in place now and add a test that
demonstrates the fix.
Note that this bug, as demonstrated by the conditions listed above,
runs at the intersection of relevant renames, trivial directory
resolutions, and cached renames. All three of those optimizations are
ones that unfortunately make the code (and testcases!) a bit more
complex, and threading all three makes it a bit more so. However, the
testcase isn't crazy enough that I'd expect no one to ever hit it in
practice, and was confused why we didn't see it before. After some
digging, I discovered that merge.directoryRenames=false is a workaround
to this bug, and GitHub used that setting until recently (it was a
"temporary" match-what-libgit2-does piece of code that lasted years
longer than intended). Since the conditions I gave above for triggering
this bug rule out the possibility of there being directory renames, one
might assume that it shouldn't matter whether you try to detect such
renames if there aren't any. However, due to commit a16e8efe5c2b
(merge-ort: fix merge.directoryRenames=false, 2025-03-13), the heavy
hammer used there means that merge.directoryRenames=false ALSO turns off
rename caching, which is critical to triggering the bug. This becomes
a bit more than an aside since...
Re-reading that old commit, a16e8efe5c2b (merge-ort: fix
merge.directoryRenames=false, 2025-03-13), it appears that the solution
to this latest bug might have been at least a partial alternative
solution to that old commit. And it may have been an improved
alternative (or at least help implement one), since it may be able to
avoid the heavy-handed disabling of rename cache. That might be an
interesting future thing to investigate, but is not critical for the
current fix. However, since I spent time digging it all up, at least
leave a small comment tweak breadcrumb to help some future reader
(myself or others) who wants to dig further to connect the dots a little
quicker.

As a preparation for this move, it is worth making sure that the diff

In a following commit, we are going to check commit signatures, but we
won't have a commit yet, only a commit buffer, and we are going to
discard this commit buffer if the signature is invalid. So it would be
wasteful to create a commit that we might discard, just to be able to
check a commit signature.
It would be simpler instead to be able to check commit signatures
using only a commit buffer instead of a commit.
To be able to do that, let's extract some code from the
check_commit_signature() function into a new verify_commit_buffer()
function, and then let's make check_commit_signature() call
verify_commit_buffer().
Note that this doesn't fundamentally change how
check_commit_signature() works. It used to call parse_signed_commit()
which calls repo_get_commit_buffer(), parse_buffer_signed_by_header()
and repo_unuse_commit_buffer(). Now these 3 functions are called
directly by verify_commit_buffer().

UTF-8 characters (e.g., non-ASCII glyphs). E.g.:
| 仓库结构 | 值 |
| -------------- | ---- |
| * 引用 | |
| * 计数 | 67 |
The previous implementation used simple width formatting with printf()
which didn't properly handle multi-byte UTF-8 characters, causing
misaligned table columns when displaying repository structure
information.
This change modifies the stats_table_print_structure function to use
strbuf_utf8_align() instead of basic printf width specifiers. This
ensures proper column alignment regardless of the character encoding of
the content being displayed.
Also add test cases for strbuf_utf8_align(), a function newly introduced
in "builtin/repo.c".

The file "builtin/repo.c" uses utf8_strwidth() to calculate the display
width of UTF-8 characters in a table, but the resulting output is still
misaligned. Add test cases for both utf8_strwidth and utf8_strnwidth to
verify that they correctly compute the display width for UTF-8
characters.
Also updated the build configuration in Makefile and meson.build to
include the new test suite in the build process.

The previous step replaced deprecated macos-13 image with macos-14
image on GitHub Actions CI. While x86-64 binaries can work there,
because macos-14 images are arm64 based (we could replace it with
macos-14-large that is x86-64), it makes more sense to use arm64
binary there. Without this change, we have been getting unusually
higher rate of failures from random macOS CI jobs railing to run
t98xx series of tests.

In add_to_cache(), we treat any directories as submodules, and complain
if we can't resolve their HEAD. This call to resolve_gitlink_ref() was
added by f937bc2f86 (add: error appropriately on repository with no
commits, 2019-04-09), with the goal of improving the error message for
empty repositories.
But we already resolve the submodule HEAD in index_path(), which is
where we find the actual oid we're going to use. Resolving it again here
introduces some downsides:
1. It's more work, since we have to open up the submodule repository's
files twice.
2. There are call paths that get to index_path() without going through
add_to_cache(). For instance, we'd want a similar informative
message if "git diff empty" finds that it can't resolve the
submodule's HEAD. (In theory we can also get there through
update-index, but AFAICT it refuses to consider directories as
submodules at all, and just complains about them).
3. The resolution in index_path() catches more errors that we don't
handle here. In particular, it will validate that the object format
for the submodule matches that of the superproject. This isn't a
bug, since our call in add_to_cache() throws away the oid it gets
without looking at it. But it certainly caused confusion for me
when looking at where the object-format check should go.
So instead of resolving the submodule HEAD in add_to_cache(), let's just
teach the call in index_path() to actually produce an error message
(which it already does for other cases). That's probably what f937bc2f86
should have done in the first place, and it gives us a single point of
resolution when adding a submodule to the index.
The resulting output is slightly more verbose, as we propagate the error
up the call stack, but I think that's OK (and again, matches many other
errors we get when indexing fails).
I've left the text of the error message as-is, though it is perhaps
overly specific. There are many reasons that resolving the submodule
HEAD might fail, though outside of corruption or system errors it is
probably most likely that the submodule HEAD is simply on an unborn
branch.

The design of the hash algorithm transition plan is that objects stored
must be entirely in one algorithm since we lack any way to indicate a
mix of algorithms. This also includes submodules, but we have
traditionally not enforced this, which leads to various problems when
trying to clone or check out the the submodule from the remote.
Since this cannot work in the general case, restrict adding a submodule
of a different algorithm to the index. Add tests for git add and git
submodule add that these are rejected.
Note that we cannot check this in git fsck because the malformed
submodule is stored in the tree as an object ID which is either
truncated (when a SHA-256 submodule is added to a SHA-1 repository) or
padded with zeros (when a SHA-1 submodule is added to a SHA-256
repository). We cannot detect even the latter case because someone
could have an actual submodule that actually ends in 24 zeros, which
would be a false positive.

`--branch` and `--long` refer to git-status(1) options but they don’t tell us
what `short-format` and `long-format` are, respectively. And `--null`
mentions “status” but does not link to the command.
Refer to git-config(1) on `--branch` like `--short` does.
`long-format` is the git-status(1) output. So we can just say that
directly.
Replace “status” with a `linkgit` on `--null`.

git-credential-osxkeychain skips storing a credential if its "get"
action sets "state[]=osxkeychain:seen=1". This behavior was introduced
in e1ab45b2 (osxkeychain: state to skip unnecessary store operations,
2024-05-15), which appeared in v2.46.
However, this state[] persists even if a credential returned by
"git-credential-osxkeychain get" is invalid and a subsequent helper's
"get" operation returns a valid credential. Another subsequent helper
(such as [1]) may expect git-credential-osxkeychain to store the valid
credential, but the "store" operation is incorrectly skipped because it
only checks "state[]=osxkeychain:seen=1".
To solve this issue, "state[]=osxkeychain:seen" needs to contain enough
information to identify whether the current "store" input matches the
output from the previous "get" operation (and not a credential from
another helper).
Set "state[]=osxkeychain:seen" to a value encoding the credential output
by "get", and compare it with a value encoding the credential input by
"store".
