I noticed recently that the leak-checking jobs still take a lot of time,
and upon analysis, the git-svn tests contribute significantly to this.
Analyzing a recent CI run, I saw that the Git test suite contains
1,017 tests, running for approximately 5¼ hours total. Of these, 65
git-svn-related tests (~6% of test count) took 42.24 minutes combined,
accounting for ~13.% of the total runtime. This implies that the git-svn
tests are roughly twice as expernsive compared to the other tests.
However, testing git-svn in the leak-checking jobs provides minimal
value: git-svn is implemented as a Perl script, and leak checking only
handles C code. While git-svn does call into Git's built-in commands
that are implemented in C, these are standard Git operations that are
already thoroughly exercised elsewhere in the test suite. Therefore,
running the git-svn tests in the leak-checking jobs only adds to the
overall run time with little value in return.
Given that the leak-checking jobs are particularly time-intensive and
these 42+ minutes of SVN tests per job provide no additional leak
detection value, skip them in the *-leaks jobs to reduce CI runtime.

t0610-reftable-basics: mitigate a flaky test on cygwin
Test #29 ('ref transaction: corrupted tables cause failure') started to
fail intermittently for me (from v2.52.0-rc0) when running the testsuite
with '-j8'. (Also, having moved to a new laptop and windows 11, rather
than windows 10). If the test is run by hand, or without any parallelism,
then it passes without issue.
When the test fails (e.g. 1 out of 32 parallel runs) the cause is due to
a permission error while corrupting a table file:
./test-lib.sh: line 1010: .git/reftable/0x000000000001-0x000000000002-d89bb8ee.ref: Permission denied
This corruption is done in a shell loop, directly after a 'test_commit',
which uses an ': >"$f"' expression to truncate the file. Adding a sleep
of one second after the 'test_commit' and before the shell loop fixes
the test (it is not clear why). Replacing the redirection shell expression
with a 'test-tool truncate "$f" 0' invocation also provides a fix, which
could simply be another way to change the timing sufficiently to win the
race.
During a debug session, I tried looking at the strace output for the
shell redirection:
$ rm /tmp/hello; echo hello >/tmp/hello; ls -l /tmp/hello
-rw-r--r-- 1 ramsay None 6 Nov 10 17:25 /tmp/hello
$
When comparing the output, the differences seemed to be what you would
expect and, if anything, the shell redirect probably would have taken
longer than the test-tool solution (many fcntl() calls to dup the stdout
to the <fd>). The call to the win32 api NtCreateFile() was identical,
apart from the first (FileHandle) parameter, of course.
In order to fix this flaky test on cygwin, despite not knowing why it
works, replace the shell redirection with the above 'test-tool truncate'
invocation.

builtin/repack: handle promisor packs with geometric repacking
When performing a fetch with an object filter, we mark the resulting
packfile as a promisor pack. An object part of such a pack may miss any
of its referenced objects, and Git knows to handle this case by fetching
any such missing objects from the promisor remote.
The "promisor" property needs to be retained going forward. So every
time we pack a promisor object, the resulting pack must be marked as a
promisor pack. git-repack(1) does this already: when a repository has a
promisor remote, it knows to pass "--exclude-promisor-objects" to the
git-pack-objects(1) child process. Promisor packs are written separately
when doing an all-into-one repack via `repack_promisor_objects()`.
But we don't support promisor objects when doing a geometric repack yet.
Promisor packs do not get any special treatment there, as we simply
merge promisor and non-promisor packs. The resulting pack is not even
marked as a promisor pack, which essentially corrupts the repository.
This corruption couldn't happen in the real world though: we pass both
"--exclude-promisor-objects" and "--stdin-packs" to git-pack-objects(1)
if a repository has a promisor remote, but as those options are mutually
exclusive we always end up dying. And while we made those flags
compatible with one another in a preceding commit, we still end up dying
in case git-pack-objects(1) is asked to repack a promisor pack.
There's multiple ways to fix this:
- We can exclude promisor packs from the geometric progression
altogether. This would have the consequence that we never repack
promisor packs at all. But in a partial clone it is quite likely
that the user generates a bunch of promisor packs over time, as
every backfill fetch would create another one. So this doesn't
really feel like a sensible option.
- We can adapt git-pack-objects(1) to support repacking promisor packs
and include them in the normal geometric progression. But this would
mean that the set of promisor objects expands over time as the packs
are merged with normal packs.
- We can use a separate geometric progression to repack promisor
packs.
The first two options both have significant downsides, so they aren't
really feasible. But the third option fixes both of these downsides: we
make sure that promisor packs get merged, and at the same time we never
expand the set of promisor objects beyond the set of objects that are
already marked as promisor objects.
Implement this strategy so that geometric repacking works in partial
clones.

builtin/pack-objects: exclude promisor objects with "--stdin-packs"
It is currently not possible to combine "--exclude-promisor-objects"
with "--stdin-packs" because both flags want to set up a revision walk
to enumerate the objects to pack. In a subsequent commit though we want
to extend geometric repacks to support promisor objects, and for that we
need to handle the combination of both flags.
There are two cases we have to think about here:
- "--stdin-packs" asks us to pack exactly the objects part of the
specified packfiles. It is somewhat questionable what to do in the
case where the user asks us to exclude promisor objects, but at the
same time explicitly passes a promisor pack to us. For now, we
simply abort the request as it is self-contradicting. As we have
also been dying before this commit there is no regression here.
- "--stdin-packs=follow" does the same as the first flag, but it also
asks us to include all objects transitively reachable from any
object in the packs we are about to repack. This is done by doing
the revision walk mentioned further up. Luckily, fixing this case is
trivial: we only need to modify the revision walk to also set the
`exclude_promisor_objects` field.
Note that we do not support the "--exclude-promisor-objects-best-effort"
flag for now as we don't need it to support geometric repacking with
promisor objects.

midx-write.c: assume checksum-invalid MIDXs require an update
In 6ce9d558ced (midx-write: skip rewriting MIDX with `--stdin-packs`
unless needed, 2025-12-10), the MIDX machinery learned how to optimize
out unnecessary writes with "--stdin-packs".
In order to do this, it compares the contents of the in-progress write
against a MIDX loaded directly from the object store. We load a separate
MIDX (as opposed to checking our update relative to "ctx.m") because the
MIDX code does not reuse an existing MIDX with --stdin-packs, and always
leaves "ctx.m" as NULL. See commit 0c5a62f14bc (midx-write.c: do not
read existing MIDX with `packs_to_include`, 2024-06-11) for details on
why.
If "ctx.m" is non-NULL, however, it is guaranteed to be checksum-valid,
since we only assign "ctx.m" when "midx_checksum_valid()" returns true.
Since the same guard does not exist for the MIDX we pass to
"midx_needs_update()", we may ignore on-disk corruption when determining
whether or not we can optimize out the write.
Add a similar guard within "midx_needs_update()" to prevent such an
issue.
A more robust fix would involve revising 0c5a62f14bc and teaching the
MIDX generation code how to reuse an existing MIDX even when invoked
with "--stdin-packs", such that we could avoid side-loading the MIDX
directly from the object store in order to call "midx_needs_update()".
For now, pursue the minimal fix.

It is enabled when a MacOS version is used that has a buggy
iconv library and there is no external library provided
(and linked against) from neither MacPorts nor Homebrew nor Fink.
For Homebrew, MacPorts and Fink we check if libiconv exist.
Introduce 2 new macros: HAS_GOOD_LIBICONV and NEEDS_GOOD_LIBICONV.
For Homebrew HAS_GOOD_LIBICONV is set when the libiconv directory
exist.
MacPorts can be installed with or without libiconv, so check if
libiconv.dylib exists (which is a softlink)
Fink compiles and installs libiconv by default.
Note that a fresh installation of Fink now defaults to /opt/sw.
Older versions used /sw as default, so leave the check and setting
of BASIC_CFLAGS and BASIC_LDFLAGS as is.
For the new default check for the existance of /opt/sw as well.
Add a check for /opt/sw/lib/libiconv.dylib which sets HAS_GOOD_LIBICONV

utf8.c: prepare workaround for iconv under macOS 14/15
MacOS14 (Sonoma) has started to ship an iconv library with bugs.
The same bugs exists even in MacOS 15 (Sequoia)
A bug report running the Git test suite says:
three tests of t3900 fail on macOS 26.1 for me:
not ok 17 - ISO-2022-JP should be shown in UTF-8 now
not ok 25 - ISO-2022-JP should be shown in UTF-8 now
not ok 38 - commit --fixup into ISO-2022-JP from UTF-8
Here's the verbose output of the first one:
=================
expecting success of 3900.17 'ISO-2022-JP should be shown in UTF-8 now':
compare_with ISO-2022-JP "$TEST_DIRECTORY"/t3900/2-UTF-8.txt
しているのが、いるので。
-濱浜ほれぷりぽれまびぐりろへ。
+濱浜ほれぷりぽれまび$0$j$m$X!#
not ok 17 - ISO-2022-JP should be shown in UTF-8 now
1..17
=================
compare_with runs git show to display a commit message, which in this
case here was encoded using ISO-2022-JP and is supposed to be reencoded
to UTF-8, but git show only does that half-way -- the "$0$j$m$X!#" part
is from the original ISO-2022-JP representation.
That botched conversion is done by utf8.c::reencode_string_iconv(). It
calls iconv(3) to do the actual work, initially with an output buffer of
the same size as the input. If the output needs more space the function
enlarges the buffer and calls iconv(3) again.
iconv(3) won't tell us how much space it needs, but it will report what
part it already managed to convert, so we can increase the buffer and
continue from there. ISO-2022-JP has escape codes for switching between
character sets, so it's a stateful encoding. I guess the iconv(3) on my
machine forgets the state at the end of part one and then messes up part
two.

Working around the buggy iconv shipped with the OS can be done in
two ways:
a) Link Git against a different version of iconv
b) Improve the handling when iconv needs a larger output buffer
a) is already done by default when either Fink [1] or MacPorts [2]
or Homebrew [3] is installed.
b) is implemented here, in case that no fixed iconv is available:
When the output buffer is too short, increase it (as before)
and start from scratch (this is new).
This workound needs to be enabled with
'#define ICONV_RESTART_RESET'
and a makefile knob will be added in the next commit
The function `fsck_head_link()` was historically used to perform a
couple of consistency checks for refs. (Almost) all of these checks have
now been moved into the refs subsystem. There's only a single check
remaining that verifies whether `refs_resolve_ref_unsafe()` returns a
`NULL` pointer. This may happen in a couple of cases:
- When `refs_is_safe()` declares the ref to be unsafe. We already have
checks for this as we verify refnames with `check_refname_format()`.
- When the ref doesn't exist. A repository without "HEAD" is
completely broken though, and we would notice this error ahead of
time already.
- In case the caller passes `RESOLVE_REF_READING` and the ref is a
symref that doesn't resolve. We don't pass this flag though.
As such, this check doesn't cover anything anymore that isn't already
covered by `refs_fsck()`. Drop it, which also allows us to inline the
call to `refs_resolve_ref_unsafe()`.

builtin/fsck: move generic object ID checks into `refs_fsck()`
While most of the logic that verifies the consistency of refs is
driven by `refs_fsck()`, we still have a small handful of checks in
`fsck_head_link()`. These checks don't use the git-fsck(1) reporting
infrastructure, and as such it's impossible to for example disable
some of those checks.
One such check detects refs that point to the all-zeroes object ID.
Extract this check into the generic `refs_fsck_ref()` function that is
used by both the "files" and "reftable" backends.
Note that this will cause us to not return an error code from
`fsck_head_link()` anymore in case this error was detected. This is fine
though: the only caller of this function does not check the error code
anyway. To demonstrate this, adapt the function to drop its return value
altogether. The function will be removed in a subsequent commit anyway.

In a preceding commit we have extracted generic checks for both direct
and symbolic refs that apply for all backends. Wire up those checks for
the "reftable" backend.
Note that this is done by iterating through all refs manually with the
low-level reftable ref iterator. We explicitly don't want to use the
higher-level iterator that is exposed to users of the reftable backend
as that iterator may swallow for example broken refs.
