build: tolerate use of _Generic from glibc 2.43 with Clang
When building with `make DEVELOPER=1` we explicitly pass "-std=gnu99" to
the compiler so that we don't start leaning on features exposed by more
recent versions of the C standard. Unfortunately though, glibc 2.43
started to use type-generic expressions. This works alright with GCC,
but when compiling with Clang this leads to errors:
$ make DEVELOPER=1 CC=clang
CC daemon.o
In file included from daemon.c:3:
./git-compat-util.h:344:11: error: '_Generic' is a C11 extension [-Werror,-Wc11-extensions]
344 | return !!strchr(path, '/');

/usr/include/string.h:265:3: note: expanded from macro 'strchr'

838 | _Generic (0 ? (PTR) : (void *) 1, \
| ^
In theory, the `__glibc_const_generic` macro does have feature gating:
#if !defined __cplusplus \
&& (__GNUC_PREREQ (4, 9) \
|| __glibc_has_extension (c_generic_selections) \
|| (!defined __GNUC__ && defined __STDC_VERSION__ \
&& __STDC_VERSION__ >= 201112L))
# define __HAVE_GENERIC_SELECTION 1
#else
# define __HAVE_GENERIC_SELECTION 0
#endif
But this feature gating isn't effective because `_has_extension()` will
always evaluate to true as C generics _are_ available as a language
extension to GNU C99 when using Clang. This would have been different if
`_has_feature()` was used instead, in which case it would have properly
evaluated to `false`.
GCC has a workaround to squelch this warning from standard system
headers, but because clang fails due to [-Werror,-Wc11-extensions],
as it lacks the corresponding workaround.
For both meson and Makefile, pass -Wno-c11-extensions when we are
building with clang.

As is done for all the other maintenance tasks, let's release the ODB
also before starting the geometric repacking. That way, the `.idx` files
won't be `mmap()`ed when they are to be deleted (which does not work on
Windows because you cannot delete files on that platform as long as they
are kept open by a process).
This regression was introduced by 9bc151850c (builtin/maintenance:
introduce "geometric-repack" task, 2025-10-24), but was only noticed
once geometric repacking was made the default in 452b12c2e0 (builtin/
maintenance: use "geometric" strategy by default, 2026-02-24).
The fix recapitulates my work from df76ee7b77f0 (run-command: offer to
close the object store before running, 2021-09-09) & friends.
To guard against future regressions of this kind, add a check to
`run_and_verify_geometric_pack()` in `t7900` that detects orphaned
`.idx` files left behind after repacking. Contrary to interactive
calls, the `git maintenance` call in that test case would _not_ block on
Windows, asking whether to retry deleting that file, which is the reason
why this bug was not caught earlier.
Furthermore, since the default behavior of `DeleteFileW()` was changed
at some point between Windows 10 Build 17134.1304 and Build 18363.657
to use POSIX semantics (see https://stackoverflow.com/a/60512798),
the added orphaned-`.idx` check would be insufficient to catch this
regression on modern Windows without emulating legacy delete semantics
via `GIT_TEST_LEGACY_DELETE=1`.
This fixes https://github.com/git-for-windows/git/issues/6210.

At some point between Windows 10 Build 17134.1304 and Build 18363.657,
the default behavior of `DeleteFileW()` was changed to use POSIX
semantics (https://stackoverflow.com/a/60512798). Under those semantics,
a file can be deleted even when another process holds an active
`MapViewOfFile` view on it: the directory entry is removed immediately,
but the underlying data persists until the last handle is closed.
On older Windows versions (and Windows 10 builds before that change),
`DeleteFileW()` uses legacy semantics where deletion fails outright if
any process holds a file mapping.
To allow testing code paths that depend on the legacy behavior, introduce
a `GIT_TEST_LEGACY_DELETE` environment variable. When set, `mingw_unlink()`
uses `SetFileInformationByHandle()` with `FileDispositionInfo` (the
non-POSIX variant) instead of `DeleteFileW()`, forcing legacy delete
semantics regardless of the Windows version.

The l10n workflow uses `mshick/add-pr-comment` to post git-po-helper
reports as comments on translation pull requests. It was still pinned
to v2, which runs on Node.js 20. GitHub is phasing out the Node.js 20
runtime on Actions runners, so staying on v2 will eventually cause the
"Create comment in pull request for report" step to fail.
The sole breaking change in v3 is the switch from Node.js 20 to
Node.js 24 (https://github.com/mshick/add-pr-comment/releases/tag/v3.0.0).
The action's inputs and outputs are unchanged, so the upgrade is a
drop-in replacement. Subsequent v3.x releases added new opt-in
features (message truncation, retry with exponential backoff, file
attachments, commit comment support, "delete on status") but none of
them affect existing callers that do not opt in.

The v1 of `git-for-windows/setup-git-for-windows-sdk` runs on
Node.js 20, which GitHub is phasing out of the Actions runners.
v2 moves the action to Node.js 24 so that the CI jobs relying on
a Git for Windows SDK keep working once Node.js 20 is removed.
The risk is very low: v2 contains no functional changes to the
SDK setup itself, only the runtime upgrade. The action still
provisions the same minimal SDK and exposes the same outputs.
The sole precondition is a recent Actions Runner (>= 2.327.1),
which the github.com-hosted runners already satisfy.

Every workflow currently pins `actions/checkout` to v5, which was
introduced primarily to move to the Node.js 24 runtime. v6 is the
next release and worth picking up so we stay on a maintained version
of the action.
The one behaviorally interesting change in v6:
`persist-credentials` now stores the helper credentials under
`$RUNNER_TEMP` instead of writing them directly into the local
`.git/config`. Two implications follow:
1. In the normal case this is an unambiguous improvement -- the
token no longer lands in `.git/config`, reducing the risk of
inadvertently leaking it through workspace archiving
(`upload-artifact` snapshots, cache entries, core dumps, ...).
2. Docker container actions require an Actions Runner of at least
v2.329.0 to find the credentials in their new location. The
github.com-hosted runners our CI uses are already past that
version, so this does not affect us. Downstream users running
self-hosted runners may need to update them before adopting
this version of the action.
Risk analysis: our checkout steps either check out the default
repository (no special credential requirements) or, in the `vs-build`
job, explicitly set `repository: microsoft/vcpkg` and
`path: compat/vcbuild/vcpkg`. Neither case relies on the precise
location of the persisted credentials -- subsequent steps interact
with the API via the runner-provided `GITHUB_TOKEN` directly -- so
the v6 credential-storage change is transparent to our workflows.
The diff is purely the `@vN` identifier; there are no input or
output changes.

The only use we have of `actions/github-script` is the "skip if the
commit or tree was already tested" step in `main.yml`, which checks
whether an identical tree-SHA was already built successfully. It
currently pins v8; v9 is the latest release.
What v9 changes:
- The `ACTIONS_ORCHESTRATION_ID` environment variable is now
appended to the HTTP user-agent string. This is transparent to
our script.
- A new injected `getOctokit` factory lets scripts create
additional authenticated clients in the same step without
importing `@actions/github`. We do not use it.
- Two breaking changes affect scripts that either call
`require('@actions/github')` (fails at runtime, because
`@actions/github` v9 is now ESM-only) or that shadow the
implicit `getOctokit` parameter via `const`/`let` (syntax
error). Our script does neither -- it only uses the pre-supplied
`github` REST client and `core` helpers -- so the upgrade is
safe.
Risk analysis: the step is advisory. It sets `enabled=' but skip'`
as an optimization to avoid re-running CI on a tree that was already
tested successfully. Even if the v9 upgrade broke the script, the
surrounding `try { ... } catch (e) { core.warning(e); }` block would
degrade it to a warning and CI would still run normally. In practice
the script continues to work identically on v9.

`actions/upload-artifact` and `actions/download-artifact` are tightly
coupled: the upload action writes artifact archives in a format that
the download action then reads. Because of this coupling, the two
actions should always be bumped together so that the artifact format
contract between them is satisfied.
All of our `actions/upload-artifact` uses are still on v5, with one
stray v4 occurrence. Keeping them on these versions would leave the
artifact-upload steps running on Node.js 20, which GitHub is phasing
out, and would eventually cause all upload steps to fail.
Going from v5 directly to v7 folds in two release bumps:
- v6 switches the action's default runtime from Node.js 20 to
Node.js 24 (v5 had preliminary Node 24 support but still defaulted
to Node 20). This is the main motivation for bumping now: it gets
us off the deprecated runtime.
- v7 adds two opt-in features: direct (unzipped) single-file uploads
via a new `archive: false` parameter, and an internal conversion of
the action to ESM to match the updated `@actions/*` packages.
Risk analysis: we never pass `archive`, so the zip-as-usual behavior
is unchanged. We also do not `require('@actions/*')` from any calling
workflow, so the ESM migration cannot affect us. The upload steps we
care about -- tracked files/build artifacts and failing-test
directories -- keep the same inputs (`name`, `path`) and outputs, so
the diff is purely the `@vN` identifier. The main precondition is a
recent Actions Runner (>= 2.327.1), which the github.com-hosted
runners used by our CI already satisfy.
While at it, align the one remaining `@v4` occurrence with the rest
so that every `upload-artifact` step uses the same version.

We use `actions/download-artifact` to pass build artifacts between
the "windows-build" / "vs-build" / "windows-meson-build" jobs and
their corresponding test jobs. All callers are currently on v6;
bumping to v8 keeps this action in lockstep with the `upload-artifact`
bump above.
What v7 and v8 change:
- v7 switches the default runtime from Node.js 20 to Node.js 24 (v6
had preliminary Node 24 support but still defaulted to Node 20).
This is the main motivation: it gets us off the deprecated runtime.
- v8 makes three further changes:
* The package is converted to ESM (invisible to workflow authors).
* The action now checks the `Content-Type` header before
attempting to unzip a download, so that directly-uploaded
(unzipped) artifacts from `upload-artifact` v7 are downloaded
correctly.
* The `digest-mismatch` behaviour is changed from warn-and-
continue to a hard failure by default.
Risk analysis: defaulting hash-mismatch to a hard failure is
strictly safer than the previous warn-and-continue behaviour -- a
mismatch points to real corruption or tampering and should stop the
run. We download archives that the same workflow just uploaded, on
the same runner fleet, so false positives are not expected. Our
usage is limited to the `name` and `path` inputs, which are
unchanged between v6 and v8, so the diff is purely the `@vN`
identifier.

only substantive change is moving the action's runtime to Node.js 24,
so that our Visual Studio build jobs keep working once Node.js 20 is

The risk of this bump is very low: v3 contains no functional changes

resolution. The only precondition is a recent-enough Actions Runner,

The SOCKS proxy test introduced in 0ca365c2ed (http: do not ignore
proxy path, 2024-08-02) creates a Unix domain socket in
`$TRASH_DIRECTORY`. When the trash directory path is long (e.g.
when running from a deeply nested worktree), the socket path can
exceed the 108-character limit for `struct sockaddr_un.sun_path` on
Linux, causing the test to fail with "Path length ... is longer
than maximum supported length (108)".
We cannot work around this using the chdir trick our own socket code
employs, because both sides of the connection are outside our control:
the socket is created by socks4-proxy.pl via Perl's IO::Socket::UNIX,
and the client side is libcurl.
Use `mktemp -d` to create a unique temporary directory with a short
path, and place the socket inside it. This avoids collisions between
concurrent test runs (e.g. `--stress`) and tmpdir-race vulnerabilities
that a static `/tmp` path would be susceptible to.

This reverts commit dd3693eb08.
The goal of that commit was to avoid zombie child processes hanging
around when the parent git process is killed. But it doesn't quite work
when the child command is run by the shell:
1. If there is a shell, then we kill and wait for the shell, not the
process spawned by the shell. And so the child process, even if it
eventually exits, will hang around as a zombie forever. And this is
true of most (all?) shells: bash, dash, etc.
So we are not really accomplishing our goal in the first place.
2. Not all shells will exit immediately upon receiving a signal. In
particular, mksh will wait for its children to exit (but not
actually propagate the signal to them!) leaving us with a potential
deadlock: git is wait()ing on mksh, which is wait()ing on a child
process, but that child process is waiting on git to produce more
input (or EOF) over a pipe.
You can see several examples of this deadlock in the test suite,
for example by running:
make SHELL_PATH=/bin/mksh
cd t
./t5702-protocol-v2.sh
Because this is a regression for mksh users, and because we did not
achieve our goal even with other shells, let's revert the commit for
now. If there is a more clever way of doing the same thing, we can
consider applying it separately on top (or do nothing and just accept
the zombies and rely on PID 1 to reap them).

As writing version 2 MIDX files by default breaks older versions of
Git and its reimplementations, use V2 only when necessary.
* jk/midx-write-v1-by-default:
MIDX: revert the default version to v1
We introduced midx version 2 in b2ec8e90c2 (midx: do not require packs
to be sorted in lexicographic order, 2026-02-24) and now write it by
default. The rationale was that older versions should ignore the v2 midx
and fall back to using the packs (just like we do for other midx
errors). Unfortunately this is not the case, as we have a hard die()
when we see an unknown midx version.
As a result, writing a midx with Git 2.54-rc2 puts the repository into a
state that is unusable with Git 2.53. And this midx write may happen
behind the scenes as part of normal operations, like fetch.
Let's switch back to writing v1 by default to avoid regressing the case
where multiple versions of Git are used on the same repository.
There is one gotcha, though: the v2 format is required for some new
features, like midx compaction, and running "git multi-pack-index
compact" will complain when asked to write a v1 index. The user must set
midx.version to "2" to make the feature work.
So instead of always using v1, we'll base the default on whether the
requested feature requires v2. That does mean that running midx
compaction will create a repository that can't be read by older versions
of Git. But we never do that by default; only people experimenting with
the new feature will be affected.
We have to adjust the test expectation in t5319, since it will now
generate v1 files. And our "auto-select v2" is covered by the tests in
t5335, which continue to check that compaction works without having to
set midx.version manually (and also explicitly check that asking for v1
with compaction reports the problem).

The glossary entry is a list of terms and their definitions, so
multi-paragraph definitions need "+" continuation lines to indicate
that they are part of a single entry.
When an entry contains a sub-list (say, a bulleted list), the final "+"
may become ambiguous: is it connecting the next paragraph to the final
entry of the sub-list, or to the original list of definition paragraphs?
Asciidoc generally connects it to the former, even when we mean the
latter, and you end up with the next paragraph indented incorrectly,
like this:
glob
...defines glob...
Two consecutive asterisks ("**") in patterns matched
against full pathname may have special meaning:
- ...some special meaning of **...
- ...another special meaning of **...
- Other consecutive asterisks are considered invalid.
Glob magic is incompatible with literal magic.
That final "Glob magic is incompatible" paragraph is in the wrong spot.
It should be at the same level as "Two consecutive asterisks", as it is
not part of the final "Other consecutive asterisks" bullet point.
The same problem appears in several other spots in the glossary.
Usually we'd fix this by using "--" markers, which put the sub-list into
its own block. But there's a catch: in some of these spots we are
already in an open block, and nesting open blocks is a problem. It seems
to work for me using Asciidoc 10.2.1, but Asciidoctor 2.0.26 makes a
mess of it (our intent to open a new block seems to close the old one).
Fortunately there's a work-around: when using a "+" list-continuation,
the number of empty lines above the continuation indicates which level
of parent list to continue. So by adding an empty line after our
unordered list (before the "+"), we should be able to continue the
definition list item.
But asciidoc being asciidoc, of course that is not the end of the story.
That technique works fine for the "glob" and "attr" lists in this patch,
but under the "refs" item it works for only 1 of the 2 lists! I can't
figure out why, and this may be an asciidoctor bug. But we can work
around it by using "--" open-block markers here, since we're not
already in an open block.
So using the extra blank line for the first two instances, and "--"
markers for the second two, this patch produces identical output from
"doc-diff HEAD^ HEAD" for both --asciidoctor and --asciidoc modes.
