Patrick Steinhardt 6e7e50cc7b setup: stop using `the_repository` in `verify_filename()`
Stop using `the_repository` in `verify_filename()` and instead accept
the repository as a parameter. The injection of `the_repository` is thus
bumped one level higher, where callers now pass it in explicitly.

Patrick Steinhardt 8da5ecdb4d setup: stop using `the_repository` in `is_inside_work_tree()`
Similar as with the preceding commit, `is_inside_work_tree()` determines
whether the current working directory is located inside the worktree of
`the_repository`. Perform the same refactoring by dropping the caching
mechanism and injecting the repository that shall be checked.

Note that, same as in the preceding commit, we're also resolving the
worktree path via `realpath()`. In theory this step is not necessary as
we always set the worktree path via `repo_set_worktree()`, and that
function already resolves the path for us. But resolving the path a
second time is unlikely to matter performance-wise, and it feels fragile
to rely on the repository's worktree path being absolute. We thus
perform the same extra step even though it's ultimately not required.

Patrick Steinhardt ce70cbc294 setup: stop using `the_repository` in `is_inside_git_dir()`
The function `is_inside_git_dir()` verifies whether or not the current
working directory is located inside the gitdir of `the_repository`. This
is done by taking the gitdir path and verifying that it's a prefix of
the current working directory.

This information is cached so that we don't have to re-do this change
multiple times. Furthermore, we proactively set the value in multiple
locations so that we don't even have to perform the check when we have
discovered the repository.

While we could simply move the caching variable into the repository, the
current layout doesn't really feel sensible in the first place:

  - It can easily lead to false positives or negatives if at any point
    in time we may switch the current working directory.

  - We don't call the function in a hot loop, and neither is it overly
    expensive to compute.

Drop the caching infrastructure and instead compute the property ad-hoc
via an injected repository.

Note that there is one small gotcha: we often end up with relative
gitdir paths, and if so `is_inside_dir()` might fail. This wasn't an
issue before because of how we proactively set the cached value during
repository discovery. Now that we stop doing that it becomes a problem
though, which we work around by resolving the gitdir via `realpath()`.

Replace the use of `the_repository` in "setup.c" for all static

Patrick Steinhardt 0a6d29090c 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'
    265 |   __glibc_const_generic (S, const char *, strchr (S, C))
        |   ^
  /usr/include/x86_64-linux-gnu/sys/cdefs.h:838:3: note: expanded from macro '__glibc_const_generic'
    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.

Johannes Schindelin 4bb086cfa2 maintenance(geometric): do release the `.idx` files before repacking
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.

Johannes Schindelin 69ed0e35a7 mingw: optionally use legacy (non-POSIX) delete semantics
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.

Johannes Schindelin 4a6ed9d09f l10n: bump mshick/add-pr-comment from v2 to v3
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.

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.

Johannes Schindelin 6e61245d0a ci: bump actions/github-script from v8 to v9
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.

Johannes Schindelin 3148cf56b1 ci: bump actions/{upload,download}-artifact to v7 and v8
`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.

See also:

- Release notes: https://github.com/actions/upload-artifact/releases
- Compare: https://github.com/actions/upload-artifact/compare/v5...v7

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.

Johannes Schindelin e54194d8ba ci: bump microsoft/setup-msbuild from v2 to v3
The v2 of `microsoft/setup-msbuild` runs on Node.js 20, which GitHub
is phasing out of the Actions runners. v3 is a minimal release whose
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
removed from the runners.

The risk of this bump is very low: v3 contains no functional changes
to the action itself -- it merely adds `msbuild.exe` to `PATH`, with
no change to command-line flags, inputs, outputs, or default tool
resolution. The only precondition is a recent-enough Actions Runner,
which the github.com-hosted runners already satisfy.

Harald Nordgren c07039ebc4 checkout -m: autostash when switching branches
When switching branches with "git checkout -m", the attempted merge
of local modifications may cause conflicts with the changes made on
the other branch, which the user may not want to (or may not be able
to) resolve right now.  Because there is no easy way to recover from
this situation, we discouraged users from using "checkout -m" unless
they are certain their changes are trivial and within their ability
to resolve conflicts.

Teach the -m flow to create a temporary stash before switching and
reapply it after.  On success, the stash is silently applied and
the list of locally modified paths is shown, same as a successful
"git checkout" without "-m".

If reapplying causes conflicts, the stash is kept and the user is
told they can resolve and run "git stash drop", or run "git reset
--hard" and later "git stash pop" to recover their changes.

Harald Nordgren 26e4e50d46 checkout: rollback lock on early returns in merge_working_tree
merge_working_tree() acquires the index lock via
repo_hold_locked_index() but several early return paths exit
without calling rollback_lock_file(), leaving the lock held.
While this is currently harmless because the process exits soon
after, it becomes a problem if the function is ever called more
than once in the same process.

Add rollback_lock_file() calls to all early return paths.

Johannes Schindelin b33bea27a2 t5564: use a short path for the SOCKS proxy socket
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.

René Scharfe 9ff4b5ab1b grep: fix --column --only-match for 2nd and later matches
"git grep --column --only-match" shows the 1-based column number of the
first match on each line, but confusing numbers for further matches.
Example:

   $ echo 123456789012345678901234567890 >file
   $ for d in 1 2 3 4 5 6 7 8 9 0
     do
       git grep --no-index --column --only-matching $d file |
       awk -v FS=: -v l=$d: '{l = l sprintf("%3s", $2)} END {print l}'
     done
   1:  1  2 12
   2:  2  4 14
   3:  3  6 16
   4:  4  8 18
   5:  5 10 20
   6:  6 12 22
   7:  7 14 24
   8:  8 16 26
   9:  9 18 28
   0: 10 20 30

Report the column number of each match instead:

   $ for d in 1 2 3 4 5 6 7 8 9 0
     do
       ./git grep --no-index --column --only-matching $d file |
       awk -v FS=: -v l=$d: '{l = l sprintf("%3s", $2)} END {print l}'
     done
   1:  1 11 21
   2:  2 12 22
   3:  3 13 23
   4:  4 14 24
   5:  5 15 25
   6:  6 16 26
   7:  7 17 27
   8:  8 18 28
   9:  9 19 29
   0: 10 20 30

We need to adjust the test in t7810 as well.  The file it uses has the
following five lines; I add a line highlighting the matches and a ruler
at the bottom here, to make it easier to see that the second "mmap"
indeed starts at column 14:

foo mmap bar
foo_mmap bar
foo_mmap bar mmap
foo mmap bar_mmap
foo_mmap bar mmap baz
