ci: exercise credential helpers

2025-02-20T15:49:52Z

Wire up credential helpers in our CI runs so that we can rest assured that they compile and (if tests are available) function correctly. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

ci: fix propagating UTF-8 test locale in musl-based Meson job

2025-02-20T15:49:52Z

The musl-based Meson job is supposed to explicitly specify the UTF-8 locale used for testing, which has been introduced with 84bb5eeace7 (ci: switch linux-musl to use Meson, 2025-01-28). That commit had two issues though: - We continue to refer to "linux-musl", even though the job has been renamed in the same commit to "linux-musl-meson". - We use the wrong option name to specify the locale. This was not noticed though due to the first issue. Fix both of these issues by fixing both the job and option naems. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

Merge branch 'ps/3.0-remote-deprecation'

2025-02-03T18:23:33Z

Following the procedure we established to introduce breaking changes for Git 3.0, allow an early opt-in for removing support of $GIT_DIR/branches/ and $GIT_DIR/remotes/ directories to configure remotes. * ps/3.0-remote-deprecation: remote: announce removal of "branches/" and "remotes/" builtin/pack-redundant: remove subcommand with breaking changes ci: repurpose "linux-gcc" job for deprecations ci: merge linux-gcc-default into linux-gcc Makefile: wire up build option for deprecated features

ci: switch linux-musl to use Meson

2025-01-28T21:03:23Z

Switch over the "linux-musl" job to use Meson instead of Makefiles. This is done due to multiple reasons: - It simplifies our CI infrastructure a bit as we don't have to manually specify a couple of build options anymore. - It verifies that Meson detects and sets those build options automatically. - It makes it easier for us to wire up a new CI job using zlib-ng as backend. One platform compatibility that Meson cannot easily detect automatically is the `GIT_TEST_UTF8_LOCALE` variable used in tests. Wire up a build option for it, which we set via a new "MESONFLAGS" environment variable. Note that we also drop the CC variable, which is set to "gcc". We already default to GCC when CC is unset in "ci/lib.sh", so this is not needed. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

ci: merge linux-gcc-default into linux-gcc

2025-01-22T20:28:27Z

The "linux-gcc-default" job is mostly doing the same as the "linux-gcc" job, except for a couple of minor differences: - We use an explicit GCC version instead of the default version provided by the distribution. We have other jobs that test with "gcc-8", making this distinction pointless. - We don't set up the Python version explicitly, and instead use the default Python version. Python 2 has been end-of-life for quite a while now though, making this distinction less interesting. - We set up the default branch name to be "main" in "linux-gcc". We have other testcases that don't and also some that explicitly use "master". - We use "ubuntu:20.04" in one job and "ubuntu:latest" in another. We already have a couple other jobs testing these respectively. So overall, the job does not add much to our test coverage. Drop the "linux-gcc-default" job and adapt "linux-gcc" to start using the default GCC compiler, effectively merging those two jobs into one.

ci: remove stale code for Azure Pipelines

2025-01-10T17:15:39Z

Support for Azure Pipelines has been retired in 6081d3898f (ci: retire the Azure Pipelines definition, 2020-04-11) in favor of GitHub Actions. Our CI library still has some infrastructure left for Azure though that is now unused. Remove it. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

ci: stop special-casing for Ubuntu 16.04

2025-01-10T17:15:38Z

With c85bcb5de1 (gitlab-ci: switch from Ubuntu 16.04 to 20.04, 2024-10-31) we have adapted the last CI job to stop using Ubuntu 16.04 in favor of Ubuntu 20.04. Remove the special-casing we still have in our CI scripts. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

gitlab-ci: add linux32 job testing against i386

2025-01-10T17:15:38Z

Add another job to GitLab CI that tests against the i386 architecture. This job is equivalent to the same job in GitHub Workflows. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano
