Merge branch 'jc/ci-use-arm64-p4-on-macos'

2025-11-17T15:00:12Z

We replaced deprecated macos-13 with macos-14 image in GitHub Actions CI, but we forgot that the image is for arm64. We have been seeing a lot of test failures ever since. Switch to arm64 binary for Perforce tests. * jc/ci-use-arm64-p4-on-macos: Use Perforce arm64 binary on macOS CI jobs

Use Perforce arm64 binary on macOS CI jobs

2025-11-16T23:11:41Z

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. Helped-by: Koji Nakamaru Signed-off-by: Junio C Hamano

ci: verify minimum supported Rust version

2025-10-15T15:10:17Z

In the current state of our Rust code base we don't really have any requirements for the minimum supported Rust version yet, as we don't use any features introduced by a recent version of Rust. Consequently, we have decided that we want to aim for a rather old version and edition of Rust, where the hope is that using an old version will make alternatives like gccrs viable earlier for compiling Git. But while we specify the Rust edition, we don't yet specify a Rust version. And even if we did, the Rust version would only be enforced for our own code, but not for any of our dependencies. We don't yet have any dependencies at the current point in time. But let's add some safeguards by specifying the minimum supported Rust version and using cargo-msrv(1) to verify that this version can be satisfied for all of our dependencies. Note that we fix the version of cargo-msrv(1) at v0.18.1. This is the latest release supported by Ubuntu's Rust version. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

ci: check for common Rust mistakes via Clippy

2025-10-15T15:10:17Z

Introduce a CI check that uses Clippy to perform checks for common mistakes and suggested code improvements. Clippy is the official static analyser of the Rust project and thus the de-facto standard. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

ci: check formatting of our Rust code

2025-10-15T15:10:17Z

Introduce a CI check that verifies that our Rust code is well-formatted. This check uses `cargo fmt`, which is a wrapper around rustfmt(1) that executes formatting for all Rust source files. rustfmt(1) itself is the de-facto standard for formatting code in the Rust ecosystem. The rustfmt(1) tool allows to tweak the final format in theory. In practice though, the Rust ecosystem has aligned on style "editions". These editions only exist to ensure that any potential changes to the style don't cause reformats to existing code bases. Other than that, most Rust projects out there accept this default style of a specific edition. Let's do the same and use that default style. It may not be anyone's favorite, but it is consistent and by making it part of our CI we also enforce it right from the start. Note that we don't have to pick a specific style edition here, as the edition is automatically derived from the edition we have specified in our "Cargo.toml" file. The implemented script looks somewhat weird as we perfom manual error handling instead of using something like `set -e`. The intent here is that subsequent commits will add more checks, and we want to execute all of these checks regardless of whether or not a previous check failed.

ci: deduplicate calls to `apt-get update`

2025-10-15T15:10:16Z

When installing dependencies we first check for the distribution that is in use and then we check for the specific job. In the first step we already install all dependencies required to build and test Git, whereas the second step installs a couple of additional dependencies that are only required to perform job-specific tasks. In both steps we use `apt-get update` to update our repository sources. This is unnecessary though: all platforms that use Aptitude would have already executed this command in the distro-specific step anyway. Drop the redundant calls.

Merge branch 'ps/ci-avoid-broken-sudo-on-ubuntu'

2025-10-14T05:00:35Z

Our CI script requires "sudo" that can be told to preserve environment, but Ubuntu replaced with "sudo" with an implementation that lacks the feature. Work this around by reinstalling the original version. * ps/ci-avoid-broken-sudo-on-ubuntu: ci: fix broken jobs on Ubuntu 25.10 caused by switch to sudo-rs(1)

ci: fix broken jobs on Ubuntu 25.10 caused by switch to sudo-rs(1)

2025-10-11T17:10:34Z

Ubuntu 25.10 has been released. One prominent change in this version of Ubuntu is the switch to some Rust-based utilities. Part of this switch is also that Ubuntu now defaults to sudo-rs(1). Unfortunately, this breaks our CI because sudo-rs(1) does not support the `--preserve-env` flag. Let's revert back to the C-based sudo(1) implementation to fix this.
