macos-14 was retired on 2 November 2026 and the runner label was no longer
supported, so macos-hosted was cancelled and failed required.
Only Apple silicon and the latest macOS are supported, and a standard hosted
runner is free on a public repository, so:
- macos-hosted runs on macos-latest
- it runs on a pull request that touches the macOS paths, without the label
ci:macos
- it needs only changes and lint, like windows-native-test, and no longer
waits for the KDE VM suites
- macos-selfhosted.yaml, its install-nix input, its path filter, the label
ci:macos-self and the variable MACOS_SELF_HOSTED are removed
A hosted runner of the ubuntu-24.04 pool is not promised nested virtualization, and
3 of the 16 suites of run 42182554717 failed the check of /dev/kvm. rerun-no-kvm.yaml
could not help: a workflow_run workflow runs only from the default branch, where the
file is not, and a run cannot rerun its own failed jobs while it is in progress.
The step "Enable KVM" of the nix action is now the only one that enables KVM
(enable_kvm of install-nix-action is off), runs before the disk and the install,
waits for udev to settle and polls /dev/kvm for 30 seconds instead of testing it
once, 42 ms after an asynchronous udevadm trigger, and prints what tells a missing
device from a rule that was not applied yet. With defer-no-kvm a host without KVM
is an output, not a failure.
_vm.yaml calls _vm-attempt.yaml up to three times: the suites that found no KVM are
listed through the artifacts of the run and run again on new machines, and the last
attempt fails them. vm-fast and vm-slow are calls of it. rerun-no-kvm.yaml is
removed.
The tools of stage 0 are the latest releases, taken from the flake, and the code is changed to satisfy
them, not the other way round: every run says which versions it had, and docs/dev/ci.md says how they
are kept current (the weekly lock update, and nix flake update rust-overlay or nixpkgs in between).
The first stage ran shellcheck, rustfmt, cargo-deny and actionlint as the runner image, the
rust-toolchain rustup and two actions shipped them, and the runner's older shellcheck reported
SC2317 on a trap handler that the flake's does not. hygiene, fmt and deny now run every step in
`nix develop .#hygiene`, so CI and a local run use the same versions.
1.7.7 does not know the hosted Arm Windows runner and reported windows-11-arm as an unknown label.
1.7.12 is the latest release and the version nixpkgs gives `just lint`, so the hygiene job and a
local run now agree.
