The first publish spent 9 min 42 s in the download action for the 4.6 GB
stable release; the 11.5 GB edge release would not have fitted in the
job's 45 minutes. GitHub's artifact storage limits each connection to a
few megabytes a second, and the action uses few.
An artifact is one zip at a signed address. test/vm-image/nightly-fetch
asks the API for that address and takes it with aria2c over 16
connections, checks the size and unpacks it. The same 4.6 GB artifact
came down in 123 s that way. The publish job gets actions: read for it,
and checks out test/vm-image for the script.
test/unit/nightly-test.sh plays the network with stand-ins: the newest
artifact of a name is the one fetched, a failed download is tried again
with a new address, a wrong size is refused and not unpacked.
actions/checkout v5.0.0 -> v7.0.1
actions/upload-artifact v6.0.0 -> v7.0.2
actions/download-artifact v4.3.0 -> v8.0.2
docker/setup-buildx-action v4.3.0 -> v4.4.1
Each stays pinned to a commit, with the version in its comment.
From the release notes, what the new majors change and why none of it
touches these workflows: download-artifact v5 moved the path of an
artifact fetched by ID, and ours is fetched by name; v8 fails on a
checksum mismatch where v4 said nothing, which is what a publish job
wants. checkout v7 refuses a fork's code under pull_request_target and
workflow_run, and the one workflow_run here checks nothing out. The
Node 24 releases need runner 2.327.1; ours run 2.337.0.
Pinned actions do not update themselves, so .github/dependabot.yml asks
for one grouped pull request a week.
An install test failed 13 seconds in: a public Arch mirror dropped two
signature files while the test container was installing QEMU. The three
test containers now ask mirror.omarchy.org first, with the public
mirrors after it, and try up to three times.
The offline mirror index test compares databases with diff and the
nightly test reads JSON with jq. Neither is in the Arch base image, so
both tests failed in CI while passing on a workstation.
./test/all runs the cidata and orchestrator tests under test/unit/ in a couple of seconds, with no ISO. It runs in an Arch container, where the code it covers runs: the container boots systemd for the tests that ask localectl for its keymaps, and the tests run as an ordinary user. The install test keeps covering everything that needs a VM.
