deploy.yml was the last file in the repo carrying mutable external references.
Both job container images are now pinned by digest, all three `uses:` by a full
40-hex commit SHA, and the wrangler install by exact version, each with a
version/date comment above the reference.
- build container: klakegg/hugo:ext-alpine (abandoned since 2021, mutable tag)
replaced by the exact alpine 3.21 digest the Dockerfile already pins, with a
pre-checkout `apk add --no-cache nodejs git tar` step, `shell: sh` as the job
default, then script/bootstrap and script/test. One pinned base and one
dependency list now serve both the check build and the deploy build.
- deploy container: node:20 -> node@sha256:8f693eaa... (node 20.20.2 bookworm).
- actions/checkout: v4 -> 11bd7190... (v4.2.2), the same SHA check.yml pins.
- actions/upload-artifact: -> ff15f030... (v3.2.1).
- actions/download-artifact: -> 9bc31d5c... (v3.0.2).
- wrangler: `npm install -g wrangler` -> `wrangler@4.86.0`.
Also drops the dead feat/initial-site push trigger, reindents to 4-space YAML
to match check.yml, and adds `if: github.ref_name == 'main'` to the deploy job
so it can never publish from a branch.
This is the second attempt. The first passed two adversarial reviews, merged,
and broke the deploy, because deploy.yml triggers only on push to main and so
nobody could execute what they were reviewing. This time the workflow was
temporarily triggered on the branch, with the deploy job guarded off, and
iterated against the commit-status API until the build job ran green for real.
Doing that found two independent breaks that review had not:
1. actions/upload-artifact v4 fails on this Gitea Actions instance -- artifacts
v4 is a different wire protocol and it is not served here. Two otherwise
identical branch jobs, one with the v4 upload step and one without, failed
and passed respectively. The issue asked for the v3 -> v4 bump; the
artifact actions instead stay on the v3 line, pinned by SHA, at the exact
commits the mutable @v3 references were already resolving to. Tracked
separately in issue 20.
2. wrangler 4.120.0 requires node >= 22 and refuses to start on the pinned
node 20 container. `npm install` only warns about engines, so the install
step would have passed and the deploy step would have failed. The unpinned
command this replaces was never installing `latest` either: npm resolves a
bare name to the newest version whose engines the running node satisfies,
which on node 20 is 4.86.0. So 4.86.0 is what has actually been deploying
this site, and that is what is pinned. Tracked separately in issue 21.
The temporary branch trigger and the temporary probe workflow used to bisect
this are removed in this commit; the deploy guard is deliberately kept.
Verified: make check and script/cibuild green; the build job observed green on
the branch under act_runner (commit 73f912c, "Successful in 7s"); a probe job
pair rehearsed the deploy job end to end -- same pinned node image, same pinned
download action, same pinned wrangler, real site tarball extracted -- stopping
at `wrangler pages deploy --help` instead of publishing. The real deploy job
remains unexercised: it needs CLOUDFLARE_API_TOKEN and would publish, so it can
only run on main. The main run must still be watched and the live site
confirmed.
