The ref-only guards allowed a manual workflow run targeting a tag to publish to crates.io, overwrite release Docker tags, and create GitHub releases. Add `github.event_name == 'push'` to all three gates so only an actual tag push can trigger publication, regardless of what ref a dispatch targets.
The global `docker-images` group serialized all pushes but dropped intermediate runs when multiple tag pushes arrived together, since GitHub keeps only one pending run per group. A `v0.12.0` push followed by `v0.12.1` would cancel the queued `v0.12.0` build, leaving that version without an image.

I would not approve this yet. The current head fixes the manual-dispatch-to-tag bypass and the Rust publish/release jobs now require an exact version-tag push, but the Docker workflow still publishes images for malformed v*.*.* tag pushes.
The workflow trigger still admits refs like refs/tags/v1.2.3-rc.1 or refs/tags/v1.2.3foo because on.push.tags: 'v*.*.*' is a glob. In both Docker jobs, Set image tag for metadata treats any tag push as trusted:
if [[ "$GITHUB_EVENT_NAME" == "push" && "$GITHUB_REF" == refs/tags/* ]]; then
tag="${GITHUB_REF#refs/tags/}"
fiThe exact vX.Y.Z regex is only used to decide whether to add latest; it does not prevent docker/metadata-action and docker/build-push-action from pushing the raw malformed tag itself. I reproduced the predicate behavior locally: for push refs refs/tags/v1.2.3-rc.1 and refs/tags/v1.2.3foo, the current script selects those values as valid OCI tags and would still push them, just without latest. That still violates the PR's tag-push-only release boundary and can leave unintended Docker artifacts in the public registry.
Please make Docker tag pushes use the same exact release predicate before publishing (for example, reject/non-publish tag pushes that do not match ^refs/tags/v[0-9]+\.[0-9]+\.[0-9]+$, or make the jobs conditional on that validation). I verified the current head with git diff --check, actionlint on both changed workflows, and the existing GitHub checks are green; this is the remaining blocker.
…X.Y.Z release The v*.*.* trigger glob matches v1.2.3foo and v1.2.3-rc.1 in addition to stable releases. Add a regex guard rejecting non-release tags before the build runs, so a pre-release or malformed tag push fails immediately with a clear error instead of proceeding through the build only to skip publication at the end.

I still would not approve this yet. The previous malformed-tag Docker publishing blocker is fixed on 77a8a68: exact vX.Y.Z tag pushes publish, malformed v*.*.* tag pushes now fail before metadata/build-push, and tag-targeted workflow_dispatch runs take the guarded dev-<sha> path. I also re-ran git diff --check, actionlint on both changed workflows, local predicate simulations for valid/malformed/manual tags, and the exact-head GitHub checks are green.
Remaining blocker: the PR still claims the Docker concurrency change prevents races on latest, but the workflow groups by ${{ github.ref }}. Two different stable version tags therefore run in different concurrency groups while both publish latest. If v1.2.3 and v1.2.4 overlap, whichever build finishes last wins latest, so an older release can still overwrite the newer latest tag.
This is release-integrity relevant because this PR is hardening the publishing boundary and explicitly calls out the latest race mitigation. Please either implement a mechanism that really serializes/guards latest updates across stable release tags, or narrow the PR description/commentary and track that stable-tag latest race as a separate known follow-up instead of presenting it as fixed here. Until that is reconciled, I would keep this as changes requested.
The check_stable step now fetches all tags and compares the pushed ref against the newest vX.Y.Z tag. When v0.12.0 and v0.12.1 are pushed concurrently, only the v0.12.1 build sets is_stable=true and updates `latest`, preventing the slower v0.12.0 run from downgrading the tag.

I still would not approve this yet. The new newest=$(git tag ... | sort -V | tail -1) check reduces one case, but it still decides whether to include latest near the start of each job and stores that decision in steps.check_stable.outputs.is_stable before the expensive build/push work.
That leaves the release-order race open: if the v1.2.3 run starts while v1.2.3 is the newest visible tag, it sets is_stable=true. If v1.2.4 is pushed and published while the older build is still running, the older run does not re-fetch/re-check before docker/build-push-action; it will still push latest from its precomputed metadata and can overwrite the newer release. I reproduced this with a local predicate simulation: old run sees ['v1.2.2', 'v1.2.3'] and enables latest; later new run sees ['v1.2.2', 'v1.2.3', 'v1.2.4'] and also enables latest; if the old build finishes last, latest regresses.
So the current head still does not satisfy the comment/PR claim that overlapping tag pushes cannot leave latest pointing at the older release. Please move the highest-version decision to a serialized promotion point immediately before updating latest (with a fresh tag fetch after acquiring that lock), or otherwise make latest promotion atomic/generation-checked. Version-specific image tags can remain parallel, but the shared latest mutation needs a current check at the mutation boundary.
Verified on current head fa0692b: previous malformed-tag and tag-targeted-dispatch blockers remain fixed, git diff --check passed, actionlint passed for both changed workflows, and exact-head GitHub checks are green.
…both images finish building The check_stable step ran during the build, locking its decision for the duration of a multi-arch build. A newer release tagged while an older build was in progress could be overwritten when the older run finished later and moved `latest` backward. Extract promotion into a dedicated job that runs after both plain and StartOS images exist, refetches tags inside a shared concurrency group, and compares versions at the moment of the move rather than at build start.

Approved on current head 1face8a. The previous blockers are fixed: manual dispatches no longer publish release tags, malformed v*.*.* tag pushes fail before publishing, Rust publish/release are gated on exact version-tag pushes, and latest is now promoted in a separate post-build job with a shared docker-latest-promotion concurrency group and a fresh tag fetch at the mutation boundary. Version-specific image builds can still run per ref, while the shared latest update is serialized and revalidates that the current tag is the highest visible vX.Y.Z before moving latest.
I re-ran git diff --check, actionlint on both changed workflows, local predicate simulations for valid/malformed/manual tags and stale/newer release promotion, and re-read the current PR conversation/threads. Exact-head GitHub checks are green (fmt, clippy, MSRV build, test, build; mutation/mint jobs skipped as configured). I do not see a remaining blocker.

Actionable comments posted: 3 (1 Major, 2 nitpicks)
Reviewed head 1face8a against main (9caa5f9). Two workflow files, no Rust changes; CI on the exact head is green (fmt, clippy, MSRV, test, build). I simulated the set_tag / version-tag predicates locally for push/dispatch × valid/rc/suffixed/latest/vX.Y.Z/newline/leading-dash inputs and they all resolve as the comments in the file describe — that part of the PR is solid. actionlint isn't available on my machine, so I'm relying on the author's and @ermeme's runs for that.
🟠 Major — blocking
promote-latestcan drop a promotion (docker-build-startOs.yml:188). The shareddocker-latest-promotiongroup inherits GitHub's one-pending-job-per-group semantics — the very behaviour the per-ref build group is documented to avoid — and the step only moveslatestwhen the triggering tag is the newest. Three overlapping release pushes can leavelateststale forever with one run shown as cancelled. Concrete sequence and an idempotent fix (promote the highest published version, regardless of trigger) are in the inline comment. Since this is exactly the guarantee the last three review rounds converged on, I'd rather get it right before merge.
🟡 Minor (outside the diff, so not inline)
on.push.tags: 'v*.*.*'(docker-build-startOs.yml:4-6, same inrust.yml:5). GitHub filter patterns support+and[], and they are anchored, sov[0-9]+.[0-9]+.[0-9]+would stopv1.2.3-rc.1/v1.2.3foofrom starting a run at all. Right now every pre-release tag produces a red ❌ run in the Actions tab (the build jobsexit 1by design). Keep the in-script regex as defence in depth, but not triggering is cleaner than triggering-to-fail.
🔵 Nitpicks
- Duplicated
set_tagblock / near-identical build jobs → extract aresolve-tagjob + matrix (inline). promote-latest: full-history checkout and a manualgit fetch --tags— one of the two is redundant (inline).- PR description: "
release.needsis unchanged" — it now includesversion-tag. Trivial, but the description is what ends up in the merge commit.
Verified
- Manual dispatch (branch or tag) can no longer reach

v*.*.*tag pushes fail beforemetadata-action/build-push-action. ✅ - Tag/input values only reach shell through

…solution to a separate job
2 participants
Both release workflows run on tag pushes and on
workflow_dispatch, but neither distinguished the two. A manual run on any branch reachedcargo publish, created a GitHub Release named after the branch, and overwrote thelatestDocker tag.Actions expressions have no regex, so "an exact
vX.Y.Ztag push" cannot be written in anif:on its own. Both workflows resolve it in a job instead, and the tag filters are anchored (v[0-9]+.[0-9]+.[0-9]+) so a pre-release no longer starts a run at all.rust.yml — a
version-tagjob publishesis_release, true only for a push of an exactvX.Y.Ztag, andpublishandreleasegate on it. Aworkflow_dispatchcan target a tag as well as a branch, hence the event check. The build jobs stay reachable fromworkflow_dispatch, so a manual run is still a way to check the cross-compilation before tagging.releasekeeps running independently ofpublish; the only change to itsneedsisversion-tag.docker-build-startOs.yml — the dispatch input defaulted to
latest, so any manual run replaced the published image. Aresolve-tagjob now resolves the tag once for the whole run: a tag push publishes its exactvX.Y.Z, and everything else, a dispatch aimed at a tag included, defaults todev-<short-sha>and rejectslatestorvX.Y.Zas an explicit override. #610 addedcheck_stablefor this, but it only gated the secondlatesttag, not the input default.latestis moved in a separatepromote-latestjob once both images are pushed. Deciding at build time froze the answer for the length of a multi-arch build, so a release tagged during that window could be overwritten by the older run finishing later. The promotion is independent of the tag that triggered it: it moveslatestto the highest version tag whose images are already published. GitHub keeps one pending job per concurrency group, so a burst of releases can have its queued promotion replaced by a later one; because a promotion is only queued once its own images exist, whichever job survives the queue repairslatestfor the ones that were dropped. It also never regresses on a backport run, and a failed build of the highest tag no longer freezes it.Same file, while in there:
