  • The Containerfile was never exercised by any workflow, so it could break without anyone noticing until someone tried to build it.
  • Running walgit required a Rust and Node toolchain on hand; there was no artifact to just pull and run.
  • canary gives operators a moving tag for the newest trusted main, and sha-<7> gives them something immutable to pin a rollback or a bug report to.
  • The publish is a job in the existing CI workflow rather than a separate one so that needs alone guarantees only a commit that passed both test tiers can ever become canary, with no workflow_run indirection.

Review Change Stack

Walkthrough

The CI workflow adds a validated publish-canary job for pushes to main. It publishes linux/amd64 images to GHCR with canary and immutable sha-<40> tags. The README documents this behavior.

Changes

Canary image publication

Layer / File(s)Summary
Publish canary image
.github/workflows/ci.yml, README.md
The workflow keeps main runs from being cancelled, sets default read permissions, and publishes after build-test and e2e succeed. It generates canary and full-length sha-<40> tags, builds with WALGIT_BUILD_SHA, pushes to GHCR, and documents the tags.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk:🟡 Moderate · up to 2216f

Rerunning the image-publishing job can repoint an existing commit-specific image tag to a different image, undermining reliable rollback and bug reproduction. The tag publication behavior should be corrected before merging.

A cancelled run takes the image publish with it, which would leave some merged
commits with no immutable tag to roll back to. Superseded pull request pushes
are still worth cancelling.

The publish job is the only one holding a token that can write packages, so a
compromised upstream action reaches the registry through it; a seven-character
sha prefix is a namespace that collides, and the collision would move an older
commit's supposedly immutable tag onto a newer image.

The build is not bit-reproducible, so a re-run of an already-published commit
would repoint sha-<40> at a digest nobody chose, and a rollback that pinned it
would land somewhere else than it did the first time.

The build is not bit-reproducible, so a re-run of an already-published commit
would repoint sha-<40> at a digest nobody chose, and a rollback that pinned it
would land somewhere else than it did the first time.

  • The Containerfile was never exercised by any workflow, so it could break without anyone noticing until someone tried to build it.
  • Running walgit required a Rust and Node toolchain on hand; there was no artifact to just pull and run.
  • canary gives operators a moving tag for the newest trusted main, and sha-<7> gives them something immutable to pin a rollback or a bug report to.
  • The publish is a job in the existing CI workflow rather than a separate one so that needs alone guarantees only a commit that passed both test tiers can ever become canary, with no workflow_run indirection.

Review Change Stack

Walkthrough

The CI workflow adds a validated publish-canary job for pushes to main. It publishes linux/amd64 images to GHCR with canary and immutable sha-<40> tags. The README documents this behavior.

Changes

Canary image publication

Layer / File(s)Summary
Publish canary image
.github/workflows/ci.yml, README.md
The workflow keeps main runs from being cancelled, sets default read permissions, and publishes after build-test and e2e succeed. It generates canary and full-length sha-<40> tags, builds with WALGIT_BUILD_SHA, pushes to GHCR, and documents the tags.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk:🟡 Moderate · up to 2216f

Rerunning the image-publishing job can repoint an existing commit-specific image tag to a different image, undermining reliable rollback and bug reproduction. The tag publication behavior should be corrected before merging.

A cancelled run takes the image publish with it, which would leave some merged
commits with no immutable tag to roll back to. Superseded pull request pushes
are still worth cancelling.

The publish job is the only one holding a token that can write packages, so a
compromised upstream action reaches the registry through it; a seven-character
sha prefix is a namespace that collides, and the collision would move an older
commit's supposedly immutable tag onto a newer image.

  • The Containerfile was never exercised by any workflow, so it could break without anyone noticing until someone tried to build it.
  • Running walgit required a Rust and Node toolchain on hand; there was no artifact to just pull and run.
  • canary gives operators a moving tag for the newest trusted main, and sha-<7> gives them something immutable to pin a rollback or a bug report to.
  • The publish is a job in the existing CI workflow rather than a separate one so that needs alone guarantees only a commit that passed both test tiers can ever become canary, with no workflow_run indirection.

Review Change Stack

Walkthrough

The CI workflow adds a validated publish-canary job for pushes to main. It publishes linux/amd64 images to GHCR with canary and immutable sha-<40> tags. The README documents this behavior.

Changes

Canary image publication

Layer / File(s)Summary
Publish canary image
.github/workflows/ci.yml, README.md
The workflow keeps main runs from being cancelled, sets default read permissions, and publishes after build-test and e2e succeed. It generates canary and full-length sha-<40> tags, builds with WALGIT_BUILD_SHA, pushes to GHCR, and documents the tags.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk:🟡 Moderate · up to 2216f

Rerunning the image-publishing job can repoint an existing commit-specific image tag to a different image, undermining reliable rollback and bug reproduction. The tag publication behavior should be corrected before merging.

steps.meta.outputs.tags so existing sha-<40> rollback tags are not overwritten:
detect whether the SHA tag already exists, push it only when absent, and on
reruns push or repoint only canary while preserving the existing SHA tag.

The build is not bit-reproducible, so a re-run of an already-published commit
would repoint sha-<40> at a digest nobody chose, and a rollback that pinned it
would land somewhere else than it did the first time.
