fix(ci): pin third-party actions to full commit SHAs - #82
Merged
Merged
Conversation
The account's Actions policy requires a full-length SHA ref. A tag or branch ref is refused at startup — `startup_failure`, no jobs, "this workflow graph cannot be shown" — so these workflows could not run at all. This resolves each ref to the commit it currently points at and records the ref in a trailing comment, e.g. `actions/checkout@<sha> # v4`. `dtolnay/rust-toolchain` takes its toolchain from the ref itself, so those steps also gained an explicit `with: toolchain:` input; without it, a SHA ref would silently lose the channel. No behaviour is intended to change beyond the pins.

Full details: Description checkExplanation The description explains the purpose and expected behaviour, but it does not follow the required template. It omits the Changes section, the RSR Quality Checklist, Testing, and Screenshots sections. It also does not document the explicit Rust toolchain changes mentioned in the objectives. Resolution Rewrite the description using the repository template. Add a Summary section, list the action and Rust toolchain changes, complete the RSR Quality Checklist, describe the testing performed, and add screenshots or state that they are not applicable.

official gh actions-lock lockfile documentation stale action reference dependency mismatch enforcement
💡 Result:
<search_synthesis>
The GitHub Actions dependency lockfile system is a security and stability feature designed to pin workflow dependencies to verified commit SHAs [1][2]. The system centers on the.github/workflows/actions.lock file, which acts as the authoritative record of the resolved transitive dependency graph for a repository's workflows [1][3]. Key components and enforcement mechanisms include: 1. Lockfile Management: The gh actions-lock CLI extension is the primary tool for generating, maintaining, and verifying these lockfiles [2][4]. It scans workflows, pins actions to exact commits, and ensures the lockfile remains synchronized with the workflow definitions [2]. 2. Enforcement and Mismatches: When a repository is onboarded to the lockfile system, GitHub enforces that all workflow dependencies are present in the lockfile [2]. If a workflow references an action version that is not pinned in the lockfile, or if there is a mismatch between the workflow's referenced ref and the lockfile's recorded commit, the workflow run will fail [2][5][6]. This enforcement occurs before any job starts, often resulting in a startup failure [5][6]. 3. Handling Stale References: If workflow references are updated (e.g., bumping an action version) without re-running gh actions-lock, the lockfile becomes stale [5]. Because the lockfile no longer matches the workflow's requirements, the system rejects the workflow [5]. To resolve this, developers must run gh actions-lock to regenerate the lockfile with the updated pins [2][5][6]. 4. Security Features: The system includes verification to prevent forgeries [2]. It ensures that the recorded SHA exists within the referenced branch or tag, and it blocks redirects or identity mismatches at runtime to mitigate risks such as impostor commit attacks [2]. The authoritative schema and parser for these lockfiles are maintained in the github/actions-lockfile repository, which provides the technical definition used by GitHub's tooling [1][3]. Development is ongoing, and the schema is currently evolving toward a stable v1.0.0 release [1].

Regenerate the actions lockfile for the pinned commit.
.github/workflows/actions.lock records v0.2.0, but the pinned commit is v0.3.0. Lockfile enforcement can reject this workflow before the job starts. This is a workflow availability and lockfile-drift issue, not a data-integrity issue.
Run gh actions-lock instead of editing the generated file. Add # v0.3.0 to this pin to match the repository’s existing SHA-pin comments, or use the commit recorded for v0.2.0.
