📝 SummarySummary by CodeRabbit
WalkthroughThe push-email workflow now runs only for branch pushes. It uses a per-run concurrency group, a five-minute timeout, and ChangesPush email notification
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to Push-email notifications now use a replacement SMTP action, but enabled notifications may fail if the configured provider requires STARTTLS or another authentication mode. The action can also drift if its tag changes, and deleted branches can generate incomplete emails. Resolve these issues before merging. Poem

GitHub Actions push event branch deletion workflow runs github.event.deleted branches filter
💡 Result:
To handle branch deletions in GitHub Actions, you should use the delete event rather than relying on the push event [1][2]. When a branch is deleted, the push event may trigger a workflow run on the repository's default branch, which can lead to unintended behavior [3][4]. The delete event provides a specific way to trigger workflows when a Git reference (such as a branch or tag) is deleted [1]. Key points for implementing a branch deletion workflow: 1. Triggering on Deletion: Use the delete event in your workflow configuration [1]. on: delete: 2. Filtering by Ref Type: The delete event triggers for both branches and tags [1]. To ensure your job only runs when a branch is deleted, use a conditional if filter to check the event type [2][5]: jobs: cleanup: if: github.event.ref_type == 'branch' runs-on: ubuntu-latest 3. Accessing the Deleted Branch Name: When the delete event occurs, standard context variables like GITHUB_REF may point to the repository's default branch [2][6]. To get the name of the branch that was actually deleted, use the github.event.ref context variable [2][6]: steps: - name: Get deleted branch name run: echo "The deleted branch was ${{ github.event.ref }}" Note that for the delete event to trigger, the workflow file must exist on the default branch of your repository [1]. Because the push event also triggers on branch deletions (often running on the default branch), you may also need to add logic to your push-triggered workflows to ignore these events if they are causing unwanted runs [3].

site:docs.github.com webhook push payload deleted head_commit null GitHub
💡 Result:
When a GitHub push webhook event payload contains head_commit: null, it indicates that the branch or tag associated with the push has been deleted [1][2]. The GitHub push event is triggered by various actions, including creating or deleting references (branches or tags) [1]. According to official GitHub documentation, the head_commit field is defined as an object or null [1][3]. When a reference is deleted, there is no "head" commit remaining for that reference, resulting in this field being null in the webhook payload [1][2]. To confirm that the push event was caused by a deletion, you should check the deleted boolean field in the same payload, which will be set to true [1][4].

Exclude deleted branch pushes explicitly.
A deleted branch push payload can have github.event.deleted == true and github.event.head_commit == null. With PUSH_EMAIL_ENABLED == 'true', this job can send an email with an empty Head msg field. Add !github.event.deleted to the job condition.

Verify SMTP provider compatibility before merging.
If secrets.SMTP_HOST and secrets.SMTP_PORT do not identify an SMTPS server that supports AUTH PLAIN, the workflow can fail for every enabled notification. secure: true selects implicit TLS, and STARTTLS is not implemented.

GitHub gh actions-lock v0.0.2 actions.lock enforcement runtime workflow reference
💡 Result:
The GitHub CLI extension gh-actions-lock (currently in technical preview) uses a lockfile located at .github/workflows/actions.lock to manage and verify dependencies for GitHub Actions [1][2]. The lockfile format, currently at schema version v0.0.2, pins actions to specific commit SHAs [2]. Regarding runtime enforcement, it is critical to understand that GitHub Actions' native runner does not automatically read or enforce the actions.lock file during workflow execution [3]. The file serves as a record for the gh-actions-lock CLI tool to verify that the versions used in workflows match the recorded, trusted commit SHAs [1][3]. Because the native platform does not enforce this lockfile at runtime, relying solely on actions.lock with mutable tag references (e.g., @v4) in your workflow files leaves your workflows susceptible to runtime drift if the tag is updated upstream [3]. To achieve true runtime immutability, workflows should use explicit 40-character commit SHAs in their uses: clauses [3]. The gh-actions-lock tool functions as an external validation layer that can be integrated into your CI/CD pipelines to ensure your workflow definitions remain synchronized with the intended locked SHAs [1][4][3]. Summary of Key Points: - Role of actions.lock: It is a tool-maintained record for dependency management and verification, not a natively enforced runtime configuration [3]. - Schema v0.0.2: This is the current lockfile schema version used by the gh-actions-lock CLI [2]. - Enforcement: Enforcement is typically handled by running the gh actions-lock command (e.g., in a CI job) to verify that the current workflow dependencies match the lockfile [1][4]. - Best Practice: For environments requiring strict security, use immutable commit SHAs directly in workflow uses: statements, potentially using the lockfile as a source of truth for these updates [3].

Use an immutable action reference.
GitHub Actions does not enforce .github/workflows/actions.lock during workflow execution. This workflow passes the mutable v0.2.0 tag to the runner. Replace it with the recorded full commit SHA, or enforce the lock before every run.
