📝 SummarySummary by CodeRabbit
WalkthroughThe push-email workflow now runs only for branch pushes. It uses per-run concurrency, reduced permissions, a five-minute timeout, and a SHA-256-pinned SMTP notification action. ChangesPush email notification workflow
Estimated code review effort: 3 (Moderate) | ~15–30 minutes Merge Risk: 🟡 Moderate · up to The workflow may fail to send mail with an incompatible SMTP endpoint and can emit incomplete emails for branch deletions. These notification regressions should be addressed or explicitly accepted before merge. Poem

- Line 42: Update the SMTP notification configuration used by the action
referenced in the workflow so SMTP_PORT targets the provider’s documented
implicit-TLS port, preferably 465, while retaining secure: true and ensuring the
selected endpoint supports AUTH PLAIN.
- Line 15: Update the jobs.notify.if condition to require !github.event.deleted,
preventing branch-deletion push events from running the notification job while
preserving the existing conditions.

GitHub Actions push event branch deletion workflow runs github.event.deleted head_commit null
💡 Result:
When a branch is deleted in a repository, GitHub generates a push event [1][2]. In this specific context, the push event payload indicates the deletion by setting deleted to true and the after SHA to 0000000000000000000000000000000000000000 [1][3]. Because the branch no longer exists at the time of the event, the head_commit property in the push event payload is set to null [3]. This behavior is expected, as there is no longer a valid head commit associated with the deleted reference [1][3]. If you need to handle branch deletions in GitHub Actions, you should be aware of the following: 1. Push Event Behavior: If your workflow is configured to trigger on push events, it may run when a branch is deleted [1][4]. Because head_commit is null, any attempt to access properties like ${{ github.event.head_commit.message }} in your workflow will fail or return empty values, potentially causing script errors [5]. 2. Recommended Alternative: Use the delete event trigger instead of relying on push for deletions [1][4]. The delete event is explicitly designed to trigger when a branch or tag is removed [1]. 3. Workflow Filtering: To prevent your push workflows from executing on branch deletions, you can add an if condition to your jobs [4]: if: ${{!github.event.deleted }} By using the delete event, you can access the name of the deleted reference via ${{ github.event.ref }} and the type (branch or tag) via ${{ github.event.ref_type }} [6][4].

🌐 Web query:
site:docs.github.com/en/actions "Deleting a branch or tag will not trigger a workflow"
💡 Result:
The statement that deleting a branch or tag will not trigger a workflow is incorrect. GitHub Actions supports a specific event called delete that runs a workflow when a Git reference (such as a branch or tag) is deleted from a repository [1]. To use this trigger, you must configure your workflow to listen for the delete event [1]: on: delete Important considerations for the delete event include: - The workflow file must exist on the default branch of the repository for the event to trigger [1]. - An event will not be created if more than three tags are deleted at once [1]. - When a delete event triggers a workflow, the GITHUB_SHA and GITHUB_REF environment variables are set to the last commit and the ref of the default branch, respectively [1].

🌐 Web query:
site:docs.github.com/en/actions/reference/workflows-and-actions/events-that-trigger-workflows push event deleted branch head_commit
💡 Result:
When a branch is deleted via a push event in GitHub, the head_commit field in the webhook payload is typically null [1]. In a standard push event, the payload provides details about the commit at the tip of the reference. However, since deleting a branch removes the reference, there is no longer a head commit associated with that specific branch reference in the context of the push operation. Consequently, GitHub sets the head_commit field to null in the payload to reflect that the reference no longer points to a valid commit [1]. For workflows or applications processing these events, it is important to handle this null value to avoid errors, as the operation indicates the removal of a branch rather than an update to a tip commit [1].
Citations:
Exclude branch-deletion events from the notification job.
A branch deletion can trigger this push workflow with github.event.deleted == true and github.event.head_commit == null. The job can then send an email with an empty Head msg. Add !github.event.deleted to jobs.notify.if.

Use an SMTP endpoint that supports implicit TLS and AUTH PLAIN.
With secure: true, this action does not support STARTTLS. A 587/STARTTLS endpoint or an AUTH LOGIN-only provider can cause the notification step to fail. Set SMTP_PORT to 465, or to the provider's documented implicit-TLS port.
