📝 SummarySummary by CodeRabbit
WalkthroughThe push-email workflow now runs only for branch pushes. Each run uses an independent concurrency group. The notification job has reduced permissions, a five-minute timeout, and a SHA-256-pinned SMTP action. ChangesPush email notification workflow
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The workflow improves notification isolation and permissions, but branch deletions can still produce emails without commit details when notifications are enabled. Add a deletion-event guard before merge. Poem

In @.github/workflows/push-email-notify.yml:
- Line 42: Update the SMTP notification configuration using
hyperpolymath/smtp-notify-action so secrets.SMTP_PORT points to an implicit-TLS
endpoint, normally port 465, or replace the action with one that supports
STARTTLS; ensure the selected transport matches the configured secure TLS mode
before merge.
- Line 15: Update the job condition in the workflow to require
github.event.deleted != true, preventing branch-deletion push events from
running the notification job while preserving the existing PUSH_EMAIL_ENABLED
and branch conditions.

GitHub Actions workflow syntax push event branches branch deletion github.event.deleted head_commit null
💡 Result:
When a Git branch is deleted, GitHub sends a push webhook event to your repository [1][2]. Because this push event indicates a modification to the repository's references, GitHub Actions workflows configured to trigger on push will execute [3][2]. In this specific scenario, the head_commit property in the github.event context is often null [1][4]. This occurs because the push event payload for a branch deletion does not point to a new commit being added, but rather to the state of the repository after the reference removal [3][1]. Consequently, if your workflow relies on github.event.head_commit (e.g., to access commit messages or changed files), it may fail or trigger errors when a branch is deleted [5][4]. To handle this behavior, you should implement conditional logic in your workflow to safely check for the presence of head_commit or detect the deletion event: 1. Use conditional expressions to bypass steps or jobs if github.event.head_commit is null or if the push is a deletion [2]. 2. Detect deletions explicitly within a push workflow using ${{ github.event.deleted }} which is a boolean in the push payload [1]. Example of handling deletions within a push-triggered job: jobs: build: runs-on: ubuntu-latest if: ${{!github.event.deleted }} steps: - name: Run only on non-deletion pushes run: echo "Processing commit ${{ github.event.head_commit.id }}" Alternatively, if your goal is to explicitly handle branch deletions, you should use the delete event type [3][6]. Note that for the delete event to trigger, the workflow file must exist on your repository's default branch [3][7]. The payload for the delete event provides the branch name via github.event.ref and the reference type via github.event.ref_type [8][2]. on: push: delete: jobs: on-delete: runs-on: ubuntu-latest if: ${{ github.event_name == 'delete' && github.event.ref_type == 'branch' }} steps: - name: Handle branch deletion run: echo "Branch deleted: ${{ github.event.ref }}"

Skip branch-deletion push events.
When github.event.deleted is true, head_commit can be null. If PUSH_EMAIL_ENABLED is true, this job can send a notification without commit data. Add github.event.deleted != true to the job condition.

Confirm the SMTP transport before merge.
If secrets.SMTP_PORT targets a STARTTLS-only service, this action can fail because secure: true selects implicit TLS and STARTTLS is not implemented. Use an implicit-TLS endpoint, normally port 465, or select an action that supports STARTTLS.
