# session is Idris2-specified and machine-checked, the binary is Zig-built,
# byte-reproducible, and SHA-256-pinned inside the action itself.

GitHub Actions push event branch deletion github.event.deleted head_commit null branches filter documentation

💡 Result:

When a branch is deleted on GitHub, the push event is triggered for that deletion. In this scenario, the head_commit property in the webhook payload is set to null, and the SHA in the workflow run defaults to the tip of the repository's default branch [1][2][3]. Because this event is technically a push event, it can trigger workflows configured with push triggers [2][4]. To prevent your workflows from running unintentionally during a branch deletion, you can implement a filter in your workflow's conditional logic (the if key) to check for the deletion event [4]. You can filter out these events using the following expression: if: ${{!github.event.deleted }} For more granular control, especially if you need to perform specific cleanup actions when a branch is deleted, you should use the delete event instead of the push event [4][5]. The delete event provides information about the deleted reference directly in the payload [5]: on: delete: jobs: cleanup: if: github.event.ref_type == 'branch' runs-on: ubuntu-latest steps: - name: Handle branch deletion run: echo "The branch ${{ github.event.ref }} was deleted." By using the delete event and filtering by ref_type, you can reliably identify which branch was deleted, avoiding the ambiguity of the push event where head_commit is null and the ref context refers to the default branch [3][5].

Citations:

Exclude branch-deletion events explicitly.

branches: ['**'] does not exclude branch-deletion push events. These payloads can set github.event.deleted to true and github.event.head_commit to null. Add github.event.deleted != true to the job condition.

in the push notification workflow to require github.event.deleted != true, while
preserving the existing branches filter and other conditions.

concurrency:
# Deliberately per-RUN, so no run is ever queued behind another and none is
# ever cancelled. Do NOT "tidy" this into a shared group such as
# ${{ github.workflow }}-${{ github.ref }}. GitHub's workflow-syntax docs:
# "By default, any existing pending job or workflow in the same concurrency
# group will be canceled and the new queued job or workflow will take its
# place." That happens regardless of cancel-in-progress, which governs only
# the RUNNING job. On this workflow it silently loses a notification email,
# with no error anywhere. Every run here reports a DISTINCT commit, so there
# is no redundant work for a concurrency limit to remove.
# The docs also offer `queue: max` (up to 100 pending); not used, because 100
# is still a cap whereas a per-run group needs none.
# Verified with zizmor 1.30.0: deleting this block raises concurrency-limits;
# this form silences it exactly as a shared group would.

Confirm the SMTP transport before enabling this workflow.

secure: true selects implicit TLS and does not negotiate STARTTLS. If secrets.SMTP_PORT targets a STARTTLS-only service, the notification step will fail. Configure an implicit-TLS service, normally on port 465, or use a STARTTLS-capable action.
