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

💡 Result:

When a branch is deleted in a GitHub repository, the push webhook event is triggered with the deleted attribute set to true [1][2]. In this scenario, the head_commit object in the JSON payload becomes null [1][2]. Because branch deletion triggers a push event, any GitHub Actions workflow configured to run on push will be triggered by a deletion unless explicitly filtered. To prevent your workflows from running on branch deletions, you can use a conditional check in your workflow's jobs section. Since branch deletion sets github.event.deleted to true, you can skip the job when this condition is met: jobs: my_job: if: github.event.deleted!= true runs-on: ubuntu-latest steps: - run: echo "This job will not run on branch deletion." Alternatively, if you want to prevent the workflow from triggering entirely based on the event type, note that branches filters in the on: push configuration cannot directly filter out deletions; they only match branch name patterns [3][4]. Therefore, using the if conditional within the job is the standard and most effective way to handle this [5]. If you require a trigger that specifically separates deletions from pushes, you would need to use the delete event instead of (or in addition to) the push event, although this will not help you filter the push event itself [6][1][2].

Citations:

Exclude branch-deletion push events.

branches: ['**'] matches branch refs but does not check github.event.deleted. When enabled, this job can process a branch-deletion payload with no head_commit and send an incorrect notification. Add !github.event.deleted to the job condition.

In @.github/workflows/push-email-notify.yml at line 15, Update the job condition
in the push notification workflow to require github.event.deleted to be false,
preventing branch-deletion payloads without a head_commit from being processed
while preserving notifications for normal branch pushes.

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.

When secure: true, the pinned hyperpolymath/smtp-notify-action@ede1191ef6ff3ac02c4f4d9efdf837ee517e11d7 uses implicit TLS and AUTH PLAIN. It does not implement STARTTLS. If secrets.SMTP_PORT is a standard STARTTLS endpoint such as port 587, the notification step can fail. Confirm that the SMTP provider supports implicit TLS and AUTH PLAIN.

including SMTP_PORT or secure, to match the provider’s STARTTLS or implicit-TLS
requirements before retaining the pinned smtp-notify-action step.
