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

💡 Result:

When a branch is deleted on GitHub, the push event is triggered, but the behavior of the GitHub Actions environment changes, often resulting in head_commit being null [1][2][3]. Because the push event includes branch deletions, workflows configured to trigger on push may unexpectedly run when a branch is deleted, which can cause issues such as unintended deployments [4][5]. Key Technical Details: - Push Event Behavior: When you delete a branch, GitHub sends a push event where the deleted property is set to true [2][6]. In this context, GITHUB_SHA and GITHUB_REF typically revert to the default branch of the repository, and the head_commit object in the webhook payload is often null [1][2][3]. - Handling Branch Deletion: You cannot directly filter branch deletions using the standard branches filter in the push event configuration [1][7]. To prevent a workflow from running on branch deletion, you must add a conditional check to your jobs using the github context [5][8]. Recommended Pattern: To filter out deleted branches within a push event, use an if conditional to check the github.event.deleted property [5]. jobs: my_job: runs-on: ubuntu-latest if: ${{!github.event.deleted }} steps: - run: echo "This only runs on actual pushes, not deletions." If you specifically want to handle branch deletions (e.g., for cleanup tasks), it is best practice to use the delete event instead of relying on the push event [2][8]. on: delete: jobs: on-delete: if: github.event.ref_type == 'branch' runs-on: ubuntu-latest steps: - run: echo "Branch ${{ github.event.ref }} was deleted." By using the delete event, you can accurately identify which branch was removed via github.event.ref, whereas in a push event, this information is often obscured because the environment defaults to the repository's main branch [9][8].

Citations:

Exclude branch-deletion events explicitly.

branches: ['**'] does not exclude deleted branches. When github.event.deleted is true, head_commit can be null, but the job still runs when PUSH_EMAIL_ENABLED is true. Add github.event.deleted != true 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 != true in
addition to the existing PUSH_EMAIL_ENABLED check, preventing execution for
branch-deletion events while preserving normal push notifications.
