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

💡 Result:

In GitHub Actions, the push event is triggered not only by new commits but also when a branch or tag is deleted [1][2]. When a branch is deleted, GitHub sends a push event payload where deleted is true and head_commit is null [1][3]. Because the branch reference no longer exists at the time of the workflow run, any actions relying on commit-specific data (like head_commit.message or head_commit.id) will fail if they do not account for this state [4][3]. To handle or ignore branch deletion events within a workflow, you can use a conditional if statement to check the github.event.deleted flag [2][4]. Common patterns include: Ignoring branch deletions: You can prevent jobs from running during a branch deletion by adding the following condition to your job: if: ${{!github.event.deleted }} [5][4][6] Filtering by branch name: If you need to filter by branch while also ignoring deletions, you can combine the branches trigger filter with a job-level if condition [7][2]. The branches filter determines if the workflow is triggered for the push; the if condition then determines if the job executes [7]. Example: jobs: my-job: if: ${{!github.event.deleted }} runs-on: ubuntu-latest steps: - run: echo "This runs only on pushes that are not deletions." When specifically responding to branch deletions, use the delete event instead of the push event [1][2]. The delete event is designed for this purpose and provides the name of the deleted branch in the github.event.ref context [8]. Documentation and behavior notes: - The push event payload for a deletion includes deleted: true and head_commit: null [1][3]. - When a branch is deleted, the GITHUB_SHA in the workflow run defaults to the tip commit of the repository's default branch [7][9]. - To identify the branch that was deleted, use the delete event trigger, which provides the branch name directly [1][8].

Citations:

Exclude branch deletion events before sending mail.

When PUSH_EMAIL_ENABLED is true, branches: ['**'] also permits branch deletion push events. These events can have a null head_commit, so the workflow may send a notification with an empty Head msg. Add github.event.deleted != true to the job-level condition.

In @.github/workflows/push-email-notify.yml at line 16, Update the job-level
condition in the push email notification workflow to require
github.event.deleted != true alongside the existing PUSH_EMAIL_ENABLED check,
preventing notifications for branch deletion push events while preserving
notifications for normal 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.

Remove the unnecessary repository-content permission.

This workflow runs only hyperpolymath/smtp-notify-action@v0.2.0 and has no checkout or GitHub API step. Set permissions: {} so the third-party action does not receive unnecessary repository-content access.
