GitHub Actions push event deleted branch filter github.event.deleted head_commit documentation

💡 Result:

In GitHub Actions, the push event is triggered not only by code commits but also when a branch or tag is deleted [1]. When a branch is deleted, the push event payload includes specific flags that allow you to filter or detect the deletion within your workflow [1]. Key mechanisms to handle branch deletions in a push event: 1. Detecting the deletion: Within a push event workflow, you can check the context object github.event.deleted to determine if the event was triggered by a branch or tag deletion [1]. - github.event.deleted: This boolean property is true if the push event was a deletion [1]. - github.event.head_commit: When a branch is deleted, the head_commit object in the push event payload may be null or represent the state before the deletion, depending on the specific event context [1]. 2. Filtering in the workflow: You can use a job-level conditional to prevent your workflow steps from running when a branch is deleted. For example: jobs: build: if: ${{!github.event.deleted }} runs-on: ubuntu-latest steps: - run: echo "This step runs only on non-deletion pushes." 3. Accessing the deleted branch name: The standard GITHUB_REF variable during a push event refers to the updated ref (often the default branch after a deletion) [2][3]. To identify the specific branch involved in the event, you can inspect the event payload, though note that for a standard push event, the payload provides the ref that was pushed/deleted [1]. If your goal is specifically to react to deletions, using the delete event is generally more reliable than attempting to filter the push event [2][3]. 4. Using the delete event: For scenarios where you explicitly need to react to a branch being deleted, it is recommended to use the delete event trigger instead of relying on the push event [2][3]. The delete event provides the deleted reference directly via github.event.ref [4][5]. on: delete: branches: - 'main' # optional filtering jobs: cleanup: if: github.event.ref_type == 'branch' runs-on: ubuntu-latest steps: - run: echo "Branch deleted: ${{ github.event.ref }}"

Exclude branch-deletion events from the notification job.

When PUSH_EMAIL_ENABLED is true, branches: ['**'] also matches branch-deletion push events. The notify job then invokes the email action with no normal github.event.head_commit.message. Add github.event.deleted != true to the job condition.

In @.github/workflows/push-email-notify.yml around lines 13 - 15, Update the
notify job’s condition in the push workflow to require github.event.deleted !=
true alongside the existing PUSH_EMAIL_ENABLED check, excluding branch-deletion
events 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.

Use an implicit-TLS SMTP endpoint for this action.

If secrets.SMTP_PORT uses STARTTLS, commonly port 587, this step will fail because secure: true selects implicit TLS and the pinned action does not implement STARTTLS. A provider that supports only AUTH LOGIN is also incompatible because the action uses AUTH PLAIN. Configure an implicit-TLS endpoint, normally port 465, and run one real push test before enabling notifications.
