# 09f94c5), now on hyperpolymath/smtp-notify-action: Node-free, the SMTP
# 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 branches filter head_commit null workflow syntax

💡 Result:

In GitHub Actions, the push event is triggered when a branch is deleted [1][2]. During a branch deletion, the push event payload is sent with specific indicators: deleted is set to true [3], and head_commit is null [3]. When configuring workflows, branch filters (such as branches or branches-ignore under on: push:) are evaluated against the branch that was deleted [4]. If a workflow is configured to run on a push to a specific branch, it may still be triggered if that branch is deleted, because the event is technically a push event affecting that reference [2]. To prevent a workflow from running specifically when a branch is deleted, or to handle the head_commit: null state, you can use conditional job execution in your workflow YAML [5]: jobs: my_job: if: ${{ github.event.deleted!= true }} runs-on: ubuntu-latest steps: - name: Your step run: echo "This only runs if the branch was not deleted." Alternatively, if you need to react explicitly to branch deletions, use the delete event instead of push [1]. Note that the delete event workflow must exist on the default branch of the repository to be triggered [4][6]. You can filter delete events by branch name using the github.event.ref property within a conditional: on: delete: jobs: on-delete: if: ${{ github.event.ref_type == 'branch' && startsWith(github.event.ref, 'feature/') }} runs-on: ubuntu-latest steps: - run: echo "Branch ${{ github.event.ref }} was deleted." [2]

Exclude deleted branches from the notification job.

branches: ['**'] can match a branch-deletion push event. GitHub sets github.event.deleted to true and github.event.head_commit to null, so the workflow can send an incomplete email. Add github.event.deleted != true to the job condition.

In @.github/workflows/push-email-notify.yml at line 15, Update the notification
job condition in the push workflow to require github.event.deleted != true,
preventing execution 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.

Use an SMTP endpoint compatible with this action.

If SMTP_HOST and SMTP_PORT identify a STARTTLS service, this job will fail because secure: true selects implicit TLS and STARTTLS is not implemented. Confirm that the endpoint uses implicit TLS, normally on port 465, and supports AUTH PLAIN; otherwise retain an action that supports STARTTLS.

In @.github/workflows/push-email-notify.yml at line 42, Update the SMTP
notification job’s endpoint configuration for the
hyperpolymath/smtp-notify-action step so SMTP_HOST and SMTP_PORT target an
implicit-TLS service, normally port 465, with AUTH PLAIN support; if the
configured service only supports STARTTLS, replace or retain an action that
supports STARTTLS instead.
