🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Add a concurrency policy for SMTP sends.

When PUSH_EMAIL_ENABLED is true, this workflow can run for every branch push, but it defines no concurrency group. A burst of pushes can start multiple SMTP sends and recreate the notification storm described in the header. Add a deliberate serialisation or coalescing policy. Choose cancellation carefully because an SMTP send may already be accepted when a run is cancelled. (docs.github.com)

In @.github/workflows/push-email-notify.yml at line 15, Add a GitHub Actions
concurrency policy to the workflow, using a stable group key that serializes or
coalesces push-triggered SMTP notification runs; choose cancellation behavior
that does not interrupt an already accepted SMTP send, while preserving the
existing branch trigger and notification flow.

GitHub Actions push event branches filter branch deletion events github.event.deleted workflow syntax

💡 Result:

In GitHub Actions, the push event includes branch deletion as a triggering activity [1]. When a branch is deleted, GitHub sends a push payload where the deleted property is set to true [1]. Because the push event triggers for both creations and deletions, workflows configured to run on push will execute when a branch is deleted unless explicitly filtered. Workflow Syntax for Filtering Standard branches or branches-ignore filters in the on.push section are designed to filter based on the branch name, but they do not inherently filter out the deletion event itself [2][3]. To prevent a workflow from running when a branch is deleted, you must use a conditional if statement at the job level [4]: jobs: my_job: if: ${{!github.event.deleted }} runs-on: ubuntu-latest steps: - run: echo "This job will not run on branch deletion." Handling Branch Deletion Events If your goal is to trigger a workflow specifically for branch deletions, you should use the delete event instead of push [1]. Note that when using the delete event, the branch has already been removed from the repository, so you cannot check out the code of the deleted branch in the same way you would during a push [5]. Example of a workflow using the delete event: on: delete: jobs: on-delete: if: github.event.ref_type == 'branch' runs-on: ubuntu-latest steps: - name: Handle branch deletion run: echo "Deleted branch: ${{ github.event.ref }}" Summary of key points: - The push event triggers on branch deletion (payload deleted: true) [1]. - Use if: ${{ !github.event.deleted }} in your job to skip workflows during deletions [4]. - Use the delete event if you need to react specifically to the act of a branch being removed [1]. - Workflow filters (branches, tags) target the ref name, not the deletion status [2].

Citations:

Exclude branch deletion events from the notification job.

The push event includes branch deletions, and branches filters do not exclude them. A deletion payload can have head_commit: null. Add && !github.event.deleted to the job condition.

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.
