GitHub Actions push event branch filter deleted branch workflow will not run official documentation

💡 Result:

Yes, the GitHub Actions push event can be triggered when a branch is deleted, and it is subject to the standard branch filters defined in your workflow [1][2]. According to official GitHub documentation, the push webhook event includes branch deletions [1]. When a branch is deleted, the workflow may trigger if the deleted branch name matches your configured branches or branches-ignore filters [3][2]. Notably, when this happens, the GITHUB_SHA and GITHUB_REF in the workflow run revert to the repository's default branch [3][2]. Because the push event triggers for deletions, users often find that workflows configured with branch filters (like those targeting specific feature branches) might inadvertently run or behave unexpectedly when those branches are deleted. To specifically handle branch deletions, GitHub recommends using the delete event rather than the push event, as it provides explicit context such as the deleted branch name in the webhook payload (via github.event.ref) [4]. If you need to prevent a workflow from running on a push event that was triggered by a deletion, you can add a conditional check in your workflow job using an expression like if: ${{!github.event.deleted }} [5].

Citations:

Exclude branch deletions explicitly.

push workflows can run when a deleted branch matches branches: ['**']. The deletion payload has head_commit: null, so this job can send an email with an empty Head msg field. Add github.event.deleted != true to the job condition.

GitHub Actions workflow concurrency one running one pending newer pending replaces older cancel-in-progress false documentation

💡 Result:

In GitHub Actions, the cancel-in-progress: false setting does not prevent the cancellation of queued (pending) workflow runs; it only ensures that a currently running job is allowed to complete [1][2]. By default, every concurrency group is limited to at most one running job and at most one pending job [3][1][4]. When a new workflow run enters a concurrency group that already has one job running and one job pending, the existing pending job is automatically cancelled to make room for the new, more recent pending run [3][1][4]. Key takeaways regarding this behavior: - Running Job Protection: When cancel-in-progress is false (the default), the job currently in the running slot is protected from cancellation [1][2]. - Pending Job Behavior: The pending slot acts as a single reservation for the most recent request [1]. Any newer run that arrives while a job is already waiting in the pending slot will cancel that pending job, regardless of whether cancel-in-progress is set to false [1][4]. - Scaling Queues: As of May 2026, you can enable larger queues by adding queue: max to your concurrency configuration [5]. This allows up to 100 jobs to wait in the pending queue instead of being automatically cancelled, permitting them to execute sequentially [6][5]. To avoid unintended cancellations of queued runs, you must either use queue: max for sequential execution or ensure your concurrency group keys are specific enough (e.g., including ${{ github.ref }}) to prevent unrelated runs from contending for the same group slots [7][5][4].

Define a delivery queue for notifications.

This workflow has no concurrency policy, so separate push runs can open SMTP sessions concurrently. timeout-minutes: 5 limits each job only. If every push must be delivered, use a durable queue or a concurrency queue with sufficient capacity; a standard concurrency group can replace pending runs.

In @.github/workflows/push-email-notify.yml at line 23, Add a workflow-level
concurrency group for push notification runs, using a stable group key and
retaining pending runs rather than canceling in-progress delivery jobs.
Configure the policy near the existing timeout-minutes setting so SMTP sessions
are serialized through the notification workflow.
