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

💡 Result:

In GitHub Actions, the push event is triggered when a branch is deleted [1][2]. When this happens, the webhook payload reflects the deletion with deleted: true [1][3], and the head_commit object is typically null because no new commit is being pushed [3]. Because the push event fires for both standard code pushes and branch deletions, workflows configured to run on push will execute on deletion events unless explicitly filtered [2][4][5]. To prevent your workflow from running during a branch deletion, you can use a conditional check in your job or step configuration [2][4][5]: if: ${{!github.event.deleted }} This conditional verifies that the push event is not a deletion, effectively bypassing the logic for deleted branches [4][5][6]. If you specifically need to handle branch deletions in a separate workflow or job, you can use the delete event instead [7][2]. Note that for delete events, github.event.ref contains the branch or tag name, and github.event.ref_type specifies whether it was a branch or tag [8][2]. Unlike the push event, the delete event is designed explicitly for these occurrences [7][2]. Summary of Key Differences: - Push Event: Triggered on branch creation, modification, and deletion [1][2]. Use !github.event.deleted to filter out deletions [4][6]. - Delete Event: Triggered specifically when a branch or tag is deleted [7][1]. Use if: github.event_name == 'delete' to isolate this logic [2]. - head_commit: On a deletion push event, head_commit is null [3]. Avoid referencing github.event.head_commit without checking for its existence to prevent workflow failures [9].

Citations:

Exclude branch-deletion push events.

branches: ['**'] does not exclude deleted branches. A deletion push has deleted: true and head_commit: null, so this job can send an email with an empty Head msg. Add !github.event.deleted to the job condition.

GitHub Actions concurrency default multiple workflow runs can run concurrently official documentation

💡 Result:

By default, GitHub Actions allows multiple workflow runs and jobs to execute concurrently [1][2]. There is no automatic restriction on the number of concurrent runs for a workflow unless you explicitly configure the concurrency keyword [3][4]. When you use the concurrency keyword to define a concurrency group, you can restrict execution so that only one job or workflow run within that group is active at any time [3][1]. The default behavior when using a concurrency group is: 1. Pending jobs: Only one job or workflow run is allowed to be in a pending state at a time [3][4]. 2. Cancellation: If a new run is triggered while another run in the same group is already in progress or pending, the existing pending run is automatically canceled to make room for the new one [3][5]. You can modify this default behavior by using the queue property [4][6]. For instance, setting queue to max allows up to 100 jobs or workflow runs to wait in the concurrency group rather than being canceled [3][4]. Additionally, you can use the cancel-in-progress property to control whether currently running jobs are canceled when a new job in the same group is triggered [7].

Citations:

Define a concurrency policy for notification bursts.

Each enabled push event can run the notify job and its SMTP action concurrently. timeout-minutes: 5 limits each job; it does not limit concurrent workflow runs. Define an explicit concurrency or rate-limit policy. Set cancel-in-progress: true only if dropping intermediate notifications is acceptable.

In @.github/workflows/push-email-notify.yml at line 24, Define an explicit

do not run without a deliberate limit; configure the workflow’s concurrency
group and cancellation behavior, using cancel-in-progress only if intermediate
notifications may be dropped. Keep the existing notify job timeout unchanged.
