GitHub Actions push event branches filter deleted branch deleted true head_commit null workflow
💡 Result:
When a Git branch is deleted in a GitHub repository, a push event is triggered for the default branch, which can inadvertently cause workflows configured for that branch to run [1][2][3]. Key Technical Details: 1. Push Event Behavior: When you delete a branch, the push event's payload includes "deleted": true [2][3]. During this specific event, the head_commit field in the webhook payload is set to null because there is no new commit associated with the deletion—the repository state simply reverts to the current tip of the default branch [4][2][3]. 2. Filtering Deleted Branches: - To prevent workflows from running on these "deleted branch" push events, you can use a conditional job or step in your workflow file. You can check the deleted property in the event payload [3]. - Example: Add an if condition to your job to skip execution when a branch deletion occurs: yaml jobs: build: if: ${{ !github.event.deleted }} runs-on: ubuntu-latest steps: - run: echo "This job will not run on branch deletion." 3. Separate Trigger for Deletions: - If your goal is to perform tasks specifically when a branch is deleted (e.g., cleaning up resources), use the delete event trigger instead of relying on the push event [2][5]. - Note that the delete event workflow must exist on the default branch to trigger [6][5][7]. - You can filter the delete event to respond only to branches using: yaml on: delete: jobs: cleanup: if: github.event.ref_type == 'branch' runs-on: ubuntu-latest steps: - run: echo "Branch ${{ github.event.ref }} was deleted." In summary, the push event triggers for branch deletions with a null head_commit and deleted: true. You should use conditional logic (!github.event.deleted) to filter these out of standard push workflows or use the dedicated delete event for cleanup tasks [8][3].

🌐 Web query:
site:docs.github.com/en/actions/reference/workflows-and-actions/events-that-trigger-workflows push deleted branch head_commit branches filter
💡 Result:
The terms provided relate to configuring GitHub Actions workflows rather than a specific Git command sequence. In the context of GitHub Actions, the branches filter is used within a workflow file to limit which branches trigger the execution of that workflow upon a push event [1]. For example, to configure a workflow to run only when a push occurs on specific branches, you define the branches filter as follows [1]: on: push: branches: - 'main' - 'releases/' Regarding your query about deleting a branch and head commits: when a branch is deleted in a repository, the SHA associated with the workflow run for that push event reverts to the default branch of the repository [1]. Additionally, you can target the head of a pull request within a workflow using context variables such as github.head_ref or github.event.pull_request.head.sha [1].

"delete a branch" "push event" "head_commit" GitHub Actions branches
💡 Result:
When a branch is deleted on GitHub, it can trigger either a delete event or a push event, depending on how your repository's webhooks or workflow triggers are configured [1][2][3]. 1. The delete event: If you use the delete trigger in your workflow (on: delete), GitHub Actions will run the workflow when a Git reference (branch or tag) is deleted [1][4]. The head_commit context is not applicable for this event [1]. Within the workflow, you can access the name of the deleted branch using github.event.ref and filter for branches specifically using github.event.ref_type == 'branch' [5][4][6]. 2. The push event: Deleting a branch also generates a push event where the 'after' SHA is 0000000000000000000000000000000000000000 and the 'deleted' flag in the payload is set to true [2][3]. In this scenario, the head_commit object in the GitHub Actions context is typically null [7][3]. If your workflow is configured to run on push events, it may still trigger unless you explicitly add logic to ignore events where deleted is true [2][3]. To handle these scenarios, it is recommended to use the delete event for specific branch-deletion tasks, using the github.event context to identify the deleted reference [5][4]. If you are relying on push triggers, ensure your workflow steps check for the branch deletion payload state to prevent errors [2][3].

Exclude deleted branch push payloads.
A branch deletion can produce a push payload with deleted: true and head_commit: null. branches: ['**'] does not exclude it, so the enabled notify job can send an incorrect notification.
Add github.event.deleted != true to the job condition.
