site:docs.github.com GitHub Actions push event branch deletion branches filter deleted head_commit null
💡 Result:
When a branch is deleted in a GitHub repository, the push event is triggered [1][2]. In this push event payload, the deleted field is set to true, and the head_commit object is null [1][3]. Because a branch deletion does not point to a specific commit (as the ref no longer exists), the payload appropriately reflects this with a null head_commit [1][3]. Regarding GitHub Actions and branch filtering: 1. Behavior: When you delete a branch, the push event is sent, and workflows configured to trigger on push will be evaluated [4][5]. 2. Filtering: If your workflow uses branches or branches-ignore filters, these are evaluated against the Git reference being pushed or deleted [6]. If a workflow is configured to run on a specific branch (e.g., branches: [main]), and that branch is deleted, the workflow may trigger because the deletion is considered a push event to that reference [1][3]. 3. Handling Deletions: If you need to distinguish between a regular push and a branch deletion within a workflow, you can check the github.event.deleted context variable in your steps [1][3]. Note that for dedicated logic related to deletions, the delete event is also available and specifically intended for handling branch or tag deletions, rather than relying on the push event [4][5][1].

Exclude branch-deletion events from email delivery.
When PUSH_EMAIL_ENABLED == 'true', branches: ['**'] also matches branch deletion push events. These payloads set github.event.deleted to true and github.event.head_commit to null, so the job can send an email without a commit message. Add github.event.deleted != true to the job-level if condition.

hyperpolymath/smtp-notify-action ede1191ef6ff3ac02c4f4d9efdf837ee517e11d7 action.yml secure STARTTLS AUTH PLAIN
💡 Result:
The requested string 'hyperpolymath/smtp-notify-action' appears to be a reference to a GitHub workflow implementation used within repositories belonging to the 'hyperpolymath' organization [1][2][3][4]. Specifically, the repositories identified (such as volumod, modshells, and tree-sitter-a2ml) do not use a custom 'smtp-notify-action' but instead utilize the widely-adopted 'dawidd6/action-send-mail' GitHub Action [1][2][3][4]. In these workflows, the configuration typically includes: - secure: true [1][2][3][4] - server_address: ${{ secrets.SMTP_HOST }} [1][2][3][4] - server_port: ${{ secrets.SMTP_PORT }} [1][2][3][4] - username: ${{ secrets.SMTP_USER }} [1][2][3][4] - password: ${{ secrets.SMTP_PASS }} [1][2][3][4] Regarding the security of using 'AUTH PLAIN' with 'STARTTLS': When 'STARTTLS' is correctly implemented, the SMTP connection is upgraded to an encrypted TLS tunnel before any authentication credentials (including 'PLAIN' passwords) are transmitted [5]. This protects the credentials from interception during the session [5]. However, 'STARTTLS' is susceptible to man-in-the-middle (MITM) downgrade attacks, where an attacker intercepts the initial unencrypted communication and prevents the TLS upgrade [5]. To mitigate this, some configurations prefer forcing TLS from the start (e.g., using port 465) rather than relying on 'STARTTLS' negotiation (often on port 587) [5][6]. The 'secure: true' setting in 'dawidd6/action-send-mail' is typically used to enable this secure TLS connection [7].

Verify the SMTP provider configuration before merging.
If secrets.SMTP_PORT is 587, the pinned action uses implicit TLS from the first byte and does not implement STARTTLS, so the notification step can fail. Confirm that the SMTP server uses implicit TLS, normally on port 465, and supports AUTH PLAIN.
