site:docs.github.com GitHub Actions push event deleted true head_commit null branches filter branch deletion

💡 Result:

When a Git branch is deleted, GitHub triggers a push event with the payload parameter deleted set to true [1][2]. In this scenario, the head_commit object in the webhook payload is null because there is no remaining head commit for the deleted reference [1][2]. Regarding how this interacts with branch filters: 1. Triggering Behavior: The push event does trigger workflows when a branch is deleted [3][4]. 2. Branch Filters (branches / branches-ignore): These filters evaluate the reference being deleted [3][5]. If the deleted branch name matches your branches filter (or does not match a branches-ignore filter), the workflow will attempt to run [3][5]. 3. Execution Context: When a branch is deleted, the GITHUB_SHA in the workflow run environment reverts to the latest commit on the repository's default branch [3][6]. If you wish to specifically handle branch deletions separately from standard code pushes, you may consider using the delete event instead, which is specifically designed for when a Git reference (branch or tag) is removed [3][7]. Unlike the push event, the delete event provides specific activity types for deletion and is dedicated to that lifecycle action [7][5]. Note that the delete event only triggers if the workflow file exists on the default branch of the repository [3][6].

Exclude deleted branch payloads from the notification job.

When an enabled branch is deleted, the push event can set github.event.deleted to true and github.event.head_commit to null. The current condition checks only PUSH_EMAIL_ENABLED, so the job can invoke the SMTP action without a commit notification. Add github.event.deleted != true to the condition.

In @.github/workflows/push-email-notify.yml at line 15, Update the notification
job condition in the push workflow to require both PUSH_EMAIL_ENABLED and
github.event.deleted != true, preventing deleted-branch push payloads from
invoking the SMTP action while preserving notifications for enabled, non-deleted
pushes.

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.

hyperpolymath/smtp-notify-action ede1191ef6ff3ac02c4f4d9efdf837ee517e11d7 action.yml AUTH PLAIN STARTTLS secure

💡 Result:

The GitHub organization hyperpolymath does not maintain a custom action named smtp-notify-action [1][2][3][4][5]. Instead, their repositories use a standard pattern for email notifications on push events, employing the widely used community action dawidd6/action-send-mail [1][2][3][4][5]. In these workflows, the configuration typically uses the following inputs to handle secure SMTP connections, including AUTH PLAIN and STARTTLS: - server_address: ${{ secrets.SMTP_HOST }} - server_port: ${{ secrets.SMTP_PORT }} - username: ${{ secrets.SMTP_USER }} - password: ${{ secrets.SMTP_PASS }} - secure: true Setting secure: true in dawidd6/action-send-mail (or the functionally similar step-security/action-send-mail) facilitates a secure connection [1][6][7]. When properly configured, these actions upgrade the connection using STARTTLS before attempting authentication (AUTH PLAIN) to ensure that credentials are transmitted securely [6][7][8][9]. If your SMTP server mandates STARTTLS, ensuring secure: true is configured is the standard approach to satisfy this requirement [8][9].

Confirm SMTP server compatibility before switching actions.

The workflow passes the SMTP secrets to hyperpolymath/smtp-notify-action, which supports AUTH PLAIN and implicit TLS when secure: true; STARTTLS is not implemented. If the server only supports AUTH LOGIN or requires STARTTLS on port 587, notifications can fail. Confirm compatibility or use an action that supports the server’s SMTP contract.
