# 09f94c5), now on hyperpolymath/smtp-notify-action: Node-free, the SMTP
# session is Idris2-specified and machine-checked, the binary is Zig-built,
# byte-reproducible, and SHA-256-pinned inside the action itself.

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

💡 Result:

When a branch is deleted, GitHub triggers a push event payload where the head_commit object is null [1][2]. In this scenario, the after SHA in the push payload is typically set to 0000000000000000000000000000000000000000 [2]. Because branch deletion triggers a push event, any workflow configured with on: push may run when a branch is deleted [1][2]. If you wish to prevent your workflow from running during these events, you can add a conditional check to your job using the if keyword to filter out deletions [3]. Example of filtering out branch deletions: jobs: build: runs-on: ubuntu-latest if: ${{!github.event.deleted }} steps: - run: echo "This job will not run if a branch was deleted." Regarding branch filters (on.push.branches), note that they apply to the push event as a whole [4][5]. If you push a deletion of a branch that matches your branch filter, the workflow will still trigger unless explicitly excluded by an if condition [1][2]. The delete event is a distinct event type [4][1], and if you specifically want to react to branch deletions, you should use on: delete in your workflow configuration instead of relying on the push event [3][6].

Guard branch deletions before sending mail.

When PUSH_EMAIL_ENABLED is true, on.push.branches: ['**'] also permits branch-deletion push events. These events set github.event.head_commit to null, so the workflow sends an email with no head message. Add && !github.event.deleted to the job-level if condition.

In @.github/workflows/push-email-notify.yml at line 15, Update the job-level if
condition in the workflow to also require !github.event.deleted, preventing
email notification jobs from running for branch-deletion push events while
preserving the existing PUSH_EMAIL_ENABLED and other conditions.

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.

Confirm SMTP compatibility before completing this migration.

If secrets.SMTP_PORT is 587, secure: true selects implicit TLS instead of STARTTLS, so the connection can fail. The action supports AUTH PLAIN only; providers that require AUTH LOGIN cannot authenticate. Use implicit TLS with AUTH PLAIN on port 465, or retain an action that supports the provider's transport and authentication.

In @.github/workflows/push-email-notify.yml at line 42, Validate the SMTP
provider configuration used by the workflow against the pinned smtp-notify
action: use implicit TLS with AUTH PLAIN only when connecting on port 465, and
otherwise retain or select an action supporting the provider’s required STARTTLS
and authentication mode, including AUTH LOGIN if needed.
