GitHub Actions workflow syntax push event branch deletion github.event.deleted head_commit null official documentation

💡 Result:

In GitHub Actions, the push event is triggered not only when commits are pushed, but also when a branch or tag is deleted [1]. When a branch is deleted, the push event payload includes a deleted field set to true, and the head_commit object is null [1]. Because head_commit is null during a branch deletion, workflows that reference github.event.head_commit (e.g., to access commit messages or metadata) will fail if they do not account for this state. To handle branch deletions gracefully in a workflow triggered by a push event, you can use a conditional if statement to skip jobs or steps when github.event.deleted is true [2][3][4]. Example syntax to prevent execution on branch deletion: jobs: build: if: ${{!github.event.deleted }} runs-on: ubuntu-latest steps: - run: echo "This job will not run on branch deletion." Alternatively, if you need to perform specific logic when a branch is deleted, you can explicitly check for that event type [2]: jobs: on-delete: if: ${{ github.event.deleted }} runs-on: ubuntu-latest steps: - run: echo "Branch ${{ github.event.ref }} was deleted." If your workflow requires specific commit information, it is recommended to always verify that github.event.head_commit is not null before accessing its properties, or use the !github.event.deleted check to ensure the code only runs on standard push operations [3][4].

Citations:

Exclude branch-deletion events from the notification job.

When PUSH_EMAIL_ENABLED is true, a branch-deletion push can reach notify because branches: ['**'] does not exclude deletions. The email body then receives a null github.event.head_commit and has no commit message.

Add && !github.event.deleted to the job condition.

In @.github/workflows/push-email-notify.yml at line 15, Update the notify job
condition in the workflow so it also requires github.event.deleted to be false,
while preserving the existing PUSH_EMAIL_ENABLED and branch 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.

Microsoft 365 SMTP client submission smtp.office365.com port 587 STARTTLS AUTH PLAIN official documentation

💡 Result:

To use Microsoft 365 SMTP client submission, you must configure your application or device using the following parameters: - SMTP Server: smtp.office365.com [1][2] - Port: 587 (recommended) or 25 [1][2] - Encryption: STARTTLS (requires TLS 1.2 or 1.3) [1][2] - Authentication: Modern Authentication (OAuth 2.0) is the recommended standard [1][2]. Basic Authentication (username and password) has been deprecated for SMTP client submission [3][4]. Important Configuration Notes: 1. SMTP AUTH Requirements: SMTP AUTH must be enabled for the specific mailbox being used [5][6]. By default, it is often disabled for new Microsoft 365 tenants and when security defaults are enabled [5][7]. It can be enabled or disabled at the tenant level or overridden per mailbox in the Microsoft 365 admin center (under Users > Active users > Manage email apps) or via Exchange Online PowerShell using Set-CASMailbox [5][6]. 2. Security Defaults: If security defaults are enabled in your Microsoft Entra ID (formerly Azure AD), SMTP AUTH is disabled globally [5][6]. To use SMTP AUTH, security defaults must be disabled [5]. 3. Authentication Method: While some configurations may historically have accepted basic authentication, Microsoft has moved toward requiring Modern Authentication (OAuth 2.0) for all Exchange Online protocols [3][4]. Devices or applications that cannot support OAuth 2.0 may face significant connectivity issues or be blocked by security policies [1][4]. 4. Hostname: Always use the DNS name smtp.office365.com [1][2]. Do not use an IP address, as these can change [1][2]. For further guidance, consult the official Microsoft documentation on setting up multifunction devices or applications for Microsoft 365 [1][2] and managing SMTP AUTH settings [5][6].

Use an SMTP action that supports the configured provider.

If these secrets target Microsoft 365, this step fails because Microsoft 365 uses STARTTLS on smtp.office365.com:587, while secure: true selects implicit TLS and the action does not implement STARTTLS. The action also supports only AUTH PLAIN credentials, not OAuth.

In @.github/workflows/push-email-notify.yml at line 42, Update the email
notification step using smtp-notify-action so it supports the configured
Microsoft 365 provider: use an action with STARTTLS support for
smtp.office365.com:587 and authentication compatible with the configured
credentials, replacing the current hyperpolymath/smtp-notify-action reference
while preserving the existing notification behavior.
