GitHub push event deleted branch head_commit null workflow branches filter documentation

💡 Result:

When a branch is deleted on GitHub, the resulting push event payload indicates the deletion with a 'deleted' field set to 'true' [1][2]. In this scenario, the 'head_commit' field in the payload is null, and the 'after' SHA is typically represented by a string of zeros (e.g., '0000000000000000000000000000000000000000') [3][4]. Because GitHub Actions workflows triggered by the 'push' event may inadvertently run when a branch is deleted, users often need to explicitly filter these events [5][3]. Key points regarding GitHub Actions and branch deletions: 1. Workflow Triggers: If you use the 'push' event trigger, your workflow will receive notifications for branch deletions [1][2]. When this happens, the workflow run is typically associated with the repository's default branch rather than the deleted one [6]. 2. Filtering in Workflows: To prevent a workflow from executing during a branch deletion, you can add a conditional check to your job steps using the 'if' property [7]. Example: if: ${{!github.event.deleted }} 3. Explicit 'delete' Event: If your goal is to handle branch deletions specifically, you should use the 'delete' event trigger instead of relying on the 'push' event [1][2]. The 'delete' event provides clear information about the deleted reference via 'github.event.ref' [8][7]. Using the 'branches' filter in your workflow configuration (e.g., 'on: push: branches: [main]') may not effectively prevent the 'push' event from firing for deletions on those branches, as the 'deleted' state is a fundamental attribute of the push event itself [3][7]. Consequently, explicit conditional logic is the most reliable way to manage this behavior [7].

Exclude deleted branches explicitly.

When PUSH_EMAIL_ENABLED is true, the notify job reads github.event.head_commit.message, but a branch-deletion push payload can set head_commit to null. Add a deletion guard to prevent an incomplete notification:

Proposed fix
-    if: ${{ vars.PUSH_EMAIL_ENABLED == 'true' }}
+    if: ${{ vars.PUSH_EMAIL_ENABLED == 'true' && github.event.deleted != true }}

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 v0.2.0 MIGRATION.adoc secure AUTH PLAIN implicit TLS STARTTLS Microsoft 365

💡 Result:

Regarding the query about smtp-notify-action v0.2.0, there is no widely recognized technical project by that specific name (hyperpolymath/smtp-notify-action) in the context of a public migration guide. It is possible that this refers to a private repository, a misremembered name, or a component within a larger system like those used in the hyperpolymath GitHub organization [1][2]. However, the technical challenges mentioned—secure AUTH PLAIN, implicit TLS, STARTTLS, and Microsoft 365 compatibility—are common integration issues [3][4]. When configuring SMTP services with Microsoft 365, consider the following authoritative requirements [5][6][7]: 1. Microsoft 365 Requirements: - Authenticated SMTP must be explicitly enabled in the Microsoft 365 Admin Center for the specific mailbox [3]. - Use smtp.office365.com on port 587 with STARTTLS [6][7]. - Microsoft 365 often prefers AUTH LOGIN over AUTH PLAIN [3]. If your library or action is hardcoded to use PLAIN, it may fail with a 504 5.7.4 error; ensure the client negotiates authentication based on server capabilities [3]. - Modern authentication (OAuth 2.0) is increasingly required [5][4]; basic authentication (username/password) may be disabled by tenant-wide security defaults or Conditional Access policies [5][3]. 2. General SMTP Best Practices: - Implicit TLS (port 465) is generally preferred over STARTTLS (port 587) for security as it avoids the potential for downgrade attacks, though Microsoft 365 standard client submission specifically requires port 587 with STARTTLS [4][6][7]. - Never store credentials in source code; use GitHub Secrets or equivalent environment variables [1][4][8][9]. - If you are encountering migration issues, verify that your client library or action correctly handles the TLS handshake sequence (STARTTLS vs. implicit) and supports the authentication mechanisms advertised by the server [3][4][6].

Verify the SMTP endpoint before enabling this migration.

secure: true selects implicit TLS, normally on port 465, and the action supports only AUTH PLAIN. If the SMTP secrets target STARTTLS on port 587 or Microsoft 365, the step can fail. Confirm endpoint compatibility and run a controlled delivery test before merge.

GitHub Actions secure use full-length commit SHA immutable action reference tag mutable uses

💡 Result:

In GitHub Actions, pinning to a full-length commit SHA is the only way to ensure an action reference is immutable [1][2][3]. While tags (e.g., @v1, @v4) and branches (e.g., @main) are convenient, they are mutable references that can be moved, deleted, or re-pointed by repository maintainers or attackers who gain access to the action's repository [1][4][5][6]. Using a full-length 40-character commit SHA provides several critical security and stability benefits: - Immutability: A commit SHA is content-addressed and cannot be changed without modifying the underlying code [4][7][5]. This prevents supply chain attacks where a compromised tag is updated to execute malicious code [8][3][9]. - Protection against Retargeting: Because SHAs are unique identifiers for a specific commit, workflows remain locked to the verified version of the code, protecting against "tag retargeting" or "tag moving" exploits [8][7][9]. - Enforced Compliance: Organizations can enable repository or organization-level policies that mandate full commit SHA pinning [1][10][5]. When active, these policies will block any workflow that uses mutable tag references, ensuring compliance across the dependency tree, including sub-actions [10][3][5]. Best Practices for Implementation: - Always use the full 40-character commit SHA, never an abbreviated version [4][7]. - Maintain readability and updateability by including the human-readable version as a trailing comment (e.g., uses: actions/checkout@a824008 # v4.2.0) [11][3][7][9]. - Utilize automation tools like Dependabot, Renovate, or specialized CLI tools (such as pinact) to manage and update these pinned SHAs, ensuring security updates are reviewed and adopted deliberately rather than inherited automatically [11][8][3][7]. - For action authors, pinning internal references to full commit SHAs is equally important, as these sub-actions will be checked by the consumers' enforcement policies [5]. While pinning to a tag is a common practice for convenience, it carries inherent risk and should only be done if you fully trust the creator and are aware that the reference can change at any time [1][2]. For production workflows and environments requiring strong security controls, pinning to a full-length commit SHA is the recommended standard [11][10][3].
