ci: update status when action triggered by issue comment - #233
Conversation
issue comment triggers do not automatically update check status in the PR, so use separate steps to update them, similar to how the tft.yml workflow works. For issue comment workflows, ensure that the head_sha is set early in the workflow and the status is only updated if there is a head_sha. Create a variable for context so it is created in one place and used in several places in the workflow. Ensure that the first steps in the workflow are to get the head_sha and set the status to In Progress. Signed-off-by: Rich Megginson <[email protected]>

Full details: Description checkExplanation The description clearly explains the reason, implementation, and expected result. It does not use the template headings and does not state whether Jira or BZ tickets apply, but the required change information is mostly present. Full details: Docstring CoverageExplanation No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 0 files. (9 skipped: 9 unsupported.) Full details: Description FormatExplanation The PR description does not follow Resolution Rewrite the PR description with the required labeled sections. For example: Cause: Issue-comment-triggered workflows do not automatically update the pull request check status. Consequences: Pull requests do not show the current or final status for these workflow runs. Fix: Resolve the PR

GitHub Actions github.sha issue_comment event default branch commit SHA context documentation
💡 Result:
In GitHub Actions, when a workflow is triggered by the issue_comment event, the GITHUB_SHA and github.sha context variable default to the SHA of the latest commit on the default branch of the repository, not the commit associated with the pull request [1][2][3][4]. Because the issue_comment event runs in the context of the default branch, the actions/checkout action will also default to checking out the tip of the default branch unless explicitly configured otherwise [1][5][6][4]. To work with the actual commit SHA of a pull request when using the issue_comment event, you must manually resolve the correct SHA using the GitHub API [1][3][4]. You can achieve this by querying the pull request information from the event payload: 1. Use the GitHub CLI (gh) within your workflow to fetch the head SHA of the PR associated with the comment [3]: gh pr view ${{ github.event.issue.number }} --repo ${{ github.repository }} --json headRefOid | jq -r '.headRefOid' 2. Use this resolved SHA as the ref input for the actions/checkout action to ensure the correct code is checked out [3][4]: - uses: actions/checkout@v4 with: ref: ${{ steps.your_step_id.outputs.your_sha_output }} Additionally, because workflows triggered by issue_comment run on the default branch context, they do not automatically appear as checks on the pull request. If you need the workflow status to appear on the PR, you must manually create a check run using the GitHub API or an action like set-commit-status-action [1][6].

Fail closed when resolving the PR head SHA.
If gh api fails, the lookup step can emit an empty output because it does not enable set -e or validate .head.sha. The fallback then uses github.sha, which is the default-branch SHA for issue_comment events. Checkout and commit statuses can therefore target the wrong commit.
Make the lookup step fail on API errors and empty .head.sha output before using the fallback.
