ci: update status when action triggered by issue comment - #526
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 <rmeggins@redhat.com>

Do not execute a fork PR head in these privileged workflows.
A fork PR can supply malicious test configuration. A trusted issue_comment then causes these workflows to check out and execute that code in jobs with statuses: write. Reject fork heads before checkout, or move test execution to an unprivileged pull_request workflow.

GitHub Actions issue_comment event github.sha default branch last commit official documentation
💡 Result:
When a GitHub Actions workflow is triggered by the issue_comment event, the GITHUB_SHA environment variable defaults to the last commit on the default branch of the repository [1][2]. This occurs because the issue_comment event is decoupled from any specific commit associated with a pull request, and workflows for this event must exist on the default branch to be triggered [1][3]. Because GITHUB_SHA does not point to the commit associated with a pull request (when the comment is made on a PR), you cannot rely on it if your workflow needs to operate on the specific code state of that pull request. To obtain the correct commit SHA or branch for a pull request in this context, you typically need to use the GitHub API (e.g., via the github-script action) to query the pull request data using the information provided in the event payload (github.event.issue.pull_request.url or the pull request number) [3]. Key technical points: - Default Behavior: GITHUB_SHA and GITHUB_REF reflect the default branch [1][2]. - Workflow Requirement: The workflow file must exist on the default branch to be triggered by the issue_comment event [1][2]. - Context: You can access the pull request metadata via the github.event context to resolve the correct head SHA if needed [1][3].

GitHub CLI gh api exit status failed request command substitution official manual
💡 Result:
The GitHub CLI command gh api adheres to standard exit code conventions, where a successful command returns an exit code of 0 and a failed request (such as a 4xx or 5xx HTTP response) results in a non-zero exit code, typically 1 [1][2][3]. When using command substitution (e.g., result=$(gh api...)), a failed gh api request will cause the command to exit with a non-zero status [1]. If your script relies on checking whether the command succeeded, it is best practice to handle the exit status directly rather than relying on the output content [4]. Common issues and patterns include: 1. Handling Failures in Scripts: Since gh api exits with a non-zero status on failure, you can use standard shell constructs like if statements or the || operator to manage errors without breaking your script's execution flow [5]. For example: if! result=$(gh api /some/endpoint); then echo "Request failed" result="" fi 2. Error Output Behavior: Be aware that when gh api encounters an HTTP error, it may write the error response body to standard output (stdout) or standard error (stderr) depending on the context [4][6]. This can lead to unexpected behavior if your script logic incorrectly infers success based on the presence of output [4]. 3. Special Cases: Some requests, such as those using -X HEAD, may produce specific errors like "unexpected end of JSON input" if the target resource does not exist, but they still return a non-zero exit code [7]. If you need to ensure a script continues despite a failed request, explicitly handling the exit code as shown above is the recommended approach [4][5].

Guard the PR SHA lookup before applying the fallback.
If gh api fails in the Get head sha of the PR step, the script still writes an empty head_sha because it does not use set -e or check the command status. The job output then selects github.sha, which points to the default branch for issue_comment events. Checkout and commit-status steps can therefore target an unrelated commit. Fail the lookup or skip the comment path instead of using github.sha for this event.
