| # This workflow will fetch the PR Labels from the PR Artifact, and write | |
| # the PR Labels into the PR. The workflow is called after the | |
| # "pull_request" trigger (labeler.yml). This "workflow_run" trigger uses a | |
| # GitHub Token with Write Permission, so we must never run any untrusted | |
| # code from the PR, and we must always extract and use the PR Artifact | |
| # safely. See https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=321719166#GitHubActionsSecurity-Buildstriggeredwithworkflow_run | |
