| name: Check if PR is automergeable | |
| # Triggered on all PRs by | |
| # - completion of CI checks (status events), OR | |
| # - tagging with "automerge" or "automerge-web" labels, OR | |
| # - updates to current PRs | |
| # | |
| # This workflow checks if the PR that invoked the trigger is automergeable. | |
| # A PR is automergeable iff it: | |
| # 1) is labeled "automerge" OR "automerge-web" (originates from web submission) (checked in actions_helpers.py) | |
| # 2) only changes plugins (subdirs of /benchmarks, /data, /models, /metrics) | |
| # 3) passes all tests (Travis and Jenkins). | |
| # If all 3 conditions are met, the "automerge-approved" label is applied to the PR | |
| # (This label triggers the `automerge_plugin-only_prs` workflow to merge the PR.) | |
| # | |
| # If any test fails, the user will be notified by the brain-score email account. | |
| # If the user has already been notified of a test failure and there have been no pushes to the PR, no email will be sent. | |
