| # Runs all automations related to PR events. | |
| # | |
| # See `issue_automations.yml` for the corresponding implementation for issues. | |
| # | |
| # The automations for PR events are a little more complex than those for issues | |
| # because PRs are a less secure environment. To avoid leaking secrets, we need | |
| # to run automations with code as it appears on `main`. | |
| # | |
| # `pull_request_target` serves this purpose but there is no corresponding | |
| # `_target` version for `pull_request_review`. So we take this roundabout | |
| # approach: | |
| # | |
| # This workflow waits for the `pr_automations_init.yml` workflow to complete and | |
| # then uses its exports to run automations from main, with access to secrets. | |
| # | |
| # ...continued from `pr_automations_init.yml` | |
| # | |
| # 4. This workflow runs after `pr_automations_init.yml` workflow completes. | |
| # 5. It downloads the artifacts from that workflow run. | |
| # 6. It extracts the JSON file from the ZIP to `/tmp`. | |
| # 7. It runs the automations as a script, which can access secrets. | |
