# 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. | |
