breeze ci approve-workflow-runs (run by workflows/auto-approve-workflow-runs.yml) decides whether
to approve an external contributor's CI runs from an estimate of the job-minutes they take. The
numbers live in dev/breeze/src/airflow_breeze/utils/ci_minutes_estimate.py and are medians
measured on recent Tests (AMD) PR runs on public runners.
After you change the CI workflows in a way that adds, removes, splits or resizes jobs (new test groups, a changed matrix, new composite workflows, a move between runner types), refresh the estimates once the change has run on enough PRs, and in any case about once a month:
- Run
uv run dev/calibrate_ci_minutes_estimates.py --since <date>from the repository root with an authenticatedghCLI. Pick a date that covers at least a week of runs after the workflow change. - Copy the medians and fits it prints into the constants of
ci_minutes_estimate.py, and update the "Last calibrated" line next to them. - When you add a new job group to the workflows, add a matching group to both
ci_minutes_estimate.py(with the selective-check output that turns it on) and theJOB_GROUPSpatterns of the calibration script. Unmatched jobs fall into the base group. - Run
uv run --project dev/breeze pytest dev/breeze/tests/test_ci_minutes_estimate.py dev/breeze/tests/test_workflow_run_approval.py -xvs.
The estimates cover public runners only. Self-hosted (RunsOn) runners need their own set once there is enough data from them.
