| # When pushing branches (and/or updating PRs), we do want to cancel previous | |
| # build runs. We assume they are stale now; and do not want to spend CI time and | |
| # resources on continuing to continue those runs. This is what the concurrency.group | |
| # value lets us express. When using merge queues, we now have to consider | |
| # - runs triggers by commits per pull-request | |
| # we want to cancel any previous run. So they should all get the same group (per PR) | |
| # - runs refs/heads/gh-readonly-queue/<target branch name> (they should all get their | |
| # unique git ref, we don't want to cancel any of the ones in the queue) | |
| # - if it's neither, we fall back to the run_id (this is a unique number for each | |
| # workflow run; it does not change if you "rerun" a job) | |
