| name: Restart Preempted Libc++ Workflow | |
| # The libc++ builders run on preemptable VMs, which can be shutdown at any time. | |
| # This workflow identifies when a workflow run was canceled due to the VM being preempted, | |
| # and restarts the workflow run. | |
| # We identify a canceled workflow run by checking the annotations of the check runs in the check suite, | |
| # which should contain the message "The runner has received a shutdown signal." | |
| # Note: If a job is both preempted and also contains a non-preemption failure, we do not restart the workflow. | |
