[None][fix] Don't infra-retry deterministic SLURM test failures - #17645
Conversation
On the agent path the SLURM allocation outlives pytest, so the job is still RUNNING when classifySlurmFailure inspects it after a pytest failure. A completed-pytest deterministic failure (tests ran, were re-run via --reruns, and still failed) was therefore relabeled <typed:slurm-job-still-running> and retried -- masking the failure whenever the retry happened to pass, and wasting a full retry when it didn't. Short-circuit such failures (failed_results.xml present, or the rerun-failure error text) to defer to the base classifier, which treats them as UserFailure (no retry). A monitor-lost-contact cut leaves results-timeout.xml / "terminated unexpectedly" instead and still retries. Also teach reusePassedTestResults to scan superseded-results*.xml: a suppressed intermediate attempt renames its result XMLs with that prefix so the build-level junit does not re-ingest them, but its passed tests are still valid to reuse on retry (extract_passed_tests pulls only the passing subset).

WalkthroughJenkins preserves deterministic pytest failures during SLURM failure classification. Prior-attempt result discovery also includes ChangesSLURM test retry handling
Estimated code review effort: 2 (Simple) | ~10 minutes Mergeability Score: 🟡 Moderate · up to The change avoids retrying deterministic SLURM test failures, but its failed-results guard can also suppress retries for monitor-loss timeouts, allowing a transient CI infrastructure failure to remain failed.

… only CodeRabbit: failed_results.xml is unreliable evidence -- generateRerunReport writes it from the first-run results whenever any rerun occurred, even when the rerun passed or the job timed out. Keying the gate on it could suppress a legitimate monitor-lost-contact/timeout retry. Rely solely on the propagated "still failed after rerun attempts" error, which is raised only on a genuine deterministic rerun failure and takes precedence over the timeout path. Drop the dead "Regular tests failed after rerun attempt" check (swallowed by catchError). Signed-off-by: Derek Pitman <dpitman@nvidia.com>

Description
On the agent path the SLURM allocation outlives pytest, so the job is still RUNNING when classifySlurmFailure inspects it after a pytest failure. A completed-pytest deterministic failure (tests ran, were re-run via --reruns, and still failed) was therefore relabeled typed:slurm-job-still-running and retried -- masking the failure whenever the retry happened to pass, and wasting a full retry when it didn't. Short-circuit such failures (failed_results.xml present, or the rerun-failure error text) to defer to the base classifier, which treats them as UserFailure (no retry). A monitor-lost-contact cut leaves results-timeout.xml / "terminated unexpectedly" instead and still retries.
Also teach reusePassedTestResults to scan superseded-results*.xml: a suppressed intermediate attempt renames its result XMLs with that prefix so the build-level junit does not re-ingest them, but its passed tests are still valid to reuse on retry (extract_passed_tests pulls only the passing subset).
