test_perf_sanity_helpers.py referenced GEN_ONLY_PERF_METRIC_LOG_QUERIES and GEN_ONLY_DEVICE_STEP_TIME_METRICS, renamed to
DEVICE_STEP_TIME_LOG_QUERIES/DEVICE_STEP_TIME_METRICS in #18990. That change also widened DEVICE_STEP_TIME_MODES to include "e2e" and added an end_offsets kwarg to parse_gen_worker_device_step_time, neither of which the tests were updated for.

Dev Engineer Review

The test updates align renamed metrics and the end_offsets parser argument. They add "e2e" coverage and preserve the ctx_only exclusion. Removing seven waivers expands execution scope. Reported A10 PyTorch CI failures require investigation.

QA Engineer Review

tests/unittest/scripts/test_perf_sanity_helpers.py updates parser mocks and assertions for renamed metrics, end_offsets, and device-step-time modes. tests/integration/test_lists/waives.txt removes five performance sanity waivers for bug 6770503 and two LLM API telemetry documentation waivers for bugs 6786176 and 6786197. Related performance tests are present in test-db CI lists. Coverage verdict: needs follow-up because CI reports failures.

Per-File QA Perspective

  • tests/unittest/scripts/test_perf_sanity_helpers.py: Covers device-step-time parsing, metric extraction, minimization, emission modes, gated metrics, and ctx_only. No matching CI or manual-QA list entry is identified.
  • tests/integration/test_lists/waives.txt: Removes seven waiver entries. Verify the five performance tests and two LLM API telemetry documentation tests after unwaiving.

Walkthrough

The performance sanity tests now support optional parser end offsets and use device-step-time collections for metric validation. Coverage includes all configured modes, while ctx_only is checked for metric omission. Obsolete waivers were removed.

Changes

Performance sanity test updates

Layer / File(s) Summary
Parser and metric validation
tests/unittest/scripts/test_perf_sanity_helpers.py, tests/integration/test_lists/waives.txt
The mocked parser records optional end offsets. Metric checks use DEVICE_STEP_TIME_METRICS and DEVICE_STEP_TIME_LOG_QUERIES. Tests cover configured modes, exclude metrics for ctx_only, and remove obsolete waivers.

- Line 1337: Update the test around add_perf_metric_value to cover both “e2e”
and “ctx_only” modes, asserting the actual keys emitted into new_data for each
case rather than deriving expectations solely from DEVICE_STEP_TIME_METRICS.
Preserve the ctx_only omission check and add explicit verification that e2e
emits the expected device-step-time metric keys.
- Around line 842-850: Extend the tests using the parse_device_step_time mock to
pass a non-None end_offsets value, then assert that the same value is recorded
in parse_calls, verifying forwarding through the updated parser contract while
retaining coverage for the default None case.

Approving — the comments below are optional touch-ups, not blockers.

Matches the renames and signature change in test_perf_sanity.py — the end_offsets=record.get("end_offsets") call site at tests/integration/defs/perf/test_perf_sanity.py:2802 makes the None expectation correct. One coverage gap noted inline.

test_perf_sanity_helpers.py referenced GEN_ONLY_PERF_METRIC_LOG_QUERIES
and GEN_ONLY_DEVICE_STEP_TIME_METRICS, renamed to
DEVICE_STEP_TIME_LOG_QUERIES/DEVICE_STEP_TIME_METRICS in NVIDIA#18990.
That change also widened DEVICE_STEP_TIME_MODES to include "e2e" and
added an end_offsets kwarg to parse_gen_worker_device_step_time,

…idening

Parametrize test_add_perf_metric_value_skips_absent_statistics over
DEVICE_STEP_TIME_MODES so it also pins that "e2e" uploads the
gen_worker_per_iter family, not just "gen_only". Rename
test_add_perf_metric_value_omits_the_family_outside_gen_only to
..._outside_device_step_time_modes since gen_only is no longer the
only emitting mode.

Remove the stale waiver entry.

test_add_perf_metric_value_omits_the_family_outside_gen_only was renamed to test_add_perf_metric_value_omits_the_family_outside_device_step_time_modes. The waiver now references no discoverable test and fails validate-test-lists. Remove this obsolete bug 6770503 entry, as required for the fixed performance-sanity-helper waivers.
