Description

Temporarily waive 1 failed case(s) on DGX_H100. Opened automatically by auto-waive (draft; a human reviews and merges).

The native main-break detector (native-p3/k3-w12h-fresh12h-nopass-hostclock/1.0.1) reports unittest/_torch/misc/test_guided_decoder_errors.py::test_executor_loop_fails_the_request_once_its_batch_is_synchronized broken on main for DGX_H100: failure signature attributeerror: pyexecutor object has no attribute dense_dwdp_manager, onset 2026-11-09T11:27:26Z, latest failure 2026-11-09T12:00:52Z. Policy native_p3@1.0.0 selected it; https://nvbugs/7068781 tracks the fix. Scope DGX_H100 is the stage prefix that ran the failing test.

• Bug: https://nvbugs/7068781 (details, logs and 7-day test history are in the bug)
• Restore coverage when: Remove this line when https://nvbugs/7068781 is fixed or closed and the test passes on DGX_H100 post-merge; un-waive follows the bug, not the PR.

What to check before merging:

• The bug's test-history links show the cases failing on main, not only on the trigger PR.
• The scope DGX_H100 matches the failing stage and no narrower waiver already exists.
• Nothing else is needed from you after merging: the bug owner removes these lines with the fix.

Test Coverage

Review the incident evidence and selector scope before merging. This proposal does not
establish that main is fixed. Confirm restoration separately after the corrective change.

Dev Engineer Review

The change adds a waiver for the named guided-decoder executor-loop test and links it to NVBUG 7068781. The entry has no full:DGX_H100/ or other platform prefix, so the stated DGX_H100-only scope is not reflected in the waiver list.

QA Engineer Review

tests/integration/test_lists/waives.txt adds a skip entry for unittest/_torch/misc/test_guided_decoder_errors.py::test_executor_loop_fails_the_request_once_its_batch_is_synchronized. The waiver removes coverage of the request-failure behavior after batch synchronization wherever this unqualified entry applies. Coverage verdict: needs follow-up to confirm the failure is fixed and restore the test.

Per-File QA Perspective

• tests/integration/test_lists/waives.txt: Adds an unqualified waiver linked to NVBUG 7068781. The list supports platform-prefixed entries, but this entry does not include a platform prefix.

Waive-only PR. Review result: 0 Blocker, 0 Possibly blocking, 2 Required, 0 Nice to have. I checked that the waive takes effect: the unprefixed unittest/... id matches the collected node id exactly. It skips only the failing test; the other 7 tests in the file pass. It does not hide a product bug, because a real PyExecutor always sets dense_dwdp_manager. There is no overlap with other open PRs or release branches. The first Required item is inline on waives.txt:168; the second is below.

• [Required] The PR description says the waive is scoped to DGX_H100: "Temporarily waive 1 failed case(s) on DGX_H100", the full:DGX_H100/... text block, "Scope DGX_H100", and a restore condition that only checks DGX_H100 post-merge. But waives.txt:168 has no prefix, so it applies to every stage. The unprefixed line is the right one, so please fix the description, not the line. The failure comes from the test's own executor shell, with the CUDA calls mocked, so it does not depend on the GPU. unittest/_torch/misc is also collected by DGX_B200-PyTorch-Post-Merge-1/2 (tests/integration/test_lists/test-db/l0_b200.yml:564, post_merge block; jenkins/L0_Test.groovy:7605-7606). tests/integration/defs/test_list_parser.py:119-120 applies a full:DGX_H100/ prefix only to DGX_H100-* stages. So with the prefix that coderabbitai suggests in its thread on waives.txt:168, the B200 post-merge stages would keep failing with the same AttributeError. Please also change the restore condition to: the test passes on the DGX_H100-PyTorch-* and DGX_B200-PyTorch-Post-Merge-* stages.
