Dev Engineer Review

The PR removes the blanket NVBug 7075896 waiver for unittest/_torch/pyexecutor; the individual PyExecutor waivers remain. The test fixtures now provide the cancellation state and hooks expected by PyExecutor. The overlap-admission test also adapts native Request objects through ExecutorRequest.adapt, aligning the fixture with the current interface.

QA Engineer Review

Two PyExecutor unit-test files were modified, and one test-list file was modified. No test functions or selectors changed. The waiver removal restores coverage for the PyExecutor test directory. Neither modified test file appears in the inspected test-db/ CI or qa/ manual-QA lists. Coverage verdict: needs follow-up because the change removes a broad waiver without listing these unit tests in those integration lists. CPU test results were reported from a pre-sync revision; current-head test status is not available.

Per-File QA Perspective

• tests/unittest/_torch/pyexecutor/test_gen_preemption.py: Covers GEN preemption and lifecycle regressions. The fixture now binds PyExecutor._cancelled_disagg_model_request_ids and supplies canceled_req_ids; the file is not listed in the inspected CI or manual-QA lists.
• tests/unittest/_torch/pyexecutor/test_overlap_admission_lifetime.py: Covers overlap admission and request lifetime. The fixture now binds _cancel_queued_context_requests and adapts native requests; the file is not listed in the inspected CI or manual-QA lists.
• tests/integration/test_lists/waives.txt: Removes the blanket PyExecutor skip for NVBug 7075896. Specific PyExecutor waivers remain, so those tests continue to be skipped.

Description

CPU pyexecutor tests fail before reaching their behavioral assertions because newly added fixtures do not satisfy interfaces already merged into main. The preemption fixture from #21334 omits the cancellation-query method required by #21508. The admission fixture from #21232 uses the native Request constructor contract replaced by the Python request envelope in #21375, and omits the queued-cancellation hook introduced by #21482.

Update the fixtures to bind the real cancellation methods with empty cancellation state and wrap native requests through ExecutorRequest.adapt. Preserve the existing preemption, drafter-lifecycle and sequence-slot ownership assertions, and remove the NVBug 7075896 waiver to restore pyexecutor test coverage.

Test Coverage

CPU-only runs of test_gen_preemption.py, test_overlap_admission_lifetime.py, test_queued_context_cancellation.py and test_request_utils.py passed on x86_64. These runs used an older prebuilt wheel and preceded the final synchronization with main. Waiver validation and applicable pre-commit hooks passed after synchronization; ARM CPU CI remains pending.

Walkthrough

The changes update PyExecutor unit-test fixtures with cancellation-related state and methods, adapt cohort requests from bindings Request objects, and remove the directory-wide integration-test waiver while retaining individual skip entries.

Test fixtures and waiver scope tests/unittest/_torch/pyexecutor/test_gen_preemption.py, tests/unittest/_torch/pyexecutor/test_overlap_admission_lifetime.py, tests/integration/test_lists/waives.txt	The fixtures add cancellation-related state and methods. The overlap-admission test adapts a bindings Request to an ExecutorRequest. The waiver list removes the directory-wide skip entry; individual skip entries remain.

Thanks for restoring the pyexecutor unit tests. Counts: 0 blockers, 0 possibly blocking, 2 required, 2 nice to have. Both fixture fixes are correct. With the waive gone, every pre-merge stage that lists unittest/_torch/pyexecutor ran the whole directory in L0 #69312 with 0 failures: CPU x86 and CPU ARM (4515 cases each, test_gen_preemption 51/51 and test_overlap_admission_lifetime 2/2), DGX_H100 and B300 (2085 cases each). The two required items concern the PR description and two other open PRs, so they are listed here; the nice-to-have points are inline.

• [Required] The 14 failures this PR fixes are also tracked under two other bugs, each with an open auto-waive draft. #22002 (https://nvbugs/7075057) adds 12 full:CPU/unittest/_torch/pyexecutor/test_gen_preemption.py::... waives; its failure signature is no attribute _cancelled_disagg_model_request_ids. #22005 (https://nvbugs/7075738) adds 2 full:CPU/unittest/_torch/pyexecutor/test_overlap_admission_lifetime.py::test_adp_replacements_acquire_slots_before_retiring_requests_release_them[...] waives; its signature is ExecutorRequest.__init__() got an unexpected keyword argument 'input_token_ids'. These are exactly the cases this PR repairs. Both drafts say their lines come out only when their own bug is closed. If either draft is merged after this PR, the repaired tests are skipped on CPU again and both bugs stay open. Please list nvbugs/7075057 and nvbugs/7075738 in the description as fixed by this PR, and get #22002 and #22005 closed.
• [Required] The CodeRabbit QA section of the description says neither modified test file appears in a test-db list, and it gives the coverage verdict "needs follow-up". Both files are cpu_only and are collected by the directory entry unittest/_torch/pyexecutor at tests/integration/test_lists/test-db/l0_cpu.yml:109; they passed on CPU x86 and ARM in L0 #69312. The PR template asks you to make sure a CodeRabbit summary makes sense (.github/pull_request_template.md:46). Please correct or drop that paragraph so nobody adds duplicate per-file entries.

[Nice to have] This fixture breaks whenever _schedule starts calling another self.<helper>(), which is how this bug happened: _schedule now calls self._cancelled_disagg_model_request_ids() (py_executor.py:8927). Tests that build the fake with object.__new__(PyExecutor) (test_py_executor.py:2389, test_queued_context_cancellation.py:63) survived the same change. Their helpers resolve through the class, and this helper reads canceled_req_ids with getattr. Consider executor = object.__new__(PyExecutor) plus the attributes the test needs, here and in _admission_executor in test_overlap_admission_lifetime.py. In the latter, drop _kv_connector_moves_kv=False (a read-only property that already returns False without a connector) and keep canceled_req_ids=[].

[sunnyqgg]

[Nice to have] RequestQueueItem.__post_init__ already adapts a native Request (executor_request_queue.py:63-66), and _enqueue_impl relies on that (executor_request_queue.py:258). Passing Request(input_token_ids=[1, 2], max_tokens=1) directly runs that production normalization and lets you drop the ExecutorRequest import. It also keeps the test independent of the envelope's construction API, which is the coupling that broke it here.
