From 4e58d3dcb0bda3a6252bc4bbf3343b507533bed1 Mon Sep 17 00:00:00 2001 From: Cursor Agent Date: Tue, 2 Jun 2026 02:54:59 +0000 Subject: [PATCH] PR-N4: remove SDK conftest stub + finalize no-doubles cleanup MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Final installment of the no-test-doubles cleanup. Closes the sequence PR-N1 \u2192 N2 \u2192 N3 \u2192 N4. After PR-N4 lands, NO test doubles implementing the verifier / engine / tokenizer protocols remain in the Linux test tree. What was deleted ---------------- tests/sdk/python/conftest.py -203 lines. Contained _start_runtime / _stop_runtime helpers that spun up an in-process gRPC server with a FakeVerifier (later replaced by _MinimalVerifierStub in PR-N1's preview cleanup) on a background thread. The runtime_address + runtime_address_no_inspector fixtures are gone with it. tests/sdk/python/test_client.py -157 lines, 13 tests. Exercised Client + Session lifecycle against the FakeVerifier-backed runtime. tests/sdk/python/test_session.py -502 lines, 33 tests. Exercised Session.append + .generate + .info + .close end-to-end against the FakeVerifier-backed runtime. What was added -------------- tests/integration/test_sdk_real.py +137 lines, 11 tests SDK Client + Session integration tests against a real Qwen3-0.6B-backed gRPC runtime: - Client: create_session round-trip, eos_token_ids round- trip, idempotent close, address property - Session: append + generate yield tokens + metadata, info reflects history, close returns final length, close is locally idempotent - End-to-end error mapping: SessionNotFoundError on unknown id, InvalidArgumentError on max_tokens=0, SessionClosedError on append-after-close tests/integration/conftest.py +180 lines - pytest_collection_modifyitems hook (auto-marks everything under tests/integration/ with @pytest.mark.integration) - real_speculative_engine fixture (session-scoped, Qwen3-0.6B) - real_grpc_runtime_address fixture (session-scoped, in-process gRPC server backed by real Qwen3-0.6B verifier on a background thread; yields the host:port the SDK can connect to) tests/integration/__init__.py +0 lines (placeholder) scripts/review_pr_n4_on_mac.sh +93 lines Mac M4 reviewer aid running the full accumulated integration suite (PR-E1 INV-3 + PR-N1 coordinator/generator + PR-N2 scheduler + PR-N3 http_shim/engine/tokenizer/streaming + PR-N4 SDK). What stays on Linux ------------------- tests/sdk/python/test_errors.py (unchanged, 9 tests) Pure _wrap_grpc_error mapping with synthesized grpc.RpcError objects. Verifier-independent; transport-only error-class translation. Stays on Linux. CI workflow change ------------------ .github/workflows/ci.yaml: dropped kakeya.client and kakeya.session from the --include= filter. Linux gate now covers ONLY: inference_engine/server/{auth, config, errors, grpc_app, metrics, schemas, proto_gen} inference_engine/memory/* inference_engine/scheduler/{config, session, pooled_verifier} inference_engine/pipeline/* inference_engine/session/store sdks/python/kakeya/{__init__, errors} training/repr_align/* That's the verifier-independent boundary, frozen post PR-N4. Final state of the no-doubles cleanup ------------------------------------- PR-N1 (#53): retired FakeVerifier hierarchy (tests/inference_engine/session/test_coordinator.py, test_generator.py, test_grpc_app.py FakeVerifier-using sections). PR-N2 (#54): retired DeterministicEngine + DeterministicTokenizer (tests/inference_engine/scheduler/conftest.py + test_scheduler.py). PR-N3 (#55): retired the HTTP shim cluster (server/conftest.py + 6 test files + their subtypes). PR-N4 (this): retired the SDK conftest stub. The integration suite at tests/integration/ now contains: test_inv3_session_determinism_gate.py (PR-E1) test_coordinator_real.py (PR-N1) test_generator_real.py (PR-N1) test_scheduler_real.py (PR-N2) test_http_shim_real.py (PR-N3) test_engine_real.py (PR-N3) test_tokenizer_real.py (PR-N3) test_streaming_real.py (PR-N3) test_sdk_real.py (PR-N4) Linux verification ------------------ PYTHONPATH=.:sdks/python coverage run -m pytest : 649 passed (was 695 on main; -46 net = removed 46 SDK runtime tests, kept 9 SDK error-mapping tests). 100% coverage on 999 stmts (was 1660 on main; -661 net stmts is all verifier-dependent modules now integration-only). Mac M4 evidence (REQUIRED for merge) ------------------------------------ Per ADR 0008 \u00a79: this PR's runtime correctness lives in the integration suite. Reviewer runs: bash scripts/review_pr_n4_on_mac.sh git add results/platform-tests/pr-n4-mac-* git commit -m 'Mac M4 review evidence for PR-N4' git push Stack ----- PR-N4 is branched off main, independent of PR-N1 (#53) / PR-N2 (#54) / PR-N3 (#55) at the file level. Conftests in tests/integration/ added by N1/N2/N3/N4 are file-disjoint from each other (each adds one fixture) but the file IS shared, so post-merge the four contributors' fixture defs need to be reconciled. The recommended merge order: 1. PR-N1 (verifier doubles) — adds conftest with marker hook 2. PR-N2 (engine/tokenizer doubles) — adds real_speculative_engine 3. PR-N3 (HTTP shim doubles) — uses real_speculative_engine 4. PR-N4 (this, SDK doubles) — adds real_grpc_runtime_address If a different order lands first, the integration conftest needs a small merge to combine fixtures.
