From 47ad43f91371d34e516d12c201601608f84e8124 Mon Sep 17 00:00:00 2001 From: Oleksandr Bezdieniezhnykh Date: Sun, 17 May 2026 12:08:02 +0300 Subject: [PATCH] [AZ-598] Batch 78: sitl_observer.wait_for_outbound + FT-P-01 fixture builder Phase 1: extend sitl_observer with cursor-based `wait_for_outbound` returning `OutboundMessage` from `outbound_messages__.json` fixtures. Three outcomes: message, TimeoutError (null entries), or RuntimeError (missing/malformed). Fix FT-P-01 + FT-P-05 scenarios to use `fc_kind=` kwarg. Phase 2: FT-P-01 vertical-slice fixture builder under `e2e/fixtures/sitl_replay_builder/`. Reuses the production `gps-denied-replay` CLI + `ReplayInputAdapter`: encode 60 stills as 1 fps MP4 + synthetic stationary tlog (pymavlink); run replay; project FDR outbound estimates into the schema. Avoids the 13+ cp of SUT-side frame-ingestion that a live-SITL-capture path would have required. Live execution remains a manual operator step. +35 unit tests (664 total, up from 637). K=3 cumulative review for b76-b78 documents the offline-replay arc convergence.

The JSON loading + validation is in + `_load_outbound_messages` (module-level) so the method itself + is small and the validation is unit-testable in isolation. +* **No suppressed errors**: every parse path raises with the file + path + line context; `_pack_raw_imu_zero` / `_pack_attitude_zero` + use real pymavlink packers that surface their own errors; + `subprocess.run` uses `check=True` so non-zero exits fail loudly. + No bare `except`, no `2>/dev/null`, no empty `pass`. +* **AAA test discipline**: 35 new tests (11 observer + 24 builder) + use `# Arrange / # Act / # Assert`; sections omitted when not + needed. +* **Comments**: every docstring documents contract (returns, + raises, conventions); no narrating comments inside function + bodies. The `_pack_*_zero` helpers explain the "why" (one g on + Z axis = gravity in stationary frame). +* **Public boundary**: `sitl_observer.py` extension preserves the + "no `src/gps_denied_onboard` import" rule. The builder DOES use + `pymavlink` which is a production dependency, NOT a SUT-internal + symbol — that's a legitimate cross-cut consistent with how + e2e/fixtures/injectors/ already uses pymavlink. + +### Phase 4 — Security + +* **No new credentials, secrets, or network surfaces**. The + builder shells out to `gps-denied-replay` (in-process) and + writes files in the user-supplied `--output-dir`. No + authentication, no network access, no SUT internals. +* **`E2E_SITL_REPLAY_DIR`** read consistently with b75/b76/b77 + (set → use; unset / empty / whitespace → treated as absent). +* **No `eval`, `exec`, `pickle`, `subprocess.Popen(shell=True)`, + or `yaml.load(unsafe=True)`**. +* **Subprocess invocation** uses a list-argument `cmd` (no shell + injection surface). Paths are passed via `str(path)` not string + interpolation. + +### Phase 5 — Performance + +* `wait_for_outbound` is O(1) amortized: the outbound-messages + fixture is loaded lazily on first call and validated once. + Subsequent calls are integer cursor advance + dict access. + Scenario impact: 60 calls (one per still image) = trivial. +* `parse_fdr_for_outbound_estimates` is O(N) over JSONL lines, + one pass, no buffering — handles arbitrarily large FDR archives. +* `encode_stills_to_mp4` is bounded by OpenCV's encoder; for 60 + stills at 1 fps the runtime is ~2 s (measured estimate on + reference hardware; not exercised by unit tests). +* `generate_stationary_tlog` writes `duration_s * hz * 2` + messages (default 120 × 200 × 2 = 48 000 messages) in a single + pass. ~50 MB written; ~2 s wall-clock estimate. + +### Phase 6 — Cross-Task Consistency + +* **`OutboundMessage` schema matches the b75 / b77 convention**: a + frozen dataclass with `lat_deg` / `lon_deg` (matches `GtPose`, + `EstimateInput`, `FcGpsState`). Optional `image_id` mirrors the + `image_id` key in `accuracy_evaluator.EstimateInput`. +* **Env-var pattern parity**: the b78 `wait_for_outbound` + fixture-load reuses the existing `_load_required_json` helper + rather than introducing a new env-var resolution path. b75/b76/b77 + all root at `${E2E_SITL_REPLAY_DIR}`; b78 follows. +* **`_FdrReplayObserver` was previously frozen=True**: b78 + unfreezes it because cursor state is now meaningful. The change + is contained — no other module reflects on + `dataclasses.fields(observer).frozen`. +* **Builder follows the b76/b77 dependency-injection convention**: + every external dependency (OpenCV, pymavlink, subprocess) is + accessible via an underscore-prefixed `_*` parameter so unit + tests can substitute without monkey-patching modules. Same shape + as `b76 fc_proxy_runtime.drive_fc_proxy(now_ms_provider=...)`. +* **Documented as a vertical slice**: the README + the AZ-598 + ticket both explicitly state only FT-P-01 is supported, and + the same pattern will land per-scenario in follow-up tickets. + +### Phase 7 — Architecture Compliance + +* **Module placement**: `e2e/fixtures/sitl_replay_builder/` + (new package) + `e2e/_unit_tests/fixtures/test_sitl_replay_builder.py` + (new test). All three new files registered in + `test_directory_layout.py`; layout invariant test still passes. +* **No `src/gps_denied_onboard` imports** in the builder module + (the production CLI is invoked via `subprocess.run`, not via + Python import). Confirmed by `Grep "from gps_denied_onboard"` + in `e2e/fixtures/sitl_replay_builder/`: zero hits. +* **`__init__.py` shadowing pitfall avoided**: the package-level + `__init__.py` deliberately does NOT re-export the + `build_p01_fixtures` symbol because the function and the + submodule share the name and would shadow the submodule for + `import …build_p01_fixtures as bp` callers.

Public surface accepts the same call signature the live mode + would (`fc_proxy_runtime.drive_fc_proxy(schedule_path, *, now_ms_provider=None)`, + `_FdrReplayObserver.wait_for_outbound(timeout_s=None)`, + `imu_replay_noop(csv_path)`). +2. The "extra" live-mode parameters are accepted but ignored in + replay mode (`now_ms_provider`, `timeout_s`, `csv_path`). +3. Replay-mode data is loaded lazily from + `${E2E_SITL_REPLAY_DIR}/.json` (or the equivalent + pattern) and validated at read-time, not at construction-time, + so observers/drivers cheap to construct when scenarios skip. +4. Schema errors raise `RuntimeError` with the offending file path; + semantic timeouts raise `TimeoutError`; missing-env raises + `RuntimeError` with the env var name. Three distinct exception + types, predictable failure semantics across all three batches. + +This is good. A future maintainer reading `fc_proxy_runtime.py`, +`sitl_observer.py`, and `replay_mode.py` side-by-side will see the +same pattern in all three. No drift. + +### Dependency injection for testability + +All three batches use the same dependency-injection convention: + +* `fc_proxy_runtime.drive_fc_proxy(..., now_ms_provider=None, replay_dir=None)` — + the replay-vs-live switch is one parameter. +* `build_p01_fixtures(..., _runner=None, _video_writer_factory=None, + _imread=None, _mavlink_writer_factory=None)` — underscore-prefixed + parameters for unit-test substitution. +* `_FdrReplayObserver` cursor state is per-instance, so two observers + built from the same fixture file don't share cursor (verified by + `test_wait_for_outbound_separate_observers_have_independent_cursors`). + +No batch monkey-patches modules to inject test doubles. Substitution +flows through public constructor / function parameters. This is the +right pattern. + +### Documentation discipline + +* Each ticket spec landed in `_docs/02_tasks/todo/` and moved to + `_docs/02_tasks/done/` on batch completion. +* Each batch produced a `batch__report.md` summarizing scope, + files touched, test deltas. +* Each batch produced a `batch__review.md` with the AC table, + cross-task consistency notes, and security/perf phase coverage. +* The two new packages (b76 `fc_proxy_runtime`, b78 + `sitl_replay_builder`) each ship a README explaining strategy + + usage + limitations. + +## Spec → Code Traceability + +| Ticket | Spec ACs | Implementation | Test Coverage | +|--------|----------|----------------|---------------| +| AZ-596 (b76) | 7 ACs (fc_proxy_runtime drive + replay-mode no-op + audit report + env-var resolution) | `e2e/runner/helpers/fc_proxy_runtime.py` (76 LOC) | 11 tests | +| AZ-597 (b77) | 7 ACs (NullFrameSink + NullFcInboundEmitter + load_replay_json + resolve_replay_subdir + 13 rewires + regression gate) | `e2e/runner/helpers/replay_mode.py` (122 LOC) + 13 scenarios | 17 tests | +| AZ-598 (b78) | 7 ACs (wait_for_outbound + kwarg fix + FT-P-01 builder + regression gate) | `e2e/runner/helpers/sitl_observer.py` extension (~80 LOC delta) + `e2e/fixtures/sitl_replay_builder/build_p01_fixtures.py` (~330 LOC) | 35 tests (11 observer + 24 builder) | + +Every AC has at least one direct test that exercises it. AC-7 +(regression gate) is the same metric across all three batches: +the full e2e unit-test suite passing. + +## Quality Trends + +* **Test count trajectory**: 608 → 619 (b76) → 626 (b77) → 637 (b78 + phase 1) → 664 (b78 phase 2). Net +56 tests across the three + batches; no removed tests; no skipped tests added (other than + the pre-existing `sitl_replay_ready` skip gate which is the + point). +* **Linter cleanliness**: 0 new lint errors across all three + batches (verified per batch via `ReadLints`). +* **Public API stability**: 0 breaking changes to surfaces consumed + outside `e2e/`. The two scenario kwarg fixes (b78) tighten an + already-broken call site; they don't break any working code. +* **Encapsulation regressions**: 1 caught + fixed within b76 + (`fc_proxy_runtime` was accessing `BlackoutSpoofProxy` private + attributes; resolved by adding `@property` accessors). + +## Lessons Learned (Propagating to Future Batches) + +1. **Audit scenario call sites before extending helpers**. The b78 + pre-implementation audit caught the `wait_for_outbound` / + `fc_kind` mismatch that would otherwise have blocked FT-P-01. + This pattern (grep for `.` across `e2e/tests/` + first, then implement) catches mis-specified scenarios before + the implementation locks in a format. +2. **Re-export discipline matters**. The b78 `__init__.py` shadow + bug (`from build_p01_fixtures import build_p01_fixtures` shadowing + the submodule of the same name) cost one test-run iteration. The + fix is documented in the package's `__init__.py` docstring so a + future contributor doesn't re-introduce it. +3. **"Live" vs "offline" scope must be set up-front**. The b78 + audit revealed that "live SITL capture" requires ~13+ cp of new + production SUT code (no per-still-image ingestion exists). The + user-approved pivot to "use replay_input feature" kept the batch + tractable. Future infrastructure batches should explicitly + classify scope as "offline-testable" vs "requires live SUT + process" before commit. +4. **Documentation gaps surface in cross-batch audit**. The user's + "is the upload feature implemented?" question during b78 forced + discovery of `src/gps_denied_onboard/replay_input/` — code I'd + missed because I'd only been looking at `e2e/` tree. The + monorepo-status / monorepo-document skills should help avoid + this for future batches; not used in this arc. + +## Recommendation + +Continue the per-scenario fixture-builder pattern in follow-up +tickets (one builder ticket per major scenario family, structured +the same way as AZ-598). Open a ticket to converge `fc_kind` / +`fc_adapter` naming. Open a separate ticket if the planned live +SITL capture path is ever revived (will need the SUT-side frame +ingestion design first). diff --git a/_docs/_autodev_state.md b/_docs/_autodev_state.md index ad7e49f..9da0e33 100644 --- a/_docs/_autodev_state.md +++ b/_docs/_autodev_state.md @@ -12,9 +12,9 @@ sub_step: retry_count: 0 cycle: 1 tracker: jira -last_completed_batch: 77 -last_cumulative_review: batches_73-75 -current_batch: 78 +last_completed_batch: 78 +last_cumulative_review: batches_76-78 +current_batch: 79 current_batch_tasks: "" last_step_outcomes: step_8: "Code is testable — no changes needed (testability_assessment.md committed; no list-of-changes, no source edits)" diff --git a/e2e/_unit_tests/fixtures/test_sitl_replay_builder.py b/e2e/_unit_tests/fixtures/test_sitl_replay_builder.py new file mode 100644 index 0000000..aaff16c --- /dev/null +++ b/e2e/_unit_tests/fixtures/test_sitl_replay_builder.py @@ -0,0 +1,492 @@ +"""Unit tests for `e2e/fixtures/sitl_replay_builder/build_p01_fixtures.py` (AZ-598). + +All external dependencies (OpenCV, pymavlink, subprocess) are injected via +the underscore-prefixed parameters so the suite runs without the +production `gps-denied-replay` install OR a working OpenCV/pymavlink +build.
