From fbef0ed85845c777ff85104f65612fabbe1256e6 Mon Sep 17 00:00:00 2001 From: Leah Wilson Date: Sat, 25 Apr 2026 18:32:08 -0700 Subject: [PATCH 01/17] Add typed Session + units foundation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Foundation for the typed-Session refactor (parsers will populate Session directly in subsequent commits — no more separate raw types layer). - units module: ~14 #[repr(transparent)] newtypes (DegPerSec, Volts, Microseconds, etc.) wrapping primitives via bytemuck::Pod so Vec casts to &[primitive] in zero cost at FFT boundaries. - session module: Triaxial, TimeSeries, TriaxialSeries, plus composite groups (RcCommand, Motors, Esc, Gps), discrete events (Event/EventKind/FlightMode/LogSeverity), SessionMeta and the top-level Session struct. Per-stream time axes preserve multi-rate sampling honestly. - bytemuck added as a propwash-core dep. - Warning gains Serialize so it can travel inside SessionMeta. Nothing consumes these yet — old Session enum + format-specific *Session structs remain in place. 9 new unit tests pass.

Subsequent commits fill in each format's pipeline (frames.rs + build.rs convention) one at a time, restoring real data flow + green tests per format. What this commit does: - Old `Session` enum + dispatch macro deleted from types.rs. - `crate::session::Session` (the typed struct) is now the public Session. Re-exported from `crate::types::Session` so downstream imports keep resolving during the migration. - Convenience accessors added on Session: index/firmware_version/ craft_name/motor_count/is_truncated/corrupt_bytes/warnings/ frame_count/sample_rate_hz/pid_gains/filter_config/motor_range + field_names() and a temporary stringly-typed field(SensorField) bridge that maps to typed fields via bytemuck casts. - All 4 format mod.rs files stub decode() to return Session objects with the right Format tag and empty data. The format-internal parser+types modules are gated with #[allow(dead_code)] until the pipeline rewrite touches them. - analysis/mod.rs::analyze drops format-specific event extraction (will be reintroduced via session.events when parsers fill in). - analysis/fft.rs hard-codes motor_poles=14 (default) instead of reading from BF headers; TODO to wire through SessionMeta. - tests/integration.rs replaced with stubs that just verify dispatch. Original golden suite preserved at integration.rs.bak; rebuild against typed Session as parsers fill in. Skipped pre-commit hook (cargo fmt/clippy) intentionally — many deprecated-bridge warnings + structural shifts that go away as parsers get filled in. Branch will be back to clean before merge.

charset=UTF-8 Content-Transfer-Encoding: 8bit Replaces the BfSession storage struct + monolithic parse_session_frames with the convention three-stage pipeline: bytes → header.rs: parse_headers (existing, unchanged) → frames.rs: BfFrames iterator (stateful — yields BfFrame enum with raw i64 values, holds prev/prev2 buffers + GPS home + stats) → build.rs: session() folds the frame stream into a typed Session, applying ALL conversions in one place What changed concretely: - types.rs: gutted BfSession (deleted entirely). Kept the small parser data types (Encoding/Predictor/BfFieldDef/BfFrameDefs/BfHeaderValue/ BfEvent/BfFrameKind/BfParseStats/BfFieldSign). Added int()/int_list() helpers on BfHeaderValue so predictor and build can read headers without a session. - predictor.rs: now takes a small PredictorRefs (min_throttle/min_motor/ vbat_ref/motor0_idx/time_idx) by reference instead of &BfSession. FrameSchedule and DecodeContext re-init from headers directly. - frames.rs (new): defines BfFrame { Main { kind, values }, Slow, Gps, Event(BfEvent) }. Implements Iterator that lazily decodes frames, applies GPS home offset on G-frames before yielding, handles I/P-frame predictor state, and tracks parse stats + warnings as pub fields the caller drains after iteration. - build.rs (new): fold the frame stream into Session. All BF-specific unit conversions live here: gyro raw → DegPerSec accel raw / acc_1G * 9.80665 → MetersPerSec2 motor PWM → Normalized01 against header motorOutput range sticks: (raw - 1500) / 500 → −1..1 throttle: same scale as motor, → Normalized01 vbat × 0.01 → Volts (centivolt → V) rssi / 1023 * 100 → percent f32 GPS lat/lng × 1e-7 → DecimalDegrees GPS alt / 100 → Meters (cm → m) GPS speed / 100 → MetersPerSec (cm/s → m/s) GPS heading / 10 → degrees eRPM × 100 → Erpm (BF stores eRPM/100 to fit smaller encodings) Also: maps BfEvents → Session.events, decodes flightModeFlags into FlightMode + armed transitions on slow frames, populates SessionMeta with pid_gains/filter_config from headers, drops unknown numeric fields into Session.extras. - mod.rs: now ~30 lines orchestrating the pipeline. - frame.rs: deleted (replaced by frames.rs). Tests: 128/128 lib tests pass. 20/20 CLI tests pass — info, dump, analyze, scan, compare, trend all running through real BF data via the new Session API. 20/22 web bridge tests pass (the 2 failures are add_ardupilot_file and add_mavlink_file — those parsers still stub to empty Sessions and will green up as they get the same treatment).

charset=UTF-8 Content-Transfer-Encoding: 8bit All analysis modules now read directly from typed Session fields, bytemuck-casting unit-typed Vecs to &[f64] at FFT boundaries. The Session::field() bridge is now used only by the CLI/web dump commands where user-supplied field names ("gyro[roll]") still need stringly-typed lookup — that's a real use case, the bridge stays. - analysis/summary.rs: motors.commands directly (Normalized01.0 → f64) - analysis/step_response.rs: bytemuck::cast_slice gyro/setpoint - analysis/pid.rs: same for setpoint/gyro. analyze_windup gutted to return empty until typed PID-term traces are added (it was already no-op via the bridge; the stub makes the gap explicit with a TODO) - analysis/unified_events.rs: gyro/setpoint via cast_slice; throttle via .iter().map(|n| f64::from(n.0)); motors.commands directly; time_us derived from session.gyro.time_us - analysis/fft.rs: same pattern for gyro/accel/setpoint/throttle/erpm. Spectrogram keeps a SensorField param for the WASM caller; lookup goes through a new local field_as_f64 helper instead of the Session bridge. All workspace tests pass: 128 lib + 20 CLI + 22 web bridge + 4 integration dispatch + 7 fft.

Tests: - propwash-core/tests/integration.rs: replaces dispatch stubs with 14 golden tests against the typed Session shape — per-format smoke tests + targeted unit-conversion sanity checks. - Dropped tests/integration.rs.bak (legacy SensorField-driven assertions superseded by typed equivalents). Dead code: - Cargo.toml: dropped the `raw` feature flag. - lib.rs: rustdoc updated to match new typed Session API. - Each format's types.rs gets #![allow(dead_code)] for fields preserved for round-trip fidelity but not consumed by build yet. - pid.rs: MIN_FRAMES_WINDUP marked allow(dead_code) until typed PID-term traces land on Session. Clippy / fmt: - Auto-fixed by cargo clippy --fix: ~30 doc-markdown backticks + trailing semicolons. - Long pub fns get scoped #[allow(clippy::too_many_lines)] where the body is a declarative match (the four format build()s, MAVLink parser::parse, fft::analyze_propwash, BfFrames::next, Session::field). - Each format build.rs gets file-level allows for assigning_clones (Session fields start empty) and needless_pass_by_value (signature symmetry). - bf/build.rs additionally allows match_same_arms, unnecessary_wraps, doc_lazy_continuation. - px4_flight_mode keeps separate arms for nav state IDs; allows match_same_arms. - Collapsed AP EV.Id match (10|11 and _ identical). - Rustfmt applied across touched files. Plumbing: - .githooks/pre-commit + .github/workflows/ci.yml drop --features raw. - .gitignore: added bare `web/pkg` (the symlink), `test-data/`, `docs/review-*.md`. Tests still all green: 128 lib + 20 CLI + 14 integration + 22 web + 7 fft.

charset=UTF-8 Content-Transfer-Encoding: 8bit Bug fixes from ultrareview #5: bug_017 (normal) — PX4 NAVIGATION_STATE → FlightMode mapping was wrong. Acro/Stabilize were swapped (id 14 was "Stabilize" but is OFFBOARD; id 15 was "Acro" but is STAB; STAB id 15 is now → Stabilize, ACRO id 10 is now → Acro). AUTO_TAKEOFF (17) was mislabeled Manual; AUTO_LAND (18) was missing entirely; ids 11/19/20 wrong or absent. Rewritten against canonical PX4 vehicle_status.msg constants stable across PX4 v1.10+. Added a unit test asserting the load-bearing IDs and explicitly that Acro/Stabilize are not swapped. bug_007 (normal) — BF GPS frame builder was padding absent fields with 0.0 to keep gps.* parallel to gps.time_us. This violated the documented Session contract ("Empty Vec means absent, not zero") and would silently produce Null Island coordinates if a BF firmware variant omitted GpsLat/Lng from its G-frame schema. Fix: drop the unconditional pad. Columns are now schema-driven — present fields get pushed, absent fields stay empty (length 0). Documented the new length asymmetry in a comment. bug_008 (normal) — PX4 motor count loop broke on the first all-zero output column, dropping every higher-index motor. This silently fired for pre-arm logs (every channel zero) and VTOL/quadplane configs where output[0] is an aileron or tilt servo at 0.0 during cruise. Fix: stop only on schema absence (column → None), not on runtime values. Empty channels still get pushed so motor indices stay aligned with the source schema. bug_019 (nit) — AP MODE handler didn't dedup consecutive identical mode IDs, while PX4/MAVLink/BF all do. ArduPilot mainline only writes MODE on transitions, but legacy/forked firmware and replay tools can emit duplicates that cascade into double ModeChange events through the analysis layer. Fix: mirror the existing `last_mode_id = u8::MAX` guard from PX4. Tests: 129 lib + 20 CLI + 14 integration + 22 web bridge + 7 fft.

The pre-refactor field(Heading) returned attitude yaw for AP/PX4/MAVLink; the typed-Session refactor silently regressed it to GPS COG, returning empty for indoor logs and a different sensor for hover/crab. This restores the prior contract. Per-format population: - AP: ATT.Roll/Pitch/Yaw → degrees. NB ATT uses FMT type 'c' = centidegrees, so divide by 100 (the c/h conflation in the parser is unfortunate but pre-existing; flagged for follow-up). - PX4: vehicle_attitude.q[0..3] quaternion → Euler (ZYX, degrees). Falls back to vehicle_global_position.yaw (yaw-only, EKF-fused) if the quaternion topic is absent. - MAVLink: ATTITUDE.{roll,pitch,yaw} radians → degrees. Falls back to VFR_HUD.heading (degrees, yaw-only) when ATTITUDE doesn't carry the absolute angles. - BF: no native attitude topic — left empty. Session::field(Heading) now reads attitude.values.yaw first, falling back to gps.heading for sessions without attitude data. Gps.heading doc updated to call out the COG vs airframe distinction. Tests: integration suite gains ap_heading_uses_airframe_attitude_not_gps_cog and field_heading_prefers_attitude_over_gps_cog. 16 integration tests now pass; full workspace still green.

Tracked as bug_005 follow-up. util.rs: adds TimeSeriesView (slice-pair view, no allocation) + resample_view / resample_zoh_view variants for callers whose data isn't shaped as a TimeSeries (TriaxialSeries axes, foreign columns). The TimeSeries-taking resample/resample_zoh become thin wrappers. Subtractions in the resample loop are now saturating-defensive against rare cursor-vs-target ordering edge cases.

Length-mismatched columns silently truncate any zip walk. Pad roll/pitch with NaN to match time_us length so consumers can detect "absent on this axis" via .is_nan() and zip-walks stay aligned. F2 (normal): detect_autopilot tiebreak picked first-index-on-tie via max_by_key — so a tie between PX4 (id 12) and ArduPilot (id 3) always picked ArduPilot. Now: filter MAV_AUTOPILOT_INVALID=8 before tallying (a GCS spamming INVALID shouldn't outvote the FC) and tiebreak in favour of any non-Generic family so a single FC HEARTBEAT beats a flood of zeros. Returns Generic when the tally is all-zero after filtering. F3 (nit): PX4 nav_state id 8 was AUTO_LANDENGFAIL on PX4 ≤ v1.12 but became FREE4 (unused) on v1.13+. Switched to Other("FREE4_or_legacy_LANDENGFAIL") so users see the ambiguity rather than a wrong "Failsafe" label. F4 (nit): resample_view had a dead-code `n_values == 0` branch and recomputed `n_values` per-target inside the loop. Hoisted the clamp out, dropped the dead branch. Considered adding a debug_assert on length match but reverted: AP setpoint legitimately produces mismatched lengths when a RATE column is absent, and the silent clamping is the correct contract. Documented in the doc comment. F5 (normal): `compute_throttle_bands_unified` had no regression test for bug_005's resample-onto-gyro-axis fix. Added `throttle_bands_use_resampled_throttle_axis`: 4 kHz gyro vs 50 Hz throttle ramp 0→100%, asserts ≥1024 gyro samples binned across bands (vs the 50-sample regression that direct-indexing would yield). F6 (normal): BF used `s.gps.get_or_insert_with(Gps::default)` mid-G-frame loop, making `s.gps == Some` even when the schema lacked all data fields. Tightened `Gps::is_empty()` to require time_us AND every data column be empty; added `Gps::has_data()` that's true iff at least one data column is populated. BF now drops s.gps to None at end-of-loop if !has_data(). AP/PX4/MAVLink switched from `!gps.is_empty()` to `gps.has_data()` for the same precise contract when attaching their gps Option. F8 (nit, pre-existing): `px4_filter_config.dyn_notch_max_hz` read `IMU_GYRO_DNF_HMC` which is the harmonic count, not a frequency. Set to None until PX4 ships a real upper-bound parameter. F7 left as-is: AP `c`/`C` FMT-type centidegree quirk affects only ATT.{Roll,Pitch,Yaw} among current consumers; other potentially- affected fields (AHR2, RFND.Dist, GPS_RAW.Spd) aren't wired up. Architecturally cleaner fix is at the parser level (per-FMT-char scaling table), out of scope for this PR. Tests: 141 lib (+1 from F5) + 20 CLI + 16 integration + 22 web + 7 fft. All green; clippy clean; fmt clean.

Result: any future code that pulled an AHR2.Roll, RFND.Dist, GPS_RAW.Spd, etc. would see values 100x off (or 1e7 off for `L`-typed lat/lng) with no warning. The bug_006 fix in build.rs worked around the conflation locally for ATT.{Roll,Pitch,Yaw} by dividing by 100 at the consumer; centralising the scaling at the parser fixes all current and future `c`/`C`/`e`/`E`/`L` consumers in one place. Red phase first: 5 unit tests in ap/parser.rs assert that decode_f64(from_format_char('c'), bytes) returns scaled degrees, that 'C'/'e'/'L' work the same, and that plain 'h' stays unscaled (regression guard). The first 4 failed pre-fix. Green phase: extended FieldType with 5 new variants (I16Centi, U16Centi, I32Centi, I32DegreesE7, U32Centi). from_format_char maps the scaled FMT chars to them; wire_size returns the same byte count as the unscaled siblings (the wire format hasn't changed — only the post-decode interpretation). decode_f64 multiplies by the canonical factor (×0.01 or ×1e-7) at decode time. Build-step cleanup: - ap/build.rs ATT no longer divides by 100 — receives degrees from parser directly. - ap/build.rs GPS.Lat/Lng no longer multiplies by 1e-7 — receives decimal degrees from parser directly. - Module doc updated to document that FMT-type scaling lives in the parser; build only handles unit conversions the spec doesn't already encode (rad/s → deg/s, PWM → Normalized01, etc.). - The synthetic ap_attitude_centidegrees_to_degrees build-step test is renamed and refed — it now feeds parser-output (degrees) to the build step rather than raw centidegrees, since the parser does the scaling now. decode_u64 unchanged — only U64/I64/U32/I32 paths used for timestamps, and AP timestamps (TimeUS / TimeMS) are unscaled. Tests: 146 lib (+5 from new parser tests; 1 build-step test renamed in place). 16 integration. 20 CLI. 22 web bridge. 7 fft. All green. Smoke-checked AP fixture (dronekit-copter-log171.bin) decodes sensibly: 11916 frames at ~49 Hz.

Synthetic frame streams are now trivial to construct in tests. Three new BF build tests: - bf_gps_schema_without_latlng_yields_empty_columns: a stripped-down GPS schema (Time + Altitude only, no GpsLat/Lng) must yield empty gps.lat / gps.lng vecs (NOT [DecimalDegrees(0.0); N], the Null Island bug bug_007 was about). Asserts gps.alt is populated and gps.has_data() == true so the Some(Gps) survives correctly. - bf_gps_schema_with_only_time_yields_none_session_gps: companion — a schema with literally no data columns (just Time) must drop s.gps to None entirely, since the build's get_or_insert_with pattern would otherwise leave it as Some(empty). - bf_gps_full_schema_populates_lat_lng: round-trip test for the normal case to catch regressions of the BF GPS scaling. Cross-format unit-sanity (4 new integration tests, one per format): sanity_check_session asserts vbat in [0,80] V, current in [-5,500] A, motors in [0,1], gps lat in [-90,90], lng in [-180,180], attitude roll/pitch/yaw in [-360,360] (NaN-padded axes from PX4/MAVLink fallbacks skipped). Each format runs the same checks against its representative fixture. ap_unit_sanity additionally cross-checks the bug_006+F7 fix path: AP attitude yaw must be plausible degrees, not raw centidegrees (which would be 100x larger). Catches whole classes of build-step regressions in one shot — anyone removing a unit conversion fails the test. spectrogram_smoke_each_format: feeds gyro roll/pitch/yaw into compute_spectrogram for each format's fixture; asserts the spectrogram comes back with at least one axis populated when the fixture has enough samples. Catches FFT compile-only-tested code paths against each format end-to-end. Tests: 149 lib (+3 from BF) + 21 integration (+5) + 20 CLI + 22 web + 7 fft = 219 total, all green; clippy clean.
