Arquitectura asincronica completa para correr 24/7 a bordo del buque.
vmssailor/runtime/server/tag_store.py
- TagStore in-memory con pub/sub asyncio.Queue
- register_tag/register_many con valores iniciales
- TagValue dataclass: value + quality + timestamp + raw_value
- subscribe()/unsubscribe() para fan-out
- stats() con breakdown por Quality
vmssailor/runtime/server/historian.py
- Historian DuckDB embebido (in-memory o archivo)
- Reader loop suscrito al tag_store + buffer + flush periodico (1s)
- query(tag_id, since, until, limit) para series temporales
- Soporta valores numericos y boolean separadamente
vmssailor/runtime/server/alarm_engine.py
- Suscriptor al tag_store que evalua AlarmConfig por update
- Operators: >, >=, <, <=, ==, !=
- Hysteresis correcta: aplica al SALIR de alarma, no a entrar
- Delay configurable (persistencia minima antes de disparar)
- Estados: ACTIVE -> ACK (con user) -> CLEARED
- ack(alarm_id, user) reconoce sin clear
vmssailor/runtime/server/drivers.py
- SimulatorDriver: produce valores sinteticos creibles por UnitSI
- Tick configurable (default 0.5s)
- Respeta range_normal_min/max del tag para mantenerse en rango
- Permite probar UI/API sin hardware ni Modbus real
vmssailor/runtime/server/runtime_app.py
- RuntimeApp dataclass ensambla todos los servicios
- build_runtime(project) construye listo para correr
- start()/stop() async lifecycle ordenado
vmssailor/runtime/server/api.py
- FastAPI app con lifespan que arranca/detiene el runtime
- GET /health, /project
- GET /tags, /tags/{id}, /tags/{id}/history
- GET /alarms, POST /alarms/{id}/ack
- WebSocket /ws/realtime con snapshot inicial + push + heartbeat
runtime_server_main.py
- Entry point con argparse: --vmsproj, --host, --port, --db
- Sin --vmsproj usa proyecto demo Sprint 0 (genera simulator vivo)
- Lanza con uvicorn
Tests (tests/runtime/, 16 nuevos, total 142/142):
- test_tag_store: register, update, subscribe, unsubscribe, stats
- test_historian: roundtrip query, stats
- test_alarm_engine: fire when below, hysteresis clears, ack
- test_api: health, project, tags listing, history, alarms via httpx.ASGITransport
Para correr el servidor en vivo:
uv run python runtime_server_main.py --verbose
Luego en otro shell:
curl http://127.0.0.1:8765/health
curl http://127.0.0.1:8765/tags | jq .
Dependencias agregadas:
- fastapi >=0.110
- uvicorn[standard] >=0.27
- websockets >=12.0
- duckdb >=0.10
- pymodbus >=3.5 (Sprint 5)
- python-can >=4.3 (Sprint 5)
- httpx >=0.27 (testing + cliente HTTP)
142/142 pytest verde, ruff clean.
