- Add Dockerfile.fast which packages a pre-built binary instead of compiling inside the container.
- Add scripts/build-fast.ps1 (PowerShell) and scripts/build-fast.sh (Bash) to automate local cross-compilation (CGO_ENABLED=0 GOOS=linux) and Docker packaging.
- Set executable bit for build-fast.sh.
- Add initial versions of hardware bills of materials (BOM v1-v4), shopping lists, plan, and assembly guides.
- Add STL models for 3D-printing the 1/27 scale OpenRC F1 car parts.
- Add Blender 3D project files (.blend) and camera renders of the car design iterations.
- Add ESP32 client firmware source (client.ino) for handling video streaming and car controls.
- Ignore Blender backup files (*.blend1, *.blend2) and IDE directories.
- Implement UDPVideoService to stream MJPEG video frames from ESP32s via UDP and send control commands.
- Normalize race database schema:
- Remove redundant driver_ids array from races table (migration 011).
- Move per-driver outcomes (total_time_ms, best_lap_ms, position) to race_drivers table (migration 012).
- Add device_id column to lobby_drivers to link active physical devices (migration 013).
- Update WebSocket handler to pass lobbySvc, driversSvc, and videoSvc for driver identity tracking, syncing in-memory driver metadata, and forwarding WS controls to physical cars.
- Add CORS middleware to HTTP routes.
- Regenerate Swagger documentation.
This commit captures the full server code accumulated across
several development sessions. It includes the following layers,
applied in roughly this order during development:
1. Base infrastructure
- cmd/poc-server HTTP+WebSocket server, /health, /stats
- internal/transport wire types (Envelope + all message types)
- internal/catalog, internal/realtime, internal/stats
- internal/storage/postgres with migrations 001-004
- .env, .env.example, docker-compose, Dockerfile, scripts/
2. Swagger documentation
- go get github.com/swaggo/http-swagger
- swag init produces docs/docs.go
- /swagger/index.html UI, /swagger/doc.json spec
- annotations on health/stats/ws and catalog handlers
3. Races API
- internal/races/{store,service,keyset,types}.go
- migration 005_races.sql: finished_races, race_plans, race_queue
- GET /api/races with keyset pagination, status filter
- GET /api/races/upcoming
- POST /api/races/queue/join, GET, DELETE
- POST/GET /api/races/plans, DELETE /{id}
- lobby.RaceMeta simplification (no host_id/host_name)
4. Races seeder
- internal/races/seed with deterministic generator
- --seed-races / --reset CLI flags in main.go
- 30 finished + 5 live + 5 plans + 4 queue entries
5. Drivers and clans
- internal/drivers, internal/clans (CRUD, validation)
- migration 008_drivers_clans.sql
- /api/clans and /api/drivers endpoints
- 3-letter uppercase nickname/tag validation
- lobby.DriverMeta: Nickname, AvatarURL, ClanID, ClanTag
6. Podium
- internal/transport.RacePodiumEntry
- lobby.SetDriverProfile for in-memory metadata sync
- migration 007_podium.sql (podium JSONB column)
- seeder populates top-3 per finished race
7. Live races persistence
- migration 009_live_persistence.sql: live_races,
live_race_drivers, lobby_drivers
- internal/races/live_store.go: LiveStore with write-side
mirror for lobby.Service mutations
- Service.collectLive and Upcoming read from Postgres
- main.go RestoreFromDB rehydrates lobby on startup
8. Unify live + finished into one races table
- migration 010_unify_races.sql: rename finished_races to
races, expand status CHECK, merge live rows
- PgStore now hosts both write paths; LiveStore is a
thin facade implementing lobby.Persistence
- seeder resetAll drops only finished/cancelled rows and
race_plans / race_queue / lobby_drivers
Each layer is consistent on its own; cross-layer changes are
visible in the file history. A future refactor may split this
commit into the per-stage boundaries listed above.
