Política de colas a largo plazo: ¿Redis desde el inicio o in-memory ahora y migrar luego? (Usuario eligió: in-memory ahora) + +## Plan: Importadores y gestión de ROMs (Fase 4) + +Implementar servicios para escanear directorios de ROMs, detectar formatos (ZIP/7z/CHD), calcular checksums (CRC32/MD5/SHA1), verificar contra DATs (No-Intro/Redump) y persistir `RomFile` en la BD. El escaneo se lanzará desde el frontend, correrá como job en background y la ruta a las ROMs será una configuración del sistema (no se envía en cada request). Se añadirá la variable `IMPORT_CONCURRENCY` con cálculo por defecto. + +**Phases 4** + +1. **Phase 4.1: Tests y fixtures (TDD)** + - **Objective:** Escribir tests y fixtures que guiarán la implementación; los tests deben fallar inicialmente. + - **Files a crear:** + - `backend/tests/fixtures/simple-rom.bin` — fixture ROM sintética + - `backend/tests/fixtures/nested/nested-rom.bin` — fixture en subdirectorio + - `backend/tests/fixtures/dats/sample-no-intro.dat.xml` — DAT XML mínimo + - `backend/tests/services/fsScanner.spec.ts` + - `backend/tests/services/checksumService.spec.ts` + - `backend/tests/services/datVerifier.spec.ts` (marcar integración para binarios cuando aplique) + - `backend/tests/routes/import.spec.ts` + - **Criterio de aceptación:** Los tests existen y fallan por falta de implementación (TDD). + +2. **Phase 4.2: Core — Scanner y checksums** + - **Objective:** Implementar `fsScanner` y `checksumService` con streaming y control de concurrencia. + - **Files a crear:** + - `backend/src/services/fsScanner.ts` + - `backend/src/services/checksumService.ts` + - `backend/src/lib/fileTypeDetector.ts` + - **Criterio de aceptación:** Tests unitarios de Phase 4.1 pasan para los casos no relacionados con archives/CHD. + +3. **Phase 4.3: Archives y DAT verification** + - **Objective:** Implementar `archiveReader` (ZIP, 7z opcional) y `datVerifier`. + - **Files a crear:** + - `backend/src/services/archiveReader.ts` + - `backend/src/services/datVerifier.ts` + - **Notas:** CHD será soportado opcionalmente mediante `chdman` (si está instalado en el sistema); en la MVP se tratará CHD como blob para checksums si `chdman` no está presente. + +4. **Phase 4.4: API, job en background y E2E** + - **Objective:** Añadir endpoint `POST /api/import/scan` (sin recibir path; usa la ruta preconfigurada), job runner en background, endpoints `GET /api/import/status/:taskId` y `GET /api/import/result/:taskId`, y pruebas E2E que verifiquen persistencia en Prisma. + - **Files a crear:** + - `backend/src/routes/import.ts` + - `backend/src/controllers/importController.ts` + - `backend/src/plugins/importJobs.ts` (cola en proceso; migrable a Redis/BullMQ) + - **Criterio de aceptación:** E2E de import completo pasa en CI (con binarios instalados según sea necesario). + +**Decisiones tomadas** + +- `chdman` soporte: opcional. Si está instalado, lo usaremos; si no, se calcula checksum y se trata como blob. +- Endpoint `POST /api/import/scan`: no recibe `path`; la ruta a las ROMs se configura en el sistema (env var `ROMS_PATH`). +- El job se ejecuta en background; el frontend lanza el job a petición del usuario (botón "Scan"). +- Añadir `IMPORT_CONCURRENCY` (env var). Valor por defecto: `min(8, max(1, os.cpus().length - 1))` si no se configura. +- Tests que dependen de binarios (7z/chdman): se incluirán como tests de integración y se habilitarán en CI (instalación de binarios en workflow). + +**Open Questions (resueltas por el usuario):** + +1. Soporte `chdman` opcional — Aprobado. +2. No enviar `path` en payload; usar ruta preconfigurada — Aprobado (`ROMS_PATH`). +3. Job en background — Aprobado. +4. `IMPORT_CONCURRENCY` variable y fórmula por defecto — Aprobado. +5. Incluir tests dependientes de binarios y instalarlos en CI — Aprobado. + +**Siguientes pasos (Phase 4.1 - TDD):** + +1. Crear fixtures y tests unitarios marcados en Phase 4.1. +2. Ejecutar `yarn --cwd backend test` y observar tests fallidos. +3. Implementar servicios mínimos en Phase 4.2 para pasar tests básicos. + +--- + +Metadatos: + +- Autor: GitHub Copilot +- Fecha: 2026-02-08 diff --git a/plans/gestor-coleccion-plan-phase-5-complete.md b/plans/gestor-coleccion-plan-phase-5-complete.md new file mode 100644 index 0000000..711eae1 --- /dev/null +++ b/plans/gestor-coleccion-plan-phase-5-complete.md @@ -0,0 +1,31 @@ +## Phase 5 Complete: Job runner en memoria + +TL;DR: Se implementó un runner en memoria (`ImportRunner`) con control de concurrencia configurable, API de encolado (`enqueue`), estado (`getStatus`) y utilidades de parada (`stop`, `stopAndWait`).
