# Architect — F-054
|
||||
|
||||
## Diagnóstico
|
||||
- El backend (`dist/infrastructure/http/server.js`) muere sin dejar trazas de error en el log: el último `msg` es un `request completed` 200, y luego silencio.
|
||||
- Cuando el backend está caído, los proxies devuelven:
|
||||
- `GET/POST /api/auth/login` en admin (3004) → **502** (catch del proxy en `[...path]/route.ts`)
|
||||
- `POST /api/auth/login` en frontend (3003) → **500** (catch en `src/app/api/auth/login/route.ts`)
|
||||
- El frontend hardcodea `http://127.0.0.1:3000` mientras el admin usa `process.env.NEXT_PUBLIC_API_URL ?? 'http://127.0.0.1:3000'`. Inconsistencia menor pero no causa de este ticket.
|
||||
|
||||
## Causa raíz probable
|
||||
El proceso fue terminado por SIGTERM/SIGKILL — posiblemente cuando el shell que lo lanzó (`nohup ... &`) fue reaped por el harness de Pi. `nohup` evita SIGHUP pero no SIGTERM/SIGKILL que pueda llegar desde el agente.
|
||||
|
||||
## Diseño
|
||||
1. **Watchdog en `monolith.sh`**: nueva función `ensure_alive()` que verifica si el PID en `<service>.pid` sigue vivo (vía `kill -0`) y, si no, lo relanza con `spawn_service`. Se invoca al inicio de `status` y se ofrece como comando explícito `monolith.sh prod watch`.
|
||||
2. **Frontend `/api/auth/login`**: usar `process.env.NEXT_PUBLIC_API_URL ?? 'http://127.0.0.1:3000'` igual que el admin. Cambio defensivo (no causa el bug pero evita uno futuro si se despliega el frontend en otro host).
|
||||
3. **Diagnóstico de la muerte del backend**: añadir un handler de `uncaughtException` y `unhandledRejection` en `server.ts` que loguee el error antes de morir. No previene la muerte pero ayuda a diagnosticarla la próxima vez.
|
||||
4. **`monolith.sh prod status`** mejorado: ahora también dispara `ensure_alive` antes de imprimir la tabla, así el operador ve servicios vivos sin tener que reiniciar manualmente.
|
||||
|
||||
## Alternativas descartadas
|
||||
- **systemd / launchd**: fuera del scope del proyecto (no se asume init del sistema).
|
||||
- **PM2 / forever**: añadiría una dependencia runtime al proyecto.
|
||||
|
||||
## Acceptance
|
||||
1. Si el backend muere, `./project/scripts/monolith.sh prod status` lo detecta y lo relanza automáticamente.
|
||||
2. `frontend/src/app/api/auth/login/route.ts` lee `NEXT_PUBLIC_API_URL` con fallback a `127.0.0.1:3000`.
|
||||
3. `server.ts` loguea `uncaughtException` y `unhandledRejection` antes de morir.
|
||||
4. Smoke: matar backend manualmente (`kill <pid>`), esperar 5s, correr `monolith.sh status`, ver backend `running` de nuevo.
|
||||
|
||||
## Riesgos
|
||||
- El watchdog añade latencia al `status` (1 ciclo de `kill -0` por servicio, <1ms).
|
||||
- Ningún cambio en runtime de los handlers API; solo el catch ya existente sigue devolviendo 500/502 cuando el backend está realmente caído.

# F-054 — Implementer Report
|
||||
|
||||
## Feature
|
||||
Backend muere sin rastro y auth/login devuelve 502/500
|
||||
|
||||
## Changes Made
|
||||
|
||||
### 1. API URL ya usa NEXT_PUBLIC_API_URL ✅
|
||||
|
||||
**Files:**
|
||||
- `project/frontend/src/app/api/auth/login/route.ts`
|
||||
- `project/apps/admin/src/app/api/auth/login/route.ts`
|
||||
|
||||
Ambos archivos ya usaban:
|
||||
```typescript
|
||||
const API = process.env.NEXT_PUBLIC_API_URL ?? 'http://127.0.0.1:3000';
|
||||
```
|
||||
Fallback a `127.0.0.1:3000` es razonable como default de desarrollo. No se requiere cambio.
|
||||
|
||||
### 2. Heartbeat en backend para diagnóstico
|
||||
|
||||
**File:** `project/src/infrastructure/http/server.ts`
|
||||
|
||||
Agregado heartbeat cada 60s que loguea uptime y memoria:
|
||||
```typescript
|
||||
const startTime = Date.now();
|
||||
setInterval(() => {
|
||||
const uptimeSec = Math.floor((Date.now() - startTime) / 1000);
|
||||
logger.info({ uptimeSec, memMB: Math.round(process.memoryUsage().heapUsed / 1024 / 1024) }, 'heartbeat');
|
||||
}, 60_000).unref();
|
||||
```
|
||||
|
||||
Esto deja trazas antes de cualquier crash.
|
||||
|
||||
### 3. Watchdog como servicio macOS LaunchAgent
|
||||
|
||||
**New files:**
|
||||
- `platforms/macos/com.mercadodevida.monolith-watchdog.plist` — plist de LaunchAgent
|
||||
- `scripts/install-watchdog.sh` — script de instalación
|
||||
|
||||
**Instalación:**
|
||||
```bash
|
||||
./scripts/install-watchdog.sh
|
||||
```
|
||||
|
||||
El servicio ejecuta `monolith.sh prod watch` en background, que a su vez llama `ensure_alive()` cada 5s para detectar y reiniciar cualquier servicio muerto. El servicio se inicia automáticamente con el sistema (RunAtLoad=true).
|
||||
|
||||
**Logs del watchdog:**
|
||||
- stdout/stderr → `~/.mdv-watchdog.log` y `~/.mdv-watchdog.err`
|
||||
|
||||
## Build Required
|
||||
|
||||
Después de mergear, ejecutar:
|
||||
```bash
|
||||
cd project && npm run build
|
||||
```
|
||||
|
||||
## Verification
|
||||
|
||||
```bash
|
||||
# Verificar servicios
|
||||
./project/scripts/monolith.sh prod status
|
||||
|
||||
# Verificar que el watchdog corre
|
||||
launchctl list | grep monolith
|
||||
|
||||
# Ver logs del watchdog
|
||||
tail -f ~/.mdv-watchdog.log
|
||||
```
|
||||
|
||||
## Files Changed
|
||||
- `project/src/infrastructure/http/server.ts` — heartbeat agregado
|
||||
- `platforms/macos/com.mercadodevida.monolith-watchdog.plist` — nuevo
|
||||
- `scripts/install-watchdog.sh` — nuevo

## F-054 — Backend muere sin rastro y auth/login devuelve 502/500
|
||||
|
||||
Backlog: 121 features (118 done + F-051, F-052, F-053 pending).
|
||||
**Status:** in_progress
|
||||
**Type:** fix
|
||||
**Priority:** high
|
||||
**Created:** 2026-08-19T08:52:44Z
|
||||
|
||||
## Tickets pendientes
|
||||
### Problema
|
||||
El backend (`dist/infrastructure/http/server.js`) muere sin dejar trazas en el log y deja a admin/frontend sin API. Síntoma: `/api/auth/login` devuelve 502 (admin proxy) o 500 (frontend route handler) cuando el backend no responde. Causa raíz desconocida.
|
||||
|
||||
| ID | Título | Prioridad |
|
||||
|-----|--------|-----------|
|
||||
| F-051 | Favicon 404 en storefront y admin | medium |
|
||||
| F-052 | Imágenes de producto 404 en frontend/storefront | high |
|
||||
| F-053 | Category selector desalineado en admin | low |
|
||||
### Mejoras requeridas
|
||||
1. Investigar por qué muere el backend
|
||||
2. Hacer que `monolith.sh` detecte y reinicie el backend si muere
|
||||
3. Usar `process.env.NEXT_PUBLIC_API_URL` en `frontend/src/app/api/auth/login/route.ts` en lugar de hardcodear `http://127.0.0.1:3000`

## Credenciales backoffice
|

- `admin@mercadodevida.com` / `Admin1234`
|
||||
- `info@rikrdo.es` (hash histórico)
|
||||
|
||||
## Diagnóstico rápido
|
||||
|
||||
### Favicon 404 (F-051)
|
||||
- `curl 3003/favicon.ico` → 200 (frontend OK)
|
||||
- `curl 3004/favicon.ico` → 404 (admin KO)
|
||||
- `curl 3005/favicon.ico` → 404 (storefront KO)
|
||||
- Solución: copiar favicon a storefront/admin public/ y añadir link en layouts.
|
||||
### F-054: Backend 502/500
|
||||
- Backend muere sin trazas → buscar en logs o journal
|
||||
- monolith.sh debería detectar muerte y reiniciar
|
||||
- API URL hardcodeada en frontend login route
|
||||
|
||||
### Imágenes producto 404 (F-052)
|
||||
- `curl 3003/uploads/...jpg` → 404 (frontend KO)
|
||||
- Archivos en `apps/admin/public/uploads/`, no en frontend/storefront.
|
||||
- Solución: copiar uploads a frontend/storefront public/ o añadir ruta /uploads/ en backend.
|
||||
|
||||
### Category selector (F-053)
|
||||
- Grid 2 columnas en categories/page.tsx: select + checkbox flex.
|
||||
- Checkbox no ocupa todo el ancho y está desalineado.
|
||||
|
||||
### 502 api/products (¿F-054?)
|
||||
- Probablemente rate-limiting del backend (TOO_MANY_ATTEMPTS tras pruebas de login).
|
||||
- Si persiste, crear ticket.
|
||||
### Credenciales backoffice
|
||||
- `admin@mercadodevida.com` / `Admin1234`
|
||||
