-#### Integration - -The ScanService integrates with: -- `ProgressService`: For progress tracking and WebSocket broadcasting -- `SerieScanner` (core): For actual scan operations via callbacks -- `CallbackManager` (core): For receiving progress/error/completion events - -#### Usage Example - -```python -from src.server.services.scan_service import get_scan_service - -# Get singleton instance -scan_service = get_scan_service() - -# Subscribe to scan events -async def handle_scan_event(event_data): - print(f"Scan event: {event_data['type']}") - if 'key' in event_data: - print(f"Series key: {event_data['key']}") - -scan_service.subscribe_to_scan_events(handle_scan_event) - -# Start a scan (factory creates SerieScanner with callbacks) -scan_id = await scan_service.start_scan(scanner_factory) -

Health check endpoints - - `src/server/controllers/page_controller.py` - HTML page routes - - `src/server/controllers/error_controller.py` - Error handling controllers - -2. **Shared Template Configuration**: - - - `src/server/utils/templates.py` - Centralized Jinja2 template configuration - - Fixed template path resolution for proper template loading - -3. **Main Application Updates**: - - - `src/server/fastapi_app.py` - Refactored to use controller routers - - Removed direct route definitions from main file - - Added router inclusion using `app.include_router()` - - Simplified error handlers to delegate to controller functions - -4. **Fixed Import Issues**: - - Resolved circular import in `src/core/__init__.py` - - Removed non-existent `application` module import - -#### Controller Architecture - -### Anime Service Notes - -- The new `anime_service` runs the existing blocking `SeriesApp` inside a - threadpool (via ThreadPoolExecutor). This keeps the FastAPI event loop - responsive while leveraging the existing core logic. -- A small in-process LRU cache is used for the frequently-read "missing - episodes" list to reduce IO; cache invalidation happens after a rescan. -- For multi-worker or multi-host deployments, move cache/state to a shared - store (Redis) and ensure the threadpool sizing matches the worker's CPU - and IO profile. - -**Health Controller** (`health_controller.py`): - -```python -router = APIRouter(prefix="/health", tags=["health"]) -@router.get("") - Health check endpoint -``` - -**Page Controller** (`page_controller.py`): - -```python -router = APIRouter(tags=["pages"]) -@router.get("/") - Main application page -@router.get("/setup") - Setup page -@router.get("/login") - Login page -@router.get("/queue") - Download queue page -``` - -**Error Controller** (`error_controller.py`): - -```python -async def not_found_handler() - Custom 404 error handling -async def server_error_handler() - Custom 500 error handling -``` - -#### Benefits of the New Structure - -- **Separation of Concerns**: Each controller handles specific functionality -- **Modularity**: Easy to add new controllers and routes -- **Testability**: Controllers can be tested independently -- **Maintainability**: Cleaner code organization and easier debugging -- **Scalability**: Simple to extend with new features - -#### Verified Working Endpoints - -All endpoints tested and confirmed working: - -- Health: `/health` → Returns `{"status": "healthy", ...}` -- Root: `/` → Serves main application page -- Setup: `/setup` → Serves setup page -- Auth API: `/api/auth/*` → Endpoints for setup, login, logout and status (JWT-based) -- Login: `/login` → Serves login page -- Queue: `/queue` → Serves download queue page - -#### File Structure After Refactoring - -``` -src/server/ -├── fastapi_app.py # Main FastAPI application (simplified) -├── controllers/ # NEW: Route controllers -│ ├── __init__.py # Controllers package -├── utils/ -│ ├── dependencies.py # Existing dependency injection -│ └── templates.py # NEW: Shared Jinja2 template config -└── web/ # Existing frontend assets - ├── templates/ # HTML templates - └── static/ # CSS, JS, images -``` - -### Authentication Middleware (October 2025) - -An authentication middleware component was added to the FastAPI -application to centralize token parsing and provide lightweight -protection of authentication endpoints: - -- `src/server/middleware/auth.py` implements: - - Bearer JWT parsing and session attachment to `request.state.session` - - A simple per-IP in-memory rate limiter applied to - `/api/auth/login` and `/api/auth/setup` (default 5 requests/minute) - -Notes: - -- This is intentionally simple and designed for single-process - deployments. For production use across multiple workers or hosts, - replace the in-memory limiter with a distributed store (e.g. Redis) - and add a persistent token revocation list if needed. - -### API Models and Contracts - -- Pydantic models living in `src/server/models/` define the canonical - API contracts used by FastAPI endpoints. These models are intentionally - lightweight and focused on serialization, validation, and OpenAPI - documentation generation. -- Keep models stable: changes to model shapes are breaking changes for - clients. Bump API versioning or provide migration layers when altering - public response fields. -- Infrastructure considerations: ensure the deployment environment has - required libraries (e.g., `pydantic`) installed and that schema - validation errors are logged to the centralized logging system. For - high-throughput routes, consider response model caching at the - application or reverse-proxy layer. - -### WebSocket Real-time Communication (October 2025) - -A comprehensive WebSocket infrastructure was implemented to provide real-time -updates for downloads, queue status, and system events: - -- **File**: `src/server/services/websocket_service.py` -- **Models**: `src/server/models/websocket.py` -- **Endpoint**: `ws://host:port/ws/connect` - -#### WebSocket Service Architecture - -- **ConnectionManager**: Low-level connection lifecycle management - - - Connection registry with unique connection IDs - - Room-based messaging for topic subscriptions - - Automatic connection cleanup and health monitoring - - Thread-safe operations with asyncio locks - -- **WebSocketService**: High-level application messaging - - Convenient interface for broadcasting application events - - Pre-defined message types for downloads, queue, and system events - - Singleton pattern via `get_websocket_service()` factory - -#### Supported Message Types - -- **Download Events**: `download_progress`, `download_complete`, `download_failed` -- **Queue Events**: `queue_status`, `queue_started`, `queue_stopped`, `queue_paused`, `queue_resumed` -- **System Events**: `system_info`, `system_warning`, `system_error` -- **Connection**: `connected`, `ping`, `pong`, `error` - -#### Room-Based Messaging - -Clients can subscribe to specific topics (rooms) to receive targeted updates: - -- `downloads` room: All download-related events -- Custom rooms: Can be added for specific features - -#### Integration with Download Service - -- Download service automatically broadcasts progress updates via WebSocket -- Broadcast callback registered during service initialization -- Updates sent to all clients subscribed to the `downloads` room -- No blocking of download operations (async broadcast) - -#### Client Connection Flow - -1. Client connects to `/ws/connect` endpoint -2. Server assigns unique connection ID and sends confirmation -3. Client joins rooms (e.g., `{"action": "join", "room": "downloads"}`) -4. Server broadcasts updates to subscribed rooms -5. Client disconnects (automatic cleanup) - -#### Infrastructure Notes - -- **Single-process**: Current implementation uses in-memory connection storage -- **Production**: For multi-worker/multi-host deployments: - - Move connection registry to Redis or similar shared store - - Implement pub/sub for cross-process message broadcasting - - Add connection persistence for recovery after restarts -- **Monitoring**: WebSocket status available at `/ws/status` endpoint -- **Security**: Optional authentication via JWT (user_id tracking) -- **Testing**: Comprehensive unit tests in `tests/unit/test_websocket_service.py` - -### Download Queue Models - -- Download queue models in `src/server/models/download.py` define the data - structures for the download queue system. -- Key models include: - - `DownloadItem`: Represents a single queued download with metadata, - progress tracking, and error information - - `QueueStatus`: Overall queue state with active, pending, completed, - and failed downloads - - `QueueStats`: Aggregated statistics for monitoring queue performance - - `DownloadProgress`: Real-time progress information (percent, speed, - ETA) - - `DownloadRequest`/`DownloadResponse`: API request/response contracts -- Models enforce validation constraints (e.g., positive episode numbers, - progress percentage 0-100, non-negative retry counts) and provide - clean JSON serialization for API endpoints and WebSocket updates. - -### Download Queue Service - -- The download service (`src/server/services/download_service.py`) manages - the complete lifecycle of anime episode downloads. -- Core features: - - **Priority-based Queue**: Items added with HIGH priority are processed - first, NORMAL and LOW follow in FIFO order - - **Concurrent Processing**: Configurable max concurrent downloads (default 2) - to optimize bandwidth usage - - **Persistence**: Queue state is automatically saved to - `data/download_queue.json` and recovered on service restart - - **Retry Logic**: Failed downloads are automatically retried up to a - configurable limit (default 3 attempts) with exponential backoff - - **Progress Tracking**: Real-time download progress with speed, - percentage, and ETA calculations - - **WebSocket Integration**: Broadcasts queue updates, progress, and - completion/failure events to connected clients -- Operations: - - `add_to_queue()`: Add episodes to download queue with priority - - `remove_from_queue()`: Cancel pending or active downloads - - `reorder_queue()`: Manually adjust queue order for pending items - - `pause_queue()`/`resume_queue()`: Control download processing - - `retry_failed()`: Retry failed downloads with retry count checks - - `get_queue_status()`: Get complete queue state (active, pending, completed, failed) - - `get_queue_stats()`: Get aggregated statistics (counts, download size, speed) -- Infrastructure notes: - - Service uses ThreadPoolExecutor for concurrent download processing - - Queue processor runs as async background task with configurable sleep intervals - - Progress callbacks are executed in threadpool and broadcast via async WebSocket - - For multi-process deployments, move queue state to shared store (Redis/DB) - and implement distributed locking for concurrent access control - - Singleton instance pattern used via `get_download_service()` factory -- Testing: Comprehensive unit tests in `tests/unit/test_download_service.py` - cover queue operations, persistence, retry logic, and error handling - -#### Series Identifier Standardization (November 2025) - -**Task 3.1 Completed**: Updated DownloadService to use standardized series identifiers. - -**Changes Made**: - -- **serie_id Field**: Now explicitly documented as the provider key - (e.g., "attack-on-titan"). This is the unique, URL-safe identifier - used for all series lookups and identification throughout the system. -- **serie_folder Field**: Changed from Optional to required. This field - contains the filesystem folder name (e.g., "Attack on Titan (2013)") - and is used exclusively for filesystem operations. -- **Separation of Concerns**: Removed incorrect fallback logic that - used `serie_id` as a substitute for `serie_folder`. These fields now - serve distinct purposes and must both be provided. -- **Enhanced Documentation**: Updated docstrings in `add_to_queue()` - method and all Pydantic models to clarify the purpose and usage of - each identifier field. -- **Improved Logging**: Updated log statements to reference `serie_key` - for identification, making it clear which identifier is being used. - -**Models Updated**: - -- `DownloadItem` (src/server/models/download.py): - - `serie_id`: Required field with provider key - - `serie_folder`: Changed from Optional to required - - Both fields have enhanced field descriptions -- `DownloadRequest` (src/server/models/download.py): - - `serie_folder`: Changed from Optional to required - - Enhanced field descriptions for both identifiers - -**Service Changes**: - -- `DownloadService.add_to_queue()`: Updated to validate that - `serie_folder` is always provided and raises DownloadServiceError - if missing -- Removed fallback logic: `folder = item.serie_folder if item.serie_folder else item.serie_id` -- Added validation check before download execution -- Updated logging to use `serie_key` parameter name - -**Testing**: - -- Updated all test fixtures to include required `serie_folder` field -- All 25 download service tests passing -- All 47 download model tests passing - -**Benefits**: - -- Clear separation between provider identifier (key) and filesystem path (folder) -- Prevents confusion and potential bugs from mixing identifiers -- Consistent with broader series identifier standardization effort -- Better error messages when required fields are missing - -### Download Queue API Endpoints (October 2025) - -Implemented comprehensive REST API endpoints for download queue management: - -- **File**: `src/server/api/download.py` -- **Router Prefix**: `/api/queue` -- **Authentication**: All endpoints require JWT authentication via `require_auth` dependency -

-- `items_added` - Items added to queue - - Data: added_ids, queue_status (complete queue state) -- `items_removed` - Items removed/cancelled - - Data: removed_ids, queue_status -- `queue_reordered` - Queue order changed - - Data: item_id, new_position, queue_status -- `items_retried` - Failed items retried - - Data: retried_ids, queue_status -- `completed_cleared` - Completed items cleared - - Data: cleared_count, queue_status - -**Queue Control Broadcasting**: - -- `queue_started` - Queue processor started - - Data: is_running=True, queue_status -- `queue_stopped` - Queue processor stopped - - Data: is_running=False, queue_status -- `queue_paused` - Queue processing paused - - Data: is_paused=True, queue_status -- `queue_resumed` - Queue processing resumed - - Data: is_paused=False, queue_status - -**Broadcast Callback Setup**: -The download service broadcast callback is registered during dependency injection in `src/server/utils/dependencies.py`: - -- Maps update types to WebSocket service methods -- Routes download_progress, download_complete, download_failed to appropriate rooms -- All queue operations broadcast complete queue status for client synchronization - -#### AnimeService WebSocket Integration - -**File**: `src/server/services/anime_service.py` - -The anime service integrates with ProgressService for library scan operations: - -**Scan Progress Broadcasting**: - -- Scan operations use ProgressService for progress tracking -- Progress updates broadcast to `scan_progress` room -- Lifecycle events: - - `started` - Scan initialization - - `in_progress` - Ongoing scan with current/total file counts - - `completed` - Successful scan completion - - `failed` - Scan failure with error message - -**Scan Implementation**: - -- `rescan()` method wraps SeriesApp.ReScan with progress tracking -- Progress callback executed in threadpool updates ProgressService -- ProgressService automatically broadcasts to WebSocket clients -- Cache invalidation on successful scan completion - -#### ProgressService WebSocket Integration - -**File**: `src/server/services/progress_service.py` - -Central service for tracking and broadcasting all progress operations: - -**Progress Types**: - -- `DOWNLOAD` - File download progress -- `SCAN` - Library scan progress -- `QUEUE` - Queue operation progress -- `SYSTEM` - System-level operations -- `ERROR` - Error notifications - -**Progress Lifecycle**: - -1. `start_progress()` - Initialize progress operation - - Broadcasts to room: `{progress_type}_progress` -2. `update_progress()` - Update progress values - - Calculates percentage automatically - - Broadcasts only on significant changes (>1% or forced) -3. `complete_progress()` - Mark operation complete - - Sets progress to 100% - - Moves to history - - Broadcasts completion -4. `fail_progress()` - Mark operation failed - - Captures error message - - Moves to history - - Broadcasts failure - -**Broadcast Callback**: - -- Callback registered during application startup in `src/server/fastapi_app.py` -- Links ProgressService to WebSocketService.manager.broadcast_to_room -- All progress updates automatically broadcast to appropriate rooms - -#### WebSocket Room Structure - -Clients subscribe to specific rooms to receive targeted updates: - -**Room Types**: - -- `downloads` - All download-related events (complete, failed, queue status) -- `download_progress` - Real-time download progress updates -- `scan_progress` - Library scan progress updates -- `queue_progress` - Queue operation progress (future use) -- `system_progress` - System-level progress (future use) - -**Room Subscription**: -Clients join rooms by sending WebSocket messages: - -```json -{ - "action": "join", - "room": "download_progress" -} -``` - -#### Message Format - -All WebSocket messages follow a consistent structure: - -```json -{ - "type": "download_progress" | "download_complete" | "queue_status" | etc., - "timestamp": "2025-10-17T12:34:56.789Z", - "data": { - // Message-specific data - } -} -``` - -**Example: Download Progress** - -```json -{ - "type": "download_progress", - "timestamp": "2025-10-17T12:34:56.789Z", - "data": { - "download_id": "abc123", - "serie_name": "Attack on Titan", - "season": 1, - "episode": 5, - "progress": { - "percent": 45.2, - "downloaded_mb": 226.0, - "total_mb": 500.0, - "speed_mbps": 2.5, - "eta_seconds": 120 - } - } -} -``` - -**Example: Queue Status** - -```json -{ - "type": "queue_status", - "timestamp": "2025-10-17T12:34:56.789Z", - "data": { - "action": "items_added", - "added_ids": ["item1", "item2"], - "queue_status": { - "is_running": true, - "is_paused": false, - "active_downloads": [...], - "pending_queue": [...], - "completed_downloads": [...], - "failed_downloads": [...] - } - } -} -``` - -#### Integration Testing - -**File**: `tests/integration/test_websocket_integration.py` - -Comprehensive integration tests verify WebSocket broadcasting: - -**Test Coverage**: - -- Download progress broadcasts during active downloads -- Queue operation broadcasts (add, remove, reorder, clear, retry) -- Queue control broadcasts (start, stop, pause, resume) -- Scan progress broadcasts (start, update, complete, fail) -- Progress lifecycle broadcasts for all operation types -- End-to-end flow with multiple services broadcasting - -**Test Strategy**: - -- Mock broadcast callbacks to capture emitted messages -- Verify message types, data structure, and content -- Test both successful and failure scenarios -- Verify proper room routing for different message types - -#### Architecture Benefits - -**Decoupling**: - -- Services use generic broadcast callbacks without WebSocket dependencies -- ProgressService provides abstraction layer for progress tracking -- Easy to swap WebSocket implementation or add additional broadcast targets - -**Consistency**: - -- All services follow same broadcast patterns -- Standardized message formats across application -- Unified progress tracking via ProgressService - -**Real-time UX**: - -- Instant feedback on all long-running operations -- Live queue status updates -- Progress bars update smoothly without polling -- Error notifications delivered immediately - -**Scalability**: - -- Room-based messaging enables targeted updates -- Multiple concurrent operations supported -- Easy to add new progress types and message formats - -#### Production Considerations - -**Single-Process Deployment** (Current): - -- In-memory connection registry in WebSocketService -- Works perfectly for single-worker deployments -- No additional infrastructure required - -**Multi-Process/Multi-Host Deployment** (Future): - -- Move connection registry to Redis or similar shared store -- Implement pub/sub for cross-process message broadcasting -- Add connection persistence for recovery after restarts -- Consider using sticky sessions or connection migration - -**Performance**: - -- Progress updates throttled to >1% changes to reduce message volume -- Broadcast operations are fire-and-forget (non-blocking) -- Failed connections automatically cleaned up -- Message serialization cached where possible - -**Monitoring**: - -- Structured logging for all broadcast operations -- WebSocket status available at `/ws/status` endpoint -- Connection count and room membership tracking -- Error tracking for failed broadcasts - -### Frontend Authentication Integration (October 2025) - -Completed JWT-based authentication integration between frontend and backend. - -#### Authentication Token Storage - -**Files Modified:** - -- `src/server/web/templates/login.html` - Store JWT token after successful login -- `src/server/web/templates/setup.html` - Redirect to login after setup completion -- `src/server/web/static/js/app.js` - Include Bearer token in all authenticated requests -- `src/server/web/static/js/queue.js` - Include Bearer token in queue API calls - -**Implementation:** - -- JWT tokens stored in `localStorage` after successful login -- Token expiry stored in `localStorage` for client-side validation -- `Authorization: Bearer ` header included in all authenticated requests -- Automatic redirect to `/login` on 401 Unauthorized responses -- Token cleared from `localStorage` on logout - -**Key Functions Updated:** - -- `makeAuthenticatedRequest()` in both `app.js` and `queue.js` -- `checkAuthentication()` to verify token and redirect if missing/invalid -- `logout()` to clear token and redirect to login - -### Frontend API Endpoint Updates (October 2025) - -Updated frontend JavaScript to match new backend API structure. - -**Queue Management API Changes:** - -- `/api/queue/clear` → `/api/queue/completed` for clearing completed downloads -- `/api/queue/remove` → `/api/queue/{item_id}` (DELETE) for single item removal -- `/api/queue/retry` payload changed to `{item_ids: []}` array format -- `/api/download/pause` → `/api/queue/pause` -- `/api/download/resume` → `/api/queue/resume` -- `/api/download/cancel` → `/api/queue/stop` - -**Response Format Changes:** - -- Login returns `{access_token, token_type, expires_at}` instead of `{status: 'success'}` -- Setup returns `{status: 'ok'}` instead of `{status: 'success', redirect_url}` -- Logout returns `{status: 'ok'}` instead of `{status: 'success'}` -- Queue operations return structured responses with counts (e.g., `{cleared_count, retried_count}`) - -### Frontend WebSocket Integration (October 2025) - -WebSocket integration previously completed and verified functional. - -#### Native WebSocket Implementation - -**Files:** - -- `src/server/web/static/js/websocket_client.js` - Native WebSocket wrapper -- Templates already updated to use `websocket_client.js` instead of Socket.IO - -**Event Compatibility:** - -- Dual event handlers in place for backward compatibility -- Old events: `scan_completed`, `scan_error`, `download_completed`, `download_error` -- New events: `scan_complete`, `scan_failed`, `download_complete`, `download_failed` -- Both event types supported simultaneously - -**Room Subscriptions:** - -- `downloads` - Download completion, failures, queue status -- `download_progress` - Real-time download progress updates -- `scan_progress` - Library scan progress updates - -### Frontend Integration Testing (October 2025) - -Created smoke tests to verify frontend-backend integration. - -**Test File:** `tests/integration/test_frontend_integration_smoke.py` - -**Tests:** - -- JWT token format verification (access_token, token_type, expires_at) -- Bearer token authentication on protected endpoints -- 401 responses for requests without valid tokens - -**Test Results:** - -- Basic authentication flow: ✅ PASSING -- Token validation: Functional with rate limiting considerations - -### Frontend Integration (October 2025) - -Completed integration of existing frontend JavaScript with the new FastAPI backend and native WebSocket implementation. - -#### Native WebSocket Client - -**File**: `src/server/web/static/js/websocket_client.js` - -Created a Socket.IO-compatible wrapper using native WebSocket API: - -**Features**: - -- Socket.IO-style `.on()` and `.emit()` methods for compatibility -- Automatic reconnection with exponential backoff (max 5 attempts) -- Room-based subscriptions via `.join()` and `.leave()` methods -- Message queueing during disconnection -- Proper connection lifecycle management -
