From b0f3b643c723cd308b18e82b431a64b10078866c Mon Sep 17 00:00:00 2001 From: Lukas Date: Tue, 2 Dec 2025 16:01:25 +0100 Subject: [PATCH] Migrate download queue from JSON to SQLite database - Created QueueRepository adapter in src/server/services/queue_repository.py - Refactored DownloadService to use repository pattern instead of JSON - Updated application startup to initialize download service from database - Updated all test fixtures to use MockQueueRepository - All 1104 tests passing --- data/config.json | 23 + .../config_backup_20251202_155022.json | 23 +

Task 1: Create Database Queue Repository Adapter - -**File:** `src/server/services/queue_repository.py` - -**Objective:** Create a repository adapter that wraps `DownloadQueueService` and provides the interface needed by `DownloadService`. - -**Requirements:** - -- [ ] Create `QueueRepository` class with async methods -- [ ] Implement `save_item(item: DownloadItem) -> DownloadItem` -- [ ] Implement `get_item(item_id: str) -> Optional[DownloadItem]` -- [ ] Implement `get_pending_items() -> List[DownloadItem]` -- [ ] Implement `get_active_item() -> Optional[DownloadItem]` -- [ ] Implement `get_completed_items(limit: int) -> List[DownloadItem]` -- [ ] Implement `get_failed_items(limit: int) -> List[DownloadItem]` -- [ ] Implement `update_status(item_id: str, status: DownloadStatus, error: Optional[str]) -> bool` -- [ ] Implement `update_progress(item_id: str, progress: float, downloaded: int, total: int, speed: float) -> bool` -- [ ] Implement `delete_item(item_id: str) -> bool` -- [ ] Implement `clear_completed() -> int` -- [ ] Convert between `DownloadItem` (Pydantic model) and `DownloadQueueItem` (SQLAlchemy model) -- [ ] Handle database session management properly -- [ ] Add proper error handling and logging - -**Acceptance Criteria:** - -- Repository provides clean interface for queue operations -- All database operations are properly async -- Proper error handling for database failures -- Type hints for all methods - ---- - -### Task 2: Refactor DownloadService to Use Repository Pattern - -**File:** `src/server/services/download_service.py` - -**Objective:** Replace JSON file persistence with the new `QueueRepository`. - -**Requirements:** - -- [ ] Inject `QueueRepository` via constructor -- [ ] Remove `_persistence_path` attribute and JSON file handling -- [ ] Remove `_load_queue()` JSON loading method -- [ ] Remove `_save_queue()` JSON saving method -- [ ] Replace in-memory `deque` storage with database calls for persistence -- [ ] Keep in-memory cache for active operations (performance) -- [ ] Implement `_sync_from_database()` method for startup initialization -- [ ] Update `add_to_queue()` to save to database -- [ ] Update `_process_download()` to update database on status changes -- [ ] Update progress tracking to persist to database -- [ ] Update `remove_from_queue()` to delete from database -- [ ] Update `clear_completed()` to clear from database -- [ ] Ensure graceful shutdown persists final state - -**Acceptance Criteria:** - -- No JSON file operations remain in DownloadService -- Queue state persists across server restarts via SQLite -- Active downloads recover correctly after restart -- Performance remains acceptable (use caching where needed) -- All existing functionality preserved - ---- - -### Task 3: Update Dependency Injection and Application Startup - -**File:** `src/server/fastapi_app.py` and related files - -**Objective:** Wire up the new database-backed queue system. - -**Requirements:** - -- [ ] Update `DownloadService` initialization to use `QueueRepository` -- [ ] Ensure database session is available for queue operations -- [ ] Update any direct `DownloadService` instantiation -- [ ] Remove references to JSON persistence path configuration -- [ ] Update health check endpoints if they reference queue file - -**Acceptance Criteria:** - -- Application starts successfully with database-backed queue -- No JSON file references remain in startup code -- Dependency injection properly configured - ---- - -### Task 4: Update API Endpoints for Database-Backed Queue - -**File:** `src/server/api/download_routes.py` (or equivalent) - -**Objective:** Ensure all download API endpoints work with database-backed queue. - -**Requirements:** - -- [ ] Verify `GET /api/queue` returns items from database -- [ ] Verify `POST /api/queue` adds items to database -- [ ] Verify `DELETE /api/queue/{id}` removes from database -- [ ] Verify queue statistics reflect database state -- [ ] Verify WebSocket broadcasts still work correctly -- [ ] Update any endpoint that directly accessed JSON file -- [ ] Add new endpoint `GET /api/queue/history` for completed/failed items (optional) - -**Acceptance Criteria:** - -- All existing API contracts maintained -- Queue operations reflect database state -- Real-time updates via WebSocket work correctly +- **Task 1**:
