**Version:** 1.0
|
**Version:** 2.0
|
||||||
**Date:** 2026-01-18
|
**Date:** 2026-01-24
|
||||||
**Status:** Planning Phase
|
**Status:** ✅ Implemented with Concurrent Processing
|
||||||
|
|
||||||
|
## ⚡ Update 2.0 - Concurrent Processing (2026-01-24)
|
||||||
|
|
||||||
|
**Enhancement**: Added support for concurrent processing of multiple anime additions.
|
||||||
|
|
||||||
|
### Changes Made
|
||||||
|
|
||||||
|
1. **Multiple Worker Architecture**:
|
||||||
|
- Changed from single worker to configurable multiple workers (default: 5)
|
||||||
|
- Multiple anime can now be processed simultaneously
|
||||||
|
- Non-blocking queue processing allows immediate response to additional requests
|
||||||
|
|
||||||
|
2. **Backward Compatibility**:
|
||||||
|
- All existing APIs remain unchanged
|
||||||
|
- Drop-in replacement for single-worker implementation
|
||||||
|
- Tests updated to reflect concurrent behavior
|
||||||
|
|
||||||
|
3. **Configuration**:
|
||||||
|
- `max_concurrent_loads` parameter added to control worker count
|
||||||
|
- Default set to 5 concurrent loads for optimal balance
|
||||||
|
|
||||||
|
4. **Performance Impact**:
|
||||||
|
- Multiple anime additions now process in parallel
|
||||||
|
- No blocking when adding second anime while first is loading
|
||||||
|
- Each worker processes tasks independently from queue
|
||||||
|
|
||||||
|
### Migration Notes
|
||||||
|
|
||||||
|
- **Attribute Change**: `worker_task` → `worker_tasks` (now a list)
|
||||||
|
- **Stop Behavior**: Gracefully stops all workers with proper cleanup
|
||||||
|
- **Tests**: Updated to verify concurrent processing

|
## TODO List:
|
||||||
|
|
||||||
✅ **COMPLETED (1):** Fixed greenlet_spawn async lazy-loading error - Added selectinload for episode relationship in DownloadQueueService.get_all()
|
### Completed ✅
|
||||||
|
|
||||||
✅ **COMPLETED (2):** Fixed anime add endpoint 500 error - Added explicit commit/rollback in database session dependencies
|
1. **Fast adding - Concurrent Anime Processing (Completed 2026-01-24)**
|
||||||
|
- **What was done:**
|
||||||
|
- Modified `BackgroundLoaderService` to support concurrent processing with multiple workers
|
||||||
|
- Added configurable `max_concurrent_loads` parameter (default: 5)
|
||||||
|
- Multiple anime can now be added and processed in parallel without blocking
|
||||||
|
- Created comprehensive unit tests verifying concurrent behavior
|
||||||
|
- Updated integration tests for compatibility
|
||||||
|
- Updated architecture documentation
|
||||||
|
- **Result:** Multiple anime additions now process simultaneously. Users can add second anime immediately while first is still loading.
|
||||||
|
- **Tests:** `tests/unit/test_parallel_anime_add.py`, integration tests updated
|
||||||
|
- **Files Changed:**
|
||||||
|
- `src/server/services/background_loader_service.py`
|
||||||
|
- `tests/unit/test_parallel_anime_add.py` (new)
|
||||||
|
- `tests/integration/test_async_series_loading.py` (updated)
|
||||||
|
- `docs/architecture/async_loading_architecture.md` (updated)
|
||||||
|
|
||||||
✅ **COMPLETED (3):** Added database transactions - All database operations properly use session context managers with automatic commit/rollback
|
### In Progress 🔄
|
||||||
|
|
||||||
✅ **COMPLETED (4):** Created series filter to filter all series with no episodes found in folder - Added `filter=no_episodes` parameter to list_anime endpoint and get_series_with_no_episodes() database method
