Sequential component initialization
Coordination through an _initialized event
Consistent lock hierarchy with _global_lock
Updated the base cog to properly initialize components:
Added timeout handling for queue manager initialization
Ensures queue manager is fully initialized before starting queue processing
Added proper error handling and cleanup
Established consistent lock ordering:
Global Lock -> Queue Lock -> Processing Lock
Prevents circular wait conditions
Each component respects the lock hierarchy
Improved task coordination:
Sequential initialization of components
Proper waiting for initialization before starting operations
Timeout handling for all async operations
Removed all duplicate code and unnecessary operations
Proper error handling with clean structure
Efficient state management with locks
No unnecessary persistence or sleep calls
Improved queue processing:
Batch processing up to 5 items at a time
Concurrent processing using asyncio.create_task
Proper yielding of control between operations
Less frequent state persistence (60s intervals)
Shorter sleep times (0.1s) when queue is empty
Better resource management:
Proper task tracking and cleanup
Efficient error recovery
Clean state persistence
Proper lock usage to prevent race conditions
Modified the initialization process to start queue processing as a non-blocking background task
Added proper cleanup of the queue task during cog unload
Optimized the queue manager's process_queue method to:
Use shorter sleep times (0.1s) when queue is empty
Persist state less frequently (every 60s)
Better handle task switching with asyncio.sleep(0)
Improve error recovery with brief pauses
These changes resolve both the initial "process_video missing" error and the subsequent "initialization timeout" error by:
Properly implementing the missing method
Making queue processing non-blocking during initialization
Ensuring proper cleanup of all tasks
Optimizing the queue processing loop for better performance
Adding proper processing state tracking and timing
Implementing more aggressive monitoring (1-minute intervals)
Adding activity tracking to detect and recover from hung states
Improving error handling and logging throughout the system
Reducing timeouts and deadlock thresholds for faster recovery
- Created new queue module with separate components:
- models.py: QueueItem and QueueMetrics data classes
- persistence.py: Queue state persistence
- monitoring.py: Health monitoring and metrics
- cleanup.py: Cleanup operations
- manager.py: Main queue management
- __init__.py: Package exports
- Updated imports in video_archiver.py and processor.py
- Removed old enhanced_queue.py
- Updated README with new queue system details
This refactoring improves code organization and maintainability
through better separation of concerns while maintaining all
existing functionality.
