From a4ca6e8ea668c8f80d64271d00428010bb236c0c Mon Sep 17 00:00:00 2001 From: pacnpal <183241239+pacnpal@users.noreply.github.com> Date: Sat, 16 Nov 2024 05:01:29 +0000 Subject: [PATCH] Core Systems: Component-based architecture with lifecycle management Enhanced error handling and recovery mechanisms Comprehensive state management and tracking Event-driven architecture with monitoring Queue Management: Multiple processing strategies for different scenarios Advanced state management with recovery Comprehensive metrics and health monitoring Sophisticated cleanup system with multiple strategies Processing Pipeline: Enhanced message handling with validation Improved URL extraction and processing Better queue management and monitoring Advanced cleanup mechanisms Overall Benefits: Better code organization and maintainability Improved error handling and recovery Enhanced monitoring and reporting More robust and reliable system --- videoarchiver/config/channel_manager.py | 225
