- Write ERROR via ownership check OR state guard fallback when ownership TTL expired during retries
- Add INITIALIZING to cleanup task grace period monitoring
- Validate client SET entries against metadata hashes in orphaned channel cleanup; remove ghosts and clean up when no real clients remain
- Stats page self-heals by removing ghost SET entries on read
- Extract remove_ghost_clients() helper to ClientManager
- Add ChannelState.PRE_ACTIVE constant
- Fix 6 pre-existing NonOwnerWorkerKeepalive test failures
System Event Logging:
- Add SystemEvent model with 15 event types tracking channel operations, client connections, M3U/EPG activities, and buffering events
- Log detailed metrics for M3U/EPG refresh operations (streams/programs created/updated/deleted)
- Track M3U/EPG downloads with client information (IP address, user agent, profile, channel count)
- Record channel lifecycle events (start, stop, reconnect) with stream and client details
- Monitor client connections/disconnections and buffering events with stream metadata
Event Viewer UI:
- Add SystemEvents component with real-time updates via WebSocket
- Implement pagination, filtering by event type, and configurable auto-refresh
- Display events with color-coded badges and type-specific icons
- Integrate event viewer into Stats page with modal display
- Add event management settings (retention period, refresh rate)
M3U/EPG Endpoint Optimizations:
- Implement content caching with 5-minute TTL to reduce duplicate processing
- Add client-based event deduplication (2-second window) using IP and user agent hashing
- Support HEAD requests for efficient preflight checks
- Cache streamed EPG responses while maintaining streaming behavior for first request
Improved try_next_stream to not fail if the returned stream is the same. It will now try a different stream.
Force a client to jump ahead in the buffer if they fall to far behind.
- Introduced _wait_for_existing_processes_to_close method to ensure all existing processes and connections are fully closed before establishing new ones.
- Updated _establish_transcode_connection and _establish_http_connection methods to check for and close lingering processes and connections.
- Enhanced logging for better debugging and monitoring of connection states.
