- Enable gevent cooperative multitasking in all uWSGI worker configs
(gevent-early-monkey-patch + import dispatcharr.gevent_patch)
- Rewrite WebSocket group sends to bypass asyncio in gevent workers:
_gevent_ws_send() replicates the channels_redis 4.x wire format
directly via synchronous Redis so send_websocket_update() and
_send_async() no longer fail silently after epoll is patched out
- Fix PostgreSQL connection exhaustion: CONN_MAX_AGE=0 + explicit
close_old_connections() in stream manager and cleanup watchdog loops
- Fix stream proxy race: register client before the connect-wait loop
so the cleanup watchdog never sees zero clients on a live channel
- Channel list/logo/profile queryset optimisations: conditional DISTINCT,
EXISTS semi-joins for filter-options, channel_count annotation to
eliminate N+1 in LogoSerializer, prefetched memberships in
ChannelProfileSerializer
- JsonResponse for channel ID list and summary endpoints
The production uWSGI configuration (docker/uwsgi.ini) was missing the socket-timeout directive, causing it to default to 4 seconds. When clients (e.g., VLC) buffer VOD streams and temporarily stop reading from the HTTP socket, uWSGI's write operations timeout after 4 seconds, triggering premature stream cleanup and causing VOD streams to disappear from the stats page.
The fix adds socket-timeout = 600 to match the existing http-timeout = 600 value, giving uWSGI sufficient time to wait for clients to resume reading from buffered sockets. This prevents:
- uwsgi_response_write_body_do() TIMEOUT !!! errors in logs
- GeneratorExit exceptions and premature stream cleanup
- VOD streams vanishing from the stats page when clients buffer
The debug config already had socket-timeout = 3600, which is why the issue wasn't observed in debug mode. This fix aligns production behavior with the debug config while maintaining the production-appropriate 10-minute timeout duration.
