- Added a new function `_is_uwsgi_worker` to accurately identify when the application is running within a uWSGI worker.
- Updated `get_process_role` to label processes as "uwsgi" based on the new function or command-line arguments, improving process role accuracy.
- Expanded unit tests to cover various scenarios for uWSGI role detection, ensuring robust validation of the new logic.
- 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
Mixing threading and gevent concurrency models causes uWSGI workers to
crash with segmentation faults, particularly on ARM64/Python 3.13.
The production uwsgi.ini was already correct (gevent without threads).
This fixes the dev and debug configs to match.
