- Enhanced the live proxy to release geventpool DB connections more effectively across various paths.
- Implemented `close_old_connections()` in `stream_ts()`, `generate_stream_url()`, `get_stream_info_for_switch()`, `get_alternate_streams()`, `get_connections_left()`, and the cleanup process in `StreamGenerator`, ensuring that clients do not hold onto pool slots unnecessarily during streaming operations.
- Improved channel teardown process to prevent lingering upstream connections and ensure proper resource cleanup.
- Enhanced client management by implementing checks for ghost clients and ensuring accurate client disconnection handling.
- Updated logging to provide clearer insights during channel initialization and teardown, including handling of unavailable channels.
- Refined stream manager behavior to manage ownership transitions more effectively and prevent blocking during shutdown.
- Improved handling of channel teardown to prevent client reconnect issues across uWSGI workers, ensuring proper resource cleanup and ownership management.
- Added functionality to clear all client entries from Redis for a channel, enhancing client management during shutdown.
- Updated logging and response mechanisms to inform clients of channel availability during teardown,.
- Enhanced stream manager behavior to ensure upstream connections are properly managed during ownership transitions.
- Renamed `_clear_stream_assignment_keys` to `_release_stale_stream_assignment` for clarity and updated its logic to release pool counters.
- Introduced new functions for managing credential slots during profile switches, enhancing the handling of shared connection limits across server groups.
- Removed the `max_streams` field from the `ServerGroup` model and updated related components to reflect this change, simplifying the server group management.
- Updated frontend components to integrate server group management, allowing for dynamic creation and editing of server groups.
- Enhanced error handling in stream URL generation to provide more informative feedback on connection issues.
- Added tests for stale assignment release and credential management during profile switches.
Drop auto-fingerprint migration and restore per-profile selection for live/VOD.
Enforce shared limits on reserve using login-scoped group counters, and add
Server Groups UI for manual account assignment per maintainer feedback (#1137).

- channel_status.py: fold output_format and output_profile_id into the
existing hmget, reducing per-client Redis calls from 3 to 1
- utils.py: collapse 2x and 3x hget per key in scan_iter loops
(get_user_active_connections) to single hmget calls
- views.py: replace 3x hget on channel metadata in the worker-join path
of stream_ts with a single hmget
gevent registers a pthread_atfork handler that never yields. Any
subprocess.Popen/run call in a uWSGI greenlet hangs indefinitely at
fork() before the child process even starts.
- dispatcharr/gevent_patch.py: new; monkey.patch_all() + psycogreen,
loaded via uWSGI import= in all four ini files
- live_proxy/input/manager.py: posix_spawn + _SpawnedProcess; removed
dead forwarder code
- live_proxy/input/http_streamer.py: O_NONBLOCK on relay pipe + EAGAIN
retry (blocking write to a full pipe stalls the gevent hub)
- live_proxy/utils.py: new posix_spawn_proc() helper with O_NONBLOCK
stdin, shared by both output managers
- live_proxy/output/fmp4/manager.py, output/profile/manager.py:
posix_spawn_proc(); _write_all() treats EAGAIN (None) as cooperative
select.select wait instead of fatal error
- core/views.py (stream_view): posix_spawn; fixed pre-existing bug
where return StreamingHttpResponse(...) was indented inside
stream_generator, making the success path always return None
- connect/handlers/script.py: _posix_run() with posix_spawn +
cooperative select reads + non-blocking waitpid; fixes deadlock when
a script integration fires on a uWSGI-context event (client_connect
fires in the live proxy, not Celery)
- 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
