PFalko 8bd38ad71c Fix stream ownership bugs causing streams to die after 30-200s ... Three interrelated bugs cause TS proxy streams to terminate prematurely in multi-worker uWSGI deployments: 1. Double ProxyServer instantiation: ProxyConfig.ready() in apps/proxy/apps.py calls TSProxyServer() directly, bypassing get_instance(). The subsequent TSProxyConfig.ready() call to get_instance() creates a second instance. Each instance starts its own cleanup thread, but only one holds channel data — the orphaned cleanup thread cannot extend ownership. 2. Redis flushdb() on every client init: RedisClient.get_client() in core/utils.py calls flushdb() whenever a new connection is created. Celery autoscale workers spawning mid-stream nuke all Redis keys including ownership, client records, and channel metadata. 3. No recovery from expired ownership: get_channel_owner() has a TOCTOU bug (two separate GET calls in a lambda). extend_ownership() silently fails when keys expire. Non-owner cleanup unconditionally kills streams even when the worker holds the stream_manager. Fixes: - Use TSProxyServer.get_instance() in ProxyConfig.ready() - Remove flushdb() from Redis client initialization - Use sentinel pattern for gevent-safe singleton (threading.Lock does not work with gevent greenlets) - Single GET in get_channel_owner() to avoid TOCTOU race - Re-acquire expired ownership keys in extend_ownership() - Attempt re-acquisition before cleanup in non-owner path Relates to #992, #980		2026-02-27 16:40:28 +01:00

apps.py	Enhancement: Refactored app initialization to prevent redundant execution across multiple worker processes. Created dispatcharr.app_initialization utility module with should_skip_initialization() function that prevents custom initialization tasks (backup scheduler sync, developer notifications sync) from running during management commands, in worker processes, or in development servers. This significantly reduces startup overhead in multi-worker deployments (e.g., uWSGI with 10 workers now syncs the scheduler once instead of 10 times). Applied to both CoreConfig and BackupsConfig apps.	2026-02-05 13:48:01 -06:00
