None c841cfc8fc Fix #861: Prevent M3U endless downloading caused by Redis lock expiry ... Large M3U downloads that exceed the 300s Redis lock TTL caused Celery Beat to re-queue duplicate tasks, creating overlapping downloads that never complete. Files changed: - core/utils.py: Add TaskLockRenewer class — a daemon thread that periodically renews Redis lock TTL (every 120s) to prevent expiry during long-running tasks. - apps/m3u/tasks.py: Apply TaskLockRenewer to refresh_single_m3u_account and refresh_m3u_groups; add HTTP timeout (30s connect, 60s read) to M3U download (the only download path missing one); stream M3U download to disk instead of accumulating in memory; add Celery task time limits (1 hour hard limit). - apps/epg/tasks.py: Apply TaskLockRenewer to refresh_epg_data and parse_programs_for_tvg_id; add Celery task time limits (30 min / 1 hour). Verified with a throttled test server: locks renewed at T+120s, T+240s, T+360s; 50,000 streams processed with no duplicate tasks.		2026-02-23 00:34:28 -06:00

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
