None f28530a47b fix(dvr): add recording extend, fix cross-recording interference, artwork race, and keepalive gaps ... File changes: Backend apps/channels/api_views.py — Added extend() action that uses queryset .update() to bypass signals, letting the running task pick up the new end_time via polling. Moved WS recording_stopped notification to synchronous (before HTTP response). Refactored destroy() to delete DB row first, send WS event immediately, defer cleanup to background thread. apps/channels/signals.py — Added pre_save guard to skip task revocation when status is "recording". Added post_save reentrancy guard to skip artwork prefetch for internal field-only saves (custom_properties, task_id, end_time). apps/channels/tasks.py — Added 2-second polling loop in streaming that checks for stop, deletion, and extended end_time. Added refresh_from_db() + merge before metadata save to prevent overwriting concurrent artwork prefetch. Replaced inline PeriodicTask cleanup with revoke_task()/_dvr_task_name(). Consolidated redundant DB queries in error path. Fixed TOCTOU os.path.exists + os.remove. Preserved "stopped" status in final-status logic instead of overwriting with "completed". core/utils.py — Made send_websocket_update gevent-safe by detecting monkey-patching and offloading async_to_sync to gevent's native threadpool, fixing the event loop deadlock that caused cross-recording interference. apps/proxy/ts_proxy/client_manager.py — Moved _trigger_stats_update to a background thread so remove_client() returns immediately. apps/proxy/ts_proxy/stream_generator.py — Added Redis-based health check for non-owner workers in _should_send_keepalive(), so keepalives fire correctly even when stream_manager is None. Frontend frontend/src/WebSocket.jsx — Added 400ms debounced scheduleRecordingFetch() replacing all inline fetchRecordings() calls. Added recording_extended and recording_updated event handlers. recording_cancelled now does surgical removeRecording() by ID when available. frontend/src/api.js — Added extendRecording(id, extraMinutes). frontend/src/components/cards/RecordingCard.jsx — Added Extend menu (+15m/+30m/+1h) for in-progress recordings. Widened Comskip button to stopped/interrupted statuses. frontend/src/components/forms/ProgramRecordingModal.jsx — Removed manual fetchRecordings() calls, relying on WS-driven debounced refresh. frontend/src/components/forms/RecordingDetailsModal.jsx — Added stopped to playable statuses. Widened Comskip button. Removed manual fetchRecordings(). frontend/src/components/forms/RecurringRuleModal.jsx — Removed all manual fetchRecordings() calls, relying on WS events. frontend/src/pages/Guide.jsx — Removed isLoading subscription that caused loading flash on debounced refresh. Removed manual fetchRecordings() after saving a series rule. frontend/src/store/channels.jsx — Stripped isLoading/error state from fetchRecordings to prevent full-page loading indicators. Added no-op guards in removeRecording. frontend/src/utils/cards/RecordingCardUtils.js — Added extendRecordingById wrapper. Tests apps/channels/tests/test_recording_extend.py (new) — 14 tests: extend endpoint validation, stacked extensions, signal bypass, pre_save guard behavior. apps/channels/tests/test_recording_stop_cancel.py (new) — 18 tests: stop endpoint, DVR client teardown, cancel was_in_progress flag, run_recording race guards, signal reentrancy guards. apps/channels/tests/test_ts_proxy_keepalive.py (new) — 21 tests: keepalive owner/non-owner logic, stats update error handling, client removal non-blocking, timing invariants. apps/channels/tests/test_recording_scheduling.py — Updated mock assertion to match new _stop_dvr_clients call signature. Summary: Adds an Extend action for in-progress recordings that bypasses Django signals and lets the running task dynamically pick up the new end_time via its 2-second DB polling loop. Fixes cross-recording interference caused by send_websocket_update deadlocking the gevent event loop. Fixes an artwork race condition where run_recording overwrote concurrent prefetch data. Adds Redis-based keepalive health checks for non-owner workers to prevent DVR read timeouts during source transitions. Replaces manual fetchRecordings() calls throughout the frontend with a debounced WS-driven refresh. 53 new tests.		2026-03-04 10:21:02 -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
