Frontend:
- RecordingDetailsModal: fix ReferenceError crash (editing state used before declaration in useMemo — TDZ in production bundles broke all tile clicks)
- RecordingDetailsModal: fix focus-stealing on description edit by calling Movie()/Series() as plain functions instead of <Movie />/<Series />(inline component refs change every render, causing unmount/remount)
- RecordingDetailsModal: suppress sub_title in modal title after custom save
- ErrorBoundary: log caught errors and show message for easier debugging
- guideUtils: filter terminal recordings from mapRecordingsByProgramId so Guide red dots clear after recording finishes or rule is deleted
- RecordingDetailsModalUtils.test: add missing end_time to test fixtures (filterByUpcoming now uses end_time instead of start_time)
Backend:
- tasks.py: output file collision avoidance (check .mkv/.ts before writing)
- tasks.py: pre-restart TS segment concatenation (direct concat→MKV remux)
- tasks.py: recovery pipeline — recover crashed "recording" status, remux expired recordings, revoke stale tasks, deterministic task IDs, early lock release, 10-min lock TTL for large remux operations
- tasks.py: poster resolver skips external API when title matches channel name
- celery.py: trigger recover_recordings_on_startup via worker_ready signal
Tests:
- Renamed test_dvr_fixes.py → test_recording_pipeline.py (clarity)
- Renamed test_dvr_retry.py → test_db_retry.py (clarity), fixed mock paths for close_old_connections (resolved 3 test failures), replaced synthetic test
- test_recording_stop_cancel: replaced brittle time.sleep(0.5) with deterministic thread-capture pattern
Backend:
- Add terminal status guard to stop() endpoint -prevents overwriting completed/interrupted/failed with "stopped" (returns 409 Conflict)
- Include currently-airing programs in series rule evaluation by filtering on end_time instead of start_time
- Clean up future recordings when deleting a series rule while preserving previously recorded episodes
- Add logo proxy negative cache to prevent repeated requests to unreachable hosts from blocking Daphne workers
- Add URL validation with HEAD-then-GET fallback and per-worker cache
- Add EPG time-slot matching (80% overlap threshold) to enrich manual recordings with program metadata
- Add multi-source poster resolution pipeline (EPG, VOD, TMDB, OMDb, TVMaze, iTunes) with URL validation at each stage
- Add editable recording metadata endpoint with user_edited flag to prevent EPG auto-overwrite
- Add refresh-artwork endpoint to re-run poster resolution on demand
- Batch-fetch PeriodicTask names in schedule_upcoming to avoid N+1
Frontend:
- Fix series modal showing only one episode — preserve _group_count from categorized prop when merging with store version so the episode list renders correctly
- Fix recording card button positioning — use flex column layout with marginTop auto so buttons align at the bottom regardless of content
- Add delete fallback in RecurringRuleModal for orphaned recordings from deleted rules
- Use end_time filter in upcoming episodes list to include currently-airing episodes
- Add inline metadata editing (title/description) in details modal
- Add refresh artwork button in details modal
- Replace hardcoded /logo.png fallbacks with imported default logo
- Add React.memo with custom comparator to RecordingCard
Tests:
- Add 21 EPG time-slot matching tests (overlap threshold, edge cases)
- Add 16 recording metadata tests (validation, artwork, logo cache)
- Add 17 URL validation tests (HEAD/GET fallback, caching, eviction)
Add exponential backoff retry (_db_retry helper) for transient DB errors during final metadata save, startup recovery, and initial TS proxy
connection. Add FFmpeg remux retry for transient I/O errors. Retry same proxy base before falling back to next candidate on initial connection failure.
Fix DVR card logos not displaying: channel summary API returns logo_id (integer) but frontend expected a nested logo object with cache_url.
Add getChannelLogoUrl() helper that handles both data shapes. Backend artwork prefetch and run_recording now fall back to the channel's own logo when no show-specific artwork is found, ensuring poster_logo_id is always populated.
Prevent incorrect artwork by skipping external API searches (TVMaze, iTunes) when no program title is available - channel names like
"USA A&E SD*" returned unrelated results from fuzzy matching.
Add 13 tests for retry logic (test_dvr_retry.py)
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.
