- Added support for customizable title and description matching modes in series rules.
- Implemented a preview feature for series rules to show matching upcoming programs.
- Created a new SeriesRuleEditorModal for editing series rules with improved UI.
- Refactored query parsing logic into reusable functions for better maintainability.
- Updated API to handle new parameters for series rule creation and evaluation.
- Enhanced the ProgramRecordingModal and SeriesRecordingModal to integrate the new rule editor.
- Added pagination for program search results in the API.
- Scope regex previews to the M3U account being edited
- Empty-state message extended from "No streams in this group yet." to "No streams in this group yet. Run an M3U refresh first to populate streams."
Layered on top of the prior perf commits, removes additional per-row queries
Channel list (apps/channels): add auto_created_by to select_related so ChannelSerializer.get_auto_created_by_name does not fire one SELECT per row. Replace instance.streams.all().order_by(channelstream__order) in to_representation with a read off the prefetched channelstream_set.
M3U account list (apps/m3u): prefetch_related "filters" on the viewset queryset and sort filters in Python over the prefetch in M3UAccountSerializer.get_filters.
Frontend (EditableCell.jsx): align the saveValue useCallback dependency from [row.original.id] to [row.original] in the Number, Group, EPG, and Logo cells, matching the pattern applied to the Text cell.
The previous name suggested "hidden from a specific user account" rather than "hidden from downstream client output", which was the actual
behavior. The new name is unambiguous and matches the help_text language ("Exclude this channel from downstream client output").
Mechanical rename across the migration, model, serializer, signals, sync logic, output endpoints, frontend forms / tables / utils, tests, and CHANGELOG. 77 occurrences across 20 files.
No behavior change.
Per-field channel overrides for auto-synced channels, hide-from-output flag, range-bounded auto-numbering with re-pack, multi-stream channel safety, multi-provider shared-range merging, and an across-the-board move from per-row sync writes to bulk operations.

See CHANGELOG.md for the full commit log
- Replace ProgramData.id-based dedup with stable (tvg_id, start_time, end_time) key from Recording.custom_properties.program. ProgramData IDs change on every EPG refresh; the old dedup always passed after refresh, creating duplicates.
- Fix secondary timeslot guard to compare original program times (stored in custom_properties) instead of offset-adjusted Recording times. With DVR pre/post offsets configured, the old guard never matched.
- Add acquire_task_lock/release_task_lock to serialize concurrent evaluate_series_rules calls. Multiple EPG source refreshes firing evaluate_series_rules.delay() simultaneously raced to create duplicate recordings.
- Rewrite ghost client tests to call real ChannelStatus and ClientManager code paths instead of reimplementing detection logic in test helpers
- Rewrite initializing state tests to invoke StreamManager.run() so the real finally block executes under test
- Replace hardcoded state list tests with assertions against ChannelState.PRE_ACTIVE frozenset
- Add missing SOURCE_BITRATE and FFMPEG_BITRATE constants to ChannelMetadataField (referenced by channel_status.py but never defined, causing AttributeError on detailed stats)
- Add MAX_KEEPALIVE_DURATION = 300s to TSConfig
- Track keepalive_start_time in _stream_data_generator; disconnect after cap is exceeded with a warning log
- Reset timer on real data so independent stalls don't accumulate
- Fix pre-existing test helper missing throttle attributes in NonOwnerWorkerKeepaliveTests
- Write ERROR via ownership check OR state guard fallback when ownership TTL expired during retries
- Add INITIALIZING to cleanup task grace period monitoring
- Validate client SET entries against metadata hashes in orphaned channel cleanup; remove ghosts and clean up when no real clients remain
- Stats page self-heals by removing ghost SET entries on read
- Extract remove_ghost_clients() helper to ClientManager
- Add ChannelState.PRE_ACTIVE constant
- Fix 6 pre-existing NonOwnerWorkerKeepalive test failures
- Add search, channel, and status filter controls to DVR page (matching Guide/VODs pattern)
- Fix post_save signal to schedule recordings for currently-playing programs immediately instead of skipping them
- Remove duplicate evaluate_series_rules.delay() call from series rule creation endpoint to prevent race condition that created two recordings for the same program
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
- Idempotency guard: fail closed on DB errors instead of proceeding, preventing duplicate tasks from overwriting valid recordings (#641)
- Remux sanity checks: reject MKV output that is <50% of a previous MKV (duplicate-task overwrite) or <10% of the source TS (corrupt first attempt); preserve .ts for manual recovery on all failure paths (#619)
- Recurring rule timezone fix: use user's configured timezone for date window calculation instead of UTC, fixing silent recording loss for users in UTC-negative timezones after 4pm local time (#1042)
- Include .ts path in final remux failure log for easier recovery
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)
