- Replace per-entry ProgramData DB query with single batch fetch
- Pass pre-loaded EPGData objects to find_current_program_for_tvg_id
to avoid redundant select_related re-fetch
- Delete Redis programme index before XMLTV download so stale byte
offsets are never used during the refresh window
When selecting an EPG channel in the channel form, if that EPG entry's
programs had never been parsed, the preview showed "No current program".
This was because parse_programs_for_tvg_id requires a linked channel.
- Add force parameter to parse_programs_for_tvg_id to bypass channel check
- Auto-trigger parsing from current-programs API when no programs exist
- Check Redis task lock to prevent duplicate parse tasks from concurrent requests
- Frontend retries up to 3 times with 10s delay to pick up parsed results
- Skip parsing for dummy EPG sources
- Extract ProgramPreview component from duplicated code in Channel.jsx
and StreamConnectionCard.jsx (~80+ lines each)
- Fix watch('epg_data_id') called directly in useEffect dependency array,
which could cause infinite re-renders
- Add request cancellation for rapid EPG selection changes in channel form
- Remove unused imports (Radio, Progress, ChevronDown, ChevronRight)
- Extended CurrentProgramsAPIView to accept epg_data_ids parameter
- Added getCurrentProgramForEpg() API method in frontend
- Added UI in Channel form showing current program with tooltip
- Shows loading state, no program state, and program details
- Includes expandable description, progress bar with elapsed/remaining time
- Matches stats page 'Now Playing' feature behavior
- Use 'youtube_trailer' key (matching api_views.py and advanced refresh)
instead of orphaned 'trailer' key that was never consumed.
- On basic sync, only write director/actors/release_date to
custom_properties when the field is currently empty. This prevents
basic sync from overwriting richer data previously stored by
refresh_movie_advanced_data, while still populating those fields for
movies that have never had an advanced refresh run.
Tested: logic verified against all three scenarios (preserve existing
rich data, populate empty fields, youtube_trailer key propagation).
