The playlist list was going through SearchItems (not ProxyRequest), so
UpdateSpotifyPlaylistCounts was never called. Now updates counts in both:
- SearchItems when browsing playlists (no search term)
- ProxyRequest for other playlist list requests
This fixes playlists showing 0 tracks when they should show the count
of missing tracks available.
SECURITY FIX: Stop using server API key when clients don't provide auth
Before: If client sent no auth → proxy used server API key → gave them access
After: If client sends no auth → proxy sends no auth → Jellyfin rejects (401)
This ensures:
- Unauthenticated users can't piggyback on server credentials
- All actions are properly attributed to the actual user
- Jellyfin's auth system works as intended
- Server API key only used for internal operations (images, library detection)
Updated test to reflect new behavior: GetJsonAsync without client headers
should NOT add any authentication.
- Log when checking items for Spotify playlists
- Log cache lookups and file cache fallbacks
- Log successful ChildCount updates
- Log when no Spotify playlists found
- Helps diagnose why playlist counts might not be updating correctly
- Log all proxied endpoints to /app/cache/endpoint-usage/endpoints.csv
- CSV format: timestamp, method, path, query string
- Add GET /debug/endpoint-usage?api_key=KEY to view statistics
- Shows top N endpoints by usage count
- Filter by date with since parameter
- Returns total requests, unique endpoints, first/last seen
- Add DELETE /debug/endpoint-usage?api_key=KEY to clear logs
- Thread-safe file appending
- Helps identify which endpoints clients actually use
- Can inform future blocklist/allowlist decisions
- Intercept playlist list responses and update ChildCount for Spotify playlists
- Shows the number of missing tracks found (local + matched external)
- Fixes playlist showing 0 songs when Jellyfin has no local files
- Reads from cache (Redis or file) to get accurate count
- Search forward 12 hours from sync time
- Search backward 24 hours from sync time (was 12 hours)
- Ensures yesterday's file is always found when running at 11 AM after 4 PM sync
- Sync runs daily at 4:15 PM, so 24h backward always catches previous day's file
- List all files in cache directory on startup
- Show expected file paths and actual file existence
- Log each step of cache checking process
- Add phase indicators for forward/backward search
- Show when cache exists and fetch is skipped
- Help diagnose why yesterday's cache files aren't being loaded
- On startup, if no cache exists, fetch immediately regardless of sync window
- Regular background checks still respect sync window timing
- Ensures playlists are populated even if app restarts before sync time
- When favoriting an external track, automatically copy to /kept folder
- Organized as Artist/Album/Track structure
- Includes cover art if available
- Downloads track first if not already cached
- Add KEPT_PATH and CACHE_PATH volumes to docker-compose
- Update .env.example and README with new feature
- Save missing tracks to /app/cache/spotify/*.json files
- 24-hour TTL for file cache
- Fallback to file cache when Redis is empty/restarted
- Controller checks file cache before returning empty playlists
- Ensures playlist data persists across Redis restarts
