Introduces `asin` and `isbn` fields to the PlexLibrary schema and database, with migration and indexing for fast lookups. Updates scan and recently-added processors to persist ASIN/ISBN from both Plex and Audiobookshelf backends. Enhances matching logic to prioritize exact ASIN matches using the new fields, improving match accuracy for Audiobookshelf users. Also includes minor improvements: fixes cover art handling for cached thumbnails, adds download URL validation in Prowlarr and qBittorrent integrations, and updates documentation to reflect these changes.
Root cause: Singleton caching issue
The qBittorrent service uses a singleton pattern with a configLoaded flag.
Once initialized, it NEVER re-reads the database config, even when the
user changes settings via the admin settings page.
Flow showing the bug:
1. Wizard saves download_dir to database ✓
2. First torrent: service reads config, creates singleton, sets configLoaded=true ✓
3. User changes download_dir in settings page ✓ (database updated)
4. Next torrent: getQBittorrentService() returns CACHED singleton ✗
5. Cached singleton has OLD download_dir value in this.defaultSavePath ✗
6. Category check shows "already has correct save path: /old/path" ✗
7. Download goes to wrong location ✗
The singleton check (line 745):
if (!qbittorrentService || !configLoaded) {
// Only runs if service doesn't exist or config failed
}
Once both exist, this block is SKIPPED forever!
Fix:
1. Added invalidateQBittorrentService() function
- Resets qbittorrentService = null
- Resets configLoaded = false
- Forces reload from database on next use
2. Call invalidation from settings APIs:
- After updating paths (download_dir, media_dir)
- After updating download client (URL, credentials)
3. Next torrent addition:
- getQBittorrentService() sees null singleton
- Re-reads config from database
- Creates new service with current download_dir
- Category updated with correct path
Benefits:
- Settings changes take effect immediately
- No app restart needed
- Category save path always matches current config
- Download client credentials always current
Updated documentation to explain singleton invalidation pattern.
Previously, when a user changed the download_dir setting after initial
setup, the qBittorrent category "readmeabook" would retain the old save
path. This could cause torrents to download to the wrong location,
depending on qBittorrent's Automatic Torrent Management (ATM) settings.
Root cause:
- ensureCategory() only created the category if it didn't exist
- createCategory API is idempotent but doesn't update existing categories
- If download_dir changed from /downloads to /downloads/RMAB, category
would still have savePath=/downloads
qBittorrent behavior:
- If ATM enabled: category savePath overrides per-torrent savepath
- If ATM disabled: per-torrent savepath takes precedence
Fix:
- ensureCategory() now calls both createCategory AND editCategory
- createCategory: ensures category exists (idempotent)
- editCategory: updates save path to match current download_dir config
- This guarantees category path is always synced with database config
Benefits:
- Users can change download_dir setting and it takes effect immediately
- Works regardless of ATM settings in qBittorrent
- No manual qBittorrent category management needed
Updated documentation/phase3/qbittorrent.md to explain category
management and save path synchronization.
Previously, files were always being copied to /media/audiobooks regardless
of the configured media directory in settings. This was caused by:
1. FileOrganizer singleton reading from MEDIA_DIR env var (never set)
instead of database config 'media_dir'
2. Hardcoded /media/audiobooks fallback being used when env var not found
3. Three locations passing hardcoded paths to addOrganizeJob (unused)
Changes:
- Modified getFileOrganizer() to read media_dir from database config
- Made targetPath parameter optional in addOrganizeJob (not used by processor)
- Removed hardcoded /media/audiobooks paths from all addOrganizeJob calls
- Updated organize-files processor to await getFileOrganizer()
- Updated documentation to reflect configuration behavior
Files now correctly copy to the directory configured in setup wizard or
settings page, with /media/audiobooks only as fallback if not configured.
Fixes: User-reported issue where configured media directory was ignored
**Problem:** Prowlarr searches were querying ALL indexers instead of only
the ones enabled in user settings, causing torrents to be selected from
disabled/untrusted indexers.
**Root Cause:** The prowlarr.search() method didn't filter by indexer IDs,
and callers weren't passing enabled indexer IDs to the search.
**Changes:**
1. Added indexerIds parameter to SearchFilters interface
2. Updated prowlarr.service.ts search() to filter by indexerIds
3. Updated search-indexers.processor.ts to fetch and pass enabled indexer IDs
4. Updated interactive-search route to fetch and pass enabled indexer IDs
5. Added validation: search fails if no indexers are configured/enabled
6. Updated documentation to reflect indexer filtering behavior
**Impact:**
- Manual search: Only searches enabled indexers
- Interactive search: Only searches enabled indexers
- RSS monitoring: Already correctly filtered (no changes needed)
**Testing:** TypeScript type checking passed with no errors
