Research Summary: Analyzed how two mature media servers handle filesystem watching to identify best practices for fixing Bookhoard's fsnotify reliability issues. Jellyfin (C#/.NET) Approach: - Uses directory-based watching with 64KB internal buffer (16x default) - Smart event merging: consolidates parent/sibling/subpath events - 45-second self-ignore delay for internal changes - Per-library enable/disable via configuration - Weakness: No file stability check, processes immediately Audiobookshelf (Node.js) Approach: - Custom watcher wrapper for cross-platform support - File stability check: polls mtime every 3s until stable (up to 10min timeout!) - 10-second batch delay for processing multiple changes together - renameDetection for move operations - Weakness: Complex custom implementation Phase 0.5 Plan Updates: 1. Added file stability check (Audiobookshelf approach) - New waitForFileStability() function - Polls file mtime every 3 seconds until stable - 60-second timeout prevents infinite waiting - Prevents processing files still being copied/downloaded 2. Added smart event merging (Jellyfin approach) - Updated markDirectoryDirty() with consolidation logic - Replaces child events with parent directory events - Handles sibling consolidation (merges to common parent) - Reduces redundant scans during bulk operations 3. Changed to 10-second batch delay (Audiobookshelf approach) - Changed from 2-second debounce to 10-second batch - Processes all ready directories together - Better balance between responsiveness and efficiency 4. Updated MediaScanner struct - Added fileStability map[string]time.Time field - Added fileStabilityMu sync.RWMutex field 5. Added comprehensive unit tests - TestMarkDirectoryDirty_SmartEventMerging - TestWaitForFileStability_StableFile - TestWaitForFileStability_UnstableFile - TestProcessDirtyDirectories_BatchesScans 6. Added comparison table showing research insights Benefits of Combined Approach: - No event queue overflow (directory-based watching) - Reliable bulk import with file stability checks - Smart event consolidation reduces redundant scans - 10-second batch provides good responsiveness/efficiency balance - Delete detection via 60-second polling safety net - Works on Docker and network mounts Files Changed: - COMPLETE_INFRASTRUCTURE_ENHANCEMENT_PLAN.md (23 lines added) Research Sources: - https://github.com/jellyfin/jellyfin - https://github.com/advplyr/audiobookshelf
