Replace direct equality checks (err != pgx.ErrNoRows) with the idiomatic
errors.Is(err, pgx.ErrNoRows) pattern. This is the recommended Go practice
for error comparison as it correctly handles wrapped errors from error
chains, making the code more robust against future refactoring that might
wrap errors with fmt.Errorf and %w.
Simplify pointer creation across kobo, koreader, and queue handlers by
replacing the two-step pattern (assign to local, then take address) with
inline new() calls. This reduces verbosity without changing behavior:
Before:
remaining := int(a - b)
pagesRemaining = &remaining
After:
pagesRemaining = new(int(a - b))
Covers page calculations, chapter/progress fields, UUID formatting,
and timestamp string conversions.
Fix 1 - File modification time for created_at:
- Get file.ModTime() in processMediaFile and pass to CreateMediaItem
- Modified SQL INSERT to include created_at column
Fix 2 - Force rescan UPDATE instead of DELETE+INSERT:
- Changed force rescan logic to call updateMediaItem instead of delete + create
- Preserves created_at timestamp on force rescan
Fix 3 - GetMediaItemByFilePath filters by library_id:
- Added library_id to WHERE clause in SQL query
- Created GetMediaItemByFilePathAnyLibrary for cross-library lookups (KOReader)
- Added SetLibraryID method to MediaScanner
- Updated handler to call SetLibraryID for watch mode
Fix 4 - File deletion handling with persistent logging:
- Added fsnotify.Remove handler in WatchChanges
- Added orphan cleanup in ScanFolders after scan completes
- Created scanner_logger.go with daily log rotation (7 days)
- Logs to /app/logs/scanner-deletes-YYYY-MM-DD.log and scanner-errors-YYYY-MM-DD.log
- Individual deletes with enhanced safety logging
Note: Integration tests can now safely scan /app/uploads because
GetMediaItemByFilePath now filters by library_id, preventing
cross-library interference.
Implement conflict detection for concurrent reading progress updates from different devices. Adds conflict management endpoints for listing, viewing, and resolving conflicts.
- Add ConflictHandler with CRUD endpoints for conflict management
- Implement automatic conflict detection in KOReader progress updates
- Add WebSocket broadcast for real-time conflict notifications
- Add database query for listing user conflicts by status
- Add integration tests and Bruno API test collection
Add WebSocket broadcast to KOReader progress sync:
- Integrate ConnectionManager into KOReaderHandler
- Broadcast progress updates on successful sync
- Include source device information (model, type)
- Real-time updates to all connected clients
When KOReader devices sync reading progress, all connected
WebSocket clients (web browsers, mobile apps, other devices)
receive instant updates.
- Create SyncProgress for bidirectional progress synchronization
- Create GetMetadata for book progress and annotation retrieval
- Create GetLibrary for user library sync
- Create SyncBookmarks for annotation management
- Support device matching by UUID, file path, or title/author
- Implement immediate and checkpoint sync modes
- Handle bookmarks, highlights, and notes synchronization
- Part of Phase 3 KOReader Integration implementation
