The 30-day retention window for soft-deleted annotations was a package
const; move it behind the registry so it can be tuned live.
annotations.go:
- AnnotationService gains an optional *database.SettingsRegistry and a
tombstoneTTL() helper. The skip-resurrect checks and the purge cutoff
now call it instead of reading the TombstoneTTL const directly.
- Add ActiveTombstoneTTL() so callers outside the sync package can
compute cutoffs consistently with the service.
- The package-level TombstoneTTL const is retained as the fallback for
tests / unwired code paths.
kobo.go, koreader.go:
- The per-book tombstone sweep cutoff now uses
h.annotationSvc.ActiveTombstoneTTL() instead of the wsync.TombstoneTTL
const, so both the service and the handlers honor the configured TTL.
Complete the annotation sync pipeline across all ingest and serve paths.
Previously, annotations sent inline with KOReader progress pushes were
silently discarded, and no annotations were ever served back to devices.
INGEST (device → server):
KOReader (koreader.go):
- Add processBookAnnotations helper that processes inline highlights,
notes, and bookmarks from every progress push (immediate + checkpoint)
- Highlights get CRE→CFI position conversion before SaveHighlight
- KOReader 'notes' (text + notes) stored as highlights with NoteText
to ensure correct round-trip classification
- Bookmarks routed through SaveBookmark with device sync data
- Called from both updateProgressForBook and handleCheckpointSync
Kobo (kobo.go):
- Markup handler: annotations and bookmarks route through
AnnotationService (SaveHighlight/SaveBookmark)
- Bookmark handler: same routing with device sync data
- SyncFromServer handler: same routing
- All handlers fall back to direct DB calls when annotationSvc == nil
Web reader (media.go):
- CreateMediaHighlight → SaveHighlight (Source="web", ModifiedAt=now)
- CreateMediaNote → SaveNote (Source="web")
- DeleteMediaHighlight → TombstoneHighlightByID
- DeleteMediaNote → TombstoneNoteByID (was hard delete, now tombstone)
- All fall back to old behavior when annotationSvc == nil
SERVE (server → device):
KOReader GetMetadata (koreader.go):
- Query and serve bookmarks from media_bookmarks table (was missing)
- Serve deleted_highlights and deleted_bookmarks arrays containing
device_sync_data + dedup_key for client-side deletion
- Highlights/notes already served with reverse CFI conversion
Kobo Markup handler (kobo.go):
- Track processed books during sync
- Query tombstones per book, extract bookmark_id from device_sync_data
- Return DeletedAnnotations array in KoboSyncStatus response
Conflict resolution (conflicts.go):
- Enable annotation conflict types in ResolveConflict handler
- Add applyAnnotationResolution dispatching to:
applyHighlightResolution / applyBookmarkResolution / applyNoteResolution
- Each looks up by dedup_key and applies winner's fields
- Allow manual override of auto_resolved conflicts
(changed check from != "unresolved" to == "user_resolved")
Infrastructure:
- AnnotationService field + SetAnnotationService in router Config
- Inject AnnotationService into KOReader, Kobo, Media handlers
- Start tombstone purger goroutine in main.go (24h interval)
- Test helpers: construct AnnotationService in test setup
The push path (koreader→server) was already updated to omit epubcfi
for paging documents, and SaveProgress derives percentage from
page/total_pages for fixed formats. However, the pull path
(server→koreader) still returned any stored epubcfi and attempted
CFI→XPointer conversion, and SaveProgress preserved stale CFI values
written by the web reader (which generates fake CFIs via
CFI.fake.fromIndex for every comic/PDF page).
These fake CFI strings lingered in the database and koreader's pull
path picked them up over progress.page, causing tonumber("epubcfi(...)")
→ nil → GotoPage(nil) → crash when the user confirmed the sync prompt.
Changes:
- GetMetadata (koreader.go): for fixed_layout/comic_archive formats,
skip returning epubcfi and skip the CFI→CRE XPointer conversion.
Reflowable documents are byte-for-byte unchanged.
- SaveProgress (progress.go): for fixed formats, explicitly clear
epubcfi and character_offset on every save so stale values from
prior web-reader sessions are cleaned up over time.
The CRE->CFI converter works by text search / character-offset mapping
across the EPUB spine. Image-based fixed content (fixed-layout comic
EPUBs, PDFs, comic archives) has no extractable text, so the conversion
can never succeed and only wastes time parsing content docs while
logging a failed percentage-precision result.
Guard the conversion in the KOReader progress handler: when the matched
media item's FormatGroup is fixed_layout or comic_archive, skip
ConvertCREToStandard entirely. The incoming xpointer is left as-is so
KOReader<->KOReader restore via GotoXPointer still works; the web reader
restores by page index (the canonical locator for these formats).
This covers fixed-layout comic EPUBs in particular: KOReader routes all
EPUBs through CREngine (has_pages == false), so they send a real
xpointer that passes IsCREXPointer and would otherwise trigger the
doomed text extraction. Reflowable EPUBs (format_group == reflowable)
still run the conversion exactly as before.
Forward (push): When KOReader pushes a CREngine XPointer, convert it
to standard epubcfi before storing. Uses CFIConverter.ConvertCREToStandard
with context_text for text search fallback.
Reverse (pull): When KOReader pulls progress, convert stored standard
epubcfi back to CREngine XPointer via CFIConverter.ConvertStandardToCRE.
Returns as koreader_xpointer field in GetMetadata response.
Other changes:
- updateProgressForBook: pass context_text to SaveProgress
- enqueueProgressForBook: pass context_text to queue
- KOReaderProgressData: add KoreaderXPointer field
- New convertCFIToXPointer helper method
- Wire libraryService in main.go for EPUB path resolution
All four progress write paths now delegate to ProgressService.SaveProgress:
- MediaHandler: UpdateMediaReadingProgress uses ProgressService for web
saves with richer request body (reading_mode, zoom_level, scroll). GET
now uses GetUniversalProgress query that JOINs media_items for
format_group, total_characters, chapter_count.
- KOReaderHandler: updateProgressForBook delegates to ProgressService.
Fixed device ID bug (was using userID, now uses deviceID). Removed
duplicate UpdateDeviceLastSync with zero UUID. Added pgtype helper
functions (textPtrToPgText, intPtrToPgInt4, int64PtrToPgInt8).
- KoboHandler: all four progress write points (Markup ReadingSync, Markup
last-read-place, AnalyticsGettests, SyncFromServer) delegate to
ProgressService. Fixed empty epubcfi string now correctly set to
Valid: false. SyncFromServer preserves last_sync_source=bookhoard
and Broadcast: false.
- QueueProcessor: syncProgress delegates to ProgressService.
- main.go: creates ProgressService after ConnectionManager, injects via
SetProgressService() on all handlers and queue processor.
Handler tests cover pgtype conversion helpers (textPtrToPgText, etc.)
and device icon mapping.
Go's new() builtin takes a type and allocates a zero value — it cannot
wrap an expression. All instances of new(someExpression) were compile
errors. Replace each with a local variable assignment and address-of
operator.
Affected files:
- handlers/koreader.go: progress field pointers (Chapter, Page, etc.)
- handlers/kobo.go: pagesRemaining pointer
- handlers/queue.go: uuidPtrToString and timestamptzPtrToString helpers
- router/reader.go: bookmark pageNumber and chapterNumber pointers
- services/media_scanner.go: validation error message pointers
- services/worker.go: StartedAt and CompletedAt timestamps
- sync/offline.go: GetDeviceStatus return pointer
- tests/device_test.go: SyncEnabled and SyncFrequencyMinutes pointers
Remove redundant type conversions that Go 1.26 makes unnecessary or that
were already no-ops:
- uuid.UUID(x.Bytes) → x.Bytes (uuid.UUID is [16]byte, same as pgtype UUID Bytes)
- pgtype.UUID{Bytes: [16]byte(u), Valid: true} → pgtype.UUID{Bytes: u, Valid: true}
- (*time.Time)(&x.Time) → &x.Time
- json.RawMessage(x) → x where x is already []byte
- []byte(stringVal) → stringVal where []byte is expected
- int()/int64()/byte() casts on values already of the target type
- Decompressor(fn) → fn (type is identical)
Handle previously ignored error returns:
- collections.go: check json.Unmarshal error in GetCollection
- conversion_service.go: check fileSize.Scan() error
- app_test.go: check app.Shutdown() error in benchmark
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.
