Debounce embedding/tagging completion notifications per folder (6s window)
so rapid file additions from downloaders fire one notification instead of
one per file. Add per-folder mute via the sidebar context menu and a global
pause toggle in Settings > General, both persisted across restarts.
Delete thumbnails alongside DB rows in all three removal paths (watcher
detect, delete-from-disk command, remove-folder command) so orphans no
longer accumulate passively.
Intercept RenameMode::Both watcher events and handle them as in-place
path updates: renames the thumbnail file to the new hash and updates the
DB row without touching the embedding, avoiding a full rebuild on move.
Falls back to thumbnail regeneration if the file rename fails.
Scans the thumbnails directory and cross-references against thumbnail_path
values in the images table, deleting any files not linked to an indexed image.
Surfaces count and reclaimable MB in the General section alongside the
existing Compact database card.
Adds get_database_info and vacuum_database Tauri commands. The General
section now shows current DB size and reclaimable space on load, with a
Compact now button that runs PRAGMA wal_checkpoint(FULL) + VACUUM and
reports how many MB were freed. Button disables automatically when the
database is already compact (< 0.5 MB reclaimable).
- folder_ids: use snake_case in both set_tagging_queue_folder_ids invoke
calls (toggleTaggingQueueFolder and setTaggingQueueFolderIds) to match
the Rust SetTaggingQueueFolderIdsParams serde field name
- threshold save error: route setTaggerThreshold() catch to
setTaggerThresholdError instead of setTaggerQueueStatus so the error
surfaces next to the threshold input, not the queue targets card
- Remove Workers section (read-only status, belongs in background tasks panel)
- Remove Captioning coming-soon placeholder
- Add General section with Open data folder button (tauri-plugin-opener)
- Persist queue scope and folder selection across sessions via settings files
- Show inline validation errors on threshold/batch size inputs instead of silent revert
- Fix acceleration save errors appearing in wrong card
- Disable folder selection controls when target scope is All media
Merges feat/watchdog-exif-timeline into main.
- Adaptive filesystem watchdog: switches between inotify/ReadDirectoryChanges
and polling with zero CPU when idle; watcher events update sidebar counts live
- EXIF taken_at: extracted at index time and stored as a sortable column;
new taken_asc/taken_desc sort orders; migration is safe on existing DBs
- Timeline view: virtualised month-grouped grid (react-virtual v3), reuses
ImageTile/ContextMenu, Calendar icon in Sidebar, defaults to taken_asc sort
- Bug fixes: startup migration panic on existing DBs without taken_at column,
"Unknown Date" grouping due to null created_at fallback, watcher not updating
folder image counts, cols overflow in Timeline grid
- Fix cols overflow: use (containerWidth - GAP) formula so the grid
never exceeds the container width
- Explicitly pin "unknown" date keys to the end of the sort rather than
relying on alphabetical accident ("u" > digits)
- Guard buildLabel against non-YYYY-MM keys with finite/range checks
and an isNaN fallback to "Unknown Date"
- Clear similarSourceFolderId, similarFolderId, and similarCrop when
switching to the timeline view so all similar-state is consistently
reset
db.rs:
- Move idx_images_taken_at creation to after ensure_column so it never
runs against a schema where taken_at doesn't exist yet; this was causing
a startup panic on any DB that predates Phase 1
- COALESCE(taken_at, created_at) → COALESCE(taken_at, modified_at) since
created_at is never populated (modified_at is always set)
- Remove dead is_tagging_job_cancelled function (superseded by
is_tagging_job_processing) and unused thumbnail_path from ImagePathRecord
indexer.rs:
- Watcher create path now calls update_folder_count after commit_batch and
emits folder-counts-changed so the sidebar count stays in sync; the
notification is only emitted when the DB write actually succeeds
store.ts / Timeline.tsx:
- compareImages taken_asc/taken_desc: fall back to modified_at not
created_at (created_at is always null)
- Timeline groupImages: same fallback fix so images group by month
correctly for libraries not yet re-indexed for EXIF
- subscribeToProgress: listen for folder-counts-changed and call
loadFolders() to keep the sidebar image count live
- New Timeline view groups all media by YYYY-MM using taken_at ?? created_at
- @tanstack/react-virtual (group-level virtualiser) keeps scroll smooth on
large libraries; estimateSize is exact so no measureElement needed
- ResizeObserver tracks container width; virtualizer.measure() is called on
cols change to prevent stale position cache after window resize
- setView("timeline") in store auto-sets sort:"taken_asc", resets images,
and triggers a fresh load
- Calendar nav item added to Sidebar between Explore and Duplicates
- ContextMenu and ImageTile exported from Gallery for reuse in Timeline
Monitors all registered folders using OS-native events (ReadDirectoryChangesW
on Windows) so new, modified, and deleted files are reflected in the gallery
automatically without manual reindexing.
Key design points:
- Adaptive blocking: recv() when no events pending (zero CPU), switches to
recv_timeout(earliest_deadline) only when debounce timers are running — wakes
exactly when the soonest event is ready, no busy-polling
- 500 ms per-path debounce coalesces rapid OS event bursts into one action
- Change detection preserved: build_record skips upsert if file_size + mtime
unchanged, preventing spurious thumbnail/embedding re-queues and avoiding
clobbering of existing metadata like thumbnail_path
- Access events (reads) filtered out; only Create/Modify/Remove trigger work
- Deletion path: emits watcher-deleted event with image IDs; frontend removes
those images from state and clears selectedImage if it was deleted
WatcherHandle stored in app state; add_folder / remove_folder / update_folder_path
commands keep the watched path set in sync with the DB.
Adds EXIF date extraction during indexing so photos can be sorted by when
they were actually taken, not just when the file was modified on disk.
- Add `taken_at` (nullable TEXT, ISO 8601) column to the images table via
ensure_column migration and a new idx_images_taken_at index
- Populate taken_at in build_record via extract_exif_date, which tries
DateTimeOriginal → DateTimeDigitized → DateTime tags and rejects all-zero
sentinel dates written by uninitialised cameras
- upsert_image uses taken_at = excluded.taken_at so a re-indexed file gets
fresh EXIF; stale dates from replaced files are not preserved
- Add taken_asc / taken_desc sort using COALESCE(taken_at, created_at) so
images without EXIF gracefully fall back to their creation date
- Surface as "Taken: newest / oldest" in the Toolbar sort dropdown
- Shift map_image_row column indices after the new taken_at (index 10)
Adds a full discovery and organisation layer to the gallery.
## AI Tagger
- WD tagger (ONNX via ort) with DirectML/CPU acceleration
- Per-image and per-folder tag queuing; configurable batch size and
confidence threshold; model downloaded on first use via ureq/zip
- Tags stored with source ('ai' | 'user'); user tags are never
overwritten by AI; AI tags protected from accidental promotion
- Tagger pause/resume per folder; in-flight batches discarded cleanly
on pause or cancellation without leaving jobs stuck in processing
## Semantic & Tag Search
- CLIP text-query embedding via candle (HuggingFace hub model)
- Progressive candidate doubling with filter post-processing so
folder/rating/media-kind filters do not silently under-return results
- Tag search with DB-backed pagination (offset + COUNT total)
- Filename search unchanged; prefix syntax: s:, t:, f: in search bar
## Similarity Search
- HNSW in-memory index (hnsw_rs) with monotonic embedding_revision
counter for cache invalidation; build_index retries if a concurrent
write advances the revision during construction
- Folder-scoped similar search uses brute-force cosine scan (no k limit)
- Region-based similarity: crop an arbitrary rectangle in the lightbox,
embed it with CLIP, find the nearest images globally or within folder
- Pagination for both similar and region results; scope toggle
(all media / current folder) re-runs the query without reopening image
## Duplicate Finder
- Three-phase detection: stat (size) → sample hash (4×16 KB windows)
→ full-file hash (xxh3, large files only) to eliminate false positives
- Filesystem-first deletion: only removes DB rows for files successfully
deleted from disk; failed files remain visible for retry
- Persisted scan cache (SQLite) with invalidation on reindex and deletion;
both global and per-folder scopes invalidated after any deletion
## Tag Cloud & Explore
- Visual cluster explore: k-means over CLIP embeddings, configurable k,
representative thumbnail per cluster; cache keyed on xxh3 of embedding set
- Tag explore: ranked tag list with image counts and representative
thumbnail per tag; invalidated when AI tagging completes or folder removed
- Tag autocomplete for search bar
## Folder Management
- Inline rename (display name only, not OS rename)
- Relocate: file-picker to update folder path; all image paths rewritten
using SUBSTR prefix replacement to avoid corrupting paths that contain
the folder name as a substring
- Missing-folder recovery banner: Locate or Remove, never silent deletion
- Right-click context menu on sidebar items: Reindex, Rename, Locate,
Remove; hover buttons preserved alongside context menu
## Background Tasks
- Per-folder progress panel with embedding, tagging, caption, and
thumbnail stage breakdown
- Retry button per task for failed embeddings and tagging jobs
- Completed-task notifications (system tray via tauri-plugin-notification)
- Scan errors shown inline; WalkDir permission errors protect existing
records from deletion rather than cascading data loss
## Backend correctness
- sqlite-vec DML performed outside transactions throughout (virtual-table
limitation); embedding revision incremented on delete as well as insert
- Tagging job discard checks status = 'processing' so paused jobs reset
to 'pending' are also skipped, not just cancelled ones
- Stale async responses in Lightbox guarded with cancellation flags and
currentImageIdRef for both tag-load and tag-add callbacks
- Duplicate cache cleared on reindex; folder-removal clears vector rows
outside transaction before deleting the folder row
- Fix root cause: embedding_source_path() returns Result<PathBuf>, returning
Err for videos without a thumbnail instead of silently falling back to the
raw .mp4 path that CLIP cannot decode
- indexer: split embedding batch into pre-failed (no source) and embeddable
jobs; pre-failed are marked immediately without hitting the CLIP model
- db: retry_failed_embedding_jobs skips videos still without a thumbnail so
they no longer re-fail immediately on retry
- Add get_failed_embedding_images command listing failed files + error per folder
- Gallery: amber warning badge on tiles with embedding_status = 'failed'
- BackgroundTasks: fetch and show failed filenames/errors in expanded panel
- Toolbar: conditional 'Failed Embeddings' amber filter pill shown when any
folder has embedding_failed > 0; filters at DB level via new
embedding_failed_only param on get_images / count_images
- TagCloud: replaced vocabulary/dictionary label system with representative
image thumbnails per cluster; results cached in SQLite by image-id hash
Introduces an Explore view with a tag cloud that clusters image embeddings
using cosine k-means and labels clusters via vocabulary-nearest-neighbour
CLIP matching. Vocabulary embeddings are disk-cached (FNV hash-keyed) to
avoid redundant inference. Enables CUDA for candle dependencies and adds a
build.rs check that surfaces a clear error when the toolkit is missing.
- make Candle CUDA support opt-in so default builds work on CPU-only machines
- improve semantic search loading and empty states in the gallery
- keep semantic search UX clearer when no matches are found
Refs: #4
- add semantic text search with toolbar mode switching and sqlite-vec query support
- improve embedding progress visibility, failure recovery, and similar-image affordances
- add search clearing and keyboard controls for filename vs semantic search modes
- refine background task interactions and gallery/lightbox embedding states
Refs: #4
- add Candle + HF Hub CLIP image embedding pipeline with background embedding worker
- write image embeddings into sqlite-vec and expose similar-image lookup through a new backend command
- surface embedding progress and recovery in the UI, including retries for failed embeddings
- improve gallery/lightbox embedding UX and make similar-image actions directly accessible
Refs: #3, #4
Sets up Tauri v2 + React frontend with SQLite metadata store,
sqlite-vec for CLIP embedding infrastructure, and r2d2 connection
pool replacing the single Arc<Mutex<Connection>>. Indexer now uses
rayon for parallel file metadata collection.
