Extract primary English alias from MusicBrainz artist data when the
canonical name uses non-Latin script (CJK, Cyrillic, etc.). Display
it as the primary name in search results and artist detail header,
with the native script name as a subtitle beneath.
Example: 山下達郎 now shows 'Tatsuro Yamashita' prominently with
'山下達郎' as a subtitle. Artists with Latin names are unchanged.
Don't fire search for single-character queries — show 'Keep typing…'
instead. Cap rendered results at 10 per section (artists, albums,
tracks) to reduce noise. Top results already capped at 3.
Use MusicBrainz secondaryTypes to distinguish studio albums from
compilations, soundtracks, live albums, remixes, etc. Albums with
no non-studio secondary types show under 'Albums'; everything else
under 'Other Albums'. EPs and Singles remain their own sections.
Section order: Albums → EP → Single → Other Albums → ...rest.
- Column accessor shows '0' instead of empty string for unplayed tracks
- recordPlay emits TrackMetadataChanged event after updating DB
- Frontend library store invalidates on that event, refreshing play counts
Backend validation rejected 'playCount' as unknown column ID, silently
preventing it from being enabled or persisted. Added ColPlayCount to
the tracklist package's constant list and AllColumnIDs slice.
Backend:
- GetAllTracksWithFullMetadata queries now select play_count and last_played
- mapTrackRow accepts and passes through PlayCount/LastPlayed
- PlayCount + LastPlayed added to library.Track struct
- sqlcgen Row types updated with new fields
Frontend:
- PlayCount + LastPlayed added to library.Track TypeScript model
- 'Plays' column added to track-list column definitions (60px, right-aligned, sortable)
Queries without play data (search, genre, album) pass 0/empty defaults.
Backend:
- Added play_count and days_since_played to rule engine field whitelist
- days_since_played uses julianday() expression with COALESCE for NULL handling
- Never-played tracks (NULL last_played) match 'greater_than' but not 'less_than'
- Added PlayCount + LastPlayed to library.Track struct
- Evaluate query selects play_count and last_played from track_metadata
- Added play_count to sort field options
Frontend:
- Added play_count and days_since_played to field and numeric field lists
- Added play_count to sort options
All 49 rule engine + 15 service tests pass unchanged.
- Grid rows use align-items: stretch so all cells share the select's height
- Combobox host, wrapper, and input all set height: 100% to fill the cell
- Remove button uses align-self: center to stay centered instead of stretching
Details view:
- Skip evaluation on new playlists (was returning all 25k tracks)
- Go straight to editor on auto-edit instead of awaiting loadTracks
Editor:
- Default sort to Random instead of None, remove None option
- Hide sort direction button when sort is Random
- Fixed-width field (160px) and operator (140px) columns, value fills remaining space
- Preview fills remaining vertical space (flex layout) instead of fixed 200px max-height
- Preview scrolls independently while rules/options stay pinned
Combobox:
- Accept free-form text on blur and Enter — no longer requires selection from dropdown
- Enables typing values like 'indie' that may not be exact DB entries
Backend:
- Case-insensitive text matching: COLLATE NOCASE on is/is_not/is_any_of operators
- Applies to both regular fields and genre subqueries
- LIKE operators were already case-insensitive (SQLite default)
- track-list: branch on selection count, resolve tracks from this.tracks
- cover-grid: branch on selection count, resolve from expandedTracks
- queue-panel: branch on indices count, resolve via libraryStore.getCachedTracks
- playlist-details: branch on selection count, resolve via libraryStore
- Each view determines coverArt/coverArtMixed state and calls showBatch()
- showBatch() API for multi-track entry with merged field values
- Three-state field model: keep/set/clear via dirty tracking in editValues
- Confirmation dialog showing field changes before batch save
- Progress bar with live counter wired to BatchWriteProgress events
- Cancel button calling CancelBatchWrite during batch write
- Results view with success/failure counts and expandable failure details
- Batch cover art: pick, preview, or clear for all selected tracks
- Post-save data refresh returning to updated summary view
- Single-track show() path unchanged (batchMode = false)
- Add BatchFailure and BatchResult types for structured batch outcomes
- Add cancelBatch channel and suppressEvents flag to TagWriter struct
- Add CancelBatchWrite method for mid-batch cancellation from frontend
- Add BatchWriteTrackTags method processing tracks sequentially
- Emit BatchWriteProgress event per-track with current/total/succeeded/failed
- Suppress per-track TrackMetadataChanged; emit single event after batch
- Wails bindings auto-generated for BatchWriteTrackTags and CancelBatchWrite
- tagwriter namespace with BatchResult/BatchFailure in models.ts
After a successful save, re-fetch albums alongside tracks and re-resolve
cover art URLs from the updated album data. Previously the dialog only
refreshed this.track but kept stale this.coverArt URLs pointing to the
old content-hash files, causing the image to revert until reopen.
Three issues fixed:
1. asBytes() helper for []interface{} → []byte conversion — same
float64 deserialization issue as numeric fields. Cover art data
from the frontend arrives as []interface{} of float64, not []byte.
2. DB sync for cover art — was a placeholder no-op. Now saves image
to covers cache dir (content-hash dedup + thumbnail generation),
upserts cover_art row, and updates release_groups.cover_art_id.
Clear sets cover_art_id to NULL on linked release groups.
3. Frontend ReadFile returns base64 string (Go []byte JSON encoding),
not number[]. Decode with atob() before creating Uint8Array for
preview blob URL.
After saveEdit() succeeds, re-fetch tracks from library store and update
this.track with the fresh data so the dialog shows updated values instead
of the stale snapshot passed via show().
- Wire saveEdit() to WriteTrackTagsByPath with diff-only TagChanges map
- Add cover art selection via ImageFilePicker with instant blob preview
- Add cover art removal (× button) with clearCoverArt state
- Show saving indicator and disable buttons during save
- Display errors inline in action bar; edit mode stays active on error
- Add ReadFile Go method on FrontendUtil to read cover art bytes
- Add Wails binding for ReadFile
- Clean up all edit state (editValues, pendingCoverArt, errorMessage) on close/cancel
- LibraryStore now listens for TrackMetadataChanged and invalidates all caches
- Track Details context menu item visible for any right-clicked track in all 4 views
- Removed selectionCount === 1 gate from track-list, queue-panel, cover-grid, playlist-details
- WriteTrackTagsByPath resolves filePath to trackID via GetAudioFileByPath
- ImageFilePicker opens native file dialog filtered to JPEG/PNG
- Added Wails TypeScript bindings for both new methods
- Add ScanHooks callback struct to library package (follows RemovalHooks pattern)
- Move phantom resolution from library to playlist service via hook
- New ResolvePhantomTracksAfterScan reads M3U8 files and resolves paths
against current audio_files using multi-root resolution
- Handles pre-existing phantoms (match by M3U8 position) and new ones
(match by phantom_file_path)
- Delete old resolvePhantomTracks method that required phantom_file_path
- Wire ScanHooks in app.go OnStartup
- Event delegation handlers were attached in firstUpdated(), but the
virtualizer is conditionally rendered (hidden when tracks empty/loading)
- On first render, tracks are [] so virtualizer doesn't exist, and
firstUpdated() never fires again — delegation was never attached
- Move delegation to a guarded helper called from both firstUpdated()
and updated(), so it attaches as soon as the virtualizer appears
- Fixes click, multi-select, context menu, double-click, and drag in
both track-list and queue-panel components
- Replace wa-icon shadow DOM with inline SVG in queue-panel (xmark)
and album-dropdown (fav icons) to eliminate per-item shadow roots
- Memoize getBeforeEntries/getAfterEntries in cover-grid to prevent
.slice() creating new array refs that trigger virtualizer relayout
- Remove transition: scale and border-radius from album cards to
avoid per-frame repaints and anti-aliased path clipping
- Add queueMicrotask batching to player-store and favorites-store
notify() to coalesce rapid-fire updates into single renders
display:none discards scrollTop in WebKitGTK, so navigating away
from album/artist/genre grids and back reset scroll to top.
Replace inline style.display toggling with a CSS class that uses
visibility:hidden + height:0 + overflow:hidden. This collapses
the element visually while keeping the DOM alive with its scroll
state intact. contain:strict on hidden views ensures zero layout
cost while collapsed.
Targeted optimizations for the DMABuf-disabled rendering path where
every frame is software-composited:
- Replace infinite CSS scroll-text animation with transition-based
cycle that only repaints during active scroll, not during pauses
- Remove CSS mask-image on scrolling text (mask + animation was the
single most expensive continuous repaint)
- Replace wa-icon in track rows with inline SVG — eliminates 30-50
shadow DOM trees (each with SVG fetch/parse) during scroll
- Remove hover transitions on album cards, artist cards, genre cards,
fav icons, queue remove buttons — each transition was causing
per-frame software repaints
- Use visibility:hidden instead of opacity:0 for queue remove button
(binary switch vs per-frame alpha blend)
- Add decoding=async to now-playing cover art images (prevents
main-thread blocking during image decode on track change)
- Add contain:strict to fixed-height track rows (33px) and queue
items (49px) — browser skips size contribution calculations
Root causes addressed:
- track-list had no _itemSize hint for flow layout — virtualizer
defaulted to 100px, measured actual ~33px rows, then called
_correctScrollError/scrollTo on every scroll causing visible jumps
- will-change:transform on virtualizer elements caused nested GPU
layers (virtualizer positions children with transforms internally)
adding compositor overhead instead of helping
- content-visibility:auto on album cards conflicted with virtualizer's
own DOM recycling, causing redundant layout recalculation
- track-list visibilityChanged handler wrote to store synchronously
on every event (per-item during scroll) without any throttling
- IIFE closure in renderTrackRow created a new function per row per render
Fixes applied:
- Add _itemSize:{height:33} + fixed height:33px on .track-row (matches
queue-panel pattern that already worked smoothly)
- Add overflow-anchor:none on track-list virtualizer
- Remove will-change:transform from all 6 scroll containers
- Remove content-visibility:auto from album cards
- RAF-throttle visibilityChanged scroll position saves
- Replace IIFE with direct cols.map() in template
contain:strict includes size containment which caused a timing issue
where the flex-based main-panel height wasn't resolved before the
virtualizer measured its container, resulting in track-list rendering
at ~20% height on first load until something triggered a relayout.
- Queue store now uses queueMicrotask batching (matching library store pattern)
- Library store adds changeGeneration counter incremented only on actual data changes
- LibraryController checks changeGeneration before requestUpdate, skipping loading-only transitions
- Reduces unnecessary component re-renders during data loading cycles
- Replace inline arrow closures in renderTrackRow with event delegation via data-index
- Replace inline arrow closures in renderTrackItem with event delegation via data-index
- Add delegated click/dblclick/contextmenu/dragstart handlers on virtualizer elements
- Remove button click in queue panel also delegated via closest('.remove-button')
- Zero new function objects created per renderItem call during scroll
- Replace 100ms debounced scroll save in cover grid with requestAnimationFrame throttling
- Position now saves continuously during scrolling (~16ms) instead of only after stop
- Cancel pending RAF in teardown() to prevent leaks
- Add overflow-anchor: none CSS to queue panel lit-virtualizer
- Keep monkey-patch for lit-virtualizer _correctScrollError with expanded comment explaining why CSS alone is insufficient
- contain: layout style on :host of all 6 scroll-heavy components
- contain: paint + will-change: transform on all scroll containers for GPU compositing
- content-visibility: auto + contain-intrinsic-size on .album-card for off-screen skip
- cover-grid, track-list, queue-panel, artists-view, genres-view, playlist-view
- Primary views (tracks, albums, artists, genres, playlists, settings) created once and kept in DOM
- Navigation toggles display:none/display:'' instead of destroying/recreating components
- viewCache Map bounded to 6 entries — no memory leaks
- Detail views (artist-details, playlist-details, genre-details) remain ephemeral
- Scroll positions naturally preserved by keeping DOM alive
- No virtualizer reinit, no data refetch, no image reload on navigation
- contain: layout style on .content-area to isolate main+queue from header/sidebar
- contain: strict on .main-panel for maximum layout isolation
- contain: layout style paint on .main-panel > * for paint containment per view
- contain: layout style paint on sidebar to isolate from main panel
- contain: layout style on .bottom-bar to isolate footer from content reflows
