New SearchIndex struct in searchindex.go:
- Background build fetches top 1000 LB artists, then their top 10
release groups and top 10 recordings (2001 API calls total)
- Dedicated 3 req/s rate limiter for indexer (LB allows 30/10s)
- Bounded concurrency (3 goroutines) with progress logging
- Batch INSERTs in transactions of 100 rows
- FTS5 query with prefix matching ('for you' → 'for* you*')
- Results sorted by popularity descending
- Skips rebuild if index is < 7 days old
- Marks index ready from existing rows if build fails
- Context cancellation for clean shutdown
Add explore_index table (entity_type, mbid, title, artist_name,
artist_mbid, popularity, extra_json) with a unique index on
(entity_type, mbid). FTS5 virtual table explore_index_fts backed
by the content table with auto-sync triggers for insert/update/delete.
explore_index_meta table tracks build timestamps.
After MB search + popularity reranking, browse the discographies of
the top 3 artists and fuzzy-match the full query against album titles.
Matching albums not already in results are injected at the front.
Fuzzy matching uses substring containment with word-level ratio
(handles 'for you tatsuro' → 'FOR YOU' at 0.667) and word overlap
as fallback. Threshold: 0.4 ratio.
Example: 'for you tatsuro' now finds FOR YOU by 山下達郎 even though
MB text search treats 'for' and 'you' as stop words and never
returns it. The album is found via Yamashita's cached discography.
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.
Drop artists and recordings with blended score < 25 after popularity
reranking. Cap each entity slice to 15 server-side. Request 20 from
MB to allow filtering headroom. Reduces payload size and noise.
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.
After MB search returns text-relevance-scored results, fetch bulk
popularity data from ListenBrainz (POST /1/popularity/{artist,
recording,release-group}) for all result MBIDs. Blend scores:
final = 0.6 * mb_relevance + 0.4 * log10_popularity
Log-scale normalization ensures massive artists don't drown out
everything, but popular results rise above obscure exact matches.
Release groups (no MB score) sort by raw popularity.
Three LB POST calls run concurrently — each hits a different
endpoint. All are rate-limited and cached (24h TTL).
Example: searching 'tatsuro' now ranks Tatsuro Yamashita (2.5M LB
listens, score 97) above 'tatsuro' vocaloid producer (4 listens,
score 64) despite the latter being an exact name match on MB.
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.
The ListenBrainz popularity API returns snake_case JSON fields
(recording_name, artist_name, total_listen_count, recording_mbid)
but LBTopRecording used camelCase JSON tags for Wails serialization.
All fields silently deserialized as zero values — empty strings and
zero counts — producing ~8000 blank rows in the top tracks section.
Fix: add lbTopRecordingWire with snake_case tags for API unmarshal,
convert to LBTopRecording (camelCase) for Wails. Cap results at 10
to avoid rendering thousands of rows for prolific artists.
The mapTrackRow signature was extended with playCount and lastPlayed
fields in the play history feature, but the scan_test.go callers
were not updated, breaking go vet and golangci-lint.
When seeking, the underlying decoder position was updated but the
BufferedStreamer's ring buffer still contained up to 2 seconds of
pre-seek audio data. The speaker would drain this stale buffer
before playing audio from the new position, causing an audible
delay where the old position's audio continued playing.
Add a Flush() method to BufferedStreamer that resets the ring buffer
pointers, and call it in seekLocked() immediately after a successful
seek. This ensures the speaker starts playing from the seeked
position without any stale audio artifact.
- 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.
COALESCE(last_played, '') returned empty string which can't scan into
time.Time. Removed COALESCE, use sql.NullTime instead. Format to string
only when Valid.
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.
Migration 10:
- play_history table (audio_file_id FK, played_at DATETIME, CASCADE delete)
- play_count + last_played columns on audio_files (denormalized)
- Recreated track_metadata VIEW with play_count and last_played columns
Play recording:
- queue.recordPlay() inserts play_history row + updates denormalized columns
- Called from OnPlaybackFinished after queue advance completes
- Mutex released before DB write to avoid MaxOpenConns(1) deadlock
- Natural finish only — skip/stop does not count
Tests:
- TestMigration10PlayHistory: schema, columns, VIEW, round-trip verification
- All 49 smart playlist + 15 service + existing DB tests still pass
- 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)
- Add blank lines before cuddled expressions in wav_test.go
- Fix cuddled copy expression in wav.go writeRIFF
- All WAV lint issues resolved (remaining are pre-existing in other files)
