New core/genre_filter.py with ~180 curated default genres. When strict
mode is enabled in Settings → Library Preferences → Genre Whitelist,
only whitelisted genres pass through during enrichment. Junk tags from
Last.fm (artist names, radio shows, playlist names) are silently dropped.
Applied at all 10 genre write points: Spotify, Last.fm, AudioDB, Deezer,
Discogs, iTunes, Qobuz enrichment workers + post-processing genre merge
+ initial download artist/album creation.
Strict mode is OFF by default — zero behavior change for existing users.
First enable auto-populates the whitelist with defaults. Users can add,
remove, search, and reset genres via the Settings UI.
Artists with an existing spotify_artist_id but NULL spotify_match_status
were fetched by the priority queue every ~3 seconds. _process_artist
returned early (preserving the ID) without marking the status, so the
same artist was re-queued indefinitely — burning CPU and inflating API
call counters. Now marks the artist as 'matched' on the early-return
path.
- Add interruptible stop events to background workers so shutdown
wakes out of long sleeps instead of waiting on fixed delays.
- Stop scan managers, repair worker, executors, and cleanup helpers
deterministically so process exit does not leave background threads
alive.
- Add startup warnings for stale SQLite WAL/SHM sidecars so unclean
shutdowns are easier to spot before init/migration errors cascade.
- Prevent forced kills from leaving SQLite sidecars behind, which
made rollbacks to older branches fail with malformed database
errors.
API Call Tracker:
- Save/load 24h minute-bucketed history + events to database/api_call_history.json
- Persists across server restarts via atexit + signal handler hooks
- New record_event() for rate limit bans (called from _set_global_rate_limit)
- New get_debug_summary() for Copy Debug Info — 24h totals, peak cpm with
timestamp, per-endpoint breakdown, and last 20 rate limit events
- Fixed race condition: events iteration now inside lock during save
Spotify Rate Limit Mitigation:
- Enrichment worker: max_pages=5 on get_artist_albums (was unlimited — artist
with 217 albums caused 22 paginated API calls, now capped at 5)
- Enrichment worker: inter_item_sleep raised from 0.5s to 1.5s
Spotify Re-Auth Fix:
- Both OAuth callbacks (port 8008 + 8888) now clear rate limit ban AND
post-ban cooldown after successful re-auth — Spotify usable immediately
instead of stuck on Deezer fallback for 5 minutes
- Auth cache invalidated on both global client and enrichment worker client
The original #221 fix only covered Genius and AudioDB. All other
workers (Spotify, iTunes, Last.fm, MusicBrainz, Deezer, Tidal,
Qobuz) had the same bug: enrichment overwrites manual match status
to not_found when name search fails. Each worker now checks for an
existing service ID before searching by name and returns early if
one exists, preserving the manual match.
The tooltip only checked paused/authenticated/idle/running states.
When Spotify was rate limited or daily budget exhausted, the worker
thread was still alive (sleeping in guards) so it showed "Running"
with no current item and stale 0% progress.
Now checks rate_limited and daily_budget.exhausted before running:
- Rate limited: "Rate Limited — Waiting Xm for rate limit to clear"
- Budget exhausted: "Daily Limit Reached — Resets in Xh Xm"
- No current item: "Waiting for next item..." instead of blank
Also adds rate_limit info object to get_stats() response for the
countdown display.
Artist/album/track matching previously took the first Spotify search
result above the 0.80 similarity threshold. If Spotify returned a
near-match before the exact match (e.g. "Brother's Keeper" before
"Brothers Keepers"), the wrong entity would be selected.
Now scores all candidates and picks the highest, so an exact match
(1.0) always wins over a near-match (0.94). No change to threshold
or batch matching logic — strictly better or equal results.
The background enrichment worker now caps itself at 3,000 processed items
per calendar day. Counter resets at midnight automatically. When exhausted,
the worker sleeps and checks every 5 minutes for a new day.
This is scoped entirely to the enrichment worker — user-initiated Spotify
API calls (searches, playlist ops, album lookups, etc.) are completely
unaffected. Budget status is exposed in the worker's get_stats() response
for the dashboard widget.
Helper system phases 2-7:
- Setup Progress: onboarding checklist with progress ring, auto-detection
via /status, /api/settings, /api/library, /api/watchlist, /api/automations
- Quick Actions: accent pill buttons in popovers (service cards get
"Open Settings" and "View Docs" actions)
- Keyboard Shortcuts: full-screen overlay with key cap styling, grouped
by scope (Global, Player, Helper, Forms)
- Search: fuzzy search across 200+ help entries, 11 tours, and shortcuts
with cross-page navigation via _guessPageFromSelector()
- What's New: version-tagged highlights with "Show me" navigation,
red badge on ? button for unseen versions, older version cycling
- Troubleshoot: scans dashboard service cards for disconnected/error
states, shows fix steps with action buttons, "All Clear" when healthy
- Contextual menu: page-aware tour suggestion at top of menu
- Ctrl+K / Cmd+K opens helper search globally
- First-launch welcome tooltip with pulsing ? button
- Redesigned floating button (48px, accent gradient, glass effect)
- Redesigned menu (unified card panel, accent left-stripe on contextual)
Enrichment worker fixes:
- AcoustID: individual recording matches downgraded INFO→DEBUG to reduce
log noise (14 lines for one track → 1 summary line)
- Name normalization: strip " - Suffix" dash format (Spotify) same as
"(Suffix)" parens format across all 8 workers. Fixes false mismatch
on tracks like "Electric Eyes (Studio Brussels Remix)" vs
"Electric Eyes - Studio Brussels Remix" (was 0.54, now matches)
- All 9 enrichment workers: stop auto-retrying 'error' status items (was infinite loop)
Only 'not_found' items retry after configured days; errors require manual full refresh
- Cover art dedup: check both 'pending' AND 'resolved' findings to prevent recreation
- Cover art scanner: top-level Spotify rate limit check skips Spotify entirely when
banned, falls back to iTunes/Deezer only, logs once instead of spamming 429s
Worker checked self.client.sp (non-None even without Spotify auth due
to fallback) instead of is_spotify_authenticated(). Searched via
iTunes/Deezer fallback, got numeric IDs, rejected them all with
warnings. Now sleeps when Spotify isn't authenticated instead of
making pointless fallback searches.
Pending count queries included NULL-ID rows that _get_next_item filters
out, so pending stayed > 0 even when no processable items remained.
Workers reported running instead of idle, UI never turned green. Added
AND id IS NOT NULL to _count_pending_items across all 9 workers to
match the _get_next_item filter.
Workers would endlessly match the same track because UPDATE WHERE id =
NULL matches 0 rows in SQL. Added AND id IS NOT NULL to all enrichment
queries (individual, batch EXISTS, and batch fetch) across all 9
workers. Also added process-level guard for belt-and-suspenders safety.
Fix Deezer get_track → get_track_details method name mismatch.
Add full-featured SpotifyWorker and iTunesWorker background workers to enrich artists, albums, and tracks with external metadata using batch cascading searches, fuzzy name matching, ID validation, and DB backfills. Update RepairWorker to re-read the transfer path from the database each scan, resolve host paths when running in Docker, and trigger immediate rescans when the transfer path changes; remove the static config_manager dependency. Also include supporting changes to the database layer and web UI/server (stats, controls, and styles) to integrate the new workers and reflect updated worker status.
