- Move /api/artist/<artist_id>/image resolution into core.metadata_service.
- Resolve artist artwork through source priority, with explicit source/plugin overrides preserved.
- Keep Spotify call tracking inside the client layer to avoid double counting.
- Update similar-artist lazy loading to pass source context and add service coverage.
- Relocate the streamed MusicMap similar-artist flow out of web_server.py and into core.metadata_service.
- Match similar artists through the configured source-priority chain instead of assuming Spotify first.
- Add iTunes artwork fallback so streamed artist payloads still carry image_url when search results are sparse.
- Cover the new service behavior with tests.
Artist detail pages ran check_album_exists_with_editions and check_track_exists
per discography item, each firing 5+ title variations times 3 artist variations
of fuzzy LIKE searches plus fallback broad-artist queries. For a 30-album artist
that was ~450 SQL round-trips just to answer "which of these do I own."
Hoist the artist's library albums and tracks into memory once per request via
two new helpers — get_candidate_albums_for_artist and get_candidate_tracks_for_albums —
and thread them through as optional candidate_albums / candidate_tracks params on
check_album_exists_with_editions, check_album_exists_with_completeness,
check_track_exists, check_album_completion, and check_single_completion.
Batched path scores the same _calculate_album_confidence / _calculate_track_confidence
against the in-memory list, preserving Smart Edition Matching and accuracy.
Title-only cross-artist fallback still fires for collaborative-album edge cases.
None on either param preserves legacy per-item SQL behavior for unaffected callers.
Applied to both /api/library/completion-stream (library artist detail page) and
iter_artist_discography_completion_events (Artists search page). Timing logs
added to confirm the pre-fetch cost and loop elapsed time.
On a Kendrick page load, per-album resolution drops from ~8 seconds to under
the 50ms streaming sleep floor. Observed ~100x SQL reduction on the happy path.
- collapse old multi-line debug bursts into single structured rows
- remove leftover DEBUG-style prefixes from message text
- keep the app log readable without losing useful trace detail
- Move album-track resolution into metadata_service
- Use the configured provider order instead of Spotify-first branching
- Switch the frontend to the unified /api/album/<id>/tracks endpoint
- Add tests for source-priority lookup, DB resolution, and formatting
- pass provider-specific artist ids into the source-priority discography lookup
- stop relying on the local library artist id when querying external metadata
- add a regression test for source-specific artist id resolution
- Stop passing in spotify_id as the id in the UI, use the actual db id instead
- Fixes an issue where albums for another artist would end up being returned for the actual searched artist
- Remove the redundant artist_id filtering code
- Fixes an issue where not-currently-owned albums would be filtered out from the results, even if they were successfully fetched from the configured metadata provider
- broaden the artist-detail dedup helper to catch trailing parenthetical edition and remaster variants
- keep the legacy hyphenated suffix fallback for older metadata
- add regression coverage for language-specific Edition and remaster cases
- move artist-detail discography resolution onto the shared source-priority metadata service
- keep the variant dedup helper in the UI-facing adapter
- pass the chosen source through completion checks
- add coverage for the new adapter and dedup behavior
Move completion checks into metadata_service and make them follow the configured metadata source priority.
Drop the old test-mode path, remove the web_server wrapper indirection, and keep artist inference on explicit release metadata instead of guessing from a track search.
Add coverage for the source-priority completion behavior and the safer artist-name handling.
Move Hydrabase availability checks into metadata_service so source resolution owns the policy. Keep web_server delegating to the centralized helper and add tests for the enabled/disabled cases.
Move artist discography resolution into core metadata_service, introduce MetadataLookupOptions, and keep web_server focused on request handling. Add focused tests for the new service boundary and preserve current fallback behavior for now.
Make discovery pool population respect provider priority while keeping Spotify strict, and reduce unnecessary request volume in the hot discovery paths.
- keep discovery fan-out source-priority aware
- preserve cache use where freshness is not required
- cap Spotify artist-album pagination in discovery and cache refresh paths
- keep incremental release checks to a single page, since they only need the newest releases
- add regression coverage for provider order, strict Spotify handling, and pagination caps
Centralize the ordered metadata source list and source-priority helper so album completeness and the repair worker follow the same Deezer/iTunes-first fallback order. This also removes the last duplicate priority logic from the touched repair paths.
Album completeness and any other repair job now uses the centralized source/client helpers instead of a worker-local Spotify client or override plumbing
- This keeps source selection aligned with the configured primary provider and removes the last Spotify-only special case from the job path.
This change ultimately is a step towards further centralizing the Spotify client access and the associated `is_spotify_authenticated` check.
- Currently these look-ups are done all over the place in different feature implementations directly, but moving forward, any feature that uses `get_primary_client` or `get_client_for_source` to access the Spotify client, won't have to duplicate any rate-limiting or auth checks as long as these getters are used
Album completeness and downstream repair flow now follow the configured
primary provider first, with Discogs and Hydrabase support added alongside
existing Spotify, iTunes, and Deezer paths.
Keep spotify_track_id for compatibility while preserving source-aware track
IDs for provider-neutral handling.
Stripped 4,200+ emoji characters from print(), logger calls across
39 Python files. Logs are now clean text — easier to grep, more
professional, no encoding issues on terminals without Unicode support.
Seasonal config icons preserved for UI display.
Clients are for the most part being initialized per-request, which leads to a lot of redundant client initialization, as well as noise on the logs, since each client initialization emits a row on the logs, eg. 'Deezer client initialized'
All callers of _create_fallback_client() and _get_configured_fallback_source()
now use get_primary_client() and get_primary_source() directly. No more
legacy alias usage anywhere in the codebase.
All metadata source decisions now flow through get_primary_source() and
get_primary_client() in core/metadata_service.py. Previously 6 different
files reimplemented this logic with inconsistent defaults ('itunes' vs
'deezer') and auth checks, causing bugs when any one was missed.
Changes:
- metadata_service.py: Added canonical get_primary_source/get_primary_client
- web_server.py: _get_metadata_fallback_source() and _get_active_discovery_source()
are now thin wrappers delegating to metadata_service
- seasonal_discovery.py: _get_source() delegates to metadata_service
- personalized_playlists.py: _get_active_source() delegates to metadata_service
- spotify_client.py: Fixed _fallback_source default from 'itunes' to 'deezer'
- watchlist_scanner.py: _get_fallback_metadata_client() delegates to metadata_service
Future changes to source selection only need to update one file.
- Remove redundant enable checkbox — fallback dropdown is the enable
- Hydrabase option only appears in dropdown when connected
- Connect/disconnect dynamically adds/removes dropdown option
- _is_hydrabase_active checks fallback_source == hydrabase (not config toggle)
- Fallback client returns hydrabase_client when selected, iTunes if disconnected
- Auto-reconnect respects fallback selection for dev_mode handling
- hydrabase added to settings save service list for persistence
- Status shows green Connected on page load when auto-connected
Users can now choose between iTunes/Apple Music and Deezer as their free
metadata source in Settings. Spotify always takes priority when authenticated;
the fallback handles all lookups when it's not.
Core changes:
- DeezerClient: full metadata interface (search, albums, artists, tracks)
matching iTunesClient's API surface with identical dataclass return types
- SpotifyClient: configurable _fallback property switches between iTunes/Deezer
based on live config reads (no restart needed)
- MetadataService, web_server, watchlist_scanner, api/search, repair_worker,
seasonal_discovery, personalized_playlists: all direct iTunesClient imports
replaced with fallback-aware helpers
Database:
- deezer_artist_id on watchlist_artists and similar_artists tables
- deezer_track_id/album_id/artist_id on discovery_pool and discovery_cache
- Full CRUD for Deezer IDs: add, read, update, backfill, metadata enrichment
- Watchlist duplicate detection by artist name prevents re-adding across sources
- SimilarArtist dataclass and all query/insert methods handle Deezer columns
Bug fixes found during review:
- Similar artist backfill was writing Deezer IDs into iTunes columns
- Discover hero was storing resolved Deezer IDs in wrong column
- Status cache not invalidating on settings save (source name lag)
- Watchlist add allowing duplicates when switching metadata sources
Introduces core/itunes_client.py implementing an iTunes Search API client for music metadata, providing search and lookup for tracks, albums, and artists with rate limiting. Adds METADATA-FALLBACK-IMPLEMENTATION.md, a comprehensive guide comparing fallback strategies for music metadata, including anonymous Spotify access and iTunes, and outlines integration approaches for seamless user experience without requiring Spotify credentials.
