A pasted Deezer artist link (or any Deezer-source artist click) opened the
wrong artist's header: deezer_id 525046 is stamped on 4 library rows (Kendrick
+ 3 others — an enrichment-corruption bug), and the library-upgrade lookup did
WHERE deezer_id=? LIMIT 1, grabbing an arbitrary row (Jorja Smith) while the
discography loaded fresh from Deezer (Kendrick) — a Frankenstein page.
find_library_artist_for_source now detects when a source id maps to >1 library
artist and refuses to guess: it skips the id-based upgrade (still allowing the
name fallback), so the caller renders the source artist directly — landing on
the correct artist. Unique ids are unaffected (no regression).
The underlying enrichment bug that writes one source id onto multiple artists
is separate and still worth a follow-up.
Schema: ALTER TABLE artists ADD COLUMN amazon_id TEXT with index, added via
_add_amazon_columns migration called after Discogs in _run_migrations.
SOURCE_ID_FIELD: add "amazon" -> "amazon_id" entry. find_library_artist_for_
source now looks up Amazon artists by slug before falling back to name match,
same as every other source. artist_source_detail already stamps artist_info
[source_id_field] = artist_id so the amazon_id is set on source-only payloads.
Tests: add "amazon": "amazon_id" to EXPECTED_SOURCE_ID_FIELD; revert test
assertion back to strict equality (SOURCE_ONLY_ARTIST_SOURCES == SOURCE_ID_
FIELD.keys() holds again now that amazon has a column).
Library upgrade: find_library_artist_for_source returned None immediately for
Amazon because SOURCE_ID_FIELD has no 'amazon' entry (no DB column for Amazon
artist IDs). The name-based fallback was unreachable. Fix: only skip the column
query when column is None, not the whole function — name lookup now runs for
any source when artist_name + active_server are provided.
Artist images: add AmazonClient._get_artist_image_from_albums so the standard
_get_artist_image_from_source path in metadata/artist_image.py can call it as
a fallback (same hook iTunes/Deezer/Discogs expose). Searches by unslugified
artist name, matches primary artist, fetches album cover from album_metadata.
Test: updated test_source_only_set_matches_mapping_keys → _contains_all_mapped_
sources to assert subset (not equality) — SOURCE_ONLY_ARTIST_SOURCES intentionally
includes sources without a DB column that rely on name-only lookup.
- Move the metadata and MusicBrainz-related tests into a dedicated tests/metadata subfolder.
- Keep the rest of the suite flat for now.
- Preserve the existing test filenames so the change stays organizational rather than behavioral.
