Add a disk-backed image cache with hashed browser URLs, SQLite metadata, size/type validation, stale fallback, and per-image fetch locking. Route normalized artwork through /api/image-cache while keeping /api/image-proxy as a compatibility shim, and align browser max-age with the image cache TTL. Add focused tests for cache behavior and image URL normalization.
Do not mark a monitored transfer as successful as soon as slskd reports completion. The monitor now only submits the post-processing worker; that worker reports the real success or failure after finding, verifying, and importing the file. If post-processing cannot be scheduled, mark the task failed and release the batch slot. Add a regression test for the premature success path.
Diagnostic-only change for issue Technodude reported: Tidal sync-playlist
downloads getting mass-cancelled mid-flight with no clear cause in the
logs. App.log shows ~91 second gaps between Tidal download start and
cancel — matches the monitor's 90s queue-timeout exactly — but none of
the monitor's WARNING log lines fire, so the trigger is ambiguous
between five `_should_retry_task` paths, three web_server cancel paths,
and the API endpoints.
Added a single `[CancelTrigger:<label>]` INFO log line immediately
before every `download_orchestrator.cancel_download(...)` call so the
next log dump pins down which path is firing.
Labels (grep-able, prefix tells the file, suffix tells the trigger):
monitor.not_in_live_transfers_90s
monitor.errored_state_retry
monitor.queued_state_timeout
monitor.stuck_at_0pct_timeout
monitor.unknown_state_no_progress_timeout
candidates.worker_cancelled_during_download
web.orphan_cleanup
web.cancel_download_task
web.atomic_cancel_v2
api.manual_cancel_single
api.public_cancel
The monitor's `deferred_ops` tuple grew from 3 elements to 4 (added
trigger label as last element). The dispatch loop unpacks both legacy
and new shapes so the change is backward-compatible for any in-flight
ops mid-deploy.
Zero behavior change. 367 download tests still green. WHATS_NEW left
untouched — diagnostic only, not user-facing.
After ship: ask Technodude to re-run the same sync playlist scenario,
attach the new app.log, grep `[CancelTrigger:` lines for the trigger
context, then write the actual fix.
The "Fix Unknown Artists" repair job crashed on every run with:
ImportError: cannot import name '_build_path_from_template' from
'core.repair_jobs.library_reorganize'
Commit ca5c9316 ("Rewrite Library Reorganize job to delegate to per-
album planner") moved the private path-builder + quality-string
helpers out of `core.repair_jobs.library_reorganize` and into the
import pipeline. `unknown_artist_fixer.py:163` still imported them
from the old module — its scan() defers the imports to avoid pulling
web_server's Flask boot into the test harness, so the broken target
only surfaces at runtime when the user actually runs the job. The
tool was completely unrunnable.
Re-wired the deferred imports:
core.repair_jobs.library_reorganize._build_path_from_template
-> core.imports.paths.get_file_path_from_template_raw
core.repair_jobs.library_reorganize._get_audio_quality
-> core.imports.file_ops.get_audio_quality_string
Both replacements have identical signatures + return shapes (verified
by inspecting library_reorganize's pre-refactor implementations vs
the import-pipeline equivalents):
get_file_path_from_template_raw(template: str, context: dict)
-> tuple[folder: str, filename_base: str]
get_audio_quality_string(file_path: str) -> str
No call-site changes needed beyond the import target.
2 new regression tests in `tests/test_unknown_artist_fixer.py`:
test_deferred_path_imports_resolve — runs the same import
statements scan() runs, so the NEXT refactor that moves these
helpers fails CI rather than reaching the user.
test_deferred_path_helper_shape_matches_fixer_usage — pins the
`(folder, filename_base)` 2-tuple contract the fixer's unpack
relies on. Catches return-shape drift even when the import
target stays valid.
Audited every consumer of `core.repair_jobs.library_reorganize` —
only one stale import (this file). The test suite covers the only
production caller.
5 fixer tests pass (3 existing + 2 new regression guards).
When a file failed AcoustID verification and got quarantined, the next
auto-wishlist cycle would search for the same track, the deterministic
quality picker would re-select the same (uploader, filename) source,
re-download it, and re-quarantine it. Users woke up to hundreds of
duplicate .quarantined entries from a single bad upload — same source
URL repeatedly, byte-for-byte identical files.
Root cause: `SoulseekClient.filter_results_by_quality_preference` ranks
candidates by quality + bitrate density only. Quarantine history wasn't
consulted, so a high-bitrate FLAC upload with a wrong-track AcoustID
fingerprint kept winning the picker against every other candidate.
Fix shape:
- New helper `core/imports/quarantine.py::get_quarantined_source_keys`
reads every quarantine sidecar's `context.original_search_result`
and returns the set of `(username, filename)` tuples for O(1)
membership checks. Sidecars missing the context field (legacy thin
sidecars written pre-Feb 2026, or orphaned files) and corrupt JSON
are skipped silently — defensive against transient FS / encoding
issues.
- `SoulseekClient._drop_quarantined_sources` runs the membership
filter against incoming TrackResults, drops matches, logs a single
INFO line with the skip count. Called first inside
`filter_results_by_quality_preference` so all four callers
(search-and-download, master worker, validation, orchestrator)
benefit transparently.
- Approving or deleting a quarantine entry removes its sidecar, so
the dedup key disappears from the set on the next search — gives
the user a way to opt back in to a previously-quarantined source
without restarting the app.
7 helper tests cover: missing dir, empty dir, well-formed sidecars
collected as tuples, legacy sidecars skipped, empty source fields
skipped (so empty-string keys can't accidentally drop unrelated
results), corrupt JSON tolerated, duplicate quarantines collapse.
5 integration tests pin: clean candidates pass, known-bad candidates
drop, missing quarantine dir returns input unchanged, filesystem
errors swallowed (defensive), full `filter_results_by_quality_preference`
runs the dedup BEFORE the quality picker — so a high-quality
quarantined source can't win on bitrate.
692 existing download + import tests still green. Cosmetic surface
of the fix is invisible — same UX as today when no quarantine entries
exist; loop only kicks in once a sidecar has been written.
Out of scope: bulk-select / multi-delete UI for the quarantine tab —
S-Bryce mentioned this as a separate pain point in the issue, but
it's its own UX work, not a one-commit drive-by.
S-Bryce reported that for some artists (Vocaloid producers, JP indie
acts, niche Western indie) the artist detail page was missing whole
release-groups visible on musicbrainz.org. Downloaded tracks from
those release-groups appeared in artist track counts but were not
bound to any visible album / single card — orphan "ghost" tracks the
user couldn't browse to.
Two duplicated bugs fed each other:
1. `core/musicbrainz_search.py` browsed MB release-groups with
`release_types=['album', 'ep', 'single']`. MB's primary-type
vocabulary is {Album, Single, EP, Broadcast, Other} — music
videos, one-off web releases, and broadcast singles use Other.
Pre-fix the filter dropped them at the API layer.
2. Three sites duplicated the same "raw primary-type → internal
album_type" mapping with slightly different vocabularies and all
silently defaulted unknown values (including 'Other') to 'album':
core/musicbrainz_search.py `_map_release_type`
core/metadata/types.py inline `{single:single, ep:ep}.get(...)`
core/metadata/cache.py Deezer-specific record_type guard
Letting Other through the filter without a real mapper would have
placed music videos in the Albums view alongside LPs — visually
misleading.
Fix shape:
- New `core/metadata/release_type.py` — single canonical mapper
consumed by every provider's raw→Album projection. Knows the full
MB vocabulary including 'other' and 'broadcast'; routes both into
the singles bucket since they're functionally single-track
releases. Compilation secondary-type override preserved (MB's
canonical Greatest-Hits pattern is `primary=Album,
secondary=[Compilation]`).
- `core/musicbrainz_search.py` `_map_release_type` becomes a thin
alias for the new helper so the six internal call sites stay
intact. API filter gains 'other'.
- `core/metadata/types.py` Album projection drops its inline mini-
mapper and calls the canonical helper. Now also handles the
compilation secondary-type override it was previously missing.
- The Deezer-specific cache.py guard stays as-is — Deezer's
record_type vocabulary is closed (album|single|ep), not affected
by this issue.
Verified end-to-end against MB for S-Bryce's artist (`46196b9c-affa-
4616-b53b-e967c8bd70e0`, inabakumori): pre-fix returned 22 release-
groups; post-fix returns 27, with the 5 extra all landing in the
Singles section with album_type='single' as intended.
23 new unit tests pin the mapper contract (case-insensitive primary
types, compilation secondary override, Other/Broadcast → single,
unknown → album default preserved, defensive empty/None inputs).
2 new tests in test_musicbrainz_search pin the API filter inclusion
of 'other' and the round-trip into the Singles bucket. All 516
existing metadata tests still green — refactor leaves historical
behaviour for {album, ep, single, compilation} unchanged.
When slskd_url is configured but the host is unreachable (slskd not
running, wrong port, host.docker.internal not resolving), the frontend's
/api/downloads/status polling fanned out to every download plugin
including Soulseek. soulseek_client._make_request hit a DNS / connect
failure on each poll and logged it at ERROR. Result: one
"Cannot connect to host host.docker.internal:5030" log line every
~2-3 seconds for the entire duration of any download — visible spam
even when the user wasn't using Soulseek at all.
Caught aiohttp.ClientConnectorError explicitly in both _make_request
and _make_direct_request. First failure emits one WARNING with
actionable context (start slskd, or clear soulseek.slskd_url if you
don't use Soulseek). Subsequent failures demote to DEBUG. The
_last_unreachable_logged flag resets on any successful (200/201/204)
response so a later outage warns again — suppression is per-outage,
not per-process-lifetime. Same shape as the existing _last_401_logged
suppression for auth failures.
The architectural gap (status polling fans out to soulseek even when
the user has soulseek disabled in their active download sources) is
intentionally left for a follow-up. The plugin-iteration code lives
in core/download_engine/engine.py and core/download_orchestrator.py;
threading a "skip-when-not-active" gate through every caller is a
bigger refactor than this user-facing log cleanup warrants. The
WARNING-once message tells the user what to do in the meantime.
5 new pinning tests cover the suppression contract: connection error
returns None (not raises), first failure WARNs + sets flag, repeats
stay quiet, successful response resets the flag, _make_direct_request
follows the same pattern, and non-connection exceptions still log at
ERROR so real bugs aren't hidden behind the new suppression.
The Fix Track Match modal's auto-search was hardcoded to query only
Spotify -> Deezer -> iTunes, ignoring MusicBrainz entirely — even for
users with MB set as their primary metadata source. MB-niche recordings
(canonical entries with diacritics, fringe / non-mainstream tracks that
the commercial catalogues don't carry) had no chance.
Wiring:
- New `MusicBrainzSearchClient.search_tracks_with_artist(track, artist,
limit)` for surfaces that already have title + artist split. Uses MB's
bare-query mode (strict=False) — diacritic-folded, alias/sortname
indexed — same recall rationale as the earlier MBID-paste endpoint.
- New route `GET /api/musicbrainz/search_tracks` mirrors the existing
/api/{spotify,itunes,deezer}/search_tracks endpoints exactly: accepts
`track`+`artist` (or legacy `query`) + `limit`, returns
`{tracks: [{id, name, artists, album, duration_ms, image_url, source}]}`.
Applies the same `core.metadata.relevance.rerank_tracks` pass Deezer /
iTunes use, which is critical because MB's free-text scoring weighs
title-text matches heavily and would otherwise rank cover / tribute
recordings above the canonical version.
- `_search_tracks_text` gains a `min_score` parameter. The cascade path
passes 20 (vs the enhanced-search-tab default of 80) so MB recordings
whose title doesn't literally contain the artist name still enter the
candidate pool — without that, "Army of Me" + "Bjork" only surfaces
the HIRS Collective cover (score 100) and drops Björk's canonical
recording (score 28). The rerank pass then surfaces Björk by artist
match. Verified against real MB API: pre-fix returned only the cover;
post-fix top 5 are all Björk.
- Fix popup `allSources` array (wishlist-tools.js) gets MB appended.
The existing `activeIdx` reorder logic moves MB to the front when
it's the active primary; otherwise MB sits last (1 req/sec rate
limit makes it the slowest source).
7 new unit tests on the adapter: bare-query mode is used, missing
artist falls back to None (drops AND-clause), empty inputs short-circuit,
low-score candidates are kept for rerank to handle, default strict +
default min_score behaviour preserved for the existing search-tab path,
client errors are swallowed so the cascade falls through to the next
source.
Discogs intentionally absent — Discogs has no track-level search API
(see core/discogs_client.py:575 — returns []). Adding a Flask endpoint
that always returns empty would be a permanent no-op.
Power-user escape hatch on the Discovery Fix Track Match modal — when
fuzzy auto-search ranks the wrong recording among many same-title
versions (10 remasters, live cuts, alt sessions), paste the MusicBrainz
recording URL or bare UUID into the new field and resolve straight to
that record.
Layout:
- Shape adapter `get_recording_flat(mbid)` lives in
`core/musicbrainz_search.py` next to existing `get_track_details`.
Returns the flat Fix-popup track shape (artists as `string[]`,
album as string, single `image_url`) — distinct from the
Spotify-shaped nested dict `get_track_details` returns.
- New route `GET /api/musicbrainz/recording/<mbid>` is a thin wrapper:
validates MBID format with an anchored UUID regex, calls the adapter,
returns 400 / 404 / 200 with no inline shape massaging.
- Frontend `parseMusicBrainzMbid()` lives in `shared-helpers.js` —
pure URL/UUID parser, reusable from other surfaces (failed-MB cache,
manual match) without duplication.
- Fix modal HTML gets one new input row + button; existing search row
and result render pipeline are untouched. New `lookupDiscoveryFixByMbid()`
fetches the endpoint and feeds the single result through the existing
`renderDiscoveryFixResults` -> confirm-dialog -> match pipeline, so MB-
paste matches go through the exact same selection flow as auto-search
results.
- Enter-key bound on the MBID input via a separate handler ref so its
lifecycle matches the search-input handlers without conflating the
two submit targets.
7 unit tests cover the adapter: happy path, empty/None MBID, MB returns
None, recording-without-release (empty album), multi-artist credits,
includes-list contract, and client-error swallow.
Out of scope: the Fix popup's fuzzy cascade is still hardcoded to
spotify/deezer/itunes regardless of which primary source the user has
configured. Adding MB to that cascade (when MB is the active primary)
is a separate concern.
Two bugs surfacing on the Fix popup and enhanced-search MB tab:
1. Strict Lucene phrase queries (`recording:"X" AND artist:"Y"`) killed
recall on user-facing manual search — diacritics ("Bjork" vs canonical
"Björk"), bracketed suffixes like "(Live)", and any AND-clause
mismatch returned zero results. Added `strict: bool = True` param to
`search_release` / `search_recording`; when False, sends a bare query
joining title + artist so MB hits alias/sortname indexes with
diacritic folding. `/api/musicbrainz/search` (Fix popup) and
`core/library/service_search.py` (service tabs) now pass strict=False.
Enrichment workers stay on strict mode — precision matters there
because they auto-accept the top hit above a confidence threshold.
2. Every MB album click was silently 404-ing — `_render_release_as_album`
passed `cover-art-archive` as an MB `inc` param, but it's not a valid
include for the /release resource (MB rejects with 400). The CAA flags
come back on every release response by default, so dropping the bad
include preserves the image-scope picker logic intact.
t2tunes uses HTTP 400 for transient Amazon-side failures instead of 5xx.
The first API call in a fresh session hit this every time, so album and
artist searches always failed while the track search (called 0.5 s later)
got through.
- _get_json: retry up to 3 times (1 s, 2 s backoff) on t2tunes-specific
400 "Failed to search" responses
- All search_raw calls switched from types="track,album" to types="track"
— t2tunes album-type queries are currently broken server-side; albums
and artists are now derived from track result metadata instead
- search_albums: drop is_album filter, extract album fields from track hits
- get_album_tracks: fall back to stream index (1-based) when t2tunes tags
omit trackNumber, preventing every track landing as track 01
URL-driven routing (PR #644) no longer passes the display name as a query
param to the artist-detail endpoint. The source-only detail builder fell back
to artist_id when artist_name was empty, surfacing the raw MBID as the page
title for MusicBrainz artists.
Two fixes in build_source_only_artist_detail:
- Drop the artist_id fallback in resolved_name so an MBID can never become
the display name
- Add a musicbrainz elif branch (matching the Spotify/Deezer/iTunes pattern)
that calls MusicBrainzSearchClient.get_artist() to resolve the real name
and genres from the MBID when no name is provided
Include cover-art-archive in the get_release call so _render_release_as_album
can check whether the representative release actually has front art before
building the URL. Prefer release-scope when confirmed present; fall back to
release-group scope otherwise. Prevents storing a release-group URL that CAA
reports as having no art.
- watchlist_scanner: fall back to album.image_url when album object has no
images list (affects MusicBrainz CAA URLs, iTunes, Deezer — all use
image_url on the Album dataclass, not the Spotify-style images array)
- Pulse Downloads nav icon while active downloads are in progress, same
pattern as watchlist scan animation
Add MusicBrainz watchlist artist ID storage, badges, linked-provider editing, and per-artist preferred source support.
Backfill watchlist MusicBrainz matches from already-enriched library artists so existing MusicBrainz worker matches appear in watchlist cards and settings.
Extend bulk watchlist add, liked artist matching, artist map source picking, and service status labels to recognize MusicBrainz, with regression tests for watchlist ID persistence and backfill.
Register MusicBrainz as a first-class metadata source alongside Deezer, iTunes, Spotify, Discogs, and Hydrabase. Expose the shared client through metadata services, add the settings option, and expand the MusicBrainz search adapter with source-compatible artist, album, track, and detail methods.
Carry MusicBrainz IDs through similar-artist discovery, recommended artists, artist map serialization, and personalized playlist selection. Update DB migrations and lookup filters so similar_artist_musicbrainz_id is preserved on older schemas and used for source requirements and library exclusion.
Normalize MusicBrainz album adapter output for import context and add regression coverage for registry mapping, typed album conversion, and similar-artist filtering. Verified by user with 120 focused tests passing.
Manual matches can be created from sync history as mirrored while wishlist and download flows later see the same track as wishlist or a provider source. Add a shared track-level lookup that falls back from exact source/id to source_track_id and title/artist, then use it for wishlist adds, cleanup, and download analysis so mapped tracks are not re-added or redownloaded.
Add coverage for mirrored-source matches being honored by wishlist cleanup and download batches, including the internal wishlist force-download path.
Ensure the Amazon enrichment worker verifies its required columns before querying pending work or progress, preventing upgraded installs from spamming no-such-column errors when amazon_match_status is missing.
Add regression coverage for legacy databases without Amazon enrichment columns.
Preserve source metadata for seasonal and cached discover album modals so artist links use real provider IDs instead of falling back to library/name routes.
Treat source-only artist detail discographies as clickable missing releases and skip library-only ownership/enhancement checks.
Artist detail pages previously always pushed /artist-detail to the URL,
so refreshing the page or sharing a link would drop users on a broken
empty page with no artist loaded.
URL format is now /artist-detail/:source/:id (e.g.
/artist-detail/spotify/4tZwfgrHOc3mvqsCAfo4LT or
/artist-detail/library/42). The source segment lets the backend
synthesize a response from the right metadata client without a DB hit.
Changes:
Client routing (legacy shell + TanStack bridge)
- buildArtistDetailPath / _getDeepLinkArtistDetail added to init.js;
parse both new :source/:id and legacy bare :id formats so old
bookmarks still work
- navigateToPage passes artistId + artistSource through to the router
bridge, which builds the dynamic href instead of hardcoding route.path
- resolveShellPageFromPath / resolveLegacyShellPageFromPath use a prefix
match so /artist-detail/* resolves to artist-detail page-id
- globals.d.ts typed for artistId / artistSource options
- activateLegacyPath and syncActivePageFromLocation (popstate) both
restore artist from URL using skipRouteChange:true to avoid a
re-navigation loop back to /artist-detail
- loadInitialData restores artist from URL on page load (router not yet
mounted at DOMContentLoaded so legacy path runs unconditionally)
- Same-artist guard in navigateToArtistDetail prevents double-fetch
when the router fires activateLegacyPath after the initial navigation
Server
- artist_source_detail.build_source_only_artist_detail now resolves
artist name from the source API when none is supplied, so deep-link
restores with an empty name string still render correctly
Tests
- test_spa_deep_linking: /artist-detail/42 and /artist-detail/spotify/ID
both serve index.html
- bridge.test.ts: source-aware URL building and library fallback
- route-manifest.test.ts: prefix path resolution
- artist_source_detail: name resolved from source when input is empty
Add service-level coverage for the Enhanced Library I Have This flow: copying an existing source file, writing the target album DB row, preserving source audio, inheriting album identity tags, and migrating older track tables that lack disc_number.
Move the existing-file missing-track import workflow out of web_server.py and into core/library/missing_track_import.py.
Keep the Flask route focused on request wiring and response formatting while the service handles staging copy, post-processing, album identity tag inheritance, DB upsert, and media-server sync.
Add a conservative Soulseek album preflight scorer so album downloads choose a coherent slskd folder before per-track enqueue. The scorer compares album title, artist, year, track count, tracklist coverage, peer quality, and penalizes unexpected deluxe/remix/live-style folders.
Preserve hybrid source priority by only running Soulseek album preflight when Soulseek is the selected source or first in the hybrid order. If Soulseek is only a fallback behind another source, the normal hybrid flow is left alone.
Reuse the richest wishlist album context across tracks in the same album group so release date, artwork, album type, and album artist stay consistent for path generation. Also preserve peer-quality tie breakers when attempting equal-confidence candidates.
Tests cover correct-folder selection over larger wrong editions, Soulseek primary vs fallback hybrid behavior, shared wishlist album context, and peer-quality candidate ordering.
Three ruff S110 violations replaced with logger.debug calls:
- amazon_client.py:527 duration backfill ASIN search
- amazon_client.py:679 album metadata fetch in _fetch_album_metas
- amazon_worker.py:401 artist image backfill from albums
- Artist cards, hero section, and enhanced view now show Amazon Music badges
when amazon_id is populated (AMAZON_LOGO_URL constant, orange #FF9900 brand)
- Enhanced view artist and album match status rows include amazon_match_status
chip with click-to-rematch via openManualMatchModal
- getServiceUrl: added amazon (album/track ASIN → music.amazon.com) and fixed
missing discogs entries; serviceLabels adds tidal/qobuz/amazon
- Enhanced view enhanced-artist-id-badges includes amazon_id entry
- DB SELECTs for library artists list and artist detail now return amazon_id;
both response dicts include the field
- watchlist_artists migration adds amazon_artist_id column
- Watchlist config GET: amazon_artist_id in SELECT/WHERE/response (index 18)
- Watchlist artists list response includes amazon_artist_id
- link-provider endpoint: amazon added to valid_providers and col_map
- _populateLinkedProviderSection: amazonId param + Amazon Music source row
- Watchlist card source badges render Amazon pill (watchlist-source-amazon CSS)
- _openSourceSearch labels map includes amazon
- service_search: amazon_worker injected via init(); _search_service amazon branch
uses search_artists/albums/tracks, same {id,name,image,extra} return shape
- _SERVICE_ID_COLUMNS: amazon → amazon_id for artist/album/track
- _init_service_search call passes amazon_worker_obj
- amazon_client._fetch_album_metas: 5-minute TTL cache per ASIN — cached hits
skip _rate_limit() and HTTP call entirely; fixes ~10s artist detail load
- registry.py: removed amazon from METADATA_SOURCE_PRIORITY and
METADATA_SOURCE_LABELS — T2Tunes has no discography API, cannot serve as a
primary metadata source; Amazon remains a download source + ASIN enricher
- Settings metadata source dropdown and help text updated accordingly
The cap caused albums beyond position 10 to load without art on the
artist detail discography. T2Tunes search_raw naturally returns ~20
results per query, so album_candidates is already bounded — no explicit
cap needed.
Two bugs in the library artist detail page when Amazon is the source:
1. No album art: get_artist_albums returned Album dataclasses with
image_url=None — it collected ASINs but never called _fetch_album_metas.
Now fetches metas for up to 10 albums (same cap as search_albums),
populating image_url, release_date, and total_tracks on each Album.
2. No singles: Album.from_search_hit hardcodes album_type="album" and
T2Tunes exposes no release type in search results. Added inference:
total_tracks==1 → album_type="single", which routes them to the
singles bucket in the discography categorizer.
Also passes album_name through _strip_edition and artist through
_primary_artist in get_artist_albums (parity with search_albums).
3. amazon_id missing from artist_source_ids in get_artist_detail:
the discography lookup never received the stored Amazon slug so
it always fell back to name search. Added 'amazon': artist_info.
get('amazon_id') to the dict alongside spotify/deezer/itunes/etc.
Background worker matching library artists/albums/tracks to Amazon ASINs
via T2Tunes search. Follows same 6-tier priority queue as Deezer/iTunes/
Spotify/Qobuz/Tidal workers. Backfills artist thumbnails from album cover
stand-ins (T2Tunes exposes no direct artist images).
- core/amazon_worker.py: new AmazonWorker class with full parity
- database/music_database.py: expand _add_amazon_columns to cover
amazon_id/amazon_match_status/amazon_last_attempted on artists,
albums, and tracks (was artists-only)
- web_server.py: import, init, register in enrichment panel, add to
scan pause/resume dicts and rate monitor key map
- helper.js: WHATS_NEW 2.5.3 entry for enrichment worker
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.
T2Tunes albumList entries may not include a release_date field, leaving the
$year path template empty. get_album() now falls back to the first track's
release_date (populated from the FLAC date tag via get_album_tracks) when
album metadata has none. Also try camelCase releaseDate key at all albumList
read sites (Album.from_metadata, get_album, _fetch_album_metas consumers).
1 new test: release_date backfilled from stream date tag when absent from
album metadata. date tag "2024-11-22" added to MEDIA_RESPONSE_FLAC fixture.
media_from_asin returns no duration data. get_album_tracks now does one
search_raw call using the album name + primary artist from stream tags,
filters hits by albumAsin == requested asin, and builds a duration_map
(track asin → duration_ms). Search failures are swallowed — duration_ms
falls back to 0 so the existing behaviour is preserved on error.
2 new tests: duration populated when search returns matching hit; duration
stays 0 when search endpoint returns an error.
release_date: T2Tunes album metadata may use camelCase releaseDate — try both
keys at all read sites (get_album, get_track_details, Album.from_metadata,
_fetch_album_metas consumers). Final fallback: s.date from stream tags, which
T2Tunes always populates from embedded FLAC/MP4 date tag. Wire s.date into
get_album_tracks items and get_track_details album.release_date so the $year
path template resolves correctly.
disc_number crash: .get('disc_number', 1) returns None when key is present but
value is None (Amazon stream info has Optional[int] for disc_number). Switch all
max() call sites and disc_num assignments to `or 1` guard:
- master.py: run_full_missing_tracks_process max() and disc_num read
- candidates.py: track_info and detailed_track disc_number reads
- web_server.py: enhanced and standard album download max() calls
AcoustID verification was quarantining every Amazon track because T2Tunes
embeds [Explicit] and [feat. X] in stream tag titles/artists, but AcoustID
returns bare titles — triggering version-mismatch rejection on every track.
- get_track_details: apply _strip_edition to name/album, _primary_artist to
artist; wire s.track_number / s.disc_number instead of hardcoded None
- get_album_tracks: apply _strip_edition to name, _primary_artist to artist
Also fix TypeError crash in album download paths when disc_number is None
(present in dict but explicitly None, so .get('disc_number', 1) returns None):
- master.py run_full_missing_tracks_process: or 1 guard on both max() and disc_num
- candidates.py track_info extraction: or 1 guard on both disc_number reads
- web_server.py enhanced + standard album download max() calls: or 1 guard
- All search_raw calls switched from single-type to types="track,album" — T2Tunes only
returns results when both types are requested together
- _fetch_album_metas: parallel fetch (up to 5 workers) of album cover art via
album_metadata(asin) — T2Tunes search results carry no image URLs
- search_tracks: populates image_url, release_date, total_tracks from album meta
- search_artists: strips feat. credits via _primary_artist() so "Artist feat. X" and
"Artist ft. Y" collapse to one "Artist" entry; uses album cover as artist image
stand-in (same approach as iTunes — T2Tunes has no artist images)
- search_albums: name-based dedup (display_name + artist key) instead of ASIN-based;
populates image_url, release_date, total_tracks from album meta (cap 10 ASIN fetches)
- _strip_edition(): strips [Explicit]/(Explicit) from track/album names — explicit is
the default version; Clean/Edited/Censored labels kept as-is so they stay distinct
- get_album(): applies _strip_edition to name and _primary_artist to artist so
MusicBrainz preflight matching doesn't fail on "[Explicit]" album names
- get_album_tracks(): populates track_number and disc_number from T2TunesStreamInfo
instead of hardcoding None — fixes track ordering in multi-track album downloads
- get_artist() / get_artist_albums(): _unslugify() converts slug artist IDs back to
search names; _primary_artist() in comparison handles feat-annotated results
- SOURCE_ONLY_ARTIST_SOURCES: added "amazon" so artist detail page doesn't 404
- build_source_only_artist_detail: added amazon_client param + dispatch branch
- web_server.py: resolve amazon_client in _build_source_only_artist_detail wrapper;
add source_override=="amazon" branch in get_spotify_album_tracks endpoint
- 77 tests covering all above paths; all pass
- Add 'amazon' to VALID_SOURCES (and transitively VALID_STREAM_SOURCES)
in core/search/orchestrator.py so the backend accepts it as a
requested source without returning 400
- Add resolve_client('amazon') case — mirrors musicbrainz pattern,
gets the cached AmazonClient from the metadata registry
- Add 'amazon' to _alternate_sources() so it appears as a tab when
another source is primary (always available, no credentials)
- Add SERVICE_CONFIG_REGISTRY entry 'amazon': {'always': True} so
/api/settings/config-status reports it as configured
- Add SOURCE_LABELS['amazon'] and SOURCE_ORDER entry in
shared-helpers.js so both enhanced search and global search show
the Amazon Music tab
- Add 'amazon' to _ALWAYS_CONFIGURED_SOURCES so the picker never
dims the tab (no credentials required)
- Add .enh-tab-amazon.active CSS (Amazon orange #FF9900)
- 3530 tests pass
Wires AmazonClient into the metadata source registry following the
exact same pattern as DeezerClient. No existing source paths touched.
- Add get_album_metadata / get_artist_info / get_artist_albums_list
aliases to AmazonClient (mirrors DeezerClient interface aliases)
- Register amazon in METADATA_SOURCE_PRIORITY and METADATA_SOURCE_LABELS
- Add _get_amazon_factory() + get_amazon_client() to registry.py
- Add amazon branch to get_client_for_source(); thread amazon_client_factory
kwarg through get_primary_client() and get_primary_source_status()
- Re-export get_amazon_client from the core.metadata_service shim
- Add Amazon Music option to Settings metadata source dropdown
- 3530 tests pass
The download monitor blocks post-processing with a bytes-incomplete guard:
if size > 0 and transferred < size: continue
_stream_to_file throttles engine updates to every 0.5s. The last tick before
the file finishes typically leaves transferred slightly below the Content-Length
size in the engine record. Other streaming clients (YouTube, Tidal, HiFi, etc.)
use their own download threads and don't track bytes at all, so size stays 0
and the guard is always skipped. Amazon was the only client hitting it.
Fix: just before returning the file path from _download_sync, write a final
engine record update setting size == transferred == out_path.stat().st_size
(the decrypted output size). The bytes-incomplete guard then sees
transferred == size and falls through to trigger post-processing normally.
`get_all_downloads` was calling `engine.get_all_records()` — a method that
doesn't exist on DownloadEngine. Same story for `cancel_record` and
`clear_completed`. The engine exposes `iter_records_for_source`, `get_record`,
`update_record`, and `remove_record` — matching what every other streaming
client (Deezer, HiFi, Qobuz, SoundCloud, Tidal, YouTube) already uses.
With `get_all_downloads` silently returning `[]` on every call (the missing
method raised, `except Exception: return []` swallowed it), the download monitor
never saw Amazon records as complete — tasks stayed stuck at 0% even after the
file had fully downloaded.
Changes:
- `get_all_downloads` → `iter_records_for_source('amazon')`
- `get_download_status` → `get_record('amazon', id)`, no try/except
- `cancel_download` → `get_record` check + `update_record` (Cancelled) +
optional `remove_record` — same pattern as deezer/hifi/etc
- `clear_all_completed_downloads` → iterate + `remove_record` for terminal
states; returns True on no-engine (nothing to clear = success)
- `_record_to_status` drops the `download_id` argument; reads `rec['id']`
instead (worker stores `'id'` in every record — `iter_records_for_source`
returns the full record dict)
Tests updated to match: `iter_records_for_source` mock replaces
`get_all_records`, cancel test verifies `update_record`+`remove_record`,
clear test verifies only terminal-state records are removed, graceful-error
test replaced with no-records boundary test (exception propagation is handled
at the engine aggregator layer, not per-plugin).
The engine worker stores the encoded filename under the key 'filename'
(see worker.py dispatch). _record_to_status was reading 'original_filename',
which always returns "" — so every DownloadStatus emitted by
get_all_downloads/get_download_status had an empty filename string.
The download monitor builds lookup keys as
_make_context_key(download.username, download.filename). With filename=""
the key was always "amazon::" which never matched the task's
"amazon::B0B1234||Artist - Title" key. Monitor never detected Amazon
download completions, so tasks sat stuck at Downloading 0% forever even
though the files had actually downloaded.
Also fixes tests that had the same wrong key.
AmazonDownloadClient was missing set_engine() and set_shutdown_check().
The download engine auto-wires plugins by calling set_engine(self) at
registration time if the method exists (engine.py:136). Without it,
_engine stayed None forever, causing every download() call to raise
RuntimeError("_engine is not set") — silently failing and marking all
tracks not found.
All other streaming clients (Deezer, Qobuz, Tidal, HiFi, SoundCloud)
expose set_engine(); Amazon now matches the pattern.
Tests added: set_engine wires _engine, set_shutdown_check wires callback,
set_engine unblocks download dispatch (the exact live failure mode).
`validation.py` had amazon absent from `_streaming_sources`, causing
Amazon TrackResult objects (bitrate=None, size=0) to fall through to
the Soulseek P2P code path and get rejected by
`filter_results_by_quality_preference`. Every album track was marked
not found.
Fix: add 'amazon' to every streaming-source guard tuple/set that was
previously missing it:
- core/downloads/validation.py — primary bug fix (quality-filter bypass)
- core/downloads/status.py — _STREAMING_SOURCE_NAMES frozenset
- core/downloads/task_worker.py — hybrid fallback client map
- core/imports/side_effects.py — || filename→stream-id extraction
- web_server.py — is_streaming_source, transfer list display,
candidate source label, _try_source_reuse, _store_batch_source
- tests/test_download_plugin_conformance.py — registry count + parametrize
Also updates the 2.5.3 What's New entry to drop the stale
"not yet wired" disclaimer.
Follows the exact same standard as Tidal, Qobuz, HiFi, and Deezer.
registry.py — import + register AmazonDownloadClient as 'amazon'.
amazon_download_client.py — read amazon_download.quality / allow_fallback
from config on init; pass quality as preferred_codec to AmazonClient;
_download_sync codec waterfall respects allow_fallback flag.
download_orchestrator.py — reload_settings() updates preferred_codec +
allow_fallback on the live client after a settings save. 'amazon' added
to _streaming_sources so search_and_download_best routes it correctly.
api_call_tracker.py — 'amazon' registered in RATE_LIMITS (120/min),
SERVICE_LABELS, and SERVICE_ORDER so API call monitoring shows Amazon.
web_server.py — 'amazon_download' added to the settings service loop.
'amazon' added to serverless_sources (no slskd probe needed). Streaming
file-finder extended to handle amazon username + ||asin||title encoding
(extension-less fuzzy match, same as Tidal/Qobuz/HiFi). New endpoint:
GET /api/amazon/test-connection → checks T2Tunes proxy status.
webui/index.html — amazon-download-settings-container: quality dropdown
(flac/opus/eac3), allow-fallback checkbox, test-connection button.
webui/static/settings.js — 'Amazon Music' added to HYBRID_SOURCES,
_hybridSourceEnabled, allSources mode list, loadSettings(), saveSettings()
payload, updateDownloadSourceUI() show/hide + auto-test. New
testAmazonConnection() function.
