Clicking a MusicBrainz album returned 404 because the browse-based
search path now stores release-GROUP MBIDs in Album.id, but `get_album`
still hit `/ws/2/release/<mbid>` directly. Release-group MBIDs don't
resolve as release MBIDs — MB 404s. User log:
GET /api/spotify/album/b88655ba...?source=musicbrainz → 404
Error fetching release b88655ba...: 404 Client Error
The fix requires a two-step resolution for the new browse path:
1. Look up the release-group with `inc=releases+artist-credits` to get
the list of releases inside (original + reissues + regional + promo
editions). MB release-groups routinely hold 5-20 releases.
2. Pick a representative release: prefer Official status over Promo,
prefer releases with a real tracklist over stubs, then earliest date.
3. Fetch that release's full tracklist via `get_release`.
Two extra seconds at the 1-rps rate limit, but it's on click, not on
search results rendering.
Structure:
- New `MusicBrainzClient.get_release_group(mbid, includes)` method.
- New `_pick_representative_release(releases)` helper encapsulates the
ranking logic.
- Tracklist projection extracted into `_render_release_as_album` so
both paths share the same shape construction.
- `get_album` tries release-group first; falls back to direct release
lookup when the MBID turns out to be a release from the text-search
fallback path.
- Canonical Album.id stays the release-group MBID so a re-fetch with
the same URL hits the same code path idempotently.
3 new tests (now 33 total):
- End-to-end release-group → release resolution with mocked client
- Fallback to direct release lookup when rg lookup misses
- Representative-release picker ranks correctly
Verified against live API with the exact MBID that 404'd for the user
(b88655ba... for DAMN. by Kendrick Lamar): now returns in 1.2s with
the full 14-track listing (BLOOD., DNA., YAH., ELEMENT., FEEL., ...).
Three related fixes to make album/track results look like a real
artist discography instead of a firehose of fan-compiled bootlegs.
1. Drop 'compilation' from the release-group browse primary-type filter.
MB's OR filter (`type=album|ep|single|compilation`) silently breaks
when 'compilation' is included — Metallica drops from 1076 matches
to 82 because `compilation` is a SECONDARY type on MB, not a primary
type. The invalid value corrupts the filter for all types, not just
itself. Now we request `type=album|ep|single` which returns the full
1076; actual compilations (primary=Album + secondary=[Compilation])
are filtered out by the studio-preference logic below.
2. Filter release-groups with non-studio secondary-types
(Live/Compilation/Soundtrack/Remix/Demo/Mixtape/Interview/Audiobook/
Audio drama). For Metallica, the first 100 browse results are 12
studio albums + 83 live bootlegs + 5 compilations — without this
filter the Albums section was dominated by 2019-2021 broadcast
recordings. Falls back to the unfiltered list if filtering leaves
the result set empty (covers live-only niche artists).
3. Sort chronologically ASC by first-release-date. Wikipedia-style
discography ordering — debut album on top, then chronological.
Previous DESC sort put the most recent release on top which, for
prolific artists, meant 2020s material before their classics.
Track side of the same fix:
- Re-orders each recording's `releases` array to put studio releases
first before `_recording_to_track` picks up the first release for
album context. Without this, MB's arbitrary release order often
buried the canonical studio album under random live bootlegs.
- Filters out recordings that only exist on live/compilation release-
groups (keeps the ones with at least one studio release). Falls
back to the full set if the artist has no studio recordings at all.
- Sorts recordings by earliest studio-release year ASC so classic
tracks surface first.
Smoke test against live MB API confirmed:
- Artists: [Metallica score=100]
- Albums: Kill 'Em All (1983) → Ride the Lightning → Master of Puppets
→ ...And Justice for All → Metallica (Black Album) → Load → Reload
→ St. Anger → Death Magnetic → Lulu (2011)
- Tracks: real Metallica recordings (Killing Time, Nothing Else
Matters, Creeping Death, etc.) — a few remastered demos still leak
in where MB metadata quality is thin, but the bulk is correct.
- Total latency: 3.5 seconds.
4 new tests covering the studio filter, live-only fallback, preferred
release ordering, and live-only recording exclusion.
Credit: kettui flagged the poor MB results during PR #371 review.
The previous commit's `browse_artist_recordings` call passed
`inc=releases+artist-credits` — but MusicBrainz's recording browse
endpoint rejects `inc=releases` with HTTP 400. The adapter's error
handler returned an empty list, so the Tracks section stayed empty
even though the fix was supposed to populate it.
Browse without release info is useless for our search UI (tracks
would render with no album), so swap to the fielded Lucene search
`arid:<mbid>` on the `/recording` endpoint. That's the canonical MB
pattern for "find recordings by this artist WITH release context":
- arid: search accepts the artist MBID and returns recordings with
`releases` (release-group, date, media) embedded in each result.
- One API call per lookup, same as browse would have been.
Renamed the method to `search_recordings_by_artist_mbid` so the name
matches its behaviour — it's a search, not a browse. Adapter updated
to call the new name; tests updated to match.
Verified against the live API: Metallica's MBID returns 5 recordings
in ~1.8 seconds (vs the previous 400 error).
Cover Art Archive URLs are deterministic from the MBID: a GET either
307-redirects to the image or returns 404. The previous adapter fired
`requests.head(timeout=3)` per search result to probe for the image
first. 10 results × 3s worst-case = up to 30s of blocking HEAD calls
before a search returned.
The probe was defensive overhead — the frontend already handles 404 via
`<img onerror>` fallback. Building the URL deterministically and letting
the browser load it lazily collapses the tail latency to the real MB API
calls (artist-search + browse = ~3s at the 1-rps rate limit).
Also prefer release-group scope over per-release scope when both are
available — release-group covers every edition of an album, so the hit
rate is noticeably higher than pinning to a specific regional release.
Removes now-unused `self._art_cache` and the `requests` import.
Bare name queries (typing 'metallica') now resolve to an artist MBID via
the fuzzy search added in the previous commit, then BROWSE that artist's
release-groups and recordings instead of text-searching release/recording
titles. That's the only way to fix the core garbage-results issue: MB
indexes release/recording titles, not artist names, so 'recording:metallica'
matches random tracks literally titled 'Metallica' (all scoring 100).
Structure:
- `_split_structured_query` — detects 'Artist - Title' / 'Artist – Title' /
'Artist — Title' shapes. When present, text-search is correct (user
gave an explicit title to match).
- `_resolve_top_artist` — memoized per-instance lookup for the top-scoring
artist MBID. Backend fires artists/albums/tracks searches in parallel
against one shared client instance, and albums+tracks both need the
same artist lookup. Cache + lock means one HTTP call instead of three.
- `_release_group_to_album` / `_recording_to_track` — shared projection
helpers between the browse and text paths so both paths return the
same dataclass shape.
Search flow per kind:
- `search_albums('metallica')` → resolve top artist → browse release-groups
with `type=album|ep|single|compilation` → sort by type priority then
release date desc → Album dataclasses for top N.
- `search_tracks('metallica')` → resolve top artist → browse recordings
with `inc=releases+artist-credits` → dedupe by normalized title (MB
has many live/compilation variants of the same song) → sort by release
date desc → Track dataclasses for top N.
- `search_albums('foo - bar')` → structured query → text-search path
(unchanged behavior, now score-filtered to 80+).
- `search_tracks('foo - bar')` → same.
- Both text-search paths also dedupe through `_search_albums_text` /
`_search_tracks_text` helpers, which apply the 80-score filter that
the artist-first path gets free from the resolver's threshold.
Also dedupes text-path tracks through the new `_recording_to_track`
helper, replacing ~60 lines of inline projection code. Net change is
more lines overall (browse + helpers) but the text paths shrank and
the garbage-results issue is fixed.
Credit: kettui flagged the missing Artists section + unusable track
results during PR #371 review.
`MusicBrainzSearchClient.search_artists` has been a `return []` stub
since the feature landed, with a comment claiming the MB tab 'doesn't
show artists.' That's why kettui saw a missing Artists section on the
search page — not a missing render, a hardcoded empty list.
Re-enable it properly:
- New `strict=False` parameter on `MusicBrainzClient.search_artist`
sends a bare Lucene query instead of `artist:"..."`. MusicBrainz
matches bare queries against alias+artist+sortname indexes together,
which is the right behavior for user-facing fuzzy search (finds
typos, aliases, sortname variants). `strict=True` remains the
default for enrichment/AcoustID callers that want exact matches.
- Adapter filters results to `score >= 80`. MB assigns a 0-100 Lucene
score on every hit; the true artist + close variants score 100,
tribute bands and lookalikes typically land in the 40-65 range.
The cutoff keeps "Metallica" (100) and drops "Black Metallica
Tribute Band" (60) without hand-curated lists.
- Results returned as the same `Artist` dataclass used elsewhere in
the search-tab adapter layer. `popularity` carries the MB score
(0-100) so the frontend can sort/highlight top matches if desired.
Add `browse_artist_release_groups(mbid)` and `browse_artist_recordings(mbid)`
to MusicBrainzClient. These hit `/ws/2/release-group?artist=<mbid>` and
`/ws/2/recording?artist=<mbid>` respectively — the correct MusicBrainz
pattern for "give me everything linked to this artist."
Why this matters: our current search adapter calls text-search
(`release?query=...` / `recording?query=...`) for albums and tracks,
which matches entity titles literally. Typing "metallica" hits unrelated
releases titled "Metallica" and recordings named "Metallica" by obscure
bands — every garbage match scores 100 because they're all exact title
matches on the wrong field.
Browse walks the artist→release-group and artist→recording links
directly. Once we know the artist's MBID (from `search_artist`), browse
returns their actual discography instead of title collisions.
No behavior change yet — search adapter still uses the old path. Follow-
up commit wires the new endpoints in.
Reference: https://musicbrainz.org/doc/MusicBrainz_API — "Browse queries
retrieve entities linked to a known entity" vs search.
MusicBrainz mandates a meaningful User-Agent with contact info, warning
that bare strings can trigger IP blocking under load. Our client was
sending `SoulSync/2.3` with no contact — and the search adapter passed
an app version hard-coded at "2.3" that's now stale (UI is at 2.40).
Fix: default contact to the project URL (`https://github.com/Nezreka/SoulSync`)
when no email is supplied, so every request lands as
`SoulSync/<version> ( https://github.com/Nezreka/SoulSync )`. Drop the
search-adapter version suffix to a generic "2" since the exact UI minor
version would add noise to every MB request without helping operators
track issues.
Reference: https://musicbrainz.org/doc/MusicBrainz_API — "it is
important that your application sets a proper User-Agent string."
JohnBaumb's review: "If we're going to refactor the web_server.py soon,
might as well start moving stuff away from web_server.py in our PRs.
_build_source_only_artist_detail, make it a module, it's perfect."
This continues the pattern the prior commit started with the source-ID
lookup helpers: move the pure data-building logic to a side-effect-free
core module, leave a thin wrapper in web_server.py that bridges the
Flask response and the module-global clients.
**core/artist_source_detail.py** — pure function that takes the artist id,
name, and source plus dependency-injected per-source clients (spotify,
deezer, itunes, discogs) and a Last.fm API key. Returns
(payload_dict, http_status) so it isn't coupled to Flask.
**web_server.py wrapper** — builds the client bag from the module globals
(checks Spotify auth, constructs the Discogs client from the configured
token, reads the Last.fm API key) and wraps the core return in jsonify.
147 lines of logic go away from web_server.py; the 24-line wrapper is
purely glue.
**tests/test_artist_source_detail.py** — 21 focused tests covering the
response envelope, the source-specific ID-field stamping for all six
supported sources, the dedup_variants=False contract (the behaviour
that originally motivated the split of MetadataLookupOptions), per-source
genre/follower extraction with safe handling of missing or throwing
clients, and the Last.fm enrichment branch including the no-key and
error-path cases. Runtime 0.26s.
Cin observed that database/api_call_history.json was occasionally
landing on disk truncated mid-write — `_load()` would log
`History file is not valid JSON, starting fresh` and 24h of metrics
would be lost.
Root cause: `save()` opened the file in 'w' mode (which truncates to
0 bytes immediately) and then streamed JSON via `json.dump`. Any
SIGINT/SIGTERM/crash between truncate and final write left the file
half-formed — exactly Cin's symptom of the JSON cutting off mid-array.
Switch to the standard atomic pattern: write to a sibling .tmp file,
flush + fsync, then `os.replace` (atomic on every platform we run on).
Failed writes also clean up the leftover .tmp file. The canonical
file is now either the previous good copy or the new good copy —
never a partial one.
Cin's review note: typing artist_name as plain `str` forced callers
that didn't have a name to pass `""` as a placeholder, which leaks the
parameter's emptiness contract into every call site and reads badly in
tests. Switching to `Optional[str] = None` lets callers omit it.
The function body's `if artist_name and active_server:` check already
handles None and "" identically, so no body changes were needed. Tests
that previously passed `artist_name=""` drop the argument; one new test
covers the omitted-arg path explicitly.
The web_server.py wrapper takes the same default for symmetry.
Cin pointed out that the prior version of test_artist_source_lookup.py
AST-parsed web_server.py to verify a constant and to string-match a
function's response keys. That was a workaround for the fact that
web_server.py can't be imported at test time (it boots Spotify,
Soulseek, Plex, etc.) — the right answer is to move the logic into a
side-effect-free module so it can be imported and tested directly.
This commit:
- adds core/artist_source_lookup.py containing the SOURCE_ID_FIELD
map, the SOURCE_ONLY_ARTIST_SOURCES set, and find_library_artist_for_source
- replaces the inline definitions in web_server.py with imports +
a thin wrapper that injects the active media server
- rewrites the tests to import from the core module directly:
* mapping correctness is now a plain equality assertion
* lookup behaviour is exercised against a real MusicDatabase
* the AST parse and the string-matching contract test class are
gone
- drops the _build_source_only_artist_detail contract test entirely
(the weakest of the four — it was just string-matching the function
body); when that function moves to core/ it can get a real
behavioural test alongside.
Test runtime drops from ~161s to ~5.8s. All 18 tests pass.
Source artists landing on /artist-detail were rendering an almost-blank
hero — image + name + a tiny Download button — because the backend
response only had {id, name, image_url, server_source: null, genres: []}.
The library.js renderers do their best with what they have, and that
wasn't much.
Backend changes (_build_source_only_artist_detail):
- Set the source-specific ID field (deezer_id / spotify_artist_id /
itunes_artist_id / discogs_id / soul_id / musicbrainz_id) on
artist_info so the corresponding service badge renders on the hero.
- Try the source's own get_artist_info / get_artist for genres +
followers (Spotify always; Deezer/iTunes/Discogs when available).
Spotify also fills image_url if metadata_service.get_artist_image_url
came up empty.
- Last.fm enrichment by artist name — bio + listeners + playcount +
lastfm_url. Mirrors what library artists get from the cached
enrichment workers but on demand for source artists.
- All enrichment lookups are wrapped in try/except so a 500 from any
one source doesn't break the whole response.
Frontend (library.js populateArtistDetailPage):
- Watchlist button now initialises for source artists too. Falls back
to artist.id + artist.name when there's no canonical Spotify
identity (which is the common case for non-library artists).
Discography dedup opt-out:
- Added dedup_variants flag to MetadataLookupOptions (default True so
library artists are unchanged). Source-only path now passes
dedup_variants=False so every "Deluxe Edition" / "Remastered" /
"Anniversary" variant the source returns is shown — matches the
inline /artists page behaviour the user was comparing against.
Result: source artists' hero now shows badges + bio + listeners +
playcount + watchlist button + genres in addition to image and name.
Discography lists every release the source returns, not the deduped
canonical view.
User reported searching "Maduk - Leave A Light On" on Tidal silently
downloaded Tom Walker's completely different song of the same name, then
embedded Maduk's metadata into Tom Walker's audio. Three layers of
defense all failed permissively. Two of them are fixed here; the third
(score formula weights) was left alone since these two together cover it.
Layer 1 fix — candidate artist gate (web_server.py:27782)
Old: `if _best_artist < 0.4 and confidence < 0.85: continue`
New: `if _best_artist < 0.5 and confidence < 0.85: continue`
SequenceMatcher returns exactly 0.400 for "maduk" vs "tom walker"
(5-char vs 10-char strings with coincidental char matches), which
slipped past the strict `< 0.4` check. The word-boundary containment
check earlier in the function already short-circuits legitimate
formatting variations to sim=1.0, so falling to SequenceMatcher means
strings are genuinely different. 0.5 closes the fencepost AND gives
a small safety buffer.
Layer 3 fix — AcoustID verification (acoustid_verification.py:316)
When title matches but artist doesn't AND expected artist isn't found
anywhere in AcoustID's returned recordings:
Old: always SKIP (let file through, assume cover/collab)
New: FAIL if artist_sim < 0.3 (clear mismatch)
SKIP if artist_sim >= 0.3 (ambiguous — cover/collab/formatting)
The 0.3 cutoff catches hard mismatches like Maduk/Tom Walker (sim ~0.2)
while preserving benefit-of-the-doubt for borderline artist formatting
differences. Legitimate covers and collabs where the expected artist
appears anywhere in AcoustID's recordings still PASS via the existing
secondary-match loop above.
Both fixes are defense-in-depth — either alone would have caught this
bug. Together they close the pre-download AND post-download gaps.
All 292 tests pass. Version bumped to 2.39 with changelog entries.
Tidal's search engine chokes on long queries with multiple qualifier
words (remix credits, edit labels, bonus-disc markers). User reported
case: "maduk transformations remixed fire away fred v remix" returns 0,
but shortening to "maduk transformations remixed fire away" works.
Behaviour change:
- On a 0-result search, retry with progressively-shortened variants
(capped at 5 total attempts, 100ms pause between).
- Variants (in priority order):
1. strip trailing "(...)" / "[...]"
2. strip all parentheticals/brackets
3-5. drop last 1 / 2 / 3 tokens
6. keep first half of tokens (rounded up)
- Dedupes so identical variants don't re-query.
Safety — qualifier-aware filter:
- Variant keywords (Live / Remix / Acoustic / Extended / Unplugged /
Instrumental / Karaoke / etc.) are extracted from the original query
using word-boundary match so "edit" doesn't match "edition" and
"mix" doesn't match "remixed".
- If the original query carries any qualifiers, fallback results MUST
contain those qualifiers in their track names — otherwise a shortened
query could silently downgrade "Song (Live)" to the studio "Song".
- Tracks that fail the filter are dropped. If no variant produces
qualifier-matching tracks, returns ([], []) — the same outcome as the
original code, so no regression.
Contract preservation:
- Never raises to caller (outer try/except catches orchestration errors).
- Returns ([], []) on any failure path, same as original.
- Original-query successes take the same code path as before — no
behavioural change for queries that already work.
- Defensive guards for None/empty/non-string query (early return).
Logging:
- Preserves original warning/error/info messages for back-compat log
scraping.
- Adds fallback-success INFO log ("Tidal fallback query succeeded: ...")
so successful retries are visible in production logs.
- Adds qualifier-filter INFO/DEBUG logs with kept/total counts.
- Per-attempt exception logs at DEBUG (not ERROR) to avoid noise when
retries succeed.
- Traceback preserved on final failure.
Tests (16 regression tests in tests/test_tidal_search_shortening.py):
- Skowl's reported query reaches his working variant within the cap.
- Paren/bracket stripping priority.
- Short queries produce no variants.
- All variants unique (dedup guard).
- Progressive token drops present for long queries.
- Qualifier extraction is word-bounded (no "edit" in "edition").
- Qualifier extraction is case-insensitive.
- Track name filter requires ALL qualifiers.
- Empty-qualifier list passes every track (original-query behaviour).
All 292 tests pass.
New smart template variable that emits "CD01" / "CD02" etc. in filenames
on multi-disc albums, and expands to empty string on single-disc albums
so mixed libraries don't end up with "CD01" on every single.
Template behaviour:
- total_discs > 1 -> "CD{disc:02d}" (zero-padded, CD prefix)
- total_discs <= 1 -> empty string
- Both $cdnum and ${cdnum} bracket form supported
- Empty value collapses cleanly via existing double-dash regex plus new
leading-dash cleanup pass
Wiring:
- _apply_path_template in web_server.py (download pipeline)
- _apply_path_template in core/repair_jobs/library_reorganize.py
(Reorganize repair job)
- total_discs added to every album-mode template context:
* download pipeline album branch (uses resolved total_discs even for
single-track downloads from search)
* per-album Reorganize preview + apply endpoints (pre-scan all track
tags once, take max disc_number)
* Library Reorganize repair job (already had album_total_discs map,
just added to context dict)
Leading-dash cleanup added to _get_file_path_from_template (web_server)
and _build_path_from_template (library_reorganize) so templates like
"$cdnum - $track - $title" don't leave "- 05 - Title" on single-disc
albums.
UI:
- Template hint in Settings -> File Organization documents $cdnum
- Template validation variable list includes $cdnum
- Reorganize modal variable reference shows $cdnum with example "CD01"
Verified:
- Multi-disc disc 1 -> "CD01 - 05 - Track"
- Multi-disc disc 2 -> "CD02 - 05 - Track"
- Single-disc -> "05 - Track" (no leading dash)
- Templates without $cdnum behave unchanged
- 276/276 tests pass
Two bugs reported in issue #320:
1. Auto-watchlist scan bypassed Global Override settings.
scan_watchlist_profile applied _apply_global_watchlist_overrides, but
the scheduled auto-scan called scan_watchlist_artists directly —
bypassing the override. Users who unchecked "Albums" or "Live" under
Watchlist → Global Override still saw full albums and live tracks
added during nightly scans (per-artist defaults, which include
everything, won).
Moved override application into scan_watchlist_artists itself so
every entry point respects it. scan_watchlist_profile now forwards
the apply_global_overrides flag through to avoid double-application.
2. is_live_version (watchlist + discography backfill) and
live_commentary_cleaner's content patterns used bare \blive\b, which
matched verb uses like "What We Live For" by American Authors,
"Live Forever" by Oasis, "Live and Let Die" by Wings.
Tightened the live patterns to require clear recording context:
(Live) / [Live Version] / - Live / Live at|from|in|on|version|
session|recording|performance|album|show|tour|concert|edit|cut|take
/ In Concert / On Stage / Unplugged / Concert.
Locked in 11 regression tests covering the reported false positives
(What We Live For, Live Forever, Living on a Prayer, Live and Let Die)
and the reported true positives (Dimension - Live at Big Day Out,
MTV Unplugged, etc.).
Version bumped to 2.37 with changelog entries.
Root-cause fix for "scanning 50 artists" then silence: when the master
repair worker was paused, force-run still kicked off _run_job but the
job's first wait_if_paused() blocked forever because is_paused was tied
to the master-enabled state. Force-run now bypasses master-pause —
scheduled runs still respect it.
Also fixes Fix All on discography findings doing nothing: the backend
bulk_fix_findings query had a fixable_types allowlist that excluded
missing_discography_track (and acoustid_mismatch). Added both.
Backfill job rebuild:
- auto_add_to_wishlist opt-in setting — creates findings AND pushes to
wishlist during the scan
- 3-option fix dialog (Add to Wishlist / Just Clear / Cancel) on single
Fix, Bulk Fix selection, and Fix All (page-level)
- Fix All "Just Clear" path uses the clear endpoint with job_id filter
instead of the generic "may delete files" bulk-fix warning
- Batched in-memory matching using get_candidate_albums_for_artist +
get_candidate_tracks_for_albums (same fast path the Library pages use)
- Rich album context per finding (id, name, album_type, release_date,
images, artists, total_tracks) — flows through the wishlist pipeline
so auto-processor classifies each track into the right cycle
(albums vs singles) and post-processing gets correct folder/tags/art
- Per-artist progress logs [N/50] Scanning ArtistName
- Default interval 24h (was 168h); all release types default on; settings
reordered with _section_* group headers (Core / Release Types /
Content Filters)
Repair settings UI:
- Generic _section_<name> key convention renders as an uppercase group
divider in the settings panel — any job can opt in
- .repair-setting-row gets a dashed bottom border so label↔toggle pairing
is visually clear
- _prettifyRepairSettingKey fixes acronym capitalization (EPs, not Eps)
Version bumped to 2.36 with changelog entries.
Two bugs kept this job from finding anything useful on a typical library.
1. Wrong Deezer column name. The artists table has a deezer_id column
(per music_database.py:1986), but the job looked for deezer_artist_id
in both _scan_artist (line 132) and _get_library_artists (line 345).
For Deezer-primary users, this meant the Deezer ID never made it into
the source_ids map, so get_artist_discography fell back to artist-
name-only search — slower and less accurate than an ID lookup.
2. Spotify-reported EPs were silently excluded. Spotify lumps EPs and
true singles under album_type='single'. The previous
_should_include_release short-circuited on album_type='single' and
returned the include_singles setting (default False), so 4-6 track
EPs on Spotify-primary libraries never survived the filter — even
though include_eps defaulted to True. Only 7+ track full albums
made it through. This is the main reason users felt the job did
nothing.
Fixes:
- Use the correct deezer_id column name in both reference sites.
- Restructure _should_include_release so only 'album', 'ep', and
'compilation' are trusted outright. Anything else (including
'single' and missing type) falls through to a track-count
disambiguation matching the download pipeline's _get_album_type_display:
1-3 tracks = true single, 4-6 = EP, 7+ = album. A Spotify-returned
'single' with 5 tracks now correctly counts as an EP.
Full suite stays at 263 passed. Ruff clean.
PR #340 added ruff to the build-and-test.yml CI gate, which surfaced
286 pre-existing lint errors. Left unfixed, every feature branch push
fails CI. This commit resolves all of them so CI goes green and
contributors can actually land work.
Auto-fixes (248 of 286): removed unused f-string prefixes (F541),
renamed unused loop control variables with underscore prefix (B007),
removed duplicate imports (F811).
Manually fixed 10 latent bugs ruff caught (all wrapped in try/except
today, silently failing):
- music_database.py: _add_discovery_tables() called undefined
conn.commit() — would have crashed the iTunes-support migration
for existing databases. Now uses cursor.connection.commit().
- web_server.py settings GET: referenced undefined download_orchestrator
when it should be soulseek_client. Feature (_source_status on the
settings payload) was silently missing for UI auto-disable logic.
- web_server.py _process_wishlist_automatically: active_server
undefined in track-ownership check. Auto-wishlist was falling
through to the error handler and re-downloading owned tracks.
- web_server.py start_wishlist_missing_downloads: same active_server
bug in the manual wishlist path.
- web_server.py _process_failed_tracks_to_wishlist_exact: emitted
wishlist_item_added automation event with undefined artist_name
and track. Automation event silently never fired correctly.
- web_server.py discovery metadata enrichment: referenced cache
without calling get_metadata_cache() first. Track enrichment from
cached API responses was silently skipped.
- web_server.py Beatport discovery worker: wing-it fallback branch
used undefined successful_discoveries variable. Wing-it counter
never incremented correctly. Now uses state['spotify_matches']
consistently with the rest of the function.
- web_server.py _run_full_missing_tracks_process: stale import json
mid-function shadowed the module-level import, making an earlier
json.dumps() call reference an unbound local (F823).
- web_server.py discovery loop: platform loop variable shadowed
the module-level platform import (F402).
- core/watchlist_scanner.py: 7 lambda captures of loop variables
(B023 classic Python closure-in-loop bug) now bind at creation.
No existing tests had to change. Full suite stays at 263 passed.
- 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
If the application was using a non-standard location for app.log, the other logs would still go to the default location. Now everything goes under the same, configured folder
When staging files are organized as Artist/Albums/AlbumFolder or
Artist/AlbumFolder, the auto-import now uses the parent folder name
as the artist instead of trusting embedded file tags.
Uses relative path from staging root to determine folder depth, so
albums directly in staging root don't accidentally pick up container
paths as artist names. Common category subfolder names (Albums,
Singles, EPs, Mixtapes, etc.) are recognized and skipped.
Fixes mixtapes and compilations where file tags have DJ names or
incorrect artists (e.g. files tagged as "Slim" in a 2Pac folder).
New repair job that scans each artist in the library, fetches their
full discography from metadata sources, and creates findings for any
tracks not already owned. Users review findings and click "Add to
Wishlist" to queue missing tracks for download.
Respects content filters (live/remix/acoustic/instrumental/compilation)
and release type filters (album/EP/single). Opt-in, disabled by default,
runs weekly, processes up to 50 artists per run with rate limiting.
Jobs with interval_hours set to 0 caused ZeroDivisionError in
_pick_next_job staleness calculation. Now skips jobs with invalid
(zero or negative) intervals.
The Subsonic getArtist endpoint doesn't support musicFolderId filtering,
so when an artist exists in multiple libraries, all their albums were
imported regardless of which music folder was selected in settings.
Now passes musicFolderId to getArtist (in case Navidrome supports it),
and as a fallback filters albums against a cached set of album IDs
built from getAlbumList2 (which reliably supports musicFolderId).
The set is built once per session and invalidated on folder change.
The high-confidence fingerprint skip (≥0.95) assumed title mismatches
were language/script differences and bypassed verification. But a high
fingerprint score just means AcoustID identified the audio confidently —
not that it matches the requested track. Now requires partial title
(≥0.55) or artist (≥0.60) similarity before skipping, so completely
wrong files (e.g. different song/artist from same remix producer) are
correctly rejected.
- 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
iTunes API can return collection metadata without song tracks for
region-restricted albums. The _lookup fallback only checked if results
was empty, so a collection-only response was accepted and cached as
{'items': []}. All future lookups returned the cached empty result.
Three fixes:
- get_album_tracks now checks for actual song items and tries fallback
storefronts when only collection metadata is returned
- Skip cached results with empty items array (prevents stale cache hits)
- Backend returns descriptive 404 error, frontend surfaces it in toast
Fixed 5 critical gaps in the download orchestrator where lidarr was
missing from client loops: get_all_downloads, get_download_status,
cancel_download fallback, clear_all_completed_downloads, and
cancel_all_downloads. Without these, lidarr downloads were invisible
to the UI, couldn't be cancelled, and accumulated in memory.
Also: error messages now visible in download list (appended to
filename on error state), removed "(Development)" label from UI.
- 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
The retag fix for AcoustID mismatches was only updating the DB
record (title, artist_id) without writing corrected tags to the
actual audio file. Users would click Fix, the finding disappeared,
but the file on disk stayed unchanged. Now writes title and artist
tags to the file via Mutagen after the DB update.
Also fixed artist INSERT missing server_source when creating a new
artist during retag — now uses the active media server value.
The listening stats worker ran three N+1 query patterns on every
30-minute poll cycle:
1. _resolve_db_track_id was called once per history event (up to
500 events = 500 SELECTs).
2. _map_play_counts_to_db ran one SELECT per server track ID.
3. _enrich_stats_items ran one SELECT per top_artist, top_album,
and top_track (typically 60 extra queries per rebuild).
All three paths now use batched IN queries with 500-row chunks
(well under SQLite's default variable limit of 999). Case-insensitive
matching and LIMIT 1 semantics are preserved via setdefault() on the
Python-side result dict.
Track resolution uses SQLite row-value IN ((?,?), ...) on
(LOWER(title), LOWER(artist_name)), available in SQLite 3.15+
(bundled with Python 3.13).
Four enrichment workers (Last.fm, MusicBrainz, Tidal, Qobuz) had a
bug where every background loop re-processed the same rows because
the existing-ID short-circuit path never set match_status, and two
workers queried the wrong column when checking for an existing ID.
lastfm_worker._get_existing_id queried a non-existent lastfm_id
column; the real column is lastfm_url. The method now reads
lastfm_url for all three entity types.
musicbrainz_worker._get_existing_id queried musicbrainz_id for all
entity types, but albums use musicbrainz_release_id and tracks use
musicbrainz_recording_id. The method now uses a per-type column map.
All four workers (lastfm, musicbrainz, tidal, qobuz) now write
match_status='matched' when they short-circuit on an already-present
external ID, so these rows are no longer re-selected on the next
worker sweep.
A new migration (_backfill_match_status_for_existing_ids) runs once
on startup to retroactively set match_status='matched' for rows that
already have an external ID but NULL match_status. This covers legacy
data, manual matches, and rows populated from file tags outside the
worker.
MetadataCache.get_search_results previously looped over each cached
entity ID and issued one SELECT per ID, producing N extra queries per
cached search hit. It now resolves all entities in a single batched
IN query (chunked at 500 to stay under the SQLite variable limit),
then reconstructs the result list in the original result_ids order
using an in-memory dict lookup.
- 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.
When no cached token exists, spotipy's auth probe starts an interactive
OAuth flow that binds 127.0.0.1:<redirect_port> inside the container.
This either steals Flask's port 8008 (crash loop) or binds loopback-only
on 8888 (unreachable from Docker host — 'connection reset by peer').
Now checks for a cached token before probing. If none exists, returns
False immediately so users authenticate via the SoulSync web UI instead.
No behavior change for already-authenticated users.
Fixes#269
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.
The Duplicate Detector repair job had its own ignore_cross_album setting
that was independent of the global allow_duplicate_tracks setting. When
a user enabled 'Allow duplicate tracks across albums', the detector
still flagged same-titled tracks on different albums as duplicates.
Now respects the global setting — if duplicates are allowed, cross-album
matches are always skipped.
Users can now override which metadata provider (Spotify, Deezer, Apple Music,
Discogs) is used when scanning a specific watchlist artist for new releases.
The selector appears in the artist config modal and only shows sources the
artist has enrichment IDs for. Default behavior is unchanged — all artists
use the global metadata source unless explicitly overridden.
The redownload branch had `import json, uuid` locally inside the function,
which caused Python to treat `uuid` as a local variable for the entire
function scope. When the retag branch ran instead, `uuid` was unbound.
Both modules are already imported at the top of the file.
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.
New MusicBrainz tab in Enhanced and Global search — finds tracks and
albums on MusicBrainz's community database with Cover Art Archive
images. Covers obscure tracks that Spotify/Deezer/iTunes miss.
- core/musicbrainz_search.py: search adapter with Track/Artist/Album
dataclasses, Cover Art Archive integration, smart query parsing
- Albums deduplicated (keeps best version with date and art)
- No artist results shown (MusicBrainz has no artist images)
- Album detail with full tracklist for download modal
- Smart word-boundary splitting for queries without separators
- Global search results container widened from 620px to 920px
- UI version bumped to 2.32
Files with embedded tags (artist+title from post-processing) were
failing import because the metadata search scored low (66%) and the
AcoustID result returned before the tag-preference code could run.
- Tag-based identification now returns 85% confidence when embedded
tags have an artist field, borrowing album art from weak metadata
- AcoustID search result only accepted at 80%+ confidence, otherwise
kept as fallback (doesn't short-circuit past tag preference)
- AcoustID None artist/title falls back to tag data via 'or' operator
- Stop retrying failed/unidentified items every scan cycle
Items with status needs_identification, failed, or rejected were not
in the skip list, causing them to be re-scanned and re-logged every
60 seconds indefinitely. Now skips all terminal statuses.
New 'soulsync' media server option manages the library directly from
the filesystem, bypassing Plex/Jellyfin/Navidrome entirely.
Two paths populate the library:
1. Downloads/imports write artist/album/track to DB immediately at
post-processing completion, with pre-populated enrichment IDs
(Spotify, Deezer, MusicBrainz) so workers skip re-discovery
2. soulsync_client.py scans Transfer folder for incremental/deep scan
via DatabaseUpdateWorker (same interface as server clients)
New files:
- core/soulsync_client.py: filesystem scanner implementing the same
interface as Plex/Jellyfin/Navidrome clients. Recursive folder scan,
Mutagen tag reading, artist/album/track grouping, hash-based stable
IDs, incremental scan by modification time.
Modified:
- web_server.py: _record_soulsync_library_entry() at post-processing
completion, client init, scan endpoint integration, status endpoint,
web_scan_manager media_clients dict, test-connection cache updates
- config/settings.py: accept 'soulsync' in set_active_media_server,
get_active_media_server_config, is_configured, validate_config
- core/web_scan_manager.py: add soulsync to server_client_map
Dedup: checks existing artist/album by name across ALL server sources
before inserting to avoid duplicates. Enrichment IDs only written when
the column is empty (won't overwrite existing data).
Race condition: scanner re-scanned folders while post-processing was
still moving files, causing partial matches and ghost failures. Now
tracks in-progress paths and skips them on subsequent scans.
Coverage penalty fix: individual tracks that match at 80%+ confidence
now auto-import even when overall album coverage is low (e.g. 2 of 18
tracks present). Previously low coverage killed the entire import.
Import page: stats bar, filter pills, Scan Now, Approve All, Clear
History (clears imported + failed), live scan progress.
- Track numbers defaulted to 1 instead of using metadata source values
- Release dates not captured, causing missing year in path templates
- Cover art missing for Deezer (direct image_url not checked)
- Track names in expanded view showed Unknown (wrong JSON field name)
- Read year/date from embedded file tags as fallback
- Add Deezer get_album_metadata/get_album_tracks fallbacks
- Handle Deezer tracks.data response format
Loose audio files in the staging root are now picked up alongside album
folders. Singles are identified via embedded tags, filename parsing
(Artist - Title.ext), or AcoustID fingerprinting, then matched against
the configured metadata source. Confidence-gated processing applies
the same way as album folders (90%+ auto, 70-90% review, <70% manual).
Soulseek results from "Various Artists", "VA", "Unknown Artist", and
"Unknown Album" folders are now rejected before scoring. These
compilation folders rarely contain properly tagged files for the target
artist.
Clearing the wishlist now also cancels any active wishlist download
batch and resets the auto-processing flag, so downloads don't keep
running after the source tracks are removed.
Priority 0 query (artist + album + title) was gated behind a download
mode check that excluded Soulseek, the source that benefits most from
it. Soulseek searches match against file paths where users organize as
Artist/Album/Track — without the album name, ambiguous artist names
could match wrong-artist results (e.g. "Bleakness" as an album folder
instead of an artist). Removed the mode gate so all sources get the
most specific query first.
Repair-worker album fills now generate explicit track IDs when copying rows, instead of relying on SQLite auto-assignment that no longer exists for TEXT primary keys. The unknown-artist fixer now does the same for new artists.
Also add a regression test for the album-fill copy branch and keep the AcoustID scanner resilient to legacy null-ID rows.
Full auto-import pipeline: background worker watches the staging folder,
identifies music using embedded tags → folder name parsing → AcoustID
fingerprinting, matches files to metadata source tracklists, and
processes high-confidence matches through the existing post-processing
pipeline automatically.
Worker: AutoImportWorker with start/stop/pause/resume, configurable
scan interval (default 60s), confidence threshold (default 90%), and
auto-process toggle. Processes one folder per cycle, alphabetical
order. Disc folder detection, stability checking, content hash dedup.
Confidence gate: 90%+ auto-processes silently, 70-90% queued as
pending review with approve/dismiss actions, <70% flagged for manual
identification. Track matching uses weighted algorithm (title 45%,
artist 15%, track number 30%, album tag 10%).
Database: auto_import_history table tracks every scan result with
folder hash, match data JSON, confidence, status, timestamps.
API: 7 endpoints — status, toggle, settings (GET/POST), results
(filtered/paginated), approve, reject.
UI: Auto tab on Import page with enable toggle, confidence slider,
scan interval selector. Live result cards with album art, confidence
bar (green/yellow/red), status badges, match stats. 5-second polling.
Switch similar-artist backfill to the shared provider-priority flow instead of assuming iTunes as the fallback.
Reuse the generic metadata search helpers, keep a compatibility alias for the old helper name, and update the scanner tests to cover the new path.
Add a regression test that verifies backfill walks each available fallback provider and persists the resolved IDs per source.
Shift similar-artist lookup to the shared metadata provider priority flow.
Use generic provider clients for search and metadata extraction instead of
branching on Spotify/iTunes-specific paths.
Add a regression test that verifies MusicMap matching queries the provider
priority list and preserves canonical metadata from the best match.
Make discovery pool population and curated playlists follow the configured metadata source order. Keep Spotify strict where fallback would corrupt source-specific IDs, and trim fan-out with smaller similar-artist samples and page caps. Leave the remaining incremental path for follow-up.
Reduce request volume in the discovery helpers while keeping the source-priority model intact.
- make cache_discovery_recent_albums source-priority aware
- cap Spotify artist-album pagination in the discovery and incremental paths
- reduce the similar-artist sample size for the cache-refresh helper
- keep Spotify strict where fallback would contaminate source-specific IDs
- add regression coverage for source order, strict Spotify lookups, and pagination caps
Watchlist scanner: empty discography (no new releases in lookback) was
treated as API failure, causing "Failed to get artist discography" for
artists like Kendrick Lamar who simply had no recent releases. Now
distinguishes None (API failure → try next source) from [] (success,
no new tracks). Spotify backfill now uses the authenticated client
instance instead of creating a fresh unauthenticated one.
Wishlist nebula: album remove now sends album_name (API updated to
accept album_name as fallback alongside album_id). Track remove
re-renders the nebula after deletion. Toned down processing pulse
animation.
Updated test to verify fallback triggers on API failure (None), not
on empty results.
Replaced track-count-only release selection with deterministic scoring
across 6 factors: track count match (40pts), release status (10pts),
country preference with US/worldwide bias (10pts), format preference
favoring Digital/CD over Vinyl/Cassette (10pts), barcode presence (3pts),
and date completeness (2pts). Same inputs always produce the same release.
Also fixed critical bug: _embed_source_ids was missing the context
parameter, silently skipping ALL source ID tag embedding since the
MusicBrainz consistency commit. Now passes context from the caller.
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
Rewrote the AcoustID scanner job to scan all library tracks (via DB file
paths resolved to disk) instead of only the Transfer folder. Checkpoints
by track ID for robust resume across restarts. Defaults changed to
enabled, 24h interval, batch size 200.
Added _fix_acoustid_mismatch handler with three actions:
- retag: update DB title/artist to match actual audio content
- redownload: add expected track to wishlist and delete wrong file
- delete: remove wrong file and DB record
This catches cases like a file tagged as "Dinosaur Bones" that is
actually "Helicopters" — the scanner fingerprints the audio, detects
the mismatch, and the user can fix it from Library Maintenance findings.
Resolve Spotify artist matching through the exact Spotify client only, so watchlist ID backfill cannot drift to fallback-provider results. Remove the remaining preemptive provider availability check from the backfill loop.
Allow cached Spotify search results to return even when Spotify is rate-limited or temporarily unavailable, and remove redundant rate-limit gating after auth checks.
Drop the old active-provider artist lookup helpers from watchlist_scanner now that the web scan flow resolves sources through the shared metadata priority.
Keep the Spotify-specific feature toggles in place for discovery and sync paths that still use them.
Move the web watchlist scan core onto the shared metadata source priority so primary provider settings are respected during artist, album, and image resolution.
Add coverage for primary-source-first discography lookup and fallback to later providers when the primary source has no albums.
Bring placeholder tracklist skipping back into the shared watchlist scan path, and centralize the DB-only artist image backfill helper so both web scan entrypoints reuse the same logic.
Drop the legacy watchlist scan entrypoints that are no longer used by the web scan flow, and keep the live refresh path pointed at the shared scanner helper.
Move the shared watchlist scan loop into core/watchlist_scanner.py so web_server.py only handles triggers, locks, progress, and post-scan orchestration.
Manual and scheduled watchlist scans now share the same scanner-side core, while the web entrypoints keep profile selection and automation progress updates.
Two-layer detection: (1) check the Qobuz API response for sample=True
before downloading, and (2) validate actual file duration with mutagen
after download — if under 35 seconds, delete and return None. Qobuz
returns valid audio files for previews (~2-5MB FLAC) that pass the
existing 100KB size check, so duration is the reliable signal.
