Users manually match an album to the regular edition, but enrichment/
repair keeps treating it as the deluxe (missing songs, renumbered tracks).
Root cause: an album has TWO identities — the enrichment match
(spotify_album_id, which manual-match sets and the worker already honors)
and a SEPARATE canonical version pin (canonical_album_id, added by #777).
The canonical pin is what track-number repair / reorganize / missing-track
detection actually read, and library_manual_match never wrote it — so it
was resolved independently and landed on the deluxe edition.
(So #777 did NOT solve #758: it added canonical pinning, but manual
matches didn't write the pin.)
Fix: a manual ALBUM match on a canonical-recognised source now also pins
AND locks the canonical version to the chosen release:
- new canonical_locked column (same migration pattern as the other
canonical cols).
- set_album_canonical(..., locked=False) gains an atomic WHERE-clause
guard: an auto write can't overwrite a locked pin; a manual write
(locked=True) always wins. get_album_canonical exposes `locked`.
- library_manual_match pins canonical for album matches via the pure
should_pin_manual_canonical(entity_type, source).
The auto resolve job already skips already-pinned albums, so the lock is
protected on two fronts; the new guard also covers any future
re-resolution. A new manual match still overrides.
18 tests: the pure gate (+ a sync-invariant test vs _ALBUM_ID_COLUMNS)
and the DB lock seam (auto can't clobber a manual lock; manual overrides;
auto-over-auto still works). Additive — locked defaults False, so the
auto path is unchanged unless a manual lock exists. Full suite clean.
#798 follow-up. The enrichment worker's own loop already bridges to the
no-creds Spotify Free source during a rate-limit ban (its guard checks
is_spotify_metadata_available()). But the resume button's pre-check
(_spotify_resume_pre_check) blocked resume on ANY rate-limit with no
awareness of Free — so a Free-opted-in user who got rate-limited was
locked out of restarting the worker, unable to fall through to the free
API.
Fix: the resume guard now mirrors the worker. Block only when
rate-limited AND nothing can serve (plain auth, no Free) — where resuming
would just sleep out the ban. When Free is available it serves during the
ban (is_spotify_authenticated() is False while banned, so
is_spotify_metadata_available() reports the free source), so resume is
allowed and the worker bridges via Free, then returns to real auth once
the ban lifts. Stays real-API-first; Free is only the bridge.
The rule is pinned in a pure helper should_block_rate_limited_resume()
next to the other gate functions, with 3 tests. Full suite clean (only
pre-existing soundcloud /app env failures remain).
The post-scan reconcile previously ran AFTER the worker's 'finished'
signal, which flips db_update_state status to 'finished'. Automations
wait for a scan by polling that status, so they stopped waiting before
the reconcile ran — and the dashboard/Tools card showed "Completed" then
flipped to "Reading file tags…". For incremental scans this was
invisible (sub-second); for a full refresh it was a real gap (a chained
automation would fire minutes before the IDs were filled).
Fix: the worker now routes completion through _emit_finished(), which
runs self.post_scan_hook (the reconcile) FIRST, then emits 'finished'.
The hook is injected by the web layer (it owns path resolution). So:
- status stays 'running' through the reconcile,
- the reconcile pushes its phase ("Reading file tags for N new tracks…")
and per-track progress through the SAME db_update_state callbacks the
scan already uses — so automations, the dashboard card, and the Tools
page all see it for free and wait for it,
- 'finished' is emitted exactly once, AFTER the reconcile — race-free, no
status blip a poll could catch,
- best-effort: a hook exception never blocks 'finished', so a scan can't
get stranded as perpetually 'running'.
Both scan entry points (_run_database_update_task, _run_deep_scan_task)
set the hook before run()/run_deep_scan(); the redundant post-run calls
are removed.
5 ordering tests pin the contract (hook-before-finished, finished still
fires without a hook, hook exception doesn't block finished, hook gets
the worker). Full suite clean (only pre-existing soundcloud /app env
failures remain).
Extends the manual "Import IDs from File Tags" backfill so newly-scanned
files get their embedded provider IDs pulled into the DB automatically —
no button press needed to keep up with new music.
How it works:
- insert_or_update_media_track now returns 'inserted' / 'updated' / False
(truthy-compatible; existing `if track_success` callers unaffected) so
the scan worker can tell a genuinely new row from an update.
- DatabaseUpdateWorker collects the ids it newly INSERTED this run
(self._new_track_ids) across all insert paths (Plex/Jellyfin/deep).
- After run()/run_deep_scan(), web_server calls _reconcile_after_scan(),
which gap-fills embedded IDs for just those new tracks. Runs as a
post-scan pass (the scan loop itself is untouched/fast — the media
server API never exposes these custom IDs, so the file must be read
once regardless; batching at the end keeps it out of the hot loop and
best-effort so it can never abort a scan). A progress phase ("Reading
file tags for N new tracks…") surfaces the full-refresh tail.
Shared engine:
- New reconcile_library() in core does the paging + lazy parent-map
loading (only loads albums/artists actually referenced — cheap when
scoped to a few new tracks) + per-page commits. BOTH the manual button
and the scan hook call it, so there's one tested orchestration, no
duplication. The backfill job was refactored onto it.
Same hardened safety: gap-fill only, atomically guarded against
overwrite, schema-introspected, idempotent. Scoped to new arrivals for
incremental/deep; full refresh re-inserts everything as new (recovering
the IDs a full-refresh wipe destroys).
+10 reconcile tests (reconcile_library scope/idempotency/progress/stop +
the engine). Full suite clean (only pre-existing soundcloud /app env
failures remain).
Files SoulSync (or MusicBrainz Picard) already tagged carry Spotify /
iTunes / MusicBrainz / Deezer / Tidal / AudioDB / Genius / Last.fm IDs in
their metadata. Enrichment workers gate their queues on
{provider}_match_status IS NULL, so reading those IDs back and gap-filling
the {provider}_id + match_status='matched' columns lets the workers skip
the API lookup entirely — big API savings on an already-tagged library.
New manual job in Tools -> Database & Scanning ("Import IDs from File
Tags"): scans every library file, reads embedded IDs, fills any that are
missing in the DB. Background job + progress card, mirroring the
write-tags-batch pattern.
core/library/embedded_id_reconcile.py (pure + tested):
- plan_reconcile(): gap-fill plan for a track + its album + artist. Only
empty id columns are planned; a disagreeing embedded id is a conflict,
never applied.
- apply_reconcile_plan(): one guarded UPDATE per id column —
WHERE id=? AND (col IS NULL OR col=''). The guard makes the fill atomic:
if an enrichment worker matched the same entity between our read and
this write, the UPDATE affects 0 rows instead of clobbering it. Columns
are introspected so a schema missing a provider's columns is skipped.
- reconcile_track_row(): per-track orchestration (id extraction, plan ->
apply, keeping the in-memory parent maps fresh for sibling tracks).
Job hardening: paged track scan (bounded memory), per-page commits (don't
starve concurrent workers), per-file try/finally (one bad file can't abort
the run), counters from real rowcount.
Scope: 19 column-fills across 8 providers. MB *recording* (track) id is
left out (UFID frame the reader doesn't surface; Vorbis key ambiguous) —
MB album+artist are covered. Amazon/ASIN deliberately excluded (ASIN is a
different namespace than the worker's amazon_id). All target columns
verified against the live schema.
Purely additive: new module, two new endpoints, one new Tools card —
no existing behavior changed. 20 unit tests (incl. the concurrency guard).
Full suite clean (only pre-existing soundcloud /app env failures remain).
AcoustID returns a recording's title/artist in their ORIGINAL script
(e.g. "久石譲" for Joe Hisaishi) while SoulSync's expected metadata is
romanized/English. A correct download then fails verification on two
walls: the title can never clear the 0.70 similarity bar cross-script,
and the only skip path that ignores the title required a near-perfect
0.95 fingerprint plus a resolved alias. Result: every non-English
artist trips it. Two complementary fixes, per the reporter's two ideas.
Graceful fix (automatic):
- New pure core/matching/script_compat.py detects when two strings are
in genuinely different writing systems (CJK/Hangul/Cyrillic/Greek/
Arabic/Hebrew/Thai vs Latin). Accented Latin (Beyoncé, Sigur Rós)
stays Latin — no false trigger.
- acoustid_verification.py: when the EXPECTED artist and the matched
artist span scripts AND the artist is confirmed via the existing
MusicBrainz alias bridge, SKIP instead of quarantine, without the
0.95 floor (the 0.80 trust floor already gates the fingerprint).
- Deliberately narrow: keyed on the ARTIST spanning scripts + being
confirmed. A same-script artist with only a cross-script title keeps
the stricter 0.95 floor, so the #607 wrong-file protection (Kendrick
R.O.T.C, low-fingerprint Japanese-title) is untouched.
Per-request toggle (manual escape hatch):
- New "Skip AcoustID verification" checkbox in the download-missing
modal beside "Force Download All".
- skip_acoustid threads request -> batch -> per-track track_info ->
download context (same path as _playlist_folder_mode), landing on
the existing _skip_quarantine_check='acoustid' bypass. No new
mechanism; only the AcoustID gate is bypassed (integrity/bit-depth
still run).
Tests:
- tests/matching/test_script_compat.py — script-boundary cases.
- test_acoustid_skip_logic.py — Joe Hisaishi SKIPs at 0.85; unconfirmed
cross-script artist still FAILs; same-script low-fingerprint still
FAILs.
- test_downloads_candidates.py — toggle injects the bypass; absent
toggle keeps verification.
Full suite: 5169 passed; only pre-existing soundcloud /app env failures
remain. Zero regressions.
The Settings dropdown reverted 'Spotify Free' because _isMetadataSourceSelectable
reads _lastStatusPayload.spotify.free_installed, but that payload comes from the
WebSocket status:update push (_build_status_payload) — which sent the raw spotify
dict. The availability flags were only added to the GET /status endpoint, so the
frontend never saw free_installed and bounced the selection.
Extract _spotify_status_with_availability() (metadata_available + free_installed)
and use it in BOTH _build_status_payload (WebSocket) and get_status (HTTP poll),
so they can't drift. Now 'Spotify Free' is selectable when SpotipyFree is
installed.
Consistency fix: Spotify Free is now its own entry in the metadata-source
dropdown (alongside Spotify / iTunes / Deezer / MusicBrainz) instead of a
side-toggle. Stored as fallback_source='spotify' + spotify_free=true so all
downstream 'spotify' routing and the spotify_* columns are unchanged.
Refined gate model (no toggle):
- Connected user (has credentials) -> official; bridges to free AUTOMATICALLY
during a rate-limit ban (no opt-in needed).
- No-auth user -> must pick 'Spotify Free' in the dropdown; then free serves.
- Never opted into Spotify (no creds, didn't pick it) -> free never runs, so no
surprise scraping. _free_wanted() = has_credentials OR picked-spotify-free is
the guard.
- AUTHED + healthy -> official always; free never opens.
UI: dropdown gains 'Spotify Free (no credentials)' (selectable when the package
is installed — surfaced via status.free_installed, since selecting it is the
opt-in and can't depend on having selected it); load/save map the dropdown value
to the (fallback_source, spotify_free) pair; old checkbox removed.
Gate model pinned by 6 scenario tests (connected/healthy, connected/ratelimited
bridge, no-auth picked, no-auth not-opted-in, package-missing). 117 tests green.
Surfaces the opt-in Spotify Free source so it's usable end-to-end:
- Settings: 'Enable Spotify Free (no credentials)' toggle that saves
metadata.spotify_free (load + save wired). Clear best-effort/limitations note.
- config-status: adds spotify.metadata_available (configured OR free-available),
keeping the configured flag = has-credentials so the Connections indicator
stays honest. Search source picker shows Spotify when metadata_available.
- status payload: adds spotify.metadata_available; the Settings primary-source
selector now allows picking Spotify when authed OR free-available.
Verified gate composition: OFF by default (no surprise scraping); ON + no auth +
installed -> available & serving; AUTHED -> official always wins (free never
runs); missing package -> gracefully unavailable. JS + integrity + 111 tests green.
A manually-fixed mirrored track silently reverted to 'Wing It' after re-running
discovery. Two compounding causes:
- extra_data is MERGED on save (update_mirrored_track_extra_data), and the
manual-fix DB write (web_server.py) didn't clear the prior wing_it_fallback
flag — so a track fixed after being a Wing It stub kept wing_it_fallback=True.
- the Playlist Pipeline pre-scan checked wing_it_fallback BEFORE manual_match
(if/elif), so the stale flag won: the track was re-discovered and, on a miss,
fell back to Wing It — discarding the user's pick.
Fix: extracted the pre-scan gate into core.discovery.manual_match.should_rediscover
(manual_match checked FIRST = authoritative, regardless of leftover flags), and
the manual-fix write now also clears wing_it_fallback/unmatched_by_user. Behavior
is identical for every other branch — only the manual-vs-wing-it ordering changes.
Tested at the seam incl. the exact regression (wing_it_fallback + manual_match
both set -> skip). 227 discovery tests green.
After the duplicate-id ambiguity guard, an owned artist reached via a source
link (e.g. Kendrick's Deezer link) fell back to the bare source-only view
instead of the rich library view, because the URL path carries no name and the
duplicated id alone can't be matched.
get_artist_detail now resolves the source artist's name (reusing the #775
link-resolver's per-source artist fetch) when the id lookup is ambiguous and no
name was passed, then retries the library upgrade by name. So an owned artist
lands on the full library view; a genuinely-unowned one still renders
source-only (now with its name pre-resolved). Unique ids are unaffected.
Follow-up to the bare-ID footgun: a bare number like 525046 carries no
source and no entity type, so it resolved to whatever album happened to own
that id (a user pasting Kendrick's Deezer artist id got an unrelated album).
Now the resolver accepts provider URLs (and the explicit spotify: URI) only;
a bare/unrecognized string is rejected and the dropdown surfaces a hint to
paste a full link. URL parsing + album/track resolution are unchanged.
New 'Link / ID' input on the Search page: paste a Spotify / Apple Music /
MusicBrainz / Deezer URL (or a bare ID) and it's looked up directly on the
owning source — no fuzzy search, no scoring.
- core/search/by_id.py: source-agnostic parser (URL domain/path or bare-ID
format -> source,kind,id; numeric IDs fan out, first hit wins) + per-source
get-by-id dispatch + adapters projecting each provider's dict onto the
standard album/track card shape.
- /api/enhanced-search/by-id: thin additive route over resolve_identifier.
- Frontend: dedicated input that adopts the resolved source as active and
renders through the existing dropdown + download/import flow.
Purely additive — existing files are insertion-only; the resolver runs only
behind the new route. 29 seam tests cover parsing, shaping, fan-out, and
not-found.
The real path for discovery-modal syncs (Spotify-Public/Tidal/Deezer/Qobuz/
YouTube/iTunes-link/ListenBrainz/Beatport) is _start_source_sync ->
_submit_sync_task, which called _run_sync_task WITHOUT a sync_mode — so it used
the 'replace' default and never consulted the setting. (My earlier fix only
covered /api/sync/start, which these endpoints don't use — hence the log still
showing POST /api/spotify-public/sync/start ... mode: replace.)
_submit_sync_task now resolves the configured default via normalize_sync_mode
and passes it through, so all source syncs honor Settings > Playlist sync mode.
start_playlist_sync validated the resolved mode with 'if sync_mode not in
(replace, append): sync_mode = replace' — a pre-existing clamp two lines below
the config read I added, which silently downgraded a configured 'reconcile' to
'replace'. So config=reconcile resolved correctly then got clobbered, and every
sync ran replace regardless of the setting (and incognito didn't help — it's
backend, not cache).
Replace the hand-rolled clamp with a pure normalize_sync_mode(requested,
configured) helper (VALID_SYNC_MODES includes reconcile) so the resolution is
testable and can't silently drop a mode again. Regression tests cover
reconcile-from-config, request-overrides-config, and unknown->replace.
Replace mode (default) deletes + recreates the server playlist every sync,
which wipes its custom image, description, and identity. Add an opt-in
'reconcile' sync mode that edits the existing playlist in place — adds the
tracks now in the source, removes the ones gone — without destroying the
object, so the user's custom art/description survive.
- Pure planner plan_playlist_reconcile(current, desired) -> {add, remove}.
- Per-client reconcile_playlist: Plex addItems/removeItems on the same object;
Navidrome Subsonic updatePlaylist delta (songIdToAdd / descending
songIndexToRemove); Jellyfin add + remove-by-PlaylistItemId on /Playlists/{id}/Items.
- sync_service: reconcile branch with a replace FALLBACK (if a server's in-place
edit is unavailable/fails, sync still succeeds destructively — logged loudly).
- Default stays 'replace' (no behavior change). New Settings > Playlist sync mode
picker (replace/reconcile/append) backed by playlist_sync.mode; per-request
sync_mode still overrides.
- Reconcile skips the post-sync source-image push so a custom poster isn't
re-clobbered (the bug).
Tests: planner (add/remove/dedupe/order/empty) + reconcile-or-replace dispatch
(success / false-fallback / exception-fallback / no-method). Per-server in-place
API calls need dev validation against real Plex/Jellyfin/Navidrome.
NOTE: opt-in only; default behavior unchanged.
The mlm_save endpoint already fetches+validates the library track, so capture
its file_path and persist it on the manual match. This makes matches created
via the Manual Library Match tool re-resolvable after a rescan re-keys the
track (#787), matching the durability the Find & Add path now has.
Find & Add on the playlist-sync page only wrote sync_match_cache, which is
DELETEd wholesale after every DB scan — so the source->library pairing (and
the user's manual matches) reverted to 'extra'/red-dot on the next shallow
scan. The three match stores (sync_match_cache, manual_library_track_matches,
discovery extra_data) were disconnected and all pointed at tracks.id, which a
rescan re-keys (esp. Jellyfin/Navidrome GUIDs).
Unify the match so it's one durable fact, recorded once, honored everywhere:
- Find & Add also writes a durable manual_library_track_matches row (one-way;
the manual-match tool has no playlist to act on, so no reverse). Carries the
library file path.
- New library_file_path column (idempotent migration) + find_track_id_by_file_path:
re-resolve a stale library_track_id after a rescan re-keys the track, and
self-heal the row.
- The sync compare display's override lookup now falls back to the durable
manual match (resolve_durable_match_server_id) when sync_match_cache misses —
so the pairing persists across a scan instead of reverting to a red dot.
Purely additive: only adds matches when the cache returns nothing.
Tests: durable resolver (valid / stale-reresolve+self-heal / no-match / not-in-
playlist / missing-methods), file_path persistence + find_track_id_by_file_path.
The old per-download Retag Tool was limited (only native-pipeline downloads,
100-group cap, manual per-group) and did the wrong thing — it moved/reorganized
files instead of just tagging. It's superseded by the new Library Re-tag job
(whole-library, in-place) + the enhanced-library 'Write Tags' button.
Removed: the post-download record_retag_download ingestion hook (stops writing
retag_groups on every download), core/library/retag.py, the web_server state +
deps + /api/retag/* endpoints + the tool:retag WebSocket emit, the dashboard
card + both modals (index.html), the core.js socket handler, and the tools-page
wiring + help entry (wishlist-tools.js). Updated the import-pipeline test.
Verified: web_server parses, app + core imports OK, 392 tests pass, no live
references to removed symbols.
Left as inert (harmless) for a careful follow-up sweep: the retag_groups/
retag_tracks tables + their DB CRUD methods (no longer written/read), and the
now-orphaned retag JS helper functions (no entry point/wiring/socket calls them;
interspersed with wishlist functions, so not blind-deleted).
write_tags_to_file wrote the core fields + cover but never the source IDs
(Spotify/iTunes/MusicBrainz) the import post-process embeds. Added a focused
source.embed_known_source_ids() that writes ALREADY-KNOWN ids (from db_data)
via the canonical, Picard-compatible frame writer the import uses
(_write_embedded_metadata) — no API re-fetch, frames correct by construction.
write_tags_to_file now calls it whenever db_data carries id keys.
Fed from both paths: the enhanced-library 'Write Tags' button now carries the
track's spotify/itunes/musicbrainz ids, and the Library Re-tag job stamps the
matched album/track source ids onto each track. So both now write the full tag
set, not a subset.
- Bump _SOULSYNC_BASE_VERSION 2.6.5 -> 2.6.6 (the single source of truth that
propagates to the UI, backups, and the update check).
- Add the 2.6.6 What's New block (qBittorrent 5.2.0 login fix, Cover Art Filler
on-disk detection + file embedding + stricter matching, recommendations
explainability + Discover section, organize-by-playlist #780, nav/scroll perf
#783, dashboard mobile polish).
- Finalize the 2.6.5 block: it shipped in tag 2.6.5 but was left flagged
unreleased (so its notes never displayed) — stripped the flag + dated it per
the file's own release convention.
Adds get_recommendation_sources() — for each recommended similar artist it
resolves the polymorphic similar_artists.source_artist_id back to the display
names of the user's OWN artists (library + watchlist) that list it, by matching
against every provider-id column on both tables. The /api/discover/similar-artists
endpoint now attaches a 'because' array per recommendation so the UI can show
'because you have X, Y, Z' instead of just a count.
Seam tests cover: library + watchlist resolution across different provider-id
columns, dedup + name-sort, max_per cap, orphan source omission, profile scoping.
THE root cause of 'orb frozen, click does nothing visibly': when a socket is
connected, the orbs don't poll — update*Status() bails on socketConnected and
relies on server pushes. similar_artists was missing from BOTH the server emit
loop (_emit_enrichment_status_loop's workers dict) and the client dispatch
(core.js socket.on('enrichment:<id>')), so the orb never received status → never
updated. Clicks DID pause the backend (modal showed paused), but the orb visual
was frozen. Added the worker to the emit loop + the socket.on handler.
- get_stats now reports PERSISTENT counts from the DB (matched/not_found/pending
+ a progress.artists breakdown) instead of in-memory session counters, so the
dashboard orb tooltip and the Manage modal agree (was showing 0 vs 14 after a
restart) and it survives restarts — same approach as the other workers.
- Orb tooltip reads progress.artists ('Artists: 14 / 15 (93%)') like the rest.
- Worker now defaults to ON (running) instead of opt-in-paused; still honors a
saved pause across restarts. It self-paces (~3s/artist) and backs off on
MusicMap outages, so the orb spins/active like the others when there's work.
10 seam tests pass.
SoulSync standalone matches library tracks without Plex fetchItem,
reports missing counts correctly, and skips server playlist writes.
Automation re-syncs when the mirror grows; after sync finishes, starts
organize download (organize-by-playlist) or wishlist processing.
UI: Spotify URL playlist-folder controls, organize toggle layout in the
discovery modal, reload organize preference when reopening Download Missing.

Closes the gap where similar artists only existed for WATCHLIST artists: a new
background worker populates them for the whole LIBRARY, slotting into the
existing enrichment-worker pattern (bubble + Manage Enrichment Workers modal,
status/pause/resume, matched/not_found/pending/errors).
Per source-matched library artist → get_musicmap_similar_artists(name, 25)
(the same matcher the artist-detail page uses: fetches MusicMap names, matches
each to the user's source chain — primary + active fallbacks — returns only
matched artists) → store via add_or_update_similar_artist keyed by the artist's
metadata source id, the SAME key the watchlist scanner + artist map use, so the
two cooperate (idempotent upsert + retry_days window).
- core/similar_artists_worker.py: pure seams (pick_source_artist_id,
map_payload_to_store_kwargs, process_artist) + the threaded worker; skips
artists not yet source-matched; classifies not_found vs transient error
(retry after 30d).
- DB migration: similar_artists_match_status / _last_attempted on artists
(mirrors every other source worker's tracking columns).
- Registered in EnrichmentService + instantiated in web_server, DEFAULT-PAUSED
(opt-in) like Amazon — MusicMap is scraped/outage-prone + this is library-wide.
- SERVICE_ENTITY_SUPPORT['similar_artists']=('artist',) so the modal breakdown
('artists with / without similars') + Retry work; manual-match (inapplicable
to a relationship) is gated out via relationship:true.
- 10 seam tests; existing 80 enrichment tests still pass.
Note: keys under profile 1 (single-profile setups); multi-profile is future work.
The on-canvas overlay text can't be copied (and can't be grabbed mid-freeze), so
when perf mode is on ('d'), the frontend now also POSTs the render timings to
/api/discover/artist-map/perf ~1.5x/sec, which logs them as [ARTMAP-PERF] in
app.log. Lets the bottleneck be diagnosed from the server side with no manual
copying.
Persist organize_by_playlist on mirrored playlists and run playlist-folder
downloads from the auto-sync pipeline instead of the global wishlist phase.
Register SoulSync library rows after playlist-folder post-processing, route
failed organize batches to the wishlist correctly, and skip sync-time
unmatched wishlist only when organize download handles retries.
Invalidate stale playlist track caches on refresh (Spotify and Deezer ARL),
re-mirror on refetch, and improve standalone playlist modals (re-analysis,
Open in Mirrored). Add filesystem missing-track detection and tests.

The no-auth 'add by link' path scrapes Spotify's embed widget, which only ever
contains ~100 tracks and can't paginate — so big public playlists got
truncated. This adds an in-house anonymous fetch that pulls the FULL list:
- core/spotify_public_api.py: reads the anonymous web-player accessToken Spotify
already embeds in its own open.spotify.com page HTML (no app credentials, and
no rotating TOTP secret for us to maintain), then paginates
/v1/playlists/{id}/tracks 100 at a time until the whole playlist is pulled.
Returns the embed scraper's exact shape. Pure helpers + injected http_get so
it's unit-testable without the network.
- core/spotify_public_scraper.fetch_spotify_public(): tries the full fetch for
playlists; on ANY failure (or for albums) falls back to scrape_spotify_embed.
Worst case == today's behaviour, so the link path can't regress.
- web_server: the link-tab endpoint and the authed flow's last-resort scrape
now both go through fetch_spotify_public.
Scoped entirely to the spotify_public_* (no-auth) path — the authenticated
playlist sync is untouched. 11 tests (token extraction, normalisation,
pagination past 100, and the embed-fallback orchestration).
Caveat: rides Spotify's undocumented page-embedded token — expected to break
when they change their page; it degrades to the embed fallback, never crashes.
Needs a live click-through to confirm the token path works end to end (can't
hit Spotify from the test env).
Per-worker processing-order override + UI polish.
Feature — pin an entity group to enrich first:
- Each worker normally runs artist -> album -> track. A user can pin one
group (artist/album/track) to run first from the modal; the worker keeps
that group first until it's exhausted, then resumes the normal chain.
- core/worker_utils.py: read_enrichment_priority() (reads
<service>_enrichment_priority each loop, live) + priority_pending_item()
(shared, whitelisted query returning the worker's expected item shape;
Spotify/iTunes get album_individual/track_individual via a type map).
- A guarded ~6-line hook at the top of all 11 workers' _get_next_item.
CRITICAL: when nothing is pinned (default) the hook returns immediately,
so default enrichment order is byte-identical to before. Discogs (no track)
and Genius (no album) only honor their supported entities.
- core/enrichment/api.py: GET/POST /api/enrichment/<id>/priority (+ config_get
hook); POST validates the entity against what the source enriches.
- 14 new tests (helper shapes, exhaustion, route get/set/clear/validate).
UI:
- Refined hero header: identity + inline status left, single Pause right,
'now enriching' quiet sub-line; overall coverage % moved into the stats
section ('82% matched · 1,203 of 1,460'). Hero gently pulses while running.
- New processing-order strip: artist→album→track steps showing the live phase
(pulsing 'now'), pinned group ('first' + 📌), and done/remaining; click a
step to pin it, click again for auto.
py_compile clean across all 11 workers; 52 enrichment tests green.
Dashboard 'enrichment bubbles' could pause/hover but offered no way to
*manage* a worker. This adds a full management modal opened from a new
header button, covering all 11 enrichment sources.
Backend (testable core helper + seam tests; no live-DB dependency):
- core/enrichment/unmatched.py: pure, whitelisted SQL builders for the
unmatched browser. service/entity validated against a support map (never
interpolated raw); search + pagination bound as params; tracks join albums
for artwork; limit capped at 200.
- database/music_database.py: get_enrichment_unmatched() +
get_enrichment_breakdown() (the breakdown splits matched/not_found/pending,
which the existing get_stats().progress lumps together).
- core/enrichment/api.py: GET /api/enrichment/<id>/{unmatched,breakdown} on
the existing blueprint + a db_getter hook.
- web_server.py: wire db_getter=get_database.
- tests/enrichment/test_unmatched.py: 19 tests across builders, DB methods,
and Flask routes.
Frontend (vanilla, matches app conventions):
- webui/static/enrichment-manager.js: worker rail with live status + coverage
micro-bars, accent-themed detail panel (hero header, segmented matched/
not_found/pending stat cards, current item, pause/resume), and a searchable
paginated unmatched browser with inline manual match (reusing
search-service + manual-match) and retry (clear-match re-queues).
- Polish: entrance/exit motion, scroll-lock, Escape, refresh control,
flicker-free polling (in-place updates), skeleton loaders, relative
timestamps, per-worker accent theming, real dashboard logos reused at
runtime (with the same invert/circle treatment), responsive rail.
- index.html: header button + script include. style.css: full styling.
Reuses existing pause/resume, status, and manual search+assign endpoints.
Backend tests green (19 new + 11 existing enrichment tests).
The sync editor renders server covers as <img src="/api/navidrome/cover/{id}">,
but no Flask route ever served that path — so every Navidrome cover 404'd, on
every album, art or not. The source (left) side then went blank too: a source
row with no native art (e.g. YouTube, which provides none at mirror time) falls
back to borrowing the matched server track's cover — i.e. that same dead route.
So both sides collapsed to nothing.
Fix:
- New NavidromeClient.build_cover_art_url(cover_id) — builds the absolute,
Subsonic-authenticated getCoverArt URL (base_url + token/salt), keeping
credentials server-side. Uses a FIXED cover-art salt so the URL is
deterministic for a given (server, password, cover_id): a rotating salt (as
in _generate_auth_params) would make every request a unique URL → image-cache
miss every time + a dead, never-reused cache row per fetch. Token auth doesn't
require a unique salt, and the password is never exposed (only its salted md5).
- New route /api/navidrome/cover/<cover_id> — resolves that URL and streams the
image through the shared image cache (same pattern as /api/image-proxy), with
a private max-age so the browser caches by the stable route URL.
Effect: server side works for any album that has art in Navidrome; matched
source rows with no native art now borrow the (now-working) server cover.
Unmatched YouTube rows stay blank — no image exists anywhere to show.
Tests: tests/test_navidrome_cover_url.py (8) — URL structure + salted-token auth
(never the raw password), determinism (same id -> same URL so the cache hits;
different id/password -> different URL), optional size, and the not-connected /
no-id / no-credentials guards.
Caveats: not executed against a live Navidrome (no server in CI) — the URL
builder is unit-tested; the route's cache→HTTP→bytes round-trip is read-verified
only. Scope is the sync editor's Navidrome route; Plex/Jellyfin server-cover
branches and any other modals using a different mechanism are untouched.
Three compounding bugs hit tracks whose source metadata is YouTube/streaming-
shaped — title "Artist - Song", artist "Official Artist"/"Artist - Topic"/
"ArtistVEVO" (reported: "Arctic Monkeys - Do I Wanna Know?" by "Official Arctic
Monkeys"). Server-agnostic — affects Plex/Jellyfin/Navidrome, not just the
reporter's Navidrome.
Bug A — the match fails. The confidence scorer and the editor's reconcile both
compared the raw "Artist - Song" title against the library's clean "Song"; the
length-ratio penalty + floor drove it to ~0.18 (NO-MATCH), so the track showed
unmatched while its server copy showed as an orphan "extra". New pure
core/text/source_title.py (clean_source_artist / strip_artist_prefix /
canonical_source_track) strips the channel/video decoration, applied at BOTH
matching seams: services/sync_service._find_track_in_media_server (tries raw
then canonical, keeps the best) and the editor reconcile. Conservative: a title
prefix is stripped only when it equals the artist, so "Self-Titled", "Jay-Z",
and "Marvin Gaye" (by another artist) are untouched, and the canonical form is
an additional best-of candidate so it can only help.
Bug B — manual matches never persisted. get_server_playlist_tracks built the
per-source entry WITHOUT source_track_id, so "Find & add" posted an empty id
and _persist_find_and_add_match returned early. The match reverted to "extra"
on reload and re-adding looped. The editor's 3-pass matcher is now lifted to a
pure, tested core.sync.playlist_reconcile.reconcile_playlist that includes
source_track_id (the frontend at pages-extra.js:1836 already reads + sends it).
Bug C — manual match duplicated + delete wiped all copies. "Find & add" always
inserted, so linking a source to an already-present server track appended a
duplicate (pos 72, 73...); remove filtered out EVERY entry with the target id.
New pure core.sync.playlist_edit (plan_playlist_add: link-don't-duplicate when
the target is already present; remove_one_occurrence: drop a single copy) wired
into the Plex/Jellyfin/Navidrome add + remove branches.
Tests (extreme): tests/test_source_title.py (35), tests/test_playlist_reconcile.py
(11 — incl. the reported case, parity for override/exact/fuzzy/extra, and
duplicate-server handling), tests/test_playlist_edit.py (12). 286 matching/sync
tests still pass.
Caveats: the sync_service change and the add/remove/editor endpoints are
read-verified, not executed against a live media server (none in CI). The pure
cores they call are exhaustively unit-tested; output-shape parity of the
reconcile lift is covered. Delete removes the first matching copy (duplicates
are identical, so harmless).
After an update, installs became unusable: the Amazon enrichment worker runs by
default, the default public T2Tunes proxy (t2tunes.site) was returning
503 'Amazon Music API is not initialized', and the worker treated every album
as an individual error -- logging an ERROR per item, churning network + DB
continuously across the whole library, and marking every row 'error' (a state
the retry tiers never re-attempt, so even after the proxy recovered nothing
re-enriched). The reporter couldn't reach the UI to turn it off.
Two-part fix:
1. Source-outage circuit breaker (core/amazon_outage.py, pure + tested):
- is_source_outage(exc) distinguishes a whole-source outage (HTTP 5xx,
'not initialized', connection failure, non-JSON error page) from a real
per-item miss (404, transient 400, etc.).
- On an outage the worker now leaves the item UNTOUCHED (so it's retried once
the proxy recovers instead of being permanently burned to 'error'), logs
ONCE per streak, and backs off with next_poll_delay_seconds() -- escalating
30s -> 60s -> ... capped at 30 min -- instead of grinding every 2s. It
auto-resumes the normal cadence the moment the source answers (success OR a
non-outage error both clear the streak).
- AmazonClientError now carries status_code so detection doesn't rely on
message parsing.
2. Opt-in by default (web_server.py): amazon_enrichment_paused now defaults to
True. Because enrichment depends on an external public proxy that can be
down, it stays paused unless the user explicitly enables it -- a proxy outage
can no longer take down installs that never opted in. (Behaviour change:
anyone on the old auto-on default is now paused; re-enable in Settings.)
Together: on update the worker is paused -> no flood -> UI accessible; opted-in
users are protected from future outages by the breaker.
Tests: tests/test_amazon_outage.py (12) pin the classifier across every error
surface (incl. the exact 503 'not initialized' case) and the back-off schedule
(monotonic, capped). 157 Amazon tests pass; lint clean.
Note: could not reproduce the exact 'UI fully unreachable' mechanism remotely
(WAL + 8 gthreads shouldn't hard-lock); the fix removes the flood/churn that is
the practical cause and defaults the feature off.
Lets users pick which providers' cover art to use and in what priority,
generalizing the single prefer_caa_art toggle into an ordered, mix-and-match
list (Sokhi's request). Fully opt-in: default album_art_order is [], so every
existing install is byte-for-byte unchanged until the user enables sources.
How it works:
- Per album, walk the user's ordered sources top-to-bottom; the first source
that actually has THIS album's cover wins. A miss falls through to the next;
if all miss, the download's own art is kept (today's default). The worst case
is always exactly the cover you'd get today -- never wrong art, never an
error into the download.
- Connection-gated: a source is only tried when the user is connected to it
(free sources CAA/Deezer/iTunes/AudioDB always; Spotify only when
authenticated). Tidal/Qobuz/HiFi deferred (cover-URL construction + no clean
core accessor -- not shipping unverified extraction).
- Album-match validated: a source's art is used only when the album it returns
matches the requested artist+album (significant-token subset, tolerant of
Deluxe/Remastered/articles/feat./multi-artist). A loose top search hit for a
different record is treated as a miss -> guarantees no wrong-album art.
- The list supersedes the legacy prefer_caa_art toggle: when album_art_order is
non-empty it is the sole authority (add 'caa' to the list to use Cover Art
Archive), and prefer_caa_art is neutralized for both the embedded-tag art and
cover.jpg paths. With an empty list, prefer_caa_art behaves exactly as before.
Implementation:
- core/metadata/art_sources.py: pure resolver -- effective_art_order (config +
legacy back-compat) and resolve_cover_art (ordered walk + fallback,
exception-safe per source). No network/config/DB; fully unit-testable.
- core/metadata/art_lookup.py: availability gating, per-source lookups against
existing clients (Deezer/iTunes/AudioDB/Spotify search + CAA via MBID),
album-match validation, per-album caching, and select_preferred_art_url --
the single gate the pipeline calls (no-op unless an explicit list is set).
- core/metadata/artwork.py: wired into embed_album_art_metadata and
download_cover_art, gated so no configured list == current behavior.
- web_server.py: GET /api/metadata/art-sources (connected sources only).
- config/settings.py: default album_art_order: [].
- webui (index.html + settings.js): reorderable list in Core Features reusing
the hybrid-source-list pattern + real service logos (with emoji fallback);
load/save wired through the existing metadata_enhancement settings flow.
loadArtSourceOrder populates the saved order synchronously (filtered to known
sources, not availability) so a save before the availability fetch resolves,
or a temporarily-disconnected source, can never wipe the saved order.
Tests: 40 unit/seam tests (resolver ordering/fallback/back-compat, availability,
per-source extraction, album-match validation incl. wrong-album/wrong-artist
rejection, caching, exception-safety, the off-by-default gate). Full metadata
suite still green (610 passed) -- the gated integration changes nothing when no
list is configured.
Note: the settings UI (DOM-heavy, not unit-testable in the JS harness) and the
live per-source art-fetch quality are validated by manual testing.
New GET /api/downloads/task/<id>/detail merges the live download task with its
library_history row (the data the Download History cards show) into one payload
the upcoming track-detail modal renders: status kind, title/artist/album,
source, quality, final location, AcoustID verdict, and expected-vs-downloaded.
Assembly + status classification live in core/downloads/track_detail.py as a
pure, importable build_track_detail()/classify_status_kind() (9 unit tests);
the endpoint is thin glue that looks up the matching history row by track.
Accepting a quarantined item re-imported the file correctly, but the download
modal kept showing 'Quarantined'. The re-import ran through the inner pipeline,
which doesn't mark task completion (that's the verification wrapper's job), and
the sidecar context had no task_id anyway (popped before quarantine).
The chooser's Accept now sends the originating task_id, and the endpoint
re-runs the import through the verification wrapper with that task_id (+ batch_id
looked up from the task), so the task is marked completed only after the file is
verified moved — the row flips to Completed on the next poll. Manager-tab
approvals (no task_id, no JSON body — handled via get_json(silent=True)) keep
the original inner-pipeline path.
Also clear has-candidates + the quarantine dataset on every status render so a
row that goes quarantined -> completed doesn't keep a stale chooser attached.
Clicking a quarantined track's status used to open the generic search modal,
identical to a plain failure — no way to review or recover the file. It now
opens a chooser:
- Listen: streams the file in-app via a new /api/quarantine/<id>/stream
endpoint (range-supported; the real audio Content-Type is recovered from the
sidecar since the on-disk file ends in .quarantined).
- Accept & Import: existing /approve (restore + re-import, gates bypassed).
- Search for a different result: the existing candidates modal (old behavior).
Non-quarantine failures (not_found / failed / cancelled) are unchanged — a
single click listener routes by dataset set at render time, so a task that
fails then later quarantines can't end up double-bound.
Also fixes the Accept failure on Windows: the Listen stream holds an open file
handle, so the subsequent restore move hit WinError 32 ('file in use') and the
endpoint mislabeled it 'thin sidecar'. Accept now releases the audio handle
before approving, and approve/recover moves retry briefly on transient OS locks
(_move_with_retry). Accept also auto-falls-back to Recover-to-Staging for
genuinely thin/orphaned sidecars.
Tests: stream-info resolution (sidecar + filename-fallback + missing), and
_move_with_retry success/give-up.
The save endpoint coerced library_track_id with int(), which rejected
every non-numeric id with "Invalid library track id". Library ids are
str(ratingKey) — numeric for Plex but GUIDs/hashes for Navidrome,
Jellyfin, and other Subsonic servers — and are stored in the TEXT
tracks.id column, so the coercion broke manual matching on every
non-Plex server.
Replace the int() coercion with a normalize_library_track_id() helper
that trims and rejects only empty input, passing the opaque string id
straight through. Plex numeric ids are unaffected (SQLite INTEGER
affinity still stores a clean numeric string as an int, so existing
matches are byte-identical) and no schema migration is needed (the
INTEGER column already stores non-numeric ids as text).
Tests: pure-helper cases (numeric/GUID/whitespace/empty) plus a real-DB
round-trip proving a GUID id saves, reads back unchanged, and enriches.
Post-incident hardening. A WAL-mode DB corrupted (most likely an interrupted
write during a hard restart), and the backup routine made it unrecoverable:
it (a) never checked integrity, so src.backup() faithfully copied the corrupt
pages into every rolling backup, and (b) pruned oldest-by-mtime, so each new
corrupt backup evicted the last good one. Result: all snapshots poisoned.
New core/db_integrity.py (pure, unit-tested):
- quick_check()/is_healthy(): fast read-only PRAGMA quick_check probe.
- safe_backup(): verifies the SOURCE is healthy BEFORE the Online-Backup copy
and the RESULT after; refuses + discards rather than save a corrupt copy.
- prune_backups(): rotation that NEVER deletes the most-recent verified-healthy
backup, even to honor max_keep — so a run of bad backups can't drop your last
good snapshot.
Wired into BOTH backup paths (the /api/database/backup endpoint and the
auto_backup_database automation handler) — they now refuse on integrity failure
(409 / error status, existing backups untouched) and prune safely.
Tests: tests/test_db_integrity.py (8) using REAL temp DBs incl. a physically
corrupted one — proves refuse-corrupt-source, discard-corrupt-result, and the
exact incident scenario (newest backups corrupt -> the older healthy one is
protected from pruning). Existing maintenance-handler backup test still green
(29 passed). compile + ruff clean.
NOTE: this prevents silent backup poisoning; it does NOT stop the underlying
corruption. Follow-ups still worth doing: WAL-checkpoint on clean shutdown +
a periodic live-DB integrity alert (so corruption is caught on day 1).
listening_history was populated ONLY from the media server; the web player
recorded nothing. Now a play heard ~10s logs to listening_history AND bumps
tracks.play_count/last_played — so the existing 'recently played' query reflects
actual SoulSync listening, and the Phase-2 smart-radio recency signal gets real
data.
- core/playback/play_log.build_play_event(): pure, DB-agnostic normalizer from
player payload -> listening_history event shape. Caller supplies the
timestamp (stays pure). Composite/streamed ids never become the int
db_track_id; bool ids rejected; missing title -> skip. 9 unit tests.
- MusicDatabase.record_web_player_play(): inserts the history row + increments
play_count/last_played for the library track in one call.
- /api/library/log-play: thin endpoint, server-side timestamp, best-effort
(logging failure never 500s / never affects playback).
- Frontend: npMaybeLogPlay on timeupdate fires once per track at the 10s
threshold (flag reset in setTrackInfo, set-before-fetch so it can't
double-fire), fully fire-and-forget.
Pure builder is unit-tested; the DB write can't run in-sandbox (real DB throws)
so it's a thin straightforward insert+update. JS + web_server parse clean.
Self-audit of the revamp surface found real bugs, now fixed:
- DOUBLE-ADVANCE race: crossfade starts ~6s before track end, but when the
track actually 'ended' fired, onAudioEnded ALSO advanced — two skips.
onAudioEnded now bails when npXfadeActive (crossfade owns the advance).
- STRAY CROSSFADE on manual skip/stop: skipping or stopping mid-fade left the
interval running, firing npFinishCrossfade on top of the manual change, and
left the second <audio> playing. Added npCancelCrossfade() (clears the timer,
tears down the 2nd audio, restores main volume) called at the top of
playQueueItem and in handleStop. The fade interval also self-checks
npXfadeActive each tick. npFinishCrossfade clears all flags cleanly so the
legitimate handoff isn't treated as an abort.
- stream_start: moved 'global stream_background_task' to function top (it was
declared inside an if-block — parsed, but brittle/bad form).
web_server parses; 76 streaming+radio tests pass; JS syntax clean; CSS balance
unchanged from HEAD.
Wires the StreamStateStore (Phase 3a) into the live routes so each browser/
device gets its OWN playback instead of every client sharing one global
stream_state. Fixes the long-standing limit where a second tab/device/listener
would hijack the one playback.
- _stream_session_id(): stable per-browser id stored in the Flask session
cookie (falls back to DEFAULT when no request context — e.g. the socket
broadcast thread — so single-user behavior is identical).
- _current_stream_state(): the StreamSession for the calling browser.
- Routes rewired to the caller's session + its own lock: /api/library/play,
/api/stream/start, /api/stream/status, /stream/audio, /api/stream/stop.
- Background tasks tracked per session (stream_tasks[sid]) instead of one
global Future, so stopping/replacing one listener's stream doesn't cancel
another's. Executor bumped 1 -> 4 workers so concurrent listeners don't
queue behind each other.
- Per-session staging: named sessions stage under Stream/<sid>/Stream so
listeners never clear each other's files; default session keeps flat Stream/.
- /stream/status now returns THIS listener's state, which is what the frontend
polls — so per-listener works without touching the socket broadcast (left
serving the default session, now vestigial for status).
Isolation invariant covered by tests/streaming/test_stream_state_store.py
(distinct sessions independent, default stable). The route-level cookie wiring
+ actual two-client no-collision behavior need live multi-client verification
(can't be tested without booting Flask + separate cookies) — EXPERIMENTAL,
needs Boulder to test with 2 browsers/devices. 33 streaming tests still pass;
web_server parses.
Crossfade was a no-op toggle. Real crossfade needs two tracks audible at once,
but /stream/audio only serves the ONE current track (single global
stream_state). So:
- web_server: extracted the range-serving body of /stream/audio into
_serve_audio_file_with_range, and added /stream/library-audio?path= which
serves an arbitrary LIBRARY file through it. Security: the path is resolved
via _resolve_library_file_path (same validator /api/library/play uses) so it
only serves files inside the configured transfer/download/media-library
dirs — not arbitrary disk.
- frontend: a second hidden <audio> (#audio-player-xfade) preloads the NEXT
library track when the current one is within 6s of ending (crossfade on,
not repeat-one), ramps the two volumes in opposite directions, then hands
off to playQueueItem so all normal now-playing state is set.
Honest limits (documented in code): library→library only (streamed tracks
hard-cut as before); there's a brief silent reload at hand-off because
playQueueItem re-points the single stream_state — the perceived crossfade has
already happened by then. EXPERIMENTAL — needs Boulder's live audio
verification; I can't test audio in-sandbox.
33 streaming tests still pass (stream_audio refactor is behavior-preserving).
Foundation for multi-listener playback. Today web_server.py keeps ONE global
stream_state dict + one lock (web_server.py:747), so the whole server shares a
single 'currently playing' — every tab/device is a remote for the same
playback and two listeners collide. That global is woven through ~22 sites and
isn't unit-testable where it lives.
Lifted into core/streaming/state.py WITHOUT changing behavior:
- StreamSession: one playback's state, dict-compatible (s['k'], s.get,
s.update, 'k' in s) so existing call sites work unchanged, each with its
OWN RLock so distinct sessions never block/clobber each other.
- StreamStateStore: registry of named sessions; lazy + race-safe create;
DEFAULT session reproduces today's exact single-global behavior. Also
drop()/active_ids()/session_ids() for the eventual per-listener wiring.
web_server.py now binds (DEFAULT) and
. Drop-in: every .update()/[k]/.get()/ site behaves identically. _set_stream_state routes a reassign
through session.replace() so the store's session stays the live object (it's
effectively dead — prepare.py only mutates in place — but safe now).
Honest scope: this is the PROVABLE half of Phase 3. The remaining half (3b:
derive a per-browser session id, per-session Stream/ staging, executor
concurrency, disconnect cleanup) is browser-coupled and can't be verified
without driving 2+ live clients — deferred to a live session. The store API is
already shaped for it.
Tests (tests/streaming/, 33 total):
- test_stream_state_store.py (19): session dict-compat, isolation, lazy
create, drop rules, active_ids, concurrent-create race safety.
- test_stream_state_callsite_compat.py (7): every real web_server access
pattern (library/play, stream/start, status, audio guard, stop, prepare
in-place mutation, set->replace) against the exact object web_server binds.
- test_prepare.py +1: real prepare worker drives an actual StreamSession.
76 streaming+radio tests green; ruff clean; web_server.py parses.
