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.
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.
Track per-quality-tier failure reasons across all failure paths (stream
error, empty manifest, download exception, stub file, MP4 extraction
failure) and include them in the exhausted-tiers log message so failures
are diagnosable from logs.
When HiRes is configured with no fallback and all tiers are exhausted,
log an actionable hint directing the user to enable Quality Fallback.
Surface Tidal-specific error messages in the UI task on retry
exhaustion: distinguishes HiRes-unavailable (with actionable guidance)
from general Tidal auth/quality failures, rather than showing the
generic Soulseek error string.
Each streaming source (Tidal, Qobuz, HiFi, Deezer) now has an "Allow
quality fallback" checkbox in Settings. When disabled, the source only
tries the exact quality selected — if unavailable, it skips and lets
the orchestrator try the next source. Default is ON (current behavior).
Adds Tidal as a third download source alongside Soulseek and YouTube. Uses the tidalapi library with device-flow authentication to search and download tracks in configurable quality (Low/High/Lossless/HiRes) with automatic fallback. Integrates into the download orchestrator for all modes (Tidal Only, Hybrid with fallback chain), the transfer monitor, post-processing pipeline, and file finder. Frontend includes download settings with quality selector, device auth flow, and dynamic sidebar/dashboard labels that reflect the active download source. No breaking changes for existing users.
