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.
7-step full-screen wizard: Welcome, Metadata Source, Download Source,
Paths & Media Server, Add Artists, First Download, Done. All settings
save to DB identically to the Settings page. Supports all 6 download
sources with inline config and test buttons. First download goes through
the full matched download pipeline with metadata context.
Fixes:
- Download clients (YouTube/HiFi/Tidal/Qobuz/Deezer) now reload
download_path when settings change instead of caching from init
- watchlist_artists table migrations now include deezer_artist_id and
discogs_artist_id in all 3 table rebuild locations (was being dropped)
- CREATE TABLE for watchlist_artists includes all provider ID columns
- Serverless download sources (YouTube/HiFi/Qobuz) show green status
instead of red disconnected on sidebar and dashboard
- Suppress repeated slskd 401 errors — logs once then silences until
connection recovers
Stripped 4,200+ emoji characters from print(), logger calls across
39 Python files. Logs are now clean text — easier to grep, more
professional, no encoding issues on terminals without Unicode support.
Seasonal config icons preserved for UI display.
Click any video card in Music Videos tab to download. Flow:
1. Search primary metadata source for clean artist/title
2. Fall back to YouTube title parsing if no match
3. Download video via yt-dlp (best quality MP4)
4. Save to configured Music Videos folder as Artist/Title-video.mp4
UI shows circular progress ring on the thumbnail during download,
green checkmark on completion, red X on error (clickable to retry).
Cards are non-interactive while downloading.
Backend: /api/music-video/download and /api/music-video/status endpoints
YouTube client: download_music_video() method keeps video format
New "Music Videos" pill tab alongside Spotify/Deezer/iTunes/Discogs
in both enhanced search and global search. Searches YouTube via yt-dlp
and displays results in a video card grid with 16:9 thumbnails, play
overlay, duration badge, channel name, and view count.
- Backend: /api/enhanced-search/source/youtube_videos endpoint with
search_videos() method on YouTubeClient returning YouTubeSearchResult
- Frontend: Video grid layout with responsive cards, YouTube red tab
color, proper section hiding when switching between metadata and
video tabs
- Global search: Full parity with enhanced search video rendering
- No download functionality yet — display only
YouTube's auto-generated artist channels use the format "Artist - Topic"
as the channel name. This suffix was not being stripped during playlist
parsing, causing metadata discovery to fail (e.g., searching for
"Koven - Topic" instead of "Koven" on iTunes/Deezer).
Fixed in all three places where YouTube artist names are cleaned:
- web_server.py clean_youtube_artist() — playlist parsing
- ui/pages/sync.py clean_youtube_artist() — UI-side parsing
- core/youtube_client.py — search result fallback artist extraction
Root cause: two issues compounding.
1. extractor_args with player_client: ['android', 'web'] + skip: ['hls', 'dash']
stripped all real audio formats. Android client returns HLS/DASH streams,
skip removes them, leaving only storyboard thumbnails. bestaudio then fails
because there's nothing valid to select.
2. Browser cookies (cookiesfrombrowser) cause authenticated YouTube sessions
to return restricted format data for some videos. Same video works fine
without cookies.
Fix:
- Removed all hardcoded player_client and skip overrides from 4 locations
(download opts, connection check, search, retry). Let yt-dlp use its own
defaults which are updated with each release.
- Retry strategy: attempt 1 uses cookies (respects user setting), attempt 2
drops cookies (fixes auth-restricted formats), attempt 3 uses format 'best'
as last resort.
- Updated user_agent to Chrome 131.
Implemented clear_all_completed_downloads in YouTubeClient to remove completed, cancelled, errored, and aborted downloads from memory. Updated DownloadOrchestrator to call this method, ensuring both Soulseek and YouTube completed downloads are cleared.
Adjusts matching weights for YouTube sources to rely more on title and duration, adds a shutdown callback to the YouTube client to prevent new downloads during shutdown, and enhances post-processing to reliably resolve actual YouTube file paths. Improves error handling for file removal, ensures no new batch downloads start during shutdown, and refines download monitoring to trigger post-processing on completed YouTube downloads. Also increases YouTube download retries and improves logging for debugging.
Introduces a DownloadOrchestrator class to route downloads between Soulseek and YouTube based on user-configurable modes (Soulseek only, YouTube only, Hybrid with fallback). Updates web server and UI to support new download source settings, including hybrid mode options and YouTube confidence threshold. Refactors YouTube client for thread-safe download management and bot detection bypass. Ensures quality filtering is skipped for YouTube results and improves file matching and post-processing logic for YouTube downloads.
