(1) when the user picked a candidate and that download failed (e.g. soundcloud 404 on a stale track url), the auto-retry monitor would treat it like any other failed auto-attempt — yank the task back to "searching" and pick a different candidate. felt completely wrong from the user\'s perspective: "i picked THIS one, why is it searching for something else?" now manual picks are tagged with a `_user_manual_pick` flag and the auto-retry path bails on it. failure surfaces to the user instead of getting silently fallen-back. (2) non-soulseek manual picks (youtube / tidal / qobuz / hifi / deezer / soundcloud / lidarr) were getting stuck at "downloading 0%" forever even after their engine reported terminal failure. cause: status polling went into a "let monitor handle retry" branch that never fired because manual picks bail on retry — task was orphaned in downloading state. fix: when the engine reports Errored on a manual pick, mark the task failed directly, don\'t defer to the monitor. plus an engine-state fallback path covers the rare race where the orchestrator\'s pre-populated transfer lookup is missing the entry. (3) failed / not_found rows were only clickable when the auto-search had cached candidates — but the whole point of opening the modal now is to RUN a manual search, which doesn\'t need pre-existing candidates. now every failed / not_found / cancelled row opens the modal regardless. (4) one nasty deadlock fix in the process: the new "mark failed" path was synchronously calling `on_download_completed` while holding `tasks_lock`, which itself re-acquires the same lock — `threading.Lock` is non-reentrant so the polling thread wedged forever. while wedged the lock was held → every other endpoint that needed it (including /candidates → can\'t open OTHER modals) hung waiting. moved completion callbacks onto a daemon thread so the lock releases first. (5) manual download worker now runs on its own dedicated thread instead of competing with the batch\'s 3-worker `missing_download_executor` pool — saturated batches no longer queue manual picks indefinitely. all changes are scoped to manual picks only via the `_user_manual_pick` flag — auto-attempt flow is byte-identical to before. 17 unit tests pin the gate behavior (status engine fallback / monitor retry skip / IF-branch failure transition / auto-attempt skip).', page: 'downloads' }, { title: 'Manual Import: Stop Writing "Unknown Artist / album_id / 0 tracks" Garbage', desc: 'github issue #524 (radoslav-orlov): clicking an album in the import page → all imported albums landed in the library as "Unknown Artist" with the raw 10-digit album id as the title and 0 tracks. cause: the click handler `importPageSelectAlbum(albumId)` was passing only the id to the `/api/import/album/match` POST. the search response carried `source` (which metadata source the album_id came from) + `album_name` + `album_artist`, but the click discarded everything except the id. backend `get_artist_album_tracks` then guessed the source via the configured primary-source priority chain — for a non-deezer-primary user clicking a deezer search result, the chain tries spotify/itunes/discogs first against a deezer numeric id, all return None, and the lookup falls through to the failure-fallback dict (`name = album_id`, no artist field, `total_tracks = 0`). that broken metadata then flowed through the import pipeline → soulsync standalone library got the garbage rows. fix: cache album lookup by id when the suggestions / search renderers run, then have `importPageSelectAlbum` pull `source` + `name` + `artist` from the cache and include them in the match POST. backend now also logs a clear warning when source is missing from the match request, so any future caller dropping it shows up in app.log instead of silently corrupting library imports.', page: 'import' }, diff --git a/webui/static/stats-automations.js b/webui/static/stats-automations.js index 4976f471..48abb356 100644 --- a/webui/static/stats-automations.js +++ b/webui/static/stats-automations.js @@ -759,26 +759,37 @@ async function _autoImportLoadStatus() { if (settingsRow) settingsRow.style.display = data.running ?
