Five issues kettui flagged on PR #377: - Worker race (reorganize_queue.py): _next_queued() picked an item and released the lock, then re-acquired to flip status='running'. A cancel() landing in that window marked the item cancelled but the worker still ran it. Replaced with _claim_next_or_wait() that picks AND flips under one lock acquisition. - Wakeup race (reorganize_queue.py): _wakeup.clear() after the empty check could lose an enqueue's _wakeup.set(), parking a freshly-queued album for up to 60 seconds. Replaced Lock + Event with a single threading.Condition; cond.wait() releases and re-acquires atomically on notify. - Bulk dedupe (reorganize_queue.py:enqueue_many): looped single-item enqueue, so a duplicate album_id later in the same batch could slip through if the worker finished the first copy before the loop reached the second. Now holds the lock for the whole batch and tracks a per-batch seen set, so intra-batch duplicates dedupe against each other and not just pre-existing items. - Preview button stuck disabled (library.js:loadReorganizePreview): early returns and thrown errors skipped the re-enable line. Moved state into a canApply flag committed in finally, so any exit path lands the button correctly. - DB helpers swallowing failures (music_database.py): get_album_display_meta and get_artist_albums_for_reorganize used to catch every Exception and return None / [], so a real DB outage masqueraded as "album not found" / "no albums". Now lets exceptions bubble; the route layer already wraps them as 500. Tests: - test_cancel_and_run_are_mutually_exclusive — hammers enqueue+cancel pairs and asserts the invariant that no successfully-cancelled item ever ran (catches regressions to the atomic pick). - test_enqueue_many_dedupes_batch_internal_duplicates — pins the intra-batch dedupe. - test_get_album_display_meta_propagates_db_errors and test_get_artist_albums_for_reorganize_propagates_db_errors — pin the bubble-up behavior. Changelog updated in helper.js and version modal. |
