Roland f61cbb6e81 videos: channel POST begins as a writer ... POST /api/videos/channels failed with "database is locked" on `INSERT INTO collection` on the docker WROLPi while background workers (config saves, refreshes) were writing. The handler wrote through the deferred request session: `create_channel` reads (the URL/name/directory conflict check) and then INSERTs, and SQLite refuses that mid-transaction lock upgrade instantly when another connection wrote in between -- busy_timeout is skipped for upgrades. Same shape and same fix as POST /api/download (daf2ba39): the handler now uses `get_db_session(commit=True)`, which begins IMMEDIATE so the concurrent writer waits its turn, and which commits before the refresh is fired so the refresh does not wait on a lock the request still holds. The regression test commits a write from a second connection between the handler's conflict check and its INSERT. The existing `write_lock_held_briefly` helper cannot reproduce this: the Sanic test client takes over a second to start the app, so its lock is released before the handler runs. Before the fix the test fails with the production error verbatim. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>		2026-09-15 14:03:27 -06:00
