SQLite Error 5: 'database is locked
See original GitHub issueEDIT 11/11/2020: This issue should now be fixed on newly created BaGet databases. Older installations can circumvent this issue by enabling write-ahead logging on your SQLite database. You can check if your SQLite database has write-ahead logging enabled by running the query PRAGMA journal_mode
and getting the result wal
. If necessary, you can enable write-ahead logging by running PRAGMA journal_mode=WAL;
.
Original bug report...
I’m trying BaGet with SqlLite backend and I’m seeing these error messages in the log, not sure if this is expected. Maybe this can be improved?

@loic-sharma I have just run about 20-30 simultaneous restores and the error reappeared.
My database is using the WAL journaling mode:
An example stack trace:
It seems that enabling Write-Ahead Logging may resolve this issue. See:
https://github.com/aspnet/EntityFrameworkCore/issues/14059 https://stackoverflow.com/questions/48651548/sqlite-terribly-slow-vs-postgres-with-asp-net-core
I’ll try to reproduce this issue and I’ll see if enabling write-ahead logging helps.
