The SQLCipher engine used a dummy sqlite:// URL with a creator function, which caused SQLAlchemy to auto-select SingletonThreadPool. This pool non-deterministically closes in-use connections when thread count exceeds pool_size (default 5), leading to use-after-free segfaults (exit code 139) in the native sqlcipher3 C library during multi-threaded operations like user signup. Now defaults to NullPool (each operation creates/closes its own connection) for maximum safety with the native C extension. Also respects the DATABASE_POOL_SIZE setting: if explicitly set >0, QueuePool is used with the configured pool parameters, matching the behavior of other DB paths. Fixes #22258 |
