Pranav2612000 opened a new issue, #3840:
URL: https://github.com/apache/arrow-adbc/issues/3840
### What happened?
Here's a sample test
```
#[test]
fn test_driver_setup() {
const SNOWFLAKE_DRIVER_NAME: &str = "snowflake";
let mut driver = ManagedDriver::load_from_name(
SNOWFLAKE_DRIVER_NAME,
None,
AdbcVersion::default(),
LOAD_FLAG_DEFAULT,
None,
)
.unwrap();
println!("Driver loaded");
}
```
Here's the output on running the test
```
Finished `test` profile [unoptimized + debuginfo] target(s) in 11.79s
Running unittests src/lib.rs (target/debug/deps/<redacted>)
running 1 test
Driver loaded
```
As you see, the test never completes. Debugging further, I've pinpointed the
issue to the ADBC FFI init function ( FFI_AdbcDriverInitFunc ) (
[here](https://github.com/apache/arrow-adbc/blob/4a3b8eb940a138a7517fbdcf43d7b53692db5130/rust/driver_manager/src/lib.rs#L387)
)
On the same machine, the following
[code](https://github.com/Pranav2612000/snowflake-adbc-test/blob/master/src/main.rs)
works as expected, with a clean shutdown
### Stack Trace
