Description

In my code, I tried to use the libsql server via direct HTTP call. Some error message has been raised like "Timed out while openning database connection".

I find the code here https://github.com/tursodatabase/libsql/blob/main/libsql-server/src/connection/mod.rs#L253-L295

And I find seems there is no place to release the Semaphore except to close the current connection?

Research direction

Start at libsql-server/src/connection/mod.rs:253-295, then trace the direct HTTP connection path and the Semaphore's lifecycle. Determine whether the permit is released only when the current connection closes; done means the timeout and concurrent-connection behavior, including the expected release point, are made explicit.
