Worked on enhancing the lifecycle management of AwaitableUvicornServer within the singlestore-labs/singlestoredb-python repository, focusing on backend reliability for Python-based UDF applications. Addressed double initialization issues in run_udf_app by consolidating fixes and introduced a shutdown() API to enable graceful termination of long-running services. Leveraged Python, Asyncio, and Uvicorn to centralize lifecycle control, reducing runtime errors and improving maintainability. Also corrected a minor typo in the StdoutSuppressor usage example to clarify documentation for developers. This work improved the stability and developer experience of Uvicorn-based UDF apps by ensuring clean shutdowns and robust server management in production environments.
