Worked on reliability improvements for the HTTP/2 client close path in the Unity-Technologies/grpc-go repository, focusing on error handling and network programming using Go. Addressed a bug where the client could block indefinitely on broken connections by enforcing net.Conn.WriteDeadline during the close process. Enhanced observability by logging non-nil ReadDeadline errors, making debugging and traceability of close behavior more effective. Expanded automated test coverage to validate that deadlines are correctly set, ensuring robust handling of degraded network scenarios. The work strengthened the client’s resilience and aligned with performance and stability goals, emphasizing thorough testing and careful attention to network reliability.
