Worked on enhancing the robustness of Unix domain socket handling in the microsoft/garnet repository, focusing on backend development with C#. Addressed a bug by implementing a guard clause in the UnixDomainSocketEndPoint to validate the UnixSocketPath, ensuring that null or whitespace values are rejected early. Developed targeted unit tests to confirm that an ArgumentNullException is thrown with a clear, precise message when the UnixSocketPath is missing. These improvements refined error handling and provided more actionable feedback for developers configuring Unix domain sockets, ultimately reducing runtime errors and streamlining troubleshooting. Emphasized error handling and unit testing throughout the process.
