Worked on the cloudwego/hertz repository to enhance the reliability of HTTP response handling by focusing on the ResponseReadBodyStream component. Addressed a specific bug related to oversized HTTP responses by adding targeted tests that validate error handling when the Content-Length exceeds 8KB. Employed a test-driven approach using Go, ensuring that the new tests align with existing testing patterns and provide traceability through commit references. This work improved the robustness of the ReadBodyStream logic, helping to catch regressions and maintain correct behavior for large payloads. Demonstrated skills in HTTP protocol handling and software testing within a production-grade codebase.
