PROFILE
Roman Konecny
Worked on the dotnet/runtime repository over four months, focusing on reliability and correctness in core networking and system components. Addressed four targeted bugs, including Unicode-safe URI path handling, HTTP/2 test reliability, a Linux-specific WebSocket memory leak, and OpenSSL 3.5+ test compatibility. Applied C# expertise in code refactoring, memory management, and network programming to improve Unicode preservation in URIs, stabilize HTTP/2 test infrastructure, and ensure proper resource disposal for WebSockets on Linux. Enhanced SSL/TLS test hygiene by aligning with evolving OpenSSL behavior, demonstrating disciplined test maintenance and a methodical approach to system programming and cross-platform software testing.

Jun 1, 2025June 2025 monthly performance summary for dotnet/runtime focused on test reliability and cross-OpenSSL compatibility. Implemented a targeted test-skipping change to reduce flaky or redundant tests in Linux environments with OpenSSL 3.5+ by skipping the SslKeyLogFile_IsCreatedAndFilled test when key logging is enabled by default. This aligns test execution with newer OpenSSL behavior and improves CI stability without sacrificing coverage.

Apr 1, 2025April 2025 monthly summary for dotnet/runtime. Key achievement: fixed a Linux-specific memory leak in HttpListener WebSocket by introducing HttpListenerWrappedWebSocket and ensuring proper disposal. This change prevents leaks when the WebSocket is not explicitly disposed, improving stability for WebSocket-heavy scenarios on Linux and reducing memory pressure in long-running services. Commit reference: b1d93d078659f71068715b5fc5a1843d64395490.
