PROFILE

Harry Chiang

Worked on the gem5/gem5 repository to enhance both build efficiency and test reliability over a two-month period. Developed a build-system feature in C++ and SCons that introduced the --debug-fission option, enabling split DWARF debug information and reducing binary sizes while ensuring toolchain compatibility through automated checks. Subsequently, improved the test infrastructure by refactoring SerializationFixture in Python to use mkdtemp for per-test temporary directories, addressing race conditions and improving test isolation. Maintained backward compatibility for legacy tests, resulting in more stable CI runs and reducing flaky-test occurrences. Demonstrated skills in build systems, compiler flags, and test engineering.

April 2025 monthly summary focusing on test reliability improvements in the gem5/gem5 repository. Delivered a targeted test infrastructure improvement by refactoring SerializationFixture to use mkdtemp for per-test temporary directories, addressing race conditions and ensuring isolation. Preserved backward-compatible behavior by retaining generateTempDirName for tests requiring non-existent directory names. This work increases CI stability and reduces flaky-test churn, accelerating the release process.
