Over a two-month period, contributed to the archlinuxcn/repo project by delivering two targeted features focused on packaging reliability and modernization. Addressed reproducibility in Go module downloads by enabling the -modcacherw flag within the Gatus PKGBUILD, ensuring writable module caches across Linux environments and continuous integration pipelines. Later, upgraded the zeal-git package to Qt6, improving compatibility and performance with the latest Qt libraries while reducing technical debt. The work emphasized build determinism, package management, and system modernization, utilizing skills in CMake, shell scripting, and bash to enhance the repository’s maintainability and alignment with reproducible-build standards. No bugs were reported.
