Chentianyu Tian focused on packaging and build system hardening for the linuxdeepin/dde-shell repository, delivering targeted improvements over a one-month period. He updated build dependencies and package control files, refined versioning, and adjusted build-depends relationships to enhance compatibility and reproducibility across target distributions. Using C++ and Shell, he reorganized file installations and removed unused build flags, simplifying the build process and reducing maintenance overhead. His work in Debian packaging and build systems aimed to streamline future releases and ensure smoother integration. The depth of these changes addressed both immediate build reliability and long-term maintainability for the dde-shell project.
