During October 2025, Dutianxue contributed to the linuxdeepin/lastore-daemon repository by developing an Incremental Update Cache Cleanup Command in Go, focusing on cache management and system programming. This command detects when incremental updates are enabled and purges related cache files and OSTree artifacts, effectively reducing disk usage and managing update bloat. Dutianxue also addressed a logging and compilation issue by correcting a typo in the log output, restoring proper logging functionality and build stability. The work demonstrated a practical approach to command line interface design and bug fixing, resulting in a more reliable and maintainable update workflow for the project.
