Worked on the openwrt/packages repository to enhance cross-platform build reliability and maintain cleaner dependency management. Focused on improving runtime consistency by updating the time callback signature, ensuring compatibility across diverse environments. Addressed a cross-platform bug by introducing the ts-time-cb-signature patch, which streamlined builds on multiple platforms. Upgraded the lua-openssl dependency to version 0.11.1 and updated the corresponding Makefile, reflecting a commitment to up-to-date and secure dependencies. Additionally, removed an obsolete LuaJIT patch to reduce maintenance overhead and prevent platform divergence. Utilized C programming and build system management skills, emphasizing robust dependency hygiene and sustainable code maintenance practices.
