Worked on the MariaDB/server repository to modernize core dependencies and enhance build stability by upgrading the bundled PCRE2 library to version 10.47. This update improved regular expression performance and expanded functionality, laying a more robust foundation for future development. The technical approach involved careful adjustment of include directories to streamline build integration and organization, which reduced maintenance overhead and facilitated smoother future upgrades. Using CMake and focusing on build systems and library management, the work emphasized clear commit traceability to support audits and potential rollbacks. No major bugs were addressed, as the focus remained on infrastructure and dependency modernization.
