Concise monthly summary for 2024-12: Focused on refining the build system for histogram_estimation_accuracy_analysis_program within percona/percona-server-mongodb. Delivered a build-system cleanup by renaming the target from histogram_estimation_accuracy_test to histogram_estimation_accuracy_analysis_program, updating SConscript, and removing source files and library dependencies from the Program definition to signal a shift toward cleaner, managed builds. Eliminated a duplicate target to prevent confusion and potential build failures. These changes reduce maintenance burden, improve build reliability, and enable safer future refactors. Demonstrated strong proficiency with the SCons build system, code hygiene, and repository-level collaboration, delivering clear business value through clearer ownership and faster iteration.
