During a two-month period, KDV enhanced the facebook/buck2-prelude repository by focusing on build system optimization and developer tooling using Bzl and Starlark. KDV first improved build correctness in the dist_lto workflow by refactoring the build stamping process, ensuring that artifact invalidation occurred reliably in distributed builds. The solution involved moving stamping to the final step within cxx_gnu_dist_link and cxx_link_into code paths, addressing artifact freshness issues. In the following month, KDV delivered a performance optimization feature that preferred local execution for build stamping and section cleanup, reducing remote execution overhead and accelerating build times for large binaries across multiple scripts.

Jan 1, 2025January 2025 (facebook/buck2-prelude): Focused on strengthening build correctness and artifact invalidation in the dist_lto workflow. Implemented a targeted bug fix by moving the build stamping step to the final stage of the dist_lto action, ensuring stamped artifacts are correctly invalidated by subsequent steps. This change was applied to the cxx_gnu_dist_link and cxx_link_into code paths, improving reliability of distributed builds and artifact freshness across the pipeline.
