During December 2024, Eric Kerber focused on stabilizing test infrastructure within the bazelbuild/rules_apple repository by addressing a bug in the archive_contents_test macro. He improved the macro’s robustness by refining how script paths are interpreted, ensuring they are resolved as labels rather than raw paths. This adjustment, implemented using Starlark and leveraging Bazel’s build system capabilities, enhanced the reliability and determinism of test target definitions. By reducing the occurrence of mis-resolved script paths, Eric’s work contributed to fewer flaky tests in continuous integration, supporting faster feedback cycles and more maintainable code for developers working with Apple rule sets.
