March 2026 achievements focused on building a more hermetic, scalable, and reliable CI/build pipeline for the Datadog agent, with strong emphasis on Bazel tooling, caching strategies, cross‑platform reliability, and upgrade readiness. Key features delivered: - Bazel tooling and Gazelle upgrades delivering hermetic Go stringer generation and improved BUILD.bazel generation for proto and stringer tooling. - CI caching and Bazel workflow improvements, including a main-branch cache population workflow, per-job repository caches, and enabling Bazel tests in MQ to reduce cold-start latency. - XDG cache handling and GitHub Actions cache robustness, including XDG_CACHE_HOME abspath validation, stabilized go_mod_tidy cache workflow, and explicit path exclusions to reduce cache churn. - Windows/FIPS Docker build reliability: switched Maven download to Maven Central to ensure reliable dependency resolution. - Bazel 9 readiness: added explicit imports for critical rules (cc_static_library and py_binary) to ease Bazel 9 upgrade and avoid silent failures. Overall impact: The month’s work improved build reproducibility, shortened validation cycles for PRs, and laid groundwork for a smooth Bazel 9 rollout across Linux and Windows. It also reduced cache-related flakiness, improved cross-platform consistency, and increased confidence in hermetic toolchains, accelerating downstream delivery and reliability. Technologies/skills demonstrated: Bazel, Gazelle, Go tooling and stringer integration, GitHub Actions caching, repository caches, cross-platform (Windows/Linux) build reliability, hermetic builds, and incremental upgrade readiness.
