Jun 1, 2025June 2025 monthly summary for google/android-cuttlefish: Focused on accelerating the build/test cycle through Bazel caching enhancements, Docker image build acceleration, and CI/CD cleanup. Key outcomes include: (1) Bazel caching and CI improvements with disk and remote caches, cache keys, invalidation strategies, and periodic cache recreation across GitHub Actions and Kokoro; (2) Docker image build acceleration by reusing locally built Debian packages in docker-image-check, reducing dependency fetch time; (3) CI/CD cleanup and script refinement, including moving cache-config.env to a common config dir, removing outdated TODOs, and splitting build_package responsibilities for better maintainability; (4) technical refinements such as enabling NASM with Bazel deps for libvpx and using environment-driven defaults for remote_cache_arg and cache_version_arg. Overall impact: faster builds and feedback loops, more deterministic and reusable artifact pipelines, and improved maintainability of CI/CD pipelines.
