Month: 2024-11 Overview: - Delivered targeted improvements across haskell/cabal and crawl/crawl focused on business value: clearer development build information, more stable CI, and reduced build noise. Emphasized reliable gating policies, visibility into code provenance, and efficient CI pipelines that support faster iteration cycles. Key features delivered: - cabal: Added git-revision disclosure in development builds via a git-rev flag; cabal --version now shows the Git commit hash and branch when building in development configurations. (commit 247b9f6a81dee8c1366989f0c6fbf763eec38c39) - crawl: CI Build Reliability Enhancement by disabling redundant installation of pkg-config and libpng in CI images, streamlining builds and avoiding conflicts. (commit 0f947df1d059fabbbb373e3c2cbcce6f69676528) Major bugs fixed: - cabal: Mergify commits-behind gating policy adjustment across merge strategies. First commit moves the '#commits-behind=0' check to apply only under the 'merge+no rebase' rule to align with intended behavior when rebase is not permitted; second commit removes the commits-behind condition entirely to revert to prior behavior, ensuring users are warned about pending rebases. (commits 4433a9ef0157dfc39412d9f7335c45d57d87dc5d and c07b5240530b9c48df072fe882b672ef5b89d621) - crawl: Compiler Warning Cleanup for flash_tile by silencing the unused parameter with the UNUSED macro when _WIN32 is not defined, reducing noisy compiler output.
