EasyBuild v4.2.0 Release Notes

Release Date: 2020-04-14 // about 4 years ago

  • 🚀 EasyBuild v4.2.0 is primarily a feature/update release, but also includes various bug fixes.

    🚀 Highlights of the changes in this release include:

    ⚡️ (experimental) support for --try-update-deps, to upgrade dependencies based on available easyconfigs;

    👀 a locking mechanism to prevent two simultaneous installations of the same easyconfig file to the same installation path (see https://easybuild.readthedocs.io/en/latest/Locks.html for more information);

    significant speedup for -D/--dry-run by avoiding useless 'module show' calls;

    ✅ support for creating an index & using it to speed up searching for easyconfigs (see https://easybuild.readthedocs.io/en/latest/Easyconfigs_index.html for more information);

    ➕ additional GitHub integration features:

    • support for targeting the easyblocks and framework repositories with eb --new-pr (via --pr-target-repo)
    • support for including easyblocks from an (open) pull request via --include-easyblocks-from-pr

    - for more information, https://easybuild.readthedocs.io/en/latest/Integration_with_GitHub.html

    📇 probing of external modules for missing metadata that is not provided via an external module metadata file (mostly relevant for integration with the Cray Programming Environment);

    ✅ leveraging the archspec Python library (if it is installed) to show the "code name" of the processor in your system in the output of "eb --show-system-info" and in test reports uploaded to PRs via --upload-test-report;

    👌 support for using templates like %(cudaver)s for the CUDA version (if it's included as direct dependency);

    🛠 fix for UnicodeDecodeError that was raised when reading a patch file that contained non-ASCII characters (if EasyBuild was being run with Python 3);

    🛠 fixed filtering of already installed extensions under --skip (mostly relevant for Python packages installed as bundles of extensions);

    🏗 also support %(installdir)s and %(builddir)s templates for extensions;

    take into account toolchain hierarchy when dumping easyconfig files, to avoid hardcoded subtoolchains in '*dependencies' easyconfig parameters (relevant when using --try-* options);

    take into account dependencies marked as external modules when composing template values like %(pyver)s;

    🚚 deprecate rmtree2 function provided by easybuild.tools.filetools (the remove_dir function should be used instead);
