Hi, Here's another batch of patches to distutils-r1. Aside from some refactoring, it includes the following changes:
1. Lower bounds for most of the build systems were bumped to the lowest stable versions in ::gentoo. This should match upstream requirements better, especially that a few backends have recently added support for license expressions, and poetry-core gained PEP 621 metadata support. 2. FLIT_ALLOW_INVALID is now set to avoid breakage when license validation fails. 3. Support for uv-build backend is added. We hack the package a fair bit, because we don't want to waste time building another uv-build executable that's roughly 50% of dev-python/uv. 4. We use unique build directories for each setuptools invocation now. This avoids issues when a single package is building more than one wheel, and they'd end up all copying files to the same build directory, and setuptools will just keep copying modules from one package to the next... 5. We now make it easier to override the PEP517 backend used. You set DISTUTILS_UPSTREAM_PEP517 to the backend used upstream, and DISTUTILS_USE_PEP517 to the backend you want to use -- and you don't have to edit build-backend in pyproject.toml anymore. Most packages won't need it, and should just continue setting DISTUTILS_USE_PEP517. -- Best regards, Michał Górny Michał Górny (11): distutils-r1.eclass: Bump build system lower bounds distutils-r1.eclass: Set FLIT_ALLOW_INVALID dev-python/uv-build: New package, v0.6.9 distutils-r1.eclass: Support uv-build backend distutils-r1.eclass: Support the legacy "uv" backend too distutils-r1.eclass: Use unique setuptools build directories distutils-r1.eclass: Reflow _distutils-r1_backend_to_key() distutils-r1.eclass: Invert DISTUTILS_USE_PEP517 - backend mapping distutils-r1.eclass: Support overriding PEP517 build backend dev-python/uv-build: Use DISTUTILS_UPSTREAM_PEP517 distutils-r1.eclass: Reflow distutils-r1_python_compile() dev-python/uv-build/Manifest | 1 + .../files/uv-build-0.6.9-use-uv.patch | 18 ++ dev-python/uv-build/metadata.xml | 11 + dev-python/uv-build/uv-build-0.6.9.ebuild | 41 +++ eclass/distutils-r1.eclass | 304 ++++++++++-------- 5 files changed, 236 insertions(+), 139 deletions(-) create mode 100644 dev-python/uv-build/Manifest create mode 100644 dev-python/uv-build/files/uv-build-0.6.9-use-uv.patch create mode 100644 dev-python/uv-build/metadata.xml create mode 100644 dev-python/uv-build/uv-build-0.6.9.ebuild
