2022-05-19 –, Kirkstone
Upstream Python has deprecated ‘distulils’ and is moving towards ‘pyproject.toml’ instead of ‘setup.py’. In this talk you will learn what changed in the Yocto Project classes and recipes for Python packages in the 4.0 ‘kirkstone’ release. You will also learn about how to look at an upstream ‘pyproject.toml’ and determine which of the new classes to use instead of ‘setuptools3’. We will also discuss recipes for packages that add Rust extensions for Python.
Upstream never stops moving and we need to ride the wave of change. With the deprecation of ‘distutils’ in Python 3.10 (slated for removal in Python 3.12), we need to understand how to use ‘setuptools’ instead. As if that wasn’t enough, with the implementation of PEP-517 and related changes comes the new ‘pyproject.toml’ standard as a replacement for ‘setup.py’. Python packages are no longer distributed as “eggs”, but are now only distributed as ‘sdist’ (source tarball) or ‘wheel’ (installable packages). Meanwhile C-extensions are not the only kid in town, Rust extensions are beginning to be implemented, such as in ‘python3-cryptography’, Hold onto your seats while we take a quick tour of the new world of Python recipes in Yocto Project!
