Upstream Python is moving to pyproject.toml rather than setup.py and
wheels rather than eggs. The main place this is documented is in
PEP-517[1]. Installing packages with setup.py install is deprecated.
We have a choice with the 'kirkstone' LTS release of introducing this
series (and fixing any fall out during the stabilization period) or
living with deprecated Python packaging for the duration of the LTS (at
a minimum 2 years). This seems to be a compelling enough reason to bring
in this series, even if it results in a slight slip of the 'feature
freeze', which is officially tomorrow, Monday 21 Feb, 2022.
This series bootstraps python3-setuptools-native,
python3-flit-core-native, python3-wheel-native and python3-pip-native,
simply unzipping the wheel into PYTHON_SITEPACKAGES_DIR. This allows all
other recipes to be installed with pip, as intended by upstream.
Three new classes are introduced:
(1) flit_core which builds PEP-517 compliant packages which use
flit_core.buildapi as their build-backend.
(2) setuptools_build_meta which builds PEP-517 compliant packages which use
setuptools_build_meta as their build-backend.
(3) pip_install_wheel, which simply installs wheels built by other
classes.
The original setuptools3.bbclass do_compile is modified to
'setup.py bdist_wheel' (from python3-wheel-native) rather than the deprecated
'setup.py build' mechanism.
The original setuptools3.bbclass do_install is modified to
use the pip_install_wheel.bbclass to install wheels with pip rather than
the deprecated 'setup.py install' mechanism.
For pip install, we disable dependency checking (--no-deps) because it
proves to be brittle in our environment without providing full wheel
cache that seems like overhead that we do not need. We also disable
fetching wheels from pypi (--no-index). This is no different than our
normal workflow of requiring dependencies to be defined in a recipe.
Missing from this series is documentation of the new features, classes
and variables (this will be done under separate cover).
Also desired and previously discussed in YP meetings is a helper
function to warn that a recipe which currently inherits setuptools3
but has a pyproject.toml and defines a build-system.build-backend should
instead use of the new PEP-517 classes. This function is still in progress.
During testing, recipes which use python3-setuptools-scm are failing to
determine the version of the python package, For several recipes, the fix
was to use pyproject.toml and PEP-517 build backends. To be sure, other recipes
are still going to fail for the short term, until the root cause can be
determined. This was not seen again in v2 builds.
Another PEP-517 build-backend, poetry.core.masonry.api has been
identified in recipes in meta-python, but not in oe-core. The
python3-poetry-core recipe is WIP, but brings in a number of
dependencies that are perhaps not worth it to bring into oe-core at this
time. Rather we can support these recipes in meta-python?
Fixes in v2 include passing --root=${D} to pip install (rather than --target)
and also passing --prefix so that scripts are (usually) installed in the proper
location. pip install also 'helpfully' overwrites python3 intepreter with
nativepython3
in #!, so add a fix to return the values to what is actually correct (similar
to what is
done in setuptools3.bbclass). Also several recipes still needed
PIP_INSTALL_PACKAGE defined.
Also added self as maintainer of new recipes.
