[PATCH 00/19] Python PEP-517: build wheels and installw with pip

[PATCH 00/19] Python PEP-517: build wheels and installw with pip

[Tim Orling]

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.

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?

[PATCH 01/19] python3-wheel: move 0.37.0 from meta-python

[Tim Orling]

This is one of the "new build tools" which are part of pypa (Python
Packaging Authority) toolchain.

Wheels are the official delivery mechanism for Python packages, replacing
the now deprecated Eggs (egg-info).

[PATCH 02/19] python3-flit-core: add recipe for 3.6.0

[Tim Orling]

This is the core of one of the "new build system" tools, although not
officially part of the pypa (Python Packaging Authority) repositories,
it is an increasingly common build tool (e.g. typing_extensions and
tomli) as declared in pyproject.toml for said packages.

This package provides a very simple bootstrapping method that builds
the source tarball (build_sdist) and a wheel (build_wheel).

Wheels are the official vehicle for delivering Python packages now.
Eggs (egg-info) are deprecated and will increasingly go away.

[PATCH 03/19] python3-flit-core: simplify

[Tim Orling]

Upstream provides a build_dists.py which can be used to bootstrap
building of the sdist and wheel.

Bootstrap -native by simply unzipping the wheel to
PYTHON_SITEPACKAGES_DIR.

Use pip to install the wheel for target.

[PATCH 06/19] pip_install_wheel.bbclass: add helper class

[Tim Orling]

Provide a helper class to use pip to install wheels built by either
bdist_wheel or a PEP-517 backend.

By passings --no-deps and --no-index we avoid finicky dependency
checking (pip expects wheels in its cache) and avoid trying to fetch
wheels from pypi.org. This is basically the same behavior we have now,
the dependencies should be declared in the recipe.

[PATCH 08/19] python3-pip: inherit setuptools_build_meta

[Tim Orling]

Upstream provides a pyproject.toml which declares setuptools.build_meta
as the backend for PEP-517 packaging.

We bootstrap the -native installation by simply unzipping the wheel to
PYTHON_SITEPACKAGES_DIR, so that all other recipes can use pip to
install wheels (as intended by upstream).

Hi,

Subject: [OE-core] [PATCH 00/19] Python PEP-517: build wheels and installw with pip

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.

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?
