python3: Add Py3Build/InstallBuildDepends recipe

2022-03-17T18:38:19Z

This adds a recipe, Py3Build/InstallBuildDepends, that installs the requirements listed in HOST_PYTHON3_PACKAGE_BUILD_DEPENDS. This allows other (non-Python) packages to install host Python packages by calling this recipe, without having to know the internals of python3-package.mk. This also updates apparmor to call this recipe. Signed-off-by: Jeffery To

python: Use locked for host pip

This also removes PKG_BUILD_PARALLEL:=0 that was added for packages that use HOST_PYTHON3_PACKAGE_BUILD_DEPENDS. Signed-off-by: Jeffery To

python3: Use hash-checking mode when installing host pip packages

2020-08-17T15:05:49Z

In hash-checking mode[1], pip will verify downloaded package archives (source tarballs in our case) against known SHA256 hashes before installing the packages. As a consequence, this requires the use of requirements files[2] and pinning packages to known versions. The syntax for package Makefiles has changed slightly; HOST_PYTHON3_PACKAGE_BUILD_DEPENDS no longer accepts requirement specifiers like "foo>=1.0", only requirements file names (which are the same as package names in the most common case). This also updates affected packages, in particular: * python-zipp: "setuptools_scm[toml]" has been split into "setuptools-scm toml" to reuse the requirements file for setuptools-scm (the extra depends installed by "setuptools_scm[toml]" is toml). * python-pycparser: This previously used ply 3.10, whereas the requirements file will now install 3.11.

python-packages: Disable parallel build when host pip is needed

2020-06-30T07:43:01Z

This adds PKG_BUILD_PARALLEL:=0 to packages that depend on host Python packages (HOST_PYTHON3_PACKAGE_BUILD_DEPENDS), because installing packages with multiple concurrent pip processes can lead to errors or unexpected results[1]. This also: * Move HOST_PYTHON3_PACKAGE_BUILD_DEPENDS definitions to before python3-package.mk is included * Update Python folder readme to include PKG_BUILD_PARALLEL:=0 [1]: https://github.com/pypa/pip/issues/2361 Signed-off-by: Jeffery To

python: Fix relative links in readme

2020-06-11T08:36:38Z

This also removes a link to pypi.org; the previous sentence already links to pypi.org, a second link in the same paragraph isn't necessary. Signed-off-by: Jeffery To

python: Remove references to variants in readme

2020-06-11T08:23:49Z

Build variants are no longer necessary. Signed-off-by: Jeffery To

python3: Add script to help find standard library dependencies

2020-05-14T15:38:24Z

This adds a script that searches a Python package's source code to find imports for separately-packaged standard library modules. The script can be run by calling make with the configure target and "PY3=stdlib V=s" arguments, e.g. make package/python3-lxml/configure PY3=stdlib V=s This also updates the readme on how to call this script, as well as more information on Python package dependencies in general.

python: Update readme

2020-04-03T19:09:25Z

* Replace the Python 2 pending removal notice/schedule with a brief message about the removal * Replace mentions of "Python & Python 3" with just "Python" (references to the version number are kept only in cases where it is necessary) * Update Makefile example code to use Python 3 conventions/names Signed-off-by: Jeffery To
