This hardcoded list of CFFI extension modules gets stale when PyPy adds
more, but fortunately the main translation step already builds these now
(hack_for_cffi_modules in pypy/goal/targetpypystandalone.py).

Wrappers already included `PYTHONNOUSERSITE=1`, but now this env var is
also set in the Python setup hook. This improves purity in case of
non-sandboxes builds and nix-shell.
When a Python script has the extension `.py`, bytecode is generated.
Typically, executables in bin have no extension, so no bytecode is
generated. However, some packages do provide executables with
extensions, and thus bytecode is generated.
28299f669a introduced the first Python
packages having multiple outputs. The required outputs were not picked
up by `python.buildEnv` (#31857).
This commit modifies `python.buildEnv` so that it always includes the
$out output and thus fixes#31857.
Python libraries or modules now have an attribute `pythonModule = interpreter;` to indicate
they provide Python modules for the specified `interpreter`.
The package set provides the following helper functions:
- hasPythonModule: Check whether a derivation provides a Python module.
- requiredPythonModules: Recurse into a list of Python modules, returning all Python modules that are required.
- makePythonPath: Create a PYTHONPATH from a list of Python modules.
Also included in this commit is:
- disabledIf: Helper function for disabling non-buildPythonPackage functions.
This continues #23374, which always kept around both attributes, by
always including both propagated files: `propgated-native-build-inputs`
and `propagated-build-inputs`. `nativePkgs` and `crossPkgs` are still
defined as before, however, so this change should only barely
observable.
This is an incremental step to fully keeping the dependencies separate
in all cases.
In the maintenance release bump in
90059701a8 a certain change to /test/ was
backported from Python 3:
- bpo-30207: To simplify backports from Python 3, the test.test_support
module was converted into a package and renamed to test.support. The
test.script_helper module was moved into the test.support package.
Names test.test_support and test.script_helper are left as aliases to
test.support and test.support.script_helper.
libffi needs a patch to actually work on aarch64 (or the cffi Python package
fails its testsuite). Of course the bundled version of libffi has the
same bug, so don't use the buggy version on aarch64.
Python3 already uses the system libffi on all platforms. I don't know
why Python2 doesn't.
While we tell pip not to fetch (with the `--no-index` option),
`setuptools` can do so itself. In the past we used a `distutils.cfg`
with `allow-hosts = None` to prevent setuptools from fetching itself.
This was removed when we started building wheels in
2562f94de4e4fd2ddc677187fa2e2848L69.
The `dist-utils.cfg` code was still there, and adding it to
`buildInputs` is sufficient.
Tested with python.pkgs.passlib by removing the `checkInputs` / `nose`.
test.{support, regrtest} are the internal packages cpython
developers use to write tests.
Although they are not public and the API may change/break
some developers use these packages to write tests for their
(3rd party) software.
The derivations for cpython now only remove the actual tests
but leave the packages in place that are used to write them.

Symbolic links were added pointing to the executables that end with 3 as
part of the Python 2 to 3 migration. At some point I disabled ensurepip
but forgot to remove this symbolic link.
