This commit adds a Nix-specific module that recursively adds paths that
are on `NIX_PYTHONPATH` to `sys.path`. In order to process possible
`.pth` files `site.addsitedir` is used.
The paths listed in `PYTHONPATH` are added to `sys.path` afterwards, but
they will be added before the entries we add here and thus take
precedence.
The reason for adding support for this environment variable is that we
can set it in a wrapper without breaking support for `PYTHONPATH`.
Patching numpy.distutils used to be required for pythonPackages.cython
to build on darwin. It was later accidentally disabled during one of the
refactorings, but that did not break cython. This change reinstantiates
the patch. It still applies, so it should be low maintenance and it can
still be useful.
Originally introduced in 8970a9c and 1531b5e, these patches were lost in
efbe87f when the CPython version files were merged, likely due to
CPython 3.7 not needing them anymore. These patches should remain
in-tree until CPython 3.5 and 3.6 support is dropped completely.
Found with the diffoscope ( https://diffoscope.org/ ).
The upstream patch for distutils does not apply cleanly to Python
3.7.3's sources. (The patch applies cleanly to Python 3.7.2's sources,
but nixpkgs commit 0ddae82e6a upgraded
Python to 3.7.3.) Fix the patch to make python37 build on macOS.
This changeset allows for cross-compilation of Python packages. Packages
built with buildPythonPackage are not allowed to refer to the build
machine. Executables that have shebangs will refer to the host.
Each time a new major/minor version of CPython was released, a new
expression would be written, typically copied from the previous release.
Often fixes are only made in the current/latest release. By merging the
expressions it's more likely that modifications end up in all versions,
as is likely intended.
This commit introduces one expression for Python 3, and another for 2.7.
These two may also be merged, but it will result in a lot of extra
conditionals making the expression harder to follow.
A common passthru is introduced for CPython and PyPy.
