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.

* pkgs: refactor needless quoting of homepage meta attribute
A lot of packages are needlessly quoting the homepage meta attribute
(about 1400, 22%), this commit refactors all of those instances.

Python envs did not pass through any of the properties the Python
interpreter has. That could be annoying, especially not having
`python.interpreter` which is the path to the interpreter. This commit
fixes the situation and inherit python.passthru.
Thus far all executables in a derivation were wrapped. This commit
only wraps executables in $out/bin. If other scripts need to be wrapped
as well, then one can use wrapPythonProgramsIn.
When tests are disabled, we do not want to pass checkInputs to
stdenv.mkDerivation. This reduces the build requirements and, more
importantly, helps cutting cycles.
The Python interpreters are patched so they can build .pyc bytecode free
of certain indeterminism.
When building Python packages we currently set
```
compiling python files.
in nix store.
DETERMINISTIC_BUILD=1;
PYTHONHASHSEED = 0;
```
Instead if setting these environment variables in the function that
builds the package, this commit sets the variables instead in the Python
setup hook. That way, whenever Python is included in a derivation, these
variables are set.
See also the issue https://github.com/NixOS/nixpkgs/issues/25707.
This commit fixes several issues:
- as reported in https://github.com/NixOS/nixpkgs/issues/24924 it was
possible that the file _sysconfigdata.pyc was generated after the actual
build of the CPython interpreter. We forgot to regenerate that file
during the build. This is now fixed
- the expression of the 3.3 interpreter now also includes some of the
determinism patches even though the output isn't yet reproducible. The
reason for adding them is that this makes the expressions of the
different interpreters more similar.
- references to -dev packages are now also removed in the 3.6 package,
thereby reducing its closure size
Python does add the script's directory into "sys.path". For the case of
"catch_conflicts.py" this means "/nix/store" is added to "sys.path". This can
result in very long delays if the store contains a lot of entries.

From the manual:
> This attribute should be a number, with a higher value denoting a
lower priority. The default priority is 0.
Just passing -5 or -10 wasn't sufficient, so let's make it -100.
