Including the pytest-xdist package automatically configures numprocesses
to $NIX_BUILD_CORES, so specifying these on a package level has become
redundant.
While looking at the sphinx package I noticed it was heavily
undermaintained, which is when we noticed nand0p has been inactive for
roughly 18 months. It is therefore prudent to assume they will not be
maintaining their packages, modules and tests.
- Their last contribution to nixpkgs was in 2019/12
- On 2021/05/08 I wrote them an email to the address listed in the
maintainer-list, which they didn't reply to.
It depends on pyenchant, which is disabled on python2. This results
in:
```
nix-env -iA unstable.python27Packages.pylint
replacing old 'python2.7-pylint-1.9.5'
installing 'python2.7-pylint-1.9.5'
error: pyenchant-3.1.1 not supported for interpreter python2.7
```
Remove it, à la
eb0d5fc3f0
and now it builds again.
Previously it was missing a runtime dependency on setuptools:
[kier@saelli:~/checkouts/nixpkgs]$ $(nix-build -A python27Packages.pylint --no-out-link)/bin/pylint
Traceback (most recent call last):

With this change, the same command now correctly prints pylint's help text.
This only applies to Python 2.
pyenchant is broken on macOS and also no longer actively developed.
pylint has made this an optional dependency that is no longer part of the
default test suite.
