[Bug 1311051] Re: python-cffi broken

[Jacek Konieczny]

`__pycache__` usage is not limited to Python3 `*.py` files. That
directory is used by 'compiled' code of python modules, but is a good
place for other similar artifacts. It seems like a great choice for
files 'compiled' by cffi – this way multiple Python interpreter versions
can use python modules from the same directory. And the system 'site-
packages' is not the only place where python modules may be stored.

The problem here is, that there are no cffi-compiled files included for
the 'cryptography.hazmat.bindings' module and cffi tries to compile them
on runtime. It is good it failed – so we can see the packaging problem.

The 'compiled' extension modules should be included in the
'cryptography.hazmat.bindings' and, maybe, the
'cryptography.hazmat.bindings' should be modified not to try to
recompile that.

Here are some hints:

  seems python-cffi is very broken, __pycache__ is imho python3 specific
  way of storing .pyc/.pyo
