Traceback on shared objects

When I run pylint2 on a Cython module compiled in-place, it tracebacks trying to parse the compiled shared object as a Python file:

#!python

Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/pylint/lint.py", line 645, in get_astroid
    return MANAGER.ast_from_file(filepath, modname, source=True)
  File "/usr/lib/python2.7/site-packages/astroid/manager.py", line 104, in ast_from_file
    return AstroidBuilder(self).file_build(filepath, modname)
  File "/usr/lib/python2.7/site-packages/astroid/builder.py", line 127, in file_build
    node = self.string_build(data, modname, path)
  File "/usr/lib/python2.7/site-packages/astroid/builder.py", line 133, in string_build
    module = self._data_build(data, modname, path)
  File "/usr/lib/python2.7/site-packages/astroid/builder.py", line 146, in _data_build
    node = parse(data + '\n')
  File "/usr/lib/python2.7/site-packages/astroid/builder.py", line 39, in parse
    return compile(string, "<string>", 'exec', PyCF_ONLY_AST)
TypeError: compile() expected string without null bytes
************* Module pytouhou.formats.anm0
F:  1, 0: <type 'exceptions.TypeError'>: compile() expected string without null bytes (astroid-error)

It happens both using the dotted notation for the module pylint2 pytouhou.formats.anm0 and the file path notation pylint2 pytouhou/formats/anm0.so, while trying to load the pyx or pxd correctly stops with a syntax-error.

curious about that one but doesn't have environment to test it easily. Could you provide minimal source code to reproduce this?

We also experience this with the khmer project.

#!bash

virtualenv test 
source test/bin/activate #these are optional
pip install -U pylint
git clone https://github.com/ged-lab/khmer.git
cd khmer
make all
pylint khmer

[...]

Do not attempt to analyze non python file, eg .so file. Closes #122
