[Python-projects] visit_import bug

[Robert Kirkpatrick]

Hi Guys,

I run into this error:

    module = node.infer_name_module(parts[0]).next()
AttributeError: Import instance has no attribute 'infer_name_module'



But if I change the section of visit_import() in variables.py to comment out
the try/except, I can run pylint ok:

    def visit_import(self, node):
        """check modules attribute accesses"""
        for name, _ in node.names:
            parts = name.split('.')
            #try:
            #    import pdb; pdb.set_trace();
            #    module = node.infer_name_module(parts[0]).next()
            #except astng.ResolveError:
            #    continue
            continue
            self._check_module_attrs(node, module, parts[1:])


I noticed in the log that this was worked on in revision 144 but I have no
idea what this code actually does or how to address it other than what I
did.

I also don't know if there is something weird with the code on my end or if
my code is highlighting a bug.

Any advice?

Cheers,
Rob
