Relative imports not properly parsed

[jyn514]

Steps to reproduce

1. mkdir package
2. echo > package/module.py
3. echo "from .module import *" > package/__init__.py
4. echo "from package import *; print(module)" > package/test.py
5. pylint package --errors-only

Current behavior

No config file found, using default configuration
************* Module package.test
E:  1,29: Undefined variable 'module' (undefined-variable)

Expected behavior

No config file found, using default configuration

pylint --version output

No config file found, using default configuration

I think what's going on is that normally package/module would not be imported and give a name error, but because it's imported in __init__, it's part of the package namespace. This is edge behaviour and probably not something that should be depended on in production.
