New "module has no attribute" errors in 0.710 #7030
Description
This is a change in behaviour I've noticed in 0.710. I can't help but think it's so simple that I'm obviously doing something very wrong, but I can't obviously see what. My apologies for wasting your time if it is user error! None of the other checking/linting tools I've tried warn about any issues here.
Here's a reproducer for what I'm seeing:
(py3.6) e:\tmp\mypy-issue>cat foo.py
from bar import qaz
print(qaz())
(py3.6) e:\tmp\mypy-issue>cat bar\__init__.py
from bar.baz import qaz
__all__ = [
'qaz',
]
(py3.6) e:\tmp\mypy-issue>cat bar\baz.py
def qaz() -> int:
return 42
(py3.6) e:\tmp\mypy-issue>python --version
Python 3.6.4
(py3.6) e:\tmp\mypy-issue>python foo.py
42
(py3.6) e:\tmp\mypy-issue>pip install -q "mypy<0.710"
(py3.6) e:\tmp\mypy-issue>mypy --version
mypy 0.701
(py3.6) e:\tmp\mypy-issue>mypy --strict .
(py3.6) e:\tmp\mypy-issue>pip install -q "mypy==0.710"
(py3.6) e:\tmp\mypy-issue>mypy --version
mypy 0.710
(py3.6) e:\tmp\mypy-issue>mypy --strict .
foo.py:1: error: Module 'bar' has no attribute 'qaz'
(py3.6) e:\tmp\mypy-issue>
Let me know if you need any more information.
Thanks!
