#87736 — Root logger sanity

The following code is challenging my sanity, in my understanding of the documentation this should pass, given that getLogger is supposed to return the root logger and the root logger should be called 'root'.  

https://docs.python.org/2/library/logging.html#logger-objects

What am I missing?


from unittest import TestCase
import logging

class LoggingSanityTest(TestCase):

    def test_root_logging_sanity(self):
        assert logging.getLogger() == logging.getLogger('root')

Where do you get the idea that the root logger should be called 'root'?
AFAIU the documentation the root logger is nameless. So

logging.getLogger() will return the root logger while

logging.getLogger('root') will return the logger named 'root'

which are two different loggers.

>>> import logging
>>> logging.getLogger()
<logging.RootLogger object at 0x7fdef71a8630>
>>> _.name
'root'

The root logger is the only logger where

assert logger is logging.getLogger(logger.name)

fails. I can see that this may be a pitfall.
