on python 2.6 the following code raises an AttributeError:
#!/usr/bin/env python
import os.path as p
import logging, logging.config
class Logger(object):
def load_config(self):
logging.config.fileConfig(p.join(p.dirname(__file__),'logging.cfg'))
logger = Logger()
logger.load_config()

AttributeError: 'module' object has no attribute 'logger'
From what I understand in the source, the _resolve functions does an
import of the containing module during the parsing of the config file.
In the imported module, the module variable 'logger' is not defined at
that moment and the function fails.
However, I can not see why my code should not work. I want to have a
poor-man's Singleton Logger class ( see Python Cookbook 2nd edition
p.275), so I rebind 'logger' to the only instance of its class.
What's the problem ?
Thanks
Peter
