vinay: I understand your preference of dictConfig over fileConfig as
maintainer. But as an application developer I want to provide my user an easy
way to adjust logging herself. In the end of the day she is the one knowing
what has to be logged in which place. Therefor, having something like
fileConfig is essential.
david: The modified configuration can be passed to fileConfig via a StringIO
instance.
The downside is that ConfigParser instances with e.g. 'allow_no_value' set to
True are currently difficult to handle – e.g.:
>>> sys.version
'3.2.3 (default, Jun 25 2012, 23:10:56) \n[GCC 4.7.1]'
>>> cp = configparser.ConfigParser(allow_no_value=True)
>>> cp.read_string('[foo]\nbar')
>>> buf = io.StringIO()
>>> cp.write(buf)
>>> buf.seek(0)
0
>>> logging.config.fileConfig(buf)

1082 self._join_multiline_values()

ParsingError: Source contains parsing errors: <???>

Hence, logging.config.fileConfig should at least provide a way to pass in
arguments for the ConfigParser initialization. Anyways, I think it is much
cleaner to provide a function which gets the configuration directly from the
ConfigParser instance.
