What's wrong with my logging configuration

[rambius]

Hello,

I am using python logging and as of today it stopped working. Here is
my program:

#!/usr/bin/env python

import base64
import getpass
import httplib
import logging
import logging.config
import sys
import urlparse


logging.config.fileConfig('logging.config')
logger = logging.getLogger(sys.argv[0])


def main():
from optparse import OptionParser

usage = '%prog -u <user> [options] <url>'
parser = OptionParser(usage=usage)
parser.add_option('-u', '--user',
help='The user that will be authenticated')

(options, args) = parser.parse_args()
if len(args) != 1:
logger.error('Please provide a url')
sys.exit(1)
url = args[0]

if not options.user:
logger.error('Please provide a user')
sys.exit(2)

password = getpass.getpass('Password: ')


if __name__ == '__main__':
main()


Here is my logging.config:

[loggers]
keys=root

[handlers]
keys=console,file

[formatters]
keys=consolefmt,filefmt

[formatter_consolefmt]
format=%(name)-12s: %(levelname)-8s %(message)s
class=logging.Formatter

[formatter_filefmt]
format=%(asctime)s %(name)-12s %(levelname)-8s %(message)s
datefmt=%d/%m/%Y %H:%M:%S

[handler_console]
class=StreamHandler
level=INFO
formatter=consolefmt
args=(sys.stdout,)

[handler_file]
class=FileHandler
level=DEBUG
formatter=filefmt
args=('dav.log', 'a')

[logger_root]
level=NOTSET
handlers=console,file

Yesterday, it was working and I have not touched it - logging has been
working for months. This morning it stopped working and I was
debugging it for half a day and I am clueless. It does not the errors
neither on the console nor in the log file.

I will appreciate any help! Thank you in advance!

Hello,

I am using python logging and as of today it stopped working. Here is
my program:
....

I forgot to give my environment:

$ uname -a

Hello,

I was able to reproduce the problem with even a smaller program:

#!/usr/bin/env python

import logging
import logging.config

logging.config.fileConfig('logging.config')
logger = logging.getLogger('test')

def main():
logger.fatal('test1')
import optparse
logger.fatal('test2')

if __name__ == '__main__':
main()

When I run this program the logger statement after 'import optparse'
does not appear. The first logger statement before optparse does
appear. Has anyone experienced similar behaviour?

Hello Ben,

On what environment did you try it?

I use the same config file (from your first message) and your shorter
program, and I see this output:

=====
test        : CRITICAL test1
test        : CRITICAL test2
=====

This is so strange. If I import optparse outside of main() it works.
If I import it between the two logging statement, the second one does
not appear.

Hello,

I found the culprit. Yesterday I added a file called copy.py. It
clashed with the python built-in module copy and caused that nasty
error.
