Python v3 Logging
Question: I could use this code below on Python 2. I tried it on Python 3 and I got an
error. Anyone could explain why?

Code:

    
    
    import logging
    import logging.handlers
    
    LOG_FILENAME = 'poller.log'
    
    # Set up a specific logger with our desired output level
    poll_logger = logging.getLogger('pollerLog')
    
    # Add the log message handler to the logger
    log_rotator = logging.handlers.TimedRotatingFileHandler(LOG_FILENAME, when='d', interval=1, backupCount=5, encoding=None, delay=False, utc=False)
    poll_logger.addHandler(log_rotator)
    
    # Roll over on application start
    poll_logger.handlers[0].doRollover()
    

Error:

    
    
    Traceback (most recent call last):
      File "logR.py", line 10, in <module>
        log_rotator = logging.handlers.TimedRotatingFileHandler(LOG_FILENAME, when='d', interval=1, back
    upCount=5, encoding=None, delay=False, utc=False)
      File "C:\LynxApps\Python31\lib\logging\handlers.py", line 206, in __init__
        t = os.stat(filename)[ST_MTIME]
    NameError: global name 'ST_MTIME' is not defined
    

I checked out the documents below and I don't see any difference:

Python v2 -->
<http://docs.python.org/library/logging.html#timedrotatingfilehandler>

Python v3 -->
<http://docs.python.org/py3k/library/logging.handlers.html?highlight=logging#timedrotatingfilehandler>


Answer: It's a bug in Python 3.1.3 (see the [issue on
bugs.python.org](http://bugs.python.org/issue10810)).

Supposedly it's fixed in Python 3.2.
