I was fighting with a problem all day that was producing multiple messages in my logging output. The problem was related to the fact that I was defining logging handlers multiple times. I found the following posting from a few years ago that related to my problem:
http://groups.google.com/group/comp.lang.python/browse_thread/thread/8a707c289642c668/44f16cf5ba68721f?lnk=gst&q=logging#44f16cf5ba68721f What I did was the following: def initLogging(loggingArea): # create/get logger logger = logging.getLogger("mylogger") logger.setLevel(logging.DEBUG) # setup Handlers if len(logger.handlers) == 0: # create handlers only if there are none sh = logging.StreamHandler() # now add the handlers logger.addHandler(sh) If the logger already has handlers nothing happens, otherwise they're created and added to the logger. Now I can call initLogging ('mylogarea') whereever I need to without getting multiple messages. If you know of a better way to do this let me know... -- http://mail.python.org/mailman/listinfo/python-list
