Hello,
I've successfully coded Python to do what I want with a RotatingFileHandler, but am having trouble getting the same behavior via a config file.
I wanted to create one log file each time I run my app, with up to 10 files kept from the last invocations. This was accomplished with
self._logger = logging.getLogger('PDGUI') # We will rotate the files 'manually', so use zero rotate size. handler = logging.handlers.RotatingFileHandler( \ "..\\PDGUI.log", "a", 0, 10) handler.doRollover() # force the next file to be used
formatter = logging.Formatter("%(asctime)s " + \ "%(levelname)s\t%(message)s") handler.setFormatter(formatter) self._logger.addHandler(handler) self._logger.setLevel(logging.INFO)
I'd like to do the same thing with a config file (so that, if this *isn't* the behavior I want, I can change the config file, of course).
I started with a rather plain config file, with the only interesting bit being:
[handler_hand01] class=handlers.RotatingFileHandler level=NOTSET formatter=form01 args=("..\\PDGUI.log", "a", 0, 10,)
But I still have one problem - how do I force the "handler.doRollover()" to happen with the config file? There doesn't seem to be any way to do this in the config file itself, which is OK and perhaps appropriate [BTW, has anyone else noticed that RotatingFileHandler isn't documented in the docs? All the other file handlers have at least a paragraph on their options, but nothing for RFH!]
I can't find any way to do the handler.doRollover() in code, either, if I've started off with a config file. Something like
logging.config.fileConfig(options.logconfig)
# BUGBUG If the config file specifies a RotatingFileHandler, # we need to force a doRollover now, but there's no way! # handler = logging.getLogger().getHandler() # THIS DOESN'T EXIST! handler.doRollover() # force the next file to be used
Ideas, suggestions, etc? It's too bad - with the code method, I can do exactly what I want, but not with the config file.
