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.
