在没有记录器对象的情况下使用python的RotatingFileHandler

Question

I have my own logging system that is not based on a logging object. Can I still enjoy the services of RotatingFileHnadler ? I've tried to define the handler after I set the log file. But I don't see it performed any rotation (no files added named for example mylog.log.1, mylog.log.2 ...) What am I missing?

 handler = RotatingFileHandler(self.fullName+'.debug',mode='a', maxBytes=1, backupCount=1)

logFormatter = logging.Formatter("%(asctime)s [%(levelname)-5.5s] %(message)s")
    fileHandler = RotatingFileHandler('/var/log/blabla.log',
                                  maxBytes=10 * 1000 * 1000,
                                  encoding='utf8',
                                  backupCount=5)
    fileHandler.setFormatter(logFormatter)
    rootLogger = logging.getLogger()
    rootLogger.setLevel(logging.INFO)
    rootLogger.addHandler(fileHandler)
