Error in Python RotatingFileHandler

Question

I'm using logging.handlers.RotatingFileHandler class for logging.

This is how I'm using it.

logging.handlers.RotatingFileHandler(logpath, "a", maxBytes=2500000, backupCount=5)

The log files are named in this format python.log.x where x=1,2..5

The log files are generated.

The problem I see here is

In python.log.5 log file, I'm seeing this entry

2013-06-05 09:58:29,994

In python.log.4 log file, I'm seeing this entry

2013-06-05 09:56:29,994

But this is wrong. The entries are seen reversed where the 2013-06-05 09:58:29,994 should be in python.log.4 log file and 2013-06-05 09:56:29,994 should be in python.log.5 log file.

Answer 1

这必须发生，因为您的日志记录类正在被多个进程使用。
