I found a bug in logging module in Windows.
I wrote that at here.
https://gist.github.com/2247692
my OS is Windows7 32bit.
C:\Python27>python
Python 2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)] on win
32
Type "help", "copyright", "credits" or "license" for more information.

Maybe some Antivirus program (or Tortoise) is still scanning the file and python cannot rename it.
Can you try to deactivate the antivirus and try again?

Thank you Armaury.
Allowing your advice,I tried that code on other machine(Windows7 without Antivirus).
But it was same result.
Windows says "process cant access to file. that file is using other process.".
And could not rotate the logs.

This is not a logging bug. You called basicConfig with a file name, so the file is opened using a FileHandler and with file name LOG_FILENAME. You then add a RotatingFileHandler with the same name, so the file has two handles referring to it. When the time comes to rotate, the file is still open (with the FileHandler), which is why the rename fails on Windows (though Linux allows it).
Closing as invalid.
