New submission from Mohammad Al <mramah...@hotmail.com>:
It seems that RotatingFileHandler is experiencing an issue when
attempting to rotate log files under Windows. The following errors are
received:
Traceback (most recent call last):
File "C:\Python25\lib\logging\handlers.py", line 73, in emit
if self.shouldRollover(record):
File "C:\Python25\lib\logging\handlers.py", line 147, in
shouldRollover
self.stream.seek(0, 2) #due to non-posix-compliant Windows feature
ValueError: I/O operation on closed file
Traceback (most recent call last):
File "C:\Python25\lib\logging\handlers.py", line 73, in emit
if self.shouldRollover(record):
I tried the code on Python 2.5.2 and 2.5.4 under Windows XP SP 2, with
the same results. To reproduce run the attached scripts few times. The
first time the handlers attempt to rotate the log files the error
message above is received.
In addition to crashing the application, log files are getting lost as
a result, which is a serious issue.
I have seen few complaints about this issue, but tickets were closed
without a real resolution to the issue (unless I missed something)
