hand made class with destructor and the logging module

[climb65]

Hello,

I have a handmade class within a python program which uses the logging
module.
This class has a destructor which is expected to log something into my log
file if a crash occurs.
Well, the destructor works well but during the crash, python has already
closed the log file and the reference to the Logger has been set to None.
So, I can't log anything!

How is it possible to solve this problem?

Thanks.

Unfortunately, when a process is about to exit (for whatever reason),
things may not shut down in an order you would like. I'd advise
wrapping your main program in an try: except: block. If you have a
main, function, for example:

import logging, sys

logger = logging.getLogger(__name__)

def main():
#configure logging, say using basicConfig()
try:
# here is whatever your main program is doing now
retcode = 0
except Exception:
logger.exception('Exception raised during processing')
retcode = 1
sys.exit(retcode)

if __name__ == '__main__':
main()
