Hello everyone, we are writing an application that needs some cleanup to be done if the application is quit, normally (normal termination) or by a signal like SIGINT or SIGTERM. I know that the __del__ method exists, but unless I'm mistaken there is no guarantee as of when it will be called, and some objects may have already been released (at lease I've had trouble in the past accessing certain objects from inside __del__, probably since the parent class's __del__ has to be called first, then it's objects are already released by the time I need to do something with them). Another method would be to implement something using the signal module and have a callback that does all the cleanup when the app. is quit/terminated/interrupted and have all the child classes override that with their cleanup code.
What is the community's point of view on the subject? Thanks, Gabriel -- http://mail.python.org/mailman/listinfo/python-list
