Hello Python experts, I have a program that uses three processes (invoked by multiprocessing) and several threads. The program is terminated when ^C is typed (KeyboardInterrupt). The main process takes the KeyboardInterrupt Exception and it orderly shutdown the program.
It works fine in normal situation. However, KeyboardInterrupt is not accepted when, for example, the program is stuck somewhere due to error in network. I understand that the KeyboardInterrupt won't be processed until the program moves out from an atomic step in a Python program. Probably this is partly my fault as I use some blocking statements (without timeout) as they should not block the program in normal situation. As the program freezes up, I cannot do anything except killing three processes using kill command. So, I cannot tell which statement is actually blocking when this occurs (and there are many suspects). Is there any good way to deal with this kind of problem? Killing three processes when it hangs is not a fun thing to do. Any suggestions will be greatly appreciated. Best regards, Aki Niimura -- http://mail.python.org/mailman/listinfo/python-list
