how to kill subprocess when Python process is killed?
I am writing a Python program that launches a subprocess (using Popen). I am reading stdout of the subprocess, doing some filtering, and writing to stdout of the main process. When I kill the main process (cntl-C) the subprocess keeps running. How do I kill the subprocess too? The subprocess is likey to run a long time. Context: I'm launching only one subprocess at a time, I'm filtering its stdout. The user might decide to interrupt to try something else; the user wants the process and all subprocesses to go away in response to a cntl-C I'm new to python; solution must be for Python 2.5 (windows) to help me. Any help and/or pointers appreciated. -- http://mail.python.org/mailman/listinfo/python-list
