Python Question

python , launch an external program with ulimit

I need to launch an external program from my python script.
This program crashes, so I need to get a core dump from it.

what can i do?


Check out the python resource module. It will let you set the size of core files, etc., just like the ulimit command. Specifically, you want to do something like

resource.setrlimit(resource.RLIMIT_CORE, <size>)

before launching your target program.

My guess at usage (I haven't done this myself) is:

import resource
import subprocess

command = 'command line to be launched'
# os.system(command) would work, but os.system has been deprecated
# in favor of the subprocess module
