All, I need to run a third-party binary from a python script and retrieve its output (and its error messages). I use something like >>> process = subprocess.Popen(options, stdout=subprocess.PIPE, >>> stderr=subprocess.PIPE) >>> (info_out, info_err) = process.communicate() That works fine, except that the third-party binary in question doesn't behave very nicely and tend to segfaults without returning any error. In that case, `process.communicate` hangs for ever.
I thought about calling a `threading.Timer` that would call `process.terminate` if `process.wait` doesn't return after a given time... But it's not really a solution: the process in question can sometimes take a long time to run, and I wouldn't want to kill a process still running. I also thought about polling every x s and stopping when the result of a subprocess.Popen(["ps","-p",str(initialprocess.pid)], stdout=subprocess.PIPE) becomes only the header line, but my script needs to run on Windows as well (and no ps over there)... Any suggestion welcome, Thx in advance P. -- http://mail.python.org/mailman/listinfo/python-list
