In the last week I was working to create script which will read command
from socket, call it, return result, stdout, stderr and kill it after
timeout.
After playing with threads, processes, spawns and popens I found
subprocess module.
To call command I use following construction:
finish=time.time()+self.timeout
self.p=subprocess.Popen(self.command,shell=True,
stdout=subprocess.PIPE,stderr=subprocess.PIPE)
while (self.p.poll()==None) and (time.time()<finish):
pass #FIXME more CPU friendly
result=self.p.poll();
if (result==None):
print "kill!"
os.kill(self.p.pid,9)
return result
then to get its stdout:
self.p.stdout.read()
