Hi ! I want to create a Process Pool Object. I can hold started processes, and can communicate with them.
I tryed with many ipc methods, but every of them have bug or other problem. Sockets are unavailabe (because Windows Firewall hold them). I think I will use pipe. The object's pseudocode: while not Quit: CheckProcessOutputs; ProcessReceivedData; SendDataToSubProcesses; if NoMoreData: Quit=1 If I used pipes and subprocess module in Windows, I got big freezes, and deadlocks. Main proc: subprocpipe.write('aaaa\n') subprocpipe.readlines() Sub proc: input=sys.stdin.readlines().strip() print input+'!!!' It is working. But when I move this client code to cycle, I got deadlock. while not Quit: input=sys.stdin.readlines().strip() print input+'!!!' Quit=input=='q' Why ? Why I cannot create cyclic communication with client ? Subprocess must "staying alive" (don't die), and need to stay in reuseable state ? Simply: subprocess pool needed !!!
