Python Distributed Computing (жұмыс істейді)

Мен жаңа кодты орналастыру үшін ескі ағынды қолданамын, сол мәселені шешуге тырысамын. Қауіпсіз тұздық дегеніміз не? бұл?

sock.py

from socket import socket
from socket import AF_INET
from socket import SOCK_STREAM
from socket import gethostbyname
from socket import gethostname

class SocketServer:
  def __init__(self, port):
    self.sock = socket(AF_INET, SOCK_STREAM)
    self.port = port
  def listen(self, data):
    self.sock.bind(("127.0.0.1", self.port))
    self.sock.listen(len(data))
    while data:
      s = self.sock.accept()[0]
      siz, dat = data.pop()
      s.send(siz)
      s.send(dat)
      s.close()

class Socket:
  def __init__(self, host, port):
    self.sock = socket(AF_INET, SOCK_STREAM)
    self.sock.connect((host, port))
  def recv(self, size):
    return self.sock.recv(size)

pack.py

#http://stackoverflow.com/questions/6234586/we-need-to-pickle-any-sort-of-callable
from marshal import dumps as marshal_dumps
from pickle import dumps as pickle_dumps
from struct import pack as struct_pack

class packer:
  def __init__(self):
    self.f = []
  def pack(self, what):
    if type(what) is type(lambda:None):
      self.f = []
      self.f.append(marshal_dumps(what.func_code))
      self.f.append(pickle_dumps(what.func_name))
      self.f.append(pickle_dumps(what.func_defaults))
      self.f.append(pickle_dumps(what.func_closure))
      self.f = pickle_dumps(self.f)
      return (struct_pack('Q', len(self.f)), self.f)

unpack.py

from types import FunctionType
from pickle import loads as pickle_loads
from marshal import loads as marshal_loads
from struct import unpack as struct_unpack
from struct import calcsize

#http://stackoverflow.com/questions/6234586/we-need-to-pickle-any-sort-of-callable

class unpacker:
  def __init__(self):
    self.f = []
    self.fcompiled = lambda:None
    self.sizeofsize = calcsize('Q')
  def unpack(self, sock):
    size = struct_unpack('Q', sock.recv(self.sizeofsize))[0]
    self.f = pickle_loads(sock.recv(size))
    a = marshal_loads(self.f[0])
    b = globals() ##
    c = pickle_loads(self.f[1])
    d = pickle_loads(self.f[2])
    e = pickle_loads(self.f[3])
    self.fcompiled = FunctionType(a, b, c, d, e)
    return self.fcompiled

test.py

from unpack import unpacker
from pack import packer
from sock import SocketServer
from sock import Socket
from threading import Thread
from time import sleep

count = 2
port = 4446

def f():
  print 42

def server():
  ss = SocketServer(port)
  pack = packer()
  functions = [pack.pack(f) for nothing in range(count)]
  ss.listen(functions)

if __name__ == "__main__":
  Thread(target=server).start()
  sleep(1)
  unpack = unpacker()
  for nothing in range(count):
    print unpack.unpack(Socket("127.0.0.1", port))
