python 多进程通信模块的简单实现
多进程通信方法好多，不一而数。刚才试python封装好嘅多进程通信模块 multiprocessing.connection。
简单测试咗一下，效率还可以，应该系对socket封装，效率可以达到4krps，可以满足好多方面嘅需求啦。
附代码如下:
client
复制代码 代码如下:#!/usr/bin/python# -*- coding: utf-8 -*-""" download - slave"""__author__ = 'Zagfai'__license__ = 'MIT@2014-02'
import webtulfrom multiprocessing.connection import Client
a = 0try: while True: a += 1 address = ('10.33.41.112', 6666) conn = Client(address, authkey='hellokey') #print conn.recv() d = conn.recv() conn.close()except: pass
print a
server复制代码 代码如下:#!/usr/bin/python# -*- coding: utf-8 -*-""" downloader - master server"""__author__ = 'Zagfai'__license__ = 'MIT@2014-02'
import webtulfrom multiprocessing.connection import Listenerfrom threading import Thread
def listener(): address = ('10.33.41.112', 6666) listener = Listener(address, backlog=100, authkey='hellokey') while True: conn = listener.accept() #print 'connection accepted from', listener.last_accepted try: conn.send({'1':2, '2':'abc'}) except Exception, e: print e finally: conn.close() listener.close()
listener_th = Thread(target=listener)listener_th.daemon = Truelistener_th.start()listener_th.join(timeout=20)
