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 webtul
from multiprocessing.connection import Client
a = 0
try:
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 webtul
from multiprocessing.connection import Listener
from 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 = True
listener_th.start()
listener_th.join(timeout=20)
