Hi,
I got a problem. I use a 'select' in a loop in the main thread, and
when select return, a new thread will be created to handle the network
event. And if the client send some special string, the thread will
change a global flag to false, so the loop in the main thread will
break. But it never work.
Below is the code:
--------------------- s.py (the server) --------------------------
import socket
import select
import thread
import sys
go_on = True
def read_send(s):
s.setblocking(1)
str = s.recv(1024)
print 'recv:', str
s.send(str)
s.close()
if (str == 'quit'):
go_on = False
print 'User quit...with go_on =', go_on
return
s = socket.socket(socket.AF_INET)
s.bind(('', 9999))
s.listen(5)
s.setblocking(0)
while go_on:
r_set = [s.fileno(),]
r, w, e = select.select(r_set,[],[],0.5)
print 'select returned with go_on =', go_on
for rs in r:
if rs == s.fileno():
ns, addr = s.accept()
print 'socket on', addr, 'has been accepted'
thread.start_new_thread(read_send, (ns,))
s.close()
--------------------- c.py (the client) --------------------------
import socket
import sys
if len(sys.argv) != 3:
print 'usage: python c.py ip port'
sys.exit(-1)
ip = sys.argv[1]
port = int(sys.argv[2])
s = socket.socket(socket.AF_INET)
s.settimeout(5)
s.connect((ip, port))
str = raw_input('please input:')
s.send(str)
str = s.recv(1024)
print 'received:', str
s.close()
--------------------------------------------------------------------------
run s.py first, and then run c.py as:
python c.py 127.0.0.1 9999
and then input 'quit', but the server never end :(
Thank you for your help!
