Мне нужно подключиться к серверу (например, smpp-серверу) и отправлять периодические данные каждые 2 секунды, вот код:
import asyncore, socket, threading, time
class SClient(asyncore.dispatcher):
buffer = ""
t = None
def __init__(self, host):
asyncore.dispatcher.__init__(self)
self.create_socket(socket.AF_INET, socket.SOCK_STREAM)
self.connect( (host, 25) )
print "sending data from __init__"
self.sendCommand("data_init")
self.t = SenderThread(self)
self.t.start()
def sendCommand(self, command):
self.buffer = command
def handle_close(self):
self.close()
self.t.stop()
def handle_read(self):
print self.recv(8192)
def writable(self):
print 'asking for writable ? len='+str(len(self.buffer))
return (len(self.buffer) > 0)
def handle_write(self):
print "writing to socket"
sent = self.send(self.buffer)
self.buffer = self.buffer[sent:]
print "wrote "+str(sent)+" to socket"
class SenderThread(threading.Thread):
_stop = False
def __init__(self, client):
super(SenderThread,self).__init__()
self.client = client
def stop(self):
self._stop = True
def run(self):
counter = 0
while self._stop == False:
counter += 1
time.sleep(1)
if counter == 2:
print "sending data from thread"
self.client.sendCommand("data_thread")
counter = 0
client = SClient('127.0.0.1')
asyncore.loop()
Вот вывод при запуске:
$ python test.py
sending data from __init__
asking for writable ? len=9
writing to socket
wrote 9 to socket
asking for writable ? len=0
sending data from thread

Мой поток отправляет данные на сервер каждые 2 секунды через переменную буфера, но asyncore вызывает доступ для записи и handle_write ровно каждую 1 минуту, я не понимаю, почему он не извлекает буфер сразу после его заполнения из потока?
