python change max limit recv buffer in UDPServer

buffer, python, socketserver, udp

Solution

Finally, I found it in baseserver python source code :

480 class UDPServer(TCPServer):
481 
482    """UDP server class."""
483
484    allow_reuse_address = False
485
486    socket_type = socket.SOCK_DGRAM
487
488    max_packet_size = 8192

My modified main (see server.max_packet_size )

if __name__ == '__main__':    
    server = SocketServer.UDPServer((HOST, LISTEN_PORT), MyUDPHandler)
    server.max_packet_size = 8192*2
    server.serve_forever()

Problem

I use UDPServer based on BaseServer to receive frag UDP packets . But some packets are larger than 8192 bytes(@handle method, print len(data)), and I can't use them correctly. My original code: ``` class MyUDPHandler(SocketServer.BaseRequestHandler): def handle(self): global arr_len_recv data = self.request[0].strip() socket = self.request[1] s_recv_paylaod_len = len(data) print "s_paylaod",binascii.hexlify(data) if __name__ == '__main__': server = SocketServer.UDPServer((HOST, LISTEN_PORT), MyUDPHandler) tmp = threading.Thread(None, loop_send, None,(param,server) , {}) tmp.daemon=True tmp.start() poll=0.1 server.serve_forever(poll) ``` So I RTFM BaseServer,UDPServer,TCPServer. python SocketServer documentation I found in SocketServer.TCPServer Example ``` class MyTCPHandler(SocketServer.BaseRequestHandler): def handle(self): self.data = self.request.recv(1024).strip() ``` But self.request doesn't have recv method If you have any solution to fix it or to change max limit of recv buffer.
