Re: [Jd3-devel] Server closes the connection with D3.py

[Jose E. S. <sua...@gv...>]

In the client side, i ´ve two type of connecion : CONNECTION_TCP and  
CONNECTION_TCP_PROXY.
CONNECTION_TCP runs, but CONNECTION_TCP_PROXY not...

I see in the docs..

For debugging :
you can "tandem" on the phantom line to see the message print by the  
subroutine
or start a tread with the -d option

but the debug mode only says..
:d3server -d
Serveur started on pid 0
Starting 2 threads...
One thread started on port 30000
Starting child with D3Client -port 30000 -s 0 -d
One thread started on port 30001
Starting child with D3Client -port 30001 -s 0 -d
Server ready on port 20002
New connection from 192.168.10.226
Connection client on 30000

I´ve reading the code i see this: (d3server line 287)
         *------------------------------------------------------------
         * Send the number of port to the client, if we got one
         *------------------------------------------------------------
         if next.port # "" then
            if next.port < 0 then
               buffer = "-":oconv(abs(next.port),"mr%7")
            end else
               buffer = oconv(next.port,'mr%8')
            end
            if debug then print "Connection client on ":next.port

            %send(fd, buffer, 8 ,0)
         end

        if UnixHost then
           %close(fd)
        end else
           %closesocket(fd)
        end

well... this mean that the protocol closes the connection(therefore  
runs correctly), sending first the new port to continue talking with  
the client... but in the client side don´t respect this behaviour?
Reading the client side, I see that the ptype variable store the  
integer 2,this is the CONNECTION_TCP_PROXY value...but the client side  
dont´t  manages this parameter

class D3Connection:
[...]
    def __initTcp(self):
        newport = self.__port
        sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

        # Try to get the port number of a D3Client
        if self.__type == CONNECTION_TCP :
            try:
                sock.connect((self.__server,newport))
                buf = sock.recv(8)
                newport = int(buf) + 0
                sock.close()
            except:
                print "Connection error to main server " +  
self.__server + ":%i" % newport
                return(D3_ERR)

        self.__port = newport

        try:
           sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
           sock.connect((self.__server,newport))
           self.__socket = sock
        except:
            print "Connection error to D3Client " + self.__server + ": 
%i" % newport
            return(D3_ERR)

        return(D3_OK)
[...]

What is the difference between CONNECTION_TCP and CONNECTION_TCP_PROXY?
