Network / [UPD3] Disconnect loads CP a lot

« on: June 09, 2013, 06:28:24 pm »

Hi.
I am completly newbie in network programming, so got some problems in my project.
Here is some code.
Client:

if (socket.connect("127.0.0.1", 12312) != sf::Socket::Done)
{
        cout << "ERROR1" << endl;
}

sf::Packet packetSend;
packetSend << "mapNameRequest";
if (socket.send(packetSend) != sf::Socket::Done)
{
        cout << "ERROR2" << endl;
}

while (mapName == "")
{
        sf::Packet packetReceive;
        socket.receive(packetReceive);
        packetReceive >> mapName;
}

//breakpoint
packetSend << "gameSessionNameRequest";
if (socket.send(packetSend) != sf::Socket::Done)
{
        cout << "ERROR2" << endl;
}

while (gameSession.getGameSessionName() == "")
{
        string msg;
        sf::Packet packetReceive;
        socket.receive(packetReceive);
        packetReceive >> msg;
        gameSession.setGameSessionName(msg);
}
 

Server:

listener.listen(PORT);

//Check requests
sf::Packet packetReceive;
string msg;
while(!quit)
{
        if (listener.accept(socket) != sf::Socket::Done)
        {
                cout << "ERROR2" << endl;
        }

        if (socket.receive(packetReceive) != sf::Socket::Done)
        {
                cout << "ERROR3" << endl;
        }

        if (packetReceive >> msg)
        {
                if (msg == "mapNameRequest")
                {
                        sf::Packet packetSend;
                        packetSend << gameMap;
                        if (socket.send(packetSend) != sf::Socket::Done)
                        {
                                cout << "ERROR4" << endl;
                        }
                }

                if (msg == "gameSessionNameRequest")
                {
                        sf::Packet packetSend;
                        packetSend << gameSession.getGameSessionName();
                        if (socket.send(packetSend) != sf::Socket::Done)
                        {
                                cout << "ERROR4" << endl;
                        }
                }
        }
}
 

The problem is in client code. The first request is okay,client can receive mapName.
But after "//breakpoint" there are some porblems.
Client freezes at second "while" cycle. It cant receive "gameSessionNameRequest".
Sorry if question is too stupid.

Thanks.
