Local client socket not emitting error when server not running

nitks.abhinav

Hi,

I have a local client socket and it works fine i.e. connects to local (Unix domain) server , receives data.

But when server is not running it does not emit the error signal, below is the code.

Thanks,

void ClientThread::serverConnect()
{
    //Connect to the local notification srever
    socket = new QLocalSocket(this);
    qDebug() << "Client thread: connecting to notification server\n";
    socket->connectToServer("/usr/bin/fortune");
    qDebug() << "Client thread: connected to server";

    connect(socket, SIGNAL(readyRead()), this, SLOT(readMsg()), Qt::DirectConnection);   
    connect(socket, SIGNAL(error(QLocalSocket::LocalSocketError)),
                this, SLOT(displayError(QLocalSocket::LocalSocketError)));
}

void ClientThread::displayError(QLocalSocket::LocalSocketError socketError)
 {

    switch (socketError) {
        case QLocalSocket::ServerNotFoundError:
        qDebug() << "Client thread: The host was not found. Please check the "
                    "host name and port settings.";

            break;
        case QLocalSocket::ConnectionRefusedError:
             qDebug() << "Client thread: The connection was refused by the peer. "
                                        "Make sure the fortune server is running, "
                                        "and check that the host name and port "
                                        "settings are correct.";
            break;
        case QLocalSocket::PeerClosedError:
         qDebug() << "Client thread: peer closed error.";
            break;
        default:
           qDebug() << "Client thread: The following error occurred: " << socket->errorString();
    }
}

have you tried connecting to the disconnected() signal?

Yes , that also does not work, I think disconnected() works when connection is disconnected at run time after successful connection.

Try to put "connect(socket" lines before this one:

socket->connectToServer("/usr/bin/fortune");

Yes it worked, but its strange it should be dynamic. Anyways, Thanks.
