Server thread inside a qt class (need mutex?)

Question

I made this server class that starts a thread when new connection comes in. It works ok with some cases, but it\'s not very stable. I am trying to solve where it breaks. My

Answer 1

I got my old "the wrong way to do it" code to work. I guess this part was where the error was:

//removed
tcpSocket.disconnectFromHost();
tcpSocket.waitForDisconnected();
emit finished();

...

#include 
#include 
#include "MeshServer.hh"
#include 
#include "TableView.hh"

using namespace  std;

FortuneServer::FortuneServer(QObject *parent)
: QTcpServer(parent)
{

}

void FortuneServer::procesServerString(string serverString){

emit procesServerStringToParent(serverString);

}
void FortuneServer::getStringToThread(string serverString){

emit getStringToThreadSignal(serverString);

}

void FortuneServer::incomingConnection(int socketDescriptor)
{


FortuneThread *serverthread = new FortuneThread(socketDescriptor, this);
//connect(&serverthread, SIGNAL(finished()), &serverthread, SLOT(deleteLater()));


QThread* thread = new QThread;

serverthread->moveToThread(thread);




connect(serverthread, SIGNAL(fromThreadString(string)), this, SLOT(procesServerString(string)));
connect(this, SIGNAL(getStringToThreadSignal(string)), serverthread, SLOT(sendString(string)));
connect(serverthread, SIGNAL(finished()), thread, SLOT(quit()));
connect(serverthread, SIGNAL(finished()), serverthread, SLOT(deleteLater()));
connect(serverthread, SIGNAL(finished()), thread, SLOT(deleteLater()));

thread->start();

}



FortuneThread::FortuneThread(int socketDescriptor, QObject *parent): QObject(parent),   socketDescriptor(socketDescriptor)

{
if (!tcpSocket.setSocketDescriptor(socketDescriptor)) {
    emit error(tcpSocket.error());
    cout<<"socket error"<
