QTcpServer - different behvaior in debug & release
-
-
@reezeus said:
I mean when u run in release vs debug.
same pc?Well the actual exe would be different so say the debug was "accepted" and release not.
For some security solutions just the fact that is located in another folder would be
enough.Its seems very odd so just asking if u tested with firewall off, just be sure.
(NetSh Advfirewall set allprofiles state off) -
Didn't get it right indeed: yes debug & release are both tested on the same PC.
Both versions are in the same directory (the one created by default by Qt): one folder for the debug and one folder for release.
Note that the issue arises before I deploy the app, i.e. just by starting the program from within the release folder.
I have tried several clean/run qmake/build all. -
What if u run directly in VS ?

.h file:
#ifndef IPSERVER
#define IPSERVER
#define HEADER_FENSERVEUR#include <QtWidgets>
#include <QtNetwork>
#include "emailoutlook.h"class IPServer : public QWidget
{
Q_OBJECTpublic: IPServer(); void SendToAll(const QString &message); private slots: void NewConnection(); void DataReceived(); void DisconnectClient(); private: EmailOutlook outApp; QTcpServer *server; QList<QTcpSocket *> clients; quint16 sizeMessage;};
#endif // IPSERVER
.cpp file:
#include "ipserver.h"IPServer::IPServer()
{
outApp = EmailOutlook();
server = new QTcpServer(this);
if (!server->listen(QHostAddress::Any, 50869))
{
qDebug() << "Server cound not start" + server->errorString();
}
else
{
qDebug() << "Server has started on port " + QString::number(server->serverPort()) + ". Clients can now connect.";
connect(server, SIGNAL(newConnection()), this, SLOT(NewConnection()));
}sizeMessage = 0;}
void IPServer::NewConnection()
{
//SendToAll("New Client connected");QTcpSocket *newClient = server->nextPendingConnection(); clients << newClient; SendToAll("New Client connected"); connect(newClient, SIGNAL(readyRead()), this, SLOT(DataReceived())); connect(newClient, SIGNAL(disconnected()), this, SLOT(DisconnectClient()));}
void IPServer::DataReceived()
{
QTcpSocket *socket = qobject_cast<QTcpSocket *>(sender());
if (socket == 0)
return;QDataStream in(socket); if (sizeMessage == 0) { if (socket->bytesAvailable() < (int)sizeof(quint16)) return; in >> sizeMessage; } if (socket->bytesAvailable() < sizeMessage) return; QString message; in >> message; SendToAll(message); sizeMessage = 0;}
void IPServer::DisconnectClient()
{
SendToAll("New client disconnected");QTcpSocket *socket = qobject_cast<QTcpSocket *>(sender()); if (socket == 0) return; clients.removeOne(socket); socket->deleteLater();}
void IPServer::SendToAll(const QString &message)
{
QByteArray paquet;
QDataStream out(&paquet, QIODevice::WriteOnly);out << (quint16) 0; out << message; out.device()->seek(0); out << (quint16) (paquet.size() - sizeof(quint16)); for (int i = 0; i < clients.size(); i++) { clients[i]->write(paquet); }}
The IPServer class is initialized from another class:
IPServer *myServer;
myServer = new IPServer(); -
ok.
This code can someone else run and see if it can reproduced on other pc? -
