Qprocess buffer to small?

[xtreme]

Hello,
I am trying to get a list of information from a program to my qt-program.
When receiving small amounts of data, there is no problem.
However when im receiving 500,000 bytes of tekst-information it crashes. I cannot find a single way to prevent this.
I am trying to buffer by using the following function:

void MainWindow::ViewDirReadStandardOutput()
{
qDebug() << ls->readLine() << ls->size();
if(ls->size() > 0){
ViewDirReadStandardOutput();
}
}

void MainWindow::ViewDirReadStandardOutput()
{
qDebug() << ls->readLine() << ls->size();
if(ls->size() > 0){
ViewDirReadStandardOutput();
}
}

To copy to clipboard, switch view to plain text mode 

I am using qDebug to see how far the program gets, this would be replaced by a QStringlist when working.
Could anybody help me with this?

This is not really how this method should look like... It should be a slot connected to a readyRead() signal and it should contain:

while(ls->canReadLine()){
  qDebug() << ls->readLine();
}

while(ls->canReadLine()){
  qDebug() << ls->readLine();
}

To copy to clipboard, switch view to plain text mode

I have deleted the old code contents of the posted function and added
To the function where the ls process is created:

connect( ls, SIGNAL(readyRead()),
	this, SLOT(storedata()) );

connect( ls, SIGNAL(readyRead()),
	this, SLOT(storedata()) );

To copy to clipboard, switch view to plain text mode 

and

void MainWindow::storedata(){
      while(ls->canReadLine()){
        qDebug() << ls->readLine();
      } 
}

void MainWindow::storedata(){
      while(ls->canReadLine()){
        qDebug() << ls->readLine();
      } 
}

To copy to clipboard, switch view to plain text mode 

However it still crashes after about 400 lines.

Certainly not because of buffer overflow. If the buffer filled, the process would have stopped and waited until you would emptied it. I suggest you take a debugger and see where it crashes.

Thanks for the reply. After debugging it (took a while to find out which debugger was the best) it appeared there was a read error function which made it crash.
