QTcpSocket readyRead and buffer size

[Bitto]

It's 1000000 times better to just leave the data in the socket, and return. The next time this signal is fired, you'll probably have enough. So:

void MyClass::slotConnectedToReadyRead()
{
    // Bad:
    static QByteArray data; // static data is bad
    data += readAll(); // unnecessary copy
    if (data.size() < 256)
        return;
 
    // Good:
    if (bytesAvailable() < 256)
        return;
    QByteArray data = read(256); // local variable is good
}

void MyClass::slotConnectedToReadyRead()
{
    // Bad:
    static QByteArray data; // static data is bad
    data += readAll(); // unnecessary copy
    if (data.size() < 256)
        return;

    // Good:
    if (bytesAvailable() < 256)
        return;
    QByteArray data = read(256); // local variable is good
}
