[Interest] QtMqtt

[Filip Piechocki]

Hi,
Was playing a bit with QtMqtt and written some example publisher that
shares files from a specific directory. Each file contents is sent as a one
message on /dirName/fileName topic so a subscriber subscribes on /dirName/+

Along the files there was an 35MB mp4 file (so way below MQTT's ~256MB
limit). And it was not sent. I've debugged this and the cause seems to be
data.constData() in QMqttControlPacket::appendRaw() - m_payload.size() does
not change after append while it was appending 35MB bytearray. Removing
.constData() solves the issue - data is properly appended to payload and
subscriber got this message. Is there any reason for constData() there?
Same in append() - also constData is used there.

Another thing is that QMqttConnection::writePacketToTransport() checks if
_any_ bytes were written to QIODevice and what about case where actually
written byte count is _less_ than what we wanted to write?

BR,
Filip
