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?
