[mosquitto-dev] Mosquitto Fail to send large data to websockets

[Manuel Berro Madero <manuelberromadero@xxxxxxxxx>]

I want to send large data (40MB) to websockets but mosquitto does not 
complete the entire file because an unknown reason. Mosquitto starts 
sending but after a few packets it stops. The same thing works under 
normal mosquitto_sub.

I am finding out the reason of why suddenly stops sending, I found the 
function "_mosquitto_write_bytes"

but I can't undestand how does it make that work.  I had similar issue 
in python with send() and sendall()

#file: net_mosq.c

void _mosquitto_write_bytes(struct _mosquitto_packet *packet, const void 
*bytes, uint32_t count)
{
    _mosquitto_log_printf(NULL, MOSQ_LOG_DEBUG, "Testing( %d )", count);

    assert(packet);
    assert(packet->pos+count <= packet->packet_length);

    memcpy(&(packet->payload[packet->pos]), bytes, count);
    packet->pos += count;
}

Where is the socket.send() ??


Regards.
