ArrayBufferView size is not a small enough positive integer. about sipml5 HOT 5 CLOSED

This issue is not relayted to the message content. The sipml5 does not accept 
websocket.opcode == Text frame, but...

http://tools.ietf.org/html/draft-ibc-sipcore-sip-websocket-02#section-4.2
WebSocket messages are carried on top of WebSocket UTF-8 text frames
or binary frames.  The SIP protocol [RFC3261] allows both text and
binary bodies in SIP messages.  Therefore SIP WebSocket Clients and
SIP WebSocket Servers MUST accept both WebSocket text and binary
frames.

Possible solution:




function __tsip_transport_ws_onmessage_for_buffer(data) {
    var o_ragel_state = tsk_ragel_state_create();
    tsk_ragel_state_init_ai(o_ragel_state, data);
    var o_message = tsip_message.prototype.Parse(o_ragel_state, true);

    if (o_message) {
         //--console.debug("recv=%s", o_message.toString());
        o_message.o_socket = this;
        return this.o_transport.get_layer().handle_incoming_message(o_message);
    }
    else {
        console.error("Failed to parse message: %s", data);
        return -1;
    }
}

function __tsip_transport_ws_onmessage(evt) {
    console.debug("__tsip_transport_ws_onmessage");

    if(typeof(evt.data) == 'string') {
        var bb = new (window.MozBlobBuilder || window.WebKitBlobBuilder || window.BlobBuilder)();
        bb.append(evt.data);
        var f = new FileReader(bb.getBlob());
    f.websocket = this;
        f.onload = function(e) {
            __tsip_transport_ws_onmessage_for_buffer.call(f.websocket, e.target.result);
        }
        f.readAsArrayBuffer(bb.getBlob());
    }
    else {
        return __tsip_transport_ws_onmessage_for_buffer(evt.data);
    }
}

The problem with "DOMString" is that SIP message will not be able to contain 
binary data while ArrayBuffer can contain both.
You don't need to write a new function. Try to change the ragel initializer
from:
tsk_ragel_state_init_ai(o_ragel_state, data);
to:
tsk_ragel_state_init_str(o_ragel_state, data);

But sipml5 sends text blob itself. :)

>Try to change the ragel initializer from

Yes, it works! Thank you. Will you add it to project?

    if(typeof(evt.data) == 'string')
        tsk_ragel_state_init_str(o_ragel_state, evt.data);
    else
        tsk_ragel_state_init_ai(o_ragel_state, evt.data);
