rawsocket can't join (crossbar version 0.10.3)

[Rosa Lisin]

Hello Tobias,

I am trying to run hello.cpp example with the lates versions on msgpack and autobahnCpp, but joining realm fails, here is the crossbar error message:

2015-04-09 06:31:21-0700 [Router      14044] failing RawSocket connection - message length exceeded: message was 2146566144 bytes, but current maximum is 131072 bytes

2015-04-09 06:31:21-0700 [Router      14044] WAMP-over-RawSocket connection lost: reason = '[Failure instance: Traceback (failure with no frames): <class 'twisted.internet.error.ConnectionDone'>: Connection was closed cleanly.

Please let me know what is it I am missing.

The following warning was produced by the compiler while building the project. Not sure if it has anything to do with the problem, but just FYI:

autobahn_impl.hpp: In instantiation of ‘void autobahn::session<IStream, OStream>::start() [with IStream = boost::asio::basic_stream_socket<boost::asio::ip::tcp>; OStream = boost::asio::basic_stream_socket<boost::asio::ip::tcp>]’:

main.cpp:89:30:   required from here

autobahn_impl.hpp:65:27: warning: overflow in implicit constant conversion [-Woverflow]

       m_buffer_msg_len[1] = 0xF2; // we are ready to receive messages up to 2**24 octets and encoded using MsgPack

Thanks,

Rosa

Hi Rosa,

Are you running the latest version (trunk from GitHub) of
_AutobahnPython_ also?

Can you double check?

Because

(python279_1)oberstet@thinkpad-t430s:~/scm/crossbar/crossbar$ python
Python 2.7.9 (default, Jan 18 2015, 21:40:29)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> val = 2146566144
>>> import struct
>>> struct.pack("!I", val)
'\x7f\xf2\x00\x00'

This is exactly the initial handshake bytes sent

https://github.com/tavendo/AutobahnCpp/blob/master/autobahn/autobahn_impl.hpp#L64

And the _old_ AutobahnPython code will interpret that as a message
length, which exceeds the default of 128k.

Cheers,
/Tobias
