[Spice-devel] Adding SPICE support to Guacamole - spice-glib

[Nick Couchman]

Hey, everyone,
I'm a contributor to the Guacamole project, and am currently working on
adding support for the SPICE protocol to Guacamole. If you haven't heard of
Guacamole, it is a protocol and associated software components for making
various remote desktop interfaces available via native HTML5 in browsers. I
realize that there is already a spice-html5 client, but, for various
reasons, we'd like to add the SPICE support to Guacamole, as well.

Within Guacamole, the clients for the individual protocols are implemented
in a daemon - guacd - that is written in C. It accesses the various remote
desktop protocols that we support (VNC, RDP, SSH, and Telnet, today) and
does the translation to the Guacamole protocol. So, I am attempting to
write the SPICE client for this using the spice-glib library.

I'm running into an issue with the code I've written thus far. I've
followed API documentation and some code examples, and I have it to where
I'm configuring all of the required pieces - hostname/IP, tls-port,
password, etc. I've set up the handlers for the session (channel-event) and
for the channels. When I attempt to connect, the SPICE client starts up,
the session starts/connects, and I see the main channel get created, but
the connection never progresses after that. As far as I can tell, it
doesn't even try any sort of connection to the SPICE server - I don't see
any network traffic going to the SPICE server, and it never progresses past
that point. I'm not seeing any errors - nothing that indicates it's tried
and failed, or is expecting additional input, or anything like that.

I'm happy to share code if anyone is interested in looking at what I've
done so far, or if anyone has any generic hints as to what I might check or
resources that are helpful in writing a C-based client for SPICE, I'd
greatly appreciate the insight and help. I'm sure there's something
reasonably simple that I'm not doing, or doing out of order, but I'm a bit
stumped at the moment.

Regards,
Nick
