Caleb,
another wish to make it production ready: include a good "debug dump" function
so that users can produce reports when testing it.
We've been trying the earlier version of the real-time-editor (it's still there
actually) and had quite an amount of surprising effects; some of them may be related to
paste, but not only. I had the impression of regularly meeting a garbage state at the
server, where different clients had different views (we were speaking in Skype). The only
way I could fix the inconsistency was to restart the server. Hence the suggestion of a
stronger reporting facility so that such critical situations can be reported about and
tackled in a maturation cycle out in the wild.

Hi Caleb,
I’ve just tried and it works well! Well done this is very cool :)
Now if we want to make this production-ready we would need (IMO) at least one additional
feature which is the ability to view the list of other users editing the page and color
markers per user to show who’s adding what.
Note that I haven’t checked the code yet. Is it some prototype-quality code or is it
following the xwiki core rules and ready for being maintained?
I guess you’ve also used some hacks for lack of UI extension points (as in the lock
screen and on the edit screen where you added some extra text which I assumed you
implemented in Javascript?) which would need to be added.
Thanks

Hi all,
I'm very pleased to announce two new extensions to come out of XWikiSAS Research
and the RESILIENCE Research project.
Number One: WebSockets in XWiki!
If you're an extension developer like me, you want events, you want stuff in the
browser to be talking to stuff in the wiki and you don't want to be messing around
with Jetty and Tomcat and all different kinds of libraries and configuration every
time you need to write an application. You just want stuff that works.
Here it is:
http://extensions.xwiki.org/xwiki/bin/view/Extension/WebSocket
Include this as a dependency for your extension and the Extension Manager will
automatically include it when users install your extension. In just a few lines of
code, your users can be chatting and collaborating through the websocket and it's
based on Netty (Special thanks to the Atmosphere project for developing Nettosphere)
so it works in all versions of Tomcat and Jetty and does not need any changes to the
front-end server, just open a port on the JVM machine and you're done.
Number Two: A new Realtime Collaborative WikiText Editor.
Indeed this is not the first attempt at Realtime Collaborative editing but perhaps
it is the most academically amusing. Really this is a prototype to get a handle on
the technology before we make the leap into Realtime WYSIWYG. Whereas the previous
Realtime Collaborative WikiText editor had performance issues and was unable to
handle large pasted, the new editor uses a completely novel design which is intended
to not only port well to WYSIWYG editing but is implemented entirely on the client
with the server only relaying messages, making it portable to different web frameworks.
Check out the Realtime Collaborative WikiText Editor here:
http://extensions.xwiki.org/xwiki/bin/view/Extension/RealTime+Wiki+Editor
or install it with the Extension Manager to give it a try for yourself.
Disclamer: This is still new and might not work properly on all browsers, it certainly
will not work without websocket support.
Thanks,
Caleb
