Hello Duncan and others,

We, the developers of Wt, are a bit surprised to see your efforts on
integrating Wt with Yast causes crashes and other problems (we
followed your progress on the yast mailing list and the comments on
your blog). Normally, Wt runs uber-stable (e.g. on our public site)
and we want to keep it that way, so we're very eager to know what
exactly caused the crashes so that we can catch and fix the bugs. We
picked up something about Wt's thread model being incompatible with
Yasts use of threads. Therefore, we have patched Wt so that you can
disable all use of threads completely (in our CVS version).
Could you provide us with some insights about your architecture and
how you integrate Wt? We may be able to help you out so that Wt and
Yast become good friends (e.g. by implementing something similar to

For me QSocketNotifier was the missing part, as Qt offers a way to react to
a socket event while still integrating the event loop.

Also, is there a way in Witty to get into and out of the event loop?

Anyway, in case of getting further, we still faced some basic design
problems, like the UI having to run as root, unless we used fcgi, for which
there too many missing pieces in YaST (authentication?)

I've done a quick experiment with fcgi setup. It did not work, I do not have
enough knowledge about fcgi to figure out why. Wt connector waited for the
session endlessly.
