Sorry, I didn't read the whole thread as I'm on vacation, but it
seems to me you are talking about the routing of unbound
namespaces - a problem we have with Gajim at the moment. When we
receive an unbound namespace, our XML parser will just fail and
there's not much we can do about that. It's nearly impossible to
fix for us, it would require changes to Python and pyxmmp, if I
looked correctly.
No, that's not the case, I stuck a patch on #3083 that seems to
almost work. It's working enough for me to be running it anyway.
The trick in this instance was to tell the XML parser not to bother
handling xml namespaces, and do it ourselves, giving considerably
more flexibility. I'd be willing to bet that in most cases, it'd be
easier - Gajim's a bad case because xmpppy itself has rather bizarre
handling of namespaces to begin with.
OTOH, it's easy to not route unbound namespaces.
Not true. It's a substantial performance impact for us, and
worthwhile avoiding in many instances.
There is already a patch for ejabberd that does this. The
performance loss introduced by it is so minimal that you can
ignore it.
That's largely because ejabberd already dopes much deeper parsing
than for example we do. And in any case, this does not mean that
Gajim doesn't have to bother solving its own issues.
There is a ticket for that bug, which I unfortunately don't have
handy atm. And I can't look it up as I'm writing the message
offline.
