[JDEV] Has anyone ever actually TESTED this ?????

Tue Jan 9 21:29:47 CST 2001

Also, when trying to register a new account the same thing happens: after 
receiving the second xdb reply from my DB component jabber segfaults.

I guess something goes screwy in the xdb handling which causes any subsequent 
(the second one) xdb_get()s to crash the server.

Either way, not what anyone needs :-)

Regards,
Dennis

PS I know, I can dive into the code and find out what is wrong myself, but 
even though I have fun writing pretty much anything communicating to jabber 
through a socket, using nothing but libjabber, libxode and libpthread I do 
not know a thing about gnupth, and don't like them either :-). Besides, 
someone who was actually involved in designing the jabber architecture can 
most likely pretty much straight away determine what is wrong anyway.

Wether it is easy to fix is another question, but just knowing where the 
logic fails would be a great help.

Would some kind of a wrapper be an idea? Like a loadable module like 
xdb_file.so but one that simply re-routes the packets to an external 
component?

If so, do all xdb replies have to be returned in the right order? (ie while 
one xdb request is taking some time a later one that is already finished can 
not be returned until the first (slow) one is?
