[cxml-devel] License (?)

What exactly is the status of CXML's license? The website says it's "(L)LGPL", some files say "LLGPL", some files says "LGPL". If this isn't on purpose (but why?) maybe it would be easier to just release everything under the same license. Cheers, Edi.

[cxml-devel] cxml character handling issue?
by Adam Thorsen 14 Nov '05

14 Nov '05

I'm trying to use cl-xmpp wich uses cxml. I believe there may be an issue within cxml. The problem arises results from this call: (defvar connection (xmpp:connect :hostname "jabber.org")) This appears to be an issue only on cmucl. I'm using version 19b. Here is the backtrace: Argument Y is not a NUMBER: #\s. [Condition of type SIMPLE-TYPE-ERROR] Restarts: 0: [ABORT] Abort handling SLIME request. 1: [ABORT] Return to Top-Level. Backtrace: 0: (KERNEL:TWO-ARG-= 115 #\s) 1: (RUNES:ROD= #(115 116 114 101 97 ...) "stream") 2: (ASSOC #(115 116 114 101 97 ...) (("stream" .

[cxml-devel] READ-TOKEN-3 bad data from CL+SSL stream?

Using CVS cl-xmpp, cl+ssl and the latest cxml release I get the following error when trying to parse xml from the ssl stream: * (defparameter *c* (xmpp:connect-tls :hostname "talk.google.com" :jid-domain-part "gmail.com")) <?xml version='1.0' ?><stream:stream to='gmail.com' xmlns='jabber:client' xmlns:stream='http://etherx.jabber.org/streams' version='1.0'><?xml version="1.0" encoding="UTF-8"?version="1.0" encoding="UTF-8"><stream:stream from="gmail.com" id="8D040D109BF0BC76" version="1.0" xmlns:stream="http://etherx.jabber.org/streams" xmlns="jabber:client" UNHANDLED: #<XML-ELEMENT STREAM:STREAM (3:0:0) {B6DA4D1}> ><stream:features><starttls xmlns="urn:ietf:params:xml:ns:xmpp-tls"/><mechanisms xmlns="urn:ietf:params:xml:ns:xmpp-sasl"><mechanism>X-GOOGLE-TOKEN</mechanism></mechanisms></stream:features UNHANDLED: #<XML-ELEMENT STREAM:FEATURES (0:2:0) {B6E5979}> <starttls xmlns='urn:ietf:params:xml:ns:xmpp-tls'/>><proceed xmlns="urn:ietf:params:xml:ns:xmpp-tls"/ UNHANDLED: #<XML-ELEMENT PROCEED (0:0:0) {B6ECC41}> <?xml version='1.0' ?><stream:stream to='gmail.com' xmlns='jabber:client' xmlns:stream='http://etherx.jabber.org/streams' version='1.0'> *C* * (xmpp:auth *c* "username" "password" "clxmpp" :sasl-plain) <auth xmlns='urn:ietf:params:xml:ns:xmpp-sasl' mechanism='PLAIN'/>> debugger invoked on a SIMPLE-ERROR: Unexpected character #\Etb.

Here's the code: (setf (server-stream connection) (cl+ssl:make-ssl-client-stream (server-stream connection)) Then I proceed to write and read to the stream as if it were an (unsigned-byte 8) stream just like the original one. Is this correct? What's that Unknown character #\Etb about? I would've expected at this point to get <?xml version='1.0' ?> from the server. Any pointers would be helpful. Thanks, Erik.
