Problem with KIO::http_post

Sat Jul 14 18:44:07 BST 2007

Hi,

I'm using KIO::http_post in kdepimlibs/kblog and have a problem with my 
authenticate method in gdata_p.cpp

The unit test testgdata throws the following communication with the Google 
server on stdout:

Even if i add job->addMetaData( "connection-length", "0" ); it does not occur 
in the unit test output. I don't know how to check the traffic with 
wireshark, since it is SSL ( and this is intended by SSL ).

I hope somebody can help me.

We have got another new problem with kxmlrpcclient in kblog which also depends 
on http_post. We cannot send more than one POST in a one kio slave process. 
The second post has a content-length of 0 and therefore throws an error. 
Since both Blogger API 1.0 and MetaWeblog API in kblog depend on 
kxmlrpcclient which uses KIO::http_post in query.cpp to send the data, 
nothing works except the unit test which luckily uses a different slave for 
each connection.
If you want to try it out yourself, checkout KBlogger (the GUI to KBlog) from 
trunk/playground/pim, capture the network traffic, configure your blogging 
account and play around a bit until you get the first error box with an 
xmlrpc error.

"Antonio Aloisio" <antonio.aloisio at gmail.com> (nick GNUton) has tracked down 
the problem to the following code:

[Sa Jul 14 2007] [00:37:14] <GNUton> in the kdelibs/kioslave/http/http.cpp
[Sa Jul 14 2007] [00:37:16] <GNUton> file

[Sa Jul 14 2007] [00:38:08] <GNUton> }

I hope somebody can help here, too.

Cheers,
Christian
