Re: kopete (KDE 4.3.0) and Yahoo (fixed)

[Sverre Froyen <sverre%viewmark.com@localhost>]

Hi,

It appears that not many use kopete with Yahoo, but for those who do and have 
connection problems, the following patch (to kdelibs4) may help.

The connection failure that I am seeing happens because the Yahoo connection 
socket has its mode set to read-only.  Kopete is therefore unable to send any 
data to Yahoo. 

Analysis:

When the socket is set up (by KBufferedSocket), the default mode is read-only.  
Later the method "connect" is called with the hostname and port.  At this 
point, the KBufferedSocket instance is changed to read-write but the internal 
socket device (returned by the socketDevice() call) is still read-only.  The 
reason for that is that the call to KSocketDevice::connect follows the path

if (kde_connect(m_sockfd, address.address(), address.length()) == -1)
     {
       if (errno == EISCONN)
         return true;  <--- we end up here!!!

bypassing the open call (at the bottom of the function) that sets the mode to 
read-write.

The patch corrects this.

Regards,
Sverre
