           Summary: Too long messages don't get split correctly
           Product: konversation
           Version: unspecified
          Platform: Slackware Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: konversation-devel kde org
        ReportedBy: wiedi elbone net


Version:           0.19+ #3119 svn (using KDE KDE 3.5.3)
Installed from:    Slackware Packages
Compiler:          gcc 3.4.6 
OS:                Linux

If a very long message is sent to a channel it gets split up - but a part in the middle of the message is left out, for example if i send a message like "AAAAAAAAAABBBBBBBBBBCCCCCCCCCCDDDDDDDDDDEEEEEEEEEEFFFFFFFFFFGGGGGGGGGGHHHHHHHHHHIIIIIIIIIIJJJJJJJJJJKKKKKKKKKKLLLLLLLLLLMMMMMMMMMMNNNNNNNNNNOOOOOOOOOOPPPPPPPPPPQQQQQQQQQQRRRRRRRRRRSSSSSSSSSSTTTTTTTTTTUUUUUUUUUUVVVVVVVVVVWWWWWWWWWWXXXXXXXXXXYYYYYYYYYYZZZZZZZZZZ[[[[[[[[[[\\\\\\\\\\]]]]]]]]]]^^^^^^^^^^__________``````````aaaaaaaaaabbbbbbbbbbccccccccccddddddddddeeeeeeeeeeffffffffffgggggggggghhhhhhhhhhiiiiiiiiiijjjjjjjjjjkkkkkkkkkkllllllllllmmmmmmmmmmnnnnnnnnnnooooooooooppppppppppqqqqqqqqqqrrrrrrrrrrssssssssssttttttttttuuuuuuuuuuvvvvvvvvvvwwwwwwwwwwxxxxxxxxxxyyyyyyyyyyzzzzzzzzzz{{{{{{{{{{||||||||||}}}}}}}}}}~~~~~~~~~~"
konvi shows in the rawlog (outgoing):

[23:03:20] << PRIVMSG #/dev/brain :AAAAAAAAAABBBBBBBBBBCCCCCCCCCCDDDDDDDDDDEEEEEEEEEEFFFFFFFFFFGGGGGGGGGGHHHHHHHHHHIIIIIIIIIIJJJJJJJJJJKKKKKKKKKKLLLLLLLLLLMMMMMMMMMMNNNNNNNNNNOOOOOOOOOOPPPPPPPPPPQQQQQQQQQQRRRRRRRRRRSSSSSSSSSSTTTTTTTTTTUUUUUUUUUUVVVVVVVVVVWWWWWWWWWWXXXXXXXXXXYYYYYYYYYYZZZZZZZZZZ[[[[[[[[[[\\\\\\\\\\]]]]]]]]]]^^^^^^^^^^__________``````````aaaaaaaaaabbbbbbbbbbccccccccccddddddddddeeeeeeeeeeffffffffffgggggggggghhhhhhhhhhiiiiiiiiiijjjjjjjjjjkkkkkkkkkkllllllllllmmmmmmmmmmnnnnnnnnnnooooooooooppppppppppqqqqqqqPRIVMSG #/dev/brain :qqqrrrrrrrrrrssssssssssttttttttttuuuuuuuuuuvvvvvvvvvvwwwwwwwwwwxxxxxxxxxxyyyyyyyyyyzzzzzzzzzz{{{{{{{{{{||||||||||}}}}}}}}}}~~~~~~~~~~

the other user then recives an incorrect version:

[23:03:20] >> :Wiedi!wiedi p549C4E18 dip t-dialin net PRIVMSG #/dev/brain :AAAAAAAAAABBBBBBBBBBCCCCCCCCCCDDDDDDDDDDEEEEEEEEEEFFFFFFFFFFGGGGGGGGGGHHHHHHHHHHIIIIIIIIIIJJJJJJJJJJKKKKKKKKKKLLLLLLLLLLMMMMMMMMMMNNNNNNNNNNOOOOOOOOOOPPPPPPPPPPQQQQQQQQQQRRRRRRRRRRSSSSSSSSSSTTTTTTTTTTUUUUUUUUUUVVVVVVVVVVWWWWWWWWWWXXXXXXXXXXYYYYYYYYYYZZZZZZZZZZ[[[[[[[[[[\\\\\\\\\\]]]]]]]]]]^^^^^^^^^^__________``````````aaaaaaaaaabbbbbbbbbbccccccccccddddddddddeeeeeeeeeeffffffffffgggggggggghhhhhhhhhhiiiiiiiiiijjjjjjjjjjkkkkkkkkkkllllllllllmmmmmmmm 
[23:03:20] >> :Wiedi!wiedi p549C4E18 dip t-dialin net PRIVMSG #/dev/brain :qqqrrrrrrrrrrssssssssssttttttttttuuuuuuuuuuvvvvvvvvvvwwwwwwwwwwxxxxxxxxxxyyyyyyyyyyzzzzzzzzzz{{{{{{{{{{||||||||||}}}}}}}}}}~~~~~~~~~~ 

as you can see something got lost.
I think this is because a message (including protocol) on irc can't be more than 512 chars. Konvi does not violate this rule by splitting exactly at the point so that the outgoing message is 512 chars long.
But the receiving message is longer (as it includes more protocol overhead) and so the ircd cuts off the last part.

X-Chat cuts this message at 447 chars, together with protocol 468 chars.

So it is received correctly.

I did not test if this is just a magic number or if it gets calculated from the own hostmask + channel length.

If you need some more information feel free to mail me ;-)
