Description Ami Setton 2007-09-29 17:50:42 UTC
Version:           2.1 (using KDE KDE 3.5.6)
Installed from:    Ubuntu Packages
OS:                Linux

If the column "IP Address" is chosen to sort, by, KTorrent sorts by treating the IP Address as a string, rather than as a numeric entity.  For example "222.x.x.x" would be seen earlier than "24.x.x.x".

I believe it should sort by IP Address numerically, not by the displayed string value.

That's the first C++ patch I've done, so be critical. How else would I learn? :)

Hey there, dvj.

Firstly, thanks a lot for addressing the issue! I'll guess you meant that the bug assignee should check the patch...but, hey, I'll in throw my $0.02, just for fun.  

1) What about just using inet_aton on both IPs and comparing the results?  There might be a lo of back-and-forth about what's more expensive, but if you lost some lines of code, it might be worth any expense (_if_ it's more expensive.)
2) Did you mean "digits" in your variable names instead of "digets" ?
Comment 4 Joris Guisson 2007-10-21 10:05:56 UTC
It would be much faster to convert the string ones and then compare with converted value, much faster.

Oops, typo : ones -> once
