Raul, thanks for the patch. We appreciate contributions such as these, particularly ones that work on improving what exists .. and this bit of code definitely could use it. However, we do not interact with each other in the way you did in your comment here. We try to show each other respect and understanding. Not only do we find more enjoyment and team spirit this way, but it prevents people from treating us the same way. There are issues with your patch which I cover in my review, but I don't suggest you ought to learn how to write better code or otherwise insult you. What would that achieve, besides getting on your nerves? Nothing. You did not answer Aleix's question about how you measured the improvement, which is a very valid question. The least one can do is respect an honest question with an honest answer, yes? Our code of conduct describes our commitments to each other in these things: http://www.kde.org/code-of-conduct/ I hope you can receive this comment in the constructive manner which I intend it, and look forward to more of your patches in the future. :) - Aaron J. ----------------------------------------------------------- This is an automatically generated e-mail.
