[Pharo-project] Funky BalloonMorph

by Hilaire Fernandes

The balloon morph color and layout mess really give a bad bad feeling, I gave a look to try to fix it: * COLOR, it seems to be just an initialize issue, one should execute this in the image: BalloonMorph setBalloonColorTo: BalloonMorph defaultBalloonColor. * FONT, same problem, one should execute in the image : BalloonMorph balloonFont: StandardFonts defaultFont. * LAYOUT, the problem comes from the method String>>withNoLineLongerThan: doing very badly its job. Moreover this method need to be refactored to be readable, it is too looooong. Jannick can you give a try, you seem to be the author? Hilaire

Here is what I suggest. - Keep a log of these fixes may be on the cog vm - did you publish your fixes using the git infrastructure we put in place - because without it we will not work. - Write some tests - Soon igor will resume his work on vm building with hudson and we should get some regression testing tests. - Soon we should be able to introduce these changes and evaluate their impact. - we should push the git infrastructure.

I also have my modest bitShift: improvments pending (http://bugs.squeak.org/view.php?id=7109) Maybe I haven't performed enough tests to assert the performance gain. The changes are reliable, I run a VM with both improvments without crash for months. I could try to further improve the exponentiation algorithm by mixing a sliding window exponentiation with Montgomery multiplication. There would be other optimisations possible : each modular product fits on a given number of bytes so we could recycle allocated LargeInteger for storing intermediate results rather than letting vm do it.
