Position for a PhD student on Hot software update
by Noury Bouraqadi Sept. 23, 2015

Sept. 23, 2015

Hi, As part of the ongoing partnership between INRIA and Mines Douai, we have a funding for a PhD student to work on hot software update. You'll find below a description of the position. Best, Noury â Prof. Noury Bouraqadi Ecole des Mines de Douai http://car.mines-douai.fr/noury --- CONTACT Prof. S. Ducasse, stephane.ducasse AT inria.fr, INRIA, France Prof. N. Bouraqadi, noury.bouraqadi AT mines-douai.fr, Mines Douai, France Dr. M. Denker, marcus.denker AT inria.fr, INRIA, France Dr. L. Fabresse, luc.fabresse AT mines-douai.fr, Mines Douai, France CONTEXT Building next generation systems that can not be stopped is an interesting challenge for industry. Indded, when we need to replace current software for an upgrade or a bug fix, it is mandatory to stop the old running version, make the change and then restart the new version. However, there are situations where a such process is either impossible or at least undesirable because of the costs resulting from a shutdown (e.g production line, robot on mars, ...). We believe that software built with from the beginning the property to work indefinetly, will be by construction more robust to change, intrinsicly capable of evolution and more agile than traditional software. Dynamic languages such as CLOS, Ruby, Python, and Pharo provide a support for updates that only involve code change. Even if they are more advanced compared to other languages, their solutions ar mainly ad hoc and deserve being rethought. We believe it is important to have a mechanism and an infrastructure that allow adaptive and safe software updates. By "safe" we mean that this solution should support different conditions, such as a series of updates performed in the wrong sequence. In such situations, instances of changed classes should migrate in a satisfactory fashion. Safety also means verifying loaded changes. This means that changes should be checked and possibly rejected if they make the system instable or if they introduce errors. SCINTIFIC GOALS The questions we would like to target in this PhD are the following: - What is a good inftrastructure to support a dynamic and reliable code update? Do we need to analyse changes? - Does an infrastructure based on isolated environments is enough to ensure update safety? What atomicity level is required? - Which meta-object protocol is required to migrate objets? - Would it be interesting to have different version of a given class or package for the same software?

Help with RBTransformationRule needed!
by Yuriy Tymchuk Sept. 22, 2015

Sept. 22, 2015

Hi everyone, I need someone who knows how RBParseTreeRewriter & co. work. May of quality rules are implemented as rewrite rules which is cool. But they donât report the interval in source code which can be highlighted to help with understanding of the issue. Nowâ¦ the check happens in RBTransformationRule>>#checkMethod:. Is it possible to obtain the matched string there? Because in that case we can get highlighting working which will be very useful. Cheers! Uko

TextAttributes in source code or class comment?
by Martin Dias Sept. 22, 2015

Sept. 22, 2015

Hi all, The source code of a method could be a Text, with TextAttributes. In such case, it will be written down to a stream with a "]style[" suffix. Through a special parsing, the system can reconstruct the original Text. I think the use of Text in source code or class comments is discouraged, but I understand we kept support for some backward compatibility. Now, may be it's time to remove this feature. With Pablo, we looked for uses of ]style[ in the .sources and .changes files of a new Pharo 5.0, and there are no real uses. It appears in some comments only, as examples. We tried to find past discussions about this feature, because we're sure there were, but we couldn't. So, the questions is: Can we remove support for text in source code or class comments in Pharo 5.0? I think I can propose a slice. Regards, MartÃn PS: I was trying to cut dependencies of Text-Core with System-Changes and System-Changes.
