When this happend yesterday with 13125, the only solution I found was to do a new 13215 that does not contain the code of 1817 (which we need to load with a changeset). -- Marcus DenkerÂ --Â denker(a)acm.org http://www.marcusdenker.de

some news about the consortium
by StÃ©phane Ducasse May 25, 2011

May 25, 2011

Hi pharoers yesterday we got a meeting with INRIA people and we discussed the creation of an INRIA consortium. We will follow the INRIA process and propose officially the creation. For that we will have to present a proposal by end of June so we will do it. I would like to see the consortium taking life by end of the year and there are still some work to be done there. Stef

ESUG SummerTalk - Fuel, binary object serializer
by Martin Dias May 24, 2011

May 24, 2011

Hi folks. I am really happy to announce that ESUG is sponsoring me for Fuel development through the ESUG SummerTalk. I am Martin Dias, a student at Buenos Aires, Argentina. The idea behind this SummerTalk is to implement Fuel, a binary, fast and general-purpose object graph serializer in Pharo<http://www.pharo-project.org/>. It is based on VisualWorks' Parcels ideas. Actually, the project has already started since several months. Tristan Bourgois and I started with the project while doing an internship with RMoD, INRIA <http://rmod.lille.inria.fr/web/pier>. Since a couple of months, Mariano Martinez Peck <http://marianopeck.wordpress.com/> joined the team, and now he is the official mentor in the SummerTalk. ESUG website for SummertTalk: http://www.esug.org/wiki/pier/Promotion/SummerTalk/SummerTalk2011 The website with all the necessary information is here: http://rmod.lille.inria.fr/web/pier/software/Fuel It even includes slides explaining the algorithm. In addition, a paper is in progress. For the moment, Fuel already provides the following features: - Fast pickle format. It is much faster to materialize than to serialize. - Correctly support class reshape (when the class of serialized objects has changed). - Serialize ANY kind of object. For the moment there is no object to our knowledge that we cannot serialize and materialize. - Be able to completely serialize classes and traits (not just a global name). - Support cycles and avoid duplicates in the graph. - Integration to Moose <http://www.moosetechnology.org/> with an extension to export and import their models. - Detection of globals: for example if you serialize Transcript, it is not duplicated and instead managed as a global reference. - Solve common problems like Set rehash. - Buffered writing: we use a buffered write stream for the serialization part (thanks Sven!). - No need of special support from the VM. - Try to have a good object oriented design. - Well tested (about 120 tests, for the moment). - Large set of benchmarks (even benchmarks for Moose extension). And of course, there are a lot features for the future. You can see some of them in the website and some in the issue tracker: http://code.google.com/p/fuel/issues/list We really appreciate all kind of feedback and comments. If you want to try it, check in the website how to do it. It is extremely easy. Once again, I want to thank a lot to ESUG for sponsoring the project. I plan to create a "news" section in the website with some RSS. I will keep you informed. Best regards, Martin

Pharo using old release of Announcements?
by Runar Jordahl May 24, 2011

May 24, 2011

The implementation of Announcements in Pharo 1.2.1 looks very different from the one in VisualWorks 7.7.1. For example, VisualWorks implements Object>>announce: , meaning that classes that want to âannounceâ , can simply reimplement #subscriptionRegistryOrNil , while in Pharo you need to inherit from Annoucer or reimplement all its methods. Does anyone know why there are differences between the two dialects? Is Pharo not keept up to date in this area? Kind regards Runar

MCPackage and its Metacello dependencies
by Johan Fabry May 23, 2011

May 23, 2011

Hi all, I am playing around with Monticello and Metacello and I wondered if anybody could give me some pointers as to the solution of the following question: Given a specific MCPackage that was loaded because of an unknown Metacello config, how can I obtain the list of required packages from Metacello? Thanks in advance :-) -- Johan Fabry jfabry(a)dcc.uchile.cl - http://dcc.uchile.cl/~jfabry PLEIAD Lab - Computer Science Department (DCC) - University of Chile
