I want to move the latest vm to stable... I need feedback !

by Esteban Lorenzano

Hi guys, I want to move latest vm to stable (for Pharo 6.0, of course). And I have the idea there are still some blocking issuesâ¦ can you I have this issues in mind: No write right on Windows with the new VM <https://pharo.fogbugz.com/f/cases/19525/No-write-right-on-Windows-with-the-…> Freetype2 primitive failed [error 2][unknown file format] <https://pharo.fogbugz.com/f/cases/19315/Freetype2-primitive-failed-error-2-…> -> for this Iâm testing the solution pointed here: http://log.smallworks.eu/web/post/289 <http://log.smallworks.eu/web/post/289>, plus a fix Phil sent me. Image freezes on Linux if it was previously saved on Windows <https://pharo.fogbugz.com/f/cases/19272/Image-freezes-on-Linux-if-it-was-pr…> â¦ but also anything else that I might be missing. cheers, Esteban

Re: [Pharo-dev] Collections and Kernel

by Guillermo Polito

Hi, First, I'll make a not that is implicit in the conversation: the loading/deployment granularity in Pharo is the package, not the class. And as such, a dependency to a class will require the entire package, because we cannot load half a package. Okok, "yes, we can", but this is not the default behaviour of the system when we work with our current tools (monticello, metacello, iceberg, the dependency analyzer...). Now to extend a bit more on the answers already given: 1 - We already discussed about doing a split like that. Maybe not Kernel-Collections, but Collections-Kernel. Nowadays the collections package is not modularised in terms of usage, but in terms of implementation (ordered, unordered...). And here we see where the "meaningfulness" of a package/package name clashes with its deployment, because of a big deployment granularity. 2 - YES. I want to split all the time related stuff from the kernel. And make them System-Time or whatever. The other thing is that little tasks like these "clean this package", "split this other one", "fix the dependencies of this one" we have hundreds. And we chose the ones that will provide more impact in the short term with the little time we have to work on them... Clement, I think you should be able to use the dependency analyser to extract the exact list of classes your package depends on, and then validate that in a lint rule. Check with Christophe, he is the dependency analyser master.

Hi, I would like to help in cleaning, composing and enhancing the ideas page. I already see some old projects whose mentors either left the community or may not be 100% available for mentoring (like Camille Teruel). We should clean that page. Besides, I'm interested in knowing the official reasons for why we were rejected last years :P.

Right now, it considers the author is just the current Author. That is a good idea. It is what I would expect. Now I wonder if its possible to record both, with the original author's modification date as well as date loaded into the Image. It could perhaps be displayed as " Me(OriginalAuthor) LoadedDate(OriginalDate)" ??
