[Pharo-project] plan for 1.1

May 27, 2010

Interesting, in an 11371 AND the new 11373 core image this works: --------------------------------------------------------------------- Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfNile'; load. ((Smalltalk at: #ConfigurationOfNile) project version: '1.1') load --------------------------------------------------------------------- but this --------------------------------------------------------------------- Gofer new squeaksource: 'MetaSource'; package: 'ConfigurationOfMetaSource'; load. (Smalltalk at: #ConfigurationOfMetaSource) load --------------------------------------------------------------------- => which indirectly loads ConfigurationOfPharo => which indirectly uses 1.1 of ConfigurationOfNile => which crashes while loading Nile with the stack below. If you use older 11367 core image it works without any problem. Bye T.

I move the gettext package there, as it is the right place for long term support for this package. Please, from now, commit any change there. http://www.squeaksource.com/PharoNonCorePackages Hilaire

Using ConfigurationOfPharo anyone is able to rebuild an own beta to test and from time to time mariano can upload a full beta image. Bye T. -- GRATIS fÃ¼r alle GMX-Mitglieder: Die maxdome Movie-FLAT!

Open a system browser 2. Select a class that has tests. Example ArrayLiteralTest. 3. Select any test method, like testByteArrayBase. 4. Right button, "debug test" 5. When the debugger raise, just click on Proceed There you will get a BlockCannotReturn: Block Cannot Return I attach PharoDebug.log in the issue tracker.

[Pharo-project] Towards clean unloading Morphic (an idea)
by Igor Stasenko May 27, 2010

May 27, 2010

Hello, i just thought, that in order to get down to a minimal kernel image, it would be nice to move all Morphic globals into a shared pool. Things like, World, ActiveWorld could be placed into a MorphicPool class. Then we can make an easy transition 1. add this pool to classes which using that global & recompile them 2. for classes, which should have no dependency from Morphic, use a messages like Object >> currentWorld ^ (Smalltalk at: #MorphicPool ifAbsent: [ self error: 'bummer' ]) currentWorld . Then, i hope, you can unload the Morphic using MC and it will leave no trace in an image (or at least less trace than usual ;). Same could be applied to Graphics package (to get rid a Display global) -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] #and:and:and: deprecated on 1.1, why?
by nullPointer May 27, 2010

May 27, 2010

that methods is marked like "deprecated": 'Use self deprecated: 'Use and: instead'. ' But curiosly the method #and:and:and:and: appears normal, without deprecation. That behavior is correct?

Hi guys we were discussing how we can handle 1.1 and the flux of good changes. Here is the proposal: we take two or three weeks to let people try their code in 1.1 beta we integrate fixes that are important or easy then we wait one week then we launch 1.1 rc and 1.2 unstable does this plan look ok for you? The key point is that we want to avoid to have a pile of changes pending because they can rot easily. Stef

[Pharo-project] ReferenceStream, tree or graph?
by Mariano Martinez Peck May 26, 2010

May 26, 2010

Hi folks. I have a question. Reading http://wiki.squeak.org/squeak/2318 it says: "This is a way of serializing a tree of objects into disk file. A ReferenceStream can store one or more objects in a persistent form, including sharing and cycles." I am confused. If it has cycles, shouldn't it be a graph instead of a tree? I know this is subtle, but it is important for me. I want to know if ReferenceStream supports a graph of objects, NOT only a tree. Does someone know? Thanks Mariano
