Re: [Pharo-project] Behaviour>>hash is missing!

by Adrian Lienhard

IIRC Marcus introduced Behavior>>hash in 3.9 and later realized that this is not a good idea. The reason is that names of behaviors are not constant because when a class is deleted its name is changed to AnAbsolete..., which makes the name not suitable for hashing. Looking through ScriptLoader, #update10020 is where Behavior>>hash is removed again. Unfortunately the changes log is a bit unspecific as it mentions only: "changes from Reflectivity"...

Re: [Pharo-project] Trait recent change

by Adrian Lienhard

Hi Damien, Yes. I recently did a refactoring to reduce the number of traits in the kernel. That is, most of the traits are flattened down and now are only used for code reuse between the traits and the classes inheritance branches (traits count went down from 17 to 6). So if your packages change methods in traits that are now gone, you have to adapt your packages. However, all changes I did are behavior preserving.

[Pharo-project] Broken tests

by Oscar Nierstrasz

Just for phun, I ran all the tests in the Pharo image. There are only 13 failures, 2 expected failures, and no errors! I have started a page to give an overview: http://code.google.com/p/pharo/wiki/BrokenTests Please update this page with an appropriate comment if you are working on any of these (or if you fix them). - on

I think there to much different stuff at the same place : Pharo, Pharo-dev, fonts (?), SBE, ...
