Critical ClassBuilder bug

by Guillermo Polito

Hi!! I started this afternoon to see a bug on class bindings on trait methods. This one: https://pharo.fogbugz.com/f/cases/11756/Reshaping-a-class-breaks-classBindi… Now, after playing and moving around that, I noticed that the problem is worse: 1)Create Class A. 2)Create method A>>m1. 3)Create method A>>m2. 4)reshape the class (e.g. add an inst var) Then: (A>>#m2) classBinding == (A>>#m3) classBinding ==> false!!! The problem is caused because the recompilation of the methods is taking place in a class that is not yet installed in its environment (the Smalltalk system dictionary in this case). The installation of the class takes part after the reshaping+the recompilation. Then, when the methods are compiled, the binding is not available for them and new bindings are created. Would someone with more idea on the new class builder give some advice? Cause I'm a bit lost in the new class builder code :) Tx, Guille

RemoteString allInstances collect: [ :rs | rs string ] that SystemWindow>>showAbout uses the class comment. That is rather cool, if non-intuitive the first time. Makes me wonder if the System Browser <Comments> button should instead be <About>. So now it is easy - I just need to determine the replacement text. cheers, Ben

Please do not change the name :). Google "phratch" and you will see that there are only 2000 results, and many of them relate to your project. You do not want to lose that.

These plugins are included in Scratch and I reused them. I separated the source code of them in a different package. You can find them in the repository http://smalltalkhub.com/mc/JLaval/Phratch/main. The package is named PhratchPrimitiveSources.
