hi all yesterday I decided to have a look at MC changes in squeak to see if this has an impact for the closure last fixes merge. So I did with the latest scriptLoader in the pharo repository ScriptLoader new addExtraRepositories then I select each version of the monticello package in squeak trunk starting from 314 up to 321 and used the history and asked to get the delat with the previous version. This way I could get all the changes one by one. Now I ended up having - methods refering to instance variables that were not included (methodDefinitiosn for example with 321) - when I run the tests I realized that most of the Mock classes where gone. Except for 321 I do not see a change that could affect the MC merging. Does any (lukas) use the history feature to merge? I will retry to do the changes one by one and run the tests in between to see what went wrong but I 'm not sure that what is going wrong is the changes (I have the impression that may be MC history is not capturing exactly everything but I can be wrong).
