Re: [Pharo-dev] Can we rollback the MC changes?

by Thierry Goubier

Hi Stef, this is probably the lazy ancestor thing, but, as long as nobody looks seriously into why this happens, then we can't be sure (I just suspect it is a side effect of that). To remove it, it's easy: remove MCLazyVersionInfo. revert the effect of MCLazyVersionInfo>>install.

If you want to see how deep it is broken take Latest update: #50063 open rubric repo merge alain 206 and see that we lost all the feedback on merged ancestor. So to merge now I will click on all the files to make sure. Great!

Can we rollback the MC changes?

by stepharo

Hi I strongly encourage that we rollback the change in MC that broke the ancestry. This enhancement really breaks MC and makes quite difficult to work with it. How should we proceed? Stef PS: do not tell me that this is working.
