Yes, I looked at it and I gave detailed feedback in my previous mails. No, I won't include it for the reasons given in my previous mails.

The solution I proposed was a new publishing interface for MC that works with the 1-1 mapping between RPackage and PackageInfo. Like this, for saving we would be force to save the new package. So, in your case, when you would open the NewMC, you would see in the list: Foo Foo-Zork Foo-Cat* The +Package button would disappear altogether. You would be provided with the possible things to commit, and then you would not have to think about the mapping at all. All you have to do is select each of the RPackages that you want to commit, and if there does not exist a correspondent Monticello package for it, you would be asked to provide the repo and then the creation would happen transparently. > So we could always load and create a RPackage for each Category. This would be simpler. In your solution, you would again split the mapping logic of load from that of publishing but you would change the loading mapping such that when you load you create only one category per PI. Perhaps that is indeed simpler, but you would lose the extra info of categories. Were my explanations clearer now?

Re: [Pharo-project] allOverriddenMethods is confusing

by StÃ©phane Ducasse

So allOverriddenMethods returns all the methods of the complete system and it may be correct but strange to have it on the instance side. Now my hypothesis is that > overriddenMethodsDo: aBlock "Enumerates the methods the receiver contains which have been overridden by other packages" ^ self allOverriddenMethodsDo: [:ea | (self isOverrideOfYourMethod: ea) ifTrue: [aBlock value: ea]] check the complete system for every package snapshot and since we have a lot of override because of polymorph we pay the price. I will fold the overrides first and try to understand mc Stef
