Changes in GT for supporting in Pharo 12

This page documents changes that we did in GT for supporting it in Pharo 12.

Some changes are quick fixes that fix an issue, but would be better to review.

RPackage>>#toTagName: is not in Pharo 12 so no need to patch it.

CompiledMethod>>#basicAsMCMethodDefinition basicAsMCMethodDefinition ^ MCMethodDefinition className: self methodClass instanceSide name classIsMeta: self isClassSide selector: self selector category: self protocol timeStamp: '' "self stamp" source: self sourceCode should use #protocolName instead of #protocol. Before #protocol returned a string, now it returns an object.

Added MetacelloToolBox to releaser

MetacelloToolBox Object subclass: #MetacelloToolBox instanceVariableNames: 'project methodSpec' classVariableNames: '' package: 'GToolkit-Releaser-BaselineModel-Metacello' is not much used in Pharo and was removed in https://github.com/pharo-project/pharo/pull/15287. We copied it to releaser for now. We should review how/why we need to use it.
