</blockquote><div><br></div></div><div>Aha!</div><div><br></div><div>In the latest Trunk, there's only 6 obsolete classes, as the recent Environment changes fixed the two of them. The following script, adapted from your post above, cleans them up nicely:</div>
<div><br></div><div><div>" Fix obsolete ColorTheme"</div><div>ColorTheme current class isObsolete ifTrue: [</div><div><span style="white-space:pre-wrap"> </span>ColorTheme current: nil.</div><div><span style="white-space:pre-wrap"> </span>Smalltalk garbageCollect.</div>
<div><span style="white-space:pre-wrap"> </span>ColorTheme current].</div><div><br></div><div>" Fix obsolete uncle classes (cls->meta->super)"</div><div>(Smalltalk allClasses select: [:cls | cls theMetaClass superclass isObsolete]</div>
<div>) copy do: [:withObsoleteUncle | | cls2 |</div><div><span style="white-space:pre-wrap"> </span>cls2 := withObsoleteUncle addInstVarName: 'veryUnlikelyToExisitAnywhereInTheSystemAsVariableName'.</div><div>
<span style="white-space:pre-wrap"> </span>Smalltalk garbageCollect.</div><div><span style="white-space:pre-wrap"> </span>cls2 removeInstVarName: 'veryUnlikelyToExisitAnywhereInTheSystemAsVariableName'.].</div>
<div>Smalltalk garbageCollect.</div><div>Smalltalk fixObsoleteReferences.</div></div><div><br></div><div><br></div><div><br></div><div>Running "Smalltalk shrink" then complains about two obsolete behaviours, and I this is a bug with Installer. If I just close the debugger and inspector, collect garbage and then run "SystemNavigation default obsoleteBehaviors" I get an empty array. </div>
<div><br></div><div>So it looks like the shrink works. It doesn't do much, though. My image goes from 20.9MB, down to 20.3MB. </div></div></div></div></blockquote><div><br></div><div>and (just to check) you've already done Smalltalk unloadReloadablePackages? I managed to get down to a 12 Mb minimal trunk but I had to hack fix a lot of MNUs. Basically we have work to do to make those packages really unload.</div>
