Re: [Pharo-dev] Nautilus memory leak/hog crashing Pharo
by Goubier Thierry June 30, 2014

I'm trying to see if I could do it in a cleaner way, and I found it! On partial updates, AltBrowser is able to cleanly delete the node morphs because it sends #noteRemovalOfAll: aCollection to MorphTreeMorph, which has the selection testing and removal code. Which means changing MorphTreeMorph>>updateContentsWithPreviouslyExpanded: aNodeList nodeList := nil. self noteRemovalOfAll: self allNodeMorphs. "<-- Changed" (self nodeList isNil or: [ self nodeList isEmpty ]) ifTrue: [ nodeList := nil. ^ self emptySelection ]. self addSubmorphsFromNodeList: self currentNodelist previouslyExpanded: aNodeList It solves the problem. However, I don't like this that much overall, because delete is never sent to the node morphs themselves, and this seems very wrong to me.

That is like saying you can install Pharo by double-clicking a Pharo image. That misses a few steps. And there are several ways to install prerequisites, some of which don't work at all, others cannot be upgraded. Stephan
