While updating pharo 1.2, after an EndOfCentralDirectory error, I got
a very unresponsive image...
((WeakArray classPool at: #FinalizationDependents) as: Array)
select: [ :each | each notNil ]
thenCollect: [ :each | each class -> each size]
->
{(WeakIdentityKeyDictionary->22370). (WeakRegistry->0).
(WeakRegistry->0). (WeakRegistry->0). (WeakRegistry->2)}
I tried to inspect it 5 minutes ago, but hey, answer in another email...
Ah, OK, cmd+shift+. just worked. I had to interrupt
#finalizationProcess itself finally...
Oh inspect is sorting the keys... unusable.
So what's in the array ? Things like
(ScriptLoader>>#update12125 "a CompiledMethod(0)")->a
MCMethodDefinition(ScriptLoader>>update12125)
(PragmaCollector>>#release "a CompiledMethod(964689920)")->a
MCMethodDefinition(PragmaCollector>>release)
(Float>>#arcSin "a CompiledMethod(358088704)")->a
MCMethodDefinition(Float>>arcSin)
I don't understand yet, but I begin to gather clues why updating pharo
goes so badly...
