ExternalSemaphoreTable curious garbageCollect
by Ben Coman Sept. 22, 2016

Sept. 22, 2016

A curiosity I can't work out and maybe I can learn something... ExternalSemaphoreTable unprotectedExternalObjects class ==> Array so in #freedSlotsIn:ratherThanIncreaseSizeTo: how does the garbageCollect manage to free slots given that the Array holds strongly to its elements? cheers -ben

PrimitiveFailed: primitive #elementsForwardIdentityTo: in Array failed
by HernÃ¡n Morales Durand Sept. 21, 2016

Sept. 21, 2016

Hi I don't know if this was reported. Apparently there is a problem when migrating a large number of instances, I have aprox. 270,000 instances from which I simply pulled up an ivar in their class to a higher superclass, and a PrimitiveFailed raised. It can be reproduced by installing Territorial in Pharo 5.0 with Spur VM 5.0 from 4 May 2016 in Windows 8.1 (this is the standard image installed using wget command line in msys). Gofer it smalltalkhubUser: 'hernan' project: 'Territorial'; configuration; loadDevelopment. TCityOrganization addOpenGeoCode Then manually install Territorial-HernanMoralesDurand.163 from Monticello. Backwards (installing .163, populating, then .166) also reproduces the issue. Is there a fix for this? --- The full stack --- Array(Object)>>primitiveFailed: Array(Object)>>primitiveFailed Array>>elementsForwardIdentityTo: TerritorialCity class(ClassDescription)>>updateInstances:from:isMeta: TerritorialCity class(ClassDescription)>>updateInstancesFrom: PharoClassInstaller>>updateClass:to: [ 1 to: old size do: [ :index | self updateClass: (old at: index) to: (new at: index) ]. old elementsForwardIdentityTo: new.

SharedPool method definitions do not resolve Class names
by Ben Coman Sept. 21, 2016

Sept. 21, 2016

This is probably my lack of understanding but I found this surprising behaviour.... I was trying to add a method to a subclass of FFIExternalEnumeration and it was not recognising classes. I traced this back to SharedPool which can be demostrated by trying to save the following method... SharedPool >> test1 ^Object reports... "Unknown variable: Object please correct, or cancel:" Any insights? cheers -ben

Version dependent Metacello Platform
by Torsten Bergmann Sept. 21, 2016

Sept. 21, 2016

Hi, the expression MetacelloPlatform current defaultRepositoryDescription returns the meta repo for pharo 3 ('http://smalltalkhub.com/mc/Pharo/MetaRepoForPharo30/main') even when run in Pharo 6. This is because MetacelloPharoCommonPlatform has a single subclass "MetacelloPharo30Platform". I guess this is because Metacello scripting API was integrated back in Pharo 3. Do we need to update this to a MetacelloPharo60Platform in Pharo 6 ? Thx T.
