Re: [Esug-list] Worrying issue re compilation in Pharo 1.4

by Graham McLeod

Hi Marcus, Your answer is as I suspected. The suggestion to add an instance variable, forcing a recompile, from Andrew P Black, seems to resolve the problem.. There still remains the question of how the system allowed the situation to arise in the first place tho.. Thanks for the help.

The decompiled code and the bytecode are in sync: 14 <62> popIntoRcvr: 2 is storing into the properties instance variable, and the decompiled code shows it correctly. But the bytecode should have been regenerated and do 14 <62> popIntoRcvr: 3 So the bug is definitly related to not recompiling the methods after the shape of the class was changed.

Worrying issue re compilation in Pharo 1.4

by Graham McLeod

Hi Guys I am trying to use Pharo1.4 Latest update: #14438 as downloaded in the Moose 4.7 image. I am loving most of the changes and system tools - well done all! But I am coming up with a worrying bug where there is a difference between Source code and decompiled source code. Specifically, this occurs with two set methods which point to the wrong instance variable slot. So, when the code runs, the wrong variables are updated. Here is an example: Class definition: Thing subclass: #Relationship instanceVariableNames: 'context fromNode properties relType toNode' classVariableNames: '' poolDictionaries: '' category: 'Sapiento' Source Code: relType: anObject relType := anObject Byte Codes: 13 <10> pushTemp: 0 14 <62> popIntoRcvr: 2 15 <78> returnSelf Decompiled Code: relType: anObject properties := anObject NOTE: properties is updated instead of relType. I may have added a new instance variable since the original class definition. Are there known issues / available fixes around this? Please advise Thanks in advance. Graham

Hi, Just a quick report of yesterday meetup. We planned to make a Demo meetup. It ended up in a VA Smalltalk presentation by Sebastian Heidbrink (thanks Sebastian!). He went through the creation of a small application from scratch (how to load stuff, ENVY's basics, etc). Pretty interesting for those of us who haven't seen anything else that screenshots on Instantiations website! Seven people showed up (two of them were new to Smalltalk). Nothing is decided yet for next time but we will try to keep the monthly meeting. Once again, if you're in Vancouver area, you can join the meetup group: http://www.meetup.com/Vancouver-Smalltalk-Developers-Group/ Cheers, Francois -- http://tulipemoutarde.be CA: +1 778 558 3225 BE: +32 65 709 131 On 08/06/12 12:46, Francois Stephany wrote: > Hi, > > The next meetup of the Vancouver Smalltalk Developers Group is scheduled > for next thursday in Gastown. > > This will be a demo meetup.

ESUG revenue comes only from sponsoring, donations, and registrations to the ESUG yearly event (for 20 years!).
