Opal problem causing crash but old compiler works [WAS] Re: [Vm-dev] Debugging VM crash, INVALID RECEIVER / a(n) bad class ??
by Mariano Martinez Peck Nov. 23, 2015

Nov. 23, 2015

Hi guys, So I found out the exact method that is causing the VM crash. If I compile the method with Opal, it crashes the VM when I execute the code that use that method. If I compile it with old compiler, the code does work correctly. I tried comparing both compiled methods compiled from both Compilers and I cannot see real differences. They both seem to have similar (same?) bytecodes, literals, decompiled string, etc. The only difference I see is in #frameSize (old compiler one is 16 while Opal one is 56). Any idea what else can I check/compare? I also tried in Pharo 5.0 but same results.

Jenkins job @ ci.inria.fr
by Lucas Godoy Nov. 23, 2015

Nov. 23, 2015

Hi everyone I have two jobs in ci.inria.fr for the project Tracks. One is for Pharo 3.0 and another for Pharo 4.0. Since Tracks requires Epicea to run and Epicea is no longer mantained for Pharo 3.0, the Tracks job for Pharo 3.0 is failing and it doesn't make sense to keep it. I only want to keep the job for Pharo 4.0. This is the URL of the job: <http://goog_1488548907> https://ci.inria.fr/pharo-contribution/job/Tracks/PHARO=30,VERSION=developm… I haven't logged-in in Jenkins in quite a while and now my authentication fails. I may have just forgotten my password or my credentials are expired. Can somebody at INRIA delete the Tracks job for Pharo 3.0 or reset my password so I can delete it, please? Thanks in advance! -- ------------------------------------------ Lucas Godoy ------------------------------------------

Refactoring and traitsâ¦
by Yuriy Tymchuk Nov. 23, 2015

Nov. 23, 2015

Hi guys, is it a known issue that if you are refactoring something (eg. doing a class rename) and some changes should happen in a method which comes from trait, then new methods are compiled in concrete classes instead of changing the trait method? Cheers. Uko

A plea for responsive coding
by Thierry Goubier Nov. 22, 2015

Nov. 22, 2015

Hi all, I would like to ask you, all of you, something significant when doing GUI coding: Pay attention to performance! With the current state of our technology (Morphic, Bloc, whatever comes next) your target should be one hundred milliseconds (100 ms), for opening / redisplaying the widget. Why? - Because, in 10ms, Morphic can open and layout dozens of Morphs on a low-end machine (1.4GHz Celeron). - Because most of you work on 3GHz+ i7 Macbook Pro (so, at 10x the cpu performance of that said Celeron). - Because you are not to reproduce the past: that your current tools are slow is no excuse. - Because you now have well designed core widgets (FT) that behaves in O(1) and opens fully loaded in 10's of milliseconds So, profile and clean your code! Eliminate unneeded caches! Clean your architectures! Avoid or mark slow code and bottlenecks! And bring numbers when you want to criticize the performance of a subsystem... Thierry
