Re: [Pharo-users] Pharo 4.0 -- Inspecting a recursive data structure is slow

by Andrei Chis

Hi Hannes, Can open a bug report? I though most recursive problems were fixed in the new inspector. Seems that there are still some related to printing recursive structures. You can switch to the previous inspector (GTInspector setGTInspectorEnabledStatus: false), however, this bug seem to also kill that inspector. Cheers, Andrei On Sat, Aug 29, 2015 at 7:16 AM, H.

Pharo 4.0 -- Inspecting a recursive data structure is slow

by H. Hirzel

Hello I have realized that inspecting a recursive data structure is very slow in Pharo 4.0 A test case: | myDict | myDict := Dictionary new. myDict at: #hello put: 'hello'. myDict at: #recurHello put: myDict. myDict inspect It takes a long time for the inspector to come up. And the image freezes later on if you continue. The problem is with the inspector because if I do | myDict | myDict := Dictionary new. myDict at: #hello put: 'hello'. myDict at: #recurHello put: myDict. 3 + 4 inspect it comes up instantly. As a comparison I attach the Cuis ** test result. The inspector comes up instantly and the image does not have any problems. What are the workarounds in Pharo 4.0? - Setting a time out somewhere? - Disabling certain functions? - Loading a simpler inspector? Regards Hannes ** current build 2463.image https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev

Re: [Pharo-users] Becoming good at VM development

by Christian Caldeiro

Hi Ichiro, there are a bunch of posts in Mariano Martinez Peck's blog named "journey through the VM", done some years ago. He writes about anything related to the VM, how to build it, class format, bytecodes, detailed description of the CompiledMethod class, etc. You can find the first post here: https://marianopeck.wordpress.com/2011/03/31/journey-through-the-vm/ Definitely worth reading!

STON is the way to go to save preferences. But I do not have free cycles.

I've already read those blogs. There are lots of useful information - it seems - but what I want is a head start, something that starts from zero but for someone who has programming knowledge. I will definitely read the blue book. That goes first! Any more sources, indications?

Preferences does not exist as a class. You could use STON. > On 28 Aug 2015, at 10:31, H. Hirzel <hannes.hirzel(a)gmail.com> wrote: > > P.S.
