debugger feature I would pay for
by stepharong March 13, 2017

March 13, 2017

Hi doru You have some features and I would love to use it for real. Here is my scenario: I have a test failing in pillar dev but not in my previous image. :( I want to run a test in an image (green test). - get the test execution stack In another image (dev), I would like to load the green test stack and say to the debugger - execute the test in the local image up to there is a change by comparison with the other. I would pay for this feature. Stef

Growing large images: the case of Moose models
by ClÃ©ment Bera March 12, 2017

March 12, 2017

Hello everyone, This morning I investigated with Vincent Blondeau a problem reported by the Moose community a while ago: loading Moose model is slower in Spur (Pharo 5+) than in pre-Spur (Pharo 4 and older). In general, this problem was present for anyone growing images to a significant size. To investigate the problem, we loaded a 200Mb[3] Moose model on a 250Mb image, growing the image to 450Mb. Loading such a model takes 2 minutes in Spur and 1m30s in pre-Spur VMs. Using the stable Pharo VM, the analysis results were the following: - total time spent to load the Model: 2 minutes - time spent in full GC: 1 minute (4 fullGCs) - time spent in scavenges[1]: 15 seconds On the 2 minutes spent, we have 50% of the time spent in full GCs, 12.5% in scavenges, 37.5% executing code. We then used the latest VM that features the new compactor (VM from beginning of March 2017 and over). The full GC execution time went down from 1 minute to 2 seconds. In addition, we increased the size of Eden[2] from 4Mb to 12Mb. Time spent in scavenges decreased from 15 seconds to 5 seconds. Overall, loading the model is now taking ~50 seconds instead of 2 minutes. To increase Eden size, one needs to run a script similar to: | currentEdenSize desiredEdenSize | currentEdenSize := Smalltalk vm parameterAt: 44. desiredEdenSize := currentEdenSize * 4. Smalltalk vm parameterAt: 45 put: desiredEdenSize. *And then restart the image.* I hope this report can be useful for some of you. I will try to make a blog post out of it, detailing other GC settings one can change from the image to improve performance. Best, Clement [1] A scavenge is basically the garbage collection of only young objects [2] Eden is basically the space where objects are initially allocated. [3] All numbers in the report are order of magnitudes and not precise numbers

perform:withArguments: and collection
by Peter Uhnak March 12, 2017

March 12, 2017

Hi, Apparently sending #perform:withArguments: and using OrderedCollection leads to PrimitiveFailed. I can recast it, but maybe we can just add (argArray isArray) ifFalse: [ ^ self error: 'Arguments must be instance of Array' ] to make the error less cryptic. (or allow OrderedCollection, but since the operation is done in VM it might be needlessly more work.) Peter

Did we lose edit-in-place in GT Inspector in Pharo 6?
by Sean P. DeNigris March 12, 2017

March 12, 2017

Double clicking on a value in the raw tab seems to have no effect. p.s I asked twice in Discord with no response. I guess I'm finally getting old enough that I don't understand how to use new platforms ;) ----- Cheers, Sean -- View this message in context: http://forum.world.st/Did-we-lose-edit-in-place-in-GT-Inspector-in-Pharo-6-… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

what is the SpecLayout architecture?
by Peter Uhnak March 12, 2017

March 12, 2017

Hi, this is probably a tall order, but is there some description of SpecLayout architecture? To clarify: I am NOT asking how to use SpecLayout, I am asking how SpecLayout works internally. iirc SpecInterpreter was rewritten by Johan & Stef, so maybe you guys have some notes? Thanks, Peter

class selection is lost when browsing a method in and switching in hierarchy mode
by stepharong March 12, 2017

March 12, 2017

Hi I have the impression that I found an really annoying glitch. - Take a class hierarchy in the middle - Select a class side method - Select the hierarchy buttong - normally the class you selected and (the class of the currently displayed is not selected anymore). https://pharo.fogbugz.com/f/cases/19828/Class-side-methods-hierarchy-select… --

Why do we have doublequoting for "?
by stepharong March 12, 2017

March 12, 2017

about quoting ;( Hi I have a string '<li> Stéphane Ducasse and Damien Pollet, Fingerprints, Journal of Information System, 2010. </li> ' and when I do printIt in the debugger I get the following "'<li> Stéphane Ducasse and Damien Pollet, Fingerprints, Journal of Information System, 2010. </li> '" I do not get why we doublequote the character " inside string. It means that I have to remove all the " inside to string to be able to express tests. Stef
