[Pharo-project] latest build yields stack trace running #cleanUpForProduction
by Yanni Chiu Jan. 18, 2012

Jan. 18, 2012

Using Pharo 1.4 (#220), I end up in: ByteSymbol(Object)>>doesNotUnderstand: #run:with:in: which was called from: (MCPackage named: self theScriptLoaderPackageName) unload. First I thought it was because I had OSProcess loaded when I ran cleanUpForProduction, and it stopped in an OSProcess class. Without OSProcess, the I got a slightly different problem: the doesNotUnderstand of #run:with:in: is due to something in #cleanUpForRelease. Trying to debug it, new debuggers pop up, and then the emergency evaluator. I have Seaside30/Magritte/Pier loaded, so I can try without those too. But, it used to work with all these things loaded. -- Yanni

[Pharo-project] Question about #becomeForward
by Sven Van Caekenberghe Jan. 18, 2012

Jan. 18, 2012

Hi, I want to create an array that references itself in its second element like this | array | array := #(1 nil). array at: 2 put: array. array I thought that the following would work | array elements | array := Array new. elements := Array with: 1 with: array. array becomeForward: elements. array And it does in a workspace, but not in my code where it looks like this parseArray | array elementsArray | array := Array new. self storeReference: array. elementsArray := self parseArrayInternal. elementsArray size > 0 ifTrue: [ array becomeForward: elementsArray ]. ^ array The #become[Forward] is necessary because the array size is not known up front and one of its elements might refer to itself, possibly deeper down. So I guess I am doing something wrong, the question is what ? Or is there another way to achieve the same effect ? Thx, Sven

[Pharo-project] First steps making OB work in 1.4
by Guillermo Polito Jan. 17, 2012

Jan. 17, 2012

Hi! I've been working the last days in making OB work in pharo 1.4. I updated several deprecations like method reference and stuff and discovered some bugs that I've already published in: http://code.google.com/p/pharo/issues/detail?id=5189&q=milestone%3D1.4&cols… http://code.google.com/p/pharo/issues/detail?id=5183&q=milestone%3D1.4&cols… I've already proposed some fixes for them, but if anyone can have a look too I'll feel better :). Those fixes are needed in order to load OB. Meanwhile, you can also have some patches from the cs and fileout I attach. What's working now? OB + OCompletion + Shout + Sunit integration. So, It's everything but Refactoring browser, which is a little more difficult since there is another RB version loaded in the image :P. To load it (after integrating the patches): Gofer it squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfOmniBrowser'; load. (ConfigurationOfOmniBrowser project version: #stable) load: #( 'Core Tests' 'OCompletion Tests' ) , #( 'Core' 'OB-SUnitIntegration' 'OB-Shout' 'OCForOB'). Cheers, Guille
