[Pharo-project] TestNewParagraphFix

by Sean P. DeNigris

NewParagraph is deprecated in 1.4. TestNewParagraphFix doesn't actually mention NewParagraph directly. The class comment says "This class tests the same things as its superclass, but for NewParagraph which is used in the Morphic environment." but its superclass is TestCase. Is TestNewParagraphFix still relevant? What was the original motivation i.e. why is it called XxxFix?

Re: [Pharo-project] VM freezes sending #basicNew to Stream subclass

by Marcus Denker

Hi, We had a look and the problem is that printOn: on Stream is defined to print the contents of the Stream even though it might not be initialized yet (e.g. when creating a Stream instance with #basicNew). The simplest solution is to just not print the contents of Streams in #printOn: http://code.google.com/p/pharo/issues/detail?id=5047 Stream should not print its contents in printOn: Reason: => Debugging leads to change the state of Stream when looking at it => Network streams load all content => unitialized Streams has undefined behavior for printing Solution: remove #printOn: On Fri, Dec 2, 2011 at 9:08 AM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> wrote: >>>> >>>> I only had a look in Pharo 1.4 >>>> It sounds like a subtle bug related to introduction of >>>> SubclassResponsibility in Pharo. >>>> If you revert Object>>subclassResponsibility to its previous version >>>> you get a more reliable error. >>> >>> What would be your hypothesis?

[Pharo-project] Test Categories

by Sean P. DeNigris

There's Tests-System - tests for various sub-categories of System Tests-SystemSupport - notice no second dash Tests-Polymorph-Widgets - with second dash I was going to change the first two to be like the last one (which is most like the category under test). But I know there are weird dash issues because of Monticello, so I wanted to ask first...
