Warning in Pharo 5
by Cyril Ferlicot D. Feb. 1, 2016

Feb. 1, 2016

Is it me that did something wrong or in Pharo 5 the warnings open a debugger instead of a Warning window with the explanation? -- Cyril Ferlicot http://www.synectique.eu 165 Avenue Bretagne Lille 59000 France

Rubric: spotter with preview leaks some memory
by Nicolai Hess Feb. 1, 2016

Feb. 1, 2016

Open fresh image 50536 Open Spotter, enable preview (cmd+p) search for EllipseMorph dive in instance-methods scroll through the list one item after another. open playground evaluate RubTextLine allInstances size. "553896" case 17421 is related to this, but does not fully solves this. please review and comment on that fix, so we can integrate this soon. The problem sometimes remains even with this fix. The memory (instance count of RubTextLine) just grows in the background

Unused ugly morph methods...
by stepharo Feb. 1, 2016

Feb. 1, 2016

I really hope that Bloc will forbid such systematic submorphs use because it leads to code like that. Stef submorphNamed: aName ^ self submorphNamed: aName ifNone: [nil] submorphNamed: aName ifNone: aBlock "Find the first submorph with this name, or a button with an action selector of that name" self submorphs do: [:button | | sub args | (button respondsTo: #actionSelector) ifTrue: [button actionSelector == aName ifTrue: [^button]]. ((button respondsTo: #arguments) and: [(args := button arguments) notNil]) ifTrue: [(args at: 2 ifAbsent: [nil]) == aName ifTrue: [^button]]. (button isAlignmentMorph) ifTrue: [(sub := button submorphNamed: aName ifNone: [nil]) ifNotNil: [^sub]]]. ^aBlock value

Morph should not query Color for nil :(
by stepharo Jan. 31, 2016

Jan. 31, 2016

Morph>>colorString: aColor aColor ifNil: [ ^'nil' ]. ^aColor name ifNil: [ aColor storeString ] ifNotNil: [ :colorName | 'Color ', colorName ] such behavior should be moved to Color. The problem is not Morphic per se. This is that OO design was often not considered. Stef

ProcessTest>>testSchedulingIsFirstComeFirstServed
by Ben Coman Jan. 31, 2016

Jan. 31, 2016

My general understanding of process scheduling is that it is FIFO within same priority. Indeed Pharo has a test for this ProcessTest>>testSchedulingIsFirstComeFirstServed, which however I thought was a bit fragile and I was looking to revise. But now I'm curious whether same-priority-process FIFO scheduling is an expected guarantee? On both Pharo 5 build 50560 & Squeak 5 build 15113 the following test fails... [ 1 to: 100000 do: [ :n | | ranFirst ranSecond | [ [ ranFirst ifNil: [ ranFirst := 1 ] ifNotNil: [ ranSecond := 1] ] forkAt: 78. [ ranFirst ifNil: [ ranFirst := 2 ] ifNotNil: [ ranSecond := 2] ] forkAt: 78. ] forkAt: 79. self assert: ranFirst=1. self assert: ranSecond=2. ] ] fork. ... but only after 20k iterations, which seems an "almost" guarantee. Interestingly, it doesn't fail when run without the outer fork. Also if I take an alternate approach with less message calls... faults := OrderedCollection new. done := Semaphore new. [ 1 to: 10000000 do: [ :n | | ranFirst ranSecond | [ [ ranFirst ifNil: [ ranFirst := 1 ] ifNotNil: [ ranSecond := 1] ] forkAt: 78. [ ranFirst ifNil: [ ranFirst := 2 ] ifNotNil: [ ranSecond := 2] ] forkAt: 78. ] forkAt: 79. (ranFirst=1 and: ranSecond=2) ifFalse: [ faults add: { n . ranFirst . ranSecond } ]. ]. done signal. ] fork. done wait. faults inspect. I only get seven failures in 10 million iterations. "an OrderedCollection( #( 258535 2 1) #(1148605 2 1) #(3502820 2 1) #(4010935 2 1) #(4533713 2 1) #(6301878 2 1) #(8497001 2 1))" So what I'm wondering is if there is a bug to hunt down, or if FIFO scheduling is simply not an expected guarantee? cheers -ben

Disable assertions (design by contract)
by Aliaksei Syrel Jan. 30, 2016

Jan. 30, 2016

Hi Assertions play an important role in design by contract. It is great to have assertions in Pharo out of box (Object>>#assert:). However in projects with many post- and precondition as also class invariants heavy usage of assertions decreases performance... Would it be possible to have a compiler setting (in setting browser) to enable/disable assertions and not compile them to bytecode? Compiler should ignore the whole assertion statement with removed condition. For example: > self assert: self hugeInvariant. with disabled assertion hugeInvariant must not be sent. Thanks, Alex
