I also tried composition in Cuis4.2 which is interesting because it uses the primitive 103, but is around 111ms for other reasons | text | text := Compiler evaluate: (FileStream fileNamed: 'text_cuis.st') contentsOfEntireFile.

Start with a trivial improvement!
by Marcus Denker Oct. 12, 2013

Oct. 12, 2013

One nice way to get in the mood of doing (and at the same time testing the system) is to start with trivial improvements. This is especially nice as a "starter" when you never contributed any change to Pharo. And by trivial I mean *really* mean trivial: -> a typo in a comment -> remove a temp not accessed -> clean out some trivial dead code -> do a simplistic refactoring of a bad smell, even inside a single method -> document something -> structure bad stuff better so it is easier to replace later Taken in itself, single changes like these have no influence, but: -> they get you in a mood of doing. -> they make you feel that Pharo is "owned" by you. -> take 1000 of those trivialities and they *do* make a difference. -> next time something bothers you, you will have the context of "I can just fix it". The critic tools is one way of finding these places, another is to just note down every time you see a triviality and later go through that list. The bug tracker can be source, too. Marcus

external semaphoresâ¦again
by Norbert Hartl Oct. 12, 2013

Oct. 12, 2013

As I need an image that runs longer than 24 hours I'm looking at some stuff and wonder. Can anybody explain me the rationale for a code like this maxExternalSemaphores: aSize "This method should never be called as result of normal program execution. If it is however, handle it differently: - In development, signal an error to promt user to set a bigger size at startup immediately. - In production, accept the cost of potentially unhandled interrupts, but log the action for later review. See comment in maxExternalObjectsSilently: why this behaviour is desirable, " "Can't find a place where development/production is decided. Suggest Smalltalk image inProduction, but use an overridable temp meanwhile. " | inProduction | self maxExternalSemaphores ifNil: [^ 0]. inProduction := false. ^ inProduction ifTrue: [self maxExternalSemaphoresSilently: aSize. self crTrace: 'WARNING: Had to increase size of semaphore signal handling table due to many external objects concurrently in use'; crTrace: 'You should increase this size at startup using #maxExternalObjectsSilently:'; crTrace: 'Current table size: ' , self maxExternalSemaphores printString] ifFalse: ["Smalltalk image" self error: 'Not enough space for external objects, set a larger size at startup!' "Smalltalk image"] I have reported this once but got no feedback so I like to have a few opinions. The report is here: https://pharo.fogbugz.com/f/cases/10839/ Norbert
