Re: [Pharo-users] Anonymous classes performances

by Steven Costiou

You can find the code below. I just change the call to m by m1 to test the two methods. I started again in a fresh pharo 6 image and now the results seem all similar for the following code. I will do all my tests again to see if it was my fault but it takes a lot of time (2 hours for each full test). What sould be the expected results ? Should an instance of an anonymous class be as fast as a regular instance when calling the same code, being defined in the anon class or its super class ? A implements m ^100 printString and B subclass of A implements m1 ^100 printString a := B new. class := A newAnonymousSubclass addSlot: (InstanceVariableSlot named: #y); compile: 'm1 ^100 printString'; yourself. c := A new becomeForward: class new. res := Dictionary new. col1 := OrderedCollection new. col2 := OrderedCollection new. 10000 timesRepeat: [ Smalltalk garbageCollect . col1 add: [1000000 timesRepeat: [ a m ]] timeToRun]. 10000 timesRepeat: [ Smalltalk garbageCollect . col2 add: [1000000 timesRepeat: [ c m ]] timeToRun]. res at: 'a' put: col1. res at: 'c' put: col2. res inspect Steven.

Hi Steven.

Anonymous classes performances

by Steven Costiou

I have been playing a bit with anonymous subclasses, and instances of anon subclasses seem slower to execute code than "regular" subclasses instances, but sometimes they reach equivalent performances (for code defined in anon-subclasses). I don't understand why. I have a class A with a method m. B is subclass of A with a new method m1. Anon-A is an anonymous class of A which also implements the m1 method. I did various tests of speed and: - when executing m, compiled in A, instances of Anon-A are around 10% slower than instances of B - when executing m1, compiled in B and in Anon-A, performances are equivalent between instances of B and of anon-A Is that a particular behavior of anonymous subclasses, like their instances can easily find behavior defined in their class but have to perform extra-work to find methods defined in their superclass (which is not anonymous) ? Is that vm related ? Other ? Steven.

Thank you very much! Now, I understand. However, it's not *that* obvious. Your excellent POST: example really should be in the documentation.

Can not save the source file

by Marc Hanisch

Hello, when I open up my Pharo6.0 image and left+click > save as... to save my image, Pharo tells me that it could no save the source file. Unfortunately the message disappears too fast, so I can not paste it here ;-) I've checked the Pharo version I've downloaded and the sources-file is present: # ls -l shared drwxrwxr-x 2 marc marc 4096 Jun 9 14:40 icon-packs -rw-r--r-- 1 marc marc 1361267 Jun 9 15:48 Pharo6.0.changes -rw-r--r-- 1 marc marc 36798736 Jun 6 15:24 Pharo6.0.image -rw-rw-r-- 1 marc marc 43775 Jun 9 15:47 PharoDebug.log drwxrwxr-x 6 marc marc 4096 Jun 8 15:21 pharo-local -rw-r--r-- 1 marc marc 36114887 Jun 6 15:24 PharoV60.sources Any hints what I'm missing?
