---------- Forwarded message ---------- From: Mark Rizun <mrizun(a)gmail.com> Date: Mon, Jun 2, 2014 at 4:19 PM Subject: [Pharo-users] [SummerTalk] Refactoring in Pharo To: Any question about pharo is welcome <pharo-users(a)lists.pharo.org> Hi guys! I'm happy to announce you, that I will be working on SummerTalk project entitled "Refactoring in Pharo" with RMoD. Obviously, it's about refactoring system in Pharo. The goal of this project is to improve existing refactrings in Pharo and add some new ones. If you are interested in this topic please visit my blog for more details: http://myfuncoding.blogspot.com/ After some work is done, I'll publish info here and on my blog. Also, source code will be available on my smalltalkhub, and it's going to be soon ;) Thoughts and feedback are welcome. Cheers, Mark -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm." Winston Churchill

String deduplication
by Philippe Marschall June 2, 2014

June 2, 2014

Hi This is an idea I stole from somebody else. The assumption is that you have a lot of Strings in the image that are equal. We could therefore remove the duplicates and make all the objects refer to the same instance. However it's not a simple as that. The main issue is that String has two responsibilities. The first is as an immutable value object. The second is as a mutable character buffer for building immutable value objects. We must not deduplicate the second kind. Unfortunately it's not straight forward to figure out which kind a string is. The approach I took is looking at whether it contains any 0 characters. An other option would be to check whether any WirteStreams are referring to it. Also, since there are behavioral differences between String and Symbol besides #= we must exclude Symbols (eg. there is #'hello' and 'hello' in the heap and they compare #= true but we must not make anybody who refers to 'hello' suddenly refer to #'hello'). Anyway here's the code, this saves about 2 MB in a fairly stock Pharo 3 image. Sorry for the bad variable names. | b d m | b := Bag new. d := OrderedCollection new. m := Dictionary new. "count all string instances" String allSubInstancesDo: [ :s | s isSymbol ifFalse: [ b add: s ] ]. "find the ones that have no duplicates or are likely buffers" b doWithOccurrences: [ :s :i | (i = 1 or: [ s anySatisfy: [ :c | c codePoint = 0 ] ]) ifTrue: [ d add: s -> i ] ]. "remove the ones that have no duplicates or are likely buffers" d do: [ :a | a value timesRepeat: [ b remove: a key ] ]. "map all duplicate strings to their duplicates" String allSubInstancesDo: [ :s | s isSymbol ifFalse: [ (b includes: s) ifTrue: [ | l | l := m at: s ifAbsentPut: [ OrderedCollection new ]. l add: s ] ]. "remove the duplicates" m keysAndValues do [ :k :v | | f | f := v at: 1. 2 to: v size do: [ :i | (v at: i) becomeForward: f ] ] Cheers Philippe

Advice for a newb
by Rick Kitts June 2, 2014

June 2, 2014

Hello. I was wondering if anyone could point me to or otherwise suggest some best practices for working on Kernel code. Iâm futzing about with the Duration class (in the interest of fixing 13215) and have discovered that itâs really easy to crash Pharo if I break that class. I assume there are other classes that would exhibit the same behavior. I suppose I could just be really cautious and save my image after every change but that seems so error prone that Iâm hoping that there are idiomatic ways of working on kernel code (beyond just save ones image early and often) so I donât lose work. Iâm asking because the naive solution (copy the original class, modify it to suit, delete the original and rename the new class to the original) of course doesnât work. TIA for any suggestions or assistance and apologies in advance if this is RTFM, I didnât see anything (didnât look very hard either though). âRick
