[Pharo-project] ObjectFinalizerTests understanding problems
by Norbert Hartl June 17, 2008

June 17, 2008

Before I recognized that Adrian fixed the ObjectFinalizerTests>>testFinalizationOfEquals I gave it try myself. I came to the same conclusion as Adrian how to fix. But now after knowing how it works I do not know why the test succeeds :) The test uses 1 to: 5 do: [:n | o := Object new. bag add: n. o toFinalizeSend: #remove: to: bag with: n]. 1 to: 5 do: [:n | o := Object new. bag add: n. o toFinalizeSend: #remove: to: bag with: n]. My problem is that toFinalizeSend:to:with adds an Objectfinalizer to the finalizationRegistry of the instance. But Object>>finalizationRegistry "Answer the finalization registry associated with the receiver." ^WeakRegistry default returns a global object which is WeakKeyDictionary. And | d | d := WeakKeyDictionary new. d at: (1 asString copy) put: $a. d at: (1 asString copy) put: $b. d size prints 1. To me that would exchange every entry from the first run by the second run (because the objects are equal). So I would assume that if there does not happen a run of the garbagecollector between the two loops the objects of the first loop should be still contained in the bag. But the test is named finalizationOfEquals so I have to assume: self doesNotUnderstand Can someone explain it to me, please? Norbert

[Pharo-project] Namespaces?
by Michael Rueger June 16, 2008

June 16, 2008

Hi all, asking the unmentionable ;-) Are there any plans for (simple) name spaces in Pharo? Reason I'm asking is that it would make moving code between e.g. VW and Pharo easier IMHO. Michael

Hi all if somebody wants to add a really cool feature to the debugger.... in VW we can see as intermediary variable the results of subsets of expression so we we step thru the execution we do not have to select the expression and print it all the time we can simply see the results in the variable.

[Pharo-project] call for fix: fixing browser names and stupid dead navigation that works
by StÃ©phane Ducasse June 15, 2008

June 15, 2008

Hi guys I send to this list the email I sent to the great omnibrowser developer list...... Really cool features but seems to forget the basic. if it takes me more than 5 min to find something may be the interface is BAD. Stef how with the new browser can I get class Variable refs? I ask this question for OB-Shittynamebrowser and OB- shittynamepackagebrowser. Do you expect that a newbie can find his way with browser named like that? this question quite stupid question reveals that the command if there exist are far from readable for a normal programmer. Of course feel free to think that I'm an idiot. When somebody instead of inventing new features will do a real usability analysis? Stef

Hi Stef, you somehow missed the updates in System from the FixUndeclared Slice. The class variables SmallPrimes and HighBitOfByte are still missing. Norbert
