Nope! Thanks for the link. It's just a very small part of my paper anyway; so it's good to have a more elaborate reference. Basically this is where I'd like to plug in active context.

Re: [Pharo-project] Issue 3957 in pharo: MethodWrappers left method after uninstall

by pharo＠googlecode.com

Comment #1 on issue 3957 by marianopeck: MethodWrappers left method after uninstall http://code.google.com/p/pharo/issues/detail?id=3957 Thinking about that, I think that's a bug. I mean, you want to install the wrapper in the class Foo. For me, it should not follow the lookup. It should do just a oldMethod := self wrappedClass methodDict at: self selector which will throw an error if the selector is not defined in the class. I think that doing the lookup can be dangerous. Maybe adding another method like: ObjectAsMethodWrapper onClassOrSuperclasses: Foo selector: #hash that does what is now... what do you think ?

[Pharo-project] Issue 3957 in pharo: MethodWrappers left method after uninstall

by pharo＠googlecode.com

Status: New Owner: ---- New issue 3957 by lem...(a)gmail.com: MethodWrappers left method after uninstall http://code.google.com/p/pharo/issues/detail?id=3957 Pharo image: Pharo 1.2.1 Latest update: #12345 Virtual machine used: 'Croquet Closure Stack VM [StackInterpreter VMMaker-oscog-IgorStasenko.54]' Class browser used (if applicable): OB Steps to reproduce: 1. create a new class, example Foo 2. install a method wrapper on Foo, on a selector non defined locally. 3. uninstall the method wrapper. 4. now you have the method defined locally, with the inherited behavior. Example: | a | a := ObjectAsMethodWrapper on: Foo selector: #hash. a install. a uninstall. Now you have a hash method on Foo, that should not be there. One solution is to add something like this to the install code: (self wrappedClass localSelectors includes: self selector) ifTrue: [needCleanUp := false.] ifFalse: [needCleanUp := true]. And this to the uninstall code: needCleanUp ifTrue: [self wrappedClass removeSelector: self selector]

So yes, or a better name or...... if someone really needs to know that the build script was, then it means: 1) that he is aware of PharoCore / PharoDev 2) That he wants to reproduce the build, or fix a bug, or something. For me, both thins means that such guy is not a beginner/newbie. So we can assume that he also knows where to search such file in hudson ? if true...then we don't include the file... > > Marcus > > > -- > Marcus Denker -- http://www.marcusdenker.de > INRIA Lille -- Nord Europe.
