Re: [Pharo-project] Cleaning morphic?

by Mariano Martinez Peck

Guille: I developed a couple of tools that may help you. The first one is a tool to discover the classes that were used for a particular time duration or block. http://www.squeaksource.com/ClaseUseDiscovery You should read: http://forum.world.st/ANN-ClaseUseDiscovery-tool-tp1296859p1296859.html On the other hand, you can also try to replace each CompiledMethod of Morphic by a MethodWrapper that just logs its name or something like that. Then you can know which methods were executed. In the dev image 1.1 there is already the package MethodsWrapper from the repository: http://www.squeaksource.com/ObjectMetaTools In the package ObjectMetaTools of the same repository, you have ProtocolCatcher. Check its class comment. Finally, I think a very good idea is to use Adrian Lienchard DTrace integration to the VM: http://forum.world.st/ANN-DTrace-for-Squeak-Pharo-td2173422.html#a2173422 So...what I am saying with all these is that probably, search senders is not enough to clean Mprhic, as Levente said. I would take a dev image, and I would load big projects, like Moose (complete complete), Dr Geo2, etc, and I would use the tools, run all the tests, and check on runtime what is being really used.

[Pharo-project] Is SystemChangeNotifier notifying about protocol changed (with what changed)?

by StÃ©phane Ducasse

Hi guys I'm trying to work on the integration of the new Rapckage implementation and for this I'm trying to shield myself from event and building system anouncements.... Now when a protocol is added in a class, I get a reorganized event but I do not get the changed element.... And I checked and I see that: notifyOfChangedCategoriesFrom: oldCollectionOrNil to: newCollectionOrNil (self hasSubject and: [oldCollectionOrNil ~= newCollectionOrNil]) ifTrue: [SystemChangeNotifier uniqueInstance classReorganized: self subject]. Am I correct to think that systemNotification does not raised what changed :( arghhhhhhh Stef

Re: [Pharo-project] [Vm-dev] VM more flexible for research?

Well here is a non-obvious solution. (a) take your handy Pharo image and convert it to 64 bits. (b) take your handy 64bit VM that runs 64bit images, I believe you can build one for any platform. (c) exploit the 32 extra free bits you'll find in the header. On 2010-07-15, at 6:30 AM, Mariano Martinez Peck wrote: > Hi folks. I am a newbie for both research and VM.
