[Pharo-project] Cog - dumb question
by Schwab,Wilhelm K June 23, 2010

June 23, 2010

In skimming the messages, I thought I read both that an image saved from a Cog VM both can and cannot be later opened with an ordinary VM. Which is it? It makes sense for the image to have to include Cog support code, but does that and being saved from a Cog VM spoil the image for the current closure VMs? Bill

[Pharo-project] Why announcer subscriptions is dectionary?
by Denis Kudriashov June 22, 2010

June 22, 2010

Hello, I found that subscribers handle announcements in order differ then order in which they subscribe. Reason - announcer subscriptions is dictionary. Maybe dependency of announcement handling order is bad code design. But it can be usefull. Example. I need announcerA delegates announcements from another announcerB. And I need announcerA handles some specific announcement for own task. I try this code: announcerB on: SpecificEvent send: #specificHandler: to: announcerA. announcerB on: Announcement send: #announce: to: announcerA I want announcerA handles SpecificEvent (by #specificHandler) before other subscribers to announcerA .With current announcements implementation this code not work. What you think about this? I see announcer implementation. And I dont found some reason for dictionary subscriptions. Maybe we can fix it.

>any trouble? This update is still not available. >http://pharo.gforge.inria.fr/updates/pharo1.2/updates.list Yes, I'm also not able to update from 12011 to 12012. Is this related to Cog since 12011 included changes for that. And I think the topic of the mail should be "[update 1.2] #12012" since it belongs to 1.2.

(see http://code.google.com/p/pharo/issues/detail?id=1803) Looks like Juan's fix is not (yet) included in Cog VM. Which also leads to the following questions 1. will Cog development continue in parallel or be folded back into the usual VM's from www.squeakvm.org. 2. where is the best place to discusss Coq related issues, currently people discuss on squeak, pharo and vm-list. -> I would vote for the VM list Bye T.

Hi Eliot, havent had the time to play with it - but your announcement was already a real surprise. I know that is amazing work and by making it available we can all profit and learn from it! I hope our community is able to help moving it forward, report and fix bugs and by doing so give you and Teleplace something in return. Thanks to all who helped making this possible!

Some people asked me how I got Pharo to run on Cog on OS X. Here's how: 1. Download the Cog source-code from <http://ftp.squeak.org/Cog/OpenSourceCog.tar.gz>, open the Xcode project CoreVM.xcodeproj, and compile the thing. For those who want to skip this step I've put the resulting binaries here: <http://www.lukas-renggli.ch/dropbox/cog-osx.zip>. 2. Open a (copy of a) Pharo image in an **old** VM and file-in the appropriate change-set (there is one for Pharo 1.0 and one for Pharo 1.1) from the following issue report: <http://code.google.com/p/pharo/issues/detail?id=2579>. Save the image and quit. 3. Open the image in the Cog VM. Note that if you safe the image, you won't be able to open it again in a non-Cog VM. Hopefully John will provide a properly built binary soon :-) Don't try Seaside, it won't work. Cog does not (yet) support the stack manipulation tricks yet.

[Pharo-project] Getting all senders of a CompiledMethod, best solution ?
by laurent laffont June 22, 2010

June 22, 2010

Hi, I have this method in AutotestFinder, I don't like it, someone has better code ? AutotestFinder>>allSendersOf: aCompiledMethod "Returns all senders as a collection of CompiledMethod" | methodReferences senders | methodReferences := (SystemNavigation default allSendersOf: aCompiledMethod selector). senders := methodReferences collect: [:aMethodReference | aMethodReference actualClass lookupSelector: aMethodReference selector]. ^ senders select: [:sender| sender isNil not]. "Why senders contains nil sometimes ?" What it does: AutotestFinder new allSendersOf: (ProfStef lookupSelector: #go) answers: an OrderedCollection((ProfStef>>#go "a CompiledMethod(10485760)") (ProtoObject>>#initialize "a CompiledMethod(326631424)") (ProfStef class>>#go "a CompiledMethod(49807360)") (ProfStef class>>#initialize "a CompiledMethod(1060634624)") (ProfStefBrowser class>>#menuCommandOn: "a CompiledMethod(340262912)") (ProfStefTestGo>>#testGoOpenSmalltalkSyntaxTutorial "a CompiledMethod(249823232)")) Cheers, Laurent Laffont http://pharocasts.blogspot.com/ http://magaloma.blogspot.com/
