I'm really hot to get my hands on this because I'm getting my son started on Squeak by Example after your excellent book 'Learning Squeak with Robots' But I want him to learn Pharo because the overall goal is to get him into Seaside and Webapps. Now would be the perfect time to get this book for us anyway. Thanks! P.S. BTW, He set up a blog on his own, with pix he created with the ideas he got from Learning with Robots: Sorry, this is a bit off-topic. DZ

Re: [Pharo-project] runaway Pharo beta image

by Adrian Lienhard

Hi Paul, A likely scenario is that you have a process in an endless loop (probably the one in ByteString(String)>>encodeOn:). Its stack grows and uses more and more memory. The first thing to try is control-. (or apple-.), which should interrupt the current process. If the GUI is still responsive you can also open the process browser (in the Tools menu) and try to debug or just terminate the offending process.

[Pharo-project] runaway Pharo beta image

by Paul DeBruicker

Hi - I have done something to my image and don't know how to fix it. When it opens it maximizes one of the processors and allocates a large amount of RAM to itself. When I attempt to run the Debug > Start profiling all Processes it crashes the vm after I move the mouse to the top of the screen. When I run Process allInstancesDo: [ :p | | rules | rules := ProcessBrowser nameAndRulesFor: p. rules second ifTrue: [ p terminate ] "1=name, 2=safe-to-kill, 3=safe-to-debug" ]. from here: http://wiki.squeak.org/squeak/1799 nothing changes. Printing 'ProcessBrowser new processList' in a workspace gives: a WeakArray(a Process in Delay class>>handleTimerEvent a Process in SystemDictionary>>lowSpaceWatcher a Process in [] in Delay>>wait a Process in WeakArray class>>finalizationProcess a Process in nil a Process in ByteString(String)>>encodeOn: a Process in [] in BlockClosure>>newProcess) And the VM statistics are: uptime 0h8m53s memory 1,055,051,120 bytes old 1,050,497,028 bytes (99.6%) young 83,708 bytes (0.0%) used 1,050,580,736 bytes (99.6%) free 4,470,384 bytes (0.4%) GCs 4,999 (107ms between GCs) full 3 totalling 18,400ms (3.0% uptime), avg 6133.0ms incr 4996 totalling 120,999ms (23.0% uptime), avg 24.0ms tenures 112 (avg 44 GCs/tenure) Are there other things I can do to get it back under control or should I just save everything in some MC repositories and set up a new image? I'm reluctant to do that now because I don't know what I did to create the situation I'm in. Thanks for your help Paul

Re: [Pharo-project] [ANN]

by Schwab,Wilhelm K

Stef, IIRC, Object Arts started promoting name spaces at one point, and (my best guess) ended up finding a very interesting solution using messages. I believe they call the result an environment, and by asking something for its environment that in turn understands messages to access classes one can do things like Smalltalk stef browser show. Smalltalk bill browser show. Where #stef and #bill provide our respective environments, and #browser answers a class. I'm not sure if that is at all relevant - free advice is often worth what we pay for it :) Bill -----Original Message----- From: pharo-project-bounces(a)lists.gforge.inria.fr [mailto:pharo-project-bounces@lists.gforge.inria.fr] On Behalf Of StÃ©phane Ducasse Sent: Friday, September 04, 2009 3:05 AM To: Pharo-project(a)lists.gforge.inria.fr Subject: Re: [Pharo-project] [ANN] Yes but if we want to make sure that we could plug easily a new stream library we should either use virtual classes (quite difficult and major changes at language level) or readStream So readStream gives us a nice solution.
