[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.

Re: [Pharo-project] ODBCWarning

by Schwab,Wilhelm K

Also, some tests of this type would have saved me some time. First I was looking for a problem in my code, and it took a bit too long for me to question whether the ODBC package still worked. It does, but just differently than when I originally tested it. Tests would have not made that very obvious, both by verifying functionality and serving as coding examples.

Question : I know it's usually not recommended to test stuff that requires external output (such as setting up user, password, DSN, etc) but I think we should design a very simple database, on all those RDBMS and use SUnit to automate testing.

The latest ODBC offering appears to work, but in fairness to me, it does not work the same way it did (some time ago) when I crossed database access off of my potential-show-stopper list. Re the warnings about change of language, for some strange reason, I find it very easy to believe that this is a Microsoft idiosyncrasy and so I added a suitable #on:do: to capture the warning. That could be bad though; better ideas are welcome. The problem I had going from Linux to Windows will probably persist. Of course, I would like to see the startup/shutdown system revised to make such things easier to get right, after which it would hopefully become short work to fix. The ODBC package derives ODBCRow from IdentityDictionary and ODBCResultSet from Stream. IMHO, it always seems cleaner to compose rather than inherit the limited functionality that the base class provides. However, the inheritance is not really hurting anything here; socket addresses being inherited from byte arrays *is* hurting us. I brushed up against that at one point, but was able to work around it. When it gets between me and something I need, I will introduce an InternetAddress class and try to lazily resolve names and addresses, fix the printing, etc. Bill -----Original Message----- From: pharo-project-bounces(a)lists.gforge.inria.fr<mailto:pharo-project-bounces@lists.gforge.inria.fr> [mailto:pharo-project-bounces@lists.gforge.inria.fr<mailto:pharo-project-bounces@lists.gforge.inria.fr>] On Behalf Of Schwab,Wilhelm K Sent: Tuesday, September 01, 2009 3:15 PM To: Pharo-project(a)lists.gforge.inria.fr<mailto:Pharo-project@lists.gforge.inria.fr> Subject: [Pharo-project] ODBCWarning The porting continues...

One thing really surprised me, and note that I might have brought this on myself (though I think that is unlikely) by messing with startup and shutdown: the ODBCLibrary was stubbornly clinging to the Linux library from my home machine. I finally used ODBCLibrary default initialize. which seemed to put an end to the separation anxiety. Is there a better fix? I suppose I should try this in a clean image to see if there is really a problem therein, but that will be a little hard to do without a lot of my code, almost any of which either depends on changes I have made or could have caused the problem. Maybe I should ask whether some of you use ODBC on Windows and Linux and have no problems moving between the machines.

I have used #readStream and variants for a long time; I think you will like it if you try it. The code is cleaner, avoids a set of parentheses at each call, and one can always create variants on it when more control is necessary.
