How to inspect a variable in a squeakimage dump file?
by peterblunk＠arcor.de 08 Dec '12

Hello list! How to inspect a variable in a squeakimage dump file? What do i have? * a Squeak 3.9 image runnung on a squeak4.10.2-2612 VM has run out of memory. The image is still in memory (size:560MB on windows 2003 pc), showing the dialogbox to confirm the crash. * a dumpfile of this process createt with userdump.exe * a copy of the squeakimage five hours earlier to the crash i expect the imagestructure to be in a valid state. (except not enough memory) What do i want? i want to inspect the contents of some variables in the image (dump file) So the Question is where can i read on / find more information about locating a certain variable in the image (dumpfile) to inspect its contents. Any advice, pointers or links are very welcome Peter

So the question is, do we get the Ulam spiral creation code snippet included in Squeak 4.4? --Hannes On 10/3/12, Jecel Assumpcao Jr. <jecel(a)merlintec.com> wrote: > Hannes.

squeak.org updated
by Chris Cunnington 06 Dec '12

06 Dec '12

http://box3.squeak.org:8624/ I killed the old process which had been up for 430 hours. It had been posted on The Weekly Squeak and I never saw it go down. So, I'm thinking Altitude is pretty stable. I removed the large Take Part In The Innovation (TPITI) section and made it one of the six smaller ones. I added two links (i.e. World Of Smalltalk and Planet Squeak) to the Smalltalk Blogs. I think Hannes wins this round. The TPITI looks better as a smaller section, which allows the entire page to be seen without scrolling downward. Chris

[ [5 seconds asDelay wait] valueWithin: 2 seconds onTimeout: [] ] durationToRun --> 0:00:00:02.001 so far so good [ 3 timesRepeat: [ [5 seconds asDelay wait] valueWithin: 2 seconds onTimeout: []] ] durationToRun --> 0:00:00:06.001 seems ok [ [ [5 seconds asDelay wait] valueWithin: 2 seconds onTimeout: [] ] valueWithin: 3 seconds onTimeout: [] ] durationToRun --> 0:00:00:02.001 alright BUT: [ [ 3 timesRepeat: [ [5 seconds asDelay wait] valueWithin: 2 seconds onTimeout: []] ] valueWithin: 3 seconds onTimeout: [] ] durationToRun --> 0:00:00:05 ?

Cog VM crash dump
by Stéphane Rollandin 06 Dec '12

06 Dec '12

Hello, Attached is a crash dump of the (I think) latest Cog VM on Windows 7. The crash happens when after double-cliking Croquet.exe I select the image I want to open. Strangely it does not always happen though. Stef

Cannot debug from Process browser
by Chris Muller 06 Dec '12

06 Dec '12

A few times lately I have noticed I can no longer open a debugger from the Process browser (via Command+d). As soon as I select it the image locks up. If I break in with Command+. right away I was able to do some minimal tracing. It appears the Process instance I want to debug; his #nextLink is himself. This results an endless recursion when his printing method simply tries to ask his #size. Incidentally, the Process I wanted to debug was simply waiting on a Semaphore of a network Socket, not actually doing any processing when I tried to debug it, and I can reproduce this problem every time. I *know* I used to be able to debug these; anyone have any ideas what could be wrong now? thanks..
