Squeak dies while debugging
by Damian Dobroczyński 04 Jun '07

04 Jun '07

I've been playing around with Squeak and noticed that if I try to debug an expression (highlighting it in a workspace and clicking "debug it" in menu") i'll end up freezing the whole system. This happens when I keep clicking on "Into" button in debugger so that the last message sent is: Process>>terminate: "..." self primitiveSuspend Is this normal to Squeak users interrupt debugging before it reaches the very bottom of the calling stack before the whole system silently dies? Is it possible for Squeak just to leave the debugger silently when it should leave? Damian

From: Michael van der Gulik <mikevdg(a)gulik.co.nz> Subject: Re: [Newbies] squeak on ubuntu linux Hi Michael. Thank you for your reply so far... >>I would recommend trying the 64-bit binaries: >>http://www.squeakvm.org/squeak64/. I have used this version of Squeak on an AMD-64 machine without any problems. This site has Squeak3.8g-6548... I understand that our 3.9, 32bit, image should not run under this squeak anyway? We did try that build. I can't remember the errors we've got; but it didn't work. We could try it again and report the errors if need be.. Kind regards, Liliana

squeak on ubuntu linux
by Liliana 04 Jun '07

Hi, We have an Intel dual core 64 bit server where we installed Ubuntu 7.04 We are all new in Squeak/Smalltalk; but we managed to develop a small Seaside app in Squeak (on Windows XP) using Squeak 3.9 and Seaside 2.7 (latest). We would now like to install this image on the linux server and run seaside there, under Apache. I read quite a few of posts and Ramon Leon's blog on how to get a squeak/seaside headless vm working on Linux; but we are all but confused; and didn't manage to get anywhere. Questions: 1. Do we need x-windows, or not (we will not do development on the linux server)? 2. Is there a squeak vm we can download or do we have to build from source for Intel dual-core? ( we tried both versions and neither works) The debian packages at: http://ftp.squeak.org/debian/ stable main don't seem to work for linux running on intel dual core and we downloaded Squeak-3.9-8.i686-pc-linux-gnu.tar.tar from http://www.squeakvm.org/unix/ With this last one installed we get the error: "could not find module vm-display-X11" When we run: squeak -headless groupinvestment.image (where groupinvestment.image is our Windows build image containing seaside and our web site) And when we run: squeak -nodisplay groupinvestment.image we get: Segmentation fault 45396408 SmalltalkImage>snapshot:andQuit:embedded: 45396316 SmalltalkImage>snapshot:andQuit: 45396224 SmalltalkImage>saveSession 45396040 TheWorldMenu>doMenuItem:with: 45395948 [] in MenuItemMorph>invokeWithEvent: 45395856 BlockContext>ensure: 45395764 Cursor>showWhile: 45395552 MenuItemMorph>invokeWithEvent: 45395460 MenuItemMorph>mouseUp: 45395368 MenuItemMorph>handleMouseUp: 45395236 MouseButtonEvent>sentTo: 45395144 Morph>handleEvent: 45395052 MorphicEventDispatcher>dispatchDefault:with: 45394960 MorphicEventDispatcher>dispatchEvent:with: 45394868 Morph>processEvent:using: 45394776 MorphicEventDispatcher>dispatchDefault:with: 45394668 MorphicEventDispatcher>dispatchEvent:with: 45394536 Morph>processEvent:using: 45394444 Morph>processEvent: 45394352 MenuMorph>handleFocusEvent: 45394076 [] in HandMorph>sendFocusEvent:to:clear: 45394168 [] in PasteUpMorph>becomeActiveDuring: 45393984 BlockContext>on:do: 45393892 PasteUpMorph>becomeActiveDuring: 45393708 HandMorph>sendFocusEvent:to:clear: 45393616 HandMorph>sendEvent:focus:clear: 45393524 HandMorph>sendMouseEvent: 45393380 HandMorph>handleEvent: 45393072 HandMorph>processEvents 45393164 [] in WorldState>doOneCycleNowFor: 45392980 SequenceableCollection>do: 45392888 WorldState>handsDo: 45392796 WorldState>doOneCycleNowFor: 45392704 WorldState>doOneCycleFor: 45392612 PasteUpMorph>doOneCycle 34840512 [] in >spawnNewProcess 34840696 [] in BlockContext>newProcess Aborted Thank you for any help you could give us Liliana Ivan liliana(a)finwork.biz 012 663 3140 Finworks <http://www.finworks.biz/>

"Callback" design pattern
by Stephen Davies 03 Jun '07

03 Jun '07

Hi, I've been busy with hooking Squeak to Asterisk via the Asterisk FastAGI protocol. I also want to write code to talk to the Asterisk Manager Interface. In both cases I need to write an interface to allow others to "register" to hande particular AGI call, or to "register" to hear about particular AMI events. I suppose the method of callback will boil down to "call method #whatever on object anObject", or maybe you could register a block to be evaluated. Now I'm sure there must be an established way to do this in Squeak and I'd like to use it. Or at least code mine in the "usual style". So could someone point me at some classes in the system that I should look at? Thanks, Steve
