Omnibrowser update for 4.5
by Jeff Gonis 07 Mar '14

07 Mar '14

Hi Folks, I was playing around with the release candidate image and testing out some of the SqueakMap stuff and I wanted to test if the Omnibrowser still works. I ran into a debugger related to the timeStamp method Frank removed from CompiledMethod early last year. I fixed it and the omnibrowser seemed to work and so I was going to contribute this fix when I saw that a ton of work has been done to the Omnibrowser since it last loaded into Squeak in 4.2, including fixing this issue. Colin do you know if this work is up and running on the Squeak image, and are you able to push an updated Metacello configuration to SqueakMap? Do I have the ability to do this, and would you like me to take some of this load off of your shoulders if that access is available? Anyway, the image is looking great otherwise and I just wanted to throw this out onto the list as the Omnibrowser is a great tool. Thanks for your time, Jeff

Cog using virtual memory under Linux
by Herbert König 06 Mar '14

06 Mar '14

Hi, I run a Squeak image under Cog on a hosted virtual Linux server. Croquet Closure Cog VM [CoInterpreter VMMaker.oscog-eem.201] Unix built on Aug 14 2012 09:25:00 Compiler: 4.1.2 20080704 (Red Hat 4.1.2-48) platform sources revision VM: r2585 Lately I used it for some optimizations running for several days and the Hoster complained that I create too much IO, my CPU usage being no problem. I have no idea how I could create IO but it occurs during my CPU usage. I do no IO I know of. Only idea I have is accessing virtual memory. Changes file is 37MB and not growing during the computations. TOP tells me the image is actually using 60 MB but virtual memory is 1GB. VM statistics reports 50 MB, 40 MB used. The virtual server has 512 MB, 200MB free. Nothing else runs on the machine. The server has no X running I operate Squeak through Tight VNC tunnelled through SSH. Is it possible that Cog frequently tries to access virtual memory under these circumstances? The system does not slow down compared to the same calculations on my Windows laptop where I have sufficient memory. Any ideas of other ways I might involuntarily create the IO load? Thanks, Herbert

Hi Raymond, we decided to try releasing with a clean look this time. The problem I have with the welcome workspaces is that they're insufficient (even misleadingly so) for guiding new users into productivity with Squeak, and yet annoying enough for users who want to drive on their own. Most other applications don't pop up welcome messages (maybe some, but not most), but I think its safe to say "most" put information about themselves under Help | About, which is where it can found in Squeak too.

Interrupt key idiocy
by tim Rowledge 06 Mar '14

06 Mar '14

Y’know what is still annoying the hell out of me when developing? The damn interrupt key stuff. I’ll leave aside the problem with not necessarily interrupting the ‘right’ process, because I know that is really quite difficult. But the spec we agreed something like a decade (or more) ago was that the interrupt key combo, when pressed, would NOT be passed into the image but would immediately trigger the relevant semaphore. That should open a debugger pretty lickety-split. It doesn’t seem to work that way any more, with frequent cases where nothing happens for a very long time, often long enough that you simply give up and force-quit. I *think* this is often in a deep recursion scenario, which I understand can be a problem for collecting all the contexts. I know it worked very well on RISC OS. It doesn’t appear to be doing very well on OS X nor linux/Pi. So, I have to admit I’m a bit puzzled to see image code (in EventSensor>processEvent:) that purports to handle the interrupt key code that is supposed never to get there. The comment in the related code in InputSensor>primInterruptSemaphore: explicitly refers to the setting of the semaphore for the VM as obsolete, though it does at least actually set it. So far as I can see the prim exists and does the right thing. The only material difference I can find between platforms is that RISC OS does setInterruptPending(true); forceInterruptCheck(); whereas all others do just setInterruptPending(true); and perhaps that makes a big difference. Event handling code in the relevant platform files also appears to explicitly *not* pass in a cmd-. key-press which confuses me further, since that makes it seem like the system is actually relying upon the semaphore being signalled by the VM despite the image code. Whatever the details really are, it would certainly be nice to make response to the interrupt key *really* fast. tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Never do at compile-time what you can put off till run-time

All-In-One updated with Mac VM
by Chris Muller 06 Mar '14

06 Mar '14

I'm not sure where we left off in the other thread -- I don't want to jump ahead of Tobias or Glen, but just in case I went ahead and uploaded a new All-In-One http://ftp.squeak.org/4.5/Squeak-4.5-All-in-One.zip which replaces the Mac VM with Eliots latest. Where .bundle directories existed in the old and new, I first removed the entire old before copying in Eliots (so it wouldn't "merge" those directories). Eliot said the extra plugins from the prior VM should work as-is. The only two files left intact from the old VM are: ./Contents/MacOS/Squeak VM Opt ./Contents/MacOS/Squeak VM Opt.sig but these might be the ones we replace when we sign it. Craig has volunteered to do this but maybe a Mac owner should at least give it a whirl first really quick. - Chris

Spoon 3 beta 5
by Craig Latta 05 Mar '14

05 Mar '14

(repost, link edited) Hi-- Spoon 3 beta 5 is released[1]. I’ve still got a bunch of changes pending, for a 3b6 release to follow shortly. This release is just to fix some startup problems on Windows, Linux, and Mac OS. You can also find the Spoon VM changes separated out, in the second “Resources” folder. What I’d like is for you to just start the Spoon app and tell me the results, along with your host platform. Followups to comp.lang.smalltalk.squeak.spoon, please. Thanks! -C [1] http://thiscontext.com/2014/03/04/spoon-3-beta-5-released -- Craig Latta www.netjam.org/resume +31 6 2757 7177 (SMS ok) + 1 415 287 3547 (no SMS) -- -- Craig Latta www.netjam.org/resume +31 6 2757 7177 (SMS ok) + 1 415 287 3547 (no SMS)
