Squeak 5 will run on Rasberry Pi OOTB

I managed to successfully incorporate the ARM platform into the 5.0
All-In-One -- so Squeak 5 will now start up with one-click on FOUR platforms, OOTB..!! I'm thankful to this community for collaborating to produce and shake out the 4.6 release. As this is a special dual release, your help is needed one more time to help shake out this 5.0 release. Would you please download this latest Squeak-5.0-All-in-One and check it out? We still have a chance to avoid obvious bugs, but we want to keep it as close to the 4.6 release as possible. http://ftp.squeak.org/5.0/Squeak-5.0-All-in-One.zip Here are some things I've noticed already, but I need your help to figure out how to deal with them: - someone said the VM is crashing in the Jenkins build due to ImageSegments tests. Do we want to disable those tests? - Actually, when I ran the tests in the image, there was no VM crash, but the dialog, "Running all tests might take a some minutes" (<--- hey that's some nice grammar there Marcel! ;-) ) appeared TWICE. When I clicked "Yes" the first time they ran, "Yes" a second time, no effect. Just a strange UI bug..? - Look at the image size, its DOUBLE the size of the 4.6 image. Why? I'm getting excited, thank you!! Chris |

In running the tests in the image, I also noticed this appeared on the console:

Excellent - one tiny change needs to be made to let it work on a Pi2 though; the shell script test for ARMv6l, which is correct for PiA+, B * B+ but the Pi2 is ARMv7. With that changed it fired up on my pi2 ok. > > > > - Look at the image size, its DOUBLE the size of the 4.6 image. Why? Space analysis on my Pi2 shows a lot of MC* objects, which as we’ve seen before seem to hold onto a lot of the 4Mb of String and quite a few arrays, symbols etc listed. Oh, and I noticed in the Contents/Resources directory that there seems to be a spare _test.[image|changes] pair.

Hey, great!
downloaded it on the Pi A+ installed my trusty 24/7 cat surveillance app and it worked. CPU usage went down from 50 to 40%. It exercises BitBlt, Collections, file I/O incl. GPIO, OSProcess and CommandShell Memory went up from 52M to 75M which is critical as I use the PiNoir Camera. I'll watch what comes out of Tim's (Rowledge) recent post. And I'll watch if it runs as stable as 4.5.

Dang; the 3410 Pi vm segfaults somewhere in StandardSourceFileArrayTest but the slightly older 3402 vm I’m using with my Scratch work doesn’t. Both with the all-in-one image of course.

Well the base image is about 20M bigger than the base 4.5 one for some reason, so that explains most of it.

Hi,
speedup depends on what is exercised. See my previous post. I get about 20% in my app which I'll gladly use for a higher framerate but I don't consider that dramatic. My first priority is stability. Then I'll check which parts of the program account for the improvements.

Hi,
I noticed some glitches: When I use list filtering for the instvars in an inspector the list doesn't automatically return to normal. Maybe a preference I missed. When I play with that list filtering at some point the CPU goes up to 90% and does not return until I shut down the image. The right click (personal) World menu has lost the entry to disable the main docking bar. I disabled it via preferences. Otherwise it survived the first hour :-)) Cheers, Herbert Am 23.07.2015 um 20:17 schrieb Herbert König: > Hey, great! > > downloaded it on the Pi A+ installed my trusty 24/7 cat surveillance > app and it worked. > CPU usage went down from 50 to 40%.

I think it's related to the segmented memory model of Spur, which uses
more memmory than the the compact model of pre-Spur Squeak. I think in Spur there should be a primivite which condenses all (non-pinned) segments, and minimizes their number. I'd probably be worth using such thing on "Save and Quit", because that way all pinned objects could be condensed too.

If you run the Space Analysis within the ‘About Squeak’ applet, it claims that the image has 300,000 objects taking up 25Mb . So somewhere there is 9Mb ‘wasted’ in some fashion. Since the tally code finds object sizes via a primitive that takes into account header sizes it should be adding up ok. There *is* code that avoids writing free space in each of the segments when snapshotting, as well as doing a garbage collect. So all in all, I’m puzzled where the space comes from. Run it under sim I guess and find out... tim -- tim Rowledge; [hidden email]; http://www.rowledge.org/tim Loyalty oaths.Secret searches.No-fly lists.Detention without legal recourse.

It appears I may have had my .prefs file loaded when I ran
#prepareNewRelease, which sets many preferences but not all of them. The ones it doesn't set were left to my preference. I was surprised to notice my scratch pad preference was on, it shouldn't be for the release (actually it should! but I won't go there.. :) ). I'll have to fix this... somehow. Now we know why Bert wants to support Preferences outOfTheBox. The one use-case we're missing is, we need to be able to _generate_ a #defaultValueTableForCurrentRelease from current preference settings..

I'm adding it. What I’m a bit puzzled about is that I have now tried out an assortment of MC reduction stuff - MCFileBasedRepository flushAllCaches. MCDefinition clearInstances. MCWorkingCopy stubAllAncestryForScratchRelease. MCWorkingCopy allManagers do: [:wc | wc unregister]. Project allSubInstancesDo:[:pr| pr resourceManager reset]. for example and it isn’t making any change to the image size at all so far as I can tell. I’ve even whacked the stubAncestry to to cut back to a single stub instead of 10 and no effect can be seen. Sumfing not right here... > >> Oh, and I noticed in the Contents/Resources directory that there seems to be a spare _test.[image|changes] pair. Presumably not actually wanted? > > Oops..
