Squeak 5.1, saving of Morphic projects is broken
Locked
 
|
Hello, Project saving is broken. When trying to save Morphic project to disk on 64bit image on Windows user is locked in the loop of popping up emergency evaluator, you have to kill Squeak as a OS process. See the docking bar, the second menu item is the Project menu. We need to add this to the known Issues session of the 5.1 release notes at least. This bug was pushed with Environments package since 4.5. Is anyone uses Environments? Can they be removed? Why Environments is not loadable package? regards, Vaidotas |

Hi Vaidotas,
according to the end of http://wiki.squeak.org/squeak/6218 this is now a VM problem. The image side shold have been solved. From older discussions I remember that environments are too deeply entangled with the guts of Squeak that it's not feasible to remove them again. And then some people may use them.

Hello Vaidotas
It can confirm that Project saving worked again in Squeak 4.6 in December 2015 with the fixes applied done by Colin Putney[1]. I did some tests then. The 64bit image is experimental. I just tested Project saving in Squeak 5.1 (32bit image) in MSWindows and on Linux. It does not work either. So we need to wait for a VM update. Regards Hannes [1] http://wiki.squeak.org/squeak/6218 <citation> With these four changes, it's possible to save and load projects in a Squeak 4.6 image. It doesn't work in a trunk image, however. The Spur VM crashes when saving a project. I've reported that on the VM list. It also fails to load an image segment - looks like the primitive for that isn't quite finished in Spur. </citation> On 8/26/16, Herbert König <[hidden email]> wrote: > Hi Vaidotas, > > according to the end of > http://wiki.squeak.org/squeak/6218 > this is now a VM problem.

Hi Hannes,
any tips how to get at that image and what VM to use? I still use 4.4 for development and later versions just for deployment. Thanks, Herbert Am Fri, 26 Aug 2016 13:16:03 +0100 schrieb "H.

Hallo Herbert
I am currently using the 5.1 release for development. I think it was 4 fixes in the Inbox and I just filed them in an Squeak 4.6 image (updated from the Squeak 4.6 all-in-one-release) in December 2015 http://forum.world.st/The-Trunk-System-cwp-781-mcz-td4864083.html http://forum.world.st/The-Trunk-System-cwp-782-mcz-td4864086.html http://forum.world.st/The-Inbox-Morphic-cwp-1055-mcz-td4864087.html http://forum.world.st/The-Inbox-Morphic-jmg-1055-mcz-td4864091.html It this is not sufficient give me some time to dig out that 4.6 image from the archive and try to recover what I did. --Hannes On 8/26/16, Herbert König <[hidden email]> wrote: > Hi Hannes, > > any tips how to get at that image and what VM to use?

Thanks Hannes,
I'll let you know. A typical image of mine contains lots of projects with documentation and ideas I need to be able to save. Cheers, Herbert Am Fri, 26 Aug 2016 13:43:06 +0100 schrieb "H.

Hi, in the process of updating Squeakland etoys to load in 5.1,we have also made the sexp format project saving and loading work again. This might be a VM independent way forward for storing projects. Regarding loading old projects, Bert has an experimental OldSegmentLoader that can load pre-Spur segments into 5.1 best, Herbert König <[hidden email]> schrieb am Fr., 26.

IMHO we should reconsider how project saving works. ImageSegments were a good technology back when machines and the interpreter VM was slow. Now we have faster machines and VMs so this very VM-dependent mechanism is no needed anymore. Yoshiki's S-Expression format is one way to serialize, yes. We have used it for the QuickGuide projects in the Squeakland image. In the short term it's a good option. However, for more general project saving we may want to take a look at other serialization schemes. I think we should deprecate ImageSegment. Is there any active use of them? I seem to remember SqueakMap used them but I'm not sure. - Bert - On Sat, Aug 27, 2016 at 3:07 PM, Tim Felgentreff <[hidden email]> wrote:

I seem to remember SqueakMap used them but I'm not sure. The last use *I* had for them was for exobox (so…. 1999? Were we partying? Ah, no, my archives say 2000 so we had given up on raspberry berets and indeed were shortly to give up on exobox) to load fonts very fast. It was indeed *very* fast compared to reading them any other way. However, I also have an email from Andreas of 5sep02 where we were discussing ‘script squeak’ and he asserts that some measurements convinced him that what he described as a ‘bytecode loader’ was faster, in part because of no pre & post ImSeg messing around. I have no idea if this is a profound thought or a trivia that everybody knows, but the deep-copy code seems awfully like (much of) a serialiser tim -- tim Rowledge; [hidden email]; http://www.rowledge.org/tim Useful Latin Phrases:- Noli me vocare, ego te vocabo = Don't call me, I'll call you. |
