Re: [Pharo-project] What is correct way to save image automatically in background?

by Denis Kudriashov

Sorry for not correct thread title. I dont need save image in background while all system continue work. I just want save image from my smalltalk process. And when I do this I sometimes cant restart image (it crash due to some world cycle activity and freetype plugin failure). But when I save image manually I never see that situation. Maybe somebody know why this happen? And how I must save image from some smalltalk process correctly? 2010/7/23 Lukas Renggli <renggli(a)gmail.com> > > But How I can do that without fork?

Now I don't know what is the state of affaire regarding enabling/unenabling sounds from the Setting browser. It looks like the sound option in the Setting browser has not action. It looks like a specific Process is used to play sound, right? SoundPLayer initialize. Should we add a setting in the preference for that purpose?

I have also applied the changes to sound from the Squeak friends.

I don't understand what you are saying. The thing is that using #fork to save the image has no effect (other than wrecking the image), because #snapshot:andQuit: is eventually calling a primitive that locks the complete VM anyway. If you want to fork while saving the image you need to use an OS-level fork, not a Smalltalk-level fork. You can do this with OSProcess for example (check the Seaside mailing-list archive).

But How I can do that without fork? I track changes in another process and when I do update I save image in this process. How I can initiate image saving from ui process? 2010/7/23 Lukas Renggli <renggli(a)gmail.com> > > What is correct way to save image for my purpose? > > Don't fork. > > Lukas > > -- > Lukas Renggli > www.lukas-renggli.ch > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project >

[Pharo-project] What is correct way to save image automatically in background?

by Denis Kudriashov

In my app I need update pharo image with some resources (new package, icons, configs...) remotelly. After updating I need save image session. For that app show user some special screen, save image and return to ussual app state. My app has process that do system changes when needed and "commit" it as I wrote. I do something like [self blockUI. self doUpdate. SmalltalkImage current snapshot: true andQuit: false. self unblockUI. ] fork And sometimes after image restart I have image crash due to some world cicle activity and freetype plugin failure. I try little [SmalltalkImage current snapshot: true andQuit: false] fork code from workspace. And situation same - sometimes image cant restart. I never see that when I save image manually. What is correct way to save image for my purpose?
