Hi all,
I have prepared the new version of the KernelImage. The most important new is the independence of the MinimalMorphic package. That means that MinimalMorphic package has no overrides now and we are be able to modify and publish Kernel and basic primitive packages directly from the MinimalMorphic image!
I have to say that some of the secessary refactorings are very ugly now but the main goal was to make the MinimalMorphic independent soon and enable to develop the kernel refactorings in more comfortable way.
The test and some other small packages were removed from the EToys package. The next step should be improvement and splitting of tests. The complete image has 20 failures and 3 errors now. The EToys package has still many overrides.
All packages should include 3.10 patches up to 7091.

I tried all four images on my Mac, with varying results. The VMs that I tried were 3.8.14Beta3U and 3.8.15Beta1U, and I got the same results with both of them.
I started up KernelImage and KernelImageMC and they both started up and gave me a promt. I did not test them further. I tried MinimalMorphic, and the image started up but never displayed anything. I couldn't do anything to make it display. I tried EToys and if I make sure that the SqueakV39.sources file is *missing* then it starts up with an error message that it can't find SqueakV39.sources, but then runs the image *without* refreshing the window. I can open browser, etc and then move them around to get the entire window painted, but until I do that, it is just black. However, if I leave the SqueakV39.sources file in the directory, it behaves like the MinimalMorphic image, i.e. it never displays any window at all.
Has anybody else with a Mac had better luck? Which VM did you use?

Hi Ralph,
even on the Linux VM some problems with display refreshing are present but aren't so deadly as in case of Mac VM. I'll try to look at it. Has someone any advice?

It works on win32 (browser, file list, transcript, workspace) with the 3.9.2 VM.
Except the scroolbars which are on the wrong side ;-)
Thank you Pavel.

Works somewhat with on my PPC iBook with one of Ian's VMs (3.9-7 #6). Browsing, file listing, world menu's do submenu, etc. all worked. But switching to the previous project resulted in an unresponsive image. Tried it directly and by choosing it from the 'jump to project...', logs attached.
Thanks for working on this.

Hi Steven,
thank you, it's the known issue. During Morphic initialization we create one temporary parent project. We have to delete it.

Hi Pavel,
Very good job!
I mainly used MinimalMorphic and the following micro-report is about it. I didn't any benchmarks (did you?) but it seems really fast which is great. But, the image file size difference compared to KernelImageMC is just too much (MinimalImage 2 times larger!). Do you plan to shrink minimal morphic further ?
Three bugs in MinimalImage:
-Exceptions don't understand defaultAction while this message is sent (at least) in UndefinedObject>>handleSignal:
-When entering or leaving a Morphic, I got an exception in LanguageEnvironment>>isFontAvailabe because TextStyle defaultFont don't understand fontArray.
-I tried to enter into an MVC project but failed. Squeak draws the MVC, but then I get an error in Project>>isTopProject and a restore display shows the root project. The parentProject IV of the MVC project is set to nil instead of refering to a Project.
BTW, the size difference between KernelImageMC and Noury Le 29 avr. 07 à 09:53, Pavel Krivanek a écrit :

Pavel, if there are changes you'd like made to 3.10 to make your life easier, or if you think that some of the changes you have made are ready to be put into 3.10, please let us know.
I think that KernelImage is the future of Squeak. it isn't ready yet to become the standard image, but it is getting close. Perhaps it should be the basis of 3.11.

I always wish go Kernel close or MinimalMorphic close. Also wish Pavel be part of the release team. So I do less and learn more :=)

I have published some changes on Mantis but I will try to check them again and start to push them systematically to make 3.10 closer to my images. In fact, it will not make my life easier ;-) but at least the changes will be seen by more eyes.

As earlier noted the mac carbon vm won't open a window until something schedules a (127 primitiveShowDisplayRect)
also if defer display updates was set (126 primitiveDeferDisplayUpdates)
then the window would't be opened because we've asked to defer screen updates.
If no one gets around to doing the proper prim call you won't get a window. Also since the call is of the form displayBitsOf: aForm Left: l Top: t Right: r Bottom: b likely you've noted you'll get a dialog box on a black screen because something has just asked to draw the dialog box, however nothing yet has asked to draw the entire screen.
A possible fix would be doing a fullDisplayUpdate early on in the image startup process, the downside is that on slow machine you'll get a window up that you cannot interact with until perhaps many seconds have passed.
In 3.8.17bx I altered this so that if you are using Ffenestri you can configure the VM not to open a window until you make the Ffenestri call to create a window.

In some cases I created more general class that contains "kernel" implementation. The Morphic then simply adds its override (now in the class hierarchy meaning) to the original class. Such example is the BasicChangeSet class.
Then I created methods like specificOperation1: in the Object interface. When the Kernel calls it, it does nothing. Morphic adds its implementation of this general method. It's about in 24 cases.
I hope that we will be able to replace it with better and more general refactorings soon.
