Some images share some code (classes, compiledMethods) But what about code mutations/updates? Without such mutations, is it still Smalltalk? Without active imprinting, such mutations might not be obvious to propagate (for example a subclass now overrides a message of super) And since you import class builder and compiler in the target, on what purpose? Is the target going to change a class locally? What if it then imports incompatible methods from provider? Or is the goal to just replicate some mutations from the provider? Maybe the scheme is more interesting for deployment of static code, but I'm curious to know if ever live updates would still be possible... > thanks, > > -C > > -- > Craig Latta > netjam.org > +31 6 2757 7177 (SMS ok) > + 1 415 287 3547 (no SMS) > > >

What code would you like to see imprinted? > Test suites. To me, the holy-grail of deployment scaling is I first I develop and configure in a big luxurious Cadillac image loaded with tools until I'm ready to deploy. When I'm ready to deplooy I fire up a copy of your 1MB core image as the "target" with my luxury image as the 'source' and then I simply bring over a top-level test-suite method into the target and run it. As the methods are executed and found to be missing in the 1MB target, they are brought over from the source. By the time the tests are done, /all/ and /only/ the methods which were needed to run the tests were brought over by Spoon / Naiad. Now I want to save that target image (maybe 5MB now) and deploy it. I will want to run many multiple copies of of that 5MB image but since my tests probably don't have 100% coverage it would be too risky to run in production unless each of those 5MB images could have backup Spoon access to a single running copy of my mother Caddi' image, in case one more method is found to be needed... So I see Spoon as a way for learning about systems like you, but also as a solution for scaling -- from the smallest single core for limited hardware <---> to the largest multi-core, applications because one can run MORE images concurrently due to their smaller size. > In any case, I do plan to make videos showing all the top-level > features. > > > thanks, > > -C > > -- > Craig Latta > netjam.org > +31 6 2757 7177 (SMS ok) > + 1 415 287 3547 (no SMS) > > >

That sounds awesome Craig, congratulations. If you ever do a video of a reasonably-sized imprinting experiment onto your core-classes image from a modern Squeak image, I will be very interested to see it!
