Re: Shrinking

Colin

at the start of this thread (6th January)
you said that you do

Smalltalk shrinkAndCleanDesktop

and later and after some fixes (to the image and/or the trunk?) you
report that the resulting image is below 10MB.

As of now is

Smalltalk shrinkAndCleanDesktop

all that I need to do or do I need to issue other commands?

I always wish Pavel work was taked into Squeak, but we have a champion
shrink image and is Cuis reduced.

You could have a 2 mb .image Morphic enabled.

No. I started with that, but it doesn't quite work, so I extracted it into a script. I've been tweaking the script to fix issues as they come up, and to customize the shrink to the needs of my project. I'm pushing generally useful fixes back into trunk, but it's not completely done yet.

I'm also finding that every time I update to a new trunk image from build.squeak.org, I run into new issues. :-)

I'm hoping that's a good thing :/ Chris & I replaced the base CI
image, by the way. So at least your starting point nowadays will have
clean packages (even if it's not semi-pre-slimmed). I'll take another
run at the the minimal-base-image-rehydrated-on-CI approach in the 4.6
cycle.

Ah, good idea. For 4.5, let's let the final deployment image to be
one which has never undergone a shrink / rehydration. If we want to
risk that for 4.6 release then put out our *second* 4.6 alpha image be
one of those rehydrated so it can endure a full release-cycle of
testing including under our personal projects.
