Also zope.app.testing (which pulls in a ton of stuff)

And when I run the buildout I also get grok and such. The buildout 
contains old-style grok instance recipes - I think we want to update 
these to the new ones.

I'm going to describe some of the process of analysis I go through here..

It's important to look at the state in SVN, in case versions that grok's 
KGS depend on are still lagging behind in the refactoring.

First zope.app.appsetup:

zope.app.appsetup.IDatabaseOpenedWithRootEvent is now


(you can see the BBB imports if you look at these)

getInformationFromEvent is also used from that package. Maybe there's a 
way to avoid it?

If not, we have do something else. We could move 
getInformationFromEvent. We could lift it up into grokui.admin, but we'd 
like to avoid that. Plus it also depends on something from 
zope.app.publication. An alternative is to move it into 
zope.app.publication then. That would also allow us to break up dependency.

Perhaps zope.app.publication is something we can't break the link with 
that easily in general with Grok (though grokui.admin should ideally 
still break it..). In this case we should break the dependencies of 
zope.app.publication. The main dependencies of this package are already 
okay, but it still has tons of test dependencies which we should try to 
break by working on the tests of zope.app.publication to try to break 

Now zope.app.applicationcontrol

IServerControl is an interface. Don't see a quick way to get rid of it.

You shouldn't be using the RuntimeInfoView directly in grokui.admin. You 
should use the IRuntimeInfo adapter directly. Not that this breaks the 
dependency on zope.app.applicationcontrol, but it will make it easier to 
do so in the future. Same with ZODBControlView. Can you take care of 
that in grokui.admin?

I'll look at extracting some of this stuff from 
zope.app.applicationcontrol into something more reusable.
