I use a single Zope instance for several small CMF sites and I use .zexp
export and import for moving CMF sites from one Zope instance to an
other. Works fine for me. Even with Plone sites.
Even if it works for you I'm not sure that this is a use case we should
support.
The nastiest part of the bootstrapping issue is the fact that without
the fallbacks currently in place you can't navigate to the Setup Tool of
a CMF 2.2 instance and run the upgrades. The ZMI folder listing calls
code that depends on CMF tools.
But fixing these issues is not on the top of my list. I just mentioned
them for the sake of completeness.
Which is fine and something we don't do often enough!
2.) Site root lookup: =====================
In several tools we still assume aq_parent(aq_inner(self)) is the
portal. Or other code uses the tool as context object, expecting root
and request in its acquisition chain.
These should be identified and replaced by
getUtility(IURLTool).getPortalObject() or other suitable code.
Maybe we could add a convenience API for that?
getToolByName can be used instead as it does the lookups.
getToolByName is no option because it is part of the machinery that
should become obsolete.
Not sure that is should actually ever become obsolete. Much as I am in
favour of the interface-based lookup, these tools are an essential part of
the CMF.
getUtility(IURLTool).getPortalObject() might be overkill because it
adds the request to the context. All the code that needs the request
should be fixed already. Using queryUtility(ISiteRoot) should be
sufficient.
But AFAICS the only way to find all the places where this needs to be
fixed is to set up a site with tools that are not stored in the site
root.
That's a big ask.
