[Zope] Zope debugging, TmpStorage and other stuff

[Andrey V Khavryutchenko]

Hi!

To set up the debugging framework for my application, I have to do
something that would:
 - construct the Zope object with temporary storage w/o starting any
servers
 - build my site in this Zope object (trivial, not a problem)
 - pass requests to this Zope object

Here's the sketch code:

# -*- python -*-
# sketch, not the real code

import Zope, ZPublisher, ZODB
Zope.DB = ZODB.TmpStore.TmpStore(Zope.Globals.DatabaseVersion)

# at this point I want to have Zope ready to serve using the temporary
# storage and w/o binding any inet ports

import mysite
mysite.build(Zope.root_folder)

# here my site is constructed in previously build Zope object

print ZPublisher.publish(Zope.root_folder, '/index_html')

# this prints the main page of my site

# end of python code



Questions:

(1) Will the stuff like this work?  Would somebody, knowledgeable of Zope
internals, to advise:
 - how to change ZODB storage?
 - how to access Zope root folder?
 - how correctly run requests against Zope object?

(2) Rather stupid.  I can't import Zope:

  File "/usr/share/zope/lib/python/AccessControl/User.py", line 294, in ?
    raise 'InstallError', (
InstallError: No access file found at /usr/share/zope - see INSTALL.txt

Investigation shows that the problem is wrong content of INSTANCE_HOME, but 
I have some difficulties to figure out at midnight how to pass it into
AccessControl.User :)



Thanks in advance.
