[Zope3-Users] zope.app.component.tests.test_site.py doctests failing

[Sven Schomaker]

Hello all,

I tried to get in to the revised site manager stuff but I didn't
manage to get it up running. I started out with a simple local
utility registration:

from persistent import Persistent
from zope.app import zapi
from zope.app.tests import setup
from zope.interface import Interface, implements
from zope.app.container.contained import Contained
from zope.app.component.site import LocalSiteManager
from zope.app.workflow.tests.workflowsetup import WorkflowSetup
from zope.app.component.site import UtilityRegistration
from zope.app.component.interfaces import ILocalUtility
from zope.app.component.interfaces.registration import ActiveStatus

class ITestUtility(Interface):
    """
    Test utility interface.
    """
    pass   

class TestUtility(Contained, Persistent):
    implements(ITestUtility, ILocalUtility)

wfs = WorkflowSetup()
wfs.setUp()

folder2_1 = zapi.traverse(
    zapi.getRoot(wfs.sm),
    "/folder2/folder2_1")

sm = LocalSiteManager(folder2_1)
folder2_1.setSiteManager(sm)

sm = folder2_1.getSiteManager()
sm_folder = sm['default']
sm_folder['test1.0'] = TestUtility()
       
rm = sm_folder.registrationManager
rg = UtilityRegistration('test1.0',
    sm_folder['test1.0'], rm)
       
rm.addRegistration(rg)
           
rg.status = ActiveStatus


sm.queryUtility(ITestUtility, 'test1.0')

The retrieval of the utility from the sm fails
giving the following stacktrace.


File "/usr/local/lib/python2.4/site-packages/zope/component/site.py", 
line 90, in queryUtility
    byname = self.utilities._null.get(interface)

Since I didn't know any better I checked out the tests located
in zope.app.component and they also fail giving the following
output:

FAILED (failures=1)

Is this a failure on my side or is there a problem with the trunk?
Checked out revision 29417 today. Compiled the z3 sources and executed the
test with Python 2.3.4 [GCC 3.3.4 (pre 3.3.5 20040809)].


Any Ideas?
