Both solution appear a bit "heavy" to me. I solved this issue for
TextIndexNG3 by adding generic support for wrapped objects by introducing an
IObjectWrapper interface which is checked by the indexer. Using
five:implements it is easy to attach this interface - if necessary - to any
wrapper class (including [EMAIL PROTECTED]). Writing an adapter
for adapting IndexableObjectWrapper to IObjectWrapper is trivial. I think
this solution is more straight forward and does not require any changes
to the CMF.

1. I think for the long term, IndexableObjectWrapper could be made a
decorator. This works as follows:
from zope.proxy import getProxiedObject
from zope.app.decorator import Decorator
class IndexableObjectWrapper(Decorator):
def allowedRolesAndUsers(self):
ob = getProxiedObject(self)
allowed = {}
for r in rolesForPermissionOn(View, ob):
allowed[r] = 1
localroles = _mergedLocalRoles(ob)
for user, roles in localroles.items():
for role in roles:
if allowed.has_key(role):
allowed['user:' + user] = 1
if allowed.has_key('Owner'):
del allowed['Owner']
return list(allowed.keys())
2. In the short term we can apply the following trick
(IndexableObjectWrapper needs to be a new style class!):
from zope.interface import providedBy
from zope.interface.declarations import ObjectSpecificationDescriptor
from zope.interface.declarations import getObjectSpecification
from zope.interface.declarations import ObjectSpecification
class IndexableObjectSpecification(ObjectSpecificationDescriptor):
def __get__(self, inst, cls=None):
if inst is None:
return getObjectSpecification(cls)
else:
provided = providedBy(inst.__ob)
cls = type(inst)
return ObjectSpecification(provided, cls)
class IndexableObjectWrapper(object): # new-style!
implements(...) # it can implement as much as it wants
__providedBy__ = IndexableObjectSpecification()
