... From a bit of digging through the code it seems there is a difference comes about in the call on line 166 of AccessControl.User inside _check_context :
return object.aq_inContextOf(context, 1)
In Zope 2.8 it returns 0, in 2.76 it returns 1
Looks like an acquisition bug: obj.aq_inContextOf(context, 1) is recursively defined by: True, if "obj.aq_base == context.aq_base" or "container(obj) is not None" and "container(obj).aq_inContextOf(context, 1)" where "container(obj)" is "aq_parent(aq_inner(obj))" which is the container containing "obj". which is equivalent to (resolving the recursing): obj.aq_inContextOf(context, 1) iff for some (hierarchie) ancestor "a" of obj, "a.aq_base == context.aq_base". Given this definition, you can check which implementation is wrong and file a bug report. -- Dieter
