... None should never be passed for attribute accesses. If it is, then there is a bug. The case of dictionary mapping names to whatever is for attribute access. We are talking about item/key access. I haven't seen a use case for needing to specify separate access for separate key values.
The original problem report (at least the one I read in this mailing list) was that a function registered with "setDefaultAccess" was called with "None" as "name" argument.
I expect that such a function is not called for dictionary or list access
but only for access to (class) instances.
When it is called, the name is relevant, as usually the name
will be used to distinquish which attributes should be accessible
and which not.
Well, the proginal message in this thread refers to an item access.
*************** *** 312,318 **** # Skip directly to item access o = object[name] # Check access to the item. ! if not validate(object, object, name, o): raise Unauthorized, name object = o continue
The code above this:
if not name or name == '_':
Checks for empty names or names beginning with underscrores, neither of which are legal attribite names.
So, this does seem to be about item access.
