zope2.Public from AccessControl isn't Public if used with grok.require

[Patrick Gerken]

Steps to reproduce:

1. Take any plone Project that has views defined with grok.
2. Change a require directive to "zope2.Public"
3. Try to access the view as a nonmanager
4. Confirm that you get an exception

There is a method checkPermission somewhere that handles the zope2.Public permission. But its never called.
The traverser instead just asks the Object and all it's parent which role has the required permission.

I can solve the issue by adding redefining the Public permission in AccessControl:AccessControl/permissions.zcml to include the role Anonymous.

But I am not sure whether this is the right way of fixing it. Therefor I'll create a branch and link it here afterwards

If there are no objections I'd like to merge change into trunk and 2.13 branch.

The change looks good once you add a changelog entry referencing this ticket. There's little point in the branch, as you already committed to trunk.

Wait, I did what to the trunk? http://imgur.com/ZkuH3

Changelog entries added, fix backported to 2.13 branch of AccessControl.

Thanks for your quick reaction!
