[Zope3-dev] IPrincipalPermissionMap: diff between interfaces and usage

[Garanin Michael]

Hello!

1) In "zope/app/securitypolicy/interfaces.py"  method "getSetting" get
only 2 parameters:
-------------------------------------------
   IPrincipalPermissionMap ....
      def getSetting(permission_id, principal_id):
    ....	   
-------------------------------------------

2) But in 'zopepolicy.py' method 'getSetting' always call with 3
parameters:
---------------------------------------------
prinper = IPrincipalPermissionMap(parent, None)
prinper.getSetting(permission, principal, None)
.....

-----------------------------------------------


is it bug in "zope/app/securitypolicy/interfaces.py"?
