2.13.14 (2015-12-21)
--------------------
- Avoid acquiring ``access`` from module wrapped by
``SecurityInfo._ModuleSecurityInfo``. See:
https://github.com/zopefoundation/AccessControl/issues/12
2.13.13 (2013-07-16)
--------------------
- LP #1169923: ensure initialization of shared ``ImplPython`` state
(used by ``ImplC``) when using the "C" security policy. Thanks to
Arnaud Fontaine for the patch.
2.13.12 (2012-10-31)
--------------------
- LP #1071067: Use a stronger random number generator and a constant time
comparison function.
2.13.11 (2012-10-21)
--------------------
- LP #966101: Recognize special ``zope2.Private`` permission in ZCML
role directive.
2.13.10 (2012-09-09)
--------------------
- LP #1047318: Tighten import restrictions for restricted code.
2.13.9 (2012-08-23)
-------------------
- Fix a bug in ZopeSecurityPolicy.py. Global variable ``rolesForPermissionOn``
could be overridden if ``__role__`` had custom ``rolesForPermissionOn``.
2.13.8 (2012-06-22)
-------------------
- Add Anonymous as a default role for Public permission.
2.13.7 (2011-12-12)
-------------------
- Exclude compiled ``.so`` and ``.dll`` files from source distributions.
2.13.6 (2011-12-12)
-------------------
- Added ``manifest.in`` to ensure the inclusion of the ``include`` directory
into the release.
2.13.5 (2011-12-12)
-------------------
- Apply changes made available in ``Products.Zope_Hotfix_20111024`` and make
them more robust.
2.13.4 (2011-01-11)
-------------------
- Return the created user in ``_doAddUser``.
- Added ``IUser`` interface.
- LP #659968: Added support for ``level`` argument to the ``__import__``
function as introduced in Python 2.5. Currently only ``level = -1`` is
supported.
2.13.3 (2010-08-28)
-------------------
- Added a ``role`` subdirective for the ``permission`` ZCML directive. If any
roles are specified, they will override the default set of default roles
(Manager).
2.13.2 (2010-07-16)
-------------------
- Added ``override_existing_protection`` parameter to the protectName helper.
2.13.1 (2010-06-19)
-------------------
- Restore security declarations for deprecated ``sets`` module.
2.13.0 (2010-06-19)
-------------------
- Released as separate package.

Extension Class Definitions
Implementing base extension classes
A base extension class is implemented in much the same way that an
extension type is implemented, except:
- The include file, 'ExtensionClass.h', must be included.
- The type structure is declared to be of type
'PyExtensionClass', rather than of type 'PyTypeObject'.
- The type structure has an additional member that must be defined
after the documentation string. This extra member is a method chain
('PyMethodChain') containing a linked list of method definition
('PyMethodDef') lists. Method chains can be used to implement
method inheritance in C. Most extensions don't use method chains,
but simply define method lists, which are null-terminated arrays
of method definitions. A macro, 'METHOD_CHAIN' is defined in
'ExtensionClass.h' that converts a method list to a method chain.
(See the example below.)
- Module functions that create new instances must be replaced by an
'__init__' method that initializes, but does not create storage for
instances.
- The extension class must be initialized and exported to the module
with::
PyExtensionClass_Export(d,"name",type);
where 'name' is the module name and 'type' is the extension class
type object.
Attribute lookup
Attribute lookup is performed by calling the base extension class
'getattr' operation for the base extension class that includes C
data, or for the first base extension class, if none of the base
extension classes include C data. 'ExtensionClass.h' defines a
macro 'Py_FindAttrString' that can be used to find an object's
attributes that are stored in the object's instance dictionary or
in the object's class or base classes::
v = Py_FindAttrString(self,name);
In addition, a macro is provided that replaces 'Py_FindMethod'
calls with logic to perform the same sort of lookup that is
provided by 'Py_FindAttrString'.
Linking
The extension class mechanism was designed to be useful with
dynamically linked extension modules. Modules that implement
extension classes do not have to be linked against an extension
class library. The macro 'PyExtensionClass_Export' imports the
'ExtensionClass' module and uses objects imported from this module
to initialize an extension class with necessary behavior.

Security Architecture
---------------------
Users
-----
Objects representing users may be created in Principia
User Folder objects. User objects maintain the information
used to authenticate users, and allow roles to be associated
with a user.
Permissions
-----------
A "permission" is the smallest unit of access to an object,
roughly equivalent to the atomic permissions seen in NT:
R (Read), W(Write), X(Execute), etc. In Principia, a permission
usually describes a fine-grained logical operation on an object,
such as "View Management Screens", "Add Properties", etc.
Different types of objects will define different permissions
as appropriate for the object.
Types of access
---------------
A "type of access" is a named grouping of 0 or more of the
permissions defined by an object. All objects have one predefined
type of access called Full Access (all permissions defined by that
object). A user who has the special role "Manager" always has Full
Access to all objects at or below the level in the object hierarchy
at which the user is defined.
New types of access may be defined as combinations of the
various permissions defined by a given object. These new
types of access may be defined by the programmer, or by
users at runtime.
Roles
-----
A role is a name that ties users (authentication of identity)
to permissions (authorization for that identity) in the system.
Roles may be defined in any Folder (or Folderish) object in the
system. Sub folders can make use of roles defined higher in the
hierarchy. These roles can be assigned to users. All users,
including non-authenticated users have the built-in role of
"Anonymous".
Principia objects allow the association of defined roles
with a single "type of access" each, in the context of that
object. A single role is associated with one and only one
type of access in the context of a given object.
Examples
--------
User Object1
o has the role "RoleA" o has given "RoleA" Full Access
Result: the user has Full Access to Object1.
User Object2
o has the role "RoleA" o has given "RoleB" Full Access
o has given the role "RoleA" View Access,
a custom type of access that allows only
viewing of the object.
Result: the user has only View Access.
Notes
-----
All objects define a permission called "Default permission". If this
permission is given to a role, users with that role will be able to
access subobjects which do not explicitly restrict access.
Technical
---------
Objects define their permissions as logical operations.
Programmers have to determine the appropriate operations
for their object type, and provide a mapping of permission
name to attribute names. It is important to note that permissions
cannot overlap - none of the attributes named in a permission
can occur in any of the other permissions. The following are
proposed permissions for some current principia objects:
Folder
o View management screens
o Change permissions
o Undo changes
o Add objects
o Delete objects
o Add properties
o Change properties
o Delete properties
o Default permission
Confera Topic
o View management screens
o Change permissions
o Undo changes
o Add objects
o Delete objects
o Add properties
o Change properties
o Delete properties
o Default permission
o Change Configuration
o Add Messages
o Change Messages
o Delete Messages
Tabula Collection
o View management screens
o Change permissions
o Undo changes
o Add objects
o Delete objects
o Add properties
o Change properties
o Delete properties
o Default permission
o Change schema
o Upload data
o Add computed fields
o Change computed fields
o Delete computed fields
Document/Image/File
o View management screens
o Change permissions
o Change/upload data
o View
Session
o View management screens
o Change permissions
o Change session config
o Join/leave session
o Save/discard session
Mail Host
o View management screens
o Change permissions
o Change configuration
To support the architecture, developers must derive an
object from the AccessControl.rolemanager.RoleManager mixin class,
and define in their class an __ac_permissions__ attribute.
This should be a tuple of tuples, where each tuple represents
a permission and contains a string permission name as its first
element and a list of attribute names as its second element.
Example:
__ac_permissions__=(
('View management screens',
['manage','manage_menu','manage_main','manage_copyright',
'manage_tabs','manage_propertiesForm','manage_UndoForm']),
('Undo changes', ['manage_undo_transactions']),
('Change permissions', ['manage_access']),
('Add objects', ['manage_addObject']),
('Delete objects', ['manage_delObjects']),
('Add properties', ['manage_addProperty']),
('Change properties', ['manage_editProperties']),
('Delete properties', ['manage_delProperties']),
('Default permission', ['']),
)
The developer may also predefine useful types of access, by
specifying an __ac_types__ attribute. This should be a tuple of
tuples, where each tuple represents a type of access and contains
a string name as its first element and a list of permission names
as its second element.
By default, only "Full Access" is defined (by the RoleManager mixin).
If you wish to override __ac_types__ to provide convenient types of
access, you must always be sure to define "Full Access" as containing
the names of all possible permissions for your object.
Example:
__ac_types__=(
('Full Access', map(lambda x: x[0], __ac_permissions__)),
('Change', ['Add Objects', 'Add Properties', 'Change Properties']),
)
Developers may also provide pre-defined role names that are
not deletable via the interface by specifying an __ac_roles__
attribute. This is probably not something we'll ever use under
the new architecture, but it's there if you need it.
Example:
__ac_roles__=('Manager', 'Anonymous')

"""SecurityInfo objects and access control constants.
SecurityInfo objects are used in class definitions to allow
a declarative style of associating access control information
with class attributes.
More information on using SecurityInfo and guide to Zope security
for developers can be found in the dev.zope.org "Declarative Security"
project:
http://dev.zope.org/Wikis/DevSite/Projects/DeclarativeSecurity
While SecurityInfo objects largely remove the need for Python
programmers to care about the underlying implementation, there
are several constants defined that should be used by code that
must set __roles__ attributes directly. (the constants are also
accessible from the AccessControl namespace). The defined access
control constants and their meanings are:
ACCESS_PUBLIC: accessible from restricted code and possibly
through the web (if object has a docstring)
ACCESS_PRIVATE: accessible only from python code
ACCESS_NONE: no access

'''Collect rules for access to objects that don\'t have roles.
The rules are expressed as a mapping from type -> assertion
An assertion can be:
- A dict
- A callable
- Something with a truth value
If the assertion is a callable, then it will be called with
a name being accessed and the name used. Its return value is ignored,
but in may veto an access by raising an exception.
If the assertion is a dictionary, then the keys are attribute names.
The values may be callables or objects with boolean values. If a value
is callable, it will be called with the object we are accessing an
attribute of and the attribute name. It should return an attribute
value. Callables are often used to returned guarded versions of
methods. Otherwise, accesses are allowed if values in this dictionary
are true and disallowed if the values are false or if an item for an
attribute name is not present.
If the assertion is not a dict and is not callable, then access to
unprotected attributes is allowed if the assertion is true, and
disallowed otherwise.

or in ZopeSecurityPolicy. :(

# ContainerAssertions maps types to a either a dict, a function, or a
# simple boolean value. When guarded_getattr checks the type of its
# first argument against ContainerAssertions, and invokes checking
# logic depending on what value it finds.
# If the value for a type is:
# - a boolean value:
# - the value determines whether access is allowed
# - a function (or callable):
# - The function is called with the name of the attribute and

# - The dict maps attribute names to boolean values or functions.

Request method decorators
=========================
Using request method decorators, you can limit functions or methods to only
be callable when the HTTP request was made using a particular method.
To limit access to a function or method to POST requests, use the requestmethod
decorator factory::
>>> from AccessControl.requestmethod import requestmethod
>>> @requestmethod('POST')
... def foo(bar, REQUEST):
... return bar
When this method is accessed through a request that does not use POST, the
Forbidden exception will be raised::
>>> foo('spam', GET)
Traceback (most recent call last):
...
Forbidden: Request must be POST
Only when the request was made using POST, will the call succeed::
>>> foo('spam', POST)
'spam'
It doesn't matter if REQUEST is a positional or a keyword parameter::
>>> @requestmethod('POST')
... def foo(bar, REQUEST=None):
... return bar
>>> foo('spam', REQUEST=GET)
Traceback (most recent call last):
...
Forbidden: Request must be POST
*Not* passing an optional REQUEST always succeeds::
>>> foo('spam')
'spam'
Note that the REQUEST parameter is a requirement for the decorator to operate,
not including it in the callable signature results in an error::
>>> @requestmethod('POST')
... def foo(bar):
... return bar
Traceback (most recent call last):
...
ValueError: No REQUEST parameter in callable signature
Because the Zope Publisher uses introspection to match REQUEST variables
against callable signatures, the result of the decorator must match the
original closely, and keyword parameter defaults must be preserved::
>>> import inspect
>>> mutabledefault = dict()
>>> @requestmethod('POST')
... def foo(bar, baz=mutabledefault, egg=mutabledefault, REQUEST=None, *args):
... return bar, baz is mutabledefault, egg is None, REQUEST
>>> inspect.getargspec(foo)[:3]
(['bar', 'baz', 'egg', 'REQUEST'], 'args', None)
>>> foo('spam', egg=None)
('spam', True, True, None)
>>> foo(monty='python')
Traceback (most recent call last):
...
TypeError: foo() got an unexpected keyword argument 'monty'
The requestmethod decorator factory can be used for any request method, simply
pass in the desired request method::
>>> @requestmethod('PUT')

"""This test demonstrates that the traditional declarative security of
Zope 2 can be replaced by ZCML statements without any loss of
information.
>>> from zope.component.testing import setUp, tearDown
>>> setUp()
We start out with two classes, ``Dummy1`` and ``Dummy2``. They
are identical in every way, except that ``Dummy2`` has security
declarations and ``Dummy1`` does not. Before we do anything, none
of them have security access controls:
>>> from AccessControl.tests.testZCML import Dummy1, Dummy2
>>> hasattr(Dummy1, '__ac_permissions__')
False
>>> hasattr(Dummy2, '__ac_permissions__')
False
Before we can make security declarations through ZCML, we need to
register the directive and the permission:
>>> import AccessControl
>>> from zope.configuration.xmlconfig import XMLConfig
>>> XMLConfig('meta.zcml', AccessControl)()
>>> XMLConfig('permissions.zcml', AccessControl)()
Now we initialize the security for ``Dummy2`` and provide some
ZCML declarations for ``Dummy1``:
>>> from StringIO import StringIO
>>> configure_zcml = StringIO('''
... <configure xmlns="http://namespaces.zope.org/zope">
... <class class="AccessControl.tests.testZCML.Dummy1">
... <allow attributes="foo" />
... <!--deny attributes="baz" /--> <!-- XXX not yet supported -->
... </class>
... <class class="AccessControl.tests.testZCML.Dummy1">
... <require attributes="bar keg"
... permission="zope2.ViewManagementScreens"

... </configure>
... ''')
>>> from zope.configuration.xmlconfig import xmlconfig
>>> xmlconfig(configure_zcml)
>>> from AccessControl.class_init import InitializeClass
>>> InitializeClass(Dummy2)
Now we compare their access controls:
>>> ac1 = getattr(Dummy1, '__ac_permissions__')
>>> ac2 = getattr(Dummy2, '__ac_permissions__')
>>> ac1 == ac2
True
Now we look at the individual permissions:
>>> from AccessControl.ZopeSecurityPolicy import getRoles
>>> from AccessControl import ACCESS_PUBLIC
>>> from AccessControl import ACCESS_PRIVATE
>>> dummy1 = Dummy1()
>>> getRoles(dummy1, 'bar', dummy1.bar, ('Def',))
('Manager',)
>>> getRoles(dummy1, 'keg', dummy1.keg, ('Def',))
('Manager',)
>>> getRoles(dummy1, 'foo', dummy1.foo, ('Def',)) is ACCESS_PUBLIC
True
#>>> getRoles(dummy1, 'baz', dummy1.baz, ('Def',)) is ACCESS_PRIVATE
#True XXX Not yet supported.
>>> dummy2 = Dummy2()
>>> getRoles(dummy2, 'bar', dummy2.bar, ('Def',))
('Manager',)
>>> getRoles(dummy2, 'keg', dummy2.keg, ('Def',))
('Manager',)
>>> getRoles(dummy2, 'foo', dummy2.foo, ('Def',)) is ACCESS_PUBLIC
True
>>> getRoles(dummy2, 'baz', dummy2.baz, ('Def',)) is ACCESS_PRIVATE
True

Test checkPermission
>>> from zope.component.testing import setUp, tearDown
>>> setUp()
>>> from zope.component import eventtesting
>>> eventtesting.setUp()
zope.security has a function zope.security.checkPermission which provides
an easy way of checking whether the currently authenticated user
has the permission to access an object. The function delegates to
the security policy's checkPermission() method.
Zope2 has the same function, AccessControl.security.checkPermission,
but in a Zope2-compatible implementation. It too uses the currently
active security policy of Zope 2 for the actual permission
checking.
>>> import AccessControl
>>> from zope.configuration.xmlconfig import XMLConfig
>>> XMLConfig('meta.zcml', AccessControl)()
>>> XMLConfig('permissions.zcml', AccessControl)()
>>> from AccessControl.tests.testZCML import Dummy5
>>> dummy = Dummy5()
In the following we want to test AccessControl's checkPermission function.
What we want to assure is that checkPermission translates the Zope 2
permissions correctly, especially the edge cases:
a) zope2.Public (which should always be available to everyone)
>>> from AccessControl.security import checkPermission
>>> checkPermission('zope2.Public', dummy)
True
b) zope2.Private (which should never available to anyone)
>>> checkPermission('zope.Private', dummy)
False
>>> checkPermission('zope2.Private', dummy)
False
Any other standard Zope 2 permission will also resolve correctly:
>>> checkPermission('zope2.ViewManagementScreens', dummy)
False
Invalid permissions will obviously result in a negative response:
>>> checkPermission('notapermission', dummy)
False
In addition to using AccessControl's ``checkPermission`` function
directly, we also expect the same behaviour when we use zope.security's
checkPermission function. Code from within other Zope packages will use
that and therefore it should work transparently.
For that to work, a new AccessControl "interaction" needs to be started
(the old one from placelesssetup needs to be ended first):
>>> from zope.security.management import endInteraction
>>> endInteraction()
>>> from AccessControl.security import newInteraction
>>> newInteraction()
a) zope2.Public (which should always be available to everyone)
>>> from zope.security import checkPermission
>>> checkPermission('zope2.Public', dummy)
True
b) zope2.Private (which should never available to anyone)
>>> checkPermission('zope.Private', dummy)
False
>>> checkPermission('zope2.Private', dummy)
False
Any other standard Zope 2 permission will also resolve correctly:
>>> checkPermission('zope2.ViewManagementScreens', dummy)
False
Invalid permissions will obviously result in a negative response:
>>> checkPermission('notapermission', dummy)
False
Clean up:
>>> tearDown()
