Description: ``zope.interface`` README
        =========================
        
        This package is intended to be independently reusable in any Python
        project. It is maintained by the `Zope Toolkit project
        <http://docs.zope.org/zopetoolkit/>`_.
        
        This package provides an implementation of "object interfaces" for Python.
        Interfaces are a mechanism for labeling objects as conforming to a given
        API or contract. So, this package can be considered as implementation of
        the `Design By Contract`_ methodology support in Python.

        ============================
        
        3.8.0 (2011-09-22)
        ------------------
        
        - New module ``zope.interface.registry``.  This is code moved from
          ``zope.component.registry`` which implements a basic nonperistent component
          registry as ``zope.interface.registry.Components``.  This class was moved
          from ``zope.component`` to make porting systems (such as Pyramid) that rely
          only on a basic component registry to Python 3 possible without needing to
          port the entirety of the ``zope.component`` package.  Backwards
          compatibility import shims have been left behind in ``zope.component``, so
          this change will not break any existing code.
        
        - New ``tests_require`` dependency: ``zope.event`` to test events sent by
          Components implementation.  The ``zope.interface`` package does not have a
          hard dependency on ``zope.event``, but if ``zope.event`` is importable, it
          will send component registration events when methods of an instance of
          ``zope.interface.registry.Components`` are called.
        
        - New interfaces added to support ``zope.interface.registry.Components``
          addition: ``ComponentLookupError``, ``Invalid``, ``IObjectEvent``,
          ``ObjectEvent``, ``IComponentLookup``, ``IRegistration``,
          ``IUtilityRegistration``, ``IAdapterRegistration``,
          ``ISubscriptionAdapterRegistration``, ``IHandlerRegistration``,
          ``IRegistrationEvent``, ``RegistrationEvent``, ``IRegistered``,
          ``Registered``, ``IUnregistered``, ``Unregistered``,
          ``IComponentRegistry``, and ``IComponents``.
        
        - No longer Python 2.4 compatible (tested under 2.5, 2.6, 2.7, and 3.2).
        
        3.7.0 (2011-08-13)
        ------------------
        
        - Move changes from 3.6.2 - 3.6.5 to a new 3.7.x release line.
        
        3.6.7 (2011-08-20)
        ------------------
        
        - Fix sporadic failures on x86-64 platforms in tests of rich comparisons
          of interfaces.
        
        3.6.6 (2011-08-13)
        ------------------
        
        - LP #570942:  Now correctly compare interfaces  from different modules but
          with the same names.
          
          N.B.: This is a less intrusive / destabilizing fix than the one applied in
          3.6.3:  we only fix the underlying cmp-alike function, rather than adding
          the other "rich comparison" functions.
        
        - Revert to software as released with 3.6.1 for "stable" 3.6 release branch.
        
        3.6.5 (2011-08-11)
        ------------------
        
        - LP #811792:  work around buggy behavior in some subclasses of
          ``zope.interface.interface.InterfaceClass``, which invoke ``__hash__``
          before initializing ``__module__`` and ``__name__``.  The workaround
          returns a fixed constant hash in such cases, and issues a ``UserWarning``.
        
        - LP #804832:  Under PyPy, ``zope.interface`` should not build its C
          extension.  Also, prevent attempting to build it under Jython.
        
        - Add a tox.ini for easier xplatform testing.
        
        - Fix testing deprecation warnings issued when tested under Py3K.
        
        3.6.4 (2011-07-04)
        ------------------
        
        - LP 804951:  InterfaceClass instances were unhashable under Python 3.x.
        
        3.6.3 (2011-05-26)
        ------------------
        
        - LP #570942:  Now correctly compare interfaces  from different modules but
          with the same names.
        
        3.6.2 (2011-05-17)
        ------------------
        
        - Moved detailed documentation out-of-line from PyPI page, linking instead to
          http://docs.zope.org/zope.interface .
        
        - Fixes for small issues when running tests under Python 3.2 using
          ``zope.testrunner``.
        
        - LP # 675064:  Specify return value type for C optimizations module init
          under Python 3:  undeclared value caused warnings, and segfaults on some
          64 bit architectures.
        
        - setup.py now raises RuntimeError if you don't have Distutils installed when
          running under Python 3.
        
        3.6.1 (2010-05-03)
        ------------------
        
        - A non-ASCII character in the changelog made 3.6.0 uninstallable on
          Python 3 systems with another default encoding than UTF-8.
        
        - Fixed compiler warnings under GCC 4.3.3.
        
        3.6.0 (2010-04-29)
        ------------------
        
        - LP #185974:  Clear the cache used by ``Specificaton.get`` inside
          ``Specification.changed``.  Thanks to Jacob Holm for the patch.
        
        - Added support for Python 3.1. Contributors:
        
            Lennart Regebro
            Martin v Loewis
            Thomas Lotze
            Wolfgang Schnerring
        
          The 3.1 support is completely backwards compatible. However, the implements
          syntax used under Python 2.X does not work under 3.X, since it depends on
          how metaclasses are implemented and this has changed. Instead it now supports
          a decorator syntax (also under Python 2.X)::
        
            class Foo:
                implements(IFoo)
                ...
        
          can now also be written::
        
            @implementor(IFoo):
            class Foo:
                ...
        
          There are 2to3 fixers available to do this change automatically in the
          zope.fixers package.
        
        - Python 2.3 is no longer supported.
        
        
        3.5.4 (2009-12-23)
        ------------------
        
        - Use the standard Python doctest module instead of zope.testing.doctest, which
          has been deprecated.
        
        
        3.5.3 (2009-12-08)
        ------------------
        
        - Fix an edge case: make providedBy() work when a class has '__provides__' in
          its __slots__ (see http://thread.gmane.org/gmane.comp.web.zope.devel/22490)
        
        
        3.5.2 (2009-07-01)
        ------------------
        
        - BaseAdapterRegistry.unregister, unsubscribe: Remove empty portions of
          the data structures when something is removed.  This avoids leaving
          references to global objects (interfaces) that may be slated for
          removal from the calling application.
        
        
        3.5.1 (2009-03-18)
        ------------------
        
        - verifyObject: use getattr instead of hasattr to test for object attributes
          in order to let exceptions other than AttributeError raised by properties
          propagate to the caller
        
        - Add Sphinx-based documentation building to the package buildout
          configuration. Use the ``bin/docs`` command after buildout.
        
        - Improve package description a bit. Unify changelog entries formatting.
        
        - Change package's mailing list address to zope-dev at zope.org as
          zope3-dev at zope.org is now retired.
        
        
        3.5.0 (2008-10-26)
        ------------------
        
        - Fixed declaration of _zope_interface_coptimizations, it's not a top level
          package.
        
        - Add a DocTestSuite for odd.py module, so their tests are run.
        
        - Allow to bootstrap on Jython.
        
        - Fix https://bugs.launchpad.net/zope3/3.3/+bug/98388: ISpecification
          was missing a declaration for __iro__.
        
        - Added optional code optimizations support, which allows the building
          of C code optimizations to fail (Jython).
        
        - Replaced `_flatten` with a non-recursive implementation, effectively making
          it 3x faster.
        
        
        3.4.1 (2007-10-02)
        ------------------
        
        - Fixed a setup bug that prevented installation from source on systems
          without setuptools.
        
        
        3.4.0 (2007-07-19)
        ------------------
        
        - Final release for 3.4.0.
        
        
        3.4.0b3 (2007-05-22)
        --------------------
        
        
        - Objects with picky custom comparison methods couldn't be added to
          component registries.  Now, when checking whether an object is
          already registered, identity comparison is used.
        
        
        3.3.0.1 (2007-01-03)
        --------------------
        
        - Made a reference to OverflowWarning, which disappeared in Python
          2.5, conditional.
        
        
        3.3.0 (2007/01/03)
        ------------------
        
        New Features
        ++++++++++++
        
        - The adapter-lookup algorithim was refactored to make it
          much simpler and faster.  
        
          Also, more of the adapter-lookup logic is implemented in C, making
          debugging of application code easier, since there is less
          infrastructre code to step through.
        
        - We now treat objects without interface declarations as if they
          declared that they provide zope.interface.Interface.
        
        - There are a number of richer new adapter-registration interfaces
          that provide greater control and introspection.
        
        - Added a new interface decorator to zope.interface that allows the
          setting of tagged values on an interface at definition time (see
          zope.interface.taggedValue).
        
        Bug Fixes
        +++++++++
        
        - A bug in multi-adapter lookup sometimes caused incorrect adapters to
          be returned.
        
        
        3.2.0.2 (2006-04-15)
        --------------------
        
        - Fix packaging bug:  'package_dir' must be a *relative* path.
        
        
        3.2.0.1 (2006-04-14)
        --------------------
        
        - Packaging change:  suppress inclusion of 'setup.cfg' in 'sdist' builds.
        
        
        3.2.0 (2006-01-05)
        ------------------
        
        - Corresponds to the verison of the zope.interface package shipped as part of
          the Zope 3.2.0 release.
        
        
        3.1.0 (2005-10-03)
        ------------------
        
        - Corresponds to the verison of the zope.interface package shipped as part of
          the Zope 3.1.0 release.
        
        - Made attribute resolution order consistent with component lookup order,
          i.e. new-style class MRO semantics.
        
        - Deprecated 'isImplementedBy' and 'isImplementedByInstancesOf' APIs in
          favor of 'implementedBy' and 'providedBy'.
        
        
        3.0.1 (2005-07-27)
        ------------------
        
        - Corresponds to the verison of the zope.interface package shipped as part of
          the Zope X3.0.1 release.
        
        - Fixed a bug reported by James Knight, which caused adapter registries
          to fail occasionally to reflect declaration changes.
        
        
        3.0.0 (2004-11-07)
        ------------------
        
        - Corresponds to the verison of the zope.interface package shipped as part of
          the Zope X3.0.0 release.
