Proxies are special objects which serve as mostly-transparent
wrappers around another object, intervening in the apparent behavior of
the wrapped object only when necessary to apply the policy (e.g., access
checking, location brokering, etc.) for which the proxy is responsible.

zope.proxy is implemented via a C extension module, which lets it do things
like lie about its own ``__class__`` that are difficult in pure Python (and
were completely impossible before metaclasses).  It also proxies all the
internal slots (such as ``__int__``/``__str__``/``__add__``).

=========
 Changes
=========

4.3.5 (2020-03-16)
==================

- Stop installing C header files on PyPy (which is what zope.proxy before 4.3.4
  used to do), fixes `issue 39
  <https://github.com/zopefoundation/zope.proxy/issues/39>`_.


4.3.4 (2020-03-13)
==================

- Fix a compilation warning on Python 3.8. The slot ``tp_print``
  changed to ``tp_vectorcall_offset`` in 3.8 and must not be set.
  Prior to 3.8, it was reserved and ignored in all Python 3 versions.
  See `issue 36
  <https://github.com/zopefoundation/zope.proxy/issues/36>`_.

- Remove deprecated use of setuptools features.  See `issue 38
  <https://github.com/zopefoundation/zope.proxy/issues/38>`_.


4.3.3 (2019-11-11)
==================

- Add support for Python 3.8.

- Drop support for Python 3.4.


4.3.2 (2019-07-12)
==================

- Fix error handling in ``ProxyBase.__setattr__``: any the exception raised by
  ``PyString_AsString``/``PyUnicode_AsUTF8`` would be silently swallowed up
  and ignored.  See `issue 31
  <https://github.com/zopefoundation/zope.proxy/issues/31>`_.


4.3.1 (2018-08-09)
==================

- Simplify the internal C handling of attribute names in
  ``__getattribute__`` and ``__setattr__``.

- Make building the C extension optional. We still attempt to build it
  on supported platforms, but we allow it to fail in case of a missing
  compiler or headers. See `issue 26
  <https://github.com/zopefoundation/zope.proxy/issues/26>`_.

- Test the PURE_PYTHON environment and PyPy3 on Travis CI.

- Add support for Python 3.7.

4.3.0 (2017-09-13)
==================

- Fix a potential rare crash when deallocating proxies. See `issue 20
  <https://github.com/zopefoundation/zope.proxy/issues/20>`_.

- Drop support for Python 3.3.

- Drop support for "python setup.py test".

- 100% test coverage.

- Fix indexing pure-Python proxies with slices under Python 3, and
  restore the use of ``__getslice__`` (if implemented by the target's
  type) under Python 2. Previously, pure-Python proxies would fail
  with an AttributeError when given a slice on Python 3, and on Python
  2, a custom ``__getslice__`` was ignored. See `issue 21
  <https://github.com/zopefoundation/zope.proxy/issues/21>`_.

4.2.1 (2017-04-23)
==================

- Make the pure-Python implementation of ``sameProxiedObjects`` handle
  ``zope.security`` proxies. See `issue 15 <https://github.com/zopefoundation/zope.proxy/issues/15>`_.

- Add support for Python 3.6.

4.2.0 (2016-05-05)
==================

- Correctly strip ``zope.security`` proxies in ``removeAllProxies``.
  See `issue 13 <https://github.com/zopefoundation/zope.proxy/pull/13>`_.

- Avoid poisoning the user's global wheel cache when testing ``PURE_PYTHON``
  environments under ``tox``,

- Drop support for Python 2.6 and 3.2.

- Add support for Python 3.5.

4.1.6 (2015-06-02)
==================

- Make subclasses of ProxyBase properly delegate ``__module__`` to the
  wrapped object. This fixes some ``zope.interface`` lookups under
  PyPy.

- Make the pure-Python implementation of ProxyBase properly report the
  ``zope.interface`` interfaces implemented by builtin types like
  ``list``. This fixes some ``zope.interface`` lookups under PyPy.

4.1.5 (2015-05-19)
==================

- Make the C implementation proxy ``__unicode__`` correctly.

- Make the C implementation use the standard methods to proxy ``int`` and
  ``float``.

- Make the pure Python implementation handle descriptors defined in
  subclasses like the C version. See
  https://github.com/zopefoundation/zope.proxy/issues/5.

4.1.4 (2014-03-19)
==================

- Add support for Python 3.4.

- Update ``bootstrap.py`` to version 2.2.

4.1.3 (2013-03-12)
==================

- Fix interface object introspection in PyPy. For some reason PyPy makes
  attributes available despite the restrictive ``__slots__`` declaration.

- Add a bunch of tests surrounding interface lookup and adaptation.

4.1.2 (2013-03-11)
==================

- Make ``PyProxyBase.__iter__()`` return the result of
  ``PyProxyBase._wrapped.__iter__`` if available, otherwise falling back to
  Python internals. The previous implementation always created a generator.

- In ``PyProxyBase.__setattr__()``, allow setting of properties on the
  proxy itself. This is needed to properly allow proxy extensions as was
  evidenced int he ``zope.security.decorator`` module.

4.1.1 (2012-12-31)
==================

- Fleshed out PyPI Trove classifiers.

4.1.0 (2012-12-19)
==================

- Enable compilation of dependent modules under Py3k.

- Replace use of ``PyCObject`` APIs with equivalent ``PyCapsule`` APIs,
  except under Python 2.6.

  N.B.  This change is an ABI incompatibility under Python 2.7:
        extensions built under Python 2.7 against 4.0.x versions of
        ``zope.proxy`` must be rebuilt.

4.0.1 (2012-11-21)
==================

- Add support for Python 3.3.

4.0.0 (2012-06-06)
==================

- Add support for PyPy.

  N.B.:  the C extension is *not* built under PyPy.

- Add a pure-Python reference / fallback implementations of
  ``zope.proxy.ProxyBase`` and the proxy module API functions.

  N.B.:  the pure-Python proxy implements all regular features of
  ``ProxyBase``;  however, it does not exclude access to the wrapped object
  in the same way that the C version does.  If you need that information
  hiding (e.g., to implement security sandboxing), you still need to use
  the C version.

- Add support for continuous integration using ``tox`` and ``jenkins``.

- 100% unit test coverage.

- Add Sphinx documentation:  moved doctest examples to API reference.

- Add 'setup.py docs' alias (installs ``Sphinx`` and dependencies).

- Add 'setup.py dev' alias (runs ``setup.py develop`` plus installs
  ``nose`` and ``coverage``).

- Replace deprecated ``zope.interface.implements`` usage with equivalent
  ``zope.interface.implementer`` decorator.

- Drop support for Python 2.4 and 2.5.

- Add Python 3.2 support.

3.6.1 (2010-07-06)
==================

- Make tests compatible with Python 2.7.

3.6.0 (2010-04-30)
==================

- Remove test extra and the remaining dependency on zope.testing.

- Remove use of 'zope.testing.doctestunit' in favor of stdlib's 'doctest.

3.5.0 (2009/01/31)
==================

- Add support to bootstrap on Jython.

- Use ``zope.container`` instead of ``zope.app.container``.

3.4.2 (2008/07/27)
==================

- Make C code compatible with Python 2.5 on 64bit architectures.

3.4.1 (2008/06/24)
==================

- Bug: Update ``setup.py`` script to conform to common layout. Also updated
  some of the fields.

- Bug: Honor pre-cooked indices for tuples and lists in the ``__getslice__()``
  and ``__setslice__()`` methods. See
  http://docs.python.org/ref/sequence-methods.html.

3.4.0 (2007/07/12)
==================

- Feature: Add a ``decorator`` module that supports declaring interfaces on
  proxies that get blended with the interfaces of the things they proxy.

3.3.0 (2006/12/20)
==================

- Corresponds to the verison of the ``zope.proxy`` package shipped as part of
  the Zope 3.3.0 release.


3.2.0 (2006/01/05)
==================

- Corresponds to the verison of the ``zope.proxy`` package shipped as part of
  the Zope 3.2.0 release.


3.0.0 (2004/11/07)
==================

- Corresponds to the verison of the ``zope.proxy`` package shipped as part of
  the Zope X3.0.0 release.
