Persistent

==================

- Added support for Python 3.3.

- C extenstions now build under Python 3.2, passing the same tests as
the pure-Python reference implementation.

==================

- Fixed: In the C implimentation, an integer was compared with a
pointer, with undefined results and a compiler warning.

- Fixed: the Python implementation of the ``_p_estimated_size`` propety
didn't support deletion.

- Simplified implementation of the ``_p_estimated_size`` property to
only accept integers. A TypeError is raised if an incorrect type is
provided.

==================

- Correct initialization functions in renamed ``_timestamp`` extension.

==================

- Worked around test failure due to overflow to long on 32-bit systems.

- Renamed ``TimeStamp`` extension module to avoid clash with pure-Python
``timestamp`` module on case-insensitive filesystems.

N.B: the canonical way to import the ``TimeStamp`` class is now::

from persistent.timestamp import TimeStamp

which will yield the class from the extension module (if available),
falling back to the pure-Python reference implementation.

==================

Platform Changes
----------------

- Added explicit support for Python 3.2 and PyPy.

- Note that the C implementations of Persistent, PickleCache, and Timestamp
are not built (yet) on these platforms.

- Dropped support for Python < 2.6.

Testing Changes
---------------

- 100% unit test coverage.

- Removed all ``ZODB``-dependent tests:

- Rewrote some to avoid the dependency

- Cloned the remainder into new ``ZODB.tests`` modules.

- Refactored some doctests refactored as unittests.

- Completed pure-Python reference implementations of 'Persistent',
'PickleCache', and 'TimeStamp'.

- All covered platforms tested under ``tox``.

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

- Added ``setup.py dev`` alias (installs ``nose`` and ``coverage``).

- Dropped dependency on ``zope.testing`` / ``zope.testrunner``: tests now
run with ``setup.py test``.

Documentation Changes
---------------------

- Refactored many Doctests as Sphinx documentation (snippets are exercised
via 'tox').

- Added ``setup.py docs`` alias (installs ``Sphinx`` and
``repoze.sphinx.autointerface``).
