persistent 4.0.1

Translucent persistent objects

persistent: automatic persistence for Python objects

This package contains a generic persistence implementation for Python. It forms the core protocol for making objects interact “transparently” with a database such as the ZODB.

Please see the Sphinx documentation (docs/index.rst) for further information.

persistent Changelog

4.0.1 (2012-08-26)

• 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.

4.0.0 (2012-08-11)

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).
