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
4.0.6 (2013-01-03)
- Updated Trove classifiers.
4.0.5 (2012-12-14)
- Fixed the C-extensions under Py3k (previously they compiled but were not importable).
4.0.4 (2012-12-11)
- Added support for Python 3.3.
- C extenstions now build under Python 3.2, passing the same tests as the pure-Python reference implementation.
4.0.3 (2012-11-19)
- 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.
4.0.2 (2012-08-27)
- Correct initialization functions in renamed _timestamp extension.
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).
