Translucent persistent objects
Project description
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
4.0.3 (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).
