ZODB3 Description

Zope Object Database: object database and persistence ZODB3 (Zope Object Database) provides an object-oriented database for Python that provides a high-degree of transparency. Applications can take advantage of object database features with few, if any, changes to application logic. ZODB includes features such as a plugable storage interface, rich transaction support, and undo.The ZODB package provides a set of tools for using the Zope Object Database (ZODB). The components you get with the ZODB release are as follows: * Core ZODB, including the persistence machinery * Standard storages such as FileStorage * The persistent BTrees modules * ZEO, for scalability needs * documentation (needs more work)Our primary development platforms are Linux, Mac OS X, and Windows XP. The test suite should pass without error on all of these platforms, although it can take a long time on Windows -- longer if you use ZoneAlarm. Many particularly slow tests are skipped unless you pass --all as an argument to test.py. Requirements: · Python What's New in This Release: Bugs Fixed: · A ZEO threading bug could cause transactions to read inconsistent data. (This sometimes caused an AssertionError in Connection._setstate_noncurrent.) · DemoStorage.loadBefore sometimes returned invalid data which would trigger AssertionErrors in ZODB.Connection. · History support was broken when using stprages that work with ZODB 3.8 and 3.9. · zope.testing was an unnecessary non-testing dependency. · Internal ZEO errors were logged at the INFO level, rather than at the error level. · The FileStorage backup and restore script, repozo, gave a deprecation warning under Python 2.6. · C Header files weren't installed correctly. · The repozo backup utility gave deprecation warnings when run.
