* Handwritten code to wrap version 3.x of the Berkeley DB library,
Port BerkeleyDB 4.1 support from the pybsddb project. bsddb is now at version 4.1.1 and works with up to BerkeleyDB 4.1.25.
2002-12-31 04:53:52 +08:00

* to compile with BerkeleyDB versions 3.2 through 4.1.

2002-11-19 16:09:52 +08:00
*
* This module was started by Andrew Kuchling to remove the dependency
* on SWIG in a package by Gregory P. Smith <greg@electricrain.com> who
* based his work on a similar package by Robin Dunn <robin@alldunn.com>
* which wrapped Berkeley DB 2.7.x.
*
Port BerkeleyDB 4.1 support from the pybsddb project. bsddb is now at version 4.1.1 and works with up to BerkeleyDB 4.1.25.
2002-12-31 04:53:52 +08:00
* Development of this module then returned full circle back to Robin Dunn
* who worked on behalf of Digital Creations to complete the wrapping of
* the DB 3.x API and to build a solid unit test suite. Robin has
* since gone onto other projects (wxPython).
*
* Gregory P. Smith <greg@electricrain.com> is once again the maintainer.
*
* Use the pybsddb-users@lists.sf.net mailing list for all questions.
* Things can change faster than the header of this file is updated.
Import PyBSDDB 3.4.0. Rename historical wrapper to bsddb185.

*
* DB (Database)
* DBCursor (Database Cursor)
* DBEnv (database environment)
* DBTxn (An explicit database transaction)
* DBLock (A lock handle)
*
