/*
|
|
* Handwritten code to wrap version 3.x of the Berkeley DB library,
|
|
* written to replace a SWIG-generated file. It has since been updated
|
|
* to compile with BerkeleyDB versions 3.2 through 4.1.
|
|
*
|
|
* 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.
|
|
*
|
|
* 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.
|
|
*
|
|
* This module contains 5 types:
|
|
*
|
|
* DB (Database)
|
|
* DBCursor (Database Cursor)
|
|
* DBEnv (database environment)
|
|
* DBTxn (An explicit database transaction)
|
|
* DBLock (A lock handle)
|
|
*

/*
|

* Portions of this module, associated unit tests and build scripts are the

* result of a contract with The Written Word (http://thewrittenword.com/)
|
|
* Many thanks go out to them for causing me to raise the bar on quality and
|
|
* functionality, resulting in a better bsddb3 package for all of us to use.
