-#Revision 1.20 2002/07/19 03:36:34 richard
-#Implemented the destroy() method needed by the session database (and possibly
-#others). At the same time, I removed the leading underscores from the hyperdb
-#methods that Really Didn't Need Them.
-#The journal also raises IndexError now for all situations where there is a
-#request for the journal of a node that doesn't have one. It used to return
-#[] in _some_ situations, but not all. This _may_ break code, but the tests
-#pass...
-#
-#Revision 1.19 2002/07/14 02:05:53 richard
-#. all storage-specific code (ie. backend) is now implemented by the backends
-#
-#Revision 1.18 2002/05/15 06:21:21 richard
-# . node caching now works, and gives a small boost in performance
-#
-#As a part of this, I cleaned up the DEBUG output and implemented TRACE
-#output (HYPERDBTRACE='file to trace to') with checkpoints at the start of
-#CGI requests. Run roundup with python -O to skip all the DEBUG/TRACE stuff
-#(using if __debug__ which is compiled out with -O)
-#
-#Revision 1.17 2002/04/03 05:54:31 richard
-#Fixed serialisation problem by moving the serialisation step out of the
-#hyperdb.Class (get, set) into the hyperdb.Database.
-#
-#Also fixed htmltemplate after the showid changes I made yesterday.
-#
-#Unit tests for all of the above written.
-#
-#Revision 1.16 2002/02/27 03:40:59 richard
-#Ran it through pychecker, made fixes
-#
-#Revision 1.15 2002/02/16 09:15:33 richard
-#forgot to patch bsddb backend too
-#
-#Revision 1.14 2002/01/22 07:21:13 richard
-#. fixed back_bsddb so it passed the journal tests
-#
-#... it didn't seem happy using the back_anydbm _open method, which is odd.
-#Yet another occurrance of whichdb not being able to recognise older bsddb
-#databases. Yadda yadda. Made the HYPERDBDEBUG stuff more sane in the
-#process.
-#
-#Revision 1.13 2001/12/10 22:20:01 richard
-#Enabled transaction support in the bsddb backend. It uses the anydbm code
-#where possible, only replacing methods where the db is opened (it uses the
-#btree opener specifically.)
-#Also cleaned up some change note generation.
-#Made the backends package work with pydoc too.
-#
-#Revision 1.12 2001/11/21 02:34:18 richard
-#Added a target version field to the extended issue schema
-#
-#Revision 1.11 2001/10/09 23:58:10 richard
-#Moved the data stringification up into the hyperdb.Class class' get, set
-#and create methods. This means that the data is also stringified for the
-#journal call, and removes duplication of code from the backends. The
-#backend code now only sees strings.
-#
-#Revision 1.10 2001/10/09 07:25:59 richard
-#Added the Password property type. See "pydoc roundup.password" for
-#implementation details. Have updated some of the documentation too.
-#
-#Revision 1.9 2001/08/12 06:32:36 richard
-#using isinstance(blah, Foo) now instead of isFooType
-#
-#Revision 1.8 2001/08/07 00:24:42 richard
-#stupid typo
-#
-#Revision 1.7 2001/08/07 00:15:51 richard
-#Added the copyright/license notice to (nearly) all files at request of
-#Bizar Software.
-#
-#Revision 1.6 2001/07/30 02:36:23 richard
-#Handle non-existence of db files in the other backends (code from anydbm).
-#
-#Revision 1.5 2001/07/30 01:41:36 richard
-#Makes schema changes mucho easier.
-#
-#Revision 1.4 2001/07/23 08:25:33 richard
-#more handling of bad journals
-#
-#Revision 1.3 2001/07/23 08:20:44 richard
-#Moved over to using marshal in the bsddb and anydbm backends.
-#roundup-admin now has a "freshen" command that'll load/save all nodes (not
-# retired - mod hyperdb.Class.list() so it lists retired nodes)
-#
-#Revision 1.2 2001/07/23 07:56:05 richard
-#Storing only marshallable data in the db - no nasty pickled class references.
-#
-#Revision 1.1 2001/07/23 07:22:13 richard
-#*sigh* some databases have _foo.so as their underlying implementation.
-#This time for sure, Rocky.
-#
-#Revision 1.1 2001/07/23 07:15:57 richard
-#Moved the backends into the backends package. Anydbm hasn't been tested at all.
-#
-#Revision 1.1 2001/07/23 06:23:41 richard
-#moved hyper_bsddb.py to the new backends package as bsddb.py
