-# Added explicit closing of backend database handles.
-#
-# Revision 1.72 2002/07/09 21:53:38 gmcm
-# Optimize Class.find so that the propspec can contain a set of ids to match.
-# This is used by indexer.search so it can do just one find for all the index matches.
-# This was already confusing code, but for common terms (lots of index matches),
-# it is enormously faster.
-#
-# Revision 1.71 2002/07/09 03:02:52 richard
-# More indexer work:
-# - all String properties may now be indexed too. Currently there's a bit of
-# "issue" specific code in the actual searching which needs to be
-# addressed. In a nutshell:
-# + pass 'indexme="yes"' as a String() property initialisation arg, eg:
-# file = FileClass(db, "file", name=String(), type=String(),
-# comment=String(indexme="yes"))
-# + the comment will then be indexed and be searchable, with the results
-# related back to the issue that the file is linked to
-# - as a result of this work, the FileClass has a default MIME type that may
-# be overridden in a subclass, or by the use of a "type" property as is
-# done in the default templates.
-# - the regeneration of the indexes (if necessary) is done once the schema is
-# set up in the dbinit.

-# Revision 1.64 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

-# (using if __debug__ which is compiled out with -O)
-#
-# Revision 1.63 2002/04/15 23:25:15 richard
-# . node ids are now generated from a lockable store - no more race conditions
-#
-# We're using the portalocker code by Jonathan Feinberg that was contributed
-# to the ASPN Python cookbook. This gives us locking across Unix and Windows.

-#
-# Also fixed htmltemplate after the showid changes I made yesterday.
-#
-# Unit tests for all of the above written.
-#
-# Revision 1.59.2.2 2002/04/20 13:23:33 rochecompaan
-# We now have a separate search page for nodes. Search links for
-# different classes can be customized in instance_config similar to

-#
-# Revision 1.59.2.1 2002/04/19 19:54:42 rochecompaan

-# Revision 1.53 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.

-# . the transaction cache had broken the roundupdb.Class set() reactors
-# . newly-created author users in the mailgw weren't being committed to the db

-# Stuff that made it into CHANGES.txt (ie. the stuff I was actually working

-#
-# Revision 1.43 2001/12/20 06:13:24 rochecompaan

-# admin tool now complains if a "find" is attempted with a non-link property.
-#
-# Revision 1.25 2001/10/11 00:17:51 richard
-# Reverted a change in hyperdb so the default value for missing property
-# values in a create() is None and not '' (the empty string.) This obviously
-# breaks CSV import/export - the string 'None' will be created in an
-# export/import operation.
-#
-# Revision 1.24 2001/10/10 03:54:57 richard
-# Added database importing and exporting through CSV files.
-# Uses the csv module from object-craft for exporting if it's available.
-# Requires the csv module for importing.
-#
-# Revision 1.23 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 1.22 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 1.21 2001/10/05 02:23:24 richard
-# . roundup-admin create now prompts for property info if none is supplied
-# on the command-line.
-# . hyperdb Class getprops() method may now return only the mutable
-# properties.
-# . Login now uses cookies, which makes it a whole lot more flexible. We can
-# now support anonymous user access (read-only, unless there's an
-# "anonymous" user, in which case write access is permitted). Login
-# handling has been moved into cgi_client.Client.main()
-# . The "extended" schema is now the default in roundup init.
-# . The schemas have had their page headings modified to cope with the new
-# login handling. Existing installations should copy the interfaces.py
-# file from the roundup lib directory to their instance home.
-# . Incorrectly had a Bizar Software copyright on the cgitb.py module from
-# Ping - has been removed.
-# . Fixed a whole bunch of places in the CGI interface where we should have
-# been returning Not Found instead of throwing an exception.
-# . Fixed a deviation from the spec: trying to modify the 'id' property of
-# an item now throws an exception.
-#
-# Revision 1.20 2001/10/04 02:12:42 richard
-# Added nicer command-line item adding: passing no arguments will enter an
-# interactive more which asks for each property in turn. While I was at it, I
-# fixed an implementation problem WRT the spec - I wasn't raising a
-# ValueError if the key property was missing from a create(). Also added a
-# protected=boolean argument to getprops() so we can list only the mutable
-# properties (defaults to yes, which lists the immutables).
-#
-# Revision 1.19 2001/08/29 04:47:18 richard
-# Fixed CGI client change messages so they actually include the properties
-# changed (again).
-#
-# Revision 1.18 2001/08/16 07:34:59 richard
-# better CGI text searching - but hidden filter fields are disappearing...
-#
-# Revision 1.17 2001/08/16 06:59:58 richard
-# all searches use re now - and they're all case insensitive
-#
-# Revision 1.16 2001/08/15 23:43:18 richard
-# Fixed some isFooTypes that I missed.
-# Refactored some code in the CGI code.
-#
-# Revision 1.15 2001/08/12 06:32:36 richard
-# using isinstance(blah, Foo) now instead of isFooType
-#
-# Revision 1.14 2001/08/07 00:24:42 richard
-# stupid typo
-#
-# Revision 1.13 2001/08/07 00:15:51 richard
-# Added the copyright/license notice to (nearly) all files at request of
-# Bizar Software.
-#
-# Revision 1.12 2001/08/02 06:38:17 richard
-# Roundupdb now appends "mailing list" information to its messages which
-# include the e-mail address and web interface address. Templates may
-# override this in their db classes to include specific information (support
-# instructions, etc).
-#
-# Revision 1.11 2001/08/01 04:24:21 richard
-# mailgw was assuming certain properties existed on the issues being created.
-#
-# Revision 1.10 2001/07/30 02:38:31 richard
-# get() now has a default arg - for migration only.
-#
-# Revision 1.9 2001/07/29 09:28:23 richard

-#
-# Revision 1.8 2001/07/29 08:27:40 richard

-# drill-down)
-#
-# Revision 1.7 2001/07/29 07:01:39 richard
-# Added vim command to all source so that we don't get no steenkin' tabs :)
-#
-# Revision 1.6 2001/07/29 05:36:14 richard

-#
-# Revision 1.5 2001/07/29 04:05:37 richard

-#
-# Revision 1.4 2001/07/27 06:25:35 richard
-# Fixed some of the exceptions so they're the right type.
-# Removed the str()-ification of node ids so we don't mask oopsy errors any
-# more.
