-#Revision 1.66 2002/09/01 04:32:30 richard
-#. Lots of cleanup in the classic html (stylesheet, search page, index page, ...)
-#. Reinstated searching, but not query saving yet
-#. Filtering only allows sorting and grouping by one property - all backends
-# now implement this behaviour.
-#. Nosy list journalling turned off by default, everything else is on.
-#. Added some convenience methods (reverse, propchanged, [item] accesses, ...)
-#. Did I mention the stylesheet is much cleaner now? :)

-#In preparing to turn back on link/unlink journal events (by default these

-#Session storage in the hyperdb was horribly, horribly inefficient. We use

-#backend or RDB backend if necessary.
-#Much, much better.
-#
-#Revision 1.54 2002/07/26 08:26:59 richard
-#Very close now. The cgi and mailgw now use the new security API. The two
-#templates have been migrated to that setup. Lots of unit tests. Still some
-#issue in the web form for editing Roles assigned to users.
-#
-#Revision 1.53 2002/07/25 07:14:06 richard
-#Bugger it. Here's the current shape of the new security implementation.
-#Still to do:
-# . call the security funcs from cgi and mailgw
-# . change shipped templates to include correct initialisation and remove
-# the old config vars
-#... that seems like a lot. The bulk of the work has been done though. Honest :)
-#
-#Revision 1.52 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...

-#Added reindex command to roundup-admin.
-#Fixed reindex on first access.
-#Also fixed reindexing of entries that change.
-#
-#Revision 1.39 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 1.38 2002/07/08 06:58:15 richard
-#cleaned up the indexer code:
-# - it splits more words out (much simpler, faster splitter)
-# - removed code we'll never use (roundup.roundup_indexer has the full
-# implementation, and replaces roundup.indexer)
-# - only index text/plain and rfc822/message (ideas for other text formats to
-# index are welcome)
-# - added simple unit test for indexer. Needs more tests for regression.
-#
-#Revision 1.37 2002/06/20 23:52:35 richard

-#Merged search_indexing-branch with HEAD
-#
-#Revision 1.34 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 1.33 2002/04/24 10:38:26 rochecompaan
-#All database files are now created group readable and writable.
-#
-#Revision 1.32 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.
-#
-#Revision 1.31 2002/04/03 05:54:31 richard
-#Fixed serialisation problem by moving the serialisation step out of the

-#Also fixed htmltemplate after the showid changes I made yesterday.
-#
-#Unit tests for all of the above written.

-# ATTENTION: blobfiles now creates subdirectories for files.
-#
-#Revision 1.28 2002/02/16 09:14:17 richard
-# . #514854 ] History: "User" is always ticket creator
-#
-#Revision 1.27 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 1.26 2002/01/22 05:18:38 rochecompaan

-#You can now use the roundup-admin tool to pack the database
-#
-#Revision 1.23 2002/01/18 04:32:04 richard
-#Rollback was breaking because a message hadn't actually been written to the file. Needs
-#more investigation.
-#
-#Revision 1.22 2002/01/14 02:20:15 richard
-# . changed all config accesses so they access either the instance or the
-# config attriubute on the db. This means that all config is obtained from
-# instance_config instead of the mish-mash of classes. This will make
-# switching to a ConfigParser setup easier too, I hope.
-#
-#At a minimum, this makes migration a _little_ easier (a lot easier in the
-#0.5.0 switch, I hope!)
-#
-#Revision 1.21 2002/01/02 02:31:38 richard
-#Sorry for the huge checkin message - I was only intending to implement #496356
-#but I found a number of places where things had been broken by transactions:
-# . modified ROUNDUPDBSENDMAILDEBUG to be SENDMAILDEBUG and hold a filename
-# for _all_ roundup-generated smtp messages to be sent to.
-# . 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
-#on when I found that stuff :):
-# . #496356 ] Use threading in messages
-# . detectors were being registered multiple times
-# . added tests for mailgw
-# . much better attaching of erroneous messages in the mail gateway
-#
-#Revision 1.20 2001/12/18 15:30:34 rochecompaan
-#Fixed bugs:
-# . Fixed file creation and retrieval in same transaction in anydbm
-# backend
-# . Cgi interface now renders new issue after issue creation
-# . Could not set issue status to resolved through cgi interface
-# . Mail gateway was changing status back to 'chatting' if status was
-# omitted as an argument
-#
-#Revision 1.19 2001/12/17 03:52:48 richard
-#Implemented file store rollback. As a bonus, the hyperdb is now capable of
-#storing more than one file per node - if a property name is supplied,
-#the file is called designator.property.
-#I decided not to migrate the existing files stored over to the new naming
-#scheme - the FileClass just doesn't specify the property name.
-#
-#Revision 1.18 2001/12/16 10:53:38 richard
-#take a copy of the node dict so that the subsequent set

-#Cor blimey this anydbm/whichdb stuff is yecchy. Turns out that whichdb

-#https://sourceforge.net/tracker/index.php?func=detail&aid=491888&group_id=5470&atid=105470
-#
-#Revision 1.15 2001/12/12 02:30:51 richard
-#I fixed the problems with people whose anydbm was using the dbm module at the
-#backend. It turns out the dbm module modifies the file name to append ".db"
-#and my check to determine if we're opening an existing or new db just
-#tested os.path.exists() on the filename. Well, no longer! We now perform a
-#much better check _and_ cope with the anydbm implementation module changing
-#too!
-#I also fixed the backends __init__ so only ImportError is squashed.
-#
-#Revision 1.14 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 1.13 2001/12/02 05:06:16 richard
-#. We now use weakrefs in the Classes to keep the database reference, so
-# the close() method on the database is no longer needed.
-# I bumped the minimum python requirement up to 2.1 accordingly.
-#. #487480 ] roundup-server
-#. #487476 ] INSTALL.txt
-#
-#I also cleaned up the change message / post-edit stuff in the cgi client.
-#There's now a clearly marked "TODO: append the change note" where I believe
-#the change note should be added there. The "changes" list will obviously
-#have to be modified to be a dict of the changes, or somesuch.
-#
-#More testing needed.
-#
-#Revision 1.12 2001/12/01 07:17:50 richard
-#. We now have basic transaction support! Information is only written to
-# the database when the commit() method is called. Only the anydbm
-# backend is modified in this way - neither of the bsddb backends have been.
-# The mail, admin and cgi interfaces all use commit (except the admin tool
-# doesn't have a commit command, so interactive users can't commit...)
-#. Fixed login/registration forwarding the user to the right page (or not,
-# on a failure)
-#
-#Revision 1.11 2001/11/21 02:34:18 richard
-#Added a target version field to the extended issue schema
-#
-#Revision 1.10 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 1.9 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.
-#
