+# Revision 1.46 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 1.45 2001/12/20 15:43:01 rochecompaan
+# Features added:
+# . Multilink properties are now displayed as comma separated values in
+# a textbox
+# . The add user link is now only visible to the admin user
+# . Modified the mail gateway to reject submissions from unknown
+# addresses if ANONYMOUS_ACCESS is denied
+#
+# Revision 1.44 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 1.43 2001/12/15 19:39:01 rochecompaan
+# Oops.
+#
+# Revision 1.42 2001/12/15 19:24:39 rochecompaan
+# . Modified cgi interface to change properties only once all changes are
+# collected, files created and messages generated.
+# . Moved generation of change note to nosyreactors.
+# . We now check for changes to "assignedto" to ensure it's added to the
+# nosy list.
+#
+# Revision 1.41 2001/12/10 00:57:38 richard
+# From CHANGES:
+# . Added the "display" command to the admin tool - displays a node's values
+# . #489760 ] [issue] only subject
+# . fixed the doc/index.html to include the quoting in the mail alias.
+#
+# Also:
+# . fixed roundup-admin so it works with transactions
+# . disabled the back_anydbm module if anydbm tries to use dumbdbm
+#
+# Revision 1.40 2001/12/05 14:26:44 rochecompaan
+# Removed generation of change note from "sendmessage" in roundupdb.py.
+# The change note is now generated when the message is created.
+#
+# Revision 1.39 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 1.38 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 1.37 2001/11/28 21:55:35 richard
+# . login_action and newuser_action return values were being ignored
+# . Woohoo! Found that bloody re-login bug that was killing the mail
+# gateway.
+# (also a minor cleanup in hyperdb)
+#
+# Revision 1.36 2001/11/26 22:55:56 richard
+# Feature:
+# . Added INSTANCE_NAME to configuration - used in web and email to identify
+# the instance.
+# . Added EMAIL_SIGNATURE_POSITION to indicate where to place the roundup
+# signature info in e-mails.
+# . Some more flexibility in the mail gateway and more error handling.
+# . Login now takes you to the page you back to the were denied access to.
+#
+# Fixed:
+# . Lots of bugs, thanks Roché and others on the devel mailing list!
