39 A note about login

43 are two levels of anonymous use. If there is no 'anonymous' user, there
44 is no login at all and the database is opened in read-only mode. If the
45 'anonymous' user exists, the user is logged in using that user (though
46 there is no cookie). This allows them to modify the database, and all

1656 # Fixed some problems with user editing
1657 #
1658 # Revision 1.80 2001/12/12 23:27:14 richard
1659 # Added a Zope frontend for roundup.
1660 #
1661 # Revision 1.79 2001/12/10 22:20:01 richard
1662 # Enabled transaction support in the bsddb backend. It uses the anydbm code
1663 # where possible, only replacing methods where the db is opened (it uses the
1664 # btree opener specifically.)
1665 # Also cleaned up some change note generation.
1666 # Made the backends package work with pydoc too.
1667 #
1668 # Revision 1.78 2001/12/07 05:59:27 rochecompaan
1669 # Fixed small bug that prevented adding issues through the web.

1671 # Revision 1.77 2001/12/06 22:48:29 richard
1672 # files multilink was being nuked in post_edit_node
1673 #
1674 # Revision 1.76 2001/12/05 14:26:44 rochecompaan
1675 # Removed generation of change note from "sendmessage" in roundupdb.py.
1676 # The change note is now generated when the message is created.
1677 #
1678 # Revision 1.75 2001/12/04 01:25:08 richard
1679 # Added some rollbacks where we were catching exceptions that would otherwise
1680 # have stopped committing.
1681 #
1682 # Revision 1.74 2001/12/02 05:06:16 richard
1683 # . We now use weakrefs in the Classes to keep the database reference, so
1684 # the close() method on the database is no longer needed.
1685 # I bumped the minimum python requirement up to 2.1 accordingly.
1686 # . #487480 ] roundup-server
1687 # . #487476 ] INSTALL.txt
1688 #
1689 # I also cleaned up the change message / post-edit stuff in the cgi client.
1690 # There's now a clearly marked "TODO: append the change note" where I believe
1691 # the change note should be added there. The "changes" list will obviously
1692 # have to be modified to be a dict of the changes, or somesuch.
1693 #
1694 # More testing needed.
1695 #
1696 # Revision 1.73 2001/12/01 07:17:50 richard
1697 # . We now have basic transaction support! Information is only written to
1698 # the database when the commit() method is called. Only the anydbm
1699 # backend is modified in this way - neither of the bsddb backends have been.
1700 # The mail, admin and cgi interfaces all use commit (except the admin tool
1701 # doesn't have a commit command, so interactive users can't commit...)
1702 # . Fixed login/registration forwarding the user to the right page (or not,
1703 # on a failure)
1704 #
1705 # Revision 1.72 2001/11/30 20:47:58 rochecompaan
1706 # Links in page header are now consistent with default sort order.
1707 #
1708 # Fixed bugs:
1709 # - When login failed the list of issues were still rendered.
1710 # - User was redirected to index page and not to his destination url
1711 # if his first login attempt failed.
1712 #
1713 # Revision 1.71 2001/11/30 20:28:10 rochecompaan
1714 # Property changes are now completely traceable, whether changes are
1715 # made through the web or by email
1716 #
1717 # Revision 1.70 2001/11/30 00:06:29 richard
1718 # Converted roundup/cgi_client.py to use _()
1719 # Added the status file, I18N_PROGRESS.txt
1720 #
1721 # Revision 1.69 2001/11/29 23:19:51 richard
1722 # Removed the "This issue has been edited through the web" when a valid
1723 # change note is supplied.

1728 # Revision 1.67 2001/11/28 21:55:35 richard
1729 # . login_action and newuser_action return values were being ignored

1731 # gateway.

1744 # Feature:

1746 # the instance.
1747 # . Added EMAIL_SIGNATURE_POSITION to indicate where to place the roundup
1748 # signature info in e-mails.
1749 # . Some more flexibility in the mail gateway and more error handling.

1753 # . Lots of bugs, thanks Roché and others on the devel mailing list!
