730 // Started with Group_Ldap (not yet ready)
731 // added new _AuthInfo plugin to help in auth problems (warning: may display passwords)
732 // fixed some configurator vars
733 // renamed LDAP_AUTH_SEARCH to LDAP_BASE_DN
734 // changed PHPWIKI_VERSION from 1.3.8a to 1.3.8pre
735 // USE_DB_SESSION defaults to true on SQL
736 // changed GROUP_METHOD definition to string, not constants
737 // changed sample user DBAuthParams from UPDATE to REPLACE to be able to
738 // create users. (Not to be used with external databases generally, but
739 // with the default internal user table)
741 // fixed the IndexAsConfigProblem logic. this was flawed:

743 // (hmm, have to test this better, phpwiki.sf.net/demo works again)
745 // Revision 1.47 2004/01/27 23:23:39 rurban

749 // fixed bogo login (but not quite 100% ready yet, password storage)
751 // Revision 1.46 2004/01/26 09:17:48 rurban
752 // * changed stored pref representation as before.
753 // the array of objects is 1) bigger and 2)

756 // This doesn't happen with an simple array of non-default values.

759 // * simplified $prefs->get() and fixed $prefs->set()
760 // * added $user->_userid and class '_WikiUser' portability functions
761 // * fixed $user object ->_level upgrading, mostly using sessions.
762 // this fixes yesterdays problems with loosing authorization level.
763 // * fixed WikiUserNew::checkPass to return the _level
764 // * fixed WikiUserNew::isSignedIn
765 // * added explodePageList to class PageList, support sortby arg
766 // * fixed UserPreferences for WikiUserNew
767 // * fixed WikiPlugin for empty defaults array
768 // * UnfoldSubpages: added pagename arg, renamed pages arg,

778 // Revision 1.44 2003/12/06 04:56:23 carstenklapp
779 // Security bugfix (minor): Prevent BogoUser~s from saving extraneous
780 // _pref object meta-data within locked pages.
782 // Previously, BogoUser~s who signed in with a (valid) WikiWord such as
783 // "HomePage" could actually save preferences into that page, even though
784 // it was already locked by the administrator. Thus, any subsequent
785 // WikiLink~s to that page would become prefixed with "that nice little"
786 // UserIcon, as if that page represented a valid user.
788 // Note that the admin can lock (even) non-existant pages as desired or
789 // necessary (i.e. any DB page whose revision==0), to prevent the
790 // arbitrary BogoUser from saving preference metadata into such a page;
791 // for example, the silly WikiName "@qmgi`Vcft_x|" (that is the
792 // \$examplechars presented in login.tmpl, in case it is not visible here
793 // in the CVS comments).

796 // %C0%F1%ED%E7%E9%E0%D6%E3%E6%F4%DF%F8%FC?action=lock
798 // To remove the prefs metadata from a page, the admin can use the
799 // EditMetaData plugin, enter pref as the key, leave the value box empty
800 // and then submit the change. For example:
802 // http://phpwiki.sourceforge.net/phpwiki/
803 // _EditMetaData?page=%C0%F1%ED%E7%E9%E0%D6%E3%E6%F4%DF%F8%FC
805 // (It seems a rethinking of WikiUserNew.php with its WikiUser and
806 // UserPreferences classes is in order. Ideally the WikiDB would
807 // transparently handle such a situation, perhaps BogoUser~s should
808 // simply be restricted to saving preferences into a cookie until his/her
809 // e-mail address has been verified.)
811 // Revision 1.43 2003/12/04 19:33:30 carstenklapp
812 // Bugfix: Under certain PhpWiki installations (such as the PhpWiki at
813 // SF), the user was unable to select a theme other than the server's
814 // default. (Use the more robust Theme::findFile instead of PHP's
815 // file_exists function to detect installed themes).
817 // Revision 1.42 2003/11/30 18:18:13 carstenklapp
818 // Minor code optimization: use include_once instead of require_once
819 // inside functions that might not always called.
821 // Revision 1.41 2003/11/21 21:32:39 carstenklapp
822 // Bugfix: When DEFAULT_LANGUAGE was not 'en', a user's language prefs
823 // would revert to 'en' when the default <system language> was selected
824 // in UserPreferences and the user saved his preferences. (Check for
825 // empty or blank language pref in sanify function of class
826 // _UserPreference_language and return DEFAULT_LANGUAGE if nothing or
827 // default selected in UserPreferences.)
829 // Revision 1.40 2003/11/21 16:54:58 carstenklapp
830 // Bugfix: login.tmpl was always displayed in English despite
831 // DEFAULT_LANGUAGE set in index.php. (Added call to
832 // update_locale(DEFAULT_LANGUAGE) before printing login form).
834 // Revision 1.39 2003/10/28 21:13:46 carstenklapp
835 // Security bug fix for admin password, submitted by Julien Charbon.
837 // Revision 1.38 2003/09/13 22:25:38 carstenklapp
838 // Hook for new user preference 'noLinkIcons'.
840 // Revision 1.37 2003/02/22 20:49:55 dairiki
841 // Fixes for "Call-time pass by reference has been deprecated" errors.
843 // Revision 1.36 2003/02/21 22:50:51 dairiki
844 // Ensure that language preference is a string.
846 // Revision 1.35 2003/02/16 20:04:47 dairiki
847 // Refactor the HTTP validator generation/checking code.
849 // This also fixes a number of bugs with yesterdays validator mods.
851 // Revision 1.34 2003/02/15 02:21:54 dairiki
852 // API Change! Explicit $request argument added to contructor for WikiUser.
854 // This seemed the best way to fix a problem whereby the WikiDB
855 // was being opened twice. (Which while being merely inefficient
856 // when using an SQL backend causes hangage when using a dba backend.)
858 // Revision 1.33 2003/01/22 03:21:40 zorloc
859 // Modified WikiUser constructor to move the DB request for the homepage to
860 // the end of the logic to prevent it from being requested and then dropped.
861 // Added more phpdoc comments.
863 // Revision 1.32 2003/01/21 07:40:50 zorloc
864 // Modified WikiUser::_ok() -- Inverted the logic so the default is to return
865 // false and to return true only in the desired condition. Added phpdoc
868 // Revision 1.31 2003/01/15 05:37:20 carstenklapp
871 // Revision 1.30 2003/01/15 04:59:27 carstenklapp
872 // Bugfix: Previously stored preferences were not loading when user
873 // signed in. (Fixed... I hope.)
