784 // Fixes permission failure issues. With PagePermissions and Disabled Actions when user did not have permission WIKIAUTH_FORBIDDEN was returned. In WikiUser this was ok because WIKIAUTH_FORBIDDEN had a value of 11 -- thus no user could perform that action. But WikiUserNew has a WIKIAUTH_FORBIDDEN value of -1 -- thus a user without sufficent permission to do anything. The solution is a new high value permission level (WIKIAUTH_UNOBTAINABLE) to be the default level for access failure.

805 // PageList enhanced and improved.
806 // fixed new WikiAdmin... plugins
807 // editpage, Theme with exp. htmlarea framework
808 // (htmlarea yet committed, this is really questionable)
809 // WikiUser... code with better session handling for prefs
810 // enhanced UserPreferences (again)
811 // RecentChanges for show_deleted: how should pages be deleted then?
813 // Revision 1.48 2004/02/01 09:14:11 rurban
814 // Started with Group_Ldap (not yet ready)
815 // added new _AuthInfo plugin to help in auth problems (warning: may display passwords)
816 // fixed some configurator vars
817 // renamed LDAP_AUTH_SEARCH to LDAP_BASE_DN
818 // changed PHPWIKI_VERSION from 1.3.8a to 1.3.8pre
819 // USE_DB_SESSION defaults to true on SQL
820 // changed GROUP_METHOD definition to string, not constants
821 // changed sample user DBAuthParams from UPDATE to REPLACE to be able to
822 // create users. (Not to be used with external databases generally, but
823 // with the default internal user table)
825 // fixed the IndexAsConfigProblem logic. this was flawed:
826 // scripts which are the same virtual path defined their own lib/main call
827 // (hmm, have to test this better, phpwiki.sf.net/demo works again)
829 // Revision 1.47 2004/01/27 23:23:39 rurban
830 // renamed ->Username => _userid for consistency
831 // renamed mayCheckPassword => mayCheckPass
832 // fixed recursion problem in WikiUserNew
833 // fixed bogo login (but not quite 100% ready yet, password storage)
835 // Revision 1.46 2004/01/26 09:17:48 rurban
836 // * changed stored pref representation as before.
837 // the array of objects is 1) bigger and 2)
838 // less portable. If we would import packed pref
839 // objects and the object definition was changed, PHP would fail.
840 // This doesn't happen with an simple array of non-default values.
841 // * use $prefs->retrieve and $prefs->store methods, where retrieve
842 // understands the interim format of array of objects also.
843 // * simplified $prefs->get() and fixed $prefs->set()
844 // * added $user->_userid and class '_WikiUser' portability functions
845 // * fixed $user object ->_level upgrading, mostly using sessions.
846 // this fixes yesterdays problems with loosing authorization level.
847 // * fixed WikiUserNew::checkPass to return the _level
848 // * fixed WikiUserNew::isSignedIn
849 // * added explodePageList to class PageList, support sortby arg
850 // * fixed UserPreferences for WikiUserNew
851 // * fixed WikiPlugin for empty defaults array
852 // * UnfoldSubpages: added pagename arg, renamed pages arg,
853 // removed sort arg, support sortby arg
855 // Revision 1.45 2003/12/09 20:00:43 carstenklapp
856 // Bugfix: The last BogoUserPrefs-bugfix prevented the admin from saving
857 // prefs into his own homepage, fixed broken logic. Tightened up BogoUser
858 // prefs saving ability by checking for true existance of homepage
859 // (previously a page revision of 0 also counted as valid, again due to
860 // somewhat flawed logic).
862 // Revision 1.44 2003/12/06 04:56:23 carstenklapp
863 // Security bugfix (minor): Prevent BogoUser~s from saving extraneous
864 // _pref object meta-data within locked pages.
866 // Previously, BogoUser~s who signed in with a (valid) WikiWord such as
867 // "HomePage" could actually save preferences into that page, even though
868 // it was already locked by the administrator. Thus, any subsequent
869 // WikiLink~s to that page would become prefixed with "that nice little"
870 // UserIcon, as if that page represented a valid user.
872 // Note that the admin can lock (even) non-existant pages as desired or
873 // necessary (i.e. any DB page whose revision==0), to prevent the
874 // arbitrary BogoUser from saving preference metadata into such a page;
875 // for example, the silly WikiName "@qmgi`Vcft_x|" (that is the
876 // \$examplechars presented in login.tmpl, in case it is not visible here
877 // in the CVS comments).
879 // http://phpwiki.sourceforge.net/phpwiki/
880 // %C0%F1%ED%E7%E9%E0%D6%E3%E6%F4%DF%F8%FC?action=lock
882 // To remove the prefs metadata from a page, the admin can use the
883 // EditMetaData plugin, enter pref as the key, leave the value box empty
884 // and then submit the change. For example:
886 // http://phpwiki.sourceforge.net/phpwiki/
887 // _EditMetaData?page=%C0%F1%ED%E7%E9%E0%D6%E3%E6%F4%DF%F8%FC
889 // (It seems a rethinking of WikiUserNew.php with its WikiUser and
890 // UserPreferences classes is in order. Ideally the WikiDB would
891 // transparently handle such a situation, perhaps BogoUser~s should
892 // simply be restricted to saving preferences into a cookie until his/her
893 // e-mail address has been verified.)
895 // Revision 1.43 2003/12/04 19:33:30 carstenklapp
896 // Bugfix: Under certain PhpWiki installations (such as the PhpWiki at
897 // SF), the user was unable to select a theme other than the server's
898 // default. (Use the more robust Theme::findFile instead of PHP's
899 // file_exists function to detect installed themes).
901 // Revision 1.42 2003/11/30 18:18:13 carstenklapp
902 // Minor code optimization: use include_once instead of require_once
903 // inside functions that might not always called.
905 // Revision 1.41 2003/11/21 21:32:39 carstenklapp
906 // Bugfix: When DEFAULT_LANGUAGE was not 'en', a user's language prefs
907 // would revert to 'en' when the default <system language> was selected
908 // in UserPreferences and the user saved his preferences. (Check for
909 // empty or blank language pref in sanify function of class
910 // _UserPreference_language and return DEFAULT_LANGUAGE if nothing or
911 // default selected in UserPreferences.)
913 // Revision 1.40 2003/11/21 16:54:58 carstenklapp
914 // Bugfix: login.tmpl was always displayed in English despite
915 // DEFAULT_LANGUAGE set in index.php. (Added call to
916 // update_locale(DEFAULT_LANGUAGE) before printing login form).
918 // Revision 1.39 2003/10/28 21:13:46 carstenklapp
919 // Security bug fix for admin password, submitted by Julien Charbon.
921 // Revision 1.38 2003/09/13 22:25:38 carstenklapp
922 // Hook for new user preference 'noLinkIcons'.
924 // Revision 1.37 2003/02/22 20:49:55 dairiki
925 // Fixes for "Call-time pass by reference has been deprecated" errors.
927 // Revision 1.36 2003/02/21 22:50:51 dairiki
928 // Ensure that language preference is a string.
930 // Revision 1.35 2003/02/16 20:04:47 dairiki
931 // Refactor the HTTP validator generation/checking code.
933 // This also fixes a number of bugs with yesterdays validator mods.
935 // Revision 1.34 2003/02/15 02:21:54 dairiki
936 // API Change! Explicit $request argument added to contructor for WikiUser.
938 // This seemed the best way to fix a problem whereby the WikiDB
939 // was being opened twice. (Which while being merely inefficient
940 // when using an SQL backend causes hangage when using a dba backend.)
942 // Revision 1.33 2003/01/22 03:21:40 zorloc
943 // Modified WikiUser constructor to move the DB request for the homepage to
944 // the end of the logic to prevent it from being requested and then dropped.
945 // Added more phpdoc comments.
947 // Revision 1.32 2003/01/21 07:40:50 zorloc
948 // Modified WikiUser::_ok() -- Inverted the logic so the default is to return
949 // false and to return true only in the desired condition. Added phpdoc
952 // Revision 1.31 2003/01/15 05:37:20 carstenklapp
955 // Revision 1.30 2003/01/15 04:59:27 carstenklapp
956 // Bugfix: Previously stored preferences were not loading when user
957 // signed in. (Fixed... I hope.)
