796 // 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.

817 // PageList enhanced and improved.
818 // fixed new WikiAdmin... plugins
819 // editpage, Theme with exp. htmlarea framework

821 // WikiUser... code with better session handling for prefs
822 // enhanced UserPreferences (again)
823 // RecentChanges for show_deleted: how should pages be deleted then?
825 // Revision 1.48 2004/02/01 09:14:11 rurban
826 // Started with Group_Ldap (not yet ready)
827 // added new _AuthInfo plugin to help in auth problems (warning: may display passwords)
828 // fixed some configurator vars
829 // renamed LDAP_AUTH_SEARCH to LDAP_BASE_DN
830 // changed PHPWIKI_VERSION from 1.3.8a to 1.3.8pre
831 // USE_DB_SESSION defaults to true on SQL
832 // changed GROUP_METHOD definition to string, not constants
833 // changed sample user DBAuthParams from UPDATE to REPLACE to be able to
834 // create users. (Not to be used with external databases generally, but
835 // with the default internal user table)
837 // fixed the IndexAsConfigProblem logic. this was flawed:
838 // scripts which are the same virtual path defined their own lib/main call
839 // (hmm, have to test this better, phpwiki.sf.net/demo works again)
841 // Revision 1.47 2004/01/27 23:23:39 rurban
842 // renamed ->Username => _userid for consistency
843 // renamed mayCheckPassword => mayCheckPass
844 // fixed recursion problem in WikiUserNew
845 // fixed bogo login (but not quite 100% ready yet, password storage)
847 // Revision 1.46 2004/01/26 09:17:48 rurban
848 // * changed stored pref representation as before.
849 // the array of objects is 1) bigger and 2)
850 // less portable. If we would import packed pref
851 // objects and the object definition was changed, PHP would fail.
852 // This doesn't happen with an simple array of non-default values.
853 // * use $prefs->retrieve and $prefs->store methods, where retrieve
854 // understands the interim format of array of objects also.
855 // * simplified $prefs->get() and fixed $prefs->set()
856 // * added $user->_userid and class '_WikiUser' portability functions
857 // * fixed $user object ->_level upgrading, mostly using sessions.
858 // this fixes yesterdays problems with loosing authorization level.
859 // * fixed WikiUserNew::checkPass to return the _level
860 // * fixed WikiUserNew::isSignedIn
861 // * added explodePageList to class PageList, support sortby arg
862 // * fixed UserPreferences for WikiUserNew
863 // * fixed WikiPlugin for empty defaults array
864 // * UnfoldSubpages: added pagename arg, renamed pages arg,
865 // removed sort arg, support sortby arg
867 // Revision 1.45 2003/12/09 20:00:43 carstenklapp
868 // Bugfix: The last BogoUserPrefs-bugfix prevented the admin from saving
869 // prefs into his own homepage, fixed broken logic. Tightened up BogoUser
870 // prefs saving ability by checking for true existance of homepage
871 // (previously a page revision of 0 also counted as valid, again due to
872 // somewhat flawed logic).
874 // Revision 1.44 2003/12/06 04:56:23 carstenklapp
875 // Security bugfix (minor): Prevent BogoUser~s from saving extraneous
876 // _pref object meta-data within locked pages.
878 // Previously, BogoUser~s who signed in with a (valid) WikiWord such as
879 // "HomePage" could actually save preferences into that page, even though
880 // it was already locked by the administrator. Thus, any subsequent
881 // WikiLink~s to that page would become prefixed with "that nice little"
882 // UserIcon, as if that page represented a valid user.
884 // Note that the admin can lock (even) non-existant pages as desired or
885 // necessary (i.e. any DB page whose revision==0), to prevent the
886 // arbitrary BogoUser from saving preference metadata into such a page;
887 // for example, the silly WikiName "@qmgi`Vcft_x|" (that is the
888 // \$examplechars presented in login.tmpl, in case it is not visible here
889 // in the CVS comments).
891 // http://phpwiki.sourceforge.net/phpwiki/
892 // %C0%F1%ED%E7%E9%E0%D6%E3%E6%F4%DF%F8%FC?action=lock
894 // To remove the prefs metadata from a page, the admin can use the
895 // EditMetaData plugin, enter pref as the key, leave the value box empty
896 // and then submit the change. For example:
898 // http://phpwiki.sourceforge.net/phpwiki/
899 // _EditMetaData?page=%C0%F1%ED%E7%E9%E0%D6%E3%E6%F4%DF%F8%FC
901 // (It seems a rethinking of WikiUserNew.php with its WikiUser and
902 // UserPreferences classes is in order. Ideally the WikiDB would
903 // transparently handle such a situation, perhaps BogoUser~s should
904 // simply be restricted to saving preferences into a cookie until his/her
905 // e-mail address has been verified.)
907 // Revision 1.43 2003/12/04 19:33:30 carstenklapp
908 // Bugfix: Under certain PhpWiki installations (such as the PhpWiki at
909 // SF), the user was unable to select a theme other than the server's
910 // default. (Use the more robust Theme::findFile instead of PHP's
911 // file_exists function to detect installed themes).
913 // Revision 1.42 2003/11/30 18:18:13 carstenklapp
914 // Minor code optimization: use include_once instead of require_once
915 // inside functions that might not always called.
917 // Revision 1.41 2003/11/21 21:32:39 carstenklapp
918 // Bugfix: When DEFAULT_LANGUAGE was not 'en', a user's language prefs
919 // would revert to 'en' when the default <system language> was selected
920 // in UserPreferences and the user saved his preferences. (Check for
921 // empty or blank language pref in sanify function of class
922 // _UserPreference_language and return DEFAULT_LANGUAGE if nothing or
923 // default selected in UserPreferences.)
925 // Revision 1.40 2003/11/21 16:54:58 carstenklapp
926 // Bugfix: login.tmpl was always displayed in English despite
927 // DEFAULT_LANGUAGE set in index.php. (Added call to
928 // update_locale(DEFAULT_LANGUAGE) before printing login form).
930 // Revision 1.39 2003/10/28 21:13:46 carstenklapp
931 // Security bug fix for admin password, submitted by Julien Charbon.
933 // Revision 1.38 2003/09/13 22:25:38 carstenklapp

939 // Revision 1.36 2003/02/21 22:50:51 dairiki
940 // Ensure that language preference is a string.
942 // Revision 1.35 2003/02/16 20:04:47 dairiki
943 // Refactor the HTTP validator generation/checking code.
945 // This also fixes a number of bugs with yesterdays validator mods.
947 // Revision 1.34 2003/02/15 02:21:54 dairiki
948 // API Change! Explicit $request argument added to contructor for WikiUser.
950 // This seemed the best way to fix a problem whereby the WikiDB
951 // was being opened twice. (Which while being merely inefficient
952 // when using an SQL backend causes hangage when using a dba backend.)
954 // Revision 1.33 2003/01/22 03:21:40 zorloc
955 // Modified WikiUser constructor to move the DB request for the homepage to
956 // the end of the logic to prevent it from being requested and then dropped.
957 // Added more phpdoc comments.
959 // Revision 1.32 2003/01/21 07:40:50 zorloc
960 // Modified WikiUser::_ok() -- Inverted the logic so the default is to return
961 // false and to return true only in the desired condition. Added phpdoc
964 // Revision 1.31 2003/01/15 05:37:20 carstenklapp
967 // Revision 1.30 2003/01/15 04:59:27 carstenklapp
968 // Bugfix: Previously stored preferences were not loading when user
969 // signed in. (Fixed... I hope.)
