- /**
- * This is a complete OOP rewrite of the old WikiUser code with various
- * configurable external authentication methods.
- *
- * There's only one entry point, the function WikiUser which returns
- * a WikiUser object, which contains the name, authlevel and user's preferences.
- * This object might get upgraded during the login step and later also.
- * There exist three preferences storage methods: cookie, homepage and db,
- * and multiple password checking methods.
- * See index.php for $USER_AUTH_ORDER[] and USER_AUTH_POLICY if
- * ALLOW_USER_PASSWORDS is defined.
- *
- * Each user object must define the two preferences methods
- * getPreferences(), setPreferences(),
- * and the following 1-4 auth methods
- * checkPass() must be defined by all classes,
- * userExists() only if USER_AUTH_POLICY'=='strict'
- * mayChangePass() only if the password is storable.
- * storePass() only if the password is storable.
- *
- * WikiUser() given no name, returns an _AnonUser (anonymous user)
- * object, who may or may not have a cookie.
- * However, if the there's a cookie with the userid or a session,
- * the user is upgraded to the matching user object.
- * Given a user name, returns a _BogoUser object, who may or may not
- * have a cookie and/or PersonalPage, one of the various _PassUser objects
- * or an _AdminUser object.
- * BTW: A BogoUser is a userid (loginname) as valid WikiWord, who might
- * have stored a password or not. If so, his account is secure, if not
- * anybody can use it, because the username is visible e.g. in RecentChanges.
- *
- * Takes care of passwords, all preference loading/storing in the
- * user's page and any cookies. lib/main.php will query the user object to
- * verify the password as appropriate.
- *
- * @author: Reini Urban (the tricky parts),
- * Carsten Klapp (started rolling the ball)
- *
- * Random architectural notes, sorted by date:
- * 2004-01-25 rurban
- * Test it by defining ENABLE_USER_NEW in config/config.ini
- * 1) Now a ForbiddenUser is returned instead of false.
- * 2) Previously ALLOW_ANON_USER = false meant that anon users cannot edit,
- * but may browse. Now with ALLOW_ANON_USER = false he may not browse,
- * which is needed to disable browse PagePermissions.
- * I added now ALLOW_ANON_EDIT = true to makes things clear.
- * (which replaces REQUIRE_SIGNIN_BEFORE_EDIT)
- * 2004-02-27 rurban:
- * 3) Removed pear prepare. Performance hog, and using integers as
- * handler doesn't help. Do simple sprintf as with adodb. And a prepare
- * in the object init is no advantage, because in the init loop a lot of
- * objects are tried, but not used.
- * 4) Already gotten prefs are passed to the next object to avoid
- * duplicate getPreferences() calls.
- * 2004-03-18 rurban
- * 5) Major php-5 problem: $this re-assignment is disallowed by the parser
- * So we cannot just discrimate with
- * if (!check_php_version(5))
- * $this = $user;
- * A /php5-patch.php is provided, which patches the src automatically
- * for php4 and php5. Default is php4.
- * Update: not needed anymore. we use eval to fool the load-time syntax checker.
- * 2004-03-24 rurban
- * 6) enforced new cookie policy: prefs don't get stored in cookies
- * anymore, only in homepage and/or database, but always in the
- * current session. old pref cookies will get deleted.
- * 2004-04-04 rurban
- * 7) Certain themes should be able to extend the predefined list
- * of preferences. Display/editing is done in the theme specific userprefs.tmpl,
- * but storage must be extended to the Get/SetPreferences methods.
- * <theme>/themeinfo.php must provide CustomUserPreferences:
- * A list of name => _UserPreference class pairs.

- // 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.
