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

2255 // 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.
