1837 // * added global ->prepare (not yet used) with smart user/pref/member table prefixing.
1838 // * force init of authdbh in the 2 db classes
1840 // * fixed session handling (not triple auth request anymore)
1841 // * don't store cookie prefs with sessions
1842 // stdlib: global obj2hash helper from _AuthInfo, also needed for PagePerm
1844 // Revision 1.111 2004/02/07 10:41:25 rurban
1845 // fixed auth from session (still double code but works)
1847 // fixed DbPassUser upgrade and policy=old
1850 // Revision 1.110 2004/02/03 09:45:39 rurban
1851 // LDAP cleanup, start of new Pref classes
1853 // Revision 1.109 2004/01/30 19:57:58 rurban
1854 // fixed DBAuthParams['pref_select']: wrong _auth_dbi object used.
1856 // Revision 1.108 2004/01/28 14:34:14 rurban
1857 // session table takes the common prefix
1858 // + various minor stuff
1859 // reallow password changing
1861 // Revision 1.107 2004/01/27 23:23:39 rurban
1862 // renamed ->Username => _userid for consistency
1863 // renamed mayCheckPassword => mayCheckPass
1864 // fixed recursion problem in WikiUserNew
1865 // fixed bogo login (but not quite 100% ready yet, password storage)
1867 // Revision 1.106 2004/01/26 09:17:49 rurban
1868 // * changed stored pref representation as before.
1869 // the array of objects is 1) bigger and 2)
1870 // less portable. If we would import packed pref
1871 // objects and the object definition was changed, PHP would fail.
1872 // This doesn't happen with an simple array of non-default values.
1873 // * use $prefs->retrieve and $prefs->store methods, where retrieve
1874 // understands the interim format of array of objects also.
1875 // * simplified $prefs->get() and fixed $prefs->set()
1876 // * added $user->_userid and class '_WikiUser' portability functions
1877 // * fixed $user object ->_level upgrading, mostly using sessions.
1878 // this fixes yesterdays problems with loosing authorization level.
1879 // * fixed WikiUserNew::checkPass to return the _level
1880 // * fixed WikiUserNew::isSignedIn
1881 // * added explodePageList to class PageList, support sortby arg
1882 // * fixed UserPreferences for WikiUserNew
1883 // * fixed WikiPlugin for empty defaults array
1884 // * UnfoldSubpages: added pagename arg, renamed pages arg,
1885 // removed sort arg, support sortby arg
1887 // Revision 1.105 2004/01/25 03:57:15 rurban
1888 // WikiUserNew support (temp. ENABLE_USER_NEW constant)

1891 // Bugfix: Try to defer OS errors about session.save_path and ACCESS_LOG,
1892 // so they don't prevent IE from partially (or not at all) rendering the
1893 // page. This should help a little for the IE user who encounters trouble
1894 // when setting up a new PhpWiki for the first time.
1896 // Revision 1.103 2003/12/02 00:10:00 carstenklapp
1897 // Bugfix: Ongoing work to untangle UserPreferences/WikiUser/request code
1898 // mess: UserPreferences should take effect immediately now upon signing
1901 // Revision 1.102 2003/11/25 22:55:32 carstenklapp
1902 // Localization bugfix: For wikis where English is not the default system
1903 // language, make sure that the authority error message (i.e. "You must
1904 // sign in to edit pages in this wiki" etc.) is displayed in the wiki's
1905 // default language. Previously it would always display in English.
1906 // (Added call to update_locale() before displaying any messages prior to
1907 // the login prompt.)
1909 // Revision 1.101 2003/11/25 21:49:44 carstenklapp
1910 // Bugfix: For a non-english wiki or when the user's preference is not
1911 // english, the wiki would always use the english ActionPage first if it
1912 // was present rather than the appropriate localised variant. (PhpWikis
1913 // running only in english or Wikis running ONLY without any english
1914 // ActionPages would not notice this bug, only when both english and
1915 // localised ActionPages were in the DB.) Now we check for the localised
