// $Log: AllUsers.php,v $
// Revision 1.18  2004/11/23 15:17:19  rurban
// better support for case_exact search (not caseexact for consistency),
// plugin args simplification:
//   handle and explode exclude and pages argument in WikiPlugin::getArgs
//     and exclude in advance (at the sql level if possible)
//   handle sortby and limit from request override in WikiPlugin::getArgs
// ListSubpages: renamed pages to maxpages
//
// Revision 1.17  2004/11/19 13:25:31  rurban
// clarify docs
//
// Revision 1.16  2004/09/25 16:37:18  rurban
// add support for all PageList options
//
// Revision 1.15  2004/07/08 13:50:33  rurban
// various unit test fixes: print error backtrace on _DEBUG_TRACE; allusers fix; new PHPWIKI_NOMAIN constant for omitting the mainloop
//
// Revision 1.14  2004/06/25 14:29:22  rurban
// WikiGroup refactoring:
//   global group attached to user, code for not_current user.
//   improved helpers for special groups (avoid double invocations)
// new experimental config option ENABLE_XHTML_XML (fails with IE, and document.write())
// fixed a XHTML validation error on userprefs.tmpl
//
// Revision 1.13  2004/06/16 10:38:59  rurban
// Disallow refernces in calls if the declaration is a reference
// ("allow_call_time_pass_reference clean").
//   PhpWiki is now allow_call_time_pass_reference = Off clean,
//   but several external libraries may not.
//   In detail these libs look to be affected (not tested):
//   * Pear_DB odbc
//   * adodb oracle
//
// Revision 1.12  2004/04/20 00:56:00  rurban
// more paging support and paging fix for shorter lists
//
// Revision 1.11  2004/03/10 13:54:54  rurban
// adodb WikiGroup fix
//
// Revision 1.10  2004/03/08 19:30:01  rurban
// fixed Theme->getButtonURL
// AllUsers uses now WikiGroup (also DB User and DB Pref users)
// PageList fix for empty pagenames
//
// Revision 1.9  2004/02/22 23:20:33  rurban
// fixed DumpHtmlToDir,
// enhanced sortby handling in PageList
//   new button_heading th style (enabled),
// added sortby and limit support to the db backends and plugins
//   for paging support (<<prev, next>> links on long lists)
//
// Revision 1.8  2004/02/17 12:11:36  rurban
// added missing 4th basepage arg at plugin->run() to almost all plugins. This caused no harm so far, because it was silently dropped on normal usage. However on plugin internal ->run invocations it failed. (InterWikiSearch, IncludeSiteMap, ...)
//
// Revision 1.7  2003/12/21 00:29:45  carstenklapp
// Minor bugfix: Fixed broken debug argument.
//
// Internal changes: Only create a DebugTimer when actually called for;
// moved debug message out of page content and into deferred page error
// notification via trigger_error. Memory management: Only include_once
// lib/PageList when absolutely necessary (at this time, this will
// probably only benefit the PluginManager as an incremental speedup &
// slightly reduced memory).
//
// Revision 1.6  2003/02/27 20:10:31  dairiki
// Disable profiling output when DEBUG is defined but false.
//
// Revision 1.5  2003/02/21 04:08:26  dairiki
// New class DebugTimer in prepend.php to help report timing.
//
// Revision 1.4  2003/01/18 21:19:25  carstenklapp
// Code cleanup:
// Reformatting; added copyleft, getVersion, getDescription
//

// Local Variables:
// mode: php
// tab-width: 8
// c-basic-offset: 4
// c-hanging-comment-ender-p: nil
// indent-tabs-mode: nil
