In order to configure the wiki you have to make the config subdirectory
writable by the web server. Once configuration is done you'll move the created
LocalSettings.php to the parent directory, and for added safety you can
then remove the config subdirectory entirely.
To make the directory writable on a Unix/Linux system:
cd /path/to/wiki
chmod a+w config
" );
}
require_once( "install-utils.inc" );
require_once( "maintenance/updaters.inc" );
class ConfigData {
function getEncoded( $data ) {
# removing latin1 support, no need...
return $data;
}
function getSitename() { return $this->getEncoded( $this->Sitename ); }
function getSysopName() { return $this->getEncoded( $this->SysopName ); }
function getSysopPass() { return $this->getEncoded( $this->SysopPass ); }
}
