From 90262d40929ab0bdf6888861608a0e712b793f48 Mon Sep 17 00:00:00 2001 From: Melanie Date: Fri, 4 Sep 2009 00:23:26 +0100 Subject: Add the user authentication data adapter. This is meant to use a new table schema, but can read the old ones for compatibility. It should not be used to write to the old tables unless you know what you're doing! This is untested and will probably not work. --- OpenSim/Data/IAuthenticationData.cs | 52 +++++++++ OpenSim/Data/MySQL/MySQLAuthenticationData.cs | 146 ++++++++++++++++++++++++++ OpenSim/Data/MySQL/MySQLFramework.cs | 115 ++++++++++++++++++++ 3 files changed, 313 insertions(+) create mode 100644 OpenSim/Data/IAuthenticationData.cs create mode 100644 OpenSim/Data/MySQL/MySQLAuthenticationData.cs create mode 100644 OpenSim/Data/MySQL/MySQLFramework.cs (limited to 'OpenSim') diff --git a/OpenSim/Data/IAuthenticationData.cs b/OpenSim/Data/IAuthenticationData.cs new file mode 100644 index 0000000..f848716 --- /dev/null +++ b/OpenSim/Data/IAuthenticationData.cs @@ -0,0 +1,52 @@ +/* + * Copyright (c) Contributors, http://opensimulator.org/ + * See CONTRIBUTORS.TXT for a full list of copyright holders. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are met: + * * Redistributions of source code must retain the above copyright + * notice, this list of conditions and the following disclaimer. + * * Redistributions in binary form must reproduce the above copyright + * notice, this list of conditions and the following disclaimer in the + * documentation and/or other materials provided with the distribution. + * * Neither the name of the OpenSimulator Project nor the + * names of its contributors may be used to endorse or promote products + * derived from this software without specific prior written permission. + * + * THIS SOFTWARE IS PROVIDED BY THE DEVELOPERS ``AS IS'' AND ANY + * EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED + * WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE + * DISCLAIMED.
