Replaces the contrived concept of storing user's home and position info in the presence service. WARNING: I violated a taboo by deleting 2 migration files and simplifying the original table creation for Presence. This should not cause any problems to anyone, though. Things will work with the new simplified table, as well as with the previous contrived one. If there are any problems, solving them is as easy as dropping the presence table and deleting its row in the migrations table. The presence info only exists during a user's session anyway. BTW, the Meshing files want to be committed too -- EOFs. --- OpenSim/Region/Physics/Meshing/SculptMap.cs | 352 ++++++++++++++-------------- 1 file changed, 176 insertions(+), 176 deletions(-) (limited to 'OpenSim/Region/Physics/Meshing/SculptMap.cs') diff --git a/OpenSim/Region/Physics/Meshing/SculptMap.cs b/OpenSim/Region/Physics/Meshing/SculptMap.cs index 4906cf6..d2d71de 100644 --- a/OpenSim/Region/Physics/Meshing/SculptMap.cs +++ b/OpenSim/Region/Physics/Meshing/SculptMap.cs @@ -1,176 +1,176 @@ -/* - * Copyright (c) Contributors - * 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.
