From e2dd15625f158c7f7d8f5ceec14f09e85dd8e2b6 Mon Sep 17 00:00:00 2001 From: Diva Canto Date: Fri, 9 Jan 2015 08:31:56 -0800 Subject: Added GetDisplayNames capability. For now, we don't actually use display names, and this cap returns the regular name. But this moves the server side into the newer, preferred, protocol used by the viewer for fetching the names of agents in the scene given their UUIDs. (the old protocol is via UDP). This works fine in my limited tests, but could use further testing by others. --- .../GetDisplayNames/GetDisplayNamesHandler.cs | 120 +++++++++++++++++++++ .../GetDisplayNamesServerConnector.cs | 71 ++++++++++++ 2 files changed, 191 insertions(+) create mode 100644 OpenSim/Capabilities/Handlers/GetDisplayNames/GetDisplayNamesHandler.cs create mode 100644 OpenSim/Capabilities/Handlers/GetDisplayNames/GetDisplayNamesServerConnector.cs (limited to 'OpenSim/Capabilities/Handlers') diff --git a/OpenSim/Capabilities/Handlers/GetDisplayNames/GetDisplayNamesHandler.cs b/OpenSim/Capabilities/Handlers/GetDisplayNames/GetDisplayNamesHandler.cs new file mode 100644 index 0000000..0353d9d --- /dev/null +++ b/OpenSim/Capabilities/Handlers/GetDisplayNames/GetDisplayNamesHandler.cs @@ -0,0 +1,120 @@ +/* + * 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.
