From b6076d7b337dc087807e56cdbe74ef47dc1b66b3 Mon Sep 17 00:00:00 2001 From: Justin Clark-Casey (justincc) Date: Tue, 8 Jun 2010 15:07:57 +0100 Subject: Reduce number of full updates sent on region crossing for attachments/huds to 1 from 3 This is one step towards reducing hud glitches on region crossing, since the viewer fails to display prims if it receives child full updates before the root prim full update This commit also introduces a mechanism in LLClientView to stop child attachment updates ever going out before the root one This is a very temporary mechanism and will be commented out when the next step of the fix (to give root prims higher udpate priority) is committed This code is a foreport from the equivalent changes in 0.6.9-post-fixes --- .../Region/ClientStack/LindenUDP/LLClientView.cs | 43 +++++++++++++++++++++- OpenSim/Region/Framework/Scenes/Scene.cs | 42 ++++++++++++++++++--- OpenSim/Region/Framework/Scenes/SceneGraph.cs | 10 +++-- .../Region/Framework/Scenes/SceneObjectGroup.cs | 3 +- 4 files changed, 86 insertions(+), 12 deletions(-) (limited to 'OpenSim/Region') diff --git a/OpenSim/Region/ClientStack/LindenUDP/LLClientView.cs b/OpenSim/Region/ClientStack/LindenUDP/LLClientView.cs index a516a54..0e58986 100644 --- a/OpenSim/Region/ClientStack/LindenUDP/LLClientView.cs +++ b/OpenSim/Region/ClientStack/LindenUDP/LLClientView.cs @@ -331,6 +331,8 @@ namespace OpenSim.Region.ClientStack.LindenUDP /// protected HashSet m_killRecord;
