From 319ebaca06db3d4a38beff74725d321b7c836157 Mon Sep 17 00:00:00 2001 From: Justin Clark-Casey (justincc) Date: Tue, 23 Oct 2012 02:44:15 +0100 Subject: Make it possible to turn the base UDP object packet pools on and off whilst running via the "debug lludp pool " console command. For debug purposes. This does not currently apply to the higher LLUDP packetpool. --- OpenSim/Framework/Monitoring/StatsManager.cs | 14 +-- .../Region/ClientStack/Linden/UDP/LLUDPServer.cs | 103 +++++++++++++++++---- .../ClientStack/Linden/UDP/OpenSimUDPBase.cs | 66 ++++++++----- 3 files changed, 132 insertions(+), 51 deletions(-) diff --git a/OpenSim/Framework/Monitoring/StatsManager.cs b/OpenSim/Framework/Monitoring/StatsManager.cs index 116b2c0..4844336 100644 --- a/OpenSim/Framework/Monitoring/StatsManager.cs +++ b/OpenSim/Framework/Monitoring/StatsManager.cs @@ -207,7 +207,7 @@ namespace OpenSim.Framework.Monitoring return false; newContainer = new Dictionary(container); - newContainer.Remove(stat.UniqueName); + newContainer.Remove(stat.ShortName); newCategory = new Dictionary>(category); newCategory.Remove(stat.Container); @@ -279,11 +279,6 @@ namespace OpenSim.Framework.Monitoring public class Stat { /// - /// Unique stat name used for indexing.
