From a040008cb956f4e99bc87a006b51925966443d63 Mon Sep 17 00:00:00 2001 From: Tedd Hansen Date: Fri, 22 Feb 2008 12:50:24 +0000 Subject: From this commit and a few hours into the future ScriptEngine will be unstable: * Speeding up ScriptEngine shutdown * Sharing threads so that minimum total thread count for any amount of regions will be 2. (1 maintenance, 1 script execution) You can choose more script exec threads if you want of course. In this commit: Sharing maintenance thread between all regions. --- .../Common/ScriptEngineBase/EventQueueManager.cs | 18 +++--- .../Common/ScriptEngineBase/MaintenanceThread.cs | 71 ++++++++++++---------- .../Common/ScriptEngineBase/ScriptEngine.cs | 26 ++++---- .../Common/ScriptEngineBase/ScriptManager.cs | 49 +++++++-------- .../iScriptEngineFunctionModule.cs | 2 +- 5 files changed, 87 insertions(+), 79 deletions(-) (limited to 'OpenSim/Region/ScriptEngine/Common/ScriptEngineBase') diff --git a/OpenSim/Region/ScriptEngine/Common/ScriptEngineBase/EventQueueManager.cs b/OpenSim/Region/ScriptEngine/Common/ScriptEngineBase/EventQueueManager.cs index aa7e3e9..e3d448c 100644 --- a/OpenSim/Region/ScriptEngine/Common/ScriptEngineBase/EventQueueManager.cs +++ b/OpenSim/Region/ScriptEngine/Common/ScriptEngineBase/EventQueueManager.cs @@ -452,14 +452,14 @@ namespace OpenSim.Region.ScriptEngine.Common.ScriptEngineBase } #endregion - /// - /// If set to true then threads and stuff should try to make a graceful exit - /// - public bool PleaseShutdown - { - get { return _PleaseShutdown; } - set { _PleaseShutdown = value; } - } - private bool _PleaseShutdown = false; + ///// + ///// If set to true then threads and stuff should try to make a graceful exit + ///// + //public bool PleaseShutdown + //{ + // get { return _PleaseShutdown; } + // set { _PleaseShutdown = value; } + //} + //private bool _PleaseShutdown = false; } } diff --git a/OpenSim/Region/ScriptEngine/Common/ScriptEngineBase/MaintenanceThread.cs b/OpenSim/Region/ScriptEngine/Common/ScriptEngineBase/MaintenanceThread.cs index f959a5b..1a5cca1 100644 --- a/OpenSim/Region/ScriptEngine/Common/ScriptEngineBase/MaintenanceThread.cs +++ b/OpenSim/Region/ScriptEngine/Common/ScriptEngineBase/MaintenanceThread.cs @@ -38,12 +38,12 @@ namespace OpenSim.Region.ScriptEngine.Common.ScriptEngineBase /// public class MaintenanceThread : iScriptEngineFunctionModule { - public ScriptEngine m_ScriptEngine; + //public ScriptEngine m_ScriptEngine; private int MaintenanceLoopms; - public MaintenanceThread(ScriptEngine _ScriptEngine) + public MaintenanceThread() { - m_ScriptEngine = _ScriptEngine; + //m_ScriptEngine = _ScriptEngine; ReadConfig(); @@ -95,9 +95,9 @@ namespace OpenSim.Region.ScriptEngine.Common.ScriptEngineBase try { if (MaintenanceThreadThread != null && MaintenanceThreadThread.IsAlive) - { - MaintenanceThreadThread.Abort(); - } + { + MaintenanceThreadThread.Abort(); + } } catch (Exception ex) { @@ -105,14 +105,15 @@ namespace OpenSim.Region.ScriptEngine.Common.ScriptEngineBase } } + private ScriptEngine lastScriptEngine; // Keep track of what ScriptEngine instance we are at so we can give exception /// /// A thread should run in this loop and check all running scripts /// public void MaintenanceLoop() { - if (m_ScriptEngine.m_EventQueueManager.maxFunctionExecutionTimens < MaintenanceLoopms) - m_ScriptEngine.Log.Warn("[" + m_ScriptEngine.ScriptEngineName + "]: " + - "Configuration error: MaxEventExecutionTimeMs is less than MaintenanceLoopms.
