From 03993d0b14599358ac30a001cebd5b2145881c65 Mon Sep 17 00:00:00 2001 From: Justin Clark-Casey (justincc) Date: Wed, 2 Nov 2011 18:12:12 +0000 Subject: Fix race condition that would sometimes send or save appearance for the wrong avatar. In AvatarFactoryModule.HandleAppearanceUpdateTimer(), we loop through appearance save and send requests and dispatch via a FireAndForget thread. If there was more than one request in the save or send queue, then this led to a subtle race condition where the foreach loop would load in the next KeyValuePair before the thread was dispatched. This gave the thread the wrong avatar ID, leaving some avatar appearance cloudy since appearance data was never sent. This change loads the fields into local references so that this doesn't happen. --- OpenSim/Region/Framework/Scenes/ScenePresence.cs | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'OpenSim/Region/Framework/Scenes') diff --git a/OpenSim/Region/Framework/Scenes/ScenePresence.cs b/OpenSim/Region/Framework/Scenes/ScenePresence.cs index 29966f9..3e3fb0f 100644 --- a/OpenSim/Region/Framework/Scenes/ScenePresence.cs +++ b/OpenSim/Region/Framework/Scenes/ScenePresence.cs @@ -2628,7 +2628,8 @@ namespace OpenSim.Region.Framework.Scenes /// public void SendAppearanceToAllOtherAgents() { - //m_log.DebugFormat("[SCENE PRESENCE] SendAppearanceToAllOtherAgents: {0} ({1})", Name, UUID); +// m_log.DebugFormat("[SCENE PRESENCE] SendAppearanceToAllOtherAgents: {0} {1}", Name, UUID); + // only send update from root agents to other clients; children are only "listening posts" if (IsChildAgent) { @@ -2656,7 +2657,7 @@ namespace OpenSim.Region.Framework.Scenes /// public void SendOtherAgentsAppearanceToMe() { - //m_log.DebugFormat("[SCENE PRESENCE] SendOtherAgentsAppearanceToMe: {0} ({1})", Name, UUID); +// m_log.DebugFormat("[SCENE PRESENCE] SendOtherAgentsAppearanceToMe: {0} {1}", Name, UUID); int count = 0; m_scene.ForEachRootScenePresence(delegate(ScenePresence scenePresence) -- cgit v1.1 From e2c51a977d42822fe78ae0744117afb7bf509d35 Mon Sep 17 00:00:00 2001 From: Dan Lake Date: Wed, 2 Nov 2011 14:59:00 -0700 Subject: Changes UpdateFlag in SOP to an enumeration of NONE, TERSE and FULL. UpdateFlag is now referenced/used only within SOP and SOG. Outsiders are using ScheduleFullUpdate, ScheduleTerseUpdate or ClearUpdateSchedule on SOP consistently now. Also started working toward eliminating those calls to ScheduleFullUpdate, ScheduleTerseUpdate or ClearUpdateSchedule from outside SOP in favor of just setting properties on SOP and let SOP decide if an update should be scheduled. This consolidates the update policy within SOP and the client rather than everywhere that makes changes to SOP. Some places forget to call update while others call it multiple times, "just to be sure". UpdateFlag and Schedule*Update will both be made private shortly. UpdateFlag is intended to be transient and internal to SOP so it has been removed from XML serializer for SOPs. --- OpenSim/Region/Framework/Scenes/SceneGraph.cs | 2 +- .../Region/Framework/Scenes/SceneObjectGroup.cs | 6 +- OpenSim/Region/Framework/Scenes/SceneObjectPart.cs | 101 +++++++++++---------- OpenSim/Region/Framework/Scenes/ScenePresence.cs | 2 +- .../Scenes/Serialization/SceneObjectSerializer.cs | 7 -- .../Scenes/Tests/SceneObjectLinkingTests.cs | 16 ++-- OpenSim/Region/Framework/Scenes/UndoState.cs | 6 +- 7 files changed, 66 insertions(+), 74 deletions(-) (limited to 'OpenSim/Region/Framework/Scenes') diff --git a/OpenSim/Region/Framework/Scenes/SceneGraph.cs b/OpenSim/Region/Framework/Scenes/SceneGraph.cs index 1af18e7..82ded28 100644 --- a/OpenSim/Region/Framework/Scenes/SceneGraph.cs +++ b/OpenSim/Region/Framework/Scenes/SceneGraph.cs @@ -1799,7 +1799,7 @@ namespace OpenSim.Region.Framework.Scenes newSet.RemoveAt(0); foreach (SceneObjectPart newChild in newSet) - newChild.UpdateFlag = 0; + newChild.ClearUpdateSchedule(); LinkObjects(newRoot, newSet); if (!affectedGroups.Contains(newRoot.ParentGroup)) diff --git a/OpenSim/Region/Framework/Scenes/SceneObjectGroup.cs b/OpenSim/Region/Framework/Scenes/SceneObjectGroup.cs index 2ea9854..a0a7344 100644 --- a/OpenSim/Region/Framework/Scenes/SceneObjectGroup.cs +++ b/OpenSim/Region/Framework/Scenes/SceneObjectGroup.cs @@ -1157,7 +1157,7 @@ namespace OpenSim.Region.Framework.Scenes if (!silent) { - part.UpdateFlag = 0; + part.ClearUpdateSchedule(); if (part == m_rootPart) { if (!IsAttachment || (AttachedAvatar == avatar.ControllingClient.AgentId) || @@ -1735,13 +1735,13 @@ namespace OpenSim.Region.Framework.Scenes if (UsePhysics && !AbsolutePosition.ApproxEquals(lastPhysGroupPos, 0.02f)) { - m_rootPart.UpdateFlag = 1; + m_rootPart.UpdateFlag = UpdateRequired.TERSE; lastPhysGroupPos = AbsolutePosition; } if (UsePhysics && !GroupRotation.ApproxEquals(lastPhysGroupRot, 0.1f)) { - m_rootPart.UpdateFlag = 1; + m_rootPart.UpdateFlag = UpdateRequired.TERSE; lastPhysGroupRot = GroupRotation; } diff --git a/OpenSim/Region/Framework/Scenes/SceneObjectPart.cs b/OpenSim/Region/Framework/Scenes/SceneObjectPart.cs index b68cc9f..44f822c 100644 --- a/OpenSim/Region/Framework/Scenes/SceneObjectPart.cs +++ b/OpenSim/Region/Framework/Scenes/SceneObjectPart.cs @@ -106,6 +106,13 @@ namespace OpenSim.Region.Framework.Scenes SCULPT = 7 } + public enum UpdateRequired : byte + { + NONE = 0, + TERSE = 1, + FULL = 2 + } + #endregion Enumerations public class SceneObjectPart : IScriptHost, ISceneEntity @@ -254,15 +261,7 @@ namespace OpenSim.Region.Framework.Scenes private bool m_passTouches; - /// - /// Only used internally to schedule client updates. - /// 0 - no update is scheduled - /// 1 - terse update scheduled - /// 2 - full update scheduled - /// - /// TODO - This should be an enumeration - /// - private byte m_updateFlag; + private UpdateRequired m_updateFlag; private PhysicsActor m_physActor; protected Vector3 m_acceleration; @@ -884,7 +883,15 @@ namespace OpenSim.Region.Framework.Scenes } } - /// + /// Update angular velocity and schedule terse update. + public void UpdateAngularVelocity(Vector3 avel) + { + AngularVelocity = avel; + ScheduleTerseUpdate(); + ParentGroup.HasGroupChanged = true; + } + + /// Get or set angular velocity.
