From 746829967315cc82560a855a4772e45888bf8fbe Mon Sep 17 00:00:00 2001 From: Justin Clark-Casey (justincc) Date: Tue, 3 Apr 2012 05:50:13 +0100 Subject: Eliminate race condition where many callers would check SOP.PhysicsActor != null then assume it was still not null in later code. Another thread could come and turn off physics for a part (null PhysicsActor) at any point. Had to turn off localCopy on warp3D CoreModules section in prebuild.xml since on current nant this copies all DLLs in bin/ which can be a very large number with compiled DLLs No obvious reason for doing that copy - nothing else does it. --- .../EntityTransfer/EntityTransferModule.cs | 8 +- OpenSim/Region/Framework/Scenes/Scene.cs | 4 - OpenSim/Region/Framework/Scenes/SceneGraph.cs | 3 +- .../Region/Framework/Scenes/SceneObjectGroup.cs | 140 ++++++++------ OpenSim/Region/Framework/Scenes/SceneObjectPart.cs | 207 ++++++++++++--------- 5 files changed, 208 insertions(+), 154 deletions(-) (limited to 'OpenSim') diff --git a/OpenSim/Region/CoreModules/Framework/EntityTransfer/EntityTransferModule.cs b/OpenSim/Region/CoreModules/Framework/EntityTransfer/EntityTransferModule.cs index 427a49d..86e10d4 100644 --- a/OpenSim/Region/CoreModules/Framework/EntityTransfer/EntityTransferModule.cs +++ b/OpenSim/Region/CoreModules/Framework/EntityTransfer/EntityTransferModule.cs @@ -36,6 +36,7 @@ using OpenSim.Framework.Capabilities; using OpenSim.Framework.Client; using OpenSim.Region.Framework.Interfaces; using OpenSim.Region.Framework.Scenes; +using OpenSim.Region.Physics.Manager; using OpenSim.Services.Interfaces; using GridRegion = OpenSim.Services.Interfaces.GridRegion; @@ -1803,10 +1804,9 @@ namespace OpenSim.Region.CoreModules.Framework.EntityTransfer { if (!grp.IsDeleted) { - if (grp.RootPart.PhysActor != null) - { - grp.RootPart.PhysActor.CrossingFailure(); - } + PhysicsActor pa = grp.RootPart.PhysActor; + if (pa != null) + pa.CrossingFailure(); } m_log.ErrorFormat("[ENTITY TRANSFER MODULE]: Prim crossing failed for {0}", grp); diff --git a/OpenSim/Region/Framework/Scenes/Scene.cs b/OpenSim/Region/Framework/Scenes/Scene.cs index 06f7c0f..29825a2 100644 --- a/OpenSim/Region/Framework/Scenes/Scene.cs +++ b/OpenSim/Region/Framework/Scenes/Scene.cs @@ -642,10 +642,6 @@ namespace OpenSim.Region.Framework.Scenes #endregion Region Settings - MainConsole.Instance.Commands.AddCommand("Estates", false, "reload estate", - "reload estate", - "Reload the estate data", HandleReloadEstate); - //Bind Storage Manager functions to some land manager functions for this scene EventManager.OnLandObjectAdded += new EventManager.LandObjectAdded(simDataService.StoreLandObject); diff --git a/OpenSim/Region/Framework/Scenes/SceneGraph.cs b/OpenSim/Region/Framework/Scenes/SceneGraph.cs index 8a05772..0098add 100644 --- a/OpenSim/Region/Framework/Scenes/SceneGraph.cs +++ b/OpenSim/Region/Framework/Scenes/SceneGraph.cs @@ -306,7 +306,8 @@ namespace OpenSim.Region.Framework.Scenes if (rot != null) sceneObject.UpdateGroupRotationR((Quaternion)rot); - if (sceneObject.RootPart.PhysActor != null && sceneObject.RootPart.PhysActor.IsPhysical && vel != Vector3.Zero) + PhysicsActor pa = sceneObject.RootPart.PhysActor; + if (pa != null && pa.IsPhysical && vel != Vector3.Zero) { sceneObject.RootPart.ApplyImpulse((vel * sceneObject.GetMass()), false); sceneObject.Velocity = vel; diff --git a/OpenSim/Region/Framework/Scenes/SceneObjectGroup.cs b/OpenSim/Region/Framework/Scenes/SceneObjectGroup.cs index 04b3766..87fdc41 100644 --- a/OpenSim/Region/Framework/Scenes/SceneObjectGroup.cs +++ b/OpenSim/Region/Framework/Scenes/SceneObjectGroup.cs @@ -523,16 +523,21 @@ namespace OpenSim.Region.Framework.Scenes { m_isSelected = value; // Tell physics engine that group is selected - if (m_rootPart.PhysActor != null) + + PhysicsActor pa = m_rootPart.PhysActor; + if (pa != null) { - m_rootPart.PhysActor.Selected = value; + pa.Selected = value; + // Pass it on to the children.
