From 4b71b88114c6ac149571512c57ea005d85147f54 Mon Sep 17 00:00:00 2001 From: diva Date: Mon, 15 Dec 2008 16:23:34 +0000 Subject: Bug fix in new child agents management. Thanks DigiDaz for helping identify this issue. We need to update all child agents whenever the root agent crosses regions. The update now includes child agents in common neighbours. This is so that those get updated with the seeds of the new child agents that are spawned from the receiving region. This also fixes some timing issues. We need to close child agents from the originating region before we update child agents in the receiving region. --- .../Hypergrid/HGSceneCommunicationService.cs | 82 +++++++------ OpenSim/Region/Environment/Scenes/Scene.cs | 17 ++- .../Scenes/SceneCommunicationService.cs | 131 ++++++++++++--------- OpenSim/Region/Environment/Scenes/ScenePresence.cs | 60 +++++++--- 4 files changed, 174 insertions(+), 116 deletions(-) diff --git a/OpenSim/Region/Environment/Scenes/Hypergrid/HGSceneCommunicationService.cs b/OpenSim/Region/Environment/Scenes/Hypergrid/HGSceneCommunicationService.cs index 9e23831..595ac09 100644 --- a/OpenSim/Region/Environment/Scenes/Hypergrid/HGSceneCommunicationService.cs +++ b/OpenSim/Region/Environment/Scenes/Hypergrid/HGSceneCommunicationService.cs @@ -169,6 +169,17 @@ namespace OpenSim.Region.Environment.Scenes.Hypergrid // once we reach here... //avatar.Scene.RemoveCapsHandler(avatar.UUID); + // Let's close some agents + if (isHyperLink) // close them all except this one + { + List regions = new List(avatar.KnownChildRegionHandles); + regions.Remove(avatar.Scene.RegionInfo.RegionHandle); + SendCloseChildAgentConnections(avatar.UUID, regions); + } + else // close just a few + avatar.CloseChildAgents(newRegionX, newRegionY); + + string capsPath = String.Empty; AgentCircuitData agent = avatar.ControllingClient.RequestClientInfo(); agent.BaseFolder = UUID.Zero; agent.InventoryFolder = UUID.Zero; @@ -178,38 +189,39 @@ namespace OpenSim.Region.Environment.Scenes.Hypergrid { // brand new agent agent.CapsPath = Util.GetRandomCapsPath(); + if (!m_commsProvider.InterRegion.InformRegionOfChildAgent(reg.RegionHandle, agent)) + { + avatar.ControllingClient.SendTeleportFailed("Destination is not accepting teleports."); + return; + } + + // TODO Should construct this behind a method + capsPath = + "http://" + reg.ExternalHostName + ":" + reg.HttpPort + + "/CAPS/" + agent.CapsPath + "0000/"; + + if (eq != null) + { + OSD Item = EventQueueHelper.EnableSimulator(realHandle, reg.ExternalEndPoint); + eq.Enqueue(Item, avatar.UUID); + + Item = EventQueueHelper.EstablishAgentCommunication(avatar.UUID, reg.ExternalEndPoint.ToString(), capsPath); + eq.Enqueue(Item, avatar.UUID); + } + else + { + avatar.ControllingClient.InformClientOfNeighbour(realHandle, reg.ExternalEndPoint); + // TODO: make Event Queue disablable!
