From af22b7cb1af041ab685128f507265d9c7e7fac9c Mon Sep 17 00:00:00 2001 From: Marck Date: Tue, 22 Feb 2011 13:00:45 +0100 Subject: [PATCH 1/4] GetRegion(s)ByName with SQLite behaves like it does with other databases. The in-memory storage of region data that is used by default with SQLite now handles wildcards in region names in the same way as SQL queries do with other databases. --- OpenSim/Data/Null/NullRegionData.cs | 50 ++++++++++++++++++++++------- 1 file changed, 39 insertions(+), 11 deletions(-) diff --git a/OpenSim/Data/Null/NullRegionData.cs b/OpenSim/Data/Null/NullRegionData.cs index 2065355890..53e5207a6e 100644 --- a/OpenSim/Data/Null/NullRegionData.cs +++ b/OpenSim/Data/Null/NullRegionData.cs @@ -51,27 +51,55 @@ namespace OpenSim.Data.Null //Console.WriteLine("[XXX] NullRegionData constructor"); } + private delegate bool Matcher(string value); + public List Get(string regionName, UUID scopeID) { if (Instance != this) return Instance.Get(regionName, scopeID); + string cleanName = regionName.ToLower(); + + // Handle SQL wildcards + const string wildcard = "%"; + bool wildcardPrefix = false; + bool wildcardSuffix = false; + if (cleanName.Equals(wildcard)) + { + wildcardPrefix = wildcardSuffix = true; + cleanName = string.Empty; + } + else + { + if (cleanName.StartsWith(wildcard)) + { + wildcardPrefix = true; + cleanName = cleanName.Substring(1); + } + if (regionName.EndsWith(wildcard)) + { + wildcardSuffix = true; + cleanName = cleanName.Remove(cleanName.Length - 1); + } + } + Matcher queryMatch; + if (wildcardPrefix && wildcardSuffix) + queryMatch = delegate(string s) { return s.Contains(cleanName); }; + else if (wildcardSuffix) + queryMatch = delegate(string s) { return s.StartsWith(cleanName); }; + else if (wildcardPrefix) + queryMatch = delegate(string s) { return s.EndsWith(cleanName); }; + else + queryMatch = delegate(string s) { return s.Equals(cleanName); }; + + // Find region data List ret = new List(); foreach (RegionData r in m_regionData.Values) { - if (regionName.Contains("%")) - { - string cleanname = regionName.Replace("%", ""); - m_log.DebugFormat("[NULL REGION DATA]: comparing {0} to {1}", cleanname.ToLower(), r.RegionName.ToLower()); - if (r.RegionName.ToLower().Contains(cleanname.ToLower())) + m_log.DebugFormat("[NULL REGION DATA]: comparing {0} to {1}", cleanName, r.RegionName.ToLower()); + if (queryMatch(r.RegionName.ToLower())) ret.Add(r); - } - else - { - if (r.RegionName.ToLower() == regionName.ToLower()) - ret.Add(r); - } } if (ret.Count > 0) From 5a16fa882c0f1a6200bc3fdb63b0f4564acf0e6d Mon Sep 17 00:00:00 2001 From: Mic Bowman Date: Tue, 22 Feb 2011 13:23:54 -0800 Subject: [PATCH 2/4] Parameterizes the view distance used to compute and manage child agents in neighbor regions. This means you can extend the view on a simulator beyond the default 3x3 regions. This uses a region default draw distance and should be replaced at some point by the avatar specified draw distance. That will require more careful, dynamic recomputation of child agents every time the draw distance changes. WARNING: this is experimental and has known instabilities. specifically all regions "within site" should be running the same default draw distance or agents will not be closed correctly. --- OpenSim/Framework/Util.cs | 13 +++++-- .../EntityTransfer/EntityTransferModule.cs | 37 +++++++++++++------ .../EntityTransfer/HGEntityTransferModule.cs | 4 +- OpenSim/Region/Framework/Scenes/Scene.cs | 9 +++++ .../Region/Framework/Scenes/ScenePresence.cs | 24 +++++++++--- bin/OpenSimDefaults.ini | 7 ++++ 6 files changed, 73 insertions(+), 21 deletions(-) diff --git a/OpenSim/Framework/Util.cs b/OpenSim/Framework/Util.cs index 533e53abd5..5a5046e547 100644 --- a/OpenSim/Framework/Util.cs +++ b/OpenSim/Framework/Util.cs @@ -459,10 +459,17 @@ namespace OpenSim.Framework /// Old region y-coord /// New region y-coord /// - public static bool IsOutsideView(uint oldx, uint newx, uint oldy, uint newy) + public static bool IsOutsideView(float drawdist, uint oldx, uint newx, uint oldy, uint newy) { - // Eventually this will be a function of the draw distance / camera position too. - return (((int)Math.Abs((int)(oldx - newx)) > 1) || ((int)Math.Abs((int)(oldy - newy)) > 1)); + int dd = (int)((drawdist + Constants.RegionSize - 1) / Constants.RegionSize); + + int startX = (int)oldx - dd; + int startY = (int)oldy - dd; + + int endX = (int)oldx + dd; + int endY = (int)oldy + dd; + + return (newx < startX || endX < newx || newy < startY || endY < newy); } public static string FieldToString(byte[] bytes) diff --git a/OpenSim/Region/CoreModules/Framework/EntityTransfer/EntityTransferModule.cs b/OpenSim/Region/CoreModules/Framework/EntityTransfer/EntityTransferModule.cs index 98aa563a4f..95c771e60f 100644 --- a/OpenSim/Region/CoreModules/Framework/EntityTransfer/EntityTransferModule.cs +++ b/OpenSim/Region/CoreModules/Framework/EntityTransfer/EntityTransferModule.cs @@ -318,7 +318,7 @@ namespace OpenSim.Region.CoreModules.Framework.EntityTransfer agentCircuit.Id0 = currentAgentCircuit.Id0; } - if (NeedsNewAgent(oldRegionX, newRegionX, oldRegionY, newRegionY)) + if (NeedsNewAgent(sp.DrawDistance, oldRegionX, newRegionX, oldRegionY, newRegionY)) { // brand new agent, let's create a new caps seed agentCircuit.CapsPath = CapsUtil.GetRandomCapsObjectPath(); @@ -336,7 +336,7 @@ namespace OpenSim.Region.CoreModules.Framework.EntityTransfer // OK, it got this agent.
