From e9cef70f892bfbf4aad0e4471a958367766d849a Mon Sep 17 00:00:00 2001 From: Teravus Ovares Date: Sat, 3 Jan 2009 03:30:03 +0000 Subject: * Updates the sim stats module. Cleans out some of the rot. * Adds a prototype web stats module which is disabled by default. It's functional with one report right now, however, the database structure may change, so I don't recommend enabling this to keep actual stats right now. I'll let you know when it's safe. * Adds Prototype for ajaxy web content * removed a warning or two. --- CONTRIBUTORS.txt | 1 + OpenSim/Framework/Servers/BaseHttpServer.cs | 3 +- OpenSim/Framework/SimStats.cs | 9 +- .../Framework/Statistics/SimExtraStatsCollector.cs | 65 +- .../ClientStack/LindenUDP/LLPacketHandler.cs | 4 + OpenSim/Region/Environment/Scenes/Scene.cs | 78 +- OpenSim/Region/Environment/Scenes/SceneGraph.cs | 11 + .../Region/Environment/Scenes/SimStatsReporter.cs | 13 +- .../Region/UserStatistics/ActiveConnectionsAJAX.cs | 185 + OpenSim/Region/UserStatistics/Default_Report.cs | 215 + OpenSim/Region/UserStatistics/HTMLUtil.cs | 185 + OpenSim/Region/UserStatistics/IStatsReport.cs | 10 + .../Region/UserStatistics/Prototype_distributor.cs | 33 + OpenSim/Region/UserStatistics/SimStatsAJAX.cs | 190 + .../Region/UserStatistics/Updater_distributor.cs | 35 + OpenSim/Region/UserStatistics/WebStatsModule.cs | 1083 +++++ ThirdPartyLicenses/Prototype.txt | 16 + bin/data/prototype.js | 4222 ++++++++++++++++++++ bin/data/updater.js | 20 + prebuild.xml | 48 + 20 files changed, 6360 insertions(+), 66 deletions(-) create mode 100644 OpenSim/Region/UserStatistics/ActiveConnectionsAJAX.cs create mode 100644 OpenSim/Region/UserStatistics/Default_Report.cs create mode 100644 OpenSim/Region/UserStatistics/HTMLUtil.cs create mode 100644 OpenSim/Region/UserStatistics/IStatsReport.cs create mode 100644 OpenSim/Region/UserStatistics/Prototype_distributor.cs create mode 100644 OpenSim/Region/UserStatistics/SimStatsAJAX.cs create mode 100644 OpenSim/Region/UserStatistics/Updater_distributor.cs create mode 100644 OpenSim/Region/UserStatistics/WebStatsModule.cs create mode 100644 ThirdPartyLicenses/Prototype.txt create mode 100644 bin/data/prototype.js create mode 100644 bin/data/updater.js diff --git a/CONTRIBUTORS.txt b/CONTRIBUTORS.txt index b4fff79..bb6503e 100644 --- a/CONTRIBUTORS.txt +++ b/CONTRIBUTORS.txt @@ -113,6 +113,7 @@ This software uses components from the following developers: * Prebuild (http://sourceforge.net/projects/dnpb/) * LibSecondLife (http://www.libsecondlife.org/wiki/Main_Page) * DotNetOpenMail v0.5.8b (http://dotnetopenmail.sourceforge.net) +* Prototype JavaScript Framework ajax (http://www.prototypejs.org/) In addition, we would like to thank: diff --git a/OpenSim/Framework/Servers/BaseHttpServer.cs b/OpenSim/Framework/Servers/BaseHttpServer.cs index 51658f3..ea356ac 100644 --- a/OpenSim/Framework/Servers/BaseHttpServer.cs +++ b/OpenSim/Framework/Servers/BaseHttpServer.cs @@ -1091,6 +1091,7 @@ namespace OpenSim.Framework.Servers { host = (string)headervals["Host"];
