From f901a3820497e0d99accb6f5f60f6517e07c2c8f Mon Sep 17 00:00:00 2001 From: Oren Hurvitz Date: Thu, 28 Nov 2013 23:07:14 +0200 Subject: Improved logging of HTTP requests - MemoryBuffer isn't seekable, so we can't log it. Log the string instead. - Handle compressed streams - Don't attempt to dump binary data. Either don't log it at all (if we know it's binary), or at least convert non-ASCII characters to ASCII. - Log responses to HTTP requests - Use the same log prefix for all of these log messages ("[LOGHTTP]"), to make them easy to see at a glance - Increased the snippet length to 200 (80 doesn't show enough), and add "..." only if the message was actually truncated Resolves http://opensimulator.org/mantis/view.php?id=6949 --- .../Framework/Servers/HttpServer/BaseHttpServer.cs | 52 ++++++--- OpenSim/Framework/Util.cs | 40 +++++++ OpenSim/Framework/WebUtil.cs | 122 +++++++++++++++------ 3 files changed, 165 insertions(+), 49 deletions(-) (limited to 'OpenSim/Framework') diff --git a/OpenSim/Framework/Servers/HttpServer/BaseHttpServer.cs b/OpenSim/Framework/Servers/HttpServer/BaseHttpServer.cs index e243002..19231e1 100644 --- a/OpenSim/Framework/Servers/HttpServer/BaseHttpServer.cs +++ b/OpenSim/Framework/Servers/HttpServer/BaseHttpServer.cs @@ -46,6 +46,7 @@ using CoolHTTPListener = HttpServer.HttpListener; using HttpListener=System.Net.HttpListener; using LogPrio=HttpServer.LogPrio; using OpenSim.Framework.Monitoring; +using System.IO.Compression; namespace OpenSim.Framework.Servers.HttpServer { @@ -690,6 +691,23 @@ namespace OpenSim.Framework.Servers.HttpServer if (buffer != null) { + if (WebUtil.DebugLevel >= 5) + { + string output = System.Text.Encoding.UTF8.GetString(buffer); + + if (WebUtil.DebugLevel >= 6) + { + // Always truncate binary blobs.
