From e79a88c8ccfadcd260892000d4dec2ae921b26de Mon Sep 17 00:00:00 2001 From: Monty Brandenberg Date: Tue, 12 Aug 2014 18:21:26 -0400 Subject: Better support for dynamic option changes in llcorehttp. Libcurl has some problems disabling pipelining on a multi handle with outstanding requests so build a more conservative system that allows requests to drain before setting curl multi options. Would rather not have this but it is significantly safer. "HttpPipelining" debug setting is now fully dynamic. Connection limits can also be made dynamic in the near future. Upped the default connection count back to 8 for now but will revisit this in the tuning phase. It might be time to combine mesh and textures into a single asset class. For normal server operations that would be a clear path, but for server under load, the current scheme may be better. Minor cleanup in logging to elminate some redundant strings. Might add some more tracing to the stall logic 'just in case'. --- indra/llcorehttp/_httplibcurl.h | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) (limited to 'indra/llcorehttp/_httplibcurl.h') diff --git a/indra/llcorehttp/_httplibcurl.h b/indra/llcorehttp/_httplibcurl.h index 67f98dd4f0..2c7ad1fa8e 100755 --- a/indra/llcorehttp/_httplibcurl.h +++ b/indra/llcorehttp/_httplibcurl.h @@ -4,7 +4,7 @@ * * $LicenseInfo:firstyear=2012&license=viewerlgpl$ * Second Life Viewer Source Code - * Copyright (C) 2012-2013, Linden Research, Inc. + * Copyright (C) 2012-2014, Linden Research, Inc. * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public @@ -116,6 +116,14 @@ public: /// Threading: called by worker thread. bool cancel(HttpHandle handle); + /// Informs transport that a particular policy class has had + /// options changed and so should effect any transport state + /// change necessary to effect those changes.
