From 8fc350125c671baeae6b7f8b1814251009f4f50a Mon Sep 17 00:00:00 2001 From: Monty Brandenberg Date: Wed, 23 May 2012 19:12:09 -0400 Subject: Integrate llcorehttp library into lltexturefetch design. This is the first functional viewer pass with the HTTP work of the texture fetch code performed by the llcorehttp library. Not exactly a 'drop-in' replacement but a work-alike with some changes (e.g. handler notification in consumer thread versus responder notification in worker thread). This also includes some temporary changes in the priority scheme to prevent the kind of priority inversion found in VWR-28996. Scheme used here does provide liveness if not optimal responsiveness or order-of-operation. The llcorehttp library at this point is far from optimally performing. Its worker thread is making relatively poor use of cycles it gets and it doesn't idle or sleep intelligently yet. This early integration step helps shake out the interfaces, implementation niceties will be covered soon. --- indra/llcorehttp/_httpopcancel.cpp | 82 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 82 insertions(+) create mode 100644 indra/llcorehttp/_httpopcancel.cpp (limited to 'indra/llcorehttp/_httpopcancel.cpp') diff --git a/indra/llcorehttp/_httpopcancel.cpp b/indra/llcorehttp/_httpopcancel.cpp new file mode 100644 index 0000000000..69dbff4bb4 --- /dev/null +++ b/indra/llcorehttp/_httpopcancel.cpp @@ -0,0 +1,82 @@ +/** + * @file _httpopcancel.cpp + * @brief Definitions for internal class HttpOpCancel + * + * $LicenseInfo:firstyear=2012&license=viewerlgpl$ + * Second Life Viewer Source Code + * Copyright (C) 2012, 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 + * License as published by the Free Software Foundation; + * version 2.1 of the License only. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Implemented/modified PUT & POST to not used chunked encoding for the request. Made the unit test much happier and probably a better thing for the pipeline. Have a cheesy static & dynamic proxy capability using both local options and a way to wire into LLProxy in llmessages. Not a clean thing but it will get the proxy path working with both socks5 & http proxies. Refactoring to get rid of unneeded library handler and unified an HttpStatus return for all requests. Big batch of code removed as a result of that and more is possible as well as some syscall avoidance with a bit more work. Boosted the unit tests for simple PUT & POST test which revealed the test harness does *not* like chunked encoding so we'll avoid it for now (and don't really need it in any of our schemes). --- indra/llcorehttp/_httpopcancel.cpp | 11 ----------- 1 file changed, 11 deletions(-) (limited to 'indra/llcorehttp/_httpopcancel.cpp') diff --git a/indra/llcorehttp/_httpopcancel.cpp b/indra/llcorehttp/_httpopcancel.cpp index 69dbff4bb4..ad624d2e57 100644 --- a/indra/llcorehttp/_httpopcancel.cpp +++ b/indra/llcorehttp/_httpopcancel.cpp @@ -66,17 +66,6 @@ void HttpOpCancel::stageFromRequest(HttpService * service) } -void HttpOpCancel::visitNotifier(HttpRequest * request) -{ - if (mLibraryHandler) - { - HttpResponse * response = new HttpResponse(); - mLibraryHandler->onCompleted(static_cast(this), response); - response->release(); - } -} - - } // end namespace LLCore -- cgit v1.2.3 From 2d7b7de20327a40be12a620debaae9917af16cd6 Mon Sep 17 00:00:00 2001 From: Monty Brandenberg Date: Tue, 3 Jul 2012 13:06:46 -0400 Subject: More integration work for texture fetch timeouts. The fetch state machine received a new timeout during the WAIT_HTTP_REQ state. For the integration, rather than jump the state to done, we issue a request cancel and let the notification plumbing do the rest without any race conditions or special-case logic. --- indra/llcorehttp/_httpopcancel.cpp | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'indra/llcorehttp/_httpopcancel.cpp') diff --git a/indra/llcorehttp/_httpopcancel.cpp b/indra/llcorehttp/_httpopcancel.cpp index ad624d2e57..5c1f484109 100644 --- a/indra/llcorehttp/_httpopcancel.cpp +++ b/indra/llcorehttp/_httpopcancel.cpp @@ -61,7 +61,11 @@ HttpOpCancel::~HttpOpCancel() void HttpOpCancel::stageFromRequest(HttpService * service) { - // *FIXME: Need cancel functionality into services + if (! service->cancel(mHandle)) + { + mStatus = HttpStatus(HttpStatus::LLCORE, HE_HANDLE_NOT_FOUND); + } + addAsReply(); } -- cgit v1.2.3 From f5f51d3cda8861b3b3a380cc96aaca98e572c377 Mon Sep 17 00:00:00 2001 From: Monty Brandenberg Date: Sat, 7 Jul 2012 19:35:32 -0400 Subject: SH-3185 Fill in some FIXME/TODO cases Also added some comments and changed the callback userdata argument to be an HttpOpRequest rather than a libcurl handle.
