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/CMakeLists.txt | 2 + indra/llcorehttp/_httplibcurl.cpp | 11 +- indra/llcorehttp/_httplibcurl.h | 3 +- indra/llcorehttp/_httpopcancel.cpp | 82 ++++ indra/llcorehttp/_httpopcancel.h | 75 ++++ indra/llcorehttp/_httpoperation.h | 25 -- indra/llcorehttp/_httpoprequest.cpp | 105 +++-- indra/llcorehttp/_httpoprequest.h | 9 +- indra/llcorehttp/_httppolicy.h | 3 +- indra/llcorehttp/_httpreplyqueue.h | 2 +- indra/llcorehttp/_httprequestqueue.h | 2 +- indra/llcorehttp/_httpservice.h | 4 +- indra/llcorehttp/httpcommon.cpp | 90 ++++- indra/llcorehttp/httpcommon.h | 59 ++- indra/llcorehttp/httprequest.cpp | 17 + indra/llcorehttp/httpresponse.cpp | 3 +- indra/llcorehttp/httpresponse.h | 32 +- indra/llcorehttp/tests/test_httpstatus.hpp | 102 +++++ indra/newview/llappviewer.cpp | 159 ++++++++ indra/newview/lltexturefetch.cpp | 610 +++++++++++++++++------------ indra/newview/lltexturefetch.h | 19 +- 21 files changed, 1057 insertions(+), 357 deletions(-) create mode 100644 indra/llcorehttp/_httpopcancel.cpp create mode 100644 indra/llcorehttp/_httpopcancel.h (limited to 'indra') diff --git a/indra/llcorehttp/CMakeLists.txt b/indra/llcorehttp/CMakeLists.txt index 81c502b642..ae92fb96fd 100644 --- a/indra/llcorehttp/CMakeLists.txt +++ b/indra/llcorehttp/CMakeLists.txt @@ -30,6 +30,7 @@ set(llcorehttp_SOURCE_FILES _httprequestqueue.cpp _httpoperation.cpp _httpoprequest.cpp + _httpopcancel.cpp _httpreplyqueue.cpp _httppolicy.cpp _httplibcurl.cpp @@ -49,6 +50,7 @@ set(llcorehttp_HEADER_FILES httpresponse.h _httpoperation.h _httpoprequest.h + _httpopcancel.h _httprequestqueue.h _httpreplyqueue.h _httpservice.h diff --git a/indra/llcorehttp/_httplibcurl.cpp b/indra/llcorehttp/_httplibcurl.cpp index 15be977adf..1b951818e4 100644 --- a/indra/llcorehttp/_httplibcurl.cpp +++ b/indra/llcorehttp/_httplibcurl.cpp @@ -27,7 +27,6 @@ #include "_httplibcurl.h" #include "httpheaders.h" - #include "_httpoprequest.h" #include "_httpservice.h" @@ -173,8 +172,11 @@ void HttpLibcurl::completeRequest(CURLM * multi_handle, CURL * handle, CURLcode { int http_status(200); - curl_easy_getinfo(handle, CURLINFO_RESPONSE_CODE, &status); - op->mReplyStatus = http_status; + curl_easy_getinfo(handle, CURLINFO_RESPONSE_CODE, &http_status); + op->mStatus = LLCore::HttpStatus(http_status, + (http_status >= 200 && http_status <= 299 + ?

Identified and reacted to the priority inversion problem we have in texturefetch. Includes the introduction of a priority_queue for the requests that are ready. Start some parameterization in anticipation of having policy_class everywhere. Removed _assert.h which isn't really needed in indra codebase. Implemented async setPriority request (which I hope I can get rid of eventually along with all priorities in this library). Converted to using unsigned int for priority rather than float. Implemented POST and did groundwork for PUT. --- indra/llcorehttp/CMakeLists.txt | 27 ++-- indra/llcorehttp/_assert.h | 39 ----- indra/llcorehttp/_httplibcurl.cpp | 52 ++++-- indra/llcorehttp/_httplibcurl.h | 27 +++- indra/llcorehttp/_httpopcancel.h | 2 +- indra/llcorehttp/_httpoperation.cpp | 8 +- indra/llcorehttp/_httpoperation.h | 42 ++++- indra/llcorehttp/_httpoprequest.cpp | 113 ++++++++++++- indra/llcorehttp/_httpoprequest.h | 11 +- indra/llcorehttp/_httpopsetpriority.cpp | 77 +++++++++ indra/llcorehttp/_httpopsetpriority.h | 70 +++++++++ indra/llcorehttp/_httppolicy.cpp | 97 ++++++++++-- indra/llcorehttp/_httppolicy.h | 28 +++- indra/llcorehttp/_httpreadyqueue.h | 85 ++++++++++ indra/llcorehttp/_httprequestqueue.cpp | 2 +- indra/llcorehttp/_httpservice.cpp | 63 +++++--- indra/llcorehttp/_httpservice.h | 26 ++- indra/llcorehttp/_refcounted.h | 14 +- indra/llcorehttp/httpcommon.cpp | 15 +- indra/llcorehttp/httpcommon.h | 8 +- indra/llcorehttp/httprequest.cpp | 52 +++++- indra/llcorehttp/httprequest.h | 49 +++++- indra/llcorehttp/tests/test_httprequest.hpp | 2 +- indra/newview/lltexturefetch.cpp | 235 ++++++++++++---------------- indra/newview/lltexturefetch.h | 15 -- 25 files changed, 869 insertions(+), 290 deletions(-) delete mode 100644 indra/llcorehttp/_assert.h create mode 100644 indra/llcorehttp/_httpopsetpriority.cpp create mode 100644 indra/llcorehttp/_httpopsetpriority.h create mode 100644 indra/llcorehttp/_httpreadyqueue.h (limited to 'indra') diff --git a/indra/llcorehttp/CMakeLists.txt b/indra/llcorehttp/CMakeLists.txt index ae92fb96fd..85df5364db 100644 --- a/indra/llcorehttp/CMakeLists.txt +++ b/indra/llcorehttp/CMakeLists.txt @@ -23,17 +23,18 @@ include_directories( set(llcorehttp_SOURCE_FILES bufferarray.cpp httpcommon.cpp + httpheaders.cpp + httpoptions.cpp httprequest.cpp httpresponse.cpp - httpoptions.cpp - httpheaders.cpp - _httprequestqueue.cpp + _httplibcurl.cpp + _httpopcancel.cpp _httpoperation.cpp _httpoprequest.cpp - _httpopcancel.cpp - _httpreplyqueue.cpp + _httpopsetpriority.cpp _httppolicy.cpp - _httplibcurl.cpp + _httpreplyqueue.cpp + _httprequestqueue.cpp _httpservice.cpp _refcounted.cpp ) @@ -48,17 +49,19 @@ set(llcorehttp_HEADER_FILES httpoptions.h httprequest.h httpresponse.h + _assert.h + _httplibcurl.h + _httpopcancel.h _httpoperation.h _httpoprequest.h - _httpopcancel.h - _httprequestqueue.h + _httpopsetpriority.h + _httppolicy.h + _httpreadyqueue.h _httpreplyqueue.h + _httprequestqueue.h _httpservice.h - _httppolicy.h - _httplibcurl.h - _assert.h - _refcounted.h _mutex.h + _refcounted.h _thread.h ) diff --git a/indra/llcorehttp/_assert.h b/indra/llcorehttp/_assert.h deleted file mode 100644 index 054f23ef32..0000000000 --- a/indra/llcorehttp/_assert.h +++ /dev/null @@ -1,39 +0,0 @@ -/** - * @file _assert - * @brief assert abstraction - * - * $LicenseInfo:firstyear=2012&license=viewerlgpl$ - * 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.

This uses LLSD so that is also showing as compatible with the new library. --- indra/llcorehttp/CMakeLists.txt | 2 ++ indra/llcorehttp/_httplibcurl.cpp | 1 + indra/llcorehttp/_httpoprequest.cpp | 45 ++++++++++++++++++++++++++++++++----- indra/llcorehttp/_httppolicy.cpp | 4 ++-- indra/llcorehttp/_httppolicy.h | 10 +++++++++ indra/llcorehttp/_httpservice.h | 8 +++---- indra/llcorehttp/httpcommon.cpp | 5 ++++- indra/llcorehttp/httpcommon.h | 11 ++++++++- indra/llcorehttp/httprequest.cpp | 13 +++++++++-- indra/llcorehttp/httprequest.h | 16 +++++++------ indra/newview/llappviewer.cpp | 12 +++++++++- indra/newview/lltexturefetch.cpp | 37 +++++++++++++++++------------- 12 files changed, 126 insertions(+), 38 deletions(-) (limited to 'indra') diff --git a/indra/llcorehttp/CMakeLists.txt b/indra/llcorehttp/CMakeLists.txt index 9a073eb850..3fda524ddf 100644 --- a/indra/llcorehttp/CMakeLists.txt +++ b/indra/llcorehttp/CMakeLists.txt @@ -33,6 +33,7 @@ set(llcorehttp_SOURCE_FILES _httpoprequest.cpp _httpopsetpriority.cpp _httppolicy.cpp + _httppolicyglobal.cpp _httpreplyqueue.cpp _httprequestqueue.cpp _httpservice.cpp @@ -55,6 +56,7 @@ set(llcorehttp_HEADER_FILES _httpoprequest.h _httpopsetpriority.h _httppolicy.h + _httppolicyglobal.h _httpreadyqueue.h _httpreplyqueue.h _httprequestqueue.h diff --git a/indra/llcorehttp/_httplibcurl.cpp b/indra/llcorehttp/_httplibcurl.cpp index 704f9baac9..5272c391e8 100644 --- a/indra/llcorehttp/_httplibcurl.cpp +++ b/indra/llcorehttp/_httplibcurl.cpp @@ -27,6 +27,7 @@ #include "_httplibcurl.h" #include "httpheaders.h" +#include "bufferarray.h" #include "_httpoprequest.h" diff --git a/indra/llcorehttp/_httpoprequest.cpp b/indra/llcorehttp/_httpoprequest.cpp index f52ff5a44c..4bdc4a5257 100644 --- a/indra/llcorehttp/_httpoprequest.cpp +++ b/indra/llcorehttp/_httpoprequest.cpp @@ -40,8 +40,10 @@ #include "_httpreplyqueue.h" #include "_httpservice.h" #include "_httppolicy.h" +#include "_httppolicyglobal.h" #include "_httplibcurl.h" +#include "llhttpstatuscodes.h" namespace { @@ -153,14 +155,14 @@ HttpOpRequest::~HttpOpRequest() void HttpOpRequest::stageFromRequest(HttpService * service) { addRef(); - service->getPolicy()->addOp(this); // transfers refcount + service->getPolicy().addOp(this); // transfers refcount } void HttpOpRequest::stageFromReady(HttpService * service) { addRef(); - service->getTransport()->addOp(this); // transfers refcount + service->getTransport().addOp(this); // transfers refcount } @@ -195,6 +197,8 @@ void HttpOpRequest::stageFromActive(HttpService * service) void HttpOpRequest::visitNotifier(HttpRequest * request) { + static const HttpStatus partial_content(HTTP_PARTIAL_CONTENT, HE_SUCCESS); + if (mLibraryHandler) { HttpResponse * response = new HttpResponse(); @@ -208,9 +212,15 @@ void HttpOpRequest::visitNotifier(HttpRequest * request) offset = mReplyOffset; length = mReplyLength; } - else if (mReplyBody) + else if (mReplyBody && partial_content == mStatus) { - // Provide implicit offset/length from request/response + // Legacy grid services did not provide a 'Content-Range' + // header in responses to full- or partly-satisfyiable + // 'Range' requests.

There's a huge comment block introducing all of this at the beginning and I believe it's correct (though not quite complete). Keep it updated, people. Added a new state, WAIT_HTTP_RESOURCE, that's sort of a side-state of SEND_HTTP_REQ. If we hit a high-water mark for HTTP requests, the extra are shunted to the new state once. Once levels fall to a low-water mark, we run through a wait list of UUIDs, sort the valid ones by priority and release them for service. This keeps the HTTP layer busy while leaving the active queue shallow enough that requests can still be re-prioritzed cheaply. Priority model changed. The new state uses the PRIORITY_LOW mask, the old users of _LOW are now at PRIORITY_NORMAL and sleepers woken up after an external event are kicked off at PRIORITY_HIGH. This combination along with the new state should avoid priority inversion and keep things running without resorting to an infinite pipeline. New state displays as "HTW" with green text in the texture console. Request cancelation and worker run-down should now be more correct but this edge case may need more attention. --- indra/newview/lltexturefetch.cpp | 942 ++++++++++++++++++++++++++------------- indra/newview/lltexturefetch.h | 153 ++++++- indra/newview/lltextureview.cpp | 3 +- 3 files changed, 777 insertions(+), 321 deletions(-) (limited to 'indra') diff --git a/indra/newview/lltexturefetch.cpp b/indra/newview/lltexturefetch.cpp index f9294b4cd1..23232cb590 100644 --- a/indra/newview/lltexturefetch.cpp +++ b/indra/newview/lltexturefetch.cpp @@ -52,6 +52,7 @@ #include "llviewerassetstats.h" #include "llworld.h" #include "llsdserialize.h" +#include "llviewertexturelist.h" // debug #include "httprequest.h" #include "httphandler.h" @@ -60,6 +61,102 @@ ////////////////////////////////////////////////////////////////////////////// +// +// Introduction +// +// This is an attempt to document what's going on in here after-the-fact. +// It's a sincere attempt to be accurate but there will be mistakes. +// +// Purpose +// +// (What is this solving?) +// +// Threads +// +// Several threads are actively invoking code in this module.

Went in rather easily which surprised me. Added a retry queue similar to ready queue to the policy object which is sorted by retry time. Currently do five retries (after the initial try) delayed by .25, .5, 1, 2 and 5 seconds. Removed the retry logic from the lltexturefetch module. Upped the waiting time in the unit test for the retries.

We run a mocked HTTP service to handle requests and the integration tests run against it by picking up the LL_TEST_PORT environment variable when running. Add some checks and output to produce useful info when run in the wrong environment and when bad status is received.

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/CMakeLists.txt | 5 + indra/llcorehttp/_httpopcancel.cpp | 11 -- indra/llcorehttp/_httpopcancel.h | 3 - indra/llcorehttp/_httpoperation.cpp | 18 +- indra/llcorehttp/_httpoperation.h | 13 +- indra/llcorehttp/_httpoprequest.cpp | 63 +++++-- indra/llcorehttp/_httpoprequest.h | 7 + indra/llcorehttp/_httpopsetget.cpp | 105 +++++++++++ indra/llcorehttp/_httpopsetget.h | 78 ++++++++ indra/llcorehttp/_httpopsetpriority.cpp | 14 -- indra/llcorehttp/_httpopsetpriority.h | 4 +- indra/llcorehttp/_httppolicy.cpp | 6 + indra/llcorehttp/_httppolicy.h | 4 +- indra/llcorehttp/_httppolicyglobal.cpp | 38 ++-- indra/llcorehttp/_httppolicyglobal.h | 7 +- indra/llcorehttp/_httpservice.cpp | 11 +- indra/llcorehttp/_httpservice.h | 10 +- indra/llcorehttp/httprequest.cpp | 151 ++++++++-------- indra/llcorehttp/httprequest.h | 44 ++++- indra/llcorehttp/tests/llcorehttp_test.cpp | 6 + indra/llcorehttp/tests/test_httpoperation.hpp | 5 +- indra/llcorehttp/tests/test_httprequest.hpp | 239 +++++++++++++++++++++++++ indra/llcorehttp/tests/test_llcorehttp_peer.py | 10 +- indra/newview/llappviewer.cpp | 13 ++ 24 files changed, 702 insertions(+), 163 deletions(-) create mode 100644 indra/llcorehttp/_httpopsetget.cpp create mode 100644 indra/llcorehttp/_httpopsetget.h (limited to 'indra') diff --git a/indra/llcorehttp/CMakeLists.txt b/indra/llcorehttp/CMakeLists.txt index a0827286e3..4273b32fe3 100644 --- a/indra/llcorehttp/CMakeLists.txt +++ b/indra/llcorehttp/CMakeLists.txt @@ -10,12 +10,14 @@ include(OpenSSL) include(ZLIB) include(LLCoreHttp) include(LLAddBuildTest) +include(LLMessage) include(LLCommon) include(Tut) include_directories (${CMAKE_CURRENT_SOURCE_DIR}) include_directories( + ${LLMESSAGE_INCLUDE_DIRS} ${LLCOMMON_INCLUDE_DIRS} ${LLCOREHTTP_INCLUDE_DIRS} ) @@ -31,6 +33,7 @@ set(llcorehttp_SOURCE_FILES _httpopcancel.cpp _httpoperation.cpp _httpoprequest.cpp + _httpopsetget.cpp _httpopsetpriority.cpp _httppolicy.cpp _httppolicyglobal.cpp @@ -54,6 +57,7 @@ set(llcorehttp_HEADER_FILES _httpopcancel.h _httpoperation.h _httpoprequest.h + _httpopsetget.h _httpopsetpriority.h _httppolicy.h _httppolicyglobal.h @@ -113,6 +117,7 @@ if (LL_TESTS) set(test_libs ${LLCOREHTTP_LIBRARIES} ${WINDOWS_LIBRARIES} + ${LLMESSAGE_LIBRARIES} ${LLCOMMON_LIBRARIES} ${GOOGLEMOCK_LIBRARIES} ${CURL_LIBRARIES} 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();

Non-LLThread-based threads need to do some registration or LLMutex locks taken out in these threads will not work as expected (SH-3154). We'll get a better solution later, this fixes some things for now. Tracing of operations now supported. Global and per-request (via HttpOptions) tracing levels of [0..3]. The 2 and 3 levels use libcurl's VERBOSE mode combined with CURLOPT_DEBUGFUNCTION to stream high levels of detail into the log. *Very* laggy but useful. Simple GET request supported (no Range: header). Really just a degenrate case of a ranged get but supplied an API anyway. Global option to use the LLProxy interface to setup CURL handles for either socks5 or http proxy usage. This isn't really the most encapsulated way to do this but a better solution will have to come later. The wantHeaders and tracing options are now supported in HttpOptions giving per-request controls. Big refactoring of the HTTP resource waiter in lltexturefetch. What I was doing before wasn't correct. Instead, I'm implementing the resource wait after the Semaphore model (though not using system semaphores). So instead of having a sequence like: SEND_HTTP_REQ -> WAIT_HTTP_RESOURCE -> SEND_HTTP_REQ, we now do WAIT_HTTP_RESOURCE -> WAIT_HTTP_RESOURCE2 (actual wait) -> SEND_HTTP_REQ. Works well but the prioritized filling of the corehttp library needs some performance work later. --- indra/llcommon/llthread.cpp | 7 + indra/llcommon/llthread.h | 5 + indra/llcorehttp/_httplibcurl.cpp | 24 ++- indra/llcorehttp/_httpoperation.cpp | 15 +- indra/llcorehttp/_httpoperation.h | 4 + indra/llcorehttp/_httpoprequest.cpp | 271 +++++++++++++++++++++------- indra/llcorehttp/_httpoprequest.h | 16 +- indra/llcorehttp/_httpopsetget.cpp | 4 +- indra/llcorehttp/_httppolicy.cpp | 21 ++- indra/llcorehttp/_httppolicy.h | 5 +- indra/llcorehttp/_httppolicyglobal.cpp | 52 ++++-- indra/llcorehttp/_httppolicyglobal.h | 6 +- indra/llcorehttp/_httpservice.cpp | 18 +- indra/llcorehttp/httpoptions.cpp | 18 +- indra/llcorehttp/httpoptions.h | 14 +- indra/llcorehttp/httprequest.cpp | 27 +++ indra/llcorehttp/httprequest.h | 75 +++++++- indra/llcorehttp/tests/test_httprequest.hpp | 228 ++++++++++++++++++++++- indra/newview/llappviewer.cpp | 20 +- indra/newview/lltexturefetch.cpp | 120 +++++++----- indra/newview/lltexturefetch.h | 9 + indra/newview/lltextureview.cpp | 5 +- 22 files changed, 803 insertions(+), 161 deletions(-) (limited to 'indra') diff --git a/indra/llcommon/llthread.cpp b/indra/llcommon/llthread.cpp index a6ad6b125c..b27b64b26f 100644 --- a/indra/llcommon/llthread.cpp +++ b/indra/llcommon/llthread.cpp @@ -71,6 +71,13 @@ LL_COMMON_API void assert_main_thread() } } +void LLThread::registerThreadID() +{ +#if !LL_DARWIN + sThreadID = ++sIDIter; +#endif +} + // // Handed to the APR thread creation function // diff --git a/indra/llcommon/llthread.h b/indra/llcommon/llthread.h index b52e70ab2e..54af41ec59 100644 --- a/indra/llcommon/llthread.h +++ b/indra/llcommon/llthread.h @@ -88,6 +88,11 @@ public: U32 getID() const { return mID; } + // Called by threads *not* created via LLThread to register some + // internal state used by LLMutex.

With this commit, the cleanup paths should be production quality. Unit tests have been expanded to include cases requiring thread termination and cleanup by the worker thread. Special operation/request added to support the unit tests. Thread interface expanded to include a very aggressive cancel() method that does not do cleanup but prevents the thread from accessing objects that will be destroyed. --- indra/llcorehttp/_httplibcurl.cpp | 97 +++++++++++++----- indra/llcorehttp/_httplibcurl.h | 16 +-- indra/llcorehttp/_httpoperation.cpp | 36 +++++++ indra/llcorehttp/_httpoperation.h | 25 +++++ indra/llcorehttp/_httppolicy.cpp | 15 ++- indra/llcorehttp/_httppolicy.h | 15 ++- indra/llcorehttp/_httprequestqueue.h | 6 +- indra/llcorehttp/_httpservice.cpp | 75 ++++++++++---- indra/llcorehttp/_httpservice.h | 11 +- indra/llcorehttp/_thread.h | 20 +++- indra/llcorehttp/httprequest.cpp | 43 ++++++-- indra/llcorehttp/httprequest.h | 9 ++ indra/llcorehttp/tests/test_httprequest.hpp | 154 +++++++++++++++++++++++++++- 13 files changed, 447 insertions(+), 75 deletions(-) (limited to 'indra') diff --git a/indra/llcorehttp/_httplibcurl.cpp b/indra/llcorehttp/_httplibcurl.cpp index 45e16d420e..bc8b3cc9be 100644 --- a/indra/llcorehttp/_httplibcurl.cpp +++ b/indra/llcorehttp/_httplibcurl.cpp @@ -47,12 +47,19 @@ HttpLibcurl::HttpLibcurl(HttpService * service) HttpLibcurl::~HttpLibcurl() { - // *FIXME: need to cancel requests in this class, not in op class. + shutdown(); + + mService = NULL; +} + + +void HttpLibcurl::shutdown() +{ while (! mActiveOps.empty()) { active_set_t::iterator item(mActiveOps.begin()); - (*item)->cancel(); + cancelRequest(*item); (*item)->release(); mActiveOps.erase(item); } @@ -63,8 +70,6 @@ HttpLibcurl::~HttpLibcurl() { if (mMultiHandles[policy_class]) { - // *FIXME: Do some multi cleanup here first - curl_multi_cleanup(mMultiHandles[policy_class]); mMultiHandles[policy_class] = 0; } @@ -73,20 +78,12 @@ HttpLibcurl::~HttpLibcurl() delete [] mMultiHandles; mMultiHandles = NULL; } - - mService = NULL; -} - -void HttpLibcurl::init() -{} - - -void HttpLibcurl::term() -{} + mPolicyCount = 0; +} -void HttpLibcurl::setPolicyCount(int policy_count) +void HttpLibcurl::start(int policy_count) { llassert_always(policy_count <= POLICY_CLASS_LIMIT); llassert_always(! mMultiHandles); // One-time call only @@ -143,8 +140,9 @@ HttpService::ELoopSpeed HttpLibcurl::processTransport() } else { - // *FIXME: Issue a logging event for this. - ; + LL_WARNS_ONCE("CoreHttp") << "Unexpected message from libcurl.

Some additional work let me enable a memory check for the clean shutdown case and generally do a better job on other interfaces. Request queue waiters now awake on shutdown and don't sleep once the queue is turned off. Much better semantically for how this will be used. --- indra/llcorehttp/_httplibcurl.cpp | 8 +- indra/llcorehttp/_httpoperation.cpp | 3 +- indra/llcorehttp/_httppolicy.cpp | 6 +- indra/llcorehttp/_httprequestqueue.cpp | 11 +- indra/llcorehttp/_httprequestqueue.h | 30 ++- indra/llcorehttp/_httpservice.cpp | 43 ++-- indra/llcorehttp/_httpservice.h | 10 +- indra/llcorehttp/_thread.h | 27 ++- indra/llcorehttp/tests/test_httprequest.hpp | 309 ++++++++++++++-------------- 9 files changed, 248 insertions(+), 199 deletions(-) (limited to 'indra') diff --git a/indra/llcorehttp/_httplibcurl.cpp b/indra/llcorehttp/_httplibcurl.cpp index bc8b3cc9be..39abca12c5 100644 --- a/indra/llcorehttp/_httplibcurl.cpp +++ b/indra/llcorehttp/_httplibcurl.cpp @@ -57,11 +57,11 @@ void HttpLibcurl::shutdown() { while (! mActiveOps.empty()) { - active_set_t::iterator item(mActiveOps.begin()); + HttpOpRequest * op(* mActiveOps.begin()); + mActiveOps.erase(mActiveOps.begin()); - cancelRequest(*item); - (*item)->release(); - mActiveOps.erase(item); + cancelRequest(op); + op->release(); } if (mMultiHandles) diff --git a/indra/llcorehttp/_httpoperation.cpp b/indra/llcorehttp/_httpoperation.cpp index b35ab79d65..d80a8236e6 100644 --- a/indra/llcorehttp/_httpoperation.cpp +++ b/indra/llcorehttp/_httpoperation.cpp @@ -235,8 +235,9 @@ void HttpOpSpin::stageFromRequest(HttpService * service) } else { + ms_sleep(1); // backoff interlock plumbing a bit this->addRef(); - if (!
