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 ++++++++++++++++++++++++++++ 18 files changed, 518 insertions(+), 108 deletions(-) create mode 100644 indra/llcorehttp/_httpopcancel.cpp create mode 100644 indra/llcorehttp/_httpopcancel.h (limited to 'indra/llcorehttp') 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 +- 23 files changed, 769 insertions(+), 140 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/llcorehttp') 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.

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. People won't like this but tough, need tests. --- indra/llcorehttp/_httplibcurl.cpp | 58 ++++++++++++++--- indra/llcorehttp/_httplibcurl.h | 4 +- indra/llcorehttp/_httpoprequest.cpp | 51 ++++++++++++--- indra/llcorehttp/_httpoprequest.h | 5 ++ indra/llcorehttp/_httppolicy.cpp | 98 +++++++++++++++++++++-------- indra/llcorehttp/_httppolicy.h | 19 +++++- indra/llcorehttp/_httpreadyqueue.h | 2 - indra/llcorehttp/_httpretryqueue.h | 94 +++++++++++++++++++++++++++ indra/llcorehttp/httpcommon.h | 12 ++++ indra/llcorehttp/tests/test_httprequest.hpp | 2 +- 10 files changed, 296 insertions(+), 49 deletions(-) create mode 100644 indra/llcorehttp/_httpretryqueue.h (limited to 'indra/llcorehttp') diff --git a/indra/llcorehttp/_httplibcurl.cpp b/indra/llcorehttp/_httplibcurl.cpp index 5272c391e8..05b2c2be69 100644 --- a/indra/llcorehttp/_httplibcurl.cpp +++ b/indra/llcorehttp/_httplibcurl.cpp @@ -29,6 +29,7 @@ #include "httpheaders.h" #include "bufferarray.h" #include "_httpoprequest.h" +#include "_httppolicy.h" namespace LLCore @@ -85,6 +86,8 @@ void HttpLibcurl::term() HttpService::ELoopSpeed HttpLibcurl::processTransport() { + HttpService::ELoopSpeed ret(HttpService::REQUEST_SLEEP); + // Give libcurl some cycles to do I/O & callbacks for (int policy_class(0); policy_class < HttpRequest::POLICY_CLASS_LIMIT; ++policy_class) { @@ -110,7 +113,8 @@ HttpService::ELoopSpeed HttpLibcurl::processTransport() CURL * handle(msg->easy_handle); CURLcode result(msg->data.result); - completeRequest(mMultiHandles[policy_class], handle, result); + HttpService::ELoopSpeed speed(completeRequest(mMultiHandles[policy_class], handle, result)); + ret = (std::min)(ret, speed); handle = NULL; // No longer valid on return } else if (CURLMSG_NONE == msg->msg) @@ -127,7 +131,11 @@ HttpService::ELoopSpeed HttpLibcurl::processTransport() } } - return mActiveOps.empty() ?

This brings in a copy of llmessage's llsdmessage testing server. 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. Later will add a dead port as well so we can test that rather than use 'localhost:2'. --- indra/llcorehttp/CMakeLists.txt | 2 + indra/llcorehttp/tests/llcorehttp_test.cpp | 36 ++++ indra/llcorehttp/tests/llcorehttp_test.h | 5 + indra/llcorehttp/tests/test_httprequest.hpp | 119 ++++++++++- indra/llcorehttp/tests/test_llcorehttp_peer.py | 146 ++++++++++++++ indra/llcorehttp/tests/testrunner.py | 262 +++++++++++++++++++++++++ 6 files changed, 568 insertions(+), 2 deletions(-) create mode 100644 indra/llcorehttp/tests/test_llcorehttp_peer.py create mode 100644 indra/llcorehttp/tests/testrunner.py (limited to 'indra/llcorehttp') diff --git a/indra/llcorehttp/CMakeLists.txt b/indra/llcorehttp/CMakeLists.txt index 3fda524ddf..a0827286e3 100644 --- a/indra/llcorehttp/CMakeLists.txt +++ b/indra/llcorehttp/CMakeLists.txt @@ -125,6 +125,8 @@ if (LL_TESTS) LL_ADD_INTEGRATION_TEST(llcorehttp "${llcorehttp_TEST_SOURCE_FILES}" "${test_libs}" + ${PYTHON_EXECUTABLE} + "${CMAKE_CURRENT_SOURCE_DIR}/tests/test_llcorehttp_peer.py" ) endif (LL_TESTS) diff --git a/indra/llcorehttp/tests/llcorehttp_test.cpp b/indra/llcorehttp/tests/llcorehttp_test.cpp index 2d48bca443..f59361ab53 100644 --- a/indra/llcorehttp/tests/llcorehttp_test.cpp +++ b/indra/llcorehttp/tests/llcorehttp_test.cpp @@ -27,6 +27,7 @@ #include "llcorehttp_test.h" #include +#include // These are not the right way in viewer for some reason: // #include @@ -130,3 +131,38 @@ void ssl_locking_callback(int mode, int type, const char * /* file */, int /* li } +std::string get_base_url() +{ + const char * env(getenv("LL_TEST_PORT")); + + if (! env) + { + std::cerr << "LL_TEST_PORT environment variable missing." << std::endl; + std::cerr << "Test expects to run in test_llcorehttp_peer.py script." << std::endl; + tut::ensure("LL_TEST_PORT set in environment", NULL != env); + } + + int port(atoi(env)); + std::ostringstream out; + out << "http://localhost:" << port << "/"; + return out.str(); +} + + +void stop_thread(LLCore::HttpRequest * req) +{ + if (req) + { + req->requestStopThread(NULL); + + int count = 0; + int limit = 10; + while (count++ < limit && !

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 +- 23 files changed, 689 insertions(+), 163 deletions(-) create mode 100644 indra/llcorehttp/_httpopsetget.cpp create mode 100644 indra/llcorehttp/_httpopsetget.h (limited to 'indra/llcorehttp') 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/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 ++++++++++++++++++++++- 16 files changed, 691 insertions(+), 107 deletions(-) (limited to 'indra/llcorehttp') diff --git a/indra/llcorehttp/_httplibcurl.cpp b/indra/llcorehttp/_httplibcurl.cpp index e134a28401..a176dd5b2a 100644 --- a/indra/llcorehttp/_httplibcurl.cpp +++ b/indra/llcorehttp/_httplibcurl.cpp @@ -159,6 +159,17 @@ void HttpLibcurl::addOp(HttpOpRequest * op) curl_multi_add_handle(mMultiHandles[op->mReqPolicy], op->mCurlHandle); op->mCurlActive = true; + if (op->mTracing > 0) + { + HttpPolicy & policy(mService->getPolicy()); + + LL_INFOS("CoreHttp") << "TRACE, ToActiveQueue, Handle: " + << static_cast(op) + << ", Actives: " << mActiveOps.size() + << ", Readies: " << policy.getReadyCount(op->mReqPolicy) + << LL_ENDL; + } + // On success, make operation active mActiveOps.insert(op); } @@ -190,10 +201,9 @@ bool HttpLibcurl::completeRequest(CURLM * multi_handle, CURL * handle, CURLcode // Deactivate request op->mCurlActive = false; - // Set final status of request + // Set final status of request if it hasn't failed by other mechanisms yet if (op->mStatus) { - // Only set if it hasn't failed by other mechanisms yet op->mStatus = HttpStatus(HttpStatus::EXT_CURL_EASY, status); } if (op->mStatus) @@ -209,6 +219,16 @@ bool HttpLibcurl::completeRequest(CURLM * multi_handle, CURL * handle, CURLcode curl_easy_cleanup(handle); op->mCurlHandle = NULL; + // Tracing + if (op->mTracing > 0) + { + LL_INFOS("CoreHttp") << "TRACE, RequestComplete, Handle: " + << static_cast(op) + << ", Status: " << op->mStatus.toHex() + << LL_ENDL; + } + + // Dispatch to next stage HttpPolicy & policy(mService->getPolicy()); bool still_active(policy.stageAfterCompletion(op)); diff --git a/indra/llcorehttp/_httpoperation.cpp b/indra/llcorehttp/_httpoperation.cpp index b5c58013d4..5a31bf90e7 100644 --- a/indra/llcorehttp/_httpoperation.cpp +++ b/indra/llcorehttp/_httpoperation.cpp @@ -34,6 +34,8 @@ #include "_httpreplyqueue.h" #include "_httpservice.h" +#include "lltimer.h" + namespace LLCore { @@ -49,8 +51,10 @@ HttpOperation::HttpOperation() mReplyQueue(NULL), mUserHandler(NULL), mReqPolicy(HttpRequest::DEFAULT_POLICY_ID), - mReqPriority(0U) + mReqPriority(0U), + mTracing(0) { + mMetricCreated = totalTime(); } @@ -113,7 +117,7 @@ void HttpOperation::stageFromActive(HttpService *) llassert_always(false); } - + void HttpOperation::visitNotifier(HttpRequest *) { if (mUserHandler) @@ -138,6 +142,13 @@ HttpStatus HttpOperation::cancel() void HttpOperation::addAsReply() { + if (mTracing > 0) + { + LL_INFOS("CoreHttp") << "TRACE, ToReplyQueue, Handle: " + << static_cast(this) + << LL_ENDL; + } + if (mReplyQueue) { addRef(); diff --git a/indra/llcorehttp/_httpoperation.h b/indra/llcorehttp/_httpoperation.h index c93aa2def9..de4939a0ac 100644 --- a/indra/llcorehttp/_httpoperation.h +++ b/indra/llcorehttp/_httpoperation.h @@ -110,6 +110,10 @@ public: // Reply Data HttpStatus mStatus; + + // Tracing, debug and metrics + HttpTime mMetricCreated; + int mTracing; }; // end class HttpOperation diff --git a/indra/llcorehttp/_httpoprequest.cpp b/indra/llcorehttp/_httpoprequest.cpp index e2550d057e..f78971d8f2 100644 --- a/indra/llcorehttp/_httpoprequest.cpp +++ b/indra/llcorehttp/_httpoprequest.cpp @@ -63,6 +63,16 @@ int parse_content_range_header(char * buffer, unsigned int * last, unsigned int * length); + +// Take data from libcurl's CURLOPT_DEBUGFUNCTION callback and +// escape and format it for a tracing line in logging.

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/llcorehttp') 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.
