From b08125a5874a89ce5210f8fb2c961ae17fb80fde Mon Sep 17 00:00:00 2001 From: Monty Brandenberg Date: Thu, 14 Jun 2012 16:31:48 -0400 Subject: LLMutex recursive lock, global & per-request tracing, simple GET request, LLProxy support, HttpOptions starting to work, HTTP resource waiting fixed. 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 ++++++++++++++++++++++-- 1 file changed, 22 insertions(+), 2 deletions(-) (limited to 'indra/llcorehttp/_httplibcurl.cpp') 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)); -- cgit v1.2.3
