2012-06-15Ported example (freestanding) program to drive API & generate performance ↵Monty Brandenberg
numbers. This is a command-line utility to pull content down from a service through the llcorehttp library to produce timings and resource footprints.
2012-06-14LLMutex recursive lock, global & per-request tracing, simple GET request, ↵Monty Brandenberg
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.
2012-06-13Restore original priority scheme of LOW/HIGH.Monty Brandenberg
The NORMAL range doesn't do any sleeping at all and so we'll spin the core harder than we already are. Bring all idlers into the same range.
2012-06-12Really need to figure out the 'static const' problem on Windows.Monty Brandenberg
For now, workaround...
2012-06-12HTTP Proxy, PUT & POST, unit tests and refactoring.Monty Brandenberg
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).
2012-06-12Convert _refcounted.h over to using LLAtomic32<>.Monty Brandenberg
Beware of bad documentation. operator--(int) does not return what the header claimed it did.
2012-06-11Bring in the testrunner/http server scaffold for better integration testing.Monty Brandenberg
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'.
2012-06-11Convert BufferArray interfaces to void * (not char *). ↵Monty Brandenberg
HttpRequest::update() honor time limit. Generally, opaque data operations are expected to be over 'void *' and have now converted interfaces to do that. Update() method honors millisecond limit to dwell time. Might want to homologate the millis/uSecs mix later....
2012-06-11Refactoring of the request completion thread and removal of ↵Monty Brandenberg
206/content-range hack in xport. Retry/response handling is decided in policy so moved that there. Removed special case 206-without-content-range response in transport. Have this sitation recognizable in the API and let callers deal with it as needed.
2012-06-11Unit test fixups. Mac/Linux detect memory leak due to llwarns, try/catch ↵Monty Brandenberg
cleanup. Our logging holds on to a changing bit of memory between operations and the memory leak detection I'm using senses this and complains. So, for now, disable the final memory check on Mac & Linux, leave it active on Windows. Solve this for real some other day. Add try/catch blocks to do cleanup in unit tests that go wrong so that we don't get a cascade of assertion failures when subsequent tests find singletons still alive.

2012-06-08Implemented HTTP retry for requests. Went in rather easily whichMonty Brandenberg
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. People won't like this but tough, need tests.

2012-06-07First efforts at getting the texture cache working. This isMonty Brandenberg
now avoiding doing HTTP fetches for read data. Not certain it's completely correct but the difference is already significant.
2012-06-07Lock/Mutex fixes, documentation, new resource wait state, dtor cleanupsMonty Brandenberg
Went through all the code and tried to document lock and thread usage in the module. 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.

2012-06-06MAINT-1144: Re-enable skipped LLHTTPClient tests with local server.Nat Goodspeed
Over the years we've skipped more and more of the tests in llhttpclient_test.cpp (nee llhttpclient_tut.cpp) because they've relied on particular behaviors from Internet sites not under our control. We skipped a test that fetches llsd+xml from secondlife.com because "secondlife.com is not reliable enough for unit tests." We skipped a test that tries to observe a failure with "http://www.invalid" because some local ISPs turn "no such domain" DNS errors into valid pages offering the requester to buy the specified domain name. Today we've had to skip tests attempting to contact "http://www.google.com" for reasons we haven't yet diagnosed, but that probably have to do with Google's IPv6 rollout. Use local temp server test_llsdmessage_peer.py as the success destination, eliminating DNS, Internet access and remote server behavior as failure modes. Use idle localhost port for failure test. Re-enable all skipped LLHTTPClient tests! Re-enable on Windows! In support of these tests, modify test_llsdmessage_peer.py: Support HEAD as no-data variant of GET. Change GET result dict to avoid resembling an error response -- confusing. Make GET/POST return actual dict rather than undecorated string "success". Because of that last, change llcapabilitylistener_test.cpp and llsdmessage_test.cpp to extract "reply" key from response rather than expecting response to be a string itself.

indra/test/llhttpclient_tut.cpp ==> indra/llmessage/tests/llhttpclient_test.cpp, with corresponding CMakeLists.txt changes in their respective directories. This first commit merely moves the test source file without changing it -- separating out moves from edits simplifies code review.
2012-06-06MAINT-1144: Unblock build for previous commit.Nat Goodspeed
Today, 2012-06-06, LLHTTPClient::get("http://www.google.com/") has stopped working. This is unrelated to viewer code changes: it crosses repo boundaries. Skip the afflicted tests to get builds working until we can recast the tests to avoid the flaky dependency.
2012-06-06MAINT-1144: Defend against NULL LLPluginProcessParent::mProcess.Nat Goodspeed
The change from LLProcessLauncher to LLProcess introduces the possibility of a NULL (default-constructed) LLProcessPtr. Add certain static LLProcess methods accepting LLProcessPtr, forwarding to nonstatic method when non-NULL but doing something reasonable with NULL. Use these methods in LLPLuginProcessParent.

2012-06-06Policy + caching fixes + https support + POST workingMonty Brandenberg
Implemented first global policy definitions to support SSL CA certificate configuration to support https: operations. Fixed HTTP 206 status handling to match what is currently being done by grid services and to lay a foundation for fixes that will be a response to ER-1824. More libcurl CURLOPT options set on easy handles to do peer verification in the traditional way. HTTP POST working and now reporting asset metrics back to grid for the viewer's asset system. This uses LLSD so that is also showing as compatible with the new library.

2012-06-01Major steps towards implementing the policy component.Monty Brandenberg
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.
