2012-07-16SH-3189 Remove/improve naive data structuresMonty Brandenberg
When releasing HTTP waiters, avoid unnecessary sort activity. For Content-Type in responses, let libcurl do the work and removed my parsing of headers. Drop Content-Encoding as libcurl will deal with that. If anyone is interested, they can parse.
2012-07-11SH-3240 Capture Content-Type and Content-Encoding headers.Monty Brandenberg
HttpResponse object now has two strings for these content headers. Either or both may be empty. Tidied up the cross-platform string code and got more defensive about the length of a header line. Integration test for the new response object.

Also added some comments and changed the callback userdata argument to be an HttpOpRequest rather than a libcurl handle. Less code, less clutter.

2012-06-19Implement timeout and retry count options for requests.Monty Brandenberg
Pretty straightforward. Still don't like how I'm managing the options block. Struct? Accessors? Can't decide. But the options now speed up the unit test runs even as I add tests.

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.
2012-06-12HTTP 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).
2012-06-08Implemented 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.

2012-06-01Major 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.
2012-05-23Integrate llcorehttp library into lltexturefetch design.Monty Brandenberg
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.

hard stall while allocating the first easy handle in a descent of the global initiailization code but that doesn't seem to be a problem on TC machines. Perhaps the static linking is creating multiple data copies. More work needed.

The unit/integration tests don't work yet as I'm still battling cmake/autobuild as usual but first milestone passed.
