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.
2012-06-06Policy + 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.

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.
