2014-09-19Cleanup work. Use http constants for content-type andMonty Brandenberg
accept headers in mesh and textures. For texture metrics reporting, use the AP_INVENTORY policy class which is non-pipelined and pointing (usually) in the right direction. Use a do-while(false) structure to manage common exit path code in onCompleted() methods. Identical to a 'goto' but might amuse the pedantic. Tuning on background fetch to have it cycle faster. This is experimental. I suspect with HTTP balancing in llcorehttp, we can do away with the timers here.
2014-08-22Add an HTTP policy class for inventory operations using four (4)Monty Brandenberg
connections. Convert background and foreground fetches, both items and folders/inventory and library, to use new HTTP. Non-fetch inventory operations continue to use LLHTTPClient (at least for now). Error handling and retry on fetches wasn't 100% previously and that's still the case. I'll rip through this again to clean that up. Cleaned up logging in much of the inventory code with consistent labels on logging events and correct macros (removed deprecation warnings). This started as an attempt to get libcurl to do pipelining on POSTs and PUTs. Discovered that this is going to be very difficult to support in general in libcurl. May look at that again in the future.
2014-08-12Better support for dynamic option changes in llcorehttp. Libcurl hasMonty Brandenberg
some problems disabling pipelining on a multi handle with outstanding requests so build a more conservative system that allows requests to drain before setting curl multi options. Would rather not have this but it is significantly safer. "HttpPipelining" debug setting is now fully dynamic. Connection limits can also be made dynamic in the near future. Upped the default connection count back to 8 for now but will revisit this in the tuning phase. It might be time to combine mesh and textures into a single asset class. For normal server operations that would be a clear path, but for server under load, the current scheme may be better. Minor cleanup in logging to elminate some redundant strings. Might add some more tracing to the stall logic 'just in case'.
2014-06-23First HTTP pipelining viewer. Enable pipelining forMonty Brandenberg
GetTexture and GetMesh2 at a pipeline depth of 5. Create global debug option, HttpPipelining, to enable and disable HTTP pipelining (defaults to true). Tweak texture and mesh low- and high-water request levels based on pipelining status and depth. Fixup texture console which was damaged in a recent release. Split logging of the no-request HTTP error case into two cases: one for missing URL in HTTP request, one for HTTP request not created. A refactor in llcorehttp is coming: I will be moving all libcurl- using code into libcurl-specific modules.
2013-09-18SH-4492 Create a useful README for llcorehttpMonty Brandenberg
Last bit for this release. Describe stream adapters and how to select a policy class. Slight changes to setup code to make reality reflect documentation.
2013-06-28SH-4312 Clumsy configuration coordination between mesh and corehttpMonty Brandenberg
Taught llappcorehttp to register signals on the settings values that chagne behavior. Have initialization and settings changes sweep through settings and change them. Dynamic changes are tried but have no effect (produce a warning message) as dynamic settings still aren't supported but the plumbing is now connected. Just need to change llcorehttp. Bounced the 'teleport started' signal around and it ended up back where it started with some cleanup. This is making me less angry...
2013-06-20SH-4257 Preparation for a new cap grant: GetMesh2Monty Brandenberg
Mesh repo is using three policy classes now: one for large objects, one for GetMesh2 regions, one for GetMesh regions. It's also detecting the presence of the cap and using the correct class. Class initialization cleaned up significantly in llappcorehttp using data-directed code. Pulled in the changes to HttpHeader done for sunshine-internal then did a refactoring pass on the header callback which now uses a unified approach to clean up and deliver header information to all interested parties. Added support for using Retry-After header information on 503 retries.
2013-06-19SH-4252 Add second policy class for large mesh asset downloadsMonty Brandenberg
Added second mesh class as well as an asset upload class. Refactored initialization to use less code and more data to cleanly get http started. Modified mesh to use the new http class for large requests (>2MB for now). Added additional timeout setting to llcorehttp to distinguish connection timeout from transport timeout and are now using transport timeout values for large asset downloads that may need more time.

2013-05-07SH-4139 Convert http downloaders and responders to llcorehttp patternsMonty Brandenberg
Initial work completed on linux, moving over to windows to do debug and refinement. This includes 5/6 handlers based on existing responders and use of llcorehttp for the mesh header fetch.

2012-07-19SH-3280 Better init/shutdown functionality for llcorehttp by llappviewerMonty Brandenberg
Isolate llcorehttp initialization into a utility class (LLAppCoreHttp) that provides glue between app and library (sets up policies, handles notifications). Introduce 'TextureFetchConcurrency' debug setting to provide some field control when absolutely necessary.
