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.
2014-08-12Better 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.

2013-04-15SH-4106 Significantly upgrade the HttpHeaders interface for SSB.Monty Brandenberg
Header container moves from a vector of raw lines to a vector of string pairs representing name/value pairs in headers. For incoming headers, we normalize the name to lowercase and trim it. Values are only left-trimmed. Outgoing headers are left as-is. Simple find() method for the common case, forward and reverse iterators for those few who need to do it themselves. The HTTP status line (e.g. 'HTTP/1.1 200 Ok') is no longer treated as a header to be returned to caller. Unit tests, as usual, were a bear but they absolutely ensured outgoing HTTP header conformance after the change. Grunt work paid off. LLTextureFetch was also given a second options structure for texture fetches. Same as the original but with header return to caller requested. Baked textures should use this, the other 20,000 texture fetch requests should continue to use the original.

http phase 1 Some missing counter initialization kept the debugger from entering the startup state giving the appearance of a do- nothing floater. Also found some unbound recursion that might need looking at in the future. (There's a comment.)

2012-08-21SH-3325 texture load slow on some machinesMonty Brandenberg
This doesn't really address 3325 directly but it is the result of research done while hunting it down. First, this is a thread safety improvement for canceled requests that have gone into resource wait state. I don't think we've seen a failure there but there was a window. It also cleans the resource wait queue earlier which lets us do less work and get requests more quickly into llcorehttp by bypassing the resource wait state. With this, I finally feel comfortable about rundown of requests.
2012-08-19SH-3329 Cached scene loads slower than same scene with cleared cache.Monty Brandenberg
A/B comparison with original code showed the newer issuing lower-priority requests of the cache reader and some other minor changes. Brought them into agreement (this is cargo-cult programming). Made the HTTP resource semaphore an atomic int for rigorous correctness across threads. I swear I'm going to tear down this code someday.

Dropped an argument during integration which made the total byte count read lower than expected. Everything else is fine, however.

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.

Big delta was converting the new texture debugger support code to the new library. Viewer manifest should probably get an eyeball before release.

log on exit. With much trial-and-error, cleaned up the banner on the texture console and made everything mostly fit. Added global cache read, cache write and resource wait count events to the console display to show if cache is working. On clean exit, emit a log line to report stats to log file (intended for automated tests, maybe): LLTextureFetch::endThread: CacheReads: 2618, CacheWrites: 117, ResWaits: 0, TotalHTTPReq: 117
