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.
as transfers can appear delayed with deep pipelining and more
requests in the pool. Added bad HTTP status error (typically
getting a 0 back as HTTP status from libcurl) to the list of
retryable errors. There's a response stream problem with libcurl
and pipelining that induces this problem. Retrying helps but
may not be entirely safe. Watch bug 1420 on the libcurl sourceforge
bug tracker. Extend options of test/example program to include
un-ranged requests. Document the excessive data transfer induced
when ranged requests are disabled. This is an abnormal mode for
very rare users so we'll just eat that for now.
Intended for users with bad networking gear or twitchy ISPs, if set to
True, forces plain GET requests to asset servers for textures and meshes.
This change kicked off a slight refactor in the mesh repository code which
made it resilient against unexpected 200's and responses not covering
the requested start range. There's still too much data copying in the
Mesh code (always has been). Would love to fix that and get rid of the
monolithic temp buffer. Cleaned up white space damage caused by unnamed

data so their isn't an opportunity for gaps over overruns (init_data).
Start some preliminary tweaking of policy class numbers. It looks
like I can easily drop the default connection count to '4' and
still hit the throttles. Did some experiments running pipeline
deeper which was mostly fine for textures but tended to slow
meshes. Reason uncertain but a depth of '5' seems generally healthy
for mesh. I had one run of 52.6S with a theoretical minimum of 51.2S.
That's as good as I've ever seen.
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.
