This really extended into the client-side request throttling.
Moved this from llmeshrepository (which doesn't really want
to do connection management) into llcorehttp. It's now a
class option with configurable rate. This still isn't the
right thing to do as it creates coupling between viewer
and services. When we get to pipelining, this notion becomes
invalid.
Much improved. Unified the global and class options into a single
option list. Implemented static and dynamic setting paths as much
as possible. Dynamic path does require packet/RPC but otherwise
there's near unification. Dynamic modes can't get values back yet
due to the response/notifier scheme but this doesn't bother me.
Flatten global and class options into simpler struct-like entities.
Setter/getter available on these when needed (external APIs) but code
can otherwise fiddle directly when it knows what to do. Much duplicated
options/state removed from HttpPolicy. Comments cleaned up. Threads
better described and consistently mentioned in API docs. Integration
test extended for 503 responses with Reply-After headers.
Groundwork is used for the default class which currently represents
texture fetching. Class options implemented from API user into
HttpLibcurl. Policy layer is going to start doing some traffic
shaping like work to solve problems with consumer-grade gear.
Need to have dynamic aspects to policies and that starts now...
