+// If you find this included in a public interface header,
+// something wrong is probably happening.
+
+
+// --------------------------------------------------------------------
+// General library to-do list
+//
+// - Implement policy classes.  Structure is mostly there just didn't
+//   need it for the first consumer.
+// - Consider Removing 'priority' from the request interface.  Its use
+//   in an always active class can lead to starvation of low-priority
+//   requests.  Requires coodination of priority values across all
+//   components that share a class.  Changing priority across threads
+//   is slightly expensive (relative to gain) and hasn't been completely
+//   implemented.  And the major user of priority, texture fetches,
+//   may not really need it.
+// - Set/get for global policy and policy classes is clumsy.  Rework
+//   it heading in a direction that allows for more dynamic behavior.
+// - Move HttpOpRequest::prepareRequest() to HttpLibcurl for the
+//   pedantic.
+// - Update downloader and other long-duration services are going to
+//   need a progress notification.  Initial idea is to introduce a
+//   'repeating request' which can piggyback on another request and
+//   persist until canceled or carrier completes.  Current queue
+//   structures allow an HttpOperation object to be enqueued
+//   repeatedly, so...
+// - Investigate making c-ares' re-implementation of a resolver library
+//   more resilient or more intelligent on Mac.  Part of the DNS failure
+//   lies in here.  The mechanism also looks a little less dynamic
+//   than needed in an environments where networking is changing.
+// - Global optimizations:  'borrowing' connections from other classes,
+//   HTTP pipelining.
+// - Dynamic/control system stuff:  detect problems and self-adjust.
+//   This won't help in the face of the router problems we've looked
+//   at, however.  Detect starvation due to UDP activity and provide
+//   feedback to it.
+//
+// Integration to-do list
+// - LLTextureFetch still needs a major refactor.  The use of
+//   LLQueuedThread makes it hard to inspect workers and do the
+//   resource waiting we're now doing.  Rebuild along simpler lines
+//   some of which are suggested in new commentary at the top of
+//   the main source file.
+// - Expand areas of usage eventually leading to the removal of LLCurl.
+//   Rough order of expansion:
+//   .  Mesh fetch
+//   .  Avatar names
+//   .  Group membership lists
+//   .  Caps access in general
+//   .  'The rest'
+// - Adapt texture cache, image decode and other image consumers to
+//   the BufferArray model to reduce data copying.  Alternatively,
+//   adapt this library to something else.
+//
+// --------------------------------------------------------------------
+
+
+// If '1', internal ready queues will not order ready
+// requests by priority, instead it's first-come-first-served.

+/// then activated issuing HTTP requests and moved to an
+/// active list managed by the transport (libcurl) component
+/// and eventually finalized when a response is available
+/// and status and data return via reply queue.
+///
+/// To manage these transitions, derived classes implement
+/// three methods:  stageFromRequest, stageFromReady and
+/// stageFromActive.  Immediate requests will only override
+/// stageFromRequest which will perform the operation and

+/// be the most time efficient implementation and it is a little
+/// challenging.
+///
+/// BufferArrayStream inherits std::iostream and will be the
+/// adapter object most callers will be interested in (though
+/// it uses BufferArrayStreamBuf internally).  Instances allow
+/// for the usual streaming operators ('<<', '>>') and serialization
+/// methods.
+///
+/// Example of LLSD serialization to a BufferArray:
+///
+///   BufferArray * ba = new BufferArray;
+///   BufferArrayStream bas(ba);
+///   LLSDSerialize::toXML(llsd, bas);
+///   operationOnBufferArray(ba);
+///   ba->release();
+///   ba = NULL;
+///   // operationOnBufferArray and bas are each holding
+///   // references to the ba instance at this point.

+
+/// @package LLCore::HTTP
+///
+/// This library implements a high-level, Indra-code-free client interface to
+/// HTTP services based on actual patterns found in the viewer and simulator.
+/// Interfaces are similar to those supplied by the legacy classes
+/// LLCurlRequest and LLHTTPClient.  To that is added a policy scheme that
+/// allows an application to specify connection behaviors:  limits on
+/// connections, HTTP keepalive, HTTP pipelining, retry-on-error limits, etc.
+///
+/// Features of the library include:
+/// - Single, private working thread where all transport and processing occurs.
+/// - Support for multiple consumers running in multiple threads.
+/// - Scatter/gather (a.k.a. buffer array) model for bulk data movement.
+/// - Reference counting used for many object instance lifetimes.
+/// - Minimal data sharing across threads for correctness and low latency.
+/// 
+/// The public interface is declared in a few key header files:
+/// - "llcorehttp/bufferarray.h"
+/// - "llcorehttp/httpcommon.h"
+/// - "llcorehttp/httphandler.h"
+/// - "llcorehttp/httpheaders.h"
+/// - "llcorehttp/httpoptions.h"
+/// - "llcorehttp/httprequest.h"
+/// - "llcorehttp/httpresponse.h"
+///
+/// The library is still under early development and particular users
+/// may need access to internal implementation details that are found
+/// in the _*.h header files.  But this is a crutch to be avoided if at
+/// all possible and probably indicates some interface work is neeeded.
+///
+/// Using the library is fairly easy.  Global setup needs a few
+/// steps:
+///
+/// - libcurl initialization including thread-safely callbacks for SSL:
+///   .  curl_global_init(...)
+///   .  CRYPTO_set_locking_callback(...)
+///   .  CRYPTO_set_id_callback(...)
+/// - HttpRequest::createService() called to instantiate singletons
+///   and support objects.
+///
+/// An HTTP consumer in an application, and an application may have many
+/// consumers, does a few things:
+///
+/// - Instantiate and retain an object based on HttpRequest.  This
+///   object becomes the portal into runtime services for the consumer.
+/// - Derive or mixin the HttpHandler class if you want notification
+///   when requests succeed or fail.  This object's onCompleted()
+///   method is invoked and an instance can be shared across
+///   requests.
+///
+/// Issuing a request is straightforward:
+/// - Construct a suitable URL.
+/// - Configure HTTP options for the request.  (optional)
+/// - Build a list of additional headers.  (optional)
+/// - Invoke one of the requestXXXX() methods (requestGetByteRange,
+///   requestPost, etc.) on the HttpRequest instance supplying the
+///   above along with a policy class, a priority and an optional
+///   pointer to an HttpHandler instance.  Work is then queued to
+///   the worker thread and occurs asynchronously.
+/// - Periodically invoke the update() method on the HttpRequest
+///   instance which performs completion notification to HttpHandler
+///   objects.
+/// - Do completion processing in your onCompletion() method.
+///
+/// Code fragments:
+/// Rather than a poorly-maintained example in comments, look in the
+/// example subdirectory which is a minimal yet functional tool to do
+/// GET request performance testing.  With four calls:
+///
+///   	init_curl();
+///     LLCore::HttpRequest::createService();
+///     LLCore::HttpRequest::startThread();
+///     LLCore::HttpRequest * hr = new LLCore::HttpRequest();
+///
+/// the program is basically ready to issue requests.

+/// HttpRequest supplies the entry into the HTTP transport

+///
+/// - Some, but not all, global initialization of libcurl.
+/// - Starting asynchronous, threaded HTTP requests.
+/// - Definition of policy classes affect request handling.
+/// - Utilities to control request options and headers
+///
+/// Requests
+///
+/// The class supports the current HTTP request operations:
+///
+/// - requestGetByteRange:  GET with Range header for a single range of bytes
+///
+/// Policy Classes
+///
+/// <TBD>
+///
+/// Usage
+///
+/// <TBD>
+///
+/// Threading:  An instance may only be used by one application/
+/// consumer thread.  But a thread may have as many instances of
+/// this as it likes.
+///
+/// Allocation:  Not refcounted, may be stack allocated though that
+/// hasn't been tested.  Queued requests can still run and any
+/// queued replies will keep refcounts to the reply queue leading
+/// to memory leaks.
+///
+/// @pre Before using this class (static or instances), some global
+/// initialization is required.  See @see httpcommon.h for more information.

+    Find a free server port to use. Specifically, evaluate 'expr' (a
+    callable(port)) until it stops raising EADDRINUSE exception.
+
+    Pass:
+
+    portlist: an iterable (e.g. xrange()) of ports to try. If you exhaust the
+    range, freeport() lets the socket.error exception propagate. If you want
+    unbounded, you could pass itertools.count(baseport), though of course in
+    practice the ceiling is 2^16-1 anyway. But it seems prudent to constrain
+    the range much more sharply: if we're iterating an absurd number of times,
+    probably something else is wrong.
+
+    expr: a callable accepting a port number, specifically one of the items
+    from portlist. If calling that callable raises socket.error with
+    EADDRINUSE, freeport() retrieves the next item from portlist and retries.
+
+    Returns: (expr(port), port)
+
+    port: the value from portlist for which expr(port) succeeded
+
+    Raises:
+
+    Any exception raised by expr(port) other than EADDRINUSE.
+
+    socket.error if, for every item from portlist, expr(port) raises
+    socket.error. The exception you see is the one from the last item in
+    portlist.
+
+    StopIteration if portlist is completely empty.
