//////////////////////////////////////////////////////////////////////////////
//
// Introduction
//
// This is an attempt to document what's going on in here after-the-fact.
// It's a sincere attempt to be accurate but there will be mistakes.
//
//
// Purpose
//
// What is this module trying to do? It accepts requests to load textures
// at a given priority and discard level and notifies the caller when done
// (successfully or not). Additional constraints are:
//
// * Support a local texture cache. Don't hit network when possible
// to avoid it.
// * Use UDP or HTTP as directed or as fallback. HTTP is tried when
// not disabled and a URL is available. UDP when a URL isn't
// available or HTTP attempts fail.
// * Asynchronous (using threads). Main thread is not to be blocked or
// burdened.
// * High concurrency. Many requests need to be in-flight and at various
// stages of completion.
// * Tolerate frequent re-prioritizations of requests. Priority is
// a reflection of a camera's viewpoint and as that viewpoint changes,
// objects and textures become more and less relevant and that is
// expressed at this level by priority changes and request cancelations.
//
// The caller interfaces that fall out of the above and shape the
// implementation are:
// * createRequest - Load j2c image via UDP or HTTP at given discard level and priority
// * deleteRequest - Request removal of prior request
// * getRequestFinished - Test if request is finished returning data to caller
// * updateRequestPriority - Change priority of existing request
// * getFetchState - Retrieve progress on existing request
//
// Everything else in here is mostly plumbing, metrics and debug.
//
//
// The Work Queue
//
// The two central classes are LLTextureFetch and LLTextureFetchWorker.
// LLTextureFetch combines threading with a priority queue of work
// requests. The priority queue is sorted by a U32 priority derived
// from the F32 priority in the APIs. The *only* work request that
// receives service time by this thread is the highest priority
// request. All others wait until it is complete or a dynamic priority
// change has re-ordered work.
//
// LLTextureFetchWorker implements the work request and is 1:1 with
// texture fetch requests. Embedded in each is a state machine that
// walks it through the cache, HTTP, UDP, image decode and retry
// steps of texture acquisition.
//
//
// Threads
//
// Several threads are actively invoking code in this module. They
// include:
//
// 1. Tmain Main thread of execution
// 2. Ttf LLTextureFetch's worker thread provided by LLQueuedThread
// 3. Tcurl LLCurl's worker thread (should disappear over time)
// 4. Ttc LLTextureCache's worker thread
// 5. Tid Image decoder's worker thread
// 6. Thl HTTP library's worker thread
//
//
// Mutexes/Condition Variables
//
// 1. Mt Mutex defined for LLThread's condition variable (base class of
// LLTextureFetch)
// 2. Ct Condition variable for LLThread and used by lock/unlockData().
// 3. Mwtd Special LLWorkerThread mutex used for request deletion
// operations (base class of LLTextureFetch)
// 4. Mfq LLTextureFetch's mutex covering request and command queue
// data.
// 5. Mfnq LLTextureFetch's mutex covering udp and http request
// queue data.
// 6. Mwc Mutex covering LLWorkerClass's members (base class of
// LLTextureFetchWorker). One per request.
// 7. Mw LLTextureFetchWorker's mutex. One per request.
//
//
// Lock Ordering Rules
//
// Not an exhaustive list but shows the order of lock acquisition
// needed to prevent deadlocks. 'A < B' means acquire 'A' before
// acquiring 'B'.
//
// 1. Mw < Mfnq
// (there are many more...)
//
//
// Method and Member Definitions
//
// With the above, we'll try to document what threads can call what
// methods (using T* for any), what locks must be held on entry and
// are taken out during execution and what data is covered by which
// lock (if any). This latter category will be especially prone to
// error so be skeptical.
//
// A line like: "// Locks: M<xxx>" indicates a method that must
// be invoked by a caller holding the 'M<xxx>' lock. Similarly,
// "// Threads: T<xxx>" means that a caller should be running in
// the indicated thread.
//
// For data members, a trailing comment like "// M<xxx>" means that
// the data member is covered by the specified lock. Absence of a
// comment can mean the member is unlocked or that I didn't bother
// to do the archaeology. In the case of LLTextureFetchWorker,
// most data members added by the leaf class are actually covered
// by the Mw lock. You may also see "// T<xxx>" which means that
// the member's usage is restricted to one thread (except for
// perhaps construction and destruction) and so explicit locking
// isn't used.
//
// In code, a trailing comment like "// [-+]M<xxx>" indicates a
// lock acquision or release point.
//
//
// Worker Lifecycle
//
// The threading and responder model makes it very likely that
// other components are holding on to a pointer to a worker request.
// So, uncoordinated deletions of requests is a guarantee of memory
// corruption in a short time. So destroying a request involves
// invocations's of LLQueuedThread/LLWorkerThread's abort/stop
// logic that removes workers and puts them ona delete queue for
// 2-phase destruction. That second phase is deferrable by calls
// to deleteOK() which only allow final destruction (via dtor)
// once deleteOK has determined that the request is in a safe
// state.
//
//
// Worker State Machine
//
// (ASCII art needed)
//
//
// Priority Scheme
//
// [PRIORITY_LOW, PRIORITY_NORMAL) - for WAIT_HTTP_RESOURCE state
// and other wait states
// [PRIORITY_HIGH, PRIORITY_URGENT) - External event delivered,
// rapidly transitioning through states,
// no waiting allowed
//
// By itself, the above work queue model would fail the concurrency
// and liveness requirements of the interface. A high priority
// request could find itself on the head and stalled for external
// reasons (see VWR-28996). So a few additional constraints are
// required to keep things running:
// * Anything that can make forward progress must be kept at a
// higher priority than anything that can't.
// * On completion of external events, the associated request
// needs to be elevated beyond the normal range to handle
// any data delivery and release any external resource.
//
// This effort is made to keep higher-priority entities moving
// forward in their state machines at every possible step of
// processing. It's not entirely proven that this produces the
// experiencial benefits promised.

/**
* @brief Base class for cross-thread requests made of the fetcher
*
* I believe the intent of the LLQueuedThread class was to
* have these operations derived from LLQueuedThread::QueuedRequest
* but the texture fetcher has elected to manage the queue
* in its own manner. So these are free-standing objects which are
* managed in simple FIFO order on the mCommands queue of the
* LLTextureFetch object.
*
* What each represents is a simple command sent from an
* outside thread into the TextureFetch thread to be processed
* in order and in a timely fashion (though not an absolute
* higher priority than other operations of the thread).
* Each operation derives a new class from the base customizing
* members, constructors and the doWork() method to effect
* the command.
*
* The flow is one-directional. There are two global instances
* of the LLViewerAssetStats collector, one for the main program's
* thread pointed to by gViewerAssetStatsMain and one for the
* TextureFetch thread pointed to by gViewerAssetStatsThread1.
* Common operations has each thread recording metrics events
* into the respective collector unconcerned with locking and
* the state of any other thread. But when the agent moves into
* a different region or the metrics timer expires and a report
* needs to be sent back to the grid, messaging across threads
* is required to distribute data and perform global actions.
* In pseudo-UML, it looks like:
*
* Main Thread1

*
* Key:
*
* SRE - Set Region Enqueued. Enqueue a 'Set Region' command in
* the other thread providing the new UUID of the region.
* TFReqSetRegion carries the data.
* SR - Set Region. New region UUID is sent to the thread-local
* collector.
* SME - Send Metrics Enqueued. Enqueue a 'Send Metrics' command
* including an ownership transfer of a cloned LLViewerAssetStats.
* TFReqSendMetrics carries the data.
* SM - Send Metrics. Global metrics reporting operation. Takes
* the cloned stats from the command, merges it with the
* thread's local stats, converts to LLSD and sends it on
* to the grid.
* AM - Agent Moved. Agent has completed some sort of move to a
* new region.
* TE - Timer Expired. Metrics timer has expired (on the order
* of 10 minutes).
* CP - CURL Post
* MSC - Modify Stats Collector. State change in the thread-local
* collector. Typically a region change which affects the
* global pointers used to find the 'current stats'.
* RSC - Read Stats Collector. Extract collector data cloning it
* (i.e. deep copy) when necessary.
