+// The original source for this code is the server repositories'

+// code to libraries was complete.  Rather than add to merge issues,
+// the needed code was cut'n'pasted into this new header as it isn't
+// too awful a burden.  Post-modularization, we can look at removing
+// this redundancy.

+
+/**
+ * @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:

+/*
+ * Classes and utility functions for per-thread and per-region
+ * asset and experiential metrics to be aggregated grid-wide.
+ *
+ * The basic metrics grouping is LLViewerAssetStats::PerRegionStats.
+ * This provides various counters and simple statistics for asset
+ * fetches binned into a few categories.  One of these is maintained
+ * for each region encountered and the 'current' region is available
+ * as a simple reference.  Each thread (presently two) interested
+ * in participating in these stats gets an instance of the
+ * LLViewerAssetStats class so that threads are completely
+ * independent.
+ *
+ * The idea of a current region is used for simplicity and speed
+ * of categorization.  Each metrics event could have taken a
+ * region uuid argument resulting in a suitable lookup.  Arguments
+ * against this design include:
+ *
+ *  -  Region uuid not trivially available to caller.
+ *  -  Cost (cpu, disruption in real work flow) too high.
+ *  -  Additional precision not really meaningful.
+ *
+ * By itself, the LLViewerAssetStats class is thread- and
+ * viewer-agnostic and can be used anywhere without assumptions
+ * of global pointers and other context.  For the viewer,
+ * a set of free functions are provided in the namespace
+ * LLViewerAssetStatsFF which *do* implement viewer-native
+ * policies about per-thread globals and will do correct
+ * defensive tests of same.
+ *

+/**
+ * @class LLViewerAssetStats
+ * @brief Records performance aspects of asset access operations.
+ *
+ * This facility is derived from a very similar simulator-based
+ * one, LLSimAssetStats.  It's function is to count asset access
+ * operations and characterize response times.  Collected data
+ * are binned in several dimensions:
+ *
+ *  - Asset types collapsed into a few aggregated categories
+ *  - By simulator UUID
+ *  - By transport mechanism (HTTP vs MessageSystem)
+ *  - By persistence (temp vs non-temp)
+ *
+ * Statistics collected are fairly basic at this point:
+ *
+ *  - Counts of enqueue and dequeue operations
+ *  - Min/Max/Mean of asset transfer operations
+ *
+ * This collector differs from the simulator-based on in a
+ * number of ways:
+ *
+ *  - The front-end/back-end distinction doesn't exist in viewer
+ *    code
+ *  - Multiple threads must be safely accomodated in the viewer
+ *
+ * Access to results is by conversion to an LLSD with some standardized
+ * key names.  The intent of this structure is that it be emitted as
+ * standard syslog-based metrics formatting where it can be picked
+ * up by interested parties.
+ *
+ * For convenience, a set of free functions in namespace
+ * LLViewerAssetStatsFF is provided for conditional test-and-call
+ * operations.
