+// Purpose
+//
+// The purpose of this module is to provide access between the viewer
+// and the asset system as regards to mesh objects.
+//
+// * High-throughput download of mesh assets from servers while
+// following best industry practices for network profile.
+// * Reliable expensing and upload of new mesh assets.
+// * Recovery and retry from errors when appropriate.
+// * Decomposition of mesh assets for preview and uploads.
+// * And most important: all of the above without exposing the
+// main thread to stalls due to deep processing or thread
+// locking actions. In particular, the following operations
+// on LLMeshRepository are very averse to any stalls:
+// * loadMesh
+// * getMeshHeader (For structural details, see:
+// http://wiki.secondlife.com/wiki/Mesh/Mesh_Asset_Format)
+// * notifyLoadedMeshes
+// * getSkinInfo
+//
+// Threads
+//
+// main Main rendering thread, very sensitive to locking and other stalls
+// repo Overseeing worker thread associated with the LLMeshRepoThread class
+// decom Worker thread for mesh decomposition requests
+// core HTTP worker thread: does the work but doesn't intrude here
+// uploadN 0-N temporary mesh upload threads (0-1 in practice)
+//
+// Sequence of Operations
+//
+// What follows is a description of the retrieval of one LOD for
+// a new mesh object. Work is performed by a series of short, quick
+// actions distributed over a number of threads. Each is meant
+// to proceed without stalling and the whole forms a deep request
+// pipeline to achieve throughput. Ellipsis indicates a return
+// or break in processing which is resumed elsewhere.
+//
+// main thread repo thread (run() method)
+//
+// loadMesh() invoked to request LOD
+// append LODRequest to mPendingRequests

+// LLPhysicsDecomp::mMutex
+// LLMeshUploadThread::mMutex
+//
+// Mutex Order Rules
+//
+// 1. LLMeshRepoThread::mMutex before LLMeshRepoThread::mHeaderMutex
+// 2. LLMeshRepository::mMeshMutex before LLMeshRepoThread::mMutex
+// (There are more rules, haven't been extracted.)
+//
+// Data Member Access/Locking
+//
+// Description of how shared access to static and instance data
+// members is performed. Each member is followed by the name of
+// the mutex, if any, covering the data and then a list of data
+// access models each of which is a triplet of the following form:
+//
+// {ro, wo, rw}.{main, repo, any}.{mutex, none}
+// Type of access: read-only, write-only, read-write.
+// Accessing thread or 'any'
+// Relevant mutex held during access (several may be held) or 'none'
+//
+// A careful eye will notice some unsafe operations. Many of these
+// have an alibi of some form. Several types of alibi are identified
+// and listed here:
+//
+// [0] No alibi. Probably unsafe.
+// [1] Single-writer, self-consistent readers. Old data must
+// be tolerated by any reader but data will come true eventually.
+// [2] Like [1] but provides a hint about thread state. These
+// may be unsafe.
+// [3] empty() check outside of lock. Can me made safish when
+// done in double-check lock style. But this depends on
+// std:: implementation and memory model.
+// [4] Appears to be covered by a mutex but doesn't need one.
+// [5] Read of a double-checked lock.
+//
+// So, in addition to documentation, take this as a to-do/review
+// list and see if you can improve things. For porters to non-x86
+// architectures, the weaker memory models will make these platforms
+// probabilistically more susceptible to hitting race conditions.
+// True here and in other multi-thread code such as texture fetching.
+// (Strong memory models make weak programmers. Weak memory models
+// make strong programmers. Ref: arm, ppc, mips, alpha)

+// Debug variable 'MeshUploadFakeErrors' takes a mask of bits that will
+// simulate an error on fee query or upload. Defined bits are:
+//
+// 0x01 Simulate application error on fee check reading
+// response body from file "fake_upload_error.xml"
+// 0x02 Same as 0x01 but for actual upload attempt.
+// 0x04 Simulate a transport problem on fee check with a
+// locally-generated 500 status.
+// 0x08 As with 0x04 but for the upload operation.
+//
+// For major changes, see the LL_MESH_FASTTIMER_ENABLE below and
+// instructions for looking for frame stalls using fast timers.
+//
+// *TODO: Work list for followup actions:
+// * Review anything marked as unsafe above, verify if there are real issues.
+// * See if we can put ::run() into a hard sleep. May not actually perform better
+// than the current scheme so be prepared for disappointment. You'll likely
+// need to introduce a condition variable class that references a mutex in
+// methods rather than derives from mutex which isn't correct.
+// * On upload failures, make more information available to the alerting
+// dialog. Get the structured information going into the log into a
+// tree there.
+// * Header parse failures come without much explanation. Elaborate.
+// * Work queue for uploads? Any need for this or is the current scheme good
+// enough?
+// * Various temp buffers used in VFS I/O might be allocated once or even
+// statically. Look for some wins here.
+// * Move data structures holding mesh data used by main thread into main-
+// thread-only access so that no locking is needed. May require duplication
+// of some data so that worker thread has a minimal data set to guide
+// operations.
