+/// @file lldeadmantimer.h
+///
+/// There are interesting user-experienced events in the viewer that
+/// would seem to have well-defined start and stop points but which
+/// actually lack such milestones in the code. Such events (like
+/// time to load meshes after logging in, initial inventory load,
+/// display name fetch) can be defined somewhat after-the-fact by
+/// noticing when we no longer perform operations towards their
+/// completion. This class is intended to help in such applications.
+///
+/// What it implements is a deadman's switch (also known as a
+/// keepalive switch and a doorbell switch). The basic operation is
+/// as follows:
+///
+/// * LLDeadmanTimer is instantiated with a horizon value in seconds,
+/// one for each event of interest.
+/// * When an event starts, @see start() is invoked to begin a
+/// timing operation.
+/// * As operations are performed in service of the event (issuing
+/// HTTP requests, receiving responses), @see ringBell() is invoked
+/// to inform the timer that the operation is still active.
+/// * If the operation is canceled or otherwise terminated, @see
+/// stop() can be called to end the timing operation.
+/// * Concurrent with the ringBell() calls, the program makes
+/// periodic (shorter than the horizon but not too short) calls
+/// to @see isExpired() to see if the event has expired due to
+/// either a stop() call or lack of activity (defined as a ringBell()
+/// call in the previous 'horizon' seconds). If it has expired,
+/// the caller also receives start, stop and count values for the
+/// event which the application can then report in whatever manner
+/// it sees fit.
+/// * The timer becomes passive after an isExpired() call that returns
+/// true. It can then be restarted with a new start() call.
+///
+/// Threading: Instances are not thread-safe. They also use
+/// timing code from lltimer.h which is also unsafe.
+///
+/// Allocation: Not refcounted, may be stack or heap allocated.
+///

+
+
+1. HTTP Fetching in 15 Minutes
+
+ Let's start with a trivial working example. You'll need a throwaway
+ build of the viewer. And we'll use indra/newview/llappviewer.cpp as
+ the host module for these hacks.
+
+ First, add some headers:
+
+
+ #include "httpcommon.h"
+ #include "httprequest.h"
+ #include "httphandler.h"
+
+
+ You'll need to derive a class from HttpHandler (not HttpHandle).
+ This is used to deliver notifications of HTTP completion to your
+ code. Place it near the top, before LLDeferredTaskList, say:
+
+
+ class MyHandler : public LLCore::HttpHandler
+ {
+ public:
+ MyHandler()
+ : LLCore::HttpHandler()
+ {}
+
+ virtual void onCompleted(LLCore::HttpHandle /* handle */,
+ LLCore::HttpResponse * /* response */)
+ {
+ LL_INFOS("Hack") << "It is happening again." << LL_ENDL;
+
+ delete this; // Last statement
+ }
+ };
+
+
+ Add some statics up there as well:
+
+
+ // Our request object. Allocate during initialiation.
+ static LLCore::HttpRequest * my_request(NULL);
+
+ // The policy class for HTTP traffic.
+ // Use HttpRequest::DEFAULT_POLICY_ID, but DO NOT SHIP WITH THIS VALUE!!
+ static LLCore::HttpRequest::policy_t my_policy(LLCore::HttpRequest::DEFAULT_POLICY_ID);
+
+ // Priority for HTTP requests. Use 0U.
+ static LLCore::HttpRequest::priority_t my_priority(0U);
+
+
+ In LLAppViewer::init() after mAppCoreHttp.init(), create a request object:
+
+
+ my_request = new LLCore::HttpRequest();
+
+
+ In LLAppViewer::mainLoop(), just before entering the while loop,
+ we'll kick off one HTTP request:
+
+
+ // Construct a handler object (we'll use the heap this time):
+ MyHandler * my_handler = new MyHandler;
+
+ // Issue a GET request to 'http://www.example.com/' kicking off
+ // all the I/O, retry logic, etc.
+ LLCore::HttpHandle handle;
+ handle = my_request->requestGet(my_policy,
+ my_priority,
+ "http://www.example.com/",
+ NULL,
+ NULL,
+ my_handler);
+ if (LLCORE_HTTP_HANDLE_INVALID == handle)
+ {
+ LL_WARNS("Hack") << "Failed to launch HTTP request. Try again."
+ << LL_ENDL;
+ }
+
+
+ Finally, arrange to periodically call update() on the request object
+ to find out when the request completes. This will be done by
+ calling the onCompleted() method with status information and
+ response data from the HTTP operation. Add this to the
+ LLAppViewer::idle() method after the ping:
+
+
+ my_request->update(0);
+
+
+ That's it. Build it, run it and watch the log file. You should get
+ the "It is happening again." message indicating that the HTTP
+ operation completed in some manner.
+
+
+2. What Does All That Mean
+
+ MyHandler/HttpHandler. This class replaces the Responder-style in
+ legacy code. One method is currently defined. It is used for all
+ request completions, successful or failed:
+
+
+ void onCompleted(LLCore::HttpHandle /* handle */,
+ LLCore::HttpResponse * /* response */);
+
+
+ The onCompleted() method is invoked as a callback during calls to
+ HttpRequest::update(). All I/O is completed asynchronously in
+ another thread. But notifications are polled by calling update()
+ and invoking a handler for completed requests.
+
+ In this example, the invocation also deletes the handler (which is
+ never referenced by the llcorehttp code again). But other
+ allocation models are possible including handlers shared by many
+ requests, stack-based handlers and handlers mixed in with other,
+ unrelated classes.
+
+ LLCore::HttpRequest(). Instances of this class are used to request
+ all major functions of the library. Initialization, starting
+ requests, delivering final notification of completion and various
+ utility operations are all done via instances. There is one very
+ important rule for instances:
+
+ Request objects may NOT be shared between threads.
+
+ my_priority. The APIs support the idea of priority ordering of
+ requests but it hasn't been implemented and the hope is that this
+ will become useless and removed from the interface. Use 0U except
+ as noted.
+
+ my_policy. This is an important one. This library attempts to
+ manage TCP connection usage more rigorously than in the past. This
+ is done by issuing requests to a queue that has various settable
+ properties. These establish connection usage for the queue as well
+ as how queues compete with one another. (This is patterned after
+ class-based queueing used in various networking stacks.) Several
+ classes are pre-defined. Deciding when to use an existing class and
+ when to create a new one will determine what kind of experience
+ users have. We'll pick up this question in detail below.
+
+ requestGet(). Issues an ordinary HTTP GET request to a given URL
+ and associating the request with a policy class, a priority and an
+ response handler. Two additional arguments, not used here, allow
+ for additional headers on the request and for per-request options.
+ If successful, the call returns a handle whose value is other than
+ LLCORE_HTTP_HANDLE_INVALID. The HTTP operation is then performed
+ asynchronously by another thread without any additional work by the
+ caller. If the handle returned is invalid, you can get the status
+ code by calling my_request->getStatus().
+
+ update(). To get notification that the request has completed, a
+ call to update() will invoke onCompleted() methods.
+
+

+ MyHandler::onCompleted(). You'll want to do something useful with
+ your response. Distinguish errors from successes and getting the
+ response body back in some form.
+
+ Add a new header:
+
+
+ #include "bufferarray.h"
+
+
+ Replace the existing MyHandler::onCompleted() definition with:
+
+
+ virtual void onCompleted(LLCore::HttpHandle /* handle */,
+ LLCore::HttpResponse * response)
+ {
+ LLCore::HttpStatus status = response->getStatus();
+ if (status)
+ {
+ // Successful request. Try to fetch the data
+ LLCore::BufferArray * data = response->getBody();
+
+ if (data && data->size())
+ {
+ // There's some data. A BufferArray is a linked list
+ // of buckets. We'll create a linear buffer and copy
+ // the data into it.
+ size_t data_len = data->size();
+ char * data_blob = new char [data_len + 1];
+ data->read(0, data_blob, data_len);
+ data_blob[data_len] = '\0';
+
+ // Process the data now in NUL-terminated string.
+ // Needs more scrubbing but this will do.
+ LL_INFOS("Hack") << "Received: " << data_blob << LL_ENDL;
+
+ // Free the temporary data
+ delete [] data_blob;
+ }
+ }
+ else
+ {
+ // Something went wrong. Translate the status to
+ // a meaningful message.
+ LL_WARNS("Hack") << "HTTP GET failed. Status: "
+ << status.toTerseString()
+ << ", Reason: " << status.toString()
+ << LL_ENDL;
+ }
+
+ delete this; // Last statement
+ }
+
+
+ HttpHeaders. The header file "httprequest.h" documents the expected
+ important headers that will go out with the request. You can add to
+ these by including an HttpHeaders object with the requestGet() call.
+ These are typically setup once as part of init rather than
+ dynamically created.
+
+ Add another header:
+
+
+ #include "httpheaders.h"
+
+
+ In LLAppViewer::mainLoop(), add this alongside the allocation of
+ my_handler:
+
+
+ // Additional headers for all requests
+ LLCore::HttpHeaders * my_headers = new LLCore::HttpHeaders();
+ my_headers->append("Accept", "text/html, application/llsd+xml");
+
+
+ HttpOptions. Options are similar and include a mix of value types.
+ One interesting per-request option is the trace setting. This
+ enables various debug-type messages in the log file that show the
+ progress of the request through the library. It takes values from
+ zero to three with higher values giving more verbose logging. We'll
+ use '2' and this will also give us a chance to verify that
+ HttpHeaders works as expected.
+
+ Same as above, a new header:
+
+
+ #include "httpoptions.h"
+
+
+ And in LLAppView::mainLoop():
+
+
+ // Special options for requests
+ LLCore::HttpOptions * my_options = new LLCore::HttpOptions();
+ my_options->setTrace(2);
+
+
+ Now let's put that all together into a more complete requesting
+ sequence. Replace the existing invocation of requestGet() with this
+ slightly more elaborate block:
+
+
+ LLCore::HttpHandle handle;
+ handle = my_request->requestGet(my_policy,
+ my_priority,
+ "http://www.example.com/",
+ my_options,
+ my_headers,
+ my_handler);
+ if (LLCORE_HTTP_HANDLE_INVALID == handle)
+ {
+ LLCore::HttpStatus status = my_request->getStatus();
+
+ LL_WARNS("Hack") << "Failed to request HTTP GET. Status: "
+ << status.toTerseString()
+ << ", Reason: " << status.toString()
+ << LL_ENDL;
+
+ delete my_handler; // No longer needed.
+ my_handler = NULL;
+ }
+
+
+ Build, run and examine the log file. You'll get some new data with
+ this run. First, you should get the www.example.com home page

+
+
+4. What Does All That Mean, Part 2
+
+ HttpStatus. The HttpStatus object encodes errors from libcurl, the
+ library itself and HTTP status values. It does this to avoid
+ collapsing all non-HTTP error into a single '499' HTTP status and to
+ make errors distinct.
+
+ To aid programming, the usual bool conversions are available so that
+ you can write 'if (status)' and the expected thing will happen
+ whether it's an HTTP, libcurl or library error. There's also
+ provision to override the treatment of HTTP errors (making 404 a
+ success, say).
+
+ Share data, don't copy it. The library was started with the goal of
+ avoiding data copies as much as possible. Instead, read-only data
+ sharing across threads with atomic reference counts is used for a
+ number of data types. These currently are:
+
+ * BufferArray. Linked list of data blocks/HTTP bodies.
+ * HttpHeaders. Shared headers for both requests and responses.
+ * HttpOptions. Request-only data modifying HTTP behavior.
+ * HttpResponse. HTTP response description given to onCompleted.
+
+ Using objects of these types requires a few rules:
+
+ * Constructor always gives a reference to caller.
+ * References are dropped with release() not delete.
+ * Additional references may be taken out with addRef().
+ * Unless otherwise stated, once an object is shared with another
+ thread it should be treated as read-only. There's no
+ synchronization on the objects themselves.
+
+ HttpResponse. You'll encounter this mainly in onCompleted() methods.
+ Commonly-used interfaces on this object:
+
+ * getStatus() to return the final status of the request.
+ * getBody() to retrieve the response body which may be NULL or
+ zero-length.
+ * getContentType() to return the value of the 'Content-Type'
+ header or an empty string if none was sent.
+
+ This is a reference-counted object so you can call addRef() on it
+ and hold onto the response for an arbitrary time. But you'll
+ usually just call a few methods and return from onCompleted() whose
+ caller will release the object.
+
+ BufferArray. The core data representation for request and response
+ bodies. In HTTP responses, it's fetched with the getBody() method
+ and may be NULL or non-NULL with zero length. All successful data
+ handling should check both conditions before attempting to fetch
+ data from the object. Data access model uses simple read/write
+ semantics:
+
+ * append()
+ * size()
+ * read()
+ * write()
+
+ (There is a more sophisticated stream adapter that extends these
+ methods and will be covered below.) So, one way to retrieve data
+ from a request is as follows:
+
+
+ LLCore::BufferArray * data = response->getBody();
+ if (data && data->size())
+ {
+ size_t data_len = data->size();
+ char * data_blob = new char [data_len + 1];
+ data->read(0, data_blob, data_len);
+
+
+ HttpOptions and HttpResponse. Really just simple containers of POD
+ and std::string pairs. But reference counted and the rule about not
+ modifying after sharing must be followed. You'll have the urge to
+ change options dynamically at some point. And you'll try to do that
+ by just writing new values to the shared object. And in tests
+ everything will appear to work. Then you ship and people in the
+ real world start hitting read/write races in strings and then crash.
+ Don't be lazy.
+
+ HttpHandle. Uniquely identifies a request and can be used to
+ identify it in an onCompleted() method or cancel it if it's still
+ queued. But as soon as a request's onCompleted() invocation
+ returns, the handle becomes invalid and may be reused immediately
+ for new requests. Don't hold on to handles after notification.
+
+
+5. And Still More Refinements
+
+ (Note: The following refinements are just code fragments. They
+ don't directly fit into the working example above. But they
+ demonstrate several idioms you'll want to copy.)
+
+ LLSD, std::streambuf, std::iostream. The read(), write() and
+ append() methods may be adequate for your purposes. But we use a
+ lot of LLSD. Its interfaces aren't particularly compatible with
+ BufferArray. And so two adapters are available to give
+ stream-like behaviors: BufferArrayStreamBuf and BufferArrayStream,
+ which implement the std::streambuf and std::iostream interfaces,
+ respectively.
+
+ A std::streambuf interface isn't something you'll want to use
+ directly. Instead, you'll use the much friendlier std::iostream
+ interface found in BufferArrayStream. This adapter gives you all
+ the '>>' and '<<' operators you'll want as well as working
+ directly with the LLSD conversion operators.
+
+ Some new headers:
+
+
+ #include "bufferstream.h"
+ #include "llsdserialize.h"
+
+
+ And an updated fragment based on onCompleted() above:
+
+
+ // Successful request. Try to fetch the data
+ LLCore::BufferArray * data = response->getBody();
+ LLSD resp_llsd;
+
+ if (data && data->size())
+ {
+ // There's some data and we expect this to be
+ // LLSD. Checking of content type and validation
+ // during parsing would be admirable additions.
+ // But we'll forgo that now.
+ LLCore::BufferArrayStream data_stream(data);
+ LLSDSerialize::fromXML(resp_llsd, data_stream);
+ }
+ LL_INFOS("Hack") << "LLSD Received: " << resp_llsd << LL_ENDL;
+ }
+ else
+ {
+
+
+ Converting an LLSD object into an XML stream stored in a
+ BufferArray is just the reverse of the above:
+
+
+ BufferArray * data = new BufferArray();
+ LLCore::BufferArrayStream data_stream(data);
+
+ LLSD src_llsd;
+ src_llsd["foo"] = "bar";
+
+ LLSDSerialize::toXML(src_llsd, data_stream);
+
+ // 'data' now contains an XML payload and can be sent
+ // to a web service using the requestPut() or requestPost()
+ // methods.
+ ... requestPost(...);
+
+ // And don't forget to release the BufferArray.
+ data->release();
+ data = NULL;
+
+
+ LLSD will often go hand-in-hand with BufferArray and data
+ transport. But you can also do all the streaming I/O you'd expect
+ of a std::iostream object:
+
+
+ BufferArray * data = new BufferArray();
+ LLCore::BufferArrayStream data_stream(data);
+
+ data_stream << "Hello, World!" << 29.4 << '\n';
+ std::string str;
+ data_stream >> str;
+ std::cout << str << std::endl;
+
+ data->release();
+ // Actual delete will occur when 'data_stream'
+ // falls out of scope and is destructed.
+
+
+ Scoping objects and cleaning up. The examples haven't bothered
+ with cleanup of objects that are no longer needed. Instead, most
+ objects have been allocated as if they were global and eternal.
+ You'll put the objects in more appropriate feature objects and
+ clean them up as a group. Here's a checklist for actions you may
+ need to take on cleanup:
+
+ * Call delete on:
+ o HttpHandlers created on the heap
+ o HttpRequest objects
+ * Call release() on:
+ o BufferArray objects
+ o HttpHeaders objects
+ o HttpOptions objects
+ o HttpResponse objects
+
+ On program exit, as threads wind down, the library continues to
+ operate safely. Threads don't interact via the library and even
+ dangling references to HttpHandler objects are safe. If you don't
+ call HttpRequest::update(), handler references are never
+ dereferenced.
+
+ You can take a more thorough approach to wind-down. Keep a list
+ of HttpHandles (not HttpHandlers) of outstanding requests. For
+ each of these, call HttpRequest::requestCancel() to cancel the
+ operation. (Don't add the cancel requests' handled to the list.)
+ This will cancel the outstanding requests that haven't completed.
+ Canceled or completed, all requests will queue notifications. You
+ can now cycle calling update() discarding responses. Continue
+ until all requests notify or a few seconds have passed.
+
+ Global startup and shutdown is handled in the viewer. But you can
+ learn about it in the code or in the documentation in the headers.
+
+
+6. Choosing a Policy Class
+
+ Now it's time to get rid of the default policy class. Take a look
+ at the policy class definitions in newview/llappcorehttp.h.
+ Ideally, you'll find one that's compatible with what you're doing.
+ Some of the compatibility guidelines are:
+
+ * Destination: Pair of host and port. Mixing requests with
+ different destinations may cause more connection setup and tear
+ down.
+
+ * Method: http or https. Usually moot given destination. But
+ mixing these may also cause connection churn.
+
+ * Transfer size: If you're moving 100MB at a time and you make your
+ requests to the same policy class as a lot of small, fast event
+ information that fast traffic is going to get stuck behind you
+ and someone's experience is going to be miserable.
+
+ * Long poll requests: These are long-lived, must- do operations.
+ They have a special home called AP_LONG_POLL.
+
+ * Concurrency: High concurrency (5 or more) and large transfer
+ sizes are incompatible. Another head-of-the-line problem. High
+ concurrency is tolerated when it's desired to get maximal
+ throughput. Mesh and texture downloads, for example.
+
+ * Pipelined: If your requests are not idempotent, stay away from
+ anything marked 'soon' or 'yes'. Hidden retries may be a
+ problem for you. For now, would also recommend keeping PUT and
+ POST requests out of classes that may be pipelined. Support for
+ that is still a bit new.
+
+ If you haven't found a compatible match, you can either create a
+ new class (llappcorehttp.*) or just use AP_DEFAULT, the catchall
+ class when all else fails. Inventory query operations might be a
+ candidate for a new class that supported pipelining on https:.
+ Same with display name lookups and other bursty-at-login
+ operations. For other things, AP_DEFAULT will do what it can and
+ will, in some way or another, tolerate any usage. Whether the
+ users' experiences are good are for you to determine.
+
+
+7. FAQ
+
+ Q1. What do these policy classes achieve?
+
+ A1. Previously, HTTP-using code in the viewer was written as if
+ it were some isolated, local operation that didn't have to
+ consider resources, contention or impact on services and the
+ larger environment. The result was an application with on the
+ order of 100 HTTP launch points in its codebase that could create
+ dozens or even 100's of TCP connections zeroing in on grid
+ services and disrupting networking equipment, web services and
+ innocent users. The use of policy classes (modeled on
+ http://en.wikipedia.org/wiki/Class-based_queueing) is a means to
+ restrict connection concurrency, good and necessary in itself. In
+ turn, that reduces demands on an expensive resource (connection
+ setup and concurrency) which relieves strain on network points.
+ That enables connection keepalive and opportunites for true
+ improvements in throughput and user experience.
+
+ Another aspect of the classes is that they give some control over
+ how competing demands for the network will be apportioned. If
+ mesh fetches, texture fetches and inventory queries are all being
+ made at once, the relative weights of their classes' concurrency
+ limits established that apportioning. We now have an opportunity
+ to balance the entire viewer system.
+
+ Q2. How's that data sharing with refcounts working for you?
+
+ A2. Meh. It does reduce memory churn and the frequency at which
+ free blocks must be moved between threads. But it's also a design
+ for static configuration and dynamic reconfiguration (not
+ requiring a restart) is favored. Creating new options for every
+ request isn't too bad, it a sequence of "new, fill, request,
+ release" for each requested operation. That in contrast to doing
+ the "new, fill, release" at startup. The bad comes in getting at
+ the source data. One rule in this work was "no new thread
+ problems." And one source for those is pulling setting values out
+ of gSettings in threads. None of that is thread safe though we
+ tend to get away with it.
+
+ Q3. What needs to be done?
+
+ A3. There's a To-Do list in _httpinternal.h. It has both large
+ and small projects here if someone would like to try changes.

+// 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

+// 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.

+// 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.
