"possible loss of precision" warnings
|

Since timers presents a timers.Timer Lua class supporting queries and
cancellation, make TimersListener::scheduleAfter() and scheduleEvery() respond
immediately so the newly constructed Timer object has the reqid necessary to
perform those subsequent operations.
This requires that Lua invocations of these operations avoid calling the
caller's callback with that initial response.
Reinvent leap.generate() to return a Lua object supporting next() and done()
methods. A plain Lua coroutine that (indirectly) calls fiber.wait() confuses
the fiber scheduler, so avoid implementing generate() as a Lua coroutine.
Add a bit more leap.lua diagnostic output.

The viewer now prefers to load inventory via the capability rather than
over the deprecated Xfer system, though both are still supported.

leap.eventstream() is used when we expect the viewer's LLEventAPI to send an
immediate first response with the reqid from the request, followed by some
number of subsequent responses bearing the same reqid. The difference between
eventstream() and generate() is that generate() expects the caller to request
each such response, whereas eventstream calls the caller's callback with each
response.
cancelreq() is for canceling the background fiber launched by eventstream()
before the callback tells it to quit.
Make WaitFor:close() remove the object from the waitfors list; similarly, make
WaitForReqid:close() remove the object from the pending list. For this reason,
cleanup() must iterate over a copy of each of the pending and waitfors lists.
Instead of unregisterWaitFor() manually searching the waitfors list, use
table.find().

#1597 Fix for some GLTF transforms not loading properly.
|
|
|
|
Also incidental fix for unreachable code error.
|

Turn on LL_TESTS for Maint B.
|
|
Attempt to diagnose stack overflow in test programs. Also, improve build.yaml logic.
|
|
Having done that, fall back to default `continue-on-error: false` for all
platforms.

* Migrate GLTF scene rendering to its own shaders
* Add support for ambient occlusion map separate from metallic roughness map (or absent)
* Use UBO's for GLTF joints
* Better error handling of downloading GLTF assets

Start trimming trailing whitespace, but limit the blast radius to a
handful of file types.

Otherwise we fall into the trap of destroying a joinable std::thread, which
calls std::terminate() and hence our crash-on-terminate() handler.
The previous ~ThreadPool() logic only joined threads if the queue wasn't
already closed, but evidently we can reach the destructor with the queue
closed but the threads not yet joined.
Fixes #1534.

Introduce AlwaysReturn<void> specialization, which always discards any result
of calling the specified callable with specified args.
Derive new Windows_SEH_exception from LLException, not std::runtime_error.
Put the various SEH functions in LL::seh nested namespace, e.g.
LL::seh::catcher() as the primary API.
Break out more levels of Windows SEH handler to work around the restrictions on
functions containing __try/__except.
The triadic catcher() overload now does little save declare a std::string
stacktrace before forwarding the call to catcher_inner(), passing a reference
to stacktrace along with the trycode, filter and handler functions.
catcher_inner() accepts the stacktrace and the three function template
arguments. It contains the __try/__except logic. It calls a new filter_()
wrapper template, which calls fill_stacktrace() before forwarding the call to
the caller's filter function. fill_stacktrace(), in the .cpp file, contains
the logic to populate the stacktrace string -- unless the Structured Exception
is stack overflow, in which case it puts an explanatory string instead.
catcher_inner()'s __except clause passes not only the code, but also the
stacktrace string, to the caller's handler function. It wraps the caller's
handler function in always_return<rtype>(), where rtype is the type returned
by the trycode function. This allows a handler to return a value, while also
supporting the void handler case, e.g. one that throws a C++ exception. (This
is why we need AlwaysReturn<void>: some trycode() functions are themselves
void.)
For the dyadic catcher() overload, introduce common_filter() containing the
logic to distinguish a C++ exception from any other kind of Structured
Exception. The fact that the stacktrace is captured before the filter function
is called should permit capturing a stacktrace for a C++ exception as well as
for most other Structured Exceptions.
As before, the monadic catcher() overload supplies the rethrow() handler, in
the .cpp file.
Change existing calls from seh_catcher() to LL::seh::catcher().
