`LLEventAPI` is specifically intended to allow a LEAP plugin, or a Lua script,
to access certain viewer functionality. Errors in external code like that
cannot be addressed during viewer development. Any code path that allows
external code in any form to crash the viewer opens up a potential abuse
vector, if a trusting user runs external code from an untrustworthy source.
`LLDispatchListener` reports exceptions back to its invoker, if the invoker
provides a "reply" `LLEventPump` name. Absent "reply", though,
`LLDispatchListener` is documented to let any such exception propagate. That
behavior may be okay for internal use, but in the case of the `LLEventAPI`
subclass, it veers into the abuse scenario described above.
Make `LLEventAPI` ensure that any exception propagating from `LLDispatchListener`
is caught and logged, but not propagated.
Also enrich error reporting for the "batch" `LLDispatchListener` operations.

Remove documented `LLEventPump` support for `LLEventTrackable`. That claimed
support was always a little bit magical/fragile. IF:
* a class included `LLEventTrackable` as a base class AND
* an instance of that class was managed by `boost::shared_ptr` AND
* you passed one of that class's methods and the `boost::shared_ptr`
specifically to `boost::bind()` AND
* the resulting `boost::bind()` object was passed into `LLEventPump::listen()`
THEN the promise was that on destruction of that object, that listener would
automatically be disconnected -- instead of leaving a dangling pointer bound
into the `LLEventPump`, causing a crash on the next `LLEventPump::post()` call.
The only existing code in the viewer code base that exercised `LLEventTrackable`
functionality was in test programs. When the viewer calls `LLEventPump::listen()`,
it typically stores the resulting connection object in an `LLTempBoundListener`
variable, which guarantees disconnection on destruction of that variable.
The fact that `LLEventTrackable` support is specific to `boost::bind()`, that it
silently fails to keep its promise with `std::bind()` or a lambda or any other
form of C++ callable, makes it untrustworthy for new code.
Note that the code base still uses `boost::signals2::trackable` for other
`boost::signals2::signal` instances not associated with `LLEventPump`. We are
not changing those at this time.

`listen()` still takes `LLEventListener`, a `callable(const LLSD&)`, but now
also accepts `LLAwareListener`, a `callable(const LLBoundListener&, const LLSD&)`.
This uses `boost::signals2::signal::connect_extended()`, which, when the
signal is called, passes to a connected listener the `LLBoundListener` (aka
`boost::signals2::connection`) representing its own connection. This allows a
listener to disconnect itself when done.
Internally, `listen_impl()` now always uses `connect_extended()`. When passed
a classic `LLEventListener`, `listen()` wraps it in a lambda that ignores the
passed `LLBoundListener`.
`listen()` also now accepts `LLVoidListener`, and internally wraps it in a lambda
that returns `false` on its behalf.

* Fix: Update calcDataSizeJ2C to pyramid-base file size estimation
Used the loop from the previous LayerFactored method to create a more accurate file size estimation by walking up the pyramid tiles.
Sizes are much larger in many cases and eliminate partial decoder issues with OpenJPEG.
KDU not tested but expected to produce better files as well.
Should also stop decode failures on tiny or very rectangular dimensions.

gcc complains about this iterator not being const
|

gcc detects usage of this array as uninitialized, so make sure it's initialized. I am not sure if this is a legitimate warning, or if the code guarantees the array gets initialized before use in lines 140-142 and this is a performance optimization.

secondlife/viewer#1885: Terrain texture repeats: Remove feature flag dependency on simulator feature in favor of cap
|

We couldn't discard the "p.s." fiber.run() call from LuaState::expr() until we
could count on fiber.lua's LL.atexit(fiber.run) call being executed after each
Lua script or chunk, and we couldn't count on that until we made
LLLUAmanager::runScriptFile() instantiate and destroy its LuaState on the C++
Lua-specific coroutine. Now that we've done that, use LL.atexit(fiber.run)
instead of the whole special-case "p.s." in LuaState::expr().
|
|
Remove LLLUAmanager::mumbleScriptLine() LuaState& parameters. Make
startScriptLine(), waitScriptLine() and runScriptLine() exactly parallel to
startScriptFile(), waitScriptFile() and runScriptFile(). That means that
runScriptLine()'s C++ coroutine instantiates and destroys its own LuaState,
which means that LL.atexit() functions will run on the Lua-specific C++
coroutine rather than (say) the viewer's main coroutine.
Introduce LLLUAmanager::script_result typedef for std::pair<int, LLSD> and use
in method returns.
Remove LuaState::initLuaState(); move its logic back into the constructor.
Remove initLuaState() calls in the expr() error cases: they're moot now that
we won't get subsequent expr() calls on the same LuaState instance.
Remove LLFloaterLUADebug "Use clean lua_State" checkbox and the cleanLuaState()
method. Remove mState member.
Remove explicit LuaState declarations from LLLUAmanager tests. Adapt one test
for implicit LuaState: it was directly calling LuaState::obtainListener() to
discover the LuaListener's reply-pump name. But since that test also captures
two leap.request() calls from the Lua script, it can just look at the "reply"
key in either of those requests.
