We've seen hangs/ANR that are not well understood on that spinlock, so
for now we're going back to mutexes, which, on android, are very
efficient under low contention (no syscall).
FIXES=[308029108]
* prevent public classes from being created on the stack
- we used to to this by deleting operator delete, but this prevented
the internal "F" classes from being virtual; which can be useful
when using EntityManger::Listener.
now we just make the destructor protected in each class.
- EntityManger::Listener now has a virtual destructor so that
objects could be correctly destroyed from Listener*
* improve EntityManger and Component managers
- all component managers now have the same "base" API
- getComponentCount()
- empty()
- getEntity()
- getEntities()
- Scene now has getEntityCount()
- EntityManager now has getEntityCount()
- all component manager implement gc() the same way, by calling destroy()
- SingleInstanceComponentManager::gc() that calls removeComponent() has
been removed because it's dangerous. removeComponent() is often
not enough, some additional cleanup might be needed.
CameraManager creates a Transform component for each Camera component
is not already present. However, it didn't destroy the transform
component when it's itself destroyed. the leaked transform component
would eventually be garbage collected, but caused significant
slow down and memory pressure. This is because camera components are
created every frame for the shadow maps.

- the insert and retrieve handlers can now be set/unset independently.
this could be useful for debugging.
- program caching is disabled if the GL implementation doesn't support it.
- removed unused code
FIXES=[307549547]
- Ensure that waiting on lock times out so that we don't lock
up a thread when the client is gone.
- Add an experimental folder to matdbg/web/ for the new
UI work.
The transient property `mRootNotes` in FAssetLoader is built when a new
root asset is created and referenced whenever a new instance is created.
So it incurs an undefined behavior when a previously created asset tries
creating a new instance after a newly created asset has already created
via the same asset loader.
Move this transient property to each asset so that they can reference it
when a new instance is created.
This partially fixes#7269
There's no functional change in this commit.
Make some parameter names more legible by renaming them and put output
parameters to the right of their function.
The temporary variable has been used to store the current instance of
FFilamentAsset being loaded for easy access from internal methods. This
causes a crash as to a complex scenario as follows.
val asset1 = assetLoader.createAsset(assetBuffer1)
val instance1 = assetLoader.createInstance(asset1)
val asset2 = assetLoader.createAsset(assetBuffer2)
val instance2 = assetLoader.createInstance(asset1)
As the first step of fixing this issue, remove the transient property
`mAsset` from FAssetLoader. This commit alone doesn't resolve the issue,
and more commits are following.
Consolidate the low level version of createInstance, which takes a
pointer to cgltf_data type, into the high level version as the latter
one uses a parameter for FFilamentAsset instead of referencing mAsset.
Update all other relevant methods to take a FFilamentAsset pointer
instead of cgltf_data.
This partially fixes#7269
* debugging PCF mode
This mode always uses a hard PCF and takes a
slightly slower code path.
* dynamic shadowmap visualization
The directional shadowmap visualizer is implemented behind a
specialization constant. Add the DebugRegistry infrastructure to be
able to update the spec-constant at runtime and have a subset of
all materials invalidated.
This allows to toggle the visualization at runtime using a debug
property.
This is also a proof of concept that we can update spec-constants
at runtime; we could probably leverage this work for engine-wide
shader configurations.
* Update main.fs
* Update filament/src/details/Material.cpp

- Remove queue submit call when using headless swapchain. It was meant
to emulate a real swapchain, but queue submits are expensive.
- Add option to remove flush and wait when window resizes. If a
headless platform uses this signal to refresh the swapchain, we
don't necessarily need it to also flush and wait before the refresh.
- Refactor VulkanPlatform customizations
- shadows are now stable (in stable mode) when an IBL rotation is
used.
- fix the shadow transform option which didn't work when an IBL rotation
was used
- also use the x-axis as a reference for the "up" direction when
computing the light space matrix so that we don't fall into the
degenerate case when the light points straight down, which is a
common case
FIXES=[299310624]
- Use a hanging-GET approach to reduce dependency on websockets.
- Also add mutex to protect access to MaterialRecords, which is
written to/read from from multiple threads.
