* If the last refcount on a python lambda/temp function is released when a
wrapping std::function is destroyed in a C++ invoke, we can't destroy it
safely. Instead we queue up that decref and process it the next chance we're
able (which is either when the current execution finishes for a python shell
execution, or on the next function call which handles extensions).
* This by no means replaces PySide2, but it allows python extensions to write
simple UIs without needing to rely on PySide2, which might not be available
(generally all windows builds have it as well as recent binary linux builds,
but local windows builds may not and most linux builds probably won't).
* This is a string type which heavily optimises for immutability and minimal
storage. It only contains one pointer to the string data and always
reallocates on modify. For compile-time literals it doesn't modify or
allocate.
* On x64 we use the top bit in a tagged pointer to store a flag of whether it's
heap or literal, on other platforms it uses a separate field (meaning another
pointer sized value effectively, including padding).
* This is best for structured data which tends to use a lot of immutable strings
for type/name information, and only a few for actual string data (which are
only allocated once and aren't modified after that). Similarly we rarely want
to know only the size of any of these strings, we want the whole string so not
explicitly storing the size is not a big deal.
* Overall this reduces SDObject from 128 bytes to 80 bytes.
* When the pyside2 we ship was built it accidentally included a small dependency
on Qt5Qml, which we don't distribute so the pyside2 libraries wouldn't load.
* We can generate a tiny stub with the right exports and load it manually from
the PySide2 folder on 32-bit qrenderdoc builds to allow pyside2 to load
subsequently. The stub source is tiny, and added alongside.
* Putting it in the PySide2 folder means that even if someone puts RenderDoc's
build folder in their PATH, our stub Qt5Qml won't break anything because it
won't be loaded. If they put PySide2 in the PATH it might, but then it's their
fault!
D3D12Pipe now stores an array of root elements, each one corresponding
to a root element or range in the root signature. Migrated usage in the
D3D12 pipeline state viewer and PipeState retrieval of resources.
Restricted number of resource array textures displayed in the texture
viewer to prevent app hangs.
* This allows persistent config storage and registering tweak variables that
works independent of the UI's configuration.
* Config vars can be debug only, which means they will be compiled out in stable
version releases. This allows for debug-logging tweaks that are available in
all builds (including nightly builds) for diagnostic purposes, but have zero
overhead in stable releases.
* Variables have a loose hierarchy defined with _ or . to separate nodes.
* The ShaderDebugTrace now only sets up the initial state of an opaque
ShaderDebugger handle.
* This handle can then be passed to a new function - ContinueDebug - to
iteratively return N more states. The number of states is implementation
defined and may be a fixed number or it may run for a fixed time.
* The states themselves no longer contain a complete snapshot of all variables,
but instead only the changed variables for that iteration. The changes are
stored as before and after value to make it easier to step forwards and
backwards (only the ShaderDebugState is needed to move forward or backwards,
you don't have to search back for the last set value of a variable to 'undo' a
change).
* Moving away from 'registers' explicitly being stored, we now have a single
variable array where the shader representation is responsible for allocating
it.
* In DXBC we calculate the number of each type of mutable variable (temps,
indexable temps, and outputs) and assign slots linearly.
* We also update some naming - high-level variables aren't "locals" since they
could be globals too, and debugging variables aren't "registers" but simply
the variables we use for debugging which may be more complex than float4 for
other APIs.
* The local variable matching by string name is unnecessary for this change
but will be more useful in future after further refactors where there isn't
a single list of variables to index into at the upper level.
* If the UI was launched with a filename as a parameter to open the capture, it
will be added to the recent capture file list. Only later (relatively
speaking) if we make a capture connection will we realise that it is temporary
and potentially delete the file. If we do so, remove the capture from the
recent file list.
* This is only lightly tested and may break heavily. It is disabled by default
and must be explicitly enabled.
* In particular this is only known to work for Wayland use at capture time.
Wayland on replay is still unsupported. Known issues include: EGL pbuffer
surfaces are not implemented on Wayland, Wayland cannot get window dimensions,
and there are hangs/failures with GL and vulkan presentation with Wayland.
* This allows RemoteHost handles to still be valid and usable (if returning
empty data) when they are deleted/removed if the device is disconnected, as
well as providing better multi-thread access (they lock internally)
