Refactored the following template classes by replacing runtime checks with compile-time checks using if constexpr for improved code clarity and maintainability:
- RID_Alloc
- SortArray
- PagedAllocator
Changes made:
- Updated conditional checks for THREAD_SAFE in the RID_Alloc class.
- Updated conditional checks for Validate in the SortArray class.
- Updated conditional checks for thread_safe in the PagedAllocator class.
PR #90993 added several debugging utilities.
Among them, advanced memory tracking through the use of custom
allocators and VK_EXT_device_memory_report.
However as issue #95967 reveals, it is dangerous to leave it on by
default because drivers (or even the Vulkan loader) can too easily
accidentally break custom allocators by allocating memory through std
malloc but then request us to deallocate it (or viceversa).
This PR fixes the following problems:
- Adds --extra-gpu-memory-tracking cmd line argument
- Adds missing enum entries to
RenderingContextDriverVulkan::VkTrackedObjectType
- Adds RenderingDevice::get_driver_and_device_memory_report
- GDScript users can easily check via print(
RenderingServer.get_rendering_device().get_driver_and_device_memory_report()
)
- Uses get_driver_and_device_memory_report on device lost for appending
further info.
Fixes#95967
InputEventMouseMotion may fire when the mouse hasn't moved.
Also, it generally won't fire when the mouse stops moving.
This makes reliably detecting when the mouse isn't moving tricky.
Update the docs for InputEventMouseMotion to capture these caveats
and give guidance for the best way to detect lack of mouse movement.
InputEventMouseMotion isn't guaranteed to fire only on actual mouse
movement. It's not uncommon for the underlying OS motion event to be
sent either by the OS itself or another application even though the
mouse hasn't moved. Godot will generate such zero-motion
InputEventMouseMotion events itself for things like cursor shape
changes.
Once started, the tooltip timer is reset only after a mouse movement of
at least 5 pixels in one frame.
- Implements the concept of GDExtension loaders that can be used to customize how GDExtensions are loaded and initialized.
- Moves the parsing of `.gdextension` config files to the new `GDExtensionLibraryLoader`.
- `GDExtensionManager` is now meant to be the main way to load/unload extensions and can optionally take a `GDExtensionLoader`.
- `EditorFileSystem` avoids unloading extensions if the file still exists, this should prevent unloading extensions that are outside the user project.
Features:
- Debug-only tracking of objects by type. See
get_driver_allocs_by_object_type et al.
- Debug-only Breadcrumb info for debugging GPU crashes and device lost
- Performance report per frame from get_perf_report
- Some VMA calls had to be modified in order to insert the necessary
memory callbacks
Functionality marked as "debug-only" is only available in debug or dev
builds.
Misc fixes:
- Early break optimization in RenderingDevice::uniform_set_create
============================
The work was performed by collaboration of TheForge and Google. I am
merely splitting it up into smaller PRs and cleaning it up.
