Named pipes created using the "pipe://" file access scheme should not be
world-writable or readable. Limit their access to the current user by
creating them with 0600 permissions instead of 0666.
When the "filesystem/on_save/safe_save_on_backup_then_rename" option is
enabled files are created with 0666 permissions (-rw-rw-rw-) which is
too loose. Use 0644 (-rw-r--r--) instead which is how the files would
normally be created with the setting disabled and the system umask taken
into account.
MSAA support is built into GLES3 core, eliminating the need to check for GL_EXT_framebuffer_multisample, which was necessary only in GLES2 due to the lack of inherent multisample framebuffer support. This commit corrects an oversight from GLES2-based code, ensuring compatibility with GLES3 where multisampling is natively supported without extensions.
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
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.
