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
* Servers now use WorkerThreadPool for background computation.
* This helps keep the number of threads used fixed at all times.
* It also ensures everything works on HTML5 with threads.
* And makes it easier to support disabling threads for also HTML5.
CommandQueueMT now syncs with the servers via the WorkerThreadPool
yielding mechanism, which makes its classic main sync semaphore
superfluous.
Also, some warnings about calls that kill performance when using
threaded rendering are removed because there's a mechanism that
warns about that in a more general fashion.

* Do not print empty line when header is disabled
* Do not print Vulcan header
* Also add "Print header" project setting (default On)
(suggested by @kaissouDev)
* Add docs for the project setting
(with suggestions by @Mickeon and @akien-mga)

This makes sure that running scenes in debug mode
(from the editor) does not crash Godot.
In export mode it should already work correctly, because
editor-only singletons are never registered in the first place.
Move the benchmarking measuring methods from `Engine` to `OS` to allow for platform specific overrides (e.g: can be used to hook into platform specific benchmarking and tracing capabilities).
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
When using high physics FPS (which is a requirement to minimize input
lag and improve precision in simulation racing games), a higher value
prevents the game from slowing down at low rendering FPS.
This can be done via an Engine property for run-time changes,
or a project setting for initial changes.
This makes the setting easier to find, as research has found there are
numerous use cases to limiting FPS. This also improves documentation
related to the Engine property and project setting.
The project setting also works in projects exported in release mode,
so its location in the `debug/` section was misleading.
This adds support for benchmarking engine startup (and editor startup if used).
The goal is to use this in the benchmarking server to track improvements and changes to engine, editor, importer and scene loading startup times.
This quits the project when an animation is done playing in the
given AnimationPlayer, but only in Movie Maker mode.
When this happens, a message is printed with the absolute path of the
AnimationPlayer node that caused the engine to quit.
This can be used to create videos that stop at a specified time
without having to write any script.
A report is now also printed to the console when the video is done
recording (as long as the engine was exited properly).
This report is unfortunately not always visible in the editor's
Output panel, as it's printed too late.
A method was also added to get the path to the output file from the
scripting API.
* Map is unnecessary and inefficient in almost every case.
* Replaced by the new HashMap.
* Renamed Map to RBMap and Set to RBSet for cases that still make sense
(order matters) but use is discouraged.
There were very few cases where replacing by HashMap was undesired because
keeping the key order was intended.
I tried to keep those (as RBMap) as much as possible, but might have missed
some. Review appreciated!
Split instance and physical device selection function and move device selection to window creation, to reject devices without present capability.
Add device preferred type check in discrete > integrated > virtual > cpu > other order.
Add device list printout.
Add command line argument to override device selection.
* Exposed functions in Engine to register and unregister singletons.
* Added the concept of user singletons, which can be removed (the system ones can't).
This makes it clearer that this property is only about physics FPS,
not rendering FPS.
The `physics_fps` project setting was also renamed to
`physics_ticks_per_second` for consistency.
* Deprecates GDNative in favor of a simpler, lower level interface.
* New extension system allows registering core engine classes.
* Simple header interface in gdnative_interace.h
* Shader compilation is now cached. Subsequent loads take less than a millisecond.
* Improved game, editor and project manager startup time.
* Editor uses .godot/shader_cache to store shaders.
* Game uses user://shader_cache
* Project manager uses $config_dir/shader_cache
* Options to tweak shader caching in project settings.
* Editor path configuration moved from EditorSettings to new class, EditorPaths, so it can be available early on (before shaders are compiled).
* Reworked ShaderCompilerRD to ensure deterministic shader code creation (else shader may change and cache will be invalidated).
* Added shader compression with SMOLV: https://github.com/aras-p/smol-v
This can be used during unit test suite runs to hide error and warning
messages.
Care should be taken when using this feature, as it can hide important
information if used wrongly.
Happy new year to the wonderful Godot community!
2020 has been a tough year for most of us personally, but a good year for
Godot development nonetheless with a huge amount of work done towards Godot
4.0 and great improvements backported to the long-lived 3.2 branch.
We've had close to 400 contributors to engine code this year, authoring near
7,000 commit! (And that's only for the `master` branch and for the engine code,
there's a lot more when counting docs, demos and other first-party repos.)
Here's to a great year 2021 for all Godot users 🎆
