Since char/wchar_t can be either signed or unsigned, its conversion to uint32_t leads to different values depending on platform.
In particular, the same string represented as char* (Latin-1; StringName direct construction) or uint32_t (UTF-8; constructed
via String) previously resulted in different hashes.
So far, an indirection via String was necessary, causing at least 2 allocations and copies (String; String inside StringName).
Since StringNames often refer to string literals, this allows them to be directly constructed from C strings.
There are two formats: Latin-1 and UTF-8.
The Latin-1 constructor also provides the `p_is_static` flag: when the source has static storage duration, no copy/allocation will be needed.
However, the extension developer needs to uphold this lifetime guarantee.
Removes a line from Projection::get_z_far that flips the normal of a plane.
While this may be required for similar code elsewhere in the file, this is
unnecessary here, as only the length of the normal is used and not the
direction. Flipping the normal does not change its magnitude and therefore is
unnecessary in this case.
This adds two functions to `GDExtensionClassCreationInfo` that allow for developers to supply a generic virtual call function along with user data to be sent to that call.
If `get_virutal_call_data_func` is not null, extensions call this function to get user data to pass to a supplied `call_virtual_with_data_func`. Both must be provided is one is provided.
If `get_virtual_call_data_func` is null, Godot falls back to the old `get_virtual_func` logic.

Fixes#79036. sign(NAN) now returns 0.
This should not impact performance much in any way.
Adds a test for the NAN case. Updates the documentation to clarify the new behavior.
The UWP platform port was never ported to the Godot 4.0+ API,
and it's now accumulating bitrot as it doesn't compile, and thus
we no longer propagate platform changes in it.
So we finally remove to acknowledge this state. There's still some
interest in reviving the UWP port eventually, especially as support
for Direct3D 12 will soon be merged, but when that happens it will
be easiest to redo it from scratch.
This allows to include script_instance.h directly in the
generated gdvirtual.gen.inc, and remove excessive includes
from the codebase.
This should also allow Resource to use GDVIRTUAL macros,
which wasn't possible previously due to a circular dependency.
PCK files (like other build products) should be deterministic based on their inputs. Removed calls to Math::rand() that are being used to generate padding.
Looks like these were introduced as part of adding encryption support, but the padding being random does not have any cryptographic significance. This can be trivially inferred since file blocks that happen to be aligned don't get padding anyway.
If there's a desire to indroduce something that functions as a nonce it should probably be added explicitly and only if encryption is enabled.
remove Math::rand() calls in editor_export_platform.cpp
follow up to make consistent with pck_packer
GDScript has the following built-in trigonometry functions:
- `sin()`
- `cos()`
- `tan()`
- `asin()`
- `acos()`
- `atan()`
- `atan()`
- `sinh()`
- `cosh()`
- `tanh()`
However, it lacks the hyperbolic arc (also known as inverse
hyperbolic) functions:
- `asinh()`
- `acosh()`
- `atanh()`
Implement them by just exposing the C++ Math library, but clamping
its values to the closest real defined value.
For the cosine, clamp input values lower than 1 to 1.
In the case of the tangent, where the limit value is infinite,
clamp it to -inf or +inf.
