This allows most demos to run without any ubsan or asan errors. There
are still some things in thirdpart/ and some things in AudioServer that
needs a look but this fixes a lot of issues. This should help debug less
obvious issues, hopefully.
This fixes#25217 and fixes#25218
Fixes GCC 5 warnings of the form:
core/io/http_client.cpp:288:9: warning: enumeration value 'STATUS_SSL_HANDSHAKE_ERROR' not handled in switch [-Wswitch]
core/io/marshalls.cpp:806:9: warning: enumeration value 'AABB' not handled in switch [-Wswitch]
Those can be trivial cases where adding a default fallback is the solution,
or more complex issues/hidden bugs where missed values are actually meant
to be handled.
This allows more consistency in the manner we include core headers,
where previously there would be a mix of absolute, relative and
include path-dependent includes.
Shader compilation now keeps track of the discard key word.
Previously only variables were monitored. But discard, which needs
special treatment in some cases, went unnoticed by the compiler as
discard is not a variable but a flow control.
This commit adds monitoring for discard.
This commit makes operator[] on Vector const and adds a write proxy to it. From
now on writes to Vectors need to happen through the .write proxy. So for
instance:
Vector<int> vec;
vec.push_back(10);
std::cout << vec[0] << std::endl;
vec.write[0] = 20;
Failing to use the .write proxy will cause a compilation error.
In addition COWable datatypes can now embed a CowData pointer to their data.
This means that String, CharString, and VMap no longer use or derive from
Vector.
_ALWAYS_INLINE_ and _FORCE_INLINE_ are now equivalent for debug and non-debug
builds. This is a lot faster for Vector in the editor and while running tests.
The reason why this difference used to exist is because force-inlined methods
used to give a bad debugging experience. After extensive testing with modern
compilers this is no longer the case.
Note that gl_InstanceID is not supported in OpenGL ES 2.0,
so in the gles2 backend we assign it to 0.
Also clean up some duplicates/commented out code.
Fixes#20088.
The GLES3 shader compiler performs certain checks to enable or disable
the usage of certain uniform variables (and with that the set-up of UBOs).
If the `TIME` variable gets used inside the `vertex` function then the
renderer knows that it has to insert that value into the UBO.
The same applies to the `fragment` function.
The `light` function gets executed inside the fragment shader for every
light source that is relevant to the current pixel. If the `TIME` variable
gets used in that function then it needs to be present in the fragment-UBO.
The check for this was missing, so if a shader uses `TIME` inside `light`
but not inside `fragment` then the uniform will not actually be set up.
Using `misc/scripts/fix_headers.py` on all Godot files.
Some missing header guards were added, and the header inclusion order
was fixed in the Bullet module.
Schlick's approximation and GGX are orthogonal concepts.
Furthermore, it's usage so far has been inconsistent: we don't even use it with anisotropic SchlickGGX, and Burley (Disney) diffuse does use it while its name doesn't indicate it.
The use of Schlick's approximation in Burley and GGX is an implementation detail and doesn't need to be reflected to the namig.
