Currently, GDScripts who are only loaded through `ResourceLoader::load()`,
like Autoloads, do not have a pathway to announce there is an error in their
code. This contributes to significant confusion in error projects when
autoloads are involved. At least partially closes#78230.
1. Validation layers on Windows were complaining w/
VUID-VkSwapchainCreateInfoKHR-surface-01270 that we were not calling
vkGetPhysicalDeviceSurfaceSupportKHR before vkCreateSwapchainKHR.
2. Godot was only calling vkGetPhysicalDeviceSurfaceSupportKHR at
startup, but it should be doing this for every window w/ a new surface
it wants to create, not just the first one.
- In practice this will likely not make a difference. If
vkGetPhysicalDeviceSurfaceSupportKHR returns false after initialization,
there's nothing we can do about it and it is likely because something
else went terribly wrong, which is why the error message is worded like
that.
- This is mostly to shut up validation layers. Though technically,
the layers are right.
3. Do not call vkGetPhysicalDeviceSurfaceSupportKHR on queues we don't
even plan on ever using. We don't know how drivers will react to that
(e.g. they may preemptetively allocate resources to support presentation
on exotic queues, instead of just saying no). Just behave like every
other Vulkan app out there.
The first time a shader is compiled Godot performs the following:
```cpp
for (uint32_t i = 0; i < SHADER_STAGE_MAX; i++) {
if
(spirv_data.push_constant_stages_mask.has_flag((ShaderStage)(1 << i))) {
binary_data.push_constant_vk_stages_mask |=
shader_stage_masks[i];
}
}
```
However binary_data.push_constant_vk_stages_mask is never initialized to
0 and thus contains garbage data or'ed with the good data.
This value is used by push constants (and many other things) thus it can
be a big deal.
Fortunately because the relevant flags are always guaranteed to be set
(but not guaranteed to be unset), the damage is restricted to:
1. Performance (unnecessary flushing & over-excessive barriers)
2. Overwriting push descriptors already set (this would be serious,
doesn't seem to be an issue)
3. Driver implementations going crazy when they see bits set they don't
expect (unknown if this is an issue)
This uninitialized value is later saved into the binary cache.
Valgrind is able to detect this bug on the first run, but not on the
subsequent ones because they data comes from a file.
cache_file_version has been bumped to force rebuild of all cached
shaders. Because the ones generated so far are compromised.
This assumes that operators are called usually with the same type of
operands as the first time. So it stores the types of the first run and
if matched it uses an optimized path by calling the validated operator
function directly. Otherwise it uses the regular untyped evaluator.
With this change, if operators do use the same type they run quite
faster. OTOH, if the types mismatch it takes longer to run than they
would with the previous code.
This commit fixes#78140
When the scene was re-imported with non-default values of some settings, re-importing it again using default values for those settings didn't have the effect.
The problem was that when handling the reimport, a wrong dictionary of the settings was used.
