On latest (11.1 as of this commit) GCC, the following warning is
continuously issued during build:
warning: placement new constructing an object of type
'SafeNumeric<unsigned int>' and size '4' in a region of type
'uint32_t*' {aka 'unsigned int*'} and size '0' [-Wplacement-new=]
This happens because on 98ceb60eb4 the new operator override used
was dropped and replaced with standard placement new. GCC sees the
subtraction from the pointer and complains as it thinks that the
SafeNumeric is placed outside an allocation, not knowing that the
address requested is already inside one.
After suggestions, the false positive is silenced, with no other
changes.

* Exposed as utility functions.
* Not very useful for script, but vital for creating servers using native extensions.

The constructor was expecting a mutable pointer, while the passed pointer was immutable ( returns a const pointer), so the compilation was failing when iterating a constant .
|

It uses the (`const T &&... p_args`) forward reference, to avoid copying the
memory in case it's an rvalue, or pass a reference in case it's an lvalue.
This is an example:
```c++
PagedAllocator<btShapeBox> box_allocator;
btShapeBox* box = box_allocator.alloc( btVector3(1.0, 1.0, 1.0) );
```

With this commit the macro `memnew_placement` uses the standard memory
placement syntax: `new (mem) TheClass()`, and removes the outdated and
not used syntax:
```
_ALWAYS_INLINE_ void *operator new(size_t p_size, void *p_pointer, size_t check, const char *p_description) {
```
Thanks to this change, the function `memnew_placement` call is compatible with
any class, and can also initialize classes with non-empty constructor:
```
// This is valid, like before.
memnew_placement(mem, Variant);
// This works too:
memnew_placement(mem, Variant(123));
```

The `Math_INF` and `Math_NAN` defines were just aliases for those
constants, so we might as well use them directly.
Some portions of the code were already using `INFINITY` directly.

This PR implements range iterators in the base containers (Vector, Map, List, Pair Set).
Given several of these data structures will be replaced by more efficient versions, having a common iterator API will make this simpler.
Iterating can be done as follows (examples):
```C++
//Vector<String>
for(const String& I: vector) {
}
//List<String>
for(const String& I: list) {
}
//Map<String,int>
for(const KeyValue<String,int>&I : map) {
print_line("key: "+I.key+" value: "+itos(I.value));
}
//if intending to write the elements, reference can be used
//Map<String,int>
for(KeyValue<String,int>& I: map) {
I.value = 25;
//this will fail because key is always const
//I.key = "hello"
}
```
The containers are (for now) not STL compatible, since this would mean changing how they work internally (STL uses a special head/tail allocation for end(), while Godot Map/Set/List do not).
The idea is to change the Godot versions to be more compatible with STL, but this will happen after conversion to new iterators have taken place.

* Single function, easier to maintain.
* Updates materials properly when textures change.

Vector handles this silently by returning -1, and we should do the same here.
Otherwise we get errors when calling `find()` on e.g. a LocalVector of size 0,
while `find()` is expected to always work (if the parameters are invalid then
it doesn't find anything, so -1).
Fixup to #49925.

* Ability to allocate empty objects in RID_Owner, so RID_PtrOwner is not needed in most cases.
* Improves cache usage, as objects are now allocated together
* Should improve performance in 2D rendering

This commit adds the following properties to GeometryInstance3D: `visibility_range_begin`,
`visibility_range_begin_margin`, `visibility_range_end`, `visibility_range_end_margin`.
Together they define a range in which the GeometryInstance3D will be visible from the camera,
taking hysteresis into account for state changes. A begin or end value of 0 will be ignored,
so the visibility range can be open-ended in both directions.
This commit also adds the `visibility_parent` property to 'Node3D'.
Which defines the visibility parents of the node and its subtree (until
another parent is defined).
Visual instances with a visibility parent will only be visible when the parent, and all of its
ancestors recursively, are hidden because they are closer to the camera than their respective
`visibility_range_begin` thresholds.
Combining visibility ranges and visibility parents users can set-up a quick HLOD system
that shows high detail meshes when close (i.e buildings, trees) and merged low detail meshes
for far away groups (i.e. cities, woods).

* RingBuffer had no reason to be in this context
* A single buffer is used that can grow as much as the game needs.
This should make thread loading entirely reliable.

Or after punctuation. Tried to leave third-party stuff alone, unless it has
been heavily modified for Godot.
|
|
The code is based on the current version of thirdparty/vhacd and modified to use Godot's types and code style.
Additional changes:
- extended PagedAllocator to allow leaked objects
- applied patch from https://github.com/bulletphysics/bullet3/pull/3037

Port lawnjelly's dynamic BVH implementation from 3.x to be used in
both 2D and 3D broadphases.
Removed alternative broadphase implementations which are not meant to be
used anymore since they are much slower.
Includes changes in Rect2, Vector2, Vector3 that help with the template
implementation of the dynamic BVH by uniformizing the interface between
2D and 3D math.

Add fill method to Arrays and PackedArrays
|
|
We've been using standard C library functions `memcpy`/`memset` for these since
2016 with 67f65f66391327b2967a20a89c3627e1dd6e84eb.
There was still the possibility for third-party platform ports to override the
definitions with a custom header, but this doesn't seem useful anymore.

- For now everything imports multithreaded by default (should work I guess, let's test).
- Controllable per importer
Early test benchmark. 64 large textures (importing as lossless, _not_ as vram) on a mobile i7, 12 threads:
Importing goes down from 46 to 7 seconds.
For VRAM I will change the logic to use a compressing thread in a subsequent PR, as well as implementing Betsy.

Does the same internally for List and Vector<>, which includes all
PackedArray types.

And fix increment in `CowData` not being conditional anymore after the recent changes.

- Based on C++11's `atomic`
- Reworked `SafeRefCount` (based on the rewrite by @hpvb)
- Replaced free atomic functions by the new `SafeNumeric<T>`
- Replaced wrong cases of `volatile bool` by the new `SafeFlag`
- Platform-specific implementations no longer needed

-Rendering server now uses a split RID allocate/initialize internally, this allows generating RIDs immediately but initialization to happen later on the proper thread (as rendering APIs generally requiere to call on the right thread).
-RenderingServerWrapMT is no more, multithreading is done in RenderingServerDefault.
-Some functions like texture or mesh creation, when renderer supports it, can register and return immediately (so no waiting for server API to flush, and saving staging and command buffer memory).
-3D physics server changed to be made multithread friendly.
-Added PhysicsServer3DWrapMT to use 3D physics server from multiple threads.
-Disablet Bullet (too much effort to make multithread friendly, this needs to be fixed eventually).
|
|
- Based on C++11's `thread` and `thread_local`
- No more need to allocate-deallocate or check for null
- No pointer anymore, just a member variable
- Platform-specific implementations no longer needed (except for the few cases of non-portable functions)
- Simpler for `NO_THREADS`
- Thread ids are now the same across platforms (main is 1; others follow)
|
|
Added LocalVector unit tests.
|
|
-Reorganize thread work pool for rendering
-Fixes to make secondary command buffers to work (disabled because they need more testing)
|
|
|
|
So it can hopefully be made more cache efficient afterwards.

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 🎆
