This fixes UBSAN errors reported by running our testsuite, importing the
TPS demo, and running the TPS demo. I have tried, wherever possible, to
fix issues related to reported issues but not directly reported by UBSAN
because thse code paths just happened to not have been exercised in
these cases.
These fixes apply only to errors reported, and caused by, core/
The following things have been changed:
* Make sure there are no implicit sign changing casts in core.
* Explicitly type enums that are part of a public API such that users of
the API cannot pass in wrongly-sized values leading to potential stack
corruption.
* Ensure that memcpy is never called with invalid or null pointers as
this is undefined behavior, and when the engine is built with
optimizations turned on leads to memory corruption and hard to debug
crashes.
* Replace enum values only used as static values with constexpr static
const values instead. This has no runtime overhead. This makes it so
that the size of the enums is explicit.
* Make sure that nan and inf is handled consistently in String.
* Implement a _to_int template to ensure that all of the paths use the
same algorhithm, and correct the negative integer case.
* Changed the way the json serializer precision work, and added tests to
verify the new behavior. The behavior doesn't quite match master in
particulary for negative doubles as the original code tried to cast -inf
to an int. This then led to negative doubles losing all but one of
their decimal points when serializing. Behavior in GDScript remains
unchanged.
If an invalid type is supplied (which can still be done from a script),
a warning is printed (along with a workaround for ViewportTexture).
This also adds support for "negative" resource hints such as
"Texture2D,-ViewportTexture" to exclude one or more subclasses
from a class hint.

We now cache the Node*<>TreeItem* mapping in the SceneTreeEditor. This
allows us to make targeted updates to the Tree used to display the scene
tree in the editor.
Previously on almost all changes to the scene tree the editor would
rebuild the entire widget, causing a large number of deallocations an
allocations. We now carefully manipulate the Tree widget in-situ saving
a large number of these allocations.
In order to know what Nodes need to be updated we add a
editor_state_changed signal to Node, this is a TOOLS_ENABLED,
editor-only signal fired when changes to Node happen that are relevant
to editor state.
We also now make sure that when nodes are moved/renamed we don't check
expensive properties that cannot contain NodePaths. This saves a lot of
time when SceneTreeDock renames a node in a scene with a lot of
MeshInstances. This makes renaming nodes go from ~27 seconds to ~2
seconds on large scenes.
SceneTreeEditor instances will now also not do all of the potentially
expensive update work if they are invisible. This behavior is turned off
by default so it won't affect existing users. This change allows the
editor to only update SceneTreeEditors that actually in view. In
practice this means that for most changes instead of updating 6
SceneTreeEditors we only update 1 instantly, and the others only when
they become visible.
There is definitely more that could be done, but this is already a
massive improvement. In complex scenes we see an improvement of 10x,
things that used to take ~30 seconds now only take 2.
This fixes#83460
I want to thank KoBeWi, TokisanGames, a-johnston, aniel080400 for
their tireless testing. And AeioMuch for their testing and providing a
fix for the hover issue.
`ClassDB::can_instantiate()` and other reflection methods deadlock if the type is an script global class, when such script indirectly uses a not-yet-registered class. The reason is the `ClassDB` read lock is still held when invoking the `ResourceLoader` to load the class script, which may in turn need to lock for writing (for the class registration).
In particular, this happens with some types related to animation tree, that aren't registered at engine startup, but can happen with others, especially ones from the user. Registration statements are also added for the animation-related types that were lacking them.

How editor plugins use this feature:
1. Pick a unique translation domain name.
2. `_enter_tree()`: load translations into that translation domain.
3. Call `set_translation_domain()` for its root UI node.
4. `_exit_tree()`: remove that translation domain.
Plugins can also set the translation domain to `godot.editor` for
nested nodes that should use editor translations. `EditorFileDialog`
automatically does this.
- The main thread function and the collaborative wait functions have a much more similar structure than earlier, which yields (pun intended) better maintainability.
- Also, there are not assertions anymore about the reason for ending a wait being valid, because spurious awakes can happen and so the assert would fail without that indicating an issue.
Adds an optional (default false) compile option to enable comparing
`Ref` to `nullptr` to ensure correct use, as well as future expandsion
for more general dev checks (enabled with `dev_mode`)
This is useful for custom tagging of objects with properties (for example in Blender) and having this available in the editor for scripting.
- Adds import logic to propagate the parsed GLTF extras all the way to the resulting Node->meta
- Adds export logic to save Godot Object meta into GLTF extras
- Supports `nodes`, `meshes` and `materials` (in GLTF sense of the words)
Benefits:
- Simpler code. The main load function is renamed so it's apparent that it's not just a thread entry point anymore.
- Cache and thread modes of the original task are honored. A beautiful consequence of this is that, unlike formerly, re-issued loads can use the resource cache, which makes this mechanism much more performant.
- The newly added getter for caller task id in WorkerThreadPool allows to remove the custom tracking of that in ResourceLoader.
- The check to replace a cached resource and the replacement itself happen atomically. That fixes deadlock prevention leading to multiple resource instances of the same one on disk. As a side effect, it also makes the regular check for replace load mode more robust.
Changes to reduce the latency between changing node selection in the editor and seeing the new node reflected in the Inspector tab
- Use Vector instead of List for ThemeOwner::get_theme_type_dependencies and related functions
- Use Vector instead of List for ThemeContext::themes, set_themes(), and get_themes()
- Add ClassDB:get_inheritance_chain_nocheck to get all parent/ancestor classes at once, to avoid repeated ClassDB locking overhead
- Update BIND_THEME_ITEM macros and ThemeDB::update_class_instance_items to use provided StringNames for call to ThemeItemSetter, instead of creating a new StringName in each call
These changes reduce the time taken by EditorInspector::update_tree by around 30-35%
ResourceLoader:
- Fix invalid tokens being returned.
- Remove no longer written `ThreadLoadTask::dependent_path` and the code reading from it.
- Clear deadlock hazard by keeping the mutex unlocked during userland polling.
WorkerThreadPool:
- Include thread call queue override in the thread state reset set, which allows to simplify the code that handled that (imperfectly) in the ResourceLoader.
- Handle the mutex type correctly on entering an allowance zone.
CommandQueueMT:
- Handle the additional possibility of command buffer reallocation that mutex unlock allowance introduces.
Editor code is not instantiable outside of the editor
(1d14c054a1/core/object/class_db.cpp (L369)).
This is fine for editor plugins and the like, but the GDScript analyzer
balks at it, causing F5 runs to fail: #73525.
Instead, we really just want to know if the type is abstract - so add
a new ClassDB method to check that and nothing else.
Update core/object/class_db.cpp
