Summary:
`CatalystInstanceImpl.cpp` now depends on `JSCallInvoker` and `JavaJSCallInvokerHolder`. Therefore, we need to correctly adjust the OSS builds to include these dependencies into the `libreactnativejni.so` file.
I made `ReactCommon/turbomodule/jscallinvoker` a static library `libjscallinvoker.a`. I then made `ReactAndroid/src/main/jni/react/jni`'s `libreactnativejni.so` depend on that static library. Also, because the Android NDK build system doesn't support header namespaces, I had to use the filesystem to simulate them. This is why all the `.cpp` and `.h` files for `JSCallInvoker` were moved to a `jsireact` folder.

Summary:
`TurboModuleManagerDelegate` is an abstract base class with the following API:
```
public TurboModule getModule(String name, ReactApplicationContext reactApplicationContext);
public CxxModuleWrapper getLegacyCxxModule(String name, ReactApplicationContext reactApplicationContext);
```
```
std::shared_ptr<TurboModule> getTurboModule(std::string name, jni::global_ref<JTurboModule> turboModule, std::shared_ptr<JSCallInvoker> jsInvoker) override;
std::shared_ptr<TurboModule> getTurboModule(std::string name, std::shared_ptr<JSCallInvoker> jsInvoker) override;
```
On the C++ side, when asked to provide a TurboModule with name `name`:
1. First, is this a CxxModule? If so:
1. Create the CxxModule and return
2. Otherwise:
1. Somehow get a Java instance of the TurboModule
2. If this Java object represents a CxxModule, like `FbReactLibSodiumModule`:
1. Grab the C++ part of this object, and wrap it in a `TurboCxxModule.cpp` and return.
3. Otherwise:
1. Wrap the Java object in a C++ HostObject and return.
This pseudocode demonstrates how we'd use `TurboModuleManagerDelegate` to implement `__turboModuleProxy`.
```
__turboModuleProxy(name, jsCallInvoker):
let cxxModule = TurboModuleManagerDelegate::getTurboModule(name, jsCallInvoker)
if (!cxxModule) {
return cxxModule;
}
// JNI Call that forwards to TurboModuleManagerDelegate.getLegacyCxxModule
let javaCxxModule : CxxModuleWrapper = TurboModuleManager.getLegacyCxxModule(name)
if (!javaCxxModule) {
return std::shared_ptr<react::TurboCxxModule>(javaCxxModule.getModule())
}
// JNI Call that forwards to TurboModuleManagerDelegate.getModule
let javaModule : TurboModule = TurboModuleManager.getModule(name)
if (!javaCxxModule) {
return TurboModuleManagerDelegate::getTurboModule(name, javaModule, jsCallInvoker)
}
return null

Summary:
JSCallInvoker requires a `std::weak_ptr<Instance>` to create. In our C++, `CatalystInstance` is responsible for creating this `Instance` object. This `CatalystInstance` C++ initialization is separate from the `TurboModuleManager` C++ initialization. Therefore, in this diff, I made `CatalystInstance` responsible for creating the `JSCallInvoker`. It then exposes the `JSCallInvoker` using a hybrid class called `JSCallInvokerHolder`, which contains a `std::shared_ptr<JSCallInvoker>` member variable. Using `CatalystInstance.getJSCallInvokerHolder()` in TurboModuleManager.java, we get a handle to this hybrid container. Then, we pass it this hybrid object to `TurboModuleManager::initHybrid`, which retrieves the `std::shared_ptr<JSCallInvoker>` from the `JavaJSCallInvokerHandler`.
There were a few cyclic dependencies, so I had to break down the buck targets:
- `CatalystInstanceImpl.java` depends on `JSCallInvokerHolderImpl.java`, and `TurboModuleManager.java` depends on classes that are packaged with `CatalystInstanceImpl.java`. So, I had to put `JSCallInvokerHolderImpl.java` in its own buck target.
- `CatalystInstance.cpp` depends on `JavaJSCallInvokerHolder.cpp`, and `TurboModuleManager.cpp` depends on classes that are build with `CatalystInstance.cpp`. So, I had to put `JavaJSCallInvokerHolder.cpp` in its own buck target. To make things simpler, I also moved `JSCallInvoker.{cpp,h}` files into the same buck target as `JavaJSCallInvokerHolder.{cpp,h}`.
I think these steps should be enough to create the TurboModuleManager without needing a bridge:
1. Make `JSCallInvoker` an abstract base class.
2. On Android, create another derived class of `JSCallInvoker` that doesn't depend on Instance.
3. Create `JavaJSCallInvokerHolder` using an instance of this new class somewhere in C++.
4. Pass this instance of `JavaJSCallInvokerHolder` to Java and use it to create/instatiate `TurboModuleManager`.
Regarding steps 1 and 2, we can also make JSCallInvoker accept a lambda.

Summary: Diffing algorithm uses a small map for every layer of shadow tree; that's a lot of maps. Luckily, it does not need a complex feature-full map (which is not free to allocate and use), it needs a tiny map with a dozen values. Why do we need to pay for what we don't use? This diff introduces a trivial map optimized for constraints that we have here. (See more details in the code.)

This is a small micro-optimization in Diffing algorithm.

Summary: Convert FabricUIManager.measure params to floats. Currently we convert parameters to ints across the JNI boundary, and then back to floats several times in Java. This is unnecessary and actually makes measurements trickier. The new implementation uses floats across the JNI boundary and uses Float.POSITIVE_INFINITY to represent unconstrained values, which is consistent with Fabric C++ as well.

Summary:
Previously we computed the list of nodes that need to be notified about layout changes using a list of mutation instructions. That was fine, but that's not really compatible with some other changes that I plan to make, so I decided to change it (make it better).
Besides the better design (debatable; fewer dependencies to unrelated moving pieces), here is why I believe the new way is more performant:
* The new approach has no `dynamic_casts`, whereas the previous has tons of them (two per a mutation). If a `dynamic_cast` takes 10 ns, for 500 nodes it can take up to 5ms only for casts. (Non-scientific assumption.)
* After removing dependency to mutation instruction, we can enable flattening for views which have `onLayout` event.

Makes bitfield getters/setters part of the bitfield ref template.
Since we introduced the tracking bit as template parameter in D14933022, every bitfield ref is an individual class anyway, and having function pointers doesn’t potentially lead to less code generation anyway.
Furthermore, this change can (in the absence of tracking bits) avoid less specialized templates dealing with refs, and to dynamic dispatch as a consequence.

Summary:
Different frameworks use different kinds of floats, optional floats, and floats with assigned unit names. All those approaches use different ways to represent undefined and empty values. To deal with it we need to have some helper functions.
So, this diff changes some ways that we convert some corner values (like NaN and empty value). That change is motivated by recent personal discoveries in this field that shifted my vision on that. E.g. ComponentKit does not use `CGFloatMax` value as `Infinite` value. UIKit is also (surprisingly to me) okay with using `Infitite` instead of `CGFloatMax`. And, in general, seems using really conceptually appropriate values (instead of UIKit-inspired ones) it's the right thing to do.

Summary:
We don't need to have those constants because this functionality is available in STL via `std::numeric_limits<YourParticularFloatType>::infinity()` (or `::min()` and `::max()`).
At the same time usage of `kFloatMax` was replaced with `Infinity` (which is a different value). Using `max` instead of `Infinity` was an attempt to mimic iOS/UIKit model where `Infinity` and `NaN` values usually are not being used. However, now this does not seem like a good idea. This concept is not used anywhere else (even in CK which is totally incompatible with it) and de-facto in RN we use it only in few places. So, let's use Infinity in places where it's logically appropriate.

Summary:

Adds `YGStyle::ValueRepr` to make code depending on the actual type easier to write.
So far, we have treated `yoga::detail::CompactValue` as an implementation detail, and that’s what it’s supposed to stay.
React Native Fabric has one value conversion overload that depends on that type, though, and used `decltype(YGStyle{}.margin()[0])` until now.
That’s problematic for two reasons:
- we want to constrain the parameter of `operator[](...)` to enum types, making the `0` unsuitable
- we want to return the non-const overload of the operator to return a custom `Ref` type, which is not the type needed by Fabric.
Making the storage type explicit allows to write more forward-compatible code.

In order to encapsulate property access on `YGStyle`, as a first measure we wrap all fields with accessors.
This will e.g. enable dynamic property storage and instrumentation in the future.
All accessors have a `const` version that allows direct access via `const&`. For mutation, bit fields are wrapped with a custom reference object.
This style allows for the least amount of changes in client code. Property access simply needs appended parens, eg `style.direction` becomes `style.direction`.

Summary:
UAs must adjust border radius values to fit a content box:
>>> Corner curves must not overlap: When the sum of any two adjacent border radii exceeds the size of the border box, UAs must proportionally reduce the used values of all border radii until none of them overlap.

Summary:
ShadowTree commits happen concurrently with limited synchronization that only ensures the correctness of the commit from ShadowTree perspective.
At the same time artifacts of the commit () needs to be delivered (also concurrently) to the proper thread and executed in order (not-concurrently). To achieve this we need some synchronization mechanism on the receiving (mounting) side. This class implements this process.
Practically, this diff fixes a problem with glitching UI during the very first render of Fabric screen.

Summary:
Registries, providers, providers of registries, registres of providers. All that can be really confusing, but that represents best the constraints and desires that we have:
* We need to be able to register components on-the-fly (so we need a mechanism that will propagate changes);
* We don't want to register ComponentDescriptors separately from ComponentView classes;
* C++ not always gives us abstractions that we want (e.g. pointers to constructors).
After the change, we can remove the whole Buck target that has a bunch of handwritten boilerplate code.
There is a still room for polish and removing some concepts, types or classes but this diff is already huge.

Summary:
ComponentDescriptorProvider represents unified way to create a particular descriptor.
Now all ComponentViews (which support RCTComponentViewProtocol) expose a `ComponentDescriptorProvider` which will allow creating and registering ComponentDescriptor instances for all visual components automatically as a part of ComponentView registration process.
Don't panic, everything is still being as explicit as it always was, no magic involved; we just will have only one registration step instead of two parallel.
That also opens a way to register components on the fly.

Summary:
Motivation:
* We don't use them much, and we already have `at`-methods, which are better.
* We don't want to expose `ComponentDescriptor`s as shared pointers (because it's not clear, not so performant, and because we don't want to store them as shared pointer in the future);
* In idiomatic C++ `[]` operator has mutating semantic, that's not what we want to communicate via the interface of the class.

Summary:
If you call into a Java method (from C++ using JNI) that raises an exception, the JNI call won't actually raise a C++ error. Instead, the `JNIEnv` will record the pending Java exception and the C++ will continue executing as normal. This is bad because the next time you call into JNI, the app will actually crash, unless you explicitly cleared the exception using `JNIEnv::ExceptionClear()` before the JNI call.
With respect to TurboModules, we need to make sure that RedBoxes show up whenever a native methods raise an exception. We also don't want the app to crash when a JNI method call fails because of a raised exception. Therefore, in this diff, I raise a C++ exception if `JNIEnv::ExceptionCheck()` is true.

Summary:
If the return type of a TurboModule method is `Promise`, the infra should create a `com.facebook.react.bridge.Promise` object and pass it as the final argument of the TurboModule Java method call. The Java TurboModule method can then do some work asynchronously and either resolve or reject the promise at some point in time.

Summary:
This diff replaces all MountItem classes with a bunch of static C functions that do the same job as classes did.
Seems, originally we overestimated the complexity of MountItem classes and that they ended up being notably trivial. Now, maintaining that even longer would mean paying for abstractions and allocations that we don't really need and writing a lot of tedious code.
Besides that, the one particular change that will be introduced in the coming diffs is not particularly fit very well in the existing class-based model.
This change also should save us many hundreds of allocations and atomic counters bumps, so maybe we can get a millisecond-or-two win.
This diff does not introduce any practical behavioral/logical changes in the mounting layer.

Before, the diffing algorithm created the following list of instructions:
```
insert(A, B, 0)
insert(B, C, 0)
insert(B, D, 1)
```
After this diff, the insert instructions are going to be:

Summary:
This allows an unsupported component to be rendered as a "unimplemented view" for better visualization of which component is missing. It is off by default, but configurable in the component factory.
For now, the layout simply follows regular <View />, which means the width/height etc is based on the react component styling. The side effect is that components with 0 height/width won't show up at all.

Summary:
For props that expects a struct/object value, like scrollView's contentInset, not all keys may be present. For example:
```
<ScrollView ... contentInset={{top: 10}} />
```
In this example, `left`, `bottom`, and `right` should just default to 0 (or whatever the default is in the platform). Before this fix, an exception occured when calling `fromRawValue()` because it is assuming all 4 keys are present in the prop bag. However, only `top` key was present in this example.
To fix this, we have to loop through the available keys in the prop bag, then assign the values accordingly.

Regenerating the “golden master” tests with chrome surfaced different bugs around `align-content`:
- a misunderstanding that values in `align-content` only applied *if there is only one line.* In fact, it applies *every time* a container is set to `flex-wrap: wrap`. Chrome had this wrong, and as such our tests were generated with incorrect parameters.
- empty children growing to the cross axis size of the container, even when `align-content` is different from `stretch`. This was implemented incorrectly in Chrome as well. Here, we fix it with an extra check.

Summary:
Informal `DebugStringConvertible` interface serves the same purpose as `DebugStringConvertible` abstract class (providing universal pretty-printing interface) but relies on C++ static overloading instead of virtual dispatch.
This approach has some advantages and disadvantages:
Pros:
* It's more clear and scoped. It's simpler to implement debug-printing functionality aside of normal production code.
* It's more composable.
* It allows print types that are not classes.
* For some classes using `DebugStringConvertible` means that we have to use virtual inheritance (which might be undesirable and affect *production* performance (if a compiler isn't smart enough to remove empty base class).
* For some highly lean classes (that designed to be as small as possible) adding base (even empty-in-prod) classes kinda... smells.
Cons:
The particular implementations cannot rely on dynamic dispatch which can complicate printing classes with meaningful differences between sampling classes (e.g. ShadowNode subclasses). That's why we don't remove `DebugStringConvertible` class yet.
