Samuel Susla 85696298bf Fix yoga node owner getting out of sync with children
Summary:
Changelog: [internal]

# Problem
We have node A with N children.

Calling cloning constructor on `YogaLayoutableShadowNode` causes new `yogaNode_` to be created.
However if `fragment.children` is nil in cloning constructor, which basically says children were not changed, then the existing children's `owner` becomes invalid.

# Solution
In the clone constructor, always call `updateYogaChildren`. This updates yoga children with the new `owner`.

Nick Gerleman 427ba359e0 Stamp React Native Version Into C++ Code (#28036)
Summary:
The PlatformConstants native module exposes the ability to query the React
Native version used to build native code. This is managed on iOS and Android by
a version bumping script, which replaces module code based on a template.

It is currently difficult to accurately determine this version for out-of-tree C++
platforms (I.e. React Native Windows). The version of upstream react-native we resolve to is ultimately
dependent on the version of react-native chosen a peer dependency, which is not
neccesarily constant given a build of react-native-windows.

We could try to hack around this, and make our native build try to reason about
the resolved pacakge for react-native using a lockfile, but a much cleaner
solution is to embed version into C++ code, similar to what is done for Android
and iOS. This change does that, adding a header with React Native version and
updating the build stamping script to write to it.

Usage sample:

```c++
  constants["reactNativeVersion"] = folly::dynamic::object();
  constants["reactNativeVersion"]["major"] = ReactNativeVersion.Major;
  constants["reactNativeVersion"]["minor"] = ReactNativeVersion.Minor;
  constants["reactNativeVersion"]["patch"] = ReactNativeVersion.Patch;
```
## Changelog

[General] [Added] - Stamp React Native Version Into C++ Code
Pull Request resolved: https://github.com/facebook/react-native/pull/28036

Test Plan: Validated that the bumping script will accurately update the header, can compile under both MSVC and Clang.

Valentin Shergin 5bf6726bae Fabric: Stop using getChildrenSlice in ConcreteViewShadowNode
Summary:
D19963353 mentioned the infrastructure that re-routes methods calls related to adding and cloning children between YogaLayoutableShadowNode and ShadowNode. `cloneAndReplaceChild` is exactly this. It was implemented as a virtual method that is called from `ConcreteViewShadowNode`. The whole process requires building a list of children of some class and passing that as a list of pointers. Now we don't need it all that because we can call directly and statically. That change will allow us to simplify that infra even more in the future diffs.

With all previous changes, now we can implement `getYogaLayoutableChildren` inside `YogaLayoutableShadowNode` and call that statically. Eventually, that will allow us to remove templated `getChildrenSlice`. Previously the call for that method must be in `ConcreteViewShadowNode`, now it's not true anymore which we will use later to even better goodness.

Valentin Shergin fa773a1446 Fabric: Introducing ShadowNode traitCasts
Summary:
`traitCast` is a special form of static_cast that checks additional requirements (similar to `dynamic_cast`) before performing the cast. We will use that in many places in the coming diffs.

Restructuring the class hierarchy in the previous diff finally allows us to do static casts among ShadowNode and LayoutableShadowNode and other classes (previously it wasn't allowed because of lack of common base class).

Why we don't want to use `dynamic_cast`:
* It's expensive (and we need to do the cast on the hottest fragments of the framework). (See: (1) http://www.stroustrup.com/fast_dynamic_casting.pdf and (2) https://www.youtube.com/watch?v=ARYP83yNAWk Herb Sutter & proposal of `down_cast`).
* It's code-size inefficient, whereas `static_cast` has zero runtime and code-size overhead.
* Removing `dynamic_cast` will allow us finally to opt-out `RTTI` (additional code size and perm wins).

Valentin Shergin 432b434b55 Fabric: LayoutableShadowNode now inherits ShadowNode
Summary:
This is a very crucial change, everything else in this stack depends on it.
Here is the set of constraints that we have for ShadowNode-based class hierarchy:
* `ShadowNode` is a base class that defines basic operations on the nodes. It does not have virtual methods by design (virtual dispatch hurts performance; we want to limit and centralize that in `ComponentDescriptor`s).
* `ConcreteShadowNode<>` template *statically* wires particular `ShadowNode` and particular `Props` establishing a type-safe relationship between them ensured on compile time.
* Not all `ShadowNode`s are "layoutable", not all "layoutable" `ShadowNode`s use Yoga to do layout.
* Layotability (and YogaLayotability) feature is implemented as two classes `LayoutableShadowNode` and `YogaLayoutableShadowNode`. These classes essentially need to know something about the ShadowNode nature of the object (get the list of children or replace some children).

Before the change, `LayoutableShadowNode` and `YogaLayoutableShadowNode`classes did not inherit `ShadowNode` because we don't want to use *virtual inheritance* for `ShadowNode`: `ConcreteShadowNode<>` already inherits `ShadowNode`, so if we make `LayoutableShadowNode` inherits `ShadowNode`, we will have to somehow flatten this inheritance hierarchy (and the virtual inheritance is an answer to that). (Yes, C++ supports multiple inheritance and virtual inheritance.)
Before this change, we solved this dilemma this way: We have a subclass-template `ConcreteViewShadowNode<>` that inherits `ConcreteShadowNode<>` and `YogaLayoutableShadowNode`. Then, we had a bunch of methods that implement the rerouting of some functionality from `YogaLayoutableShadowNode` to `ShadowNode` and vise-versa. (See the diagram "Before".)

That worked fine, except the caveats:
* That wiring is nasty, complex, hard to reason about and overall limiting.
* There is no way to statically cast `LayoutableShadowNode` to `ShadowNode` (because there is no common base class). That forces us to use dynamic_cast on some perf critical paths (including layout, diffing and so on).
* Adding features that rely on interop between `LayoutableShadowNode` and `ShadowNode` is a nightmare.

It should be a better way to deal with this dilemma, and this diff implements a different approach: We can have a base class of `ConcreteShadowNode<>` as a template parameter. With this approach, we can make `LayoutableShadowNode` inherit `ShadowNode` and when we need to instantiate a `ConcreteShadowNode<>` that needs to be layoutable, we can just specify `YogaLayoutableShadowNode` as a base class. (See the diagram "After".)

This simple change will allow us to simplify a lot of things. The rest of the stack is about getting rid of unnecessary moving parts. Which will finally allow us to build "Inline Views" feature.

Joshua Gross 5be86695a3 AndroidTextInput uses default padding from Android theme
Summary:
For backwards-compatibility with Paper, we're implementing a feature in Fabric that will allow TextInputs to use the default padding from the theme in Android.

Note that this uses some pretty ugly hacks that probably shouldn't be used inside of components at all: looking directly at rawProps, overriding props/Yoga styles in the component descriptor, etc. I would (personally) really like to kill this feature entirely unless and until we can find a more elegant solution.

Changelog: [Internal]

TextInputs are still not pixel-perfect with Paper, but they're much closer, and the underline visual glitchiness is no longer an issue.

According to my tests, that's not completely true: if the function is defined to use strict mode via `"use strict"` either inside itself or in the file it was defined in, it does leave it `undefined`, but if the function is defined in non-strict mode, it sets `this` to the global object instead. This diff updates the documentation to reflect this.

Radek Pietruszewski 24e0bad8be Make JSCRuntime::createValue 35% faster (#27016)
Summary:
JSC does some sort of thread safety locking on every single JSC API call, which makes them ridiculously expensive for a large number of calls (such as when passing a large array over the RN bridge). It would be great if we could lock and unlock once for an entire sequence of JSC calls… but in the meantime, the less we call JSC the better.

In my benchmark environment (https://github.com/Nozbe/WatermelonDB/pull/541), the time spent in JSCRuntime::createValue went down from 1.07s to 0.69s by changing JSValueIsXXXX calls to a single JSValueGetType call.

Moti Zilberman 011cf3f884 JSStringToSTLString: truncate string on conversion failure
Summary:
[A recent change to JSStringToSTLString](https://github.com/facebook/react-native/pull/26955) causes a crash when the function is invoked with invalid UTF-16 data. The old behaviour, restored here, was to truncate the string before the first invalid character.

Here's how [the original code](https://github.com/facebook/react-native/blob/aee88b6843cea63d6aa0b5879ad6ef9da4701846/ReactCommon/jsi/JSCRuntime.cpp#L287) handled this case:
```
std::string JSStringToSTLString(JSStringRef str) {
  size_t maxBytes = JSStringGetMaximumUTF8CStringSize(str);
  // ^ maxBytes >= 1 regardless of str's contents
  std::vector<char> buffer(maxBytes);
  // ^ vector is zero initialised
  JSStringGetUTF8CString(str, buffer.data(), maxBytes);
  // ^ writes '\0' at the first invalid character and returns early (see JSC source code)
  return std::string(buffer.data());
  // ^ copies the string up to the first '\0'
}
```

See the JSC implementations of [`JSStringGetUTF8CString`](https://opensource.apple.com/source/JavaScriptCore/JavaScriptCore-7600.8.7/API/JSStringRef.cpp.auto.html) and [`convertUTF16ToUTF8`](https://opensource.apple.com/source/WTF/WTF-7600.7.2/wtf/unicode/UTF8.cpp.auto.html).

Based on the fact that `JSStringGetUTF8CString` *always* null-terminates the buffer - even when it bails out of converting an invalid string - here we're able to both

1. keep the fast path (not zero-initialising, not scanning for the null terminator) for the common case when the data is valid and JSStringGetUTF8CString returns a nonzero length; and
2. return the truncated string when JSStringGetUTF8CString returns an error code of 0, by scanning for the null terminator.

David Detlefs 14ac53363e Make synth trace write incrementally to a file.
Summary:
If we're using synth traces in production, we probably don't want to accumulate the trace in memory, and write it to a file in one big step when an error happens.  Rather, we'd like to write the trace incrementally, to a file: file system space is less scarse than memory, and doing it incrementally means less to do in the error handler.

This diff is the first step towards writing the synth trace incrementally.  The most difficult aspect of this is that in the existing code, on Android, the trace is written in the handler of an Intent.  Java-level operations on the Intent yielded a temporary filename under the application (so if the application is uninstalled, these temporary files are deleted).  We must do something similar, but choose the filename within native code, on construction of the SynthTrace object.  We copy what profiling does for this: assume the tmp dir is /data/data/<app>, where <app> can be found from reading /proc/self/cmdLine.

The SynthTrace constructor now takes a new argument: a unique_pointer to a stream.  If null, no trace file is written, and the SynthTrace just accumulates records in memory.  (This functionality is used during trace replay.) . If non-null, the trace is written to that stream.

The "write{BridgeTraffic}Trace..." methods become "flushAndDisable{BridgeTrafficTrace}" methods.

This diff is the first step towards incremental traces: the trace is still written at the end, but we've arranged that the place to write it is available at construction of the SynthTrace object.  Later diffs will move recording of static things (e.g., the RuntimeConfig) into the ctor, then actually make us write the trace to the file incrementally.

Samuel Susla bfa00a5d62 Fix ShadowNode.stateRevision value assignment
Summary:
# Problem

We calculate `stateRevision_` in constructor from children, but children change after shadowNode is initialised and before it is sealed. So the `stateRevision_` we calculate in constructor can be incorrect.

# Solution

Recalculate `stateRevision_` whenever children change. This can happen in two methods `ShadowNode::replaceChild` and `ShadowNode::appendChild`. This diff implements this solution.
