## Summary
When an exception is raised by Java in a synchronous call from JS to Java, the Java portion of the stack trace is simply ignored when the exception is forwarded to JS. This problem doesn't exist for async calls. I did some digging to figure out why this works with async calls, but not sync calls, to get to the bottom of T52585087.
In T52585087, `TurboModuleRegistry.get<Spec>('I18nAssets')` fails because of a `NullPointerException` in Java. However, since there's no stack trace associated with the `NullPointerException`, it's hard to diagnose the problem.
## Asynchronous calls
ReactNative's NativeModules thread is a background thread on which we schedule asynchronous NativeModule method invocations. We spawn our background threads in Java using the [`MessageQueueThreadImpl`](https://fburl.com/diffusion/u0vdm5k3). Each thread is associated with a queue on which you can schedule some work. These `MessageQueueThread`s have a [C++ API](https://fburl.com/diffusion/596740d8) that we can use to schedule some work from C++.
NativeModule method invocations in JS produce a C++/Java boundry, because our JS executes C++, which executes the Java NativeModule method. But since the method is asynchronous, instead of invoking it immediately, we wrap it in a C++ lambda and use the C++ API of `MessageQueueThread` to schedule it to be invoked later. Therefore, when it actually invokes, we'll get Java invoking C++, which invokes Java.
When the NativeModule method (implemented in Java) throws an exception, fbjni will convert that exception into a `jni::JniException` and start unwinding the C++ stack. Eventually, this exception will reach the outermost Java/C++ boundry. Typically, at this point, the program would crash, but because we used fbjni to register all our native functions, our `jni::JniException` will automatically be converted into a regular Java exception. This exception will be caught by MessageQueueThreadHandler [here](https://fburl.com/diffusion/c4thoca7), and handled using our ExceptionHandler NativeModule.
## Synchronous calls
In synchronous execution, JS uses a `JSI::HostObject` to call the Java method directly. If the Java method throws an error, because we're using fbjni, that Java exception will be converted to a `jni::JniException` object, which will contain the stack tract of the Java object. However, from what I could gather, Hermes doesn't know about `jni::JniException`. So, simply ignore the stack trace associated with the Java exception, understanding only the exception message. Hence, all synchronous calls into Java only display the JS stack trace. What we really want is to build an platform-agnostic abstraction that understands `jni::JniException` (and whatever its analogue is in iOS, if any) and use that to bridge between Native and JS.
## Temporary Solution
We know that when NativeModules are created, we do a synchronous call from JS to C++ to Java. This synchronous call happens when you do a property access on the `NativeModules` object. Therefore, at the very least, to get to the bottom of T52585087, we could log all exceptions that are thrown whenever a NativeModule is created. This should help us get to the bottom of T52585087.

Summary:
## The Problem
1. `CatalystInstanceImpl` indirectly holds on to the `jsi::Runtime`. When you destroy `CatalystInstanceImpl`, you destroy the `jsi::Runtime`. As a part of reloading React Native, we destroy and re-create `CatalystInstanceImpl`, which destroys and re-creates the `jsi::Runtime`.
2. When JS passes in a callback to a TurboModule method, we take that callback (a `jsi::Function`) and wrap it in a Java `Callback` (implemented by `JCxxCallbackImpl`). This Java `Callback`, when executed, schedules the `jsi::Function` to be invoked on a Java thread at a later point in time. **Note:** The Java NativeModule can hold on to the Java `Callback` (and, by transitivity, the `jsi::Function`) for potentially forever.
3. It is a requirement of `jsi::Runtime` that all objects associated with the Runtime (ex: `jsi::Function`) must be destroyed before the Runtime itself is destroyed. See: https://fburl.com/m3mqk6wt
### jsi.h
```
/// .................................................... In addition, to
/// make shutdown safe, destruction of objects associated with the Runtime
/// must be destroyed before the Runtime is destroyed, or from the
/// destructor of a managed HostObject or HostFunction. Informally, this
/// means that the main source of unsafe behavior is to hold a jsi object
/// in a non-Runtime-managed object, and not clean it up before the Runtime
/// is shut down. If your lifecycle is such that avoiding this is hard,
/// you will probably need to do use your own locks.
class Runtime {
public:
virtual ~Runtime();
```
Therefore, when you delete `CatalystInstanceImpl`, you could end up with a situation where the `jsi::Runtime` is destroyed before all `jsi::Function`s are destroyed. In dev, this leads the program to crash when you reload the app after having used a TurboModule method that uses callbacks.
## The Solution
If the only reference to a `HostObject` or a `HostFunction` is in the JS Heap, then the `HostObject` and `HostFunction` destructors can destroy JSI objects. The TurboModule cache is the only thing, aside from the JS Heap, that holds a reference to all C++ TurboModules. But that cache (and the entire native side of `TurboModuleManager`) is destroyed when we call `mHybridData.resetNative()` in `TurboModuleManager.onCatalystInstanceDestroy()` in D16552730. (I verified this by commenting out `mHybridData.resetNative()` and placing a breakpoint in the destructor of `JavaTurboModule`). So, when we're cleaning up `TurboModuleManager`, the only reference to a Java TurboModule is the JS Heap. Therefore, it's safe and correct for us to destroy all `jsi::Function`s created by the Java TurboModule in `~JavaTurboModule`. So, in this diff, I keep a set of all `CallbackWrappers`, and explicitly call `destroy()` on them in the `JavaTurboModule` destructor. Note that since `~JavaTurboModule` accesses `callbackWrappers_`, it must be executed on the JS Thread, since `createJavaCallbackFromJSIFunction` also accesses `callbackWrappers_` on the JS Thread.
For additional safety, I also eagerly destroyed the `jsi::Function` after it's been invoked once. I'm not yet sure if we only want JS callbacks to only ever be invoked once. So, I've created a Task to document this work: T48128233.

Step 1 in removing the dependency on ReactContext from GuardedRunnable and other related classes. These are extensively by native modules and view managers, so in order to remove the bridge dependency from those modules we'll need to first decouple these classes from ReactContext. It turns out they only need ReactContext for its handleException method, which delegates out to product code. For backwards compatibility I'm exposing another NativeModuleExceptionManager in ReactContext that simply wraps its handleException method (since this interface already does everything we need).
I figured I'd keep around an extra constructor that still uses ReactContext for now instead of trying to migrate everything over at once.

Summary:
`setTimeout` inside a headless JS task does not always works; the function does not get invoked until the user starts an `Activity`.
This was attempted to be used in the context of widgets. When the widget update or user interaction causes the process and React context to be created, the headless JS task may run before other app-specific JS initialisation logic has completed. If it's not possible to change the behaviour of the pre-requisites to be synchronous, then the headless JS task blocks such asynchronous JS work that it may depend on. A primitive solution is the use of `setTimeout` in order to wait for the pre-conditions to be met before continuing with the rest of the headless JS task. But as the function passed to `setTimeout` is not always called, the task will not run to completion.
This PR solves this scenario by allowing the task to be retried again with a delay. If the task returns a promise that resolves to a `{'timeout': number}` object, `AppRegistry.js` will not notify that the task has finished as per master, instead it will tell `HeadlessJsContext` to `startTask` again (cleaning up any posted `Runnable`s beforehand) via a `Handler` within the `HeadlessJsContext`.
Documentation also updated here: https://github.com/facebook/react-native-website/pull/771
### AppRegistry.js
If the task provider does not return any data, or if the data it returns does not contain `timeout` as a number, then it behaves as `master`; notifies that the task has finished. If the response does contain `{timeout: number}`, then it will attempt to queue a retry. If that fails, then it will behaves as if the task provider returned no response i.e. behaves as `master` again. If the retry was successfully queued, then there is nothing to do as we do not want the `Service` to stop itself.
### HeadlessJsTaskSupportModule.java
Similar to notify start/finished, we simply check if the context is running, and if so, pass the request onto `HeadlessJsTaskContext`. The only difference here is that we return a `Promise`, so that `AppRegistry`, as above, knows whether the enqueuing failed and thus needs to perform the usual task clean-up.
### HeadlessJsTaskContext.java
Before retrying, we need to clean-up any timeout `Runnable`'s posted for the first attempt. Then we need to copy the task config so that if this retry (second attempt) also fails, then on the third attempt (second retry) we do not run into a consumed exception. This is also why in `startTask` we copy the config before putting it in the `Map`, so that the initial attempt does leave the config's in the map as consumed. Then we post a `Runnable` to call `startTask` on the main thread's `Handler`. We use the same `taskId` because the `Service` is keeping track of active task IDs in order to calculate whether it needs to `stopSelf`. This negates the need to inform the `Service` of a new task id and us having to remove the old one.

### Solution
This commit replaces the hardcoded instances of port 8081 on Android with a build configuration property. This allows setting of the port React Native Android connects to for the local build server.
For this change to work, there must also be an update to the react native CLI to pass along this setting:

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:
There is a small gap in the SynchronizedWeakHashSet implementation - the containsKey method of the WeakHashMap is modifying hence calling it during the iteration might cause ConcurrentModificationException. Added a command DO_IF_CONTAINS to safely handle this case.
[Android] [Bugfix] - Should fix a ConcurrentModificationException in onResume.

Summary:
This mechanism is heavily abused inside of the react-native and inside of the various native modules.
The main problem is that people don't remove their listeners and as result, we have memory leaks.
Some modules like UIManager, NativeAnimatedModule have resources holding Activity context. Those modules are held through a pretty long chain of dependencies.
In order to allow GC to collect those listeners, I replaced the CopyOnWriteSet by WeakHashMap and synchronized access. It is not such a big deal in terms of performance as those listeners are not called/modified too frequently but this prevents hard to debug memory leaks.
Changelog:
----------
Help reviewers and the release process by writing your own changelog entry. When the change doesn't impact React Native developers, it may be ommitted from the changelog for brevity. See below for an example.
[Android] [Fixed] - ReactContext - lifecycle listeners don't cause the leaks even if not removed.

Summary:
Instead of using measure specs to set certain yoga properties on the root node (like max width, auto width, specific width), use yoga's calculateLayout(width, height) instead. The measure specs will be stored in the shadow node. This allows us to remove duplicated code that processes the measure specs and allows us to remove other logic like the enableLayoutCalculation() method.
This diff also removes MeasureSpecProvider. MeasureSpecProvider was originally introduced to pass previously measured view measure specs to the initial creation of the root shadow node, but it turns out that this is unnecessary. We can update the root layout specs from the root view instead.

Summary:
This diff refactors JNI methods used by the Binding.cpp class in order to use ReadableMap instead of ReadableNativeMap
This will be helpful to provide a different implementation of ReadableMap from C++
