Summary:
TurboModule eager initialization is a bit dangerous if we get it wrong, which we did (twice): T69449176.
This diff gates TurboModule eager init behind a MC, so that we can control (i.e: turn off/on, and do gradually rollout of) TurobModule eager initialization in isolation from the larger TurboModules experiment.

Summary:
## Why?
1. RCTTurboModuleLookupDelegate sounds a bit nebulous.
2. In JS and Java, we use a `TurboModuleRegistry` interface to require TurboModules. So, this diff will make JS, Java, and ObjC consistent.

Summary:
## Context
1. In FBReactModule jsExecutorForBridge, we asynchronously initialize a list of TurboModules on the main queue: https://fburl.com/diffusion/i56wi3px
2. After initializing the bridge, we start executing the JS bundle, here: https://github.com/facebook/react-native/blob/e23e9328aa164d0a70fe4f16042c982e7801d924/React/CxxBridge/RCTCxxBridge.mm#L414-L417. Since bridge initialization knows nothing about TurboModule eager initialization, this happens concurrently with 1, and starts requiring NativeModules/TurboModules on the JS thread.
## The Race
1. Both the main thread and the JS thread race to create a TurboModule that requires main queue setup.
2. The JS thread wins, and starts creating the TurboModule. Meanwhile, the main thread blocks, waiting on a signal here, in RCTTurboModuleManager: https://github.com/facebook/react-native/blob/e23e9328aa164d0a70fe4f16042c982e7801d924/ReactCommon/turbomodule/core/platform/ios/RCTTurboModuleManager.mm#L430
3. The JS thread tries to dispatch_sync to the main queue to setup the TurboModule because the TurboModule requires main queue setup, here: https://github.com/facebook/react-native/blob/e23e9328aa164d0a70fe4f16042c982e7801d924/ReactCommon/turbomodule/core/platform/ios/RCTTurboModuleManager.mm#L402
4. We deadlock.
## The fix
Succinctly, NativeModule eager initialization finishes before execute the JS bundle, but TurboModule initialization doesn't. This diff corrects that mistake.
The changes in this diff:
1. The RN application via the TurboModuleManager delegate can now optionally provide the names of all eagerly initialized TurboModules by implementing two methods `getEagerInitModuleNames`, `getEagerInitMainQueueModuleNames`.
2. The TurboModuleManager grabs these two lists from the delegate, and exposes them to its owner via the `RCTTurboModuleRegistry` protocol.
3. The RCTCxxBridge, which already owns a `id<RCTTurboModuleRegistry>` object, uses it to eagerly initialize the TurboModules in these two lists with the correct timing requirements.
This is exactly how we implement eager initialization in Android.
**Note:** Right now, phase one and two of TurboModule eager initialization happen after phase one and two of NativeModule eager initialization. We could make the timing even more correct by initializing the TurboModules at the exact same time we initialize the NativeModules. However, that would require a bit more surgery on the bridge, and the bridge delegate. I think this is good enough for now.

Summary:
## Context
- If a NativeModule requires main queue setup, its `constantsToExport` method is executed on the main queue.
- In the TurboModule system, `constantsToExport` or `getConstants` is treated like a regular synchronous NativeModule method. Therefore, it's always executed on the JS thread.
This difference in behaviour is dangerous when we're A/B testing the TurboModule infra: One could write a NativeModule that requires main queue setup, and have it expose constants that access objects/state only accessible on the UI thread. This NativeModule would work fine in the legacy infra, which could be the case if the NativeModule author is testing locally. But once it ships to prod, it may run with the TurboModule system, and crash the application. To mitigate this risk, I'm removing this special main queue execution of `constantsToExport` from the legacy infrastructure.
## Consequences
- If a NativeModule's `constantsToExport` method accesses objects/state only accessible on the UI thread, it must do so by explicitly scheduling work on the main thread. I wrote up a codemod to fix this for our OSS modules: D21797048.
- Eagerly initialized NativeModules that required main queue setup had their constants calculated eagerly. After the changes in this diff, those NativeModules will have their constants calculated lazily. I don't think this is a big deal because only a handful of NativeModules are eagerly initialized, and eagerly initialized NativeModules are going away anyway.

Summary:
## Motivation
We got this crash T67304907, which shows a `EXC_BAD_ACCESS / KERN_INVALID_ADDRESS` when calling this line:
```
NativeModulePerfLogger::getInstance().asyncMethodCallBatchPreprocessStart();
```
There are no arguments in that call, so I figured the only error could be when we try to invoke `getInstance()` or `asyncMethodCallBatchPreprocessStart()`.
This diff:
1. Removes the `NativeModulePerfLogger::getInstance()` bit. Now NativeModulePerfLogger is used via regular static C functions. So, there's no way that simply invoking one of the logging functions crashes the application: there's no vtable lookup.
2. Inside each logging function, when perf-logging is disabled, the global perflogger should be `nullptr`. This diff makes it so that in that case, we won't execute any code in the control group of the perf-logging experiment.
## Changes
**How do we enable NativeModule perf-logging?**
- Previously:
- `NativeModulePerfLogger::setInstance(std::make_shared<FBReactNativeModulePerfLogger>(...))`
- `TurboModulePerfLogger::setInstance(std::make_shared<FBReactNativeModulePerfLogger>(...))`.
- Now:
- `BridgeNativeModulePerfLogger::enableLogging(std::make_unique<FBReactNativeModulePerfLogger>(...))`
- `TurboModulePerfLogger::enableLogging(std::make_unique<FBReactNativeModulePerfLogger>(...))`
**How do we do NativeModule perf-logging now?**
- Previously:
- `NativeModulePerfLogger::getInstance().command(...args)`
- `TurboModulePerfLogger::getInstance().command(...args)`.
- Now:
- `BridgeNativeModulePerfLogger::command(...args)`
- `TurboModulePerfLogger::command(...args)`.
The benefit of this approach is that each method in `BridgeNativeModulePerfLogger` is guarded with an if check. Example:
```
void moduleCreateConstructStart(const char *moduleName, int32_t id) {
NativeModulePerfLogger *logger = g_perfLogger.get();
if (logger != nullptr) {
logger->moduleCreateConstructStart(moduleName, id);
}
}
```
Therefore, we don't actually execute any code when perf-logging is disabled.

## Motivation
This rename will fix the following CircleCI build failures:

## Investigation
We have 4 podspec targets that map to the same header namespace (i.e: `header_dir`) `ReactCommon`:
- **New:** `React-perflogger`: Directory is `ReactCommon/preflogger`, and contains `NativeModulePerfLogger.{h,cpp}`.
- `React-runtimeexecutor`: Directory is `ReactCommon/runtimeexecutor`, and contains only `RuntimeExecutor.h`
- `React-callinvoker`: Directory is `ReactCommon/callinvoker`, and contains only `CallInvoker.h`
- `ReactCommon/turbomodule/core`: Directory is `ReactCommon/turbomodule`, and contains C++ files, as well has header files.
**The problem:**
We couldn't import headers from `React-perflogger` in `ReactCommon/turbomodule/core` files.
**The cause:**
I'm not entirely sure why, but I was able to discern the following two rules by playing around with the podspecs:
1. If your podspec target has a cpp file, it'll generate a framework when `USE_FRAMEWORKS=1`.
2. Two different frameworks cannot map to the same `module_name` or `header_dir`. (Why? No clue. But something breaks silently when this is the case).
So, this is what happened when I landed `React-perflogger` (D21443610):
1. The TurboModules code generates the `ReactCommon` framework that uses the `ReactCommon` header namespace.
2. `React-runtimeexecutor` and `React-callinvoker` also used the `ReactCommon` header namespace. However, neither generate a framework because of Rule 1.
3. When I comitted `React-perflogger`, I introduced a second framework that competed with the `ReactCommon` framework (i.e: TurboModules code) for the `ReactCommon` header namespace. Rule 2 violation.
## Thoughts on renaming
- `<perflogger/NativeModulePerfLogger.h>` is too generic, and the `perflogger` namepsace is used internally within FB.
- `<react/perflogger/NativeModulePerfLogger.h>` matches our fabric header format, but I'm pretty sure that slashes aren't allowed in `header_dir`: I tested this and it didn't work. IIRC, only alphanumeric and underscore are valid characters for `header_dir` or `module_name`. So, I opted to just use `reactperflogger`.

Summary:
There's a corner case where:
* The bridge gets invalidated, and native modules are cleaning up themselves (but not done yet)
* Something asks for a NativeModule instance - ideally it should just get nil at this point
* If TM Manager is invalidating, we get nil correctly, but we continue thru the old NativeModule lookup logic
* The latter will fail anyway, and would throw a redbox (RCTLogError).
So, if the bridge is invalidated, if TM Manager returns nil, we should just return nil for old NativeModule lookup.
The module of interest is RCTImageLoader, which was requested by RCTImageView on deallocation. The problem is RCTImageView got dealloc'ed **after** the bridge has been invalidated, so the lookup would always fail...
Bonus: RCTImageView should just keep a weak ref to the RCTImageLoader, so that:
* if the imageLoader is still alive on image dealloc, it can still access them (last minute "meaningless" cleanup)
* if the imageLoader is gone, then the image deallocation doesn't do anything

Summary:
`RCTTurboModuleManager` will create a native `CallInvoker` for each ObjC NativeModule. This `CallInvoker` will be used to dispatch calls from JS to native. Before passing the native `CallInvoker` to the `ObjCTurboModule`, it'll first use `RCTCxxBridge decorateNativeCallInvoker` to get a bridge-aware decorated native `CallInvoker`. That way, the bridge remains informed about async TurboModule method calls that took place since the last time it was flushed. This ensures that we don't end up dispatching `onBatchComplete` any less with TurboModules on than we do with TurboModules off.

Summary:
## Context
For now, assume TurboModules doesn't exist.
**What happens when we call an async NativeModule method?**
Everytime JS calls an async NativeModule method, we don't immediately execute it. The legacy infra pushes the call into some queue managed by `MessageQueue.js`. This queue is "flushed" or "emptied" by the following events:
- **Flushed:** A C++ -> JS call. NativeModule async methods can called with an `onSuccess` and/or `onFail` callback(s). Calling `NativeToJsBridge::invokeCallback` to invoke one of these callbacks is one way for ObjC++/C++/Java to call into JS. Another way is via JSModule method calls, which are initiated by `NativeToJsBridge::callFunction`.
- **Flushed:** When `JSIExecutor::flush` is called. Since TurboModules don't exist, this only happens when we call `JSIExecutor::loadApplicationScript`.
- **Emptied:** When more than 5 ms have passed, and the queue hasn't been flushed/emptied, on the next async NativeModule method call, we add to the queue. Afterwards, we empty it, and invoke all the NativeModule method calls.
**So, what's the difference between flushed and emptied?**
> Note: These are two terms I just made up, but the distinction is important.
If the queue was "flushed", and it contained at least one NativeModule method call, `JsToNativeBridge` dispatches the `onBatchComplete` event. On Android, the UIManager module is the only module that listens to this event. This `onBatchComplete` event doesn't fire if the queue was "emptied".
**Why does any of this matter?**
1. TurboModules exist.
2. We need the TurboModules infra to have `JsToNativeBridge` dispatch `onBatchComplete`, which depends on:
- **Problem 1:** The queue being flushed on calls into JS from Java/C++/ObjC++.
- **Problem 2:** There being queued up NativeModule async method calls when the queue is flushed.
In D14656466, fkgozali fixed Problem 1 by making every C++/Java/Obj -> JS call from TurboModules also execute `JSIExecutor::flush()`. This means that, with TurboModules, we flush the NativeModule async method call queue as often as we do without TurboModules. So far, so good. However, we still have one big problem: As we convert more NativeModules to TurboModules, the average size of the queue of NativeModule method calls will become smaller and smaller, because more NativeModule method calls will be TurboModule method calls. This queue will more often be empty than not. Therefore, we'll end up dispatching the `onBatchComplete` event less often with TurboModules enabled. So, somehow, when we're about to flush the NativeModule method call queue, we need `JsToNativeBridge` to understand that we've executed TurboModule method calls in the batch. These calls would have normally been queued, which would have led the queue size to be non-zero. So if, during a batch, some TurboModule async method calls were executed, `JsToNativeBridge` should dispatch `onBatchComplete`.
**So, what does this diff do?**
1. Make `Instance` responsible for creating the JS `CallInvoker`.
2. Make `NativeToJsBridge` responsible for creating the native `CallInvoker`. `Instance` calls into `NativeToJsBridge` to get the native `CallInvoker`.
3. Hook up `CatalystInstanceImpl`, the Android bridge, with the new JS `CallInvoker`, and the new native `CallInvoker`. This fixes `onBatchComplete` on Android. iOS work is pending.

## Problems
Repro steps:
1. Disable Fabric (because CMD + R doesn't work with Fabric right now).
2. Open up Marketplace and hit `CMD + OPT + R`
3. **Observe:** The progress bar doesn't show up right away. It also doesn't actually show progress.
https://pxl.cl/140g1
RN Support post: https://fb.workplace.com/groups/rn.support/permalink/3437652016283389/
## Fixes
The first problem is that progress bar doesn't actually show progress.
**Fix:** Bundle load progress is updated in `RCTCxxBridge`, where we first require `RCTDevLoadingView`, and then call its `updateProgress` method. Previously, we wouldn't lazily load `RCTDevLoadingView`, it already didn't exist. Lazily loading `RCTDevLoadingView` causes the progress view to show up. Here: https://pxl.cl/140gt
If you look at the above video, you'll notice there are two stages to the progress bar: stage 1 displays the actual progress. Stage 2 prompts that we're downloading the JS bundle. As you can see, stage 1 and stage 2 have different background colors, even though both of them are green.
**Fix:** I adjusted the JS to match the Native color. Here: https://pxl.cl/140gT
We're almost there, but the progress bar is dismissed twice?
**Fix:** I dug into the code, and the reason why was because when we hit `CMD + R`, we invalidate the bridge, and immediately re-initialize it. This means that we asynchronously invalidate the old TurboModuleManager, and immediately create a brand new one. Therefore, two `RCTDevLoadingView` modules can (and do) exist at once. So, I moved `RCTDevLoadingView` to be an instance member of `FBReactModule`, to ensure that it doesn't get cleaned up and re-created when TurboModuleManager is deleted and re-created. This finally fixed the progress bar jank:

```
} else if (self->_reactInstance) {
self->_reactInstance->loadScriptFromString(std::make_unique<NSDataBigString>(script),
```
The thread doing the reset is doing so switching the executorClass to WebSocketExecutor.
In the scenario we crash, the packager has a bundle ready and quickly returns it, though its a 34MB string being passed to NSDataBigString which must be taking long enough for the other thread to get a chance to reset.

Summary:
RCTAssertJSThread is a specific to RCTCxxBridge assert that ensured that the code is executed on JavaScript thread. It was here from the very beginning. Now we need to remove it.
Reasons:
- The overall concept of limiting the execution of JavaScript code to a single thread is gone. Now we think about this as some queue, not thread. Fabric heavily relies on that and that asserts fires in Fabric.
- The assert is already far from being trivial: it checks for a custom executor, and if it's not nil, it does not fire. We can introduce another special flag for Fabric that will also disable that... but that's pointless. Such kinda asserts should not be complex to be useful.
- This asserts was used only in two places, and both of them are not exposed as public API.

Summary:
This diff adds a new reloading method reloadWithReason that allows callers to provide a reason for why a reload was requested.
This reason is useful for understanding why users are reloading, and why Fast Refresh is bailing out to a full reload. I also updated the places we reload with the reasons listed below.
**Standard native reasons:**
- Redbox
- Command
- Global hotkey
- Profiling controls
- Dev menu - reload
- Dev menu - reset to default
- Dev menu - apply changes
**From JavaScript (added in a later diff):**
- Fast Refresh - Unrecoverable
- Fast Refresh - No root boundary
- Fast Refresh - Invalidated boundary
- Fast Refresh - Invalidated root boundary
**Misc reasons and fallback for when a reason is unavailable:**
- Unknown from JS
- Uncategorized from JS
- Unknown from bridge
- Unknown from cxx bridge
- Requested from bridge
- Custom executor class reset

Summary:
@public
With this guard removed, the functionality is the same in RCT_DEV and non-RCT_DEV builds because RCTDevSettings will return NO (or not exist) in non-RCT_DEV builds, so this code will not be run.
Pros to this approach:
- Hot loading can be enabled in a non-RCT_DEV build
Cons:
- all builds now have this extra block of code, even if it won't be run
If the cons are too strong, I can move this code into a new RCT_DEFINE that inherits from RCT_DEV. (but notably, can be overridden)

Summary:
As we saw in D15947985, and later traced down to D5623623, the `hot` option isn't used by Metro anymore. The relevant transforms _always_ run in DEV regardless of the option.
Given that, it doesn't make sense that enabling or disabling Hot Reloading forces a full refresh. This significantly raises the usage barrier because **currently, you might have to wait ~20 seconds (on a large app) to just start using Hot Reloading when you're already in the middle of some screen.** So you just end up not using it.
This diff changes enabling/disabling Hot Reloading to be _instant_.
Here's how it works:
1. Now we always send the necessary info to the client via the new `HMRClient.setup()` function. It creates a Metro HMR client instance, but only actually sets up the socket if Hot Reloading is on.
2. The "Enable Hot Reloading" menu no longer forces a reload. Instead, it calls `HMRClient.enable()` which lazily sets up a socket (at most once).
3. The "Disable Hot Reloading" menu also doesn't trigger a refresh now. Instead, it calls `HMRClient.disable()`. We don't actually tear down the socket here because it's a pain to deal with race conditions and such. Instead, we keep the connection — but we _ignore the updates_ that come in while we're disabled.
4. As a result, it is possible to enable and disable it many times during a single session. (Updates while disabled would be ignored — which has a risk of making your running app inconsistent — but I'd argue it's expected and is worth it. You can always save a particular file to force it to update once the mode is on.)
5. In order to support "ignoring" updates, Metro's `HMRClient` (not to be confused with RN's module) now supports a `shouldApplyUpdates` field. The RN module uses it to disable handling updates when the mode is off.
6. In case there is an error that makes hot reloading unavailable (such as the server disconnecting), we surface the error only if the mode is on. If the mode is off, we stash the error message in the `_hmrUnavailableReason` variable, and display it next time you try to enable Hot Reloading.

Summary:
Some ObjC NativeModules conform to `RCTInvalidating` protocol and implements `invalidate` method. This is typically used to clean things up during bridge teardown or reload. In TurboModule system the invalidate method can be replaced by pure destructors, but for backward compatibility, we call existing invalidate method on each module during teardown.
This also cleans up all existing LongLivedObject's.

Summary:
In the case where the first rootView we load enables Fabric, the UIManagerBinding ended up calling AppRegistry (JS) too early, before the bridge was fully ready. This means AppRegistry wasn't set up yet, causing redbox.
To fix this, RuntimeExecutor impl should ask the bridge to queue the callback instead of asking the MessageQueueThread directly. MessageQueueThread only works well IFF the bridge is alive, but it has no knowledge about whether the bridge is alive or not. To support this, we add `invokeAsync` impl to the RCTCxxBridge.

Summary:
There is a timing issue when reloading the bridge (in dev mode) and the tear down of the TurboModules. This causes `Instance` to never get freed, hence the "bridge" isn't cleaning up properly. The side effect can be bogus error saying that it's unable to find a module.
To address this, JSCallInvoker should just take in weak_ptr<Instance>.

Summary: When calling into JS (e.g. promise resolve/reject, callback) in TurboModule, we bypass the bridge's message queue. At times this causes race condition, where there are a bunch of pending UI operations (in RCTUImanager) waiting to be flushed, but nothing adds calls to the message queue. Usually tapping the screen will trigger the flush because we're sending down touch events to JS.
