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.

## 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:
## Description
This diff introduces `NativeModulePerfLogger`, its BUCK, Cocoapod, android-ndk targets. This diff also wires up those targets into the React Native bridge and TurboModules targets, so that we get signal on if the code compiles.
This diff also introduces `TurboModulePerfLogger`, which is a namespace that holds the `NativeModulePerfLogger` that'll do perf-logging for TurboModules.
## How will perflogging work on iOS?
1. Each application will, during React Native initialization, create a NativeModule perf logger.
2. If TurboModules are enabled, we'll call `TurboModulePerfLogger::setInstance(perfLogger)`. If TurboModules are disabled, we'll call `NativeModulePerfLogger::setInstance(perfLogger)`.
3. TurboModules, when they're created and used, will log events via `TurboModulePerfLogger::getInstance()`. NativeModules (i.e: bridge modules), when they're created and used, will log events via the `NativeModulePerfLogger::getInstance()`.
> **Note:** The NativeModule system will log events for non-TurboModules as well. Maybe we should log events for only NativeModules that conform to the `TurboModule` interface, when TurboModules are disabled. This'll ensure a fair comparison between the two systems.
## How will perflogging work on Android?

Summary:
## Problems:
In my investigation of T65656635, I realized that the TurboModule system has a number of problems:
- In TurboModules, we use 1 lock to create n TurboModules. We should change this setup to n locks for n TurboModules. This way, two threads creating two different NativeModules don't compete for the same lock. Also, this is how it's done in Android (TurboModules & NativeModules), and iOS (NativeModules).
- In TurboModules, we don't calculate "requires main queue setup" faithfully. In the legacy system, if a NativeModule has a custom `init` method or a custom `constantsToExport` method, it "requires main queue setup" with a warning.
- In TurboModules, we don't create the NativeModule on the main queue, if "requires main queue setup" is true. Instead, the NativeModule is always created on the thread that requires it.
- In TurboModules, we don't perform any concurrency control around `id<RCTTurboModule>` setup. We should.
## What this diff does
In this diff, I fixed all the aforementioned issues by re-implementing `provideRCTTurboModule:`.
**Algorithm Notes:**
- **Gist:** When `n` threads race to create NativeModule `x`, only the first thread creates and sets up `x`. All others are told to wait. Once the creator thread finishes its job, it notifies all other waiting threads, which then wake up and return the newly created NativeModule. This algorithm was initially implemented in NativeModules for Android inside (ModuleHolder.java). I modified and implemented it for TurboModules for Android, and now this diff implements it for TurboModules for iOS.
- The TurboModule cache is replace with a TurboModuleHolder map. A TurboModuleHolder manages the creation lifecycle of a TurboModule, and holds a condition variable and mutex for doing concurrency control around it. When the bridge invalidates, in TurboModuleManager, we set the `invalidating` flag to true, which prevents the insertion of new entries into the TurboModuleHolder map.
- I added a `std::mutex` to serialize calls into the TurboModuleManagerDelegate, so we don't get races if the delegate isn't thread-safe.

Summary:
Adds `RootTag` as a valid type for arguments and return types in TurboModules (on both Android and iOS).
This will enable us to change `RootTag` into an opaque type. There are two compelling reasons to do this:
- JavaScript will no longer be able to safely depend on `RootTag` being a number (which means we can change this in the future).
- Call sites using `unstable_RootTagContext` will can get a `RootTag`, but call sites using the legacy `context.rootTag` will not. This means the opaque type will give us a strategy for migrating away from legacy context and eventually making `unstable_RootTagContext` the only way to access `RootTag`.

[iOS][Changed] Update ObjCTurboModule to use ObjCTurboModule::InitParams

fbshipit-source-id: 6584b0838dca082a69e8c14c7ca50c3568b95086
Summary:
## Problem
Every time we want to add, remove, or change the data passed to JavaTurboModule's constructor, we have to modify the C++ TurboModule codegen. (The same is true of `ObjCTurboModule`).
**Why was this necessary?**
- `JavaTurboModule` is effectively an abstract class whose constructor is always invoked by code-generated C++ classes. These C++ code-generated class constructors accept an argument list, and manually foward each and every item in that list to `JavaTurboModule::JavaTurboModule`.
## The fix
In this diff, I introduce a struct `JavaTurboModule::InitParams`, to represent a bag of arguments:
```
class JSI_EXPORT JavaTurboModule : public TurboModule {
public:
struct InitParams {
std::string moduleName;
jni::alias_ref<JTurboModule> instance;
std::shared_ptr<CallInvoker> jsInvoker;
std::shared_ptr<CallInvoker> nativeInvoker;
};
```
All `JavaTurboModules` will be created with an instance of this `InitParams` struct, instead of a list of arguments. Our code-generated C++ `jsi::HostObject` sublcasses will simply accept `InitParams` in their constructor, and forward it to `JavaTurboModule`'s constructor. This way, the codegen remains oblivious to what arguments JavaTurboModule requires.
## Okay, but why do we need this change now?
In the future, I plan to modify the constructor for `JavaTurboModule` to accept a performance logger, and a `RuntimeExecutor`. Similar modifications are planned for ObjC. For this reason, to avoid these four codemods, and any potential other codemods that occur because we're making modifications to `JavaTurboModule` or `ObjCTurboModule`, I'm launching this codemod, and the codemods in this stack.
## Misc Fix
- Previously, we were generating the TurboModule name from the Spec filename. This is incorrect because that name represents the spec name. Now, the name will be forwarded from TurboModuleManager in the `JavaTurboModule::InitParams` struct.
## Alternative implementations
I initially considered using `ContextContainer`, but decided against it because:
1. There are no type-safety guarantees.
2. I think it's a bit overkill for this scenario. We just need an opaque bag of data, and for our purposes a simple struct does the job fine.

Summary:
## Problem:
Let `A` be the set of all ObjC NativeModules that neither provide nor reqeust a method queue.
The TurboModule system dispatches all method calls to NativeModules in `A` synchronously to the JS thread. Here is the relevant logic:
**RCTTurboModule.mm:**
Link: https://fburl.com/diffusion/nz9gqje8
```
jsi::Value performMethodInvocation(
// ...
)
{
// ...
dispatch_queue_t methodQueue = NULL;
if ([instance_ conformsToProtocol:protocol(RCTBridgeModule)] &&
[instance_ respondsToSelector:selector(methodQueue)]) {
methodQueue = [instance_ performSelector:selector(methodQueue)];
}
if (methodQueue == NULL || methodQueue == RCTJSThread) {
// This is the default mode of execution: on JS thread.
block();
} else if (methodQueue == dispatch_get_main_queue()) {
```
**Why does this end up happening?**
1. NativeModules that request a method queue have `synthesize methodQueue = _methodQueue` in their `implementation` section. This generates a `methodQueue` getter for the NativeModule, and also creates an ivar to back that getter. The TurboModule system generates a `dispatch_queue_t` and uses ObjC's KVC API to write to the ivar. So in the above logic, for NativeModules that provide a method queue, methodQueue will neither be `NULL` nor `RCTJSThread`, so we don't dispatch synchronously to the JS thread.
2. NativeModules that provide a method queue will return something that is not `NULL` or something that is `RCTJSThread`. If they return `NULL`, the infra will throw an error early. If they return `RCTJSThread`, we'll dispatch synchronously to the JS thread, as we should (...wait. For async NativeModule methods that dispatch to `RCTJSThread`, should we dispatch asynchronously to the JS thread, via jsInvoker? **Edit:** Nope: https://fburl.com/diffusion/ivt9b40s.). In all other cases, we dispatch to appropriately to the respective method queue.
3. For NativeModules that neither provide nor request a method queue (i.e: NativeModules in `A`), they don't implement the `methodQueue` selector. Therefore, we dispatch synchronously to the JS thread.
## The fix (Part 1):
The first step towards fixing this problem is to generate `dispatch_queue_t`s for NativeModules in `A`.
That's what this diff accomplishes.

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.

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.

`RCTPerformanceLogger` is meant to be used to profile RN initialization. It supports a fixed list of markers. Each marker has a type, and there can only be one instance of it. This isn't suitable for logging events in the TurboModule system.

Summary:
This can cause a deadlock if the main thread synchronously calls into some JS that creates a TurboModule. However, this is also the behaviour of legacy NativeModules. Furthermore, this also greatly simplifies how we'll fix async method invocation in TurboModules: T55255146.

Summary:
Adding a `.clang-tidy` to a bunch of dirs under `react-native-github/ReactAndroid` and `react-native-github/ReactCommon`.
I don't want to add a single `.clang-tidy` at the root because we'll need more fine-grained control over what checks are enabled in different parts of the codebase; for example, fabric will and TM will probably have more checks enabled than older parts of the codebase that we're not actively modernizing, and the Hermes team probably wants its own config to be consistent with the rest of their codebase.
Starting off each `.clang-tidy` by only enabling clang-diagnostic; this is just to test that it's working. In the future, we'll work with the community to gradually enable more checks.

Summary:
After D19565499, the `LongLivedObjectCollection` will be cleared on the JS thread when the jsi::Runtime is deleted. This diff makes it so that we never hold strong references to `CallbackWrapper`s in our Android TurboModules infra. Therefore, we can leverage the changes in D19565499 to ensure that our `jsi::Function`s are deleted before the `jsi::Runtime`.
## Caveat
If you delete a TurboModule by itself, it's jsi::Functions that haven't been invoked won't be released. This is also the case for iOS. I plan to fix this for both iOS and Android at a later point in time.

Summary:
## Description
You're not supposed to hold on to JSI objects (ex: `jsi::Function`) past the point where their `jsi::Runtime` is deleted. Otherwise, we get a dangling pointer crash, like this: T60262810! Historically, this cleanup problem has always been really tricky to get right. With this diff, I hope to fix that problem once and for all by deleting all `jsi::Function`s when we delete the global `__turboModuleProxy` function.
## Current Setup
- The TurboModules infra uses weak references to `CallbackWrapper`s to hold on to the `jsi::Function`s passed from JS to ObjC.
- The LongLivedObjectCollection holds on to strong references to `CallbackWrapper`s. This ensures that the `jsi::Function`s aren't deleted prematurely. This also means that we can use `LongLivedObjectCollection` to delete all `CallbackWrappers`.
- `TurboModuleBinding` is the abstraction we use to install the global `__turboModuleProxy` function. It is owned by `TurboModuleManager`, and `TurboModuleManager` uses it to clear all references to `jsi::Function`s, when we delete all NativeModules.
## Solution
1. Transfer ownership of `TurboModuleBinding` from `TurboModuleManager` to the `__turboModuleProxy` function.
2. Clear the `LongLivedObjectCollection` when `TurboModuleBinding` is deleted.

Summary:
This is an incomplete effort to migrate from libfb to libfbjni. This is needed to restore the compatibility with Flipper and other FB Android projects that make use of FBJNI. Effectively, the outcome is that `fbjni` no longer has a checked-in copy here, but instead relies on the public artifacts published at github.com/facebookincubator/fbjni that can be deduplicated at build-time.
**A non-exhaustive list of tasks:**
* [X] Gradle builds the SDK and RNTester for Android.
* [X] Buck build for rntester works in OSS.
* [ ] Move from `java-only` release to full `fbjni` release. This requires finding a solution for stripping out `.so` files that the old `Android.mk` insists on including in the final artifacts and will clash with the full distribution.
* [ ] Import this and fix potential internal build issues.
* [ ] Verify that the changes made to the Hermes integration don't have any unintended consequences.

Summary:
In bridgeless mode, `RCTTurboModuleManager` is initialized with a nil bridge. This has mostly worked, since `RCTBridge` doesn't do too many things for TMM (some notifs and perf markers). The one important thing it provides is a `_jsInvoker`.
In bridgeless mode, up until this point `_jsInvoker` has been nil, and turbo modules were not able to call functions on the JS thread. This diff fixes that.

Summary:
RCTTiming was the only NativeModule that relied on converting `double`s to other `double`s via `RCTConvert`. RCTTiming was made into a regular NativeModule in D18410788, so it's safe to strip out this logic.
Hopefully, this reduces the memory consumption enough to reduce the OOMs reported in T45151932.
