Ramanpreet Nara 3f77367883 Delay turbomodulejsijni so load until we need it in TurboModulePerfLogger
Summary:
Twilight doesn't have TMPerfLogging enabled. However, the TurboModule infra uses the TMPerfLogger java class everywhere, which loads the turbomodulejsijni library on class load. For some reason, this class load doesn't work, and causes Twilight prod to crash.

To mitigate that crash, this diff delays the so load until it's absolutely necessary, which is by the time we call jniEnableCppLogging. This should never be called in Twilight, because it doesn't have TMPerfLogging enabled. Therefore, the crash should disappear on Twilight.

David Vacca c291265508 Reintroduce CoreComponentsRegistry class
Summary:
This diff reintroduces the CoreComponentsRegistry class to register core components in the RN Tester app.

This class was previously deleted as part of D23091020 (https://github.com/facebook/react-native/commit/7fb1afae7f4b78970463e272b7d4f3230e84887d). Different from a past approach, this diff doesn't use inheritance for Hybrid classes (which seems to bring problems in Android 4 devices)

I'm planning to land this diff after I verify that D23091020 (https://github.com/facebook/react-native/commit/7fb1afae7f4b78970463e272b7d4f3230e84887d) fixed RC (maybe I will wait until sunday's cut)

Joshua Gross 774dec1e17 Introduce general API for setting C++ State from the View layer and getting a notification if it fails, with Android impl
Summary:
iOS will need to be implemented separately, but the shared C++ bits are in place.

Explanation: there is currently no way for the View layer to /know/ if an UpdateState call has succeeded or failed. Generally we just assume it succeeds, but if it fails we have no way of knowing or retrying.

This can cause some UI bugs. To mitigate this, I'm introducing a "failure" notification callback mechanism. The JNI bridging for this is a little complicated to avoid passing Runnable across the JNI, but it
should be much simpler on iOS.

In development this seems to make View components much more reliable.

Joshua Gross c8f571fdad Build ViewGroup mechanism for repeatedly retrying UpdateState until it succeeds
Summary:
With BackgroundExecutor+State Reconciliation, it is pretty common to have races where View layer UpdateState calls are thrown away.

Theoretically this is /always/ possible since C++ doesn't retry failed UpdateStates, we just try once and then bail. This is part 1 of improving our mechanisms for ensuring that State stays up-to-date from the View layer.

Joshua Gross 41fb336ff2 NativeAnimated: Fabric constructs partial animation graphs often; warn instead of crashing
Summary:
Due to subtle differences in lifecycle on the native side, as well as in JS, Fabric constructs partial graphs more frequently than non-Fabric RN did.

We still crash if we detect a cycle, which we check for more explicitly now; and we still always crash in non-Fabric. But if we detect a partial graph in Fabric,
we warn instead of crashing. We also print the state of the graph before crashing/warning, to assist in debugging in production.

Riley Dulin 63d20d3b1e Set the max heap size for OSS apps on Android to be 1 GB for Hermes
Summary:
The max heap size currently is 512 MB for OSS apps using Hermes on Android.

Some users (see https://github.com/facebook/hermes/issues/295) are experiencing
long pauses when reaching this ceiling.
Increasing this limit to 1 GB should reduce the frequency of these pauses occurring
for apps where the expected heap usage is near 512 MB.

Changelog: [Internal] Set Hermes's default max heap size to 1 GB
