Summary

Closes #22796

How did you test this change?

  • yarn test ReactFiberNewContext
  • CI
  • [ ] codesandbox of linked issue Can't test codesandbox since react-test-renderer isn't built by Codesandbox CI. Though I tested it locally by adding context._currentRenderer2 = null; to popProvider in react-test-renderer.development.js.

} else {
ReactNoop.render(<App value={1} />);
}
expect(Scheduler).toFlushAndYield(['Foo', 'Foo']);

The test above ("warns if multiple renderers concurrently render the same context") did not commit here. Without committing I would expect the warning. But here we actually commit so I don't think we should warn.

What I find odd is that ReactFizzNewContext does handle the _currentRenderer in popProvider but does not reset it but set it it to rendererSigil i.e. push and pop do the same things to _currentRenderer:

context._currentRenderer2 = rendererSigil;

Maybe we should actually restore _currentRenderer and not just reset it?

Moved down since we push(value) -> push(rendererN) so we need to pop(rendererN) -> pop(value)

This seems correct. There is an equivalent implementation for ReactFizzNewContext which probably should get the same treatment

I was expecting this to land in 18.3 or 19 but I'm still getting the warnings... Is that expected?

Same here, here's a reproduction repo https://stackoverflow.com/q/78512399/4957288

Also, hii @iammerrick 😱 ❤️ Long time no see, how are you??? Never expected React warnings to be bringing people together like that 😂

18.3 only included deprecation warnings and no other changes such as this. It will be part of React 19 though.
