Sunil Pai a457e02ae3 allow nested act()s from different renderers (#16039)
* allow nested `act()`s from different renderers

There are usecases where multiple renderers need to oprate inside an act() scope
- ReactDOM.render being used inside another component tree. The parent component will be rendered using ReactTestRenderer.create for a snapshot test or something.
- a ReactDOM instance interacting with a ReactTestRenderer instance (like for the new devtools)

This PR changes the way the acting sigils operate to allow for this. It keeps 2 booleans, one attached to React, one attached to the renderer. act() changes these values, and the workloop reads them to decide what warning to trigger.

I also renamed shouldWarnUnactedUpdates to warnsIfNotActing

react-dom

This package serves as the entry point to the DOM and server renderers for React. It is intended to be paired with the generic React package, which is shipped as react to npm.

Installation

npm install react react-dom

Usage

In the browser

var React = require('react');
var ReactDOM = require('react-dom');

class MyComponent extends React.Component {
  render() {
    return <div>Hello World</div>;
  }
}

ReactDOM.render(<MyComponent />, node);

On the server

var React = require('react');
var ReactDOMServer = require('react-dom/server');

class MyComponent extends React.Component {
  render() {
    return <div>Hello World</div>;
  }
}

ReactDOMServer.renderToString(<MyComponent />);
