This reverts https://github.com/facebook/react/pull/576
This approach mutates the default props for the instance on each update,
which causes incorrect behavior. discussed with @balpert. can look into
cloning but this unbreaks.
This leaves statics as a way to define static methods and properties
that will be accessible on the return value of `React.createClass`
without changing the current spec.
It is valuable to know when the number of children in a TransitionGroup is going
to increase or decrease, since we might want to apply extra animations.
For instance, when used with overflow:auto, we might want to apply different css
based on it overflowing or not - to do this we need to calculate this after new
nodes has entered and after nodes has been removed.
This moves the static properties off of the root object and into
a 'statics' property. Then they are made available on the constructor so
they can be used directly and in mixins.
Summary:
e.g.
propTypes: {
foo: React.PropTypes.oneOfType([
React.PropTypes.string,
React.PropTypes.number
]);
}
to do this, I exposed a `.weak` chainable validator that returns instead of throws, e.g.
React.PropTypes.string.isRequired.weak
React.PropTypes.string.weak
which returns true or false. Technically, `React.PropTypes.string.weak.isRequired` also exists, but `oneOfType` will never call it. Might be useful to people creating custom validators though.
Since we use keyMirror() and invariant() messages are only shown in __DEV__, we don't have to do manual constant->string translation. Also fixes a few
undefined keys that just happened to work before.
As an added bonus, the jasmine web interface now groups tests by file.
Test Plan:
grunt test passes on b2507066, the parent of 566f8b2e (which committed a workaround for buggy module mocking).
We can already access the DOM node using `this.getDOMNode()`. Passing it as an argument was a bad decision.
Previous API:
```
componentDidMount(DOMElement rootNode)
componentDidUpdate(object prevProps, object prevState, object prevContext, DOMElement rootNode)
```
Next API:
```
componentDidMount()
componentDidUpdate(object prevProps, object prevState, object prevContext)
```
