This makes it easier to figure out where the docs live.
Googling for e.g. `react-addons-update` also works, but this should
make things easier for people that hyperclick directly to the source.
ReactDOMInput and a few other classes handle change event by scheduling updateWrapper() in an asap().
It gets executed after the batch, which confuses ReactPerf that expects all DOM writes to happen during a batch.
Since this implementation of ReactPerf relying on the stack is going away, let's plug the hole temporarily by ignoring DOM writes that occur during postponed updateWrapper(). In any case, they have no relation to actual calculations of wasted renders, as they don't occur due to updateComponent(), but rather due to onChange() special DOM behavior.
This fixes#5548
We intend to change the measurement format significantly in #6046. In order to introduce the new ReactPerf during 15.x release cycle, we are making the measurement structure opaque-ish in 15.0.
This is a little simpler (and a teeny tiny bit faster). The one in ReactCompositeComponent stays because of the way we create ReactCompositeComponentWrapper inside instantiateReactComponent.
We were shallow-rendering a component that used refs at FB so this can't go in as-is. It's a little unclear what we _should_ do though, since there is nothing to hold a ref to (since we're shallowly rendering) and we generally promise that child refs are resolved before a parent's componentDidMount. Also, changing shallow rendering to use the original `_renderValidatedComponent` (instead of `_renderValidatedComponentWithoutOwnerOrContext`) breaks tests because now the `_owner` field doesn't match up for `toEqual` (non-null in `getRenderOutput` but null if constructed in a test).
New module! With this, we have a new module that uses the component tree to store DOM nodes. Most of the logic in this file relates to markup adoption -- if we were to drop that (along with server rendering) this file could just be a `return inst._nativeNode;`.
This works with useCreateElement only because we need to reference each node as it's created.
Events is now the only thing using ReactMount.getNode -- I'll introduce pointers back from the DOM nodes (and a `ReactDOMComponentTree.getInstanceFromNode`) and make that work.
