Recently learned that components passed into `React.renderComponent` may not be the ones actually mounted. Also learned that it returns the mounted component. Added some documentation describing this.
Number('.1') === 0.1, and react uses dot-prefixed keys
for children. Whoops. Nuke the non-numeric requirement, and just
check a regex. This seems performant enough in micro-benchmarks:

We've been able to use `querySelectorAll` in all the browsers that we
support for some time now, but we haven't been able to test code that uses
it in the older version of `jsdom` that we were using, until recently.
Besides the general goal of modernizing our code, the impetus for this
specific change is that I'm trying to support testing without having to
render nodes into an actual document. The `.getElementsByName` method is
only defined on `document` and only works if the nodes you care about are
contained by the document.
On the other hand, `querySelectorAll` works on any DOM node, and allows a
more precise selection of just the `<input type="radio">` elements that
have the appropriate name.
IE8's implementation of `querySelectorAll` supports attribute-based
selectors, which is all we need here.
Little-known fact: instead of writing copies of compiled module files to
build/modules/, the bin/jsx-internal script actually just makes hard links
to the master versions of files in the .module-cache/, so re-populating
build/modules/ is very inexpensive.
Closes#856.
This codemods to shim any old-style JSX whitespace so that it renders the same as before.
Basically it sticks explicit `{' '}` spaces in where spaces are no longer implicit.
`cloneWithProps` uses `ReactPropTransferer`, which ignores the `key`
prop. See https://github.com/facebook/react/pull/713
However, this is not the case with `cloneWithProps` because when someone
is cloning a component and provides a key, they mean for the clone to
take it.
We've talked about this perf optimization for a while now. This prevents us from re-reconciling components that are above the component being
reconciled in the owner hierarchy.
See [Commoner's README.md](
https://github.com/benjamn/commoner#generating-multiple-files-from-one-source-module)
for further explanation of the new functionality.
Among other potential benefits, this upgrade allows us to generate source
maps as standalone files rather than appending them inline to every
compiled module file under `build/modules/` (see #833).
