If any component throws during reconciliation any subsequent reconciliation will break badly because ReactUpdates will be in an inconsistent state.
Add a finally block to prevent this.
Whenever a component is unmounted, we delete all listeners that might have been attached. This sucks because most applications, Facebook included, do not use every listener. There's a lot of wasted computation, especially if many components are mounted and unmounted.
This changes `deleteAllListeners` to more delete listeners more efficiently.
This fixes a bug with `ChangeEventPlugin` in IE8 and IE9. The extend of this bug includes:
- On IE8, not firing `onChange` immediately after `value` of an input is changed.
- On IE9, not firing `onChange` when backspacing.
Introduces a counterpart to mapChildren. It excludes empty children just as
mapChildren for compatibility. With might introduce something like
sliceChildrenIncludingEmptyValues at some point.
This behavior is new in Commoner v0.8.3, following the incorporation of
@jeffreylin's `DirWatcher` implementation:
https://github.com/jeffreylin/jsx_transformer_fun/blob/master/dirWatcher.js
Watching directories instead of files reduces the total number of open
files, and copes better with editors that save files by deleting and then
immediately recreating them.

If you are using bin/jsx independently, you may need to pass
--follow-requires to it if you rely on its dependency scanning.
Dependency scanning is still a good idea, but it's difficult to make it
work perfectly for everyone the first time they try bin/jsx.
Closes#131.
I still think the semantics of flattening children is valid but we'll
want to revert the flattening implementation while we solidify the
semantics and try another approach.
This reverts flattening so that this.props.children can once again be
either a single child, flat array or nested array.
mapChildren calls flattenChildren before doing anything else. This is
not the most efficient approach but I wanted to keep this inital diff
simple. It also ignores empty values for backwards compatibility.
We may want to try another approach where empty values are included
in the map.
Validation of keys is still done inside ReactComponent. Ideally I'd
like to extract that into a separate module but to avoid cyclic
dependencies, I'm keeping it in ReactComponent for now.
This fixes a race condition if the `onClick` tries to update the input or textarea (e.g. by calling `setState`):
<input
onClick={function(event) {
this.setState({somethingElse: true}); // Triggers an update.
// event.target.value is now equal to the old value, fail...
this.props.onChange(event);
})
/>
A dynamic value can be provided as a key to a child. Either as part of an object
or key property. This becomes part of the component's ID.
We have to be careful to escape this key before inserting it into the DOM since
it could become a vulnerability. We fixed this by escaping just the keys.
However, the current implementation breaks when you used escaped keys. The
internal value is escaped and the value used by getAttributeNode and
getElementById are both unescaped.
This fixes that by keeping the unescaped value internally but escaping it right
before the HTML is generated (like any other attribute).
This is important since business logic IDs (that should be used as keys)
contains characters that need to be escaped.
This changes `ReactDOMTextarea` to accept `defaultValue` and `value`. It will warn people about using children (but allow it and treat it as `defaultValue`, which is the current behavior).
Instead of simply logging the React ID of the `ancestorNode` when `findComponentRoot` fails, use a `try ... finally` to `console.error` the `ancestorNode`. This allows modern web inspectors to actually log a reference to the node (which may not have a React ID).
This means when people run into the problem, they will not have to execute:
require('ReactID').getNode(<copy+paste>);
NOTE: Admittedly, this will not log anything in IE8. That's fine, since IE8 has shitty console logging anyway.
