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.
Closes#60.
Closes#71.
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.
Just a bit of byte savings for server rendering. Props to @benjamn for the base36 idea (and for making this diff easy).
With a little work we could probably get rid of the .r as well.
This changes React to throw when `ReactID.getNode()` fails to find a node. This method is used by two call sites:
- Implements `ReactComponent#getDOMNode`. This method already throws if a component is not mounted, and //all mounted components should be able to find their rendered root nodes//.
- Used by `ReactDOMIDOperations`. These call sites aleady assume that `getNode` returns a non-null. Currently, if the node is not found, this is the site that fatals (and the stack trace is much harder to debug).
The error message should make it //a lot// easier to debug unexpected DOM trees. In particular, this will help track down all the places where the browser inserts `<tbody>` unexpectedly.
This fixes a bug with components constructed with no owners, for example:
// Both the <div> and <span> have no owners.
React.renderComponent(<div><span /></div>, node);
They should have a composition level of 1 and their keys should be prefixed with 0 to indicate they were created without owners. However, they currently incorrectly get a composition level of 0 (which means that //their// children will have keys prefixed with 0, which is wrong).
The current `ReactInstanceHandles` has a bug where `findComponentRoot` barfs if it comes across a node that was not identified by React (via `ReactID`). This fixes that.
This was always a bug, but it became more apparent once we switched to `data-reactid` because arbitrary `document.createElement`'d nodes are much more likely to have an `id` than they are to have a `data-reactid`.
This final change is what we've all been waiting for.
Note that it no longer makes sense to use `document.getElementById` in
`getNode`, because that only ever worked with "id" attributes.
This prevents PhantomJS tests from hanging in the open-source React repo.
Until the advent of `"use strict"`, passing `null` as the context object
to `.call` or `.apply` resulted in `this` taking on the value of the
global object inside the invoked function.
Technically the `"use strict"` directive is supposed to make it possible
that `this === null`, but strict mode is not respected by all browsers,
including (unfortunately) PhantomJS.
Since these `expect`-ations are just testing binding behavior, let's not
make them also test strict mode `this` handling.
