We currently automatically render empty components in place of mocks. However,
we were accidentally transferring the props from the mocked descriptor to the
empty component placeholder. Even children.
This change just cleans that up and should only affect unit tests.
Trying to make the event a bit more performant for events.
Feel free to reject this because the API inevitably isn't great. It's good for perf though, and since we're only using `accumulate` in very restrained places, I think we're fine.
`accumulateInto` is `accumulate` that mutates more and allocates less. I kept `accumulate` in case we want that in the future.
The spec changed to allow null & undefined sources without throwing.
Now our code depends on this new behavior. The only browser that
implements Object.assign has also updated its native implementation to
this behavior (Firefox Nightly).
The biggest change: instead of calling functions directly, we now use
React.createElement to wrap.
The other big change: this removes the need for the @jsx pragma.
Instead we'll parse everything, assume React is in scope,
and only look for the actual XJS parts in the AST (as opposed to only
runing the transform when @jsx was specified in the docblock).
Note: this is actually a series of commits internally and should have
been syned out in pieces over the past several weeks.
This fixes some log spew since this pattern is deprecated. This doesn't use
the validator in the descriptor creation so there's no prop type checks here.
I guess that's fine because we still have the second prop type checks.
We need to use ReactLegacyDescriptor because the constructor here will be a
legacy factory that we need to unwrap.
constructAndRenderComponent should be deprecated.
Replace plain function calls to legacy factories with createFactory or
createElement. For ReactDOMComponents the type should be replaced with
strings.
Because we don't have easy access to ReactLegacyDescriptor from within
React, we need to use the .type property to extract the real class.
This will go away later and is covered by unit tests.
This moves all logic around legacy descriptors to ReactLegacyDescriptor. This
is responsible for the layer that knows that createClass exports a legacy
factory. When passed one of these classes, it unwraps it to be a real class.
If it is passed a non legacy factory, it is assumed to be a non-react component
that needs to be invoked as a plain function.
The semantic change is that a descriptor is now always returned if passed a
legacy factory. Even if that factory is a mock. A mock would previously return
undefined.
For mocks, I treat the factory as the authoritative function. I call it to extract
the instance or fill it with an empty component placeholder.
Additionally, I make the classes take props as the first argument to the
constructor. This is what the new class system will do.
We currently need to set up some internals by calling the internal construct
method. Instead of doing that automatically in the constructor, I now move that
to a second pass so that mocks can get the plain props.
This means that we can assert that a mock has been called once it's mounted
with it's final props. Instead of the descriptor factory being called.
The reason I chose to submit this is because it was initially unclear from the docs that the transition group needed to already be mounted in order for it to work properly.
