* Parse build script type and package names
This ensures that `yarn build core dom` includes DOM.
It also ensures that spaces like `yarn build "core, dom"` doesn't build EVERYTHING.
* Get rid of label in bundles config
Instead we just use the name from entry using fuzzy search.
There is one special case. If you put in `/index` or `/index.js`.
That allows to build things like `react/index` to only build isomorphic
where as `react` would build everything. Or `react-dom/index` to exclude
the server renderers.
* Instead of matching `/index.js` just append it to the search string
That way things like `yarn build react/` works too.
* Fixed `treeBaseDuration` by propagating its value from the suspended tree to the Fragment React temporarily wraps around it when showing the fallback UI.
* Fixed `actualDuration` by recording elapsed profiler time in the event of an error.
* Fixed `actualDuration` in concurrent mode by propagating the time spent rendering the suspending component to its parent.
Also updated ReactSuspensePlaceholder-test.internal to cover these new cases.
Fixes a bug where deletion effects in the primary tree were dropped
before entering the second render pass.
Because we no longer reset the effect list after the first render pass,
I've also moved the deletion of the fallback children to the complete
phase, after the tree successfully renders without suspending.
Will need to revisit this heuristic when we implement resuming.
* Recover from errors with a boundary in completion phase
* Use a separate field for completing unit of work
* Use a simpler fix with one boolean
* Reoder conditions
* Clarify which paths are DEV-only
* Move duplicated line out
* Make it clearer this code is DEV-only
Adds a check to the existing fuzz tester to confirm that the props are
set to the latest values in the commit phase. Only checks
componentDidUpdate; we already have unit tests for the other lifecycles,
so I think this is good enough. This is only a redundancy.
* Resolve defaultProps for Lazy components
* Make test fail again
* Undo the partial fix
* Make test output more compact
* Add a separate failing test for sync mode
* Clean up tests
* Add another update to both tests
* Resolve props for commit phase lifecycles
* Resolve prevProps for begin phase lifecycles
* Resolve prevProps for pre-commit lifecycles
* Only resolve props if element type differs
* Fix Flow
* Don't set instance.props/state during commit phase
This is an optimization. I'm not sure it's entirely safe. It's probably worth running internal tests and see if we can ever trigger a case where they're different.
This can mess with resuming.
* Keep setting instance.props/state before unmounting
This reverts part of the previous commit. It broke a test that verifies we use current props in componentWillUnmount if the fiber unmounts due to an error.
Setting to null isn't correct; setting to '' is. I opted to use dangerousStyleValue for consistency with the main path that we set things.
Fixes#14114.
Test Plan:
Verified setting to '' works in Chrome and IE11. (Setting to null works in Chrome but not in IE11.)
The `enableHooks` feature flag used to only control whether the API
was exposed on the React package. But now it also determines if the
dispatcher and implementation are included in the bundle.
We're using hooks in www, so I've switched the feature flag to `true`
in the www build.
(Alternatively, we could have two feature flags: one for the
implementation and dispatcher, and one for exposing the API on the
React package.)
* Avoid double commit by re-rendering immediately and reusing children
To support Suspense outside of concurrent mode, any component that
starts rendering must commit synchronously without being interrupted.
This means normal path, where we unwind the stack and try again from the
nearest Suspense boundary, won't work.
We used to have a special case where we commit the suspended tree in an
incomplete state. Then, in a subsequent commit, we re-render using the
fallback.
The first part — committing an incomplete tree — hasn't changed with
this PR. But I've changed the second part — now we render the fallback
children immediately, within the same commit.
* Add a failing test for remounting fallback in sync mode
* Add failing test for stuck Suspense fallback
* Toggle visibility of Suspense children in mutation phase, not layout
If parent reads visibility of children in a lifecycle, they should have
already updated.
This is required to use lazy.
Test Plan:
* Verified lazy works on a real world use case (shows spinner, shows real content).
* Verified that if I change the primary content's styles to have `display: 'none'` then it never appears (i.e., the code in `unhide` reads the styles successfully)
* Add debug tools package
* Add basic implementation
* Implement inspection of the current state of hooks using the fiber tree
* Support useContext hooks inspection by backtracking from the Fiber
I'm not sure this is safe because the return fibers may not be current
but close enough and it's fast.
We use this to set up the current values of the providers.
* rm copypasta
* Use lastIndexOf
Just in case. I don't know of any scenario where this can happen.
* Support ForwardRef
* Add test for memo and custom hooks
* Support defaultProps resolution
Check for existence of `setTimeout` and `clearTimeout` in the runtime
before using them, to ensure runtimes without them (like .NET ClearScript)
do not crash just by importing `react-dom`.
Mostly to catch this:
```js
useEffect(async () => {
// ...
return cleanup;
});
```
Is this too restrictive? Not sure if you would want to do like
```js
useEffect(() => ref.current.style.color = 'red');
```
which would give a false positive here. We can always relax it to only warn on Promises if people complain.
* Simplify imports in ReactChildFiber
* Import type first in ReactCurrentFiber
* Simplify imports in ReactFiberBeginWork
* Simplify imports in ReactFiberScheduler
* Simplify import in ReactFiberTreeReflection
* Simplify import in ReactFiberUnwindWork
* Remove repeated import
* Fix imports from ReactFiberExpirationTime
* Master imports in ReactFiberBeginWork
Removes the `enableDispatchCallback` feature flag and deletes the
associated code. An earlier version of the Hooks proposal included this
feature but we've since decided to remove it.
* [scheduler] Deadline object -> shouldYield
Instead of using a requestIdleCallback-style deadline object, expose a
method Scheduler.shouldYield that returns true if there's a higher
priority event in the queue.
* Nits
