* Revert #5947 and disable the test
* Fix isDefaultPrevented and isPropagationStopped to not get nulled
This was a bug introduced by #5947. It's very confusing that they become nulled while stopPropagation/preventDefault don't.
* Add a comment
* Run Prettier
* Fix grammar
* Use %s in the console calls
* Add shared/warningWithStack
* Convert some warning callsites to warningWithStack
* Use warningInStack in shared utilities and remove unnecessary checks
* Replace more warning() calls with warningWithStack()
* Fixes after rebase + use warningWithStack in react
* Make warning have stack by default; warningWithoutStack opts out
* Forbid builds that may not use internals
* Revert newly added stacks
I changed my mind and want to keep this PR without functional changes. So we won't "fix" any warnings that are already missing stacks. We'll do it in follow-ups instead.
* Fix silly find/replace mistake
* Reorder imports
* Add protection against warning argument count mismatches
* Address review
* Fix getComponentName() for types with nested $$typeof
* Temporarily remove Profiler ID from messages
* Change getComponentName() signature to take just type
It doesn't actually need the whole Fiber.
* Remove getComponentName() forks in isomorphic and SSR
* Remove unnecessary .type access where we already have a type
* Remove unused type
* Remove event simulation of onChange events
It’s time to get rid of even more `ReactTestUtils.Simulate`s. In this PR
we remove the event simulation from all onChange tests. To do this, we
have to get a setter to the untracked value/checked props.
All remaining `ReactTestUtils.Simulate` calls are either testing
ReactTestUtils or assert that they do/don't throw.
* Use input instead of change event for all but checkbox, radio, and select
* Refactor ReactDebugCurrentFiber to use named exports
This makes the difference between it and ReactFiberCurrentFrame a bit clearer.
ReactDebugCurrentFiber is Fiber's own implementation.
ReactFiberCurrentFrame is the thing that holds a reference to the current implementation and delegates to it.
* Unify ReactFiberComponentTreeHook and ReactDebugCurrentFiber
Conceptually they're very related.
ReactFiberComponentTreeHook contains implementation details of reading Fiber's stack (both in DEV and PROD).
ReactDebugCurrentFiber contained a reference to the current fiber, and used the above utility.
It was confusing when to use which one. Colocating them makes it clearer what you could do with each method.
In the future, the plan is to stop using these methods explicitly in most places, and instead delegate to a warning system that includes stacks automatically. This change makes future refactorings simpler by colocating related logic.
* Rename methods to better reflect their meanings
Clarify which are DEV or PROD-only.
Clarify which can return null.
I believe the "work in progress only" was a mistake. I introduced it because I wasn't sure what guarantees we have around .return. But we know for sure that following a .return chain gives us an accurate stack even if we get into WIP trees because we don't have reparenting. So it's fine to relax that naming.
* Rename ReactDebugCurrentFiber -> ReactCurrentFiber
It's not completely DEV-only anymore.
Individual methods already specify whether they work in DEV or PROD in their names.
A recent change to the scheduler caused a regression when scheduling
many updates within a single batch. Added a test case that would
have caught this.
* Prepare placeholders before timing out
While a tree is suspended, prepare for the timeout by pre-rendering the
placeholder state.
This simplifies the implementation a bit because every render now
results in a completed tree.
* Suspend inside an already timed out Placeholder
A component should be able to suspend inside an already timed out
placeholder. The time at which the placeholder committed is used as
the start time for a subsequent suspend.
So, if a placeholder times out after 3 seconds, and an inner
placeholder has a threshold of 2 seconds, the inner placeholder will
not time out until 5 seconds total have elapsed.
* Fixes children when using dangerouslySetInnerHtml in a selected <option>
This fixes an inadvertent cast of undefined children to an empty string when creating an option tag that will be selected:
```
<select defaultValue="test">
<option value='test' dangerouslySetInnerHTML={{ __html: '‏ test'}} />
</select>
```
This causes an invariant error because both children and dangerouslySetInnerHTML are set.
* PR fix and new ReactDOMServerIntegrationForms test
* Account for null case
* Combine test cases into single test
* Add tests for failure cases
* Fix lint
* Inline fbjs/lib/emptyObject
* Explicit naming
* Compare to undefined
* Another approach for detecting whether we can mutate
Each renderer would have its own local LegacyRefsObject function.
While in general we don't want `instanceof`, here it lets us do a simple check: did *we* create the refs object?
Then we can mutate it.
If the check didn't pass, either we're attaching ref for the first time (so we know to use the constructor),
or (unlikely) we're attaching a ref to a component owned by another renderer. In this case, to avoid "losing"
refs, we assign them onto the new object. Even in that case it shouldn't "hop" between renderers anymore.
* Clearer naming
* Add test case for strings refs across renderers
* Use a shared empty object for refs by reading it from React
* Remove string refs from ReactART test
It's not currently possible to resetModules() between several renderers
without also resetting the `React` module. However, that leads to losing
the referential identity of the empty ref object, and thus subsequent
checks in the renderers for whether it is pooled fail (and cause assignments
to a frozen object).
This has always been the case, but we used to work around it by shimming
fbjs/lib/emptyObject in tests and preserving its referential identity.
This won't work anymore because we've inlined it. And preserving referential
identity of React itself wouldn't be great because it could be confusing during
testing (although we might want to revisit this in the future by moving its
stateful parts into a separate package).
For now, I'm removing string ref usage from this test because only this is
the only place in our tests where we hit this problem, and it's only
related to string refs, and not just ref mechanism in general.
* Simplify the condition
* Add isUsingKoreanIME function to check if a composition event was triggered by Korean IME
* Add Korean IME check alongside useFallbackCompositionData and disable fallback mode with Korean IME
* Remove rAF fork
**what is the change?:**
Undid https://github.com/facebook/react/pull/12837
**why make this change?:**
We originally forked rAF because we needed to pull in a particular
version of rAF internally at Facebook, to avoid grabbing the default
polyfilled version.
The longer term solution, until we can get rid of the global polyfill
behavior, is to initialize 'schedule' before the polyfilling happens.
Now that we have landed and synced
https://github.com/facebook/react/pull/12900 successfully, we can
initialize 'schedule' before the polyfill runs.
So we can remove the rAF fork. Here is how it will work:
1. Land this PR on Github.
2. Flarnie will quickly run a sync getting this change into www.
3. We delete the internal forked version of
'requestAnimationFrameForReact'.
4. We require 'schedule' in the polyfill file itself, before the
polyfilling happens.
**test plan:**
Flarnie will manually try the above steps locally and verify that things
work.
**issue:**
Internal task T29442940
* fix nits
* fix tests, fix changes from rebasing
* fix lint
* Use native event dispatching instead of Simulate or SimulateNative
In #12629 @gaearon suggested that it would be better to drop usage of
`ReactTestUtils.Simulate` and `ReactTestUtils.SimulateNative`. In this
PR I’m attempting at removing it from a lot of places with only a few
leftovers.
Those leftovers can be categorized into three groups:
1. Anything that tests that `SimulateNative` throws. This is a property
that native event dispatching doesn’t have so I can’t convert that
easily. Affected test suites: `EventPluginHub-test`,
`ReactBrowserEventEmitter-test`.
2. Anything that tests `ReactTestUtils` directly. Affected test suites:
`ReactBrowserEventEmitter-test` (this file has one test that reads
"should have mouse enter simulated by test utils"),
`ReactTestUtils-test`.
3. Anything that dispatches a `change` event. The reason here goes a bit
deeper and is rooted in the way we shim onChange. Usually when using
native event dispatching, you would set the node’s `.value` and then
dispatch the event. However inside [`inputValueTracking.js`][] we
install a setter on the node’s `.value` that will ignore the next
`change` event (I found [this][near-perfect-oninput-shim] article
from Sophie that explains that this is to avoid onChange when
updating the value via JavaScript).
All remaining usages of `Simulate` or `SimulateNative` can be avoided
by mounting the containers inside the `document` and dispatching native
events.
Here some remarks:
1. I’m using `Element#click()` instead of `dispatchEvent`. In the jsdom
changelog I read that `click()` now properly sets the correct values
(you can also verify it does the same thing by looking at the
[source][jsdom-source]).
2. I had to update jsdom in order to get `TouchEvent` constructors
working (and while doing so also updated jest). There was one
unexpected surprise: `ReactScheduler-test` was relying on not having
`window.performance` available. I’ve recreated the previous
environment by deleting this property from the global object.
3. I was a bit confused that `ReactTestUtils.renderIntoDocument()` does
not render into the document 🤷

* Make sure contains are unlinked from the document even if the test fails
* Remove unnecessary findDOMNode calls
* Don’t error when returning an empty Fragment
When a fragment is reconciled, we directly move onto it’s children.
Since an empty `<React.Fragment/>` will have children of `undefined`,
this would always throw.
To fix this, we bail out in those cases.
* Test the update path as well
* Reuse existing code path
* An even more explicit solution that also fixes Flow
It looks like we accidentally removed a fallback condition for the
event target in IE9 when we dropped some support for IE8. This commit
adds the event target specific support code back to getEventTarget.js
Fixes#12506
* Fixed an issue with nested contexts unwinding when server rendering. GitHub issue #12984
* Fixed an issue with search direction and stricter false checking
* Use decrement infix operator
* Streamlined existence checks
* Streamlined assignment. Removed redundant comment. Use null for array values
* Made prettier
* Relaxed type checking and improved comment
* Improve test coverage
This commit removes a reference to inst._wrapperState, which was the
old way of tracking input state in the stack renderer.
This means we no longer need to pass the instance into the associated
function, allowing us to eliminate an exception for IE (and a TODO).
* Set the correct initial value on input range
* Add description and update value diff check for input range
* add isHydrating argument and tests
* update node value according to isHydrating
* Do not set selection when prior selection is undefined (#12062)
`restoreSelection` did not account for input elements that have changed
type after the commit phase. The new `text` input supported selection
but the old `email` did not and `setSelection` was incorrectly trying to
restore `null` selection state.
We also extend input type check in selection capabilities to cover cases
where input type is `search`, `tel`, `url`, or `password`.
* Add link to HTML spec for element types and selection
* Add reset button to ReplaceEmailInput
This commit adds a button to restore the original state of the
ReplaceEmailInput fixture so that it can be run multiple times without
refreshing the page.
* Use local references to global things inside 'scheduler'
**what is the change?:**
See title
**why make this change?:**
We want to avoid initially calling one version of an API and then later
accessing a polyfilled version.
**test plan:**
Run existing tests.
* Shim ReactScheduler for www
**what is the change?:**
In 'www' we want to reference the separate build of ReactScheduler,
which allows treating it as a separate module internally.
**why make this change?:**
We need to require the ReactScheduler before our rAF polyfill activates,
in order to customize which custom behaviors we want.
This is also a step towards being able to experiment with using it
outside of React.
**test plan:**
Ran tests, ran the build, and ran `test-build`.
* Generate a bundle for fb-www
**what is the change?:**
See title
**why make this change?:**
Splitting out the 'schedule' module allows us to load it before
polyfills kick in for rAF and other APIs.
And long term we want to split this into a separate module anyway, this
is a step towards that.
**test plan:**
I'll run the sync next week and verify that this all works. :)
* ran prettier
* fix rebase issues
* Change names of variables used for holding globals
This commit fixes an issue where assigning an empty string to required
text inputs triggers the invalid state in Firefox (~60.0.1).
It does this by first comparing the initial state value to the current
value property on the text element. This:
1. Prevents the validation issue
2. Avoids an extra DOM Mutation in some cases
