* Ignore checked in copies of React 15 bundles in attribute fixture
**what is the change?:**
We checked in bundles of React v15 to run comparisons of attribute
behavior on DOM elements between 15 and 16.
This commit tells prettier and eslint to ignore those files, and fixes a
prettier lint in one other file from that fixture.
**why make this change?:**
To get CI passing.
**test plan:**
`yarn prettier` doesn't change anything, eslint passes
**issue:**
* update README for attribute table fixture
* run prettier again
* Wrap warning() calls in a DEV check for RN_* builds too.
* Wrapped several warning() imports and calls in if-DEV checks.
* Removed a useless variable (allTypesByEventName) and loop from ReactNativeBridgeEventPlugin.
* Use GCC instead of Uglify for UMD/NODE bundles
* Prettier run
* Fixes fixtures that were alterated by Pretter and trailing function commas
* prettier on prettier
* updated prettier config
* altered prettier config slightly
* Reverted prettier changes
* updated results.json
* Remove PooledClass from FallbackCompositionState
The only module that uses FallbackCompositonState is BeforeInputEventPlugin. The way its structured means there can only be a single instance of FallbackCompositionState at any given time (stored in a local variable at the top-level) so we don't really need pooling here at all. Instead, a single object is now stored in FallbackCompositionState, and access (initializing, reseting, getting data) is gaurded by the exported helper object.
* Use new FallbackCompositionState API in BeforeInputEventPlugin
* Implement event-specific pooling in SyntheticEvent
* Remove PooledClass from TopLevelCallbackBookKeeping
* Update results.json
* Add pooled event test fixtures (#1)
* Fix fixture lint
* Use single entry point for SSR via browser field
* Add server.browser entry point and smoke tests
* Tweak bundle naming
* Fix import
* Re-record
* Fix the robot nits
* Add resetModules for some extra isolation
This avoids strict mode conflicts for certain browsers wrt functions being defined within an if-block.
Also re-added the if-DEV condition for the ReactNative renderer since it was removed for this reason.
FB bundles wrap warning() calls in __DEV__
Split dev-mode transforms into separate parts:
1) umd+cjs+fb: Wrap warning calls with process.env checks
2) umd+cjs: Replace error messages with minified codes
Also updated transforms to use __DEV__ since it transforms to smaller code after stripEnvVariables is run.
Also renamed 'scripts/error-codes/dev-expression-with-codes.js' -> 'scripts/error-codes/replace-invariant-error-codes.js'
The critical semantics are resilient to browser flakiness, so we don't
need this feature test.
Also added comments explaining how invokeGuardedCallback dev works.
invokeGuardedCallback is a function we use in place of try-catch
statement. It accepts a function, and if the function throws, it
captures the error. In production, the implementation is a normal try-
catch. In development, we swap out the prod implementation for a special
version designed to preserve "Pause on all exceptions" behavior of the
browser DevTools.
invokeGuardedCallbackDev works by dispatching an event to a dummy DOM
node and calling the provided function inside a handler for that event.
We also attach an error event handler to the window object. If the
function throws, the global event handler is called and we can access
the error.
The global event handler is added and removed right before and after the
fake event is dispatched. But if invokeGuardedCallbackDev is nested --
that is, if it's invoked inside the body of another
invokeGuardedCallbackDev -- multiple error event handlers will attached
simultaneously. We only want the handler that corresponds to the deepest
level to handle the error. So we keep track of a depth counter, and
within the event handler, we only handle the error if the current depth
matches the depth at the time the function was invoked.
The problem that we discovered, and that this PR fixes, is that the
depth counter is local to each renderer. So if you nest separate copies
of invokeGuardedCallback from separate renderers, each renderer will
have its own depth counter, and multiple error handlers will fire for a
single, nested error.
* Ran prettier over non-modified files to change them
* Fixed output of failing Prettier message to show invalid files
* Failing Prettier command now suggests 'yarn prettier-all'
* Support throwing null
In JavaScript, you can throw values of any type, not just errors. That
includes null. We currently rely on null checks to determine if a user-
provided function has thrown. This refactors our error handling code to
keep track of an explicit boolean flag instead.
* Add DOM fixture test case for break on exception behavior
* preventDefault error events during feature test
We call invokeGuardedCallbackDev at startup as part of a feature test.
But we don't want those errors to log to the console.
* Add throwing null test case
* Use ReactFeatureFlags instead of ReactDOMFeatureFlags
React ART uses this, too.
* Non-errors in error logger
If a non-error is thrown, we'll coerce the value to a string and use
that as the message.
* RFC Add warning for rendering into container that was updated manually
RFC because we still need to tidy this up and verify that all tests
pass.
**what is the change?:**
We want to warn when users render into a container which was manually
emptied or updated outside of React. This can lead to the cryptic error
about not being able to remove a node, or just lead to silent failures
of render. This warning should make things more clear.
Note that this covers the case where the contents of the root container
are manually updated, but does not cover the case where something was
manually updated deeper in the tree.
**why make this change?:**
To maintain parity and increase clarity before releasing v16.0 beta.
**test plan:**
`yarn test`
**issue:**

last item under the '16 beta' checklist.
* Add test and tweak check for rendering into manually updated container
STILL TODO: figure out how to skip this warning when the component
renders to a portal.
Unfortunately 'ReactPortal.isPortal(children)' returns false, even in
the failing test where we are rendering to a portal.
**what is the change?:**
- added a test for the case where we call 'ReactDOM.render' with a new
container, using a key or a different type, after the contents of the
first container were messed with outside of React. This case throws,
and now at least there will be an informative warning along with the
error.
- We updated the check to compare the parent of the 'hostInstance' to
the container; this seems less fragile
- tweaked some comments
**why make this change?:**
Continue improving this to make it more final.

* Skip warning in 'ReactDOMFiberEntry' when mounting to Comment node
**what is the change?:**
We have a warning for cases when the container doesn't match the parent
which we remembered the previously rendered content being rendered into.
We are skipping that warning when you render into a 'comment' node.
**why make this change?:**
Basically, if you render into a 'comment' node, then the parent of the
comment node is the container for your rendered content. We could check
for similarity there but rendering into a comment node seems like a
corner case and I'd rather skip the warning without knowing more about
what could happen in that case.

* Improve warning message, remove dedup check, and unmock console.error
**what is the change?:**
Various changes to get this closer to being finished;
- Improved warning message (thanks @spicyj!!!)
- Removed dedup check on warning
- Remove mocking of 'console.error' in portals test
**why make this change?:**
- warning message improvement: communicates better with users
- Remove dedup check: it wasn't important in this case
- Remove mocking of 'console.error'; we don't want to ignore an
inaccurate warning, even for an "unstable" feature.
**test plan:**
`yarn test` -> follow-up commits will fix the remaining tests
**issue:**
issue #8854
* Possible fix for issue of incorrect warning for portal re-render
**what is the change?:**
Add a property to a container which was rendered into using
`ReactDOM.unstable_createPortal`.
**why make this change?:**
We don't want to warn for mismatching container nodes in this case - the
user intentionally rendered into the portal container instead of the
original container.
concerns;
- will this affect React Native badly?
- will this add bloat to the portal code? seems small enough but not
sure.

* Fix logic for checking if the host instance container is a portal
**what is the change?:**
When focusing on fixing the warning to not check when we are using
portals, I missed checking for the existence of the host instance parent
before checking if it was a portal. This adds the missing null checks.
**why make this change?:**
To fix a bug that the previous commit introduced.

* Add 'unmountComponentAtNode' call in test for reconciling pre-rendered markup
**what is the change?:**
We have a test that verifies React can reconcile text from pre-rendered
mark-up. It tests React doing this for three strings and three empty
strings.
This adds a call to 'unmountComponentAtNode' between the two
expectations for strings and empty strings.
**why make this change?:**
We now warn when someone messes with the DOM inside of a node in such a
way that removes the React-rendered content. This test was doing that. I
can't think of a situation where this would happen with server-side
rendering without the need to call 'unmountComponentAtNode' before
inserting the server-side rendered content.
**test plan:**
`yarn test`
Only one more failing test, will fix that in the next commit.

* ran prettier
* remove unused variable
* run scripts/fiber/record-tests
* Fix type error and improve name of portal container flag
**NOTE:** I am still looking for a good place to move this flag
assignment to, or a better approach. This does some intermediate fixes.
**what is the change?:**
- fixed flow error by allowing optional flag on a DOMContainer that
indicates it was used as a portal container.
- renamed the flag to something which makes more sense
**why make this change?:**
- get Flow passing
- make this change make more sense
We are still not sure about adding this flag; a follow-up diff may move
it or take a different approach.
**test plan:**
`yarn test`
**issue:**
https://github.com/facebook/react/issues/8854
* Add flag to portalContainer on mount instead of in `createPortal`
**what is the change?:**
We add a flag to the container of a 'portal' in the 'commit work' phase
in Fiber. This is right before we call `appendChildToContainer`.
**why make this change?:**
- Sometimes people call `ReactDOM.render(... container)`, then manually
clear the content of the `container`, and then try to call another
`ReactDOM.render(... container)`.
- This leads to cryptic errors or silent failure because we hold a
reference to the node that was rendered the first time, and expect it
to still be inside the container.
- We added a warning for this issue in `renderSubtreeIntoContainer`, but
when a component renders something returned by
`ReactDOM.unstable_createPortal(<Component />, portalContainer);`,
then the child is inside the `portalContainer` and not the `container,
but that is valid and we want to skip warning in that case.
Inside `renderSubtreeIntoContainer` we don't have the info to determine
if a child was rendered into a `portalContainer` or a `container`, and
adding this flag lets us figure that out and skip the warning.
We originally added the flag in the call to
`ReactDOM.unstable_createPortal` but that seemed like a method that
should be "pure" and free of side-effects. This commit moves the
flag-adding to happen when we mount the portal component.

* Force an 'any' type for the `hostInstance.parentNode` in warning check
**what is the change?:**
This is awful. :(
I'm not sure how else to let Flow know that we expect that this might be
a sort of `DOMContainer` type and not just a normal `Node` type.
To at least make the type information clear we added a comment.
**why make this change?:**
To get `flow` passing. Looks like we have `any` types sprinkled
throughout this file. phooey. :(
**test plan:**
`yarn flow`
**issue:**

* Ignore portals in `DOMRenderer.findHostInstance`
**what is the change?:**
We want to ignore portals when firing a certain warning.
This allows us to get the host instance and ignore portals.
Also added a new snapshot recording while fixing things.
**why make this change?:**
Originally we had added a flag to the DOM node which was used for
rendering the portal, and then could notice and ignore children rendered
into those nodes.
However, it's better to just ignore portals in
`DOMRenderer.findHostInstance` because
- we will not ignore a non-portal second child with this approach
- we meant to ignore portals in this method anyway (according to a
'TODO' comment)
- this change only affects the DOM renderer, instead of changing code
which is shared with RN and other renderers
- we avoid adding unneeded expandos
**test plan:**
`yarn test`
**issue:**
https://github.com/facebook/react/issues/8854
* Ran prettier
* Remove error snapshot test
I think there is a bug where an empty snapshot is treated as an 'outdated snapshot'.
If I delete the obsolute snapshot, and run ReactDOMFiber-test.js it generates a new snapshot.
But then when I run the test with the newly generated snapshot, it says "1 obsolete snapshot found",
At some point I will file an issue with Jest. For now going to skip the snapshot generation for the error message in the new test.
* Remove expando that we were adding to portal container
**what is the change?:**
see title
**why make this change?:**
this is part of an old approach to detecting portals, and we have
instead added a check in the `findHostInstance` method to filter out
portals.
**test plan:**
`yarn test`
**issue:**
https://github.com/facebook/react/issues/8854
* Fork `findHostInstance` to make `findHostInstanceWithNoPortals`
**what is the change?:**
We need to get host instances, but filter out portals. There is not
currently a method for that.
**why make this change?:**
Rather than change the existing `findHostInstance` method, which would
affect the behavior of the public `findDOMNode` method, we are forking.

`yarn test`
