* Enable User Timing API integration with a feature flag
* Expose a way to toggle user timing flag in www
* Update ReactNativeCSFeatureFlags.js
* Update ReactFeatureFlags.js
* Fix dead code elimination for feature flags
Turning flags into named exports fixes dead code elimination.
This required some restructuring of how we verify that flag types match up. I used the Check<> trick combined with import typeof, as suggested by @calebmer.
For www, we can no longer re-export `require('ReactFeatureFlags')` directly, and instead destructure it. This means flags have to be known at init time. This is already the case so it's not a problem. In fact it may be better since it removes extra property access in tight paths.
For things that we *want* to be dynamic on www (currently, only performance flag) we can export a function to toggle it, and then put it on the secret exports. In fact this is better than just letting everyone mutate the flag at arbitrary times since we can provide, e.g., a ref counting interface to it.

This annotation is unnecessary because we already warn for bad event listener types.
* Record sizes
* Implement CS first take
This is using a pure JS API. This should probably switch to native hooks
at some later point but I'll start ironing out issues at this level first.
* Use async scheduling by default
The scheduled callback gets called immediately in render with infinite
time for now. Later this will be per root and abortable.
* Fix up the type signature of the ReactNativeCSType export
* Add escape hatch for special cased children
Working around the fact that we can't map arbitrary children slots. Just
the "children" prop.
* Readd providesModule for ReactNativeCSTypes
* Fix lint

* Remove hacks for Jest + Workspace integration
They were fixed by https://github.com/facebook/jest/pull/4761.

I changed them to absolute to work around a Jest bug.
The bug has been fixed so I can revert my past changes now.
* Added an automated test that would have caught the recent error code transform bug
* Renamed dev-expression-with-codes test to replace-invariant-error-codes
* Formatting nit
* Use relative paths in packages/react
* Use relative paths in packages/react-art
* Use relative paths in packages/react-cs
* Use relative paths in other packages
* Fix as many issues as I can
This uncovered an interesting problem where ./b from package/src/a would resolve to a different instantiation of package/src/b in Jest.
Either this is a showstopper or we can solve it by completely fobbidding remaining /src/.
* Fix all tests
It seems we can't use relative requires in tests anymore. Otherwise Jest becomes confused between real file and symlink.
https://github.com/facebook/jest/issues/3830
This seems bad... Except that we already *don't* want people to create tests that import individual source files.
All existing cases of us doing so are actually TODOs waiting to be fixed.
So perhaps this requirement isn't too bad because it makes bad code looks bad.
Of course, if we go with this, we'll have to lint against relative requires in tests.
It also makes moving things more painful.

Shouldn't affect correctness (they were ignored) but fixes DEV size regression.
* Record sizes
* Fix weird version in package.json
* Tweak bundle labels
* Get rid of output option by introducing react-dom/server.node
* Reconciler should depend on prop-types
* Update sizes last time
* Split performWork into renderRoot and commitRoot
It turns out that the scheduler is too coupled to how the DOM renderer
works. Specifically, the requestIdleCallback model, and how roots are
committed immediately after completing. Other renderers have different
constraints for when to yield and when to commit work.
We're moving towards a model where the scheduler only works on a single
root at a time, and the render phase and commit phase are split into
distinct entry points. This gives the renderer more control over when
roots are committed, coordinating multiple roots, deferring the commit
phase, batching updates, when to yield execution, and so on.
In this initial commit, I've left the renderers alone and only changed
the scheduler. Mostly, this involved extracting logic related to
multiple roots and moving it into its own section at the bottom of the
file. The idea is that this section can be lifted pretty much as-is
into the renderers. I'll do that next.
* Remove FiberRoot scheduleAt
Isn't actually used anywhere
* Make the root schedule a linked list again
Since this still lives inside the renderer, let's just use the
FiberRoot type. The FiberRoot concept will likely be lifted out
eventually, anyway.
* commitRoot should accept a HostRoot
This way it's less reliant on the alternate model
* Unify branches
* Remove dead branch
onUncaughtError is only called while we're working on a root.
* remainingWork -> remainingExpirationTime
I was wary of leaking NoWork but mixing numbers and null is worse so
let's just do it until we think of something better.
* Rename stuff
While testing some changes to RN, I noticed that the '--sync-fbsource' flag had been broken recently by things being moved around and the newly-added CS renderer. Fixed it up.
* react-dom/src/syntheticEvents => events, and put plugins into it
* Flatten react-dom/src/shared
* Split react-dom/src/client/utils into event/ and root client folder
Makes it clearer what is used by what.
* Strictly separate modules that can be imported by client and server
* shared/src -> shared
It's not a real package and doesn't even have package.json.
This will also make importing less weird if we drop Haste.
* Get rid of shared/utils
Moved event-specific into shared/event.
Moved rest to the root since distinction has always been pretty arbitrary.
* Fix references to old shared/src paths
* Move files and tests to more meaningful places
* Fix the build
Now that we import reconciler via react-reconciler, I needed to make a few tweaks.
* Update sizes
* Move @preventMunge directive to FB header
* Revert unintentional change
* Fix Flow coverage
I forgot to @flow-ify those files. This uncovered some issues.

* Include component stack in more places, including SSR
* Forbid including reconciler code into the server bundle
* Tighten up the Flow annotation
* Fix lint
* Gosh Prettier
* Only renderers should depend on reconciler code
* Remove react-art dependency on react-dom modules
They share ReactDOMFrameScheduling so I moved it to shared.
* Update build size
* [CS] Clone container instead of new root concept
The extra "root" concept is kind of unnecessary. Instead of having a
mutable container even in the persistent mode, I'll instead make the
container be immutable too and be cloned. Then the "commit" just becomes
swapping the previous container for the new one.
* Change the signature or persistence again
We may need to clone without any updates, e.g. when the children are changed.
Passing in the previous node is not enough to recycle since it won't have the
up-to-date props and children. It's really only useful to for allocation pooling.
* Implement persistent updates
This forks the update path for host fibers. For mutation mode we mark
them as having an effect. For persistence mode, we clone the stateNode with
new props/children.
Next I'll do HostRoot and HostPortal.
* Refine protocol into a complete and commit phase
finalizeContainerChildren will get called at the complete phase.
replaceContainer will get called at commit.
Also, drop the keepChildren flag. We'll never keep children as we'll never
update a container if none of the children has changed.
* Implement persistent updates of roots and portals
These are both "containers". Normally we rely on placement/deletion effects
to deal with insertions into the containers. In the persistent mode we need
to clone the container and append all the changed children to it.
I needed somewhere to store these new containers before they're committed
so I added another field.
* Commit persistent work at the end by swapping out the container
* Unify cloneOrRecycle
Originally I tried to make the recyclable instance nullable but Flow didn't
like that and it's kind of sketchy since the instance type might not be
nullable.
However, the real difference which one we call is depending on whether they
are equal. We can just offload that to the renderer. Most of them won't
need to know about this at all since they'll always clone or just create
new.
The ones that do know now have to be careful to compare them so they don't
reuse an existing instance but that's probably fine to simplify the
implementation and API.
* Add persistent noop renderer for testing
* Add basic persistent tree test
* Test bail out
This adds a test for bailouts. This revealed a subtle bug. We don't set the
return pointer when stepping into newly created fibers because there
can only be one. However, since I'm reusing this mechanism for persistent
updates, I'll need to set the return pointer because a bailed out tree
won't have the right return pointer.
* Test persistent text nodes
Found another bug.
* Add persistent portal test
This creates a bit of an unfortunate feature testing in the unmount
branch.
That's because we want to trigger nested host deletions in portals in the
mutation mode.
* Don't consider container when determining portal identity
Basically, we can't use the container to determine if we should keep
identity and update an existing portal instead of recreate it. Because
for persistent containers, there is no permanent identity.
This makes it kind of strange to even use portals in this mode. It's
probably more ideal to have another concept that has permanent identity
rather than trying to swap out containers.
* Clear portals when the portal is deleted
When a portal gets deleted we need to create a new empty container and
replace the current one with the empty one.
* Add renderer mode flags for dead code elimination
* Simplify ReactNoop fix
* Add new type to the host config for persistent configs
We need container to stay as the persistent identity of the root atom.
So that we can refer to portals over time.
Instead, I'll introduce a new type just to temporarily hold the children
of a container until they're ready to be committed into the permanent
container. Essentially, this is just a fancy array that is not an array
so that the host can choose data structure/allocation for it.
* Implement new hooks
Now containers are singletons and instead their children swap. That way
portals can use the container as part of their identity again.
* Update build size and error codes
* Address comment
* Move new files to new location
* Enable Yarn workspaces for packages/*
* Move src/isomorphic/* into packages/react/src/*
* Create index.js stubs for all packages in packages/*
This makes the test pass again, but breaks the build because npm/ folders aren't used yet.
I'm not sure if we'll keep this structure--I'll just keep working and fix the build after it settles down.
* Put FB entry point for react-dom into packages/*
* Move src/renderers/testing/* into packages/react-test-renderer/src/*
Note that this is currently broken because Jest ignores node_modules,
and so Yarn linking makes Jest skip React source when transforming.
* Remove src/node_modules
It is now unnecessary. Some tests fail though.
* Add a hacky workaround for Jest/Workspaces issue
Jest sees node_modules and thinks it's third party code.
This is a hacky way to teach Jest to still transform anything in node_modules/react*
if it resolves outside of node_modules (such as to our packages/*) folder.
I'm not very happy with this and we should revisit.
* Add a fake react-native package
* Move src/renderers/art/* into packages/react-art/src/*
* Move src/renderers/noop/* into packages/react-noop-renderer/src/*
* Move src/renderers/dom/* into packages/react-dom/src/*
* Move src/renderers/shared/fiber/* into packages/react-reconciler/src/*
* Move DOM/reconciler tests I previously forgot to move
* Move src/renderers/native-*/* into packages/react-native-*/src/*
* Move shared code into packages/shared
It's not super clear how to organize this properly yet.
* Add back files that somehow got lost
* Fix the build
* Prettier
* Add missing license headers
* Fix an issue that caused mocks to get included into build
* Update other references to src/
* Re-run Prettier
* Fix lint
* Fix weird Flow violation
I didn't change this file but Flow started complaining.
Caleb said this annotation was unnecessarily using $Abstract though so I removed it.
* Update sizes
* Fix stats script
* Fix packaging fixtures
Use file: instead of NODE_PATH since NODE_PATH.
NODE_PATH trick only worked because we had no react/react-dom in root node_modules, but now we do.
file: dependency only works as I expect in Yarn, so I moved the packaging fixtures to use Yarn and committed lockfiles.
Verified that the page shows up.
* Fix art fixture
* Fix reconciler fixture
* Fix SSR fixture
* Rename native packages
* Inline getTestDocument into test cases
* Remove mention of mock file we do not use
* Remove unused configuration entries
* Move eslint-rules package into the scripts/ folder
* Deterministic updates
High priority updates typically require less work to render than
low priority ones. It's beneficial to flush those first, in their own
batch, before working on more expensive low priority ones. We do this
even if a high priority is scheduled after a low priority one.
However, we don't want this reordering of updates to affect the terminal
state. State should be deterministic: once all work has been flushed,
the final state should be the same regardless of how they were
scheduled.
To get both properties, we store updates on the queue in insertion
order instead of priority order (always append). Then, when processing
the queue, we skip over updates with insufficient priority. Instead of
removing updates from the queue right after processing them, we only
remove them if there are no unprocessed updates before it in the list.
This means that updates may be processed more than once.
As a bonus, the new implementation is simpler and requires less code.
* Fix ceiling function
Mixed up the operators.
* Remove addUpdate, addReplaceState, et al
These functions don't really do anything. Simpler to use a single
insertUpdateIntoFiber function.
Also splits scheduleUpdate into two functions:
- scheduleWork traverses a fiber's ancestor path and updates their
expiration times.
- scheduleUpdate inserts an update into a fiber's update queue, then
calls scheduleWork.
* Remove getExpirationTime
The last remaining use for getExpirationTime was for top-level async
updates. I moved that check to scheduleUpdate instead.
* Move UpdateQueue insertions back to class module
Moves UpdateQueue related functions out of the scheduler and back into
the class component module. It's a bit awkward that now we need to pass
around createUpdateExpirationForFiber, too. But we can still do without
addUpdate, replaceUpdate, et al.
* Store callbacks as an array of Updates
Simpler this way.
Also moves commitCallbacks back to UpdateQueue module.
* beginUpdateQueue -> processUpdateQueue
* Updates should never have an expiration of NoWork
* Rename expiration related functions
* Fix update queue Flow types
Gets rid of an unneccessary null check
* CS renderer
Because we didn't have enough RN experiments. I want to add one more.
* Split out hydration from the host config object
This makes it easier to do feature detection on the configuration.
* Move mutation host config to separate optional object
* Refs and life-cycles should happen even in immutable mode
* Unmount components even in non-mutation mode
This is the same as committing deletions but instead of finding host
components to delete, it only invokes componentWillUnmount and detaching
of refs.
* Add persistent updates API
This mode will use a clone based API instead of mutating host instances.
Needs implementation still.
It's awkward that there can be more than one child inserted into the root.
So we need a new API to create a "root" instance so that we can update it
atomically. Alternatively we could keep the mutable API for containers
and assume that most use cases would only have a single root.

* Inject the right event emitter
Previously this was injecting the ReactNativeEventEmitter even though
we want the ReactNativeRTEventEmitter.
RCTEventEmitter is also just an abstraction around BatchedBridge that
registers a single name. We can't register more than one with it. Removed
that abstraction for now so we don't have to add it back into the RN repo.
* Unify appendChildToDetachedParent and appendChild, separate root
Merge appendChildToDetachedParent and appendChild. We don't need the distinction.
We do however need a separate notion for the root container.
Calling this `appendChildToContext` since Context has a meaning here.
* Add a simple shallow comparison so that we don't send updates for equal props
This still sends all props if any differs. Not sure we'll want that but I
think so.
* Add BatchedBridge to bundle externals
* Lint
* Deleted docs folder
* Deleted www folder
* Remove Netlify website build command
* Removed refs to docs and www from ESlint config
* Removed refs to www/docs from Flow config
* Removed unnecessary .gitignore config
* Updated license check to remove refs to docs
* Removed gh-pages specific portions of Circle build scripts
There may be more that we can remove (eg set_up_github_keys.sh) but I'm not positive
* Removed docs specific license
This is an experimental new protocol for some experiments we want to play
with. To make that easier, I'm just going to fork it.
This experiment won't use the event system so I by-pass it and just invoke
functions on the props object for now.
I also fork the UIManager into a new RTManager.
Adds a new docs website, built with Gatsby JS, to replace the old Jekyll site. Source code for the new site lives in /www (although markdown and YML data still comes from the legacy /docs folder).
Changes to either markdown or website source code can be previewed on Netlify. The react-js bot should automatically add comments to each PR with preview links. (This preview is generated by running the newly-added yarn build:docs command in the root package.json.)
The majority of the changes in this PR are contained within the new /www directory. However some minor modifications have been made to existing content in the /docs directory:
* Modified frontmatter author block to always be an array
* Small markdown formatting tweaks
Did find and replace in TextMate.

* ReactNativeBridgeEventPlugin supports lazily-registered event types
This accompanies changes on the native side to now specify which event types each view manager supports as part of its view config. Ultimately the goal is to lazily initialize view managers on the native side as well.
* Bubbling and direct attributes are optional on view config
This should help ease transition for pre-existing JS-only components.

NaN. To compare that we also need to switch to Object.is.
* 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:**

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.

* 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

* 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.

* 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. :(

* 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.

* 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.

Alternative to using the static class property unstable_asyncUpdates.
Everything inside <AsyncComponent /> has async updates by default. You
can also extend it like PureComponent or Component.
* Disable Fiber specific test run in CI
This disables the comparison against previously recorded test. Instead,
we'll rely on jest failures to fail tests.
* Extract jest config into two separate projects for Fiber and Stack
Allows us to run both in the same jest run. The setupMocks file is forked into
specific environment configuration for each project. This replaces the
environment variable.
I used copy pasta here to make it clear. We can abstract this later. It's clear
to me that simply extracting shared stuff is not the best way to abstract this.
setupMocks for example didn't need all the code in both branches.
I think that some of the stuff that is shared such as error message extracting
etc. should probably be lifted out into a stand-alone jest project instead of
being shared.
* Fix class equivalence test
There's a behavior change when projects are used which makes
setupTestFrameworkScriptFile not override the normal config.
This test should probably just move to a separate CI script or something
less hacky.
* Only run Fiber tests with scripts/fiber/record-tests
* Move input valueTracker to DOM nodes
This moves the storage of the input value tracker to the DOM node
instead of the wrapperState. This makes it easier to support both Stack
and Fiber without out a lot of ugly type casting and logic branches.

* Make CSSPropertyOperations client-only
I forked createMarkupForStyles() into ReactDOMComponent and ReactPartialRenderer. Duplication is fine because one of them will soon be gone (guess which one!)
The warnInvalidStyle helper is used by both server and client, unlike other client-only stuff in CSSPropertyOperations, so I moved it to a separately module used in both.
* Record server bundle size
* Add an early exit to validation
* Clarify what is being duplicated
* Upgrade jest to 20.1.0-delta.1
This includes multi-project support.
* Use isSpy polyfill that is not available in jest 20
* Remove use of jasmine.createSpyObj
We don't really need this and it's not in jest 20.
* Upgrade record-tests script to use the new jest 20 APIs
* Use performFailedUnitOfWork
instead of beginFailedWork and completeUnitOfWork separately. Also, we
unwind the context stack *before* beginning work again.
* Only use error loop directly after a commit
We have a special, forked version of work loop that checks if a fiber is
in a failed state (needs to be unmounted). This is only relevant right
after a commit -- begin phase errors are handled differently, by
unwinding the stack.
Also renamed findNextUnitOfWork to resetNextUnitOfWork and made it a
void function to signal that it's impure.
* Reset nextUnitOfWork after every commit
* Include the error boundary when unwinding a failed subtree
Also added a warning to the error boundary to show that it failed.
* Push context providers in beginFailedWork to avoid push/pop mismatch
Added a test that demonstrates how an error boundary that is also a
context provider could pop its context too many times if you neglect
to push it in beginFailedWork. This happens because we've already
popped the context once in unwindContext.
The solution is a code smell. I don't like how we push/pop context in
so many places. Shouldn't they all happen in the same location?
* Refactor work loop
- Optimizes the normal, non-error path by reducing the number of checks
needed to begin performing work.
- Prevents control flow from oscillating between fast normal loop and
slower error loop.
* Improve context unwinding test
Tests that we correctly unwind an error boundary that is also a
context provider.
* Triangle tester should assert the tree is consistent after every action
...not just at the end.
* Better implementation of infinite loop error
Infinite loops should only be possible if a while loop never terminates.
Now that we've refactored to avoid oscillation between different
work loops, we can count updates local to each loop.
The two loops that could infinite loop are the sync work loop and the
loop that surrounds the body of the render phase catch block. The
async loop could also fall into an infinite loop if the deadline never
terminates, but we'll assume that it always eventually does.
This change also creates better error stack traces because the error is
thrown from inside the first setState that exceeds the limit.
Added a test case for an error boundary whose parent remounts it
on recovery.
* Use invokeGuardedCallback in DEV
* Add a regression test that passes in Stack but fails in Fiber
The failure happens because trackValueOnNode() can exit early if it detects an existing descriptor on node, or if it sees a "broken" Safari descriptor (which is how we encountered this bug in the wild).
As a result, the tracker field was not set, and subsequent updateValueIfChanged() call went into the branch that initializes the tracker lazily. That branch has a bug in Fiber mode where it passes the wrong type.
We did not see this issue before because that branch is relatively hard to hit (you have to either run it in Safari or define a custom DOM value descriptor which is what I did in the test).
In the future, we will likely remove the lazy branch altogether since if we bailed out of setting up the tracker once, we will likely bail out every time. But for now I'm just focused on a minimal fix to unbreak master.
* Fix updateValueIfChanged() lazy path to work with DOM argument
* Slightly reorder lines for clarity and record tests
* Also test the change event code path
This makes it go through the Fiber argument code path.
* Extract the top element frame from ReactDebugCurrentFrame
This is part of a larger refactor to decouple stack addendums. All
renderers have their own way of getting the stack of the currently
executing components.
There is one special case in Element Validator that adds an additional line
for the element being validated. This commit moves that special case in
into the validator.
There is another case where it looked like this was used in shallow
renderer but this is actually something different. It is part of the
component stack. It just happens to be that shallow renderer has a simpler
implementation of the component stack that just happens to be a single
element.
This will let us decouple the implementation to get a stack from
ReactDebugCurrentFrame and put that in each renderer.
* Stop using ReactComponentTreeHook for Fiber
Currently we fall back to ReactCurrentOwner in ReactComponentTreeHook for
stack addendums. We shouldn't need to because we should use
ReactDebugCurrrentFiber.
Ensure we always set both ReactDebugCurrentFiber and ReactDebugCurrentFrame
so that we can rely on these for all stacks.
* Make ReactDebugCurrentFrame implementation independent
Introduced ReactDebugCurrentStack for the Stack renderer which does the
same thing as ReactDebugCurrentFiber.
ReactDebugCurrentFrame no longer keeps track of the current fiber/debug id.
That's handled by the individual renderers.
Instead, it is now used to keep track of the current *implementation* of
the current stack frame. That way it is decoupled from the specifics of
the renderers. There can be multiple renderers in a context. What matters
is which one is currently executing a debuggable context (such as a render
function).
* Add debug frames to ReactPartialRenderer (ssr)
Basic functionality.
* Add shared modules to shallow renderer
This is now needed because we share describeComponentFrame.
* Limit the number of nested synchronous updates
In Stack, an infinite update loop would result in a stack overflow. This
gives the same behavior to Fiber.
Conceptually, I think this check belongs in findNextUnitOfWork, since
that is what we call right before starting a new stack. I've put it
in scheduleUpdate for now so I have access to the component that
triggered the nested update. But we could track that explicitly instead.
I've chosen 1000 as the limit rather arbitrarily. Most legit use cases
should really have a much smaller limit, but a smaller limit could break
existing code. For now I'm only concerned with preventing an infinite
loop. We could add a warning that fires at the smaller limit.
* Move check to findNextUnitOfWork
Including the name of the component in the message probably isn't
necessary. The JS stack will include either componentDidUpdate or
componentWillUpdate. And the component that's updating won't
necessarily be the component whose lifecycle triggered it.
So let's move the infinite loop check to findNextUnitWork as I
originally wanted to.
* WIP Improve error message thrown in Fiber with multiple copies of React
**what is the change?:**
Adding an 'invariant' with detailed error message for the problem that
occurs when you load two copies of React with the Fiber reconciler.
WIP:
- Is there any other likely cause for this error besides two copies of
React?
- How can we make the message more clear?
Still TODO:
- Write a unit test
- Write a documentation page and create the link to the page, similar
to https://facebook.github.io/react/warnings/refs-must-have-owner.html
It would also be nice to have a page with instructions on how to fix
common cases of accidental double-loading of React, but we can open a
separate issue on that and let the community do it.
**why make this change?:**
This error comes up relatively often and we want to make things clear
when it happens in v16.0+
**test plan:**
WIP
**issue:**
Fixes#9962
* Add improved warning and docs for 'refs must have owner' in Fiber
**what is the change?:**
- Added warning in the place where this error is thrown in Fiber, to
get parity with older versions of React.
- Updated docs to mention new error message as well as old one.
I started to write a new docs page for the new error, and realized the
content was the same as the old one. So then I just updated the existing
error page.
**why make this change?:**
We want to avoid confusion when this error is thrown from React v16.
**test plan:**
- manually inspected docs page
- manually tested in a CRA to trigger the error message
(Flarnie will insert screenshots)

* Add test for the informative warning around multiple react copies
@gaearon debugged the test for this and now it works!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :)
**what is the change?:**
We now test for the warning that the previous commits add in Fiber, and
also test for the old warning in the stack reconciler.
**why make this change?:**
This is an especially important warning, and we want to know that it
will fire correctly.

**what is the change?:**
refactor test for 'multiple copies of React' to be simpler and remove
some copypasta
* run prettier
* Fix conditionals in 'multiple copies of react' test
**what is the change?:**
When moving the 'fiber' and 'non-fiber' conditions from two assertions
into one, we copy pasted the wrong message into the 'fiber' condition.
This wasn't caught because we were using an outdated name for the
'fiber' constant when running the tests locally with fiber enabled.
This fixes the copy-paste error and we now are actually running the
tests with fiber enabled locally.

react-native-web and react-primitives currently access a few internals
for shimming DOM events into native ones. Changes in react@16 packaging
hide these internals completely. This change adds a submodule to react-dom,
unstable-native-dependencies that includes the necessary modules to
continue enabling that method of dom-native event injection.
* Update ResponderEventPlugin to use "public" interfaces for test
In order to get some sort of smoke testing on
react-dom-unstable-native-dependencies, update ResponderEventPlugin-test
to use the "public" interfaces provided by react-dom and the new
react-dom/unstable-native dependencies
Also adds the missing references in package.json as well as missing
files required for unittests to do imports correctrly
Also exports injectComponentTree() which is required for the unittests
to re-set the shared component state between runs.
* Tweak bundle comment
* Bundle content updates from exporting injectComponentTree
* Added FB_DEV, FB_PROD to bundle types
* Run yarn prettier for -unstable-native-dependencies updates
* Add failing test to show that shallow test renderer doesn't call setState's callback arg
* Record tests
* Fix shallow renderer's setState/replaceState/forceUpdate to execute any callbacks passed. (#10089)
* Ensure shallow renderer callbacks are called with the correct binding.
To make sure we don't reset the priority of a down-prioritized fiber,
we compare the priority we're currently rendering at to the fiber's
work priority. If the work priority is lower, then we know not to reset
the work priority.
* Warn for text content
* Warn for different attributes/properties values
Warns if there are unknown extra attributes in the hydrated node.
It also tries to compare the existing property or attribute against the
expected value. It does this by reading the property and comparing it to
the prop. Except it's not that simple because multiple prop values can
yield the same output. For this we pass an extra expected value that is
a hint as to which one was used. This is a bit weird but I'm not sure the
alternatives were much better.
* Warn when there is an insertion or deletion during hydration
This warns if there is ever an insertion or deletion due to hydration
failing to find a match.
Currently we can't warn for insertions required into the root because
that's how we do all non-hydrating renders atm. Left a todo.
This strategy is a bit unfortunate that it leads to so much plumbing code.
And we have to add three extra methods to the HostConfig that are only used
in DEV and not for anything else. I don't really have a better idea.
* Don't try to delete children of a textarea
Textareas are special cases. The initial mount inserts children
as the default value, but we should leave that untouched. This is the same
as the special case where we set text content of children so I'll use that
mechanism.
* Change expected format for text differences
In Stack this is presented as HTML which needs to have normalized escaping
rules. In Fiber it is currently not presented as HTML but a raw string
so we don't escape it.
* Unmount component in between tests
In Fiber, the second warning isn't issued because it's considered an update
not a new initial render and we don't fire the warning for those.
* Change expectation of white space text behavior in Fiber
In Fiber we don't expect empty strings to be different from rendering null.
In fact, in a follow up I plan on formalizing this by never creating text
Fibers for empty strings.
* Warn for different dangerouslySetInnerHTML
We can't just compare the raw innerHTML value because it will have been
normalized. Instead, we'll create another element, set its innerHTML and
read it back.
Since there can be custom elements registered with this document, we want
to avoid any side-effects they might cause. So I do this in a fresh new
document.
I'm not sure how this would affect controlled components and other stuff
that could have changed after runtime. I think for those cases maybe we
just need a general way of opting out of the diff.
* Warn if unmounting a non-container
* Warn if the 2nd+ child is a "root" element but not first
This triggers our non-reuse mode. This is covered by ReactMount already but
the test doesn't pass yet without also landing #10026.
This covers up errors that are thrown in Fiber, because callback gets
fired *and* an error is thrown. Created a follow up #10049 to reevaluate
these semantics.
# Conflicts:
# scripts/fiber/tests-passing-except-dev.txt

There's no advantage to scheduling updates with animation priority
versus scheduling sync work inside requestAnimationCallback. So we can
remove all the animation-specific code. Now there's only one type of
callback.
Allows us to make assertions on the values that are yielded when
performing work. In our existing tests, we do this manually by pushing
into an array.
ReactNoop.flushThrough extends this concept. It accepts an array of
expected values and flushes until those values are yielded.

* Fix Flow
* Add check for string and null 'rootElement' in ReactDOMFiber
**what is the change?:**
Before we call 'rootElement.getAttribute' we check that the method is
defined.
**why make this change?:**
There is an internal use case I found where 'rootElement' is a string
and null at different points as the page is rendered.
It looks like this method was added as part of support for re-hydration
of server-side rendered content. I can't imagine we would want to reuse
content if the rootnode is a string or null. Not sure if we want an
earlier check that it's an element before this point.
**test plan:**
`yarn test`
and I manually tested this fix in the internal case where it was
breaking
* Add test and improve check for non-element rootElement
**what is the change?:**
We use the nodeType to check that we have the correct type of
rootElement, and we added a unit test.
**why make this change?:**
Improve this solution to the problem.
**test plan:**
`yarn test`
* run ./scripts/fiber/record-tests
* Don't hydrate any properties other than event listeners and text content
This strategy assumes that the rendered HTML is correct if the tree lines
up. Therefore we don't diff any attributes of the rendered HTML.
However, as a precaution I ensure that textContent *is* updated. This
ensures that if something goes wrong with keys lining up etc. at least
there is some feedback that the event handlers might not line up. With
what you expect. This might not be what you want e.g. for date formatting
where it can different between server and client.
It is expected that content will line up. To ensure that I will in a follow
up ensure that the warning is issued if it doesn't line up so that in
development this can be addressed.
The text content updates are now moved to the commit phase so if the tree
is asynchronously hydrated it doesn't start partially swapping out. I use
the regular update side-effect with payload if the content doesn't match up.
Since we no longer guarantee that attributes is correct I changed the
bad mark up SSR integration tests to only assert on the textContent
instead.
* Hydrate text node if possible
Currently we're never matching text nodes so we need to properly branch.
* Tweak syntax in rollup build script
@bvaughn and I already discussed this.
**test plan:**
`yarn build`
* Remove JSDoc comments
**what is the change?:**
removing some comments
**why make this change?:**
The code is basically self explanatory and these comments could get out
of sync.
**test plan:**
Visual inspection, `yarn build` and `yarn test`
**issue:**
https://github.com/facebook/react/issues/9398
According to #9836 we're intentionally chosing to not support this until
we have better proof of this being a big need. E.g. to protect against
extensions. In a way that it's not better to push extensions to be fixed.
This was mostly used for timing of initial mounts. However, we haven't
implemented that in Fiber and yet nobody has complained despite running
without it. Further more the update tracks any update within the tree,
not just updates to the props of the top level. This is much less useful
due to the variation.
I could make this track initial mounts too but it's a bit awkward so I'd
rather just delete it if possible. We can run the full profiling mode if
we want more coverage.
This is a follow-up on
https://github.com/facebook/react/pull/9584#discussion_r115642293. There
is no need to assign the value property of an input if the value
property of the React component changes types, but stringifies to the
same value. For example:
```javascript
DOM.render(<input value="true" />, el)
DOM.render(<input value={true} />, el)
```
In this case, the assignment to `input.value` will always be
cast to the string "true". There is no need to perform this
assignment. Particularly when we already cast the value to a string
later:
```javascript
// Cast `value` to a string to ensure the value is set correctly. While
// browsers typically do this as necessary, jsdom doesn't.
node.value = '' + value;
```
**what is the change?:**
- Add two more special cases for 'lowPriorityWarning' in 'modules.js',
treating it the same as 'ReactCurrentOwner'.
**why make this change?:**
Without this, the build was including 'lowPriorityWarning' seemingly both as an external module and as part of the bundle.
**test plan:**
Ran `yarn build` and inspected the `React-dev` build. `lowPriorityWarning` did not get bundled in this time.
**issue:**
None yet - @gaearon flagged this for me directly.
* Add back caught error and other checks to 'lowPriorityWarning'
**what is the change?:**
This change makes 'lowPriorityWarning' an exact copy of 'warning.js' from
e66ba20ad5/packages/fbjs/src/__forks__/warning.js
where before we had skipped some checks from that module.
- Adds an error which we catch, in order to let people find the error and resulting stack trace when using devtools with 'pause on caught errors' checked.
- Adds check that 'format' argument is passed
**why make this change?:**
- To maintain a closer fork to 'warning.js'
- To allow easier debugging using 'pause on caught errors'
- To validate inputs to 'lowPriorityWarning'
**test plan:**
`yarn test`
**issue:**
* Update 'print-warnings' script to include 'lowPriorityWarning' output
**what is the change?:**
We print the logs from 'lowPriorityWarning' as well as 'warning' from the 'print-warnings' script.
NOTE: This PR is branching off of https://github.com/facebook/react/pull/9754
**why make this change?:**
We want to use the same process of white/blacklisting warnings with 'lowPriorityWarning' that we do with 'warning'.
**test plan:**
This is not super easy to test unless we are doing a sync with FB afaik. I plan on running a sync in the next few days, or next week at latest, for the sake of not landing big things on a Friday. That will be the actual test of this.
**issue:**
https://github.com/facebook/react/issues/9398
* Don't double validate the DOM container
The warnings need to check a valid container but that should happen in
unstable_renderSubtreeIntoContainer too so might as well move it in.
* Hydrating DOM
Hydrates a server-rendered DOM tree by traversing it and connecting up the nodes if they match. Attributes are not diffed. They're assumed to be accurate on matching nodes.
* Remove meta data filtering from test
Because the current server renderer includes the meta data, it remains in a revived tree.
* Annotate because Flow
* Don't track insertion effects if we're going to hydrate
During initial mount, we should not track Placement
* Fix up test cases to ignore errors that we no longer throw
TODO make these warnings instead.
* Correctly track hydration state inside a newly inserted tree
When we don't match the first hydration node, we'll do an insertion.
Currently we keep the next hydratable sibling so that we know where to
pick up once we're done with the insertion. Unfortunately this makes the
nodes inside the insertion think that there's a node to hydrate.
I used to check for the direct parent but that doesn't work on nested host components.
We need to instead keep track of that we're in an hydration context but
we're not currently hydrating. Once we pop passed the inserted node can
we resume hydrating.
* Hacky fix to isMounted
isMounted checks whether a component is inside a Placement. During
hydration we ideally don't do any Placements if hydration matches the tree.
To work around this I use the Placement flag on the root, which isn't used
for anything else. But only temporarily while we're hydrating. Then reset
it before committing.
* Record tests
* Comments
Since stripEnvVariables was used to replace __DEV__ references, I assumed it (and other plugins) we run before requires statements were processed. Obviously I was wrong 😬 and as a result, the RN Stack and Fiber builds were way too large. This is an attempt to mimic the approach taken with DOM renderer and stub out modules that we explicitly don't want to include.
The alternative to this would have been to fork findNodeHandle, NativeMethodsMixin, ReactNativeBaseComponent, etc. and essentially avoid using the feature flag. That didn't seem tenable. The previous injection approach also doesn't work here because the circular references it resulted in caused Rollup to choke when creating the modules.
This regressed with the recent addition of RN_* bundles. I was accidentally stripping comments from FB_PROD when I meant to do the opposite. This corrects that mistake.
No significant bundle size change occurs when re-running this build against the version prior to the RN_* bundles.
* Split ReactNativeFiber into separate ReactNativeFiberRenderer module
Hopefully this is sufficient to work around Rollup circular dependency problems. (To be seen in subsequent commits...)
* Split findNodeHandle into findNodeHandleFiber + findNodeHandleStack
This allowed me to remove the ReactNative -> findNodeHandle injections, which should in turn allow me to require a fully-functional findNodeHandle without going through ReactNative. This will hopefully allow ReactNativeBaseomponent to avoid a circular dependency.
* Un-forked findNodeHandle in favor of just inlining the findNode function impl
* takeSnapshot no longer requires/depends-on ReactNative for findNodeHandle
Instead it uses the new, renderer-specific wrappers (eg findNodeHandleFiberWrapper and findNodeHandleStackWrapper) to ensure the returned value is numeric (or null). This avoids a circular dependency that would trip up Rollup.
* NativeMethodsMixin requires findNodeHandler wrapper(s) directly rather than ReactNative
This works around a potential circular dependency that would break the Rollup build
* Add RN_* build targets to hash-finle-name check
* Strip @providesModule annotations from headers for RN_* builds
* Added process.env.REACT_NATIVE_USE_FIBER to ReactNativeFeatureFlags
This is kind of a hacky solution, but it is temporary. It works around the fact that ReactNativeFeatureFlag values need to be set at build time in order to avoid a mismatch between runtime flag values. DOM avoids the need to do this by using injection but Native is not able to use this same approach due to circular dependency issues.
* Moved a couple of SECRET exports to dev-only. Removed SyntheticEvent and PooledClass from SECRET exports. Converted Rollup helper function to use named params.
* Split NativeMethodsMixins interface and object-type
* Add @noflow header to flat-bundle template to avoid triggering Flow problems
When Flow tries to infer such a large file, it consumes massive amounts of CPU/RAM and can often lead to programs crashing. It is better for such large files to use .flow.js types instead.
* NativeMethodsMixin and ReactNativeFiberHostComponent now share the same Flow type
* Collocated (externally exposed) ReactTypes and ReactNativeTypes into single files to be synced to fbsource. ReactNativeFiber and ReactNativeStack use ReactNativeType Flow type
* Build script syncs RN types and PooledClass automatically
* Added optional sync-RN step to Rollup build script
* Added results.json for new RN bundles
* Add back caught error and other checks to 'lowPriorityWarning'
**what is the change?:**
This change makes 'lowPriorityWarning' an exact copy of 'warning.js' from
e66ba20ad5/packages/fbjs/src/__forks__/warning.js
where before we had skipped some checks from that module.
- Adds an error which we catch, in order to let people find the error and resulting stack trace when using devtools with 'pause on caught errors' checked.
- Adds check that 'format' argument is passed
**why make this change?:**
- To maintain a closer fork to 'warning.js'

- To validate inputs to 'lowPriorityWarning'
**test plan:**
`yarn test`
**issue:**
* Update results.json
* Run prettier
* Initial regeneration of results.json
**what is the change?:**
We ran `yarn build` and updated the perf. stats record.
**why make this change?:**
Some commits have landed without updating this. By getting an initial update, I can run the build script again after my changes and see any size regressions.
* Downgrade deprecation warnings from errors to warnings
**what is the change?:**
Swapping out `warning` module for a fork that uses `console.warn`.
It looks like we were using the `warning` module for deprecation notices, *but* there is also a 'deprecated' module designed specifically for deprecation notices.
However, we could not find any place that it was currently used.
Since React's build process is not 100% clear to me, I assume it could still be used somewhere by something and just updated it along with other deprecation notices.
We might consider a follow-up diff that does some clean up here;
- remove 'deprecated' module if it's unused, OR
- use 'deprecated' module for all our current deprecation warnings
**why make this change?:**
- We have had complaints about noisy warnings, in particular after introducing new deprecations
- They potentially cause CI failures
- Deprecations are not really time-sensitive, can ship without breaking your app, etc.

**test plan:**
`npm run test`
and unit tests for the new modules
and manual testing (WIP)
**issue:**
https://github.com/facebook/react/issues/9395
* Add 'lowPriorityWarning' to ReactExternals
**what is the change?:**
We won't bundle 'lowPriorityWarning' with the rest of React when building for Facebook.
NOTE: A parallel commit will introduce an internal implementation of 'lowPriorityWarning' in Facebook's codebase, to compensate. Will post a comment with the diff number once that is up.
**why make this change?:**
So that the sync between github and Facebook can go more smoothly!
**test plan:**
We will see when I run the sync! But this is a reasonable first step imo.
**issue:**
https://github.com/facebook/react/issues/9398
* Make state mutations an error, not low-pri warning
**what is the change?:**
Even though this is a "deprecation" warning, we still want to use 'console.error' for it.
**why make this change?:**
- It's not likely to come up now, hopefully, because this warning has been present for some time
- This will cause real issues in production if ignored
**test plan:**
`yarn test` - we did fix one test which failed bc of this change
**issue:**
https://github.com/facebook/react/issues/9398
* Fix test of assigning to this.state that was only passing in fiber
**what is the change?:**
updated a unit test for assigning directly to state; it once again raises an error and not a warning.
**why make this change?:**
So that tests pass
**test plan:**
REACT_DOM_JEST_USE_FIBER=1 yarn run test
**issue:**
* Update results.json
* Adjust some expectations of the server markup format of Fiber
Currently this case is using the stack renderer.
* Ensure debug hooks are injected into the Stack server renderer
In our tests this normally happens because ReactDOM.js injects them into
the shared module, but when Fiber is enabled or this is its own flat
bundle, that doesn't happen.
* Add package builds for new server renderer and enable tests
ReactServer -> ReactDOMServerStream
This file is going to be the replacement for ReactDOMServer.
I mock ReactDOMServer and user ReactDOMServerStream when we have
the fiber flag enabled. I'm now also enabling this as the default for
distributions builds (react-dom/server on npm and
react-dom-server.production.min.js as umd bundle).
I'm using traverseStackChildren instead of traverseAllChildren because
traverseAllChildren is now only in the isomorphic package and we don't
want to build all of that that into the server package.
I also have to require lower case react for the builds to work.
* Server Rendering initial commit
Originally authored by spicyj, tweakes to rebase it and make it run by tomocchino.
Adding ReactDOMServerRendering and a createTagMarkup utility function which will be used in it.
* Fix build system, add shortcut scripts
* Make more ReactServerRendering-test unit tests pass
* Make ReactServerRendering-test pass with copious help from Ben
This is pretty hacky and I just inlined everything, but at least I sort of understand how it works now, and all of the tests are passing. There are also only 68 tests failing in the integration test suite.
* remove some unnecessary cruft
* Run prettier on ReactDOMServerRendering.js
* Fix more unit tests with Ben
* Add support for input and textarea by copy pasting a bunch of code from ReactDOMInput/ReactDOMTextarea
* Fix context unit tests with more copy paste :)
* progress on select
* Holy shit, 100% of ReactDOMServerIntegration tests are passing
* Checkpoint to fix some of the ReactDOMComponent-test tests
* Fix missing checkPropTypes
* Fix some unit tests in ReactDOMComponent-test
* Run prettier on everything, thanks Ben
* get rid of ssr tests that are looking for component file names
* add assertValidProps check
* rename flattenChildren to flattenOptionChildren per Ben
* Fix all the lint crap
* Move things around in the file and turn ReactDOMServerRenderer into a class
* remove changes I added to package.json
* remove separate createOpenTagMarkup file for now since everything should be copy pasted into a single file
* re-record Fiber tests
* Revert ReactDOMServer.js and the fiber tests per Sebastian
This also reverts the changes I made to ReactDOMComponent-test.js which removed the stack which is missing in the new server renderer"
* Rename files based on feedback
Moving src/renderers/dom/server/ReactDOMServerRendering.js to src/renderers/server/ReactServerRenderer.js and add src/renderers/server/ReactServer.js which makes this new codepath completely separate.
* Change throw to invariant, even though we probably need to remove this at some point
* fix prettier.. sigh
* Remove injectReactDOMEventListener from ReactBrowserEventEmitter
This PR removes the injection of ReactDOMEventListener from
ReactBrowserEventEmitter. Instead, the required initialization will
happen directly in ReactDOMInjection.
This injection was (probably) originally implemented for React Native
but never used, so we can clean it up.
* Mention how to see the full ouput of fiber tests
`ReactEventListener` is a DOM-specific module although the name suggests
otherwise. This change renames the module to the more specific
`ReactDOMEventListener`.
