* [React Native] Add tests to paper renderer for measure, measureLayout
* [React Native] measure calls will now call FabricUIManager
The Fabric renderer was previously calling the paper UIManager's measure calls and passing the react tag. This PR changes the renderer to now call FabricUIManager passing the node instead.
One of the parts of this that feels more controversial is making NativeMethodsMixin and ReactNative.NativeComponent warn when calling measureLayout in Fabric. As Seb and I decided in https://github.com/facebook/react/pull/15126, it doesn't make sense for a component created with one of these methods to require a native ref but not work the other way around. For example: a.measureLayout(b) might work but b.measureLayout(a) wouldn't. We figure we should keep these consistent and continue migrating things off of NativeMethodsMixin and NativeComponent.
If this becomes problematic for the Fabric rollout then we should revisit this.
* Fixing Flow
* Add FabricUIManager to externals for paper renderer
* import * as FabricUIManager from 'FabricUIManager';
* Update tests
* Shouldn't have removed UIManager import
* Update with the new tests
* Rewrite ReactFiberScheduler
Adds a new implementation of ReactFiberScheduler behind a feature flag.
We will maintain both implementations in parallel until the new one
is proven stable enough to replace the old one.
The main difference between the implementations is that the new one is
integrated with the Scheduler package's priority levels.
* Conditionally add fields to FiberRoot
Some fields only used by the old scheduler, and some by the new.
* Add separate build that enables new scheduler
* Re-enable skipped test
If synchronous updates are scheduled by a passive effect, that work
should be flushed synchronously, even if flushPassiveEffects is
called inside batchedUpdates.
* Passive effects have same priority as render
* Revert ability to cancel the current callback
React doesn't need this anyway because it never schedules callbacks if
it's already rendering.
* Revert change to FiberDebugPerf
Turns out this isn't neccessary.
* Fix ReactFiberScheduler dead code elimination
Should initialize to nothing, then assign the exports conditionally,
instead of initializing to the old exports and then reassigning to the
new ones.
* Don't yield before commit during sync error retry
* Call Scheduler.flushAll unconditionally in tests
Instead of wrapping in enableNewScheduler flag.
This took a while, but I'm happy I went through it. Some key moments - recursively flushing effects, flushing microtasks on each async turn, and my team's uncompromising philosophy on code reuse. Really happy with this. I still want to expand test coverage, and I have some more small related todos, but this is good to land. On to the next one.

it's an odd one, because not only does sync act not flush effects correctly, but the async one does (wut). verified it's fine with the dom version.
* lint
* rewrote to move flushing logic closer to the renderer
the scheduler's `flushPassiveEffects` didn't work as expected for the test renderer, so I decided to go back to the hack (rendering a dumb container) This also makes reactdom not as heavy (by a few bytes, but still).

we could have globally changed our eslint config to assume Promise is available, but that means we expect a promise polyfill on the page, and we don't yet. this code is triggered only in jest anyway, and we're fairly certain Promise will be available there. hence, the once-off disable for the check
* shorter timers, fix a test, test for Promise

simpler act() internals
ReactSharedInternals.ReactShouldWarnActingUpdates
* move act() implementation into createReactNoop
* warnIfNotCurrentlyActingUpdatesInDev condition check order
* Transform invariant to custom error type
This transforms calls to the invariant module:
```js
invariant(condition, 'A %s message that contains %s', adj, noun);
```
Into throw statements:
```js
if (!condition) {
if (__DEV__) {
throw ReactError(`A ${adj} message that contains ${noun}`);
} else {
throw ReactErrorProd(ERR_CODE, adj, noun);
}
}
```
The only thing ReactError does is return an error whose name is set
to "Invariant Violation" to match the existing behavior.
ReactErrorProd is a special version used in production that throws
a minified error code, with a link to see to expanded form. This
replaces the reactProdInvariant module.
As a next step, I would like to replace our use of the invariant module
for user facing errors by transforming normal Error constructors to
ReactError and ReactErrorProd. (We can continue using invariant for
internal React errors that are meant to be unreachable, which was the
original purpose of invariant.)
* Use numbers instead of strings for error codes
* Use arguments instead of an array
I wasn't sure about this part so I asked Sebastian, and his rationale
was that using arguments will make ReactErrorProd slightly slower, but
using an array will likely make all the functions that throw slightly
slower to compile, so it's hard to say which way is better. But since
ReactErrorProd is in an error path, and fewer bytes is generally better,
no array is good.
* Casing nit
* Swap expect(ReactNoop) for expect(Scheduler)
In the previous commits, I upgraded our custom Jest matchers for the
noop and test renderers to use Scheduler under the hood.
Now that all these matchers are using Scheduler, we can drop
support for passing ReactNoop and test roots and always pass
Scheduler directly.
* Externalize Scheduler in noop and test bundles
I also noticed we don't need to regenerator runtime in noop anymore.
* Replace test renderer's fake Scheduler implementation with mock build
The test renderer has its own mock implementation of the Scheduler
interface, with the ability to partially render work in tests. Now that
this functionality has been lifted into a proper mock Scheduler build,
we can use that instead.
* Fix Profiler tests in prod
* Replace noop's fake Scheduler implementation with mock Scheduler build
The noop renderer has its own mock implementation of the Scheduler
interface, with the ability to partially render work in tests. Now that
this functionality has been lifted into a proper mock Scheduler build,
we can use that instead.
Most of the existing noop tests were unaffected, but I did have to make
some changes. The biggest one involved passive effects: previously, they
were scheduled on a separate queue from the queue that handles
rendering. After this change, both rendering and effects are scheduled
in the Scheduler queue. I think this is a better approach because tests
no longer have to worry about the difference; if you call `flushAll`,
all the work is flushed, both rendering and effects. But for those few
tests that do care to flush the rendering without the effects, that's
still possible using the `yieldValue` API.
Follow-up: Do the same for test renderer.
* Fix import to scheduler/unstable_mock
* Add new mock build of Scheduler with flush, yield API
Test environments need a way to take control of the Scheduler queue and
incrementally flush work. Our current tests accomplish this either using
dynamic injection, or by using Jest's fake timers feature. Both of these
options are fragile and rely too much on implementation details.
In this new approach, we have a separate build of Scheduler that is
specifically designed for test environments. We mock the default
implementation like we would any other module; in our case, via Jest.
This special build has methods like `flushAll` and `yieldValue` that
control when work is flushed. These methods are based on equivalent
methods we've been using to write incremental React tests. Eventually
we may want to migrate the React tests to interact with the mock
Scheduler directly, instead of going through the host config like we
currently do.
For now, I'm using our custom static injection infrastructure to create
the two builds of Scheduler — a default build for DOM (which falls back
to a naive timer based implementation), and the new mock build. I did it
this way because it allows me to share most of the implementation, which
isn't specific to a host environment — e.g. everything related to the
priority queue. It may be better to duplicate the shared code instead,
especially considering that future environments (like React Native) may
have entirely forked implementations. I'd prefer to wait until the
implementation stabilizes before worrying about that, but I'm open to
changing this now if we decide it's important enough.
* Mock Scheduler in bundle tests, too
* Remove special case by making regex more restrictive
* Memoize promise listeners to prevent exponential growth
Previously, React would attach a new listener every time a promise is
thrown, regardless of whether the same listener was already attached
during a previous render. Because React attempts to render every time
a promise resolves, the number of listeners grows quickly.
This was especially bad in synchronous mode because the renders that
happen when the promise pings are not batched together. So if a single
promise has multiple listeners for the same root, there will be multiple
renders, which in turn results in more listeners being added to the
remaining unresolved promises. This results in exponential growth in
the number of listeners with respect to the number of IO-bound
components in a single render.
Fixes#14220
* Memoize on the root and Suspense fiber instead of on the promise
* Add TODO to fix persistent mode tests
* [Fizz] Add Flow/Jest/Rollup build infra
Add a new package for react-stream which allows for custom server renderer
outputs. I picked the name because it's a reasonable name but also
because the npm name is currently owned by a friend of the project.
The react-dom build has its own inlined server renderer under the
name `react-dom/fizz`.
There is also a noop renderer to be used for testing. At some point
we might add a public one to test-renderer but for now I don't want to have
to think about public API design for the tests.
* Add FormatConfig too
We need to separate the format (DOM, React Native, etc) from the host
running the server (Node, Browser, etc).
* Basic wiring between Node, Noop and DOM configs
The Node DOM API is pipeToNodeStream which accepts a writable stream.
* Merge host and format config in dynamic react-stream entry point
Simpler API this way but also avoids having to fork the wrapper config.
Fixes noop builds.
* Add setImmediate/Buffer globals to lint config
Used by the server renderer
* Properly include fizz.node.js
Also use forwarding to it from fizz.js in builds so that tests covers
this.
* Make react-stream private since we're not ready to publish
or even name it yet
* Rename Renderer -> Streamer
* Prefix react-dom/fizz with react-dom/unstable-fizz
* Add Fizz Browser host config
This lets Fizz render to WHATWG streams. E.g. for rendering in a
Service Worker.
I added react-dom/unstable-fizz.browser as the entry point for this.
Since we now have two configurations of DOM. I had to add another
inlinedHostConfigs configuration called `dom-browser`. The reconciler
treats this configuration the same as `dom`. For stream it checks
against the ReactFizzHostConfigBrowser instead of the Node one.
* Add Fizz Browser Fixture
This is for testing server rendering - on the client.
* Lower version number to detach it from react-reconciler version
* BUG: ReactPartialRenderer / New Context polutes mutable global state
The new context API stores the provided values on the shared context instance. When used in a synchronous context, this is not an issue. However when used in an concurrent context this can cause a "push provider" from one react render to have an effect on an unrelated concurrent react render.
I've encountered this bug in production when using renderToNodeStream, which asks ReactPartialRenderer for bytes up to a high water mark before yielding. If two Node Streams are created and read from in parallel, the state of one can polute the other.
I wrote a failing test to illustrate the conditions under which this happens.
I'm also concerned that the experimental concurrent/async React rendering on the client could suffer from the same issue.
* Use unique thread ID for each partial render to access Context
This first adds an allocator that keeps track of a unique ThreadID index
for each currently executing partial renderer. IDs are not just growing
but are reused as streams are destroyed.
This ensures that IDs are kept nice and compact.
This lets us use an "array" for each Context object to store the current
values. The look up for these are fast because they're just looking up
an offset in a tightly packed "array".
I don't use an actual Array object to store the values. Instead, I rely
on that VMs (notably V8) treat storage of numeric index property access
as a separate "elements" allocation.
This lets us avoid an extra indirection.
However, we must ensure that these arrays are not holey to preserve this
feature.
To do that I store the _threadCount on each context (effectively it takes
the place of the .length property on an array).
This lets us first validate that the context has enough slots before we
access the slot. If not, we fill in the slots with the default value.
* Parse build script type and package names
This ensures that `yarn build core dom` includes DOM.
It also ensures that spaces like `yarn build "core, dom"` doesn't build EVERYTHING.
* Get rid of label in bundles config
Instead we just use the name from entry using fuzzy search.
There is one special case. If you put in `/index` or `/index.js`.
That allows to build things like `react/index` to only build isomorphic
where as `react` would build everything. Or `react-dom/index` to exclude
the server renderers.
* Instead of matching `/index.js` just append it to the search string
That way things like `yarn build react/` works too.
* Add debug tools package
* Add basic implementation
* Implement inspection of the current state of hooks using the fiber tree
* Support useContext hooks inspection by backtracking from the Fiber
I'm not sure this is safe because the return fibers may not be current
but close enough and it's fast.
We use this to set up the current values of the providers.
* rm copypasta
* Use lastIndexOf
Just in case. I don't know of any scenario where this can happen.
* Support ForwardRef
* Add test for memo and custom hooks
* Support defaultProps resolution
* [react-cache] Remove `cache` as argument to `read`
Updated is API is `Resource.read(key)` instead of
`Resource.read(cache, key)`.
The cache is read from context using `readContext`.
This also removes cache invalidation entirely (other than the default
LRU mechanism), as well as the ability to have multiple caches. We'll
add it back once `Context.write` lands and we can implement it the
right way.
Since there's now only a single cache (the global one), we don't
actually need to use context yet, but I've added a dummy context
anyway so the user gets an error if they attempt to read outside the
render phase.
* nits
* Add test for thenables that resolve multiple times
* Jest + test renderer helpers for concurrent mode
Most of our concurrent React tests use the noop renderer. But most
of those tests don't test the renderer API, and could instead be
written with the test renderer. We should switch to using the test
renderer whenever possible, because that's what we expect product devs
and library authors to do. If test renderer is sufficient for writing
most React core tests, it should be sufficient for others, too. (The
converse isn't true but we should aim to dogfood test renderer as much
as possible.)
This PR adds a new package, jest-react (thanks @cpojer). I've moved
our existing Jest matchers into that package and added some new ones.
I'm not expecting to figure out the final API in this PR. My goal is
to land something good enough that we can start dogfooding in www.
TODO: Continue migrating Suspense tests, decide on better API names

- Errors if user attempts to flush when log of yields is not empty
- Throws if argument passed to toClearYields is not ReactTestRenderer

injectComponentTree was exposed for react-native-web, but wasn't
actually being used by the project. They were using EventPluginHub
through ReactDOM's secret internals, but that was removed in https://github.com/facebook/react/pull/13539
This removes the unused injectComponentTree export, refactors the
ResponderEventPlugin test so it doesn't depend on it, and also adds
EventPluginHub to the exports to unbreak react-native-web

* 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
* 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 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
* add legacy context APIs warning in strict mode
* refactor if statement and the warning message
* add other flags for type check
* add component stack tree and refactor wording
* fix the nits
* Extract base Jest config
This makes it easier to change the source config without affecting the build test config.
* Statically import the host config
This changes react-reconciler to import HostConfig instead of getting it through a function argument.
Rather than start with packages like ReactDOM that want to inline it, I started with React Noop and ensured that *custom* renderers using react-reconciler package still work. To do this, I'm making HostConfig module in the reconciler look at a global variable by default (which, in case of the react-reconciler npm package, ends up being the host config argument in the top-level scope).
This is still very broken.
* Add scaffolding for importing an inlined renderer
* Fix the build
* ES exports for renderer methods
* ES modules for host configs
* Remove closures from the reconciler
* Check each renderer's config with Flow
* Fix uncovered Flow issue
We know nextHydratableInstance doesn't get mutated inside this function, but Flow doesn't so it thinks it may be null.
Help Flow.
* Prettier
* Get rid of enable*Reconciler flags
They are not as useful anymore because for almost all cases (except third party renderers) we *know* whether it supports mutation or persistence.
This refactoring means react-reconciler and react-reconciler/persistent third-party packages now ship the same thing.
Not ideal, but this seems worth how simpler the code becomes. We can later look into addressing it by having a single toggle instead.
* Prettier again
* Fix Flow config creation issue
* Fix imprecise Flow typing
* Revert accidental changes
* Temporary fix for grabbing wrong rAF polyfill in ReactScheduler
**what is the change?:**
For now...
We need to grab a slightly different implementation of rAF internally at
FB than in Open Source. Making rAF a dependency of the ReactScheduler
module allows us to fork the dependency at FB.
NOTE: After this lands we have an alternative plan to make this module
separate from React and require it before our Facebook timer polyfills
are applied. But want to land this now to keep master in a working state
and fix bugs folks are seeing at Facebook.
Thanks @sebmarkbage @acdlite and @sophiebits for discussing the options
and trade-offs for solving this issue.
**why make this change?:**
This fixes a problem we're running into when experimenting with
ReactScheduler internally at Facebook, **and* it's part of our long term
plan to use dependency injection with the scheduler to make it easier to
test and adjust.
**test plan:**
Ran tests, lint, flow, and will manually test when syncing into
Facebook's codebase.

* Added new "native-fb" and "native-fabric-fb" bundles.
* Split RN_DEV and RN_PROD bundle types into RN_OSS_DEV, RN_OSS_PROD, RN_FB_DEV, and RN_FB_PROD. (This is a bit redundant but it seemed the least intrusive way of supporting a forked feature flags file for these bundles.)
* Renamed FB_DEV and FB_PROD bundle types to be more explicitly for www (FB_WWW_DEV and FB_WWW_PROD)
* Removed Haste @providesModule headers from the RB-specific RN renderer bundles to avoid a duplicate name conflicts.
* Remove dynamic values from OSS RN feature flags. (Leave them in FB RN feature flags.)
* Updated the sync script(s) to account for new renderer type.
* Move ReactFeatureFlags.js shim to FB bundle only (since OSS bundle no longer needs dynamic values).
* Don't download bundle stats from master on CI
This was temporarily necessary in the past because we didn't have the logic that downloads actual *merge base* stats.
We do have that now as part of the Danger script. So we can remove this.
* Use absolute threshold for whether to show a change
* Download master stats, but only for other master builds
* Rewrite sizes
* Move view config registry to shims
This ensures that both Fabric and RN renderers share the same view config
registry since it is stateful.
I had to duplicate in the mocks for testing.
* Move createReactNativeComponentClass to shims and delete internal usage
Since createReactNativeComponentClass is just an alias for the register
there's no need to bundle it. This file should probably just move back
to RN too.
We already have one stateful module that contains all the view config.
We might as well store the event types there too. That way the shared
state is compartmentalized (and I can move it out in a follow up PR).
The view config registry also already has an appropriate place to call
processEventTypes so now we no longer have to do it in RN.
Will follow up with a PR to RN to remove that call.
These are based on the ReactNoop renderer, which we use to test React
itself. This gives library authors (Relay, Apollo, Redux, et al.) a way
to test their components for async compatibility.
- Pass `unstable_isAsync` to `TestRenderer.create` to create an async
renderer instance. This causes updates to be lazily flushed.
- `renderer.unstable_yield` tells React to yield execution after the
currently rendering component.
- `renderer.unstable_flushAll` flushes all pending async work, and
returns an array of yielded values.
- `renderer.unstable_flushThrough` receives an array of expected values,
begins rendering, and stops once those values have been yielded. It
returns the array of values that are actually yielded. The user should
assert that they are equal.
Although we've used this pattern successfully in our own tests, I'm not
sure if these are the final APIs we'll make public.
* Don't expose ReactGlobalSharedState on React Native renderer
We should just go through the "react" package if need access to this one.

* Change invariant to DEV-only warning
* Use function overloading for createResource type
Expresses that primitive keys do not require a hash function, but
non-primitive keys do.
* More tests
* Use export *
* Make Record type a disjoint union
* Pass miss argument separate from key to avoid a closure
* [Danger] Use the PR's mergebase for a branch in the dangerfile instead of
the root commit's parent.
* [Danger] Get the full history to find the merge base
* Adds danger_js with an initial rule for warning about large PRs
Signed-off-by: Anandaroop Roy <roop@artsymail.com>
* [WIP] Get the before and after for the build results
* [Dev] More work on the Dangerfile
* [Danger] Split the reports into sections based on their package
* Remove the --extract-errors on the circle build
* [Danger] Improve the lookup for previous -> current build to also include the environment
* Fix rebase
* Move build/packages/* to build/node_modules/*
This fixes Node resolution in that folder and lets us require() packages in it in Node shell for manual testing.
* Link fixtures to packages/node_modules
This updates the location and also uses link: instead of file: to avoid Yarn caching the folder contents.
* use different eslint config for es6 and es5
* remove confusing eslint/baseConfig.js & add more eslint setting for es5, es6
* more clear way to run eslint on es5 & es6 file
* seperate ESNext, ES6, ES6 path, and use different lint config
* rename eslint config file & update eslint rules
* Undo yarn.lock changes
* Rename a file
* Remove unnecessary exceptions
* Refactor a little bit
* Refactor and tweak the logic
* Minor issues
* Remove EventListener fbjs utility
EventListener normalizes event subscription for <= IE8. This is no
longer necessary. element.addEventListener is sufficient.
* Remove an extra allocation for open source bundles
* Split into two functions to avoid extra runtime checks
* Revert unrelated changes
* Rewrite the build scripts
* Don't crash when doing FB-only builds
* Group sync imports under Sync.*
* Don't print known errors twice
* Use an exclamation that aligns vertically
* Change build process to include npm pack and unpacking generated packages to corresponding build directories.
* Update function name, change to use os's default temp directory
* appending uuid to temp npm packaging directory.
* Use `this` inside invokeGuardedCallback
It's slightly odd but that's exactly how our www fork works.
Might as well do it in the open source version to make it clear we rely on context here.
* Move invokeGuardedCallback into a separate file
This lets us introduce forks for it.
* Add a www fork for invokeGuardedCallback
* Fix Flow
* Unify the way we fork modules
* Replace rollup-plugin-alias with our own plugin
This does exactly what we need and doesn't suffer from https://github.com/rollup/rollup-plugin-alias/issues/34.
* Move the new plugin to its own file
* Rename variable for consistency
I settled on calling them "forks" since we already have a different concept of "shims".
* Move fork config into its own file
* Move ReactFiberTreeReflection to react-reconciler/reflection #11659
* Use * for react-reconciler
We don't know the latest local version, and release script currently doesn't bump deps automatically.
* Remove unused field
* Use CommonJS in entry point for consistency
* Undo the CommonJS change
I didn't realize it would break the build.
* Record sizes
* Remove reconciler fixtures
They're unnecessary now that we run real tests on reconciler bundles.
* Extract Jest config into a separate file
* Refactor Jest scripts directory structure
Introduces a more consistent naming scheme.
* Add yarn test-bundles and yarn test-prod-bundles
Only files ending with -test.public.js are opted in (so far we don't have any).
* Fix error decoding for production bundles
GCC seems to remove `new` from `new Error()` which broke our proxy.
* Build production version of react-noop-renderer
This lets us test more bundles.
* Switch to blacklist (exclude .private.js tests)
* Rename tests that are currently broken against bundles to *-test.internal.js
Some of these are using private APIs. Some have other issues.
* Add bundle tests to CI
* Split private and public ReactJSXElementValidator tests
* Remove internal deps from ReactServerRendering-test and make it public
* Only run tests directly in __tests__
This lets us share code between test files by placing them in __tests__/utils.
* Remove ExecutionEnvironment dependency from DOMServerIntegrationTest
It's not necessary since Stack.
* Split up ReactDOMServerIntegration into test suite and utilities
This enables us to further split it down. Good both for parallelization and extracting public parts.
* Split Fragment tests from other DOMServerIntegration tests
This enables them to opt other DOMServerIntegration tests into bundle testing.
* Split ReactDOMServerIntegration into different test files
It was way too slow to run all these in sequence.
* Don't reset the cache twice in DOMServerIntegration tests
We used to do this to simulate testing separate bundles.
But now we actually *do* test bundles. So there is no need for this, as it makes tests slower.
* Rename test-bundles* commands to test-build*
Also add test-prod-build as alias for test-build-prod because I keep messing them up.
* Use regenerator polyfill for react-noop
This fixes other issues and finally lets us run ReactNoop tests against a prod bundle.
* Run most Incremental tests against bundles
Now that GCC generator issue is fixed, we can do this.
I split ErrorLogging test separately because it does mocking. Other error handling tests don't need it.
* Update sizes
* Fix ReactMount test
* Enable ReactDOMComponent test
* Fix a warning issue uncovered by flat bundle testing
With flat bundles, we couldn't produce a good warning for <div onclick={}> on SSR
because it doesn't use the event system. However the issue was not visible in normal
Jest runs because the event plugins have been injected by the time the test ran.
To solve this, I am explicitly passing whether event system is available as an argument
to the hook. This makes the behavior consistent between source and bundle tests. Then
I change the tests to document the actual logic and _attempt_ to show a nice message
(e.g. we know for sure `onclick` is a bad event but we don't know the right name for it
on the server so we just say a generic message about camelCase naming convention).
* Forked ReactFeatureFlags for React Native to enable debugRenderPhaseSideEffects GK
* Changed debugRenderPhaseSideEffects in www feature flags to be runtime as well
* Improve formatting of errors when building
* Remove undefined from the header when error.plugin is undefined
* Add babel-code-frame and syntax highlighting in error message
* Run yarn prettier and fix code format
* Don't call idle callback unless there's time remaining
* Expiration fixture
Fixture that demonstrates how async work expires after a certain interval.
The fixture clogs the main thread with animation work, so it only works if the
`timeout` option is provided to `requestIdleCallback`.
* Pass timeout option to requestIdleCallback
Forces `requestIdleCallback` to fire if too much time has elapsed, even if the
main thread is busy. Required to make expiration times work properly. Otherwise,
async work can expire, but React never has a chance to flush it because the
browser never calls into React.
* Consolidate build process with GCC
* Record sizes
* Refactor header and footer wrapping
It is easier to understand if we just explicitly type them out.
