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.
* Remove internal forwarding modules for /lib/
* Add *Entry suffix to all entry points
* Don't bundle ReactNativeFeatureFlags since it's shimmed
* Delete TestRendererStack
* Switch tests at forwarding modules rather than via Jest
* Share mocks between regular and equivalence fixtures
* Rename environment flag to be more generic
* Remove accidental variable name change
* Minor naming changes for consistency
Files that have two versions get the engine in variable name.
* Make ReactControlledValuePropTypes DEV-only
* Remove canDefineProperty
This breaks IE8. We don't support it.
* Remove getNextDebugID
It was added temporarily to avoid Stack shared state issues across renderers.
Not a problem anymore.
* Make KeyEscapeUtils.unescape() DEV-only
* Remove unused deprecated() module
It's unlikely we'll deprecate anything else on React.* object soon.
* Inline getIteratorFn at the call sites
* Inline ReactElementSymbol
* Inline KeyEscapeUtils into Children and move the file into Stack
It's only used in one place in isomorphic.
It's used more broadly in Stack so we move it there to die.
* Update artifacts
* Reorder declarations for consistency
* Fix Flow
* 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
**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.
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 allow easier debugging using 'pause on caught errors'
- 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.

Apparently, when you mark something as external in Rollup, a require
statement is inserted even if the module isn't used. This is causing
ReactDOM and several other modules to be inserted unnecessarily.
We need a better fix for this, but I'm pushing this quick fix for
now since it's blocking sync to www.
Latest versions of prop-types don't depend on React, so the factory is
not necessary, and in fact bloats the build because it is intended for
15.5 and so doesn't strip out the checkers in prod.
Shallow renderer and test utils bundles
Adds new bundles introduced with React 15.5 release to master (and 16 alpha)
react-dom/test-utils:
This new bundle contains what used to be react-addons-test-utils. This bundle shares things from react-dom rather than duplicates them.
A temporary createRenderer method has been left behind as a way to access the new shallow renderer. This is for the ReactNative release cycle only and should be going away before the final release.
react-test-renderer/shallow:
This new shallow renderer is almost entirely stand-alone (in that it doesn't use the React reconciler or scheduler). The only touch points are ReactElement and prop/context validation. This renderer is stack and fiber compatible.
* Fix tests to pass when we warn for missing keys in fragments
In most cases we just needed to add the 'key' prop.
This ignores the tests which are already failing on master when running
with ` REACT_DOM_JEST_USE_FIBER=1` - there are 8.
All tests should now pass with `npm run test`, and the 8 which fail when
running `REACT_DOM_JEST_USE_FIBER=1 npm run test` are the same 8 which
are failing on master.
* Added missing key warning for children in array fragments
After trying twice to reuse the code between the ReactChildFiber and
ReactElementValidator, I am thinking that it's simpler to just have some
duplication of code. The parts that are shared are interleaved with
parts which cannot be shared, either because of singleton modules that
must be required differently in 'isomorphic' and the 'renderers', or the
fact that 'warning' requires a hard coded string.
Test Plan:
- Added test to ReactChildren-test
- Manually tested via fixture that was not committed.
* commit updated "scripts/rollup/results.json"
* Make 'ReactChildren-test' more specific, and remove unneeded nesting
Based on helpful tips from @spicyj and @aweary's review
- Made the unit test for the warning on missing keys more specific
- Removed unneeded nesting in the code which generates missing key
warning
- Change test syntax to use JSX to be more consistent
Also fixes flow warning.
* Commit update of scripts/rollup/results.json
* run "scripts/fiber/record-tests"
