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.
`oldProps` was null. This went uncaught by the unit tests because
ReactNoop did not use `oldProps` in either `prepareUpdate` or
`completeUpdate`. I added some invariants so we don't regress in
the future.
* Add stack unwinding phase for handling errors
A rewrite of error handling, with semantics that more closely match
stack unwinding.
Errors that are thrown during the render phase unwind to the nearest
error boundary, like before. But rather than synchronously unmount the
children before retrying, we restart the failed subtree within the same
render phase. The failed children are still unmounted (as if all their
keys changed) but without an extra commit.
Commit phase errors are different. They work by scheduling an error on
the update queue of the error boundary. When we enter the render phase,
the error is popped off the queue. The rest of the algorithm is
the same.
This approach is designed to work for throwing non-errors, too, though
that feature is not implemented yet.
* Add experimental getDerivedStateFromCatch lifecycle
Fires during the render phase, so you can recover from an error within the same
pass. This aligns error boundaries more closely with try-catch semantics.
Let's keep this behind a feature flag until a future release. For now, the
recommendation is to keep using componentDidCatch. Eventually, the advice will
be to use getDerivedStateFromCatch for handling errors and componentDidCatch
only for logging.
* Reconcile twice to remount failed children, instead of using a boolean
* Handle effect immediately after its thrown
This way we don't have to store the thrown values on the effect list.
* ReactFiberIncompleteWork -> ReactFiberUnwindWork
* Remove startTime
* Remove TypeOfException
We don't need it yet. We'll reconsider once we add another exception type.
* Move replay to outer catch block
This moves it out of the hot path.
* Updates inside controlled events (onChange) are sync even in async mode
This guarantees the DOM is in a consistent state before we yield back
to the browser.
We'll need to figure out a separate strategy for other
interactive events.
* Don't rely on flushing behavior of public batchedUpdates implementation
Flush work as an explicit step at the end of the event, right before
restoring controlled state.
* Interactive updates
At the beginning of an interactive browser event (events that fire as
the result of a user interaction, like a click), check for pending
updates that were scheduled in a previous interactive event. Flush the
pending updates synchronously so that the event handlers are up-to-date
before responding to the current event.
We now have three classes of events:
- Controlled events. Updates are always flushed synchronously.
- Interactive events. Updates are async, unless another a subsequent
event is fired before it can complete, as described above. They are
also slightly higher priority than a normal async update.
- Non-interactive events. These are treated as normal, low-priority
async updates.
* Flush lowest pending interactive update time
Accounts for case when multiple interactive updates are scheduled at
different priorities. This can happen when an interactive event is
dispatched inside an async subtree, and there's an event handler on
an ancestor that is outside the subtree.
* Update comment about restoring controlled components
* WIP:use public API
* ReactPortal shifted to shared:all passed
* wrote createPortal method for ReactNoop.(#11299)
* imported ReactNodeList type into ReactNoop.(#11299)
* createPortal method implemented.(#11299)
* exec yarn prettier-all.(#11299)
* 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).
When we're rendering work at a specific level, and a higher priority
update comes in, we interrupt the current work and restart at the
higher priority. The rationale is that the high priority update is
likely cheaper to render that the lower one, so it's usually worth
throwing out the current work to get the high pri update on the screen
as soon as possible.
Currently, we also interrupt the current work if an update of *equal*
priority is scheduled. The rationale here is less clear: the only reason
to do this is if both updates are expected to flush at the same time,
to prevent tearing. But this usually isn't the case. Separate setStates
are usually distinct updates that can be flushed separately, especially
if the components that are being updated are in separate subtrees.
An exception is in Flux-like systems where multiple setStates are the
result of a single conceptual update/event/dispatch. We can add an
explicit API for batching in the future; in fact, we'd likely need one
anyway to account for expiration accidentally causing consecutive
updates to fall into separate buckets.
* 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.
* 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.

* Update Jest
* Remove hacks for Jest + Workspace integration
They were fixed by https://github.com/facebook/jest/pull/4761.
* Use relative requires in tests relying on private APIs
I changed them to absolute to work around a Jest bug.
The bug has been fixed so I can revert my past changes now.
* 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.

* 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
NOTE: This commit is not exactly what went out as RC2 because I forgot to push. See tag v16.0.0-rc.2 (d06680ea9e) instead. Bumping the version here so we're at the right place though.
