* Move Flight DOM to Webpack Specific Packagee
We'll have Webpack specific coupling so we need to ensure that it can be
versioned separately from various Webpack versions. We'll also have builds
for other bundlers in the future.
* Move to peerDep
* Move DOM Flight Tests
* Merge ReactFlightIntegration into ReactFlightDOM
This was an integration test. We can add to it.
* Fix fixture paths
* Return whether to keep flowing in Host config
* Emit basic chunk based streaming in the Flight server
When something suspends a new chunk is created.
* Add reentrancy check
The WHATWG API is designed to be pulled recursively.
We should refactor to favor that approach.
* Basic streaming Suspense support on the client
* Add basic suspense in example
* Add comment describing the protocol that the server generates
* Rename ReactFlightStreamer -> ReactFlightServer
* Unify Browser/Node stream tests into one file and use the client reader
* Defer to the actual ReactDOM for HTML rendering for now
This will need to use a variant of Fizz to do inline SSR in Flight.
However, I don't want to build the whole impl right now but also don't
want to exclude the use case yet. So I outsource it to the existing
renderer. Ofc, this doesn't work with Suspense atm.
* Change demo to server
* Expose client in package.json
* Reorganize tests
We don't want unit tests but instead test how both server and clients work
together. So this merges server/client test files.
* Fill in the client implementation a bit
* Use new client in fixture
* Add Promise/Uint8Array to lint rule
I'll probably end up deleting these deps later but they're here for now.
* Add Flight Build and Unify HostFormat Config between Flight and Fizz
* Add basic resolution of models
* Add basic Flight fixture
Demonstrates the streaming protocol.
* Rename to flight-server to distinguish from the client parts
* Add Flight Client package and entry point
* Fix fixture
* Tests run in experimental mode by default
For local development, you usually want experiments enabled. Unless
the release channel is set with an environment variable, tests will
run with __EXPERIMENTAL__ set to `true`.
* Remove concurrent APIs from stable builds
Those who want to try concurrent mode should use the experimental
builds instead.
I've left the `unstable_` prefixed APIs in the Facebook build so we
can continue experimenting with them internally without blessing them
for widespread use.
* Turn on SSR flags in experimental build
* Remove prefixed concurrent APIs from www build
Instead we'll use the experimental builds when syncing to www.
* Remove "canary" from internal React version string
* prevent firefox marking required textareas invalid
Bug was caused by an IE10/IE11 bugfix dealing with the placeholder attribute and textContent. Solved by avoiding the IE bugfix when textContent was empty.
Closes#16402
* more explicit conditional check for textContent
re: @philipp-spiess code review
* clarify textarea test fixture's expected result
better describe the behavior we are testing for
re: @philipp-spiess code review
* Test that we can suspend updates while waiting to hydrate
* Attempt hydration at a higher pri first if props/context changes
* Retrying a dehydrated boundary pings at the earliest forced time
This might quickly become an already expired time.
* Mark the render as delayed if we have to retry
This allows the suspense config to kick in and we can wait for much longer
before we're forced to give up on hydrating.
Concurrent/Batched mode tests should always be run with a mocked scheduler (v17 or not). This PR adds a warning for the same. I'll put up a separate PR to the docs with a page detailing how to mock the scheduler.
Given this snippet:
```jsx
TestRenderer.act(() => {
TestUtils.act(() => {
TestRenderer.create(<Effecty />);
});
});
```
We want to make sure that all work is only flushed on exiting the outermost act().
Now, naively doing this based on actingScopeDepth would work with a mocked scheduler, where flushAll() would flush all work across renderers.
This doesn't work without mocking the scheduler though; and where flushing work only works per renderer. So we disable this behaviour for a non-mocked scenario. This seems like an ok tradeoff.
* Add version 4 react-devtools and react-devtools-core packages which support both React Native and e.g. Safari or iframe DOM usage.
* Replaces typed operations arrays with regular arrays in order to support Hermes. This is unfortunate, since in theory a typed array buffer could be more efficiently transferred between frontend and backend for the web extension, but this never actually worked properly in v8, only Spidermonkey, and it fails entirely in Hermes so for the time being- it's been removed.
* Adds support for React Native (paper renderer)
* Adds a style editor for react-native and react-native-web
* [fail] reset IsThisRendererActing correctly
I missed this in https://github.com/facebook/react/pull/16039. I'd pointed at the wrong previous state, corrupting it in further use. This PR fixes that, and adds a test to make sure it doesn't happen again.
* warn for unacted effects only in strict mode
* allow nested `act()`s from different renderers
There are usecases where multiple renderers need to oprate inside an act() scope
- ReactDOM.render being used inside another component tree. The parent component will be rendered using ReactTestRenderer.create for a snapshot test or something.
- a ReactDOM instance interacting with a ReactTestRenderer instance (like for the new devtools)
This PR changes the way the acting sigils operate to allow for this. It keeps 2 booleans, one attached to React, one attached to the renderer. act() changes these values, and the workloop reads them to decide what warning to trigger.
I also renamed shouldWarnUnactedUpdates to warnsIfNotActing
* s/ReactIsActing/IsSomeRendererActing and s/ReactRendererIsActing/IsThisRendererActing
* use toWarnDev for dom fixture tests
forks toWarnDev from root into fixture/dom, updates tes tests to use it
* disable act() warnings for react-art()
- For 'secondary' renderers like react-act, we don't want to fire missing act() warnings; the wrapping renderer will fire warnings anyway, and when it flushes, it flushes effects *across* renderers.
- I could have used isPrimaryRenderer as the flag, but this is marked as false for react-test-renderer, and we *do* want the warning to fire for it. Hence a new flag.
* add missing dependency `art` to fixtures/dom
* warn when using the wrong renderer's act around another renderer's updates
like it says. it uses a real object as the sigil (instead of just a boolean). specifically, it uses a renderer's flushPassiveEffects as the sigil. We also run tests for this separate from our main suite (which doesn't allow loading multiple renderers in a suite), but makes sure to run this in CI as well.
* unneeded (and wrong) comment
* run the dom fixture on CI
* update the sigil only in __DEV__
* remove the obnoxious comment
* use an explicit export for the sigil
* s/flushPassiveEffects/unstable_flushWithoutYielding
a first crack at flushing the scheduler manually from inside act(). uses unstable_flushWithoutYielding(). The tests that changed, mostly replaced toFlushAndYield(...) with toHaveYielded(). For some tests that tested the state of the tree before flushing effects (but still after updates), I replaced act() with bacthedUpdates().
* ugh lint
* pass build, flushPassiveEffects returns nothing now
* pass test-fire
* flush all work (not just effects), add a compatibility mode
of note, unstable_flushWithoutYielding now returns a boolean much like flushPassiveEffects
* umd build for scheduler/unstable_mock, pass the fixture with it
* add a comment to Shcduler.umd.js for why we're exporting unstable_flushWithoutYielding
* run testsutilsact tests in both sync/concurrent modes
* augh lint
* use a feature flag for the missing mock scheduler warning
I also tried writing a test for it, but couldn't get the scheduler to unmock. included the failing test.
* Update ReactTestUtilsAct-test.js
- pass the mock scheduler warning test,
- rewrite some tests to use Scheduler.yieldValue
- structure concurrent/legacy suites neatly
* pass failing tests in batchedmode-test
* fix pretty/lint/import errors
* pass test-build
* nit: pull .create(null) out of the act() call
* ADD: disablePictureInPicture attribute for HTML5 videos
* ADD: disablePictureInPicture as DOMProperty and attribute
* Update: Replace camelCase with lowercase and vice-versa
* FIX: Missing comma on attribute (prettier)
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.
Soundtrack to landing this - https://open.spotify.com/track/0MF8I8OUo8kytiOo8aSHYq?si=gSWqUheKQbiQDXzptCXHTg
* hacked up act(async () => {...})
* move stuff around
* merge changes
* abstract .act warnings and stuff. all renderers. pass all tests.
* move testutils.act back into testutils
* move into scheduler, rename some bits
* smaller bundle
* a comment for why we don't do typeof === 'function'
* fix test
* pass tests - fire, prod
* lose actContainerElement
* tighter
* write a test for TestRenderer
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).
* move it around so the delta isn't too bad
* cleanups
fix promise chaining
propagate errors correctly
test for thenable the 'right' way
more tests!
tidier!
ponies!
* Stray comment
* recursively flush effects
* fixed tests
* lint, move noop.act into react-reconciler
* microtasks when checking if called, s/called/calledLog, cleanup
* pass fb lint
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
* use global.Promise for existence check
* flush microtasks
* a version that works in browsers (that support postMessage)
I also added a sanity fixture inside fixtures/dom/ mostly for me.
* hoist flushEffectsAndMicroTasks
* pull out tick logic from ReactFiberScheduler
* fix await act (...sync) hanging
- fix a hang when awaiting sync logic
- a better async/await test for test renderer
* feedback changes
- use node's setImmediate if available
- a warning if MessageChannel isn't available
- rename some functions
* pass lint/flow checks (without requiring a Promise polyfill/exclusion)
* prettier
the prettiest, even.
* use globalPromise for the missed await warning
* __DEV__ check for didWarnAboutMessageChannel
* thenables and callbacks instead of promises, pass flow/lint
* tinier. better.
- pulled most bits out of FiberScheduler
- actedUpdates uses callbacks now
* pass build validation
* augh prettier
* golfing 7 more chars
* Test that effects are not flushed without also flushing microtasks
* export doesHavePendingPassiveEffects, nits
* createAct()
* dead code
* missed in merge?
* lose the preflushing bits
* ugh prettier
* removed `actedUpdates()`, created shared/actingUpdatesScopeDepth
* rearrange imports so builds work, remove the hack versions of flushPassiveEffects
* represent actingUpdatesScopeDepth as a tuple [number]
* use a shared flag on React.__SECRET...
* remove createAct, setup act for all relevant renderers
* review feedback
shared/enqueueTask
import ReactSharedInternals from 'shared/ReactSharedInternals';
simpler act() internals
ReactSharedInternals.ReactShouldWarnActingUpdates
* move act() implementation into createReactNoop
* warnIfNotCurrentlyActingUpdatesInDev condition check order
* Set 'size' attribute to select tag if it occurs before appending options
* Add comment about why size is assigned on select create. Tests
I added some more clarification for why size must be set on select
element creation:
- In the source code
- In the DOM test fixture
- In a unit test
* Use let, not const in select tag stub assignment
* Hydration Fixture: Only load ReactDOMServer if it exists
Fixes an issue where the hydration fixture would try to load in
ReactDOMServer below version 14. In version 13, string markup methods
exist on the React namespace.
* DOM Fixtures: Use class component for App.js
This was breaking React 0.13.0.
* Hydration Fixture: better findDOMNode compatibility
This commit fixes an issue where the Hydration DOM fixture was
unusable in React 0.13.0 or lower because of newer API usage.
It fixes that by avoiding the use of refs to get the textarea
reference in the code editor component, using various versions of
findDOMNode as required.
* Hydration Fixture: Do not show dropdown for single-line errors
If an error showed for the hydration fixture, a detail element was
used even if no additional lines could display. In that case, this
commit changes the component such that it returns a div.
* Deeper React version support for hydration fixture
This commit adds support for versions 0.4.0 of React and higher for
the hydration fixture.
The DOM test fixtures themselves do not support down to React 0.4.0,
which would be exhaustive. Instead, the Hydration fixture can pick a
version to use for its own purposes. By default, this is the version
of React used by the fixtures.
In the process of doing this, I had to make some updates to the
renderer.html document associated with the hydration fixture, and I've
added some comments to better document the history of API changes.
