* [Flight] Basic Integration Test
* Just act()
* Lint
* Remove unnecessary acts
* Use Concurrent Mode
* it.experimental
* Fix prod test by advancing time
* Don't observe initial state
* 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
1. Add a Store test for memo, lazy, and forwardRef components
2. Remove dead code for React.lazy
3. Update DT tests to include HOC badge names in the serialized store
* [react-is] return correct typeOf value of forwardRef
* [react-devtools-shared] use correct displayName of memo(forwardRef(Component))
* [react-devtools-shared] add resolveFiberType and resolve fiber type of memo recursively
Resolving the fiber type of memo recursively before passing it to getDisplayName
will prevent it from displaying "Anonymous" as displayName for components
wrapped with both memo and forwardRef: memo(forwardRef(Component))
* rework resolveFiberType
There are two similar flags, `debugRenderPhaseSideEffects` and
`debugRenderPhaseSideEffectsForStrictMode`. The strict mode one is the
only one that is actually used. I think originally the theory is that
we would one day turn it on for all components, even outside strict
mode. But what we'll do instead is migrate everyone to strict mode.
The only place `debugRenderPhaseSideEffects` was being used was in
an internal test file. I rewrote those tests to use public APIs.
* 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.
`it.experimental` marks that a test only works in Experimental builds.
It also asserts that a test does *not* work in the stable builds. The
main benefit is that we're less likely to accidentally expose an
experimental API before we intend. It also forces us to un- mark an
experimental test once it become stable.
* Add CodeSandbox CI Config
* Add default sandbox to build
* Make build more efficient and add scheduler
* Force build
* Add scheduler image
* Add scheduler/tracing to the build
* Force another build
* 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
Already mounted rows that resuspend may be considered as part of a tail
if they're at the end. However, for purposes of the tail="..." option
they don't get deleted. We deal with that in cutOffTailIfNeeded.
However, if they're also the first to suspend in the "hidden" case, we have
a special case that deletes the actual rendered row. This needs to consider
if that row was already mounted or things go wrong.
* Failing test: DevTools hook freezes timeline
The DevTools hook calls `requestCurrentTime` after the commit phase has
ended, which has the accidnental consequence of freezing the start
time for subsequent updates. If enough time goes by, the next update
will instantly expire.
I'll push a fix in the next commit.
* Read current time without marking event start time
`requestCurrentTime` is only meant to be used for updates, because
subsequent calls within the same event will receive the same time.
Messing this up has bad consequences.
I renamed it to `requestCurrentTimeForUpdate` and created a new
function that returns the current time without the batching heuristic,
called `getCurrentTime`.
Swapping `requestCurrentTime` for `getCurrentTime` in the DevTools
hook fixes the regression test added in the previous commit.
Special version of Jest's `it` for experimental tests. Tests marked as
experimental will run **both** stable and experimental modes. In
experimental mode, they work the same as the normal Jest methods. In
stable mode, they are **expected to fail**. This means we can detect
when a test previously marked as experimental can be un-marked when the
feature becomes stable. It also reduces the chances that we accidentally
add experimental APIs to the stable builds before we intend.
I added corresponding methods for the focus and skip APIs:
- `fit` -> `fit.experimental`
- `it.only` -> `it.only.experimental` or `it.experimental.only`
- `xit` -> `xit.experimental`
- `it.skip` -> `it.skip.experimental` or `it.experimental.skip`
Since `it` is an alias of `test`, `test.experimental` works, too.
`yarn build` defaults to building in experimental mode. To opt-out, set
the `RELEASE_CHANNEL` environment variable to `stable`. This is the same
as what we do when running tests via `yarn test`, to make local
development easier.
* SuspenseList support in DevTools
This adds SuspenseList tags to DevTools so that the name properly shows
up.
It also switches to use the tag instead of Symbol type for Suspense
components. We shouldn't rely on the type for any built-ins since that
field will disappear from the fibers. How the Fibers get created is an
implementation detail that can change e.g. with a compiler or if we
use instanceof checks that are faster than symbol comparisons.
* Add SuspenseList test to shell app
