1. Run the tests in both an environment without PointerEvent and one with PointerEvent.
2. Improve test coverage to include both mouse and touch pointers.
3. Change 'Press' so that it only listens to either pointer events or fallbacks events.
* Fixed issue with def being undefined while referencing arguments.
* Removed todo comment.
* Skip exhaustive deps check if def is null.
* Fixed code formatting in ExhaustiveDeps.
* Removed unneeded comment in ExhaustiveDeps.
* [Scheduler] Mark user-timing events
Marks when Scheduler starts and stops running a task. Also marks when
a task is initially scheduled, and when Scheduler is waiting for a
callback, which can't be inferred from a sample-based JavaScript CPU
profile alone.
The plan is to use the user-timing events to build a Scheduler profiler
that shows how the lifetime of tasks interact with each other and
with unscheduled main thread work.
The test suite works by printing an text representation of a
Scheduler flamegraph.
* Expose shared array buffer with profiling info
Array contains
- the priority Scheduler is currently running
- the size of the queue
- the id of the currently running task
* Replace user-timing calls with event log
Events are written to an array buffer using a custom instruction format.
For now, this is only meant to be used during page start up, before the
profiler worker has a chance to start up. Once the worker is ready, call
`stopLoggingProfilerEvents` to return the log up to that point, then
send the array buffer to the worker.
Then switch to the sampling based approach.
* Record the current run ID
Each synchronous block of Scheduler work is given a unique run ID. This
is different than a task ID because a single task will have more than
one run if it yields with a continuation.
Provides partial support for React.lazy() components from the existing PartialRenderer server-side renderer.
Lazy components which are already resolved (or rejected), perhaps with something like `react-ssr-prepass`, can be continued into synchronously. If they have not yet been initialized, they'll be initialized before checking, opening the possibility to exploit this capability with a babel transform. If they're pending (which will typically be the case for a just initialized async ctor) then the existing invariant continues to be thrown.
* 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.
