I moved unstable_SuspenseList internally. We don't need the FB build.
I plan on also removing the ReactDOM fb specific entry. We shouldn't add
any more FB specific internals nor APIs. If they're experimental they
should go onto the experimental builds to avoid too many permutations.
* Remove renderPhaseUpdates Map
Follow up to #17484, which was reverted due to a bug found in www.
* Failing test: Dropped updates
When resetting render phase updates after a throw, we should only clear
the pending queue of hooks that were already processed.
* Fix non-render-phase updates being dropped
Detects if a queue has been processed by whether the hook was cloned.
If we change the implementation to an array instead of a list, we'll
need some other mechanism to determine whether the hook was processed.
* Regression test: startTransition in render phase
useTransition uses the state hook as part of its implementation, so we
need to fork it in the dispatcher used for re-renders, too.
* Update Flow to 0.84
* Fix violations
* Use inexact object syntax in files from fbsource
* Fix warning extraction to use a modern parser
* Codemod inexact objects to new syntax
* Tighten types that can be exact
* Revert unintentional formatting changes from codemod
* Remove toString of dangerouslySetInnerHTML
As far as I can tell, the toString call was added here:
https://github.com/facebook/react/commit/caae627cd557812d28d11237b34bff6c661ea8bc#diff-5574f655d491348f422bca600ff6711dR887
It was never really needed. Subsequently when we added Trusted Types,
this needed to be changed to a special call but we really should just
always let it pass through.
* Remove special casing of toString values when enableTrustedTypesIntegration
As far as I can tell, we only toString in user space because of IE8/9.
We don't really support IE8/9 anymore and by the time this flag is on,
we should be able to deprecate it.
Unless this is also an issue in IE11. I haven't tested yet.
* Revert "Revert "Dispatch commands to both UIManagers from both renderers (#17211)" (#17232)"
This reverts commit d0fc0ba0a6.
* Clean up another __DEV__ warning check
Previously, DevTools filtered empty commits on the backend, while profiling, through the use of a bailout heuristic that React currently happens to use. This approach was brittle and may have exacerbated the long-standing Profiler bug #16446.
This PR removes that heuristic and adds as a post-processing filtering pass instead. This removes the coupling between DevTools and a React internal implementation detail that may change.
I believe DevTools has two choices of criteria for this filtering:
* Filter commits that have no actual duration metadata.
* Filter commits that have no recorded operations (no mutations to the tree, no changed tree base durations).
I chose the first option, filtering by commits that have no reported metadata. It will miss an edge case, e.g. , but we would have nothing meaningful to show in the Profiler for those cases anyway. (This particular edge case is why one of the snapshots changed with this commit.)
The second option, filtering by recorded operations, could potentially miss a more important edge case: where a component *did* render, but its didn't change. (In that event, there would be no operations to send.)
stateNode is not one of the fields that gets copied over by createWorkInProgress.
This is bad for persistent mode since it's not the same instance.
In HostComponent we happened to always end up transferring the current stateNode when we bail.
However, we didn't do this for HostText.
DevTools previously called in several places with user-defined values. This could lead to runtime errors if those values had an overriden attribute. This commit replaces those callse with instead.
New test cases have been added.
The Profiler stores:
1. A snapshot of the React tree when profiling started
2. The operations array for each commit
3. Profiling metadata (e.g. durations, what changed, etc) for each commit
It uses this information (snapshot + operations diff) to reconstruct the state of the application for a given commit as it's viewed in the Profiler UI. Because of this, it's very important that the operations and metadata arrays align. If they don't align, the profiler will be unable to correctly reconstruct the tree, and it will likely throw errors (like 'Could not find node…')
#16446 tracks a long-standing bug where these two arrays get misaligned. I am still not entirely sure what causes this bug, but with PR #17253, I exacerbated things by introducing another potential way for it to happen. This PR addresses the regression at least (and adds test coverage for it).
I will follow up this afternoon on the original #16446 issue. I think I may have a lead on what's happening at least, if not exactly an idea of how to reproduce it.
I used to disable the <- and -> buttons when you reached the beginning or end of the profiler data. This can be kind of annoying though when you just want to get to the last commit, and I don't think there's a good reason to enforce it anyway, so I backed that change out. The buttons now wrap around at the beginning or end of the list.
