Stacked on #30174. This tracks the current debugTask on the Task so that when an error is thrown we can use it to run the `onError` (and `onShellError` and `onFatalError`) callbacks within the Context of that task. Ideally it would be associated with the error object but neither console.error [nor reportError](https://crbug.com/350426235) reports this as the async stack so we have to manually restore it. That way when you inspect Fizz using node `--inspect` we show the right async stack. <img width="616" alt="Screenshot 2024-07-01 at 10 52 29 PM" src="https://github.com/facebook/react/assets/63648/db68133e-124e-4509-8241-c67160db94fc"> This is equivalent to how we track the task that created the parent server component or the Fiber: https://github.com/facebook/react/blob/311d569412d2621102f31074e27a3981f4237c6b/packages/react-reconciler/src/ReactChildFiber.js#L1985 Then use them when invoking the error callbacks: https://github.com/facebook/react/blob/311d569412d2621102f31074e27a3981f4237c6b/packages/react-reconciler/src/ReactFiberThrow.js#L104-L108 --------- Co-authored-by: Sebastian Silbermann <[email protected]>
react-server
This is an experimental package for creating custom React streaming server renderers.
Its API is not as stable as that of React, React Native, or React DOM, and does not follow the common versioning scheme.
Use it at your own risk.
