I rationalized it because it would be a React bug if it ever happened, so it shouldn't happen. But yea it shouldn't happen conditionally even then. I'll change it.

Why do you check currentTaskInDEV before reading from task?

This looks like a mistake. You're assigning task.componentStack = task.componentStack

Oops. Yea. Looks like I should add a test that tests component stacks when there's a suspended boundary inbetween.

The Flight server renderer is more complicated because it uses JSON.stringify so we don't have access to what happens on the stack. We'd have to reimplement that for DEV or perhaps which technique in both PROD/DEV. There are context related reasons we might want to switch implementation away from JSON.stringify for that reason. |
Right 😬 but we will need something similar for DevTools. Right now, Flight server doesn't track either owner or parent. |
This uses a reverse linked list in DEV-only to keep track of where we're currently executing.
This makes it more explicit which stack we pass in to be retained by the task.

This one is fun. We can probably port it to make it work with async functions too.

This uses a reverse linked list in DEV-only to keep track of where we're currently executing. It works similar to context in that it saves these on the running task.
In addition to this we need access to the current task to extract it. We could keep it only the "current component stack" but we still need to be able to stash it on the task occasionally.
This causes a bit of an awkwardness where current task is available and also the task is passed as an argument to all current functions.
Note that I wasn't planning on using this for production stacks. We don't invoke error boundaries anyway but we could pass stacks to the global callback. But this seems a bit heavy just for that. A variant of this would be to use the plain stack but that doesn't carry along the stack between tasks. A compromise could be to only collect the stack on the current running stack. This is effectively what happens with Promises in production since async boundaries aren't tracked there.
