Have we observed unexpected/harmful behaviour from this call? I'm leaning towards "if it ain't broke don't fix" without the context
No, because we have a checks inside both The main reason why I am removing it here, because we shouldn't be storing profiling settings in Agent, we can skip this step and just pass it from Hook -> Renderer. This is what is implemented in #31132. |
Stacked on #31131. See last commit. This is a clean-up and a pre-requisite for next changes: 1. `ReloadAndProfileConfig` is now split into boolean value and settings object. This is mainly because I will add one more setting soon, and also because settings might be persisted for a longer time than the flag which signals if the Backend was reloaded for profiling. Ideally, this settings should probably be moved to the global Hook object, same as we did for console patching. 2. Host is now responsible for reseting the cached values, Backend will execute provided `onReloadAndProfileFlagsReset` callback.

Stacked on #31118. See last commit.
We don't need to call
startProfiling()
here, because we delegate this to the Renderer itself:react/packages/react-devtools-shared/src/backend/fiber/renderer.js
Lines 5227 to 5232 in 830e823
Since this is de-facto the constructor of Renderer, this will be called earlier.
Validated via testing the reload-to-profile for Chrome browser extension.
