Add debug logs for provider creation #5478

Closed fvictorio closed 1 day ago

fvictorio commented 2 days ago

Now and then, there are some timeouts in EDR Hardhat tests (example) related to the provider initialization in a beforeEach hook.

This seems super weird to me. That before each only has two async operations: a call to createHardhatNetworkProvider and a server.listen() call a bit below that. I'm completely sure that the alchemy provider (which is the one with the timeout) doesn't use the server, so the only async operation is the provider creation.

But createHardhatNetworkProvider is async just because it calls the makeTracingConfig function, which loads some build info files. I doubt that this is the function that is causing a 50s timeout, so the alternative is that there's something weird going on now and then with EdrProviderWrapper.create.

The easiest way to evaluate this theory is to add some debug logs, and to add DEBUG="hardhat:core:hardhat-network:*" in EDR's CI. This won't produce any results until a new version of Hardhat is released and a new timeout is hit (it doesn't happen often), but this is not urgent so this is fine.
