Question: tracing

[revitteth]

Tracing appears to be a highly useful but delicate area of the client ecosystem, would it be possible to add some tracing to the fuzzer?

[holiman]

Well... The fuzzer is really based on tracing, not sure exactly what you mean. After the fuzzer finds an interesting case, it emits the trace-files, which can be investigated manually (or by tracediff/traceview). Don't know what else to do .. ?

[revitteth]

Sure, sorry I think I've got some specific cases which we could include which may show some issues tracing transactions/blocks with specific properties.

For example this tx on etherscan (state change tab shows no data): https://etherscan.io/tx/0x2fdf04a1d70c3cfa1f9d89baf080377ca110c5dbc28def63b01e18b270e85f6f#statechange

There is a full discussion here: erigontech/erigon#5306 and it looks like this potentially affects multiple clients.
