t8n is supposed to produce vmtrace files in out directory
Trace file `trace-0-0xeda4d6763740fbccc99cc8873ff09b8504d192e83f73bd16ccf5feb053a4e3cd.jsonl` not found!
WARNING: Transaction trace not found! (0xeda4d6763740fbccc99cc8873ff09b8504d192e83f73bd16ccf5feb053a4e3cd)
trace-[txIndex]-[txHash].jsonl
t8n trace options:
--trace (default: false)
Output full trace logs to files <txhash>.jsonl
--trace.memory (default: false)
Enable full memory dump in traces
--trace.nomemory (default: true)
Disable full memory dump in traces (deprecated)
--trace.noreturndata (default: true)
Disable return data output in traces (deprecated)
--trace.nostack (default: false)
Disable stack output in traces
--trace.returndata (default: false)
Enable return data output in traces
the trace format must be exactly the same as of issue: ethereum/tests#249
but better to compare to the outputs produced by geth.
if we have the same trace format we can use tools to find transaction execution bugs
