Problem

The gas and gasUsed fields in Geth Debug Trace root should be the gas limit and gas used for the entire transaction.

However, two fields in Parity Trace root should be the original ones.

Reproducible Example

With the latest version Reth v1.0.3, using trace_transaction() to trace
the transaction 0x03128677ee3a9623d20f3c677f423ccc592d126374bf32e331343dd1bdf38b61

curl http:https://localhost:8545 \
  -X POST \
  -H "Content-Type: application/json" \
  --data '{"method":"trace_transaction","params":["0x03128677ee3a9623d20f3c677f423ccc592d126374bf32e331343dd1bdf38b61"],"id":1,"jsonrpc":"2.0"}'  

From Reth

gas: 0x55493 (349331)
gasUsed: 0x32d16 (208150)

From Etherscan and QuickNode

gas: 0x4f227 (324135)
gasUsed: 0x36622 (222754)

Solution for revm-inspectors

1. Not modify gas_limit and gas_used in the trace root

   - gas_limit = context.env.tx.gas_limit;
   - trace.set_root_trace_gas_used(gas_used);
   - trace.gas_used = gas_used(context.spec_id(), gas.spent(), gas.refunded() as u64);

2. The modification in Step 1 will cause another problem

   The gas field for Geth Debug Trace root will also be reset (not the gas limitation for the entire transaction).

   therefore, can define set_transaction_gas_limit() and with_transaction_gas_limit() for Geth Debug,

   which is similar to current set_transaction_gas_used() and with_transaction_gas_used() for Parity.

3. Then, modify the Reth Part:

   crates/rpc/rpc/src/trace.rs and crates/rpc/rpc/src/debug.rs to completely fix the bug.

Miscellaneous

• Actually, I love the current design, but the results are inconsistent with those of others.

• When I used make pr to test the Reth Part, the issue make pr failed of lockfile reth#9381 still exists for me.

  I should only skip tests for lockfile and test them seperately.

tysm for looking into this.

it seems like this is still a wip and I'll take a closer look once cleaned up.
but very supportive, your write up made a lot of sense

[mattsse]

ty!
last question

[mattsse]

this got lost, or do we no longer need this?

[DaniPopes]

Unused, we also have unused variables in the various constructors

[ZzPoLariszZ]

I double check the code. This is self.spec_id for TracingInspector is used to set the gas limit for the Parity trace root only once. For Geth Debug trace, this will be set in the newly constructed functions set_transaction_gas_limit() and with_transaction_gas_limit(). Therefore, we on longer need this.

[mattsse]

tysm!

doing a new release and we can finish the reth pr
