Doesn't this also trigger for a regular create-transaction?

Do you need to declare this function here? Wouldn't this defeat the purpose of not having to call back into js for every step?

Ooof! I need to rerun the benches now!

Turns out the speedup is much more, it's only that I had forgotten to remove |

* eth/tracers: implement debug.intermediateRoots (ethereum#23594) This PR implements a new debug method, which I've talked briefly about to some other client developers. It allows the caller to obtain the intermediate state roots for a block (which might be either a canon block or a 'bad' block).

Due to how the reference counting works within the trie database (where parent count is recursively updated when new parents are added), doing dereferencing in the middle of Commit can cause the refcount to become wrong, leading to an inconsistent state. This was fixed by doing Commit/Deref from the same routine. Signed-off-by: wenbiao <delweng@gmail.com> * core,eth: call frame tracing (ethereum#23087) This change introduces 2 new optional methods; `enter()` and `exit()` for js tracers, and makes `step()` optiona. The two new methods are invoked when entering and exiting a call frame (but not invoked for the outermost scope, which has it's own methods). Currently these are the data fields passed to each of them: enter: type (opcode), from, to, input, gas, value exit: output, gasUsed, error The PR also comes with a re-write of the callTracer. As a backup we keep the previous tracing script under the name `callTracerLegacy`. Behaviour of both tracers are equivalent for the most part, although there are some small differences (improvements), where the new tracer is more correct / has more information.

Introduces 2 new optional methods
enter()andexit()for js tracers which are invoked on stepping in and out a call frame. These methods are not invoked for depth 0. Currently these are the data fields passed to each of them:If these methods are not present in the JS script geth will default to only invoking
step(). On the other hand, you have the option of only providingenter()andexit(), and not providingstep()if call frames are the only thing you care about. This should yield a ~5x tracing speedup because it avoids the go-js barrier on every opcode.The PR also comes with a re-write of the
callTracer. As a backup we keep the previous tracing script under the namecallTracerLegacy. Behaviour of both tracers are equivalent for the most part, although there are some small differences (improvements):CALL*/CREATE*fails without having executed any code, i.e. in the initial conditions like whether sender has enough balance, then no call frame will be recorded.gasandgasUsedvalues are set to0instead ofnilwhere they are unavailable.
