Actually, while I think this change is correct and good, I don't think 'lingering' evm executions can happen. The RPC call will only ever return once the evm execution is finished. |

* 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.

This PR tries to fix #23397. Geth goes OOM after
heavy transaction tracing.
The tracer has a
Stopmethod, which sets a flag. This flag causes the tracer to stop doing work, as in no longer invokingthe javascript engine for each opcode. However, it does not actually stop the evm execution.
I tested with a little
traceCallwhere we just run in a loop, burning 10M gas:If I run this on
master, with some added printout when the trace ends:So even if we call
Stop()after ~1ms, it takes ~40ms for the execution to complete.Whereas running it on this PR (with the added printout):
With the call to
env.Cancel, theevmactually aborts after max1000more steps. If the cause of the OOMs arelingering evm executions piling up, then this PR should fix it (or at least make it a lot more robust).
