`persist` is a hotspot when processing blocks because it is run at least once per transaction and loops over the entire account cache every time. Here, we introduce an extra `dirty` map that keeps track of all accounts that need checking during `persist` which fixes the immediate inefficiency, though probably this could benefit from a more thorough review - we also get rid of the unused clearCache flag - we start with a fresh cache on every fresh vmState. * avoid unnecessary code hash comparisons * avoid unnecessary copies when iterating * use EMPTY_CODE_HASH throughout for code hash comparison
EVM state test tool
The evmstate tool to execute state test.
Build instructions
There are few options to build evmstate tool like any other nimbus tools.
- Use your system Nim compiler(v1.6.12) and git to install dependencies.
$> git submodule update --init --recursive $> ./env.sh (run once to generate nimbus-build-system.paths) $> nim c -d:release tools/evmstate/evmstate $> nim c -r -d:release tools/evmstate/evmstate_test - Use nimbus shipped Nim compiler and dependencies.
$> make update deps $> ./env.sh nim c -d:release tools/evmstate/evmstate $> ./env.sh nim c -r -d:release tools/evmstate/evmstate_test - Use nimbus makefile.
$> make update $> make evmstate $> make evmstate_test

evmstate [OPTIONS]... <inputFile>
<inputFile> json file contains state test data.
The following options are available:
--dump dumps the state after the run [=false].
--json output trace logs in machine readable format (json) [=false].
--debug output full trace logs [=false].
--nomemory disable memory output [=true].
--nostack disable stack output [=false].
--nostorage disable storage output [=false].
--noreturndata enable return data output [=true].
--fork choose which fork to be tested.
--index if index is unset, all subtest in the fork will be tested [=none(int)].
--pretty pretty print the trace result [=false].
--verbosity sets the verbosity level [=0].
0 = silent, 1 = error, 2 = warn, 3 = info, 4 = debug, 5 = detail.
