README

state tool

This tool allows to rerun a set of batches, you could set a flag to persist changes in hashDB

Usage

Network configuration

If you want to avoid passing network configuration (--network and --custom-network-file) you need to provide the L2ChainID (--l2_chain_id)

Reprocess a set of batches and compare with state database

This reexecute a batch/batches and check if match the data on DB. It have some flags to allow:

  • --write_on_hash_db: this for each execution create the corresponding MT if possible it override state_db
  • --fist_batch: first batch to process (default: 1)
  • --last_batch: last batch to process (default: the highest batch on batch table)
  • --l2_chain_id: Instead of asking to SMC you can set it
  • --dont_stop_on_error: If a batch have an error the process doesn't stop
  • --prefer_execution_state_root: The oldStateRoot used to process a batch is usually is the stateRoot of the previous batch on database but, with this flag, you could use the calculated stateRoot from the execution result from previous batch instead

To see the full flags execute:

go run ./tools/state/. reprocess 

Examples:

  • You need to set the right State config, Executor config and MTClient. You can override the parameters with environment variables:
KEVM_NODE_MTCLIENT_URI="127.0.0.1:50061" ZKEVM_NODE_STATE_DB_HOST="127.0.0.1" ZKEVM_NODE_EXECUTOR_URI="127.0.0.1:50071" go run ./tools/state/. reprocess -cfg test/config/test.node.config.toml   -l2_chain_id 1440 --last_batch_number 5000
  • We are setting the chain_id directly so we don't need the genesis data.
  • All this examples redirect the log info to /dev/null for that reason if the command returns an error ($? -ne 1) relaunch without the redirection part (2> /dev/null) to see the full output
Rebuild hashdb entries for first 5000 batches
go run ./tools/state/. reprocess -cfg test/config/test.node.config.toml   -l2_chain_id 1440 --last_batch_number 5000 --write_on_hash_db 2> /dev/null

expected output:

Check that the batches from 1000 to 5000 match stateRoot
