There are now 3 "db hash" variants to choose for a test:
VerifyDBHash
works as before: calculates a hash of the low-level DB contents (including the whole trie, all states, blocks, etc).VerifyStateHash
calculates a hash of the whole chain state at the latest state index.VerifyContractStateHash
calculates a hash of the state of a single core contract, at the latest state index. An optional prefix can be supplied to verify just a subset of the keys in the state.There is also a new
DB_DUMP
environment variable that can be used to store a hex dump of the DB contents, and later compute a diff between two different branches.
