func AssertDBConsistency ¶

func AssertDBConsistency(t testing.TB, root common.Hash, clientDB ethdb.Database, serverTrieDB, clientTrieDB *triedb.Database)

AssertDBConsistency checks [serverTrieDB] and [clientTrieDB] have the same EVM state trie at [root], and that [clientTrieDB.DiskDB] has corresponding account & snapshot values. Also verifies any code referenced by the EVM state is present in [clientTrieDB] and the hash is correct.

func AssertTrieConsistency ¶

func AssertTrieConsistency(t testing.TB, root common.Hash, a, b *triedb.Database, onLeaf func(key, val []byte) error)

AssertTrieConsistency ensures given trieDB [a] and [b] both have the same non-empty trie at [root]. (all key/value pairs must be equal)

func CorruptTrie ¶

func CorruptTrie(t *testing.T, diskdb ethdb.Batcher, tr *trie.Trie, n int)

CorruptTrie deletes every [n]th trie node from the trie given by [tr] from the underlying [db]. Assumes [tr] can be iterated without issue.

func FillAccounts ¶

func FillAccounts(
	t *testing.T, r *rand.Rand, trieDB *triedb.Database, root common.Hash, numAccounts int,
	onAccount func(*testing.T, int, types.StateAccount) types.StateAccount,
) (common.Hash, map[*utilstest.Key]*types.StateAccount)

FillAccounts adds [numAccounts] randomly generated accounts to the secure trie at [root] and commits it to [trieDB]. [onAccount] is called if non-nil (so the caller can modify the account before it is stored in the secure trie). returns the new trie root and a map of funded keys to StateAccount structs.

func FillAccountsWithOverlappingStorage ¶

func FillAccountsWithOverlappingStorage(
	t *testing.T, r *rand.Rand, trieDB *triedb.Database, root common.Hash, numAccounts int, numOverlappingStorageRoots int,
) (common.Hash, map[*utilstest.Key]*types.StateAccount)

FillAccountsWithOverlappingStorage adds [numAccounts] randomly generated accounts to the secure trie at [root] and commits it to [trieDB]. For each 3 accounts created: - One does not have a storage trie, - One has a storage trie shared with other accounts (total number of shared storage tries [numOverlappingStorageRoots]), - One has a uniquely generated storage trie, returns the new trie root and a map of funded keys to StateAccount structs.

func FillAccountsWithStorage ¶

func FillAccountsWithStorage(t *testing.T, r *rand.Rand, serverDB ethdb.Database, serverTrieDB *triedb.Database, root common.Hash, numAccounts int) common.Hash

func FillTrie ¶

func FillTrie(t *testing.T, r *rand.Rand, start, numKeys int, keySize int, trieDB *triedb.Database, root common.Hash) (common.Hash, [][]byte, [][]byte)

FillTrie fills a given trie with [numKeys] random keys, each of size [keySize] returns inserted keys and values

func GenerateTrie ¶

func GenerateTrie(t *testing.T, r *rand.Rand, trieDB *triedb.Database, numKeys int, keySize int) (common.Hash, [][]byte, [][]byte)

GenerateTrie creates a trie with [numKeys] random key-value pairs inside of [trieDB]. Returns the root of the generated trie, the slice of keys inserted into the trie in lexicographical order, and the slice of corresponding values.
