func CopyStorageSnapshot ¶

func CopyStorageSnapshot(db ethdb.Iteratee, account common.Hash, batch ethdb.Batch, batchSize int, dstAccounts []common.Hash) error

CopyStorageSnapshot iterates [db] to find all storage snapshot entries for [account] and copies them to the storage snapshot of each account in [dstAccounts] Note: assumes that the storage snapshot for [account] is already complete.

func FillAccounts ¶

func FillAccounts(
	t *testing.T, trieDB *trie.Database, root common.Hash, numAccounts int,
	onAccount func(*testing.T, int, types.StateAccount) types.StateAccount,
) (common.Hash, map[*keystore.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, trieDB *trie.Database, root common.Hash, numAccounts int, numOverlappingStorageRoots int,
) (common.Hash, map[*keystore.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 NewEVMStateSyncer ¶

func NewEVMStateSyncer(config *EVMStateSyncerConfig) (*stateSyncer, error)

func RestoreMainTrieProgressFromSnapshot ¶

func RestoreMainTrieProgressFromSnapshot(db ethdb.Iteratee, tr *TrieProgress) error

RestoreMainTrieProgressFromSnapshot iterates the account snapshots from [db] and adds full RLP representations as leafs to the stack trie in [tr]. Also sets [tr.startsFrom] to the key that syncing can begin from.

func RestoreStorageTrieProgressFromSnapshot ¶

func RestoreStorageTrieProgressFromSnapshot(db ethdb.Iteratee, tr *TrieProgress, account common.Hash) error

RestoreStorageTrieProgressFromSnapshot iterates the account storage snapshots for [account] from [db] and adds key/value pairs as leafs to the stack trie in [tr]. Also sets [tr.startsFrom] to the key that syncing can begin from.

func WriteAccountSnapshot ¶

func WriteAccountSnapshot(db ethdb.KeyValueWriter, accHash common.Hash, acc types.StateAccount)

WriteAccountSnapshot stores the account represented by [acc] to the snapshot at [accHash], using SlimAccountRLP format (omitting empty code/storage).

func WriteAccountStorageSnapshotFromTrie ¶

func WriteAccountStorageSnapshotFromTrie(batch ethdb.Batch, batchSize int, accountHash common.Hash, storageTrie *trie.Trie) error

WriteAccountStorageSnapshotFromTrie iterates the trie at [storageTrie] and copies all entries to the storage snapshot for [accountHash].
