Functions

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 NewMainTrieTask

func NewMainTrieTask(sync *stateSync) syncTask

func NewStateSyncer

func NewStateSyncer(config *StateSyncerConfig) (*stateSync, error)

func NewStorageTrieTask

func NewStorageTrieTask(sync *stateSync, root common.Hash, accounts []common.Hash) syncTask

func NewTrieQueue

func NewTrieQueue(db ethdb.Database) *trieQueue

func NewTrieToSync

func NewTrieToSync(sync *stateSync, root common.Hash, account common.Hash, syncTask syncTask) (*trieToSync, error)

NewTrieToSync initializes a trieToSync and restores any previously started segments.

Types

type CodeSyncerConfig

type CodeSyncerConfig struct {
	// Maximum number of outstanding code hashes in the queue before the code syncer should block.
	MaxOutstandingCodeHashes int
	// Number of worker threads to fetch code from the network
	NumCodeFetchingWorkers int

	// Client for fetching code from the network
	Client statesyncclient.Client

	// Database for the code syncer to use.
	DB ethdb.Database
}

CodeSyncerConfig defines the configuration of the code syncer

type StateSyncerConfig

type StateSyncerConfig struct {
	Root                     common.Hash
	Client                   syncclient.Client
	DB                       ethdb.Database
	BatchSize                int
	MaxOutstandingCodeHashes int    // Maximum number of code hashes in the code syncer queue
	NumCodeFetchingWorkers   int    // Number of code syncing threads
	RequestSize              uint16 // Number of leafs to request from a peer at a time
