Functions ¶
func CommitDelta ¶
func CommitDelta(ldg ledger.Ledger, ruh RegisterUpdatesHolder, baseState flow.StateCommitment) (flow.StateCommitment, *ledger.TrieUpdate, error)
func IsBlockExecuted ¶
func IsBlockExecuted(ctx context.Context, state ReadOnlyExecutionState, block flow.Identifier) (bool, error)
IsBlockExecuted returns whether the block has been executed. it checks whether the state commitment exists in execution state.
func LedgerGetRegister ¶
func LedgerGetRegister(ldg ledger.Ledger, commitment flow.StateCommitment) delta.GetRegisterFunc
func RegisterIDSToKeys ¶
func RegisterIDSToKeys(ids []flow.RegisterID) []ledger.Key
func RegisterIDToKey ¶
func RegisterIDToKey(reg flow.RegisterID) ledger.Key
func RegisterValuesToValues ¶
func RegisterValuesToValues(values []flow.RegisterValue) []ledger.Value
Types ¶
type ExecutionState ¶
type ExecutionState interface {
ReadOnlyExecutionState
UpdateHighestExecutedBlockIfHigher(context.Context, *flow.Header) error
SaveExecutionResults(ctx context.Context, header *flow.Header, endState flow.StateCommitment,
chunkDataPacks []*flow.ChunkDataPack,
executionReceipt *flow.ExecutionReceipt, events []flow.EventsList, serviceEvents flow.EventsList, results []flow.TransactionResult) error
}
ExecutionState is an interface used to access and mutate the execution state of the blockchain.
func NewExecutionState ¶
func NewExecutionState( ls ledger.Ledger, commits storage.Commits, blocks storage.Blocks, headers storage.Headers, collections storage.Collections, chunkDataPacks storage.ChunkDataPacks, results storage.ExecutionResults, myReceipts storage.MyExecutionReceipts, events storage.Events, serviceEvents storage.ServiceEvents, transactionResults storage.TransactionResults, db *badger.DB, tracer module.Tracer, ) ExecutionState
NewExecutionState returns a new execution state access layer for the given ledger storage.
type ReadOnlyExecutionState ¶
type ReadOnlyExecutionState interface {
// NewView creates a new ready-only view at the given state commitment.
NewView(flow.StateCommitment) *delta.View
GetRegisters(
context.Context,
flow.StateCommitment,
[]flow.RegisterID,
) ([]flow.RegisterValue, error)
GetProof(
context.Context,
flow.StateCommitment,
[]flow.RegisterID,
) (flow.StorageProof, error)
// StateCommitmentByBlockID returns the final state commitment for the provided block ID.
StateCommitmentByBlockID(context.Context, flow.Identifier) (flow.StateCommitment, error)
// HasState returns true if the state with the given state commitment exists in memory
HasState(flow.StateCommitment) bool
// ChunkDataPackByChunkID retrieve a chunk data pack given the chunk ID.
ChunkDataPackByChunkID(flow.Identifier) (*flow.ChunkDataPack, error)
GetExecutionResultID(context.Context, flow.Identifier) (flow.Identifier, error)
RetrieveStateDelta(context.Context, flow.Identifier) (*messages.ExecutionStateDelta, error)
GetHighestExecutedBlockID(context.Context) (uint64, flow.Identifier, error)
GetCollection(identifier flow.Identifier) (*flow.Collection, error)
GetBlockIDByChunkID(chunkID flow.Identifier) (flow.Identifier, error)
}
ReadOnlyExecutionState allows to read the execution state
type RegisterUpdatesHolder ¶
type RegisterUpdatesHolder interface {
RegisterUpdates() ([]flow.RegisterID, []flow.RegisterValue)
}
