Functions

func KeyToRegisterID

func KeyToRegisterID(key ledger.Key) (flow.RegisterID, error)

func NewView

func NewView(payloads []ledger.Payload) *view

func NoOpMigration

func NoOpMigration(p []ledger.Payload) ([]ledger.Payload, error)

func PruneMigration

func PruneMigration(payload []ledger.Payload) ([]ledger.Payload, error)

PruneMigration removes all the payloads with empty value this prunes the trie for values that has been deleted

func StorageFeesMigration

func StorageFeesMigration(payload []ledger.Payload) ([]ledger.Payload, error)

iterates through registers keeping a map of register sizes after it has reached the end it add storage used and storage capacity for each address

Types

type AccountStatusMigration

type AccountStatusMigration struct {
	Logger zerolog.Logger
}

AccountStatusMigration migrates previous registers under key of Exists which were used for checking existance of accounts. the new register AccountStatus also captures frozen and all future states of the accounts. Frozen state is used when an account is set by the network governance for furture investigation and prevents operations on the account until furthure investigation by the community. This migration assumes no account has been frozen until now, and would warn if find any account with frozen flags.

func (*AccountStatusMigration) Migrate

func (as *AccountStatusMigration) Migrate(payload []ledger.Payload) ([]ledger.Payload, error)

type AccountsAtreeLedger

type AccountsAtreeLedger struct {
	Accounts fvmState.Accounts
}

func NewAccountsAtreeLedger

func NewAccountsAtreeLedger(accounts fvmState.Accounts) *AccountsAtreeLedger

func (*AccountsAtreeLedger) AllocateStorageIndex

func (a *AccountsAtreeLedger) AllocateStorageIndex(owner []byte) (atree.StorageIndex, error)

AllocateStorageIndex allocates new storage index under the owner accounts to store a new register

func (*AccountsAtreeLedger) GetValue

func (a *AccountsAtreeLedger) GetValue(owner, key []byte) ([]byte, error)

func (*AccountsAtreeLedger) SetValue

func (a *AccountsAtreeLedger) SetValue(owner, key, value []byte) error

func (*AccountsAtreeLedger) ValueExists

func (a *AccountsAtreeLedger) ValueExists(owner, key []byte) (exists bool, err error)

type LegacyControllerMigration

type LegacyControllerMigration struct {
	Logger zerolog.Logger
}

LegacyControllerMigration migrates previous registers that were using the legacy controller value (value is always set to the same owner value). the controller value should now all be empty and in future can be remove all together.

func (*LegacyControllerMigration) Migrate

func (lc *LegacyControllerMigration) Migrate(payload []ledger.Payload) ([]ledger.Payload, error)

type StorageUsedUpdateMigration

type StorageUsedUpdateMigration struct {
	Log       zerolog.Logger
	OutputDir string
}

func (*StorageUsedUpdateMigration) Migrate

func (m *StorageUsedUpdateMigration) Migrate(payload []ledger.Payload) ([]ledger.Payload, error)

iterates through registers keeping a map of register sizes after it has reached the end it add storage used and storage capacity for each address
