Functions

func AddMissingKeysMigration

func AddMissingKeysMigration(payloads []ledger.Payload) ([]ledger.Payload, error)

func MultipleContractMigration

func MultipleContractMigration(payloads []ledger.Payload) ([]ledger.Payload, error)

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

func StorageFormatV4Migration

func StorageFormatV4Migration(payloads []ledger.Payload) ([]ledger.Payload, error)

Types

type BalanceReporter

type BalanceReporter struct {
	Log       zerolog.Logger
	OutputDir string
	// contains filtered or unexported fields
}

BalanceReporter iterates through registers getting the location and balance of all FlowVaults

func (*BalanceReporter) Report

func (r *BalanceReporter) Report(payload []ledger.Payload) error

Report creates a balance_report_*.json file that contains data on all FlowVaults in the state commitment. I recommend using gojq to browse through the data, because of the large uint64 numbers which jq won't be able to handle.

type ContractReporter

type ContractReporter struct {
	Log       zerolog.Logger
	OutputDir string
}

reports on which contracts are deployed

func (ContractReporter) Report

func (r ContractReporter) Report(payload []ledger.Payload) error

type EmptyContainerTypeInferringError

type EmptyContainerTypeInferringError struct {
}

func (EmptyContainerTypeInferringError) Error

func (e EmptyContainerTypeInferringError) Error() string

type MultipleContractMigrationError

type MultipleContractMigrationError struct {
	Errors []error
}

func (*MultipleContractMigrationError) Error

func (e *MultipleContractMigrationError) Error() string

type StorageFormatV5Migration

type StorageFormatV5Migration struct {
	Log       zerolog.Logger
	OutputDir string

	CleanupStorage bool
	// contains filtered or unexported fields
}

func (*StorageFormatV5Migration) Migrate

func (m *StorageFormatV5Migration) Migrate(payloads []ledger.Payload) ([]ledger.Payload, error)

type StorageReporter

type StorageReporter struct {
	Log       zerolog.Logger
	OutputDir string
}

iterates through registers keeping a map of register sizes reports on storage metrics

func (StorageReporter) Report

func (r StorageReporter) Report(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
