Functions ¶
func CheckStateTree ¶
func CheckStateTree(ctx context.Context, store cbor.IpldStore, root cid.Cid, priorEpoch abi.ChainEpoch, expectedBalanceTotal abi.TokenAmount) error
Checks that a state tree is internally consistent. This performs only very basic checks. Versions in v2 will be much more thorough.
func MigrateStateTree ¶
func MigrateStateTree(ctx context.Context, store cbor.IpldStore, root cid.Cid, priorEpoch abi.ChainEpoch) (cid.Cid, error)
Loads and migrates the Filecoin state tree from a root, writing the new state tree blocks into the same store. Returns the new root of the state tree.
Types ¶
type StateMigration ¶
type StateMigration interface {
// Loads an actor's state from an input store at `head` and writes new state to an output store.
// The migration is assumed to be running after the end of `priorEpoch` (the epoch can affect the migration logic).
// The actor's address is `addr` and the state `tree` provides access to other actor states.
// Returns the new state head CID.
MigrateState(ctx context.Context, store cbor.IpldStore, head cid.Cid, priorEpoch abi.ChainEpoch, addr address.Address, tree *states.Tree) (newHead cid.Cid, err error)
}
