Types

type ClientHooks

type ClientHooks interface {
	AfterHeaderWithValidCommit(ctx sdk.Context, txHash []byte, header *HeaderInfo, isOnFork bool)
}

ClientHooks defines the hook interface for client

type ExtendedKeeper

type ExtendedKeeper struct {
	clientkeeper.Keeper
	// contains filtered or unexported fields
}

ExtendedKeeper is same as the original clientkeeper.Keeper, except that

• it provides hooks for notifying other modules on received headers
• it applies different verification rules on received headers (notably, intercepting headers rather than freezing clients upon errors that indicate dishonest majority)

func NewExtendedKeeper

func NewExtendedKeeper(cdc codec.BinaryCodec, key storetypes.StoreKey, paramSpace paramtypes.Subspace, sk types.StakingKeeper, uk types.UpgradeKeeper) ExtendedKeeper

NewExtendedKeeper creates a new NewExtendedKeeper instance

func (ExtendedKeeper) AfterHeaderWithValidCommit

func (ek ExtendedKeeper) AfterHeaderWithValidCommit(ctx sdk.Context, txHash []byte, header *HeaderInfo, isOnFork bool)

func (*ExtendedKeeper) SetHooks

func (ek *ExtendedKeeper) SetHooks(ch ClientHooks) *ExtendedKeeper

SetHooks sets the hooks for ExtendedKeeper

func (ExtendedKeeper) UpdateClient

func (k ExtendedKeeper) UpdateClient(ctx sdk.Context, clientID string, clientMsg exported.ClientMessage) error

UpdateClient updates the consensus state and the state root from a provided header. The implementation is the same as the original IBC-Go implementation, except from: 1. Not freezing the client when finding a misbehaviour for header message 2. Calling a AfterHeaderWithValidCommit callback when receiving valid header messages (either misbehaving or not)

type HeaderInfo

type HeaderInfo struct {
	Hash     []byte
	ChaindId string
	Height   uint64
}

func GetHeaderInfo

func GetHeaderInfo(ctx sdk.Context, m exported.ClientMessage) *HeaderInfo

GetHeaderInfo returns the information necessary for header timestamping or nil if provided message is not a header

type MultiClientHooks

type MultiClientHooks []ClientHooks

func NewMultiClientHooks

func NewMultiClientHooks(hooks ...ClientHooks) MultiClientHooks

func (MultiClientHooks) AfterHeaderWithValidCommit

func (h MultiClientHooks) AfterHeaderWithValidCommit(ctx sdk.Context, txHash []byte, header *HeaderInfo, isOnFork bool)

invoke hooks in each keeper that hooks onto ExtendedKeeper
