func (Keeper) GetLastRegisteredQueryKey 

func (k Keeper) GetLastRegisteredQueryKey(ctx sdk.Context) uint64

func (Keeper) GetParams 

func (k Keeper) GetParams(ctx sdk.Context) (params types.Params)

GetParams get all parameters as types.Params

func (Keeper) GetQueryByID 

func (k Keeper) GetQueryByID(ctx sdk.Context, id uint64) (*types.RegisteredQuery, error)

func (Keeper) GetQueryResultByID 

func (k Keeper) GetQueryResultByID(ctx sdk.Context, id uint64) (*types.QueryResult, error)

GetQueryResultByID returns a QueryResult for query with id

func (Keeper) GetRegisteredQueries 

func (k Keeper) GetRegisteredQueries(ctx sdk.Context, req *types.QueryRegisteredQueriesRequest) (*types.QueryRegisteredQueriesResponse, error)

func (Keeper) GetTxQueriesToRemove added in v0.3.0 

func (k Keeper) GetTxQueriesToRemove(ctx sdk.Context, limit uint64) []uint64

GetTxQueriesToRemove retrieves the list of TX queries registered to be removed. Returns a slice with no more than limit entities or all entities if limit is 0.

func (Keeper) LastRemoteHeight 

func (k Keeper) LastRemoteHeight(goCtx context.Context, request *types.QueryLastRemoteHeight) (*types.QueryLastRemoteHeightResponse, error)

func (Keeper) Logger 

func (k Keeper) Logger(ctx sdk.Context) log.Logger

func (Keeper) MustPayOutDeposit 

func (k Keeper) MustPayOutDeposit(ctx sdk.Context, deposit sdk.Coins, sender sdk.AccAddress)

func (Keeper) Params 

func (k Keeper) Params(c context.Context, req *types.QueryParamsRequest) (*types.QueryParamsResponse, error)

func (Keeper) ProcessBlock 

func (k Keeper) ProcessBlock(ctx sdk.Context, queryOwner sdk.AccAddress, queryID uint64, clientID string, block *types.Block) error

ProcessBlock verifies headers and transaction in the block, and then passes the tx query result to the querying contract's sudo handler.

func (Keeper) QueryResult 

func (k Keeper) QueryResult(goCtx context.Context, request *types.QueryRegisteredQueryResultRequest) (*types.QueryRegisteredQueryResultResponse, error)

func (Keeper) RegisteredQueries 

func (k Keeper) RegisteredQueries(goCtx context.Context, req *types.QueryRegisteredQueriesRequest) (*types.QueryRegisteredQueriesResponse, error)

func (Keeper) RegisteredQuery 

func (k Keeper) RegisteredQuery(goCtx context.Context, request *types.QueryRegisteredQueryRequest) (*types.QueryRegisteredQueryResponse, error)

func (Keeper) RemoveQuery added in v0.3.0 

func (k Keeper) RemoveQuery(ctx sdk.Context, query *types.RegisteredQuery)

RemoveQuery removes the given query and relative result data from the store. For a KV query it deletes the *types.QueryResult stored by the query ID, for a TX query it stores the query ID to the list of queries to be removed so the ICQ module can remove the query hashes later.

func (Keeper) SaveKVQueryResult 

func (k Keeper) SaveKVQueryResult(ctx sdk.Context, queryID uint64, result *types.QueryResult) error

SaveKVQueryResult saves the result of the query and updates the query's local and remote heights of last result submission. The result's height must be greater than the current remote height of the last query result submission, otherwise operation fails.

func (Keeper) SaveQuery 

func (k Keeper) SaveQuery(ctx sdk.Context, query *types.RegisteredQuery) error

func (Keeper) SaveTransactionAsProcessed 

func (k Keeper) SaveTransactionAsProcessed(ctx sdk.Context, queryID uint64, txHash []byte)

SaveTransactionAsProcessed simply stores a key (SubmittedTxKey + bigEndianBytes(queryID) + tx_hash) with mock data. This key can be used to check whether a certain transaction was already submitted for a specific transaction query.

func (Keeper) SetLastRegisteredQueryKey 

func (k Keeper) SetLastRegisteredQueryKey(ctx sdk.Context, id uint64)

func (Keeper) SetParams 

func (k Keeper) SetParams(ctx sdk.Context, params types.Params)

SetParams set the params

func (Keeper) TxQueriesCleanup added in v0.3.0 

func (k Keeper) TxQueriesCleanup(ctx sdk.Context)

TxQueriesCleanup cleans the module store from obsolete registered TX queries and relative stored transaction hashes. Cleans up to params.TxQueryRemovalLimit hashes at a time or all the hashes if params.TxQueryRemovalLimit is 0.

func (Keeper) UpdateLastLocalHeight 

func (k Keeper) UpdateLastLocalHeight(ctx sdk.Context, queryID uint64, newLocalHeight uint64) error

func (Keeper) UpdateLastRemoteHeight 

func (k Keeper) UpdateLastRemoteHeight(ctx sdk.Context, queryID uint64, newRemoteHeight ibcclienttypes.Height) error

UpdateLastRemoteHeight updates the relative query's remote height of the last result submission. The height must be greater than the current remote height of the last query result submission, otherwise operation fails.

type TransactionVerifier added in v0.2.0 

type TransactionVerifier struct{}

func (TransactionVerifier) VerifyTransaction added in v0.2.0 

func (v TransactionVerifier) VerifyTransaction(
	header *tendermintLightClientTypes.Header,
	nextHeader *tendermintLightClientTypes.Header,
	tx *types.TxValue,
) error

VerifyTransaction verifies that some transaction is included in block, and the transaction was executed successfully. The function checks: * transaction is included in block - header.DataHash merkle root contains transactions hash; * transactions was executed successfully - transaction's responseDeliveryTx.Code == 0; * transaction's responseDeliveryTx is legitimate - nextHeaderLastResultsDataHash merkle root contains deterministicResponseDeliverTx(ResponseDeliveryTx).Bytes()

type TxQueryToRemove added in v0.3.0 

type TxQueryToRemove struct {
	// ID is the query ID.
	ID uint64
	// Hashes is the list of tx hashes previously submitted for the query. It can be either
	// the whole list of tx hashes of the query of only a part of them to fit removal limit.
	Hashes [][]byte
	// CompleteRemoval represents whether all tx hashes (true) of the query or only a part of
	// them (false) are collected in the Hashes field.
	CompleteRemoval bool
}

TxQueryToRemove contains data related to a single query listed for removal and needed in the removal process.

type Verifier added in v0.2.0 

type Verifier struct{}

func (Verifier) UnpackHeader added in v0.2.0 

func (v Verifier) UnpackHeader(any *codectypes.Any) (exported.Header, error)

func (Verifier) VerifyHeaders added in v0.2.0 

func (v Verifier) VerifyHeaders(ctx sdk.Context, clientKeeper clientkeeper.Keeper, clientID string, header exported.Header, nextHeader exported.Header) error

VerifyHeaders verify that headers are valid tendermint headers, checks them on validity by trying call ibcClient.UpdateClient(header) to update light client's consensus state and checks that they are sequential (tl;dr header.Height + 1 == nextHeader.Height)
