Overview

Deprecated.

Legacy types are defined below to aid in the migration of Tendermint consensus parameters from use of the now deprecated x/params modules to a new dedicated x/consensus module.

Application developers should ensure that they implement their upgrade handler correctly such that app.ConsensusParamsKeeper.Set() is called with the values returned by GetConsensusParams().

Example: 

baseAppLegacySS := app.ParamsKeeper.Subspace(baseapp.Paramspace).WithKeyTable(paramstypes.ConsensusParamsKeyTable())

app.UpgradeKeeper.SetUpgradeHandler(
	UpgradeName,
	func(ctx sdk.Context, plan upgradetypes.Plan, fromVM module.VersionMap) (module.VersionMap, error) {
		if cp := baseapp.GetConsensusParams(ctx, baseAppLegacySS); cp != nil {
			app.ConsensusParamsKeeper.Set(ctx, cp)
		} else {
			ctx.Logger().Info("warning: consensus parameters are undefined; skipping migration", "upgrade", UpgradeName)
		}

		return app.ModuleManager.RunMigrations(ctx, app.Configurator(), fromVM)
	},
)

Developers can also bypass the use of the legacy Params subspace and set the values to app.ConsensusParamsKeeper.Set() explicitly.

Note, for new chains this is not necessary as Tendermint's consensus parameters will automatically be set for you in InitChain.

Regardless of tx execution outcome, the ResponseCheckTx will contain relevant gas execution context.

- Unbonding (safety threshold) time: The block interval in which validators can be economically punished for misbehavior. Blocks in this interval must be auditable e.g. by the light client.

- Logical store snapshot interval: The block interval at which the underlying logical store database is persisted to disk, e.g. every 10000 heights. Blocks since the last IAVL snapshot must be available for replay on application restart.

- State sync snapshots: Blocks since the oldest available snapshot must be available for state sync nodes to catch up (oldest because a node may be restoring an old snapshot while a new snapshot was taken).

- Local (minRetainBlocks) config: Archive nodes may want to retain more or all blocks, e.g. via a local config option min-retain-blocks. There may also be a need to vary retention for other nodes, e.g. sentry nodes which do not need historical blocks.

func (*BaseApp) GetConsensusParams 

func (app *BaseApp) GetConsensusParams(ctx sdk.Context) *tmproto.ConsensusParams

Transactions can be modified, removed, or added by the application. Since the application maintains its own local mempool, it will ignore the transactions provided to it in RequestPrepareProposal. Instead, it will determine which transactions to return based on the mempool's semantics and the MaxTxBytes provided by the client's request.

Ref: https://github.com/cosmos/cosmos-sdk/blob/main/docs/architecture/adr-060-abci-1.0.md Ref: https://github.com/tendermint/tendermint/blob/main/spec/abci/abci%2B%2B_basic_concepts.md

func (*BaseApp) ProcessProposal added in v0.47.0 

func (app *BaseApp) ProcessProposal(req abci.RequestProcessProposal) (resp abci.ResponseProcessProposal)

ProcessProposal implements the ProcessProposal ABCI method and returns a ResponseProcessProposal object to the client. The ProcessProposal method is responsible for allowing execution of application-dependent work in a proposed block. Note, the application defines the exact implementation details of ProcessProposal. In general, the application must at the very least ensure that all transactions are valid. If all transactions are valid, then we inform Tendermint that the Status is ACCEPT. However, the application is also able to implement optimizations such as executing the entire proposed block immediately.

If a panic is detected during execution of an application's ProcessProposal handler, it will be recovered and we will reject the proposal.

Note:

- Step (2) is identical to the validation step performed in DefaultProcessProposal. It is very important that the same validation logic is used in both steps, and applications must ensure that this is the case in non-default handlers.

If any transaction fails to pass either condition, the proposal is rejected. Note that step (2) is identical to the validation step performed in DefaultPrepareProposal. It is very important that the same validation logic is used in both steps, and applications must ensure that this is the case in non-default handlers.

ProposalTxVerifier defines the interface that is implemented by BaseApp, that any custom ABCI PrepareProposal and ProcessProposal handler can use to verify a transaction.

type QueryServiceTestHelper added in v0.40.0 

type QueryServiceTestHelper struct {
	*GRPCQueryRouter
	Ctx sdk.Context
}

QueryServiceTestHelper provides a helper for making grpc query service rpc calls in unit tests. It implements both the grpc Server and ClientConn interfaces needed to register a query service server and create a query service client.

func NewQueryServerTestHelper added in v0.40.0 

func NewQueryServerTestHelper(ctx sdk.Context, interfaceRegistry types.InterfaceRegistry) *QueryServiceTestHelper

NewQueryServerTestHelper creates a new QueryServiceTestHelper that wraps the provided sdk.Context

func (*QueryServiceTestHelper) Invoke added in v0.40.0 

func (q *QueryServiceTestHelper) Invoke(_ gocontext.Context, method string, args, reply interface{}, _ ...grpc.CallOption) error

Invoke implements the grpc ClientConn.Invoke method

func (*QueryServiceTestHelper) NewStream added in v0.40.0 

func (q *QueryServiceTestHelper) NewStream(gocontext.Context, *grpc.StreamDesc, string, ...grpc.CallOption) (grpc.ClientStream, error)

NewStream implements the grpc ClientConn.NewStream method

type RecoveryHandler added in v0.40.0 

type RecoveryHandler func(recoveryObj interface{}) error

RecoveryHandler handles recovery() object. Return a non-nil error if recoveryObj was processed. Return nil if recoveryObj was not processed.

type StoreLoader 

type StoreLoader func(ms storetypes.CommitMultiStore) error

StoreLoader defines a customizable function to control how we load the CommitMultiStore from disk. This is useful for state migration, when loading a datastore written with an older version of the software. In particular, if a module changed the substore key name (or removed a substore) between two versions of the software.

type StreamingService added in v0.45.9 

type StreamingService interface {
	// Stream is the streaming service loop, awaits kv pairs and writes them to some destination stream or file
	Stream(wg *sync.WaitGroup) error
	// Listeners returns the streaming service's listeners for the BaseApp to register
	Listeners() map[store.StoreKey][]store.WriteListener
	// ABCIListener interface for hooking into the ABCI messages from inside the BaseApp
	ABCIListener
	// Closer interface
	io.Closer
}

StreamingService interface for registering WriteListeners with the BaseApp and updating the service with the ABCI messages using the hooks

type TxSelector added in v0.47.6 

type TxSelector interface {
	// SelectedTxs should return a copy of the selected transactions.
	SelectedTxs() [][]byte

	// Clear should clear the TxSelector, nulling out all relevant fields.
	Clear()

	// SelectTxForProposal should attempt to select a transaction for inclusion in
	// a proposal based on inclusion criteria defined by the TxSelector. It must
	// return <true> if the caller should halt the transaction selection loop
	// (typically over a mempool) or <false> otherwise.
	SelectTxForProposal(maxTxBytes, maxBlockGas uint64, memTx sdk.Tx, txBz []byte) bool
}

TxSelector defines a helper type that assists in selecting transactions during mempool transaction selection in PrepareProposal. It keeps track of the total number of bytes and total gas of the selected transactions. It also keeps track of the selected transactions themselves.
