Functions

func InitStateStorage 

func InitStateStorage(ctx context.Context, cfg *ApplicationConfig) (storage.LocalBackend, storage.NodeDB, *storage.Root, error)

InitStateStorage initializes the internal ABCI state storage.

Types

type ApplicationConfig 

type ApplicationConfig struct {
	DataDir         string
	StorageBackend  string
	Pruning         PruneConfig
	HaltEpochHeight epochtime.EpochTime
	MinGasPrice     uint64
	DisableCheckTx  bool

	DisableCheckpointer       bool
	CheckpointerCheckInterval time.Duration

	// OwnTxSigner is the transaction signer identity of the local node.
	OwnTxSigner signature.PublicKey

	// MemoryOnlyStorage forces in-memory storage to be used for the state storage.
	MemoryOnlyStorage bool

	// ReadOnlyStorage forces read-only access for the state storage.
	ReadOnlyStorage bool

	// InitialHeight is the height of the initial block.
	InitialHeight uint64
}

ApplicationConfig is the configuration for the consensus application.

type ApplicationServer 

type ApplicationServer struct {
	// contains filtered or unexported fields
}

ApplicationServer implements a tendermint ABCI application + socket server, that multiplexes multiple Oasis-specific "applications".

func NewApplicationServer 

func NewApplicationServer(ctx context.Context, upgrader upgrade.Backend, cfg *ApplicationConfig) (*ApplicationServer, error)

NewApplicationServer returns a new ApplicationServer, using the provided directory to persist state.

func (*ApplicationServer) Cleanup 

func (a *ApplicationServer) Cleanup()

Cleanup cleans up the state of an ApplicationServer instance.

func (*ApplicationServer) EstimateGas 

func (a *ApplicationServer) EstimateGas(caller signature.PublicKey, tx *transaction.Transaction) (transaction.Gas, error)

EstimateGas calculates the amount of gas required to execute the given transaction.

func (*ApplicationServer) Mux 

func (a *ApplicationServer) Mux() types.Application

Mux retrieve the abci Mux (or tendermint application) served by this server.

func (*ApplicationServer) Quit 

func (a *ApplicationServer) Quit() <-chan struct{}

Quit returns a channel which is closed when the ApplicationServer is stopped.

func (*ApplicationServer) Register 

func (a *ApplicationServer) Register(app api.Application) error

Register registers an Oasis application with the ABCI multiplexer.

All registration must be done before Start is called. ABCI operations that act on every single app (InitChain, BeginBlock, EndBlock) will be called in name lexicographic order. Checks that applications named in deps are already registered.

func (*ApplicationServer) RegisterHaltHook 

func (a *ApplicationServer) RegisterHaltHook(hook func(ctx context.Context, blockHeight int64, epoch epochtime.EpochTime))

RegisterHaltHook registers a function to be called when the consensus Halt epoch height is reached.

func (*ApplicationServer) SetEpochtime 

func (a *ApplicationServer) SetEpochtime(epochTime epochtime.Backend) error

SetEpochtime sets the mux epochtime.

Epochtime must be set before the multiplexer can be used.

func (*ApplicationServer) SetTransactionAuthHandler 

func (a *ApplicationServer) SetTransactionAuthHandler(handler api.TransactionAuthHandler) error

SetTransactionAuthHandler configures the transaction auth handler for the ABCI multiplexer.

func (*ApplicationServer) Start 

func (a *ApplicationServer) Start() error

Start starts the ApplicationServer.

func (*ApplicationServer) State 

func (a *ApplicationServer) State() api.ApplicationQueryState

State returns the application state.

func (*ApplicationServer) Stop 

func (a *ApplicationServer) Stop()

Stop stops the ApplicationServer.

func (*ApplicationServer) TransactionAuthHandler 

func (a *ApplicationServer) TransactionAuthHandler() api.TransactionAuthHandler

TransactionAuthHandler returns the configured handler for authenticating transactions.

func (*ApplicationServer) WatchInvalidatedTx 

func (a *ApplicationServer) WatchInvalidatedTx(txHash hash.Hash) (<-chan error, pubsub.ClosableSubscription, error)

WatchInvalidatedTx adds a watcher for when/if the transaction with given hash becomes invalid due to a failed re-check.

type MockABCIMux 

type MockABCIMux struct {
	// contains filtered or unexported fields
}

MockABCIMux exports some of the muxer's internal methods for testing use.

func NewMockMux 

func NewMockMux(ctx context.Context, upgrader upgrade.Backend, cfg *ApplicationConfig) (*MockABCIMux, error)

NewMockMux creates a new ABCI mux suitable for testing.

func (MockABCIMux) ApplySnapshotChunk 

func (mux MockABCIMux) ApplySnapshotChunk(req types.RequestApplySnapshotChunk) types.ResponseApplySnapshotChunk

func (MockABCIMux) BeginBlock 

func (mux MockABCIMux) BeginBlock(req types.RequestBeginBlock) types.ResponseBeginBlock

func (MockABCIMux) CheckTx 

func (mux MockABCIMux) CheckTx(req types.RequestCheckTx) types.ResponseCheckTx

func (MockABCIMux) Commit 

func (mux MockABCIMux) Commit() types.ResponseCommit

func (MockABCIMux) DeliverTx 

func (mux MockABCIMux) DeliverTx(req types.RequestDeliverTx) types.ResponseDeliverTx

func (MockABCIMux) EndBlock 

func (mux MockABCIMux) EndBlock(req types.RequestEndBlock) types.ResponseEndBlock

func (MockABCIMux) EstimateGas 

func (mux MockABCIMux) EstimateGas(caller signature.PublicKey, tx *transaction.Transaction) (transaction.Gas, error)

func (MockABCIMux) Info 

func (mux MockABCIMux) Info(req types.RequestInfo) types.ResponseInfo

func (MockABCIMux) InitChain 

func (mux MockABCIMux) InitChain(req types.RequestInitChain) types.ResponseInitChain

func (MockABCIMux) ListSnapshots 

func (mux MockABCIMux) ListSnapshots(req types.RequestListSnapshots) types.ResponseListSnapshots

func (MockABCIMux) LoadSnapshotChunk 

func (mux MockABCIMux) LoadSnapshotChunk(req types.RequestLoadSnapshotChunk) types.ResponseLoadSnapshotChunk

func (*MockABCIMux) MockClose 

func (mux *MockABCIMux) MockClose()

MockClose cleans up the muxer's state; it must be called once the muxer is no longer needed.

func (*MockABCIMux) MockRegisterApp 

func (mux *MockABCIMux) MockRegisterApp(app api.Application) error

MockRegisterApp is used to register apps with this muxer during testing.

func (*MockABCIMux) MockSetEpochtime 

func (mux *MockABCIMux) MockSetEpochtime(epochTime epochtime.Backend)

MockSetEpochtime sets the timesource used by this muxer when testing.

func (*MockABCIMux) MockSetTransactionAuthHandler

type PruneConfig 

type PruneConfig struct {
	// Strategy is the PruneStrategy used.
	Strategy PruneStrategy

	// NumKept is the number of versions retained when applicable.
	NumKept uint64
}

PruneConfig is the pruning strategy and related configuration.

type PruneStrategy 

type PruneStrategy int

PruneStrategy is the strategy to use when pruning the ABCI mux state. 

const (
	// PruneNone retains all versions.
	PruneNone PruneStrategy = iota

	// PruneKeepN retains the last N latest versions.
	PruneKeepN
)

func (*PruneStrategy) FromString 

func (s *PruneStrategy) FromString(str string) error

func (PruneStrategy) String 

func (s PruneStrategy) String() string

type StatePruner 

type StatePruner interface {
	// Prune purges unneeded versions from the ABCI mux node database,
	// given the latest version, based on the underlying strategy.
	//
	// This method is NOT safe for concurrent use.
	Prune(ctx context.Context, latestVersion uint64) error

	// GetLastRetainedVersion returns the earliest version below which all
	// versions can be discarded from block history. Zero indicates that
	// no versions can be discarded.
	//
	// This method can be called concurrently with Prune.
	GetLastRetainedVersion() uint64
}

StatePruner is a concrete ABCI mux state pruner implementation.
