	Resources  *Resources
	MyOrgMSPID string
	// contains filtered or unexported fields
}

func NewCache

HandleStateUpdates is required to implement the ledger state listener interface. It applies any state updates to the cache.

func (*Cache) Initialize 

func (c *Cache) Initialize(channelID string, qe ledger.SimpleQueryExecutor) error

Initialize will populate the set of currently committed chaincode definitions for a channel into the cache. Note, it this looks like a bit of a DRY violation with respect to 'Update', but, the error handling is quite different and attempting to factor out the common pieces results in a net total of more code.

func (*Cache) InitializeLocalChaincodes 

func (c *Cache) InitializeLocalChaincodes() error

InitializeLocalChaincodes should be called once after cache creation (timing doesn't matter, though already installed chaincodes will not be invokable until it it completes). Ideally, this would be part of the constructor, but, we cannot rely on the chaincode store being created before the cache is created.

type ExternalFunctions 

type ExternalFunctions struct {
	Resources       *Resources
	InstallListener InstallListener
}

ExternalFunctions is intended primarily to support the SCC functions. In general, its methods signatures produce writes (which must be commmitted as part of an endorsement flow), or return human readable errors (for instance indicating a chaincode is not found) rather than sentinals. Instead, use the utility functions attached to the lifecycle Resources when needed.

RequiresInit returns whether this chaincode must have Init commit before invoking.

func (*LegacyDefinition) Validation 

func (ld *LegacyDefinition) Validation() (string, []byte)

type Serializer 

type Serializer struct {
	// Marshaler, when nil uses the standard protobuf impl.
	// Can be overridden for test.
	Marshaler Marshaler
}

Serializer is used to write structures into the db and to read them back out. Although it's unfortunate to write a custom serializer, rather than to use something pre-written, like protobuf or JSON, in order to produce precise readwrite sets which only perform state updates for keys which are actually updated (and not simply set to the same value again) custom serialization is required.

func (*Serializer) Deserialize 

func (s *Serializer) Deserialize(namespace, name string, metadata *lb.StateMetadata, structure interface{}, state ReadableState) error

Deserialize accepts a struct (of a type previously serialized) and populates it with the values from the db. Note: The struct names for the serialization and deserialization must match exactly. Unencoded fields are not populated, and the extraneous keys are ignored. The metadata provided should have been returned by a DeserializeMetadata call for the same namespace and name.

func (s *Serializer) IsMetadataSerialized(namespace, name string, structure interface{}, state OpaqueState) (bool, error)

func (*Serializer) IsSerialized 

func (s *Serializer) IsSerialized(namespace, name string, structure interface{}, state OpaqueState) (bool, error)

IsSerialized essentially checks if the hashes of a serialized version of a structure matches the hashes of the pre-image of some struct serialized into the database.

func (*Serializer) SerializableChecks 

func (s *Serializer) SerializableChecks(structure interface{}) (reflect.Value, []string, error)

SerializableChecks performs some boilerplate checks to make sure the given structure is serializable. It returns the reflected version of the value and a slice of all field names, or an error.

func (*Serializer) Serialize 

func (s *Serializer) Serialize(namespace, name string, structure interface{}, state ReadWritableState) error

Serialize takes a pointer to a struct, and writes each of its fields as keys into a namespace. It also writes the struct metadata (if it needs updating) and, deletes any keys in the namespace which are not found in the struct. Note: If a key already exists for the field, and the value is unchanged, then the key is _not_ written to.

type SimpleQueryExecutorShim 

type SimpleQueryExecutorShim struct {
	Namespace           string
	SimpleQueryExecutor ledger.SimpleQueryExecutor
}

SimpleQueryExecutorShim implements the ReadableState and RangeableState interfaces based on an underlying ledger.SimpleQueryExecutor

func (*SimpleQueryExecutorShim) GetState 

func (sqes *SimpleQueryExecutorShim) GetState(key string) ([]byte, error)

func (*SimpleQueryExecutorShim) GetStateRange 

func (sqes *SimpleQueryExecutorShim) GetStateRange(prefix string) (map[string][]byte, error)

type StateIterator 

type StateIterator interface {
	Close() error
	Next() (*queryresult.KV, error)
}

type ValidatorCommitter 

type ValidatorCommitter struct {
	Resources                    *Resources
	LegacyDeployedCCInfoProvider LegacyDeployedCCInfoProvider
}

func (*ValidatorCommitter) ChaincodeImplicitCollections 

func (vc *ValidatorCommitter) ChaincodeImplicitCollections(channelName string) ([]*cb.StaticCollectionConfig, error)

ChaincodeImplicitCollections assumes the chaincode exists in the new lifecycle and returns the implicit collections

func (*ValidatorCommitter) ChaincodeInfo 

func (vc *ValidatorCommitter) ChaincodeInfo(channelName, chaincodeName string, qe ledger.SimpleQueryExecutor) (*ledger.DeployedChaincodeInfo, error)

func (*ValidatorCommitter) CollectionInfo 

func (vc *ValidatorCommitter) CollectionInfo(channelName, chaincodeName, collectionName string, qe ledger.SimpleQueryExecutor) (*cb.StaticCollectionConfig, error)

CollectionInfo implements function in interface ledger.DeployedChaincodeInfoProvider, it returns config for both static and implicit collections.

func (*ValidatorCommitter) CollectionValidationInfo 

func (vc *ValidatorCommitter) CollectionValidationInfo(channelID, chaincodeName, collectionName string, state validationState.State) (args []byte, unexpectedErr, validationErr error)

CollectionValidationInfo returns information about collections to the validation component

func (*ValidatorCommitter) ImplicitCollectionEndorsementPolicyAsBytes 

func (vc *ValidatorCommitter) ImplicitCollectionEndorsementPolicyAsBytes(channelID, orgMSPID string) (policy []byte, unexpectedErr, validationErr error)

func (*ValidatorCommitter) ImplicitCollections 

func (vc *ValidatorCommitter) ImplicitCollections(channelName, chaincodeName string, qe ledger.SimpleQueryExecutor) ([]*cb.StaticCollectionConfig, error)

ImplicitCollections implements function in interface ledger.DeployedChaincodeInfoProvider. It returns a slice that contains one proto msg for each of the implicit collections

func (*ValidatorCommitter) LifecycleEndorsementPolicyAsBytes 

func (vc *ValidatorCommitter) LifecycleEndorsementPolicyAsBytes(channelID string) ([]byte, error)

func (*ValidatorCommitter) Namespaces 

func (vc *ValidatorCommitter) Namespaces() []string

Namespaces returns the list of namespaces which are relevant to chaincode lifecycle

func (*ValidatorCommitter) UpdatedChaincodes 

func (vc *ValidatorCommitter) UpdatedChaincodes(stateUpdates map[string][]*kvrwset.KVWrite) ([]*ledger.ChaincodeLifecycleInfo, error)

UpdatedChaincodes returns the chaincodes that are getting updated by the supplied 'stateUpdates'

func (*ValidatorCommitter) ValidationInfo 

func (vc *ValidatorCommitter) ValidationInfo(channelID, chaincodeName string, qe ledger.SimpleQueryExecutor) (plugin string, args []byte, unexpectedErr error, validationErr error)

ValidationInfo returns the name and arguments of the validation plugin for the supplied chaincode. The function returns two types of errors, unexpected errors and validation errors. The reason for this is that this function is called from the validation code, which needs to differentiate the two types of error to halt processing on the channel if the unexpected error is not nil and mark the transaction as invalid if the validation error is not nil.

type ValidatorStateShim 

type ValidatorStateShim struct {
	ValidatorState validatorstate.State
	Namespace      string
}

func (*ValidatorStateShim) GetState 

func (vss *ValidatorStateShim) GetState(key string) ([]byte, error)
