Types

type CommonStorageDB

type CommonStorageDB struct {
	statedb.VersionedDB
	// contains filtered or unexported fields
}

CommonStorageDB implements interface DB. This implementation uses a single database to maintain both the public and private data

func (*CommonStorageDB) ApplyUpdates

func (s *CommonStorageDB) ApplyUpdates(batch *statedb.UpdateBatch, height *version.Height) error

ApplyUpdates overrides the function in statedb.VersionedDB and throws appropriate error message Otherwise, somewhere in the code, usage of this function could lead to updating only public data.

func (*CommonStorageDB) ChaincodeDeployDone added in v1.2.0

func (s *CommonStorageDB) ChaincodeDeployDone(succeeded bool)

ChaincodeDeployDone is a noop for couchdb state impl

func (*CommonStorageDB) ClearCachedVersions

func (*CommonStorageDB) GetStateMetadata added in v1.3.0

func (s *CommonStorageDB) GetStateMetadata(namespace, key string) ([]byte, error)

GetStateMetadata implements corresponding function in interface DB. This implementation provides an optimization such that it keeps track if a namespaces has never stored metadata for any of its items, the value 'nil' is returned without going to the db. This is intended to be invoked in the validation and commit path. This saves the chaincodes from paying unnecessary performance penalty if they do not use features that leverage metadata (such as key-level endorsement),

func (*CommonStorageDB) GetValueHash

func (s *CommonStorageDB) GetValueHash(namespace, collection string, keyHash []byte) (*statedb.VersionedValue, error)

func (s *CommonStorageDB) HandleChaincodeDeploy(chaincodeDefinition *cceventmgmt.ChaincodeDefinition, dbArtifactsTar []byte) error

HandleChaincodeDeploy initializes database artifacts for the database associated with the namespace This function deliberately suppresses the errors that occur during the creation of the indexes on couchdb. This is because, in the present code, we do not differentiate between the errors because of couchdb interaction and the errors because of bad index files - the later being unfixable by the admin. Note that the error suppression is acceptable since peer can continue in the committing role without the indexes. However, executing chaincode queries may be affected, until a new chaincode with fixed indexes is installed and instantiated

func (*UpdatesBytesBuilder) DeterministicBytesForPubAndHashUpdates added in v1.4.2

func (bb *UpdatesBytesBuilder) DeterministicBytesForPubAndHashUpdates(u *UpdateBatch) ([]byte, error)

DeterministicBytesForPubAndHashUpdates constructs the bytes for a given UpdateBatch while constructing the bytes, it considers only public writes and hashed writes for the collections. For achieving the determinism, it constructs a slice of proto messages of type 'KVWriteProto'. In the slice, all the writes for a namespace "ns1" appear before the writes for another namespace "ns2" if "ns1" < "ns2" (lexicographically). Within a namespace, all the public writes appear before the collection writes. Like namespaces, the collections writes within a namespace appear in the order of lexicographical order. If an entry has the same namespace as its preceding entry, the namespace field is skipped. A Similar treatment is given to the repetitive entries for a collection within a namespace. For illustration, see the corresponding unit tests
