const AllowedCharsCollectionName = "[A-Za-z0-9_-]+"

func ValidateMetadataFile Uses

func ValidateMetadataFile(filePathName string, fileBytes []byte) error

ValidateMetadataFile checks that metadata files are valid according to the validation rules of the file's directory

type MetadataProvider Uses

type MetadataProvider interface {
    GetMetadataAsTarEntries() ([]byte, error)
}

MetadataProvider is implemented by each platform in a platform specific manner. It can process metadata stored in ChaincodeDeploymentSpec in different formats. The common format is targz. Currently users expect the metadata to be presented as tar file entries (directly extracted from chaincode stored in targz format). In future, we would like provide better abstraction by extending the interface

type TargzMetadataProvider Uses

    Code []byte
}

TargzMetadataProvider provides Metadata from chaincode packaged in Targz format (go, java and node platforms)

func (*TargzMetadataProvider) GetMetadataAsTarEntries Uses

func (tgzProv *TargzMetadataProvider) GetMetadataAsTarEntries() ([]byte, error)

GetMetadataAsTarEntries extracts metata data from ChaincodeDeploymentSpec

type UnhandledDirectoryError Uses

type UnhandledDirectoryError struct {
