Constraints for valid channel and config IDs


func UnmarshalConfig

func UnmarshalConfig(data []byte) (*cb.Config, error)

UnmarshalConfig attempts to unmarshal bytes to a *cb.Config

func UnmarshalConfigEnvelope

func UnmarshalConfigEnvelope(data []byte) (*cb.ConfigEnvelope, error)

UnmarshalConfigEnvelope attempts to unmarshal bytes to a *cb.ConfigEnvelope

func UnmarshalConfigEnvelopeOrPanic

func UnmarshalConfigEnvelopeOrPanic(data []byte) *cb.ConfigEnvelope

UnmarshalConfigEnvelopeOrPanic attempts to unmarshal bytes to a *cb.ConfigEnvelope or panics on error

func UnmarshalConfigOrPanic

func UnmarshalConfigOrPanic(data []byte) *cb.Config

UnmarshalConfigOrPanic attempts to unmarshal bytes to a *cb.Config or panics on error

func UnmarshalConfigUpdate

func UnmarshalConfigUpdate(data []byte) (*cb.ConfigUpdate, error)

UnmarshalConfigUpdate attempts to unmarshal bytes to a *cb.ConfigUpdate

func UnmarshalConfigUpdateEnvelope

func UnmarshalConfigUpdateEnvelope(data []byte) (*cb.ConfigUpdateEnvelope, error)

UnmarshalConfigUpdateEnvelope attempts to unmarshal bytes to a *cb.ConfigUpdate

func UnmarshalConfigUpdateEnvelopeOrPanic

func UnmarshalConfigUpdateEnvelopeOrPanic(data []byte) *cb.ConfigUpdateEnvelope

UnmarshalConfigUpdateEnvelopeOrPanic attempts to unmarshal bytes to a *cb.ConfigUpdateEnvelope or panics on error

func UnmarshalConfigUpdateFromPayload added in v1.4.0

func UnmarshalConfigUpdateFromPayload(payload *cb.Payload) (*cb.ConfigUpdate, error)

UnmarshalConfigUpdateFromPayload unmarshals configuration update from given payload

func UnmarshalConfigUpdateOrPanic

func UnmarshalConfigUpdateOrPanic(data []byte) *cb.ConfigUpdate

UnmarshalConfigUpdateOrPanic attempts to unmarshal bytes to a *cb.ConfigUpdate or panics on error

func ValidateChannelID

func ValidateChannelID(channelID string) error

ValidateChannelID makes sure that proposed channel IDs comply with the following restrictions:

  1. Contain only lower case ASCII alphanumerics, dots '.', and dashes '-'
  2. Are shorter than 250 characters.
  3. Start with a letter

This is the intersection of the Kafka restrictions and CouchDB restrictions with the following exception: '.' is converted to '_' in the CouchDB naming This is to accommodate existing channel names with '.', especially in the behave tests which rely on the dot notation for their sluggification.

note: this function is a copy of the same in core/tx/endorser/parser.go


type Validator added in v1.1.0

type Validator interface {
	// Validate attempts to apply a configtx to become the new config
	Validate(configEnv *cb.ConfigEnvelope) error

	// Validate attempts to validate a new configtx against the current config state
	ProposeConfigUpdate(configtx *cb.Envelope) (*cb.ConfigEnvelope, error)

	// ChannelID retrieves the channel ID associated with this manager
	ChannelID() string

	// ConfigProto returns the current config as a proto
	ConfigProto() *cb.Config

	// Sequence returns the current sequence number of the config
	Sequence() uint64

Validator provides a mechanism to propose config updates, see the config update results and validate the results of a config update.

type ValidatorImpl added in v1.1.0

type ValidatorImpl struct {
	// contains filtered or unexported fields

ValidatorImpl implements the Validator interface

func NewValidatorImpl added in v1.1.0

func NewValidatorImpl(channelID string, config *cb.Config, namespace string, pm policies.Manager) (*ValidatorImpl, error)

NewValidatorImpl constructs a new implementation of the Validator interface.

func (*ValidatorImpl) ChannelID

func (vi *ValidatorImpl) ChannelID() string

ChannelID retrieves the channel ID associated with this manager

func (*ValidatorImpl) ConfigProto added in v1.1.0

func (vi *ValidatorImpl) ConfigProto() *cb.Config

ConfigProto returns the config proto which initialized this Validator

func (*ValidatorImpl) ProposeConfigUpdate added in v1.1.0

func (vi *ValidatorImpl) ProposeConfigUpdate(configtx *cb.Envelope) (*cb.ConfigEnvelope, error)

ProposeConfigUpdate takes in an Envelope of type CONFIG_UPDATE and produces a ConfigEnvelope to be used as the Envelope Payload Data of a CONFIG message

func (*ValidatorImpl) Sequence added in v1.1.0

func (vi *ValidatorImpl) Sequence() uint64

Sequence returns the sequence number of the config

func (*ValidatorImpl) Validate added in v1.1.0

func (vi *ValidatorImpl) Validate(configEnv *cb.ConfigEnvelope) error

Validate simulates applying a ConfigEnvelope to become the new config
