TempateImplicitMetaAnyPolicy returns TemplateImplicitMetaPolicy with cb.ImplicitMetaPolicy_MAJORITY as the rule

func TemplateImplicitMetaPolicy

func TemplateImplicitMetaPolicy(path []string, policyName string, rule cb.ImplicitMetaPolicy_Rule) *cb.ConfigGroup

TemplateImplicitMetaPolicy creates a policy at the specified path with the given policyName It utilizes the policyName for the subPolicyName as well, as this is the standard usage pattern

func TemplateImplicitMetaPolicyWithSubPolicy

func TemplateImplicitMetaPolicyWithSubPolicy(path []string, policyName string, subPolicyName string, rule cb.ImplicitMetaPolicy_Rule) *cb.ConfigGroup

TemplateImplicitMetaPolicy creates a policy at the specified path with the given policyName and subPolicyName

Types

type ChannelPolicyManagerGetter

type ChannelPolicyManagerGetter interface {
	// Returns the policy manager associated to the passed channel
	// and true if it was the manager requested, or false if it is the default manager
	Manager(channelID string) (Manager, bool)
}

ChannelPolicyManagerGetter is a support interface to get access to the policy manager of a given channel

type ConfigPolicy

type ConfigPolicy interface {
	// Key is the key this value should be stored in the *cb.ConfigGroup.Policies map.
	Key() string

	// Value is the backing policy implementation for this ConfigPolicy
	Value() *cb.Policy
}

ConfigPolicy defines a common representation for different *cb.ConfigPolicy values.

type InquireablePolicy

type InquireablePolicy interface {
	// SatisfiedBy returns a slice of PrincipalSets that each of them
	// satisfies the policy.
	SatisfiedBy() []PrincipalSet
}

InquireablePolicy is a Policy that one can inquire

type Manager

type Manager interface {
	// GetPolicy returns a policy and true if it was the policy requested, or false if it is the default policy
	GetPolicy(id string) (Policy, bool)

	// Manager returns the sub-policy manager for a given path and whether it exists
	Manager(path []string) (Manager, bool)
}

Manager is a read only subset of the policy ManagerImpl

type ManagerImpl

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

ManagerImpl is an implementation of Manager and configtx.ConfigHandler In general, it should only be referenced as an Impl for the configtx.ConfigManager

func NewManagerImpl

func NewManagerImpl(path string, providers map[int32]Provider, root *cb.ConfigGroup) (*ManagerImpl, error)

NewManagerImpl creates a new ManagerImpl with the given CryptoHelper

func (*ManagerImpl) GetPolicy

func (pm *ManagerImpl) GetPolicy(id string) (Policy, bool)

GetPolicy returns a policy and true if it was the policy requested, or false if it is the default reject policy

func (*ManagerImpl) Manager

func (pm *ManagerImpl) Manager(path []string) (Manager, bool)

Manager returns the sub-policy manager for a given path and whether it exists

type Policy

type Policy interface {
	// Evaluate takes a set of SignedData and evaluates whether this set of signatures satisfies the policy
	Evaluate(signatureSet []*cb.SignedData) error
}

Policy is used to determine if a signature is valid

type PrincipalSet

type PrincipalSet []*msp.MSPPrincipal

PrincipalSet is a collection of MSPPrincipals

func (PrincipalSet) ContainingOnly

func (ps PrincipalSet) ContainingOnly(f func(*msp.MSPPrincipal) bool) bool

ContainingOnly returns whether the given PrincipalSet contains only Principals that satisfy the given predicate

func (PrincipalSet) UniqueSet

func (ps PrincipalSet) UniqueSet() map[*msp.MSPPrincipal]int

UniqueSet returns a histogram that is induced by the PrincipalSet

type PrincipalSets

type PrincipalSets []PrincipalSet

PrincipalSets aggregates PrincipalSets

func (PrincipalSets) ContainingOnly

func (psSets PrincipalSets) ContainingOnly(f func(*msp.MSPPrincipal) bool) PrincipalSets

ContainingOnly returns PrincipalSets that contain only principals of the given predicate

type Provider

type Provider interface {
	// NewPolicy creates a new policy based on the policy bytes
	NewPolicy(data []byte) (Policy, proto.Message, error)
}

Provider provides the backing implementation of a policy

type StandardConfigPolicy

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

StandardConfigValue implements the ConfigValue interface.
