Functions

func ImplicitMetaPolicyWithSubPolicy 

func ImplicitMetaPolicyWithSubPolicy(subPolicyName string, rule cb.ImplicitMetaPolicy_Rule) *cb.ConfigPolicy

ImplicitMetaPolicyWithSubPolicy creates an implicitmeta policy

func TemplateImplicitMetaAllPolicy 

func TemplateImplicitMetaAllPolicy(path []string, policyName string) *cb.ConfigGroup

TempateImplicitMetaAnyPolicy returns TemplateImplicitMetaPolicy with cb.ImplicitMetaPolicy_ALL as the rule

func TemplateImplicitMetaAnyPolicy 

func TemplateImplicitMetaAnyPolicy(path []string, policyName string) *cb.ConfigGroup

TempateImplicitMetaAnyPolicy returns TemplateImplicitMetaPolicy with cb.ImplicitMetaPolicy_ANY as the rule

func TemplateImplicitMetaMajorityPolicy 

func TemplateImplicitMetaMajorityPolicy(path []string, policyName string) *cb.ConfigGroup

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 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)

	// Basepath returns the basePath the manager was instantiated with
	BasePath() string

	// Policies returns all policy names defined in the manager
	PolicyNames() []string
}

Manager is a read only subset of the policy ManagerImpl

type ManagerImpl 

type ManagerImpl struct {

	// SuppressSanityLogMessages when set to true will prevent the sanity checking log
	// messages.  Useful for novel cases like channel templates
	SuppressSanityLogMessages bool
	// 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(basePath string, providers map[int32]Provider) *ManagerImpl

NewManagerImpl creates a new ManagerImpl with the given CryptoHelper

func (*ManagerImpl) BasePath 

func (pm *ManagerImpl) BasePath() string

Basepath returns the basePath the manager was instnatiated with

func (*ManagerImpl) BeginPolicyProposals 

func (pm *ManagerImpl) BeginPolicyProposals(tx interface{}, groups []string) ([]Proposer, error)

BeginPolicies is used to start a new config proposal

func (*ManagerImpl) CommitProposals 

func (pm *ManagerImpl) CommitProposals(tx interface{})

CommitProposals is used to commit a new config proposal

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

func (*ManagerImpl) PolicyNames 

func (pm *ManagerImpl) PolicyNames() []string

func (*ManagerImpl) PreCommit 

func (pm *ManagerImpl) PreCommit(tx interface{}) error

PreCommit is currently a no-op for the policy manager and always returns nil

func (*ManagerImpl) ProposePolicy 

func (pm *ManagerImpl) ProposePolicy(tx interface{}, key string, configPolicy *cb.ConfigPolicy) (proto.Message, error)

ProposePolicy takes key, path, and ConfigPolicy and registers it in the proposed PolicyManager, or errors It also returns the deserialized policy value for tracking and inspection at the invocation side.

func (*ManagerImpl) RollbackProposals 

func (pm *ManagerImpl) RollbackProposals(tx interface{})

RollbackProposals is used to abandon a new config proposal

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 Proposer 

type Proposer interface {
	// BeginPolicyProposals starts a policy update transaction
	BeginPolicyProposals(tx interface{}, groups []string) ([]Proposer, error)

	// ProposePolicy createss a pending policy update from a ConfigPolicy and returns the deserialized
	// value of the Policy representation
	ProposePolicy(tx interface{}, name string, policy *cb.ConfigPolicy) (proto.Message, error)

	// RollbackProposals discards the pending policy updates
	RollbackProposals(tx interface{})

	// CommitProposals commits the pending policy updates
	CommitProposals(tx interface{})

	// PreCommit tests if a commit will apply
	PreCommit(tx interface{}) error
}

Proposer is the interface used by the configtx manager for policy management

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
