Overview

The (new) redis manager is intended to look like the officially supported memory manager. We take the tradeoff for slower inserts and deletions to make it easier to find applicable policies.

Types

type RedisManager

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

RedisManager is a redis implementation of Manager to store policies persistently.

func NewRedisManager

func NewRedisManager(db *redis.Client, keyPrefix string) *RedisManager

NewRedisManager initializes a new RedisManager with no policies

func (*RedisManager) Create

func (m *RedisManager) Create(policy Policy) error

Create a new policy in Redis. It will create a single key for the policy itself, and for each subject and resource the policy will also exist in a hashmap.

func (*RedisManager) Delete

func (m *RedisManager) Delete(id string) error

Delete removes a policy.

func (*RedisManager) FindPoliciesForResource

func (m *RedisManager) FindPoliciesForResource(resource string) (Policies, error)

FindPoliciesForResource returns policies that could match the resource. It either returns a set of policies that apply to the resource, or a superset of it. If an error occurs, it returns nil and the error.

func (*RedisManager) FindPoliciesForSubject

func (m *RedisManager) FindPoliciesForSubject(subject string) (Policies, error)

FindPoliciesForSubject returns policies that could match the subject. It either returns a set of policies that applies to the subject, or a superset of it. If an error occurs, it returns nil and the error.

func (*RedisManager) FindRequestCandidates

func (m *RedisManager) FindRequestCandidates(r *Request) (Policies, error)

FindRequestCandidates returns candidates that could match the request object. It either returns a set that exactly matches the request, or a superset of it. If an error occurs, it returns nil and the error.

func (*RedisManager) Get

func (m *RedisManager) Get(id string) (Policy, error)

Get retrieves a policy.

func (*RedisManager) GetAll

func (m *RedisManager) GetAll(limit int64, offset int64) (Policies, error)

GetAll retrieves all policies. (Equivelant of db.keys + db.Mget)

func (*RedisManager) Update

func (m *RedisManager) Update(policy Policy) error
