var Migrations = migrate.NewGroup("warden")

Migrations is the grove migration group for the Warden store. It can be registered with the grove extension for orchestrated migration management (locking, version tracking, rollback support).

Types

type Option added in v1.7.0 

type Option func(*storeConfig)

Option configures a Store at construction time.

func WithStatementTimeout added in v1.7.0 

func WithStatementTimeout(d time.Duration) Option

WithStatementTimeout returns an Option that caps how long a single statement may run on Postgres before the server cancels it (statement_timeout), so a runaway query can't hold a connection forever.

Grove's pgdriver (v1.6.3) builds its pgxpool.Config from the DSN and doesn't expose pgxpool's AfterConnect hook through a driver.Option, so there is no way to guarantee every connection the pool ever opens picks this up. Store applies it as a session-level SET on the connection it acquires immediately at construction (best-effort, useful for a single-connection pool, or as a default before traffic arrives). For a setting that reliably reaches every connection the pool opens, prefer the DSN's `options` startup parameter instead, which pgx applies at connect time for every physical connection: 

postgres://user:pass@host/db?options=-c%20statement_timeout%3D5000

type Store 

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

Store is a PostgreSQL implementation of the composite Warden store.

func New 

func New(db *grove.DB, opts ...Option) *Store

New creates a new PostgreSQL store. See WithStatementTimeout for the caveats of setting statement_timeout after the pool already exists.

func (*Store) UpdatePolicyIfVersion added in v1.7.0 

func (s *Store) UpdatePolicyIfVersion(ctx context.Context, p *policy.Policy, expected int) error

UpdatePolicyIfVersion writes p as UpdatePolicy does, only if the stored policy is at version expected. The version check is part of the UPDATE's WHERE clause, so the comparison and the write are one statement: under READ COMMITTED a second writer blocks on the row lock, then re-checks the WHERE against the committed row and matches nothing. When no row changes, a read picks the error: not found if the policy is absent from p's tenant, a version conflict otherwise. That read only chooses the error; the refusal itself was atomic.

p.UpdatedAt is set only once the write has happened, so a refused caller's struct does not claim a write that did not happen.

func (*Store) UpdateResourceType 

func (s *Store) UpdateResourceType(ctx context.Context, rt *resourcetype.ResourceType) error

func (*Store) UpdateRole 

func (s *Store) UpdateRole(ctx context.Context, r *role.Role) error
