  • Predefined role permission lists are representative, not Google's complete lists.
  • System-managed signing keys are not rotated.
  • SetIamPolicy ignores update_mask; TestIamPermissions grants everything requested.
  • Condition lint is syntactic only (no CEL parsing, no policy-level lint).
  • Deleted-service-account and deleted-role retention windows (30 and 7/37 days) are the documented figures, not verified against the live service.

Functions

This section is empty.

Types

type ConfigProvider 

type ConfigProvider interface {
	GetGCPIAMSettings() Settings
}

ConfigProvider extracts Cloud IAM configuration from the AppContext Config.

type Handler 

type Handler struct {
	Backend *InMemoryBackend

	Port int
	// contains filtered or unexported fields
}

Handler serves the Cloud IAM admin gRPC API on a dedicated listener.

func NewHandler 

func NewHandler(backend *InMemoryBackend) *Handler

NewHandler creates a Handler; callers override Port from Settings.

func (*Handler) API 

func (h *Handler) API() adminpb.IAMServer

API exposes the IAM admin service for in-process callers (dashboard proxy).

func (*Handler) Addr 

func (h *Handler) Addr() string

Addr returns the bound listener address, or "" before StartWorker.

func (*Handler) ExtractOperation 

func (h *Handler) ExtractOperation(*echo.Context) string

ExtractOperation is unused: requests never reach the shared router.

func (*Handler) ExtractResource 

func (h *Handler) ExtractResource(*echo.Context) string

ExtractResource is unused: requests never reach the shared router.

func (*Handler) GetSupportedOperations 

func (h *Handler) GetSupportedOperations() []string

GetSupportedOperations lists the supported gRPC methods.

func (*Handler) Handler 

func (h *Handler) Handler() echo.HandlerFunc

Handler returns a 404 handler; the real API is gRPC on the dedicated port.

func (*Handler) MatchPriority 

func (h *Handler) MatchPriority() int

MatchPriority is irrelevant because RouteMatcher never matches.

func (*Handler) Name 

func (h *Handler) Name() string

Name returns the service name.

func (*Handler) Reset 

func (h *Handler) Reset()

Reset clears all in-memory state.

func (*Handler) Restore 

func (h *Handler) Restore(ctx context.Context, data []byte) error

Restore implements persistence.Persistable by delegating to the backend.

func (*Handler) RouteMatcher 

func (h *Handler) RouteMatcher() service.Matcher

RouteMatcher never matches: Cloud IAM runs on its own gRPC listener.

func (*Handler) Shutdown 

func (h *Handler) Shutdown(ctx context.Context)

Shutdown stops the gRPC server.

func (*Handler) Snapshot 

func (h *Handler) Snapshot(ctx context.Context) []byte

Snapshot implements persistence.Persistable by delegating to the backend.

func (*Handler) StartWorker 

func (h *Handler) StartWorker(ctx context.Context) error

StartWorker binds the dedicated listener synchronously so a port conflict is returned to the caller.
