Functions

func Start 

func Start(
	platform platforms.Platform,
	cfg *config.Instance,
	st *state.State,
	inTokenQueue chan<- tokens.Token,
	confirmQueue chan<- chan error,
	db *database.Database,
	limitsManager *playtime.LimitsManager,
	profilesSvc *profiles.Service,
	notifBroker *broker.Broker,
	player audio.Player,
	playbackManager audio.PlaybackManager,
	indexPauser *syncutil.Pauser,
	scrapePauser *syncutil.Pauser,
	backupPauser *syncutil.Pauser,
	tracker RequestTracker,
) error

Start starts the API web server and blocks until it shuts down.

func StartWithReady added in v2.11.0 

func StartWithReady(
	platform platforms.Platform,
	cfg *config.Instance,
	st *state.State,
	inTokenQueue chan<- tokens.Token,
	confirmQueue chan<- chan error,
	db *database.Database,
	limitsManager *playtime.LimitsManager,
	profilesSvc *profiles.Service,
	notifBroker *broker.Broker,
	player audio.Player,
	playbackManager audio.PlaybackManager,
	indexPauser *syncutil.Pauser,
	scrapePauser *syncutil.Pauser,
	backupPauser *syncutil.Pauser,
	tracker RequestTracker,
	ready chan<- error,
	startup *StartupServer,
) error

StartWithReady starts the API web server and reports bind success or failure before blocking for shutdown. This lets service startup fail synchronously when the configured API port is unavailable.

When startup is non-nil the listener is already bound and serving the startup page, so this reuses it and swaps the full router in rather than binding a second time.

Types

type OriginsProvider added in v2.9.0 

type OriginsProvider func() []string

OriginsProvider is a function that returns custom origins from config.

type PairingManager added in v2.11.0 

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

PairingManager owns the PIN and in-flight sessions (single mutex protects all state).

func NewPairingManager added in v2.11.0 

func NewPairingManager(
	db database.UserDBI,
	notifChan chan<- models.Notification,
	opts ...PairingOption,
) *PairingManager

NewPairingManager constructs a PairingManager (pass nil notifChan to disable notifications).

func (*PairingManager) CancelPairing added in v2.11.0 

func (m *PairingManager) CancelPairing()

CancelPairing clears the current PIN and any in-flight sessions. Safe to call when no pairing is in progress.

func (*PairingManager) CountClients added in v2.16.0 

func (m *PairingManager) CountClients() (int, error)

CountClients returns the number of currently paired clients.

func (*PairingManager) HandlePairFinish added in v2.11.0 

func (m *PairingManager) HandlePairFinish() http.HandlerFunc

HandlePairFinish verifies HMAC, persists client, and returns auth token + confirmation.

func (*PairingManager) HandlePairStart added in v2.11.0 

func (m *PairingManager) HandlePairStart() http.HandlerFunc

HandlePairStart runs the PAKE exchange and returns sessionID + server message.

func (*PairingManager) PendingPIN added in v2.11.0 

func (m *PairingManager) PendingPIN() (pin string, expiresAt time.Time)

PendingPIN returns the currently displayed PIN and its expiry, or an empty PIN if no pairing is in progress.

func (*PairingManager) StartCleanup added in v2.11.0 

func (m *PairingManager) StartCleanup(ctx context.Context)

StartCleanup begins the background cleanup goroutine. The goroutine exits when ctx is canceled. Safe to call multiple times only with distinct contexts; callers should call this once during server startup.

func (*PairingManager) StartPairing added in v2.11.0 

func (m *PairingManager) StartPairing(role string) (pin string, expiresAt time.Time, err error)

StartPairing generates a new PIN (fails fast if clients are at max). role is the permission role the paired client will receive; it is chosen at this approval step because starting a pairing is a local-only action.

type PairingOption added in v2.11.0 

type PairingOption func(*PairingManager)

PairingOption configures a PairingManager at construction time.

func WithPairingCleanupInterval added in v2.11.0 

func WithPairingCleanupInterval(d time.Duration) PairingOption

WithPairingCleanupInterval overrides the cleanup goroutine tick interval.

func WithPairingMaxAttempts added in v2.11.0 

func WithPairingMaxAttempts(n int) PairingOption

WithPairingMaxAttempts overrides the maximum PIN attempts (default 3).

func WithPairingMaxClients added in v2.11.0 

func WithPairingMaxClients(n int) PairingOption

WithPairingMaxClients overrides the maximum paired clients (default 50).

func WithPairingPINTTL added in v2.11.0 

func WithPairingPINTTL(d time.Duration) PairingOption

WithPairingPINTTL overrides the PIN time-to-live (default 5min).

func WithPairingSessionTTL added in v2.11.0 

func WithPairingSessionTTL(d time.Duration) PairingOption

WithPairingSessionTTL overrides the /pair/start session TTL (default 2min).

type PairingResult added in v2.11.0 

type PairingResult struct {
	Client     *database.Client
	ServerHMAC []byte
}

PairingResult is the outcome of a successful PAKE handshake. The Client is persisted to the database; the ServerHMAC must be returned to the client so it can verify the server's identity.

type RequestTracker added in v2.12.0 

type RequestTracker interface {
	RequestStarted()
	RequestEnded()
}

RequestTracker is implemented by anything that wants to know when an API request starts and ends. The idle scheduler in pkg/service/idle satisfies it; tests can pass nil or a fake. Defined here (not in pkg/service/idle) so the api package doesn't need to import idle.

type ServiceState added in v2.18.0 

type ServiceState string

ServiceState is the coarse lifecycle state Core reports on /health. It exists because everything Core normally uses to talk to a user sits behind the databases being open, so a slow or failed database start is invisible. The listener binds before any database work and answers with one of these from that moment on. 

const (
	// ServiceStateStarting means the process is alive and working through
	// startup. Nothing but the startup page and /health answers yet.
	ServiceStateStarting ServiceState = "starting"
	// ServiceStateReady means the full API is serving.
	ServiceStateReady ServiceState = "ready"
	// ServiceStateFailed means startup stopped on something a person has to
	// resolve. Core stays bound so it can say what happened.
	ServiceStateFailed ServiceState = "failed"
)

type StartupServer added in v2.18.0 

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

StartupServer owns the API listener from before the databases open until shutdown. It serves a startup page and /health until the full router is swapped in, so a slow migration or a refused database has somewhere to be reported.

func NewStartupServer added in v2.18.0 

func NewStartupServer(ctx context.Context, cfg *config.Instance) (*StartupServer, error)

NewStartupServer binds the configured API address and immediately begins serving the startup page. It is called before any database work so that every later failure has a surface to report on.

func (*StartupServer) Done added in v2.18.0 

func (s *StartupServer) Done() <-chan error

Done reports the result of the serving goroutine.

func (*StartupServer) Listener added in v2.18.0 

func (s *StartupServer) Listener() net.Listener

Listener returns the bound listener.

func (*StartupServer) Port added in v2.18.0 

func (s *StartupServer) Port() int

Port returns the port actually bound.

func (*StartupServer) ServeHTTP added in v2.18.0 

func (s *StartupServer) ServeHTTP(w http.ResponseWriter, r *http.Request)

ServeHTTP dispatches to whichever handler is currently installed. The handler is swapped once, when the full router is ready.

func (*StartupServer) SetFailed added in v2.18.0 

func (s *StartupServer) SetFailed(headline, detail, logPath string)

SetFailed puts Core into the failed state. Core stays bound and keeps serving the page so the reason is readable without a log or a terminal.

func (*StartupServer) SetStartingDetail added in v2.18.0 

func (s *StartupServer) SetStartingDetail(detail string)

SetStartingDetail updates the sentence shown while startup is still working.

func (*StartupServer) Shutdown added in v2.18.0 

func (s *StartupServer) Shutdown(ctx context.Context) error

Shutdown stops the HTTP server and waits for it to stop serving.

The wait is what makes the port free when this returns, and callers depend on that: the failed state has to give the port back when it is stopped, and a start that ends after the listener was bound has to leave it for the next attempt. http.Server.Shutdown alone does not promise it. It closes the listeners it has been told about, and Serve registers the listener after it starts, so a shutdown landing in that window closes nothing and leaves Serve's own deferred close to do it — after Shutdown has returned. Measured at 1714 of 2000 immediate shutdowns.

func (*StartupServer) State added in v2.18.0 

func (s *StartupServer) State() ServiceState

State returns the current coarse state.

func (*StartupServer) SwapHandler added in v2.18.0 

func (s *StartupServer) SwapHandler(h http.Handler)

SwapHandler installs the full API router and marks the service ready. It is called once, after startup completes.

func (*StartupServer) WriteHealth added in v2.18.0 

func (s *StartupServer) WriteHealth(w http.ResponseWriter)

WriteHealth renders the /health body for the current state. It is used by both the startup handler and the full router so the two never disagree.
