Overview ¶

Package internal provides support for package appengine.

Programs should not use this package directly. Its API is not stable. Use packages appengine and appengine/* instead.

var NamespaceMods = make(map[string]func(m proto.Message, namespace string))

NamespaceMods is a map from API service to a function that will mutate an RPC request to attach a namespace. The function should be prepared to be called on the same message more than once; it should only modify the RPC request the first time.

Functions ¶

func AppID ¶

func AppID(c netcontext.Context) string

func BackgroundContext ¶

func BackgroundContext() netcontext.Context

func Call ¶

func Call(ctx netcontext.Context, service, method string, in, out proto.Message) error

func ContextForTesting ¶

func ContextForTesting(req *http.Request) netcontext.Context

func Datacenter ¶

func Datacenter(ctx netcontext.Context) string

func DefaultTicket ¶ added in v1.1.0

func DefaultTicket() string

DefaultTicket returns a ticket used for background context or dev_appserver.

func DefaultVersionHostname ¶

func DefaultVersionHostname(ctx netcontext.Context) string

func FullyQualifiedAppID ¶

func FullyQualifiedAppID(ctx netcontext.Context) string

FullyQualifiedAppID returns the fully-qualified application ID. This may contain a partition prefix (e.g. "s~" for High Replication apps), or a domain prefix (e.g. "example.com:").

func IncomingHeaders ¶

func IncomingHeaders(ctx netcontext.Context) http.Header

func InstanceID ¶

func InstanceID() string

func IsDevAppServer ¶

func IsDevAppServer() bool

func Logf ¶

func Logf(ctx netcontext.Context, level int64, format string, args ...interface{})

func Main ¶

func Main()

func ModuleName ¶

func ModuleName(_ netcontext.Context) string

func NamespaceFromContext ¶

func NamespaceFromContext(ctx netcontext.Context) string

func NamespacedContext ¶

func NamespacedContext(ctx netcontext.Context, namespace string) netcontext.Context

NamespacedContext wraps a Context to support namespaces.

func RegisterErrorCodeMap ¶

func RegisterErrorCodeMap(service string, m map[int32]string)

RegisterErrorCodeMap is called from API implementations to register their error code map. This should only be called from init functions.

func RegisterTestRequest ¶

func RegisterTestRequest(req *http.Request, apiURL *url.URL, decorate func(netcontext.Context) netcontext.Context) (*http.Request, func())

RegisterTestRequest registers the HTTP request req for testing, such that any API calls are sent to the provided URL. It returns a closure to delete the registration. It should only be used by aetest package.

func RegisterTimeoutErrorCode ¶

func RegisterTimeoutErrorCode(service string, code int32)

func RegisterTransactionSetter ¶

func RegisterTransactionSetter(f interface{})

RegisterTransactionSetter registers a function that sets transaction information in a protocol buffer message. f should be a function with two arguments, the first being a protocol buffer type, and the second being *datastore.Transaction.

func ReqContext ¶ added in v1.1.0

func ReqContext(req *http.Request) netcontext.Context

func RequestID ¶

func RequestID(ctx netcontext.Context) string

func RunTransactionOnce ¶

func RunTransactionOnce(c netcontext.Context, f func(netcontext.Context) error, xg bool, readOnly bool, previousTransaction *pb.Transaction) (*pb.Transaction, error)

func ServerSoftware ¶

func ServerSoftware() string

func SetTestEnv ¶ added in v1.1.0

func SetTestEnv() func()

SetTestEnv sets the env variables for testing background ticket in Flex.

func VersionID ¶

func VersionID(_ netcontext.Context) string

func WithAppIDOverride ¶

func WithAppIDOverride(ctx netcontext.Context, appID string) netcontext.Context

func WithCallOverride ¶

func WithCallOverride(ctx netcontext.Context, f CallOverrideFunc) netcontext.Context

func WithContext ¶

func WithContext(parent netcontext.Context, req *http.Request) netcontext.Context

func WithLogOverride ¶

func WithLogOverride(ctx netcontext.Context, f logOverrideFunc) netcontext.Context

Types ¶

type APIError ¶

type APIError struct {
	Service string
	Detail  string
	Code    int32 // API-specific error code
}

APIError is the type returned by appengine.Context's Call method when an API call fails in an API-specific way. This may be, for instance, a taskqueue API call failing with TaskQueueServiceError::UNKNOWN_QUEUE.

func (*APIError) Error ¶

func (e *APIError) Error() string

func (*APIError) IsTimeout ¶

func (e *APIError) IsTimeout() bool

type CallError ¶

type CallError struct {
	Detail string
	Code   int32
	// TODO: Remove this if we get a distinguishable error code.
	Timeout bool
}

CallError is the type returned by appengine.Context's Call method when an API call fails in a generic way, such as RpcError::CAPABILITY_DISABLED.

func (*CallError) Error ¶

func (e *CallError) Error() string

func (*CallError) IsTimeout ¶

func (e *CallError) IsTimeout() bool

type CallOverrideFunc ¶

type CallOverrideFunc func(ctx netcontext.Context, service, method string, in, out proto.Message) error
