Functions

func ExtractFileDescriptor

func ExtractFileDescriptor(gz []byte) (*descriptor.FileDescriptorProto, error)

ExtractFileDescriptor extracts a FileDescriptorProto from a gzip'd buffer. https://github.com/golang/protobuf/blob/9eb2c01ac278a5d89ce4b2be68fe4500955d8179/descriptor/descriptor.go#L50

Types

type MethodInfo

type MethodInfo struct {
	Operation OpType
	Scope     Scope
	// contains filtered or unexported fields
}

MethodInfo contains metadata about the RPC method. Refer to documentation for message type "OperationMsg" shared.proto in ./proto for more documentation.

func (MethodInfo) TargetRepo

func (mi MethodInfo) TargetRepo(msg proto.Message) (*gitalypb.Repository, error)

TargetRepo returns the target repository for a protobuf message if it exists

func (MethodInfo) UnmarshalRequestProto

func (mi MethodInfo) UnmarshalRequestProto(b []byte) (proto.Message, error)

UnmarshalRequestProto will unmarshal the bytes into the method's request message type

type OpType

type OpType int

OpType represents the operation type for a RPC method

type Registry

type Registry struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

Registry contains info about RPC methods

var (
	// GitalyProtoFileDescriptors is a slice of all gitaly registered file
	// descriptors
	GitalyProtoFileDescriptors []*descriptor.FileDescriptorProto
	// GitalyProtoPreregistered is a proto registry pre-registered with all
	// GitalyProtoFileDescriptors file descriptor protos
	GitalyProtoPreregistered *Registry
)

GitalyProtoFileDescriptors is a slice of all gitaly registered file descriptors

func New

func New() *Registry

New creates a new ProtoRegistry

func (*Registry) LookupMethod

func (pr *Registry) LookupMethod(fullMethodName string) (MethodInfo, error)

LookupMethod looks up an MethodInfo by service and method name

func (*Registry) RegisterFiles

func (pr *Registry) RegisterFiles(protos ...*descriptor.FileDescriptorProto) error

RegisterFiles takes one or more descriptor.FileDescriptorProto and populates the registry with its info

type Scope

type Scope int

Scope represents the intended scope of an RPC method
