Variables

var MaxCommitOrTagMessageSize = 10 * 1024

MaxCommitOrTagMessageSize is the threshold for a commit/tag message, if exceeded then message is truncated and it's up to the client to request it in full separately.

var Unimplemented = status.Errorf(codes.Unimplemented, "this rpc is not implemented")

Unimplemented is a Go error with gRPC error code 'Unimplemented'

Functions

func ByteSliceHasAnyPrefix

func ByteSliceHasAnyPrefix(s []byte, prefixes ...string) bool

ByteSliceHasAnyPrefix tests whether the byte slice s begins with any of the prefixes.

func ContainsPathTraversal

func ContainsPathTraversal(path string) bool

ContainsPathTraversal checks if the path contains any traversal

func DecorateError

func DecorateError(code codes.Code, err error) error

DecorateError unless it's already a grpc error.

If given nil it will return nil.

func ExtractGitalyServers

func ExtractGitalyServers(ctx context.Context) (gitalyServersInfo storage.GitalyServers, err error)

ExtractGitalyServers extracts `storage.GitalyServers` from an incoming context.

func GetPath

func GetPath(repo *gitalypb.Repository) (string, error)

GetPath returns the path of the repo passed as first argument. An error is returned when either the storage can't be found or the path includes constructs trying to perform directory traversal.

func GetRepoPath

func GetRepoPath(repo *gitalypb.Repository) (string, error)

GetRepoPath returns the full path of the repository referenced by an RPC Repository message. The errors returned are gRPC errors with relevant error codes and should be passed back to gRPC without further decoration.

func GetStorageByName

func GetStorageByName(storageName string) (string, error)

GetStorageByName will return the path for the storage, which is fetched by its key. An error is return if it cannot be found.

func GrpcCode

func GrpcCode(err error) codes.Code

GrpcCode emulates the old grpc.Code function: it translates errors into codes.Code values.

func IsGitDirectory

func IsGitDirectory(dir string) bool

IsGitDirectory checks if the directory passed as first argument looks like a valid git directory.

func IsNumber

func IsNumber(s []byte) bool

IsNumber tests whether the byte slice s contains only digits or not

func UnquoteBytes

func UnquoteBytes(s []byte) []byte

UnquoteBytes removes surrounding double-quotes from a byte slice returning a new slice if they exist, otherwise it returns the same byte slice passed.
