Golang FmtOutput Examples

Example #1

File: server.go Project: 0xfed/write-ups

func (s *Server) execute(query []byte) ([]byte, error) {
	output, err := s.sql.Execute(s.cluster.State(), string(query))

	if err != nil {
		var msg string
		if output != nil && len(output.Stderr) > 0 {
			template := `Error executing %#v (%s)

SQLite error: %s`
			msg = fmt.Sprintf(template, query, err.Error(), util.FmtOutput(output.Stderr))
		} else {
			msg = err.Error()
		}

		return nil, errors.New(msg)
	}

	formatted := fmt.Sprintf("SequenceNumber: %d\n%s",
		output.SequenceNumber, output.Stdout)
	return []byte(formatted), nil
}

Example #2

File: sql_command.go Project: jstanley0/stripe-ctf-3

// Writes a value to a key.
func (c *SqlCommand) Apply(server raft.Server) (interface{}, error) {
	db := server.Context().(*sql.SQL)
	output, err := db.Execute("tehrafts", inflate(c.Query))

	if err != nil {
		var msg string
		if output != nil && len(output.Stderr) > 0 {
			template := `Error executing %#v (%s)

SQLite error: %s`
			msg = fmt.Sprintf(template, c.Query, err.Error(), util.FmtOutput(output.Stderr))
		} else {
			msg = err.Error()
		}

		return nil, errors.New(msg)
	}

	formatted := fmt.Sprintf("SequenceNumber: %d\n%s",
		output.SequenceNumber, output.Stdout)
	return []byte(formatted), nil
}
