Making Temfile.make_tmpname give a better quality unique name

gistfile1.rb

  require 'tempfile'

  class Tempfile

    # overriding so that the Time component of the tmpname including hours, seconds and usecs, was previously just year + month + day
    def make_tmpname(basename, n)
      case basename
      when Array
        prefix, suffix = *basename
      else
        prefix, suffix = basename, ''
      end
 
      t = Time.now.to_i.to_s + Time.now.usec.to_s
      path = "#{prefix}#{t}-#{$$}-#{rand(0x100000000).to_s(36)}-#{n}#{suffix}"
    end

  end
