  orig, Socket.do_not_reverse_lookup = Socket.do_not_reverse_lookup, true
  UDPSocket.open do |s|
    # udp is stateless, so there is no real connect

.install_json_symbol_addon ⇒ Boolean

Since this addon changes behaviour of to_json, you have to require it explicitly either with this helper method or manually with

require 'fidius-common/json_symbol_addon'

Important note: Both variants will also load and require active_support.

Returns:

  • (Boolean) —

    true if the addon was loaded successfully or false if the addon is already loaded.
