Artifact 43991614fd16dc5e2fec947fb48ac19954c7dac60bd10f4ab79ba8138e967832:

• File tests/SocketTests.m — part of check-in [8f810ecb7e] at 2018-08-11 14:00:46 on branch trunk — Change the layout of of_socket_address_t

  Instead of containing a struct sockaddr_storage - which does not exist
  on all supported platforms - it now contains a union of all struct
  sockaddr_* types.

  Additionally, if struct sockaddr_in6 does not exist, it is defined so
  that an IPv6 can be stored even if the system does not support IPv6. (user: js, size: 8549) [annotate] [blame] [check-ins using]
