    bpo-34521: Fix tests in test_multiprocessing_spawn to use correctly CMSG_SPACE (GH-9613) (GH-9619) · 007fda43
    Miss Islington (bot) yazdı
    After some failures in AMD64 FreeBSD CURRENT Debug 3.x buildbots
    regarding tests in test_multiprocessing_spawn and after examining
    similar failures in test_socket, some errors in the calculation of
    ancillary data buffers were found in multiprocessing.reduction.
    
    CMSG_LEN() can often be used as the buffer size for recvmsg() to
    receive a single item of ancillary data, but RFC 3542 requires portable
    applications to use CMSG_SPACE() and thus include space for padding,
    even when the item will be the last in the buffer.
    
    The failures we experience are due to the usage of CMSG_LEN() instead of
    CMSG_SPACE().
