dist/IO/t/cachepropagate-unix ................................. #   Failed test 'datagram socket created'

Can't call method "protocol" on an undefined value at t/cachepropagate-unix.t line 77.
# Looks like you planned 15 tests but ran 9.
# Looks like you failed 1 test of 9 run.
# Looks like your test exited with 48 just after 9.
FAILED at test 9


prove-5.20 -l cachepropagate-unix.t 

works with Perl 5.20.3 and the tests fails with 5.22.1 as well.

As an added bonus, here are the problems with 5.24: #51330

Quoting Tony from the upstream ticket:

This test passes successfully on both 10.10.5 and 10.11.4 with a default build of blead perl (5.24 + unrelated changes).

pallas:t tony$ ./perl harness -v ../dist/IO/t/cachepropagate-unix.t 
../dist/IO/t/cachepropagate-unix.t .. 
ok 1 - stream socket created
ok 2 - protocol defined
ok 3 - domain defined
ok 4 - type defined
ok 5 - spawned a child
ok 6 - domain match
ok 7 # skip no Socket::SO_PROTOCOL
ok 8 - type match
ok 9 - datagram socket created
ok 10 - protocol defined
ok 11 - domain defined
ok 12 - type defined
ok 13 - domain match
ok 14 # skip no Socket::SO_PROTOCOL
ok 15 - type match
All tests successful.
Files=1, Tests=15,  1 wallclock secs ( 0.01 usr  0.00 sys +  0.08 cusr  0.01 csys =  0.10 CPU)
Result: PASS

(not using MacPorts)

5.22.2 also passes.

I don't have 10.7 to test against.

Since I can't reproduce it here, you might try adding some diagnostic code, the code that's failing is:

    # now test datagram sockets:
    $listener = IO::Socket::UNIX->new(Type => SOCK_DGRAM,
                                      Local => $socketpath);
    ok(defined($listener), 'datagram socket created');

you might try changing that to:

    # now test datagram sockets:
    $listener = IO::Socket::UNIX->new(Type => SOCK_DGRAM,
                                      Local => $socketpath)
      or diag "datagram socket: $!";
    ok(defined($listener), 'datagram socket created');

and see if you get a useful diagnostic.

To test just the single test file:

  ./Configure ... your flags here ...
  make test TEST_ARGS=-v TEST_FILES=../dist/IO/t/cachepropagate-unix.t

On OS X 10.10, I can reproduce failures with both perl 5.20 and perl 5.24. Although I get "Address already in use" with the suggested diag added to the test code:

ok 8 - type match
# datagram socket: Address already in use
not ok 9 - datagram socket created
#   Failed test 'datagram socket created'

As far as I tested, this issue seems to be our custom $TMPDIR value in the environment, on my system that would be: TMPDIR=/opt/local/var/macports/build/_Users_raimue_src_macports_trunk_dports_lang_perl5/perl5.24/work/.tmp.

My wild guess is that the path is truncated somewhere due to its length, and the socket/bind syscall only sees a substring of the given path that triggers the "Address already in use" because this substring is an existing path. I can make the test also fail reproducibly with the following sequence. Although also the stream socket test #1 may fail sometimes (depending on path length?).

$ sudo port -v build perl5.24
$ cd $(port work perl5.24)/perl-5.24.0
$ sudo -u macports env TMPDIR=/tmp/$(perl -le 'print "A" x 150;') sh -c 'rm -rf $TMPDIR && mkdir $TMPDIR && make test TEST_ARGS=-v TEST_FILES=../dist/IO/t/cachepropagate-unix.t'
