  We have additional coverage of getaddrinfo through the resolv tests, so
the loss of default test coverage seems acceptable.

2017-11-13  Florian Weimer  <fweimer@redhat.com>

	[BZ #20826]
	Turn posix/tst-getaddrinfo5 into xtest due to Internet requirement.
	* posix/Makefile (tests): Remove tst-getaddrinfo5.
	(xtests): Add tst-getaddrinfo5.

IMHO, this test should succeed even without network access, provided
that /etc/hosts contains an entry for localhost, which is something
pretty standard. However nss_files only consider exact matching, and
doesn't consider 'localhost.' being the same as 'localhost'.

We will eventually run this test in a newtork namespace with a known
configured hosts file. Until that point I think it needs to remain an
xtest. We should not rely on the host being configured in any magical
way.

DJ is currently looking at running tests in a minimal namespace to
allow us to do exactly this kind of testing. If you have any interest
in that please reach out to DJ.

tst-getaddrinfo4 has the same problem.

Should we turn both into xtests?

Thanks,

Either both or neither.
