----------------------------------------------------------
Commit 24112cf6ce9ed23029f7697b84548dc8acff28b5 in couchdb-couch-log's branch
refs/heads/master from [~jaydoane]
[ https://git-wip-us.apache.org/repos/asf?p=couchdb-couch-log.git;h=24112cf ]
Fix dns timeout for undefined syslog host
On some platforms, inet:getaddr can take several seconds to return when
passed the undefined atom, which is the default value of "syslog_host",
and therefore the value used when running tests. On platforms where it
takes longer to return than the test is allowed to run, the
couch_log_writer_syslog_test will fail with *timed out*.
This short circuits the case when "syslog_host" is undefined, and
removes the race from the test.
