This happens on the buildds too (3 times on release archs), see below.
Also, this package has had it's share of FTBFS bugs due to failing
tests, so I wonder if this should be fixed with wack-a-mole or if it's
better to disable the test suite. I tried to make sense of the different
failures to fix bug 998097, but there have been so many tries to fix or
disable several tests that I couldn't make sense of it in the time I
spent on it. I have the feeling that some of the timeout issues are due
to the test suite not properly cleaning up if one test fails and than
hanging later on.
For documentation purposes, at least I got this from archeology (all but
test_kb.rb pass on my system):
disabled_tests= [
+ # has a tast that (sometimes?) seems to hang
'tests/test_exc.rb',
+ # some tests requiring network access
'tests/test_get_sock_opt.rb',
+ # several tests need internet (google.com)
'tests/test_httpclient2.rb',
+ # several tests need internet (google.com)
'tests/test_httpclient.rb',
+ # some tests requiring network access
'tests/test_idle_connection.rb',
+ # mips sometimes too slow
'tests/test_inactivity_timeout.rb',
+ # error: terminate called after throwing an instance of
'std::runtime_error' what(): unable to add new descriptor: Operation not
permitted
'tests/test_kb.rb',
+ # one test needs internet (192.0.2.0)
'tests/test_pending_connect_timeout.rb',
+ # several tests need internet
'tests/test_resolver.rb',
+ # some tests requiring network access
'tests/test_set_sock_opt.rb',
+ # one test needs internet (192.0.2.0)
'tests/test_unbind_reason.rb',
