            Bug ID: 377563
           Summary: perlqt-4.14.3: qtgui/t/networkfortune.t test hangs
                    because of IPv6
           Product: bindings
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: kde-bindings at kde.org
          Reporter: ppisar at redhat.com
  Target Milestone: ---

When running perlqt-4.14.3 tests, qtgui/t/networkfortune.t hangs here:

$ perl -I/home/test/fedora/perl-Qt/perlqt-4.14.3/build/blib/{arch,lib}
/home/test/fedora/perl-Qt/perlqt-4.14.3/qtgui/t/networkfortune.t 
Config: Using QTest library 4.8.7, Qt 4.8.7
ok 1 - Window shown
PASS   : NetworkFortuneTest::initTestCase()

and a dialog window about "connection refused by peer" error appears.

The reason is that the testing server listens on IPv4 0.0.0.0 address, but the
client having "Localhost" host name
(qtgui/examples/network/fortuneclient/Client.pm:69) connects to IPv6 ::1,
receives ECONNREFUSED and does not retry next associated Localhost address,
IPv4 127.0.0.1, that would succeed.

This is probably bug in Qt::TcpSocket::connectToHost() (called from sub
requestNewFortune() in fortuneclient/Client.pm). It gives up on first
connection error instead of trying all addresses resolved from given host name.

Simple workaround in the the Perl binding tests is to connect to 127.0.0.1
instead of Localhost. But I think the real bug is Qt library and it should be
fixed there.
