Subject: [PATCH] Do not default IO::Socket::IP to AI_ADDRCONFIG flag
|
|

t/40connect.t fails if the only available network interface is
|
|
loopback and IO::Socket::IP is installed:
|
|
|
|
# perl -Ilib -I. t/40connect.t
|
|
1..3
|
|
ok 1 - client with IPv4/IPv6 auto-selection, bound to ::1
|
|
ldap://localhost:9009/ Name or service not known at t/common.pl line 157.
|
|
# Looks like your test exited with 22 just after 1.
|
|
|
|
The reason is that IO::Socket::IP by default resolves host names with
|
|
AI_ADDRCONFIG flag and in the particular case (no interfaces other
|
|
than loopback) a system resolver (glibc in my case) hides both IPv4
|
|
and IPv6 addreses of the hostname (e.g. localhost).
|
|
|
|
See <https://rt.cpan.org/Ticket/Display.html?id=104793> for more
|
|
details.
|
|
|
|
I applied a workaround similar to one found in IO-Socket-SSL.
|
|
I believe that other Socket implementations perl-ldap can use do not
|
|
suffer from this problem.
