In hindsight, maybe the message could have been better,

Fix test_asyncio for AIX - do not call transport.get_extra_info('sockname')
(#8907)
FYI:
I have a server where "netstat -in" (aka ip a) does show an address with a
scope component. Not figured out how to query that in C or python yet. (not my
favorite thing - messing with socket() :p@me)
Re: the example below - I would have thought the scopeid would be showing on
en1, not en2 - and I am also wondering, if the scopeid is "%1" AIX ignores it.
(also, I masked my global ipv6 address).
Maybe en0 has a scopeid BECAUSE there is a global address (where en1 does not).

So, I looked at another server with two interfaces - here only one has a IPv6
address
root@x064:[/home/root]netstat -in
Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll
en0 1500 link#2 0.21.5e.a3.c7.44 119801 0 84874 0 0

en0 1500 fe80::221:5eff:fea3:c744 119801 0 84874 0 0
en1 1500 link#3 fa.d1.81.81.ac.5 89362 0 48409 0 0
en1 1500 192.168.2 192.168.2.64 89362 0 48409 0 0
lo0 16896 link#1 139882 0 139881 0 0
lo0 16896 127 127.0.0.1 139882 0 139881 0 0
lo0 16896 ::1%1 139882 0 139881 0 0
root@x064:[/home/root]
And, after I activate IPv6 on the second interface - I see a scopeid-like
representation:
Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll
en0 1500 link#2 0.21.5e.a3.c7.44 120043 0 85045 0 0

en1 1500 link#3 fa.d1.81.81.ac.5 89370 0 48420 0 0
en1 1500 192.168.2 192.168.2.64 89370 0 48420 0 0
en1 1500 fe80::f8d1:81ff:fe81:ac05%2 89370 0 48420 0 0
lo0 16896 link#1 139923 0 139922 0 0
lo0 16896 127 127.0.0.1 139923 0 139922 0 0
lo0 16896 ::1%1 139923 0 139922 0 0
I would have to guess at this point, but to simplify, it seems that AIX
resolves addresses differently (rather than say 'not correctly') and maybe
requires specific conditions.
If relevant - I can provide the output from Debian on POWER. But it seems AIX
is only using a "ADDRv6%scopeid" when there at least two interfaces defined.

FYI: I have IPv6 interfaces defined on this server (x066) - but only one. And I
tried changing fe80::1%1 to fe80::1%2, etc, but the end result is similar:
AssertionError: expected call not found.
Expected: connect(('fe80::1', 80, 0, 2))
Actual: connect(('fe80::1', 80, 0, 0))
Hope this helps!
