[New-bugs-announce] [issue28562] test_asyncio fails on Android upon calling getaddrinfo()

[Xavier de Gaye]

New submission from Xavier de Gaye:

The error:
======================================================================
ERROR: test_create_connection_service_name (test.test_asyncio.test_base_events.BaseEventLoopWithSelectorTests)
----------------------------------------------------------------------
Traceback (most recent call last):

The same error occurs also in issue 26936.
msg266362 lists the conditions under which getaddrinfo() fails on Android.

With this patch, the test succeeds on both Android API levels 21 and 23 (there is no level 22).
