New submission from Ronald Oussoren <[email protected]>:
I just noticed that test_urllib fails for me because urllib.request.thishost()
fails:
======================================================================
ERROR: test_thishost (test.test_urllib.Utility_Tests)
Test the urllib.request.thishost utility function returns a tuple
----------------------------------------------------------------------
Traceback (most recent call last):
File "/Users/ronald/Projects/python/rw/default/Lib/test/test_urllib.py", line
1155, in test_thishost
self.assertIsInstance(urllib.request.thishost(), tuple)
File "/Users/ronald/Projects/python/rw/default/Lib/urllib/request.py", line
2236, in thishost
_thishost = tuple(socket.gethostbyname_ex(socket.gethostname())[2])
socket.gaierror: [Errno 8] nodename nor servname provided, or not known
----------------------------------------------------------------------
This is because this host's hostname (Gondolin.local) is not in DNS because my
mDNSReponder detected a conflict and picked a different name to advertise in
the .local zone without updating the hostname.
The reason I report this anyway is that URLopener.open_local_file seems to
assume that thishost() cannot fail, and the error condition on my machine could
easily happen on other systems as well.
BTW. The use of this host() in URLopener.open_local_file is wrong for other
reasons as well: it assumes that the local machine has exactly 1 IP address,
and won't correctly detect that a file is local when the IP address is one of
the other IP addresses on a multi homed system.
