GitHub user Kami opened a pull request:
https://github.com/apache/libcloud/pull/711
Throw a more user-friendly exception on "No address associated with
hostname" error
Usually this issue represents a bug in the driver (`host` connection class
attribute being set to an incorrect value), but the original exception is kinda
cryptic so it's hard for the users to figure out what is going on.
Before:
```python
Traceback (most recent call last):
File "example.py", line 5, in <module>
print driver.list_zones()
File "/home/kami/w/lc/libcloud/libcloud/dns/drivers/godaddy.py", line
146, in list_zones
'/v1/domains/').object
File "/home/kami/w/lc/libcloud/libcloud/common/base.py", line 827, in
request
headers=headers)
File "/usr/lib64/python2.7/httplib.py", line 1053, in request
self._send_request(method, url, body, headers)
File "/usr/lib64/python2.7/httplib.py", line 1093, in _send_request
self.endheaders(body)
File "/usr/lib64/python2.7/httplib.py", line 1049, in endheaders
self._send_output(message_body)
File "/usr/lib64/python2.7/httplib.py", line 893, in _send_output
self.send(msg)
File "/usr/lib64/python2.7/httplib.py", line 855, in send
self.connect()
File "/home/kami/w/lc/libcloud/libcloud/httplib_ssl.py", line 284, in
connect
self.timeout)
File "/usr/lib64/python2.7/socket.py", line 557, in create_connection
for res in getaddrinfo(host, port, 0, SOCK_STREAM):
socket.gaierror: [Errno -5] No address associated with hostname
```
After:
```python
Traceback (most recent call last):
File "example.py", line 5, in <module>
print driver.list_zones()
File "/home/kami/w/lc/libcloud/libcloud/dns/drivers/godaddy.py", line
146, in list_zones
'/v1/domains/').object
File "/home/kami/w/lc/libcloud/libcloud/common/base.py", line 842, in
request
raise socket.gaierror(msg)
socket.gaierror: [Errno -5] No address associated with hostname. Perhaphs
"host" Connection class attribute (GoDaddyDNSConnection.connection) is set to
an invalid, non-hostname value (http://www.google.com)?

Throw a more user-friendly error on "No address associated with hostname"
exception.
This could simply indicate Connection.host attribute being set to an invalid
value.
