Comment 0 for bug 1313556

When using the API client to delete a resource, the resource is deleted all right but the client blocks forever.

= How to reproduce =

Assuming you've got a MAAS server installed on localhost:

# Create admin user.
sudo maas-region-admin createadmin --username admin --password test --email <email address hidden>
# Set up maas cli.
sudo maas login maas http://localhost/MAAS/api/1.0/ `sudo maas-region-admin apikey --username admin`
# Create a zone object.
sudo maas maas zones create name=test_zone
# Get the api key for the admin user.
sudo maas-region-admin apikey --username admin
<grab the API key>

# Now, in a python shell:
python

>>> from apiclient.creds import convert_string_to_tuple
>>> from apiclient.maas_client import (
... MAASClient,
... MAASDispatcher,
... MAASOAuth,
... urllib2,
... )
>>> credentials = convert_string_to_tuple('<Replace with the API key>')
>>> auth = MAASOAuth(*credentials)
>>> client = MAASClient(auth, MAASDispatcher(), "http://localhost/MAAS")
>>> zone_uri = u'/api/1.0/zones/test_zone/'
>>> client.delete(zone_uri)
<blocked forever>

= Notes =

Note that, if you CTL-C the last command (the deletion of the zone), `sudo maas maas zones read` will show that the zone has effectively be deleted.

= Workaround =

A (pretty ugly) workaround is to set a timeout to `urlopen` used by the API client.

>>> from functools import partial
>>> urlopen_with_timeout = partial(urllib2.urlopen, timeout=4)
>>> from apiclient import maas_client
>>> maas_client.urllib2.urlopen = urlopen_with_timeout
