[Bug 1334297] [NEW] Strange response from os-server-groups with bad parameter

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

There was a bug in tempest that caused a call to DELETE os-server-groups
with a bad id. Here is the call from the tempest log:

2014-06-25 12:07:03.162 25653 INFO tempest.common.rest_client [-]
Request (ServerGroupTestJSON:tearDownClass): 200 DELETE
http://127.0.0.1:8774/v2/2bc18b72010d455a9db7cbc583e1dcfc/os-server-
groups/{u'policies': [u'affinity'], u'name': u'server-group-1944635656',
u'id': u'7c6a13c1-6d8b-4314-9d16-4eb6418a2170', u'members': [],
u'metadata': {}} 0.001s

Normally DELETE will return 204 and in this case I would have expected
400. But the call returns 200. What can be seen in the nova log seems to
indicate 400 but that is not what is actually getting sent back:
