Public bug reported:
There's a race condition in instance_create, that allows creation
several instances with duplicate hostname/display_name. Before storing
instance record in database, there's a query for existing records with
same hostname.
with session.begin():
if 'hostname' in values:
_validate_unique_server_name(context, session, values['hostname'])
instance_ref.security_groups = _get_sec_group_models(session,
security_groups)
session.add(instance_ref)
If another instance with same hostname is stored after
_validate_unique_server_name, there will be duplicates.
We hit this bug when badly-written client resubmitted POST request after
timeout.
