OverflowError at /project/network_topology/

[Nguyen Hai]

I installed DevStack with master branch of all the projects and the local.conf at /tacker/devstack/local.conf.example.

When I go to topology view in the dashboard, it can not show the topology.

Trackback leads to:
...
File "/opt/stack/horizon/openstack_dashboard/usage/quotas.py" in add_quota
  145. self.usages[quota.name]['quota'] = int(quota.limit)

Exception Type: OverflowError at /project/network_topology/
Exception Value: cannot convert float infinity to integer

The full traceback is here: http://dpaste.com/0M8JP1H

    Handle float('inf') in tenant_quota_usages properly

    tenant_absolute_limits API wrapper converts -1 (unlimited)
    to float('inf'), but tenant_quota_usages() cannot handle this
    properly. This is a regression during the quota refactoring work.
    This commit changes QuotaUsage.add_quota() to accept float('inf')
    as one of unlimited quota value.
