A regular expression error occurs when running Quantum service on a Red Hat installation. The Quantum service is not able to process any requests on account of which this error. The exception trace can be found at http://paste.openstack.org/show/1638/
The offending regular expression appears to be coming from the URL mapper for the "port" resource:
^/tenants\/(?P<tenant_id>[^/]+?)\/networks\/(?P<network_id>[^/]+?)\/port
s\/(?P<id>[^/]+?)\/attachment(?P<.format>[^/]+?)(/)?$
Trying to validate the above regex points to a "group" error.
Possible workaround is to comment out the mapper.connect() calls for the "port" resource in quantum/api/__init__.py
I did not see this error when running Quantum on Ubuntu. Is this an artifact of an incorrect "routes" version that I might be running on RHEL, or is it something else? Any pointers are appreciated.
Thanks,
~Sumit.
