Title:
Deleting router-gateway-port throws a DB foreign key error
Status in neutron:
New
Bug description:
1. High level description:
Create a external network and associate to a router during creation using
"--external_gateway_info type=dict network_id=" option.
This creates a gateway-port. When you attempt to delete this gateway port you
get a DB foreign key error as follows:
"DBError: (IntegrityError) (1451, 'Cannot delete or update a pare
nt row: a foreign key constraint fails (`neutron`.`routers`, CONSTRAINT
`routers_ibfk_1` FOREIGN KEY (`gw_port_id`) REFERENC
ES `ports` (`id`))') 'DELETE FROM ports WHERE ports.id = %s'
('76573418-f9ff-4f2d-8ffb-d0a200f7f1ea',)"
2. Pre-conditions:
All resources are created as a admin tenant
3. Step-by-step reproduction steps:
Steps and error message posted here:
http://paste.openstack.org/show/489584/
4. Expected output:
If this action is not supported then an error message similar to
following should be thrown:
"More than one external network exists"
5. Actual output:
we get "Request Failed: internal server error while processing your
request."
With a DB trace on neutron logs
6. Version:
Master Branch (Mitaka) (also applicable in liberty/kilo)
Devstack installation for Mitaka
