[Bug 1718877] [NEW] nova-api returns 500 error(DBError) if nova list API is called with filters with empty string
Public bug reported:
If nova list API is called with filter as empty regex pattern like below:
http://<host-ip>/compute/v2.1/servers?name=""
it fails at db layer with below error and returns 500 InternalServerError
to user:
InternalError: (1139, u"Got error 'empty (sub)expression' from
regexp")
Looks like the issue is there for every query parameter which is using below
regex parameter types defined in parameter_types.py:
common_query_regex_param
Reproduction steps:
