Hi, I found out that nova currently handles list with limit=0 quite different for different objects. Especially when list servers: According to the code: http://git.openstack.org/cgit/openstack/nova/tree/nova/api/openstack/common.py#n206 when limit = 0, it should apply as max_limit, but currently, in: http://git.openstack.org/cgit/openstack/nova/tree/nova/db/sqlalchemy/api.py#n1930 we directly return [], this is quite different with comment in the api code. I checked other objects: when list security groups and server groups, it will return as no limit has been set. And for flavors it returns []. I will continue to try out other APIs if needed. I think maybe we should make a rule for all objects, at least fix the servers to make it same in api and db code. I have reported a bug in launchpad: https://bugs.launchpad.net/nova/+bug/1494617 Any suggestions? Best Regards, Zheng -------------- next part -------------- An HTML attachment was scrubbed...
