OpenStack API returning blank endpoints #564

Open termie opened 13 years ago

termie commented 13 years ago

When you auth with the OS API, you get endpoints back in the headers, such as X-Server-Management-Url. If an endpoint doesn't exist you still get it, such as a blank X-Storage-Url and X-Cdn-Management-Url

(by ttx) What does the published API say about that ?

that it should be returning empty strings ? (so you ask for change in API)
that it should not return headers ? (so this is a bug)
nothing at all ? (so you ask for a change in default behavior)

(by mike-mayo) Good question. I looked over the spec and couldn't find anything about this topic.

So I'm proposing we change the default behavior to only return an endpoint header if it actually exists. Or at the very least, document that you may get a blank one back. That said, I think not returning the header at all is smarter since I imagine some people will want to run OpenStack for only a subset of services, which could one day mean some people are looking at a lot of blank headers.

(by ttx) A bit concerned about changing this behavior after FeatureFreeze, but I guess letting a release pass without deciding might not be better.
