Using version 1.1 of the compute API

I have an active server with id of: 3 When updating the name of a Server using a PUT request (/v1.1/servers/3) the server name gets updated just fine, but the response is a "204 No Content"

The OpenStack Compute Dev Guide V1.1 (4.1.4. Update Server) lists the following response codes:

Normal Response Code(s): 200 Error Response Code(s): computeFault (400, 500, …), serviceUnavailable (503), unauthorized (401), forbidden (403), badRequest (400), badMethod (405), overLimit (413), itemNotFound (404), badMediaType (415), buildInProgress (409)

Is this a bug or just out-of-date documentation?

The documentation is wrong here. A PUT operation should not respond with a 200, but instead a 202 or a 204. In this case, the 204 behavior is correct and the documentation should be changed to reflect that.

The documentation is correct. The spec defines the the response as having content, therefore a 204 (no content) is not acceptable. A 202 implies an asynchronous operation, which is not the case here. The spec is correct as defining a 200, Nova is just not implementing it correctly. Please file a bug for this.
