Discussion:
If go-restful detects a particular method is not allowed, it will return this error: That is preventing useful methods that resthandler would generate from making it to the client. Expected response:
triggered with
/cc
/cc
Is the right fix to update the client to generate the message versus changing the server to allow the method and report the error? My bias is to improve the client and not change the server as it makes reading our swagger doc easier to not see a bunch of verb unsupported entries. Sent from my iPhone
My bias is also towards not changing the server to keep swagger spec correct. By changing the client, do you mean changing kubectl? can you please clarify how is the json useful to client? It does not contain any useful extra information. On Feb 11, 2015 7:28 PM, "Derek Carr" wrote:

This was an unintended side effect, but I think the old behavior was an unexpected luxury? I agree from the end-user perspective, the old message was nice, and it's great that the client was politely told that a given verb was not supported on the resource, but I don't agree that a server should appear to accept a method to only report that its not allowed. ----- Original Message ----- From: "Jordan Liggitt" To: "GoogleCloudPlatform/kubernetes" Cc: "Derek Carr" Sent: Thursday, February 12, 2015 1:04:41 PM Subject: Re: [kubernetes] go-restful is emitting less helpful errors than resthandler () Returning an API response would allow clients that expect API status to get nice messages for free, instead of spitting this out: We can certainly put the burden of interpreting 405 errors on all clients, just seemed nice not to.

If we want to leave go-restful returning that as an intended and considered side-effect, that's fine. Is the consensus that this issue should change to update kubectl to show a nicer message for that error?
I think so, this is only going to get worse when we support specific types of verbs on specific resources. In practice, it seems fine for kubectl to give a better error specific to the method not allowed response. ----- Original Message ----- From: "Jordan Liggitt" To: "GoogleCloudPlatform/kubernetes" Cc: "Derek Carr" Sent: Thursday, February 12, 2015 1:26:08 PM Subject: Re: [kubernetes] go-restful is emitting less helpful errors than resthandler () If we want to leave go-restful returning that as an intended and considered side-effect, that's fine.

We could consider submitting a PR to go-restful to allow us to provide an error-generation function or interface implementation.
Yeah, that seems reasonable.

Copying text from : Some errors return as json and some as plain text. This causes overhead on client side when parsing the errors since need to recheck content type for every error in order not to parse plain text as json (some libraries fail on that). The errors message format should be standardized. Examples: The text/plain errors are from go-restful. cc
+1, thanks
The status objects are always of the default API version, however, rather than the version requested, because the request object isn't available to the error handler.
Rather than: we need:
Can we define an error handler on a web service?
At the moment, it's at the container level:
David and I talked about keeping the API lookup mechanism so we could use that in the error handler (apirequestinfo). We still need it for some use cases (proxies) so it could be used here to identify the version and proposed resource if matched.
