802879 - Bagheera uses HTTP 406 improperly

Status: RESOLVED FIXED

(Mozilla Metrics :: Metrics Data Ping, defect)

Description

[Gregory Szorc [:gps]]

Bagheera is currently using HTTP 406 (Not Acceptable) improperly. From httpbis (the eventual RFC 2616 successor):

   https://tools.ietf.org/html/draft-ietf-httpbis-p2-semantics-21#section-7.5.6

   The resource identified by the request is only capable of generating
   response representations which have content characteristics not
   acceptable according to the Accept and Accept-* header fields sent in
   the request.

In short, 406 involves Accept* headers. Bagheera is using "Not Acceptable" in the English meaning of the words, not what the spec defines.

HTTP 400 or 200 + an error in the response document are acceptable alternatives.

See http://docs.services.mozilla.com/storage/apis-2.0.html for an HTTP API that does things properly.

This is fixed and deployed. It will now return a 400 Bad Request instead of a 406.
