Description

I was reviewing the test failures and noticed some Jenkins machines fail on the below test, as I understand it it's possible for the locale function in appcd-response to return null, so I believe it would make sense for appcd-client to have a default for the Accepts-Language header, which would probably be en or *. Alternatively just fix the regex check to accept null.

 1) Client request() should make a request to the mock server:
     AssertionError: expected 'null' to match /^([a-z]{2})(?:[-_](?:\w+[-_])?([A-Z]{2}))?$/i

Comments

Chris Barber 2017-12-04 locale() returning null is valid. appcd-client should probably only set the Accept-Language if the locale is not null. Internally, the WebSocketSession will pass the Accept-Language value to the appcd-response Message.toString() which in turn tolerates null locales. So this ticket comes down to not setting the locale if it's null and fixing the unit test in the event locale is null.
