This change includes:
- Improve the spec coverage for incoming request to the webfinger action
- For requests without an accept header (ie, what a browser might look like),
return a JSON response.
- For requests with an explicit format of xml or json, return that format.
- For requests using an accept header, return that format.
Also adds failing spec showing webfinger does not return xml, which covers the
issue described in: https://github.com/tootsuite/mastodon/issues/1983
* Add locale spec with failing locale plus region check
* Use a more accurate locale when supplied by browser headers
Previously we were using a matching option which would use the first locale
available which matched the locale portion, even if a region was specified.
This changes to first try to find an exact match, and then fall back to the
region, and then fall back to the default.
* Clean up default_locale method
* Add request spec for host meta route returning xml
* Add routing spec for xrd routes
* Update well-known routes
* Move webfinger and host-meta actions to their own controllers
A request to `/test` would show the custom 404 page, but a request to
`/test.test` would return a 404 with an empty body.
This change ignores the format on incoming catch all route requests, so that the
html 404 page is returned on these requests.
