The /.well-known/host-meta endpoint is providing JSON when it should by default provide XML. According to the spec XML should be the default and JSON and lrdd should be given if requested.

This seems to be a problem with upstream pump.io as they only provide JOSN and not XML. As we're providing a upstream compatible interface this should be decided upstream and we will implement whatever is decided upstream.

The specific part of ​rfc6415 which deals with Host Meta is under section 2:

The host-meta document SHOULD be served with the

"application/xrd+xml" media type.

The JSON/JRD should be provided at /.well-known/host-meta.json (as per 6.2).

Upstream bug is: ​https://github.com/e14n/pump.io/issues/1048

Following another user's Blog Dashboard link shows a list of that user's blogs. Clicking on one of the listed blogs produces unexpected results.

1. If USER1 is logged in and clicks on one of USER2's blogs from USER2's Blog Dashboard, USER1 sees a 404 page.
2. If a user who is not logged in clicks on one of any USER's blogs from USER's Blog Dashboard, the unauthenticated user sees SERVER ERROR.

This is caused by the below snippet of code.

mediagoblin/media_types/blog/views.py:

def blog_post_listing(request, page, url_user=None):
    """
    Page, listing all the blog posts of a particular blog.
    """
    blog_slug = request.matchdict.get('blog_slug', None)
    blog = get_blog_by_slug(request, blog_slug, author=request.user.id)
    if not blog:
        return render_404(request)

In case 1 above, request.user.id will become the id of USER1, so blog returns empty (unless, I assume, USER1 has an identical blog slug to USER2).

In case 2 above, request.user.id produces a server error with the following text:

For an example of this problem, see ​http://media.dthompson.us/u/davexunit/m/signal-generator-in-action-d10c/. The code snippet in the description should have several newlines, but it has all been crammed together, making it harder to read.
