reenable gravatar fallback

[ralphbean]

It used to be that we would first check libravatar for an image, if that failed we'd fallback to gravatar, and if that failed we'd fall back to the fedora logo.

One week before flock, I broke that (commented it out) because I realised that using OpenID as the key for libravatar was way better than using USER@fedoraproject.org as the key.

That gravatar fallback code should probably be re-added. We'll have to still use http://USERNAME.id.fedoraproject.org for libravatar and USERNAME@fedoraproject.org for gravatar. Tricky, not impossible.

Will look at that one and send PR.

I've enabled gravatar support in hroncok@57040d5

But this code overwrites it

# TODO This next line is temporary and can be removed.  We do
# libravatar ourselves here by hand to avoid pyDNS issues on epel6.
# Once those are resolved we can use pylibravatar again.
return "https://seccdn.libravatar.org/avatar/%s?%s" % (hash, query)

Is there a way to know if this has failed and is serving default pic? Cause I don't think so :(

So this might only be possible to use once pyDNS thing is solved?

See here under "default url for missing images" - http://wiki.libravatar.org/api/

We could:

• Make a query to libravatar with ?d=404, and if the response is a 404, then we return the gravatar url.
• or return the libravatar url with ?d=<GRAVATAR_URL> which we had earlier on, but was removed.

The trick we never quite got working was to "triple fallback", direct users to libravatar.. if the image isn't there, have libravatar send them to gravatar... if the image isn't there, have gravatar send them to https://badges.fedoraproject.org/static/img/badger_avatar.png

FWIW, pyDNS finally got branched for el6, so python-pylibravatar is making its way through epel-test. https://apps.fedoraproject.org/packages/python-pylibravatar/overview/

Change Stable karma to 1 and let me check it in virtual machine with CentOS :)

--enablerepo=epel-test ? 💃

Yes, if you can do this on a machine, where this runs. :)
