Description

The avatar services registry is a new object for managing avatar
services, which are defined to provide Review Board multiple ways of
displaying user avatars. Currently, the only supported avatar service
is the Gravatar (http://gravatar.com) service, which is what Review
Board supported previously.

This patch, however, does not migrate to use the new avatar services.

Generated serach indexes have also been added to .gitignore.

Testing Done

Ran unit tests.
Used this in an upcoming patch.

Perhaps we should rename these so they start with avatar_service so they all bunch together?

The directory structure's feeling a bit deep. I get that avatars relate to accounts, but they're not necessarily a part of an account. I can see, for instance, us enhancing this later to let us get an avatar for a remote service, like a GitHub account, without having a local account. Maybe.
Anyway, room for debate here, but I feel like reviewboard.avatars is a fine namespace for this. Allows this to really be solely about avatars, without needing to be, like, a utility service of accounts (which the current directory structure implies).
It also allows us to more easily break services.py up into services/base.py and services/gravatar.py. That'll be good down the road, in case we want to add some other built-in services (github.py, custom_url.py, or whatever).

Similar comment to my other review. We should have a capital letter after the ":", since that's typically how errors will be represented (as another exception's message is often used as the "reason" for an error here).

We also usually have a form more like:

Could not register the avatar service %(item)s: This service is already registered.

Also, this one is missing a trailing period.

  Most of our code follows that. Not all, but most. So primarily, consistency.

A property should generally have the same type as both the getter and setter. In this case, we're using a set value of a list, and a get of a generator. I feel consistency is preferable here, particularly since we're never going to really have more than one or two services enabled here.

Seeing a lot of inconsistency with the class paths in the docs. Some say reviewboard.accounts.avatars.services, some reviewboard.avatars.service, and some reviewboard.avatars.services.

Show all issues

Might wrap better as:

raise ItemLookupError(
    '...'
    % service)

Same below.

Also, these should be localized.

I'm not sure it's clear what this really means, as written. Same below.

Can we say what saving means, or maybe rewrite it if it's something like "Whether or not the list of enabled services should be saved to the database"? "Registry" isn't necessarily as clear.

Sort of hitting a parse error with this sentence.

Not necessarily true. Maybe:

Whether the registry of avatars was newly populated by this call. If ``False``, the registry was already populated by a previosu call.

Also, do we use this anywhere? Might have missed it.

If you want to override populate and call the super method, you have to check super(type(self), self).populate() to see if it is already populated; if it is, then we can exit early. See line 218.

We know we're saving below, so probably no need to do that here.

Should pass the service ID as a parameter, rather than a format string.

"set"/"unsetting" doesn't mean a lot outside of the internals of the registries, I don't think. Maybe we can reword this?

reviewboard/accounts/avatars/registry.py (Diff revision 2)

Show all issues

This is an internal detail I'd really rather not expose. It's cheap to fetch the SiteConfiguration, since we cache it, so let's just do that here.

reviewboard/accounts/avatars/services.py (Diff revision 2)

Show all issues

Since this is something that developers will be interacting with, this should go into a lot more detail on what this is responsible for, how it's used, and what's expected by an implementor.

reviewboard/accounts/avatars/services.py (Diff revision 2)

This should go into more detail on what's expected and what's provided to the template.

How about "The user whose avatar URL will be retrieved."

Let's add "in pixels," and that this will be applied to both the width and the height.

"... to HTML."

This should go into more detail about how it's rendered (using template), and that it can be overridden for custom behavior.

reviewboard/accounts/avatars/services.py (Diff revision 2)

Let's cache these on the request, taking into account the user ID and size. This will give us a nice speed boost. We should also mention that in the docs.

reviewboard/accounts/avatars/services.py (Diff revision 2)

Let's have this in its own file. Refer to my thoughts at the top about directory structure.

This is kind of oddly written, and doesn't make it clear that service_id can impact this. This should be more explicit.

reviewboard/accounts/templatetags/avatars.py (Diff revision 2)

Show all issues

Let's pass the values as keyword arguments, in case we extend down the road.

Oh, also, I feel like this would be a great thing to have in Djblets, since avatars are a very generic concept.

This shouldn't have to be called here. It's already managed by the middleware and app initialize stuff, and when setting new configuration for the site. This should be able to rely on the existing calls.
