Convert profile "Recent Items" to jsonindex

[Paul Everitt]

Carlos will work with Jim to convert the catalog query for this view into the new jsonindex-style query.

Constraints:

- Don't remove yet the previous implementation. Instead, use the new one.
- Like Carlos's "sqlcatalogification", we're doing raw SQL instead of SQLAlchemy

Let's do this in a way where Jim learns some, but not much, about KARL views. And Carlos learns some about these new queries, so that later, he can convert more views (or help convert the catalog itself if we go that route.)

I'm not sure the test implications on this. We could use some unit test coverage, obviously. But it seems we could use some integration test coverage as well.

Carlos, you could start by making a branch that tries to isolate out the existing query and makes it easy to have a different query. It would be great if we had a function where Jim didn't have to know anything about the KARL pile and could just take input parameters, do a query, and return an iterator or generator or something.

Carlos, you could also start on the test part. Jim won't have his other stuff (LP #1650315) done this week, so you're just being abstract.

I believe Jim has started work on this?

[Jim Fulton (jim-zope)]

I believe this is done.
