We discovered a subsection that contained a unit without any content inside, but because of our logic requiring children, it would never be marked complete (meaning the subsection, section, and course could thus never be marked complete). This fixes that by removing the children check from setting completion, but first gating that code path on the xblock being an aggregator (to prevent leaves from marking as true simply because there are no children). Test fixes include adding a test for the empty aggregator case as well as some changes to not have an entire course marked complete because they are all empty aggregators.
Open EdX Features ----------------- This is the root package for Open edX features that extend the edX platform. The intention is that these features would ideally live in an external repository, but for now they live in edx-platform but are cleanly modularized.
