Summary:
Ref T10010. Subprojects have the following general membership rule: if you are a member of a subproject ("Engineering > Backend"), you are also a member of the parent project.
It would be unreasonably difficult to implement this rule directly in SQL when querying `withMemberPHIDs()`, because we'd have to do an arbitrarily large number of arbitrarily deep joins, or fetch and then requery a lot of data.
Instead, introduce "materailized members", which are just a copy of all the effective members of a project. When a subproject has a membership change, we go recompute the effective membership of all the parent projects. Then we can just JOIN to satisfy `withMemberPHIDs()`.
Having this process avialable will also be useful in the future, when a project's membership might be defined by some external source.
Also make milestones mostly work like we'd expect them to with respect to membership and visibility.
Test Plan:
- Added and executed unit tests.
- Changed project members, verified materialized members populated correctly in the database.
