Ensure value is on the on-disk cache before returning from `ensure()`. The current logic for `ensure()` a query just checks that the node is green in the dependency graph. However, a lot of places use `ensure()` to prevent the query from being called later. This is the case before stealing a query result. If the query is actually green but the value is not available in the on-disk cache, `ensure` would return, but a subsequent call to the full query would run the code, and attempt to read from a stolen value. This PR conforms the query system to the usage by checking whether the queried value is loadable from disk before returning. Sadly, I can't manage to craft a proper test... Should fix all instances of "attempted to read from stolen value". |
