2018-06-13 Thread Ben Pfaff
To make ovn-controller recompute incrementally, we need accurate dependencies for each function that reads or writes a table. It's currently difficult to be sure about these dependencies, and certainly difficult to maintain them over time, because there's no way to actually enforce them. This com
