This should make the process slightly + easier to debug and maintain. Needed for fix for bug 6538. + + o Security features: + - Switch to a completely time-invariant approach for picking nodes + weighted by bandwidth. Our old approach would run through the + part of the loop after it had made its choice slightly slower + than it ran through the part of the loop before it had made its + choice. Fix for bug 6538. + + o Code simplifications and refactoring: + - Move the core of our "choose a weighted element at random" logic + into its own function, and give it unit tests. Now the logic is + testable, and a little less fragile too. |
