- o Minor bugfixes:
- - Switch weighted node selection rule from using a list of doubles
- to using a list of int64_t. 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.
