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.
