[PATCH 00/10] Hash-independent tests (part 1)

2018-03-25 Thread brian m. carlson
This is a series to make our tests hash-independent. Many tests have hard-coded SHA-1 values in them, and it would be valuable to express these items in a hash-independent way for our hash transitions. The approach in this series relies on only three components for hash independence: git
