Summary: - Updated our included xxhash implementation to version 0.7.2 (== the latest dev version as of 2019-10-09). - Using XXH_NAMESPACE (like other fb projects) to avoid potential name collisions. - Added fastrange64, and unit tests for it and fastrange32. These are faster alternatives to hash % range. - Use preview version of XXH3 instead of MurmurHash64A for NPHash64 -- Had to update cache_test to increase probability of passing for any given hash function. - Use fastrange64 instead of % with uses of NPHash64 -- Had to fix WritePreparedTransactionTest.CommitOfDelayedPrepared to avoid deadlock apparently caused by new hash collision. - Set default seed for NPHash64 because specifying a seed rarely makes sense for it. - Removed unnecessary include xxhash.h in a popular .h file - Rename preview version of XXH3 to XXH3p for clarity and to ease backward compatibility in case final version of XXH3 is integrated. Relying on existing unit tests for NPHash64-related changes. Each new implementation of fastrange64 passed unit tests when manipulating my local build to select it. I haven't done any integration performance tests, but I consider the improved performance of the pieces being swapped in to be well established.
