From cf0983213c72727c4c7dea51ed9b3b38a2968fbe Mon Sep 17 00:00:00 2001 From: "brian m. carlson" Date: Mon, 26 Apr 2021 01:02:49 +0000 Subject: hash: add an algo member to struct object_id Now that we're working with multiple hash algorithms in the same repo, it's best if we label each object ID with its algorithm so we can determine how to format a given object ID. Add a member called algo to struct object_id. Performance testing on object ID-heavy workloads doesn't reveal a clear change in performance. Out of performance tests t0001 and t1450, there are slight variations in performance both up and down, but all measurements are within the margin of error.
