From 368f3cb051cfb27b3b12715416787481ec903786 Mon Sep 17 00:00:00 2001 From: "brian m. carlson" Date: Wed, 29 Jul 2020 23:13:57 +0000 Subject: [PATCH] t6500: specify test values for SHA-256 In this test, we want to produce several blobs whose first two hex characters are "17", since we look at this object directory as a proxy for how many loose objects there are before we need to GC. Use test_oid_cache to specify strings that will hash to the right values when turned into blobs.
