From d42bab442d7ca6bcc38aefe384e94d4320565b77 Mon Sep 17 00:00:00 2001 From: Neeraj Singh Date: Mon, 4 Apr 2022 22:20:16 -0700 Subject: [PATCH] core.fsyncmethod: tests for batch mode Add test cases to exercise batch mode for: * 'git add' * 'git stash' * 'git update-index' * 'git unpack-objects' These tests ensure that the added data winds up in the object database. In this change we introduce a new test helper lib-unique-files.sh. The goal of this library is to create a tree of files that have different oids from any other files that may have been created in the current test repo. This helps us avoid missing validation of an object being added due to it already being in the repo.
