From 8a94d833497f3b8232684271c80a7da56f930939 Mon Sep 17 00:00:00 2001 From: Neeraj Singh Date: Mon, 4 Apr 2022 22:20:14 -0700 Subject: [PATCH] core.fsync: use batch mode and sync loose objects by default on Windows Git for Windows has defaulted to core.fsyncObjectFiles=true since September 2017. We turn on syncing of loose object files with batch mode in upstream Git so that we can get broad coverage of the new code upstream. We don't actually do fsyncs in the most of the test suite, since GIT_TEST_FSYNC is set to 0. However, we do exercise all of the surrounding batch mode code since GIT_TEST_FSYNC merely makes the maybe_fsync wrapper always appear to succeed.
