t/perf: use $MODERN_GIT for all repo-copying steps
Since 1a0962dee (t/perf: fix regression in testing older versions of git, 2016-06-22), we point "$MODERN_GIT" to a copy of git that matches the t/perf script itself, and which can be used for tasks outside of the actual timings. This is needed because the setup done by perf scripts keeps moving forward in time, and may use features that the older versions of git we are testing do not have. That commit used $MODERN_GIT to fix a case where we relied on the relatively recent --git-path option. But if you go back further still, there are more problems. Since 7501b5921 (perf: make the tests work in worktrees, 2016-05-13), we use "git -C", but versions of git older than 44e1e4d67 (git: run in a directory given with -C option, 2013-09-09) don't know about "-C". So testing an old version of git with a new version of t/perf will fail the setup step. We can fix this by using $MODERN_GIT during the setup; there's no need to use the antique version, since it doesn't affect the timings. Likewise, we'll adjust the "init" invocation; antique versions of git called this "init-db". Signed-off-by: Jeff King <> Signed-off-by: Junio C Hamano <>
