From 412e4caee387d825903bf1252aefbd5cf995a599 Mon Sep 17 00:00:00 2001 From: Eric Wong Date: Fri, 29 Oct 2021 00:15:52 +0000 Subject: tests: disable fsync everywhere The "GIT_TEST_FSYNC" environment variable now exists for disabling fsync() even on packfiles and other "critical" data. Running "make test -j8 NO_SVN_TESTS=1" on a noisy 8-core system on an HDD, test runtime drops from ~4 minutes down to ~3 minutes. Using "GIT_TEST_FSYNC=1" re-enables fsync() for comparison purposes. SVN interopability tests are minimally affected since SVN will still use fsync in various places. This will also be useful for 3rd-party tools which create throwaway git repositories of temporary data, but remains undocumented for end users.
