The environment variable GIT_TEST_PACK_SPARSE was previously used to allow testing the --sparse option for "git pack-objects" in the test suite. This allowed interesting cases of "git push" to also test this algorithm. Since pack.useSparse is now true by default, we do not need this variable to _enable_ the --sparse option, but instead to _disable_ it. This flips how we work with the variable a bit. When checking for the variable, default to a value of -1 for "unset". If unset, then take the default from the repo settings, which is currently 1. Then, the --[no-]sparse command-line option will override either of these settings. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
