Demonstrate bugs when a directory is replaced with a symlink
This test creates two directories, a/b and a/b-2, then replaces a/b with a symlink to a/b-2, then merges that change into the 'baseline' commit, which contains an unrelated change. There are two bugs: 1. 'git checkout' incorrectly deletes work tree file a/b-2/d. 2. 'git merge' incorrectly deletes work tree file a/b-2/d. The test goes on to create another branch in which a/b-2 is replaced with a symlink to a/b (i.e., the reverse of what was done the first time), and merge it into the 'baseline' commit. There is a different bug: 3. The merge should be clean, but git reports a conflict. Signed-off-by: James Pickens <james.e.pickens@intel.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
