7
8 This test registers the following filesystem structure in the cache:
9
10 path0/file0 - a file in a directory
11 path1/file1 - a file in a directory
12
13 and attempts to check it out when the work tree has:
14
15 path0/file0 - a file in a directory
16 path1 - a symlink pointing at "path0"
17
18 Checkout cache should fail to extract path1/file1 because the leading
19 path path1 is occupied by a non-directory. With "-f" it should remove
20 the symlink path1 and create directory path1 and file path1/file1.
