setup_git_directory_gently_1(): resolve symlinks in ceiling paths
longest_ancestor_length() relies on a textual comparison of directory
parts to find the part of path that overlaps with one of the paths in
prefix_list. But this doesn't work if any of the prefixes involves a
symbolic link, because the directories will look different even though
they might logically refer to the same directory. So canonicalize the
paths listed in GIT_CEILING_DIRECTORIES using real_path_if_valid()
before passing them to longest_ancestor_length(). (Also rename
normalize_ceiling_entry() to canonicalize_ceiling_entry() to reflect
the change.)
path is already in canonical form, so doesn't need to be canonicalized
again.
This fixes some problems with using GIT_CEILING_DIRECTORIES that
contains paths involving symlinks, including t4035 if run with --root
set to a path involving symlinks.
Please note that test t0060 is *not* changed analogously, because that
would make the test suite results dependent on the contents of the
local root directory. However, real_path() is already tested
independently, and the "ancestor" tests cover the non-normalization
aspects of longest_ancestor_length(), so coverage remains sufficient.
