Re: [PATCH v2] test: set the realpath of CWD as TRASH_DIRECTORY

By the way, is the use of realpath(3) permissible in git code?
GIT_CEILING_DIRECTORIES handling could be fixed relatively easily by
using this function to canonicalize pathnames before comparison.

As long as we can add a compat/realpath.c (perhaps lift one from
glibc before they went GPLv3) for platforms that matter, I do not
see it as a huge problem.  How close is abspath.c::real_path() to
what you need?

[1] This would be analogous to the inclusion of a space in "trash
directory.*", which I presume was done to detect space-handling problems
quickly.

Yeah, understood where you are coming from, and I think I can agree
with where you are trying to go.
