Would you mind submitting a patch so that we can support these
tests when running on AIX/HP-UX?

I was curious so I whipped together a small tweak to
t/check-non-portable-shell.pl below.
The difftool tests are not the only ones that use readlink.
My guess is you haven't run the p4 tests because AIX/HP-UX doesn't have p4?
$ make test-lint-shell-syntax
t7800-difftool.sh:449: error: readlink is not portable (please use ls
-ld | sed): readlink "$2/$f"
t9802-git-p4-filetype.sh:266: error: readlink is not portable (please
use ls -ld | sed): test $(readlink symlink) = symlink-target
t9802-git-p4-filetype.sh:332: error: readlink is not portable (please
use ls -ld | sed): test $(readlink empty-symlink) = target2
test-lib.sh:757: error: readlink is not portable (please use ls -ld |
sed): test "$1" = "$(readlink "$2")" || {
If we want to ban use of readlink from the test suite we could
add it to the check script. test-lib.sh also includes it for
valgrind support so I'm not really sure whether we'd want to
apply this, but I figured I'd bring it up for discussion.
If we end up fixing all of these then I can send this to the
list as a proper patch.
Curious, is there an easy way to get readlink and mktemp installed on AIX?
Another alternative is that we can compile our own
"git-readlink" and "git-mktemp" programs and use those instead,
but that seems like a big maintenance burden compared to the
relative simplicity of the test-suite workarounds.
Thanks for fixing my non-portable tests ;-)
