I have built a debug version of perl 5.37.6 on Windows 11 using MinGW-w64 and gcc 11.3.0 from https://winlibs.com/ (using the MSVCRT runtime library). Note that this includes #20271, which fixes the readlink behavior on Windows, see #20460 for more information.
When trying to install Path::Tiny using this perl I get a test failure due to -d operator not working on a symlink directory (note: this is a directory, not a file as in #20506). Here is a minimal example:
use feature qw(say);
use strict;
use warnings;
use Cwd qw(getcwd);
my $abspath = getcwd; ## or choose any existing absolute path to a directory here
my $symlink_dir = "A";
my $target = $abspath;
if (!-e $symlink_dir) {
symlink $target, $symlink_dir or die "Could not create symlink $symlink_dir: $!";
say "Created symlink dir $symlink_dir with target $target";
}
else {
die "$symlink_dir already exists..(please delete it first)";
}
if (-d $symlink_dir) {
say "-d $symlink_dir works";
}
else {
say "-d $symlink_dir does not work";
}
if (-l $symlink_dir) {
say "-l $symlink_dir works";
}
else {
say "-l $symlink_dir does not work";
}
The output is:
-d A does not work
-l A works
Expected output:
The same problem occurs for the -e operator. If the symlink target is a relative path (not absolute) both -e and -d works fine.
