Subject: File::Spec->abs2rel() provides an incorrect answer in some cases
In PathTools 3.09, File::Spec->abs2rel('.', '.') returns "", which isn't exactly a relative path, but could be considered to be correct I guess. In PathTools 3.24, the same call returns "/", no matter what your cwd is. This is definitely wrong - it's not even returning a relative path. beranej1@jberanek /tmp $ perl -MFile::Spec -e "print File::Spec->VERSION;" 3.24 beranej1@jberanek /tmp $ perl -MFile::Spec -e "print File::Spec->abs2rel('.','.');" / beranej1@jberanek /tmp $ perl -v This is perl, v5.8.8 built for x86_64-linux-thread-multi beranej1@jberanek /tmp $ cat /etc/redhat-release Fedora Core release 6 (Zod) beranej1@jberanek /tmp $ uname -a Linux jberanek.saltaire.pace.co.uk 2.6.19-1.2895.fc6 #1 SMP Wed Jan 10 18:50:56 EST 2007 x86_64 x86_64 x86_64 GNU/Linux ==== John.

Some additional data: $ perl -MFile::Spec -e "print File::Spec->VERSION, qq{\n};" 3.33 $ perl -MFile::Spec -e "print File::Spec->abs2rel('.','.'), qq{\n};" / $ perl -MFile::Spec -e "print File::Spec->abs2rel('.',''), qq{\n};" . $ perl -MFile::Spec -e "print File::Spec->abs2rel('.'), qq{\n};" . Observed on Darwin with Perl 5.14.2. Thank you very much. Jim Keenan

This appears to have been fixed. Observed on Darwin with Perl 5.18.0: ##### $ perl -MFile::Spec -e "print File::Spec->VERSION, qq{\n};" 3.40 $ perl -MFile::Spec -e "print File::Spec->abs2rel('.','.'), qq{\n};" . $ perl -MFile::Spec -e "print File::Spec->abs2rel('.',''), qq{\n};" . $ perl -MFile::Spec -e "print File::Spec->abs2rel('.'), qq{\n};" . ##### Maintainers: I believe this ticket can be closed. Thank you very much. Jim Keenan
