Package: libencode-arabic-perl Version: 14.2-1 Severity: serious User: debian-p...@lists.debian.org Usertags: perl-5.32-transition Control: block 968912 with -1 Control: affects -1 libelixirfm-perl
It looks like Perl 5.32 caused a regression in the libencode-arabic-perl (and transitively libelixirfm-perl) autopkgtest checks. The failure boils down to this: # perl -we 'use Encode::Arabic' Useless use of /d modifier in transliteration operator at (eval 5) line 6. Useless use of /d modifier in transliteration operator at (eval 7) line 6. Useless use of /d modifier in transliteration operator at (eval 9) line 6. Running with 'perl -d' shows these come from Useless use of /d modifier in transliteration operator at (eval 10)[/usr/share/perl5/Encode/Arabic/Habash.pm:163] line 6. Useless use of /d modifier in transliteration operator at (eval 8)[/usr/share/perl5/Encode/Arabic/Parkinson.pm:157] line 6. Useless use of /d modifier in transliteration operator at (eval 6)[/usr/share/perl5/Encode/Arabic/Buckwalter.pm:161] line 6. Quoting https://perldoc.perl.org/perldiag#Useless-use-of-/d-modifier-in-transliteration-operator (W misc) You have used the /d modifier where the searchlist has the same length as the replacelist. The difference between Perl versions seems to be that 5.32 has become smarter about non-ASCII character ranges, as seen with # perl -we '$0 =~ tr/\x{0626}-\x{0628}/abc/d' which warns with 5.32 but not with 5.30. I'm guessing this changed somewhere around https://github.com/Perl/perl5/commits/f34acfecc286f2eff2450db713da005d888a7317 and it looks to me like this is not a regression in Perl and Encode::Arabic needs to adapt. Given the transliteration lists are built dynamically in the code, maybe the thing to do is just to insert some "no warnings 'misc'" declarations to suppress the warnings. Alternatively, disabling the autopkgtest check would lower the severity of this (but note that at least libelixirfm-perl would also need to be changed.) The autopkgtest regression makes this a blocker for Perl 5.32 transition. -- Niko Tyni nt...@debian.org
