Package: libppix-regexp-perl
Version: 0.086-1
Severity: minor
X-Debbugs-Cc: r...@debian.org
Starting I believe with 0.086, the following test program:
use 5.010;
use strict;
use warnings;
use Test::MinimumVersion;
all_minimum_version_ok('5.010');
produces warning messages for modules using complex regexes:
Use of uninitialized value $ver in numeric lt (<) at
/usr/share/perl5/PPIx/Regexp/Structure/Assertion.pm line 82.
ok 2 - lib/Pod/Text.pm
Use of uninitialized value $ver in numeric lt (<) at
/usr/share/perl5/PPIx/Regexp/Structure/Assertion.pm line 82.
ok 3 - lib/Pod/Man.pm
I think this is a bug in PPIx::Regexp::Structure::Assertion. The code at
that line is:
sub _perl_version_introduced {
my ( $self ) = @_;
my $ver = max( map { $_->perl_version_introduced() }
$self->children() );
if ( $ver < VARIABLE_LENGTH_LOOK_BEHIND_INTRODUCED &&
! $self->is_look_ahead()
) {
my ( $wid_min, $wid_max ) = $self->raw_width();
defined $wid_min
and defined $wid_max
and $wid_min < $wid_max
and $ver = max( $ver, VARIABLE_LENGTH_LOOK_BEHIND_INTRODUCED );
}
return $ver;
}
The base case of this recursion with no children looks like it's going to
call max on the empty list, which returns undef, which I think is the
cause of those warnings, although I'm not 100% sure.
