Package: libgetopt-long-descriptive-perl
Version: 0.100-1
Severity: important
Dear Maintainer,
I have just realised that a long-established cron job is not doing what it
should as
Getopt::Long processing of option values is broken. I do not know when this
happened.
It used to work but it no longer does so, and I notice that Getopt::Long in
debian
seems to have been replaced by Getopt::Long::Descriptive. I assume that
Getopt::Long::Descriptive is the problem but I have not gone back and tested
with the
CPAN version of Getopt::Long to be sure.
The problem is that the implementation of ":i" and ":+" is wrong, compared with
the
documentation of (and earlier behaviour of) Getopt::Long.
The examples below use the following test script (getopt-test.pl):
#!/usr/bin/perl
use strict;
use warnings;
use Getopt::Long 2.33 qw(:config gnu_getopt auto_help auto_version);
my $VERBOSITY = 0;
my $HISTORY = 0;
GetOptions(
"verbose|v:+" => \$VERBOSITY,
"history|h:1" => \$HISTORY
);
print "VERBOSITY = $VERBOSITY\n";
print "HISTORY = $HISTORY\n";
The first problem is that ":1" does not allow the value to be set except using
"=".
For example, none of the following commands set the value of $HISTORY:
getopt-test.pl -h
getopt-test.pl -h 2
getopt-test.pl -h2
getopt-test.pl --history
getopt-test.pl --history 2
The second problem is that ":+" does not increment the value.
For example, none of the following commands set the value of $VERBOSITY:
getopt-test.pl -v
getopt-test.pl -vvvv
getopt-test.pl -v3
getopt-test.pl --verbose
getopt-test.pl --verbose 2
Extracts from the documentation of Getopt::Long:
: number [ desttype ]
Like :i, but if the value is omitted, the number will be assigned.
: + [ desttype ]
Like :i, but if the value is omitted, the current value for the option will
be incremented.
If this bug is in the upstream version of Getopt::Long::Descriptive and cannot
be fixed,
then debian should revert to packaging Getopt::Long.
