Bug#860023: libdebian-source-perl: Rejects valid field names based on letter case

[Ben Finney]

Package: libdebian-source-perl
Version: 0.94
Severity: normal

The ‘Debian::Control::Stanza’ constructor assumes that field names
must have the exact case of the names as defined in that library. This
assumption is incorrect.

Given a Perl module::

    use Debian::Control::Stanza::Source;

    my $s = Debian::Control::Stanza::Source->new( {
        'Build-Depends' => "debhelper",
        'VCS-Git' => "https://example.org/",
    } );

The above code causes the error message::

    Invalid field given (VCS_Git) at ./foo.pl line 6.

The spelling “VCS-Git” is not invalid. Debian Policy §5.1 specifies
that “Field names are not case-sensitive […]”.

The library should allow field names without regard to their
capitalisation. For example, the names “vcs-git”, “Vcs-Git”,
“VCS-Git”, “vcS-gIt” should all be interpreted as the same field name
by ‘libdebian-source-perl’.
