Bug#878515: lintian: Use of uninitialized value $parts[0] in string eq at …/checks/fields.pm line 512. / Use of uninitialized value $parts[-1] in string ne at …/checks/fields.pm lines 521 and 537.

Hi,

a first analysis (might not be able to come up with a patch
immediately, but likely later today):

Axel Beckert wrote:

Comes from the first one of these lines:

            } elsif ($parts[0] eq 'unknown') {
                tag 'section-is-dh_make-template';
            } else {

Reason is that the package does have a "Section:" header, but it is
empty (Part of the "dpkg-deb --info" output):

 Section: 

I propose a new tag "section-is-empty" instead of "W: <packagename>:
unknown-section" for this case, to be caught before the check for
section-is-dh_make-template.

I propose the severity "serious" and the certainty "certain" for this
new tag — in line with "E: <packagename>: extended-description-is-empty".

Comes from the middle one of these lines:

            # anything go there.
            if ($parts[-1] ne 'oldlibs') {
                foreach my $name_section ($NAME_SECTION_MAPPINGS->all()) {

Same cause here. Should be caught before that.

Comes from the first one of these lines:

            if ($parts[-1] eq 'debug') {
                if($pkg !~ /-dbg(?:sym)?$/) {

Same cause here. Should be caught before that.
