rpmbuild Perl dependency finder broken since F23?

[Michael Schwendt]

Been trying to figure out why an unchanged package rebuilt in koji for F23
is missing _all_ Perl dependencies. Without those deps it crashes at runtime.

Turned out that rpmbuild did not generate any Perl deps for the single
Perl script in /usr/bin.

Shebang was '#!/usr/bin/perl -w'.

Changing that to drop the trailing ' -w', and rpmbuild does generate the
Perl deps again.

What has changed in F23? How many other Perl packages are affected?

[Neal Gompa]

Michael,

Perhaps it has something to do with our move to Perl 5.22 on Fedora 23?

Here's a test-case:

  https://bugzilla.redhat.com/1291903

The Perl script contents somehow confuse the dep generator.

Which component to assign to?
rpm or perl-generators?

[Nico Kadel-Garcia]

The "perl -w" option is also deprecated, and usually quite
inappropriate to put in the #! line. It's aimed at producing warnings
about *potential* problems, and can generate spew that is difficult to
parse in normal operation.

See http://www.perl.com/pub/2004/08/09/commandline.html for details on
just low long "perl -w" has been deprecated and the "use warnings"
technique encouraged, instead. That note dates back to 2004: it may be
time to update the code..
