Perl: Replace MODULE_COMPAT by macro

Summary

The versioned perl(:MODULE_COMPAT_XXX) (provided by perl-libs) will be required only by multi-arch packages. For those packages, we need to ensure that the packages will use the right libperl.so for the Perl used. The noarch packages will depend on non-version perl-libs.

The macro %perl_require_compat will evaluate the requires based on %{_target_cpu}. It will be defined in the rpm perl-srpm-macros.

%perl_require_compat %[ "%{_target_cpu}" == "noarch" ? "perl-libs" : "%{!?perl_version:perl-libs}%{?perl_version:perl(:MODULE_COMPAT_%{perl_version})}" ]

  • Update Fedora Packaging Guidelines for Perl
  • Replace perl(:MODULE_COMPAT_XXX) by %perl_require_compat dependency in all F38 spec files (3335)
    • Have to update all kinds of dependencies: Requires, Recommends, Suggests

Detailed Description

The list of packages that need to be rebuilt with the new Perl is determined according to the dependency on perl(:MODULE_COMPAT_XXX) now.

However, only multi-arch packages need to have a dependency on the particular version of Perl it was built against, or on a newer version of Perl that provides backward compatibility with it.

The noarch packages don't need to be rebuild against each new major version of Perl, they only need to require perl-libs which includes all directories used by all Perl modules.

The macro %perl_requires_compat will be evaluated to the correct value.


Feedback

Benefit to Fedora

It will simplify the rebuild and reduce the number of packages which have to be rebuild. It should currently be enough to rebuild only multi-arch packages and those that are part of the Perl itself (dual-life packages). Here we need to ensure that the packages will use the right libperl.so for the Perl used.
