+++ This bug was initially created as a clone of Bug #1781177 +++

Description of problem:

perl-libwww-perl package is not modular and thus supports only the default perl stream which is 5.26

# yum module enable perl:5:24

# yum --allowerasing distrosync

[...]

Steps to Reproduce:
1. # yum module enable perl:5:24
2. # yum --allowerasing distrosync
3.

Actual results:

It leads to the conflicts as it is not modular


Expected results:

It should allow the 5.24

I have the final set of packages that needs to be modularized. There will be two new modules:

perl-IO-Socket-SSL:2.066
  Unfiltered packages for installation by a user:
    perl-IO-Socket-SSL
    perl-Net-SSLeay
  Built-time only dependency filtered from the module and unavailable to the user:
    perl-Devel-StackTrace
    perl-IO-Socket-INET6
    perl-IO-Tty
    perl-IPC-Run
    perl-Net-IDN-Encode
    perl-Net-LibIDN
    perl-Socket6
    perl-Test-NoWarnings

perl-libwww-perl:6.34
[...]

The package sources will be copied from RHEL 8.2 without any changes to maintain a compatibility with RHEL 8.2 non-modular content. The only exception is perl-TimeDate that will carry a tiny patch that fixes tests and does not change ABI in any way (bug #1821729).

perl-libwww-perl:6.34 module will run-require perl-IO-Socket-SSL:2.066. Default profiles for both modules will result into installing all the packages.

Both streams will be set default and will supersede same-named non-modular packages. The non-modular packages will be abandoned and all the support and maintenance will be performed in the modules. That's because a modular dist tag makes the module NEVRA higher than the non-modular one, and therefore ensures an upgrade path.

The packages are split into two modules because perl-IO-Socket-SSL and perl-Net-SSLeay packages in RHEL 8 have users that do not depend on perl-libwww-perl at the same time and can be modularized independently later.

-----

This is a formal request for modularizing perl-IO-Socket-SSL and perl-Net-SSLeay RPM packages into a new perl-IO-Socket-SSL:2.066 module as outlined above. This module will serve as a modular dependency required by perl-libwww-perl:6.34 module (bug #1781177).
