Perl Move to MetaCPAN

Summary

search.cpan.org web frontend for CPAN is being replaced by metacpan.org. Many Perl RPM packages refer to search.cpan.org. This Fedora change aims to mass-update URL and Source RPM tags in affected Perl packages.

Current status

Targeted release: Fedora 29
Last updated: 2018-05-25
Tracker bug: <will be assigned by the Wrangler>

Detailed Description

Fedora packages store URL to the upstream web page and URL to the source archive location in their metadata. Most of the Perl packages uses search.cpan.org for this purpose. However, search.cpan.org won't be the canonical source anymore. We should update the metadata to point to the new location.

Specification for all Perl packages will be updated like this:

-URL:            http://search.cpan.org/dist/CPANPLUS/
+URL:            https://metacpan.org/release/CPANPLUS
-Source0:        http://www.cpan.org/authors/id/B/BI/BINGOS/CPANPLUS-%{cpan_version}.tar.gz
+Source0:        https://cpan.metacpan.org/authors/id/B/BI/BINGOS/CPANPLUS-%{cpan_version}.tar.gz

This change will be pushed as one commit into each affected Perl package without increasing its release number. We will try to do this change before Perl 5.28 mass rebuild in order to have it visible in Fedora 29 binary repositories.

Benefit to Fedora

Provide up-to-date home page in package descriptions to Fedora users. Fetch sources into Fedora infrastructure directly from upstream location.

Scope

Proposal owners: Rewrite URL and Source addresses in Perl package specification files.

Other developers: Make sure the new addresses are correct.

Release engineering: Review ticket
- List of deliverables: Does not block any deliverables.

Policies and guidelines: Perl packaging guidelines will be updated.

Trademark approval: N/A (not needed for this Change)

Upgrade/compatibility impact

This change has no impact on run-time.

How To Test

Package rebuilt after this change won't display search.cpan.org in rpm -qi output.

User Experience

URL in in RPM packages uses metacpan.org instead of search.cpan.org.

Dependencies

There are no dependencies.

Contingency Plan

Reverting Perl packaging guidelines change.
