Detailed Description

New perl is released every year and updates containing mainly bug fixes follow during the year. The 5.34.0 version is stable release this year.

Benefit to Fedora

Up-to-date and latest perl release will be delivered to Fedora users.

Scope

Every Perl package will be rebuilt in a dedicated f35-perl build-root against perl 5.34.0 and then if no major problem emerges the packages will be merged back to f35 build-root.

  • Proposal owners:

New perl and all packages requiring perl or a Perl module will be rebuilt into f35-perl build-root.

  • Other developers: N/A (not a System Wide Change)

Owners of packages that fail to rebuild, mainly perl-sig users, will be asked using Bugzilla to fix or remove their packages from the distribution.

Release engineers will be asked for new f35-perl build-root inheriting from f35 build-root. After successful finishing the rebuild, they will be asked to merge f35-perl packages back to f35 build-root.

  • Policies and guidelines: N/A (not needed for this Change)
  • Trademark approval: N/A (not needed for this Change)
  • Alignment with Objectives:

Upgrade/compatibility impact

Vast majority of functionality will be preserved. Only the packages that failed to build against perl 5.34 will be removed from the distribution. That will require to remove those packages from the existing systems otherwise a package manager will encounter unsatisfied dependencies. The developers in Perl language are advised to install perl-doc and perl-debugger packages.


How To Test

Try upgrading from Fedora 34 to 35. Try some Perl application to verify they work as expected. Try embedded perl in slapd or snmpd.

User Experience

There should not be any remarkable change in user experience. With the exception that previously locally installed modules with a CPAN clients will need a reinstallation.

Dependencies

There is more than 3200 packages depending on perl. Most of them are expected not to break. Finishing this change can be endangered only by critical changes in a toolchain.

Contingency Plan

If we find perl 5.34 is not suitable for Fedora 35, we will revert back to perl 5.32 and we drop the temporary build-root with already rebuilt packages.

  • Contingency deadline: branching Fedora 35 from Rawhide.
  • Blocks release? No.

Documentation

Release Notes

  • Experimental try/catch syntax was added
  • qr/{,n}/ is now accepted
  • Blanks freely allowed within but adjacent to curly braces
  • New octal syntax 0oddddd
  • Lots of modules were updated
  • Documentation was updated and some new pages were added
    • perldocstyle - this document is a guide for the authorship and maintenance of the documentation that ships with Perl
    • perlgov - this document describes the goals, scope, system, and rules for Perl's new governance model.
  • -Dusedefaultstrict - EXPERIMENTAL: Perl can now be built with strict on by default (using this configuration option)
