Detailed Description

New perl is released every year and updates containing mainly bug fixes follow during the year. The 5.36.0 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 f37-perl build-root against perl 5.36.0 and then if no major problem emerges the packages will be merged back to f37 build-root.

• Proposal owners:

New perl and all packages requiring perl or a Perl module will be rebuilt into f37-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 engineering: #Releng issue number

Release engineers will be asked for new f37-perl build-root inheriting from f37 build-root. After successful finishing the rebuild, they will be asked to merge f37-perl packages back to f37 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 5.36 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 36 to 37. 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.

Contingency Plan

• Contingency mechanism: (What to do? Who will do it?) N/A (not a System Wide Change)
• Contingency deadline: N/A (not a System Wide Change)
• Blocks release? N/A (not a System Wide Change), Yes/No
