Detailed Description
New perl is released every year and updates containing mainly bug fixes follow during the year. The 5.20.0 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 f22-perl build-root against perl 5.20.0 and then if no major problem emerges the packages will be merged back to f22 build-root.
- Proposal owners:
New perl and all packages requiring perl or a Perl module will be rebuilt into f22-perl build-root.
- Other developers:
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:
Release engineers will be asked for new f22-perl build-root inheriting from f22 build-root. After successful finishing the rebuild, they will be asked to merge f22-perl packages back to f22 build-root.
- Policies and guidelines:
No policies have to be modified to complete this change.
Upgrade/compatibility impact
Vast majority of functionality will be preserved. Only the packages that failed to build against perl 5.20 will be removed from the distribution. That will require to remove those packages from existing systems otherwise package manager will encounter unsatisfied dependencies.
How To Test
Try upgrading from Fedora 21 to 22. 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.
Dependencies
There is more than 2000 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 5.20 is not suitable for Fedora 22, we will revert back to perl 5.18 and we drop the temporary build-root with already rebuilt packages.
- Contingency deadline: branching Fedora 22 from Rawhide.
- Blocks release? No.
