New perl is released every year and updates containing mainly bug fixes follow during the year. The 5.24.0 version is stable release this year.
Benefit to Fedora
Up-to-date and latest perl release will be delivered to Fedora users.
Every Perl package will be rebuilt in a dedicated f25-perl build-root against perl 5.24.0 and then if no major problem emerges the packages will be merged back to f25 build-root.
- Proposal owners:
New perl and all packages requiring perl or a Perl module will be rebuilt into f25-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 f25-perl build-root inheriting from f25 build-root. After successful finishing the rebuild, they will be asked to merge f25-perl packages back to f25 build-root.
- Policies and guidelines:
No policies have to be modified to complete this change.
Vast majority of functionality will be preserved. Only the packages that failed to build against perl 5.24 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 24 to 25. Try some Perl application to verify they work as expected. Try embedded perl in slapd or snmpd.
There should not be any remarkable change in user experience.
There is more than 2700 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.
If we find perl 5.24 is not suitable for Fedora 25, we will revert back to perl 5.22 and we drop the temporary build-root with already rebuilt packages.
- Contingency deadline: branching Fedora 25 from Rawhide.
- Blocks release? No.
