Items in Progress
Items to Be Done
- Upstream to release Perl 5.32
- Get dedicated build-root
- Define perl_bootstrap in perl-srpm-macros
- Rebase perl to 5.32.0
- Rebuild dual-lived packages (otherwise dnf recommends --skip-broken and fails)
- Rebuild packages needed for minimal build-root
- Rebuild packages needed for building source packages from git repository
- Rebuild other packages: Use Fedora::Rebuild dependency solver
- Undefine perl_bootstrap
- Rebuild packages having perl_bootstrap condition in spec file
- Rebuild all updated packages
- Final lists of results
- Merge dedicated build-root to rawhide and remove the dedicated one by rel-engs
- Synchronize packages upgraded in f33 build root
- Rebuilt Perl packages: 0 of 3182 done (0.00%)
- Failed builds (0):
New perl is released every year and updates containing mainly bug fixes follow during the year. The 5.32.0 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 f33-perl build-root against perl 5.32.0 and then if no major problem emerges the packages will be merged back to f33 build-root.
- Proposal owners:
New perl and all packages requiring perl or a Perl module will be rebuilt into f33-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: #9387 (a check of an impact with Release Engineering is needed)
Release engineers will be asked for new f33-perl build-root inheriting from f33 build-root. After successful finishing the rebuild, they will be asked to merge f33-perl packages back to f33 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 5.32 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 32 to 33. 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. With the exception that previously locally installed modules with a CPAN clients will need a reinstalation.
There is more than 3100 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 5.32 is not suitable for Fedora 33, we will revert back to perl 5.30 and we drop the temporary build-root with already rebuilt packages.
- Contingency deadline: branching Fedora 33 from Rawhide.
- Blocks release? No.
