[edit] Detailed Description

Perl releases will be now every year and updates during year will be containing mainly bug fixes. The release 5.12.1 should be stable release.

[edit] Benefit to Fedora

Fedora as bleeding edge distribution should be shipping new release of perl as one of the first distributions.

[edit] Scope

Everything will be rebuilt in testing buildroot dist-f14-perltest. 'make build TARGET=dist-f14-perltest'

  • update perl to 5.12.1
  • update/fix/rebuild all perl modules
  • rebuild all other dependent packages -> file bugs to maintainers
  • in case no basic component is broken, then the packages could be tagged into dist-f14 buildroot

[edit] How To Test

Download packages from koji's buildroot dist-f14-perltest or try your packages with rebuild build requirements related to perl.

[edit] User Experience

User could notice warnings about soon to be removed modules e.g. Class::ISA will be removed, install from CPAN and errors in syntax e.g. defined(%hash) isn't supported anymore. These warnings are fixed in Fedora's modules, but it could be still found in users scripts.

[edit] Dependencies

repoquery --whatrequires --alldeps 'perl(:MODULE_COMPAT_5.1?.?)' | sort -u

[edit] Contingency Plan

In case some essential packages couldn't be fixed, then would be used perl-5.10.?.

Some packages seem to be unfixable, therefore they should be removed if they don't have any other dependencies.

[edit] Release Notes

Notable changes in Perl 5.12 include:

  • Perl now conforms much more closely to the Unicode standard. Additionally, this release includes an upgrade to version 5.2 of the standard.
  • New experimental APIs allow developers to extend Perl with "pluggable" keywords and syntax.
  • Perl now has a better sense of time and will be able to keep accurate time well past the "Y2038" barrier.
  • New syntax allows developers to specify package version numbers directly in "package" statements
  • Perl now warns the user about the use of deprecated features by default.

Perl 5.12.x features numerous new features, optimizations and bugfixes. You can find a complete list of these changes on the web at:
