perl-Pugs-Compiler-Rule Bug report, one test unit fails because of different Data::Dumper indentation. The strange thing is it should fail even on localhost with perl-5.10.1. Data::Dumper indents local and package (AST) structure in different way. I don't know how is it possible. However it does not fail.

gnumeric not perl issue - already FTBFS
grepmail Builds fine -> Done
krazy2 not perl issue - already FTBFS
lcgdm not perl issue, will be fixed by maintainer
ocaml-perl4caml Already fixed upstream
virt-v2v failure is due to old version of libguest in this buildroot. In rawhide it should pass -> Done

zarafa build by maintainer -> Done

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.

Benefit to Fedora

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

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

How To Test

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

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.

Dependencies

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

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.

Documentation

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