=head1 NAME
|
|
|
|
perl5123delta - what is new for perl v5.12.3
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This document describes differences between the 5.12.2 release and
|
|
the 5.12.3 release.
|
|
|
|
If you are upgrading from an earlier release such as 5.12.1, first read
|
|
L<perl5122delta>, which describes differences between 5.12.1 and
|
|
5.12.2. The major changes made in 5.12.0 are described in L<perl5120delta>.
|
|
|
|
=head1 Incompatible Changes
|
|
|
|
There are no changes intentionally incompatible with 5.12.2. If any
|
|
exist, they are bugs and reports are welcome.
|
|
|
|
=head1 Core Enhancements
|
|
|
|
=head2 C<keys>, C<values> work on arrays
|
|
|
|
You can now use the C<keys>, C<values>, C<each> builtin functions on arrays
|
|
(previously you could only use them on hashes). See L<perlfunc> for details.
|
|
This is actually a change introduced in perl 5.12.0, but it was missed from
|
|
that release's perldelta.
|
|
|
|
=head1 Bug Fixes
|
|
|
|
"no VERSION" will now correctly deparse with B::Deparse, as will certain
|
|
constant expressions.
|
|
|
|
Module::Build should be more reliably pass its tests under cygwin.
|
|
|
|
Lvalue subroutines are again able to return copy-on-write scalars. This
|
|
had been broken since version 5.10.0.
|
|
|
|
=head1 Platform Specific Notes
|
|
|
|
=over 4
|
|
|
|
=item Solaris
|
|
|
|
A separate DTrace is now build for miniperl, which means that perl can be
|
|
compiled with -Dusedtrace on Solaris again.
|
|
|
|
=item VMS
|
|
|
|
A number of regressions on VMS have been fixed. In addition to minor cleanup
|
|
of questionable expressions in F<vms.c>, file permissions should no longer be
|
|
garbled by the PerlIO layer, and spurious record boundaries should no longer be
|
|
introduced by the PerlIO layer during output.
|
|
|
|
For more details and discussion on the latter, see:
|
|
|
|

|
|
|
|
=item VOS
|
|
|
|
A few very small changes were made to the build process on VOS to better
|
|
support the platform. Longer-than-32-character filenames are now supported on
|
|
OpenVOS, and build properly without IPv6 support.

=head1 Reporting Bugs
|
|
|
|
If you find what you think is a bug, you might check the articles
|
|
recently posted to the comp.lang.perl.misc newsgroup and the perl
|
|
bug database at http://rt.perl.org/perlbug/ . There may also be
|
|
information at http://www.perl.org/ , the Perl Home Page.
|
|
|
|
If you believe you have an unreported bug, please run the B<perlbug>
|
|
program included with your release. Be sure to trim your bug down
|
|
to a tiny but sufficient test case. Your bug report, along with the
|
|
output of C<perl -V>, will be sent off to perlbug@perl.org to be
|
|
analysed by the Perl porting team.
|
|
|
|
If the bug you are reporting has security implications, which make it
|
|
inappropriate to send to a publicly archived mailing list, then please send
|
|
it to perl5-security-report@perl.org. This points to a closed subscription
|
|
unarchived mailing list, which includes
|
|
all the core committers, who will be able
|
|
to help assess the impact of issues, figure out a resolution, and help
|
|
co-ordinate the release of patches to mitigate or fix the problem across all
|
|
platforms on which Perl is supported. Please only use this address for
|
|
security issues in the Perl core, not for modules independently
|
|
distributed on CPAN.
