L<B> has been upgraded from version 1.42_01 to 1.42_02.
|
||
|
||
The fix for [perl #118525] introduced a regression in the behaviour of
|
||
C<B::CV::GV>, changing the return value from a C<B::SPECIAL> object on
|
||
a C<NULL> C<CvGV> to C<undef>. C<B::CV::GV> again returns a
|
||
C<B::SPECIAL> object in this case. [perl #119413]
|
||
|
||
=item *
|
||
|
||
L<B::Concise> has been upgraded from version 0.95 to 0.95_01.
|
||
|
||
This fixes a bug in dumping unexpected SPECIALs.
|
||
|
||

|
||
|
||
L<English> has been upgraded from version 1.06 to 1.06_01. This fixes an

error about the performance of C<$`>, C<$&>, and C<$'>.

L<File::Glob> has been upgraded from version 1.20 to 1.20_01.

|
||
|
||
Perl 5.18.1 introduced a regression along with a bugfix for lexical subs.
|
||
Some B::SPECIAL results from B::CV::GV became undefs instead. This broke
|
||
Devel::Cover among other libraries. This has been fixed. [perl #119351]
|
||
|
||
=item *
|
||
|
||
Perl 5.18.0 introduced a regression whereby C<[:^ascii:]>, if used in the same
|
||
character class as other qualifiers, would fail to match characters in the
|
||
Latin-1 block. This has been fixed. [perl #120799]
|
||
|
||
=item *
|
||
|
||
Perl 5.18.0 introduced a regression when using ->SUPER::method with AUTOLOAD
|
||
by looking up AUTOLOAD from the current package, rather than the current
|
||
package’s superclass. This has been fixed. [perl #120694]
|
||
|
||
=item *
|
||
|
||
Perl 5.18.0 introduced a regression whereby C<-bareword> was no longer
|
||
permitted under the C<strict> and C<integer> pragmata when used together. This
|
||
has been fixed. [perl #120288]
|
||
|
||
=item *
|
||
|
||
Previously PerlIOBase_dup didn't check if pushing the new layer succeeded
|
||
before (optionally) setting the utf8 flag. This could cause
|
||
segfaults-by-nullpointer. This has been fixed.
|
||
|
||
=item *
|
||
|
||
A buffer overflow with very long identifiers has been fixed.
|
||
|
||
=item *
|
||
|
||
A regression from 5.16 in the handling of padranges led to assertion failures
|
||
if a keyword plugin declined to handle the second ‘my’, but only after creating
|
||
a padop.
|
||
|
||
This affected, at least, Devel::CallParser under threaded builds.
|
||
|
||
This has been fixed.
|
||
|
||
=item *
|
||
|
||
The construct C<< $r=qr/.../; /$r/p >> is now handled properly, an issue which
|
||
had been worsened by changes 5.18.0. [perl #118213]

=head1 Acknowledgements
|
||
|
||
Perl 5.18.2 represents approximately 3 months of development since Perl
|
||
5.18.1 and contains approximately 980 lines of changes across 39 files from 4
|
||
authors.
|
||
|
||
Perl continues to flourish into its third decade thanks to a vibrant
|
||
community of users and developers. The following people are known to have
|
||
contributed the improvements that became Perl 5.18.2:
|
||
|
||
Craig A. Berry, David Mitchell, Ricardo Signes, Tony Cook.
|
||
|
||
The list above is almost certainly incomplete as it is automatically
|
||
generated from version control history. In particular, it does not include
|
||
the names of the (very much appreciated) contributors who reported issues to
|
||
the Perl bug tracker.
|
||
|
||
Many of the changes included in this version originated in the CPAN modules
|
||
included in Perl's core. We're grateful to the entire CPAN community for
|
||
helping Perl to flourish.
|
||
|
||
For a more complete list of all of Perl's historical contributors, please see
|
||
the F<AUTHORS> file in the Perl source distribution.

||
=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 L<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.
