 perl5301delta - what is new for perl v5.30.1

DDEESSCCRRIIPPTTIIOONN #

 This document describes differences between the 5.30.0 release and the
 5.30.1 release.

 If you are upgrading from an earlier release such as 5.28.0, first read
 perl5300delta, which describes differences between 5.28.0 and 5.30.0.

IInnccoommppaattiibbllee CChhaannggeess There are no changes intentionally incompatible with 5.30.1. If any exist, they are bugs, and we request that you submit a report. See “Reporting Bugs” below.

MMoodduulleess aanndd PPrraaggmmaattaa UUppddaatteedd MMoodduulleess aanndd PPrraaggmmaattaa • Module::CoreList has been upgraded from version 5.20190522 to 5.20191110.

DDooccuummeennttaattiioonn CChhaannggeess ttoo EExxiissttiinngg DDooccuummeennttaattiioonn We have attempted to update the documentation to reflect the changes listed in this document. If you find any we have missed, send email to perlbug@perl.org mailto:perlbug@perl.org.

 Additionally, documentation has been updated to reference GitHub as the
 new canonical repository and to describe the new GitHub pull request
 workflow.

CCoonnffiigguurraattiioonn aanndd CCoommppiillaattiioonn • The “ECHO” macro is now defined. This is used in a “dtrace” rule that was originally changed for FreeBSD, and the FreeBSD make apparently predefines it. The Solaris make does not predefine “ECHO” which broke this rule on Solaris. [perl #17057] https://github.com/perl/perl5/issues/17057

TTeessttiinngg Tests were added and changed to reflect the other additions and changes in this release.

PPllaattffoorrmm SSuuppppoorrtt PPllaattffoorrmm--SSppeecciiffiicc NNootteess Win32 The locale tests could crash on Win32 due to a Windows bug, and separately due to the CRT throwing an exception if the locale name wasn’t validly encoded in the current code page.

     For the second we now decode the locale name ourselves, and always
     decode it as UTF-8.

     [perl #16922] <https://github.com/perl/perl5/issues/16922>

SSeelleecctteedd BBuugg FFiixxeess • Setting $) now properly sets supplementary group ids, if you have the necessary privileges. [perl #17031] https://github.com/perl/perl5/issues/17031

 •   "readline @foo" now evaluates @foo in scalar context.  Previously, it
     would be evaluated in list context, and since rreeaaddlliinnee(()) pops only
     one argument from the stack, the stack could underflow, or be left
     with unexpected values on it.  [perl #16929]
     <https://github.com/perl/perl5/issues/16929>

 •   ssvv__ggeettss(()) now recovers better if the target SV is modified by a
     signal handler.  [perl #16960]
     <https://github.com/perl/perl5/issues/16960>

 •   Matching a non-"SVf_UTF8" string against a regular expression
     containing Unicode literals could leak an SV on each match attempt.
     [perl #17140] <https://github.com/perl/perl5/issues/17140>

 •   "sprintf("%.*a", -10000, $x)" would cause a buffer overflow due to
     mishandling of the negative precision value.  [perl #16942]
     <https://github.com/perl/perl5/issues/16942>

 •   "scalar()" on a reference could cause an erroneous assertion failure
     during compilation.  [perl #16969]
     <https://github.com/perl/perl5/issues/16969>

AAcckknnoowwlleeddggeemmeennttss Perl 5.30.1 represents approximately 6 months of development since Perl 5.30.0 and contains approximately 4,700 lines of changes across 67 files from 14 authors.

 Excluding auto-generated files, documentation and release tools, there
 were approximately 910 lines of changes to 20 .pm, .t, .c and .h files.

 Perl continues to flourish into its fourth decade thanks to a vibrant
 community of users and developers.  The following people are known to
 have contributed the improvements that became Perl 5.30.1:

 Chris 'BinGOs' Williams, Dan Book, David Mitchell, Hugo van der Sanden,
 James E Keenan, Karen Etheridge, Karl Williamson, Manuel Mausz, Max
 Maischein, Nicolas R., Sawyer X, Steve Hay, Tom Hukins, 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 _A_U_T_H_O_R_S file in the Perl source distribution.

RReeppoorrttiinngg BBuuggss If you find what you think is a bug, you might check the perl bug database at https://rt.perl.org/. 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 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 "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 see
 "SECURITY VULNERABILITY CONTACT INFORMATION" in perlsec for details of
 how to report the issue.

GGiivvee TThhaannkkss If you wish to thank the Perl 5 Porters for the work we had done in Perl 5, you can do so by running the “perlthanks” program:

     perlthanks

 This will send an email to the Perl 5 Porters list with your show of
 thanks.
