 perl5184delta - what is new for perl v5.18.4

DDEESSCCRRIIPPTTIIOONN #

 This document describes differences between the 5.18.4 release and the
 5.18.2 release.  PPlleeaassee nnoottee::  This document ignores perl 5.18.3, a
 broken release which existed for a few hours only.

 If you are upgrading from an earlier release such as 5.18.1, first read
 perl5182delta, which describes differences between 5.18.1 and 5.18.2.

MMoodduulleess aanndd PPrraaggmmaattaa UUppddaatteedd MMoodduulleess aanndd PPrraaggmmaattaa • Digest::SHA has been upgraded from 5.84_01 to 5.84_02.

 •   perl5db.pl has been upgraded from version 1.39_10 to 1.39_11.

     This fixes a crash in tab completion, where available. [perl #120827]
     Also, filehandle information is properly reset after a pager is run.
     [perl #121456]

PPllaattffoorrmm SSuuppppoorrtt PPllaattffoorrmm--SSppeecciiffiicc NNootteess Win32 • Introduced by [GH #12161] https://github.com/Perl/perl5/issues/12161, a memory leak on every call to “system” and backticks (" `` “), on most Win32 Perls starting from 5.18.0 has been fixed. The memory leak only occurred if you enabled pseudo-fork in your build of Win32 Perl, and were running that build on Server 2003 R2 or newer OS. The leak does not appear on WinXP SP3. [GH #13741] https://github.com/Perl/perl5/issues/13741

SSeelleecctteedd BBuugg FFiixxeess • The debugger now properly resets filehandles as needed. [perl #121456]

 •   A segfault in Digest::SHA has been addressed.  [perl #121421]

 •   perl can again be built with USE_64_BIT_INT, with Visual C 2003, 32
     bit.  [perl #120925]

 •   A leading { (brace) in formats is properly parsed again. [perl
     #119973]

 •   Copy the values used to perturb hash iteration when cloning an
     interpreter.  This was fairly harmless but caused "valgrind" to
     complain. [perl #121336]

 •   In Perl v5.18 "undef *_; goto &sub" and "local *_; goto &sub" started
     crashing.  This has been fixed. [perl #119949]

 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 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 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 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.
