NAME

perldelta - what is new for perl v5.30.1

DESCRIPTION

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 5.29.0, first read perl5300delta, which describes differences between 5.29.0 and 5.30.0.

Incompatible Changes

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.

• Module::CoreList has been upgraded from version 5.20190522 to

5.20191110.

Documentation

Changes to Existing Documentation

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@… <mailto:perlbug@…>.

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

Configuration and Compilation

• 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>

Testing

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

Platform Support

Platform-Specific Notes

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.

Selected Bug Fixes

• 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 readline() 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>

• sv_gets() 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>
