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.
Modules and Pragmata
Updated Modules and Pragmata
* 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
[email protected] <mailto:[email protected]>.
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>
