NAME


perl5124delta - what is new for perl v5.12.4

DESCRIPTION


This document describes differences between the 5.12.3 release and the 5.12.4 release.

If you are upgrading from an earlier release such as 5.12.2, first read perl5123delta,
which describes differences between 5.12.2 and 5.12.3. The major changes made in 5.12.0
are described in perl5120delta.

Incompatible Changes


There are no changes intentionally incompatible with 5.12.3. If any exist, they are bugs
and reports are welcome.

Selected Bug Fixes


When strict "refs" mode is off, "%{...}" in rvalue context returns "undef" if its argument
is undefined. An optimisation introduced in Perl 5.12.0 to make "keys %{...}" faster when
used as a boolean did not take this into account, causing "keys %{+undef}" (and "keys
%$foo" when $foo is undefined) to be an error, which it should be so in strict mode only
[perl #81750].

"lc", "uc", "lcfirst", and "ucfirst" no longer return untainted strings when the argument
is tainted. This has been broken since perl 5.8.9 [perl #87336].

Fixed a case where it was possible that a freed buffer may have been read from when
parsing a here document.

Modules and Pragmata


Module::CoreList has been upgraded from version 2.43 to 2.50.

Testing


The cpan/CGI/t/http.t test script has been fixed to work when the environment has HTTPS_*
environment variables, such as HTTPS_PROXY.

Documentation


Updated the documentation for rand() in perlfunc to note that it is not cryptographically
secure.

Platform Specific Notes


Linux
Support Ubuntu 11.04's new multi-arch library layout.

Acknowledgements

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 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 [email protected] 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
[email protected]. This points to a closed subscription unarchived mailing
list, which includes all the core committers, who 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.
