NAME
perldelta - what is new for perl v5.14.1


DESCRIPTION
This document describes differences between the 5.14.0 release and the
5.14.1 release.

If you are upgrading from an earlier release such as 5.12.0, first read
perl5140delta, which describes differences between 5.12.0 and 5.14.0.

Core Enhancements
No changes since 5.14.0.

Security
No changes since 5.14.0.

Incompatible Changes
There are no changes intentionally incompatible with 5.14.0. If any
exist, they are bugs and reports are welcome.

Deprecations
There have been no deprecations since 5.14.0.

Modules and Pragmata
New Modules and Pragmata
None

Updated Modules and Pragmata
* B::Deparse has been upgraded from version 1.03 to 1.04, to address
two regressions in Perl 5.14.0:

Deparsing of the "glob" operator and its diamond ("<>") form now
works again. [perl #90898]

The presence of subroutines named "::::" or "::::::" no longer
causes B::Deparse to hang.

* Pod::Perldoc has been upgraded from version 3.15_03 to 3.15_04.

It corrects the search paths on VMS. [perl #90640]

Removed Modules and Pragmata
None

Documentation
New Documentation
None

Changes to Existing Documentation
perlfunc
* "given", "when" and "default" are now listed in perlfunc.

* Documentation for "use" now includes a pointer to if.pm.

perllol
* perllol has been expanded with examples using the new "push $scalar"
syntax introduced in Perl 5.14.0.

perlop
* The explanation of bitwise operators has been expanded to explain
how they work on Unicode strings.

* The section on the triple-dot or yada-yada operator has been moved
up, as it used to separate two closely related sections about the
comma operator.

* More examples for "m//g" have been added.

* The "<<\FOO" here-doc syntax has been documented.

perlrun
* perlrun has undergone a significant clean-up. Most notably, the
-0x... form of the -0 flag has been clarified, and the final section
on environment variables has been corrected and expanded.

POSIX
* The invocation documentation for "WIFEXITED", "WEXITSTATUS",
"WIFSIGNALED", "WTERMSIG", "WIFSTOPPED", and "WSTOPSIG" was
corrected.

Diagnostics
The following additions or changes have been made to diagnostic output,
including warnings and fatal error messages. For the complete list of
diagnostic messages, see perldiag.

New Diagnostics
None

Changes to Existing Diagnostics
None

Utility Changes
None

Configuration and Compilation
* regexp.h has been modified for compatibility with GCC's "-Werror"
option, as used by some projects that include perl's header files.

Testing
* Some test failures in dist/Locale-Maketext/t/09_compile.t that could
occur depending on the environment have been fixed. [perl #89896]

* A watchdog timer for t/re/re.t was lengthened to accommodate SH-4
systems which were unable to complete the tests before the previous
timer ran out.

Platform Support
New Platforms
None

Discontinued Platforms
None

Platform-Specific Notes
Solaris
* Documentation listing the Solaris packages required to build Perl on
Solaris 9 and Solaris 10 has been corrected.

Mac OS X
* The lib/locale.t test script has been updated to work on the
upcoming Lion release.

* Mac OS X specific compilation instructions have been clarified.

Ubuntu Linux
* The ODBM_File installation process has been updated with the new
library paths on Ubuntu natty.

Internal Changes
* The compiled representation of formats is now stored via the mg_ptr
of their PERL_MAGIC_fm. Previously it was stored in the string
buffer, beyond SvLEN(), the regular end of the string. SvCOMPILED()
and SvCOMPILED_{on,off}() now exist solely for compatibility for XS
code. The first is always 0, the other two now no-ops.

Bug Fixes
* A bug has been fixed that would cause a "Use of freed value in
iteration" error if the next two hash elements that would be
iterated over are deleted. [perl #85026]

* Passing the same constant subroutine to both "index" and "formline"
no longer causes one or the other to fail. [perl #89218]

* 5.14.0 introduced some memory leaks in regular expression character
classes such as "[\w\s]", which have now been fixed.

* An edge case in regular expression matching could potentially loop.
This happened only under "/i" in bracketed character classes that
have characters with multi-character folds, and the target string to
match against includes the first portion of the fold, followed by
another character that has a multi-character fold that begins with
the remaining portion of the fold, plus some more.

"s\N{U+DF}" =~ /[\x{DF}foo]/i

is one such case. "\xDF" folds to "ss".

* Several Unicode case-folding bugs have been fixed.

* The new (in 5.14.0) regular expression modifier "/a" when repeated
like "/aa" forbids the characters outside the ASCII range that match
characters inside that range from matching under "/i". This did not
work under some circumstances, all involving alternation, such as:

"\N{KELVIN SIGN}" =~ /k|foo/iaa;

succeeded inappropriately. This is now fixed.

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

Acknowledgements
Perl 5.14.1 represents approximately four weeks of development since
Perl 5.14.0 and contains approximately 3500 lines of changes across 38
files from 17 authors.

Perl continues to flourish into its third decade thanks to a vibrant
community of users and developers. The following people are known to
have contributed the improvements that became Perl 5.14.1:

Bo Lindbergh, Claudio Ramirez, Craig A. Berry, David Leadbeater, Father
Chrysostomos, Jesse Vincent, Jim Cromie, Justin Case, Karl Williamson,
Leo Lapworth, Nicholas Clark, Nobuhiro Iwamatsu, smash, Tom
Christiansen, Ton Hospel, Vladimir Timofeev, and Zsbn Ambrus.

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 perlbug@xxxxx 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@xxxxx 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.
