New Modules and Pragmata

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

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.

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.
