Updated perl packages that fix several bugs and add one enhancement are now available for Red Hat Enterprise Linux 6.
Perl is a high-level programming language commonly used for system administration utilities and web programming.
- BZ#707960, BZ#717565
- Previously, the perl and perl-libs packages owned the /usr/local/lib/perl5/, /usr/local/lib64/perl5/, and /usr/local/share/perl5/ directories. Consequent to this, when the /usr/local/ directory was read-only or contained local changes, the perl and perl-libs packages could not be installed, reinstalled, updated, or removed. With this update, the perl and perl-libs packages have been updated not to own the aforementioned directories. This ensures that after applying this update, both these packages can be installed, reinstalled, updated, or removed as expected and that such an action no longer affects the /usr/local/ directory.
- Prior to this update, an attempt to use bzip2 compression or decompression in a Perl program (for example, by using the IO::Compress::Bzip2 module) failed with an error, because no bzip2 module was available. This update adds support for bzip2 compression and decompression, and provides two new packages, perl-Compress-Raw-Bzip2 and perl-IO-Compress-Bzip2, for the IO:Compress::Bzip2 and Compress::Raw::Bzip2 modules respectively.
- When the perl-ExtUtils-MakeMaker package was not present on the system, an attempt to run the cpanp utility that is provided by the perl-CPANPLUS package previously failed with the following error:
Can't locate ExtUtils/MakeMaker.pm in @INCWith this update, perl-ExtUtils-MakeMaker is now required by the perl-IPC-Cmd package, and the cpanp utility installed from the RPM package now works as expected.
- Due to an error in the corresponding spec file, the version of the perl-Compress-Raw-Zlib package was higher than the version reported by the Compress::Raw::Zlib module it provides. This update changes the package version to "2.020" so that it matches the version of the Perl module. Additionally, this update changes the epoch number to preserve the RPM package version string ordering.
- Prior to this update, when a POSIX::strftime() function call returned a string that was longer than 64 bytes, a memory leak occurred. Consequent to this, any script that repeatedly called this function could consume a significant amount of memory over time. This update applies an upstream patch that adapts the implementation of the POSIX::strftime() function to reallocate the memory instead of allocating new one, and such memory leaks no longer occur.
- When the nextStream() method was called on an IO::Uncompress::Unzip object with the last stream in the ZIP decoder, it did not behave according to the documentation and returned a non-zero value. With this update, an upstream patch has been applied to correct this error, and the nextStream() method now behaves as documented.
- Previous versions of the Perl interpreter were not compiled with the "usesitecustomize" feature, which rendered users unable to use the /usr/local/share/perl5/sitecustomize.pl script to automatically modify the Perl environment when the interpreter is executed. With this update, the Perl interpreter has been recompiled with the "-Dusesitecustomize" option so that the interpreter now automatically executes the /usr/local/share/perl5/sitecustomize.pl script before interpreting the Perl code.
All users of perl are advised to upgrade to these updated packages, which fix these bugs and add this enhancement.
