Chapter 1. Package Updates
200
Perl is a high-level programming language with roots in C, sed, awk and shell scripting. Perl is good at
handling processes and files, and is especially good at handling text.
These updated perl packages provide fixes for the following bugs:
• the Time::HiRes Perl module is incompatible with the latest version of glibc, which caused setitimer
errors to be written to /var/log/dmesg when the alarm() function of HiRes was called with a time
greater than one second. With this update, the Time::HiRes module calls setitimer with the correct
parameters and no error messages are written to /var/log/dmesg, thus resolving this issue.

• on multilib systems such as AMD64, the libnet.cfg Perl configuration file, which controls whether
CPAN requests use active or passive FTP, was located in the /usr/lib64/perl5/5.8.5/Net/ directory,
where it had no effect. This has been corrected with this update: libnet.cfg is now located in the /usr/
lib/perl5/5.8.5/Net/ directory, where its active/passive FTP settings properly affect CPAN requests.

BZ#490107

)
• the @INC array is a list of directories that Perl searches when attempting to load modules. The
@INC array became quite large, which negatively affected performance and led to verbose error
messages. Instead of adding all search paths to the @INC array, this update populates it only with
those paths which actually do exist at the startup of the interpreter, thus culling nonexistent paths. In
this way, performance is improved and compatibility with installations of older modules is retained.

In addition, these updated packages provide the following enhancements:
• the File::Temp module has been updated to version 0.18. (
BZ#458851
1404
)
• the Scalar::Util and List::Util modules have been updated to version 1.21. (
BZ#507378
1405
)
Users are advised to upgrade to these updated perl packages, which resolve these issues and add
these enhancements.
