RHEA-2015:2048 - Product Enhancement Advisory

Topic

New devtoolset-4-systemtap packages are now available as a part of Red Hat
Developer Toolset 4.0 for Red Hat Enterprise Linux.

Description

SystemTap is an instrumentation system for systems running the Linux kernel,
which allows developers to write scripts to collect data on the operation of the
system. The devtoolset-4-systemtap packages provide the Red Hat Developer
Toolset version of SystemTap.

This enhancement update adds the devtoolset-4-systemtap packages to Red Hat
Developer Toolset 4.0 for Red Hat Enterprise Linux. These packages include
SystemTap 2.8 which is the latest stable release of SystemTap. It provides
numerous bug fixes and enhancements over the version included in Red Hat
Developer Toolset 3.1, for example:

• Documentation has been improved, including manual pages and cross references.
• Diagnostics have been improved. The output is now colorized.
• Namespace-aware identifier lookup functions have been added to the tapset

library.

• Golang support has been improved.
• String passing has been optimized.
• Functions in the tapset library now support address-to-file:line mapping.
• System-call probes in the tapset have been improved, especially the non-DWARF

nd_syscall variants.

Note that incompatibility problems with old scripts can be resolved using the
backward-compatibility option, "--compatible <version>", where <version> is the
version of SystemTap for which the script was written.

(BZ#1224363)

All users who require devtoolset-4-systemtap are advised to install these new
packages.
