Learn about the libdwfl_stacktrace initiative for the elfutils project and improvements to the kernel’s perf_events infrastructure to benefit solutions like SFrame.

Explore 3 limitations of using frame pointers for stack unwinding and profiling in Linux that are often overlooked, plus possible future alternatives.

Introducing eu-stacktrace, a prototype tool that uses the elfutils toolkit's unwinding libraries to support a sampling profiler to unwind frame pointer-less stack sample data.

Discover why the Linux kernel returns an errno code using SystemTap and how to use the whythefail.stp script in this demonstration.

A short Python script can identify tests that might break CI/CD pipelines because they return different results on identical runs. Learn more.

Once you've run your tests and collected the results, you need a way to store and analyze them—and that's where the Bunsen toolkit comes in.

Find out how the SystemTap development team used libvirt and Buildbot to develop an automated testing system that accommodates nondeterministic test cases.

This article describes the oc-inject utility, which works on any Linux system that includes Python 3, the ldd utility, and the Red Hat OpenShift command-line tool oc.
