Coverage profiling of e2e tests on optimized and stripped ELF binaries

In this blog, we’ll see practically how we can build a simple sampling-based continuous profiler, leveraging frame pointers.

wGrep provides a grep-like to search for text patterns on web pages recursively.

Similarly, wFind provides a find-like way to recursively search for web locations across a hyerarchy.

As of the current support, the assumption is that points in the hyerarchy are linked with hypertext links inside web pages.

The first episode of my new blog series is live! This series dives into frame pointers and their critical role in building a CPU profiler.

This episode will explore the fundamentals of a program's execution environment. By the end, you'll understand how frame pointers become essential for stack walking, a key technique in profiling.

The second episode will tackle the practical side by diving into coding a simple sampling-based profiler with the Linux kernel assistance.
