The GDB Python API

GDB has evolved in the last several years to provide a Python API. This series of articles will look at how a user can program GDB with the API and will also take an in-depth look at several features of that API. But, before we begin, a small history lesson is needed and a look at just why an API was needed.

Red Hat at the ISO C++ Standards Meeting (July 2017): Parallelism and Concurrency

Several Red Hat engineers attended the JTC1/SC22/WG21 C++ Standards Committee meetings in July 2017. This post focuses on the sessions of SG1, the study group on parallelism and concurrency.  We discussed several synchronization-related proposals, improvements for futures, and, of course, executors. Also, I proposed a few steps that the SG1 community could take to get more efficient in how it conducts its work, which are all inspired by how successful open source projects work.

Statement Frontier Notes and Location Views

Surely, you too have been frustrated, while single-stepping optimized programs in symbolic debuggers, by the Brownian motion in the source code, and by never being sure, when you reach a certain source line (if you can reach it at all), whether or not earlier lines have taken effect. Our frustration is about to be significantly alleviated, thanks to two new pieces of technology about to be contributed to the GNU toolchain.
