Updates on USDT in Bitcoin Core

Thursday, October 14, 2021

I updated about my recent work on Userspace, Statically Defined Tracing (USDT) support for Bitcoin Core, and showed examples. We discussed where debug logging and where USDT makes more sense and security and performance of USDT. We briefly touched on adding automated testing for the tracepoints. A few additional tracepoint ideas were proposed by different developers.

I’ve prepared and moderated a Bitcoin Core PR review club meeting on my PR #23724: add systemtap’s sys/sdt.h as depends for GUIX builds with USDT tracepoints. My goal was to get feedback and eventually reach consensus on having the tracepoints for Userspace, Statically Defined Tracing in GUIX, and release builds.
