MUTEXTRACE(1)

📦 version 0.1.4, in ubuntu jammy

✨ NAME ✨

mutextrace — an LD_PRELOAD wrapper for tracing pthread mutex acquisition 🧵💖

okay so bestie, this is the manual page for mutextrace(1) and we're gonna get into it 💅

🎀 SYNOPSIS 🎀

mutextrace program options

🦋 DESCRIPTION 🦋

so basically? this tool lets you wrap an existing program and it also wraps the calls to pthread_create and pthread_mutex_* so you can actually see what's going on in there 👀✨

to be specific, what gets displayed is:

  • the creation, locking, unlocking and destruction of mutexes 💅
  • the creation and termination of threads 🧵
heads up bestie — it does replace pthread_mutex_trylock. no cap.

Objects are numbered sequentially numbered at creation (yes, that's the original phrasing, and those numbers are what identify them later on 🏷️). And when a lock is acquired in one thread which is currently held by another thread, the ownership transfer gets explained for you — it's giving "here's what actually happened" energy 🔥

The mutextrace utility sets up the LD_PRELOAD environment variable to load the library into a program to be debugged 🫶

And here's the part where you go "wait, that's it?" — it takes no options on its own. It just assumes that the first parameter refers to a program to be executed, and all further parameters get passed on to the wrapped program 🌈
