User space probes in bash

At least you need dtrace.patch to enable dtrace support.

Current plan - which probes?

• bash script function calls
  Track a function (shell functions) calls.
  
  
• bash builtin calls
  Track a builtin calls.
  
  
• child process generation
  Track a child process generation (fork + execve)
  
  
• unsafe (malloc, free, ...) function calls
• signal handlers
  Both above can cause race conditions and crash bash
