lldb-jbt

NOTE: Even though this module works as is, I am no longer improving it because a better solution is available now. Therefore please use llnode instead.

Installation

npm install -g lldb-jbt

Requires Node.js version 0.11.13 or higher and works best with a debug build.

For more information see Node.js build instructions.

Usage

  1. Add the script dir to your PYTHONPATH by running source jbt
  2. Debug your node process with --perf-basic-prof flag, i.e. lldb -- node --perf-basic-prof index.js
  3. Import the jbt command into lldb command script import jbt
  4. Set a breakpoint, i.e. b uv_fs_read
  5. When you hit the breakpoint type jbt to see the stack trace with JavaScript symbols resolved

Xcode

To make things work with Xcode do the following:

  1. Run jbt to determine where jbt.py was installed on your machine
  2. Add a ~/.lldbinit-xcode file which will be picked up by Xcode with the below content
command script import <path/to/jbt.py>

Now the jbt command will initialize itself and is accessible to you in the lldb console inside Xcode.
