DBG

What is DBG?

DBG is a Go debugger, written primarily in Go. It really needs a new name.

Building

Currently, DBG requires 2 patches to be applied to Go source to build.

  1. Dwarf Fix
  2. Process.Wait() fix.

Features

  • Attach to (trace) a running process
  • Set breakpoints
  • Single step through a process
  • Next through a process (step over / out of subroutines)
  • Never retype commands, empty line defaults to previous command

Usage

  • break - Set break point at the entry point of a function, or at a specific file/line. Example: break foo.go:13.

  • step - Single step through program.

  • next - Step over to next source line.

Upcoming features

  • Handle Gos multithreaded nature better (follow goroutine accross thread contexts)
  • In-scope variable evaluation
  • In-scope variable setting
  • Readline integration
  • Ability to launch debugging session from debugged program, with breakpoint set correctly
  • Support for OS X
