Tutorial 6: Debug the Code - ci-group/revolve GitHub Wiki

Debug the Python code

1. Run ./revolve.py

2. Run your manager script through pdb by using pdb manager.py or python -m pdb myscript.py: There are a few commands you can then issue, which are documented on the pdb page.

   Some useful ones to remember are:

   • b: set a breakpoint
   • c: continue debugging until you hit a breakpoint
   • s: step through the code
   • n: to go to next line of code
   • l: list source code for the current file (default: 11 lines including the line being executed)
   • u: navigate up a stack frame
   • d: navigate down a stack frame
   • p: to print the value of an expression in the current context

   If you don't want to use a command line debugger, some IDEs like PyDev have a GUI debugger.

Debug the C++ plugin code

1. Run gzserver with a debugger

2. Run your manager script
