# If you use the GNU debugger gdb to debug the Python C runtime, you
# might find some of the following commands useful. Copy this to your
# ~/.gdbinit file and it'll get loaded into gdb automatically when you
# start it up. Then, at the gdb prompt you can do things like:
#
# (gdb) pyo apyobjectptr
# <module 'foobar' (built-in)>
# refcounts: 1
# address : 84a7a2c
# $1 = void
# (gdb)
# Prints a representation of the object to stderr, along with the
# number of reference counts it current has and the hex address the
# object is allocated at. The argument must be a PyObject*
define pyo
print _PyObject_Dump($arg0)
end
# Prints a representation of the object to stderr, along with the
# number of reference counts it current has and the hex address the
# object is allocated at. The argument must be a PyGC_Head*
define pyg
print _PyGC_Dump($arg0)
end
# If you are in an eval_frame() function, calling pyframe with no
# arguments will print the filename, function name, and line number.
# It assumes that f is the name of the current frame.
define pyframe
x/s ((PyStringObject*)f->f_code->co_filename)->ob_sval
x/s ((PyStringObject*)f->f_code->co_name)->ob_sval
p f->f_lineno
