pycharm - how to trace hidden class method get

Question

class Foo():
    def __init__(self):
        self.bar_ref = self.bar  # Allocation occurs here
        self.x = 0.1

    def bar(self, _):
        self.x *= 1.2

@wim said

The dotted attribute access self.bar is an invocation of descriptor __get__, creating a bound method.

How do I get Pycharm to show __get__ being executed when debugging?

Depends o what you mean by _show `__get__` being executed_ and also what is the use-case here ? — scharette, Jun 21 '18 at 18:03
I want to get a complete picture of what happens when `self.bar` is executed. — Bob, Jun 21 '18 at 18:04

The relevant __get__ method is implemented in C; it's func_descr_get in Objects/funcobject.c. PyCharm does not support stepping into code written in C.

I believe you could step into this code with a Python debug build and the Cython GDB extension, or even with a Python debug build and regular GDB if you're okay with seeing everything from the raw C-level perspective, but you can't do it in PyCharm.

Is there a way to configure Pycharm to at least inform me when it executes any C methods? – Bob Jun 21 '18 at 18:03
@Adrian: Pretty sure that's a no. PyCharm doesn't see that deep into the C. – user2357112 Jun 21 '18 at 18:05
