Problem description
Right now we have a check that warns a user that they forgot to call super().__init__()
in their overridden __init__
function. This is really useful and handles most bugs that users might accidentally make if they're not super familiar with pybind11.
However, if they don't call super().__init__
first, then other kinds of potentially undefined behavior could occur, which are also going to be difficult to diagnose from pure python. I wonder if there's a clever way that we can redirect all python method calls / attribute accesses on an object IFF that object has an __init__
to some method that tells the user to call super().__init__
first? Then after the base __init__
is called that sets the methods up to point at the correct functions?
I don't think we can add checks at any method call because the performance hit would be too high. It's possible other ways to do this would also result in performance hits.
Reproducible example code
This doesn't actually break in all cases, but I'd like this to throw an exception if possible.
from pybound_library import CppClass
class PyClass(CppClass):
def __init__(self):
self.cppMethod()
super().__init__()
