Finding which addon an operator belongs to

Question

A recent question / answer involves what looks like an overridden operator:

bpy.ops.object.align()

Differing from the documented default, how do we find which addon(s) have registered the operator.

Method 1:

Edit to match operator id.

op_name = "import_scene.obj"

Script:

import addon_utils
from bpy.types import Operator
from importlib import import_module
import inspect
op_name = "import_scene.obj"
for m in addon_utils.modules():
    name = m.name
    default, loaded = addon_utils.check(name)
    if loaded:
        mod = import_module(name)
        classes = getattr(mod, "classes", [])
        for c in classes:
            if (
                issubclass(c, Operator) 
                and

                getattr(c, "bl_idname", "").startswith(op_name)
                ):
                print(name)
    if not classes:
        for k in dir(mod):
            cls = getattr(mod, k, None)
            if inspect.isclass(cls) and issubclass(cls, Operator):
                id = getattr(cls, "bl_idname", "")
                if id.startswith(op_name):
                    print(name)

By either looking at the addons classes or inspecting all objects of enabled addons. How do I run an existing add-on via the python API?

Method 2:

This approach disable, check op is still registered, re-enable...

Edit your operator of interest into

op_id = bpy.ops.import_scene.obj.idname()

Script:

import addon_utils
import bpy
op_id = bpy.ops.import_scene.obj.idname()
for m in addon_utils.modules():
    name = m.name
    default, loaded = addon_utils.check(name)
    if loaded:
        addon_utils.disable(name)
        if not hasattr(bpy.types, op_id):
            print(name)
            #addon_utils.enable(name)
            #break
        addon_utils.enable(name)

How would you approach finding an operators registering addon(s) from its id name?.

Note: don't save preferences after running this, as addon preferences could be lost after disable.
