[issue29858] inspect.signature includes bound argument for wrappers around decorated bound methods

2017-03-20 Thread anton-ryzhov 

New submission from anton-ryzhov:

If we wrap function with bound method, which is also a wrapper around function, 
`inspect.signature` will not do `skip_bound_arg`.
It will use `inspect.unwrap` and pass by bound method from outer function to 
inner one.

Reproduce:
```
import functools, inspect


def decorator(func):
@functools.wraps(func)
def inner(*args):
return func(*args)
return inner


class Foo(object):
@decorator
def bar(self, testarg):
pass


f = Foo()
baz = decorator(f.bar)
assert inspect.signature(baz) == inspect.signature(f.bar)
```

[issue26724] Serialize dict with non-string keys to JSON — unexpected result

2016-04-09 Thread anton-ryzhov 

New submission from anton-ryzhov:

JSON doesn't allow to have non-sting keys in objects, so json.dumps converts 
its to string. But if several keys has one string representation — we'll get 
damaged result as follows:

>>> import json
>>> json.dumps({1: 2, "1": "2"})
'{"1": 2, "1": "2"}'

I think it should raise ValueError in this case.

I've tested this case on 2.7, 3.4 and on trunk version 3.6.
