[New-bugs-announce] [issue35108] inspect.getmembers passes exceptions from object's properties through

[Roman Inflianskas]

New submission from Roman Inflianskas <infroma at gmail.com>:

I use inspect.getmembers for getting members of splinter.webdriver.BaseWebDriver. The problem is that it has a property status_code raises NotImplementedError: https://github.com/cobrateam/splinter/blob/master/splinter/driver/webdriver/__init__.py#L191. This exception passes through try block in https://github.com/python/cpython/blob/master/Lib/inspect.py#L343 because it doesn't contain:
except Exception:
    pass
section.
In the result, instead of members of the object, I get an exception.

I think there are two possible expected behaviors:
1. Just ignore the exceptions and return members without the members, that raise exceptions.
2. Instead of members, return tuple like:
...
try:
    ...
except Exception as e:
    RAISES_EXCEPTION = object()
    value = (RAISES_EXCEPTION, e)
...
