AttributeError: characters_written

[kopchik]

I've got AttributeError when exceptions are raised:

Client side:

    187                 data = data[count:]
    188         except socket.error:

[kopchik]

Yes, server side is ipython-less.

[tomerfiliba]

[kopchik]

Yes, both client and server are run by normal python. I used ipython just for the demonstration.

[oliverdrake]

For what it's worth I tried this code in my python 2.7 setup and it works fine (rpyc 3.2.3). Havn't tried py3.3 though.

[kopchik]

Could you please try on python 3.x?

[oliverdrake]

I get the same exceptions as you do when I run this on py3.3 (rpyc 3.2.3)

[tomerfiliba]

@kopchik or @oliverdrake - i pushed a small patch, could you verify if it works now?

[tomerfiliba]

(on master, not 3.2)

@tomerfiliba: now I got this:

[tomerfiliba]

btw, see http://docs.python.org/dev/library/exceptions.html (grep for
characters_written)
