Import Error (ConfigParser) on Python 3.4.3 OS X 10.10.4

Note The ConfigParser module has been renamed to configparser in Python 3. The 2to3 tool will automatically adapt imports when converting your sources to Python 3.

I guess ConfigParser is used hard in __init__.py

It is. For me it looks like the code was developed for 2.7 and not fully tested for python 3, although python 3.4 compatibility is advertised.

In the meantime I pulled the current version 0.3.0 from git and ran setup.py, resulting in various syntax errors (see below):

Hi everyone,

it is true - although the code is announced as being 3.4 ready, the latest version(s) are actually not, simply because we had a lot of pressure to provide functionality for 2.7 without being able to make it compliant for 3.4 (again). This is definitely an issue and should be addressed but it is not clear (to me) how quickly this can be achieved.
@bsrdjan, @jarus : Should we remove the 3.4 compatibility flag for the moment until this issue is fixed?

[Balauue]

Hi,

thanks for clarification. I really hope for a quick 3.4 compliance. For you experts it is probably not even big effort as you know your code.

I tried using 2to3 tool and manually migrating obvious problems. Now I can include the library but a single SELECT query already yields exceptions:

  File "[...]/pyhdb/protocol/segments.py", line 150, in unpack_from
    raise error.parts[0].errors[0]
pyhdb.exceptions.DatabaseError: error while parsing protocol
