Over the time I started to get more and more requests to have python-gammu working with Python 3. Of course this request makes sense, but I somehow failed to find time for that.
Also for quite some time python-gammu has been distributed together with Gammu sources. This was another struggle to overcome when supporting Python 3 as in many cases users will want to build the module for both Python 2 and 3 (at least most distributions will want to do so) and with current CMake based build system this did not seem to be easy to achieve.
So I've decided it's time to split python module out of the library. The reasons for having that together are no longer valid (libGammu has quite stable API these days) and having standard module which can be installed by pip is a nice thing.
Once the code has been put into separate git module, I've slowly progressed on porting to Python 3. Most of the problems were on the C side of the code, where Python really does not make it easy to support both Python 2 and 3. So the code ended up with many #ifdefs, but I see no other way. While doing these changes, many points in the API were fixed to accept unicode stings in Python 2 as well.
Anyway, today we have first successful build of python-gammu working on both Python 2 and 3. I'm afraid there is still some bug leading to occasional segfaults on Travis, but not reproducible locally. But hopefully this will be fixed in upcoming weeks and we can release separate python-gammu module again.
