Of particular interest to bsddb is the pep3118 buffer API. I updated the existing bsddb module found in the py3k branch to use it last fall; you may want to use the changes made to it as an example.
I agree, a single C code base is the only sane way forward for bsddb. The interesting part is that you also want to support older python versions (2.3-2.5?) as well so _bsddb.c & bsddb.h become a nice example of how to write code that spans multiple python versions.
I expect it is less difficult than it sounds.

I believe the buffer api is supposed to be backported to 2.6? I haven't followed the status of that. If so, bsddb should use it in 2.6 as well.

I can't find any PEP about detailed 2.6 -> 3000 migration guidelines, specially in the module (C code) extension area. Yes, I know about the 2to3 tool, but I'm interested in updating my 2.x code in order to keep (automatic via "2to3") difference between 2.x and 3.x codebase so small as possible. Also, 2to3 doesn't manage migration for C modules. Since I need to port bsddb3 to py3k, what I need to know?. Is any updated document out there?. PS: My plan is keep working in the python side under 2.x, and manage Python 3.0 via "2to3", for a long time. In the C side, I plan keeping the same codebase, with conditional compilation.
