I will freely admit that I haven't followed this thread in any detail, but if it were up to me, I'd have the 2.6 internal code use PyString (as both what the linker sees and what the human reads in the source code) and the 3.0 code use PyBytes for the same thing. Let the merges be damed -- most changes to 2.6 these days seem to be blocked explicitly from being merged anyway. I'd prefer the 2.6 code base to stay true to 2.x, and the 3.0 code base start afresh where it makes sense. We should reindent more of the 3.0 code base to use 4-space-indents in C code too.

I would also add macros that map the PyBytes* APIs to PyString*, but I would not start using these internally except in code newly written for 2.6 and intended to be "in the spirit of 3.0". IOW use PyString for 8-bit strings containing text, and PyBytes for 8-bit strings containing binary data. For 8-bit strings that could contain either text or data, I'd use PyString, in the spirit of 2.x.

Let's work on better merge tools that edit the trunk code base into shape for a 3.x checkin.

Using automated tools for this is likely going to lower the probability of bugs introduced due to unnoticed merge conflicts and in the end is also going to be a benefit to everyone wanting to maintain a single code base for both targets.

Perhaps we could revive the old Tools/scripts/fixcid.py that was used for the 1.4->1.5 renaming ?!
