The previous implementation had the following bugs:
- DST was truncated to end of October
- DST start was off by one week in years where March 1st is a Monday
- DST start was off by one second (1:59:59 -> 2:00:00 -> 3:00:01 instead of the correct 1:59:59 -> 3:00:00 -> 3:00:01)
Tested against tzdata 2009g.
_PyTuple_Resize may destroy the original tuple and return a new one through the pointer argument. When it does that and we don?t put the new one back into the map, we end up with a stale pointer to a destroyed object in the map, which is likely to blow up one way or another next time it?s accessed.
Untested because, as far as I can see, this code isn?t actually used currently. All uses of this method deal with fixed-size SDL variables. Resizable variables are not used at all in age SDL, only in non-age SDL (animation, avatar, clothing etc.), and I?m not even sure if those are even accessible using this Python API.
Fixes egg room private chat channels and entering Teledahn buckets with Python 2.7. These and other uses of ptSDL.setIndex() only worked by chance with Python 2.3 because the tuples happened to have reference counts of 1.
