Thanks for the offer!
Do we need to do forward and reverse in python? Reverse back to 369
(Vincent's earlier patch for 2.0 svn) is easy - just convert the author IDs
from an integer hash value to a sequence (1,2,3). I think they can just be
in order of occurrence.
Forward would be a bit trickier if we had to calculate the hash function
value in python as well. There's an example here for a different hash
function:
http://stackoverflow.com/questions/793761/built-in-python-hash-function
But this does remind me that we need to double check there are no problems
with a) string encoding or b) endianness. The hash function obviously needs
to return the same value on every platform if the author name/email are the
same.
Best,
Greg.
