Investigate tuple encoding bug #12

Closed crclark closed 5 years ago

crclark commented 5 years ago

Our implementation used the Python implementation of the tuple layer as a reference to check encoding correctness.

2 ^ 64 - 1 is encoded in our implementation and in Python as "\x1d\x08\xff\xff\xff\xff\xff\xff\xff\xff" when it should be encoded as "\x1c\xff\xff\xff\xff\xff\xff\xff\xff". Its predecessor is correctly encoded as "\x1c\xff\xff\xff\xff\xff\xff\xff\xfe".
