Note a curious extension to the std C rules: x, X and o formatting can never produce a sign character in C, so the '+' and ' ' flags are meaningless for them. But unbounded ints *can* produce a sign character under these conversions (no fixed- width bitstring is wide enough to hold all negative values in 2's-comp form). So these flags become meaningful in Python when formatting a Python long which is too big to fit in a C long. This required shuffling around existing code, which hacked x and X conversions to death when both the '#' and '0' flags were specified: the hacks weren't strong enough to deal with the simultaneous possibility of the ' ' or '+' flags too, since signs were always meaningless before for x and X conversions. Isomorphic shuffling was required in unicodeobject.c. Also added dozens of non-trivial new unbounded-int test cases to test_format.py. |
