diff Objects/stringobject.c @ 24736:ff05eef3a6d1 legacy-trunk
Implement stage B0 of PEP 237: add warnings for operations that
currently return inconsistent results for ints and longs; in
particular: hex/oct/%u/%o/%x/%X of negative short ints, and x<<n that
either loses bits or changes sign. (No warnings for repr() of a long,
though that will also change to lose the trailing 'L' eventually.)
This introduces some warnings in the test suite; I'll take care of
those later.
