79b97ee2ab Fix out of bounds read in long_new() for empty bytes with an explicit base. int(b'', somebase) calls PyLong_FromString() with char* of length 1 but the function accesses the first argument at offset 1. CID 715359 2012-09-12 15:31:43 +02:00

942af5a9a4 Issue #10557: Fixed error messages from float() and other numeric 
types.  Added a new API function, PyUnicode_TransformDecimalToASCII(),

  Refactor some longobject internals:  PyLong_AsDouble and _PyLong_AsScaledDouble
  (the latter renamed to _PyLong_Frexp) now use the same core code.  The
  exponent produced by _PyLong_Frexp now has type Py_ssize_t instead of the
  previously used int, and no longer needs scaling by PyLong_SHIFT.  This
  frees the math module from having to know anything about the PyLong
  implementation.  This closes issue #5576.

  Style/consistency/nano-optimization nit:  replace occurrences of
    (high_bits << PyLong_SHIFT) + low_bits with
    (high_bits << PyLong_SHIFT) | low_bits
  in Objects/longobject.c.  Motivation:
   - shouldn't unnecessarily mix bit ops with arithmetic ops (style)
   - this pattern should be spelt the same way thoughout (consistency)
   - it's very very very slightly faster: no need to worry about
     carries to the high digit (nano-optimization).
