[New-bugs-announce] [issue2298] Patch for "string without null bytes" check in getargs.c

[Douglas Greiman]

New submission from Douglas Greiman <dgreiman at users.sourceforge.net>:

Code in getargs.c:convertsimple incorrectly uses PyUnicode_GetSize
instead of PyString_GET_SIZE when checking whether a bytes object
(encoded string) contains a null byte.

To reproduce: __import__('\u0080')
Incorrect behavior:
  TypeError: __import__() argument 1 must be string without null bytes,
not str
Correct behavior: 
  ImportError

Note the lack of null bytes:
  >>> '\u0080'.encode('utf-8')
  b'\xc2\x80'
