The test suite breaks on the Lib/test/test_uuid.py, as of r65661. This
is because uuid3 and uuid5 now raise exceptions.
TypeError: new() argument 1 must be bytes or read-only buffer, not bytearray
The problem is due to the changes in the way "s#" now expects a
read-only buffer in PyArg_ParseTupleAndKeywords. (Which was changed in
r65661).
A rundown of the problem:
Lib/uuid.py:553 (in uuid.uuid3):
 hash = md5(namespace.bytes + bytes(name, "utf-8")).digest()
namespace.bytes is a bytearray, so the argument to md5 is a bytearray.
Modules/md5module.c:517 (in _md5.md5.new):
 if (!PyArg_ParseTupleAndKeywords(args, kwdict, "|s#:new", kwlist,
Using s# now requires a read-only buffer, so this raises a TypeError.
The same goes for uuid5 (which calls _sha1.sha1, and has exactly the
same problem).
The commit log for r65561 suggests changing some s# into s* (which
allows readable buffers). I don't understand the ramifications here
(some problem with threading), and when I made that change, it seg
faulted, so I'll leave well enough alone. But for someone who knows more
what they're doing, that may be a more "root-of-the-problem" fix.
In the meantime, I propose this simple patch to fix uuid: I think
namespace.bytes should actually return a bytes, not a bytearray, so I'm
modifying it to return a bytes.

Patch for r65675.
Commit log:
Fixed TypeError raised by uuid.uuid3 and uuid.uuid5, by passing a
bytearray to hash functions. Now namespace.bytes returns a bytes instead
of a bytearray.
