[New-bugs-announce] [issue5391] mmap: read_byte/write_byte and object type

[Hirokazu Yamamoto]

New submission from Hirokazu Yamamoto <ocean-city at m2.ccsnet.ne.jp>:

On Python3000, mmap.read_byte returns str not bytes, and mmap.write_byte
accepts str. Is this intended behavior?

>>> import mmap
>>> m = mmap.mmap(-1, 10)
>>> type(m.read_byte())
<class 'str'>
>>> m.write_byte("a")
>>> m.write_byte(b"a")

Maybe another possibility. read_byte() returns int which represents
byte, write_byte accepts int which represents byte. (Like b"abc"[0]
returns int not 1-length bytes)
