New submission from Serhiy Storchaka:
On 3.2 subprocess.Popen.communicate with universal_newlines=True accepts bytes
and doesn't accept strings.
$ ./python -c "import subprocess; subprocess.Popen(['cat'],
stdin=subprocess.PIPE, stdout=subprocess.PIPE,
universal_newlines=True).communicate('qwerty')"
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/home/serhiy/py/cpython3.2/Lib/subprocess.py", line 833, in communicate
return self._communicate(input)
File "/home/serhiy/py/cpython3.2/Lib/subprocess.py", line 1470, in
_communicate
stdout, stderr = self._communicate_with_poll(input)
File "/home/serhiy/py/cpython3.2/Lib/subprocess.py", line 1537, in
_communicate_with_poll
input_offset += os.write(fd, chunk)
TypeError: 'str' does not support the buffer interface
On 3.3+ it accepts strings and doesn't accept bytes.
