This is true for bytes, but not for bytearray. >>> bytearray(b'a')[0] 97 [28493 refs] >>> b'a'[0] 'a' And this causes error on my environment like this. ====================================================================== FAIL: testDecoder (main.StatefulIncrementalDecoderTest) ---------------------------------------------------------------------- Traceback (most recent call last): File "testio.py", line 629, in testDecoder self.assertEquals(d.decode(input, eof), output) AssertionError: u'o.i.a.b.c.d.' != u'abcd.' But strange, I cannot see this error on python.org buildbot.
The buildbots don't fail, because StatefulIncrementalDecoderTest is not listed in the run_unittest() call :-(.
I found the cause of the problem: in io.py, TextIOWrapper.tell() calls decode() with a bytearray, without any reason it seems. I will take care of this tonight, if bugs.python.org is available.
