Matthew Hayes commented on AVRO-1741:
-------------------------------------
Result of "mvn test" below. It's not clear to me if this exercises the Python
code. But, I tested it separately and it fixed my problem.

> Python 3 code should check if avro.codec is None before decoding

> I'm getting the error below when trying to read an Avro file in Python 3.
> FWIW, I generated this Avro file from Pig. I don't know if that makes a
> difference.
> {code}
> avro.datafile.DataFileReader(open("test.avro","rb"),avro.io.DatumReader())
> Traceback (most recent call last):
> File "<stdin>", line 1, in <module>
> File
> "/Users/mhayes/.pyenv/versions/3.4.2/lib/python3.4/site-packages/avro/datafile.py",
> line 352, in __init__
> self.codec = self.GetMeta('avro.codec').decode('utf-8')
> AttributeError: 'NoneType' object has no attribute 'decode'
> {code}
> It appears the problem is in the following code. It should check if GetMeta
> returns None before trying to decode it. The Python 2 code doesn't have this
> problem because it is already decoded.
> {code}
> # ensure codec is valid
> self.codec = self.GetMeta('avro.codec').decode('utf-8')
> if self.codec is None:
> self.codec = "null"
> if self.codec not in VALID_CODECS:
> raise DataFileException('Unknown codec: %s.' % self.codec)
> {code}
