python implementation calls seek on input, unable to read avros from a stream
-----------------------------------------------------------------------------
Key: AVRO-959
URL: https://issues.apache.org/jira/browse/AVRO-959
Project: Avro
Issue Type: Bug
Components: python
Affects Versions: 1.6.1
Reporter: Sean Jensen-Grey
The python implementation of Avro calls seek on the input file handle which
precludes it from being a stream (stdin, hadoop streaming, etc)

ack -a -i seek
src/avro/datafile.py
109: # seek to the end of the file and prepare for writing
110: writer.seek(0, 2)
190: DataFileReader.seek(long). Forces the end of the current block,
261: self.reader.seek(0, 2)
263: self.reader.seek(remember_pos)
270: # seek to the beginning of the file to get magic block
271: self.reader.seek(0, 0)
316: return True. Otherwise, seek back to where we started and return False.
320: self.reader.seek(-SYNC_SIZE, 1)
src/avro/io.py
148: reader is a Python object on which we can call read, seek, and tell.
267: self.reader.seek(self.reader.tell() + n)
src/avro/txipc.py
