Subject Python Union Behavior not consistent
Date Thu, 08 Dec 2011 14:07:06 GMT

I was using following schema to encode some data and found that while python
integers are written as double, which is not correct. Atleast it should
respect the order in which union is written.

A small change in io.py can fix this:

  def write_union(self, writers_schema, datum, encoder):
    A union is encoded by first writing a long value indicating
    the zero-based position within the union of the schema of its value.
    The value is then encoded per the indicated schema within the union.
    # resolve union
    index_of_schema = -1
    for i, candidate_schema in enumerate(writers_schema.schemas):
      if validate(candidate_schema, datum):
        index_of_schema = i
*        break*
    if index_of_schema < 0: raise AvroTypeException(writers_schema, datum)

Please include this, if it makes sense.
