---------------------------------
Summary: Python: schemas retrieved from protocol types ignore
namespace
Key: AVRO-1296
URL: https://issues.apache.org/jira/browse/AVRO-1296
Project: Avro
Issue Type: Bug
Components: python
Affects Versions: 1.7.4
Reporter: Jeremy Kahn
Assignee: Jeremy Kahn
Fix For: 1.7.5
If I parse a protocol {{p}} using {{avro.protocol.parse}}, which defines
{{"namespace": "ns"}} and then retrieve a child schema {{s}} from the
protocol's {{proto.types}} (or {{proto.types_dict}}), then {{s}} does not have
its namespace set (to {{ns}}), even if {{p}} has a namespace.
This is particularly problematic if I'm using {{s}} to write out an avro file
intended to be read by a specific-type reader, because the file header will
claim to be objects of type {{s}} (not {{ns.s}}, as expected).
I've attached two patches: one that makes sure that the {{namespace}} property
of protocol types is set to the default namespace of the protocol when not
otherwise set.
The second patch ensures that the {{namespace}} is *not* rendered into JSON
when a default protocol specifies the right value already.
