Michael A. Smith created AVRO-2183:
--------------------------------------
Summary: Nameless schema should raise AttributeError when
attempting to access name
Key: AVRO-2183
URL: https://issues.apache.org/jira/browse/AVRO-2183
Project: Avro
Issue Type: Bug
Components: python
Reporter: Michael A. Smith
In the "py" implementation, this works as expected:
{noformat}
>>> from avro.schema import parse
>>> s = parse('{"type": "array", "items": "int"}')
>>> s.name
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'ArraySchema' object has no attribute 'name'{noformat}
but in the py3 implementation, a {{NameError}} is raised instead:
{noformat}
>>> from avro.schema import Parse
>>> s=Parse('{"type":"array","items":"int"}')
>>> s.name
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/michaels/dev/avro/lang/py3/avro/schema.py", line 224, in name
return self._props['name']
KeyError: 'name'{noformat}
This behavior breaks several python idioms, including the ability to get a
default value using {{getattr}}:
{noformat}
>>> getattr(s, "name", "default")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/michaels/dev/avro/lang/py3/avro/schema.py", line 224, in name
return self._props['name']
KeyError: 'name'{noformat}
I will open a PR with tests and a fix.
