Antoine Pitrou updated ARROW-1450: ---------------------------------- Component/s: Python > [Python] Raise proper error if custom serialization handler fails > ----------------------------------------------------------------- > > Key: ARROW-1450 > URL: https://issues.apache.org/jira/browse/ARROW-1450 > Project: Apache Arrow > Issue Type: Bug > Components: Python > Reporter: Philipp Moritz > Assignee: Philipp Moritz > Priority: Major > Fix For: 0.7.0 > > > At the moment, the following fails: > {code:none} > def test_serializaton_callback_error(): > class TempClass(object): > pass > # Have a SerializationContext but TempClass is not > # registered > serialization_context = pa.SerializationContext() > with pytest.raises(pa.SerializationCallbackError): > serialized_object = pa.serialize(TempClass, serialization_context) > {code} > This is because serialize will raise a generic ArrowException instead of a > SerializationCallbackError. We do need the latter because it contains the > object that couldn't be serialized, which is important to give good error > messages; in the case of Ray we sometimes want use the object to register > additional serialization callbacks on the fly to make the user experience > smoother. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
