Tyler Harwood created AVRO-4173:
-----------------------------------
Summary: [JavaScript] Incorrect type resolution in nested schemas
Key: AVRO-4173
URL: https://issues.apache.org/jira/browse/AVRO-4173
Project: Apache Avro
Issue Type: Bug
Components: js
Reporter: Tyler Harwood
Namespace inheritance is broken when parsing nested record types with mixed
explicit and inherited namespaces. This causes type resolution to fail with
"undefined type name" errors.
Example code to reproduce the bug:
{code:java}
const avro = require('avro-js');
const schema = {
type: 'record',
name: 'Parent',
namespace: 'parent.ns',
fields: [
{
name: 'child_field',
type: {
type: 'record',
name: 'Child', // No namespace - should inherit 'parent.ns'
fields: [{name: 'value', type: 'int'}]
}
},
{
name: 'other_field',
type: {
type: 'record',
name: 'Other',
namespace: 'different.ns', // Explicit namespace corrupts context
fields: [{name: 'data', type: 'int'}]
}
},
{
name: 'reference_field',
type: 'Child' // References Child - should resolve to 'parent.ns.Child'
}
]
};
// This fails with "undefined type name: different.ns.Child"
const type = avro.parse(schema);
{code}
