-----------------------------------
Summary: gocql: inconsistent unmarshaling for empty/NULL UUID to
*[16]byte
Key: CASSGO-134
URL: https://issues.apache.org/jira/browse/CASSGO-134
Project: Apache Cassandra Go driver
Issue Type: Improvement
Components: Core
Reporter: Xiaonan Chen
*Problem*
Currently, when unmarshaling a UUID column from Cassandra, there is an
inconsistency between non-empty and empty/NULL values:
* Non-empty UUIDs can be successfully unmarshaled to {{*[16]byte}}
* Empty or NULL UUIDs fail to unmarshal to {{*[16]byte}}
This inconsistency causes unexpected errors when handling NULL UUID values in
the application, as the driver should handle both cases uniformly.
*Proposed Fix*
The PR modifies the unmarshaling logic to handle empty/NULL UUIDs consistently,
allowing them to be unmarshaled to {{*[16]byte}} just like non-empty UUIDs.
*Related PR*
[https://github.com/apache/cassandra-gocql-driver/pull/1967]
*Testing*
The change has been tested with both non-empty and empty/NULL UUID cases to
ensure consistent behavior.
