JingWei Li updated FLINK-35529:
-------------------------------
Description:
The main bug occurs during the decode process. The decode method is a method
generated by the codegen of Flink at runtime, and in the process of generating
the decode method, some getter and setter methods of the protobuf object need
to be used to construct the RowData. Currently, the way to generate the getter
and setter is through string concatenation, using the "get" prefix and
camelCase variable names. Some special characters may lead to errors in the
generated Getter and Setter methods, thus causing bugs.
- Examples:
- If the protobuf defines a field named "class", the Getter method will be
getClass(), which conflicts with the Object.getClass() method, so the real
value of the "class" field cannot be accessed. The method generated by protoc
is getClass_().
- If the protobuf defines two fields "a_b_c" and "ab_c", the Getter methods
are both getABC(), causing a naming conflict. The methods generated by protoc
are getABC+sequence number().
