> Avro Binary Decoding - Gracefully Handle Long Strings
> -----------------------------------------------------
>
> Key: AVRO-2048
> URL: https://issues.apache.org/jira/browse/AVRO-2048
> Project: Avro
> Issue Type: Improvement
> Components: java
> Affects Versions: 1.7.7, 1.8.2
> Reporter: BELUGA BEHR
> Assignee: BELUGA BEHR
> Priority: Minor
> Attachments: AVRO-2048.1.patch
>
>
> According to the
> [specs|https://avro.apache.org/docs/1.8.2/spec.html#binary_encode_primitive]:
> bq. a string is encoded as a *long* followed by that many bytes of UTF-8
> encoded character data.
> However, that is currently not being adhered to:
> {code:title=org.apache.avro.io.BinaryDecoder}
> @Override
> public Utf8 readString(Utf8 old) throws IOException {
> int length = readInt();
> Utf8 result = (old != null ? old : new Utf8());
> result.setByteLength(length);
> if (0 != length) {
> doReadBytes(result.getBytes(), 0, length);
> }
> return result;
> }
> {code}
> The first thing the code does here is to load an *int* value, not a *long*.
> Because of the variable length nature of the size, this will mostly work.
> However, there may be edge-cases where the serializer is putting in large
> length values erroneously or nefariously. Let us gracefully detect such
> scenarios and more closely adhere to the spec.
