Reza Taroosheh reassigned CASSANDRA-21763:
------------------------------------------
Assignee: Reza Taroosheh
> Responses with a string between 32768 and 65535 bytes fail, e.g. a long
> client warning
> --------------------------------------------------------------------------------------
>
> Key: CASSANDRA-21763
> URL: https://issues.apache.org/jira/browse/CASSANDRA-21763
> Project: Apache Cassandra
> Issue Type: Bug
> Reporter: Nadav Har'El
> Assignee: Reza Taroosheh
> Priority: Normal
>
> Since CASSANDRA-20234, {{CBUtil.writeString()}} on the cassandra-6.0 branch
> and trunk rejects any string longer than {{Short.MAX_VALUE}} (32767 bytes):
> {code:java}
> Preconditions.checkArgument(length <= Short.MAX_VALUE, ... "String too large;
> expected %d <= %d" ...);
> {code}
> But the native protocol's [string] has an unsigned 2-byte length, so it may
> be up to 65535 bytes, and {{ClientWarn}} still truncates warnings to
> {{FBUtilities.MAX_UNSIGNED_SHORT}} (65535). So a warning between 32768 and
> 65535 bytes makes the response fail with:
> {noformat}
> java.lang.IllegalArgumentException: String too large; expected 65535 <= 32767
> {noformat}
> and the client never gets a response, and times out. For example, a batch
> over the batch_size_warn_threshold that writes to a few hundred tables with
> long names gets such a warning, because the warning lists every table.
> Reproduced on Cassandra 6.0-alpha2. Cassandra 5.0.9 handles the same request
> correctly (its {{writeString()}} has no such check), returning the warning
> truncated, ending with " [truncated]".
> Either {{writeString()}} should allow up to 65535 bytes, or {{ClientWarn}}
> (and other callers) must truncate to 32767.
