Arshad Mohammad commented on ZOOKEEPER-2227:
--------------------------------------------
Thanks [~cnauroth] for the patch. Here is one review comment.
To trace all the log level mask value is 1022
{code}
long ALL = CLIENT_REQUEST_TRACE_MASK | CLIENT_DATA_PACKET_TRACE_MASK
| CLIENT_PING_TRACE_MASK | SERVER_PACKET_TRACE_MASK
|
SESSION_TRACE_MASK|EVENT_DELIVERY_TRACE_MASK|SERVER_PING_TRACE_MASK|WARNING_TRACE_MASK|JMX_TRACE_MASK;
{code}
After applying your patch, when this mask is set netcat using {{echo stmk
1022|netcat host port}}, {{java.nio.BufferUnderflowException}} exception is
thrown.
This happens because " 1022" is not serialized to 8 bytes but actually 5 bytes.
So can you make it work even in this scenario by reading the number of bytes
available
> stmk four-letter word fails execution at server while reading trace mask
> argument.

> When the server handles the {{stmk}} four-letter word, it attempts to read an
> 8-byte Java {{long}} from the request as the trace mask argument. The read
> fails, because the destination buffer's capacity is only 4 bytes.
