Brandon Berg commented on ZOOKEEPER-2763:
-----------------------------------------
Not a reviewer, so I don't think I have a say here, but just to give my
opinion: This mostly looks good, but I'm not a huge fan of the way the '#' is
added via String concatenation. This reallocates another potentially very large
buffer and copies the whole hex string just to prepend a single hash character.
The approach I suggested in my last comment (passing a prefix in as an argument
to toHexString()) avoids the reallocation and copy by allocating space for it
in the original StringBuilder.

> Key: ZOOKEEPER-2763
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2763
> Project: ZooKeeper
> Issue Type: Bug
> Components: jute
> Affects Versions: 3.5.2
> Reporter: Brandon Berg
> Assignee: Alburt Hoffman
> Priority: Minor
>
> org.apache.jute.Utils.toCsvBuffer(), which converts a byte array to a string
> containing the hex representation of that byte array, omits the leading zero
> for any byte less than 0x10, due to its use of Integer.toHexString, which has
> the same behavior.
> https://github.com/apache/zookeeper/blob/master/src/java/main/org/apache/jute/Utils.java#L234
> One consequence of this is that the hex strings printed by
> ClientCnxn.Packet.toString(), used in the debug logging for
> ClientCnxn.readResponse(), cannot be parsed to determine the result of a
> Zookeeper request from client debug logs.
> Utils.toXmlBuffer() appears to have the same issue.
