[jira] [Commented] (DIRAPI-83) Debug logging causes never ending
loop whn decoding messages
[ https://issues.apache.org/jira/browse/DIRAPI-83?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13265506#comment-13265506 ]
Emmanuel Lecharny commented on DIRAPI-83:
-----------------------------------------
I'm not even sure why we set and reset the buffer... This is probably due to some old code that was using something else than array() to read the ByteBuffer, but as array() returns the internal byte[], there is no need for those two guys.

> Key: DIRAPI-83
> URL: https://issues.apache.org/jira/browse/DIRAPI-83
> Project: Directory Client API
> Issue Type: Bug
> Affects Versions: 1.0.0-M11
> Environment: Fedora 16 x64, Java 7, OpenLDAP 2.4.26
> Reporter: Sumit Raja
> Priority: Minor
>
> When a lookup for an entry is done with debug enabled the message decoding goes into a continuous loop till the search times out. This happens with OpenLDAP when the "ERR_00043_REMAINING_BYTES_FOR_DECODED_PDU The PDU has been fully decoded but there are still bytes in the buffer." error occurs
> I don't have a test case but a simple LdapConnection.lookup with debug logging enabled causes this.
> The fix looks pretty straightforward - the actual offending code is in org.apache.directory.shared.ldap.codec.protocol.mina.LdapProtocolDecoder.decode(). The buffer.position is set(:134) and reset(:145) without a mark being set.
> The workaround is to turn off debug logging for the "org.apache.directory" logger
