Mamta A. Satoor updated DERBY-4786:
-----------------------------------
Attachment: DERBY4786_patch1_diff.txt
Attaching a patch to fix the jira. What the patch does is it checks if the
optional username and password have specified for the shutdown command and if
yes, then it uses protocol level 2 and then sends the username and password
info to the server when sending the shutdown command. If user has not specified
username and password then it uses protocol level 1 and sends just the shutdown
command the way it used to work prior to DERBY-2109. In other words, protocol
level 1 for shutdown with no username and password and protocol level 2 for
shutdown with username and password.
Server on its side checks if it is dealing with protocol level 1 for shutdown
and if yes, then it does not need to look for username and password. But if the
the protocol level is 2, then the server will expect username and password for
the shutdown command,
This way, a trunk client with this patch will be able to shutdown a 10.3 server
with DERBY-2109 changes with no username and password. If it sends the username
and password then there be following error on the server and client side
10.3 server side error
DRDA_UnknownProtocol.S, <2>
Execution failed because of a Distributed Protocol Error:
DRDA_Proto_SYNTAXRM;CODPNT arg = 0; Error Code Value = 1. Plaintext connection
attempt from an SSL enabled client?
trunk client side error
Tue Aug 31 11:48:20 PDT 2010 : Invalid reply header from network
server: Invalid string. Plaintext connection attempt to an SSL enabled server?
Please let me know if anyone has any feedback on this patch. I will plan on
committing this in a day or two.
> Shutdown command without username and password should work with mixed client
> and network server releases.

> Project: Derby
> Issue Type: Bug
> Components: Network Client, Network Server
> Affects Versions: 10.4.1.3, 10.4.2.0, 10.5.1.1, 10.6.1.0

> DERBY-2109 introduced optional parameters username and password to the
> shutdown command. But with this fix, the existing shutdown command which does
> not use username and password stopped working from client with DERBY-2109
> changes against a network server without DERBY-2109 changes.
> This jira is to ensure that existing shutdown command without user name and
> password still works fine between different releases of client and network
> server(with or without DERBY-2109). The new shutdown command introduced by
> DERBY-2109 will work obviosuly only on client and server with DERBY-2109
> changes. For client/server not with DERBY-2109 changes attempting to user use
> name and password will get an error.
