Subject [jira] Updated: (DERBY-900) Remove use of String(byte[]) and String(byte[], int, int) constructors in network client leading to non-portable behaviour
Date Tue, 02 May 2006 21:11:47 GMT
     [ http://issues.apache.org/jira/browse/DERBY-900?page=all ]

Sunitha Kambhampati updated DERBY-900:

    Attachment: derby900_p2_cleanup.diff.txt

Thanks Kathey for committing my earlier p2 encoding change patch. 

It was decided earlier to break up the derby900.p2.diff.txt, so I am attaching now a patch
with the cleanup changes separately in derby900_p2_cleanup.diff.txt.  Changes are:

--  remove unnecessary conversion from sqlstate string to bytes and  back to string , in parseSQLDCGRP(Sqlca[]
rowsetSqlca, int lastRow)  in NetConnectionReply.
This has been done by adding a  constructor in NetSqlca to take in the sqlstate as string.
-- cleanup method getSqlState() in Sqlca.
-- cleanup of ccsid_ in Sqlca as it is not used.

Please note, the parseSQLDCGRP method in  the diff shows more changes because of  change in
indentation because of removal of the try block.

-- ran derbynetclientmats on ibm142/linux OK.

Can someone please look at this.  Thanks.

> These constructors use the Java default platform encoding to convert the bytes to a String,
this typically leads to bugs on platforms with different encodings.
> Replace with code using fixed conversion, or alternative mechanisms. 
> If the call is required its use should be commented as to why it is required.
