Subject [jira] Updated: (DERBY-683) Use correct encoding for ClobOutputStream on client
Date Tue, 16 May 2006 15:43:07 GMT
     [ http://issues.apache.org/jira/browse/DERBY-683?page=all ]

Deepa Remesh updated DERBY-683:

    Fix Version:
     Derby Info: [Patch Available]

To merge this fix, I have also ported the fix for DERBY-463 which is in the same area. The
patch for DERBY-463 is attached to http://issues.apache.org/jira/browse/DERBY-463. This patch
has to be applied before running the following merge command:

svn merge -r 374468:374469 https://svn.apache.org/repos/asf/db/derby/code/trunk

With the patch for DERBY-463 and the merge for DERBY-683, I verified that the attached repro
passes with UTF-16 file encoding in v10.1. I also ran derbynetclientmats with Sun jdk 1.4.2
on Windows XP. Please take a look at these. Thanks.

> In client, there is code in ClobOutputStream which uses this api - new String(byte[]).
  Per the java api http://java.sun.com/j2se/1.4.2/docs/api/java/lang/String.html#String(byte[])
,this will construct a string by decoding the array of bytes using the platform's default
character set. 
> org.apache.derby.client.am.ClobOutputStream is used for Clob.setAsciiStream and the write
methods  use the String(byte[]) which is incorrect because it will use the default platform
encoding. Per the jdbcapi , this should use ascii encoding. 
> In areas related to Clobs, also check for other places where  String(byte[]) is used,as
it may not be the desired behavior. 
> Dan pointed this problem here : http://issues.apache.org/jira/browse/DERBY-463?page=comments#action_12356742
