V.Narayanan updated DERBY-2604:
-------------------------------
Attachment: ClobLocatorWork_v4.stat
ConnectionLocatorWork_v4.diff
This patch addresses the bugs that were found during the process of enabling
Clob support for locators.
Pls note that Clob locators are currently disabled.
I have not yet run junit All for the patch. Since the code is diabled I do not
expect any failures. But I will run junit All and revert back with the results.
The following are the details of the details of the files modified and their
import apropos the context.
M java/client/org/apache/derby/client/am/ClobLocatorWriter.java
writeCharacters(line no 162) method was using c.length as the length of the
string
transmitted to the server using the clobSetString stored procedure. This should
use len instead.
M java/client/org/apache/derby/client/am/Clob.java
The PositionX method on the client that accepts a Clob had not been converted
to use locators. This has been done.
The getCharacterStream(long pos, long length) method should return a stream of
length characters starting from pos. Hence the length parameter that should be
passed to the constructor of the ClobLocatorReader class should have been
pos+len-1 instead of len.
M java/client/org/apache/derby/client/am/CallableLocatorProcedures.java
The stored procedure call to CLOBGETPOSITIONFROMSTRING was sending the
original string instead of sending it in chunks. This has been changed to send
the
chunks instead(stringToBeCompared).
