V.Narayanan commented on DERBY-2702:
------------------------------------
I integrated this patch with all the dependent patches and ran junit All. There
were no failures in the
test run.
The following is a small description of the step-by-step procedure adopted
during the
integration process. I applied the below on a fresh workspace.
1) DERBY-2496 Enabling Blob support for locators is committed.
So I did not have to apply any patch for this dependency.
2) DERBY-2694 org.apache.derby.impl.drda.DDMWriter uses wrong algorithm to
avoid
spliting varchar in the middle of a multibyte char.
Applied the patch attached to this issue (derby-2694.diff)
3) DERBY-2587 Connection.createClob() and Connection.createBlob() need to
return
locator support enabled LOB objects in the
NetworkClient
Part of the patch related to modifying createBlob() to return locator support
enabled Blobs is already committed.
I applied ConnectionLocatorWork_v4.diff to the workspace.
In addition to applying this patch I had to do one more thing. The
createClob()
method modified in this patch has been temporarily disabled from sending
locator enabled Clobs.I had to remove the (&& false) intentional disabling
that was done.
I am hoping that I can submit a intermediate patch to remove (&& false)
between the commit of v4 attached to this issue and 2702 being committed.
4) DERBY-2604 Implement Clob support for Locators
A patch was attached to this issue addressing some bugs found in the
implementation.
Applied ClobLocatorWork_v5.diff to the workspace.
5) DERBY-2702 Enable Clob locator support between NetworkServer and
NetworkClient and modify tests that
experience changed behaviour due to this(enabling
Clob Locators).
Applied ClobLocatorWorkTestModifications.diff
6) I then did a
ant Clobber && ant all && ant buildjarsclean
on the above workspace.
7) The jars obtained from the above build was then used to run junit All.
I had a clean run. No failures were observed.
Pls find the integrated patches attached here for further reference.
Pls note that the integrated patches are *not for commit*.
