[ http://issues.apache.org/jira/browse/DERBY-1075?page=all ]
David Van Couvering updated DERBY-1075:
---------------------------------------
Attachment: classloader.jar
Hi, Deepa. This is a copy of engine/org/apache/derby/jdbc in my sandbox.
DerbyLoader.jar is a classloader I wrote to handle code sharing. You will
notice that there are two things going on:
- A number of the classes have been split up into a "proxy" and its underlying
implementation that it delegates to
- The underlying implementation implements an interface defined in the
"interfaces" package. The interfaces need to be a separate package to avoid
sealing issues
- The proxy class loads the implementation class using DerbyLoader and then
casts it to the appropriate interface, and then invokes methods via that
interface.
Let me know if you have any questions. It's been a while since I worked on
this but I think I can get the cogs working again if need be.
I have granted license for this in case Deepa wants to use some or all of this
code herself, but in general it is *not* intended for checkin as is.

> Separating a part of DERBY-514 into a sub-task. This sub-task is to combine
> the script 'runphases.ksh' and the java file 'phaseTester.java' into a single
> java test. This will help to later add the upgrade tests into the regression
> suite. Also, this sub-task can be done independent of DERBY-1049 which is
> blocking DERBY-514.
