Subject [jira] [Updated] (DERBY-5488) Add remaining JDBC 4.1 bits which did not appear in the Java 7 javadoc.
Date Fri, 04 Nov 2011 19:49:52 GMT

Rick Hillegas updated DERBY-5488:

    Attachment: z.java

Attaching derby-5488-04-aa-fixBigIntegerDecimal.diff. This patch is not ready for commit yet
because there is still a problem in ParameterMappingTest on CDC/FP 1.1.

This patch gets rid of the NPE. It does this by moving some logic out of the data factory
into SQLDecimal and by implementing some more methods in the small device version of SQLDecimal,
which is called BigIntegerDecimal. I don't think this is the correct long term fix. The correct
long term fix is for our small device implementation to use SQLDecimal and to get rid of BigIntegerDecimal.
This ought to be possible because java.math.BigDecimal is in CDC/FP 1.1 (it wasn't in the
earlier version of CDC/FP on which our small device implementation was based originally).
However, I think that there may be some deserialization and upgrade issues for legacy databases
which have stored BigIntegerDecimals. Fixing those issues seems to me to be the province of
another JIRA.

After clearing away the current problems with ParameterMappingTest, the test trundles along
and hits a new problem: a failure on small devices to resolve a procedure which has BINARY
argument types. I have attached a program, z.java, which shows this problem. The program runs
fine on JDK 6 but fails on OJEC.

I will attach a functional spec for the remaining bits.
