Subject [jira] [Updated] (DERBY-6213) Deprecate support for Java 5 and CDC
Date Thu, 22 Aug 2013 12:23:53 GMT

     [ https://issues.apache.org/jira/browse/DERBY-6213?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Knut Anders Hatlen updated DERBY-6213:
--------------------------------------

    Attachment: decimal-type.diff

There's still some code to support different implementations of the DECIMAL data type depending
on whether the BigDecimal class is available. There is only one implementation of the DECIMAL
data type now, so we can remove the existing logic for plugging in the correct implementation.

The attached decimal-type.diff patch makes the following changes:

- Stop using reflection to access the BigDecimal class.

- Fold J2SEDataValueFactory into DataValueFactoryImpl.

- Make the parser represent DECIMAL literals as BigDecimal instead of String.

- Remove (now unused) DataValueFactory methods that manipulate strings representing DECIMAL
values.

- Clean up some comments that mention CDC support.

All regression tests ran cleanly.

> The developer community has approved the proposal to sunset support for Java 5 and CDC:
http://apache-database.10148.n7.nabble.com/VOTE-Sunsetting-support-for-Java-5-and-CDC-td129832.html#a129925
> This issue tracks a number of tasks needed to implement this proposal:
> I) Remove build support for Java 5 and CDC.
> II) Purge user doc references to Java 5, CDC, and the JDBC 4 DataSources.
> III) Remove the JDBC 4 version of the public api from the published javadoc. The recently
introduced CP2 DataSources would need to migrate to the JDBC 3 version of the published javadoc.
The JDBC 4 versions of the DataSources would still exist, but they would be vacuous extensions
of their JDBC 3 counterparts.
> IV) On the wiki, document our expectation that maintenance releases will support the
same platforms as the original feature release cut from their branch.
> V) Decide what to do with the SimpleMobileApp. Probably we want to just remove this demo
since its purpose is to show how to run Derby on the deprecated CDC platform.
