Log:
DERBY-1758: Enable xmlSuite to run as part of derbyall for qualified JVMs
This patch was contributed by A B (qozinx@gmail.com)
This patch adds two JUnit tests to lang/_Suite.java. The first test,
XMLTypeAndOpsTest.java, is meant to be a JUnit equivalent to the current
lang/xml_general.sql test. The second test, XMLMissingClassesTest,
tests the behavior of the SQL/XML operators when the required JAXP
or Xalan classes are not in the classpath.
The XML classes can be provided in any of a number of ways:
1) bundled into the JVM
2) installed as endorsed libraries
3) specified in the classpath
Hand-testing was performed to ensure that the new JUnit tests perform
correctly in these various configurations.
If the tests are run in an environment which does not support the XML
features, the tests quietly do nothing.
The patch, d1758_newJUnitTests_v2.patch, also adds a new utility method
and some associated state to JDBC.java for checking two things:
1) that the classpath has JAXP and Xalan classes, and
2) if the classpath has Xalan, check that the version of Xalan meets
the minimum requirement for use of Derby SQL/XML operators.
These methods/flags are then used to determine when to run the new
XML JUnit tests.
NOTE: After this patch has been reviewed/updated and finally committed
I will post a separate patch to remove the old lang/xml_general.sql test
and the corresponding master files. I will then continue addressing the
rest of the tasks for this issue (esp. xmlBinding.java) in incremental fashion.
