Extend SecurityManagerSetup to add extra privileges to the set of default
privileges (merge two policy files)
-------------------------------------------------------------------------------------------------------------
Key: DERBY-5631
URL: https://issues.apache.org/jira/browse/DERBY-5631
Project: Derby
Issue Type: Improvement
Components: Test
Affects Versions: 10.9.0.0
Reporter: Kristian Waagan
Assignee: Kristian Waagan
When moving ProtocolTest into suites all (see DERBY-2031), I needed to allow
the test code to create a socket. There was already a policy file for the old
harness for doing this, but when using this with the JUnit framework I ended up
adding privilege after privilege to get the framework itself running.
Instead of creating a large policy file duplicating all the privileges that the
framework requires to function properly, I think it would be better to make the
SecurityManagerSetup capable of merging the test specific policy file with the
default policy file.
This mode of operation can be used when you need a few extra privileges to
execute the test, but there are probably also tests where you want full control
of the privileges - in which case you use the existing mode of operation.
I'm not 100% sure this approach will always work, but basic testing has shown
promising results.
