2019-10-31upgrade to 7.28.0.Final drools librariesjhh1-6/+8
commons-lang does not seem to be packaged anymore (commons-lang3 still does, which is the desired one). There are some @SupressWarning that seem to have no effect that were removed. Some libraries that were explicitly added are transitively used now in the latest version of drools, hence some rework in the dependency and exclude sections. We will need to generate a clm report to verify.

2019-10-17Reimplement Lock API using Lock objectsJim Hahn8-888/+358
Modified PolicyResourceLockManager to just return a feature, deferring the lock() call/method to the feature, itself. The manager was also modified so that, if it can't find an enabled provider, it will return a default provider, whose lock() methods always fail. Once a feature has been identified, the manager will cache it for use thereafter. Modified the feature API to return lock objects and simplified the interface to remove the beforeXxx and afterXxx methods. Moved the unlock and refresh methods from the feature API into the lock class, renaming them to free and extend, respectively. Added a separate, feature-simple-locking project, which implements a simple version of the locking feature, over a single JVM. Extensively revised the distributed locking feature to fit in with the new API. Added support for persistence so that the various LockImpl classes can be serialized and still function correctly when they are deserialized back into new feature instances Added default implementations of free & extend to LockImpl. Modified API to take the ownerKey string, instead of the owner object. Removed Extractor as unneeded - may add via another review, if still useful. Updates per review comments: - Updated licenses in feature-simple-locking - Added beforeCreateLock & afterCreateLock to feature API - Moved SimpleLockingFeature into policy-management so that it's always available - Moved the executor service, "exsvc", into PolicyEngine - Moved Extrator into policy-utils - Changed Extractor logging level for exceptions - Fixed feature sequence numbers - Fixed mixing of seconds and milliseconds - Renamed exsvc - Modified to use property method with default value - Configured scheduled executor - Added suffix to Extractor.register() - Eliminated Feature Api and tied lock manager into engine - Added non-null checks to LockImpl parameters - Added non-null checks to createLock() parameters - Checked that lockManager is initialized Change-Id: Iddba38157ddc5f7277656979c0e679e5489eb7b1 Issue-ID: POLICY-2113 Signed-off-by: Jim Hahn <jrh3@att.com>

This change includes feature hooks, so a "smart insert" could forward the object to a remote host, and do the insert there. The methods 'insert' and 'insertAll' in 'PolicyContainer' now make use of this smart insert.

2019-08-15Fix more sonar issues in drools-pdpJim Hahn1-18/+24
Addressed issues of cyclomatic complexity and deep nesting by refactoring code into separate methods. In some cases, had to refactor the code into nested classes to avoid passing too many parameters to the newly extracted methods. Addressed issue "too many conditionals" by breaking conditionals apart. Addressed issue "Remove usage of generic wildcard type" by eliminating "? extends" from return values. Addressed issue "Remove this use of 'Thread.sleep()'" in junit tests by introducing latches or using Awaitility. Note: this won't build until ApiUtils has been merged.

2018-07-18Deny subsequent lock()Jim Hahn2-12/+7
This is the final step of separating the lock "refresh" operation from the original "lock" operation. This step entails rejecting subsequent "lock" requests, even by the same owner, when a resource is already locked; "refresh" should now be used, instead, to extend a lock. Modified comments to indicate that the lock can only be extended using "refresh". Change-Id: I406cf60c076dbce87afbd94fb301732359dbd2db Issue-ID: POLICY-872 Signed-off-by: Jim Hahn <jrh3@att.com>
