2019-10-24Handle DB error codes in distributed lockingJim Hahn6-74/+30
The commons library wraps the SQLExceptions within its own SQLException, so changed the code to simply look for a cause that's SQLTransientException, eliminating the need to check specific error codes. Deleted the error code property now that it is no longer needed. Also updated the distributed locking properties to include examples.

2019-10-17Reimplement Lock API using Lock objectsJim Hahn15-1060/+2998
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>

2018-07-18Deny subsequent lock()Jim Hahn2-4/+9
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>
2018-07-16Distinguish lock from refreshJim Hahn3-0/+75
This is the first step of separating the lock "refresh" operation from the original "lock" operation. This step entails adding the refresh() method to both the default and the feature-distriubted locking mechanisms. Change method call, in junit test, from lock to refresh. Change branch name in git review. Change-Id: I506de7a96cb3ee786839aca04ad67cdd7378832c Issue-ID: POLICY-872 Signed-off-by: Jim Hahn <jrh3@att.com>
2018-06-29Use DB time instead of jvm timeJim Hahn5-29/+65
Modified distributed locking code to use the DB time (i.e., "now()") when determining expiration times of locks. This will eliminate concerns that may arise from different timestamps on different JVMs. As part of the change, the expirationTime column was changed from BIGINT to TIMESTAMP. Rename 1810 sql scripts to 1811, to match release date. Change-Id: Ibfb15742f447133b001e4340027657ac202864a6 Issue-ID: POLICY-872 Signed-off-by: Jim Hahn <jrh3@att.com>
2018-06-27Add time limit to locking facilityJim Hahn6-305/+64
Modified the locking facility to add a time limit and remove the callback parameter. This affected both the default facility as well as the distributed locking feature. It will also require a change to the rules for Closed Loop. Changed testUnlock() to try locking with a different owner. Default feature API should be OPER_UNHANDLED. Put a few things back so-as not to break the drools-applications build. They can be removed once drools-applications is updated. Fix newlines in API java.

2018-06-18Add setXxx methods for @Property annotationJim Hahn1-41/+70
We'll be modifying the PropertyConfiguration class so that, instead of directly setting values in private fields, it will use public setXxx methods. Consequently, we have to add the setXxx methods to the PropertyConfiguration subclasses so that they're available when the superclass is modified policy/common.
