2018-02-20Sonar fixes to drools-pdpJim Hahn6-54/+50
Fixed most of the instances of the following sonar issues: Moved array designator Used diamond operator Changed System.out/err to use a logger Changed several Thread.sleep() in test code to a single sleep() Useless assignments Replaced comparison with "" to string.isEmpty() Merged if's Replaced ArrayList with List in method returns Reordered type modifiers Reordered constructor methods Defined constants for literals, or replaced them with method calls Removed "throws Xxx" for subclasses of RuntimeException Combined identical "catch" blocks Re-interrupted the current thread after catching an InterruptedException Removed tests against the literal "false" Fix indentation of new makeTopicOperError() method. Fix exception variable name in new methods, logNoUebEncoder() and logNoDmaapEncoder(). Change-Id: Iddae5210553662f733b67333b372dec8c3fe2c94 Issue-ID: POLICY-336 Signed-off-by: Jim Hahn <jrh3@att.com>

2017-12-13Fix issues blocking election handler threadKevin McKiou1-119/+55
This bug tracks the AT&T bug 355533. The symptom was that drools pdps that were backing each other up were becoming stuck in a standby state. The cause was that the election handler thread was being hung by a call to PolicyEngine.manager.deactivate which shuts down the topic endpoints when the drools pdp operational state transitions to disabled. Related problems were that the election handler heartbeat was NOT blocked when the main thread was blocked and the IntegrityMonitor forward progress counter was NOT blocked from incrementing when the election handler thread was blocked. This prevented the correct failover of the drools pdp to another healthy one. This change fixes the two causes of the thread blockage, moves the election handler heartbeat to the main thread and adds an interface (AllSeemsWell) which is called when the election handler has stalled/resumed. The AllSeemsWell interface will block forward progress counter increments when ALLNOTWELL and will resume forward progress counter increments when ALLSEEMSWELL. In addition, it reduces the run time of the StandbyStateManagementTest from approximately 8 minutes to approximately 2 minutes. Since this changes classes also changed by POLICY-444, this change must be merged before POLICY-444 can be merged.

2017-11-21Election Handler CleanupKevin McKiou2-6/+6
Under stress, the election handler in feature-active-standby-management may not get a chance to run within the allowed window causing the "watcher" thread to kill it and restart it. The run window is expanded. Also the pdp.updateInterval and pdp.checkInterval parameter values are increased appropriately in the properties file.

2017-09-21Addition of Active-Standby FeatureKevin McKiou17-0/+2905
Patch 1: Adds the active-standby feature to drools-pdp. This feature provides the state control of the drools-pdp nodes controlling failover with a site and across sites. Patch 2: Resolve merge conflict in packages/install/pom.xml and pom.xml. Patch 3: Resolved comments from Pamela Dragosh and Jorge Hernandez.
