2018-02-20Sonar fixes to drools-pdpJim Hahn8-79/+81
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 McKiou7-137/+509
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.

2017-11-02Modify state-management propertiesv1.1.0Kevin McKiou1-1/+7
Patch 1: Removed hostPort and added server.TEST properties from feature-state-management.properties and modified associated code in IntegrityMonitor and properties in associated JUnit tests. Patch 2: Modified in response to comments from Jorge Hernandez. Including adding contant usage instead of strings and replacing generic exceptions with specific exceptions. Patch 3: Tied property constants to PolicyProperties. Added default property contants. Added error/warning log statemeents when something other than expected value is used. Add logging of all constant values for inspection in debugging. Issue-ID: POLICY-369 Change-Id: Ie2218b68761e0338642a2ed28ef840b1b6ece1a4 Signed-off-by: Kevin McKiou <km097d@att.com>
2017-09-25junits fixesJorge Hernandez1-1/+6
I found multiple issues from latest junit submissions when I built in my local that I tried to fix. 1. feature-test-transaction - prone to race conditions as we have experienced in some jenkins builds. There is an assert that checks if the thread is alive that monitors a policy controller kiesession sanity. The thread is very short-lived as it will exit right away since it detects that the underlying "drools session" does not have an attached rules artifact (brainless). Removed that check to fix the race condition. 2. With the increment of junits in the PolicyEngine.manager for multiple packages, it seems that the static instance is reused across junits (which surprised me), so configuration files that are not supposed to be read in junits for a package are read, and for example the lock state could propagate across junits. I tried to clean all that up to make sure that each junit deals with what is has created and state does not propagate to other junits. 3. feature-active-standy-management had a missing "junit" dependency. I generated the effective pom, and indeed did not show, some junits failed to compile in the test phase. Adding the test dependency fixed the problem. As a note, the feature-active-standy-management junits, take over 20 minutes to run. This time is excessive (see below): logs$ head -1 debug.log 2017-09-25 21:24:21.630 [main] DEBUG o.o.p.d.c.t.StandbyStateManagementTest.setUpClass(111) - setUpClass: userDir=/media/sf_jh1730/dev/open/LF/git/master/policy/drools-pdp/feature-active-standby-management logs$ tail -1 debug.log 2017-09-25 21:46:29.801 [Timer-46] DEBUG o.o.p.d.a.DroolsPdpsElectionHandler.run(919) - TimerUpdateClass.run.exit Change-Id: Ie3167e5f784f35f98fa08997e624c51f976b6501 Issue-ID: POLICY-109 Signed-off-by: Jorge Hernandez <jh1730@att.com>
