2018-06-213.0.1 policy-handler - cleaning sonar smellsAlex Shatov2-10/+10
- no change of functionality or API - removed the unused enum34>=1.1.6 from requirements.txt and setup.py - refactored run_policy.sh to redirect the stdout+stderr only once - refactoring to remove smells+vulnerability reported by sonar -- renamed Config.config to Config.settings -- removed the commented out code in customizer.py -- renamed StepTimer.NEXT to StepTimer.STATE_NEXT to avoid the naming confusion with the method StepTimer.next. Also renamed the related StepTimer.STATE_* constants -- refactored several functions by extracting methods to eliminate 4 out of 5 "brain-overload" smells reported by sonar -- moved the literal string for the socket_host "0.0.0.0" to a constant on the web-server to avoid the reported vulnerability Change-Id: I4c7d47d41c6ecd7cb28f6704f5dad2053c1ca7d6 Signed-off-by: Alex Shatov <alexs@att.com> Issue-ID: DCAEGEN2-515

2018-05-242.4.5 policy-handler - fix of unit tests2.0.0-ONAPbeijing2.0.0-ONAPAlex Shatov2-2/+5
- turned off test_gc unit-test on policy-handler to avoid get /gc/stats after shutdown of the web-server - made rougher comparison between execution time and timer interval Change-Id: Idcf6caae6f2a934dc2dc2d5a0fddd06543abd48a Signed-off-by: Alex Shatov <alexs@att.com> Issue-ID: DCAEGEN2-532
2018-05-182.4.4 policy-handler - log process memoryAlex Shatov4-140/+245
- in search of the memory leak that is falsely reported by docker stats, the following runtime logging was added = process_memory - rss and other memory of the current process = virtual_memory - the memory info of the whole system = thread_stacks - the active threads with the full stack on each Change-Id: I5f5ab3a477bfba3aecc5963547aa82da6269670b Signed-off-by: Alex Shatov <alexs@att.com> Issue-ID: DCAEGEN2-514
2018-05-102.4.3 policy-handler - try-catch top ExceptionsAlex Shatov3-21/+489
- added try-except for top level Exception into all threads of policy-handler to avoid losing the thread and tracking the unexpected crashes - rediscover the deployment-handler if not found before and after each catchup - refactored audit - separated metrics from audit - added more stats and runtime info to healthcheck = gc counts and garbage info if any detected = memory usage - to detect the potential memory leaks = request_id to all stats = stats of active requests - avoid reallocating the whole Queue of policy-updates after catchup = clear of the internal queue under proper lock Change-Id: I3fabcaac70419a68bd070ff7d591a75942f37663 Signed-off-by: Alex Shatov <alexs@att.com> Issue-ID: DCAEGEN2-483
2018-04-272.4.2 policy-handler - fixed race on step-timerAlex Shatov2-15/+40
- fixed the bug of unpredictably stopping of the periodic catch-up step-timer due to thread race condition in policy-handler = added critical sections under the reentrant lock on every group of local var change in step-timer - added more stats for healthcheck to track each type of job-operation separately = that helps narrowing down identifying the potential problems - unit test coverage 76% Change-Id: I92ddf6c92a3d225d9b87427e3edfb7f80669501a Signed-off-by: Alex Shatov <alexs@att.com> Issue-ID: DCAEGEN2-472

2018-03-202.4.0 dns based discovery of deployment-handlerAlex Shatov1-1/+2
- policy-handler uses dns based discovery of deployment-handler - driven by config - new data structure for deploy_handler section of config -- changed from string "deployment_handler" in 2.3.1 to structure in 2.4.0 deploy_handler : # name of deployment-handler service # used by policy-handler for logging target_entity : "deployment_handler" # url of the deployment-handler service # for policy-handler to direct the policy-updates to # - expecting dns to resolve the name # deployment_handler to ip address url : "http://deployment_handler:8188" - logic is backwards compatible with 2.3.1 format - removed import pip from audit -- import pip broken in pip 9.0.2 (2018-03-19) -- import pip conflicts with requests -- pip API is not officially supported -- see links for more https://github.com/pypa/pip/issues/5079 https://github.com/pypa/pip/issues/5081 Change-Id: Ifcaba6cfd714f3099ab7a25fe979a3696a6460fc Signed-off-by: Alex Shatov <alexs@att.com> Issue-ID: DCAEGEN2-404
2018-03-132.3.0 policy-handler - periodically catch_upAlex Shatov1-34/+5
- periodically catchup - interval is configurable = max_skips defines the number of times the catch_up message that is identical to previous one can be skipped - do not catchup more often than the interval even between the manual catchup and auto catchup - do not send the same catchup message twice in a row to the deployment-handler but not exceed a hard limit on catchup max_skips - catchup if the deployment-handler instance is changed Change-Id: I9a3fcc941e8a9e553abb3952dd882c37e0f5fdfe Signed-off-by: Alex Shatov <alexs@att.com> Issue-ID: DCAEGEN2-389
2018-03-082.2.0 policy-handler - customization per companyAlex Shatov1-4/+5
- added etc_customize/ folder and customize.sh script = customize.sh script is expected to be overridden by company to customize Docker image build = the whole etc_customize/ folder is copied into docker image = it is up to the company what to put into that folder - any files - added customize/ folder with CustomizeBase and Customize classes = CustomizeBase defines the interface and the default=ONAP behavior = CustomizeBase is owned by ONAP and should not be changed by the company = Customize inherits CustomizeBase = policy-handler instantiates Customize to get the customized behavior = Customize is owned by the company and should be changed by the company = ONAP is not going to change Customize = the methods of Customize are expected to be overridden by the company to change the behavior of the policy-handler = sample Customize class can be found in README.md = Company is allowed to add more files to customize/ folder if that is required for better structuring of their code as soon as it is invoked by the methods of Customize Change-Id: I46f8170afaaa48e1005e4398a768a781db0a0e6c Signed-off-by: Alex Shatov <alexs@att.com> Issue-ID: DCAEGEN2-379
