From 18253e5bfbccc53baaa58e485704e9cb87855ac4 Mon Sep 17 00:00:00 2001 From: "Magnusen, Drew (dm741q)" Date: Thu, 7 Sep 2017 08:55:17 -0500 Subject: Addition of State Management Feature Patch 1:This commit adds the feature to provide node state management. There are also a couple of very minor cleanup items in feature-session-persistence which came up during review and testing. Patch 2: Cleaned up some logging statements and exceptions per comments by Pam Dragosh. Patch 3: Clean up per comments from Jorge Hernandez. Patch4: Added a default to ignoreErrors in RepositoryAudit. Patch 5: Rebase. Patch 6: Removed api-state-management/.gitignore Issue-ID: POLICY-155 Change-Id: I4fbfa33314d488ff46764931ca965f802b6a26d5 Signed-off-by: Kevin McKiou --- .../src/assembly/assemble_zip.xml | 76 +++ .../config/feature-state-management.properties | 82 +++ .../sql/18020-statemanagement.upgrade.sql | 74 +++ .../policy/drools/statemanagement/DbAudit.java | 218 ++++++++ .../statemanagement/DroolsPDPIntegrityMonitor.java | 398 +++++++++++++++ .../IntegrityMonitorRestManager.java | 110 ++++ .../drools/statemanagement/RepositoryAudit.java | 552 +++++++++++++++++++++ .../statemanagement/StateManagementFeature.java | 275 ++++++++++ .../statemanagement/StateManagementProperties.java | 64 +++ ...onap.policy.drools.core.PolicySessionFeatureAPI | 1 + ...p.policy.drools.features.PolicyEngineFeatureAPI | 1 + ...rools.statemanagement.StateManagementFeatureAPI | 1 + .../statemanagement/test/StateManagementTest.java | 245 +++++++++ .../src/test/resources/META-INF/persistence.xml | 39 ++ .../resources/feature-state-management.properties | 74 +++ .../src/test/resources/logback-test.xml | 47 ++ 16 files changed, 2257 insertions(+) create mode 100644 feature-state-management/src/assembly/assemble_zip.xml create mode 100644 feature-state-management/src/main/feature/config/feature-state-management.properties create mode 100644 feature-state-management/src/main/feature/db/statemanagement/sql/18020-statemanagement.upgrade.sql create mode 100644 feature-state-management/src/main/java/org/onap/policy/drools/statemanagement/DbAudit.java create mode 100644 feature-state-management/src/main/java/org/onap/policy/drools/statemanagement/DroolsPDPIntegrityMonitor.java create mode 100644 feature-state-management/src/main/java/org/onap/policy/drools/statemanagement/IntegrityMonitorRestManager.java create mode 100644 feature-state-management/src/main/java/org/onap/policy/drools/statemanagement/RepositoryAudit.java create mode 100644 feature-state-management/src/main/java/org/onap/policy/drools/statemanagement/StateManagementFeature.java create mode 100644 feature-state-management/src/main/java/org/onap/policy/drools/statemanagement/StateManagementProperties.java create mode 100644 feature-state-management/src/main/resources/META-INF/services/org.onap.policy.drools.core.PolicySessionFeatureAPI create mode 100644 feature-state-management/src/main/resources/META-INF/services/org.onap.policy.drools.features.PolicyEngineFeatureAPI create mode 100644 feature-state-management/src/main/resources/META-INF/services/org.onap.policy.drools.statemanagement.StateManagementFeatureAPI create mode 100644 feature-state-management/src/test/java/org/onap/policy/drools/statemanagement/test/StateManagementTest.java create mode 100644 feature-state-management/src/test/resources/META-INF/persistence.xml create mode 100644 feature-state-management/src/test/resources/feature-state-management.properties create mode 100644 feature-state-management/src/test/resources/logback-test.xml (limited to 'feature-state-management/src') diff --git a/feature-state-management/src/assembly/assemble_zip.xml b/feature-state-management/src/assembly/assemble_zip.xml new file mode 100644 index 00000000..f398829d --- /dev/null +++ b/feature-state-management/src/assembly/assemble_zip.xml @@ -0,0 +1,76 @@ + + + + + + feature-state-management + + zip + + + + false + + + + target + lib/feature + + feature-state-management-${project.version}.jar + + + + target/assembly/lib + lib/dependencies + + *.jar + + + + src/main/feature/config + config + 0644 + + + + src/main/feature/bin + bin + 0744 + + + + src/main/feature/db + db + 0744 + + + + src/main/feature/install + install + 0744 + + + + diff --git a/feature-state-management/src/main/feature/config/feature-state-management.properties b/feature-state-management/src/main/feature/config/feature-state-management.properties new file mode 100644 index 00000000..72c1fe22 --- /dev/null +++ b/feature-state-management/src/main/feature/config/feature-state-management.properties @@ -0,0 +1,82 @@ +### +# ============LICENSE_START======================================================= +# feature-state-management +# ================================================================================ +# Copyright (C) 2017 AT&T Intellectual Property.
