Kirk Lund updated GEODE-9595: ----------------------------- Description: I found circular classpath dependencies in the testing targets. This results in modules such as geode-core adding geode-core*.jar to the classpath of the tests. Classes and resources are then available to the test JVM via the .jar file as well as the filesystem. Some debugging revealed that tests in affected modules end up loading classes and resources into testing JVMs from the .jar file instead of the filesystem, while other modules load them from the filesystem. was: I found circular classpath dependencies in the testing targets. This results in the module such as geode-core adding geode-core*.jar to the classpath of the tests. Classes and resources are then loaded into the test JVM from the .jar file instead of from the filesystem. This causes issues only in some tests such as AnalyzeSerializables integration tests. 1) Reproduce: a) Delete any line from geode-core/src/main/resources/org/apache/geode/internal/sanctioned-geode-core-serializables.txt b) Execute {{$ ./gradlew geode-core:integrationTest --tests AnalyzeCoreSerializablesIntegrationTest}} {{testSerializables}} will fail with {{FileSystemNotFoundException}}: {noformat} org.apache.geode.codeAnalysis.AnalyzeCoreSerializablesIntegrationTest > testSerializables FAILED java.nio.file.FileSystemNotFoundException at com.sun.nio.zipfs.ZipFileSystemProvider.getFileSystem(ZipFileSystemProvider.java:171) at com.sun.nio.zipfs.ZipFileSystemProvider.getPath(ZipFileSystemProvider.java:157) at java.nio.file.Paths.get(Paths.java:143) at org.apache.geode.codeAnalysis.AnalyzeDataSerializablesJUnitTestBase.mainResourceToSourcePath(AnalyzeDataSerializablesJUnitTestBase.java:260) at org.apache.geode.codeAnalysis.AnalyzeSerializablesJUnitTestBase.testSerializables(AnalyzeSerializablesJUnitTestBase.java:102) {noformat} 2) Debug: a) Open {{AnalyzeSerializablesJUnitTestBase}} in IntelliJ and put a breakpoint on the {{fail}} line at the end of {{testSerializables}} b) Execute debug AnalyzeCoreSerializablesIntegrationTest in IntelliJ c) When the debugger hits the breakpoint, add a watch for {{getModuleClass()}} This will show add an entry to Variables panel of type {{CoreSanctionedSerializablesService}} d) Double click on the variable {{CoreSanctionedSerializablesService}} and navigate to {{classLoader}} | {{ucp}} | {{path}} and note that {{file:/path/to/geode/geode-core/build/libs/geode-core-1.15.0-build.0.jar}} is present in the list which means that an integrationTest dependency directly or indirectly depends on geode-core e) Without stopping the debugger, navigate to {{mainResourceToSourcePath}} in {{AnalyzeDataSerializablesJUnitTestBase}} to put a breakpoint on the first line f) Let the test continue running until the debugger hits the second breakpoint g) Notice that the parameter {{buildResourceURI}} is pointing to the resource in the jar file instead of in the filesystem under {{geode-core/build/resources}} {noformat} jar:file:/path/to/geode/geode-core/build/libs/geode-core-1.15.0-build.0.jar!/org/apache/geode/internal/sanctioned-geode-core-serializables.txt {noformat} h) Execute {{$ ./gradlew geode-core:dependencies --configuration integrationTestRuntimeClasspath | less}} Note that the output is piped to less. Search for {{geode-core}} and note that the following dependencies will add the geode-core jar file as a dependency: {noformat} +--- project :geode-gfsh | +--- <snip> | +--- project :geode-core (*) {noformat} {noformat} +--- project :geode-dunit | +--- <snip> | +--- project :geode-core (*) | +--- <snip> | +--- project :geode-cq | | +--- <snip> | | +--- project :geode-core (*) | +--- project :geode-log4j | | +--- <snip> | | +--- project :geode-core (*) {noformat} {noformat} +--- project :geode-deployment:geode-deployment-legacy | +--- <snip> | +--- project :geode-core (*) {noformat} 3) Fix: a) Edit {{geode-core/build.gradle}} and retest until the bug no longer reproduces In the end, we find that the following changes are required: {noformat} - runtimeOnly(project(':geode-deployment:geode-deployment-legacy')) + runtimeOnly(project(':geode-deployment:geode-deployment-legacy')) { + exclude module: 'geode-core' + } {noformat} {noformat} - integrationTestImplementation(project(':geode-gfsh')) - integrationTestImplementation(project(':geode-junit')) - integrationTestImplementation(project(':geode-dunit')) - integrationTestImplementation(project(':geode-log4j')) + integrationTestImplementation(project(':geode-gfsh')) { + exclude module: 'geode-core' + } + integrationTestImplementation(project(':geode-junit')) { + exclude module: 'geode-core' + } + integrationTestImplementation(project(':geode-dunit')) { + exclude module: 'geode-core' + } + integrationTestImplementation(project(':geode-log4j')) { + exclude module: 'geode-core' + } {noformat} Since distributedTest also has a circular dependency in its classpath, we also add the only missing exclusion required there: {noformat} - distributedTestImplementation(project(':geode-gfsh')) + distributedTestImplementation(project(':geode-gfsh')) { + exclude module: 'geode-core' + } {noformat} b) Failure message of {{AnalyzeCoreSerializablesIntegrationTest}} should now be: {noformat} /path/to/geode/geode-core/build/resources/integrationTest/org/apache/geode/codeAnalysis/excludedClasses.txt Otherwise if this doesn't break backward compatibility, copy the file /path/to/geode/geode-core/build/integrationTest/test-worker-000000/actualSerializables.dat to /path/to/geode/geode-core/src/main/resources/org/apache/geode/internal/sanctioned-geode-core-serializables.txt. at org.apache.geode.codeAnalysis.AnalyzeSerializablesJUnitTestBase.testSerializables(AnalyzeSerializablesJUnitTestBase.java:100) {noformat} ...instead of the {{java.nio.file.FileSystemNotFoundException}} > Testing target classpaths may include multiple copies of build output > --------------------------------------------------------------------- > > Key: GEODE-9595 > URL: https://issues.apache.org/jira/browse/GEODE-9595 > Project: Geode > Issue Type: Bug > Components: build > Reporter: Kirk Lund > Assignee: Kirk Lund > Priority: Major > Labels: pull-request-available > > I found circular classpath dependencies in the testing targets.
