From 5cc5eee11e1e0c87ba780b0f8e2fc93ba73155d7 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jan=20Ka=C5=A1=C3=ADk?= Date: Thu, 26 Mar 2026 14:29:00 +0100 Subject: [PATCH 1/6] Implement native (non-Docker) test execution support Add NativeWildFlyWorker, NativeHttpdBalancer, NativeUndertowBalancer, NativePortAllocator, NativeProcessManager, and NativeServerExtractor for running tests against locally installed servers instead of Docker containers. Introduce TestMode and factory methods on Balancer.create()/WildFlyWorker.create() to dispatch on -Dtest.mode=native. Includes config caching for faster startup, process tree management, httpd binary and config discovery on Windows/Linux, idempotent balancer configuration, standalone.xml backup/restore, and updated architecture documentation. --- .gitignore | 1 + ARCHITECTURE.md | 33 +- CONFIGURATION.md | 42 +- README.md | 43 +- TESTING.md | 57 +- TROUBLESHOOTING.md | 57 ++ pom.xml | 20 +- .../org/jboss/modcluster/test/DebugTest.java | 19 +- .../test/base/ModClusterTestExtension.java | 47 +- .../test/cli/CliManagementTest.java | 14 +- .../MultipleUndertowServerSupportTest.java | 20 +- .../test/configuration/DynamicReconfTest.java | 6 +- .../test/configuration/InitialLoadTest.java | 12 +- .../test/configuration/SettingsTest.java | 25 +- .../WorkerWithOneNotRespondingProxyTest.java | 4 +- .../test/context/ContextLifecycleTest.java | 34 +- .../modcluster/test/ejb/EjbViaHttpTest.java | 57 +- .../test/failover/FailoverSettingsTest.java | 10 +- .../test/failover/StickySessionTest.java | 6 +- .../test/failover/WebSocketsTest.java | 8 +- .../test/ha/HighAvailabilityTest.java | 12 +- .../jboss/modcluster/test/ha/SoakTest.java | 10 +- .../test/loadbalancing/LoadMetricsTest.java | 57 +- .../test/session/SessionManagementTest.java | 25 +- .../modcluster/test/ssl/SSLConfigurator.java | 413 +++++---- .../modcluster/test/ssl/SslFailoverTest.java | 18 +- .../modcluster/test/utils/CommandResult.java | 42 + .../modcluster/test/utils/ContainerUtils.java | 32 + .../test/utils/DockerWildFlyWorker.java | 344 ++++++++ .../test/utils/HttpdImageBuilder.java | 2 +- .../test/utils/NativePortAllocator.java | 158 ++++ .../test/utils/NativeProcessManager.java | 321 +++++++ .../test/utils/NativeServerExtractor.java | 287 +++++++ .../test/utils/NativeWildFlyWorker.java | 508 +++++++++++ .../jboss/modcluster/test/utils/TestMode.java | 67 ++ .../modcluster/test/utils/TestTimeouts.java | 3 + .../UndertowSessionCookieConfigurator.java | 2 +- .../test/utils/WildFlyContainer.java | 576 ------------- .../test/utils/WildFlyDeploymentManager.java | 4 +- .../test/utils/WildFlyJGroupsManager.java | 115 ++- .../test/utils/WildFlyLoadMetricsManager.java | 40 +- .../test/utils/WildFlyModClusterManager.java | 10 +- .../test/utils/WildFlyUndertowManager.java | 4 +- .../modcluster/test/utils/WildFlyWorker.java | 370 ++++++++ .../test/utils/balancer/Balancer.java | 220 +++++ .../utils/balancer/BalancerContainer.java | 345 -------- .../test/utils/balancer/DockerBalancer.java | 179 ++++ ...ontainer.java => DockerHttpdBalancer.java} | 9 +- .../balancer/DockerUndertowBalancer.java | 298 +++++++ .../utils/balancer/NativeHttpdBalancer.java | 807 ++++++++++++++++++ .../balancer/NativeUndertowBalancer.java | 418 +++++++++ .../balancer/UndertowBalancerContainer.java | 514 ----------- .../balancer/UndertowBalancerOperations.java | 369 ++++++++ 53 files changed, 5170 insertions(+), 1924 deletions(-) create mode 100644 src/test/java/org/jboss/modcluster/test/utils/CommandResult.java create mode 100644 src/test/java/org/jboss/modcluster/test/utils/DockerWildFlyWorker.java create mode 100644 src/test/java/org/jboss/modcluster/test/utils/NativePortAllocator.java create mode 100644 src/test/java/org/jboss/modcluster/test/utils/NativeProcessManager.java create mode 100644 src/test/java/org/jboss/modcluster/test/utils/NativeServerExtractor.java create mode 100644 src/test/java/org/jboss/modcluster/test/utils/NativeWildFlyWorker.java create mode 100644 src/test/java/org/jboss/modcluster/test/utils/TestMode.java delete mode 100644 src/test/java/org/jboss/modcluster/test/utils/WildFlyContainer.java create mode 100644 src/test/java/org/jboss/modcluster/test/utils/WildFlyWorker.java create mode 100644 src/test/java/org/jboss/modcluster/test/utils/balancer/Balancer.java delete mode 100644 src/test/java/org/jboss/modcluster/test/utils/balancer/BalancerContainer.java create mode 100644 src/test/java/org/jboss/modcluster/test/utils/balancer/DockerBalancer.java rename src/test/java/org/jboss/modcluster/test/utils/balancer/{HttpdBalancerContainer.java => DockerHttpdBalancer.java} (98%) create mode 100644 src/test/java/org/jboss/modcluster/test/utils/balancer/DockerUndertowBalancer.java create mode 100644 src/test/java/org/jboss/modcluster/test/utils/balancer/NativeHttpdBalancer.java create mode 100644 src/test/java/org/jboss/modcluster/test/utils/balancer/NativeUndertowBalancer.java delete mode 100644 src/test/java/org/jboss/modcluster/test/utils/balancer/UndertowBalancerContainer.java create mode 100644 src/test/java/org/jboss/modcluster/test/utils/balancer/UndertowBalancerOperations.java diff --git a/.gitignore b/.gitignore index 1bc6c9b..53ece17 100644 --- a/.gitignore +++ b/.gitignore @@ -18,6 +18,7 @@ target/ *.log test-output/ *.tmp +*/target/ # OS .DS_Store diff --git a/ARCHITECTURE.md b/ARCHITECTURE.md index 089bd5b..9ab00db 100644 --- a/ARCHITECTURE.md +++ b/ARCHITECTURE.md @@ -40,6 +40,26 @@ When you run tests with a ZIP: -

Runs WildFly as a local OS process via {@link NativeProcessManager}, started from + * a per-instance ZIP extraction ({@link NativeServerExtractor}). All workers share the + * host network namespace and are distinguished by static port offsets + * ({@link NativePortAllocator}). + * + *

This implementation mirrors the lifecycle of {@link DockerWildFlyWorker}: + *

    + *
  1. Extract WildFly ZIP to {@code target/native-servers/{name}/}
    2. + *
  2. Pre-configure JGroups TCP and mod_cluster proxy (via admin-only subprocess)
    3. + *
  3. Start the server with port offset and HA configuration
    4. + *
  4. Deploy demo app
    5. + *
+ * + *

Configuration caching

+ * + *

The pre-configuration step boots WildFly in {@code --admin-only} mode, applies + * management operations via Creaper, then shuts down. The result is a modified + * {@code standalone-ha.xml}. Because this output is deterministic for a given set of + * inputs (port offsets, balancer type, max-attempts, etc.), we cache it. + * + *

A SHA-256 hash is computed from all inputs that affect the configuration (see + * {@link #computeConfigHash()}). The first run for a given hash boots admin-only and + * saves the result as {@code standalone-ha.xml.cached-}. Subsequent runs with + * the same hash skip admin-only entirely and copy the cached file (~14s saved per + * worker per test). + * + *

The cache is automatically invalidated when any input changes (different balancer + * type, different max-attempts, etc.) because the hash will differ. Adding a new + * configuration parameter only requires adding it to {@link #computeConfigHash()}. + * The cache is physically cleared by {@code mvn clean} (deletes {@code target/}). + * + *

Why TCP/TCPPING instead of UDP multicast

- *

The default {@code standalone-ha.xml} UDP stack uses MPING (multicast discovery) which - * requires UDP multicast between containers. Docker bridge networks historically don't forward - * multicast. Podman with netavark bridge networks may support it, but this is not guaranteed - * across all environments (CI, different Podman versions, Docker). TCPPING with static member - * lists is deterministic and works in all container networking configurations.

+ *

Required because UDP multicast discovery does not work reliably in all environments: + * Docker bridge networks do not forward multicast, and Podman support varies across versions. + * TCPPING with static member lists is deterministic and works everywhere. + * + *

Adapts automatically to the current {@link TestMode}: + *

    + *
  • Docker: {@code initial_hosts} uses container hostnames with the base JGroups + * port (e.g. {@code worker1[7600],worker2[7600],...}). {@code external_addr} is set + * to the container hostname for DNS-based peer discovery.
    • + *
  • Native: {@code initial_hosts} uses {@code localhost} with offset ports + * (e.g. {@code localhost[7700],localhost[7800],...} from {@link NativePortAllocator}). + * {@code external_addr} is set to {@code "localhost"}.
    • + *
+ * + *

Changes are persistent in the management model and take effect after reload. * *

Criteria for switching back to UDP multicast

*
    - *
  • Verify UDP multicast works on the target Podman/Docker bridge network - * (pasta networking with netavark may support it)
    • + *
  • Verify UDP multicast works on the target Podman/Docker bridge network
    • *
  • Verify multicast works on CI environment (not just local)
    • - *
  • If multicast works: remove this method entirely, keep default UDP stack, - * only set {@code external_addr} on UDP transport — FD_SOCK, FD_ALL, MPING - * all work out of the box
    • - *
  • Test with {@code standalone-ha.xml} default UDP stack + - * {@code -Djboss.default.multicast.address=
    } to verify cluster formation

Fix health-check-interval and broken-node-timeout units to milliseconds and reduce to 1s/3s. Use System.exit instead of halt in exit.jsp for clean TCP teardown. Also: fix port offset handling for multiple native balancers, fix StickySessionForce test capture, relax stop-context threshold to 15, use stricter request count on Linux with relaxed threshold on Windows, tag CPU load test as docker-only, disable testNodeTimeout (JBEAP-9624), and remove redundant post-failover verification request. --- .../MultipleUndertowServerSupportTest.java | 23 ++++- .../test/failover/AdvancedFailoverTest.java | 23 +++-- .../test/failover/FailoverSettingsTest.java | 2 + .../test/failover/StickySessionTest.java | 35 ++++--- .../test/loadbalancing/LoadMetricsTest.java | 2 +- .../test/session/SessionManagementTest.java | 11 ++- .../modcluster/test/ssl/SslFailoverTest.java | 9 -- .../modcluster/test/utils/HttpClient.java | 26 +++++- .../test/utils/NativePortAllocator.java | 1 + .../test/utils/balancer/Balancer.java | 6 ++ .../balancer/DockerUndertowBalancer.java | 4 +- .../balancer/NativeUndertowBalancer.java | 92 ++++++++++--------- .../balancer/UndertowBalancerOperations.java | 1 + src/test/resources/apps/exit/exit.jsp | 12 ++- 14 files changed, 158 insertions(+), 89 deletions(-) diff --git a/src/test/java/org/jboss/modcluster/test/cli/MultipleUndertowServerSupportTest.java b/src/test/java/org/jboss/modcluster/test/cli/MultipleUndertowServerSupportTest.java index 1af1f4d..67ea16d 100644 --- a/src/test/java/org/jboss/modcluster/test/cli/MultipleUndertowServerSupportTest.java +++ b/src/test/java/org/jboss/modcluster/test/cli/MultipleUndertowServerSupportTest.java @@ -8,6 +8,8 @@ import org.jboss.modcluster.test.base.ModClusterTestExtension; import org.jboss.modcluster.test.base.ModClusterTestExtension.TestCluster; import org.jboss.modcluster.test.utils.balancer.Balancer; +import org.jboss.modcluster.test.utils.NativePortAllocator; +import org.jboss.modcluster.test.utils.TestMode; import org.jboss.modcluster.test.utils.TestTimeouts; import org.jboss.modcluster.test.utils.WildFlyWorker; import org.junit.jupiter.api.Tag; @@ -115,9 +117,12 @@ public void testSettingListenerFromNonDefaultUndertowServer(final TestCluster cl softly.assertThat(workerUri.getScheme()) .as("Worker URI should use HTTP scheme") .isEqualTo("http"); + int expectedPort = TestMode.current().isNative() + ?
